Description

Technical Field

[0001] The utility model relates to the technical field of battery installation, and more specifically, to a battery pack installation tray. Background Art

[0002] Energy storage batteries primarily refer to batteries used in solar and wind power generation equipment, as well as for storing renewable energy. To meet the demand for efficient, flexible, and reliable energy storage solutions in modern power systems and across multiple sectors, products such as energy storage cabinets and containers are being continuously introduced. Currently, mainstream energy storage cabinets and containers utilize battery packs as energy storage units, increasing their energy capacity by stacking battery packs.

[0003] As the core unit of energy storage, the efficiency and safety of the installation and disassembly process of the energy storage battery pack are directly related to the performance and reliability of the entire energy storage system. Currently, the mainstream installation and disassembly method is to use a forklift to transport the battery pack directly on a wooden pallet for transportation, installation and disassembly. By adjusting the position of the forklift, the battery pack is moved to the corresponding installation position of the battery cluster rack and installed on the cluster rack. This method is simple to operate, but its limitations are becoming increasingly prominent in the face of complex and changing construction environments. Due to the limited adjustment accuracy of the forklift and the small space of the cluster rack, the battery pack cannot be aligned with the cluster rack installation position during the installation process and cannot be installed normally. The forklift position needs to be repeatedly adjusted to complete the installation. The adjustment process is complicated and slow. During this process, the battery pack may be squeezed, deformed and damaged due to misalignment with the cluster rack due to improper operation.

[0037] (Example)

[0038] This embodiment provides a universal battery pack mounting tray that can adapt to various environments and improve installation and disassembly accuracy and efficiency.

[0039] See Figure 1 and Figure 2 This embodiment includes a scissor-type lifting mechanism 1, which also includes an upper supporting surface 12, a lower supporting surface 13 and two parallel scissor arm assemblies 14.

[0040] The upper support surface 12 and the lower support surface 13 are symmetrically provided with two horizontally arranged slides and two rotation axes. Each scissor arm assembly 14 includes a first arm 141 and a second arm 142 arranged crosswise. The first arm 141 and the second arm 142 intersect in the middle to form a central hinge point and can rotate around the central hinge point. The lower ends of the two first arms 141 are respectively rotatably connected to the rotation axis of the lower support surface 13, and the upper ends are respectively slidably connected to the slides of the upper support surface 12. The lower ends of the two second arms 142 are respectively slidably connected to the slides of the lower support surface 13, and the upper ends are rotatably connected to the rotation axis of the upper support surface 12. A first connecting shaft 143 is provided between the two central hinge points. The scissor-type lifting mechanism has a simple and stable structure, can be easily lifted and lowered, is low-cost, and is easy to maintain.

[0041] The scissor-type lifting mechanism 1 also includes a second connecting shaft 144 arranged parallel to the first connecting shaft 143, and the second connecting shaft 144 is hinged to the first arm 141 and the second arm 142 respectively; the drive assembly 11 is fixedly connected to the second connecting shaft 144. The drive assembly 11 uses a hydraulic lifting ram, one end of which is fixed to the lower support surface 13, and the output end is fixed to the second connecting shaft 144. The lower support surface 13 is also provided with a first switch 15 for controlling the raising and lowering of the hydraulic lifting ram. By driving the second connecting shaft by the drive assembly, the drive assembly can simultaneously control the raising and lowering of the two scissor arm assemblies. By setting a switch to control the raising and lowering of the hydraulic lifting ram, it is convenient to fine-tune the height of the pallet.

[0042] A forklift tine fixing rail 2 is fixed below the lower support surface 13 of the scissor-type lifting mechanism 1. Shock-absorbing strips are installed inside the forklift tine fixing rail 2. The rubber shock-absorbing strips inside the forklift tine fixing rail can reduce the impact of vibration on the battery pack during transportation. Conventional pallets do not have a shock-absorbing design.

[0043] This embodiment further includes a screw adjustment mechanism 3 fixed above the upper support surface 12 of the scissor-type lifting mechanism 1 and a tray 4 fixed above the screw adjustment mechanism 3. The tray 4 is provided with a guide rail that cooperates with the battery pack.

[0044] The screw adjustment mechanism 3 includes a screw mounting block 31 and a screw 32 that is rotatably mounted on the screw mounting block 31. The screw mounting blocks 31 are provided in two groups, symmetrically arranged on the front and rear sides of the upper support surface 12, with each group comprising two screw mounting blocks 31. The screws 32 are provided with two parallel threaded through-holes, each of which is mating with the other, extending through a set of screw mounting blocks 31. The screws 32 are axially arranged horizontally in the left-right direction. A mating nut 33 is provided on one of the screws 32, which is fixedly connected to the tray 4 at its top. A rotating handle 35 is provided at one end of the screw 32. The screw mounting block 31 is also provided with a support roller 34 that mates with the tray 4. The screw adjustment mechanism enables horizontal left-right movement of the tray. The provision of the support roller makes the tray's movement smoother, and the screw adjustment mechanism is more labor-saving. The provision of the rotating handle facilitates control of the tray's horizontal left-right movement.

[0045] Furthermore, the first switch 15 and the rotating handle 35 are replaced with brushless servo motor drives, and a wireless control system is used to achieve separation of human and equipment operation, thereby improving the safety of operators at the installation site.

[0046] In this embodiment, the installation tray is changed from a fixed tray to a movable tray. The battery pack placed on the tray uses a lifting mechanism and a screw adjustment mechanism to adjust the relative position of the battery pack and the cluster frame, making the installation and removal of the battery pack more convenient, reducing the risk of deformation and damage during the installation and removal of the battery pack and the repair rate, and improving system safety.

[0047] In this embodiment, the battery pack mounting pallet is fixed to the fork tines of the forklift. The battery pack is placed stably on the pallet rail and fixed with the fixed rail. According to the cluster rack layout, first use a forklift to move the device and the battery pack to the vicinity of the installation position. Press the first switch 15 to make fine adjustments in the vertical (up and down) direction, and rotate the handle 35 to make fine adjustments in the horizontal (left and right) direction, so that the pallet and the battery pack are accurately moved along the preset path to the vicinity of the installation position, ensuring that the battery pack is accurately docked with the cluster rack. After the battery pack is docked with the cluster rack, the battery pack is firmly fixed to the cluster rack. After the battery pack is fixed to the cluster rack, operate the forklift to separate the pallet from the battery pack and evacuate to a safe area to prepare for the next installation operation.

[0048] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
