Description

Technical Field

[0001] This utility model relates to the field of grinding device technology, and in particular to a grinding device for ship repair. Background Technology

[0002] After a long voyage, the paint on a ship's deck is prone to damage or peeling due to exposure to sunlight, seawater erosion, collisions, and abrasion. To prevent rust from forming at the damaged or peeling areas, it is necessary to repair the damaged or peeling paint by spraying paint.

[0003] Currently, most paint repair methods involve manually applying a handheld spray gun to the surface of a ship. This often results in uneven paint application, requiring surface treatment. However, manual treatment is inefficient, and the quality of sanding varies, affecting the repair results. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a grinding device for ship repair.

One of the sliding blocks is threadedly connected to the outer surface of the threaded rotating rod, and the other sliding block is slidably connected to the outer surface of the guide rod.

[0008] As a further description of the above technical solution:

[0009] The surface of the first movable plate is provided with a first groove adapted to the movable column, and the surface of the second movable plate is provided with a second groove adapted to the movable column.

[0010] As a further description of the above technical solution:

[0011] The pushing assembly includes a first driving cylinder fixedly connected to the upper surface of the first movable plate. A pushing mounting strip is fixedly connected to the piston end of the first driving cylinder, and the pushing mounting strip is fixedly connected to the top end of the movable column.

[0012] As a further description of the above technical solution:

[0013] The grinding assembly includes a first connecting plate fixedly connected to the bottom end of the movable column, a second driving cylinder fixedly connected to the lower surface of the first connecting plate, a second connecting plate fixedly connected to the piston end of the second driving cylinder, a driving motor fixedly connected to the lower surface of the second connecting plate, and a grinding disc fixedly connected to the output shaft of the driving motor.

[0018] This utility model has the following beneficial effects:

[0019] Compared with existing technologies, this ship repair grinding device starts a servo motor. The output shaft of the servo motor rotates a threaded rotating rod, causing one of the sliding blocks to move on the outer surface of the threaded rotating rod. This causes two sliding blocks to move the first and second moving plates, thereby moving the grinding disc. The first drive cylinder is then activated. The piston end of the first drive cylinder moves a pushing mounting strip, which in turn moves a moving column, thus moving the grinding disc. This allows the grinding disc to perform grinding over a wider area, improving the grinding effect. Attached Figure Description

[0031] Working principle:

[0032] When in use, after the paint repair on the ship's surface is completed, the staff will carry the polishing device to the paint repair area using the portable handle and power it on.

[0033] Start the second drive cylinder 13.
