Description

Technical Field

[0001] This utility model relates to the field of building wall panel hoisting technology, and in particular to a prefabricated building wall panel hoisting device. Background Technology

[0002] In prefabricated building construction, wall panel hoisting is a crucial step. Currently, commonly used hoisting equipment mostly uses fixed-size clamps, which are difficult to adapt to wall panels of different widths and thicknesses. Changing clamps is not only time-consuming but also reduces construction efficiency. Furthermore, traditional devices lack clamping stability, and wall panels are prone to slippage due to vibration during hoisting, posing safety hazards. At the same time, most devices lack elastic buffer structures, which can easily cause bumps and damage to the edges and corners of wall panels during clamping, increasing material waste. In addition, the anti-slip components of some devices are inconvenient to replace after wear, resulting in high maintenance costs. These devices fail to meet the requirements of efficient and safe construction and have certain adverse effects on the user experience. To address the shortcomings of existing technologies, we propose a prefabricated building wall panel hoisting device. Utility Model Content

[0003] The main purpose of this utility model is to provide a prefabricated building wall panel hoisting device, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A prefabricated building wall panel hoisting device includes a base plate. A rotating disk is provided in front of the base plate, and a rotating rod is fixedly connected to the rear end of the rotating disk. A first bevel gear is fixedly connected to the outer surface of the rotating rod. A bearing is detachably embedded in the inner cavity of the base plate. Second bevel gears are meshed on both sides of the first bevel gear, and a threaded rod is fixedly connected to one side of the second bevel gear. Two sets of guide rods are symmetrically fixed inside the base plate. A movable plate is provided on the outer surface of the threaded rod and the two guide rods. A limit plate is fixedly connected to one side of the movable plate. An L-shaped connecting plate is fixedly connected to the other end of the movable plate. Two fixing rods are symmetrically fixed inside the L-shaped connecting plate. Two springs are symmetrically sleeved on the outer surface of the fixing rods. Two sliding plates are slidably connected to the outer surfaces of the two fixing rods. Two connecting rods are symmetrically fixed to one side of the sliding plates. A fixing plate is fixedly connected to the other end of the two connecting rods. Anti-slip plates are detachably connected to the surface of the base plate, the inner side of the L-shaped connecting plate, and the inner side of the fixing plate. Two lifting rings are symmetrically fixed to the upper ends of the two L-shaped connecting plates. A handle is fixedly connected to one side of the fixing plate. Two fastening bolts for fixing the movable plate are symmetrically provided at both the front and rear ends of the base plate.

[0006] Preferably, the end of the rotating rod away from the rotating disk extends into the inner cavity of the base plate and is fixedly connected to the inner ring of the bearing, and the rotating rod forms a rotating structure with the base plate through the bearing.

[0007] Preferably, the two movable plates are threadedly connected to the outer surfaces of the two threaded rods, the two guide rods pass through the movable plates and slide in cooperation with the movable plates, and the cross-section of the guide rods is circular.

[0008] Preferably, the number of springs is four, with two springs forming a group and respectively sleeved on the outer surface of the two fixed rods. The two groups of springs are located on both sides of the sliding plate, with one end of the spring fixedly connected to the inner wall of the L-shaped connecting plate and the other end fixedly connected to the sliding plate.

[0009] Preferably, the anti-slip plate is made of rubber material, and the surface of the anti-slip plate is provided with raised anti-slip particles. The anti-slip plate is detachably connected to the surface of the base plate, the inner side of the L-shaped connecting plate, and the inner side of the fixing plate by countersunk bolts. The head of the countersunk bolt is embedded inside the anti-slip plate and does not protrude from the surface of the anti-slip plate.

[0010] Preferably, the connection between the lifting ring and the L-shaped connecting plate is fixed by welding, the thickness of the weld is not less than the thickness of the lifting ring itself, the fastening bolt passes through the base plate and is threadedly connected to the moving plate, and the end of the fastening bolt is tightly fitted to the surface of the base plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This prefabricated building wall panel hoisting device utilizes a dual adjustment structure combining bevel gear transmission and threaded rod guidance to achieve precise adaptation of the wall panel clamping width. Rotating the rotating disc engages the first bevel gear with the second bevel gears on both sides, driving the threaded rod to rotate. Under the limit of the guide rod, the moving plate moves stably, allowing for rapid adjustment of the L-shaped connecting plate spacing to accommodate wall panels of different widths without the need to change clamps, significantly improving the equipment's versatility. Simultaneously, the fastening bolts lock the moving plate position, preventing spacing deviation due to vibration during hoisting. The raised particle design of the rubber anti-slip plate increases the friction between the wall panel and the device, effectively preventing wall panel slippage and significantly improving structural stability and operational safety during hoisting.

[0013] This prefabricated building wall panel hoisting device features a spring-driven elastic clamping mechanism. Pulling the handle on the fixed plate compresses the spring, allowing for rapid placement of the wall panel. Releasing the handle releases the spring's elastic force, which automatically clamps the wall panel between the sliding plate and the fixed plate, eliminating the need for manual bolt tightening. This simplifies the operation, reduces labor intensity, and improves wall panel clamping efficiency. The anti-slip plate is detachably connected via countersunk bolts, facilitating easy replacement after wear and reducing equipment maintenance costs. The thickness at the weld between the lifting ring and the L-shaped connecting plate is no less than the thickness of the lifting ring itself, enhancing the strength of the load-bearing structure. This device can adapt to the hoisting needs of prefabricated wall panels of varying weights, further expanding its application scenarios and providing an efficient and reliable hoisting solution for building construction.

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Example 1, as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a prefabricated building wall panel hoisting device includes a base plate 1, a rotating disk 2 at the front of the base plate 1, a rotating rod 3 fixedly connected to the rear end of the rotating disk 2, and a first bevel gear 4 fixedly connected to the outer surface of the rotating rod 3. A bearing 5 is detachably embedded in the inner cavity of the base plate 1. The end of the rotating rod 3 away from the rotating disk 2 passes through the inner cavity of the base plate 1 and is fixedly connected to the inner ring of the bearing 5. The rotating rod 3 forms a rotating structure with the base plate 1 through the bearing 5. The bearing 5 is selected to have good radial load-bearing capacity, which can effectively reduce the friction coefficient during the rotation of the rotating rod 3, ensure that the rotating rod 3 drives the first bevel gear 4 to rotate stably, avoid wear of components due to excessive friction, and extend the overall service life of the device. Second bevel gears 6 mesh on both sides of the first bevel gear 4, and a threaded rod 7 is fixedly connected to one side of the second bevel gear 6. Two sets of guide rods 8 are symmetrically fixed inside the base plate 1. Moving plates 9 are provided on the outer surfaces of the threaded rod 7 and the two guide rods 8. Two guide rods 8 are threaded to the outer surfaces of two threaded rods 7 respectively. Two guide rods 8 pass through the movable plate 9 and slide with the movable plate 9. The cross-section of the guide rods 8 is circular. A limit plate 10 is fixedly connected to one side of the movable plate 9. An L-shaped connecting plate 11 is fixedly connected to the other end of the movable plate 9. Two fixing rods 12 are symmetrically fixed inside the L-shaped connecting plate 11. Two springs 13 are symmetrically sleeved on the outer surface of the fixing rods 12. Two sliding plates 14 are slidably connected to the outer surface of the two fixing rods 12. Two connecting rods 15 are symmetrically fixed to one side of the sliding plate 14. A fixing plate 16 is fixedly connected to the other end of the two connecting rods 15. Anti-slip plates 17 are detachably connected to the surface of the base plate 1, the inner side of the L-shaped connecting plate 11, and the inner side of the fixing plate 16. Two lifting rings 18 are symmetrically fixed to the upper ends of the two L-shaped connecting plates 11. A handle 19 is fixedly connected to one side of the fixing plate 16. Two fastening bolts 20 for fixing the movable plate 9 are symmetrically provided at both the front and rear ends of the base plate 1.

[0021] It should be noted that this utility model is a prefabricated building wall panel hoisting device. In use, firstly, rotating the rotating disc 2 drives the rotating rod 3 to rotate within the bearing 5. The rotating rod 3 drives the first bevel gear 4 to rotate, and the first bevel gear 4 meshes with the second bevel gears 6 on both sides, thereby driving the threaded rod 7 to rotate. Since the moving plate 9 is threadedly connected to the threaded rod 7 and guided by the guide rod 8, the rotation of the threaded rod 7 drives the two moving plates 9 to move in opposite directions along the guide rod 8 until the distance between the two L-shaped connecting plates 11 matches the width of the wall panel to be hoisted. At this point, stop rotating the rotating disc 2, tighten the fastening bolts 20 at both ends of the base plate 1 to fix the moving plates 9. Then, pull the fixing plate 16 outwards using the handle 19. The fixing plate 16 drives the sliding plate 14 outwards along the fixing rod 12 via the connecting rod 15. The sliding plate 14 compresses the springs 13 on both sides. Then, place the wall panel to be hoisted on the anti-slip plate 17 on the surface of the base plate 1 to ensure... One side of the wall panel is attached to the anti-slip plate 17 on the inner side of the L-shaped connecting plate 11. Then, the handle 19 is released, and the spring 13 pushes the sliding plate 14 to move inward under its own elastic force. The sliding plate 14 drives the fixed plate 16 to move inward through the connecting rod 15 until the anti-slip plate 17 on the inner side of the fixed plate 16 is tightly attached to the other side of the wall panel, thus clamping and fixing the wall panel. The hook of the hoisting equipment is securely connected to the lifting ring 18 at the upper end of the L-shaped connecting plate 11 with the hoisting rope. Then, the hoisting equipment is started, and the device and wall panel are slowly lifted. During the hoisting process, the operator needs to closely observe the stability of the wall panel. If the wall panel is found to be swaying, the hoisting equipment should be adjusted in time to avoid the wall panel from colliding or slipping. After the wall panel is hoisted to the designated installation position, the device is slowly lowered. After the wall panel is placed stably, the fixed plate 16 is pulled again through the handle 19 to release the clamp on the wall panel. Finally, the hook of the hoisting equipment is separated from the lifting ring 18 to complete one wall panel hoisting operation.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
