In industrial production and construction, steel plates that require specific sizes or special shapes are sometimes encountered, and these steel plates usually do not meet traditional standard specifications. These non-standard steel plates may differ in size, thickness, shape, material, etc., and may need to be customized according to specific needs. During the hoisting process, they need to remain stable, so a hoisting device for large non-standard steel plate processing is proposed.

[0025] Next, in combination with the accompanying drawings of the present specification, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Refer to Figure 1 - Figure 2 , an embodiment provided by the present invention: A hoisting device for processing large non-standard steel plates, including a support frame 1, a stable base 2 is fixedly connected to the inner wall of the support frame 1, a hydraulic cylinder 3 is fixedly connected to the upper surface of the stable base 2, the output end of the hydraulic cylinder 3 is fixedly connected to a moving plate 4, the lower surface of the moving plate 4 is slidably connected to a guide rail 5, the lower surface of the guide rail 5 is fixedly connected to the inner wall of the support frame 1, the upper surface of the moving plate 4 is rotatably connected to a connecting rod 6, the lower surface of the connecting rod 6 is rotatably connected to a rotating plate 7, the inside of the rotating plate 7 is rotatably connected to a fixed column 8, the bottom end of the fixed column 8 is fixedly connected to the inner wall of the support frame 1, a positioning block 9 is fixedly connected to the upper surface of the moving plate 4, and an placing assembly is arranged on the inner wall of the support frame 1; The placing assembly includes a placing table 10, the outer wall of the placing table 10 is fixedly connected to the inner wall of the support frame 1, a chute 11 is opened inside the placing table 10, and the outer wall of the positioning block 9 is slidably connected to the inner wall of the chute 11;

[0027] Specifically, the support frame 1 has a fixing effect on the stable base 2, and the stable base 2 can ensure the stability of the operation of the hydraulic cylinder 3. When the hydraulic cylinder 3 is opened, its output end can drive the moving plate 4 to slide left and right on the upper surface of the guide rail 5. Furthermore, the moving plate 4 can drive the rotating plate 7 to rotate on the outer wall of the fixed column 8 through the connecting rod 6. At this time, the rotating plate 7 can drive the other moving plate 4 at the other end to move relatively synchronously through the connecting rod 6 at the other end, so as to drive the positioning block 9 to slide on the inner wall of the chute 11. When the positioning blocks 9 at both ends are in contact with the outer wall of the steel plate, the steel plate can be centered and positioned, which can ensure the stability of the position of the steel plate and prevent it from falling off, causing safety accidents.

[0028] Refer to Figure 1 - Figure 3, a sliding column 12 is slidably connected inside the positioning block 9. A pressing plate 13 is fixedly connected to the bottom end of the sliding column 12. The outer wall of the pressing plate 13 is slidably connected to the inner wall of the positioning block 9. A first spring 14 is fixedly connected to the upper surface of the pressing plate 13, and the top end of the first spring 14 is fixedly connected to the inner wall of the positioning block 9; a pressing block 15 is fixedly connected to the top end of the sliding column 12, and a linkage plate 16 is fixedly connected to the inner wall of the pressing block 15;

[0029] Specifically, the positioning block 9 can support the sliding position of the sliding column 12. At the same time, when the sliding column 12 moves downward, it can drive the pressing plate 13 to slide on the inner wall of the positioning block 9. At the same time, when the first spring 14 rebounds, it can pull the pressing plate 13 downward, thereby driving the pressing block 15 fixed by the sliding column 12 to fit the upper surface of the steel plate. At the same time, the technician can pull the linkage plate 16 to adjust its height to better fit and press different thicknesses of steel plates.

[0030] Refer to Figure 1 and Figure 4 , a limiting frame 17 is fixedly connected to the upper surface of the support frame 1, and a steering wheel 25 is fixedly connected to the lower surface of the support frame 1; a fixing plate 18 is fixedly connected to the inner wall of the limiting frame 17, a sleeve 19 is fixedly connected to the upper surface of the fixing plate 18, and a first toothed disk 20 is fixedly connected to the inner wall of the sleeve 19; a guiding column 21 is slidably connected inside the first toothed disk 20. A pull ring 22 is fixedly connected to the top end of the guiding column 21, a second toothed disk 23 is fixedly connected to the bottom end of the guiding column 21, and the outer wall of the second toothed disk 23 is slidably connected to the inner wall of the sleeve 19; the upper surface of the second toothed disk 23 is arranged on the lower surface of the first toothed disk 20, and a second spring 24 is arranged on the lower surface of the second toothed disk 23. The bottom end of the second spring 24 is fixedly connected to the upper surface of the fixing plate 18;

[0031] Specifically, the support frame 1 has a fixed support function for the limiting frame 17. At the same time, the limiting frame 17 can ensure the stability of the four corners of the support frame 1 and prevent tipping over. The steering wheel 25 can drive the support frame 1 to rotate. The limiting frame 17 has a fixed support function for the fixing plate 18, and the fixing plate 18 can support the position of the sleeve 19. The sleeve 19 can fix the position of the first toothed disk 20. The first toothed disk 20 can support the sliding position of the guiding column 21. At the same time, the guiding column 21 has a fixed support function for the pull ring 22, and the pull ring 22 is the connection point for the cable, thereby carrying out the hoisting work. At the same time, the guiding column 21 can drive the second toothed disk 23 to slide downward on the inner wall of the sleeve 19. When the second toothed disk 23 slides downward and disengages from the lower surface of the first toothed disk 20, the rotation angle of the support frame 1 can be adjusted. After adjusting to the appropriate angle, the second spring 24 rebounds to drive the second toothed disk 23 to fit with the first toothed disk 20, fixing its rotation angle and ensuring the accuracy of the steel plate position.

[0032] Working principle: When this device is needed, technicians can place the steel plate on the upper surface of the placement table 10. Then, turn on the hydraulic cylinder 3 supported by the stabilizing base 2. The output end of the hydraulic cylinder 3 can drive the moving plate 4 to slide left and right on the upper surface of the guide rail 5. Furthermore, the moving plate 4 can drive the rotating plate 7 to rotate on the outer wall of the fixed column 8 through the connecting rod 6. At this time, the rotating plate 7 can drive the other moving plate 4 at the other end to move relatively synchronously through the connecting rod 6 at the other end, thereby driving the positioning block 9 to slide on the inner wall of the sliding groove 11. When the positioning blocks 9 at both ends are in contact with the outer wall of the steel plate, the steel plate can be positioned. At the same time, when the positioning block 9 approaches the steel plate, the pressing block 15 will slide onto the upper surface of the steel plate, and the upper surface of the steel plate can be pressed tightly through the first spring 14 to achieve a better fixing effect on the steel plate and improve safety. At the same time, when the thickness of the steel plate is too high, technicians can pull the linkage plate 16 upward. The linkage plate 16 can drive the sliding column 12 to slide upward inside the positioning block 9 through the pressing blocks 15 at both ends, and the sliding column 12 can compress the first spring 14 through the pressure plate 13. After the positioning block 9 positions the steel plate, release the linkage plate 16, and the first spring 14 rebounds to drive the pressing block 15 to fit with the steel plate for fixation. When the hoisting angle needs to be adjusted, after placing the device in place, technicians can drive the guide post 21 to slide downward inside the first toothed disk 20, thereby driving the second toothed disk 23 to slide downward inside the sleeve 19 fixed by the fixed plate 18 until its upper surface is separated from the lower surface of the first toothed disk 20. Then, hold the limiting frame 17 tightly and drive the device to rotate through the steering wheel 25. After adjusting to the appropriate angle, release the guide post 21. The cable can pull the guide post 21 upward through the pull ring 22, and at the same time, the second spring 24 rebounds to drive the second toothed disk 23 to fit with the first toothed disk 20, thereby fixing the rotation angle of the device. The steel plate can be accurately positioned to the required position and angle, improving the flexibility of the device. That is, this device can not only ensure the stable positioning of steel plates of different sizes during processing, avoid processing errors or accidents caused by accidental movement or swing, and improve safety, but also ensure that the workpiece is always in an appropriate position and angle during processing, improving the precision and flexibility of steel plate processing.

Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
