Anti-creep device of rail vehicle

Abstract

The invention belongs to the technical field of vehicular equipment, and relates to an anti-creep device, in particular to an anti-creep device of a rail vehicle. The anti-creep device is fixed at the front end of the rail vehicle. The device is characterized by comprising a pair of mounting seats connected with draw bars on the two sides of the rail vehicle respectively, wherein the mounting seats are articulated with an anti-creeper by moving components; air springs are arranged at the bottoms of the draw bars; and a piston end of each air spring is fixed at one end, close to each mounting seat, of each moving component. According to the device, with the adoption of a reasonable structural design, the opening and closing of the anti-creep device can be realized, and the anti-creep device can keep a continuous opening trend after opened and a locking trend after closed. The device has the benefits that the anti-creep device is in a closed state generally to ensure the personal security; when under-vehicle operation is required to be performed, the anti-creep device is only required to be in an opened state to exert the function of expanding an under-vehicle operation space.

Description

technical field [0001] The invention relates to an anti-climbing device, in particular to an anti-climbing device for railcars, and belongs to the technical field of vehicle equipment. Background technique [0002] Low-floor trams are usually aesthetically pleasing, and the front end of the driver's cab is designed as a closed mechanism, which cannot meet the needs of increasing the operating space under the car, and the existing anti-climbing devices are all fixedly installed on the front end of the tram, for example, the application number is 201210459269.7, The Chinese invention patent application titled "An Anti-climbing Device" discloses an anti-climbing device fixedly installed at the front end of the car body chassis. Although the installation space is saved, because the anti-climbing device itself occupies a certain space, it still cannot Meet the needs of increasing the operating space under the car.
