A road deflection detection device with active collision protection

Abstract

The application provides a road deflection detection device with active anti-collision protection, and belongs to the technical field of road detection. The road deflection detection device with active anti-collision protection comprises a handheld falling weight deflectometer, an anti-collision mechanism for preventing the force receiving structure from being impacted by the falling object is arranged above the bearing plate, and a protection mechanism is arranged above the bearing plate. Before the falling weight is about to fall, the distance between the two groups of threaded seats is increased by controlling the motor, the threaded seat movement drives the movement of the two groups of protection plates, the falling weight can pass between the two groups of protection plates, contact the force receiving structure, and when the falling weight does not need to fall, the two groups of protection plates can prevent the remaining falling objects from contacting the force receiving structure, thereby solving the problem that when the force receiving structure is not impacted by the falling weight, the upper part of the force receiving structure may be contacted by the falling object, the falling object generates a certain impact force, and the subsequent numerical analysis may be affected.
