Subway train anti-climbing energy absorber

Abstract

The invention relates to a subway train anti-climbing energy absorber, and belongs to the technical field of a railway vehicle collision protective device. The subway train anti-climbing energy absorber comprises an installing anti-climbing tooth and an installing base, wherein the installing base is arranged on an underframe end beam. The installing base is connected with the anti-climbing tooth via energy absorbing pipes and guide rods, induced holes are evenly distributed in the energy absorbing pipes, guide holes allowing the guide rods to penetrate through are left in the installing base, and guide pipes are installed in the guide holes. One ends of the guide rods are fixedly connected to the anti-climbing tooth, and the other ends of the guide rods penetrate through the guide pipes installed on the installing base. The guide rods and the guide pipes are used for guiding, and then the guiding performance is good. Compared with a traditional carbon steel anti-climbing device, a lightweight design is conducted on the anti-climbing energy absorbing structure, the subway train anti-climbing energy absorber is installed and welded by aluminum profiles, therefore, the weight is light, production and machining are simple, different anti-climbing crushing force values can be acquired by adjusting relevant parameters of the profiles, and therefore good adaptability is achieved for the design.

Description

technical field [0001] The invention relates to an anti-climbing energy absorber for subway trains, belonging to the technical field of rail vehicle collision protection equipment. Background technique [0002] With the continuous progress and development of rail transit technology, the issue of collision safety, as an important part of modern vehicle design, has become a hot spot in the design and research of rail vehicles; Or the friction, fracture, buckling, creasing and other damage forms of the weak part of the head car body will dissipate the huge impact kinetic energy, so as to protect the life safety of the passengers and the integrity of the main structure of the rail vehicle to the greatest extent. At present, the anti-climbers of subway vehicles mostly adopt carbon steel structure. Although the anti-climbers are better in guiding and absorbing energy, they are heavy and costly.

AI Technical Summary

Problems solved by technology

At present, the anti-climbers of subway vehicles mostly adopt carbon steel structure. Although the guide energy absorption is better, the weight is heavy and the cost is high. If the anti-climber adopts non-carbon steel structure, the weight is lighter, but the guidance is poor.

[0003] After searching, it was found that the Chinese patent No. 201220561307.5 provides an anti-climbing energy-absorbing device for rail vehicles. The energy-absorbing body effectively absorbs the impact energy through the structure of the outer cover plate to protect the car body and personnel, but this The structure of the device is complicated, and the manufacturing cost is increased through the energy-absorbing materials with complex structure. At the same time, in order to achieve the design strength, heavy I-beams and steel plates are used, which increases the overall weight of the device.
