An operating vehicle for overhauling large-span transmission lines

Abstract

The invention discloses a working vehicle for overhauling large span transmission lines, and the vehicle comprises a working cage, a main wheel frame horizontally mounted on the top of the working cage, and main pulleys movably mounted on the main wheel frame. The length of the main wheel frame is greater than that of the working cage. The main pulleys are mounted at two ends of the main wheel frame respectively. The working cage is also articulated with an auxiliary wheel frame. The two ends of the auxiliary wheel frame top are respectively provided with auxiliary pulleys, and the bottom is equipped with a handle. The handle can rotate the auxiliary wheel frame around the hinge shaft to change the cooperation between the main pulleys and the cable. The invention has the beneficial effects that the working cage is directly connected fixedly with the main wheel frame so as to reduce the shaking problem existing in the working process. And the main wheel frame has a longer size, which further enhances the stability in the direction of travel to avoid overturning. With the manually rotating auxiliary wheel frame, the contact between the main pulleys and the cable can be changed for barrier-free pass.

Description

technical field [0001] The invention belongs to the technical field of transmission line maintenance, and in particular relates to an operation vehicle for maintenance of large-span transmission lines. Background technique [0002] Large spans with a height of more than 100 meters are high-rise structures. Large spans in power transmission lines are mainly subjected to wind loads, earthquake loads and installation loads, among which wind loads are the most dominant. Large spans are generally located on the coasts of rivers, lakes, rivers and seas, and the wind environment is harsh, so the dynamic response under the action of wind load is particularly strong. Therefore, large spans often adopt a combination of damping wire clamps and shockproof hammers. Due to the importance and particularity of large spans, eliminating the defects of large spans often requires high standards and high efficiency. However, due to the large span and towering heights, high-altitude operations, ...

Therefore, in the traditional way of eliminating gaps, operators not only have to overcome the difficulties of hanging their bodies in the air and making it difficult to exert force when moving along the line, but also travel slowly, take a long time to go out of the line, consume a lot of physical strength, and work efficiency is low, and the psychological pressure of the personnel is huge.
