A turnout hook locker for rail transit

Abstract

The invention relates to the technical field of rail transportation, and discloses cross hooking lock setting for rail transportation. The cross hooking lock setting comprises a screw, wherein the exterior of the screw is sleeved with a locking nut through threads; a locking disc is fixedly mounted at the right end of the locking nut; a locking hole is formed in the front surface of the locking disc; a movable hook positioned on the right side of the locking disc is movably connected with the exterior of the screw in a sleeving manner; a locking block is fixedly mounted at the top of the leftside surface of the movable hook. Through the rotation of the locking nut, the locking nut pushes the locking disc to be adhered to the left side surface of the movable hook, rightward extrusion forceis provided for a ball, through the effect of power transmission of a fixed sleeve, an adjustable sleeve, a threaded rod and a movable groove, extrusion force is applied to the left end of an elasticsteel plate, the elastic steel plate is deformed by the force and hunched up, and powerful support force is provided for a stock rail, so that when a train passes a rail in which the cross hooking lock setting is arranged, the cross hooking lock setting cannot move up and down, the abrasion speed of the cross hooking lock setting is effectively reduced, and the road accessing safety of the trainis guaranteed.

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] Rail transit refers to a type of vehicle or transportation system that runs on a specific track. The most typical rail transit is composed of a train and a rail network. In order to enable the train to turn, there are many kinds of switches in the rail network, such as single When there is no interlocking automatic device at the turnout or the interlocking automatic device is in the state of maintenance for receiving and dispatching trains, it is necessary to use the turnout hook lock device to align the relevant locking devices on the access road Lock the turnout and the protective turnout on the adjacent line. The turnout hook lock can fasten the turnout close to the point rail and the basic rail together, or fix the repelling point rail at a certain position to lock the approach and ensure the safety of...

AI Technical Summary

Problems solved by technology

[0003] 1. There is a gap between the movable hook and the basic rail, and there is no object supporting the basic rail in the gap. When the train passes the track where the switch locker is located, the track will vibrate violently, causing the switch hook to move up and down. The lock causes wear and tear. Over time, the turnout hook lock wears seriously, resulting in a larger gap between the switch rail and the basic rail, which cannot guarantee the safety of the train approach

[0004] 2. During the up and down movement of the turnout hook locker, the contact area between the movable hook and the basic rail will become smaller, so that the friction between the movable hook and the basic rail will become smaller, resulting in the turnout hook locker under the action of the repulsive force of the sharp rail Moving along the direction of the track, there are cases where the switch hook locker falls off and the basic rail is separated from the switch rail, which cannot guarantee the safety of the incoming and outgoing trains.
