Rear buffer device of engineering truck and anti-collision engineering truck

Abstract

The invention provides a rear buffer device of an engineering truck and the anti-collision engineering truck, and belongs to the technical field of vehicle engineering. The rear buffer device comprises a connecting frame, a buffer frame and a power support assembly. When the engineering truck runs, the power support assembly is started, the buffer frame is turned upwards by 90 degrees to be lifted, and the engineering truck can run conveniently; when the engineering truck is suspended and carries out construction, the power support assembly is closed, the buffer frame is turned downwards by 90degrees to fall down, the buffer frame is horizontally placed at the rear end of the engineering truck, and the engineering truck is prevented from being collided. The buffer frame can contract in the running direction of the engineering truck, when the engineering truck is paused and conducts construction and an a vehicle behind cannot brake in time to collide with the buffer frame, the buffer frame is stressed to contract in the collision direction to conduct buffering, so that the collision force of the vehicle is counteracted, and the engineering truck is effectively prevented from beingcollided; and a buffer space can be provided for the rear vehicle, so that major accidents of vehicle damage and casualty of the rear vehicle are avoided.

Description

technical field [0001] The invention belongs to the technical field of vehicle engineering, and more specifically relates to a rear buffer device of an engineering vehicle and an anti-collision engineering vehicle. Background technique [0002] Road construction, such as sweeping vehicles or watering vehicles or watering vehicles that need to temporarily stop on site during work or for some reason, especially when construction operations are carried out on the expressway expressway, the speed of the rear vehicles is very fast, and some drivers find the front construction vehicles At this time, it is easy to hit the construction vehicle due to untimely braking or other reasons, causing personal accidents to the personnel behind the vehicle. [0003] Although some construction vehicles are equipped with anti-collision devices at present, not only the anti-collision effect is poor, but also the volume is too large, which is very inconvenient to use.
