Trailer anti-collision device applied to road construction work vehicle and road construction work vehicle

Abstract

The application relates to the field of road construction, in particular to a road construction operating vehicle and a trailer anti-collision device thereof. The trailer anti-collision device comprises an anti-collision rack which consists of a first support and a second support; a first-stage anti-collision unit is arranged at the outer side of the first support, a second-stage anti-collision unit and a third-stage anti-collision unit are arranged between the first support and the second support, one end of the second-stage anti-collision unit is connected to the inner side of the first support and the other end of the second-stage anti-collision unit is connected to the inner side of the second support, and the third-stage anti-collision device is arranged on the second-stage anti-collision device. The trailer anti-collision device and the road construction operating vehicle can improve anti-collision efficiency of the road construction operating vehicle greatly.

Description

【Technical field】 [0001] The present application relates to the field of road construction, in particular to a trailer anti-collision device applied to a road construction vehicle and a road construction vehicle. 【Background technique】 [0002] In order to prevent rear-end collisions of running vehicles at the rear, the existing road construction vehicle generally follows an anti-collision buffer vehicle during its construction work to ensure that the road construction vehicle will not be accidentally hit by an out-of-control vehicle traveling on the road. The rear of the anti-collision buffer vehicle is equipped with an anti-collision device. The anti-collision device includes a retractable yellow buffer pad and a lifting hinged frame. When the road construction vehicle is working, the yellow buffer pad on the anti-collision buffer vehicle passes through the lifting hinged frame Lay it down to protect the road construction vehicle, and after construction, the yellow bumper ...
