Description

Technical Field

[0001] This utility model relates to the field of battery loading, unloading and transportation technology, and specifically to an auxiliary replacement platform for battery PACK in an energy storage power station. Background Technology

[0002] Battery removal and installation devices are a common type of auxiliary equipment that saves battery transportation time, improves work efficiency, and reduces labor costs. Current battery removal and installation devices primarily use forklifts. The forklift is moved under the battery, the front of the forklift is slowly raised to load and unload the battery, then it is reset, and finally the battery is moved onto a transport vehicle.

[0003] However, current battery installation and removal technology in China is mainly manual and semi-automatic. The equipment currently used relies heavily on manual operation, which not only leads to low overall efficiency but also compromises safety. In particular, battery installation and removal operations are entirely manual, requiring scaffolding to assist when batteries are positioned high. This method of work is space-consuming and time-consuming. Furthermore, the lack of clamping and protection devices makes it easy to damage batteries during operation, increasing production costs. Additionally, the non-adjustable height of the battery installation and removal platform further exacerbates the difficulty of the operation.

[0004] However, the aforementioned battery installation and removal device, primarily based on a forklift, still provides certain conveniences during operation, especially since the forklift's front end can transport the lifting platform to the battery level. To further improve the convenience and stability of loading and unloading, reduce labor costs, and ensure battery safety during handling, this application proposes the design of a fully automated battery pack replacement platform. This platform eliminates the need for scaffolding and allows the entire device to perform multiple functions, including ground travel, flexible control, automatic lifting, clamping and pushing, and assisted loading and unloading. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application proposes a PACK-assisted replacement platform for batteries in energy storage power stations. This platform offers significant advantages such as automated control, solving the problem of inconvenience in using traditional battery disassembly and assembly devices.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A battery pack replacement auxiliary platform for an energy storage power station is disclosed. The platform is mounted on a forklift with a certain load-bearing capacity. The front end of the forklift has a lifting function, which can transport the replacement platform to a position where loading and unloading can be carried out. The platform has an auxiliary pushing device for battery packs, a platform height adjustment device, and a clamping device to ensure the safe transport of battery packs.

[0008] The forklift's front end consists of a fork carriage, forks, a backrest, a mast, and a lifting chain. It has a certain load-bearing capacity and needs to withstand the weight of the PACK auxiliary changing platform and the loading and unloading of batteries. The PACK auxiliary changing platform is mounted on the forks by welding or bolting.

[0009] Furthermore, the PACK-assisted replacement platform is moved to different heights by the front of the forklift, enabling the loading and unloading of batteries located at different heights.

[0010] The auxiliary pushing device consists of a push plate, a vertical plate, a sliding plate, a sliding guide rail, a ball screw, a coupling, and a motor. The motor drives the entire auxiliary pushing device, saving manpower and time during loading and unloading, and it still exhibits excellent pushing performance even with heavier batteries.

[0011] Furthermore, the push plate and the vertical plate, and the vertical plate and the sliding plate are connected and fixed to each other by bolts arranged symmetrically on both sides, so as to achieve average force distribution and make it less likely for components to loosen even when pushing heavier batteries or operating for a long time.

[0012] Furthermore, the front end of the push plate can be equipped with a hook, which can be connected to the end ring of the battery through the hook. Combined with the motor control system, the push plate can move forward and backward, thereby driving the battery to complete the disassembly operation.

[0013] Furthermore, the auxiliary push platform also needs to be designed with fixed guardrails at both ends to limit the battery during the push process and prevent the battery from slipping and being damaged.

[0014] Furthermore, the push platform is equipped with drive rollers to reduce the friction when pushing or pulling the battery, thereby increasing the maximum weight that can be pulled.

[0015] The above-mentioned auxiliary pushing device design can achieve safe auxiliary pushing of batteries of different qualities.

[0016] The platform height adjustment device consists of a motor and a lifting mechanism. It can change the relative height between the battery and the platform, and adjust the angle of the battery to facilitate battery installation and removal.

[0017] Furthermore, the entire system has four sets of battery angle adjustment devices, symmetrically distributed along the center, which can meet the requirements of the angle of different batteries during battery installation and removal.

[0018] Furthermore, the elevator and the push platform are rigidly connected by bolts to ensure that the battery will not have any accidents during the lifting or lowering process.

[0019] The aforementioned platform height adjustment device can meet the angle requirements during battery loading and unloading.

[0020] The clamping device consists of a clamping plate, a clamping vertical plate, a clamping sliding plate, a guide rail, a ball screw, a coupling, and a motor. The energy transmitted from the motor drives the fixed push plate to move.

[0021] Furthermore, the clamping device consists of two sets, installed symmetrically on the left and right sides. The battery is clamped by clamping plates that move from both sides, ensuring battery safety.

[0022] Furthermore, the clamping plate structure has a flexible design that can adapt to the appearance of batteries with different shapes, ensuring that the clamping force is evenly distributed.

[0023] Furthermore, the surface of the clamping plate can be coated with an anti-slip texture to increase friction with the battery and prevent slippage.

[0024] The above-mentioned clamping device can achieve automatic clamping and release of the battery.

[0025] The battery pack auxiliary replacement platform features a lightweight design, with a hollow support frame to reduce weight and further facilitate the transportation and handling of heavier batteries.

[0026] Compared with existing technologies, the technical solution in this application presents the following beneficial effects:

[0027] 1. This new type of energy storage power station battery PACK auxiliary replacement platform has an automatic lifting function, which can automatically raise the battery to the same plane as the battery pack.

[0028] 2. It also has an auxiliary pushing device, which can save manpower. When loading and unloading batteries, staff do not need to manually push the batteries, which brings great convenience.

[0029] 3. The platform is also equipped with four sets of automatic battery angle adjustment devices, which can adjust the height and angle of the battery during installation and disassembly, further adapting to the complex loading and unloading environment of the battery.

[0030] 4. The platform also has clamping devices installed symmetrically on both sides, which can clamp and limit the battery during loading and unloading, ensuring the correct movement trajectory of the battery and guaranteeing the safety of the battery throughout the entire loading and unloading process.

[0039] The technical solution of the battery PACK assisted replacement platform of this application will be described in detail and completely below with reference to the accompanying drawings. The implementation method of this application can be clearly understood by referring to the accompanying drawings.

[0040] refer to Figure 1 The battery outer packaging box 1 contains layers of batteries 3, which are stacked on battery support bases 4, filling the entire inner packaging box 2. When the batteries are in a high position, scaffolding 5 needs to be erected manually so that workers 6 can load and unload the batteries, which causes a lot of inconvenience.

[0041] See Figure 2 This application pertains to a fully automated auxiliary replacement platform for a battery pack in an energy storage power station. It is designed based on a forklift head 7, whose forklift front end 8 provides lifting functionality, and is also bolted to the platform support frame 14.

[0042] When loading or unloading batteries, the operator drives the forklift head 7 to transport the entire platform to the bottom of the battery installation box. The automatic lifting system receives a signal from the height sensor 15 and controls the lifting via the front end 8 of the forklift, continuously adjusting the position of the platform support frame 14 until it is on the same plane as the battery 3.

[0043] See Figure 1 The guide rail 10 is located at the exact center of the platform support frame 14. Inside the guide rail 10 is a ball screw mechanism, which is connected to the drive motor via a coupling to obtain power. (Reference) Figure 2 The ball screw is connected to the sliding plate 17 by bolts, and the sliding plate 17 is connected to the vertical plate 16 by bolts. The vertical plate 16 and the push plate 11 are also fixed together by bolts. The limiting plate 18 serves to limit the movement of the battery during loading and unloading, protecting the battery's safety.

[0044] During the battery loading and unloading process, the ball screw mechanism inside the guide rail 10 receives power from the motor, converting the rotational motion into linear motion, thereby driving the sliding plate 17 to move within the guide rail track. The vertical plate 16 and the push plate 11 are directly or indirectly fixed to the sliding plate 17 and also perform linear motion, thus the push plate 5 pushes the battery to complete the auxiliary work.

[0045] The platform rollers 9 are numerous, and their number can be determined according to the actual size of the platform. They are fixed to both sides of the platform by welding or integrated technology, which helps to reduce friction during battery movement.

[0046] In addition, the push plate 11 can be equipped with two or more hooks to help pull the battery.

[0047] See Figure 3 The push motor 12 generates power to drive the lifting platform 13 to complete the lifting and lowering of a portion of the platform. The lifting platform 13 also has a ball screw mechanism inside, which converts the rotational motion of the push motor 12 into linear motion of the platform height.

[0048] See Figure 1 The push motor 19, the lifting mechanism 20, and the position sensor 21 are arranged in four sets, symmetrically installed at the front and rear of the platform, which can meet the angle requirements of different working conditions for battery installation or removal. When installing the battery, the two sets closer to the forklift head 7 work to raise the battery position angle on that side, making it easier for the battery to enter the mounting cabinet; when removing the battery, the two sets farther away from the forklift head 7 work to raise the battery position angle on that side, making it easier for the battery to enter the replacement platform.

[0049] See Figure 4The clamping guide rails 13 are installed on both sides of the platform support frame 14, and the internal mechanism of the clamping guide rails 13 is also a ball screw mechanism. During the assisted loading and unloading of the battery, the moving nut 24 inside the ball screw of the clamping guide rail 13 moves linearly. Since the clamping vertical plate 22, the clamping sliding plate 23 and the clamping plate 12 are directly or indirectly fixed to the moving nut 24 by bolts, they also move linearly. The clamping plates 12 on both sides move towards the battery in the middle, and finally complete the clamping work, ensuring the safety of the battery during the assisted loading and unloading process.

[0050] The working principle of the auxiliary replacement platform for the battery pack of the aforementioned energy storage power station is as follows:

[0051] During battery replacement and unloading, firstly, worker 6 drives the forklift head 7 to directly in front of and below the battery outer casing 1. Then, the automatic battery position lifting system controls the forklift front section 8 to rise, receiving a signal from the height sensor 15, and continuously adjusts the position of the battery 3 until it is level with the battery casing position. The control block diagram of the entire lifting control system is as follows: Figure 6 As shown, let the height of the battery be... The battery to be installed is located in the packaging box. The system's objective function for controlling the battery height using PID control is shown below:

[0052] .

[0053] Next, the motor of the auxiliary drive device starts running, and the ball screw in the guide rail 10 begins to move, driving the vertical plate 16 and the push plate 11 to move linearly. The push plate 11 directly contacts the battery, performing an auxiliary pushing action on the battery. At the same time, the ball screws in the clamping guide rails 13 on both sides start working, driving the clamping vertical plate 22, the clamping sliding plate 23, and the clamping plate 12 to move. The clamping plates 12 on both sides move inward to clamp the battery, preventing side slippage during battery installation and removal that could damage the battery.

[0054] During battery movement, the automatic battery angle adjustment system activates. Receiving battery height information from four position sensors, the system controls four push motors 12 at different positions to continuously adjust the battery's angle for easier loading and unloading. Using the driver's position as a reference, let the height position of the left front end of the motor be... The height position of the front right end is The height position of the rear left end is The height position of the rear right end is The battery tilt position is controlled using PID control. When the battery needs to tilt left or right, the objective function is... When the battery needs to be tilted forward or backward, the objective function is: The specific control objective function is shown below:

[0055] ;

[0056] .

[0057] Thus, the objective of this utility model has been achieved.

[0058] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
