Turnout coupler lock device for rail transit

Abstract

The invention relates to the technical field of rail transit and discloses a turnout coupler lock device for rail transit. The device comprises a stock rail, a switch rail is arranged on one side of the stock rail; one side of the stock rail makes contact with one side of the switch rail, a movable connecting block is arranged on one side of the bottom end of the stock rail, a locking screw is movably connected into the movable connecting block in a sleeved mode, a connecting nut is arranged on one side of the outer surface of the locking screw, and the outer surface of the locking screw is inthreaded connection with the interior of the connecting nut. According to the invention, a fixed connecting plate and a clamping device are arranged; the stress points of the stock rail and the switch rail can be moved to the middle positions of the stock rail and the switch rail; therefore, the stock rail and the switch rail can be stably and effectively attached together, the problems that an existing hook lock device is only stressed at the bottom of the rail, and consequently the attaching tightness and stability of the top of the stock rail and the top of the switch rail are poor are solved, and the safety of a train in the rail changing process is effectively improved.

Description

technical field [0001] The invention relates to the technical field of rail traffic, in particular to a turnout hook locker for rail traffic. Background technique [0002] The track switch is an essential equipment for the train to transfer from one track to another track. It is an important part of rail transportation. It is combined, and the switch includes switch rails, basic rails and switch mechanisms. When the train is going to transfer from the A track to the B track, the switch mechanism is first manipulated to move the position of the switch rails, so that the switch rails 1 is close to the basic rail A, and the tip rail 2 is separated from the basic rail B, so that the train can transfer from the A track to the B track. [0003] And when it is necessary to change the track for a long time, it is necessary to use the switch hook locker to manually fix the point rail and the basic rail in the point switch tightly together, so as to prevent the train accident caused ...

AI Technical Summary

Problems solved by technology

[0006] The invention provides a turnout hook locker for rail transit, which has the advantages of firm locking, close fit between the basic rail and the switch rail, good safety and high stability, and solves the problem of the existing turnout hook locker being installed. During the process, the basic rail and the switch rail are clamped from the bottom of the track, so that the stress point of the basic rail and the switch rail is below it, and the tightness of the top of the basic rail and the switch rail is poor. The stability is low. When the train passes, the huge pressure and strong vibration are generated, and the position of the switch hook lock at the bottom of the track is shifted, and even the fracture and failure are caused by the excessive vibration, which leads to the basic The detachment of the rail and the switch rail, which in turn leads to the derailment of the train when switching tracks
