Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, and mainly to a battery PACK housing lifting device. Background Technology

[0002] With the large-scale development of electric vehicles and energy storage systems, the size, weight and structural complexity of battery pack casings have increased significantly. For example, Tesla's 4680 battery module weighs over 200kg, while CATL's Kirin battery, after adopting CTP technology, has a higher casing integration. During hoisting, both lightweight and high-precision positioning must be taken into account. Not only can traditional manual or semi-automatic hoisting tools not meet the production line pace, thus reducing production efficiency, but traditional hoisting tools also have poor versatility and cannot use casings of various specifications.

[0003] Utility model application CN202421502148.0 relates to a battery lifting device. The battery lifting device consists of a lifting frame, lifting components, multiple lifting straps, and multiple locking components. The lifting components, with the aid of external force, pull the lifting frame up. The lifting straps are mounted on the frame of the lifting frame, and the locking components are located at the free ends of the straps. When the lifting frame is pulled up, the battery is lifted by the straps and locking components. The locking components include a connecting part and a stop part. The stop part is located at the end of the connecting part and can be inserted into the battery casing through a lifting hole in the battery casing. With this setup, during hoisting, the stop part only needs to be inserted through the hoisting hole. After the hoisting frame is lifted, the stop part can automatically position itself in the locking position, which also prevents the locking parts from falling off during hoisting. Once the hoisting is completed, the locking parts will naturally leave the locking position, and the battery hoisting device can be disassembled simply by removing the stop part from the hoisting hole, achieving the effect of saving time and effort in the hoisting process.

[0004] However, the existing technology still has shortcomings: 1. It is highly dependent on manual operation, requiring manual adjustment of the clamp position one by one, which is time-consuming and prone to errors, resulting in low efficiency. 2. The clamps of the existing lifting devices rely on pins to fix the hooks, which poses a risk of human negligence in locking them, increasing safety hazards. 3. The gripping equipment has a low range of versatility and is limited to a single type of shell that it can grip.

[0005] Therefore, there is an urgent need for a battery pack housing lifting tool that is easy to grasp, requires less human intervention, is widely applicable, and has high safety. Utility Model Content

[0006] To address the above issues, a battery pack housing lifting device was developed that offers convenient gripping with reduced manual intervention, wide versatility, and high safety. Through the adjustable-spacing suction mechanism and the combination of the suction nozzle structure with the operating table, the device's versatility is effectively improved, and its operation is simplified. This not only reduces safety risks and manual intervention but also ensures high stability.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A battery pack housing lifting device, comprising:

[0009] The main body of the hoisting frame;

[0010] The main body of the hoisting frame includes an operating platform, a support frame, and a suction mechanism;

[0011] The operating platform is fixed to one side of the top of the main body of the hoisting frame, the support frame is connected to the bottom of the operating platform, and the suction mechanism is connected to the bottom of the support frame; the suction mechanism includes at least two sets of suction components, which adsorb the shell through the suction components, and the spacing between the suction components can be adjusted.

[0012] As an improvement, the adsorption assembly includes a straight rod and two sets of adsorption nozzles. The straight rod has a square hole, and the two sets of adsorption nozzles are respectively sleeved on both sides of the straight rod through a sliding tube. The sliding tube is provided with a positioning element for fixing the position of the adsorption nozzles.

[0013] As an improvement, the suction nozzle is provided in two types: a waist-shaped suction nozzle and a round suction nozzle.

[0014] As an improvement, the suction mechanism further includes a transverse track, and the square hole is fitted onto the transverse track and fixed in position by a tensioning element.

[0015] As an improvement, the support frame is a frame structure consisting of two parallel vertical beams and a reinforcing horizontal beam connecting the two vertical beams. The bottom of the two parallel vertical beams is fixedly connected to the horizontal track, and the top of the horizontal beam is fixedly connected to the operating table through a connecting rod.

[0016] As an improvement, the top of the support frame is also provided with a lifting eye screw, the installation position of which coincides with the central axis of the support frame.

[0017] As an improvement, the control panel includes a handrail and an operating component, wherein the handrail is square in shape.

[0018] The beneficial effects of this utility model are as follows:

[0019] (1) In this utility model, the adsorption component of the adsorption mechanism can adjust the spacing through the horizontal track, and its adsorption nozzle can slide along the straight rod to adjust the longitudinal position. With the combination of waist-shaped and round adsorption nozzles, it can flexibly adapt to battery PACK shells of different sizes and different surface adsorption requirements. There is no need to customize special hangers for a single specification shell, which greatly improves the equipment reuse rate.

[0020] (2) In this utility model, the adsorption component and the adsorption nozzle are fixed only by the tightening and positioning parts. The adjustment process does not require complicated tools. When adapting to the new specification shell, only the adjustment steps need to be repeated. The operation threshold is low and the application range is wide, effectively reducing manual intervention.

[0021] (3) In this utility model, the lifting eye screw coincides with the central axis of the support frame, ensuring that the lifting point is aligned with the center of the shell during hoisting, and the force is even and does not tilt. The operator can adjust the posture of the lifting device in real time through the handrail, and cooperate with the lifting equipment to avoid the shell shaking or colliding during the transfer process.

[0022] (4) The square handrail in this utility model fits the gripping habit, the anti-slip treatment improves the stability of operation, and the control panel integrates control functions, so that the operator can complete the core operation without frequently moving the position, thus reducing the workload.

[0023] (5) The integrated frame composed of the vertical beam and the reinforcing horizontal beam in the support frame of this utility model effectively disperses the lifting load, avoids deformation of the lifting equipment when bearing load, and ensures the structural stability of long-term use.

[0024] In summary, this utility model provides a battery pack housing lifting tool that is convenient to grasp, reduces manual intervention, is widely applicable, and has high safety. It improves production efficiency, reduces safety risks, and meets the requirements for multiple housing specifications. Attached Figure Description

[0034] Example 1:

[0035] like Figures 1 to 5 As shown, a battery pack housing lifting device includes:

[0036] 1. Main body of the hoisting frame;

[0037] The main body 1 of the hoisting frame includes an operating platform 2, a support frame 3, and a suction mechanism 4;

[0038] The operating platform 2 is fixed to one side of the top of the hoisting frame body 1, the support frame 3 is connected to the bottom of the operating platform 2, and the suction mechanism 4 is connected to the bottom of the support frame 3; the suction mechanism 4 includes at least two sets of suction components 41, which adsorb the housing 10 through the suction components 41, and the spacing between the suction components 41 can be adjusted.

[0039] The adsorption assembly 41 includes a straight rod 411 and two sets of adsorption nozzles 412. The straight rod 411 is provided with a square hole 413. The two sets of adsorption nozzles 412 are respectively sleeved on both sides of the straight rod 411 through a sliding tube 414. The sliding tube 414 is provided with a positioning member 415 for fixing the position of the adsorption nozzles 412.

[0040] There are two types of suction nozzles 412: waist-shaped suction nozzle 4121 and round suction nozzle 4122.

[0041] It should be noted that both types of suction nozzles have built-in one-way valves. When one suction nozzle leaks air, the other suction nozzles can still maintain suction force, thus improving the safety of hoisting.

[0042] The suction mechanism 4 also includes a transverse track 42, and the square hole 413 is fitted onto the transverse track 42 and fixed in position by a fastener 43.

[0043] It should be noted that the square hole 413 is located at the center of the straight rod 411, and its hole wall is adapted to the transverse track 42 to ensure sliding accuracy while avoiding jamming.

[0044] The support frame 3 is a frame structure consisting of two parallel vertical beams 31 and a reinforcing horizontal beam 32 connecting the two vertical beams 31. The bottom of the two parallel vertical beams 31 is fixedly connected to the horizontal rail 42, and the top of the horizontal beam 32 is fixedly connected to the operating table 2 through a connecting rod 33.

[0045] The top of the support frame 3 is also provided with a lifting eye screw 34, and the installation position of the lifting eye screw 34 coincides with the central axis of the support frame 3.

[0046] It should be noted that during installation, the eye bolt 34 engages with the pre-set threaded hole on the top of the support frame via its thread, and the centerline of the eye bolt 34 coincides with the centerline of the support frame 3, ensuring uniform force during lifting and preventing the shell from tilting.

[0047] Secondly, it should be noted that the positioning component 415 is a knob plunger, which cooperates with the positioning hole on the surface of the straight rod 411 to achieve the longitudinal positioning of the suction nozzle 412, ensuring that the suction nozzle 412 does not shift during hoisting. The tensioning component 43 is a butterfly-shaped spiral component, which can be adjusted without tools. The suction component 41 can be fixed and moved by manually rotating the butterfly-shaped spiral component.

[0048] Finally, it should be noted that the suction nozzle 412 adopts a structure of metal base and elastic suction lip, the elastic suction lip being made of nitrile rubber. The suction nozzle 412 and the slide tube 414 are connected by threads, making it easy to disassemble and replace. However, the lateral spacing adjustment is achieved by sliding the straight rod 411 along the lateral track 42, and the longitudinal position adjustment is achieved by sliding the slide tube 414 along the straight rod 411.

[0049] The operating console 2 includes a handrail 21 and an operating component 22, wherein the handrail 21 is square in shape.

[0050] It should be noted that the surface of the handrail 21 is treated with sandblasting and oxidation, which makes it non-slip and comfortable to the touch. The four corners of the handrail are rounded to avoid bumps and scratches during operation. The operating component 22 is used to control the adsorption operation.

[0051] Working principle: Based on the size of the battery pack housing 10 to be hoisted and the surface adsorption requirements, first adjust the lateral spacing of the adsorption assembly 41, loosen the tensioning piece 43, push the straight rod 411 to slide along the lateral track 42 to the appropriate position, then tighten the tensioning piece 4 to fix the straight rod 411. Next, adjust the longitudinal position of the adsorption nozzle 412, loosen the positioning piece 415, move the slide tube 414 to slide along the straight rod 411, so that the adsorption nozzle 412 is aligned with the optimal adsorption point of the housing 10, then tighten the positioning piece 415 to lock the adsorption nozzle 412. Then, connect the lifting device to the external lifting equipment through the eye bolt 34, and the operator holds the square handle 21 of the operating platform 2 to control the operation. The overall posture of the lifting device is such that the suction nozzle 412 fits against the surface of the housing 10. The suction system is activated by operating the control unit 22 on the control panel 2. The suction nozzle 412 generates negative pressure and tightly holds the housing 10. Since the installation position of the lifting eye screw 34 coincides with the central axis of the support frame 3, the center of the housing 10 is aligned with the lifting point, ensuring that it is stable and tilt-free after suction. Then, the lifting device is lifted upward by external lifting equipment through the lifting eye screw 34. The frame structure composed of the vertical beam 31 and the reinforcing horizontal beam 32 of the support frame 3 bears the lifting load and ensures the overall rigidity of the lifting device. The operator uses the handrail 21 to assist in adjusting the horizontal position of the lifting device and cooperates with the lifting equipment to complete the lateral movement of the housing 10. The longitudinal movement prevents the housing 10 from shaking or colliding during the transfer. After the housing 10 is transferred to the target position, the operator closes the adsorption system through the operating component 22. The negative pressure of the adsorption nozzle 412 disappears, releasing the adsorption on the housing 10. Then, the lifting equipment is controlled to lift the lifting device, so that the adsorption nozzle 412 is detached from the housing 10, completing one lifting operation. If different specifications of housing 10 need to be lifted, the steps can be repeated.

[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
