Description

Technical Field

[0001] The present disclosure relates to the technical field of anchor support, and in particular, to an anchor support device. Background Art

[0002] Anchor support is a commonly used reinforcement method in the process of excavating mine tunnels or highway tunnels. It usually requires drilling a hole in the rock wall, sending the anchoring agent into the deep of the hole, and then using the anchor rod to evenly stir the anchoring agent deep in the hole, so that the anchor rod and the rock wall form a stable whole, thereby playing a stable support role.

[0003] In the prior art, the anchoring agent is mostly delivered manually. Since the borehole is generally selected above or obliquely above the tunnel, the anchoring agent is easy to fall off or get stuck in the borehole during delivery. Improper delivery operation will also cause the packaging surface of the anchoring agent to be damaged, making the overall support operation inefficient. After the anchoring agent is delivered deep into the borehole, the mixing operation using the anchor rod is also prone to uneven mixing or the anchoring agent after mixing fails to fill the borehole, which leads to unstable anchor support effect and certain safety hazards. Summary of the invention

[0004] The purpose of the present disclosure is to provide an anchor support device to at least partially solve the problems existing in the above-mentioned related technologies.

DETAILED DESCRIPTION

[0022] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0023] In the present disclosure, unless otherwise stated, directional words such as "upper" and "lower" generally refer to the upper and lower positions of the relevant components in actual use. Figure 1 The direction indicated by the arrow is the actual up and down direction of the anchor support device. "Inside and outside" refer to the inside and outside of the relative contours of the relevant components in actual use. "Middle" refers to the part of the relevant components located in the middle of the overall structure.

[0024] In addition, the terms "first", "second", etc. used in the present disclosure are intended to distinguish one element from another and do not have an order or importance.

[0025] The present disclosure discloses an anchor support device, referring to Figures 1 to 4The anchor support device has a plurality of sleeves connected in sequence, and the inner diameters of the plurality of sleeves are the same, wherein the plurality of sleeves may include a first sleeve 1, a second sleeve 2, and a third sleeve 3. The first sleeve 1 may be used to sleeve the anchor, and the anchor may be configured to be able to move axially inside the first sleeve 1, one end of the second sleeve 2 may be connected to the first sleeve 1, and is used to accommodate an anchor 4 inside, one end of the third sleeve 3 may be open, and the other end has a closed bottom surface, and the open end thereof may be connected to the other end of the second sleeve 2, and a stirring member 31 may be provided inside the third sleeve 3, and is used to stir the anchor 4 when in contact with the anchor 4.

[0026] In the above embodiment, the first sleeve 1, the second sleeve 2 and the third sleeve 3 can be connected end to end in sequence, and the first sleeve 1 is used to be threadedly connected to one end of the anchor rod, and the anchor support device can be positioned as a whole at the end of the anchor rod. When the two are threadedly connected, the anchor rod can be moved in or out of the first sleeve 1. The second sleeve 2 is connected to the first sleeve 1, and the anchor 4 can be accommodated in the second sleeve 2. Since the borehole used for anchoring in the tunnel is usually set at a high position, when the anchor rod sends the anchor 4 to the deep of the borehole at a high position, the second sleeve 2 can be used to position and lift the anchor 4 to prevent the anchor 4 from falling downward, and the second sleeve 2 can also protect the internal anchor 4 to prevent the anchor 4 from being damaged after being scraped against the wall of the borehole. At the same time, the third sleeve 3 is a sleeve structure with an open end, and a stirring piece 31 can be arranged inside it. When the anchor rod moves along the axial direction of the first sleeve 1, the anchor 4 can be gradually lifted toward the third sleeve 3 until the anchor 4 contacts the stirring piece 31 inside the third sleeve 3. The stirring piece 31 can cut the outer packaging surface of the anchor 4. At this time, the anchor 4 can be driven by the rotation of the anchor rod and can be continuously rotated and stirred along the circumferential direction with the stirring piece 31, so that the anchor 4 can be fully and evenly stirred and mixed in the third sleeve 3 and fully fill the depth of the borehole. After solidification, the anchor rod can be firmly fixed in the borehole, thereby realizing the anchoring effect of the anchor rod. The anchoring effect is firm and stable, and the operation is simple during anchoring. It can effectively cope with drilling holes of different angles and depths, and has good applicability.

[0027] It should be noted that the connection sequence of the above three sleeves and the anchor in the anchor support device can be freely combined according to actual needs. For example, the first sleeve 1, the second sleeve 2 and the third sleeve 3 can be first combined into an anchor support device, and then the end of the anchor support device with the first sleeve 1 can be screwed to the end of the anchor. When the amount of anchor 4 used varies, the first sleeve 1 can also be screwed to the end of the anchor, and then the second sleeve 2 can be connected to the first sleeve 1. At this time, any number of anchors 4 can be freely placed inside the second sleeve 2, and after the amount of anchor 4 used meets the demand, the open end of the third sleeve 3 can be connected to the second sleeve 2 to close the internal space of the anchor support device.

[0028] Through the above technical scheme, the anchor support device is composed of multiple casings connected in sequence. The first casing 1 among the multiple casings can be threadedly connected and positioned with the anchor. The second casing 2 can accommodate the anchor 4 so that the anchor can freely drive the anchor 4 to move, which is convenient for delivering the anchor into the deep of the borehole to prevent it from falling off. The third casing 3 is provided with a stirring member 31, which can pierce the anchor 4 and stir it when it comes into contact with the gradually lifted anchor 4, so that the anchor 4 can be evenly filled to the deep of the borehole, thereby improving the stability of the anchor in the borehole.

[0029] In some embodiments, reference Figures 1 to 3 The first casing 1 may include a threaded section 11 and a first interface section 12, wherein the threaded section 11 may be at least partially disposed on the inner wall of the first casing 1 for threaded connection with the anchor rod, the first interface section 12 may be disposed at one end of the first casing 1, and the second casing 2 may have a first connecting section 21 capable of extending into the first interface section 12 to connect the first casing 1 and the second casing 2. In this embodiment, the first interface section 12 may be disposed at one end of the first casing 1 close to the second casing 2, and the first connecting section 21 may be disposed at one end of the second casing 2 close to the first casing 1, which may extend into the first interface section 12 and be connected and fixed with the first interface section 12.

[0030] In other embodiments, reference Figures 1 to 3 The first interface section 12 of the first sleeve 1 can be configured to be recessed into the tube wall of the first sleeve 1 to form a step surface, so as to allow the first connecting section 21 to form a positioning fit between the recessed part of the tube wall of the first sleeve 1 and the first interface section 12, thereby fixing the first sleeve 1 and the second sleeve 2 together.

[0031] It should be noted that the step structure of the first interface section 12 can be provided on the inner wall of the first sleeve 1 (eg Figure 3 As shown), it can also be opened on the outer wall of the first sleeve 1. When the threaded section 11 is only partially arranged on the inner wall of the first sleeve 1, the inner wall of the first sleeve 1 can leave enough space at one end close to the second sleeve 2 for the first interface section 12 to form a step structure, thereby ensuring the structural integrity of the outer wall of the first sleeve 1.

[0032] For example, refer to Figures 1 to 3, the inner diameter of the first interface section 12 may be larger than the inner diameter of the main body of the first sleeve 1, the outer diameter of the first connection section 21 may be smaller than the outer diameter of the main body of the second sleeve 2, and the end of the first connection section 21 may abut against the step of the first interface section 12. In this embodiment, the step structure of the first interface section 12 is formed on the inner wall of the first sleeve 1, and the first connection section 21 may be inserted into the first interface section 12, and when abutting against the step of the first interface section 12, the first connection section 21 is positioned and connected with the inner wall of the first interface section 12 from the inside of the first sleeve 1 to the outside, thereby making the first sleeve 1 and the second sleeve 2 firmly connected.

[0033] For example, the threaded section 11 can be arranged in the middle of the first casing 1, and the first interface section 12 can be arranged on one side of the threaded section 11. The threaded section 11 is only arranged in the middle of the first casing 1, so that when connected with the anchor rod, the anchor rod first passes through the smooth section without threads on the inner wall of the first casing 1, which is conducive to the docking and positioning of the first casing 1 and the end of the anchor rod. In the case where the first casing 1, the second casing 2 and the third casing 3 are preferentially assembled into an anchor rod support device, the anchor rod support device has a certain length. If the end of the anchor rod is directly installed with the threaded section 11 of the first casing 1, there is a phenomenon of difficulty in docking. By arranging the threaded section 11 in the middle of the inner wall of the first casing 1, so that the side for docking the anchor rod is formed into a smooth section, the threaded section 11 is docked and positioned with the end of the anchor rod before the threaded section 11, which can effectively solve the above-mentioned problem of difficulty in direct docking between the anchor rod and the threaded section 11.

[0034] For example, refer to Figures 1 to 3 , the open end of the third sleeve 3 may be provided with a second interface section 32, and the other end of the second sleeve 2 may be provided with a second connection section 22, which may extend into the second interface section 32 to connect the second sleeve 2 and the third sleeve 3. In this embodiment, the other end of the second sleeve 2 opposite to the end provided with the first connection section 21 may be provided with a second connection section 22 connected to the third sleeve 3, and the second connection section 22 may extend into the second interface section 32 of the third sleeve 3 to connect the second sleeve 2 and the third sleeve 3. In the embodiment of the present disclosure, there is no specific restriction on the connection method between the second interface section 32 and the second connection section 22, and the two may also be fixedly connected by other connection methods such as screw connection, clamping connection or bonding, etc., to ensure that the second sleeve 2 and the third sleeve 3 are stable to each other after connection and are not easy to be separated from each other, and the transition of the connection between the two is smooth without obvious gaps.

[0035] For example, refer to Figures 1 to 3, the inner diameter of the second interface section 32 may be larger than the inner diameter of the body of the third sleeve 3, the outer diameter of the second connection section 22 may be smaller than the outer diameter of the body of the second sleeve 2, and the end of the first connection section 21 may abut against the step of the first interface section 12. In this embodiment, the connection method between the second interface section 32 and the second connection section 22 may also be the same as the connection method between the first interface section 12 and the first connection section 21. At this time, the second interface section 32 may be recessed in the inner wall of the third sleeve 3 to form a step structure, the inner diameter of the second interface section 32 may be larger than the inner diameter of the body of the third sleeve 3, and the outer diameter of the second connection section 22 may be smaller than the inner diameter of the body of the second sleeve 2, so that the end of the second connection section 22 can abut against the step of the second interface section 32, thereby forming a stable connection between the second sleeve 2 and the third sleeve 3.

[0036] In some embodiments, reference Figures 1 to 3 , the end of the second casing 2 connected to the first casing 1 may be provided with a partition 23, and the partition 23 is detachably connected to the inner wall of the second casing 2, wherein the partition 23 can be used to receive the anchor 4 when connected to the inner wall of the second casing 2. In this embodiment, the partition 23 provided in the second casing 2 can receive the anchor 4 upward along the height direction from the end close to the first casing 1, and at this time, the anchor 4 is inserted into the second casing 2 so that the anchor 4 can be accumulated above the partition 23, preventing the anchor 4 from falling off when the anchor rod is extended into the borehole.

[0037] At the same time, the partition 23 is detachably connected to the inner wall of the second sleeve 2. After the anchor rod gradually rotates upward and abuts against the partition 23, the edge of the partition 23 can be disconnected and separated from the inner wall of the second sleeve 2 by continuing to apply force. Here, a brittle connection can be formed at the edge where the partition 23 is connected to the inner wall of the second sleeve 2, and the thickness of the edge is less than the thickness of the partition 23. After the partition 23 is subjected to force, it can be broken preferentially from the edge to ensure the shape of the partition 23 itself is intact. Further, the partition 23 with a complete shape can be used as a pusher to push the anchor 4 upward until the anchor 4 is pushed to contact with the stirring member 31 and gradually stirred evenly. In this process, the partition 23 separates the anchor 4 from the end of the anchor rod, which can protect the packaging surface of the anchor 4 located at the bottom to prevent it from being damaged after direct contact with the high-speed rotating anchor rod, and make the content flow down along the inner wall of the second sleeve 2 in advance, hindering the rotation of the anchor rod.

[0038] In some embodiments, reference Figure 4The stirring member 31 may include a support rod 311 and a blade 312, wherein the support rod 311 may be arranged along the axial direction of the third sleeve 3 and may be fixedly connected to the bottom wall of the third sleeve 3, and the blade 312 may be wound around the support rod 311 to stir the anchor 4. In this embodiment, the bottom wall of the stirring member 31 is fixedly connected with the support rod 311 extending into the inside of the third sleeve 3, where the bottom wall is defined relative to the structure of the third sleeve 3 itself, and the blade 312 wound around the support rod 311 may stir the rotating anchor 4 after contacting the anchor 4. Since the anchor rod continues to rotate upward, the anchor 4 also follows the anchor rod to have an upward rotation trend. In this process, the blade 312 can stir the anchor 4 so that the anchor 4 is evenly mixed to ensure the anchoring effect of the anchor 4 on the anchor rod.

[0039] For example, refer to Figure 4 , a blade 313 may be provided at one end of the support rod 311, which is used to cut the package of the anchor 4 when it contacts the anchor 4, so that the contents can flow out and be mixed and stirred by the stirring member 31, and the blade 312 may be a spiral blade 312, and the edge of the blade 312 may be a sharp edge, so as to cut and stir the anchor 4. In this embodiment, the blade 313 may be made of a plastic material with a hardness less than that of the partition 23 and much less than that of the anchor rod, so that after the blade 313 cuts the anchor 4, the partition 23 can be pressed against the blade 313, which is conducive to the stirring of the anchor 4 into the interior of the third sleeve 3, and at the same time, the blade 313 and the anchor rod can be separated by the partition 23, so as not to damage the anchor rod, and avoid affecting the structural stability after anchoring after the anchor rod is damaged. At the same time, setting the blade 312 with a sharp edge can assist the support rod 311 to remove the packaging appearance of the anchor 4, accelerate the outflow speed and mixing efficiency of the anchor 4, and improve the stirring and mixing effect of the anchor 4. The spiral blade 312 should rotate in the same direction as the blade to achieve cutting and stirring. The blade 312 can also adopt other shapes that are conducive to cutting and stirring the anchor 4, such as paddle, anchor or turbine, etc., which can also provide better cutting and stirring effects on the anchor 4.

[0040] In some embodiments, reference Figure 4 The circumferential side wall of the third sleeve 3 may be uniformly provided with a plurality of through grooves 33 along the circumferential direction, and the plurality of through grooves 33 may extend along the axial direction of the third sleeve 3. The stirred anchor 4 may overflow out of the device through the through grooves 33 and fill into the borehole, ensuring that the device and the borehole are filled with the anchor 4 without any gaps, and the through grooves 33 are only provided in the third sleeve 3, so that after the anchor 4 overflows out of the device, it is first filled into the bottom of the borehole, and then gradually filled from the bottom of the hole to the hole mouth, and this process can avoid the mixing of bubbles into the anchor, so as to ensure the anchoring effect of the anchor 4 on the anchor rod after solidification.

[0041] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0042] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction.
