[0027] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0028] As described in the background section, chute-type battery packs have unique structural features. Currently, conventional hooks cannot be used to lift chute-type battery packs, and even if they are used, there are problems such as slippage or center of gravity shift.

[0029] Therefore, this utility model provides a lifting device and lifting system in its embodiments, which can solve the above problems, and will be described in detail below.

[0030] Please refer to Figures 1 to 3 The lifting device includes a hook 1 and a locking pin assembly 2. The hook 1 has a retaining part 111, which can be engaged in the groove 30 of the battery pack 3. The locking pin assembly 2 includes a locking pin 20 and a limiting member 21. The locking pin 20 is slidably connected to the hook 1 and can abut against the fastening groove 32 of the battery pack 3. The limiting member 21 is disposed on the hook 1 and slidably cooperates with the locking pin 20, limiting the sliding range of the locking pin 20. When it is necessary to lift the grooved battery pack 3, the retaining part 111 of the hook 1 is engaged in the groove 30 of the battery pack 3, and the locking pin 20 is pulled or pushed so that the locking pin 20 abuts against the fastening groove 32 of the battery pack 3, thereby fixing the retaining part 111 on the groove 30 of the battery pack 3, so that the lifting device can be firmly connected to the battery pack 3 for easy lifting. The lifting device of this utility model embodiment is specifically designed for the lifting of the sliding battery pack 3, and can stably and safely lift the sliding battery pack 3. Of course, the lifting device can also be used for the lifting of other objects, and its specific scope of application is not limited.

[0031] refer to Figure 3 The sliding battery pack 3 has a box-shaped shape. The side walls of its outer shell are provided with sliding grooves 30 and fastening grooves 32. The opening of the sliding groove 30 faces downward. Multiple rollers 31 are spaced apart on the groove wall of the sliding groove 30. The fastening groove 32 is located above the sliding groove 30 and parallel to the sliding groove 30. The opening of the fastening groove 32 faces outward.

[0032] Therefore, to adapt to the opening direction and shape of the slide groove 30 and the fastening groove 32, the end of the holding part 111 of the hook 1 in this embodiment is vertically upward, and the width of the holding part 111 matches the distance between the two rollers 31. When the holding part 111 is engaged in the slide groove 30, pulling the holding part 111 upward can drive the battery pack 3 off the ground. Moreover, the two rollers 31 limit the holding part 111, preventing the holding part 111 from sliding. The locking pin 20 can be slidably connected to the hook 1. The horizontal sliding movement of the locking pin 20 allows the end of the locking pin 20 to abut in or disengage from the fastening groove 32. When the end of the locking pin 20 abuts in the fastening groove 32, the holding part 111 can be fixed in the slide groove 30. When the end of the locking pin 20 disengages from the fastening groove 32, the holding part 111 can be removed from the slide groove 30. The groove wall of the slide 30 fixes the holding part 111 in the X-axis direction, the rollers 31 on both sides of the holding part 111 limit and fix it in the Y-axis direction, and the locking pin 20 and the fastening groove 32 abut against each other in the Z-axis direction to limit and fix the holding part 111.

[0033] refer to Figure 4 and Figure 5 In this embodiment, the hook 1 includes an upper hook body 10 and a lower hook body 11, which are rotatably connected to ensure that the upper hook body 10 can rotate freely to adapt to hoisting movement. Specifically, the lower part of the upper hook 10 is provided with a receiving groove 101, and the upper part of the lower hook 11 is provided with a support ear 112. There are two receiving grooves 101 and two support ears 112, and the two support ears 112 are respectively housed in the two receiving grooves 101. The support ears 112 and the groove walls of the receiving grooves 101 are provided with insertion holes 113. The insertion holes 113 are opened along the Y-axis direction, and the insertion holes 113 on the support ears 112 and the insertion holes 113 on the groove walls of the receiving grooves 101 are both through holes. The insertion holes 113 on the support ears 112 match the insertion holes 113 on the groove walls of the receiving grooves 101. By inserting a rotating shaft 12 into the insertion holes 113 on the support ears 112 and the insertion holes 113 on the groove walls of the receiving grooves 101, the upper hook 10 and the lower hook 11 can be rotatably connected together.

[0034] The upper part of the upper hook body 10 is also provided with a lifting hole 102 for connecting with a lifting rope. The lower hook body 11 is provided with a retaining part 111, the end of which is vertically upward. There is a channel between the retaining part 111 and the lower hook body 11, so that the groove wall of the sliding groove 30 of the battery pack 3 can be engaged in the channel. The lower hook body 11 is also provided with two locking holes 114. Both locking holes 114 are horizontally opened along the X-axis and penetrate the front and rear side walls of the lower hook body 11. The locking holes 114 can accommodate part of the locking pin 20. The lower hook body 11 is also provided with a limiting mounting hole. The limiting mounting hole is opened along the Y-axis and extends to the locking hole 114. The limiting mounting hole is used to install a limiting member 21, which limits the sliding range of the locking pin 20.

[0035] refer to Figure 6 and combined Figure 2 The locking pin assembly 2 includes a locking pin 20 and a limiting member 21. The locking pin 20 is U-shaped, with both ends of the U-shape inserted into two locking holes 114. Limiting grooves 201 are formed on the side walls of the U-shape of the locking pin 20, which are formed along the X-axis. The end of the limiting member 21 can be accommodated in the limiting groove 201, thereby preventing the locking pin 20 from sliding out of the locking holes 114. The limiting member 21 can be a screw, and the limiting mounting hole can be a screw hole. The limiting member 21 is threaded into the screw hole. When the screw is turned, the end of the screw can be accommodated in or disengaged from the limiting groove 201, thereby facilitating the removal of the entire locking pin assembly 2 from the lower hook body 11.

[0036] The locking pin assembly 2 also includes an elastic element 22, a first cotter pin 23, and a second cotter pin 24. The first cotter pin 23 is fixed inside the lower hook body 11, and the second cotter pin 24 is fixed inside the locking pin 20. The first cotter pin 23 and the second cotter pin 24 are arranged perpendicular to each other. The elastic element 22 can be a spring, with its two ends connected to the first cotter pin 23 and the second cotter pin 24, respectively. When the locking pin 20 is dragged along the locking hole 114, the spring is stretched. When the locking pin 20 loses the external drag force, the spring's rebound will cause the locking pin 20 to return to its original position. Of course, the lower hook body 11 and the locking pin 20 are both provided with corresponding holes to facilitate the installation of the first cotter pin 23 and the second cotter pin 24.

[0037] To facilitate dragging the locking pin 20, a pull member 25 is provided on the locking pin 20, which can pull the locking pin 20 to slide along the locking hole 114. The pull member 25 can be a pull ring, with its two ends rotatably connected to the upper and lower walls of the locking pin 20, allowing the pull ring to be stacked on the surface of the lower hook body 11. Of course, the pull member 25 can also have other structural forms, which are not limited.

[0038] To reduce the overall weight of the lifting device, weight-reducing holes 13 can be made on the hook 1. For example, weight-reducing holes 13 can be made on the clamping part 111 or on the lower hook body 11 to reduce the weight of the hook 1.

[0039] The lifting device of this utility model embodiment is adapted for lifting a sliding battery pack 3. When using the lifting device of this utility model embodiment to lift the sliding battery pack 3, first drag the pulling member 25 to move the locking pin 20 in the X-axis direction. Align the holding part 111 of the lower hook body 11 with the opening of the sliding groove 30 of the battery pack 3 and push it upward so that the holding part 111 is locked in the sliding groove 30 and its two sides are connected to the rollers 31. Then release the pulling member 25. Under the action of the elastic member 22, the locking pin 20 moves towards the fastening groove 32 of the battery pack 3. The end of the locking pin 20 abuts against the fastening groove 32. The lifting device is connected and fixed to the battery pack 3. The lifting device can be connected to the crane for lifting and moving by fixing the two opposite sides of the battery pack 3. When it is necessary to remove the lifting device from the battery pack 3, drag the pulling member 25 to disengage the end of the locking pin 20 from the fastening groove 32, and then pull the holding part 111 downward so that the holding part 111 is disengaged from the sliding groove 30 of the battery pack 3.

[0040] An embodiment of this utility model also provides a hoisting system, including the above-mentioned hoisting device and a lifting device. A hoisting rope is connected to the lifting device, one end of which is fixed to the lifting arm of the lifting device, and the other end of which passes through the hoisting hole 102 of the upper hook body 10 and is tied tightly. When the lifting arm is lifted upward, the hoisting device is moved by the hoisting rope. The hoisting device is snapped and fixed on the battery pack 3, thereby enabling the hoisting and transfer of the battery pack 3.

[0041] The lifting system includes the aforementioned lifting tools and possesses all the functions of lifting tools.
