DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0021] A permanent magnet chuck sling structure aims to ensure a stable and reliable connection between the permanent magnet chuck and the lifting equipment during the lifting process.

[0022] When the existing permanent magnet chuck slings are in use, the connecting ring on the crane is connected to the hook sling on the permanent magnet chuck and then lifted. During the lifting process, if there is severe vibration or impact, the connecting ring may shift from the hook sling, leading to the problem of the permanent magnet chuck falling off. Please refer to Figures 1 - 4 , this embodiment provides a permanent magnet chuck sling structure, including a chuck body 1. During the lifting operation, by pressing the switch, the control system of the crane will turn on the power supply of the chuck body 1 and start a vacuum pump or other gas extraction device to generate an adsorption force. This adsorption force fixes the object on the chuck body 1, enabling the crane to stably move the object to the required position. A sling 2 is provided at the top of the chuck body 1. The sling 2 is assembled by hinging the bottom half ring 31 and the upper half ring 32. One end of the bottom half ring 31 and the upper half ring 32 is hinged, so that the sling 2 can be opened to connect to the crane connecting ring and can also be closed to block the crane connecting ring, further reducing the occurrence of the falling-off phenomenon.

[0023] Reference Figures 2 - 4As shown in the figure, when the existing permanent magnet chuck lifting ring is in use, the connecting ring on the crane is connected to the hook lifting ring on the permanent magnet chuck and then lifted. During the lifting process, if there is a violent vibration or impact, the connecting ring may shift from the hook lifting ring, resulting in the problem of the permanent magnet chuck falling off. To improve the connection reliability between the two, the following settings are made. An assembly mechanism 3 for connecting the crane connecting ring is provided on the outer wall of the lifting ring 2. The assembly mechanism 3 includes two rectangular blocks 33 fixed on the end faces of the bottom half ring 31 and the upper half ring 32. An adsorption component 34 for enhancing the connection tightness between the two rectangular blocks 33 is arranged between the two rectangular blocks 33. The adsorption component 34 includes two magnets 341 fixed on the opposite sides of the two rectangular blocks 33, and the two magnets 341 attract each other. After the bottom half ring 31 and the upper half ring 32 are opened and the connecting ring on the crane is inserted, the bottom half ring 31 and the upper half ring 32 are closed so that they attract each other through the two magnets 341 to achieve preliminary closure. A rectangular groove is opened inside one of the rectangular blocks 33. Two outer plates 355 are symmetrically arranged inside the rectangular groove. Two clamping blocks 356 are fixedly connected to the end faces of the two outer plates 355. Two clamping slots 357 are symmetrically opened on both sides of the other rectangular block 33. A reinforcing sleeve is fixedly connected to the inner wall of the clamping slot 357. The inner wall of the reinforcing sleeve is in close contact with the outer wall of the clamping block 356. The material of the reinforcing layer includes but is not limited to rubber and latex materials. The reinforcing sleeve significantly enhances the clamping firmness between the clamping block 356 and the clamping slot 357 by increasing friction, absorbing impact, enhancing sealing performance, improving durability and adaptability. A power component 35 for driving the two clamping blocks 356 to move towards each other and insert into the two clamping slots 357 to form a fixation is arranged inside the rectangular groove. The power component 35 includes a lead screw 352 rotating inside the rectangular groove. A rotating handle 351 is fixedly connected to the top of the lead screw 352. A sliding plate 353 is threadedly connected to the outer wall of the lead screw 352. Two movable rods 354 are hinged to both ends of the sliding plate 353. The two movable rods 354 are hinged to the two outer plates 355. After preliminary closure, the rotating handle 351 is rotated to make the lead screw 352 rotate. The rotation of the lead screw 352 causes the sliding plate 353 to move upward on the outer wall of the lead screw 352, causing the movable rods 354 to drive the outer plates 355 to move towards each other, and further causing the clamping block 356 to insert into the clamping slot 357 for fixation, realizing the fixed connection between the two rectangular blocks 33. When the connecting ring on the crane and the hook lifting ring 2 on the suction cup body 1 form a closed connection relationship, the closed ring-to-ring connection provides a more stable fixing method, reducing the risk of falling off caused by the relative movement between the connecting ring and the lifting ring 2, and thus reducing the problem of the suction cup body 1 falling off. Limiting components for enabling the outer plates 355 to move directionally along the inner wall of the rectangular groove are arranged at the bottoms of the two outer plates 355. The limiting components include limiting blocks fixed at the bottoms of the outer plates 355. Limiting grooves are opened on the inner bottom wall of the rectangular groove, and the limiting blocks slide left and right along the length direction of the limiting grooves.

[0024] Reference Figure 2As shown, the inner top wall of the upper half ring 32 is fixedly connected with an n-shaped snap ring block 4, and the inner wall of the n-shaped snap ring block 4 is bonded and fixed with a friction-increasing patch. The material of the friction-increasing patch includes but is not limited to polyurethane, which has good elasticity and friction characteristics, is suitable for occasions with greater pressure and friction, and can also maintain stable performance in a wider temperature range. After the crane connecting ring is inserted into the lifting ring 2, the position of the connecting ring is fixed in the n-shaped snap ring block 4, and the friction between the contact surfaces is increased by the setting of the friction-increasing patch. This friction helps to prevent the crane connecting ring from sliding or moving during operation, and the stability of the crane connecting ring is improved, thereby effectively reducing the amplitude of the suction cup body 1 shaking in the air, reducing the potential risks and unstable factors caused by shaking, making the movement of the suction cup body 1 in the air more controlled, thereby improving the safety and reliability of the overall operation.

[0025] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
