Description

Technical Field

[0001] This utility model belongs to the field of integral dropper installation technology, and in particular relates to an integral dropper installation positioning tool. Background Technology

[0002] In the overhead contact system of electrified railways, the contact wire is subjected to an upward tension through droppers to counteract the effect of gravity and keep the contact wire horizontal. However, in actual construction, the upper end of the dropper is first fixedly connected to the catenary, and then the lower end of the dropper is fixed to the contact wire. But when fixing the lower end of the dropper to the contact wire, one worker at height needs to lift the contact wire to a suitable height, and then another worker at height needs to fix it. This results in high labor intensity for workers at height and low work efficiency. Summary of the Invention

[0003] This utility model provides an integral dropper installation and positioning fixture to overcome the shortcomings of the prior art.

[0004] The technical solution adopted by this utility model is: an integral dropper installation and positioning fixture, including a rod-shaped body, the upper part of which is provided with a first hook groove and the lower part is provided with a plurality of second hook grooves, and the first hook groove and the second hook groove are located on the same side; the first hook groove is upper hook-shaped for hooking the load-bearing cable, and the second hook groove is lower hook-shaped for hooking the contact wire.

[0005] Both the first and second hook grooves are fitted with nylon sheaths.

[0006] Both the first and second hook grooves are C-shaped hook grooves.

[0007] The rod-shaped body is an aluminum alloy rectangular tube.

[0008] The first and second hook grooves are formed on the side wall of the aluminum alloy rectangular tube.

[0009] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model eliminates the need for additional personnel to lift the contact wire, allowing a single person to complete the dropper installation operation, thus simplifying the work process. By combining a first hook groove with several second hook grooves, it can quickly match installation scenarios with different structural heights of the catenary and contact wire. It eliminates the need for frequent tool changes, enabling the installation of droppers at different structural heights, thereby reducing the labor intensity of high-altitude workers and improving work efficiency.

[0010] 2. By embedding nylon sleeves in the first and second hook grooves, this utility model effectively prevents the rectangular tube body from scratching the contact line and the load-bearing cable, while also increasing the friction between the contact line, the load-bearing cable and the hook-shaped groove, thus reducing slippage during operation.

[0011] 3. The rod-shaped body of this utility model is made of high-strength aluminum alloy rectangular tube, which reduces the weight by 40%-50% compared with traditional steel rectangular tube, greatly reducing the burden of carrying and operating for high-altitude workers.

Detailed Implementation

[0013] The following is in conjunction with the appendix Figure 1-6 The present invention will be described in detail with reference to specific embodiments.

[0014] A single-piece dropper installation and positioning fixture includes a rod-shaped body 1. The upper part of the rod-shaped body 1 has a first hook groove 1-1, and the lower part has several second hook grooves 1-2, with the first hook groove 1-1 and the second hook grooves 1-2 located on the same side. The first hook groove 1-1 is upper-hook shaped for hooking the catenary cable 3, and the second hook grooves 1-2 are lower-hook shaped for hooking the contact wire 4. This fixture can quickly adapt to installation scenarios with different structural heights, eliminating the need for frequent tool changes and improving work efficiency.

[0015] Specifically, both the first hook groove 1-1 and the second hook groove 1-2 are fitted with nylon sheaths 2, which effectively prevent the rectangular tube body 1 from scratching the contact line 4 and the load-bearing cable 3, while also increasing the friction between the contact line 4, the load-bearing cable 3 and the hook-shaped groove, reducing slippage during operation.

[0016] Specifically, the rod-shaped body 1 is preferably a high-strength aluminum alloy rectangular tube, which reduces the weight by 40%-50% compared to traditional steel rectangular tubes, greatly reducing the carrying and operating burden for high-altitude workers.

[0017] Specifically, both the first hook groove 1-1 and the second hook groove 1-2 are C-shaped hook grooves.

[0018] Specifically, the first hook groove 1-1 and the second hook groove 1-2 are formed on the side wall of the aluminum alloy rectangular tube.

[0019] During the actual construction, the tooling is first suspended on the catenary cable 3 through the first hook groove 1-1 at its upper part. Then, the contact wire 4 is raised to a suitable height and inserted into the corresponding second hook groove 1-2. The tooling is now installed. At this time, the contact wire 4 has been raised to a suitable height with the help of the tooling, and the construction personnel can directly carry out the installation of the dropper. After the dropper is installed and inspected and qualified, the contact wire 4 is first removed from the second hook groove 1-2 in the horizontal direction, and then the tooling is removed from the catenary cable in the vertical direction, thus completing the construction.

[0020] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of implementation of the present utility model. Therefore, all equivalent variations made based on the content described in the claims of the present utility model should be included within the scope of the claims of the present utility model.
