Rigid train front end anticreeper

Abstract

The invention relates to a rigid train front end anticreeper which comprises a draw gear box and an anti-creep device which are arranged on the back of an end beam. A through hole for the anti-creep device to pass through is formed on the end beam. The anti-creep device comprises anti-creep teeth, a supporting base and a base, wherein the anti-creep teeth, the supporting base and the base are sequentially connected. The rear portion of the base of the anti-creep device penetrates through the through hole and then is connected on the draw gear box, and is fixed with the end beam through fasteners. Because the anticreeper is of a rigid structure and free of a bumper, and the base and the draw gear box are connected in a welding mode, the anticreeper is strong in rigidity and can not easily deflect under impact. Furthermore, the anti-creep device is connected with the end beam through bolts, the anticrepper is easy to replace in the real use process.

Description

technical field [0001] The invention relates to a train anti-climbing device, in particular to a rigid anti-climbing device arranged at the front end of a train. Background technique [0002] With the continuous progress and development of rail transit technology, the collision safety issue, as an important part of modern vehicle design, has become a hot spot in the research of rail vehicle design. [0003] According to the inventor's understanding, in the past train collision accidents, passive safety was rarely considered, especially the climbing accident, which would bring very serious consequences. For example, the Chinese patent with the authorized announcement of CN 202243517 discloses an anti-climbing device. The inventor found in a large number of tests on the anti-climbing device that although the use of this anti-climbing device can reduce the possibility of train climbing after a collision to a certain extent To reduce the damage caused by the collision accident....

AI Technical Summary

Problems solved by technology

However, because its structural rigidity is not strong, it is difficult to ensure that it will not be skewed under the impact force under complex and changeable collision conditions (that is, it does not stand straight toward the forward direction of the train, but bends toward the sides of the train or up and down). , when it is skewed, it cannot provide a good anti-climbing function

[0004] Moreover, the existing front end of the train is easily deformed under impact, and the structural strength is not enough
