[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] like Figure 1 As shown, the utility model provides a disassembly device, which includes a support rod 10, a clamping assembly 20 and an impact part 30. The support rod 10 has a first section 11 and a second section 12 arranged in sequence, and a limit block 13 is provided at one end of the first section 11 away from the second section 12. The clamping assembly 20 is arranged on the second section 12, and the clamping assembly 20 includes a driving member 21 and a clamping part 22 arranged in sequence. The driving member 21 is drivingly connected to the clamping part 22, and the driving member 21 drives the clamping part 22 to clamp or release the pin. The impact part 30 is slidably mounted on the first section 11, and the impact part 30 can impact the limit block 13 to pull out the pin by inertia force.

[0042] Applying the technical solution of the present invention, the disassembly device includes a support rod 10, a clamping assembly 20 and a striking part 30. The clamping assembly 20 is arranged on the support rod 10 and is used to clamp the pin. The striking part 30 is sleeved on the support rod 10, and strikes the limit block 13 on the first section 11 of the support rod 10. The inertia force of the striking part 30 is combined with the clamping action of the clamping assembly 20 to smoothly pull out the pin. The support rod 10 is divided into two parts: a first section 11 and a second section 12. The striking part 30 is sleeved on the first section 11 to ensure that the striking part 30 can easily move freely along the axial direction of the support rod 10 in the first section 11. The clamping assembly 20 is provided on the second section 12, wherein the clamping assembly 20 includes a driving member 21 and a clamping part 22, and the driving member 21 drives the clamping part 22 to clamp or release the pin. During operation, the driver 21 drives the clamping portion 22 to clamp the pin. At this time, the impact portion 30 begins to move axially along the first section 11, striking the stopper 13 on the support rod 10, generating an inertial force away from the second section 12, thereby pulling the pin out. After the pin is pulled out, the driver 21 drives the clamping assembly 20 to release the pin, placing it in a storage area.

[0043] Specifically, the support rod 10 is designed to have two parts, namely a first section 11 and a second section 12. These two sections can be fixed together by welding or threading to form a whole. The first section 11 is provided with a stopper 13 at the end away from the second section 12. The impact part 30 hits the stopper 13 on the first section 11 to prevent excessive displacement of the impact part 30. At the same time, it can flexibly reciprocate along the first section 11 to provide inertia force for the pin to be pulled out. This can effectively help the pin to be pulled out, especially when the pin is corroded or stuck.

[0044] Specifically, the impact part 30 can be slidably mounted on the first section 11 of the support rod 10. The impact part 30 can be a swing hammer that swings up and down to impact the limit block 13, and utilizes the inertia force generated by the swing hammer to pull the pin out of the hydraulic support.

[0045] like Figure 3 As shown, the clamping portion 22 includes a plurality of jaws 221, the extension direction of the jaws 221 is the same as the extension direction of the support rod 10, and the plurality of jaws 221 are distributed in a ring around the outer periphery of the second section 12, and the middle part of the jaws 221 is rotatably connected to the second section 12, and the jaws 221 have a driving section 2211 and a clamping section 2212 arranged in sequence, and the driving section 2211 is arranged close to the first section 11, and the driving member 21 is driven and connected to the driving section 2211, and the clamping section 2212 is used to clamp the pin shaft, and the driving member 21 drives the plurality of clamping sections 2212 to approach each other through the driving section 2211 to clamp the pin shaft.

[0046] In this embodiment, the clamping portion 22 includes multiple jaws 221. The jaws 221 extend in the same direction as the support rod 10 and are distributed in a ring around the outer circumference of the second section 12 of the support rod 10, forming a clamping structure around the pin, ensuring that the pin can be securely clamped from multiple directions. The middle portion of the jaws 221 is rotatably connected to the second section 12 of the support rod 10 via a pin or hinge, allowing the jaws 221 to rotate relative to the pin, thereby clamping or releasing the pin. Each jaw 221 has a sequentially arranged driving section 2211 and a clamping section 2212. The driving section 2211 is located near the first section 11 of the support rod 10 and is drivingly connected to the driver 21. The design of the driving section 2211 allows it to directly respond to the movement of the driver 21, thereby driving the entire jaw 221. The clamping section 2212, located at the end away from the driving section 2211, is responsible for actually clamping the pin. When the driving member 21 drives the multiple driving segments 2211 to move, the clamping segments 2212 of the multiple clamping jaws 221 will approach each other, thereby forming a combined force to firmly clamp the pin shaft.

[0047] Specifically, the outer surface of the clamping section 2212 of each clamping jaw 221 can be covered with a soft material, such as a rubber pad, which not only protects the pin shaft, but also increases friction and improves the clamping effect, ensuring that the clamping jaw 221 can accurately and forcefully grasp the pin shaft while avoiding damage to it.

[0048] like Figure 1 As shown, the driving member 21 is sleeved on the outer periphery of the second section 12. The driving member 21 can move relative to the second section 12 along the extension direction of the support rod 10 to approach or move away from the multiple driving sections 2211. The driving member 21 is squeezed and matched with the multiple driving sections 2211 to drive the multiple clamping sections 2212 to clamp the pins. In this embodiment, the driving member 21 is sleeved on the outer periphery of the second section 12 of the support rod 10. The driving member 21 has an internal thread that can match the external thread on the second section 12 of the support rod 10, thereby allowing the driving member 21 to move axially relative to the support rod 10. The movement of the driving member 21 on the second section 12 is achieved by rotating the driving member 21. The direction of rotation can determine whether the driving member 21 approaches or moves away from the multiple driving sections 2211, thereby affecting whether the clamping assembly 20 is clamped or released.

[0049] like Figure 1 and Figure 4As shown, the first section 11 is a polished rod structure, the second section 12 is a screw structure, and the driving member 21 includes a sleeve 211 and a rotary disk 212. The sleeve 211 is sleeved around the outer periphery of the second section 12 and is threadedly connected to the second section 12. The sleeve 211 is press-fitted with multiple driving sections 2211 to drive the multiple clamping jaws 221 to rotate. The rotary disk 212 is sleeved on the end of the sleeve 211 away from the clamping portion 22, and drives the sleeve 211 to rotate on the second section 12.

[0050] Specifically, the first section 11 of the support rod 10 is designed as a polished rod structure with a smooth surface and no threads, allowing the impact portion 30, such as a hammer, to slide freely along the surface without being hindered by the threads. The second section 12 is a screw structure with threads for threaded connection with the sleeve 211 in the driver 21.

[0051] In this embodiment, the driving member 21 includes a sleeve 211 and a turntable 212. The sleeve 211 is sleeved on the outer periphery of the second section 12 of the support rod 10, and its inner wall is provided with an internal thread that matches the thread of the second section 12. When the sleeve 211 rotates relative to the second section 12 of the support rod 10, the sleeve 211 moves axially along the support rod 10, thereby changing its relative position with the multiple driving sections 2211. The sleeve 211 and the driving sections 2211 are connected by an extrusion fit. When the sleeve 211 moves close to the driving section 2211, it generates an extrusion force on the driving section 2211. This extrusion force is transmitted to the middle part of the multiple clamping jaws 221, driving the clamping jaws 221 to rotate around the pin, so that the clamping sections 2212 of the clamping jaws 221 approach each other, thereby clamping the pin. Conversely, when the sleeve 211 moves away from the driving section 2211, the restoring force of the spring or other elastic element causes the driving section 2211 to return the clamping jaws 221 to their original positions, releasing the pin. The rotary disk 212 is mounted on the end of the sleeve 211 away from the clamping portion 22. The rotary disk 212 and the sleeve 211 can be relatively fixed via a keyway connection, a pin connection, or other means, ensuring that the rotation of the rotary disk 212 directly drives the sleeve 211 to rotate on the second section 12 of the support rod 10.

[0052] Specifically, the outer edge of the turntable 212 can be equipped with anti-slip grooves or a handle to facilitate the operator's application of rotational force. During operation, the operator rotates the turntable 212, driving the sleeve 211 to move axially along the second section 12 of the support rod 10, thereby controlling the clamping and release actions of the multiple clamping jaws 221, thereby achieving rapid disassembly of the hydraulic support pin.

[0053] like Figure 4As shown, the clamping portion 22 also includes a fixing seat 222, which is sleeved on the end of the second section 12 and located on the side of the sleeve 211 away from the first section 11. The fixing seat 222 is threadedly connected to the second section 12, and there is a gap between the fixing seat 222 and the sleeve 211. The clamping jaw 221 is hingedly connected to the fixing seat 222.

[0054] In this embodiment, the clamping portion 22 further includes a fixing seat 222, which is sleeved on the end of the second section 12 of the support rod 10 and is located on the side of the sleeve 211 away from the first section 11. The main function of the fixing seat 222 is to provide a stable installation and connection point for the clamping jaw 221, thereby ensuring the stability of the clamping jaw 221 during operation. The fixing seat 222 is connected to the second section 12 of the support rod 10 by a threaded connection, and its position can be adjusted along the axial direction of the support rod 10. This not only facilitates the installation and removal of the clamping portion 22, but also allows the operator to adjust the optimal working position of the clamping portion 22 according to the size and position of the pin to adapt to different working environments and needs.

[0055] like Figure 3 As shown, the clamping portion 22 also includes a fixing sleeve 223 and a plurality of elastic members 224. The extension direction of the fixing sleeve 223 is the same as the extension direction of the support rod 10. The clamping section 2212 is annularly arranged on the outer periphery of the fixing sleeve 223. The plurality of elastic members 224 are arranged in a one-to-one correspondence with the plurality of clamping sections 2212. One end of the elastic member 224 is connected to the fixing sleeve 223, and the other end of the elastic member 224 is connected to the corresponding clamping section 2212. The elastic member 224 can provide a driving force for the plurality of clamping sections 2212 to move away from each other.

[0056] In this embodiment, the clamping portion 22 further includes a fixing sleeve 223 and a plurality of elastic members 224. The fixing sleeve 223 extends in the same direction as the support rod 10, i.e., is distributed along the axis of the support rod 10. The fixing sleeve 223 is disposed between the driving member 21 and the plurality of clamping jaws 221. As a supporting structure for the clamping jaws 221, it can be secured to the second section 12 of the support rod 10 via welding, threaded connection, or other means to ensure that relative displacement does not occur during operation. The outer periphery of the fixing sleeve 223 is designed to be annular, and the clamping sections 2212 of the plurality of clamping jaws 221 are distributed on the outer periphery of the fixing sleeve 223. This allows the clamping jaws 221 to evenly clamp the pin from all directions, improving clamping stability and efficiency. The plurality of elastic members 224 are arranged in a one-to-one correspondence with the plurality of clamping sections 2212, with one end of each elastic member 224 connected to the fixing sleeve 223 and the other end connected to the corresponding clamping section 2212. The elastic member 224 provides a driving force for the clamping segments 2212 to move away from each other, so that when no external force is applied, the multiple clamping segments 2212 are naturally separated, facilitating the insertion and positioning of the pin. When the driver 21 transmits a compressive force to the clamping segments 2212 via the driver segments 2211, the clamping segments 2212 overcome the elastic force of the elastic member 224 and move closer together, firmly clamping the pin. This allows the operator to easily control the clamping and release of the clamping portion 22 by rotating the driver 21 without the need for additional operating steps, further enhancing the adaptability and clamping force of the clamping portion 22 on the pin.

[0057] Specifically, the elastic member 224 can be a compression spring or a tension spring, etc., which can more flexibly adapt to pins of different specifications and can automatically adjust the clamping force, thereby ensuring that the pin is firmly clamped and avoiding damage to the pin due to excessive clamping force.

[0058] Furthermore, the outer wall of the sleeve 211 tilts from the turntable 212 toward the support rod 10 in a direction approaching the clamping portion 22, and the distance between the driving section 2211 and the outer wall of the sleeve 211 gradually increases in a direction toward the fixed seat 222. In this embodiment, the sleeve 211 portion of the clamping assembly 20 has a specially designed outer wall that gradually tilts from the turntable 212 toward the support rod 10 in a direction toward the clamping portion 22. In a direction toward the driving member 21, the distance between the outer wall of the sleeve 211 and the driving section 2211 gradually increases. This means that the outer wall of the sleeve 211 is closer to the driving section 2211 at the end closer to the driving member 21, while the distance between the outer wall and the driving section 2211 is increased at the end farther away from the driving member 21 and closer to the clamping portion 22, thereby utilizing the mechanical advantage of the lead screw principle and the inclined surface.

[0059] When the operator rotates the driver 21, the driver 21 moves axially along the support rod 10. As the distance between the outer wall of the sleeve 211 and the driver section 2211 gradually increases toward the rotating member, when the driver 21 approaches, it squeezes the outer wall of the sleeve 211, causing the sleeve 211 to move inward. This displacement is transmitted to the clamping section 2212, which drives the clamping section 2212 of the clamping portion 22 toward the center of the pin, thereby firmly clamping the pin. When the driver 21 moves away, the sleeve 211 returns to its initial position under the action of a spring or other elastic element, and the clamping portion 22 releases the pin, facilitating its removal or replacement.

[0060] Furthermore, the clamping section 2212 comprises a third section 01 and a fourth section 02, which are arranged sequentially. The distance between the third section 01 and the sleeve 211 gradually increases as it moves away from the driving section 2211, while the distance between the fourth section 02 and the sleeve 211 gradually decreases as it moves away from the driving section 2211. In this embodiment, the clamping section 2212 is subdivided into two parts: the third section 01 and the fourth section 02. This further optimizes the structure of the clamping section 2212, enhancing its adaptability and clamping stability for pins of varying specifications. The distance between the third section 01 and the sleeve 211 gradually increases as it moves away from the driving section 2211, while the distance between the fourth section 02 and the sleeve 211 gradually decreases as it moves away from the driving section 2211. This allows the clamping section 2212 to form a V-shaped or wedge-shaped structure, thereby better adapting to the pin's shape when clamping it, improving the tightness and reliability of the clamping.

[0061] like Figure 2 As shown, a stop block 14 is also provided on the second section 12, and the stop block 14 is threadedly connected to the second section 12. The stop block 14 is located at one end of the driving member 21 close to the first section 11. In this embodiment, a stop block 14 is also provided on the second section 12 of the support rod 10. The stop block 14 is threadedly connected to the second section 12, which not only provides stability for the stop block 14, but also allows the operator to adjust the position of the stop block 14 according to actual conditions to adapt to the disassembly requirements of pins of different lengths or positions. The stop block 14 is located at one end of the driving member 21 close to the first section 11, that is, between the driving member 21 and the first section 11. By rotating the stop block 14 so that it moves axially along the thread of the second section 12 of the support rod 10, the effective movement range of the driving member 21 on the support rod 10 can be adjusted. When the stop block 14 moves to a position close to the driving member 21, it will limit the further movement of the impact part 30, prevent excessive squeezing of the driving section 2211, avoid unnecessary damage to the clamping jaws 221 or the pin, and improve the reliability and safety of the device.

[0062] Specifically, the stopper 14 can be cylindrical or other shaped. The threaded connection portion between the stopper 14 and the second section 12 of the support rod 10 is typically of a certain length to provide sufficient thread contact area and ensure a stable connection. The outer wall of the stopper 14 can be designed with anti-slip grooves to facilitate manual rotation and position adjustment. Furthermore, the material selection for the stopper 14 should consider its strength and wear resistance to ensure durability over long-term use.

[0063] Furthermore, the impact part 30 includes a body 31 and a pull rod 32, the body 31 is movably mounted on the outer periphery of the first section 11, and one end of the pull rod 32 is hinged to the body 31. In this embodiment, the impact part 30 includes a body 31 and a pull rod 32, which assists the pin extraction process by providing a controllable impact mechanism. The body 31 is a roughly cylindrical structure, and its inner diameter is slightly larger than the outer diameter of the first section 11 of the support rod 10, so that the body 31 can be mounted on the outer periphery of the first section 11 and slide freely along its axial direction, which can ensure that the body 31 can be moved to the appropriate position of the pin as needed during use, thereby enhancing its impact effect on the pin. One end of the pull rod 32 is connected to the body 31 in an articulated manner, that is, connected by a pin or hinge, so that the pull rod 32 can rotate freely relative to the body 31. The other end of the pull rod 32 can be designed as a free end, or connected to the operator's handheld part, so that the operator can control its movement trajectory and impact force. The length and material selection of the pull rod 32 need to be optimized according to the pin extraction requirements and the mass of the main body 31 to ensure that when the impact force is applied, sufficient inertial force can be generated to help loosen and pull out the pin, while avoiding damage to the main body 31, the pin or other parts of the device. It is not restricted by the working space and can be flexibly carried, which reduces the labor intensity of employees.

[0064] This device allows for rapid pull-out and removal of pins, replacing the manual process of disassembling hydraulic support pins using hammers, crowbars, etc., saving labor and avoiding safety hazards. Furthermore, the device prevents the pins from being damaged during disassembly, allowing for reuse. Furthermore, it can accommodate the disassembly of pins of different models, greatly improving the efficiency of component disassembly.

Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0068] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0069] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this utility model.

[0070] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
