The utility model relates to the technical field of bridge engineering construction, in particular to a reinforcing mesh lowering device. The device comprises an upper disc, a lower disc, a connectingrod and a hoisting assembly. During work, the lifting device lifts the connecting rod; the upper disc and the transverse plate are tightly attached together through extrusion force and stably put down to a designated position; afterwards, the upper disc is lifted up, and then the connecting piece arranged between the upper disc and the transverse plate is loosened due to the effect of no tension,the second side of the transverse plate falls off, and the transverse plate is connected with the inclined plate, so that the inclined plate moves vertically and transversely, the lifting hook on theinclined plate falls off from the steel bar mesh, the steel bar mesh is hooped on the hole wall due to elastic deformation, and mesh hanging is completed. The reinforcing mesh lowering device provided by the utility model is simple in structure, convenient to disassemble, capable of being repeatedly used for multiple times and light in weight, manpower is saved, and the problems that the reinforcing mesh lowering efficiency is low, the safety is low, and time, labor and materials are consumed in a manual mode are solved.
