Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically a hoisting device for temporary reinforcement and relocation of steel structures. Background Technology

[0002] In the field of construction engineering, the following practical difficulties are often encountered when carrying out temporary reinforcement of tall spatial structures: Construction challenges in confined spaces: In indoor venues, narrow alleys, and other areas, large lifting equipment (such as crawler cranes, truck cranes, and boom cranes) cannot enter due to lack of access channels or site restrictions; Strong reliance on traditional processes: In temporary reinforcement of clearly relocated projects, existing indoor reinforcement technologies generally adopt a construction mode of "scaffolding erection + manual handling + construction platform," which requires a large amount of steel pipes and other materials to build the operating platform, and high-altitude operations rely on manual labor to position components; Low level of mechanization: For steel components weighing over 200 kg, the efficiency of manual handling is less than 0.2 tons / hour, and frequent interruptions are required for temporary reinforcement, leading to chaotic process connections.

[0003] Existing technologies require a significant amount of time for scaffolding erection, resulting in a lengthy construction period. During subsequent construction and handling, manual handling at heights can easily lead to falls and component slippage accidents. Furthermore, temporary supports are limited by the site conditions, have poor stability, and pose a risk of instability.

[0004] Therefore, a hoisting device for temporary reinforcement and relocation of steel structures is proposed to address the above problems. Utility Model Content

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.

[0025] Example 1

[0026] Please see Figure 1-6As shown, a hoisting device for temporary reinforcement and relocation of steel structures includes a base 1. Rotating columns 11 are symmetrically fixedly connected to both sides of the interior of the base 1. Rotating plates 2 are rotatably connected to the tops of multiple rotating columns 11. A first support frame 5 and a second support frame 6 are detachably connected to the top of the base 1. A transmission assembly is installed inside the base 1. Ball screws 3 are slidably connected to the inner sides of both sets of rotating plates 2 via sliding frames. A support plate 4 is fixedly connected to the bottom of the ball screws 3. A top plate 7 is detachably connected to the tops of the first support frame 5 and the second support frame 6. A winch 8 is mounted on the top of the top plate 7 via a turntable. The transmission assembly includes worm gears 9 and a linkage unit. The worm gears 9 are rotatably connected to both sides of the interior of the base 1. Worm wheels 10 are fixedly connected to one side of the top of each set of rotating plates 2. Multiple worm gears 9 are coupled to corresponding worm wheels 10. The support plate 4 is raised and lowered via the linkage unit, which includes a first bevel gear 12 and multiple rotating columns 11. The top of the base 1 extends into the interior of the rotating plate 2, where a first bevel gear 12 is fixedly connected. Multiple rotating plates 2 are rotatably connected to a rotating shaft 13. One end of the rotating shaft 13 is fixedly connected to a second bevel gear 14, with the first bevel gear 12 meshing with the second bevel gear 14. The other end of the rotating shaft 13 is fixedly connected to a third bevel gear 15. A threaded ring 17 is rotatably connected to one side of the rotating plate 2, outside the ball screw 3. The ball screw 3 is connected to the threaded ring 17 via a screw nut pair. A fourth bevel gear 16 is fixedly connected to the outside of the threaded ring 17, with the third bevel gear 15 meshing with the fourth bevel gear 16. The linkage unit also includes a synchronous pulley 18. One end of each of the two worm gears 9 extends into the exterior of the base 1, where a synchronous pulley 18 is fixedly connected. The two synchronous pulleys 18 are connected via a synchronous belt 19. A motor 20 is fixedly connected to one side of the base 1 via a mounting plate, and the output end of the motor 20 is fixedly connected to one of the worm gears 9.

[0027] When using this device, first push the base 1 to the designated working position using the casters 23, and then move the first support frame 5 and the second support frame 6 to the working position. Then start the motor 20, which drives the corresponding worm gear 9 to rotate. Through the transmission relationship between the two first synchronous pulleys 18 and the synchronous belt 19, the two worm gears 9 rotate synchronously. The worm gears 9 then drive the corresponding worm wheel 10 and the rotating plate 2 to rotate. During rotation, the rotating plate 2 drives the second bevel gear 14 to rotate around the first bevel gear 12. This meshing relationship drives the second bevel gear 14 and the rotating shaft 13 to rotate. The rotating shaft 13 then drives the third bevel gear 15 to rotate, causing the third bevel gear 15 to mesh with the fourth bevel gear 16 and the threaded ring 17, thus rotating the threaded ring 17. The ball screw 3 and support plate 4 are driven by the lead screw and nut pair to move downward under the limit of the limit frame until the rotating plate 2 rotates open by 90°. The support plate 4 can then descend to the point where it is in contact with the ground, thereby providing support for the device and improving its stability during use, preventing shaking and tilting during operation. The opened first support frame 5 and second support frame 6 are then fitted onto multiple positioning pins 21 through the insertion holes, and then multiple first bolts 22 are tightened. The same process is followed when installing the top plate 7, thus completing the installation of the first support frame 5 and second support frame 6, the top plate 7 and the winch 8. The installation is relatively convenient, eliminating the trouble of welding. Only one worker is needed for quick installation and disassembly, effectively improving installation efficiency and greatly reducing the workload of the workers.

[0028] The base 1 has symmetrically fixed pins 21 on both sides of the top and bottom of the top plate 7. Threaded holes are provided on the outer sides of the multiple positioning pins 21. Insertion holes that mate with the positioning pins 21 are provided on both sides of the bottom and top of the first support frame 5 and the second support frame 6. First bolts 22 are symmetrically threaded on both sides of the outer sides of the first support frame 5 and the second support frame 6. Multiple first bolts 22 extend into the interior of the positioning pins 21 and are threaded into the corresponding threaded holes. Universal wheels 23 are symmetrically installed on both sides of the bottom of the base 1. The diameter of the second bevel gear 14 is smaller than the diameter of the first bevel gear 12.

[0029] With the above technical solution, the universal wheels 23 set at the bottom of the base 1 can be easily moved, avoiding the trouble of manual handling.

[0030] Example 2

[0031] Please see Figure 6As shown in the first embodiment, as another implementation of this utility model, the inner side of the first support frame 5 is symmetrically rotatably connected with a rotating rod 24, and the inner side of the second support frame 6 is symmetrically fixedly connected with a limiting plate 25 that cooperates with the rotating rod 24. The ends of the two rotating rods 24 away from the first support frame 5 are respectively rotatably connected to the corresponding limiting plate 25. The top of the two limiting plates 25 are threaded with a second bolt 26, and one end of the second bolt 26 extends into the interior of the rotating rod 24 and is threadedly connected to it.

[0032] When using the first support frame 5 and the second support frame 6, the second support frame 6 is opened so that the rotating rod 24 is at a 90° angle to the first support frame 5 and the second support frame 6. Then, the second bolt 26 is tightened into the corresponding rotating rod 24 to fix it. The first support frame 5 and the second support frame 6 can be folded before installation or after disassembly. After folding, the volume is greatly reduced, which greatly reduces the space occupied during transportation and storage and improves the convenience of transportation.
