Abstract

The invention provides a rail collection guidance and rail pushing trolley and a long steel rail transport train set. The rail collection guidance and rail pushing trolley comprises a trolley body and telescopic arm assemblies; each telescopic arm assembly comprises a telescopic arm body, a sliding arm which is arranged outside the telescopic arm body in a sleeving mode and a first hydraulic cylinder used for driving the telescopic arm body to move in the axial direction of the sliding arm; the two sides of each sliding arm are supported by the trolley body through a first strutting piece and a second strutting piece; a clamp used for clamping steel rails is fixedly connected with the bottom end of each telescopic arm body. According to the rail collection guidance and rail pushing trolley and the long steel rail transport train set, each clamp can be driven to move up and down through the stretching and shortening of a piston rod of the corresponding first hydraulic cylinder; due to the fact that the volume of the hydraulic cylinders is smaller, the carrying capacity is stronger, the reliability is stronger, large-stroke lifting and dropping can be completed within a vehicle limit range, the safety and the efficiency are improved, and the working environment is improved.

Description

technical field [0001] The invention relates to mechanical technology, in particular to a rail receiving guide, a rail shifting trolley and a long rail transport car set. Background technique [0002] Steel rails are the main components of railway tracks. High-quality steel rails can ensure the smooth and safe operation of trains. However, if the rails are worn or worn out, it will affect the safety of the train and should be recycled in time. [0003] In the prior art, when reclaiming the old rails replaced on the railway line, the old rails are first clamped with special clamps, and then the on-site operators lift the clamps and drag the rails to the corresponding transport vehicles , to realize the recovery of rails. [0004] The disadvantage of the prior art is that the movement of the jig is completely dependent on the manual operation of the operator, the operation process is time-consuming, labor-intensive, low-efficiency, and there are certain safety hazards. Con...
