Description

Technical Field

[0001] This utility model relates to the field of water quality monitoring technology, specifically a special tool for hoisting stacked steel plates. Background Technology

[0002] In the metallurgical industry, steel plate stacking and hoisting is a critical and frequent logistics operation, mainly used to safely and efficiently transfer rolled or cut steel plates (usually multiple sheets stacked together) to designated locations (such as stockyards, warehouses, loading points, or the entrance to the next process). This process relies heavily on heavy-duty overhead cranes (gantry cranes) in conjunction with specialized lifting tools (such as powerful electromagnetic chucks, vacuum chucks, or groups of hooks / beams). The core challenge of this operation is ensuring the stability of the entire stack of steel plates during lifting, moving, and placement, preventing individual steel plates from slipping, falling, or bending and deforming. This places extremely high demands on the uniformity of the suction / clamping force of the lifting tools, the precise control of the operators, and strict safety procedures. It is a key link in ensuring smooth production processes, the safety of personnel and equipment, and the integrity of steel plate quality.

The shape and size of the third limiting telescopic rod 19 also partially match the shape and size of the fifth limiting telescopic hole 20, allowing the third limiting telescopic rod 19 to move within the fifth limiting telescopic hole 20.

[0037] In this implementation plan, the above-mentioned technology ensures the stability of the connection and telescopic adjustment between the second L-shaped frame 2, the third L-shaped frame 3, and the fourth L-shaped frame 4.

[0038] Furthermore:

[0039] In an optional embodiment, the second limiting telescopic hole 14 is further provided with:

[0040] The second connecting bearing 11 is fixedly installed inside the rear end of the second limiting telescopic hole 14.

The second adjusting threaded rod 12 is movably connected to the second L-shaped frame 2 through the second connecting bearing 11. The second adjusting threaded rod 12 is threadedly connected to the second limiting telescopic rod 13.

[0041] In this implementation plan: by rotating the second adjusting threaded rod 12, the second limiting telescopic rod 13 is pushed against the inner wall of the third limiting telescopic hole 15, thereby improving the stress stability of the second L-shaped frame 2 and the third L-shaped frame 3 during hoisting.

[0042] Furthermore:

[0043] In an optional embodiment, the fourth limiting telescopic hole 18 is further provided with:

[0044] The third connecting bearing 16 is fixedly installed inside the right side of the fourth limiting telescopic hole 18. The third adjusting threaded rod 17 passes through the inside of the third connecting bearing 16. The third adjusting threaded rod 17 is movably connected to the third L-shaped frame 3 through the third connecting bearing 16. The third adjusting threaded rod 17 is threadedly connected to the third limiting telescopic rod 19.

[0045] In this implementation plan: by rotating the third adjusting threaded rod 17, the third limiting telescopic rod 19 is pushed against the inner wall of the fifth limiting telescopic hole 20, thereby improving the stress stability of the third L-shaped frame 3 and the fourth L-shaped frame 4 during hoisting.

[0046] Furthermore:

[0047] In an optional embodiment, the fourth adjusting threaded rod 22 is further provided with:

[0048] The first limiting tooth 25 is fixedly installed at the front end of the fourth adjusting threaded rod 22. A limiting structure 26 is installed on the right side of the first limiting tooth 25, and the limiting structure 26 is fixedly connected to the fourth L-shaped frame 4. The limiting structure 26 also includes a fixed box 263. A limiting movable plate 266 is movably installed inside the fixed box 263. A limiting spring 264 is fixedly installed on the right side of the limiting movable plate 266. A push rod 262 is fixedly installed on the left side of the limiting movable plate 266. An arc plate 261 is fixedly installed on the left side of the push rod 262. A second limiting tooth 265 corresponding to the first limiting tooth 25 is fixedly installed on the left side of the arc plate 261. The limiting movable plate 266 is elastically connected to the fixed box 263 through the limiting spring 264. The push rod 262 passes through the inner wall of the fixed box 263.

[0049] In this implementation scheme: the above technical solution restricts the rotation of the first adjusting threaded rod 7, the second adjusting threaded rod 12, the third adjusting threaded rod 17, and the fourth adjusting threaded rod 22, preventing the four adjusting threaded rods from rotating under the action of external force or vibration, thus affecting the size of the frame formed by the first L-shaped frame 1, the second L-shaped frame 2, the third L-shaped frame 3, and the fourth L-shaped frame 4.

[0050] Working principle: When using this special tool for hoisting stacked steel plates, first push the arc plate 261 to separate the second limiting tooth 265 from the first limiting tooth 25. Then, turn the fourth adjusting threaded rod 22 to push the fourth limiting telescopic rod 23 to move inside the sixth limiting telescopic hole 24, thereby adjusting the distance between the first L-shaped frame 1 and the fourth L-shaped frame 4, as well as the second L-shaped frame 2 and the third L-shaped frame 3, to the set distance. Next, release the arc plate 261. The limiting spring 264 inside the fixed box 263 pushes the limiting movable plate 266 to move forward through its own elasticity. Through the push rod 262 and the arc plate 261, the second limiting tooth 265 engages with the first limiting tooth 25, restricting the fourth adjusting threaded rod 22 and preventing it from rotating. Similarly, turn the first adjusting threaded rod 7 to push the first limiting telescopic rod 9 to the first limiting hole 24. The internal movement of the telescopic hole 10 adjusts the spacing between the first L-shaped frame 1, the second L-shaped frame 2, the third L-shaped frame 3, and the fourth L-shaped frame 4 to a suitable distance. Next, the second adjusting threaded rod 12 is turned to push the second limiting telescopic rod 13 to move inside the second limiting telescopic hole 14 and the third limiting telescopic hole 15, so that the second limiting telescopic rod 13 abuts against the inner wall of the third limiting telescopic hole 15. Similarly, the third adjusting threaded rod 17 is turned to push the third limiting telescopic rod 19 to move inside the fourth limiting telescopic hole 18 and the fifth limiting telescopic hole 20, abutting against the inner wall of the fifth limiting telescopic hole 20. Then, the lifting tool is hung on the lifting machinery by the lifting rope and the lifting rings above the four L-shaped frames. Finally, the hook 5 below the wire rope 6 hooks the stack of plates, realizing the lifting of the stack of plates and the steel plates above them. This is the working principle of the special tool for lifting stacked steel plates.
