Description

Technical Field

[0001] This utility model relates to a power line erection device, belonging to the field of power line construction technology. Background Technology

[0002] In power line erection equipment, pulley assemblies play a crucial role in guiding, reducing friction, and protecting the cable during the cable pulling process. Their significance is reflected in the following aspects: Pulleys replace the sliding friction between the cable and the ground with rolling friction, significantly reducing traction force consumption and improving construction efficiency. As a crucial support point for power line erection in the air, pulley assemblies play a vital role in supporting and guiding the power line. However, current technology is not comprehensive and has the following drawbacks: During cable pulling operations, if the cable accidentally slips out of the pulley assembly, it will cause two problems: First, the pulley assembly cannot effectively assist in pulling the line, resulting in a significant reduction in cable pulling efficiency; second, the detached cable will get stuck in the pulley frame, creating frictional resistance that further hinders the cable pulling process and may even damage the cable or the pulley assembly.

[0003] To solve one of the above problems, there is an urgent need for a power line erection device. Utility Model Content

[0004] Based on the shortcomings of the existing technology, the technical problem to be solved by this utility model is: how to achieve smooth cable traction and reliable temporary fixation through the synergistic effect of adjustable pulley assembly, limit wheel assembly and cable fixing parts, while also having anti-detachment and anti-drag functions, and thus provide a power line erection device.

[0005] The power line erection device of this utility model includes a supporting crossbeam, characterized in that: a rod base is fixed in the middle of the supporting crossbeam, a main rod is installed on the upper surface of the rod base, a pipe clamp is provided at the upper end of the main rod, a first rod and a second rod are detachably installed at both ends of the supporting crossbeam, a pulley assembly is installed at the bottom end of the first rod and the second rod, a limiting wheel assembly that cooperates with the pulley assembly is installed in the middle of the supporting crossbeam, a cable fixing component A is installed on the first rod, and a cable fixing component B that cooperates with the cable fixing component A is installed on the second rod.

[0006] This application utilizes pipe clamps to fix the cable to existing pipes, serving as an important support point when the cable is erected in the air. The pulley assembly can support and guide the cable. This application has two states. In state one, the cable is located between the limiting wheel assembly and the pulley assembly. Both the limiting wheel assembly and the pulley assembly are in contact with the surface of the cable. During the cable pulling process, both the limiting wheel assembly and the pulley assembly can rotate. Neither of them will cause resistance to the cable pulling. Through this cooperation, it can prevent the cable from jumping out of the pulley assembly due to tension issues when moving inside the pulley assembly.

[0007] When the cable is pulled and temporary fixation is required, simply change the height of the pulley assembly relative to the supporting beam. Cable fixing parts A and B can be used to clamp the cable, completing the temporary fixation and preventing it from slipping off the pulley assembly. This provides good anti-drag functionality.

[0008] In any of the above embodiments, preferably, the limiting wheel assembly includes an upper wheel axle, on which a limiting wheel is rotatably mounted. The two ends of the limiting wheel are respectively vertically connected to axle rod A and axle rod B. Axle rod A passes through a supporting beam and a rod base, and nuts A and B are threadedly connected to the threaded section of axle rod A. The rod base and supporting beam are clamped between nuts A and B. Axle rod B passes through a supporting beam and a rod base, and nuts C and D are threadedly connected to the threaded section of axle rod B. The rod base and supporting beam are clamped between nuts C and D.

[0009] The modular design utilizes the fit between wheel axle hanger A and nuts A and B, as well as the fit between wheel axle hanger B and nuts C and D, to allow the limit wheel assembly, support beam, and hanger base to be detachably installed together, enabling rapid assembly of the hanger base, support beam, and limit wheel assembly.

[0010] In any of the above solutions, it is preferred that the limiting wheel be made of resin. Compared to metal, this provides protection for the cable.

[0011] In any of the above embodiments, preferably, a hanger clamp A is provided at the left end of the supporting beam, and the hanger clamp A is detachably installed at the upper end of the first hanger. A hanger clamp B is provided at the right end of the supporting beam, and the hanger clamp B is detachably installed at the upper end of the second hanger. The hanger clamp A can be easily connected to the first hanger, and the hanger clamp B can be easily connected to the second hanger, facilitating the assembly and disassembly of the first and second hangers. Furthermore, the hanger clamps A and B can be fixed at different positions on the first and second hangers to adjust the height of the pulley assembly relative to the supporting beam.

[0012] In any of the above embodiments, it is preferred that the boom clamp A includes clamp unit A and clamp unit B that cooperate with each other, clamp unit A and clamp unit B are detachably connected by connecting bolt B, and clamp unit B is welded to one end of the support beam.

[0013] In any of the above embodiments, it is preferred that the boom clamp B and the boom clamp A are symmetrically arranged and have the same structure.

[0014] In any of the above embodiments, the preferred embodiment is that the cable fixing component A includes a sliding sleeve A installed on the first hanger rod, the horizontal height of the sliding sleeve A being higher than that of the pulley assembly, and also includes a plug rod A that slides with the sliding sleeve A. The inner and outer ends of the plug rod A are respectively provided with a pipe clamp unit A and an end plate A. A compression spring A is sleeved on the plug rod A, and the two ends of the compression spring A are respectively supported on the first hanger rod and the end plate A.

[0015] In any of the above embodiments, preferably, the cable fixing component B includes a sliding sleeve B installed on the second hanger, the horizontal height of the sliding sleeve B being higher than that of the pulley assembly, and also includes an insert rod B that slides with the sliding sleeve B. The inner and outer ends of the insert rod B are respectively provided with a clamp unit B and an end plate B. A compression spring B is sleeved on the insert rod B, and the two ends of the compression spring B are respectively supported on the second hanger and the end plate B. The clamp unit A and the clamp unit B are connected by a clamp connecting bolt assembly to fix the cable in the fixing hole formed by the clamp unit A and the clamp unit B.

[0016] If the clamp unit A and clamp unit B are not connected, the compression spring A pushes the end plate A, causing clamp unit A to approach the first hanger, thus avoiding interference with the movement of the pulley assembly and the limit wheel assembly. The cable fixing component A and cable fixing component B are in the same state. When it is necessary to fix the cable, clamp unit A and clamp unit B need to be manually pulled closer, and then the clamp connecting bolt assembly is used to fix clamp unit A and clamp unit B, fixing the cable in the fixing hole formed by clamp unit A and clamp unit B.

[0017] In any of the above embodiments, it is preferred that the main lifting rod is a straight rod or an L-shaped rod.

[0018] Compared with the prior art, the present invention has the following beneficial effects: The power line erection device described in this utility model can be fixed to existing pipes using pipe clamps, serving as an important support point when the power line is erected in the air. The pulley assembly can support and guide the power line. This application has two states. In state one, the cable is located between the limiting wheel assembly and the pulley assembly. Both the limiting wheel assembly and the pulley assembly are in contact with the surface of the cable. During the cable pulling process, both the limiting wheel assembly and the pulley assembly can rotate. Neither of them will cause resistance to the cable pulling. Through this cooperation, it can prevent the cable from jumping out of the pulley assembly due to tension issues when moving inside the pulley assembly.

[0019] The power line erection device of this utility model, when the cable is pulled and needs to be temporarily fixed, only needs to change the height of the pulley assembly relative to the supporting beam. The cable can be clamped by cable fixing parts A and B to complete the temporary fixation and prevent it from slipping relative to the pulley assembly, thus having a good anti-drag function.

[0020] The power line erection device described in this utility model adopts a modular design. By utilizing the cooperation between wheel axle rod A and nuts A and B, and by utilizing the cooperation between wheel axle rod B and nuts C and D, the limit wheel assembly, support beam, and rod base can be detachably installed together, thereby completing the rapid assembly of the rod base, support beam, and limit wheel assembly.
