Parking method for two-way braking anti-rolling system on railway line

Abstract

The invention discloses a parking method for a two-way braking anti-rolling system on a railway line, and belongs to the field of railway safety anti-rolling parking facilities. According to the parking method for the two-way braking anti-rolling system, four anti-rolling devices and two square bars are included, and the four anti-rolling devices are two anti-forward-rolling devices and two anti-backward-rolling devices; the two anti-forward-rolling devices are arranged at the front part, and the two anti-backward-rolling devices are arranged at the rear part; the two ends of the square bars are fixedly connected with supports of the anti-rolling devices respectively, so that a rigid synchronous mechanism is formed. Each anti-rolling device further comprises a linear cylinder, an oscillating cylinder, an iron shoe, a supporting mechanism and an air path mechanism. By adopting the parking method for the two-way braking anti-rolling system on the railway line, the mechanical and pneumatic technologies are combined, the purposes that rigid synchronous two-way braking of two wheels on the two sides of a train is achieved, and the iron shoes will not damage steel rails and not be easily lost during fixation can be achieved, the service life is prolonged through the pneumatic technology, and the using operation risk is effectively lowered.

Description

[0001] The application of the present invention is a divisional application, the application number of the parent application: 2014106755560; the name of the parent application: a two-way braking anti-rolling system for railway lines; the application date of the parent application: November 21, 2014. technical field [0002] The invention belongs to the field of railway safety anti-rolling parking facilities, in particular to a parking method for a two-way brake anti-rolling system on a railway line. Background technique [0003] At present, most of the parking devices used on the railway line use the principle of two brake rails to clamp the wheel brakes. They have structural forms such as spring mechanical, electromagnetic, hydraulic and self-weight types. These parking devices all have the following defects: The braking force is generated by the friction after the brake rail and some wheels are squeezed. The braking force is not large enough, and the braking is not reliabl...

Problems solved by technology

[0007] Aiming at the problems existing in the prior art that the iron shoes for train braking can only brake one wheel in one direction, the braking of the two wheels is not synchronized, the iron shoes are easy to be lost, and the service life is not long, etc., the present invention provides a Two-way brake anti-rolling system on railway lines
