Description

Technical Field

[0001] The invention relates to the technical field of lithium battery module grabbing, and in particular to a non-powered lithium battery module grabbing device. Background Art

[0002] With the widespread application of lithium battery modules in new energy vehicles, power storage and other fields, efficient and safe lifting and movement have become a key technology. Most of the existing lithium battery module grabbing devices use mechanical structures to achieve lifting and fixation, but they generally have problems such as poor stability and cumbersome operation.

[0003] For example, the prior art CN217732423U discloses a power battery hoist, including a hoist frame, a hanging plate, a steel wire rope and a hook. The hoist frame is a rectangle that matches the battery box, and the hanging plate is located in the middle above the hoist frame and is connected to the crane through a connecting hole. The head ends of the four steel wire ropes are fixed to the hoist frame near the four corners, and the tail ends are fixed by hooks and are located in the same horizontal plane. The hook is connected to the limit block through a rotating shaft, and the limit block is elliptical to adapt to the hanging hole of the battery box. Although the device is simple to operate, improves the lifting efficiency, and has good stability and connection firmness, it still has the following defects and shortcomings when used: During the hoisting process, the hook and wire rope of the prior art are prone to swaying left and right due to the heavy weight and uneven distribution of the lithium battery module, resulting in an unstable hoisting process and a safety hazard.

[0004] After a long period of lifting heavy objects, the wire rope and hook of the existing lifting equipment may bend or deform due to excessive force, resulting in a gradual increase in the bending diameter of the hook, and even the battery module may be unhooked, increasing the risk of the module falling. During the lifting process, if the module falls, it may damage the product, and cause a fire or explosion due to the collision of the battery cells, posing a threat to personal safety.

[0005] In addition, when using this type of lifting equipment, four hooks need to be hung in the holes of the lithium battery module reinforcement ribs respectively, and the wire rope needs to be kept in a reasonably tensioned state. This usually requires the cooperation of two operators, which has low efficiency and high operating costs. Summary of the invention

[0006] The problem to be solved by the present invention is that the prior art lacks effective limiting and locking, and the lithium battery module may sway left and right during hoisting, the wire rope and the hook may easily wear and deform or even become unhooked after long-term use, and the operation may be complicated and inefficient. A non-powered lithium battery module grabbing device is proposed. By adopting the principle of non-powered mechanical transmission, a connecting rod transmission mechanism, a clamping mechanism and a multi-layer limiting mechanism are designed to improve the stability and safety of the hoisting process, simplify the operating steps, and improve work efficiency, which is suitable for the hoisting needs of various lithium battery modules.

[0007] In order to solve the above problems, the present invention provides a non-powered lithium battery module grabbing device, comprising: Lifting ring, used to connect the crane hook; A pull rod is vertically arranged below the lifting ring, and a connecting hole is provided on the pull rod; A connecting rod transmission mechanism, comprising at least two mutually connected movable connecting rods, one end of the connecting rod transmission mechanism is movably connected to the pull rod, and the other end can realize opening and closing operation through transmission action to drive the clamping or releasing action of the clamp; A limiting mechanism is arranged on the connecting rod transmission mechanism, and comprises a limiting component 1 for locking, wherein the limiting component 1 is a prism structure and can be rotated and inserted into a limiting groove of the limiting component 2 at its lower end, thereby limiting the movement of the connecting rod transmission mechanism; The clamping mechanism, the connecting rod transmission mechanism and the clamping mechanism are fixedly connected through a movable locking piece. When the device is in the open state, the clamping mechanism can be placed in the reinforcement rib groove of the lithium battery module. By lifting the pull rod, the clamping mechanism gradually clamps the reinforcement rib to achieve stable movement of the lithium battery module.

[0008] Preferably, the connecting rod transmission mechanism includes a plurality of first connecting rods and second connecting rods, the first connecting rods are respectively provided with a fixing hole and an inclined hole at both ends, the second connecting rods are provided with holes at both ends and the corners, and the second connecting rods are connected to the first connecting rods through a movable locking member and can move relatively.

[0009] Preferably, the limiting mechanism also includes limiting component three and limiting component four, wherein limiting component three is sleeved on the outer end of limiting component one, and limiting component one is fixed to limiting component three by passing through the threaded grooves opened on limiting component three and limiting component one in sequence through limiting component four.

[0010] Preferably, the limiting component one includes a screw and a fixed block for locking, a positioning screw groove is opened at the side end of the fixed block, the limiting component four is screwed into the positioning screw groove, and the head of the screw is a prism structure, which is rotated and inserted into the limiting groove of the limiting component two.

[0011] Preferably, the second limiting component is in a U-shaped slot structure, and a limiting slot is provided at the center of the second limiting component.

[0012] Preferably, the limiting component three is a cylindrical hollow structure.

[0013] Preferably, the clamping mechanism comprises at least two clamping assemblies arranged opposite to each other, and the clamping assemblies comprise: A hook plate, disposed at the lower end of the clamping assembly, for hooking the reinforcing ribs of the lithium battery module; The clamping plate extends vertically and is arranged on the clamping assembly, and is used to clamp the reinforcing ribs of the lithium battery module to prevent the module from moving during movement.

[0014] Preferably, the clamping mechanism further comprises a locking plate, the pressing plate and the locking plate are arranged to overlap each other, and the hook plate is perpendicular to the pressing plate and the locking plate and extends outwards.

[0015] Preferably, an inner clamping plate perpendicular to the hook plate is provided at the lower end of the hook plate, and the inner clamping plate is used to hook the reinforcing ribs of the lithium battery module.

[0016] As a preferred embodiment, the clamping plate and the locking plate are both caliper-shaped structures, and a positioning plate perpendicular to the clamping plate is provided at the lower end of the clamping plate, and the positioning plate clamps the reinforcing ribs of the lithium battery module. By completely inserting the inner card plates of the hook plates on both sides into the module reinforcing rib grooves, and then lifting the clamp, the positioning plate of the clamping plate will slowly tighten, and the inner card plates and the positioning plates firmly clamp the module reinforcing ribs and hook the reinforcing rib grooves, effectively preventing the module from shaking and unhooking, which threatens personal safety and damages the product. After the battery module has been moved to the designated location, the device continues to move downward and slowly opens, and a limit component 1 in the connecting rod transmission mechanism will rotate downward and be inserted into the limit groove of the lower limit component 2, so that the connecting rod can be locked to fix the entire device. When using such a clamp, only one person is required to operate, and the inner card plate is placed in the reinforcing rib groove, and the clamp can be lifted, and the module can be moved after clamping and hooking. The operation is simple, efficient and low in cost.

[0017] Preferably, the device is evenly sprayed with anti-oxidation metal paint on the whole, the hook plate in the clamping mechanism is made of stainless steel, and the other components are made of iron. By using 304 stainless steel to make the hook plate and spraying the device with anti-oxidation metal paint on the whole, the corrosion resistance and fatigue resistance of the device are significantly improved. Compared with the problem of the wire rope and hook being easy to bend and deform after long-term use in the prior art, the structure of the present invention is more solid and durable, which can significantly extend the service life of the device.

[0018] Compared with the prior art, the present invention has the following beneficial technical effects: The present invention can realize the automatic clamping action of the clamp through the connecting rod transmission mechanism and the clamping mechanism, so that the clamping assembly can firmly clamp the reinforcing ribs of the lithium battery module, thereby improving the stability of the lifting process. Compared with the method of using wire ropes and hooks in the prior art, the instability caused by shaking of the module during the lifting process is effectively avoided, and the stability and safety of the lifting process are greatly improved.

[0019] The present invention adopts a multi-layer limiting mechanism to eliminate the risk of battery modules falling. In particular, the slot structure design of limiting component one and limiting component two can prevent the clamp from accidentally loosening during the lifting process, ensuring that the clamp is always in a locked state when carrying the module, thereby avoiding the risk of the module falling due to loose clamps and reducing the possibility of product damage and battery cell collision.

[0020] The clamp design of the present invention enables it to be used by only one person to complete the grasping and moving of the lithium battery module. Through the transmission action of the connecting rod transmission mechanism, the clamp can automatically complete the opening and closing operation, without the need to rely on manual hooking, adjusting the tension of the wire rope and other complicated steps in the prior art, which effectively reduces the difficulty of operation and improves the work efficiency.

[0021] The mechanical transmission mechanism of the connecting rod transmission mechanism and the clamping mechanism adopted by the present invention replaces the complex power system, which reduces the manufacturing and use costs of the device while maintaining the high efficiency of operation. In addition, the simplicity of operation of the device reduces the labor input, thereby further reducing the comprehensive use cost.

[0022] The present invention fully considers the potential safety hazards during operation, and prevents the module from shaking or loosening during the hoisting process through the limit mechanism, clamping assembly and clamping design. In addition, the device has a solid structure and good anti-fatigue performance, which can effectively prevent safety accidents caused by equipment failure and ensure the personal safety of operators.

[0023] The clamp of the present invention can adapt to reinforcing rib grooves of lithium battery modules of different specifications, and through the flexible adjustment of the connecting rod transmission mechanism, it is suitable for hoisting requirements in a variety of different scenarios, and has good versatility and practicality.

DETAILED DESCRIPTION

[0032] The present invention will be further explained below in conjunction with the accompanying drawings and embodiments.

[0033] Reference Figure 1-Figure 5 As shown, a non-powered lithium battery module grabbing device includes a lifting ring 1, which is a standard circular ring for hanging on a crane hook. The lifting ring 1 is vertically welded to a pull rod 2. The pull rod 2 is a cylinder with a circular hole at the bottom and extends outward. The movable locking parts 3 such as nuts are inserted into the bolts to fix the connecting rods. The connecting rod transmission mechanism 4 has a total of eight connecting rods, which are four elliptical first connecting rods 401 and four dart-shaped second connecting rods 402. A fixing hole 403 is opened on each side of the first connecting rod 401, and two oblique small holes are opened on one side as oblique holes 404. A hole 405 is opened at each end of the second connecting rod 402, and there is also a hole at the corner. The first connecting rods 401 are arranged in groups of two, and are overlapped and fixed on both sides of the circular hole of the pull rod 2. The four second connecting rods 402 are strung together in pairs at the holes at the other ends of the two pairs of first connecting rods 401 and connected with movable locking members 3. The holes of the second connecting rods 402 that are farther from the turning holes are used, and the first connecting rods 401 and the second connecting rods 402 are movable.

[0034] Reference Figure 5-Figure 7 As shown, the two oblique holes on the first connecting rod 401 are used to fix the limiting component 1 51 of the limiting mechanism 5, and the limiting component 2 52 is provided directly below the limiting component 1 51. The limiting component 3 53 is sleeved on the outer end of the limiting component 1 51, and the limiting component 4 54 passes through the thread grooves provided on the limiting component 3 53 and the limiting component 1 51 in sequence to fix the limiting component 1 51 and the limiting component 3 53. The limiting component 2 52 is a U-shaped slot structure, and a limiting slot 521 is provided at the center of the limiting component 2 52. The limiting component 3 53 is a cylindrical hollow structure.

[0035] The limiting component 1 51 is a combination of a screw 510 and a fixed block 511. The side end of the fixed block 511 is provided with a positioning screw groove 512. The limiting component 4 54 is screwed into the positioning screw groove 512. The head of the screw 510 is a prism structure, which is inserted into the limiting groove of the limiting component 2 52 by rotation. The turning part of the second connecting rod 402 is locked with the movable locking member 3 by overlapping and inserting two connecting rods, and the connecting rods are movable. The clamping plate 602 and the locking plate 603 of the clamping assembly 60 of the clamping mechanism 6 are locked below the second connecting rod 402 on both sides. The clamping plate 602 and the locking plate 603 overlap and the clamping plate 602 is placed on the outside. The hook plate 601 is perpendicular to the clamping plate 602, and the locking plate 603 is locked. There is an inner card plate 604 perpendicular to the hook plate 601 below and outward, which is used to hook and clamp the reinforcing ribs of the lithium battery module. The clamping plate 602 and the locking plate 603 are both caliper-shaped structures. There is a downward extension at the lower middle of the clamping plate 602. A positioning plate 605 perpendicular to the clamping plate 602 is provided at the extension to firmly press the reinforcing ribs, which can effectively prevent the module from moving.

[0036] By completely inserting the inner card plate 604 of the hook plates 601 on both sides into the module reinforcement groove, and then lifting the clamp, the positioning plate 605 of the clamping plate 602 will slowly tighten, and the inner card plate 604 and the positioning plate 605 will firmly clamp the module reinforcement and hook the reinforcement groove, effectively preventing the module from shaking and unhooking, which will threaten personal safety and damage the product. After the battery module has been moved to the designated location, the device continues to move downward and slowly opens. A limit component 1 51 in the connecting rod transmission mechanism will rotate downward and be inserted into the limit groove of the lower limit component 2 52, so that the connecting rod can be locked to fix the entire device. When using such a clamp, only one person is required to operate. Put the inner card plate 604 into the reinforcement groove, and then lift the clamp. After clamping and hooking, move the module. The operation is simple, efficient and low cost.

[0037] The whole device is uniformly sprayed with anti-oxidation metal paint. The hook plate 601 in the clamping mechanism 6 is made of stainless steel, and the other components are made of iron. By using 304 stainless steel to make the hook plate and spraying the whole device with anti-oxidation metal paint, the corrosion resistance and fatigue resistance of the device are significantly improved. Compared with the problem of the wire rope and the hook being easily bent and deformed after long-term use in the prior art, the structure of the present invention is more solid and durable, which can significantly extend the service life of the device.

[0038] The overall operation is roughly like this: the clamp is very easy to use, the hanging ring is locked on the hoist hook, when the limit component 1 51 is separated from the limit component 2 52, and the clamp is in the open state, slowly lower the clamp, manually place the hook plate 601 near the middle of the reinforcing rib groove of the lithium battery module, lift the clamp, and the two locking plates 603 slowly approach each other. The plate extending vertically outward of the locking plate 603 can slowly hook the reinforcing rib plate extending vertically inward, and the two overlap and hook and lock until they are completely tightened, and then continue to lift the clamp, and the lithium battery module can be moved stably. After moving the module, slowly lower it, and continue to lower it after the module stops. The limit component 1 51 rotates slowly downward to clamp the limit component 2 52. At this time, the clamp is locked and fixed as a whole to keep the clamp in the open state, and then slowly rises. At this time, if the extension of the locking plate 603 is hooked with the reinforcing rib, it can continue to rise by manually turning it, and this cycle can be repeated.

[0039] In order to facilitate understanding of the above technical solutions of the present invention, the above technical solutions of the present invention are described in detail below through specific usage methods.

[0040] The specific working process is as follows: First, the lifting ring 1 of the device is locked on the hook of the hoist to ensure that the crane is firmly connected to the device. Then, the operator rotates the limit assembly 1 51 and the limit assembly 2 52 to separate them and ensure that the device is in an open state as a whole. Slowly lower the crane so that the hook plate 601 in the clamping mechanism 6 is aligned with the reinforcing rib groove of the lithium battery module, and ensure that the inner clamping plate 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 transmit, driving the clamping 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 604 of the hook plate 601 and the positioning plate 605 of the clamping plate 602 are gradually tightened, firmly 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 moved safely. The operator continues to lift the crane and slowly lifts the clamped lithium battery module to ensure that the module does not shake or loosen during the movement. Move the module to the specified position as needed to ensure that the entire movement process is smooth and safe.

[0041] When the module reaches the target position, slowly lower the crane so that the module gradually contacts the ground or the target installation position. Continue to lower the crane, the connecting rod transmission mechanism 4 reverses, and the clamping plate 602 and the locking plate 603 in the clamp gradually loosen. The limit component 1 51 slowly rotates downward and snaps into the limit groove of the limit component 2 52, locking the connecting rod transmission mechanism so that the device is locked and fixed and keeps the device in a fully open state. Make sure that the hook plate 601 in the clamping mechanism 6 is completely disengaged from the reinforcement ribs of the module, and manually adjust the hook plate 601 or the locking plate 603 to avoid hooking. Slowly lift the crane, move the device away from the module, restore it to the initial state, and prepare for the next operation.

[0042] The device realizes the opening and closing action of the clamp through the mechanical transmission of the connecting rod transmission mechanism 4. In the clamped state, the positioning plate 605 of the clamping plate 602 and the inner clamping plate 604 of the hook plate 601 firmly clamp the reinforcement ribs of the module to ensure the stability and safety of the module during the hoisting process. The limiting mechanism 5 prevents the connecting rod transmission mechanism from accidentally loosening through the card groove structure of the limiting component 1 51 and the limiting component 2 52, thereby ensuring the reliability of the entire hoisting process.

[0043] The device is designed to be easy to operate, and only one person is needed to complete the grabbing and moving of the module, which significantly improves the work efficiency and reduces the cost of use. It is suitable for the lifting needs of lithium battery modules of various specifications.

[0044] Through the above improvements, the present invention effectively solves the problems existing in the prior art such as left and right swaying, easy wear of wire rope, and complicated operation. It has significant advantages in safety, stability, durability and economy, and provides a more reliable solution for the efficient lifting of lithium battery modules.
