Description

Technical Field

[0001] This invention relates to the field of energy storage equipment maintenance tooling technology, and in particular to an auxiliary device for battery pack replacement. Background Technology

[0002] In existing energy storage equipment, energy storage compartments generally adopt a container matrix layout, using the energy storage compartment frame to arrange battery packs in layers. As the core component of the energy storage system, the battery pack is installed at a high position and has a large individual weight. When a battery pack fails and needs maintenance, in the past, lifting equipment was usually used to lift the support frame supporting the battery pack to the battery storage compartment of the corresponding replacement battery pack. Then, the electric drive device on the support frame was used to drive the battery pack out of the battery storage compartment. Similarly, during the installation process, the electric drive device was used to drive the battery pack into the battery storage compartment.

[0003] Large lifting equipment is costly to operate and has limited space, making it difficult to maneuver flexibly in the narrow space of the energy storage compartment. Without large lifting equipment, it is difficult for workers to lift the heavy support frame with electric drive to the height corresponding to the battery storage compartment, resulting in a low safety factor. Summary of the Invention

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a battery pack replacement auxiliary device that is convenient and flexible to use, reduces maintenance costs, and improves operational safety.

The device features a flexible pull cord assembly. The support frame is provided with a first hook, and the movable seat is provided with a second hook. The pull cord assembly can have at least a first winding structure and a second winding structure, and can optionally use either the first winding structure or the second winding structure to wind around the first hook and the second hook to form a driven part. In the first winding structure, applying force to the driven part can cause the movable seat to move away from the battery compartment in the disassembly and assembly channel. In the second winding structure, applying force to the driven part can cause the movable seat to move closer to the battery compartment in the disassembly and assembly channel.

[0006] A battery pack replacement auxiliary device according to an embodiment of the present invention has at least the following beneficial effects: This invention relates to a battery pack replacement auxiliary device.

[0023] like Figures 1 to 7As shown, a battery pack 610 replacement auxiliary device according to a first aspect embodiment of the present invention includes a support frame 100, a movable seat 200, and a flexible pull rope assembly 300. The support frame 100 is provided with a first connecting structure 110, which is used to detachably install the support frame 100 onto an energy storage compartment frame 600. The support frame 100 is provided with a disassembly and assembly channel, the end of which is used to dock with a battery accommodating compartment 620 on the energy storage compartment frame 600 for housing the battery pack 610. The movable seat 200 is provided with a second connecting structure 210, which is used to detachably install the movable seat 200 onto the battery pack 610. The movable seat 200 movably... The movable seat 200 is placed on the support frame 100 and can move along the disassembly and assembly channel. The support frame 100 is provided with a first hook 170 and the movable seat 200 is provided with a second hook 220. The pull rope assembly 300 can have at least a first winding structure and a second winding structure, and can optionally use the first winding structure or the second winding structure to be wound around the first hook 170 and the second hook 220 to form a driven part. In the first winding structure, applying force to the driven part can cause the movable seat 200 to move away from the battery compartment 620 in the disassembly and assembly channel. In the second winding structure, applying force to the driven part can cause the movable seat 200 to move closer to the battery compartment 620 in the disassembly and assembly channel.

[0024] Both the support frame 100 and the movable seat 200 can be made of an alloy material with sufficient hardness. The support frame 100 can be frame-shaped, with an extension rod at the rear end. The end of the extension rod is used to install a first connecting structure 110 to connect with the energy storage compartment frame 600. The upper surface of the extension rod and the support frame 100 can support the battery pack 610 to form a disassembly and assembly channel above the extension rod and the support frame 100. The movable seat 200 can be plate-shaped to be stacked on the front of the battery pack 610 and connected by a second connecting structure 210.

[0025] Specifically, such as Figure 3 As shown, the second connection structure 210 includes a third connection hole 212 and a second bolt 211 disposed on the movable seat 200. The third connection hole 212 can correspond to the fourth connection hole on the battery pack 610, and the second bolt 211 passes through the third connection hole 212 and the fourth connection hole.

[0026] The pull rope assembly 300 can be made of natural or artificial fiber materials with high toughness, such as hemp. It can be in the form of a flat cloth or a woven bundle. It is lightweight and can be used to pull objects. The first hook 170 and the second hook 220 can both be in the form of a ring or a semi-ring to facilitate the threading and winding of the pull rope assembly 300.

[0027] The battery pack 610 replacement auxiliary device of the present invention eliminates the need for heavy components such as electric drive devices on the support frame 100, making the replacement auxiliary device lighter and smaller. Workers can flexibly move the replacement auxiliary device to various positions within the energy storage compartment, and the support frame 100 can be manually raised to the height of the battery pack 610 to be replaced. The first connecting structure 110 detachably mounts the support frame 100 to the energy storage compartment frame 600, and then the movable seat 200 is moved to the front of the battery pack 610. The second connecting structure 210 mounts the movable seat 200 to the battery pack 610. The pull rope assembly 300 is connected to the first hook 170 and the second hook 220 respectively to form a first winding structure. Because the pull rope assembly 300 is flexible, workers can pull the driven part in a suitable direction according to their own conditions, thereby causing the battery pack 610 to detach from the battery storage compartment 620 and move to the disassembly and assembly channel. When installing the battery pack 610, the battery pack 610 can be placed in the disassembly and assembly channel of the support frame 100, and the movable seat 200 can be connected to the battery pack 610. The pull rope assembly 300 is connected to the first hook 170 and the second hook 220 respectively to form a second winding structure. Similarly, workers can pull the driven part in a suitable direction according to their own conditions, thereby causing the battery pack 610 to move from the disassembly and assembly channel to be installed into the battery storage compartment 620. This design is convenient and flexible to use, reduces maintenance costs, and improves the safety factor of operation.

[0028] In some embodiments of the present invention, such as Figures 2 to 5 As shown, the support frame 100 is detachably provided with a support frame 400. The battery pack 610 can move along the disassembly and assembly channel to the support frame 400 and be received by the support frame 400. The support frame 400 is provided with a hoisting assembly 410, which is used to connect with a hoisting device. The hoisting device is used to drive the support frame 400 to rise and fall to separate it from the support frame 100.

[0029] The support frame 400 can be placed flat on the support frame 100. When the battery pack 610 is removed from the battery storage compartment 620 and moves along the disassembly and assembly channel, it can be moved to the support frame 400 and supported by the support frame 400. At this time, the hoisting equipment is used to connect the hoisting component 410 and then lift it upward to separate the support frame 400 from the support frame 100. Finally, the staff can take out the battery pack 610 from the support frame 400.

[0030] In some embodiments of the present invention, the hoisting assembly 410 includes a plurality of hoisting rods 420 disposed on the support frame 400 and all facing upward, and the plurality of hoisting rods 420 are distributed on both sides of the disassembly and assembly channel.

[0031] The multiple lifting rods 420 distributed on both sides of the disassembly and assembly channel can limit the battery pack 610. During the hoisting process, the battery pack 610 is not easy to fall off the support frame 400. In addition, the hoisting equipment can keep the support frame 400 in a relatively horizontal state by lifting it with multiple lifting rods 420, which further prevents the battery pack 610 from falling off.

[0032] The hoisting assembly 410 further includes a hoisting bracket 430, multiple elastic slings 440, and multiple hoisting ropes 450. The bottom of the hoisting bracket 430 is provided with multiple first connectors 431. The first ends of the multiple slings 440 are connected to the first connectors 431 one by one, and the tail ends of the multiple slings 440 are detachably connected to the hoisting rod 420 one by one. The top of the hoisting bracket 430 is provided with multiple second connectors 432. The tail ends of the multiple hoisting ropes 450 are connected to the second connectors 432 one by one. The hoisting equipment is connected to the first ends of the multiple hoisting ropes 450. The lengths of each hoisting rope 450 are all equal, partially equal, or all unequal.

[0033] The sling 440 can be made of resin materials such as rubber with sufficient tensile strength. Different specifications of battery packs 610 have different heights. The sling 440 is connected to the first connector 431 and the lifting rod 420 respectively. It can adapt to battery packs 610 of different heights through elastic deformation, and make the lifting bracket 430 and the support frame 400 clamp the battery pack 610 from above and below, further preventing the battery pack 610 from falling off. Specifically, the first connector 431 and the second connector 432 can both be buckles or barbs.

[0034] For some battery packs 610, their weight may not be uniform in the horizontal direction. Therefore, the lengths of the lifting ropes 450 connected to the second connectors 432 in different directions are different. For example, in the direction where the battery pack 610 is heavier and tends to tilt downwards, the length of the lifting rope 450 is chosen to be shorter, so that the support frame 400 in that direction is less likely to tilt downwards. Finally, the hoisting equipment is connected to the first ends of the multiple lifting ropes 450, and the support frame 400 is kept horizontal by appropriate adjustment to prevent the battery pack 610 from tilting and falling off.

[0035] In some embodiments of the present invention, such as Figure 6 As shown, in the first winding structure, the first end of the pull rope assembly 300 is connected to the second hook 220, and the tail end of the pull rope assembly 300 passes through the first hook 170 and forms the driven part.

[0036] Specifically, the first end of the pull rope assembly 300 can be tied to the second hook 220. Then, when the worker is positioned below the support frame 100 and pulls the driven part, the pull rope assembly 300 can pull the battery pack 610 from the battery storage compartment 620 to the disassembly and assembly channel.

[0037] In some embodiments of the present invention, such as Figure 7 As shown, the support frame 100 is provided with a first winding part 180 and a second winding part 190 at a position close to the docking position of the disassembly and assembly channel and the battery storage compartment 620. The first winding part 180 and the second winding part 190 are respectively located on the left and right sides of the disassembly and assembly channel. In the second winding structure, the pull rope assembly 300 is sequentially passed through the first winding part 180, the second hook part 220 and the second winding part 190. The first and last ends of the pull rope assembly 300 are connected and pass through the first hook part 170 to form the driven part.

[0038] The first connecting part 180 and the second connecting part can be columnar. It is understood that the movable seat 200 and the battery pack 610 are located outside the annular pull rope assembly 300. When the operator pulls the driven part, the battery pack 610 located in the disassembly and assembly channel will be pushed backward by the pull rope assembly 300 towards the battery storage compartment 620, so that the battery pack 610 is installed into the battery storage compartment 620.

[0039] Specifically, after the first and last ends of the pull rope assembly 300 are connected, either end can be extended through the first hook 170 to form the driven part, without both ends needing to be connected.

[0040] In addition, whether it is the first or the second winding structure, a pulley block 310 can be provided on the first hook 170. The pull rope assembly 300 can be threaded through the pulley block 310 and then through the first hook 170, or the pull rope assembly 300 can be threaded through the pulley block 310 to connect with the first hook 170. The operator can use the pulley block 310 to apply force to the battery pack, thereby reducing the force required by the operator to pull and push the battery pack 610 which has a larger weight.

[0041] In some embodiments of the present invention, such as Figures 5 to 7 As shown, the support frame 100 protrudes from the end of the disassembly and assembly channel away from the battery storage compartment 620 and is provided with a drive support 500, and the first hook 170 is provided on the drive support 500.

[0042] The drive support bracket 500 protrudes from the support frame 100 and also protrudes in the direction away from the battery compartment 620 in the disassembly and assembly channel, leaving more operating space for the staff to build the first or second winding structure. At the same time, it can also ensure that the battery pack 610 can accurately reach the top of the support frame 400 for hoisting.

[0043] Specifically, the support bracket 500 includes a first arm and a second arm. The first end of the first arm is connected to the left side of the support frame 100, and the first end of the second arm is connected to the right side of the support frame 100. The tail ends of the first arm and the second arm are connected to form a triangle with the support frame 100, and the first hook 170 is provided at the tail ends of the first arm and the second arm.

[0044] In some embodiments of the present invention, the first connection structure 110 includes a horizontal bracket 120, a first binding module 141, and a second binding module 142. The horizontal bracket 120 is disposed above or below the battery storage compartment 620. Both sides of the horizontal bracket 120 are connected to the support frame 100 via upright members 160. Both sides of the horizontal bracket 120 are provided with locking members 130. The locking members 130 are used to allow the two sides of the horizontal bracket 120 to be detachably connected to the upright frames 630 on both sides of the energy storage compartment frame 600 on the battery storage compartment 620. The first binding module 141 and the second binding module 142 are respectively used to be detachably bound to the upright frames 630 and the upright members 160 on the left and right sides.

[0045] Both sides of the horizontal bracket 120 are connected to the support frame 100 via upright members 160 to ensure stable connection on both sides of the support frame 100. Then, the locking member 130 connects the two sides of the horizontal bracket 120 to the upright members 630 on both sides of the battery compartment 620, forming a basic fixed structure. Since the support frame 100 is suspended below, to further improve the stability of the connection, the first binding module 141 is located on the left side of the battery compartment 620 and bound to the upright members 630 and 160 on the left side. The second binding module 142 is located on the right side of the battery compartment 620 and bound to the upright members 630 and 160 on the right side. Through the binding structure and the locking member 130, the upright members 630 and 160 are subjected to multiple points of force from the height direction, thereby making the connection structure more stable and reliable.

[0046] In some embodiments of the present invention, the locking member 130 includes a first connecting hole 131 and a first bolt 132 disposed on the horizontal bracket 120. The first connecting hole 131 can correspond to a second connecting hole on the upright frame 630. The first bolt 132 passes through the first connecting hole 131 and the second connecting hole. It can be understood that the second connecting hole is disposed on the side of the upright frame 630 close to the support frame 100. The detachable connection of the first bolt 132 and the first connecting hole 131 and the second connecting hole makes disassembly and installation simple and convenient, and easy to operate.

[0047] The first binding module 141 and the second binding module 142 work together to apply force to the side of the upright frame 630 away from the support frame 100, so that the upright frame 630 and the upright member 160 are bound together, and the structure is firm and stable.

[0048] Specifically, both the first binding module 141 and the second binding module 142 include multiple binding components 150. Each binding component 150 includes an arc-shaped pull rod 151 and a fixing plate 152. The pull rod 151 is wound around the outer periphery of the upright frame 630 and the upright member 160. The fixing plate 152 is provided with two through holes 153. Both ends of the pull rod 151 are provided with external threads. The two ends of the pull rod 151 are correspondingly inserted into the through holes 153 and connected to the locking nut 154 through the external threads.

[0049] There can be multiple binding components 150 on both the left and right sides. Multiple binding components 150 are arranged along the height direction of the upright member 160. The tie rod 151 is wrapped around the outer periphery of the upright frame 630 and the upright member 160. Then, the tie rod 151 is inserted into the through hole 153 one by one and locked by the locking nut 154. As the locking nut 154 rotates, the space enclosed by the inner wall of the tie rod 151 and the fixing plate 152 gradually shrinks, so that it can be tightly bound to the outer periphery of the upright frame 630 and the upright member 160. The upright frame 630 and the upright member 160 are not easy to separate. Furthermore, the friction between the inner wall of the tie rod 151 and the wall of the fixing plate 152 and the outer periphery of the upright frame 630 and the upright member 160 is used to reduce the bearing force of the locking member 130.

[0050] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
