Description

Technical Field

[0001] This invention relates to the field of mine support engineering technology, and in particular to an automatic anchor cable unanchoring device. Background Technology

[0002] Currently, anchor cable removal machines are widely used in scenarios such as mines and steep cliffs in the wild. However, existing anchor cable removal machines still have some inconveniences in application. For example:

[0003] (1) The reliability is not high; specifically, when removing the anchor, the staff needs to rely on their work experience to judge whether the separation process of the anchor ring and the anchor plug needs to be continued with pressure; if the pressure is too small, it will be difficult to remove the anchor plug; if the pressure is too large, the anchor cable may be damaged.

[0004] (2) Low efficiency and high labor demand; specifically, when removing anchor cables in a roadway, one worker needs to first lift the anchor removal jack to the roadway roof and connect it to the anchor cable. Then, another worker waits for the anchor plug to come out of the anchor ring and then uses tools to remove the anchor plug. Due to the height of the roadway, another worker is needed to support the ladder. Therefore, the entire anchor removal operation requires at least three workers to complete; this consumes labor, increases the production cost of coal mining enterprises, and reduces efficiency.

[0005] (3) It has certain dangers; specifically, the anchor removal operation requires staff to manually remove the anchor plug. In addition, during the entire anchor removal and pressurization process, staff need to repeatedly climb ladders to determine whether to continue pressurizing. After the anchor is removed, the anchor must also be removed. Such repeated climbing of ladders will also threaten the personal safety of staff.

[0006] (4) The operation is complicated, the success rate is low, and the time is long. In particular, when the roadway tray is deformed or the anchor cable is forked, the anchor removal operation will be more difficult.

[0007] It is worth noting that (5) when the anchor cable is locked, the anchor plug is inserted into the anchor ring, so that the locking groove on the outer wall of the anchor plug is hidden inside the anchor ring or a small part of the locking groove is exposed in the anchor ring. Therefore, during the anchor removal operation, the anchor removal component cannot complete the anchor removal operation through the locking groove. Summary of the Invention

[0008] To address the aforementioned problems, this invention provides an automatic anchor cable retraction device, which overcomes the above-mentioned technical issues.

[0009] To achieve the above objectives, a first aspect of the present invention provides an automatic anchor cable retraction device, comprising:

[0011] The power mechanism drives the primary anchor removal mechanism to move the anchor plug out of the anchor ring to expose the locking groove on the anchor plug. The power mechanism also drives the secondary anchor removal mechanism to engage the locking groove and drag the anchor plug away from the anchor ring. The clutch mechanism disconnects and transmits the power output from the power mechanism to the secondary anchor removal mechanism before and after the locking groove is exposed.

[0012] Optionally, the power mechanism includes:

Furthermore, a clutch mechanism is disposed between the primary power structure and the secondary anchor retraction mechanism. The primary power structure is used to drive the primary anchor retraction mechanism to move the anchor plug out of the anchor ring to expose the locking groove opened on the anchor plug. When the clutch mechanism transmits the power output from the primary power structure to the secondary anchor retraction mechanism, the primary power structure drives the secondary anchor retraction mechanism to engage the locking groove.

[0014] A secondary power structure, connected to the secondary anchor retraction mechanism, allows the secondary power structure to drive the secondary anchor retraction mechanism to engage with the engagement groove when the primary power structure drives the secondary anchor retraction mechanism to drag the anchor plug away from the anchor ring.

The limiting claw is rotatably connected to the secondary anchoring base, and the rotatable connection point is located between the two ends of the limiting claw. The guide post moves back and forth along the length of the guide tube to drive one end of the limiting claw to rotate relative to the rotatable connection point to engage with or disengage from the locking groove.

[0034] The secondary elastic retainer has one end fixed to the secondary anchoring base and the other end connected between the other end of the limiting claw and the rotating connection point.

[0049] This invention discloses an automatic anchor removal device for anchor cables. Under the action of a power mechanism, the first-stage anchor removal mechanism moves the anchor plug out of the anchor ring to expose the locking groove on the anchor plug. Before this, the power transmission between the power mechanism and the second-stage anchor removal mechanism is disconnected based on a clutch mechanism. Then, under the driving action of the power mechanism, the clutch mechanism connects the power transmission between the power mechanism and the second-stage anchor removal mechanism. In this case, the power mechanism drives the second-stage anchor removal mechanism to engage the locking groove and drag the anchor plug away from the anchor ring, thereby automatically completing the anchor removal operation. This eliminates the need for manual removal of the anchor plug, reducing labor intensity and simplifying the anchor removal operation. It also eliminates the need for multiple people to cooperate in completing the anchor removal operation, saving production costs and reducing worker labor intensity. This lays the foundation for intelligent and unmanned anchor removal, improving production efficiency and safety during the anchor removal process. Furthermore, the first-stage anchor removal mechanism exposes the locking groove on the outer wall of the anchor plug, allowing the second-stage anchor removal mechanism to smoothly and efficiently engage the locking groove to complete the anchor removal operation.

[0064] To facilitate understanding of the embodiments of the present invention, the structure of the present invention will be described in detail below through several specific embodiments.

[0065] according to Figure 1-6 As shown, the first embodiment of the present invention provides an automatic anchor cable unanchoring device, which includes: a power mechanism, a primary unanchoring mechanism 13, a secondary unanchoring mechanism 14, and a clutch mechanism 15.

[0066] An automatic anchor release device for an anchor cable is included, comprising: a power mechanism, a primary anchor release mechanism 13 and a secondary anchor release mechanism 14 both connected to the power mechanism, and a clutch mechanism 15 connected between the power mechanism and the secondary anchor release mechanism 14; wherein, the power mechanism drives the primary anchor release mechanism 13 to move the anchor plug 19 out of the anchor ring 17 to expose the locking groove 171 opened on the anchor plug 19, and the power mechanism drives the secondary anchor release mechanism 14 to engage the locking groove 171 and drag the anchor plug 19 away from the anchor ring 17; the clutch mechanism 15 disconnects and transmits the power output from the power mechanism to the secondary anchor release mechanism 14 before and after the locking groove 171 is exposed.

[0067] Thus, under the action of the power mechanism, the primary anchor removal mechanism 13 first moves the anchor plug 19 out of the anchor ring 17 to expose the locking groove 171 on the anchor plug 19. Before this, the power transmission between the power mechanism and the secondary anchor removal mechanism 14 is disconnected based on the clutch mechanism 15. Then, under the driving action of the power mechanism, the clutch mechanism connects the power transmission between the power mechanism and the secondary anchor removal mechanism 14. In this case, the power mechanism drives the secondary anchor removal mechanism 14 to engage the locking groove 171 and drag the anchor plug 19 away from the anchor ring 17, thereby automatically completing the anchor removal operation. The automatic anchor plug removal eliminates the need for manual removal, reducing workload and simplifying the process. It also eliminates the need for multiple people to work together, saving production costs and reducing worker workload. This lays the foundation for intelligent and unmanned anchor removal, improving production efficiency and safety. Furthermore, the primary anchor removal mechanism 13 exposes the anchor plug 19 in the locking groove 171 on the outer wall, allowing the secondary anchor removal mechanism 14 to smoothly and efficiently engage the groove 171 to complete the anchor removal operation.

[0068] Specifically, the power mechanism is used to provide power. In this embodiment, it is not limited, as long as it can provide power to the first-level anchor retraction mechanism 13 and the second-level anchor retraction mechanism 14 respectively. For example, the power mechanism can be set as one or more of the following: motor, cylinder, hydraulic cylinder or spring reset mechanism.

[0069] In addition, both the primary anchor retraction mechanism 13 and the secondary anchor retraction mechanism 14 are connected to the power output end of the power mechanism, wherein the clutch mechanism 15 is connected between the power mechanism and the secondary anchor retraction mechanism 14.

[0070] The power mechanism drives the primary anchor removal mechanism 13 to move the anchor plug 19 out of the anchor ring 17 to expose the locking groove 171 opened on the anchor plug 19. Moreover, the power mechanism drives the secondary anchor removal mechanism 14 to engage the locking groove 171 and drag the anchor plug 19 away from the anchor ring 17. The clutch mechanism 15 disconnects and transmits the power output from the power mechanism to the secondary anchor removal mechanism 14 before and after the locking groove 171 is exposed.

[0071] Specifically, in the initial stage, based on the clutch mechanism 15, the power transmission between the power mechanism and the secondary anchor removal mechanism 14 is disconnected; therefore, during the anchor removal operation, the power mechanism first drives the primary anchor removal mechanism 13 to move the anchor plug 19 out of the anchor ring 17 to expose the locking groove 171 opened on the anchor plug 19; then, under the driving action of the power mechanism, the clutch mechanism 15 connects the power connection between the power mechanism and the secondary anchor removal mechanism 14, that is, the power mechanism can transmit power to the secondary anchor removal mechanism 14. Therefore, the power mechanism drives the secondary anchor removal mechanism 14 to engage the locking groove 171 and drag the anchor plug 19 away from the anchor ring 17, thereby completing the anchor removal operation.

[0072] Specifically, in another embodiment, the number of the aforementioned power mechanisms can be set to multiple, such as: the power mechanism is set to include two structures, such as: a primary power structure 11 and a secondary power structure, wherein the primary power structure 11 is connected to the primary anchor retraction mechanism 13 and the secondary anchor retraction mechanism 14, and the clutch mechanism 15 is disposed between the primary power structure 11 and the secondary anchor retraction mechanism 14, the primary power structure 11 is used to drive the primary anchor retraction mechanism 13 to move the anchor plug 19 out of the anchor ring 17 to expose the opening in the anchor ring 17. The anchor plug 19 has a locking groove 171. When the clutch mechanism 15 transmits the power output from the primary power structure 11 to the secondary anchor release mechanism 14, the primary power structure 11 drives the secondary anchor release mechanism 14 to engage the locking groove 171. The secondary power structure is connected to the secondary anchor release mechanism 14. When the primary power structure 11 drives the secondary anchor release mechanism 14 to engage the locking groove 171, the secondary power structure drives the secondary anchor release mechanism 14 to drag the anchor plug 19 away from the anchor ring 17.

[0073] Of course, in this embodiment, the primary power structure 11 and the secondary power structure are not limited. They only need to satisfy the requirement that they can drive the primary anchor retraction mechanism 13 and the secondary anchor retraction mechanism 14 to complete the anchor retraction operation and provide power for it. For example, the primary power structure 11 and the secondary power structure can be set to one or more of the following: motor, cylinder, hydraulic cylinder or spring reset mechanism.

[0074] It is worth noting that, in another embodiment, the primary power structure is configured as a hydraulic cylinder, which includes: a cylinder body 111, a piston 112 disposed inside the cylinder body 111, one end of the piston 112 extending out of the cylinder body 111, the piston 112 being movably connected to the cylinder body 111, and the piston 112 dividing the oil chamber inside the cylinder body 111 into a reset oil chamber 113 and an anchor-removing oil chamber 114, with one end of the piston 112 extending out of the cylinder body 111 through the cavity wall of the reset oil chamber 113; and the cylinder body 111 having a reset oil injection hole 116 communicating with the reset oil chamber 113 and an anchor-removing oil injection hole 115 communicating with the anchor-removing oil chamber 114, injecting oil into the anchor-removing oil chamber 114 and the reset oil chamber 113 respectively through the anchor-removing oil injection hole 115 and the reset oil injection hole 116, thereby changing the pressure difference between the reset oil chamber 113 and the anchor-removing oil chamber 114.

[0075] Furthermore, the left side of the aforementioned cylinder 111 is provided with an anchor seat 161 and a first-stage anchor retraction mechanism 13; wherein, the anchor seat 161 is fixed to the end of the piston 112 extending out of the cylinder 111; therefore, when oil is injected into the anchor retraction oil chamber 114 through the anchor retraction oil injection hole 115 and / or into the reset oil chamber 113 through the reset oil injection hole 116 so that there is a pressure difference between the reset oil chamber 113 and the anchor retraction oil chamber 114, the cylinder 111 moves as a mover to output power, while the piston 112 remains stationary relative to the anchor seat 161 as a stator because it is fixed to the anchor seat 161; therefore, the power output end of the first-stage power structure 11 is the power output end of the cylinder 111, which acts as a mover. Regarding the anchor seat 161 involved, in order to avoid redundancy, it will be described in detail later.

[0076] Specifically, under the action of the primary power structure 11, the primary anchor retraction mechanism 13 first moves the anchor plug 19 out of the anchor ring 17 to expose the locking groove 171 opened on the anchor plug 19. Before this, the power transmission between the primary power structure 11 and the secondary anchor retraction mechanism 14 is disconnected based on the clutch mechanism 15. Therefore, under the driving action of the primary power structure 11, the clutch mechanism 15 connects the power transmission between the primary power structure 11 and the secondary anchor retraction mechanism 14. In this case, the primary power structure 11 drives the secondary anchor retraction mechanism 14 to engage the locking groove 171, and the secondary... The power structure drives the secondary anchor removal mechanism 14 to drag the anchor plug 19 away from the anchor ring 17, thereby automatically completing the anchor removal operation. This eliminates the need for manual removal of the anchor plug, reducing workload and simplifying the process. It also eliminates the need for multiple people to cooperate in the anchor removal operation, saving production costs, improving efficiency, and enhancing safety. Furthermore, the primary anchor removal mechanism 13 allows the anchor plug 19 to be exposed in the locking groove 171 on the outer wall, enabling the secondary anchor removal mechanism 14 to smoothly and efficiently engage the locking groove 171 to complete the anchor removal operation.

[0077] Furthermore, in another embodiment, the first-stage anchor retraction mechanism 13 involved in the above embodiments is configured as follows:

[0078] Specifically, the primary anchor retraction mechanism 13 includes: an anchor retraction locking ring 132 and an anchor retraction fixing ring 131.

[0079] The anchor release locking ring 132 is sleeved on the outer periphery of the anchor cable 18; while the anchor release fixing ring 131 is fixed to the power output end of the primary power structure 11. The anchor release fixing ring 131 is sleeved on the outer wall of the anchor release locking ring 132. Moreover, the contact surfaces between the anchor release locking ring 132 and the anchor release fixing ring 131 are inclined (the axial conical surfaces of the anchor release locking ring 132 and the anchor release fixing ring 131 are in contact). Therefore, the primary power structure 11 can drive the anchor release fixing ring 131 to move back and forth along the length direction of the anchor cable 18, so that the anchor release fixing ring 131 drives the anchor release locking ring 132 to lock or release the anchor cable 18. Furthermore, when the anchor release fixing ring 131 locks the anchor cable 18, the anchor release fixing ring 131, the anchor release locking ring 132, and the anchor cable 18 are linked together.

[0080] Of course, in another embodiment, the following configuration may also be made: the primary anchor release mechanism 13 includes only the aforementioned anchor release locking ring 132, while the anchor release fixing ring 131 is included in the primary power structure 11.

[0081] Specifically, the anchoring retaining ring 131 and the anchoring locking ring 132 are configured as conical cylinders. The anchoring locking ring 132 is sleeved on the outer periphery of the anchor cable 18, and the anchoring retaining ring 131 is sleeved on the outer periphery of the anchoring locking ring 132. Moreover, the contact surfaces between the anchoring retaining ring 131 and the anchoring locking ring 132 are inclined (the anchoring retaining ring 131 and the anchoring locking ring 132 are in conical contact). For example, the anchoring locking ring 132 is conical along its axial direction, and the inner cavity of the anchoring retaining ring 131 is conical along its axial direction. Furthermore, the large-diameter opening and the small-diameter opening in the anchoring retaining ring 131 are located on the same side as the small-diameter opening and the large-diameter opening in the anchoring locking ring 132, respectively. Furthermore, the primary power structure 11 can drive the anchor-removing retaining ring 131 to move back and forth along the length of the anchor cable 18, causing the anchor-removing retaining ring 131 to press or release the anchor-removing locking ring 132. This allows the anchor-removing retaining ring 131 to press the inner radius of the anchor-removing locking ring 132 in the radial direction to lock the anchor cable 18 through the anchor-removing locking ring 132, or to release the inner radius of the anchor-removing locking ring 132 in the radial direction, allowing the anchor-removing locking ring 132 to reset. During the anchor-removing operation, the primary power... Structure 11 drives the anchor retraction fixing ring 131 to move in a preset direction, so that the anchor retraction fixing ring 131 presses the inner radius of the anchor retraction locking ring 132 in the radial direction. This causes the anchor retraction locking ring 132 to tightly press (i.e., lock) the anchor cable 18, thereby making the anchor retraction fixing ring 131, the anchor retraction locking ring 132, and the anchor cable 18 work together. In this case, the anchor retraction fixing ring 131, the anchor retraction locking ring 132, and the anchor cable 18 can continue to move in the driving direction when the primary power structure 11 drives the anchor retraction operation. Subsequently, with the anchor release locking ring 132 pressing the anchor cable 18, the primary power structure 11 continues to drive the anchor release fixing ring 131 to move toward the large-diameter end of the anchor release locking ring 132, thereby driving the anchor cable 18 to move along the moving direction of the anchor release fixing ring 131 during the anchor cable 18 locking process, so as to drive the anchor plug 19 to move out of the anchor ring 17 to expose the snap-fit ​​groove 171 opened on the anchor plug 19.

[0082] It is worth noting that in this embodiment, the contact surface between the anchoring fixing ring 131 and the anchoring locking ring 132 is set at an acute angle to the direction of movement (the preset direction mentioned below) when the anchoring fixing ring 131, the anchoring locking ring 132, and the anchor cable 18 move together.

[0083] In this embodiment, the shape of the anchor-retracting locking ring 132 and the shape of the anchor-retracting fixing ring 131 are not limited, as long as they meet the requirements of this embodiment. For example, the anchor-retracting fixing ring 131 can be configured as a conical cylinder (the inner hole of the anchor-retracting fixing ring 131 is conical). Furthermore, the anchor-retracting locking ring 132 includes multiple anchor clamps (e.g., three anchor clamps), and the axial section of each anchor clamp is conical. These multiple anchor clamps form a conical tube to form the anchor-retracting locking ring 132. In addition, the anchor-retracting fixing ring 131 and the anchor-retracting locking ring 132 are coaxially arranged, and the large-diameter opening and the small-diameter opening in the anchor-retracting fixing ring 131 are located on the same side as the small-diameter opening and the large-diameter opening in the anchor-retracting locking ring 132, respectively. It is worth noting that the multiple anchor clamps remain linked in the axial direction of the anchor-retracting locking ring 132.

[0084] Of course, during the anchor removal operation, the primary power structure 11 drives the anchor removal fixing ring 131 to move toward the large-diameter end of the anchor removal locking ring 132, so that the anchor removal fixing ring 131 gradually presses the anchor removal locking ring 132, and the anchor removal locking ring 132 (multiple anchor clamps) gradually presses the anchor cable 18. In this process, in order to avoid excessive displacement of the anchor removal locking ring 132 under the pushing action of the anchor removal fixing ring 131, in this embodiment, a friction surface (such as an annular groove) is provided on the inner surface of the anchor removal locking ring 132 close to the anchor cable 18 (the inner surface of the multiple anchor clamps), thereby increasing the friction between the inner surface of the anchor removal locking ring 132 (the inner surface of the multiple anchor clamps) and the anchor cable 18, so as to a certain extent, the connection strength between the anchor removal locking ring 132 (multiple anchor clamps) and the anchor cable 18 can be guaranteed, and the anchor removal locking ring 132 (multiple anchor clamps) can be limited.

[0085] Of course, in another embodiment, the following settings can also be made: To ensure the connection strength between the anchor-removing locking ring 132 and the anchor cable 18 when the anchor-removing fixing ring 131, the anchor-removing locking ring 132, and the anchor cable 18 are linked, and to limit the movement of the anchor-removing locking ring 132, the following settings are made: A locking ring limiting member 144 is provided at the large-diameter open end of the anchor-removing locking ring 132. When performing the anchor-removing operation (the first-stage power structure 11 drives the anchor-removing fixing ring 131 along its...), a locking ring limiting member 144 is provided. When the drive direction (the preset direction referred to in this document) is moved to cause the anchor release locking ring 132 to press against the anchor cable 18 (i.e., the anchor release fixing ring 131, the anchor release locking ring 132, and the anchor cable 18 are linked together), the locking ring limiting member 144 limits the large-diameter open end of the anchor release locking ring 132 in the length direction of the anchor cable 18; during the anchor release operation, the locking ring limiting member 144 limits the large-diameter open end of the anchor release locking ring 132 in the length direction of the anchor cable 18. In this situation, the primary power structure 11 drives the anchor-removing fixing ring 131 to move towards the large-diameter open end of the anchor-removing locking ring 132 along the length of the anchor cable 18. At this time, the locking ring limiting member 144 can limit the anchor-removing locking ring 132, allowing the anchor-removing fixing ring 131 to press against the anchor-removing locking ring 132, and the anchor-removing locking ring 132 can then tighten to press against the anchor cable 18, thereby realizing the anchor-removing fixing ring 131. The anchor release locking ring 132 and the anchor cable 18 are linked together. Subsequently, with the anchor release locking ring 132 pressing the anchor cable 18, the first-stage power structure 11 continues to drive the anchor release fixing ring 131 to move toward the large-diameter end of the anchor release locking ring 132, thereby driving the anchor cable 18 to move in the direction of movement of the anchor release fixing ring 131 during the anchor cable 18 locking process, so as to drive the anchor plug 19 to move out of the anchor ring 17 to expose the snap-fit ​​groove 171 opened on the anchor plug 19.

[0086] The locking ring limiting member 144 includes an elastic reset member 1441. Specifically, the elastic reset member 1441 is disposed at the large-diameter opening end of the anchor release locking ring 132 along the length of the anchor cable 18. Further, the locking ring limiting member 144 includes an elastic reset spring 14411 and a spring guide sleeve 14412. One end of the elastic reset spring 14411 is fixed inside the spring guide sleeve 14412, and the end of the spring guide sleeve 14412 away from the elastic reset spring 14411 abuts against the large-diameter opening end of the anchor release locking ring 132. The elastic force of the elastic reset spring 14411 is parallel to the length direction of the anchor cable 18. During the anchor removal operation, the locking ring limiting member 144 limits the large-diameter opening end of the anchor removal locking ring 132 along the length of the anchor cable 18. In this case, the primary power structure 11 drives the anchor removal fixing ring 131 to move towards the large-diameter opening end of the anchor removal locking ring 132 along the length of the anchor cable 18. At this time, the compression and rebound of the elastic return spring 14411 can limit the anchor removal locking ring 132, allowing the anchor removal fixing ring 131 to press against the anchor removal locking ring 132, and the anchor removal locking ring 132 to tighten and press against the anchor cable 18, thereby achieving the linkage of the anchor removal fixing ring 131, the anchor removal locking ring 132, and the anchor cable 18. The other end of the elastic return spring 14411 is fixed inside the primary power structure 11.

[0087] It is worth noting that during the reset operation of the automatic anchor release device, the primary power structure 11 applies a force in the opposite direction (opposite to the preset direction), and the anchor release fixing ring 131 moves in the opposite direction (opposite to the preset direction) along the length of the anchor cable 18, thereby releasing the clamping effect on the anchor release locking ring 132. During this process, to ensure that the anchor release locking ring 132 can smoothly disengage from the anchor cable 18, i.e., smoothly release the compression between the anchor release locking ring 132 and the anchor cable 18, one or more of the following settings can be made:

[0088] 1. The end of the spring guide sleeve 14412 away from the elastic return spring 14411 and the contact surface of the anchor release locking ring 132 are set at an obtuse angle to the elastic force direction of the elastic return member 1441 (the end of the spring guide sleeve 14412 away from the elastic return spring 14411 contacts the conical surface of the anchor release locking ring 132, and the outer contact is located on the anchor release locking ring 132), that is: the contact surface of the spring guide sleeve 14412 and the anchor release locking ring 132 (multiple anchor clamps) is set at an obtuse angle to the elastic force direction of the elastic return member 1441; therefore, when the anchor release fixing ring 131 releases the compression of the anchor release locking ring 132, In use, the elastic return spring 14411 releases its reverse elastic force, driving the spring guide sleeve 14412 to move in the opposite direction toward the anchor release locking ring 132. Since the contact surfaces of the spring guide sleeve 14412 and the anchor release locking ring 132 are set at an obtuse angle to the elastic force direction of the elastic return member 1441 (the spring guide sleeve 14412 contacts the conical surface of the anchor release locking ring 132, and the outer contact surface is located on the anchor release locking ring 132), the spring guide sleeve 14412 will arch the anchor clamp in the anchor release locking ring 132 to abut against the end of the spring guide sleeve 14412, thereby releasing the compression of the anchor cable 18 by the anchor release locking ring 132.

[0089] 2. The contact surfaces of the anchor opening plug component 16 and the anchor release locking ring 132 are set at an acute angle to the elastic force direction of the elastic reset member 1441; wherein, the anchor opening plug component 16 is located at the end of the anchor release locking ring 132 away from the elastic reset member 1441, and the anchor opening plug component 16 is fixed to the non-power output end of the primary power structure 11; therefore, when the squeezing action of the anchor release fixing ring 131 on the anchor release locking ring 132 is released, the elastic reset spring 14411 releases in the reverse elastic force, driving... The moving spring guide sleeve 14412 drives the retraction locking ring 132 to move in the opposite direction. Since the contact surface between the anchor opening plug component 16 and the retraction locking ring 132 is set at an acute angle with the elastic force direction of the elastic reset component 1441, the retraction locking ring 132 will slide onto the contact surface between the anchor opening plug component 16 and the retraction locking ring 132. This causes the end of the anchor clamp in the retraction locking ring 132 that abuts against the anchor opening plug component 16 to arch up, thereby releasing the compression of the anchor cable 18 by the retraction locking ring 132.

[0090] 3. The contact surfaces of the elastic reset member 1441 and the anchor release locking ring 132 are set at an obtuse angle to the elastic force direction of the elastic reset member 1441; and the contact surfaces of the anchor opening plug member 16 and the anchor release locking ring 132 are set at an acute angle to the elastic force direction of the elastic reset member 1441. Therefore, when the compression of the anchor release locking ring 132 by the anchor release fixing ring 131 is released, the elastic reset spring 14411 is released in the reverse direction, driving the spring guide sleeve 14412 to move in the opposite direction toward the anchor release locking ring 132. Since the contact surfaces of the spring guide sleeve 14412 and the anchor release locking ring 132 are set at an obtuse angle to the elastic force direction of the elastic reset member 1441, the spring guide sleeve 14412 will arch up the anchor clamp in the anchor release locking ring 132 to abut against the end of the spring guide sleeve 14412; at the same time, the spring guide sleeve is driven... 14412 reverses the movement of the anchor release locking ring 132. Because the contact surfaces of the anchor opening plug component 16 and the anchor release locking ring 132 are set at an acute angle to the elastic force direction of the elastic reset component 1441, the anchor release locking ring 132 will slide onto the contact surfaces of the anchor opening plug component 16 and the anchor release locking ring 132. This causes the end of the anchor clamp in the anchor release locking ring 132 that abuts against the anchor opening plug component 16 to arch up. That is, the two ends of the anchor release locking ring 132 arch up, thereby releasing the compression of the anchor cable 18 by the anchor release locking ring 132.

[0091] The anchor opening plug component 16 described above can be configured in any of the following ways:

[0092] 1. The anchor opening plug component 16 is an inclined surface formed on the anchor seat 161; moreover, the contact surface between the inclined surface (anchor opening plug component 16) and the anchor release locking ring 132 is set at an acute angle to the elastic force direction of the elastic reset member 1441, that is: the inclined surface is set at an acute angle to the elastic force direction of the elastic reset member 1441.

[0093] The anchor seat 161 is the base of the automatic anchor release device, and the first-stage power structure 11, the second-stage power structure, the first-stage anchor release mechanism 13 and the second-stage anchor release mechanism 14 are all fixed on the anchor seat 161.

[0094] Furthermore, the anchor seat 161 is located at the end of the anchor release locking ring 132 away from the elastic reset member 1441.

[0095] 2. According to Figure 3 As shown, the anchor opening plug component 16 includes: an anchor seat 161, an anchor retraction opening hole 162, an anchor retraction opening plug 163, and an anchor retraction opening spring 164.

[0096] The anchor seat 161 serves as the base of the automatic anchor release device, and the aforementioned primary power structure 11, secondary power structure, primary anchor release mechanism 13, and secondary anchor release mechanism 14 are all fixed to the anchor seat 161. Furthermore, the anchor seat 161 is located at the end of the anchor release locking ring 132 away from the elastic reset member 1441; moreover, the anchor release opening 162 is opened along the circumference of the anchor cable 18 at the end of the anchor seat 161 facing the anchor release locking ring 132; the shape and size of the anchor release opening 162 are adapted to the anchor release plug 163; the anchor release plug 163 is composed of multiple plug clips 166, which are arranged along the axial direction of the anchor cable 18 to form the anchor release plug 163, i.e., the shape and size of the anchor release opening 162 are adapted to the plug clips 166;

[0097] Furthermore, the anchor release opening 162 is composed of a first horizontal cavity and an inclined cavity, the length direction of which is set at an acute angle to the elastic force direction of the elastic reset member 1441; moreover, each opening plug clip 166 includes: a first plug plate 1661, a second plug plate 1662, and a third plug plate 1663, which are connected in sequence so that each opening plug clip 166 is arranged in a "Z" shape; moreover, the first plug... Plate 1661 is disposed in the first horizontal cavity, the second plug plate 1662 is disposed in the inclined cavity, and the third plug plate 1663 is parallel to the axial direction of the anchor cable 18. The end of the third plug plate 1663 away from the second plug plate 1662 extends out of the anchor release opening 162 and abuts against the end of the anchor release locking ring 132 away from the elastic reset member 1441. Moreover, the abutting surfaces of the protruding end of the third plug plate 1663 and the anchor release locking ring 132 are set at an acute angle to the elastic force direction of the elastic reset member 1441.

[0098] In addition, the anchor release spring 164 is fixed between the inner wall of the first horizontal cavity in the anchor release hole 162 and the first plug plate 1661, and the elastic force direction of the anchor release spring 164 is perpendicular to the first plug plate 1661.

[0099] In another embodiment, any of the following configurations can be made for the anchor opening plug component 16 described above:

[0100] according to Figure 4 As shown, the anchor opening plug component 16 includes: an anchor seat 161, an anchor retraction opening hole 162, an anchor retraction opening plug 163, an anchor retraction opening spring 1641, and a limiting seat.

[0101] The anchor seat 161 serves as the base of the automatic anchor release device, and the aforementioned primary power structure 11, secondary power structure, primary anchor release mechanism 13, and secondary anchor release mechanism 14 are all fixed to the anchor seat 161. Furthermore, the anchor seat 161 is located at the end of the anchor release locking ring 132 away from the elastic reset member 1441; moreover, the anchor release opening 162 is opened along the circumference of the anchor cable 18 at the end of the anchor seat 161 facing the anchor release locking ring 132; the shape and size of the anchor release opening 162 are adapted to the anchor release plug 163; the anchor release plug 163 is composed of multiple plug clips 166, which are arranged along the axial direction of the anchor cable 18 to form the anchor release plug 163, i.e., the shape and size of the anchor release opening 162 are adapted to the plug clips 166;

[0102] Furthermore, the anchor release opening 162 is composed of a first horizontal cavity and an inclined cavity, the length direction of which is set at an acute angle to the elastic force direction of the elastic reset member 1441; and each opening plug clip 166 includes a first plug plate 1661, a second plug plate 1662, and a third plug plate 1663, which are connected in sequence to make each opening plug clip 166 arranged in a "Z" shape; and the first plug plate 1661 is disposed in the first horizontal cavity, the second plug plate 1662 is arranged and fitted in the inclined cavity, the third plug plate 1663 is parallel to the axial direction of the anchor cable 18, and the end of the third plug plate 1663 away from the second plug plate 1662 extends out of the anchor release opening 162 and abuts against the anchor release locking ring 132. The end of the elastic reset member 1441; and, the contact surface between the protruding end of the third plug plate 1663 and the anchor release locking ring 132 is provided with a stop contact structure (the contact surface between the anchor opening plug component 16 and the anchor release locking ring 132 is provided with a stop contact structure), the stop contact structure includes: a plug vertical surface 167 and a plug inclined surface 168 provided at the protruding end of the third plug plate 1663 and a ring vertical surface and a ring inclined surface provided at the end of the anchor release locking ring 132 away from the elastic reset member 1441, the plug vertical surface 167 cooperates with the ring vertical surface, the plug inclined surface cooperates with the ring inclined surface, and the plug inclined surface 168 is set at an acute angle to the elastic force direction of the elastic reset member 1441, that is: when the anchor opening plug component 16 and the anchor release locking ring 132 are subjected to axial thrust, they have an outward movement tendency;

[0103] Furthermore, the anchor seat 161 is also provided with an opening plug limiting seat 165 at the anchor release opening hole 162. The opening plug limiting seat 165 extends toward the anchor cable 18 to cover the anchor release opening hole 162. Moreover, the aforementioned third plug plate 1663 is located between the opening plug limiting seat 165 and the anchor cable 18. The opening plug limiting seat 165 can restrict the displacement of the anchor release opening plug 163 along an axial direction perpendicular to the anchor cable 18, thereby preventing the anchor release opening plug 163 from falling off during the reset operation.

[0104] Each of the first plug plates 1661 has a groove on its outer wall, so that the portion of the anchor release plug 163 located in the first horizontal cavity has an outer ring groove. The anchor release spring 1641 is sleeved in the outer ring groove of the anchor release plug 163, and the free end of the anchor release spring 1641 is fixed to the inner wall of the first horizontal cavity; maintaining the minimum inner diameter of the multi-lobed anchor release plug 163 when it is not subjected to external force.

[0105] Therefore, when the compression of the anchor-removing fixing ring 131 on the anchor-removing locking ring 132 is released, the elastic return spring 14411 releases its reverse elastic force, driving the spring guide sleeve 14412 to drive the anchor-removing locking ring 132 to move in the reverse direction. Furthermore, because the protruding end of the third plug plate 1663 and the contact surface of the anchor-removing locking ring 132 are provided with a stop contact structure (the contact surface between the anchor opening plug component 16 and the anchor-removing locking ring 132 is provided with a stop contact structure), and the second plug plate 1662 is arranged and fitted in the inclined cavity, it ensures that the anchor-removing locking ring 132 has an outward tendency when subjected to the force of the spring 14411. Therefore, the anchor-removing locking ring 132 and the upper anchor opening plug component 16 slide together along the inclined cavity, thereby causing the anchor clamp in the anchor-removing locking ring 132 to abut against the... The end of the anchor opening plug component 16 is arched, which increases the inner diameter of the anchor release locking ring 132, thereby releasing the pressure of the anchor release locking ring 132 on the anchor cable 18. In this process, the structure of "the contact surface between the end of the spring guide sleeve 14412 away from the elastic return spring 14411 and the anchor release locking ring 132 is set at an obtuse angle to the elastic force direction of the elastic return member 1441 (the end of the spring guide sleeve 14412 away from the elastic return spring 14411 contacts the conical surface of the anchor release locking ring 132, and the outer contact is located on the anchor release locking ring 132)" can be combined to make both ends of the anchor clamp in the anchor release locking ring 132 arched, which increases the inner diameter of the anchor release locking ring 132, thereby releasing the pressure of the anchor release locking ring 132 on the anchor cable 18.

[0106] In another embodiment, based on the above embodiment, the clutch mechanism 15 involved above is configured as follows:

[0107] The clutch mechanism 15 includes: a guide tube 151, a guide post 152, a strip hole, and a limiting member 154. One end of the guide tube 151 is connected to the anchor removal fixing ring 131, and the length direction of the guide tube 151 is parallel to the length direction of the anchor cable 18. The guide post 152 is coaxially arranged with the guide tube 151. One end of the guide post 152 extends into and is slidably connected to the guide tube 151, and the other end of the guide post 152 is connected to the secondary anchor removal mechanism 14. The strip hole is formed on the side wall of the guide tube 151 along the length direction of the guide tube 151. One end of the limiting member 154 is fixed to the outer wall of the guide post 152, and the other end of the limiting member 154 extends into and is adapted to the strip hole.

[0108] Specifically, in this embodiment, the number of guide tubes 151 and guide posts 152 in the clutch mechanism 15 is not limited. Each guide tube 151 and guide post 152 corresponds one-to-one, as long as they meet the requirements of this embodiment. For example, if each guide tube 151 and guide post 152 in the clutch mechanism 15 is set to one, then this single guide tube 151 and guide post 152 will be used to disconnect and transmit the power mechanism output to the secondary anchor retraction mechanism 14 before and after the engagement groove 171 is exposed. The power; when the number of guide tubes 151 and guide posts 152 in the clutch mechanism 15 is set to at least two (when the number of guide tubes 151 and guide posts 152 in the clutch mechanism 15 is set to three), the guide tubes 151 and guide posts 152 are evenly distributed around the anchor cable 18, so that the power output of the power mechanism to the secondary anchor retraction mechanism 14 is disconnected and transmitted before and after the snap-fit ​​groove 171 is exposed, respectively, through the corresponding cooperation of the at least two guide tubes 151 and at least two guide posts 152.

[0109] Furthermore, in this embodiment, one end of the guide tube 151 is fixed to the anchor removal fixing ring 131, that is, the guide tube 151 and the anchor removal fixing ring 131 are linked together. Moreover, the guide post 152 is coaxially arranged with the guide tube 151. One end of the guide post 152 extends into and is slidably connected to the guide tube 151, and the other end of the guide post 152 is connected to the secondary anchor removal mechanism 14. Both the guide post 152 and the guide tube 151 are parallel to the length direction of the anchor cable 18. Furthermore, based on the above-mentioned strip hole and limiting member 154, when the limiting member 154 does not abut against the strip hole, the anchor cable 18 can be repositioned to a fixed position. When the strip hole is on both ends of the sidewall along the length of the anchor cable 18, the guide post 152 and the guide tube 151 are independent of each other; when the limiting member 154 abuts against either end of the strip hole along the length of the anchor cable 18, the guide post 152 and the guide tube 151 are linked, that is: during the anchor release operation, the primary power structure 11 continues to apply force to the anchor release fixing ring 131, and the anchor release fixing ring 131 continues to drive the guide tube 151 to move along a preset direction (the preset direction is: the direction of movement of the anchor release fixing ring 131 during the anchor cable 18 locking process). At this time, the guide tube 151 is in a moving state, while the guide post 152 is in a non-moving state. Until the side wall of the strip hole in the preset direction abuts against the limiting member 154, the guide tube 151 drives the guide post 152 to move along the preset direction (this preset direction is the direction of movement of the anchor-removing fixing ring 131 during the anchor cable 18 locking process). The guide post 152 drives the secondary anchor-removing mechanism 14 to engage the anchor plug 19 through the exposed engaging groove 171. Of course, during the reset operation of this automatic anchor-removing device, the primary power structure 11 applies a force in the opposite direction, causing the anchor-removing fixing ring 131 to... 1. Move in the opposite direction along the length of the anchor cable 18. As the anchor release ring 131 moves in the opposite direction, the guide tube 151 will also move in the opposite direction. At this time, the guide post 152 is in a non-moving state. Until the limiting member 154 abuts against the side wall of the strip hole in the opposite direction of the preset direction, the guide tube 151 will drive the guide post 152 to move in the opposite direction. The anchor release ring 131 is used to transmit the power between the output clutch mechanism 15 of the first-stage power structure 11, thereby completing the anchor release and reset operation. Therefore, the anchor release ring 131 also belongs to the first-stage power structure 11.

[0110] It is worth noting that a clutch through hole 1611 is provided on the anchor seat 161. The through hole is parallel to the length direction of the anchor cable 18. Moreover, the guide tube 151 and the guide post 152 are both movably inserted into the clutch through hole 1611.

[0111] Therefore, during the anchor removal operation, the primary power structure 11 drives the anchor removal fixing ring 131 to move toward the large-diameter end of the anchor removal locking ring 132. At this time, the locking ring limiting member 144 limits the large-diameter opening end of the anchor removal locking ring 132 in the length direction of the anchor cable 18, so that the anchor removal fixing ring 131 gradually presses against the anchor removal locking ring 132, thereby realizing that the anchor removal locking ring 132 presses against the anchor cable 18, so as to drive the anchor cable 18 to move along the preset direction (the preset direction is: the direction of movement of the anchor removal fixing ring 131 during the locking process of the anchor cable 18), thereby driving the anchor plug 19 to move out of the anchor ring 17 to expose the snap-fit ​​groove 171 opened on the anchor plug 19; then, the primary power structure The force applied to the anchoring retaining ring 131 by the mechanism 11 continues. Because the anchoring retaining ring 131, the anchoring locking ring 132, and the anchor cable 18 are linked, the locking ring limiting member 144 limits the large-diameter opening end of the anchoring locking ring 132 in the length direction of the anchor cable 18. Therefore, the anchoring retaining ring 131 and the anchoring locking ring 132 move along the anchor cable 18 in a preset direction (the preset direction is the direction of movement of the anchoring retaining ring 131 during the locking process of the anchor cable 18). Since one end of the guide tube 151 in the clutch mechanism 15 is connected to the anchoring retaining ring 131, the guide tube 151 and the anchoring retaining ring 131 are always linked. Therefore, under the drive of the first-stage power structure 11... As the anchor-removing retaining ring 131 moves toward the large-diameter end of the anchor-removing locking ring 132, gradually pressing the anchor-removing retaining ring 131 against the anchor-removing locking ring 132, the guide tube 151 also moves synchronously with the anchor-removing retaining ring 131 along a preset direction (the preset direction being the direction of movement of the anchor-removing retaining ring 131 during the locking of the anchor cable 18). At this time, the guide tube 151 is in a moving state, while the guide post 152 is in a non-moving state. This continues until the sidewall of the slotted hole abuts against the limiting member 154 in the preset direction. Then, the guide tube 151 drives the guide post 152 to move along the preset direction (the preset direction being the direction of movement of the anchor-removing retaining ring 131 during the locking of the anchor cable 18). 2. Drive the secondary anchor release mechanism 14 to engage the anchor plug 19 exposed in the engagement groove 171; Of course, during the reset operation of the automatic anchor release device, the primary power structure 11 applies a force in the opposite direction (opposite to the preset direction), and the anchor release fixing ring 131 moves in the opposite direction (opposite to the preset direction) along the length of the anchor cable 18. As the anchor release fixing ring 131 moves in the opposite direction (opposite to the preset direction), it will also drive the guide tube 151 to move in the opposite direction (opposite to the preset direction). At this time, the guide column 152 is in a non-moving state until the limiting member 154 abuts against the side wall of the strip hole in the opposite direction of the preset direction, at which point the guide tube 151 will drive the guide column 152 to move in the opposite direction.

[0112] In another embodiment, based on the above embodiment, the following settings are made for the secondary anchor retraction mechanism 14 involved above:

[0113] The secondary anchor retraction mechanism 14 includes: a secondary anchor retraction base 141, a limiting claw 142, and a secondary elastic retaining member 143. The secondary anchor retraction base 141 is connected to the secondary power structure.

[0114] Furthermore, one end of the limiting claw 142 is provided with a protrusion 1422 that engages with the locking groove 171, and the other end is connected to the guide post 152. Moreover, the limiting claw 142 is rotatably connected to the secondary anchoring base 141, and the rotation connection point is located between the two ends of the limiting claw 142. The guide post 152 moves back and forth along the length direction of the guide tube 151 to drive one end of the limiting claw 142 to rotate relative to the rotation connection point to engage with or disengage from the locking groove 171.

[0115] The secondary elastic retainer 143 can be exemplarily configured as a spring, with one end fixed to the secondary anchoring base 141 and the other end connected between the other end of the limiting claw 142 and the rotating connection point; when one end of the limiting claw 142 rotates relative to the rotating connection point to engage the locking groove 171, the secondary elastic retainer 143 is in a compressed state to drive the protrusion 1422 to lock the locking groove 171.

[0116] Specifically, in this embodiment, the secondary anchorage base 141, the limiting claw 142, and the secondary elastic retainer 143 each correspond one-to-one with the guide post 152. Furthermore, the end of the guide post 152 furthest from the guide tube 151 is connected to the limiting claw 142. This connection is not limited in this embodiment, as long as it meets the requirements of this embodiment. For example, the end of the guide post 152 furthest from the guide tube 151 can be hinged to the end of the limiting claw 142 furthest from the protrusion 1422. Of course, if at least one of the secondary anchorage base 141 and the limiting claw 142 is not located along the axial direction of the guide post 152, the end of the guide post 152 furthest from the guide tube 151 can be bent to accommodate the secondary anchorage base 141 and the limiting claw 142.

[0117] In another embodiment, based on the above embodiment, the secondary anchoring base 141 is provided with a first through hole, the guide post 152 passes through the first through hole, and the guide post 152 can move back and forth along the length direction of the first through hole, and the moving stroke of the guide post 152 is greater than the depth of the first through hole.

[0118] Furthermore, a guide limiting member 15211 is fixed at one end of the guide post 152 away from the guide tube 151, and the longitudinal area of ​​the guide limiting member 15211 is greater than the longitudinal area of ​​the first through hole.

[0119] Of course, for the above-mentioned connection, the following configuration may also be possible: the limiting claw 142 includes a strip-shaped body 1421, one end of which is provided with a protrusion 1422 (the limiting claw 142 has a protrusion 1422 at one end), and the other end of which is provided with a bent portion 1423 (the limiting claw 142 also has a bent portion 1423 at the other end). Moreover, a smooth arched portion 1424 is provided at the connection between the bent portion 1423 and the strip-shaped body 1421 (the smooth arched portion 1424 and the protrusion 1422 are respectively located on both sides of the rotational connection point between the limiting claw 142 and the secondary anchoring base 141). The protrusion 1422 and the bent portion 1423 are both located on the same side of the strip-shaped body 1421, and both the protrusion 1422 and the bent portion 1423 are connected to the smooth arched portion 1424. 4 are located on both sides of the protrusion 1422 body; and, the part of the guide post 152 that does not pass through the first through hole is provided with a mating block 15212; when the protrusion 1422 is not engaged with the engagement groove 171 on the anchor plug 19, the mating block 15212 is slidably connected to the side of the strip body 1421, at which time the secondary elastic retainer 143 is in a compressed state; when the protrusion 1422 is engaged with the engagement groove 171 on the anchor plug 19, the mating block 15212 slides past the smooth arched part 1424 and is slidably connected to the side of the bent part 1423, at which time the secondary elastic retainer 143 is released to a certain extent, but it is still in a compressed state, and the secondary elastic retainer 143 supports the rotation of the limiting claw 142 based on its reverse elastic force, so that the protrusion 1422 on the limiting claw 142 engages with the aforementioned engagement groove 171. Furthermore, the end of the guide post 152 away from the guide tube 151 passes through the first through hole opened on the secondary anchoring base 141 and is fixed with a guide limiting member 15211. Moreover, the longitudinal area of ​​the guide limiting member 15211 is greater than the longitudinal area of ​​the first through hole, and the travel of the guide post 152 is greater than the depth of the first through hole.

[0120] Specifically, during the anchor removal process, the primary power structure 11 drives the anchor removal fixing ring 131 to move toward the large-diameter end of the anchor removal locking ring 132. At this time, the locking ring limiting member 144 limits the large-diameter opening end of the anchor removal locking ring 132 in the length direction of the anchor cable 18, so that the anchor removal fixing ring 131 gradually presses against the anchor removal locking ring 132, thereby achieving the anchor removal locking ring 132 pressing against the anchor cable 18. This causes the anchor cable 18 to move along a preset direction (the preset direction is the direction of movement of the anchor removal fixing ring 131 during the anchor cable 18 locking process). Simultaneously, the guide tube 151 also moves synchronously with the anchor removal fixing ring 131 along the preset direction (the preset direction is the direction of movement of the anchor removal fixing ring 131 during the anchor cable 18 locking process). At this time, the guide tube 151 is in a moving state, while the guide post 152 is in a non-moving state, until the side wall of the strip hole in the preset direction abuts against the limiting member 154, at which point the guide tube 151 drives the guide post 152 to move. The guide post 152 moves along a preset direction (the preset direction is the direction of movement of the anchoring ring 131 during the locking process of the anchor cable 18). The mating block 15212 on the guide post 152 slides over the rounded arched part 1424 from the strip body 1421 of the limiting claw 142 and then slides to the side of the bent part 1423. At this time, the secondary elastic retainer 143 is released to a certain extent, but it is still in a compressed state. Moreover, the secondary elastic retainer 143 supports the rotation of the limiting claw 142 based on its reverse elastic force, so that the protrusion 1422 on the limiting claw 142 engages with the aforementioned engaging groove 171. Also, because the end of the guide post 152 away from the guide tube 151 passes through the first through hole opened on the secondary anchoring base 141 and is fixed with the guide limiting member 15211, and the longitudinal area of ​​the guide limiting member 15211 is larger than the longitudinal area of ​​the first through hole, the travel of the guide post 152 is greater than the depth of the first through hole. Therefore, in this embodiment, during the anchor removal operation, when the secondary elastic retainer 143 supports the rotation of the limiting claw 142 based on its reverse elastic force so that the protrusion 1422 on the limiting claw 142 engages with the aforementioned engaging groove 171, the primary power structure 11 continues to drive the anchor removal fixing ring 131, the anchor removal locking ring 132, and the anchor cable 18, which have formed a three-way linkage, to move together along a preset direction (the preset direction is the direction of movement of the anchor removal fixing ring 131 during the locking of the anchor cable 18), so that the guide tube 151 continues to drive the guide tube 151 to continue to drive the guide tube 151 to move along the preset direction (the preset direction is the direction of movement of the anchor removal fixing ring 131 during the locking of the anchor cable 18). The guide post 152 moves along a preset direction (the preset direction is the direction of movement of the anchoring ring 131 during the locking process of the anchor cable 18). At this time, between the guide post 152 and the secondary anchoring base 141, only the guide post 152 moves along the axial direction of the first through hole (the axial direction of the first through hole is parallel to the preset direction mentioned above) until the guide limiting member 15211 abuts against the secondary anchoring base 141 as the guide post 152 moves. This also allows the guide post 152 to drive the secondary anchoring base 141 to continue moving along the preset direction.

[0121] Of course, during the reset operation of the automatic anchor release device, the guide post 152 will move in the opposite direction of the preset direction. At this time, the guide post 152 is in a moving state, while the guide tube 151 is in a non-moving state. Until the limiting member 154 abuts against the side wall of the strip hole in the opposite direction of the preset direction, the mating block 15212 on the guide post 152 slides from the bent part 1423 of the limiting claw 142 over the smooth arched part 1424 and slides to the side of the strip body 1421. At this time, the secondary elastic retaining member 143 is compressed in the opposite direction, so that the limiting claw 142 rotates in the opposite direction around the above-mentioned rotating connection point, and the protrusion 1422 on the limiting claw 142 disengages from the locking groove 171 on the anchor plug 19, completing the reset operation.

[0122] Of course, in another embodiment, if at least one of the secondary anchoring base 141 and the limiting claw 142 is not located in the axial direction of the guide post 152, the end of the guide post 152 away from the guide tube 151 can be bent to fit the secondary anchoring base 141 and the limiting claw 142.

[0123] Specifically, the bent end of the guide post 152 is configured in a "Z" shape, comprising a first guide post 1521, a second guide post 1522, and a third guide post 1523. These three guide posts are sequentially and fixedly connected. The first guide post 1521 is parallel to the third guide post 1523, and the angle between the first guide post 1521 and the second guide post 1522 is complementary to the angle between the second guide post 1522 and the third guide post 1523. The end of the first guide post 1521 furthest from the second guide post 1522 passes through a first through hole in the secondary anchoring base 141 and is fixed with a guide limiting member 15211. The travel distance of the guide post 152 is greater than the depth of the first through hole. The third guide post 1523 and the guide tube 151 constitute the aforementioned clutch mechanism 15.

[0124] Of course, for the above-mentioned connection, the following configuration may also be possible: the limiting claw 142 includes a strip-shaped body 1421, one end of which is provided with a protrusion 1422 (the limiting claw 142 has a protrusion 1422 at one end), and the other end of which is provided with a bent portion 1423 (the limiting claw 142 also has a bent portion 1423 at the other end). Moreover, a smooth arched portion 1424 is provided at the connection between the bent portion 1423 and the strip-shaped body 1421 (the smooth arched portion 1424 and the protrusion 1422 are respectively located on both sides of the rotational connection point between the limiting claw 142 and the secondary anchoring base 141). The protrusion 1422 and the bent portion 1423 are both located on the same side of the strip-shaped body 1421, and both the protrusion 1422 and the bent portion 1423 are connected to the smooth arched portion 1424. Located on both sides of the protrusion 1422 body; and, in the part of the first guide post 1521 that does not pass through the first through hole, a mating block 15212 is provided; when the protrusion 1422 is not engaged with the locking groove 171 on the anchor plug 19, the mating block 15212 is slidably connected to the side of the strip body 1421, at which time, the secondary elastic retainer 143 is in a compressed state; when the protrusion 1422 is engaged with the locking groove 171 on the anchor plug 19, the mating block 15212 slides past the smooth arched part 1424 and then slides to the side of the bent part 1423, at which time, the secondary elastic retainer 143 is released to a certain extent, but it is still in a compressed state, and the secondary elastic retainer 143 supports the rotation of the limiting claw 142 based on its reverse elastic force, so that the protrusion 1422 on the limiting claw 142 engages with the aforementioned locking groove 171. Furthermore, the end of the first guide post 1521 that is away from the second guide post 1522 passes through the first through hole opened on the secondary anchoring base 141 and is fixed with a guide limiting member 15211. The longitudinal area of ​​the guide limiting member 15211 is larger than the longitudinal area of ​​the first through hole, and the travel of the guide post 152 is greater than the depth of the first through hole. The third guide post 1523 and the guide tube 151 constitute the aforementioned clutch mechanism 15.

[0125] Specifically, during the anchor removal process, the primary power structure 11 drives the anchor removal fixing ring 131 to move toward the large-diameter end of the anchor removal locking ring 132. At this time, the locking ring limiting member 144 limits the large-diameter opening end of the anchor removal locking ring 132 in the length direction of the anchor cable 18, so that the anchor removal fixing ring 131 gradually presses against the anchor removal locking ring 132, thereby achieving the anchor removal locking ring 132 pressing against the anchor cable 18, so as to drive the anchor cable 18 along a preset direction (the preset direction is: the movement of the anchor removal fixing ring 131 during the anchor cable 18 locking process). While the guide tube 151 moves in the moving direction, it also moves synchronously with the anchor-removing fixing ring 131 in a preset direction (the preset direction is the direction of movement of the anchor-removing fixing ring 131 during the locking process of the anchor cable 18). At this time, the guide tube 151 is in a moving state, while the guide posts 152 (first guide post 1521, second guide post 1522, and third guide post 1523) are in a non-moving state until the side wall of the strip hole in the preset direction abuts against the limiting member 154. Then, the guide tube 151 drives the guide posts 152 (first guide post 1521, second guide post 1522, third guide post 1523, third guide post 1523) to move. Guide post 1522 and third guide post 1523 move along a preset direction (the preset direction is the direction of movement of the anchor fixing ring 131 during the locking process of anchor cable 18). The mating block 15212 on the first guide post 1521 slides over the smooth arched part 1424 from the strip body 1421 of the limiting claw 142 and then slides to the side of the bent part 1423. At this time, the secondary elastic retainer 143 is released to a certain extent, but it is still in a compressed state. Moreover, the secondary elastic retainer 143 supports the limit based on its reverse elastic force. The positioning claw 142 rotates so that the protrusion 1422 on the limiting claw 142 engages with the aforementioned engaging groove 171; and because the end of the first guide post 1521 away from the second guide post 1522 passes through the first through hole opened on the secondary anchoring base 141 and is fixed with a guide limiting member 15211, the longitudinal area of ​​the guide limiting member 15211 is larger than the longitudinal area of ​​the first through hole, and the travel of the guide post 152 is greater than the depth of the first through hole; the third guide post 1523 and the guide tube 151 constitute the aforementioned clutch mechanism 15.Therefore, in this embodiment, during the anchor removal operation, when the secondary elastic retainer 143 supports the rotation of the limiting claw 142 based on its reverse elastic force so that the protrusion 1422 on the limiting claw 142 engages with the locking groove 171, the primary power structure 11 continues to drive the anchor removal fixing ring 131, the anchor removal locking ring 132, and the anchor cable 18, which have formed a three-way linkage, to move together along a preset direction (the preset direction is the direction of movement of the anchor removal fixing ring 131 during the locking of the anchor cable 18), so that the guide tube 151 continues to drive the guide post 152 along the preset direction (the preset direction is the direction of movement of the anchor removal ring 131 during the locking of the anchor cable 18). When the fixed ring 131 moves in the direction of movement, only the first guide post 1521, the second guide post 1522, and the third guide post 1523 constituting the guide post 152 will move along the axial direction of the first through hole (the axial direction of the first through hole is parallel to the aforementioned preset direction) between the first guide post 1521 and the secondary anchoring base 141, until the guide limiting member 15211 abuts against the secondary anchoring base 141 as the guide post 152 moves. This will also allow the first guide post 1521, the second guide post 1522, and the third guide post 1523 constituting the guide post 152 to drive the secondary anchoring base 141 to continue moving along the preset direction.

[0126] Of course, during the reset operation of the automatic anchor release device, the primary power structure 11 applies a force in the opposite direction, causing the anchor release fixing ring 131 to move in the opposite direction along the length of the anchor cable 18. As the anchor release fixing ring 131 moves in the opposite direction, it also drives the guide tube 151 to move in the opposite direction (in this document, this opposite direction refers to the direction opposite to the preset direction). At this time, the guide posts 152 (first guide post 1521, second guide post 1522, and third guide post 1523) are in a non-moving state until the limiting member 154 abuts against the strip hole in the preset direction. When the guide tube 151 moves against the side wall in the opposite direction, the guide tube 151 will drive the guide post 152 to move in the opposite direction as well. The mating block 15212 on the first guide post 1521 of the guide post 152 slides over the rounded arched part 1424 from the bent part 1423 of the limiting claw 142 and then slides to the side of the strip body 1421. At this time, the secondary elastic retainer 143 is compressed in the opposite direction, so that the limiting claw 142 rotates in the opposite direction around the above-mentioned rotating connection point. The protrusion 1422 on the limiting claw 142 disengages from the locking groove 171 on the anchor plug 19 and completes the reset operation.

[0127] In another embodiment, based on any of the above embodiments, the following settings are made for the aforementioned secondary power structure:

[0128] The secondary power structure includes: a second through hole 1412, a guide rail 122, a secondary anchoring elastic element 123, and a limiting structure 124.

[0129] The second through hole 1412 is formed on the secondary anchorage base 141, and the length direction of the second through hole 1412 is parallel to the length direction of the first through hole; the guide rail 122 passes through the second through hole 1412, and the secondary anchorage base 141 can move back and forth along the length direction of the guide rail 122 based on the second through hole 1412; the secondary anchorage elastic member 123 is sleeved on the outer wall of the guide rail 122, and the secondary anchorage elastic member 123 and the guide limiting member 15211 are located on the secondary anchorage base 141. On the same side of 1, one end of the secondary anchoring elastic member 123 abuts against the secondary anchoring base 141. Before the guide limiting member 15211 abuts against the secondary anchoring base 141, the secondary anchoring elastic member 123 is in a compressed state. The limiting structure 124 is disposed between the guide rail 122 and the inner wall of the second through hole 1412. Therefore, before and after the guide limiting member 15211 abuts against the secondary anchoring base 141, the limiting structure 124 respectively constructs and releases the linkage between the secondary anchoring base 141 and the guide rail 122.

[0130] In the above embodiments, the limiting structure 124 is not limited, as long as it meets the requirements of this embodiment. Therefore, in another embodiment, based on the above embodiments, the limiting structure 124 is configured as follows:

[0131] The limiting structure 124 includes: a limiting hole 1241, a limiting elastic element, a limiting clip, and a limiting adapter hole.

[0132] The limiting hole 1241 is located on the inner wall of the second through hole 1412; the limiting elastic member is disposed within the limiting hole 1241, and the length direction of the limiting elastic member is parallel to the length direction of the limiting hole 1241; the limiting clip is connected to the elastic end of the limiting elastic member; the limiting adapter hole is located on the outer wall of the guide rail 122, and the shape and size of the limiting adapter hole are adapted to the groove and size of the limiting clip; therefore, when the limiting clip engages with the limiting adapter hole, the secondary anchoring elastic member 123 is in a compressed state, and the secondary anchoring base 141 and the guide rail 122 are linked, that is: when the limiting clip engages with the limiting adapter hole, the secondary anchoring base 141 and the guide rail 122 are in a relatively stationary state; when the limiting clip disengages from the limiting adapter hole, the secondary anchoring base 141 and the guide rail 122 form a sliding connection.

[0133] Specifically, in the anchor removal process described in any of the above embodiments, before the guide limiting member 15211 abuts against the secondary anchor removal base 141, the limiting elastic member is in a compressed state to support the limiting clip and the limiting adapter hole, so that the secondary anchor removal base 141 and the guide rail 122 remain linked, that is, the secondary anchor removal base 141 and the guide rail 122 are in a relatively stationary state; after the guide limiting member 15211 abuts against the secondary anchor removal base 141, under the action of the guide limiting member 15211, the guide post 152 can drive the secondary anchor removal base 141 to continue to move along the preset direction, thereby pushing the limiting clip between the secondary anchor removal base 141 and the guide rail 122 to disengage from the limiting adapter hole, and the limiting elastic member is compressed in the opposite direction, thereby releasing the linkage between the secondary anchor removal base 141 and the guide rail 122. The system allows the secondary anchoring base 141 to slide in connection with the guide rail 122. At this time, the compressed secondary anchoring elastic element 123 is released from pressure. Under the elastic force of the secondary anchoring elastic element 123, it drives the secondary anchoring base 141 to continue moving along the preset direction (at this time, the guide post 152 also continues to drive the secondary anchoring base 141 to continue moving along the preset direction). Because the protrusion 1422 of the limiting claw 142 engages with the engaging groove 171 on the anchor plug 19, the limiting claw 142 is fixed to the secondary anchoring base 141. Therefore, as the secondary anchoring base 141 moves in the preset direction, it also drives the anchor plug 19 to continue moving in the preset direction, thereby causing the anchor plug 19 to disengage from the anchor ring 17, thus completing the anchoring operation.

[0134] Of course, during the reset operation of the automatic anchor release device, the primary power structure 11 applies a force in the opposite direction, causing the anchor release fixing ring 131 to move in the opposite direction along the length of the anchor cable 18, thereby releasing the squeezing effect on the anchor release locking ring 132. As the anchor release fixing ring 131 moves in the opposite direction, the guide tube 151 will also move in the opposite direction. At this time, the guide post 152 is in a non-moving state until the limiting member 154 abuts against the side wall of the strip hole in the opposite direction of the preset direction. Then, the guide tube 151 will drive the guide post 152 to move in the opposite direction, so that the mating block 15212 on the guide post 152 (or the first guide post 1521 on the guide post 152) slides from the bent part 1423 of the limiting claw 142 over the smooth arched part 1424 and then slides to connect to the strip body 1421. On the side, at this time, the secondary elastic retainer 143 is compressed in the reverse direction, causing the limiting claw 142 to rotate in the opposite direction around the aforementioned swivel connection point; then, the guide post 152 continues to move in the opposite direction with the guide tube 151 until the guide limiting member 15211 on the guide post 152 disengages from the secondary anchoring base 141 (or, the guide limiting member 15211 disengages from the secondary anchoring base 141 and the second guide post 1522 on the guide post 152 abuts against the secondary anchoring base 141), causing the guide post 152 to push the secondary anchoring base 141 to move in the opposite direction on the guide rail 122 until the limiting clip between the secondary anchoring base 141 and the guide rail 122 slides back into the limiting adapter hole. At this time, the secondary anchoring elastic member 123 is in compression reset, thus completing the reset operation of the automatic anchoring device.

[0135] In another embodiment, to further detail the structure of the automatic anchor retraction device, its retraction operation, and its reset operation, a hydraulic cylinder is used as an example for illustration:

[0136] Specifically, the automatic anchor release device includes: a primary anchor release mechanism 13, a secondary anchor release mechanism 14, a clutch mechanism 15, a secondary power structure, and a primary power structure 11 configured as a hydraulic cylinder.

[0137] The hydraulic cylinder includes: a cylinder body 111, a piston 112 disposed inside the cylinder body 111, one end of the piston 112 extending out of the cylinder body 111, the piston 112 being movably connected to the cylinder body 111, and the piston 112 dividing the oil chamber inside the cylinder body 111 into a reset oil chamber 113 and an anchor removal oil chamber 114, one end of the piston 112 extending out of the cylinder body 111 through the cavity wall of the reset oil chamber 113; and the cylinder body 111 having an anchor removal oil injection hole 115 communicating with the reset oil chamber 113 and a reset oil injection hole 116 communicating with the anchor removal oil chamber 114, oil being injected into the anchor removal oil chamber 114 and the reset oil chamber 113 respectively through the anchor removal oil injection hole 115 and the reset oil injection hole 116, thereby changing the pressure difference between the reset oil chamber 113 and the anchor removal oil chamber 114. Furthermore, in this embodiment, the hydraulic cylinder is placed horizontally, so that the reset oil chamber 113 and the anchor release oil chamber 114 are distributed left and right as an example for further explanation. Moreover, the cylinder body 111 has a cavity built into the center to accommodate the anchor cable 18. This cavity is isolated from the aforementioned anchor release oil chamber 114 and reset oil chamber 113 and has no communication with them. This cavity is placed in the left and right direction. Therefore, in this embodiment, the connecting block and the piston 112 can both be arranged in a cylindrical shape. The central axis of the cylindrical connecting block and the piston 112 is collinear with the central axis of the cavity.

[0138] The cavity contains a locking ring limiting member 144. Specifically, the elastic return spring 14411 in the locking ring limiting member 144 is horizontally disposed in the cavity, and the spring guide sleeve 14412 in the locking ring limiting member 144 is connected to the left side of the elastic return spring 14411.

[0139] Furthermore, the left side of the aforementioned cylinder 111 is provided with an anchor seat 161 and a first-stage anchor retraction mechanism 13; wherein, the anchor seat 161 is fixed to the end of the piston 112 extending out of the cylinder 111; therefore, when oil is injected into the anchor retraction oil chamber 114 through the anchor retraction oil injection hole 115 and / or into the reset oil chamber 113 through the reset oil injection hole 116 so that there is a pressure difference between the reset oil chamber 113 and the anchor retraction oil chamber 114, the cylinder 111 moves as a mover to output power, while the piston 112 remains stationary relative to the anchor seat 161 as a stator because it is fixed to the anchor seat 161.

[0140] The primary anchor retraction mechanism 13 includes an anchor retraction locking ring 132 and an anchor retraction fixing ring 131. The anchor retraction locking ring 132 is fitted onto the outer periphery of the anchor cable 18. The anchor retraction fixing ring 131 is fixed to the cylinder 111 and fitted onto the outer wall of the anchor retraction locking ring 132. The contact surfaces between the anchor retraction locking ring 132 and the anchor retraction fixing ring 131 are inclined. Both the anchor retraction fixing ring 131 and the anchor retraction locking ring 132 are tapered. The anchor retraction locking ring 132 is formed by three anchor clamps connected in a closed loop. The large-diameter opening and the small-diameter opening in the anchor retraction fixing ring 131 are located on the same side as the small-diameter opening and the large-diameter opening in the anchor retraction locking ring 132, respectively. It is worth noting that the anchor release locking ring 132 is located to the left of the spring guide sleeve 14412 in the locking ring limiting member 144, and the contact surface of the spring guide sleeve 14412 and the anchor release locking ring 132 is set at an obtuse angle to the elastic force direction of the elastic reset member 1441.

The opening plug limiting seat 165 extends toward the anchor cable 18 to cover the anchor release opening hole 162. Moreover, the aforementioned third plug plate 1663 is located between the opening plug limiting seat 165 and the anchor cable 18. The opening plug limiting seat 165 can restrict the displacement of the anchor release opening plug 163 along an axial direction perpendicular to the anchor cable 18, thereby preventing the anchor release opening plug 163 from falling off during the reset operation.

[0145] Each of the first plug plates 1661 has a groove on its outer wall, so that the portion of the anchor release plug 163 located in the first horizontal cavity has an outer ring groove. The anchor release spring 1641 is sleeved in the outer ring groove of the anchor release plug 163, and the free end of the anchor release spring 1641 is fixed to the inner wall of the first horizontal cavity; maintaining the minimum inner diameter of the multi-lobed anchor release plug 163 when it is not subjected to external force.

One end of the limiting member 154 is fixed to the outer wall of the guide post 152, and the other end of the limiting member 154 extends into and is adapted to the strip hole. Specifically, one end of the guide tube 151 is connected to the anchoring fixing ring 131, one end of the guide post 152 extends into and is slidably connected to the guide tube 151, and the other end is provided with a first guide post 1521, a second guide post 1522, and a third guide post 1523. The first guide post 1521, the second guide post 1522, and the third guide post 1523 are fixedly connected in sequence. Moreover, the first guide post 1521 is parallel to the third guide post 1523, and the angle between the second guide post 1522 and the second guide post 1523 is complementary to the angle between the second guide post 1522 and the third guide post 1523. The end of the first guide post 1521 that is away from the second guide post 1522 passes through the first through hole opened on the secondary anchoring base 141 in the secondary anchoring mechanism 14 and is fixed with a guide limiting member 15211. Moreover, the travel of the guide post 152 is greater than the depth of the first through hole. The third guide post 1523 and the guide tube 151 constitute the aforementioned clutch mechanism 15.

[0147] The secondary anchoring mechanism 14 includes: the aforementioned secondary anchoring base 141, a limiting claw 142, and a secondary elastic retaining member 143 configured as a spring. Specifically, one end of the limiting claw 142 is provided with a protrusion 1422 that mates with the locking groove 171, and the other end is connected to the guide post 152. Moreover, the limiting claw 142 is rotatably connected to the secondary anchoring base 141, and the rotatable connection point is located between the two ends of the limiting claw 142. The limiting claw 142 includes a strip-shaped body 1421, one end of which is provided with a protrusion 1422 (one end of the limiting claw 142 is provided with a protrusion 1422), and the other end of which is provided with a bent portion 1423 (the other end of the limiting claw 142 is also provided with a bent portion 142). 3) Furthermore, a smooth arched portion 1424 is provided at the connection between the bent portion 1423 and the strip body 1421 (the smooth arched portion 1424 and the protrusion 1422 are respectively located on both sides of the rotation connection point between the limiting claw 142 and the secondary anchoring base 141), wherein the protrusion 1422 and the bent portion 1423 are both located on the same side of the strip body 1421, and the protrusion 1422 and the bent portion 1423 are located on both sides of the body of the protrusion 1422 along with the smooth arched portion 1424; moreover, a mating block 15212 is provided at the part of the guide post 152 (first guide post 1521) that does not pass through the first through hole.

[0148] The secondary dynamic structure includes: a second through hole 1412 formed on the secondary anchorage base 141, a guide rail 122, a secondary anchorage elastic element 123, and a limiting structure 124. Specifically, the length direction of the second through hole 1412 is parallel to the length direction of the first through hole; the guide rail 122 passes through the second through hole 1412, and based on the second through hole 1412, the secondary anchorage base 141 can move back and forth along the length direction of the guide rail 122; the secondary anchorage elastic element 123 is sleeved on the outer wall of the guide rail 122, and the secondary anchorage elastic element 123 and the guide limiting element 15211 are located on the same side of the secondary anchorage base 141. One end of component 123 abuts against the secondary anchoring base 141. Before the guide limiting component 15211 abuts against the secondary anchoring base 141, the secondary anchoring elastic component 123 is in a compressed state. The limiting structure 124 is disposed between the guide rail 122 and the inner wall of the second through hole 1412. Therefore, before and after the guide limiting component 15211 abuts against the secondary anchoring base 141, the limiting structure 124 respectively constructs and releases the linkage between the secondary anchoring base 141 and the guide rail 122.

[0149] The limiting structure 124 includes: a limiting hole 1241, a limiting elastic element, a limiting clip, and a limiting adapter hole. The limiting hole 1241 is located on the inner wall of the second through hole 1412; the limiting elastic member is disposed within the limiting hole 1241, and the length direction of the limiting elastic member is parallel to the length direction of the limiting hole 1241; the limiting clip is connected to the elastic end of the limiting elastic member; the limiting adapter hole is located on the outer wall of the guide rail 122, and the shape and size of the limiting adapter hole are adapted to the groove and size of the limiting clip; therefore, when the limiting clip engages with the limiting adapter hole, the secondary anchoring elastic member 123 is in a compressed state, and the secondary anchoring base 141 and the guide rail 122 are linked, that is: when the limiting clip engages with the limiting adapter hole, the secondary anchoring base 141 and the guide rail 122 are in a relatively stationary state; when the limiting clip disengages from the limiting adapter hole, the secondary anchoring base 141 and the guide rail 122 form a sliding connection.

[0150] Specifically, during the anchor removal process, oil is injected into the anchor removal oil chamber 114 through the anchor removal oil injection hole 115. Because the piston 112 is fixed to the anchor seat 161, the cylinder 111 moves to the right. Since the cylinder 111 is fixed to the anchor removal fixing ring 131, the cylinder 111 drives the anchor removal fixing ring 131 to move toward the large-diameter end of the anchor removal locking ring 132. At this time, the locking ring limiting member 144 limits the large-diameter opening end of the anchor removal locking ring 132 in the length direction of the anchor cable 18, so that the anchor removal fixing ring 131 gradually presses the anchor removal locking ring. Ring 132, thereby achieving the tightening of anchor cable 18 by the anchor release locking ring 132, so that the anchor cable 18 moves along a preset direction (the preset direction is the moving direction of the anchor release fixing ring 131 during the anchor cable 18 locking process). At the same time, guide tube 151 also moves synchronously with the anchor release fixing ring 131 along the preset direction. At this time, guide tube 151 is in a moving state, while guide post 152 (first guide post 1521, second guide post 1522 and third guide post 1523) is in a non-moving state, until the side wall of the strip hole in the preset direction abuts the limit. When the positioning member 154 is in position, the guide tube 151 drives the guide posts 152 (first guide post 1521, second guide post 1522 and third guide post 1523) to move in a preset direction. The mating block 15212 on the first guide post 1521 slides over the smooth arched part 1424 from the strip body 1421 of the limiting claw 142 and then slides to the side of the bent part 1423. At this time, the secondary elastic retainer 143 is released to a certain extent, but it is still in a compressed state. Moreover, the secondary elastic retainer 143 is supported by its reverse elastic force. The limiting claw 142 rotates so that the protrusion 1422 on the limiting claw 142 engages with the aforementioned engaging groove 171; and because the end of the first guide post 1521 away from the second guide post 1522 passes through the first through hole opened on the secondary anchoring base 141 and is fixed with a guide limiting member 15211, the longitudinal area of ​​the guide limiting member 15211 is larger than the longitudinal area of ​​the first through hole, and the travel of the guide post 152 is greater than the depth of the first through hole; the third guide post 1523 and the guide tube 151 constitute the aforementioned clutch mechanism 15.Therefore, in this embodiment, during the anchor removal operation, the secondary elastic retainer 143 supports the rotation of the limiting claw 142 based on its reverse elastic force, so that the protrusion 1422 on the limiting claw 142 engages with the aforementioned locking groove 171. Subsequently, the primary power structure 11 continues to drive the anchor removal fixing ring 131, the anchor removal locking ring 132, and the anchor cable 18, which have formed a three-way linkage, to move together along the preset direction, so that the guide tube 151 continues to drive the guide post 152 to move along the preset direction. At this time, between the first guide post 1521 and the secondary anchor removal base 141, there are only the first guide post 1521, the second guide post 1522, and the third guide post 152 constituting the guide post 152. The column 1523 will move along the axial direction of the first through hole (the axial direction of the first through hole is parallel to the aforementioned preset direction) until the guide limiting member 15211 abuts against the secondary anchoring base 141 as the guide column 152 moves. This will also allow the first guide column 1521, the second guide column 1522, and the third guide column 1523 constituting the guide column 152 to drive the secondary anchoring base 141 to continue moving along the preset direction. Before the guide limiting member 15211 abuts against the secondary anchoring base 141, the limiting elastic member is in a compressed state to support the limiting clip and the limiting adapter hole, so that the secondary anchoring base 141 and the guide rail 122 remain linked, thus achieving... The secondary anchoring base 141 and the guide rail 122 are in a relatively stationary state. After the guide limiting member 15211 abuts against the secondary anchoring base 141, under the action of the guide limiting member 15211, the guide column 152 can drive the secondary anchoring base 141 to continue moving along the preset direction, thereby pushing the limiting clip between the secondary anchoring base 141 and the guide rail 122 to disengage from the limiting adapter hole, and the limiting elastic member is compressed in the opposite direction, thereby releasing the linkage between the secondary anchoring base 141 and the guide rail 122, so that the secondary anchoring base 141 and the guide rail 122 form a sliding connection; at this time, the secondary anchoring elastic member 123 in the compressed state is compressed. Upon release of force, under the elastic force of the secondary anchor release elastic element 123, the secondary anchor release elastic element 123 will drive the secondary anchor release base 141 to continue moving along the preset direction (at this time, the guide post 152 will also continue to drive the secondary anchor release base 141 to continue moving along the preset direction). At this time, because the protrusion 1422 of the limiting claw 142 is engaged with the locking groove 171 on the anchor plug 19, the limiting claw 142 is fixed on the secondary anchor release base 141. Therefore, as the secondary anchor release base 141 moves in the preset direction, the secondary anchor release base 141 will also drive the anchor plug 19 to continue moving in the preset direction, thereby driving the anchor plug 19 to disengage from the anchor ring 17, thus completing the anchor release operation.

[0151] Of course, during the reset operation of the automatic anchor release device, oil is injected into the reset oil chamber 113 through the reset oil injection hole 116. Because the piston 112 is fixed to the anchor seat 161, the cylinder 111 moves to the left. Since the cylinder 111 is fixed to the anchor release fixing ring 131, the cylinder 111 drives the anchor release fixing ring 131 to move to the left along the length of the anchor cable 18, thereby releasing the compression effect of the anchor release fixing ring 131 on the anchor release locking ring 132. The elastic reset spring 14411 releases its reverse elastic force, driving the spring guide sleeve 14412 to move to the left towards the anchor release locking ring 132. Furthermore, the contact surface between the spring guide sleeve 14412 and the anchor release locking ring 132 is set at an obtuse angle to the elastic force direction of the elastic reset element 1441. The protruding end of the third plug plate 1663 and the contact surface of the anchor release locking ring 132 are provided with a stop contact structure (the contact surface between the anchor opening plug component 16 and the anchor release locking ring 132 is provided with a stop contact structure). The second plug plate 1662 is arranged and fitted in the inclined cavity to ensure that the anchor release locking ring 132 has an outward tendency when subjected to the force of the spring 14411. Therefore, the anchor release locking ring 132 and the upper anchor opening plug component 16 slide together along the inclined cavity, thereby causing the end of the anchor clamp in the anchor release locking ring 132 that abuts against the anchor opening plug component 16 to arch up. That is, the two ends of the anchor clamp arch up, the inner diameter of the anchor release locking ring 132 increases, thereby releasing the compression of the anchor cable 18 by the anchor release locking ring 132; while the anchor release fixing ring During the leftward movement of 131, the anchoring ring 131 will also drive the guide tube 151 to move to the left. At this time, the guide post 152 (first guide post 1521, second guide post 1522 and third guide post 1523) is in a non-moving state until the limiting member 154 abuts against the side wall of the strip hole in the opposite direction of the preset direction. Then, the guide tube 151 will drive the guide post 152 to move to the left. The mating block 15212 on the first guide post 1521 slides from the bent part 1423 of the limiting claw 142 over the smooth arched part 1424 and slides to the side of the strip body 1421 (limiting claw 142). At this time, the secondary elastic retaining member 143 is compressed in the opposite direction, so that the limiting claw 142 rotates back to its original position around the above-mentioned rotating connection point. (The protrusion 1422 on the limiting claw 142 disengages from the locking groove 171 on the anchor plug 19); then, the guide post 152 continues to move in the reverse direction with the guide tube 151 until the guide limiting member 15211 on the guide post 152 disengages from the secondary anchoring base 141 (or, the guide limiting member 15211 disengages from the secondary anchoring base 141 and the second guide post 1522 on the guide post 152 abuts against the secondary anchoring base 141), so that the guide post 152 pushes the secondary anchoring base 141 to move in the reverse direction on the guide rail 122 until the limiting locking member between the secondary anchoring base 141 and the guide rail 122 slides back into the limiting adapter hole. At this time, the secondary anchoring elastic member 123 is in compression reset, thus completing the reset operation of the automatic anchoring device.

The first-stage anchor removal mechanism 13 moves with the cylinder 111 in the preset direction to drive the anchor cable 18 to move.

The guide post 152 can move back and forth along the length of the first through hole, and the travel distance of the guide post 152 is greater than the depth of the first through hole. Moreover, a guide limiting member 15211 is fixed at the end of the guide post 152 away from the guide tube 151, and the longitudinal area of ​​the guide limiting member 15211 is greater than the longitudinal area of ​​the first through hole.

[0174] The limiting structure 124 includes: a limiting hole 1241 formed on the inner wall of the second through hole 1412, a limiting elastic element, a limiting clip, and a limiting adapter hole; wherein, the limiting elastic element is disposed in the limiting hole 1241, and the length direction of the limiting elastic element is parallel to the length direction of the limiting hole 1241; the limiting clip is connected to the elastic end of the limiting elastic element; the limiting adapter hole is formed on the outer wall of the guide rail 122, and its shape and size are adapted to the groove and size of the limiting clip; when the limiting clip is engaged with the limiting adapter hole, the secondary anchoring elastic element 123 is in a compressed state, and the secondary anchoring base 141 and the guide rail 122 are in a relatively stationary state; when the limiting clip is disengaged from the limiting adapter hole, the secondary anchoring base 141 and the guide rail 122 form a sliding connection;

[0175] When the secondary anchor retraction mechanism 14 engages with the engagement groove 171, the secondary anchor retraction mechanism 14 continues to move with the cylinder 111 in a preset direction to release the limiting structure 124 in the secondary power structure. The secondary power structure drives the secondary anchor retraction mechanism 14 to continue moving along the preset direction, so that the anchor plug 19 is disengaged from the anchor ring 17 along the preset direction via the secondary anchor retraction mechanism 14, including:

[0176] When the protrusion 1422 of the limiting claw 142 engages with the locking groove 171, the guide post 152 continues to move with the guide tube 151 in a preset direction until the guide limiting member 15211 abuts against the secondary anchoring base 141, so as to link the guide post 152 and the secondary anchoring base 141 in a preset direction.

[0177] The secondary anchoring base 141 moves along the guide post 152 on the guide rail 122 in a preset direction, so that the limiting clip slides out of the limiting adapter hole to release the compressed state of the secondary anchoring elastic member 123.

[0178] The secondary anchor release elastic element 123 elastically releases to drive the secondary anchor release base 141 to continue moving along the preset direction on the guide rail 122, thereby causing the limiting claw 142 to drive the anchor plug 19 to continue moving in the preset direction, and the anchor plug 19 disengages from the anchor ring 17.

[0179] Preferably, the reset operation is performed when the automatic anchor release device is in the reset state.

[0180] Therefore, under the action of the cylinder 111, the anchor plug 19 can be moved out of the anchor ring 17 by the primary anchor removal mechanism 13 to expose the locking groove 171 opened on the anchor plug 19. Before this, the power transmission between the cylinder 111 and the secondary anchor removal mechanism 14 is disconnected based on the clutch mechanism 15. Therefore, under the action of the cylinder 111, the clutch mechanism moves with the anchor removal fixing ring 131 to connect the power transmission between the cylinder 111 and the secondary anchor removal mechanism 14. In this case, the cylinder drives the secondary anchor removal mechanism 14 to engage the locking groove 171 and drag it. The anchor plug 19 disengages from the anchor ring 17, thus automatically completing the anchor removal operation. This eliminates the need for manual removal of the anchor plug and cumbersome manual anchor removal procedures, simplifying the process. Furthermore, it reduces the need for multiple personnel, saving production costs, improving efficiency, and enhancing safety. The primary anchor removal mechanism 13 exposes the anchor plug 19 in the locking groove 171 on its outer wall, allowing the secondary anchor removal mechanism 14 to smoothly engage with this groove and complete the anchor removal operation. Moreover, it automatically completes the reset operation.

[0181] The terminology and implementation principle of the anchor removal method applied to the automatic anchor removal device in this embodiment can be referred to in any of the above embodiments for the automatic anchor removal device, and will not be repeated here.

[0183] S21: Oil is injected into the reset oil chamber 113 through the reset oil injection hole 116. The cylinder body 111 drives the anchor removal fixing ring 131 to move in the opposite direction of the preset direction. The gap between the anchor removal fixing ring 131 and the anchor removal locking ring 132 increases, so as to release the anchor removal locking ring 132 from pressing the anchor cable 18; thereby the anchor cable 18 can be pulled out.

[0184] The anchor-removing fixing ring 131 and the anchor-removing locking ring 132 are sleeved on the outer periphery of the anchor plug 19. The contact surfaces between the anchor-removing fixing ring 131 and the anchor-removing locking ring 132 are inclined. Moreover, the anchor-removing fixing ring 131 is fixed to the power output end of the cylinder 111.

[0185] S22: The guide tube 151 moves in the opposite direction of the preset direction along with the anchor-removing fixing ring 131 until the limiting member 154 abuts against the side wall of the strip hole in the opposite direction of the preset direction. At this point, the guide tube 151 and the guide post 152 move in conjunction in the opposite direction of the preset direction to realize the power transmission between the cylinder 111 and the secondary anchor-removing mechanism 14. Moreover, the guide tube 151 moves in the opposite direction of the preset direction along with the anchor-removing fixing ring 131 to push the end of the guide post 152 away from the guide tube 151 to drive the limiting claw 142 to rotate and reset in the opposite direction, while simultaneously enabling the secondary elastic retaining mechanism to rotate and reset. The holding member 143 is compressed; when the limiting claw 142 is reset, the guide tube 151 continues to move in the opposite direction of the preset direction with the anchoring fixing ring 131 to push the second guide post 1522 in the guide post 152 to abut against the secondary anchoring base 141, so that the first guide post 1521 and the secondary anchoring base 141 are linked in the opposite direction of the preset direction, and the secondary anchoring base 141 moves on the guide rail 122 in the opposite direction of the preset direction with the guide tube 151 so that the secondary anchoring elastic member 123 is compressed and reset, and the limiting clip moves into the limiting hole 1241.

[0186] Preferably, the automatic anchor release device further includes:

[0187] The anchor bolt assembly includes an elastic reset member 1441 and an anchor bolt opening plug component 16. The elastic reset member 1441 and the anchor bolt opening plug are respectively disposed at both ends of the anchor bolt locking ring 132 along the length of the anchor cable 18. The contact surfaces of the elastic reset member 1441 and the anchor bolt locking ring 132 are at an obtuse angle to the elastic force direction of the elastic reset member 1441. Alternatively, the contact surface between the anchor bolt opening plug component 16 and the anchor bolt locking ring 132 is provided with a stop contact structure, and the contact surfaces are at an acute angle to the elastic force direction of the elastic reset member 1441. Furthermore, the elastic reset member 1441 is disposed in the primary power structure 11, and the elastic force direction of the elastic reset member 1441 is parallel to the length direction of the anchor cable 18. The anchor bolt opening plug component 16 is fixed to the side wall of the anchor bolt seat 161 facing the anchor bolt locking ring 132.

[0188] In addition, an elastic return spring 14411 and a spring guide sleeve 14412 are provided at the large-diameter opening end of the anchor release locking ring 132 in the length direction of the anchor cable 18. Moreover, one end of the elastic return spring 14411 is fixed inside the spring guide sleeve 14412, and the end of the spring guide sleeve 14412 away from the elastic return spring 14411 abuts against the large-diameter opening end in the anchor release locking ring 132. The elastic force of the elastic return spring 14411 is parallel to the length direction of the anchor cable 18.

[0189] Furthermore, the contact surfaces of the spring guide sleeve 14412 and the anchor release locking ring 132 are set at an obtuse angle to the elastic force direction of the spring guide sleeve 14412; and the stop contact structure between the anchor opening plug component 16 and the anchor release locking ring 132 is provided with an inclined contact surface (i.e., the aforementioned plug inclined surface 168), which is set at an acute angle to the elastic force direction of the elastic reset member 1441;

[0190] When the cylinder 111 drives the anchor-removing fixing ring 131 to move in the opposite direction of a preset direction, the method further includes:

[0191] Under the driving action of the elastic return spring 14411, the spring guide sleeve 14412 presses the anchor release locking ring 132 in the opposite direction of the preset direction, so that the two ends of the anchor release locking ring 132 move with the contact surface of the spring guide sleeve 14412 and the stop contact structure between the anchor opening plug component 16, thereby causing the anchor release locking ring 132 to disengage from the anchor cable 18.

[0192] Specifically, the following settings can also be made for the anchor opening plug component 16 mentioned above:

[0193] according to Figure 4 As shown, the anchor opening plug component 16 includes: an anchor seat 161, an anchor retraction opening hole 162, an anchor retraction opening plug 163, an anchor retraction opening spring 1641, and a limiting seat 165.

[0194] The anchor seat 161 serves as the base of the automatic anchor release device, and the aforementioned primary power structure 11, secondary power structure, primary anchor release mechanism 13, and secondary anchor release mechanism 14 are all fixed to the anchor seat 161. Furthermore, the anchor seat 161 is located at the end of the anchor release locking ring 132 away from the elastic reset member 1441; moreover, the anchor release opening 162 is opened along the circumference of the anchor cable 18 at the end of the anchor seat 161 facing the anchor release locking ring 132; the shape and size of the anchor release opening 162 are adapted to the anchor release plug 163; the anchor release plug 163 is composed of multiple plug clips 166, which are arranged along the axial direction of the anchor cable 18 to form the anchor release plug 163, i.e., the shape and size of the anchor release opening 162 are adapted to the plug clips 166;

[0195] Furthermore, the anchor release opening 162 is composed of a first horizontal cavity and an inclined cavity, the length direction of which is set at an acute angle to the elastic force direction of the elastic reset member 1441; and each opening plug clip 166 includes a first plug plate 1661, a second plug plate 1662, and a third plug plate 1663, which are connected in sequence to make each opening plug clip 166 arranged in a "Z" shape; and the first plug plate 1661 is disposed in the first horizontal cavity, the second plug plate 1662 is arranged and fitted in the inclined cavity, the third plug plate 1663 is parallel to the axial direction of the anchor cable 18, and the end of the third plug plate 1663 away from the second plug plate 1662 extends out of the anchor release opening 162 and abuts against the anchor release locking ring 132. The end of the elastic reset member 1441; and, the contact surface between the protruding end of the third plug plate 1663 and the anchor release locking ring 132 is provided with a stop contact structure (the contact surface between the anchor opening plug component 16 and the anchor release locking ring 132 is provided with a stop contact structure), the stop contact structure includes: a plug vertical surface 167 and a plug inclined surface 168 provided at the protruding end of the third plug plate 1663 and a ring vertical surface and a ring inclined surface provided at the end of the anchor release locking ring 132 away from the elastic reset member 1441, the plug vertical surface 167 cooperates with the ring vertical surface, the plug inclined surface cooperates with the ring inclined surface, and the plug inclined surface 168 is set at an acute angle to the elastic force direction of the elastic reset member 1441, that is: when the anchor opening plug component 16 and the anchor release locking ring 132 are subjected to axial thrust, they have an outward movement tendency;

[0196] Furthermore, the anchor seat 161 is also provided with an opening plug limiting seat 165 at the anchor release opening hole 162. The opening plug limiting seat 165 extends toward the anchor cable 18 to cover the anchor release opening hole 162. Moreover, the aforementioned third plug plate 1663 is located between the opening plug limiting seat 165 and the anchor cable 18. The opening plug limiting seat 165 can restrict the displacement of the anchor release opening plug 163 along an axial direction perpendicular to the anchor cable 18, thereby preventing the anchor release opening plug 163 from falling off during the reset operation.

[0197] Each of the first plug plates 1661 has a groove on its outer wall, so that the portion of the anchor release plug 163 located in the first horizontal cavity has an outer ring groove. The anchor release spring 1641 is sleeved in the outer ring groove of the anchor release plug 163, and the free end of the anchor release spring 1641 is fixed to the inner wall of the first horizontal cavity; maintaining the minimum inner diameter of the multi-lobed anchor release plug 163 when it is not subjected to external force.

[0198] Therefore, when the compression of the anchor-removing fixing ring 131 on the anchor-removing locking ring 132 is released, the elastic return spring 14411 releases its reverse elastic force, driving the spring guide sleeve 14412 to drive the anchor-removing locking ring 132 to move in the reverse direction. Furthermore, because the protruding end of the third plug plate 1663 and the contact surface of the anchor-removing locking ring 132 are provided with a stop contact structure (the contact surface between the anchor opening plug component 16 and the anchor-removing locking ring 132 is provided with a stop contact structure), and the second plug plate 1662 is arranged and fitted in the inclined cavity, it ensures that the anchor-removing locking ring 132 has an outward tendency when subjected to the force of the spring 14411. Therefore, the anchor-removing locking ring 132 and the upper anchor opening plug component 16 slide together along the inclined cavity, thereby causing the anchor clamp in the anchor-removing locking ring 132 to abut against the... The end of the anchor opening plug component 16 is arched, which increases the inner diameter of the anchor release locking ring 132, thereby releasing the pressure of the anchor release locking ring 132 on the anchor cable 18. In this process, the structure of "the contact surface between the end of the spring guide sleeve 14412 away from the elastic return spring 14411 and the anchor release locking ring 132 is set at an obtuse angle to the elastic force direction of the elastic return member 1441 (the end of the spring guide sleeve 14412 away from the elastic return spring 14411 contacts the conical surface of the anchor release locking ring 132, and the outer contact is located on the anchor release locking ring 132)" can be combined to make both ends of the anchor clamp in the anchor release locking ring 132 arched, which increases the inner diameter of the anchor release locking ring 132, thereby releasing the pressure of the anchor release locking ring 132 on the anchor cable 18.
