Compression resistance cap in dangerous chemical transport vehicle energy-absorbing device

Abstract

The invention provides a compression resistance cap in a dangerous chemical transport vehicle energy-absorbing device. The compression resistance cap comprises a cone-shaped cap body which is of a hollow structure, all surfaces of the cap body are each provided with a protective layer, and the end face of the end, with a larger external diameter, of the cap body is a plane. The protective layers are zinc-plating layers or bead weld nickel alloy layers, the taper value of the cap body is 75+ / -5 degrees, the wall thickness of the cap body ranges from 3 mm to 4.5 mm, and the cap body is made of Q235 steel or Q236 steel. The inner wall of the cap body is provided with a reinforcing structure. According to the compression resistance cap in the dangerous chemical transport vehicle energy-absorbing device, the structural design is reasonable, and the assembled energy-absorbing device is good in overall energy-absorbing effect; the cone-shaped cap body is adopted, so that compared with the structure shaped like a rectangle and the like, the structural stability is good, and the compression requirement for an energy-absorbing tube during a collision can be better met. The protective layers are the zinc-plating layers or the bead weld nickel alloy layers, rusting of the cap body is effectively prevented, the friction coefficient of the surface of the cap body is increased, and therefore it is guaranteed that effective compression is conducted on the energy-absorbing tube in the collision process of the compression resistance cap.

Description

technical field [0001] The invention belongs to the technical field of vehicle-mounted anti-collision equipment, and in particular relates to an anti-pressure cap in an energy-absorbing device of a vehicle transporting hazardous chemicals. Background technique [0002] At present, the birth of automobiles has brought various conveniences to human life. At the same time, traffic accidents have increased continuously. Car accidents have also brought many shadows to human beings. Drivers and passengers desire more protection for people and vehicles when traveling. When a vehicle hits an obstacle ahead at a relatively high speed, the vehicle will receive a large impulse, resulting in a large obstacle acceleration that makes the vehicle drop from high speed to a standstill in an instant, and the original large kinetic energy is almost completely converted into the internal energy of the vehicle, making The vehicle was severely damaged and deformed, resulting in casualties of peop...
