Description

A high-speed railway catenary maintenance device

technical field

The invention relates to the technical field of railway catenary maintenance equipment, in particular to a high-speed railway catenary maintenance device.

Background technique

In recent years, my country's high-speed railway has developed rapidly. Whether the high-speed railway catenary is in good working condition is a necessary factor to ensure the normal operation of the high-speed railway. As the catenary is used for a long time, various components of the catenary, such as: insulation devices, wires, and various supporting devices, will be worn to varying degrees. Therefore, railway operators need to carry out maintenance operations on the high-speed railway catenary on a regular basis. During the overhaul operation of the high-speed railway catenary, the track-type car ladder that can move along the track is usually used to overhaul the relevant components of the high-speed railway catenary, but the existing high-speed railway catenary maintenance device still exists in the actual use process. Some deficiencies, it still has the following disadvantages in actual use:

Most of the existing high-speed railway catenary maintenance devices are composed of rail wheels, car bodies, and ladders. However, the rail-type ladders are usually not equipped with anti-dumping components, and generally can only be used on relatively gentle tracks. When the car ladder moves to the curve of the railway and one side of the track is higher than the other side, there is a big safety hazard for railway workers to perform maintenance work on the maintenance platform at this time. It is also necessary to ensure that the force is even, otherwise, on the flat track, it will also roll over due to uneven force on the maintenance platform. Supports require other means of servicing them.

In conclusion, how to prevent the rail-type car ladder from rolling over due to various reasons and at the same time facilitate the maintenance of the supporting devices standing beside the rails is a technical problem that those skilled in the art need to think about.
