[0035] Specifically, when it is necessary to adjust the distance of the movable seat 14, the operator rotates the bolt 204 by turning the handle 205. Since the bolt 204 is threadedly connected to the movable seat 14, when the bolt 204 rotates, it will cause the movable seat 14 to slide in the reserved groove 202. When the movable seat 14 slides, the limiting blocks 201 on the left and right sides of its outer wall will slide in the limiting groove 203. The cooperation between the limiting blocks 201 and the limiting groove 203 can restrict the rotation of the movable seat 14, so that it can only move in a straight line along the direction of the reserved groove 202, thereby achieving precise adjustment of the position of the movable seat 14, and thus changing the distribution of the hook 16 to adapt to the hoisting requirements of lithium battery boxes 3 of different sizes and shapes.

[0036] Reference Figure 1 , Figure 3 and Figure 5 The battery box 3 has mounting feet 21 fixedly connected to the bottom of the outer wall around the perimeter to support and fix the battery box 3. The bottom of each mounting foot 21 has a reserved hole 22 to facilitate fixing the battery box 3 in a specific position. The bottom of the crane 1 has feet 23 fixedly connected to the perimeter to stabilize the crane 1. The bottom of each foot 23 has bolts 24 threadedly connected to the outer wall of the foot 23 to enhance the connection stability between the foot 23 and the ground.

[0037] Specifically, the mounting feet 21 around the outer wall of the battery box 3 and the reserved holes 22 at the bottom can be used to fix the battery box 3 in a specific position to ensure its stability and safety when not being hoisted. The feet 23 are used to increase the contact area between the crane 1 and the ground, distribute the weight of the crane 1 and the pressure generated during hoisting, and improve the stability of the crane 1 when it is working.

[0038] Reference Figure 1 , Figure 2 and Figure 3 A fixing ring 25 is fixedly connected to the middle of the outer wall of the crane 1 for installing and fixing related components. A controller 26 is fixedly connected to the front side of the outer wall of the fixing ring 25 for the operator to control the operation of the crane 1. A heating port 27 is opened on the right side of the outer wall of the battery box 3, which can provide heating function for the inside of the battery box 3 when needed. A communication port 28 is opened at the rear right end of the outer wall of the battery box 3 for realizing communication connection between the battery box 3 and external devices.

[0039] Specifically, the fixed ring 25 in the middle of the outer wall of the crane 1 is used to install and fix the controller 26, which is in a position convenient for the operator to operate and observe, and the controller 26 is used to control the actions of the crane 1 to realize accurate control of the lifting process. The heating port 27 on the right side of the outer wall of the battery box 3 can be used to provide heating function for the inside of the battery box 3 under certain environment or condition. The communication port 28 is used to connect external communication equipment or line to realize data transmission and communication between the battery box 3 and the external system, so as to monitor and manage the state of the battery box 3.

[0040] Working principle: first, after the crane 1 starts, the power system drives the horizontal movement of the lifting arm 4, and the moving take-up box 5 is sent to the appropriate position directly above the battery box 3. Then, the moving take-up box 5 is unwound, and the components such as the metering scale 7 and the hook 8 connected below the steel wire 6 are lowered under the action of gravity. The hook 8 is lowered to the appropriate height and is clamped with the lifting ring 11 of the moving sleeve 10. Then, the operator operates the adjusting mechanism 2 according to the size and shape of the battery box 3, rotates the bolt 204 by rotating the handle 205, and makes the moving seat 14 slide in the reserved groove 202, so as to drive the hook 16 to change position to match the lug 17 of the battery box 3. After adjustment, the hook 16 is connected and fixed with the lug 17, the moving take-up box 5 is reeled, the steel wire 6 is reeled to generate tension, and the battery box 3 is lifted in turn through the components such as the hook 8. During the lifting process, the metering scale 7 senses the tension in real time and converts it into weight data. The combination structure of the transverse rod 9, the longitudinal rod 12 and the moving sleeve 10 makes the hook position flexible, which can adapt to different battery boxes 3. Multiple hooks evenly share the weight, which ensures the stability and balance of lifting, reduces shaking and tilting, etc.

[0041] When it is necessary to adjust the distance of the moving seat 14, the operator holds the rotating handle 205 and applies force to make it rotate, thereby driving the bolt 204 to rotate. Since the bolt 204 is threadedly connected with the moving seat 14, the thread interaction generated by the rotation of the bolt 204 will form a pushing force. However, the reserved groove 202 prevents the moving seat 14 from rotating with the bolt 204, so the pushing force promotes the moving seat 14 to slide in the reserved groove 202. During the sliding of the moving seat 14, the limiting blocks 201 on the left and right sides of the outer wall of the moving seat 14 will slide in the limiting grooves 203 synchronously. The limiting blocks 201 and the limiting grooves 203 are closely matched, effectively preventing the rotation of the moving seat 14, and ensuring that the moving seat 14 can only move accurately along the straight line direction specified by the reserved groove 202. After the position of the moving seat 14 is changed, the position of the hook 16 connected with it is also changed, thereby adjusting the distribution pattern of the hook 16. According to different sizes and shapes of the lithium battery box 3, the position of the hook 16 can be flexibly changed to ensure stable and reliable lifting of the battery box 3, and to ensure the smooth progress of the lifting work.

[0042] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
