Description

Technical Field

[0001] This utility model relates to the field of lithium battery PACK production technology, specifically a lifting hook device. Background Technology

[0002] In recent years, with the rapid development of the new energy industry, the number of lithium battery pack packaging vehicles has surged year after year. During the production process of lithium battery packs, the packs need to be transferred between different stages. Currently, the lifting and transfer of battery packs often uses a combination of customized irregular-shaped hooks or lifting bolts, which presents the following problems:

[0003] (1) Traditional hooks are often inserted into the lifting hole from bottom to top, which requires leaving space for the operation of the hook. For different packs, the hook needs to be designed with specific dimensions, which makes it less versatile.

[0004] (2) Traditional hooks lack anti-detachment design, resulting in poor safety; or they use threaded locking to prevent detachment, which is inconvenient to operate and inefficient. Utility Model Content

[0005] The technical problem to be solved by this utility model is how to improve the versatility and safety of the hook.

[0006] This utility model solves the above-mentioned technical problems through the following technical means:

[0007] This utility model provides a hook device, which includes a lifting lug and a guide sleeve. The lifting lug is fixed to the top of the guide sleeve. An anti-detachment component and a stop pin component are respectively provided at both ends of the guide sleeve. The stop pin component includes a telescopic shaft, a stop pin and a spring. The stop pin is fixed in the guide sleeve by the spring and moves up and down in the guide sleeve by the telescopic shaft so that the stop pin can extend and retract into the guide sleeve.

[0008] Beneficial effects: This utility model, by pulling the telescopic shaft upwards, causes the stop pin to retract into the guide sleeve due to the spring force. The guide sleeve is then inserted into the lifting hole of the PACK battery pack from top to bottom. Releasing the telescopic shaft allows it to move downwards, lifting the stop pin so that it extends the guide sleeve out of the lifting hole. The PACK battery pack is then lifted using the lifting lugs. The anti-detachment component confines the guide sleeve within the lifting hole, preventing it from falling out, thus improving the safety and convenience of the lifting process and increasing production efficiency. This utility model's hook device requires no additional operating space or special lifting hole design, making it versatile.

[0009] Preferably, the bottom side of the guide sleeve is provided with a stepped hole, the spring is sleeved on the stop pin and set in the stepped hole, and the stop pin can be extended and retracted into the stepped hole by the up and down movement of the telescopic shaft.

[0010] Preferably, the end of the stop pin inside the stepped hole has a bevel.

[0011] Beneficial effects: By providing an inclined surface at the end of the stop pin, this utility model makes it easier to push the stop pin open when the telescopic shaft moves downward, making it easier for the telescopic shaft to pass through the stop pin and allowing the stop pin to extend out of the stepped hole more quickly.

[0012] Preferably, the lifting lug is fixed to the top of the guide sleeve by a flange.

[0013] Preferably, the telescopic shaft can pass through the flange, and the telescopic shaft has a handle above the flange. The telescopic shaft is positioned inside the guide sleeve via the handle.

[0014] Beneficial effects: The telescopic shaft of this utility model passes through the flange and can move up and down in the flange. The handle prevents the telescopic shaft from falling completely into the guide sleeve. The handle also makes it easier to pull the telescopic shaft up or press it down.

[0015] Preferably, the anti-detachment component includes a guide spring and a limiting ring, both of which are sleeved on the outer side of the guide sleeve, with the guide spring positioned between the flange and the limiting ring.

[0016] Beneficial effect: When the guide sleeve is inserted into the lifting hole of the PACK battery pack from top to bottom, it is compressed by the guide spring through the limiting ring. When the stop pin extends out of the stepped hole at the bottom of the lifting hole, the elastic force of the guide spring fixes the limiting ring to the top of the lifting hole, thereby preventing the lifting hole from detaching from the lifting hook device.

[0017] Preferably, the limiting ring is provided with a pin, which passes through the limiting ring and connects to the telescopic shaft.

[0018] Preferably, the pin can pass through the limiting ring and the telescopic shaft to reach the other side of the limiting ring.

[0019] Preferably, the guide sleeve has an oblong hole, through which a pin passes and connects to the telescopic shaft.

[0020] Beneficial effects: This utility model uses a pin to fix the limiting ring on the telescopic shaft, and the limiting ring moves up and down in the waist-shaped hole at the same time as the telescopic shaft moves up and down.

[0021] Preferably, the hook device is inserted into the lifting hole through a stop pin assembly, and the hook device is fixed in the lifting hole by an anti-detachment assembly. Attached Figure Description

[0028] Example 1

[0029] according to Figure 1 As shown, this embodiment provides a lifting hook device, which includes a lifting lug 10 and a guide sleeve 20. The lifting lug 10 is fixed to the top of the guide sleeve 20 by a flange 11. The function of the lifting lug 10 is to facilitate lifting the lifting hook device. The upper and lower ends of the guide sleeve 20 are provided with anti-detachment components and stop pin components. The guide sleeve 20 is inserted into the lifting hole of the PACK battery pack from top to bottom through the stop pin component. At this time, the anti-detachment component limits the guide sleeve 20 in the lifting hole, thereby preventing the lifting hole from detaching from the lifting hook device.

[0030] The stop pin assembly includes a telescopic shaft 30, a stop pin 31, and a spring 32. The guide sleeve 20 has a stepped hole 21 on its bottom side. The spring 32 is sleeved on the circumference of the stop pin 31 and positioned within the stepped hole 21. At this time, the stop pin 31 is retracted inside the stepped hole 21 due to the elastic force of the spring 32. The end of the stop pin 31 has a bevel 311. The telescopic shaft 30 is positioned inside the guide sleeve 20 and can push open the bevel 311 of the stop pin 31 and pass through the stop pin 31, pushing a portion of the stop pin 31 out of the stepped hole 21. When the stop pin 31 extends out of the stepped hole 21, its outer diameter is larger than the lifting hole, so the PACK battery pack can be lifted using the lifting lug 10. Specifically... Figure 1 As shown.

[0031] The telescopic shaft 30 passes through the flange 11 and has a handle 34 above it. The outer diameter of the flange 11 is larger than the inner diameter of the guide sleeve 20, and it is fixed to the top of the guide sleeve 20. The flange 11 has a through hole (not shown in the figure) in the center to allow the telescopic shaft 30 to pass through. The outer diameter of the handle 34 is larger than the inner diameter of the through hole, so that the handle 34 can be hung on the top of the flange 11 to prevent the telescopic shaft 30 from falling completely into the guide sleeve 20. At the same time, the operator can pull the telescopic shaft 30 upward through the handle 34. At this time, the telescopic shaft 30 is separated from the stop pin 31, and the stop pin 31 is retracted into the stepped hole 21 by the elastic force of the spring 32, as shown in the figure. Figure 4 As shown.

[0032] The anti-detachment component includes a guide spring 40 and a limiting ring 41. Both the guide spring 40 and the limiting ring 41 are sleeved on the outside of the guide sleeve 20. One end of the guide spring 40 is fixedly connected to the flange 11, and the other end is fixedly connected to the limiting ring 41. The guide spring 40 can fix the limiting ring 41 above the stop pin 31. The outer diameter of the limiting ring 41 is larger than the inner diameter of the lifting hole. When the guide sleeve 20 is inserted into the lifting hole, the limiting ring 41 is stuck at the top of the lifting hole, thereby preventing the lifting hole from detaching from the hook device. The guide spring 40 can also reduce the impact of the limiting ring 41 on the flange 11.

[0033] The working principle of the hook device in this embodiment is as follows:

[0034] The operator pulls the telescopic shaft 30 upward using handle 34. This disengages the telescopic shaft 30 from the stop pin 31, causing the stop pin 31 to retract into the stepped hole 21 due to the spring force of spring 32. Then, the guide sleeve 20 is inserted downwards into the lifting hole of the PACK battery pack. The operator then releases handle 34, causing the telescopic shaft 30 to move downwards towards the inclined surface 311 of the stop pin 31. This allows the shaft to push open and pass through the stop pin 31, causing a portion of the stop pin 31 to protrude out of the stepped hole 21. Simultaneously, the insertion of the guide sleeve 20 downwards into the lifting hole of the PACK battery pack compresses the limiting ring 41 and the guide spring 40. When a portion of the stop pin 31 protrudes out of the stepped hole 21, the spring force of the guide spring 40 secures the limiting ring 41 to the top of the lifting hole, preventing the lifting hole from detaching from the hook device. The PACK battery pack is then lifted using the lifting lug 10, enabling its transfer.

[0035] Example 2

[0036] according to Figure 2 As shown, this embodiment provides a hook device. Compared to Embodiment 1, this embodiment differs in that: the guide sleeve 20 has oblong holes 22 on opposite sides, and the limiting ring 41 and the telescopic shaft 30 have through holes (not shown) on opposite sides. The limiting ring 41 has a pin 411, and the through holes are used for the pin 411 to pass through the limiting ring 41, the oblong holes 22, and the telescopic shaft 30 to reach the other side. Specifically, as shown... Figure 4 As shown.

[0037] The purpose of this design is that when the operator pulls the telescopic shaft 30 upward using the handle 34, the telescopic shaft 30 is lifted upward and moves away from the stop pin 31. Simultaneously, the limiting ring 41 also moves upward, making it easier to insert the guide sleeve 20 into the lifting hole of the PACK battery pack from top to bottom. At the same time, when the operator releases the handle 34, the telescopic shaft 30 moves downward, simultaneously causing the limiting ring 41 to move downward as well. This allows the limiting ring 41 to move more quickly to the top of the lifting hole, fixing the lifting hole between the limiting ring 41 and the stop pin 31, thus preventing the lifting hole from detaching from the hook device. The PACK battery pack is then lifted using the lifting lug 10, enabling its transfer. Because the guide sleeve 20 has an oblong hole 22, the distance the telescopic shaft 30 moves up and down due to the pin 411 is equal to the vertical distance of the oblong hole 22.

[0038] The hook device of this utility model adopts a top-down insertion method, which can be directly inserted into the lifting hole of the PACK battery pack without the need for additional operating space or special lifting hole design, realizing the universality of the lifting hole and the compatible use of the hook device. After the hook device is inserted into the lifting hole, the lifting hole is fixed between the limiting ring 41 and the stop pin 31, realizing the anti-detachment connection between the hook device and the lifting hole, which greatly simplifies the operation process, improves the safety and convenience of the lifting process, and improves production efficiency.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
