[0022] 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.

[0023] This utility model provides a steel plate hoisting device, such as... Figures 1-3 As shown, the main frame plate 1 is connected to the top of the main frame plate 1 with several steel wire ropes 2. The top ends of the steel wire ropes 2 are all connected to the same lifting ring 3. Two lifting components 4 are installed at both ends of the main frame plate 1. The bottom ends of the two lifting components 4 are connected to clamping components 5 by chains 6. The clamping components 5 include a U-shaped clamping plate 51. The bottom plate of the clamping plate 51 has two through locking holes 52. Each locking hole 52 is threaded with a locking bolt 53.

[0024] In use, several steel wire ropes 2 connected to the top of the main frame plate 1 are uniformly connected to lifting rings 3 at their top ends. This design not only enhances the stability of the lifting but also ensures the even distribution of force during the lifting process, effectively avoiding the risk of steel plate swaying and falling off. Simultaneously, the lifting assembly 4 installed on the main frame plate 1 is connected to the clamping assembly 5 via a chain 6, making the entire lifting process more flexible and controllable. The U-shaped clamping plate 51 in the clamping assembly 5, in conjunction with the locking holes 52 and locking bolts 53, can firmly clamp the steel plate, preventing it from sliding or falling off during the lifting process, thereby ensuring the safety and reliability of the lifting operation. In summary, the steel plate lifting device of this utility model, with its unique design and excellent performance, significantly improves the efficiency and safety of steel plate lifting, providing strong technical support for lifting operations.

[0025] In this embodiment, the wire ropes 2 are arranged at an angle, with the bottom ends of several wire ropes 2 respectively hinged to the top two ends of the main frame plate 1, the top ends of several wire ropes 2 all hinged to the lifting rings 3, and the bottom ends of several wire ropes 2 all hinged to the main frame plate 1. The angled arrangement of the wire ropes can better distribute the forces generated during the hoisting process, reduce the force concentration on the main frame plate and the lifting rings, thereby extending the service life of the device; at the same time, the hinged connection allows the wire ropes to have a certain amount of room for movement during the hoisting process, accommodating the slight movement of the steel plate during hoisting, and avoiding damage that may be caused by rigid connections.

[0026] Specifically, a gasket 54 is installed on the top inner wall of the clamping plate 51. This design effectively protects the steel plate being hoisted, as the gasket prevents the steel plate from being damaged due to excessive clamping; at the same time, the gasket also serves as an anti-slip measure, ensuring that the steel plate will not slip out of the clamping plate during hoisting.

[0027] Furthermore, the lifting assembly 4 includes fixed plates 41. Fixed plates 41 are welded to both ends of the top of the main frame plate 1. Each fixed plate 41 has two through threaded holes 411 on its top surface, and each threaded hole 411 is threaded with an adjusting threaded rod 42. This design makes the lifting assembly both robust and easy to adjust. By rotating the adjusting threaded rod 42, the height of the clamping assembly 5 can be easily adjusted to accommodate the lifting needs of steel plates of different specifications and thicknesses.

[0028] Furthermore, a connecting ring 44 is installed at the bottom end of the adjusting threaded rod 42, and the connecting ring 44 is connected to the top end of the chain 6. The bottom end of the chain 6 is welded and fixed to the top of the clamping plate 51. This design achieves a flexible connection between the lifting assembly and the clamping assembly. The chain has a certain degree of flexibility and strength, which can adapt to the slight movement of the lifting assembly during the adjustment process, while ensuring that the clamping assembly 5 stably clamps the steel plate.

[0029] Furthermore, the top of the main frame plate 1 has multiple through holes, the same number as the adjusting threaded rods 42. The top of the adjusting threaded rod 42 slides through the corresponding through hole and then threaded through the threaded hole 411. This design allows the adjusting threaded rods to be securely mounted on the main frame plate, while facilitating their vertical movement and rotational adjustment. The presence of the through holes also reduces the weight of the main frame plate and improves the overall efficiency of the hoisting device.

[0030] Furthermore, a locking nut 43 is installed at the top of the adjusting threaded rod 42. This design ensures that the adjusting threaded rod can be firmly locked onto the main frame plate after adjustment, and will not loosen due to vibration or external force during hoisting. The presence of the locking nut improves the safety and stability of the hoisting device.

[0031] Furthermore, the lifting ring 3 is lifted using lifting equipment. There are four wire ropes 2, arranged in groups of two. The bottom ends of the two groups of wire ropes 2 are hinged to both ends of the main frame plate 1 and are symmetrically arranged. This design ensures that the lifting device remains balanced and stable during lifting, preventing tilting or swaying caused by insufficient wire ropes or improper arrangement. Simultaneously, the symmetrical arrangement of the four wire ropes enhances the load-bearing capacity and safety of the lifting device.

[0032] When using the steel plate hoisting device of this utility model, first assemble the various components of the hoisting device as shown in the attached drawings. Ensure that the main frame plate 1, wire rope 2, lifting ring 3, lifting assembly 4 including fixing plate 41, adjusting threaded rod 42, locking nut 43, connecting ring 44, chain 6, and clamping assembly 5 including clamping plate 51, locking hole 52, locking bolt 53, washer 54, etc., are all correctly installed and securely connected.

[0033] According to the specifications and thickness of the steel plate to be hoisted, the height of the clamping assembly 5 is adjusted by rotating the adjusting threaded rod 42. During the adjustment process, the gap between the clamping plate 51 and the steel plate can be observed to ensure that the clamping plate 51 can fit tightly against the steel plate without generating excessive pressure. After the adjustment is completed, the adjusting threaded rod 42 is locked onto the main frame plate 1 using the locking nut 43 to prevent the adjusting threaded rod from loosening due to vibration or external force during hoisting.

[0034] Move the lifting device above the steel plate to be lifted, aligning the opening of the clamping plate 51 with the steel plate. Then, place the end of the steel plate inside the clamping plate 51, and tighten the locking bolt 53 so that the end of the locking bolt 53 abuts against the steel plate, thereby firmly clamping the clamping plate 51 onto the steel plate. The presence of the gasket 54 protects the steel plate from damage and prevents it from sliding or falling off during lifting.

[0035] The entire lifting device and the clamped steel plate are lifted using lifting equipment such as cranes or hoists via lifting rings 3. Because the wire rope 2 is inclined and its upper end is hinged to the lifting ring 3, while its lower end is hinged to the main frame plate 1, stability and even force distribution during the lifting process are ensured. During lifting, the lifting assembly 4 is connected to the clamping assembly 5 via a chain 6, making the entire lifting process more flexible and controllable. The chain 6 has a certain degree of flexibility and strength, capable of accommodating minor movements of the lifting assembly during adjustment, while ensuring that the clamping assembly 5 stably holds the steel plate.

[0036] After moving the hoisting device and the clamped steel plate to the target position, slowly lower the steel plate. During the placement process, the position of the steel plate can be finely adjusted by adjusting the height of the clamping assembly 5 using the lifting assembly 4 to ensure that the steel plate is accurately placed in the predetermined position. After placement, loosen the locking bolt 53 and remove the clamping plate 51 from the steel plate to complete the entire hoisting operation.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. 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 preferred examples and are not intended to limit the utility model.
