Description

Technical Field

[0001] This utility model relates to the technical field of waste lithium battery recycling equipment, and more specifically, to an adjustable hoisting mechanical claw for waste lithium batteries. Background Technology

[0002] The waste lithium battery pack contains several waste lithium battery packs. After the waste lithium battery pack is used up, it is first tested and discharged. Then, the several waste lithium battery packs inside the waste lithium battery pack need to be disassembled and crushed one by one. In the actual disassembly process, the wires of several waste lithium battery packs are first disconnected. Then, each waste lithium battery pack is lifted one by one with a pry bar. Finally, the studs around the bottom of the hoist are screwed into the screw holes on both sides of the waste lithium battery pack for hoisting. Each waste lithium battery pack is hoisted onto the conveyor belt and transported to the crusher for crushing.

[0003] The following problems exist in the actual hoisting process: First, the existing studs and collars are hinged, and the collars and hooks are also hinged. Although the two hinged structures facilitate the in-plane rotation of the studs, the degree of freedom is large, which means that during the hoisting process, workers need to hold the ropes throughout to ensure the stability and safety of the hoisting, resulting in high labor intensity and insufficient hoisting stability; Second, each hoisting operation requires screwing in and out four studs into the screw holes on both sides of the waste lithium battery pack, which takes a long time and affects the hoisting efficiency of the waste lithium battery pack. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable lifting claw for waste lithium batteries. This lifting claw can be adjusted to fit the length of the waste lithium battery pack, while having good lifting stability. It does not require repeated screwing in and out, thus improving the lifting efficiency of waste lithium batteries.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An adjustable lifting claw for waste lithium batteries includes a waste lithium battery pack. The waste lithium battery pack has two L-shaped through holes on both sides of its outer shell for lifting. The lifting claw comprises four identical claw bodies, the upper ends of which are connected to the lower surface of an upper lifting plate via pull rods. The lifting plate consists of two symmetrical parts connected by two parallel telescopic rods, which are limited by locking bolts. Parallel hanging rings are provided at both ends of the upper surface of the lifting plate, and hooks are attached to these rings. The hooks are connected to the lower end of the lifting head via ropes.

[0007] As a further optimization of this solution, the claw body includes an L-shaped clamping plate and an L-shaped connecting seat. The front end of the horizontal section of the L-shaped connecting seat is rotatably connected to the rear side of the upper end of the vertical section of the L-shaped clamping plate via a rotating shaft. The cross-section of the L-shaped clamping plate is semi-circular, and the horizontal section of the L-shaped clamping plate is rotatably inserted into the lower L-shaped through hole.

[0008] As a further optimization of this solution, the vertical section of the L-shaped connector is machined with a through hole, and a push rod passes through the through hole. The front and rear ends of the push rod are equipped with limiting baffles. A return spring is fitted on the push rod body between the limiting baffle located outside the L-shaped connector and the outer side of the vertical section of the L-shaped connector. A rectangular blind groove is opened on the upper side of the push rod body, and a rectangular through groove is opened on the upper surface of the horizontal section of the L-shaped connector. The rectangular through groove passes through the through hole on the surface of the vertical section of the L-shaped connector. An L-shaped insert plate is inserted into the rectangular through groove. The vertical section of the L-shaped insert plate is aligned downward and inserted into the rectangular blind groove on the upper side of the push rod body to limit the push rod.

[0009] As a further optimization of this solution, an extension plate is provided behind the horizontal section of the L-shaped insert plate, and a guide rod passes through the surface of the extension plate. A limit baffle is fixed at the upper end of the guide rod.

[0010] As a further optimization of this solution, the top rod is pressed inward by the outer limiting baffle to tighten the inner side of the L-shaped card plate.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0012] In this utility model, the left and right lifting plates are connected by two parallel telescopic connecting rods. The connection between the tie rod and the claw body replaces the traditional stud and collar structure, which makes the stability during the lifting process better. It does not require manual assistance throughout the process and can lift the waste lithium battery packs more safely. The split left and right lifting plates can be adjusted to fit the length of the waste lithium battery pack.

[0013] This invention utilizes a claw structure composed of an L-shaped clamping plate and an L-shaped connecting seat, which replaces the traditional stud structure. This claw structure is fitted into the L-shaped through hole on the existing waste lithium battery pack shell, thus fixing both sides of the waste lithium battery pack. The L-shaped clamping plate and the L-shaped connecting seat are limited by an L-shaped insert plate inserted into the rectangular blind groove of the top rod. The insertion and disassembly are quick and convenient, significantly improving the hoisting efficiency of waste lithium battery packs. Attached Figure Description

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0020] To address the existing issues of hinged connections between studs and collars, and also between collars and lifting hooks, while these two hinged structures facilitate in-plane rotation of the studs, the large degree of freedom necessitates workers to continuously support the ropes during hoisting to ensure stability and safety. This results in high labor intensity, insufficient hoisting stability, and the time-consuming process of screwing in and out four studs into the screw holes on both sides of the waste lithium battery pack for each hoisting operation, thus affecting the hoisting efficiency of waste lithium battery packs.

[0021] like Figure 1 As shown, this application includes a waste lithium battery pack 1. The waste lithium battery pack 1 has two L-shaped through holes 11 for hoisting on both sides of its outer shell. The hoisting mechanical claw includes four claw bodies with the same structure. The upper end of each claw body is connected to the lower surface of the upper hoisting plate 3 through a pull rod 2. The hoisting plate 3 consists of two symmetrical parts and the two symmetrical parts are connected by two parallel telescopic connecting rods 4. The telescopic connecting rods 4 are limited by locking bolts 5. Parallel hanging rings 6 are provided at both ends of the upper surface of the hoisting plate 3. Hooks 7 are fastened on the hanging rings 6 and connected to the lower end of the hoisting head through ropes 8.

[0022] like Figure 2 As shown, the claw body includes an L-shaped clamping plate 10 and an L-shaped connecting seat 9. The front end of the horizontal section of the L-shaped connecting seat 9 is rotatably connected to the rear side of the upper end of the vertical section of the L-shaped clamping plate 10 via a rotating shaft. The cross-section of the L-shaped clamping plate 10 is semi-circular. The horizontal section of the L-shaped clamping plate 10 is rotatably inserted into the lower L-shaped through hole 11.

[0023] like Figure 3 and Figure 4As shown, the vertical section of the L-shaped connecting seat 9 has a through hole, through which a push rod 12 passes. Limiting baffles are provided at both the front and rear ends of the push rod 12. A return spring 13 is fitted on the push rod 12 between the limiting baffle outside the L-shaped connecting seat 9 and the outer side of the vertical section of the L-shaped connecting seat 9. A rectangular blind groove 16 is opened on the side of the push rod 12, and a rectangular through groove is opened on the upper surface of the horizontal section of the L-shaped connecting seat 9. The rectangular through groove passes through the through hole on the surface of the vertical section of the L-shaped connecting seat 9. An L-shaped insert plate 15 is inserted into the rectangular through groove. The vertical section of the L-shaped insert plate 15 is aligned downward and inserted into the rectangular blind groove 16 on the side of the push rod 12 to limit the push rod 12. An extension plate is provided behind the horizontal section of the L-shaped insert plate 15. A guide rod 14 passes through the surface of the extension plate, and a limiting baffle is fixed at the upper end of the guide rod 14.

[0024] Specifically, during hoisting, loosen the locking bolts 5 of the telescopic connecting rod 4 to allow the left and right hoisting plates 3 to move freely. In the initial state, the L-shaped clamping plate 10 is as follows: Figure 4 As shown, the L-shaped connector 9 can rotate freely around it. The L-shaped clamping plate 10 is inserted into the L-shaped through hole 11 at the corresponding position. At this time, the top rod 12 is pressed inward through the outer limiting baffle, pressing against the inner side of the L-shaped clamping plate 10. At the same time, the vertical section of the L-shaped insert plate 15 is inserted downward into the rectangular blind groove 16 on the side of the top rod 12 to limit the top rod 12 and achieve the clamping effect. After clamping is completed on all four sides, the work of hoisting the waste lithium battery pack 1 can begin. After reaching the position of the conveyor belt, the L-shaped insert plate 15 can be pulled up along the guide rod 14. The top rod 12 springs outward under the elastic force of the return spring 13, so that the L-shaped clamping plate 10 can rotate freely again. The L-shaped clamping plate 10 is pulled out from the L-shaped through hole 11, and the waste lithium battery pack 1 is put down onto the conveyor belt.
