Carriage used for repairing power transmission line

Abstract

The invention provides a carriage used for repairing a power transmission line. The power transmission line comprises power transmission towers and power transmission wires between adjacent power transmission towers, the carriage is connected with a carrying rope and a traction rope, other ends of the carrying rope and the traction rope are connected with a terminal mounting bracket, the carriage comprises a traction device and a crawler arranged on the lower end of the traction device, and a walking vehicle is arranged on the carrying rope and the traction rope. By employing the carriage, repairing and mounting demands of the power transmission line in different environments can be satisfied, the transportation convenience is improved, the equipment manufacture and maintenance cost is reduced, and the trafficability and safety of the walking vehicle are improved.

Description

technical field [0001] The invention relates to a support vehicle, in particular to a support vehicle used for emergency repair of power transmission lines. Background technique [0002] During the construction of power transmission and transformation projects, various engineering materials and construction equipment need to be transported. Since the areas where the project passes are mostly mountainous areas with sparsely populated areas and poor traffic conditions; in addition, the iron towers are gradually increasing, and the transportation volume of tower building materials is increasing. The traditional transportation methods in the past cannot meet the transportation of a large number of heavy materials with complex terrain conditions. Therefore, it is necessary to provide a support vehicle for emergency repair of transmission lines to meet the requirements of delivering construction materials and construction equipment to designated locations, improve transportation e...

AI Technical Summary

Problems solved by technology

[0003] The inventor finds that there are following deficiencies in transportation equipment through long-term observation and research: 1. does not possess walking device, and cannot overcome the harsh geographical environment in mountainous areas

② It is impossible to install a suitable type of winch and a suitable truss mechanism according to the actual work needs, and the adaptability is poor

③The height of the truss cannot be adjusted according to the needs, and the erection and emergency repair of overhead transmission lines cannot be completed in special environments

④Due to the complex terrain of the cableway erection and the undulating heights, the trolley cannot rotate with the change of the angle of the traction cable along the direction of the cableway. As a result, when the traction load is large, it is difficult for the trolley to pass through the support, and the traction cable is easy to wear and even cannot pass through the support.
