Ship rust removal device

Abstract

The invention discloses a ship rust removal device which comprises a wall climbing trolley, a connecting mechanism and a spray head mechanism. The wall-climbing trolley comprises a base, electromagnetic wheels arranged on the lower portion of the base and an electric box arranged on the upper portion of the base. A limiting connecting piece is arranged on the outer side of the electric box. The connecting structure comprises a horizontal shaft, a first connecting block, a vertical shaft and a second connecting block, the horizontal shaft is fixedly arranged on the limiting connecting piece andpenetrates through the first connecting block, and a first adjusting knob is arranged on the first connecting block; the upper part of the vertical shaft is fixedly arranged on the first connecting block, and a second adjusting knob is arranged on the second connecting block; the spray head mechanism comprises a spray nozzle frame, a plurality of spray heads and connectors connected with the spray heads, the spray nozzle frame is further fixedly connected with a movable handle, one end of the movable handle penetrates through the second connecting block, and a third adjusting knob is arrangedon the second connecting block. The ship rust removal device is high in adaptability to the wall surface of a ship, high in adsorption capacity and capable of flexibly adapting to complex conditionsof the surface of the ship.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a ship derusting device. Background technique [0002] Ship rust removal is especially important in the ship repair industry. The existing rust removal methods mainly include manual rust removal, chemical rust removal and mechanical rust removal. Manual rust removal has high labor intensity, low rust removal efficiency, and difficulty in removing scale and other dirt. It is mainly used in the repair of local defects, as well as in difficult areas such as small cabins, corners and edges on the opposite side of steel; chemical derusting can only be operated in the workshop; there are many tools and processes for mechanical derusting, and the best derusting The method is high-pressure water jet derusting, that is, the impact of high-pressure water jet and the action of water prying are used to destroy the corrosion and the adhesion of the coating to the steel plate to achieve high-qua...

[0002] Ship rust removal is especially important in the ship repair industry. The existing rust removal methods mainly include manual rust removal, chemical rust removal and mechanical rust removal. Manual rust removal has high labor intensity, low rust removal efficiency, and difficulty in removing scale and other dirt. It is mainly used in the repair of local defects, as well as in difficult areas such as small cabins, corners and edges on the opposite side of steel; chemical derusting can only be operated in the workshop; there are many tools and processes for mechanical derusting, and the best derusting The method is high-pressure water jet derusting, that is, using the impact of high-pressure water jet and water prying action to destroy the corrosion and the adhesion of the coating to the steel plate to achieve high-quality surface treatment quality

[0003] The high-pressure water jet ship rust removal device in the prior art has the disadvantages of poor adaptability to the ship wall, weak adsorption capacity, complex structure, and low degree of automation. As a result, the device cannot be flexibly adapted to the ship during the ship rust removal process. Due to the complex surface conditions, it is easy to fall or overturn when encountering obstacles such as mesh plates or holes, and it is difficult to adjust the angle between the water jet beam and the surface of the ship according to the actual working conditions
