Description

Technical Field

[0001] This utility model relates to the field of PC component hoisting technology, and in particular to a PC component hoisting bracket. Background Technology

[0002] PC components are precast concrete parts that can be prefabricated and then assembled, significantly reducing construction time. Lifting scaffolds are often used during the hoisting and transportation of PC components; however, existing hoisting scaffolds have fixed lifting rope positions, making them unadjustable according to the size and type of the component being hoisted. Furthermore, existing hoisting scaffolds often have vertical lifting ropes or supports during hoisting, resulting in significant swaying and poor stability. Therefore, there is an urgent need for a PC component hoisting scaffold that allows for adjustable lifting rope positions based on the component and offers enhanced stability. Utility Model Content

[0005] Preferably, the support plate body includes two parallel horizontal plates, which pass through the support base and are detachably connected to the support base, and also pass through the moving block and are slidably connected to the moving block. The adjustment component is located between the two horizontal plates.

[0006] Preferably, the adjustment assembly includes a rotating cylinder located between the two horizontal plates and rotatably connected to the horizontal plates. A threaded rod is fixedly connected to the side of the moving block near the rotating side. The threaded rod is located between the two horizontal plates and spaced apart from the horizontal plates.

[0014] 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.

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] Reference Figure 1-2This utility model provides a PC component hoisting bracket, including a support plate body 1, with support seats 2 detachably connected to both sides of the support plate body 1, and a support frame 3 fixedly connected to the bottom surface of the support seats 2. Rollers 4 are installed at the bottom end of the support frame 3. Two moving blocks 5 are slidably connected to the support plate body 1. An adjustment component for adjusting the distance between the two moving blocks 5 is installed inside the support plate body 1. Ropes 6 are fixedly connected to the bottom surface of the moving blocks 5, and hooks for hoisting components 7 are fixedly connected to the ends of the ropes 6. A tightening component is provided between the two ropes 6. The distance between the two moving blocks 5 can be adjusted by the adjustment component, thereby adjusting the position of the moving blocks 5 and the ropes 6. The position of the ropes 6 can be adjusted according to the size and type of the component 7, making it widely applicable. At the same time, the tightening component can tighten the middle of the two ropes 6, making it easier to lift the component 7 while tilting the ropes 6, thereby increasing the stability of the component during hoisting and preventing large swaying during transportation.

[0017] The scheme is further optimized. The main body of the support plate 1 includes two parallel horizontal plates 101. The two horizontal plates 101 pass through the support base 2 and are detachably connected to the support base 2. The two horizontal plates 101 pass through the moving block 5 and are slidably connected to the moving block 5. The adjustment component is located between the two horizontal plates 101.

[0018] Further optimization of the scheme involves adjusting the components, including a rotating cylinder 8 located between and rotatably connected to the two horizontal plates 101. A threaded rod 9 is fixedly connected to the side of the moving block 5 near its rotational side. The threaded rod 9 is located between the two horizontal plates 101 and spaced apart from them. The threaded rod 9 is located inside the rotating cylinder 8 and threadedly engaged with it. Since the threaded rod 9 is threadedly connected to the rotating cylinder 8 and does not rotate with it, when the rotating cylinder 8 rotates, the threaded rod 9 will move horizontally, thereby driving the moving block 5 to move and adjusting the relative position of the two moving blocks 5.

[0019] A further optimized solution includes a rope loop 10 wrapped around the outer side of the middle of the two ropes 6 and a tensioner 11 for tightening the rope loop 10. The tensioner 11 is fixedly connected to either rope 6. Tightening the rope loop 10 by the tensioner 11 brings the middle of the two ropes 6 closer together. While lifting the lifting member 7, the ropes 6 tilt, and the two ropes are nearly symmetrical. The horizontal components of the ropes 6 cancel each other out, forming a lateral constraint that effectively suppresses the swing of the lifting member. The tilt angle increases the tension of the ropes 6, allowing for a more even distribution of the load and a higher tolerance for the center of gravity deviation of the lifting member 7. Even if the center of gravity is slightly off, balance can be maintained by adjusting the tension.

[0020] The design is further optimized by providing through holes for the support base 2 and the horizontal plate 101, with the horizontal plate 101 passing through the support base 2. Bolts 12 are threaded onto the support base 2 and the horizontal plate 101, respectively, and abut against the horizontal plate 101. The abutment of the bolts 12 against the horizontal plate 101 limits the position of the support base 2. When the hoisting work is completed and the hoisting bracket needs to be folded up for storage, simply rotating the bolts 12 removes the limitation on the support base 2, facilitating the removal of the mounting base 2 and the support frame 3, reducing the footprint and facilitating storage.

[0021] The working process of this utility model is as follows: During use, the position of the rope 6 is adjusted according to the size of the lifting component 7 and the lifting position. By rotating the drum 8, since the threaded rod 9 is threadedly engaged with the drum 8 and does not rotate with it, the drum 8 will drive the threaded rod 9 to move horizontally along its axis during rotation, thereby driving the moving block 5 and the rope 6 to move, thus completing the adjustment of the rope 6's position. Then, the hook and lifting component 7 are installed together, and the rope loop 10 is tightened by the tensioner 11, bringing the middle of the two ropes 6 closer together. While lifting the lifting component 7, the ropes 6 are tilted, thereby reducing swaying during transport.
