Railway vehicle and head vehicle barrier-removing device thereof

Abstract

The invention provides a railway vehicle and a head vehicle barrier-removing device thereof. The head vehicle barrier-removing device comprises a flow guide plate, a front end framework and longitudinal beams, the front end framework is mounted at the front end of the inner side surface of the flow guide plate, the longitudinal beams are disposed on two sides of the inner side surface of the flow guide plate, two ends of the front end framework are connected with the longitudinal beams on the two sides respectively, and the rigidity of connecting positions between the longitudinal beams and the front end framework is smaller than that of any position of the longitudinal beams and the front end framework. When barriers are cleaned or train collision occurs, if the collision force that is exerted on the barrier-removing device exceeds the maximum load value that the barrier-removing device can tolerate, large extruding deformation can occur at the connecting positions between the front end framework and the longitudinal beams, the front end of the flow guide plate can gradually backwards retract, then space is provided for an energy absorption part that is mounted at the front end of a head vehicle so that the energy absorption part can effectively absorb collision energy, finally, the vehicle passive safety is improved, and severe safety accidents such as vehicle climbing or derailing can be avoided.

Description

technical field [0001] The invention relates to the technical field of vehicle safety, in particular to a rail vehicle and an obstacle removal device for a leading vehicle thereof. Background technique [0002] At present, with the gradual increase in the operating speed of rail vehicles, more and more attention has been paid to the passive safety design of trains. Wherein, in order to ensure the normal driving safety of trains, obstacle removal devices are often arranged at the bottom of the front end of fast trains such as high-speed EMUs to remove obstacles on the track. [0003] At present, in the traditional design process of obstacle removal devices, only the ability to remove obstacles on the track surface is often considered. There are clear requirements, but the upper limit requirements are not clear. However, when the track obstacles are too large or two trains collide, if the stiffness of the obstacle removal device at the front end of the rail vehicle head car ...

AI Technical Summary

Problems solved by technology

[0004] Therefore, how to design a head car obstacle removal device for rail vehicles to improve the safety of train operation and avoid the risks of climbing and derailment caused by the obstruction of the obstacle removal device and the inability to effectively absorb the impact energy caused by a collision accident is an important issue. Technical problems that technical personnel in the field need to solve urgently
