Multi-stage anti-collision buffering device applied to road construction vehicle

Abstract

The multistage anti-collision buffering device comprises a horizontally-arranged vehicle body, an anti-collision box is installed at the position, close to the bottom, of the right side of the vehicle body, an opening is formed in the right side of the anti-collision box, an arc-shaped anti-collision plate is arranged in an inner cavity of the anti-collision box, and a fixing block is fixedly connected to the position, close to the top, of the left side of the arc-shaped anti-collision plate; through mutual cooperation of a trigger, a connecting block, a warning air bag, an air conveying pipe, a sealing sleeve, an electric telescopic rod and other components, when the anti-collision device is impacted, an arc-shaped anti-collision plate moves leftwards to make contact with the trigger, the trigger starts the electric telescopic rod, and the electric telescopic rod is driven to move leftwards to make contact with the arc-shaped anti-collision plate to make contact with the arc-shaped anti-collision plate to make contact with the arc-shaped anti-collision plate. The electric telescopic rod ascends and descends in the inner cavity of the sealing sleeve, air is compressed, the warning air bag is inflated through the air conveying pipe, the warning air bag is bounced off, and a vehicle far away from a road is warned.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a multi-stage anti-collision buffer device applied to road construction vehicles. Background technique [0002] Road construction vehicle refers to the whole process of planning, design, construction, maintenance and management with roads as the object and the engineering vehicle body it is engaged in. However, due to the slow speed of the road construction vehicle, the road construction vehicle is easy to A rear-end accident occurred. [0003] Therefore, the operator will add an anti-collision bumper on the rear side of the road construction vehicle to protect the road construction vehicle, but the existing anti-collision bumper can only realize one-time protection of the rear side of the vehicle body, and cannot meet the multi-level requirements. crash. Contents of the invention [0004] In order to achieve the above object, the present invention provides the foll...

[0002] Road construction vehicle refers to the whole process of planning, design, construction, maintenance and management with roads as the object and the engineering vehicle body it is engaged in. However, due to the slow speed of the road construction vehicle, the road construction vehicle is easy to rear-end accident

[0003] Therefore, the operator will add an anti-collision bumper on the rear side of the road construction vehicle to protect the road construction vehicle, but the existing anti-collision bumper can only realize one-time protection of the rear side of the vehicle body, and cannot meet the multi-level requirements. collide
