[0002] Cotton rolls are a common raw material in textiles, hygiene products, construction, and other fields, and their storage, transportation, and production processes require frequent hoisting operations. Currently, the hoisting tools used for cotton rolls in the industry are mainly divided into three categories: traditional binding hoisting tools, fixed-structure claw hoisting tools, and vacuum suction hoisting tools.

[0003] However, current hoisting tools have the following shortcomings in actual use: 1. Traditional binding lifting tools are cumbersome to operate, inefficient, and difficult to control the binding force, which can easily lead to deformation, slippage, or surface wear of the cotton roll. 2. Fixed-structure claw-type lifting devices have fixed claw specifications and poor versatility. The one-piece molded structure has high maintenance costs and lacks a rotating mechanism, resulting in insufficient flexibility. 3. Vacuum adsorption type lifting devices have high requirements for the surface of cotton cloth, are prone to adsorption failure, have limited load-bearing capacity, are greatly affected by the environment, and have poor stability; 4. Existing adjustable lifting devices have rudimentary adjustment structures, lack precise scales, are inconvenient to disassemble, and have rotating structures that are prone to jamming and have poor smoothness.

Detailed Implementation

[0017] like Figure 1 and Figure 2 As shown, a cotton roll lifting device includes a top plate 1, a bottom plate 2, a central column 3, and lifting claws. The top plate 1, bottom plate 2, and central column 3 are all made of high-strength stainless steel, providing high structural strength and corrosion resistance. The upper end face of the central column 3 is fixedly connected to the top plate 1 by welding, ensuring a firm and stable connection. The lower end face of the central column 3 is detachably connected to the base plate 2. The top plate 1 and the base plate 2 are both perpendicular to the central column 3 and coaxially arranged to ensure that the overall force of the lifting device is balanced. A rotating cylinder 4 is sleeved on the outside of the central column 3. The rotating cylinder 4 is made of wear-resistant alloy steel. The inner wall of the rotating cylinder 4 is reserved with a gap from the outer wall of the central column 3 to avoid friction during rotation. The outer wall of the rotating cylinder 4 is detachably connected to the lifting claw. A lifting ring 5 is provided in the center of the upper end face of the top plate 1. The lifting ring 5 is welded and fixed to the top plate 1. The inner wall of the lifting ring 5 is provided with anti-slip texture to facilitate connection with the hook of the lifting equipment.

[0018] As shown in Figure 2, the preferred solution is that threaded mounting holes 6 are provided at the axial center of the center column 3 and the base plate 2. The specifications of the threaded mounting holes 6 are compatible with the mounting bolts 7. The mounting bolts 7 are internal hexagonal head bolts, and their threaded parts are threaded into the threaded mounting holes 6. By tightening the mounting bolts 7, the base plate 2 and the center column 3 can be tightly connected and fixed. When disassembling, it is only necessary to loosen the bolts to separate them, which is convenient to operate.

[0019] As shown in the preferred embodiment 3, an annular groove 10 is provided on the base plate 2, and the cross-section of the annular groove 10 is T-shaped. The bottom end face of the rotating cylinder 4 is provided with an annular rail 9, and the cross-sectional shape of the rail 9 matches the groove 10. The rotating cylinder 4 is engaged with the groove 10 through the rail 9. After engagement, a small gap is left between the two to ensure that the rotating cylinder 4 can rotate freely and flexibly around the axis of the central column 3 without jamming. The structure of the rotating cylinder 4 is adopted to allow the lifting claw to rotate freely, so as to prevent problems such as tangling of the lifting rope during the hoisting process.

[0020] As shown in the preferred embodiment 3, the outer wall of the central column 3 is uniformly provided with 3-4 rotating rollers 8. The rotating rollers 8 adopt a bearing-type structure, and one end of them is rotatably connected to the lower end face of the top plate 1 through a bearing seat. The rotating rollers 8 are symmetrically distributed in a ring around the axis of the central column 3, and the included angle between adjacent rotating rollers 8 is equal. The rotating cylinder 4 is sleeved on the outer wall of the central column 3, and the inner wall of the rotating cylinder 4 is in rolling contact with the outer wall of the rotating rollers 8. Through the rolling support of the rotating rollers 8, the friction force when the rotating cylinder 4 rotates can be reduced, and the rotation smoothness can be improved.

[0021] As shown in Figure 4, the preferred embodiment includes a fixed plate 13, a rotating sleeve plate 14, and a telescopic lifting plate 15. All three components are made of high-strength aluminum alloy, which is lightweight yet strong enough to meet lifting requirements. The fixed plate 13 is detachably connected to the outer wall of the rotating cylinder 4. The other end of the fixed plate 13 is rotatably connected to the rotating sleeve plate 14, and the other end of the rotating sleeve plate 14 is fitted with the telescopic lifting plate 15 with a clearance, allowing for flexible adjustment of the extension length of the telescopic lifting plate 15.

[0022] As shown in Figure 4, the outer wall of the rotating cylinder 4 is provided with 6-8 connecting plates 11, which are symmetrically distributed in a ring around the outer wall of the rotating cylinder 4, with equal spacing between adjacent connecting plates 11. The end of the fixing plate 13 is inserted between the two sets of connecting plates 11. Bolt holes are correspondingly opened on the connecting plates 11 and the fixing plate 13. The connecting bolts 12 pass through the bolt holes and are locked in place with nuts, realizing a detachable connection between the lifting claws and the rotating cylinder 4. The number of lifting claws can be selectively installed according to the actual needs of the site (usually 2-4 claws are installed) to accommodate the lifting of cotton rolls of different weights and diameters, ensuring uniform force distribution.

[0023] As shown in the preferred embodiment 4, the end of the rotating sleeve 14 is inserted between two sets of fixed plates 13. The rotating sleeve 14 and the fixed plates 13 are respectively provided with shaft holes. The rotating shaft 16 is set through the shaft hole, and the two ends of the rotating shaft 16 are limited and fixed by snap rings. The rotating shaft 16 and the shaft hole are fitted with a clearance fit, so that the rotating sleeve 14 can rotate flexibly and freely around the axis of the rotating shaft 16, which is convenient for adjusting the clamping angle of the lifting claw.

[0024] As shown in the preferred embodiment 5, the ends of the telescopic hanging plate 15 and the rotating sleeve plate 14 are fitted with a clearance, and the telescopic hanging plate 15 can freely extend and retract along the axial direction of the rotating sleeve plate 14; the other end of the telescopic hanging plate 15 is integrally formed with an L-shaped hook, and the inner side of the L-shaped hook is provided with a rubber anti-slip pad, which can avoid damage to the surface of the cotton roll during clamping, and at the same time improve the clamping stability; the side of the telescopic hanging plate 15 is engraved with a scale shaft 17 with millimeter-level precision, which makes it easy for the operator to accurately control the extension length of the telescopic hanging plate 15 and ensure that the clamping positions of multiple claws are consistent.

[0025] As shown in Figure 5, a threaded cylinder 18 is vertically welded to the upper end face of the rotating sleeve 14. The threaded cylinder 18 has an internal thread, and the limiting bolt 19 is threadedly engaged with the internal thread of the threaded cylinder 18. When the telescopic hanging plate 15 is adjusted to the required extension length, the limiting bolt 19 is tightened so that the end of its screw presses tightly against the surface of the telescopic hanging plate 15, thereby locking and fixing the extension distance of the telescopic hanging plate 15 and preventing the telescopic hanging plate 15 from shifting during the hoisting process.
