High-performance towing anti-collision device of road construction operation vehicle

Abstract

A high-performance towing anti-collision device of a road construction operation vehicle comprises an anti-collision frame, an upper cross beam, a lower cross beam, trundles, a baffle, a first supporting rod, a first connecting rod, a first connecting cylinder, a first spring, a buffer plate, a second supporting rod, a second connecting rod, a second damping base, a second connecting cylinder, a second spring, a supporting protruding block, a third damping rod and a traction structure. The anti-collision device is easy and convenient to use and flexible to use; the multi-stage pressure reduction structures of the device are in linkage fit, so that the device has high anti-collision performance; and local or complete maintenance can be carried out after collision.

Description

technical field [0001] The invention relates to the field of road construction, in particular to a high-performance trailer anti-collision device for a road construction vehicle. Background technique [0002] In the process of road construction, it is necessary to block and fence the road in the construction section to ensure the smooth construction of the construction site. 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, usually in the road construction area. Put some plastic traffic cones to encourage pedestrians to make early detours when crossing. The way of setting plastic traffic cones on the side of the construction area can only realize the warning function to pedestrians. When pedestrians in the surrounding roads have unexpected situations, such as drunk driving or inattention, which cause collisions with plastic traffic cones, the plastic traffic cones cannot be ...

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
