Road engineering protection device

The utility model discloses a road engineering protection device which comprises a spring, a bonding block, an anti-collision plate, an air guide groove, a mounting groove, a buffer pad, an electromagnetic chuck, a pressing switch, an electric push rod, an inductive switch, a collecting frame, a connecting column and a knocking device. Repeated installation of the anti-collision plate is avoided, and work is increased; through an electromagnetic chuck, a pressing switch, an electric push rod and an inductive switch, a collecting frame exceeds the inductive switch when an anti-collision plate is strongly impacted, so that the anti-collision plate can move backwards all the time, a connecting column is released, a spring is released, and the electromagnetic chuck is opened to fall into the collecting frame to be prevented from being damaged; and the anti-collision plate can fall off more smoothly through the knocking device. 本实用新型公开了一种道路工程防护装置，包括弹簧、粘结块、防撞板、导风槽、安装槽、缓冲垫、电磁吸盘、按压开关、电推杆、感应开关、收集框、连接柱和敲击装置，通过弹簧、粘结块、防撞
