Description

Technical Field

[0001] The utility model relates to the technical field of shipbuilding, in particular to an anti-corrosion coating spraying mechanism for shipbuilding. Background Art

[0002] As a means of water transport, ships occupy an important position in the transportation industry. Since ships are always in the water, they are often corroded by environmental factors such as moisture and rain. Therefore, during the shipbuilding process, spraying equipment is needed to perform anti-corrosion spraying on various parts to improve their anti-corrosion performance. For example, a kind of anti-corrosion paint spraying device for shipbuilding disclosed in the China Patent Network (public announcement number CN213222950U) uses cylinder components to clamp and drive the clamp to clamp and fix the parts when performing anti-corrosion spraying on ship parts. Then, the rack is driven by the cylinder component to move so that the gear rotates the horizontal axis, driving the fixed parts to flip, and then the horizontal and vertical drive components are used to drive the spray gun to dynamically spray the rotating parts.

[0003] However, there are still some shortcomings in the above-mentioned patents and the anti-corrosion spraying devices for ship parts adopted in the existing market: the existing method of using a rotating clamping component to drive the ship parts to rotate, and then using a horizontal and lifting component to drive the spray gun to spray the ship parts for anti-corrosion, which drives the spray gun to move back and forth for spraying, has a relatively low spraying efficiency and takes a long time, and when facing the anti-corrosion spraying work of irregular parts, the back and forth displacement of the spray gun often cannot achieve uniform anti-corrosion spraying. To this end, a person skilled in the art provides an anti-corrosion coating spraying mechanism for ship construction to solve the problems raised in the above background technology.

[0009] As a further solution of the utility model: the upper half of the bracket of the lifting stand is provided with a track slide groove which guides the lifting arm.

[0010] As a further solution of the utility model: the rotating platform and the rotating pressing platform are perpendicular to each other and both the rotating platform and the rotating pressing platform are truncated table structures.

[0013] As a further solution of the utility model: a plurality of groups of the positioning electric push rods are arranged at equal intervals.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] When the utility model performs anti-corrosion spraying on ship parts, the ship parts to be sprayed are placed upright on a rotating table and fixed by a pressing positioning mechanism. After the ship parts are fixed by a pressing positioning mechanism, the overall horizontal displacement of the paint nozzle is adjusted by a translation electric push rod in the dynamic spraying mechanism, and the independent horizontal displacement of the paint nozzle is adjusted by a positioning electric push rod. The nozzle positions of the respective paint nozzles are doubly adjusted and positioned so that they maintain a suitable spacing with the ship parts in all directions.
