[0015] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0016] Reference Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a precast slab moving hoist, including a moving bracket 1; a crossbeam 2 is fixedly connected to the top of the moving bracket 1, and push handles 3 are fixedly connected to both sides of one end of the crossbeam 2; two adjusting grooves 4 are opened on the top of the crossbeam 2, adjusting blocks 5 are slidably connected inside the adjusting grooves 4, connecting blocks 6 are installed at the bottom of the adjusting blocks 5, two chains 7 are installed at the bottom of the connecting blocks 6, and hook lock blocks 8 are fixedly connected to the bottom of the chains 7; a square groove 9 is opened inside the adjusting blocks 5, and pressing blocks 10 are slidably connected to both sides of the square groove 9; a limit block 11 is fixedly connected to one side of the pressing block 10; the two sides of the adjusting groove 4... Each side is provided with several limiting grooves 12. The surface of the limiting block 11 is slidably connected to the inside of the limiting groove 12. Both sides of the adjusting block 5 are provided with sliding grooves 13. Both sides of the adjusting block 5 are fixedly connected with sliders 14. The surface of the sliders 14 is slidably connected to the inside of the sliding grooves 13. A square plate 15 is fixedly connected to the inside of the square groove 9. Both sides of the square plate 15 are fixedly connected with two first springs 16. The other end of the first springs 16 is fixedly connected to the push block 10. Both ends of the push block 10 are provided with guide grooves 17. Both ends of the square groove 9 are fixedly connected with two guide blocks 18. The surface of the guide blocks 18 is slidably connected to the inside of the guide grooves 17. Specifically: By pressing the button 10, the button 10 moves the limiting block 11 out of the limiting groove 12, thereby releasing the limiting position of the adjusting block 5 inside the adjusting groove 4. At this time, the position of the adjusting block 5 can be adjusted according to the length of the precast slab. Adjusting the position of the adjusting block 5 achieves the adjustment of the position of the hook-lock block 8. After the adjusting block 5 is adjusted, the button 10 is released, and the elasticity of the first spring 16 automatically abuts against the button 10, causing the button 10 to move the limiting block 11 back to the limiting groove 12, so that the adjusting block 5 is limited again. By allowing the slider 14 to slide inside the slide groove 13, the adjusting block 5 can move further inside the adjusting groove 4. To enhance stability, the sliding of guide block 18 within guide groove 17 restricts the movement of push block 10, preventing it from wobbling as it moves within square groove 9. This ensures that limit block 11 accurately enters limit groove 12. After adjustment of adjustment block 5, one end of chain 7 is hooked into the prestressing holes at both ends of the precast slab to lift it. This series of settings allows for rapid adjustment of the position of hook block 8 to accommodate precast slabs of different lengths. The entire adjustment process is smooth and convenient, significantly reducing the adjustment time and enabling the lifting equipment to be quickly deployed for subsequent lifting operations. This effectively improves overall work efficiency and reduces downtime caused by adjustment of hook block 8.

[0017] Reference Figure 1 - Figure 5 As shown, in this embodiment: a threaded block 19 is fixedly connected to the surface of the connecting block 6; a threaded groove 20 is provided at the bottom of the adjusting block 5; the threaded block 19 is threadedly connected to the threaded groove 20; a plurality of sliding circular grooves 21 are provided at the bottom of the hook lock block 8; a movable rod 22 is slidably connected inside the sliding circular groove 21; a second spring 23 is slidably connected to the surface of the movable rod 22; the top of the second spring 23 is fixedly connected to the top of the movable rod 22; the bottom of the second spring 23 is fixedly connected to the bottom of the sliding circular groove 21; a load-bearing plate 24 is fixedly connected to the bottom of the movable rod 22; an elastic pad 25 is fixedly connected to the surface of the load-bearing plate 24; and a scale marking line 27 is provided at the top of the crossbar 2, with the scale marking line 27 located on one side of the top of the adjusting groove 4. Specifically: By threading the threaded block 19 to the threaded groove 20, the adjusting block 5 and the connecting block 6 can be quickly separated, facilitating equipment storage, replacement, and transportation. By setting the load-bearing plate 24, the load-bearing plate 24 is supported on the bottom of the precast slab, making the hoisting of the precast slab more stable. The elasticity of the second spring 23, through abutting the movable rod 22, can pull back the load-bearing plate 24, making the connection between the load-bearing plate 24 and the precast slab tighter. By setting the scale marking line 27, the user can clearly understand the movement position of the adjusting block 5, avoiding the user having to repeatedly measure when adjusting the adjusting block 5.

[0018] Working principle: By pressing the button 10, the user causes the limiting block 11 to move out of the limiting groove 12, thereby releasing the limiting position of the adjusting block 5 in the adjusting groove 4. At this time, the position of the adjusting block 5 can be adjusted according to the length of the precast slab, thereby adjusting the position of the hook-lock block 8. After the adjusting block 5 is adjusted, the user releases the button 10. The elasticity of the first spring 16 automatically abuts against the button 10, causing the button 10 to automatically reset the limiting block 11, returning it to the limiting groove 12, and allowing the adjusting block 5 to regain its limiting position. By allowing the slider 14 to slide inside the slide groove 13, the movement of the adjusting block 5 inside the adjusting groove 4 can be made more stable. By allowing the guide block 18 to slide inside the guide groove 17, the movement position of the pressing block 10 can be restricted, preventing the pressing block 10 from shaking when moving inside the square groove 9, and ensuring that the limiting block 11 accurately enters the limiting groove 12. After the adjusting block 5 is adjusted, one end of the locking chain 7 is hooked into the prestressing holes at both ends of the precast slab to realize the hoisting of the precast slab. This series of settings can quickly adjust the position of the hook locking block 8 to adapt to precast slabs of different lengths.

[0019] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
