[0002] The energy storage box is an outdoor smart substation on the grid side, consisting of chargers, inverters, batteries, isolation transformers, switches and other components. Figures 1 to 3 As shown, the storage battery is encapsulated in a battery pack 01, the bottom of the outer shell of the battery pack 01 extends outward to form a connector 02, a battery cabinet 03 is provided inside the energy storage box, brackets 04 are installed on both sides of the inside of the battery cabinet 03, the connectors 02 on both sides of the battery pack 01 are connected to the bracket 04, and multiple battery packs 01 are installed inside the battery cabinet 03.

[0003] The energy storage box and its internal secondary equipment can be factory assembled. When installing the battery pack, the existing technology usually uses a crane to lift the battery pack and place it on the forklift arm, then controls the forklift to lift the forklift arm to deliver the battery pack to the designated position on each layer in the battery cabinet, lowers the forklift arm so that the connectors on both sides of the battery pack fall on the bracket of the battery cabinet, and finally fixes the connector and the bracket with bolts.

[0004] However, due to the small space inside the battery cabinet, the forklift arm has limited room to move between the brackets inside the battery cabinet when pushing the battery pack, and it is difficult for the forklift to make small lateral or longitudinal distance adjustments. Frequent adjustments are required to push the battery pack to the specified position, causing the forklift arm to often collide with the bracket or the installed battery pack. In severe cases, the shell of the installed battery pack is deformed and damaged, affecting assembly efficiency. Summary of the invention

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0037] See also Figures 5 to 9 An embodiment of the present invention provides an energy storage box battery pack installation tool, which is used to assist in the installation of battery packs layer by layer in a battery cabinet. The tool includes a battery mounting frame 1, a track plate 2 and a tray tool 3. The track plate 2 can be detachably installed inside the battery mounting frame 1 and can be aligned with the bracket in each layer of the battery cabinet. The tray tool 3 moves on the track plate 2, and the battery pack is placed on the tray tool 3 to push the battery pack onto the bracket in the battery cabinet.

[0038] The top of the battery mounting rack 1 is open, and multiple layers of detachable first cross beams 101 are connected to the battery mounting rack 1 in the vertical direction. The heights of the multiple layers of first cross beams 101 match the heights of the brackets in each layer in the battery cabinet.

[0039] The open space at the top of the battery mounting rack 1 is used for a crane to lift the battery pack from this space into the battery mounting rack 1 , and then place the battery pack on the tray tooling 3 .

[0040] In an embodiment of the present invention, the detachable connection method of the first cross beam 101 is that a plurality of limit blocks 102 are relatively connected to the inner side of the battery mounting frame 1 in the vertical direction, and the cross section of the first cross beam 101 has a U-shaped structure, and the two ends of the U-shaped structure of the first cross beam 101 are buckled on the limit blocks 102, and the two ends of the first cross beam 101 and the limit blocks 102 are respectively provided with corresponding first fixing holes.

[0041] The two ends of the three first beams 101 are buckled on the limit blocks 102 on both sides of the battery mounting frame 1 to support the track plate 2. In order to ensure the buckling stability, the first beams 101 and the limit blocks 102 can be connected by bolts in the first fixing holes.

[0042] The two track plates 2 are respectively mounted on the first cross beam 101 and the bracket. The surfaces of the track plates 2 are connected with tracks 201 , and the tracks 201 on the two track plates 2 are connected to each other.

[0043] The front ends of the two track plates 2 are relatively fitted and aligned with each other, the tracks 201 on the track plates 2 are aligned and connected, and the pallet tooling 3 moves on the two connected sections of the track 201 .

[0044] In the embodiment of the present invention, a plurality of second cross beams 103 are fixedly connected to the side surface of the battery mounting rack 1 along the vertical direction, and the height of the second cross beams 103 is greater than the height of the first cross beams 101 .

[0045] When the tray tool 3 moves on the track plate 2 , the second crossbeam 103 is used to block the tray tool 3 from moving out of the battery mounting rack 1 .

[0046] In addition, in order to better fix the track plate 2, in an embodiment of the present invention, a baffle 202 is provided on one side of the track plate 2 perpendicular to the track 201, and the cross-section of the baffle 202 has a U-shaped structure. The U-shaped structure of the baffle 202 is buckled on the second cross beam 103, and corresponding second fixing holes are respectively provided at both ends of the baffle 202 and the second cross beam 103.

[0047] The track plate 2 can use the baffle 202 to limit the moving space of the pallet tooling 3, and can also limit the track plate 2 by buckling the baffle 202 with the second cross beam 103. If necessary, the baffle 202 and the second cross beam 103 are connected by bolts in the second fixing hole to fix the track plate 2.

[0048] In addition, third fixing holes are respectively opened on both sides of one end of the track plate 2 away from the blocking bar 202 , and the third fixing holes on the two track plates 2 are detachably connected through a pair of connecting plates 203 and bolts.

[0049] The two sides of the butt joint at the front ends of the two track plates 2 are connected as a whole by using a connecting plate 203 and bolts to fix the relative positions of the two track plates 2.

[0050] like Figure 4 As shown, in order to fix the battery pack, a limiting device 05 for limiting the position of the battery pack is installed on the bracket 04 in the battery cabinet 03, and the tail end of the limiting device 05 has a limiting portion 06, and the limiting portion 06 has an opening. For this, in the embodiment of the present invention, the spacing and position of the third fixing hole on the stop bar 202 of the track plate 2 installed on one side of the battery cabinet 03 match the position of the opening, and the track plate 2 on one side of the battery cabinet 03 is fixed by bolts connected with the opening.

[0051] See also Figures 10 to 14 The pallet tooling 3 includes a fixed plate 301 and a movable plate 302. The movable plate 302 is connected to the fixed plate 301 through a height-adjustable lifting component 303. A directional wheel 304 is installed at the bottom of the fixed plate 301. The directional wheel 304 moves along the track 201, and the battery pack is placed on the movable plate 302.

[0052] The pallet fixture 3 is a cart with an adjustable height of the movable plate 302. The pallet fixture 3 moves along the track 201 using the directional wheels 304, and the overall width is less than the spacing between the brackets on both sides of the battery cabinet. The battery pack is placed on the pallet fixture 3, and the lifting assembly 303 is used to lift the battery pack. When installing the first layer of battery packs, the track plate 2 on one side of the battery cabinet is mounted on the second layer of brackets in the battery cabinet. The first crossbeam 101 and the second crossbeam 103 support the track plate 2 in the battery mounting frame 1 so that the two track plates 2 remain horizontal. The pallet fixture 3 pushes the battery pack into the battery cabinet along the track 201 on the track plate 2. When entering, the pallet fixture 3 lifts the battery pack so that the bottom surface of the connectors on both sides of the battery pack is slightly higher than the top surface of the bracket. After the battery pack is pushed into place, the lifting assembly 303 lowers the height of the movable plate 302 so that the connectors on both sides of the battery pack fall on the bracket, thereby realizing the auxiliary installation of the battery pack.

[0053] The track 201 in the embodiment of the present invention can be detachably connected to the track plate 2. For battery cabinets with different distances between two adjacent layers, in order to make the height of the battery pack lifted by the pallet tooling 3 greater than the bracket, tracks 201 of different heights can be used.

[0054] Regarding the lifting component 303, in the embodiment of the present invention, specifically, the lifting component 303 includes a pushing rod 3031 and a pushing block 3032, two pairs of pushing blocks 3032 are respectively slidably connected on both sides of the fixed plate 301, the surface of the pushing rod 3031 has an external thread, the two pushing rods 3031 are respectively threadedly connected to the two pairs of pushing blocks 3032, and the bottom surface of the movable plate 302 is connected with a lifting block 3033 at a position corresponding to the pushing block 3032, and the lifting block 3033 and the pushing block 3032 have an inclined surface and a plane structure that can slide in contact with each other.

[0055] The fixed plate 301 and the movable plate 302 are both hollow U-shaped structures. Pairs of track blocks are fixedly connected to the top surfaces of both sides of the fixed plate 301, and the bottom of the push block 3032 slides between the two track blocks. The push rod 3031 is threadedly connected to the push block 3032. By adjusting the threaded connection mode, the embodiment of the present invention is set so that when the push rods 3031 on both sides are rotated in the same direction, all the push blocks 3032 move in the same direction.

[0056] The sliding contact between the lifting block 3033 and the pushing block 3032 on the inclined plane can change the overall height, and after reaching the maximum height, as the pushing block 3032 continues to move, the lifting block 3033 and the pushing block 3032 planes conflict with each other, achieving a stable supporting state of the pushing block 3032 for the lifting block 3033.

[0057] In order to conveniently control the rotation of the two push rods 3031 and push or pull the pallet tooling 3 , one end of the two push rods 3031 is respectively locked and rotatably connected to a wrench 305 , and the ends of the two wrenches 305 are rotatably connected to a lifting operating rod 306 .

[0058] When the lifting operating rod 306 is translated, the wrench 305 is driven to swing, thereby driving the propulsion rod 3031 to rotate, and the rotation of the propulsion rod 3031 drives the propulsion block 3032 to move. After the lifting operating rod 306 is translated, the overall width of the tray tooling 3 is smaller than the spacing between the columns on both sides of the battery cabinet.

[0059] In order to prevent the propulsion block 3032 from being separated from the track block on which it is sliding, two pairs of first limit plates 3034 are respectively connected to both sides of the fixed plate 301 in the embodiment of the present invention, and each pair of first limit plates 3034 is arranged at both ends of the sliding direction of the propulsion block 3032. The positions of the first limit plates 3034 are set so that when the propulsion block 3032 moves in one direction to contact one first limit plate 3034, the top surface of the propulsion block 3032 and the bottom surface of the lifting block 3033 reach the maximum overlap area, and when the propulsion block 3032 moves in another direction to contact another first limit plate 3034, the inclined surface of the propulsion block 3032 and the inclined surface of the lifting block 3033 reach the maximum overlap area.

[0060] In order to limit the range of movement of the movable plate 302, in the embodiment of the present invention, the bottom surface of the movable plate 302 is connected to a limiting member 3035, the top surface of the fixed plate 301 is connected to a second limiting plate 3036, and the bottom of the limiting member 3036 passes through the second limiting plate 3036 and is connected to a limiting pin 3037 at the bottom.

[0061] The bottom of the limiting member 3035 has a cylindrical structure, and the second limiting plate 3036 is provided with a hole matching the cylindrical structure. The four limiting members 3035 cooperate with the four second limiting plates 3036 respectively to limit the four corners of the movable plate 302 to avoid horizontal displacement so that it can only move in the vertical direction. The limiting pin 3037 can prevent the limiting member 3035 from separating from the second limiting plate 3036.

[0062] In summary, see Figures 15 to 19 When the energy storage box battery pack installation tool provided by the embodiment of the present invention is used, the battery mounting frame 1 and the battery cabinet 03 are connected. Fig.15 Align in the manner shown, install the first beam 101 on the three pairs of limit blocks 102 on the top layer of the battery mounting frame 1, and screw bolts into the first fixing holes on the first beam 101 and the limit blocks 102 to fix them. Place the track plate 2 on the first beam 101, and the baffle 202 of the track plate 2 is buckled on the second beam 103, align the second fixing holes on the second beam 103 and the baffle 202, and screw bolts in to fix them. Place another track plate 2 on the bracket 04 on the second layer of the battery cabinet 03, align the baffle 202 with the hole on the limit part 06 of the limit device 05, and screw bolts in to fix them. The front ends of the two track plates 2 are butted, and the two tracks 201 on the two track plates 2 are aligned and connected respectively. The two track plates 2 are connected and fixed by screwing bolts into the sides of the front ends of the two track plates 2 using the connecting plate 203. The directional wheels 304 on both sides of the pallet tooling 3 are respectively placed in the tracks 201 on both sides, and the lifting operating rods 306 of the pallet tooling 3 face outwards. After the above steps are completed, the symmetric center lines of the brackets 04 on both sides, the symmetric center lines of the rails 201 on both sides, and the center line of the pallet tooling 3 are located in the same plane.

[0063] Use a crane to hoist the battery pack 01 onto the movable plate 302 of the pallet fixture 3, align the center line of the battery pack 01 with the center line of the pallet fixture 3, translate the lifting and lowering operating rod 306 to drive the wrench 305 to swing, the wrench 305 drives the push rod 3031 to rotate, and the push rod 3031 drives the push block 3032 to move. During the movement, the push block 3032 and the lifting block 3033 transition from inclined sliding contact to flat contact and reach the maximum height, lifting the battery pack 01. Push the pallet fixture 3 into the battery cabinet 03 until the connectors 02 on both sides of the battery pack 01 are completely above the bracket 04, translate the lifting and lowering operating rod 306 in the opposite direction, so that the push block 3032 and the lifting block 3033 transition from flat contact to inclined sliding contact and reach the minimum height, and the battery pack 01 falls on the bracket 04 through the connectors 02 on both sides, completing the pushing of the first layer of battery packs 01. Then remove the pallet tooling 3, disassemble the two track plates 2 and the three pairs of first beams 101, install the first beams 101 and the track plates 2 on the next layer, i.e., the third layer, on the limit blocks 102 and the brackets 04, and then place the pallet tooling 3 on the track 201, repeat the above steps of hoisting and lifting the pallet tooling 3 to complete the pushing of the second layer of battery packs 01. And so on, complete the pushing of each layer of battery packs 01 one by one. The battery packs 01 are not placed on the bottom layer of the battery cabinet 03, and this space is used to install the track plate 2 and the pallet tooling 3 to complete the pushing of the second to last layer of battery packs 01. In the above steps, in order to ensure that the height of the battery pack 01 lifted by the pallet tooling 3 is slightly higher than the height of the bracket 04, the track 201 of an appropriate height is replaced when installing the track plate 2.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
