Abstract

The invention provides a rail pulling and aligning device, which comprises a transverse slippage mechanism fixed on a vehicle frame, vertical slippage mechanisms connected on two sides of the transverse slippage mechanism and longitudinal slippage mechanisms connected at the lower ends of the vertical slippage mechanisms. The rail pulling and aligning device is characterized in that rail clamping mechanisms are arranged in the middles of the longitudinal slippage mechanisms, and a front rail lifting mechanism and a rear rail lifting mechanism are correspondingly arranged on the front side and the rear side of each longitudinal slippage mechanism. An operator can operate the rail pulling and aligning device without matching of other operators so as to pull two steel rails to be welded to appropriate positions and align the two steel rails to the appropriate positions, thereby providing preparation for welding work of a welding machine, shortening welding operation preparing time and simultaneously decreasing the number of operating workers. The rail pulling and aligning device has the advantages of being high in work efficiency, flexible and convenient to operate, reliable in performance and the like, and the problems of the rail pulling and aligning in steel rail welding process can be solved.

Description

[0001] technical field [0002] The invention relates to a railway rail alignment device, which belongs to the technical field of railway machinery design and manufacture. Background technique [0003] In the welding construction of seamless railway rails, because the positions of the two rails to be welded cannot be placed exactly the same, and the current welding machine cannot directly clamp the two rails to be welded, it is necessary to use certain methods or equipment to The two steel rails to be welded are pulled to the appropriate position and aligned to ensure that the welding machine can correctly clamp and weld the steel rails. At present, there are mainly two ways to align the existing rails. One is to manually use a small rail pulling machine to pull the rails; the other is to install a rail alignment device on a large rail welding car. The former rail pulling The method is time-consuming and labor-intensive, and it is necessary to arrange manual rail pulling op...
