Description

Technical Field

[0001] The invention relates to a disassembly device, in particular to a disassembly device for a cone sleeve and a wedge of a high-speed railway terminal anchoring wire clamp. Background Art

[0002] The high-speed railway contact network line undertakes the important function of providing dynamic continuous and reliable electric energy to high-speed EMUs and ensuring the safe, reliable and punctual operation of trains all day long. The terminal anchor wire clamp is the most used and most important main load-bearing component of the high-speed railway contact network line. It is used to connect the contact wire and the load-bearing cable with the compensation device in series, and transfer the weight of the compensation device's weight to the contact wire and the load-bearing cable, so that the contact wire and the load-bearing cable are tightened, straightened and obtain the specified tension, providing a channel for the electric locomotive or EMU to smoothly take the current. The horizontal tension of the high-speed contact line is generally 25-40kN, and the load-bearing cable tension is 15-27kN. It belongs to a high-tension power supply line. The terminal anchor wire clamp is also subject to the above tension because it is connected in series in the loop. This is the static force of the terminal anchor wire clamp. When the locomotive passes, the contact network vibrates violently. In addition, additional forces such as swinging caused by wind in nature also act on the terminal anchor wire clamp, so the terminal anchor wire clamp is subjected to dynamic forces of high tension for a long time. As time goes by, the maintenance of contact network lines and the replacement of various components after their service life expires are necessary measures to ensure railway safety. Among them, the removal of the cone sleeve and wedge inside the terminal anchor clamp has become an indispensable link.

[0003] Affected by the high tension of the contact network line, the removal of the terminal anchor clamp cone sleeve and wedge also requires a large force. However, the current disassembly at the construction site is still done manually, which is time-consuming, labor-intensive and inefficient. Summary of the invention

[0004] The purpose of the present invention is to provide a disassembly device for a cone sleeve and a wedge of a high-speed railway terminal anchoring wire clamp, which can easily and quickly combine and disassemble the cone sleeve and the wedge of the terminal anchoring wire clamp to improve the working efficiency.

[0005] In order to solve the above technical problems, the present invention discloses a disassembly device for a cone sleeve and a wedge of a high-speed railway terminal anchoring wire clamp, comprising a connecting sleeve, a stopper connected to the upper end of the connecting sleeve, and a manual hydraulic pliers connected to the lower end of the connecting sleeve.

[0006] Furthermore, the connecting sleeve and the stopper are connected via a pin.

[0007] Furthermore, the connecting sleeve is connected to the manual hydraulic pliers through threads.

[0008] Furthermore, the connecting sleeve is a sleeve with openings at both ends and a hollow structure in the middle. Two opposite holes are provided at the upper part of the sleeve near the ends, and threads are provided on the lower inner wall of the sleeve.

[0009] Furthermore, the stopper includes an end cover and a connecting rod connected to the end cover, the connecting rod is inserted into the connecting sleeve, and the end cover fits with the top end of the connecting sleeve.

[0010] Furthermore, the connecting rod is provided with a through hole corresponding to the hole.
