The invention discloses a parking method of an anti-sliding device of a cargo train and belongs to the field of railway safety anti-sliding parking facilities. The anti-sliding device of the cargo train comprises an iron brake shoe and a supporting mechanism, and further comprises a linear cylinder, an oscillating cylinder and a gas circuit mechanism, wherein the supporting mechanism is fixed to the inner side of a steel rail; the linear cylinder is parallel to the steel rail and is fixedly connected with the supporting mechanism; the front end of a piston rod of the linear cylinder is fixedly connected with the rear end of the oscillating cylinder; the oscillating cylinder is slidably connected with the supporting mechanism; the iron brake shoe is connected with the front end of the oscillating cylinder in an oscillating mode; and the gas circuit mechanism is connected with the linear cylinder and the oscillating cylinder through gas guide pipes correspondingly. Through combination of the mechanical technology and the pneumatic technology, the purposes that mounting is easy and the iron brake shoe does not damage the steel rail and is not likely to be lost in the fixing process are achieved; the service life of the anti-sliding device is prolonged through the pneumatic technology, and the operation risk during using is effectively lowered.
Description
[0001] The application of the present invention is a divisional application, the application number of the parent application: 2014106753461; the name of the parent application: an anti-rolling device for freight trains; 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, and in particular relates to a parking method for a freight train anti-rolling device. 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 reliable enough. The passiv...
