Anti-collision vehicle for high-speed maintenance

Abstract

The invention relates to an anti-collision vehicle for high-speed maintenance. The anti-collision vehicle comprises a vehicle body, an open rear carriage, an anti-collision bag, a hydraulic oil cylinder and a fixing rod. The open type rear carriage is arranged at the rear end of the vehicle body; the fixed rod is arranged on the open type rear carriage; a fixed plate is arranged at the rear end ofthe vehicle body; the hydraulic oil cylinder comprises an upper hydraulic oil cylinder and a lower hydraulic oil cylinder; the tail end of the lower hydraulic oil cylinder is fixedly connected with the fixed plate; the anti-collision bag comprises an upper anti-collision bag and a lower anti-collision bag; the extending end of the upper hydraulic oil cylinder is connected with the upper anti-collision bag; and the lower anti-collision bag is connected with the fixed rod. By means of the anti-collision bag, it can be guaranteed that even if a maintenance vehicle collides at a high speed, the collision force can be relieved through the anti-collision bag, the area, occupied by the anti-collision bag, of a compartment can be reduced through the design of the upper anti-collision bag and thelower anti-collision bag, and through the self-locking device on the fixing rod, when not in use, the anti-collision bag can be kept stable and does not shake or fall off, and the practicability is high.

Description

technical field [0001] The invention relates to the field of anti-collision vehicles, in particular to an anti-collision vehicle for high-speed maintenance. Background technique [0002] In the prior art, when there is an emergency on the expressway, such as a car accident, road damage, etc., vehicles and personnel are required to carry out maintenance. In the existing maintenance process, most special vehicles are used to warn behind the work area, but this The safety factor of this method is not high, and for the road condition of high speed, it cannot guarantee safety very well. Therefore, need a kind of safety factor height, the anti-collision car that is used for high-speed maintenance with strong practicability. Contents of the invention [0003] The problem to be solved by the present invention is to provide an anti-collision vehicle for high-speed maintenance with high safety factor and strong practicability. [0004] In order to ensure a high safety factor and s...
