Mountain heavy-load monorail transport vehicle for overhead transmission line construction

Abstract

The invention discloses a mountain heavy-load monorail transport vehicle for overhead transmission line construction in the technical field of rail transport vehicles. The vehicle comprises a monorail transport rail laid on an overhead transmission line, and the monorail transport rail is provided with a trailer for bearing goods and a machine head for pulling the trailer to advance. A roller assembly is arranged at the bottom of the trailer for bearing goods, the roller assembly comprises a disc brake pad for active braking and hydraulic calipers, the machine head and the trailer are connected through a pressure relief type buffer device, and a pressure relief bypass of the pressure relief type buffer device is in control connection with the hydraulic calipers. According to the invention, the gasoline machine head can travel and transport on a monorail transport track laid on the overhead transmission line, so that the problems of high difficulty and low efficiency of overhead transmission line construction material transportation in the current power industry can be effectively solved; and the braking response enthusiasm of the transport vehicle can be improved, and the performance loss of a machine head braking system during braking of the heavy-load transport vehicle can be reduced.

Description

technical field [0001] The invention relates to the technical field of rail transport vehicles, in particular to a mountain heavy-duty monorail transport vehicle for overhead power transmission line construction. Background technique [0002] The construction of overhead transmission lines of various voltage levels is basically divided into four major sub-processes: foundation construction, erection tower construction, stretching and setting-out construction, and attachment installation. The foundation construction needs to enter the site sand and gravel, reinforced concrete, anchor bolts and other materials; the erection tower construction needs to enter the site tower materials, iron tower bolts, construction poles, motorized winches, steel wire ropes and other tools; Enter the pay-off block, lever block and other tools; the installation of accessories needs to enter various tools and electrical fittings. All kinds of materials need to rely on transportation to reach the ...

AI Technical Summary

Problems solved by technology

[0003] In order to avoid densely populated areas, overhead transmission line towers are mostly located in mountainous areas with sparse population and poor transportation conditions, and transmission line projects often encounter high mountains and hills, mountainous hills, vegetation is not allowed to be cut, narrow muddy roads or even no Complex and harsh comprehensive road conditions such as roads can pass, making transportation difficult

[0004] In addition, the existing rail transport vehicles are generally only equipped with a braking system at the nose end, and the trailer end used to load the cargo is generally passively braked. The weight of parts and other parts is relatively large. If the existing head braking method is used to consider the heavy-load inertia of the transport vehicle, it is necessary to intervene in the braking system in advance or extend the braking distance, and at the same time, the performance loss of the braking system may be greatly increased.
