A high-performance trailer collision avoidance device for road construction vehicles

Abstract

A high-performance trailing anti-collision device for road construction vehicles, comprising an anti-collision frame, an upper beam, a lower beam, casters, a baffle, a first support rod, a first connecting rod, a first connecting cylinder, a first spring, A buffer plate, a second support rod, a second connecting rod, a second shock-absorbing seat, a second connecting cylinder, a second spring, a support bump, a third shock-absorbing rod, and a traction structure. The anti-collision device of the present invention has simple and convenient use steps and flexible use; the multi-stage decompression structures of the device are linked and cooperated to have strong anti-collision performance; partial or complete maintenance can be performed after impact.

Description

technical field [0001] The invention relates to the field of road construction, in particular to a high-performance trailer-hung anti-collision device for road construction vehicles. Background technique [0002] In the process of road construction, it is necessary to block the roads in the construction section to ensure the smooth construction of the construction section. At the same time, in order to meet the safety of the construction process, it is necessary to remind the surrounding pedestrians and vehicles to avoid them, usually placed in the road construction area. Put some plastic traffic cones to encourage early detours when pedestrians cross. The way of setting up plastic traffic cones on the side of the construction area can only serve as a warning to pedestrians. When pedestrians in the surrounding road section encounter unexpected situations, such as drunk driving or inattention, they collide with the plastic traffic cones. Provide good protection measures, pla...

AI Technical Summary

Problems solved by technology

The anti-collision device in the prior art is usually arranged at the rear end of the anti-collision vehicle, and the protective device is lifted and lowered through the lifting hinge, so that the working state of the anti-collision device can be switched, and the process of function switching is not easy; at the same time, the anti-collision device is usually It is a first-level or second-level anti-collision structure, and the anti-collision performance of the anti-collision structure is usually a rigid connection. When the impacting object hits, it will generate a large impact on the anti-collision device and the impacting object, and the anti-collision performance is weak. , and the safety performance of anti-collision is low; after the anti-collision device receives the impact force, all parts will lead to connection failure, which cannot be reused, the maintenance cost is high, and the economy is low
