Novel laser rust removing device

Abstract

The invention discloses a novel laser rust removing device. The novel laser rust removing device comprises a laser rust remover and a hull wall-climbing carrying platform where the laser rust remover is placed. The hull wall-climbing carrying platform comprises two magnetic drive units, four belt tightness regulating mechanisms, a head cross beam, a middle cross beam, a tail cross beam, four flexible longitudinal ribs and an equipment carrying base. Through matching between the four flexible longitudinal ribs and the four belt tightness regulating mechanisms, the novel laser rust removing device can stretch, contract and bend freely within certain limits so as to be attached to the surface of a hull, and the equipment carrying base can be kept in the balanced posture. Thus, the laser rust remover can carry out the rust removing work in the steady posture and complete the hull rust removing work efficiently.

Description

technical field [0001] The invention relates to a laser rust removal device, in particular to a laser rust removal device for hull climbing walls of a flexible skeleton. Background technique [0002] At present, most of the devices used for ship maintenance and derusting operations use permanent magnet crawler adsorption technology. Most of these devices have rigid crawler structures and are difficult to achieve frequent curvature changes during movement. The force is not strong, and the traditional rust removal devices mostly use high-pressure water spray to remove rust, so there are three problems: First, when passing through the hull surface with large curvature, the effective contact area between the crawler and the hull surface is reduced, such as ships. For some parts with large curved surfaces such as the fore and aft parts, the bilge part, the track or driving wheel of the device cannot reach the minimum effective contact area required for normal operation with the s...

Problems solved by technology

[0002] At present, most of the devices used for ship maintenance and derusting work adopt permanent magnet crawler adsorption technology. Most of these devices have rigid crawler structures, and it is difficult to achieve frequent curvature changes during movement, and the attachment surface to the hull surface is small. Adsorption The force is not strong, and the traditional derusting device mostly adopts high-pressure water spray derusting method, so there are three problems: First, the effective contact area between the crawler and the hull surface is reduced when passing through the surface of the hull with a large curvature. Fore and stern, bilge and other parts with large curved surfaces, the track or driving wheel of the device cannot reach the minimum value of the effective bonding area required for normal work with the surface of the hull, thus reducing the adsorption force, causing the entire device to not move normally, or even A fall accident occurred; second, due to its relatively fixed track and internal structure, the equipment carried by the device cannot maintain a good working posture on the surface of the hull with different curvatures and large changes, which affects the quality of work

The third is that the high-pressure water spray derusting technology will produce flash rust during the derusting operation, and it cannot produce roughness, which has many limitations in actual operation
