Problems solved by technology

[0009] However, the structure of the derailment protection strip is too complex and long, which will occupy too much space under the vehicle, which will affect the layout and installation of other under-vehicle equipment, and the protection strip needs to be welded to the Below the end beam, and the mounting seat is a box-shaped structure, which also has the disadvantages of complex structure and too large volume

Abstract

The invention discloses a derailment safety protective device which is shaped like an inverted L. The derailment safety protective device comprises a transverse part (1-1) and a longitudinal part (1-2) which is located below one side of the transverse part (1-1) and perpendicular to the transverse part (1-1). An installation seat formed by an outwards extending wing plate (1-3) is arranged at the two sides of the transverse part (1-1) in the width direction, and bolt holes (1-4) are formed in the installation seat; the inner side face of the longitudinal part (1-2) is a stopping face (1-6). The derailment safety protective device is simple in structure, small in size, light in weight, easy to install, maintain and replace, reasonable in structural design, stable and reliable in contact mode with a rail, stable and reliable in mechanical property during contact, and capable of remarkably improving the safety protective level of a vehicle.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a derailment safety protection device for rail vehicles. The invention also relates to a rail vehicle provided with the derailment safety protection device. Background technique [0002] At present, rail vehicle derailment accidents occur from time to time at home and abroad. Excessive lateral deviation after train derailment can easily cause vehicle rollover, which will cause major loss of life and property, especially on viaducts, which are limited by the width of the bridge deck. If the lateral movement is too large, the train may even fall into a river or a cliff, and the consequences will be more serious. [0003] The design purpose of the derailment safety protection device is to prevent accidents caused by excessive lateral movement of the wheels after the vehicle is derailed. [0004] The invention patent application with the publication number CN 101400559Y discl...
