Description

Technical Field

[0001] This utility model relates to the field of grinding device technology, specifically a hull grinding device for ship painting and maintenance. Background Technology

[0002] Ship painting and maintenance is a crucial step in ensuring the structural safety, navigation performance, and extended service life of a ship. The removal of old coatings, rust, and marine organisms from the hull surface is the foundation of the painting operation and directly determines the adhesion and durability of subsequent coatings. Therefore, hull grinding equipment is one of the essential pieces of equipment in ship painting and maintenance.

[0003] Existing grinding devices have complex structures and unreasonable designs. During long-term use, the inner wall of the protective cover is prone to damage, requiring replacement. Since the protective cover is snapped onto the outside of the grinding head, the positioning block that snaps onto the protective cover is prone to wear during disassembly, making it impossible to insert a new protective cover. To address this problem, the inventor has designed a hull grinding device for ship painting maintenance. Utility Model Content

[0025] Please see Figures 1 to 4 The present invention provides an embodiment of a hull grinding device for ship painting and maintenance, which includes a pneumatic grinder 1, a protective cover 2, and a mounting component 3; the protective cover 2 is disposed on the top of the grinding head of the pneumatic grinder 1, and the mounting component 3 is disposed on the top of the protective cover 2.

[0026] The pneumatic grinder 1 is the core grinding tool. It removes rust or old coatings from the surface of the hull by rotating the grinding head at high speed. The protective cover 2 covers the top of the grinding head of the pneumatic grinder 1 to block the splashing impurities generated during grinding.

[0027] Mounting component 3 includes a positioning block 31, a support column 32, a connecting frame 33, and a limiting column 34. The positioning block 31 is fixed to the surface of the pneumatic grinder 1, and the protective cover 2 is clipped inside the positioning block 31. Two positioning blocks 31 form a group, and two groups are provided in total. The two groups of positioning blocks 31 are symmetrically distributed at both ends of the protective cover 2. The support column 32 is fixed to the surface of the protective cover 2, and the connecting frame 33 is fixed to the surface of the pneumatic grinder 1. The support column 32 is connected through the interior of the connecting frame 33, and the limiting column 34 is connected through the interior of both the support column 32 and the connecting frame 33.

[0028] The positioning block 31 holds the two ends of the protective cover 2 to ensure that the protective cover 2 is accurately positioned. The support column 32 enhances the stability of the protective cover 2 and allows it to be disassembled vertically. The connecting frame 33 is used to connect with the support column 32 so that the protective cover 2 can be installed in the desired position. The limiting column 34 is used to limit the support column 32 inside the connecting frame 33.

[0029] A guide plate 35 is fixed to the outer surface of the limiting post 34, and a fixing frame 36 is fixed to the surface of the connecting frame 33 at the end of the limiting post 34 away from the guide plate 35.

[0030] The guide plate 35 is used to facilitate changing the position of the limiting post 34, and the fixing frame 36 is used to support and install the spring 37;

[0031] A spring 37 is fixed inside the fixed frame 36, and a connecting plate 38 is provided on the top of the spring 37;

[0032] Spring 37 applies an upward elastic force to connecting plate 38, realizing the automatic reset of movable column 39. Connecting plate 38 facilitates changing the position of movable column 39.

[0033] A movable column 39 is fixed on the upper surface of the connecting plate 38, and the movable column 39 is connected through the interior of the limiting column 34;

[0034] The movable post 39 is used to restrict the limiting post 34 to the desired position;

[0035] A movable frame 391 is fixed to the surface of the connecting frame 33 near the guide plate 35.

[0036] The movable frame 391 is used for the movable plate 393 to move inside it, thereby maintaining the horizontal movement of the guide plate 35;

[0037] A limiting groove 392 is provided inside the end of the movable frame 391 away from the pneumatic grinder 1, and the limiting groove 392 is horizontally distributed inside the movable frame 391;

[0038] The limiting groove 392 is used for the limiting block 394 to move inside it;

[0039] A movable plate 393 is fixed to the lower surface of the guide plate 35. The bottom of the movable plate 393 is located inside the movable frame 391. A limit block 394 is fixed to the bottom surface of the movable plate 393. The limit block 394 is located inside the limit groove 392.

[0040] The movable plate 393 connects the guide plate 35 and the limiting block 394, transmitting the horizontal movement of the guide plate 35 to the limiting block 394. The limiting block 394 is used to restrict the movable plate 393 to move within the movable frame 391.

[0041] Working principle: When grinding is required, first start the pneumatic grinder 1, so that the grinding head of the pneumatic grinder 1 is in a high-speed rotating state, and move the grinding head to the rusty area for grinding. With the design of the protective cover 2, the movement range of splashed impurities is limited, which plays a role in protecting the user.

[0042] When the protective cover 2 needs to be replaced, a downward pressing force is applied to the connecting plate 38, causing the movable column 39 to disengage from the interior of the limiting column 34. Then, a pushing force is applied to the guide plate 35, causing the limiting column 34 to disengage from the interior of the connecting frame 33. After the limiting block 394 moves into the interior of the limiting groove 392, a pulling force is applied to the protective cover 2, causing the support column 32 to disengage from the interior of the connecting frame 33. The new support column 32 is then passed through the interior of the connecting frame 33, so that the top of the protective cover 2 is locked inside the positioning block 31. Then, a pressing force is applied to the connecting plate 38, causing the spring 37 to be in a compressed state. Then, a pushing force is applied to the guide plate 35, causing the movable plate 393 to move horizontally inside the movable frame 391, so that the guide plate 35 is in contact with the surface of the connecting frame 33. After that, the force applied to the connecting plate 38 is released, and under the elastic force of the spring 37, the movable column 39 springs back into the interior of the limiting column 34.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
