Description

Technical Field

[0001] This utility model relates to the field of high-voltage power cable technology, and in particular to a high-speed train locomotive terminal installation tool. Background Technology

[0002] Currently, the terminals used for electrical connections in high-speed train locomotives are mainly divided into two types: heat-shrink terminals and prefabricated rubber terminals. Prefabricated rubber terminals have advantages such as stable electrical performance, minimal impact from installation personnel, and good waterproof sealing performance, and are widely used in various power transmission applications. Prefabricated rubber terminals are generally equipped with soft copper wire conductors and EPDM rubber insulated cables. The conventional assembly method involves tying a rope to the cable, with the other end of the rope connected to a lever hoist to pull the terminal for assembly. Because the cable is relatively soft and cannot withstand force, and the cable and terminal have an interference fit, a large amount of power is required, making it very difficult to assemble the terminal onto the cable. Assembly requires the use of a large hydraulic device to complete the installation, making the equipment bulky and difficult to carry and transport. Furthermore, the installation environment for locomotive terminals is the confined space on the roof or under the locomotive, making it impossible to use larger equipment. Utility Model Content

[0036] Please see Figure 1 and Figure 2 This utility model discloses a high-speed train locomotive terminal installation tool, comprising a support frame 100, a clamp assembly 200, a lever hoist 300, and a traction assembly 400. The clamp assembly 200 is installed at one end of the support frame 100 along its length and is used to clamp the terminal body 500. The lever hoist 300 is installed at the other end of the support frame 100 along its length and has a chain hook 310. The middle portion of the traction assembly 400 is used to thread the terminal body 500 through it. One end of the traction assembly 400 is detachably connected to the chain hook 310 of the lever hoist 300, and the other end is detachably connected to a cable 600. The lever hoist 300 is used to pull the support frame 100 and the terminal body 500 along the length of the support frame 100, assembling the terminal body 500 onto the cable 600.

[0037] The terminal body 500 can be clamped to one end of the support frame 100 by the clamp assembly 200. One end of the traction assembly 400 is connected to the cable 600, which passes through the terminal body 500 and connects to the chain hook 310 of the lever hoist 300. The operator controls the extension and retraction of the lifting chain of the lever hoist 300 by moving the handle of the lever hoist 300 up and down, pulling the support frame 100 and the terminal body 500 to assemble the terminal body 500 onto the cable 600. The overall structure is simple and lightweight, with the installation tools weighing approximately 10kg (support frame 100 approximately 3kg; lever hoist 300 approximately 3kg; other factors approximately 4kg). By pulling the lever hoist 300 to move the terminal body 500 and the support frame 100 together and assemble them onto the cable 600, there is no need to move the cable 600, making it suitable for on-site installation environments in confined spaces such as the roof or underside of high-speed trains.

[0038] In some embodiments, see Figure 1 and Figure 2 The clamping assembly 200 includes a clamping plate 210, which is detachably connected to the support frame 100. The clamping plate 210 has a slot 211 into which the terminal body 500 can extend. When the clamping assembly 200 clamps the terminal body 500, the clamping plate 210 abuts against a protrusion on the terminal body 500. The operator controls the extension and retraction of the lifting chain of the lever hoist 300 by moving the handle up and down, pulling the support frame 100 to move. The clamping plate 210 on the support frame 100 pushes the terminal body 500 to move, assembling the terminal body 500 onto the cable 600.

[0039] In some embodiments, see Figure 1 and Figure 2 Multiple clamping plates 210 are provided, and the multiple clamping plates 210 are spaced apart along the length of the support frame 100. With multiple clamping plates 210, when the operator turns the handle of the lever hoist 300, the multiple clamping plates 210 simultaneously push the terminal body 500, so that the contact points between the terminal body 500 and the multiple clamping plates 210 are evenly stressed, ensuring that the terminal body 500 can be smoothly assembled onto the cable 600.

[0040] In some embodiments, see Figure 1 and Figure 2 The clamping plate 210 is made of nylon. The nylon clamping plate 210 is easy to process, has good strength, and will not scratch the terminal body 500.

[0041] In some embodiments, see Figure 1 , Figure 3 and Figure 4The traction assembly 400 includes a buckle 410, a connecting rod 420, and a connecting sleeve 430. The connecting rod 420 is used to pass through the terminal body 500. One end of the connecting rod 420 is detachably connected to the buckle 410, and the other end is detachably connected to the connecting sleeve 430. The buckle 410 is detachably connected to the chain hook 310 of the lever hoist 300, and the connecting sleeve 430 is used for detachable connection to the cable 600. The various parts of the traction assembly 400 can also be disassembled and assembled at any time for easy carrying and transportation.

[0042] In some embodiments, see Figure 1 , Figure 3 and Figure 4 One end of the connecting rod 420 is provided with a T-shaped protrusion 421, and the fastener 410 is provided with a T-shaped groove 411. The T-shaped protrusion 421 extends into the T-shaped groove 411, and the fastener 410 is provided with a connecting hole through which the chain hook 310 of the lever hoist 300 passes. By setting the T-shaped protrusion 421 and the T-shaped groove 411 to cooperate and connect, the connecting rod 420 and the fastener 410 are tightly connected, ensuring the tensile strength of the connecting rod 420 and the fastener 410 along the length of the support frame 100 is stable. The T-shaped groove 411 with a larger cross-sectional area is provided on the fastener 410, and the T-shaped protrusion 421 with a smaller cross-sectional area is provided on the connecting rod 420, which facilitates the connection rod 420 to pass through the terminal protrusion.

[0043] In some embodiments, see Figure 1 , Figure 4 and Figure 5 The connecting sleeve 430 includes a first connecting portion 431, a transition portion 432, and a second connecting portion 433 connected in sequence. The first connecting portion 431 is detachably connected to the connecting rod 420, and the second connecting portion 433 is detachably connected to the cable 600. The outer diameter of the first connecting portion 431 is smaller than the outer diameter of the second connecting portion 433. The transition portion 432 is tapered, and its outer diameter gradually increases in the direction away from the first connecting portion 431. The tapered transition portion 432 allows it to pass smoothly through the terminal body 500 when it is assembled onto the cable 600, and it also guides the third connecting portion through the terminal body 500.

[0044] In some embodiments, see Figure 1 , Figure 4 and Figure 5 One end of the connecting rod 420 is provided with a first threaded hole 422, and the first connecting part 431 is provided with an external thread, and the first connecting part 431 is threadedly connected to the first threaded hole 422. The connecting rod 420 is threadedly connected to the connecting sleeve 430, which is convenient for disassembly and assembly and easy to carry and transport.

[0045] In some embodiments, see Figure 1 , Figure 2 and Figure 5 The second connecting part 433 is provided with a second threaded hole 4331. One end of the cable 600 is provided with an external thread. The cable 600 is screwed into the second threaded hole 4331 and connected to the connecting sleeve 430. The cable 600 and the connecting sleeve 430 are threadedly connected, which makes disassembly and assembly convenient.

[0046] In some embodiments, see Figure 1 and Figure 2 The support frame 100 includes a first bracket 110 and a second bracket 120, which are arranged sequentially along the length of the support frame 100. The first bracket 110 and the second bracket 120 are detachably connected by bolts. A clamp assembly 200 is connected to the first bracket 110, and a lever hoist 300 is connected to the second bracket 120. The support frame 100 is composed of two parts connected together by a bolt assembly, allowing for easy disassembly and assembly. The remaining parts of the installation tools can also be disassembled and assembled at any time, facilitating transport and carrying.
