[0082] Reference Figure 1 In this embodiment, the maintenance tool is placed on the top of the container, and the height is adjusted by adjusting the support column 32 at the bottom to complete the positioning of the maintenance tool. Start the motor, the motor drives the wire rope 532, the wire rope 532 drives the hanger 54, the hanger 54 drives the battery tray 51, and the battery tray 51 is adjusted to the position where the battery pack 6 needs to be replaced; then the battery pack 6 is pulled out onto the battery tray 51 through the push-pull assembly 52 on the battery tray 51, the battery tray 51 is lowered to the ground, and a new battery pack 6 is replaced; then the battery tray 51 is raised to the corresponding position for replacing the battery pack 6, and the battery pack 6 is pushed into the replacement position in the box through the push-pull assembly 52 on the battery tray 51 to complete the replacement of the battery pack 6. The adjustment process is reduced, work efficiency is improved, and the problem of the battery pack 6 not being able to be accurately positioned due to uneven foundation or road surface is solved. The maintenance tool has the advantages of simple installation, portability, and simple adjustment.

[0083] Specifically, Figure 1One end of the force-bearing position of the middle tooling is at the top of the box, and the height is adjusted by maintaining the two adjustment support columns at the bottom of the tooling.

[0084] The tooling is equipped with universal wheels 31 and can move forward, backward, left and right. Some components are installed on the box body and the whole is assembled to reduce the assembly time during use.

[0085] The structure is simple, occupies little space, and does not affect the maintenance and inspection of the battery packs 6 on the left and right sides of the maintenance tool.

[0086] After the protective platform is installed, it can be moved up and down, left and right to adjust the position of the battery pack 6.

[0087] After the battery pack 6 is hoisted into the air, the bottom tray rises and the alignment position can be adjusted manually or electrically, including front and back, left and right, up and down adjustments. The battery pack 6 can be pushed manually or electrically to the corresponding position inside the box.

[0088] Installation interfaces for maintenance tools may be reserved on the box, including but not limited to climbing mechanisms, adjustment mechanisms, and protective measures to prevent the box from being damaged.

[0089] In a preferred embodiment, an anti-collision structure is provided at one end of the battery tray 51 close to the energy storage container 1, which can be adjusted within a small range in four directions: forward, backward, left and right. The battery tray 51 can be corrected when facing slight position deviations, thereby effectively protecting the energy storage container 1 from damage due to collision or extrusion.

[0090] In a preferred embodiment, referring to Figure 2 , the movable component 3 includes,

[0091] The guide rail 37 is provided on the top of the support frame 2 along the length direction of the energy storage container 1;

[0092] Gear 38 is provided at the bottom of the driving assembly 4, and the driving assembly 4 slides on the guide rail 37 through the gear 38;

[0093] The driving assembly 4 includes,

[0094] A first motor connected to the gear 38 to drive the gear 38 to move left and right;

[0095] A second motor is connected to the battery tray 51 and is used to drive the battery tray 51 to rise and fall;

[0096] The supporting frame 2 comprises,

[0097] The supporting connecting rod 21 is located at the top of the energy storage container 1 and extends outward along the width direction of the energy storage container 1 to form an extended end;

[0098] A first support frame 22, wherein a first end of the first support frame 22 is connected to the bottom of the energy storage container 1, and a second end of the first support frame 22 is connected to the extension end;

[0099] A second support frame 23, wherein a first end of the second support frame 23 is connected to the support link 21, and a second end of the second support frame 23 is connected to the first support frame 22;

[0100] The ground auxiliary support frame 24 is vertically arranged between the extension end and the ground.

[0101] Specifically, the supporting link 21, the first supporting frame 22, the second supporting frame 23, the driving assembly 4, and the guide rail 37 are installed on the box body, so that the maintenance tool is based on the top as the reference plane, and the ground auxiliary support frame 24 is added as an auxiliary support to ensure safety. The driving assembly 4 contacts the guide rail 37 through the gear 38. The driving assembly 4 is equipped with a first motor, and the first motor drives the gear 38 to move left and right; in this embodiment, the transmission assembly 53 is a steel wire rope 532 connected to the gear 38 respectively, and the driving assembly 4 is equipped with a second motor. The second motor drives the steel wire rope 532, and the steel wire rope 532 is connected to the battery tray 51. The battery tray 51 is raised and lowered by controlling the second motor. There are gears 38 and push-pull rods 522 on the battery tray 51. The battery pack 6 is pushed in and pulled out by turning the handle 521.

[0102] The wheels at the bottom of the tooling can be increased with height-adjustable screw rods or hydraulic mechanisms, so that the entire maintenance tooling can move left and right along the top guide rail of the box.

[0103] Specifically, the adjustable height mechanism (such as a screw or hydraulic device) of the bottom wheels allows the tooling to move smoothly on the guide rails 37 on the top of the energy storage container 1. By adjusting the height, the position of the tooling and the battery pack 6 can be accurately aligned to ensure that the tooling will not be damaged or inconvenient to operate due to height mismatch during movement.

[0104] Reference Figure 2 In this embodiment, after the maintenance tooling is installed, the tray is raised to the corresponding position for replacing the battery pack 6 by the wire rope 532 of the lifting mechanism 5, and then the battery pack 6 is pulled out onto the tray by the push-pull assembly 52, and the tray is lowered to the ground, and a new battery pack 6 is replaced. Then, the tray is raised to the predetermined position, and the battery pack 6 is pushed into the box by the push-pull assembly 52 to complete the replacement of the battery pack 6.

[0105] Specifically, the top of the container serves as a reference plane to support the lifting and advancement of the battery pack 6. The position of the battery pack 6 within the container is fixed relative to the top and bottom of the container, but not relative to the ground. Using the container as a reference plane eliminates the problem of tilting during battery replacement caused by uneven ground, and uses the ground as auxiliary support to ensure safety.

[0106] It can be installed on the box (through a pull rod, iron chain, steel wire rope 532, cloth belt), and the force-bearing position can be at the top, back, front and corner tips of the two sides of the equipment or on other positions on the box such as horizontal beams and vertical beams; the force-bearing part is transferred to the position described above through an intermediate connecting rod or a slide rail mechanism, or a maintenance tool interface is reserved on the box, so that the battery pack 6 can be maintained away from the ground, or a maintenance tool with auxiliary support parts in contact with the ground can be added.

[0107] The utility model is installed on the energy storage container 1 and can be disassembled and assembled, thereby reducing the space occupied by transportation or installation; it can be overlapped on two adjacent energy storage containers 1, and the bottom can be separated from the ground for maintenance of the battery pack 6.

[0108] After installation, the maintenance platform can be moved up and down, left and right to adjust the position of the battery pack 6.

[0109] After the battery pack 6 is hoisted into the air, the bottom tray rises and the alignment position can be adjusted manually or electrically, including front, back, left, right, up and down adjustments. The battery pack 6 can be pushed manually or electrically to the corresponding position inside the box.

[0110] It has the conditions for industrial and commercial single-machine maintenance (width within 1.5m), non-standard 20-foot container, reserved maintenance tooling interface on the box body, and a slide rail or pulley or other left and right movable structure on the top.

[0111] In summary, the present application provides a movable energy storage battery pack maintenance tool, which uses the top of the box as the reference plane, the movable component 3 as the auxiliary component, and the transmission component 53 to support the lifting and propulsion of the battery pack 6, thereby solving the problem of tool tilting during battery replacement.
