Ballast raking device and long steel rail vehicle set

Abstract

The invention provides a ballast raking device and a long steel rail vehicle set. The ballast raking device comprises a push rod assembly, a moving assembly, a linkage assembly, a rotating arm assembly and an execution assembly which are sequentially connected; the push rod assembly comprises a push rod base and a push rod hinged to the push rod base; the moving assembly comprises a supporting table and a sliding part, the sliding part is hinged to the push rod, and one end of the sliding part is movably connected to the supporting table; the linkage assembly comprises a connecting frame and an elastic part, the connecting frame is hinged to the other end of the sliding part, and one end of the elastic part is fixedly arranged on the connecting frame; the rotating arm assembly comprises a rotating arm support and a rotating arm hinged to the rotating arm support, the middle of the rotating arm is connected with the other end of the elastic part, and the end, away from the rotating arm support, of the rotating arm is connected with the execution assembly; and a check block is further fixedly arranged on the rotating arm support and used for limiting the rotating range of the rotating arm. According to the invention, the ballast can be continuously and automatically pushed open without stopping, meanwhile, the labor cost can be reduced, and the operation efficiency and safety are improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a ballast removal device and a long rail car set. Background technique [0002] The long rail car group is a special car group for transporting welded long rails, which is composed of a variety of special vehicles with different functions and structures. In the construction of seamless railway lines, the long rail car group is responsible for the long rail Tasks of loading, transporting, unloading and recycling old rails. For example, the long rail car unit has the function of unloading the transported rails to both sides of the line. In order to store the unloaded rails on both sides of the line smoothly and ensure that the rail surface of the unloaded rails is not higher than the rail surface of the line, it must Level the protruding ballast on both sides of the line. That is to say, in order to make the rails have a stable and safe storage space, it is necessary to dig out ...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned devices need to be installed and disassembled manually during the operation process, which takes a long time and the operation efficiency is low

Moreover, when there are heavy obstacles such as waste rails buried in the ballast, hidden obstacles cannot be identified in advance, and collisions will occur when encountering operations, which will damage the operating devices and even endanger driving safety.
