Detailed Implementation

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] In this embodiment, as Figures 1-5 As shown, the specific design of the above-mentioned key components is described below: A large forging hoisting device includes a lifting ring 1 and a lifting rod 2. A receiving plate 3 is provided below the lifting rod 2. The receiving plate 3 has multiple through-holes 11 running vertically through it. A sliding component 4 is provided on the through-holes 11. A moving plate 5 is provided on the sliding component 4. The end of the moving plate 5 adjacent to the sliding component 4 is vertical, and the end of the moving plate 5 away from the sliding component 4 is inclined. A clamping plate 8 is provided on the end of the moving plate 5 away from the sliding component 4. An extension rod 6 is provided below the receiving plate 3. A chuck 7 is provided below the extension rod 6. The chuck 7 has multiple openings 12. A horizontal square is provided on the inner side of the moving plate 5. The width of the clamping plate 13 is the same as the width of the opening 12, so that the clamping plate 13 and the opening 12 cooperate to achieve locking. First, adjust the position of each sliding component 4 one by one, slide the sliding component 4 near the forging, and then drive the moving plate 5 to clamp the forging through each sliding component 4. Then, the clamping plate 13 is locked on the opening 12, further fixing the position of the moving plate 5, so that the moving plate 5 can better clamp the forging. The design of the moving plate 5 with one end vertical and the other end inclined not only facilitates the connection and enhances the stability of the connection, but also further clamps the forging, forming a state similar to a human hand holding it, which can better grasp the forging for lifting.

[0024] To enhance the stability of the forging during lifting, a propulsion assembly 9 is provided on the moving plate 5. The propulsion assembly 9 further enhances the stability and firmness of the forging during lifting. The propulsion assembly 9 includes a sleeve 901, a through rod 902, a through hole 903, a bolt 904, and a contact plate 905. The sleeve 901 is located on the outer side of the moving plate 5 and has a through-hole. The through rod 902 is slidably disposed inside the sleeve 901. The through hole 903 is located around the sleeve 901 and the through rod 902. The bolt 904... A 904 is inserted through the column sleeve 901 and the through rod 902. A contact plate 905 is located on one end of the through rod 902. By recommending the depth of the through rod 902 on the column sleeve 901, the forgings are pressed together, further enhancing the stability of the moving plate 5 when it picks up the forgings. The contact plate 905 directly contacts the forgings, and several contact plates 905 press together to fix the forgings. The depth of the through rod 902 on the column sleeve 901 is limited by the through bolt 904. This design further enhances the firmness and stability of the forging hoisting.

[0025] To accommodate forgings of different sizes and enhance the versatility of forging hoisting, the sliding assembly 4 includes a sliding chamber 401, a cover plate 402, pin holes 403, and a pin shaft 404. The sliding chamber 401 is positioned above the through-hole 11 and is an open shape extending vertically. The cover plate 402 is positioned above the moving plate 5 and slides above the sliding chamber 401. The pin holes 403 are located on both sides of the sliding chamber 401 and on both sides of the moving plate 5 adjacent to the cover plate 402. The pin shaft 404 passes through the pin holes 403 and... On the movable plate 5, the width of the cover plate 402 on the movable plate 5 is greater than the width of the sliding chamber 401, while the width of the movable plate 5 is less than the width of the sliding chamber 401. In this way, the cover plate 402 is above the sliding chamber 401 to prevent the movable plate 5 from falling, so that the movable plate 5 can rest on the sliding chamber 401. The position of the movable plate 5 can be adjusted by dragging the cover plate 402. Finally, the position of the movable plate 5 is limited by the pin 404 passing through the pin hole 403 and the movable plate 5 to prevent the movable plate 5 from shaking.

[0026] To better achieve the clamping effect of the moving plate 5 on the forging, the openings 11 are radially distributed around the lifting rod 2. This radial distribution provides multiple clamping contact points, increases the contact range, and enhances the clamping force. The chuck 7 is disc-shaped, which facilitates the radial distribution of the moving plate 5 and better achieves the mutual engagement of the disc opening 12 and the chuck 13. Multiple supplementary lights 10 are provided on the outer side of the moving plate 5 to enhance the light source in adverse environments. The clamping plate 8 and the contact plate 905 are both made of rubber to increase friction, enhance the clamping force, and increase the stability and firmness during hoisting. This design avoids swaying when using lifting ropes, achieves stable clamping and hoisting of forgings, improves the safety and efficiency of hoisting, and enhances the stability and service life of the hoisting device.

[0027] That which is not described in detail in the present description is part of the prior art known to a person skilled in the art.

[0028] The above is only the preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any person skilled in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification made to the above embodiments without departing from the technical solution of the present application, according to the technical essence of the present application, still belong to the protection scope of the technical solution of the present application.
