A turnout hook locker for rail transit

Abstract

The invention relates to the technical field of rail transit, and discloses a turnout hook locker for rail transit, comprising a basic rail, one side of the basic rail is provided with a point rail, and one side of the basic rail is in contact with one side of the point rail , one side of the bottom end of the basic rail is provided with a movable connecting block, the inner part of the movable connecting block is movably sleeved with a locking screw, one side of the outer surface of the locking screw is provided with a connecting nut, and the locking screw The outer surface is connected with the inner thread of the coupling nut. The turnout hook locker for rail transit can move the stress point of the basic rail and the switch rail to the middle position through the setting of the fixed connecting plate and the clamping device, so that the basic rail and the switch rail can be stably and effectively attached to each other. Together, it solves the problem that the existing hook locker only bears force at the bottom of the track, which leads to poor tightness and low stability of the top of the basic rail and the switch rail, and effectively improves the quality of the train. Safety when changing tracks.

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
