A self-propelled retractable temporary bridge

Abstract

The invention discloses a self-propelled retractable temporary overpass, and belongs to the field of road traffic facilities. The self-propelled retractable temporary overpass is composed of lifting platforms, an overpass body, a supporting hydraulic cylinder, a supporting frame and wheels. The lifting platforms at the two ends of the overpass and the parts below the lifting platforms each have the same structures, and the structures are distributed symmetrically. When the temporary overpass is not used, the overpass body can be shortened, overpass stairs can be put on the lifting platforms, the overall length can be reduced, the space is saved, and the whole temporary overpass is conveyed conveniently. Before the temporary overpass is mounted, an overpass panel is in a folded state; whenthe temporary overpass is mounted, operation needs to be conducted simultaneously by two persons, one overpass stair is put down at one end of the mounting position, then one of the two persons fix one end of the overpass, the other person drags the other end of the overpass until the whole overpass body is unfolded fully, the other overpass stair is dismounted, at the same time a hydraulic pump is started to make the supporting hydraulic cylinder enter into a working state, and after the overpass body rises to the rated height, pedestrians can climb through the overpass stairs to the overpassand walk to the other side of a road.

[0002] With the development of society and the increase of urban population, the number of private cars also increases, which brings a great burden to urban roads. Traffic congestion is the norm, especially during holidays and commuting hours, which puts pressure on the traffic police Very large, in the prior art, in order to solve the conflict between pedestrians crossing the road and vehicles running on the road, overpasses have already appeared in the bustling areas of many cities, but most of the existing overpasses are fixed. To build roads, the overpass must be demolished, which will cause a lot of waste. If the new overpass is not built in time, it will bring big problems to traffic, and it will not be able to solve the road congestion well.
