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

[0002] Lifting slings are crucial tools used in lifting operations to connect lifting equipment to the object being lifted, bear loads, and ensure safe lifting. They are diverse in type and widely used, including metal slings and synthetic fiber slings. Metal slings, with their high strength and load-bearing capacity, are widely used in heavy-duty lifting. However, existing lifting slings typically connect to the object via hooks. When lifting hollow cylinders such as steel coils, this connection is inconvenient, sometimes requiring the use of steel cables or other supporting structures to limit the object's position. This process is complex and cumbersome, thus necessitating a lifting sling that is convenient to use and structurally stable. Utility Model Content

[0015] 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.

[0016] 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.

[0017] Reference Figure 1-2 This utility model provides a lifting sling, including an installation cylinder 1. A first moving rod 2 and a second moving rod 3 are slidably connected inside the installation cylinder 1. The first moving rod 2 has a groove 4, and the second moving rod 3 has a sliding protrusion 5 on the side near the first moving rod 2, which is slidably located within the groove 4. Hook plates 6 are fixedly connected to the bottom of the first moving rod 2 and the second moving rod 3, respectively. A control component for controlling the movement of the first moving rod 2 and the second moving rod 3 is installed above the installation cylinder 1. Limiting components are fixedly connected to the installation cylinder 1, located on both sides of the hook plates 6. The lifting sling body is simply placed on top of the cylindrical cargo to be lifted, and the lifting device lifts the sling. The control component then controls the first moving rod 2 and the second moving rod 3 to move towards the center, thereby moving the two hook plates 6 towards the cargo. The hook plates 6 then move to the inner wall of the cargo to clamp it, facilitating lifting. The limiting components can provide auxiliary limiting on both sides of the cargo after lifting, increasing the stability of the cargo during the lifting process.

[0018] The scheme is further optimized. The control component includes a mounting block 7 located above the mounting cylinder 1. The top of the mounting block 7 has a lifting hole. Support seats 8 are fixedly connected to the first moving rod 2 and the second moving rod 3, respectively. A connecting rod 9 is rotatably connected between the support seats 8 and the mounting block 7. A sleeve 10 is fixedly connected above the mounting cylinder 1, and a sliding column 11 is fixedly connected to the bottom surface of the mounting block 7, with the bottom end of the sliding column 11 located inside the sleeve 10. The mounting block 7 is lifted by a lifting device, causing it to move upwards. This upward movement of the mounting block 7 drives the first moving rod 2 and the second moving rod 3 to move towards the center position via the two connecting rods 9, thereby causing the hook plate 6 to lift the goods. During the lifting process, the goods exert a downward force on the hook plate 6 due to gravity, causing the two hook plates 6 to tend to move towards the center position via the connecting rods 9, thus enhancing the stability of the lifting.

[0019] In a further optimized design, a threaded rod 12 is fixedly connected to the bottom surface of the mounting cylinder 1. A baffle 13 is installed at the bottom of the mounting cylinder 1, and a threaded cylinder 14 is rotatably connected to the top surface of the baffle 13. The bottom end of the threaded rod 12 is located inside the threaded cylinder 14 and is threadedly engaged with it. A limiting cylinder 15 is fixedly connected to the bottom surface of the mounting cylinder 1, and a limiting rod 16 is fixedly connected to the top surface of the baffle 13. The top end of the limiting rod 16 slides within the limiting cylinder 15. By rotating the threaded cylinder 14, the distance between the baffle 13 and the mounting cylinder 1 can be adjusted, thereby adjusting the relative height between the hook plate 6 and the cargo according to the lifting position of the cargo, so that the hook plate 6 is aligned with the lifting position of the middle of the cargo.

[0020] The scheme is further optimized by including fixed posts 17 located on both sides of the mounting cylinder 1 and fixedly connected to the mounting cylinder 1. The fixed posts 17 are perpendicular to the first moving rod 2. Sliding sleeves 18 are provided on the fixed posts 17, and limiting plates 19 are fixedly connected to the bottom surface of the sliding sleeves 18. The two limiting plates 19 are arranged in parallel. By adjusting the position of the two sliding sleeves 18, the position of the two limiting plates 19 is adjusted, and the two limiting plates 19 are used to prevent the goods from shaking during the lifting process.

[0021] In a further optimized design, a bolt 20 is threaded onto the sliding sleeve 18. The bolt 20 penetrates the sliding sleeve 18 and abuts against the fixed post 17. The bolt 20 abuts against the fixed post 17, increasing the friction between the sliding sleeve 18 and the fixed post 17 and assisting the fixed post 17 in positioning.

[0022] To further optimize the design, a rubber pad 21 is fixedly connected to the bend of the hook plate 6. This increases friction while preventing wear between the hook plate 6 and the goods.

[0023] The working process of this utility model is as follows: When in use, the lifting sling is placed on the goods to be lifted, and the installation cylinder 1 is lowered so that the baffle 13 abuts against the goods. During the lowering process, the first moving rod 2 and the second moving rod 3 will move outward, thereby opening the two hook plates 6 so that they face the inner wall of the cylindrical goods. Then, the installation cylinder 1 is lifted upward. When the lifting device lifts the installation block 7, it pulls the two connecting rods 9, thereby moving the first moving rod 2 and the second moving rod 3 to the middle position, thereby driving the two hook plates 6 to move closer to the goods. Thus, the goods can be lifted by using the hook plates 6. At the same time, the position of the two sliding sleeves 18 is adjusted so that the two limiting plates 19 are located on both sides of the goods, which can enhance the stability of the goods during the lifting process.

[0025] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model.
