Description

Technical Field

[0001] This utility model belongs to the field of energy storage box technology, and in particular relates to an energy storage box battery pack installation fixture. Background Technology

[0002] The energy storage box is an outdoor intelligent substation on the grid side, consisting of components such as a charger, inverter, battery, isolation transformer, and switches. For example... Figure 1 , 2 As shown, the battery is equipped with an outer casing, and there are connectors 02 on both sides of the casing. The casing, connectors 02, battery interface and other components constitute a battery pack 01. Multiple battery packs 01 are installed in the battery cabinet 03 inside the energy storage box.

[0003] The energy storage box and its internal secondary equipment can be assembled in the factory. 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, the forklift is operated to lift the forklift arm to send the battery pack to the designated position on each layer of the battery cabinet. The forklift arm is lowered so that the connecting parts 02 on both sides of the battery pack 01 are mounted on the mounting frame 04 of the battery cabinet 03. Finally, the connecting parts 02 and the mounting frame 04 are fixed with bolts.

[0004] However, due to the limited space inside the battery cabinet, the forklift arm has limited room to move between the mounting racks inside the cabinet when pushing the battery pack. Furthermore, it is difficult for the forklift to make small lateral or longitudinal distance adjustments. In order to push the battery pack to the designated position, frequent adjustments are required, which causes the forklift arm to frequently collide with the mounting racks or the already installed battery packs. In severe cases, this can cause deformation and damage to the outer shell of the installed battery packs, affecting assembly efficiency. Utility Model Content

[0005] This utility model provides a tooling for installing battery packs in an energy storage box, aiming to solve the above-mentioned technical problems.

[0006] This utility model is implemented as follows: an energy storage box battery pack installation fixture includes a workbench, a hydraulic lift, a pallet cart for carrying the battery pack, and a rail flatcar for carrying the battery cabinet. The base of the hydraulic lift is fixed on the workbench. The hydraulic lift has an L-shaped lifting arm. The horizontal part of the lifting arm is connected to a rail plate. A first rail is provided on the top surface of the rail plate. The pallet cart moves along the first rail. A second rail is provided on the top surface of the workbench. The rail flatcar moves along the second rail. The second rail extends toward the hydraulic lift and is parallel to the first rail.

[0007] Furthermore, multiple reinforcing ribs connect the bottom surface of the track plate to the lifting arm.

[0008] Furthermore, the pallet truck has a limiting groove on its top surface, the length of which matches the length of the battery pack.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] See Figures 3-7 This utility model provides a battery pack installation fixture for an energy storage box, used to place battery packs into the battery cabinet layer by layer. The fixture includes a workbench 1, a hydraulic lift 2, a pallet cart 3, and a rail flatcar 7.

[0029] The workbench 1 is fixed on the ground, and the base of the hydraulic lift 2 is fixed to the workbench 1 with bolts. The hydraulic lift 2 is used to lift the battery pack and push it to the mounting frame inside the battery cabinet. The hydraulic lift 2 can be a single-column hydraulic fixed car lift in the prior art.

[0030] The pallet truck 3 is used to carry the battery pack. The hydraulic lifter 2 lifts the pallet truck 3 and the battery pack together to the designated height, and then pushes the pallet truck 3 to send the battery pack to the mounting rack in the battery cabinet.

[0031] The rail flatcar 7 is used to move the battery cabinet toward or away from the hydraulic lift 2, assisting the hydraulic lift 2 in installing the battery pack.

[0032] The hydraulic lift 2 has an L-shaped lifting arm 3. The horizontal part of the lifting arm 3 is connected to a track plate 4. The top surface of the track plate 4 is provided with a first track 5. The pallet trolley 6 moves along the first track 5.

[0033] In this embodiment of the invention, the length of the horizontal portion of the lifting arm 3 and the track plate 4 is greater than the sum of the length of the battery pack and the length of the battery cabinet. To ensure the stability of the hydraulic lift 2 during use, the length of the base of the hydraulic lift 2 parallel to the lifting arm 3 is adaptively adjusted according to the increase in the length of the lifting arm 3. Two parallel first tracks 5 are provided on the top of the track plate 4. The first track 5 is a groove. Two sets of directional wheels 11 are connected to the bottom of the pallet trolley 6. The directional wheels 11 roll in a directional manner within the groove. The centerline of the lifting arm 3 is collinear with the centerline of the two first tracks 5 and the centerline of the pallet trolley 7.

[0034] To ensure the strength of the track plate 4, in one embodiment of this utility model, multiple reinforcing ribs 9 are connected between the bottom surface of the track plate 4 and the lifting arm 3.

[0035] In addition, a limiting groove 10 is provided on the top surface of the pallet truck 6, and the length of the limiting groove 10 matches the length of the battery pack 01. When the pallet truck 6 carries the battery pack, the limiting groove 10 can be used to quickly position the battery pack, ensuring that the battery pack can enter the battery cabinet with the pallet truck 6 at an angle facing the battery cabinet.

[0036] The pallet truck 6 is connected to a push-pull handle 12 at one end near the hydraulic lift 2. The push-pull handle 12 makes it easy for installation workers to push and pull the pallet truck 6. After the pallet truck 6 enters the battery cabinet, the push-pull handle 12 can be used to finely adjust the position of the pallet truck 6, and thus finely adjust the position of the battery pack.

[0037] A center point mark 13 is provided on the top surface of the pallet truck 6 near the hydraulic lift 2. Before the battery pack is placed on the pallet truck 6, the center line of the battery pack is drawn on the front edge of the battery pack. When the battery pack is placed on the pallet truck 6, the center point mark 13 is used to align with the center line drawn on the battery pack. In conjunction with the aforementioned limiting groove 10, the relative position of the battery pack on the pallet truck 6 and the mounting rack in the battery cabinet can be more accurately positioned.

[0038] In another embodiment of this utility model, a stop bar 15 is provided at the end of the first track 5 away from the hydraulic lift 2 to prevent the pallet truck 6 from moving.

[0039] The stop bar 15 is located at the end of the first track 15, which allows the pallet trolley 6 to be moved out of the first track 15, ensuring safety.

[0040] The top surface of the workbench 1 is provided with a second track 8. The track flatcar 7 moves along the second track 8. The second track 8 extends toward the hydraulic lift 2 and is parallel to the first track 5.

[0041] The rail flatcar 7 can be a battery-powered flatcar from the existing technology, equipped with an industrial wireless remote control device, which can remotely control the rail flatcar 7 to move forward along the second track 8 to approach the hydraulic lift 2 or to move backward to move away from the hydraulic lift 2.

[0042] In this embodiment of the utility model, the top surface of the track flat car 7 is provided with a positioning mark 14 that matches the length and width of the battery cabinet 03. The center line of the positioning mark 14 is parallel to the second track 8 and is located in the same plane as the center point mark 13.

[0043] The positioning mark 14 on the rail flatcar 7 can help align the centerline of the battery cabinet and its internal mounting frame with the centerline of the lifting arm 3 of the hydraulic lift 2.

[0044] In summary, see Figures 8-11 The battery pack installation fixture provided in this embodiment of the utility model places the battery pack 01 layer by layer from top to bottom in the battery cabinet 03. Before use, the fixture is configured as follows: lifting arm 3, track plate 4, two first tracks 5, pallet cart 6, track flatcar 7, two second tracks 8, center point mark 13, and the center line or point of positioning mark 14 are collinear.

[0045] The specific working process is as follows: The remote-controlled rail flatcar 7 moves away from the hydraulic lift 2, and the battery cabinet 03 is placed on the rail flatcar 7 using a crane, aligning the battery cabinet 03 with the pre-set positioning mark 14. The remote-controlled rail flatcar 7 slowly moves towards the hydraulic lift 2, so that the front end of the lifting arm 3 on the hydraulic lift 2 extends into the battery cabinet until the front end of the first rail 5 on the lifting arm 3 reaches the end of the mounting frame 04 of the battery cabinet 03. The lifting arm 3 is lifted and fixed at the uppermost mounting frame 04 inside the battery cabinet 03, and the pallet cart 6 moves back to the vertical part of the L-shaped lifting arm 3. The center line position is marked on the front edge of the battery pack 01 beforehand, and the battery pack 01 is placed on the pallet cart 6 using a crane, aligning the battery pack 01 into the limiting groove 10, and aligning the center line position of the battery pack 01 with the center point mark 13 on the pallet cart 6. At this time, the bottom height of the battery pack 01 is slightly greater than the upper surface height of the mounting frame 04 inside the battery cabinet 03. Push the push-pull handle 12 to allow the pallet trolley 6 to carry the battery pack 01 into the battery cabinet 03. Use the push-pull handle 12 to fine-tune the relative position of the battery pack 01 and the mounting bracket 04. Once the designated position is reached, lower the lifting arm 3. The pallet trolley 6 and the battery pack 01 will descend together. Since the width of the lifting arm 3 and the pallet trolley 6 is less than the distance between the two mounting brackets 04, and the width of the connecting parts 02 on both sides of the battery pack 01 is greater than the distance between the two mounting brackets 04, the connecting parts 02 on both sides of the battery pack 01 will fall onto the mounting brackets 04. Secure the connecting parts 02 to the mounting brackets 04 with bolts to complete the installation of the battery pack 01 for that layer. Then pull out the pallet trolley 6 and repeat the above steps, gradually lowering the lifting arm 3 to complete the installation of the battery packs 01 for each layer.

[0046] After all battery packs 01 are installed, move the remote-controlled rail flatcar 7 away from the hydraulic lift 2, so that the lifting arm 3 on the hydraulic lift 2 leaves the inside of the battery cabinet 03, and then use a crane to move the battery cabinet 03 away.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
