[0042] REFERENCE Figures 1-5As shown, a non-powered lithium battery module grabbing device, including a lifting ring 1, which is a standard ring for hanging on the hook of a crane. The lifting ring 1 is vertically welded on a pull rod 2. The pull rod 2 is a cylinder with a circular hole at the bottom and extends outward, and each nut and other movable locking member 3 is inserted and locked to fix each connecting rod. The connecting rod of the connecting rod transmission mechanism 4 has eight pieces, which are four oval first connecting rods 401 and four dart-shaped second connecting rods 402. Each side of the first connecting rod 401 has a fixed hole 403, and one side has two obliquely arranged small holes as oblique holes 404. The second connecting rod 402 has a hole 405 at each end, and there is also a hole at the corner. Two groups of first connecting rods 401 are respectively overlapped and fixed on both sides of the circular hole of the pull rod 2, and four second connecting rods 402 are connected together with movable locking members 3 at the other end hole of the two opposite groups of first connecting rods 401. The distance between the first connecting rod 401 and the second connecting rod 402 is adjustable.

[0043] Referring to Figures 5-7 As shown, the two oblique holes on the first connecting rod 401 are used to fix the limiting assembly one 51 of the limiting mechanism 5, and the limiting assembly two 52 is below the limiting assembly one 51. The limiting assembly three 53 is sleeved on the outer end of the limiting assembly one 51, and is sequentially threaded through the threaded grooves of the limiting assembly three 53 and the limiting assembly one 51 to fix the limiting assembly one 51 and the limiting assembly three 53. The limiting assembly two 52 is a U-shaped clamping groove structure, and a limiting groove 521 is formed at the center of the limiting assembly two 52. The limiting assembly three 53 is a hollow cylindrical structure.

[0044] The limiting assembly one 51 is a combination of a spiral member 510 and a fixed block 511, the side end of the fixed block 511 is provided with a positioning screw groove 512, and the limiting assembly four 54 is screwed into the positioning screw groove 512. The head of the spiral member 510 is a prism structure, which is rotated and clamped into the limiting groove of the limiting assembly two 52. The turning part of the second connecting rod 402 is locked with the movable locking member 3 by inserting and locking the two connecting rods, and the connecting rods are movable. The compression plate 602 and the lock plate 603 of the clamping assembly 60 of the clamping mechanism 6 are tightly locked below the second connecting rod 402 on both sides, the compression plate 602 and the lock plate 603 are overlapped, and the compression plate 602 is placed on the outside. The hook plate 601 is perpendicular to the compression plate 602, and the lock plate 603 is tightly locked. The hook plate 601 has a vertical inner clamping plate 604 below it, which is used to hook and clamp the reinforcing ribs of the lithium battery module. The compression plate 602 and the lock plate 603 are both caliper-shaped structures, and the compression plate 602 has a downward extension in the middle, and a positioning plate 605 perpendicular to the compression plate 602 is arranged at the extension for tightly pressing the reinforcing ribs, so that the module can be effectively prevented from moving.

[0045] By the inner clamping plate block 604 of the hook plate 601 on both sides can be completely clamped into the module reinforcing rib groove, then lifting the clamp, the positioning plate block 605 of the compression plate 602 can be slowly tightened, the inner clamping plate block 604 and the positioning plate block 605 firmly clamp the module reinforcing rib and hook the reinforcing rib groove, effectively prevent the hidden danger of threatening personal safety and damaging products caused by the module shaking off the hook. After the battery module has been moved to the designated position, the device continues to move downward and slowly opens, a limiting assembly one 51 in the connecting rod transmission mechanism rotates downward, and then clamps into the limiting groove of a limiting assembly two 52 below, so that the connecting rod can be locked to fix the entire device. When using such a clamp, only one person is needed to operate, the inner clamping plate block 604 is placed into the reinforcing rib groove, the clamp is lifted, the module is moved after being clamped and hooked tightly, the operation is simple, efficient and low in cost.

[0046] The device is uniformly sprayed with anti-oxidation metal paint, the hook plate 601 in the clamping mechanism 6 is made of stainless steel material, and the remaining components are made of iron. By using 304 stainless steel material to manufacture the hook plate and spraying the entire device with anti-oxidation metal paint, the corrosion resistance and fatigue resistance of the device are significantly improved. Compared with the problem that the steel wire rope and the hook are easily bent and deformed after long-term use in the prior art, the structure of the device is more solid and durable, and the service life of the device can be significantly prolonged.

[0047] The overall working process is as follows: the clamp is very simple to use, the lifting ring is hung and locked on the sling lock hook, when the limiting assembly one 51 and the limiting assembly two 52 are separated, the clamp is in an open state, the clamp is slowly lowered, the hook plate 601 is placed in the middle of the lithium battery module reinforcing rib groove by hand, the clamp is lifted, the two locking plates 603 slowly approach, the plate block of the locking plate 603 extending vertically outward can slowly hook the reinforcing rib plate block extending vertically inward, the two are overlapped and locked to be completely fastened, the lithium battery module can be moved stably by continuing to lift the clamp. After the module is moved, the clamp is slowly lowered, the limiting assembly one 51 slowly rotates downward and clamps the limiting assembly two 52, then the clamp is slowly raised, if the locking plate 603 extends and hooks the reinforcing rib, the clamp can be continued to be raised by manual operation, and the cycle is repeated.

[0048] In order to facilitate the understanding of the above technical scheme of the utility model, the above technical scheme of the utility model is described in detail through specific use mode.

[0049] The specific working process is as follows: first, the lifting ring 1 of the device is hung and buckled on the lifting hook of the gourd lifting machine, and the connection between the lifting machine and the device is ensured to be firm. Then, the operator rotates the limiting component one 51 and the limiting component two 52 to separate them, and ensures that the device as a whole is in an open state. Slowly lower the lifting machine, so that the hook plate 601 in the clamping mechanism 6 is aligned with the reinforcing rib groove of the lithium battery module, and the inner clamping plate block 604 of the hook plate 601 is located near the middle of the reinforcing rib groove. By lifting the pull rod 2, the connecting rod transmission mechanism 4 starts to drive, driving the compression plate 602 and the locking plate 603 in the clamping mechanism 6 to gradually approach the reinforcing rib groove of the lithium battery module. During the lifting process, the inner clamping plate block 604 of the hook plate 601 and the positioning plate block 605 of the compression plate 602 are gradually tightened, tightly clamping the reinforcing rib of the module and hooking the reinforcing rib groove. When the clamping mechanism completely clamps the module, the device forms a stable connection with the module, and the module can be safely moved. The operator continues to lift the lifting machine, slowly lifts the clamped lithium battery module, and ensures that the module does not shake or loosen during movement. According to the needs, the module is moved to the designated position, and the whole movement process is stable and safe.

[0050] When the module reaches the target position, slowly lower the lifting machine, so that the module gradually contacts the ground or the target installation position. Continue to lower the lifting machine, and the connecting rod transmission mechanism 4 reverses the action, and the compression plate 602 and the locking plate 603 in the clamp gradually loosen. The limiting component one 51 is slowly rotated downward and clamped into the limiting groove of the limiting component two 52, locking the connecting rod transmission mechanism, so that the device is tightly locked and kept in a completely open state. Ensure that the hook plate 601 in the clamping mechanism 6 is completely separated from the reinforcing rib of the module, and manually adjust the hook plate 601 or the locking plate 603 to avoid hooking. Slowly lift the lifting machine, move the device away from the module, and restore the initial state, ready for the next operation.

[0051] The device realizes the opening and closing action of the clamp through the mechanical transmission action of the connecting rod transmission mechanism 4. In the clamping state, the positioning plate block 605 of the compression plate 602 and the inner clamping plate block 604 of the hook plate 601 tightly clamp the reinforcing rib of the module, ensuring the stability and safety of the module during lifting. The limiting mechanism 5 prevents the connecting rod transmission mechanism from accidentally loosening through the clamping groove structure of the limiting component one 51 and the limiting component two 52, ensuring the reliability of the whole lifting process.

[0052] The device is designed to be simple to operate, and only one person is needed to complete the grabbing and moving of the module, which significantly improves the operation efficiency and reduces the use cost, and is suitable for the lifting needs of lithium battery modules of various specifications.

[0053] Through the above improvement, the problems of left and right shaking, easy wear of steel wire rope and complex operation in the prior art are effectively solved, and the device has significant advantages in safety, stability, durability and economy, and provides a more reliable solution for efficient lifting of lithium battery modules.
