Technical Field
[0001] This utility model belongs to the field of color steel plate technology, and specifically relates to a hoisting device for installing color steel plates. Background Technology
[0002] Color-coated steel sheet, also known as pre-painted steel sheet, is a type of steel sheet with an organic coating. It uses cold-rolled high-strength zinc sheet as a base, undergoes a series of treatments, and is then coated with organic materials and baked. Color-coated steel sheets are highly corrosion-resistant, lightweight yet strong, easy to form, aesthetically pleasing, durable, and colorfast. They are available in single-layer, composite, and floor-deck versions. They are widely used for walls and roofs of large public buildings, public factories, prefabricated houses, and integrated housing. During installation, hoisting equipment is often required to move the color-coated steel sheets.
[0003] Existing hoisting devices have a fixed structure and cannot be adjusted as needed, resulting in poor applicability and taking up a lot of storage space. Furthermore, existing hoisting devices do not provide sufficient clamping stability for color steel plates during transportation, which can easily cause the color steel plates to fall during transport. Therefore, we propose a hoisting device for installing color steel plates. Utility Model Content
[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a hoisting device for installing color steel plates, so as to solve the problems mentioned in the background art. The existing hoisting devices have a fixed structure, cannot be adjusted as needed, have poor applicability, and take up a lot of space when stored. In addition, the existing hoisting devices do not have sufficient clamping stability for color steel plates during transportation, which can easily lead to the color steel plates falling during transportation.

A pull rod is fixedly connected to the surface of the pawl. A fixing rod is fixedly connected to the other side of the adjusting rod. A connecting rod is rotatably connected to the surface of the fixing rod. A lifting ring is fixedly connected to the bottom of the connecting rod. A clamping plate is fixedly connected to the bottom of the lifting ring. A clamping structure is provided inside the clamping plate. The clamping structure includes a threaded rod. A knob is fixedly connected to the top of the threaded rod. A pressure plate is rotatably connected to the bottom of the threaded rod.
[0006] Preferably, one side of the adjusting rod and the rotating rod are rotatably connected in the adjusting groove, the ratchet is rotatably connected inside the circular groove, and the rotating rod passes through both ends of the adjusting groove and is fixedly connected to the ratchet.

[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This hoisting device for installing color steel plates features an adjustment structure. When the adjusting rod and rotating rod one are rotated and lifted in the adjusting groove, the ratchet rotates. A coil spring keeps the pawl engaged with the ratchet surface, preventing the ratchet from rotating in the opposite direction and thus preventing the adjusting rod from rotating downwards. This allows the adjusted angle of the adjusting rod to be fixed. When the adjusting rod needs to be rotated downwards and retracted, pulling the lever causes the pawl and rotating rod two to rotate a certain angle in the rotating groove. The pawl and ratchet are no longer engaged, allowing the ratchet to rotate freely. The adjusting rod can then be rotated downwards and retracted. When rotating rod two rotates, the coil spring on its surface deforms, causing it to tend to return to its original position. Releasing the lever pulls the rotating rod two, which, under the action of the coil spring, causes the pawl to rotate and engage with the ratchet. This allows the angle of the adjusting rod to be adjusted to accommodate different sizes of color steel plates. Furthermore, when not in use, the adjusting rod can be retracted downwards, reducing the space occupied by the hoisting device and facilitating storage.
[0014] 2. This type of hoisting device for installing color steel plates is equipped with clamping plates and a pressing structure. The color steel plate is placed in the clamping plates on both sides, and the knob is turned to drive the threaded rod to rotate, so that the pressure plate descends and presses on the top of the color steel plate, thereby increasing the stability of the color steel plate during transportation and reducing the possibility of it falling during transportation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-6 One embodiment provided by this utility model:
[0024] A hoisting device for installing color steel panels includes a top frame 1. Adjustment grooves 11 are provided on both sides of the top frame 1. Circular grooves 12 are provided at both ends of the adjustment grooves 11. A rotating groove 13 is provided on one side of the circular groove 12. Installation grooves 14 are provided at both ends of the rotating groove 13. Circular grooves 15 are provided at both ends of the rotating groove 13. Adjustment structures 2 are provided on both sides of the top frame 1. The adjustment structure 2 includes an adjustment rod 21. A rotating rod 22 is fixedly connected to one side of the adjustment rod 21. Ratchets 23 are fixedly connected to both ends of the rotating rod 22. Pads 24 are abutted against the surface of the ratchet 23. A rotating rod 25 is fixedly connected inside the pawl 24. The rotating rod 25... A coil spring 26 is fixedly connected to one end of the rotating rod 25. Limit blocks 27 are fixedly connected to both ends of the rotating rod 25. A pull rod 28 is fixedly connected to the surface of the pawl 24. A fixing rod 29 is fixedly connected to the other side of the adjusting rod 21. A connecting rod 3 is rotatably connected to the surface of the fixing rod 29. A lifting ring 31 is fixedly connected to the bottom of the connecting rod 3. A clamping plate 32 is fixedly connected to the bottom of the lifting ring 31. A clamping structure 4 is provided inside the clamping plate 32. The clamping structure 4 includes a threaded rod 41. A knob 42 is fixedly connected to the top of the threaded rod 41. A pressure plate 43 is rotatably connected to the bottom of the threaded rod 41. An adjusting structure 2 is provided to place the adjusting rod 21 and the rotating rod 22 in the adjusting groove 11. When the ratchet rotates and then lifts, it drives the ratchet 23 to rotate. The coil spring 26 keeps the pawl 24 constantly engaged with the surface of the ratchet 23. The ratchet 23 and pawl 24 work together to prevent the ratchet 23 from rotating in the opposite direction, thus preventing the adjusting rod 21 from rotating downwards. This allows the adjusted angle of the adjusting rod 21 to be fixed. When it is necessary to rotate the adjusting rod 21 downwards to retract it, pulling the lever 28 causes the pawl 24 and the second rotating rod 25 to rotate a certain angle within the rotating groove 13. The pawl 24 and ratchet 23 are no longer engaged, allowing the ratchet 23 to rotate freely. This allows the adjusting rod 21 to rotate downwards to retract. When the second rotating rod 25 rotates, the coil spring 26 on its surface deforms, causing the rotating rod 25 to rotate downwards. The second movable lever 25 has a tendency to return to its original position. After the pull rod 28 is released, the second movable lever 25 is pulled to rotate under the action of the coil spring 26, so that the pawl 24 rotates and abuts against the ratchet 23. The angle of the adjusting rod 21 can be adjusted to accommodate different sizes of color steel plates. At the same time, when not in use, the adjusting rod 21 can be retracted downwards to reduce the space occupied by the hoisting device and facilitate storage. A clamping plate 32 and a pressing structure 4 are set up. The color steel plate is placed in the clamping plates 32 on both sides. Turning the knob 42 drives the threaded rod 41 to rotate, so that the pressure plate 43 descends and presses on the top of the color steel plate, thereby increasing the stability of the color steel plate during transportation and reducing the possibility of falling during transportation.
[0025] Furthermore, one side of the adjusting rod 21 and the rotating rod 22 are rotatably connected in the adjusting groove 11, and the ratchet 23 is rotatably connected in the circular groove 12. The rotating rod 22 passes through both ends of the adjusting groove 11 and is fixedly connected to the ratchet 23. When the adjusting rod 21 and the rotating rod 22 are rotated in the adjusting groove 11 and the adjusting rod 21 is lifted, the ratchet 23 is driven to rotate in the circular groove 12. The coil spring 26 keeps the pawl 24 abutting against the surface of the ratchet 23. With the cooperation of the ratchet 23 and the pawl 24, the ratchet 23 cannot rotate in the opposite direction, and the adjusting rod 21 cannot rotate downward.
[0026] Furthermore, both the pawl 24 and the second rotating rod 25 are rotatably connected inside the rotating groove 13. The rotating groove 13 is connected to the first circular groove 12. The pawl 24 and the ratchet 23 are engaged with each other. The pull rod 28 passes through the side surface of the top frame 1 and is fixedly connected to the pawl 24. Pulling the pull rod 28 causes the pawl 24 and the second rotating rod 25 to rotate a certain angle in the rotating groove 13. The pawl 24 and the ratchet 23 are no longer engaged, allowing the ratchet 23 to rotate freely, thereby rotating the adjusting rod 21 downwards and retracting it.
[0027] Furthermore, one end of the coil spring 26 is fixedly connected to the surface of the rotating rod 25, and the other end of the coil spring 26 is fixedly connected to the inner wall of the mounting groove 14. When the rotating rod 25 rotates, the coil spring 26 on its surface deforms, giving the rotating rod 25 a tendency to return to its original state.
[0028] Furthermore, the limiting block 27 is rotatably connected inside the circular groove 15. The radius of the limiting block 27 is larger than the radius of the rotating rod 25. The radius of the limiting block 27 is the same as the radius of the circular groove 15. Through the cooperation of the limiting block 27 and the circular groove 15, the rotating rod 25 is limited to prevent it from sliding.
[0029] Furthermore, both sides of the adjusting rod 21 are provided with rounded corners. A square groove is provided on the side of the adjusting rod 21 away from the top frame 1. The fixing rod 29 is fixedly connected in the square groove. The top of the connecting rod 3 is rotatably connected to the surface of the fixing rod 29. The top of the connecting rod 3 is provided with rounded corners. The rounded corners facilitate the rotation of one side of the adjusting rod 21 in the adjusting groove 11 and the rotation of the top of the connecting rod 3 in the square groove.
[0030] Furthermore, the clamping plate 32 is C-shaped, and the pressure plate 43 is slidably connected to the inner side of the clamping plate 32. The bottom of the pressure plate 43 is provided with a rubber pad layer to increase the friction between it and the color steel plate and avoid damage to the surface of the color steel plate. The color steel plate is placed in the clamping plates 32 on both sides, and the knob 42 is turned to drive the threaded rod 41 to rotate, so that the pressure plate 43 descends and presses on the top of the color steel plate, thereby increasing the stability of the color steel plate during transportation.
[0031] Working principle: When the adjusting rod 21 and rotating rod 22 are rotated and lifted in the adjusting groove 11, the ratchet 23 is driven to rotate. The coil spring 26 keeps the pawl 24 abutting against the surface of the ratchet 23. The ratchet 23 cannot rotate in the opposite direction, preventing the adjusting rod 21 from rotating downwards. This allows the adjusted angle of the adjusting rod 21 to be fixed. The color steel plate is placed in the clamps 32 on both sides. Rotating the knob 42 drives the threaded rod 41 to rotate, causing the pressure plate 43 to descend and press against the top of the color steel plate, thus increasing the stability of the color steel plate during transportation. To retract the adjusting rod 21 by rotating it downwards, pull... Pull rod 28 drives pawl 24 and rotating rod 25 to rotate a certain angle within rotating groove 13. Pawl 24 and ratchet 23 are no longer engaged, allowing ratchet 23 to rotate freely. This causes adjusting rod 21 to rotate downwards and retract. When rotating rod 25 rotates, the coil spring 26 on its surface deforms, giving rotating rod 25 a tendency to return to its original position. After releasing pull rod 28, rotating rod 25 is pulled to rotate under the action of coil spring 26, causing pawl 24 to rotate and engage with ratchet 23. This allows adjustment of the angle of adjusting rod 21 to accommodate different sizes of color steel plates. At the same time, when not in use, adjusting rod 21 can be retracted downwards to reduce the space occupied by the hoisting device.
