[0028] Example 1

[0029] Track plate bodies 10 are typically provided with track plate axles 11 at both ends, and adjacent track plate axles 11 are connected by track end connectors 12, such as... Figures 1 to 3 As shown, a tool for removing track end connectors includes a top support section abutting against the end face of the end connector 12 and a force application section connected to the top support section on the side away from the end connector 12. In use, the top support section is inserted between the tracks and abuts against the end face of the end connector 12. The force application section is the force-bearing end, which is a striking end that withstands external force. By striking the force application section, the top support section pushes out the end connector 12 and removes it.

[0030] The force-applying section includes a cylindrical block 1, and the top support section includes a triangular prism rod 2 connected to the cylindrical block 1, such as... Figure 2As shown, the inner diameter d1 of the cylindrical block 1 is greater than the inner diameter d2 of the circumscribed circle S of the triangular prism rod 2, which makes the force receiving area of the cylindrical block 1 as the force receiving end relatively larger and more stable and reliable.

[0031] As shown in Figure 1 , Figure 3 , the triangular prism rod 2 includes a top end face 3 abutting against the end connector 12, a bottom end face 4 connected with the cylindrical block 1, and a side end face 5 connected between the top end face 3 and the bottom end face 4, and the triangular prism rod 2 further includes a side edge 8 connected between adjacent side end faces 5. The end of the triangular prism rod 2 near the bracing section is provided with a plug-in unit, which is used to meet the disassembly requirement when the track gap is small, that is, when the track gap is small, the disassembly tool can still be conveniently inserted between the tracks through the plug-in unit to brace and disassemble the end connector, which improves the inclusiveness of the operation space of the disassembly tool and also improves the disassembly efficiency and stability.

[0032] As shown in Figure 3 , the plug-in unit is provided on the top end face 3 and the side end face 5, and the plug-in unit includes plug-in grooves 6 symmetrically provided on the adjacent two side end faces 5, the plug-in grooves 6 extend to the top end face 3 and form plug-in ports 7 on the top end face 3, and the plug-in grooves 6 and the plug-in ports 7 are triangular in shape. The groove depth of the plug-in groove 6 and the opening size of the plug-in port 7 are set according to the gap between the tracks under specific working conditions, and the triangular plug-in groove 6 is matched with the shape of the triangular prism rod 2, which can reduce the manufacturing difficulty and improve the use stability.

[0033] In use, the triangular prism rod 2 is inserted between the tracks, and the plug-in unit can assist the insertion of the triangular prism rod 2 between the tracks, at this time the top end face 3 of the triangular prism rod 2 abuts against the end face of the end connector 12 and braces it, and the cylindrical block 1 is subjected to a knocking force, so that the end connector 12 is knocked out of the plate shaft 11, and the disassembly of the end connector 12 is realized.

[0034] Embodiment Two

[0035] As shown in Figure 4 , Figure 5 , the difference between this embodiment and embodiment one is that the length of the cylindrical block 1 is greater than the length of the end connector 12 in the axial direction of the triangular prism rod 2, that is, the cylindrical block 1 is thicker in the length direction, which can further improve the bearing capacity of the cylindrical block 1 as the force receiving end.

[0036] Meanwhile, an adjustment hole 9 is provided in the middle of the cylindrical block 1. The triangular prism rod 2 is connected to the cylindrical block 1 in the adjustment hole 9. An adjustment rod is provided on the bottom end face 4 of the triangular prism rod 2. The adjustment rod extends into the adjustment hole 9 and is connected to the cylindrical block 1. The adjustment rod can be fixedly connected to the cylindrical block 1 in the adjustment hole 9 or movably connected. When movably connected, the length of the triangular prism rod 2 can be adjusted according to the usage requirements. Those skilled in the art can make corresponding designs according to actual needs.

[0037] In this embodiment, the adjusting rod and the cylindrical block 1 are movably connected. Specifically, an internal thread is provided in the adjusting hole 9, and an external thread is provided on the adjusting rod to match the internal thread. The triangular prism rod 2 is threadedly connected to the cylindrical block 1 through the adjusting rod. When the triangular prism rod 2 is rotated, the adjusting rod rotates and extends within the adjusting hole 9, thereby adjusting the overall length of the triangular prism rod 2 and improving the versatility of the disassembly tooling.

[0038] The adjusting hole 9 has a through-slot structure, which facilitates tooling processing and can also increase the extension range of the adjusting rod. A power drive rod is connected to the end face of the cylindrical block 1 away from the end connector 12. That is, the striking force operation of the cylindrical block 1 can be replaced by manual striking through driving components such as hydraulic cylinders and motors, which can improve disassembly efficiency and work safety, and reduce the labor intensity of workers.

[0039] Example 3

[0040] like Figure 6 As shown, the difference between this embodiment and embodiment two is that the insertion groove 6 includes at least two sets of insertion grooves opened at different side edges 8. The groove depth of the insertion groove 6 in different insertion groove sets is different. Each insertion groove set is adapted to the track requirements under a certain working condition, so as to further improve the applicability and versatility of the disassembly tooling.

[0041] This embodiment includes three sets of insertion slots, specifically as follows: Figure 6 As shown in M1, M2, and M3, the insertion slots at M2 and M3 are not shown. Those skilled in the art can create them according to actual depth and width requirements. In this embodiment, the insertion slots 6 at M1, M2, and M3 have different depths, and the three insertion slot groups can be adapted to three types of track requirements.
