Anticollision energy absorption assembly for protecting tank body of hazardous chemicals transport vehicle

Abstract

The invention provides an anticollision energy absorption assembly for protecting a tank body of a hazardous chemicals transport vehicle. The anticollision energy absorption assembly includes a sealing mechanism and an anticollision mechanism, the sealing mechanism is installed at the left end of the anticollision mechanism, the sealing mechanism comprises a sealing door, an inflation tube, a sealing airbag, and a sealing membrane, the anticollision mechanism comprises a housing, a rubber cushion, a protection airbag, honeycomb explosion-proof blocks, telescopic rods, springs and an inner tankbody. Compared with the prior art, the anticollision energy absorption assembly has the following beneficial effects: inert gas is filled into the sealing airbag, so that the sealing membrane wraps and seals a liquid adding port in the inner tank body, at the same time, an inert gas isolation layer is produced, explosion is effectively prevented, in addition, the housing per se has a certain structural strength, and can play a good cushioning protection role in a slight impact, when subjected to violent impact, the springs and the inflated protection airbag effectively absorb the impact force, the energy absorption cushioning effect of the energy absorption device is ensured, and thus the vehicle safety is effectively ensured.

Description

technical field [0001] The invention relates to an anti-collision energy-absorbing component for protecting the tank body of a hazardous chemical transport vehicle, and belongs to the technical field of hazardous chemical transport vehicles. Background technique [0002] Hazardous chemicals are dangerous chemicals, which refer to chemicals that are flammable, explosive, toxic, harmful and radioactive, and are likely to cause casualties and property damage during transportation, loading, unloading and storage, and require special protection. When transporting chemicals, special dangerous chemical transport vehicles are often used for transportation. Due to some objective reasons, rear-end collision accidents occur frequently. When a collision accident occurs, the passive safety device on the vehicle becomes the last line of defense to protect the safety of the occupants. Collision buffer energy-absorbing structure is an important passive safety device. [0003] The existing ...

AI Technical Summary

Problems solved by technology

[0003] The existing anti-collision energy-absorbing components for protecting the tank of hazardous chemical transport vehicles cannot meet the protection requirements for the tank of hazardous chemical transport vehicles. In addition, the buffering and energy-absorbing effect is not satisfactory, and at the same time it is difficult to prevent the spread of flames, which can cause explosions. big security risk
