Description

Technical Field

[0001] This application relates to the field of locomotive auxiliary equipment technology, and in particular to a disassembly device. Background Technology

[0002] In electric locomotives, the running gear's drive unit connects the frame and the traction motor via rubber joints at both ends of the motor boom. The motor boom not only bears the weight of the motor but also the torque generated by its forward and reverse rotation, making it a critical component of the electric locomotive's suspension system. During routine maintenance, the rubber joints at both ends of the motor boom need to be replaced.

[0003] In the existing technology, the disassembly of the rubber joint of the motor boom is generally carried out by using simple tools in conjunction with a hydraulic press. During the disassembly process, eccentric force is prone to occur, which can lead to the problem of tearing and damage to the inner holes at both ends of the motor boom. Summary of the Invention

[0004] In view of the above problems, this application provides a disassembly device to solve the problem in the above-mentioned related technologies that eccentric force is easily generated during the disassembly of the rubber joint of the motor rod, resulting in the inner hole of both ends of the motor rod being strained and damaged.

[0005] This application provides a disassembly device for disassembling the rubber joint of a locomotive traction motor boom. The motor boom includes a mounting hole for mounting the rubber joint. The disassembly device includes: a support base for placing and supporting the motor boom, such that the central axis of the mounting hole is arranged vertically; and a disassembly component, separately disposed from the support base. The disassembly component includes a driving part, a positioning part, and a pushing part arranged sequentially along the axial direction. The driving part receives external driving force. The outer contour of the pushing part matches the shape of the mounting hole. The pushing part has a cavity structure for accommodating at least a portion of the structure of the rubber joint. Under the action of external driving force, the pushing part can pass through the mounting hole and push the rubber joint, causing the rubber joint to exit from the mounting hole. The positioning part abuts against the end face of the motor boom during the disassembly process to limit the displacement of the disassembly component relative to the motor boom in the vertical direction.

[0006] The disassembly device in this embodiment places and supports the motor rod through a support base, so that the mounting holes of the motor rod are arranged in a vertical direction. In this way, the motor rod can maintain a relatively stable posture during disassembly, which helps to reduce uneven force caused by positional displacement.

[0007] By setting up a removable part that is separate from the support base, the removable part can be replaced individually after it wears out, reducing maintenance costs. At the same time, the removable part can be replaced with a matching one according to the different specifications of the motor boom, improving the versatility and flexibility of the device. In addition, the separate structure makes the overall weight of the device lighter, making it easier for the operator to pick up and operate.

[0008] By incorporating a positioning part and a pushing part into the unloading component, the positioning part abuts against the end face of the motor boom during unloading, thus limiting the vertical displacement of the unloading component relative to the motor boom. The pushing part has a cavity structure that matches the shape of the mounting hole, accommodating part of the rubber joint structure. This ensures a more snug fit when the pushing part passes through the mounting hole, facilitating a more even distribution of external driving force to the rubber joint. This reduces the risk of damage to the inner wall of the motor boom mounting hole due to eccentric force, thereby reducing the cost of boom scrapping and maintenance.

[0009] In some embodiments, the shape of the cavity structure matches the end shape of the rubber joint spindle, and the end of the cavity structure away from the drive part is an open structure.

[0010] In some embodiments, the outer diameter of the pushing part is smaller than the inner diameter of the mounting hole of the motor rod.

[0011] In some embodiments, the outer diameter of the driving part is smaller than the outer diameter of the pushing part, and a transition part is formed between the driving part and the pushing part; wherein the outer diameter of the transition part gradually increases from the end near the driving part to the end near the pushing part.

[0012] In some embodiments, the positioning part is a rod-shaped structure, one end of which is located outside the unloading member, and the other end extends radially along the unloading member to outside the outer contour of the pushing part; wherein the radially extending dimension of the rod-shaped structure is greater than half the inner diameter of the motor rod mounting hole, so that the lower surface of the rod-shaped structure can abut against the upper end face of the motor rod during unloading, thereby limiting the axial displacement of the motor rod.

[0013] In some embodiments, the number of positioning parts is multiple; wherein the multiple positioning parts are evenly distributed along the circumference of the unloading member.

[0014] In some embodiments, the axial distance between the surface of the positioning portion facing the pushing portion and the end face of the pushing portion away from the driving portion is equal to or greater than the axial installation depth of the rubber joint in the mounting hole.

[0015] In some embodiments, the ejector is provided with a perforated structure; wherein the perforated structure penetrates the ejector radially; the perforated structure is used for inserting an auxiliary positioning rod to rotate and adjust the position of the ejector.

[0016] In some embodiments, the number of perforated structures is two, and the two perforated structures are arranged at circumferential intervals along the unloading member.

[0017] In some embodiments, the support base is provided with a through hole structure; the inner diameter of the through hole structure is larger than the inner diameter of the motor rod mounting hole, and the axial dimension of the through hole structure is greater than or equal to the axial dimension of the mounting hole; the through hole structure is used to accommodate the rubber joint that is removed from the motor rod.

[0031] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] In the operation and maintenance of electric locomotives, the drive unit is one of the core components. The drive unit of the running gear connects the frame and the traction motor via rubber joints at both ends of the motor boom. The motor boom not only bears the weight of the motor but also the torque generated by the motor's forward and reverse rotation, making it a critical component of the electric locomotive's suspension system. During routine maintenance, the rubber joints at both ends of the motor boom are prone to aging and wear due to long-term stress, requiring periodic replacement to ensure the stability and safety of the electric locomotive's operation. However, the current method of disassembling the rubber joints typically uses simple tools with a hydraulic press, resulting in poor stability. The motor boom is prone to eccentric stress and positional displacement, leading not only to jamming of the rubber joints and difficulty in disassembly but also to deformation and scratches on the motor boom, further increasing the cost of parts replacement and repair. In addition, the current method is prone to component slippage, causing personnel injury, and the cumbersome operation process restricts overall maintenance efficiency, making it difficult to meet the requirements of high-efficiency maintenance of electric locomotives.

[0033] In view of the above problems, this application provides a disassembly device that places and supports the motor rod by setting a support base, so that the mounting hole of the motor rod is arranged in a vertical direction to maintain the stable posture of the motor rod. At the same time, a disassembly part is provided, which includes a positioning part and a pushing part and is separately matched with the support base. The positioning part abuts against the end face of the motor rod during disassembly, which can limit the displacement of the disassembly part relative to the motor rod in the vertical direction. The outer contour of the pushing part matches the shape of the mounting hole and has a cavity structure that can accommodate a portion of the rubber joint structure, so that the external driving force is transmitted to the rubber joint more evenly, thereby reducing the rubber joint jamming phenomenon and reducing the risk of damage to the inner wall of the mounting hole.

[0034] The disassembly device in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0035] Figure 1 This is a schematic diagram of the disassembly device according to an embodiment of this application. Figure 2 This is a schematic diagram of the structure of the motor lifting rod of the disassembly device according to an embodiment of this application. Figure 3 This is a schematic diagram of the support base of the disassembly device according to an embodiment of this application. Figure 4 This is a schematic diagram of the structure of the base plate of the disassembly device according to an embodiment of this application. Figure 5 This is a schematic diagram of the structure of the disassembly device for removing parts according to an embodiment of this application.

[0036] This application provides a disassembly device 100, which can be used to disassemble the rubber joint 201 of the locomotive traction motor boom 200. (In conjunction with...) Figure 1 and Figure 2 As shown, the motor hanger 200 may include mounting holes 202 for mounting rubber joints 201. Each motor hanger 200 may include two mounting holes 202, and each mounting hole 202 may contain one rubber joint 201. The structure of the motor hanger 200 in this embodiment may be the same as that of the motor hanger 200 in related technologies, and is not further limited here.

[0037] See also Figure 1 As shown, the disassembly device 100 may include a support base 1 and a retraction component 2. The support base 1 is used to place and support the motor rod 200 so that the central axis of the mounting hole 202 of the motor rod 200 is arranged in a vertical direction. In this embodiment, the vertical direction is represented by the z-direction in the figure. The retraction component 2 is used to push the rubber joint 201 out of the mounting hole 202 of the motor rod 200 under the action of an external driving force.

[0038] See Figure 1 As shown in this embodiment, to ensure that both mounting holes 202 of the motor rod 200 are on the same horizontal plane, reduce the risk of scratches or damage to the inner walls of the mounting holes 202, and avoid jamming during disassembly, the support base 1 can be placed horizontally. Thus, when the motor rod 200 is placed on the support base 1, the two mounting holes 202 of the motor rod 200 can be on the same horizontal plane, ensuring that the central axis of the mounting holes 202 of the motor rod 200 is parallel to the vertical direction (z-direction).

[0039] In some embodiments, combined with Figure 1 and Figure 3As shown, the support base 1 includes a base plate 12 and a support plate 13. The support plate 13 includes a support surface 131, which can be used to support the motor lifting rod 200. The base plate 12 can bear the force exerted by the motor lifting rod 200, the disassembly component 2, and the external driving force during disassembly, and transmit this force to the base 300 in contact with the base plate 12, increasing the contact area between the support base 1 and the base 300, so that the support base 1 remains stable under stress and does not shift. The base 300 can be the ground or an operating platform, etc., and the type of base 300 can be selected as needed. No further limitations are made in this embodiment.

[0040] In some embodiments, see Figure 3 and Figure 4 As shown, the base plate 12 and the support plate 13 can be fixedly connected. For example, the base plate 12 can be welded to the support plate 13 or integrally formed to improve the structural strength of the support base 1.

[0041] Of course, in other embodiments, the base plate 12 and the support plate 13 can also be detachably connected. For example, the base plate 12 and the support plate 13 can be snapped together, and a groove 121 can be provided on the end face where the base plate 12 and the support plate 13 connect. The groove 121 has a certain depth, which can be set as needed. The groove 121 can accommodate the support surface 131 in the vertical direction (z-direction) away from the motor boom 200. The side flanges of the groove 121 can limit the radial offset of the support plate 13. After disassembly, the base plate 12 and the support plate 13 can be separated for easy transportation. This reduces the weight of the support base 1 for workers to handle and facilitates the replacement of damaged bases or support plates 13, thereby improving replacement efficiency and reducing replacement costs. In this embodiment, the connection method of the base plate 12 and the support plate 13 is not further limited.

[0042] In some embodiments, see continue to see Figure 3 As shown, there can be one base plate 12, which has two mounting positions for mounting a support plate 13. The support plate 13 is fixed to the mounting positions. It can be understood that the distance between the two mounting positions corresponds to the distance between the two mounting holes 202 on the motor rod 200. Thus, when the support plate 13 is positioned, it can correspond to the two mounting holes 202 on the motor rod 200, ensuring the stability of the motor rod 200.

[0043] For example, the base plate 12 can be integrally formed or welded according to the size of the motor rod 200, which can simplify the structure of the base plate 12 and enhance the structural stability.

[0044] Of course, in some other embodiments, combined with Figure 1 and Figure 3 As shown, there can be multiple base plates 12. For example, there can be two base plates 12. One base plate 12 can be used to install one support plate 13. When the motor rod 200 needs to be supported, the two base plates 12 can be placed at positions corresponding to the two mounting holes 202 of the motor rod 200, and then the corresponding support plates 13 can be installed to form a support base 1.

[0045] This allows the positions of the two base plates 12 to be adjusted according to the different sizes of the motor hanger 200, so as to match motor hangers 200 of different sizes, thereby improving the versatility and ease of use of the support base 1.

[0046] In this embodiment, the structure and quantity of the base plate 12 can be selected as needed, and no further restrictions are imposed here.

[0047] In some embodiments, the bottom of the base plate 12 is provided with a movable component. For example, the bottom of the base plate 12 is provided with a plurality of rollers. The rollers can roll relative to the top plate, so that the base plate 12 can be moved on the ground by the rollers, and the user can adjust the position of the base plate 12 by pushing it, which helps to reduce the physical exertion of workers in adjusting the position of the base plate 12 and improves the efficiency of assembly and disassembly operations.

[0048] Of course, in other embodiments, the moving part can also be other structures, such as a slide rail. In this application embodiment, the specific form of the moving part of the base plate 12 is not limited, and can be selected according to the operation situation.

[0049] In some possible embodiments, the base plate 12 may also include a locking component (not shown) for locking the base plate 12 when it is moved to a position that meets the requirements of the disassembly operation, so as to reduce the possibility that the base plate 12 may shift relative to the base 300 under stress.

[0050] For example, the locking component can be a locking screw, and the base 300 is provided with a screw hole that matches the locking screw. When the base plate 12 moves into place, the locking screw is adjusted to engage with the screw hole, thereby fastening the base plate 12 to the base 300.

[0051] In this way, during the unloading process, the base plate 12 remains stable in the axial or radial direction relative to the base 300, which helps maintain the stable posture of the motor rod mounting hole 202, thereby reducing the risk of deformation or damage to the inner wall of the mounting hole 202 due to the offset of the base plate 12. The specific type of locking component can be selected as needed, and this embodiment does not impose further limitations.

[0052] In some embodiments, combined with Figure 2and Figure 3 As shown, the support base 1 is provided with a through-hole structure 11. The inner diameter of the through-hole structure 11 is larger than the inner diameter of the mounting hole 202 of the motor rod 200, and the axial dimension of the through-hole structure 11 is greater than or equal to the axial dimension of the mounting hole 202. The through-hole structure 11 is used to accommodate the rubber joint 201 that is removable from the motor rod 200. It should be noted that the axial direction of the through-hole structure 11 is parallel to the vertical direction (z-direction).

[0053] For example, the through-hole structure 11 can be provided on the support plate 13. The through-hole structure 11 can penetrate the support plate 13, and the thickness of the support plate 13 in the vertical direction (z direction) is greater than or equal to the axial dimension of the mounting hole 202. This ensures that the rubber joint 201 can completely pass through the through-hole structure 11 after being pushed out of the mounting hole 202. This avoids the rubber joint 201 from getting stuck in the through-hole structure 11 or interfering with the support plate 13 due to insufficient thickness of the support plate 13. This allows the rubber joint 201 to be smoothly discharged from the support base 1, improving the smoothness of the unloading operation.

[0054] Of course, the position and size of the through hole structure 11 can be adjusted according to actual needs, and this application embodiment does not further limit this.

[0055] In this embodiment, see continue to refer to Figure 1 and Figure 5 As shown, the unloading component 2 can be separately installed from the support base 1. The unloading component 2 may include a driving part 21, a positioning part 22, and a pushing part 23 arranged sequentially along the axial direction. The separate installation of the unloading component 2 from the support base 1 reduces the difficulty of transporting the disassembly device 100, facilitates adaptation to different disassembly operation requirements, and also facilitates the replacement of damaged parts, thus improving work efficiency. The driving part 21 can be used to receive external driving force.

[0056] In this embodiment, the external driving force can come from an external driving component 400 that can provide vertical (z-direction) driving force. The external driving component 400 can be a hydraulic driving component, an electric driving component, a manual driving force, etc. This embodiment does not impose further restrictions on the selection of the external driving component.

[0057] In some embodiments, see Figure 5 As shown, the drive unit 21 can be fixedly connected to the push unit 23. For example, the drive unit 21 can be welded to the push unit 23 or integrally formed, which can enhance the structural strength of the push-off part.

[0058] Of course, in some other embodiments, see Figure 5As shown, the drive unit 21 can also be detachably connected to the push unit 23. For example, a threaded connection, snap-fit ​​connection, or hinge connection can be used. When disassembly is required, the separate drive unit 21 and push unit 23 can be transported to the work area, and the drive unit 21 and push unit 23 can be detachably connected. After the disassembly is completed, the drive unit 21 and push unit 23 can be separated and removed from the work area. This facilitates component transportation and subsequent replacement of damaged components, reducing the cost of replacing damaged components.

[0059] In the embodiments of this application, combined with Figure 1 and Figure 5 As shown, the outer contour of the pushing part 23 can match the shape of the mounting hole 202. For example, when the mounting hole 202 is a circular hole, the outer contour of the pushing part 23 can be correspondingly set to a circle, so that the pushing part 23 can form a uniform fitting gap with the mounting hole 202 when passing through the mounting hole 202. In this way, the pushing part 23 can maintain a good coaxial state with the rubber joint 201 during the process of pushing the rubber joint 201, so that the driving force can be applied to the outer periphery of the rubber joint 201 more evenly, which is conducive to the smooth withdrawal of the rubber joint 201 from the mounting hole 202 and reduces the possibility of jamming or damage to the inner wall of the mounting hole 202 due to uneven local force.

[0060] In addition, in some embodiments, the outer contour dimension of the pushing part 23 may be smaller than the size of the mounting hole 202, so that the pushing part 23 can maintain a certain gap with the inner wall of the mounting hole 202 when it enters the mounting hole 202. This helps to reduce the possibility of collision or scratch between the pushing part 23 and the inner wall of the mounting hole 202, thereby reducing the risk of scratches or damage to the inner wall of the mounting hole 202.

[0061] It should be noted that the outer contour shape and size of the pushing part 23 can be determined according to actual needs, and no further limitation is made in this embodiment.

[0062] Continue to combine Figure 1 and Figure 5 As shown, the pushing part 23 may be provided with a cavity structure 231. The cavity structure 231 can be used to accommodate at least a part of the structure of the rubber joint 201. Under the action of external driving force, the pushing part 23 can pass through the mounting hole 202 and push the rubber joint 201, so that the rubber joint 201 is removed from the mounting hole 202.

[0063] In some embodiments, combined with Figure 1 and Figure 5As shown, the shape of the cavity structure 231 can match the end shape of the rubber joint 201 spindle, and the end of the cavity structure 231 away from the drive part 21 is an open structure. For example, when the end shape of the rubber joint 201 spindle is cylindrical, the cavity structure 231 can be a cylinder that matches the end of the cylindrical rubber joint 201 spindle. During the disassembly of the rubber joint 201, after the cavity structure 231 accommodates the end of the rubber joint 201 spindle, there can be a fitting gap between the inner wall of the cavity structure 231 and the end of the rubber joint 201 spindle. This facilitates the cavity structure 231 to accommodate or detach from the end of the rubber joint 201 spindle, and also avoids an offset greater than the fitting gap between the ejector 2 and the rubber joint 201, preventing the inner wall of the mounting hole 202 from being scratched due to contact between the pushing part 23 and the inner wall of the mounting hole 202.

[0064] It should be noted that the embodiments of this application do not impose further restrictions on the shape and size of the cavity structure 231, which can be selected according to the shape and size of the mandrel of the rubber joint 201.

[0065] Combination Figure 1 and Figure 5 As shown, the positioning part 22 can be provided on the outer peripheral wall of the pushing part 23 near the driving part 21. The positioning part 22 is used to abut against the end face of the motor rod 200 during the unloading process to limit the displacement of the unloading part 2 relative to the motor rod 200 in the vertical direction (z direction).

[0066] In some embodiments, combined with Figure 1 and Figure 5 As shown, the positioning part 22 can be a rod-shaped structure, such as cylindrical or rectangular, in order to reduce the weight of the positioning part 22.

[0067] Of course, in some other embodiments, the positioning part 22 can also be a fan-shaped structure. For example, the positioning part 22 can be fan-shaped, triangular, etc., thereby increasing the area between the positioning part 22 and the upper end surface of the motor rod 200, increasing the force-bearing surface, and reducing the possibility of scratches or deformation on the upper end surface of the motor rod 200. This application does not impose further limitations on the choice of the shape of the positioning part 22.

[0068] In some embodiments, combined with Figure 1 and 5 As shown, the positioning part 22 is a rod-shaped structure. One end of the rod-shaped structure is located outside the ejector 2, and the other end extends radially along the ejector 2 to the outer contour of the pushing part 23. The radially extended dimension of the rod-shaped structure is greater than half the inner diameter of the mounting hole 202 of the motor rod 200, so that the lower surface of the rod-shaped structure can abut against the upper end face of the motor rod 200 during the ejection process, thereby limiting the displacement of the ejector 2 relative to the motor rod 200 in the vertical direction.

[0069] For example, the rod-shaped structure can be cylindrical or rectangular, etc. This reduces the shape requirements of the material used in its fabrication, simplifying the fabrication process of the positioning part 22. The shape of the rod-shaped structure can be selected according to actual conditions, and this embodiment does not impose further limitations.

[0070] It should be noted that "the radial extension dimension of the rod-like structure is greater than half the inner diameter of the mounting hole 202 of the motor rod 200" means that when the unloading part 2 is placed on the mounting hole 202 of the motor rod 200, a part of it is located outside the mounting hole 202. This allows the rod-like structure to engage with the outside of the mounting hole 202 of the motor rod 200, preventing the unloading part 2 from falling off.

[0071] In some possible embodiments, see Figure 5 As shown, there are multiple positioning parts 22. These positioning parts 22 can be evenly distributed along the circumference of the unloading part 2, which ensures that each positioning part 22 is subjected to uniform force and reduces wear on the positioning parts 22.

[0072] In some possible embodiments, see Figure 5 As shown, the positioning part 22 can be fixedly connected to the pushing part 23, for example, by welding or integral molding, which can enhance the structural strength of the positioning part 22 and can be used without additional installation, thus improving work efficiency.

[0073] Of course, in some other embodiments, see Figure 5 As shown, the positioning part 22 can also be detachably connected to the pushing part 23, for example, by threaded connection, snap-fit, etc.

[0074] For example, when using a threaded connection, the pushing part 23 has a number of threaded holes matching the number of positioning parts 22. The positioning part 22 has an external thread that mates with the threaded hole and a locking nut that is movably connected to the positioning part 22. The locking nut can be threadedly engaged with the positioning part 22. During disassembly, the threaded end of the positioning part 22 is screwed into the threaded hole on the pushing part 23. After the positioning part 22 is screwed in to a suitable length as needed, the locking nut is tightened so that it abuts against the outer wall of the pushing part 23 to prevent the positioning part 22 from loosening or shifting under vibration conditions.

[0075] In some embodiments, there may be two locking nuts, which are tightened against each other. In this way, under vibration conditions, a large frictional force can be generated between the two locking nuts, making it difficult for them to rotate relative to each other, thereby effectively restricting the positioning part 22 from moving away from the pushing part 23.

[0076] It should be noted that the connection method between the positioning part 22 and the pushing part 23 can be selected according to specific needs, and the embodiments of this application do not impose further restrictions.

[0077] In some embodiments, see Figure 5 As shown, the material of the positioning part 22 can be a metal material, such as stainless steel.

[0078] Of course, in other embodiments, the material of the positioning part 22 may also be a non-metallic material, such as wood, to reduce the weight of the positioning part 22 and increase the comfort of holding the positioning part 22.

[0079] The motor rod 200 is placed and supported by the support base 1, so that the mounting hole 202 of the motor rod 200 is arranged vertically to maintain the stable posture of the motor rod 200. At the same time, a disassembly part 2 is provided, which includes a positioning part 22 and a pushing part 23 and is separately matched with the support base 1. During the disassembly process, the positioning part 22 abuts against the end face of the motor rod 200, which can limit the displacement of the disassembly part 2 relative to the motor rod 200 in the vertical direction (z direction). The outer contour of the pushing part 23 matches the shape of the mounting hole 202 and has a cavity structure 231 that can accommodate part of the structure of the rubber joint 201, so that the external driving force is transmitted to the rubber joint 201 more evenly, thereby reducing the jamming phenomenon of the rubber joint 201 and reducing the risk of damage to the inner wall of the mounting hole 202.

[0080] In some embodiments, combined with Figure 1 and Figure 5 As shown, the outer diameter of the pushing part 23 is smaller than the inner diameter of the mounting hole 202 of the motor rod 200, which makes it easier for the pushing part 23 to pass through the mounting hole 202 and push the rubber joint 201 out of the mounting hole 202.

[0081] In some embodiments, see Figure 5 As shown, the outer diameter of the driving part 21 is smaller than the outer diameter of the pushing part 23, and a transition part 24 is formed between the driving part 21 and the pushing part 23. The outer diameter of the transition part 24 gradually increases from the end near the driving part 21 to the end near the pushing part 23.

[0082] In some embodiments, the positioning part 22 may be disposed on the outer peripheral wall of the transition part 24.

[0083] For example, the transition portion 24 can be a conical structure, with the larger end of the conical structure located near the pushing portion 23.

[0084] Of course, in other embodiments, the transition portion 24 may also be a structure of other shapes, such as a cylinder, wherein the outer diameter of the cylinder may be smaller than that of the pushing portion 23 and larger than that of the driving portion 21.

[0085] This application does not further limit the specific shape of the transition section 24. In this way, the operational requirements are met while reducing the volume of the drive section 21 and the transition section 24, thereby reducing weight.

[0086] In some embodiments, combined with Figure 2 and Figure 5 As shown, the axial distance between the surface of the positioning part 22 facing the pushing part 23 and the end face of the pushing part 23 away from the driving part 21 is greater than or equal to the axial installation depth of the rubber joint 201 in the mounting hole 202.

[0087] In other words, when the pushing part 23 pushes the rubber joint 201, it needs to enter the mounting hole 202 a certain distance. This distance is greater than or equal to the axial installation depth of the rubber joint 201 in the mounting hole 202. During this distance, the positioning part 22 does not restrict the movement of the unloading part 2, so as to completely push the rubber joint 201 out of the mounting hole 202.

[0088] In some embodiments, see Figure 5 As shown, the unloading part 2 may be provided with a perforated structure 25. The perforated structure 25 penetrates the unloading part 2 radially. The perforated structure 25 can be used to allow an auxiliary positioning rod to be inserted to rotate and adjust the position of the unloading part 2.

[0089] In some embodiments, see Figure 5 As shown, multiple perforated structures 25 can be provided to meet different needs, and this application embodiment does not impose any limitations.

[0090] In some embodiments, see Figure 5 As shown, there are two perforated structures 25, which are arranged at intervals along the circumference of the unloading member 2.
