A turnout structure for urban rail transit

Abstract

The invention discloses a turnout structure for urban rail transit, which comprises a plurality of sleepers, two fixed rails are installed between the plurality of sleepers, and a plurality of corresponding sleepers are installed between the two fixed rails and the corresponding sleepers. In the connection mechanism, two moving rails are slidingly connected between the plurality of sleepers. The advantage is that the present invention can use the pressure exerted by the wheels on the moving plate during the driving process of the vehicle to automatically complete the extrusion operation of the extrusion air bag when the switch is used to switch the vehicle, so that the vehicle can be lifted. The stones are blown down without manual control, and the degree of automation is high, which can avoid the problem of wear when the stones fall into the gap between the fixed rail and the moving rail and cause the two to reset. To a certain extent, the service life of the switch can be improved, and it can avoid Due to the high hardness of the stone, there is still a certain gap between the fixed rail and the moving rail after reset, so as to ensure that the turnout can be used normally.

Description

technical field [0001] The invention relates to the technical field of urban rail transit, in particular to a turnout structure for urban rail transit. Background technique [0002] Urban rail transit is a vehicle transportation system that uses track structure for load-bearing and guidance. It mainly includes subway system, light rail system, monorail system, maglev system and automatic guided rail system. Turnout is a common facility in urban rail transit. Make locomotive Vehicles are transferred from one track to another, which can give full play to the passing ability of the line. It is mainly composed of sleepers, fixed rails, moving rails and bifurcated rails. [0003] When the turnout transfers the vehicle, the fixed rail and the moving rail will move accordingly, and the vehicle will be transferred from one track to another through the gap between the two tracks. It will drive the surrounding air flow to change. At this time, the stones on the road will fall into t...

AI Technical Summary

Problems solved by technology

[0003] When the turnout performs the rail switching operation on the vehicle, there will be a corresponding movement between the fixed rail and the moving rail, and the vehicle will be transferred from one track to another through the gap between the two. It will drive the airflow around it to change. At this time, the stones on the road surface will fall into the gap between the fixed rail and the moving rail under the action of the airflow. When the two are closed again, these stones will cause wear to the two, thereby reducing The service life of the turnout, and when the hardness of the stone is high, it may even cause the fixed rail and the moving rail to fail to reset and fit, resulting in poor use or complete failure of the turnout
