Automatic sandblasting and derusting device between wing walls

Abstract

The invention discloses an automatic sandblasting and derusting device between wing walls. The automatic sandblasting and derusting device is characterized in that the sandblasting and derusting device consists of a body frame, a sandblasting machine, a sandblasting trolley and a lifter, wherein the body frame is in a frame structure formed by welding an upright post on a base with a transverse strut; a track and an arm brace are arranged on one side of the body frame; the track is fixedly arranged on the transverse strut and is parallel to the body frame; the arm brace is fixedly arranged on the upright post and is vertical to the upright post; the lifter is fixedly arranged on the base on one side of the body frame; the sandblasting trolley is a movable sandblasting gun arranged on the track; the movable sandblasting gun is connected with the sandblasting machine through a hose; the upper and the lower ends of the sandblasting trolley are connected with the lifter through wire cables; and the wire cables are arranged on the body frame through pulley wheels. Compared with the prior art, the automatic sandblasting and derusting device between wing walls has the advantages of being high in production efficiency and low in labor intensity, thereby efficiently avoiding the influence of dust to the health of people, being capable of saving about one-third sandblasting labor and reducing more than 60% of scaffold building work.

Description

technical field [0001] The invention relates to the technical field of ship spraying equipment, in particular to an automatic sandblasting and derusting device in a dock. Background technique [0002] The painting of ships is a relatively heavy process in the whole shipbuilding process, especially the secondary painting of ships is usually carried out in sections of the hull. Rust removal is the first task before coating construction. The purpose of rust removal is to make the The surface of the object to be coated meets the requirements of cleanliness and roughness, increases the adhesion between the coating and the surface of the object to be coated, and gives full play to the anti-corrosion performance of the coating, thereby prolonging the service life of the ship. Only by carrying out good surface pretreatment on the steel can the coating achieve the predetermined protective effect. [0003] At present, the derusting operation in domestic ship repair yards generally ad...

AI Technical Summary

Problems solved by technology

When the corrosion area is large, in order to shorten the occupation time of the dock, 100-200 workers are required to work in the dock at the same time. Scaffolding is also needed to facilitate the operation of the workers during sand blasting and derusting, which consumes a lot of man-hours and low operating efficiency. The environment is extremely harsh, and the dust is large, which affects the health of workers and pollutes the environment
