Automatic clearing and maintaining device which has adjustable operation speed and is used for bridge

Abstract

Disclosed is an automatic clearing and maintaining device which has adjustable operation speed and is used for a bridge. The bridge comprises a transverse main girder (4) provided with a guide rib (2) extending transversely, and auxiliary girders (41) supported on the transverse main girder (4). The automatic clearing and maintaining device comprises a support frame (99), a water supply pipe (61) supported on the support frame (99) and close to the main girder (4), and a nozzle (62) which is communicated with the water supply pipe (61) to be aligned with the part, needing to be cleared, of the bridge to spray water for clearing. The upper surface and the lower surface of the guide rib (2) are provided with a plurality of guide protrusions extending along the guide rib (2) respectively.

Description

technical field [0001] The application relates to the field of bridges, in particular to an automatic cleaning and maintenance device for bridges with adjustable running speed. 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...
