An automatic cleaning and maintenance device with improved service life and used for bridges

Abstract

The invention provides an automatic bridge cleaning and maintenance device capable of prolonging the service life. A bridge comprises a transverse girder (4) provided with a guide rib (2) transversely extending and an auxiliary beam (41) supported on the transverse girder (4). The automatic bridge cleaning and maintenance device comprises a supporting frame (99), a water supply pipe (61) supported on the supporting frame (99) and close to the girder (4) and a spray nozzle (61) communicated with the water supply pipe (61) and used for spraying water to the portion, required to be cleaned, of the bridge to clean the portion. The upper surface and the lower surface of the guide rib (2) are each provided with a plurality of guide protrusions stretching along the guide rib (2).

Description

technical field [0001] The application relates to the field of bridges, in particular to an automatic cleaning and maintenance device for bridges with improved service life. Background technique [0002] Bridges often have various truss girder structures. Due to the complex structure of the overall connection parts of this structure, dust and other dirt are easy to accumulate at the local connection positions. This is likely to have adverse effects such as corrosion on the connection parts of the beam structure, thereby causing potential risks to the overall safety and stability of the bridge structure. [0003] However, some existing cleaning and maintenance devices often need to be manually carried out, which causes the danger of the operation and the increase of the maintenance cost. However, some mechanical devices that can automatically realize cleaning and maintenance are complex in structure and high in cost. Contents of the invention [0004] The object of the pr...
