Abstract

The invention relates to the field of steel structure bridges, and specifically discloses a steel structure bridge overhaul system, comprising a plurality of bridge decks and an overhaul vehicle. The bottom of the bridge deck is provided with a first horizontal guide rail through a first support rod; There is a first vertical through groove for the first support rod to pass through and a first circular groove for the first guide rail to pass through. The maintenance vehicle is also provided with a first horizontal groove, and the first horizontal groove is located in the first circular groove. The upper part is connected with the first circular groove and the first vertical through groove, the first horizontal groove is provided with a first push cylinder, the first push cylinder is provided with a first block, and the first block is provided with a A first installation space, a first travel wheel is arranged in the first installation space, and the first travel wheel can roll on the first guide rail. The purpose of the present invention is to solve the technical problem of how to facilitate maintenance.

Description

technical field [0001] The invention relates to the field of steel structure bridges, and specifically discloses a steel structure bridge maintenance system. Background technique [0002] Bridges are roads erected on rivers, railway lines, and highways for pedestrians or vehicles to pass through. Existing bridges generally use reinforced concrete structures. The reinforced concrete structures have the advantages of simple structure, low cost, long life, easy installation, maintenance and maintenance work It has the advantages of small quantity and so on, and has the widest application range. However, the construction time of reinforced concrete bridges is long and the cost is high, so steel structure bridges came into being. The construction period of the steel structure bridge is extremely short, the shortest only a few days, and the steel structure bridge has light weight, large span, good rigidity, weldability, very convenient installation, and can also be disassembled a...
