[0033] In the embodiment of the present utility model, a guide groove 202 is provided on the aforementioned pull - ring guide 2, and the pull - ring 3 is arranged in the guide groove 202. The outer contour of the pull - ring 3 is adapted to the inner contour of the guide groove 202. And the pull - ring 3 slides up and down in the guide groove 202.

[0034] In order to enable the pull ring 3 to operate smoothly in the guide groove 202, in the embodiment of the present utility model, the longitudinal depth of the opened guide groove 202 is greater than the length of the pull ring 3, and the transverse width of the guide groove 202 is adapted to the width of the pull ring 3. The longitudinal depth of the guide groove 202 being greater than the length of the pull ring 3 is to ensure that the pull ring 3 can move up and down. The transverse width of the guide groove 202 being adapted to the width of the pull ring 3 is to ensure that the pull ring 3 does not shift in position during the up and down movement. The longitudinal depth and the transverse width of the above-mentioned guide groove 202 can be reasonably adjusted according to the actual situation, as long as it can ensure that the pull ring 3 stably performs the up and down sliding operation in the above-mentioned guide groove 202.

[0035] In addition, in order to further ensure the stability of the pull ring 3 during the up and down operation, in the embodiment of the present utility model, a number of guide strips 203 are arranged on the outer periphery of the pull ring guide 2, and one side of the guide strip 203 protrudes from the guide groove 202, so as to perform a limiting operation on the pull ring 3, preventing the pull ring 3 from falling outside the pull ring guide 2 due to uneven force during the movement process or the process of hoisting the battery cell, and avoiding safety accidents. The number of the guide strips 203 can be reasonably arranged according to needs, and the arranged position can also be adjusted according to the actual situation.

[0036] In the embodiment of the present utility model, a suspension rod 4 is connected to the aforementioned pull ring 3. More specifically, the suspension rod 4 is passed through the inside of the lower end of the pull ring 3 and synchronously passed through the inside of the lower end of the pull ring guide 2. The suspension rod 4 includes a convex portion 401 and a thin rod portion 402, and the aforementioned steel ball 5 cooperates with the convex portion 401 or the thin rod portion 402 to realize the function of limiting or releasing the limit of the battery cell. The number of the steel balls 5 can be reasonably arranged according to needs.

[0037] In addition, in the embodiment of the present utility model, a sleeve 6 is sleeved outside the aforementioned suspension rod 4. One end of the sleeve 6 abuts against the lower end surface of the aforementioned pull ring guide 2, and the other end is provided with a number of steel ball through holes 7 for the aforementioned steel balls 5 to expose / retreat. The diameter size of the steel ball through holes 7 is adapted to the steel balls 5, and the number of the arranged steel ball through holes 7 also corresponds to the number of the steel balls 5 one by one.

[0038] In the embodiment of the present new model, by means of the above-mentioned pull ring 3 providing a corresponding downward pressure on the suspension rod 4, the aforementioned convex portion 401 pushes the steel ball 5 out of the steel ball through hole 7 opened on the aforementioned sleeve 6, and the steel ball 5 exposes the steel ball through hole 7, so as to limit the steel ball 5 on the lower end surface of the hoisting connecting plate 9 of the battery cell module 8, thereby providing a corresponding hanging and limiting effect for the battery cell module 8.

[0039] The lower end of the above-mentioned suspension rod 4 protrudes from the aforementioned sleeve 6 to form a protruding section. In the embodiment of the present invention, when the battery cell lifting device transfers the battery cell module 8 to the target rack position and needs to remove the lifting device, the cross beam at the target rack position will support against the lower end of the aforementioned protruding section, thereby pushing the suspension rod 4 upward, causing the aforementioned convex portion 401 to rise. At this time, the steel ball is located at the aforementioned thin rod portion 402, and the steel ball 5 disengages and retracts from the steel ball through hole 7 to unlock, thereby completing the release of the lifting device and realizing the release of the limit on the battery cell.

[0040] During specific use, insert the end of the suspension rod of the battery cell lifting device into the lifting hole 10 of the lifting connection plate 9, and simultaneously press down the pull ring 3 to push out and limit the steel ball 5 to the lower end surface of the lifting installation plate 9. Then, with the help of a hook or a rope cooperating with the lifting ring 1, lift the battery cell module 8 to transfer it to the target rack. When the lifting device is to be released, use the cross beam on the target rack to provide an upward thrust to the lower end of the aforementioned suspension rod 4, thereby retracting and unlocking the steel ball 5 from the lower end surface of the lifting installation plate 9, and the pull ring 3 also resets accordingly to complete the release of the lifting device.

[0041] In summary, for the battery cell lifting device disclosed in the present invention, by arranging steel balls on the battery cell lifting device, the expansion and contraction of the steel balls are used to provide a hanging force for the battery cell; at the same time, with the help of the pull ring and the suspension rod, in cooperation with the convex portion on the suspension rod, the expansion and contraction operation of the steel balls is realized; in addition, a pull ring guide is provided to provide corresponding limiting and guiding effects for the pull ring to ensure the stability of the pull ring during operation. A sleeve is sleeved outside the suspension rod, and a steel ball through hole cooperating with the aforementioned steel ball is opened on the sleeve. The lower end of the suspension rod protrudes from the sleeve, so that when the lifting device reaches the cross beam of the rack, it is convenient for the cross beam to abut against the lower end of the suspension rod to push the suspension rod upward, thereby unlocking the steel ball from the steel ball through hole and causing the lifting device to be released.
