Anti-collision buffer device for highway engineering maintenance

The utility model discloses an anti-collision buffer device for highway engineering maintenance. The anti-collision buffer device comprises a fixed block and a baffle, adjusting grooves are horizontally formed in the four corners of the interior of the fixing block, damping springs are fixedly installed in the middles of the inner walls of the left sides of the adjusting grooves, the right ends ofthe damping springs are fixedly connected with the middles of the left sides of adjusting plates, and guide grooves are formed in the middles of the inner walls of the right sides of the adjusting grooves in a penetrating mode. When a vehicle collides with the baffle, the adjusting plate on the left side of the guide rod can be pushed to move leftwards in the adjusting groove to extrude the damping spring, and the damping spring can further absorb impact and vibration generated when the vehicle collides with the baffle; an inverted V-shaped damping plate is fixedly installed in the rubber block, when a vehicle collid
