Steel rail bending trolley for steel rail welding repair engineering

Abstract

The invention discloses a steel rail bending trolley for steel rail welding repair engineering. The steel rail bending trolley for the steel rail welding repair engineering comprises a frame, at leastfour telescopic supporting legs, a steel rail clamping mechanism, steel rail guiding mechanisms, a running mechanism and a power system. The telescopic supporting legs are arranged on the frame and correspondingly located on the outer sides of two steel rails which are arranged in parallel to drive the frame to move vertically in a reciprocating mode; the steel rail clamping mechanism is arrangedon the frame and used for vertically clamping the to-be-bent steel rail for lifting; the steel rail guiding mechanisms are arranged on the frame and used for limiting left-right movement of the to-be-bent steel rail in the operation process; the running mechanism is arranged on the lower part of the frame and used for driving the frame to move in the length direction of the steel rails; and the power system is used for providing power drive for the four telescopic supporting legs, the steel rail clamping mechanism and the running mechanism. According to the steel rail bending trolley for thesteel rail welding repair engineering, a mechanical and vertical steel rail lifting method is adopted, the steel rails do not interfere with rail spikes in the bending process, and steel rail bendingoperation which cannot be finished by an existing track jack is realized.

Description

technical field [0001] The invention relates to the technical field of rail welding restoration engineering, in particular to a rail bending trolley for rail welding restoration engineering. Background technique [0002] With the rapid development of my country's railways, the laying of seamless lines is becoming more and more extensive. According to the survey, there are about 10% of the welded joints in the seamless line with serious damage, which has become the weakest link of the railway line; in addition, the curved section is the most severely worn section of the rail, and the rail in this section needs to be replaced. The rail welding restoration project was produced under this background. [0003] The rail welding repair project is to cut off the damaged rail and connect the new rail in a "skylight", so that the seriously damaged joint of the rail and the rail at the worn curve section are replaced in sections. [0004] In order to realize line locking welding in t...

AI Technical Summary

Problems solved by technology

In this method, in order to clear the spikes during the bending process, sleepers must be placed at the bottom of the rail; and the method of bending the rails entirely by manpower using a crowbar is heavy and random, and it is easy to cause the amount of bending to be unable to be accurately controlled , The problem of excessive rail stress

If the road lifter is used to assist, there will be problems such as too small amount of road lifting and poor mechanical stability during operation.
