[0029] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] An embodiment of the present application provides an on-site loading and unloading device for an energy storage battery PACK, which can solve the problem in the prior art that the disassembly and maintenance of the energy storage battery Pack is inconvenient.

[0031] Reference Figure 1 The present application discloses an on-site loading and unloading device for an energy storage battery PACK, comprising a fixed support frame 1, a battery holding tray 2, a height driving member, two clamping rods 21, and a dragging mechanism. A guide groove 11 is provided on the vertical support arm of the fixed support frame 1 along the height direction of the fixed support frame 1. The battery holding tray 2 is slidably arranged in the guide groove 11. The battery holding tray 2 is used to place the battery pack to be removed. The height driving member is fixed on the fixed support frame 1 and connected to the battery holding tray 2 to drive the battery holding tray 2 to slide along the height direction of the fixed support frame 1, thereby changing the height of the battery holding tray 2 so that the battery holding tray 2 can adapt to the heights of different battery packs to be removed; the two clamping rods 21 can guide the battery packs on the battery holding tray 2, reducing the possibility of the battery packs slipping off the battery holding tray 2; the dragging mechanism includes a moving slider 22, a dragging driving assembly and a dragging hook 221. The moving slider 22 is arranged on the battery holding tray 2 and is located between the two clamping rods 21. The dragging driving assembly can drive the moving slider to move along the length direction of the battery holding tray 2. The dragging hook 221 is fixed on the moving slider 22.

[0032] When dismantling the energy storage battery pack, first use the height drive to push the battery holding tray 2 to a height that matches the battery pack to be removed, and use the drag drive component to push the movable slider 22 to a position adjacent to the battery pack to be removed, and hang the drag hook 221 on the hook of the hydraulic plate of the battery pack to be removed, and then use the drag drive component to drag the battery pack to be removed to the battery holding tray 2, and then use the height drive component to move the battery holding tray 2 to the bottom of the fixed support frame 1, so that the operator can repair or replace the removed battery pack. After the repair is completed, the same process can be used to push the battery pack to its original position through the drag drive component, and only manual auxiliary clamping is required. The overall operation process is simple and very convenient to use.

[0033] In this embodiment, in order to increase the service life of the fixed support frame 1 and the battery holding tray 2, the fixed support frame 1 is made of a steel structure, and the battery holding tray 2 is made of a Teflon plate.

[0034] The height-actuating element is specifically configured as a driving hydraulic cylinder 12. The output shaft of the driving hydraulic cylinder 12 is connected to the battery tray 2. The output shaft of the driving hydraulic cylinder 12 extends outward to push the battery tray 2 upward. This structure is simple and easy to operate. In this embodiment, two driving hydraulic cylinders 12 are specifically provided. These two driving hydraulic cylinders 12 are bolted to either side of the fixed support frame 1 in the width direction to more smoothly move the battery tray 2. A connecting rod is fixed to the output end of the driving hydraulic cylinder 12. The connecting rod principle connects one end of the driving hydraulic cylinder 12 to the battery tray 2. This ensures a certain distance between the battery tray 2 and the output end of the driving hydraulic cylinder 12, reducing the possibility of contact between the battery tray 2 and the output end of the driving hydraulic cylinder 12 and lowering the maximum height of the battery tray 2 from the ground, making it easier for operators to operate.

[0035] Reference Figure 2 In this embodiment, a guide rod 23 is provided between the two clamping rods 21 of the battery holding tray 2. The length direction of the guide rod 23 is parallel to the length direction of the battery holding tray 2. The movable slider 22 is threadedly inserted into the guide rod 23, and the guide rod 23 is rotatably provided on the battery holding tray 2. The dragging drive component includes a reciprocating motor 24. The reciprocating motor 24 is fixed to the battery holding tray 2 by bolts, and the output shaft of the reciprocating motor 24 extends from the bottom plate of the battery holding tray 2 and is coaxially connected to the guide rod 23. When the reciprocating motor 24 is turned on, the guide rod 23 rotates with the output shaft of the reciprocating motor 24, so that the movable slider 22 can move along the length direction of the guide rod 23 to push the movable slider 22 to the side of the battery holding tray 2 close to the battery pack to be removed. The structure is simple, very convenient to use, and easy to operate.

[0036] In order to adapt to the different widths of the battery pack to be removed, refer to Figure 2 The two clamping rods 21 are slidably mounted on the battery tray 2 along its width. The battery tray 2 is also provided with a width adjustment assembly for adjusting the spacing between the two clamping rods 21. The width adjustment assembly includes a slide rail 25 and a rotary handle 26. The slide rail 25 is mounted on the battery tray 2 along its width. In this embodiment, four slide rails 25 are provided, one on each side of a single clamping rod 21, to facilitate movement of the clamping rod 21. The rotary handle 26 is threadedly mounted on the battery tray 2, and one end of the rotary handle 26 penetrates the battery tray 2 and is connected to the clamping rod 21. The operator can push the clamping rod 21 to move on the slide rail 25 by rotating the rotary handle 26. In this embodiment, fixed plates are vertically welded at both ends of the battery tray 2 in the length direction, and the rotating handle 26 is threadedly bolted on the fixed plate. A fixing plate is connected to the clamping rod 21. The rotating handle 26 is connected to the fixing plate, and while pushing the clamping rod 21, the clamping position of the clamping rod 21 is increased to better clamp the battery pack on the battery tray 2.

[0037] Since multiple battery packs to be removed are located at different positions during maintenance work on the energy storage battery PACK, a universal wheel 13 is provided at the bottom of the fixed support frame 1 to facilitate the removal of the energy storage battery PACKs at different positions by the operator. In this embodiment, the universal wheel 13 is electrically driven, making it easier for the operator to control the fixed support frame 1 and saving effort. In order to facilitate the fixing of various electrical drive devices on the fixed support frame 1, the fixed support frame 1 is also provided with a power control cabinet 3. The power control cabinet 3 contains a control motor that controls the movement of the universal wheel 13. A control panel can also be added to the power control cabinet 3, and the control motor of the universal wheel 13 and the drag drive motor can be connected within the control program of the control panel, making it easier to centrally control various components and more convenient to use.

[0038] In order to enable the fixed support frame 1 to be temporarily fixed on the ground more stably and reduce the possibility of the fixed support frame 1 shaking, a support foot 14 is also provided at the bottom of the fixed support frame 1. In this embodiment, a storage box is provided at the bottom of the fixed support frame 1, and the support foot 14 is movably inserted in the storage box. When it is necessary to perform vertex positioning of the fixed support frame 1 to complete the disassembly and assembly operation, the support frame is pulled out of the storage box to complete the temporary support of the fixed support frame 1.
