Rail overturning device

Abstract

The invention provides an anti-rolling device for rails, which includes a base, a clamping part and a lifting part, the clamping part has two oppositely arranged tong arms, a slideway is arranged on each tong arm, and the two described The pliers arm is hinged on the base, the lifting part is connected to the clamping part through a connecting piece, the lifting part can drive the connecting piece to slide in the slideway, and slide on the connecting piece When the first position of the slideway is reached, the two tong arms can clamp the steel rail; when the connecting piece slides to the second position of the slideway, the two tong arms can release the steel rail. The rail anti-turnover device of the invention can conveniently, quickly and efficiently realize the loading and unloading operation of the rail, and can effectively prevent the rail from rolling over during the loading and unloading process, thereby ensuring the safety of operators.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to an anti-overturning device for rails. Background technique [0002] When laying steel rails on national railways and subways, it is necessary to unload the steel rails from the long rail transport train set to the ground. There is a certain height difference when the rail is unloaded from a high place to the ground, and due to the uneven ballast and sleepers, the rail is easily tipped over during the unloading process. In addition, the rails of subway transportation are usually 100 meters long, and the rails of national railway lines are usually 500 meters long. After the rails are overturned, a lot of manpower is required to straighten them. Here comes the security risk. [0003] The existing rail anti-turnover device adopts the bottom clamping method, which is provided with a protrusion at the bottom, and needs two people to cooperate to make it locked on the bottom of t...

AI Technical Summary

Problems solved by technology

The anti-turnover device is time-consuming and labor-intensive when locked, and it is not easy to take out after locking, especially when the bottom of the rail is flat, it is more laborious to take out than when the bottom is ballast; Poor stability on track or flat ground, limited anti-rollover effect

In addition, the anti-turnover device needs to be fastened before the rail falls to the ground. Since the operation of the rail is continuous, it is more dangerous to install an anti-turnover device on the moving rail.
