Maintenance device outside bridge and using method thereof

Abstract

The invention discloses a maintenance device outside a bridge, the device comprises a shell plate and drive mechanisms, wherein the shell plate comprises a first half ring and a second half ring, oneend of the first half ring is rotationally connected with one end of the second half ring, and a bridge pier entrance is arranged between the other end of the first half ring and the other end of thesecond half ring. The inner sides of the first half ring and the second half ring are connected with installation ring plates, and a plurality of drive mechanisms are installed on opposite sides of the two installation ring plates. A plurality of paint spray nozzles spray paint to the bridge pier, and a spreading plate abuts with the outside of the bridge pier under the drive of a first hydrauliccolumn; as the shell plate moves outside the bridge pier, the spreading plate can spread the paint on the outside of the bridge pier. The paint spraying efficiency is improved, and the spraying is more full and uniform. Or the paint can be sprayed after cleaning, so the exterior of the bridge pier can be comprehensively maintained, and the aesthetics and durability of the bridge pier are improved.

Description

technical field [0001] The invention relates to a maintenance device, in particular to a bridge external maintenance device and a using method thereof, belonging to the field of bridge applications. 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 buildings that cross mountain streams, poor geology or meet other transportation needs to make traffic more convenient. Bridges generally consist of bridge decks and piers. In order to make the piers less prone to damage and have better durability during use, maintenance devices are often used to maintain the outside of the piers. [0003] But the maintenance device outside the existing bridge still has certain deficiencies in use. Existing external maintenance devices of bridges often use cleaning boats to clean...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a bridge external maintenance device and its use method, which can solve the problem that the existing bridge external maintenance devices often use cleaning boats to clean bridge piers, or use manual cleaning and maintenance of bridge piers

The external cleaning of the bridge piers is not thorough, the spray paint is uneven, and cannot be quickly maintained, and the bridge piers are prone to damage during use, which is a technical problem with relatively large limitations
