Quick self-adaptive supporting device for small-tonnage bridge

Abstract

The invention discloses a rapid self-adaptive supporting device for a small-tonnage bridge, belongs to the technical field of bridge reinforcement, and solves the problems that a currently used bridge supporting device cannot be quickly supported and assembled mainly through splicing and assembling arrangement, and a supporting device capable of being automatically unfolded through a shear fork mechanism and the like can only be applied to a planar bridge structure. The rapid self-adaptive supporting device for a small-tonnage bridge comprises a bottom plate, a pressurizing device and a reinforcing device; bottom pad bases are fixedly arranged on the two sides of the top of the bottom plate correspondingly. The top of each bottom pad base is connected with a middle pad base; the top of each middle pad base is connected with a top pad base; the top of each top pad base is connected with a top plate; a fixing base and a sliding frame plate are arranged, so that self-adaptive supportingon the supporting device is realized, the fixing base and the sliding frame plate can be unfolded in a vertical or low-angle movable mode according to the shape of the bottom face of a bridge so thatthe bridge can be assembled in a self-adaptive mode.

Description

technical field [0001] The invention relates to the technical field of bridge reinforcement, in particular to a fast and self-adaptive support device for small-tonnage bridges. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to cross mountains, poor geology, or meet other traffic needs to make traffic more convenient. The buildings and bridges are generally composed of superstructure, substructure, bearings and auxiliary structures. [0003] After retrieval, for example, the patent No. CN108774957B discloses a support structure for bridge reinforcement, including a base plate, a reinforcement device, and a first support plate and a second support plate that are flexibly connected in an X shape. The left and right sides of the upper end of the base plate are r...

Problems solved by technology

[0007] The purpose of the present invention is to provide a fast and self-adaptive support device for small-tonnage bridges, to solve the problem that the currently used bridge support devices proposed in the above-mentioned background technology are mainly set by splicing and assembling, and cannot support and assemble quickly. Support devices that can be self-expanded by means of fork mechanisms can only be applied to plane bridge structures, and are not suitable for supporting bridges with inclined bottom surfaces.
