A TUNNEL DEFORMATION DETECTION AND EARLY WARNING DEVICE FOR TUNNEL PROTECTION

The application discloses a tunnel deformation detection and early warning device for tunnel protection, which relates to the technical field of tunnel detection equipment. The application comprises a first arc arch frame, one side of the first arc arch frame is provided with an arc track, the internal sliding of the arc track is connected with a guide slide block, one end of the guide slide block is hinged with a L-shaped mounting plate, and the top of the L-shaped mounting plate is provided with a lifting chute. In this application, the L-shaped mounting plate is driven by starting the driving component to drive the collision roller to move along the top of the tunnel, so that when deformation occurs inside the tunnel, the extrusion collision roller will push the mounting base to move along the length direction of the lifting chute, and the mounting base will drive the infrared transmitter away from the original infrared signal launching track. Thus, the infrared receiver transmits abnormal signals to the controller through the change of the received signal, so as to warn the vehicles and personnel traveling inside the tunnel through the controller warning component.
