Description

Technical Field

[0001] This utility model relates to the field of ship steel structure grinding technology, specifically a ship steel structure grinding device. Background Technology

[0002] Ship steel structure refers to the hull structure made of high-strength steel, which is the main supporting and structural part of a ship. It is mainly composed of plates and a frame, which are connected together by welding, riveting and other methods to form the main frame and outer shell of the hull. Grinding is an important task in the shipbuilding and maintenance process, which aims to remove dirt, rust and old coatings from the surface of the steel structure, improve the surface quality, and lay the foundation for subsequent painting or welding operations.

[0003] Referring to the patent application CN210938537U, a ship steel structure grinding device is disclosed. A lifting box is fixedly connected to the left side of the top of a fixed base plate. A track plate is fixedly connected to the right side of the lifting box, located on top of the fixed base plate. A track groove is formed in the middle of the track plate, and a sliding plate is slidably connected inside the track groove. A first threaded cylinder is fixedly connected to the left side of the sliding plate. A lead screw is threadedly connected to the inner surface of the threaded cylinder. A first bevel gear is fixedly connected to the bottom surface of the lead screw. A second bevel gear meshes with the left side of the first bevel gear. A motor is fixedly connected to the inner wall of the lifting box. The surface of the motor's output shaft is fixedly connected to the middle of the second bevel gear. By rotating the lead screw, the first threaded cylinder moves up and down, causing the sliding plate to move up and down, facilitating the grinding of the ship hull by the grinding disc and avoiding the need for workers to move up and down. This significantly increases the efficiency of grinding ship steel structures.

[0004] However, the above-mentioned technology only uses a lead screw to drive the grinding disc to move up and down to grind the ship's steel structure. The surface of the ship's steel structure is often not completely flat and has various inclined surfaces. This requires the grinding device to be tilted to grind it. However, the existing device is not convenient to adjust the tilt angle of the grinding machine to grind the inclined surfaces, which reduces the grinding efficiency and its practicality is generally limited.

[0026] See Figures 1-5 This utility model provides two technical solutions:

[0027] First embodiment: A ship steel structure grinding device, including a base 1, and further comprising:

[0028] Limiting mechanism 2 is installed on the top surface of base 1 to fix the position of the ship's steel structure;

Base plate 31 is movably installed on the rear side of the top surface of base 1, and mounting groove plate 35 is fixedly installed on the top surface of base plate 31.

[0030] The grinding mechanism 4, located on the front side of the mounting slot plate 35, is used to grind the steel structure of the ship. The grinding mechanism 4 includes a fixed slot plate 41 movably mounted on the front side of the base 1. An L-shaped plate 43 is movably mounted inside the fixed slot plate 41. A telescopic rod 42, which drives the L-shaped plate 43 to move, is fixedly mounted on the rear side of the inner cavity of the fixed slot plate 41. A rotating assembly is provided on the front side of the L-shaped plate 43 for adjusting the grinding angle of the device. The output end of the telescopic rod 42 is fixedly mounted on the rear side of the L-shaped plate 43, and activating the telescopic rod 42 can drive the L-shaped plate 43 to move and adjust. At the front and rear positions of the grinder 49, the front side of the L-shaped plate 43 movably passes through the interior of the fixed groove plate 41 and extends to the front side of the fixed groove plate 41. The rotating assembly includes a connecting frame 45 fixedly installed on the front side of the base 1 on the top surface of the L-shaped plate 43.

Starting the drive motor 34 can drive the first screw 33 to rotate and adjust the position of the mounting slot 35 through the base plate 31.

[0033] The position and height of the grinding mechanism 4 can be easily adjusted by the cylinder 21 and the mounting slot 35 to grind the steel structure of the ship. When in use, starting the drive motor 34 can drive the first screw 33 to rotate. Then the first screw 33 will move laterally through the base plate 31 to adjust the mounting slot 35. Then starting the DC motor 37 can drive the second screw 36 to rotate and adjust the height of the fixed slot 41 to grind the steel structure of the ship. It is convenient, fast and practical.

[0034] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0035] In use, the operator pushes the ship's steel structure into the arc-shaped groove 26. The movable roller 23 reduces friction when pushing the steel structure. Then, the cylinder 21 is activated to clamp and fix the steel structure with the clamping plate 25. Next, the drive motor 34 is activated to rotate the first screw 33. The first screw 33 then moves laterally through the base plate 31 to adjust the mounting groove plate 35. Then, the DC motor 37 is activated to rotate the second screw 36 to move the grinder 49 to the appropriate position. Finally, the telescopic rod 42 is activated to adjust the front of the grinder 49. The grinding machine 49 moves back and forth to grind the ship's steel structure. At this time, the elasticity of several springs 412 can drive the shield 411 to stick to the grinding area of ​​the grinding machine 49 to prevent debris from flying. When it is necessary to adjust the angle of the grinding machine 49, the stepper motor 47 is started to drive the drive gear 46 to rotate. Then, the drive gear 46 can adjust the tilt angle of the grinding machine 49 through the gear block 48. When the appropriate position is adjusted, the stepper motor 47 is stopped to fix the position of the grinding machine 49, and then the grinding of the ship's steel structure can continue.
