Description

Technical Field

[0001] This invention relates to the field of installation and operation and maintenance technology of electrochemical energy storage systems, and in particular to the operation and maintenance tooling of independently electrically controlled split-type battery packs. Background Technology

[0002] In current energy storage power stations, data centers, and industrial and commercial scenarios, the installation and maintenance of battery packs often rely on integrated modified forklift fixtures for loading, unloading, and alignment. These fixtures are mainly constructed by adding a load-bearing platform, guide rails, and hand-cranked or electric fine-tuning mechanisms to the forklift forks or mast. During operation, the fixture draws power directly from the forklift's power system to drive the sensors and actuators. Simultaneously, it utilizes limit blocks, rollers, or ball bearing structures on the platform to reduce frictional resistance during battery pack pushing.

[0003] However, existing integrated forklift tooling has significant drawbacks: its alignment adjustment relies solely on the pitch and lift movements of the forklift forks, making it impossible to perform high-precision independent fine-tuning of yaw, pitch, and roll angles. This results in severely insufficient adjustment freedom and alignment accuracy. When tolerances for the rack rails, positioning holes, and terminal connectors are tight, the rack housing is easily scratched, connectors are damaged, and safety hazards may even arise. Furthermore, the tooling's power supply is directly drawn from the forklift's power source, leading to complex power connection issues, difficulty in controlling electromagnetic interference, and potential impacts on the vehicle and forklift's original factory warranty and on-site safety compliance assessments. Summary of the Invention

[0004] This invention provides a separate battery pack maintenance fixture with independent electronic control, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A modular battery pack maintenance tool with independent electronic control includes a base platform, an adjustment platform, and a load platform stacked sequentially from bottom to top. The base platform is provided with fork slots for forklift insertion, and the load platform is used to support the battery pack. Four sets of lifting components are installed at the four corners between the base platform and the adjustment platform. The four sets of lifting components are used to drive the adjustment platform to make fine adjustments to the pitch and yaw angles relative to the base platform. A rotary assembly is provided between the adjustment platform and the load platform to drive the load platform to yaw left and right relative to the adjustment platform around the vertical rotation axis. An independent electrical control system is provided on the base platform. The independent electrical control system includes a battery box and an electrical control box. The battery box and the electrical control box are electrically connected and are used to provide independent power and motion control for the lifting assembly and the slewing assembly.

[0006] Furthermore, a locking assembly, including a longitudinal foot cup and a transverse foot cup, is also provided on the fork tooth groove; The longitudinal foot cup is adjustable along the height direction of the forklift fork, and the transverse foot cup is adjustable along the width direction of the forklift fork, which is used to form a bidirectional rigid lock between the base platform and the forklift fork.

[0007] Furthermore, the fixed end of each lifting component is connected to the base platform, and the driving end is connected to the adjustment platform; The differential extension and retraction of the four sets of lifting components are used to independently fine-tune the pitch and yaw angles of the adjustment platform relative to the base platform.

[0008] Furthermore, the rotary assembly includes a rotary bearing and a drive component; The inner ring of the slewing bearing is fixedly connected to the adjustment platform, and the outer ring of the slewing bearing is fixedly connected to the load platform. The drive component is connected to the outer ring of the slewing bearing for driving the outer ring to rotate, thereby causing the load platform to yaw left and right relative to the adjustment platform.

[0009] Furthermore, a load-bearing structure is provided on the upper surface of the load platform; The load-bearing structure is one of a roller, a ball bearing array, or a low-friction plate.

[0010] Furthermore, the load platform is also equipped with a limiting guide component; The limiting and guiding assembly includes lateral guide plates disposed on both sides of the load platform along the battery PACK pushing direction, and a guide block disposed at the end of the lateral guide plates. The guide block is used to guide the battery pack in, and ball bearings are provided on the opposite surfaces of the two lateral guide plates to constrain the pushing path of the battery pack.

[0011] Furthermore, the battery box is a 24V, 36V, or 48V DC rechargeable battery pack, and the electrical control box is equipped with a DC / DC conversion module, which is used to convert the battery box voltage into a control power supply voltage.

[0012] Furthermore, the load platform is also equipped with a material pushing component; The pushing assembly includes a pushing platform and spring columns disposed on both sides of the pushing platform; The material pushing platform is driven by a first linear drive mechanism to achieve reciprocating pushing motion on the load platform; The spring post is mounted on the pushing platform via a second linear drive mechanism to adjust the initial installation position of the spring post on the pushing platform.

[0013] Furthermore, the independent electronic control system also includes one or more of the following: an emergency stop button, a travel limit switch, an overcurrent protection unit, an overtemperature protection unit, and a voltage detection unit.

[0014] Furthermore, the independent electronic control system is also equipped with a foot cup locking detection sensor; The foot cup locking detection sensor is electrically connected to the electrical control box and is respectively set for the longitudinal foot cup and the transverse foot cup, and is used to accurately detect the locking status of the longitudinal foot cup and the transverse foot cup.

[0015] The technical solution of this invention can achieve the following technical effects: This invention achieves pitch and yaw fine-tuning through a four-corner lifting assembly, and achieves left and right yaw fine-tuning in conjunction with a slewing assembly. It can meet the high-precision alignment requirements of battery packs, frame rails, and battery clusters, effectively avoiding scratches on the battery pack casing and significantly improving maintenance efficiency. The tooling adopts an independent electrical control system with its own battery box and electrical control box, eliminating the need to draw power from the forklift, avoiding issues such as forklift circuit modification, electromagnetic interference, and expiration of original factory warranty, thus improving on-site operation safety and compliance.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] like Figures 1-7 As shown, this application provides an independently electrically controlled split battery PACK maintenance tool, including a base platform 1, an adjustment platform 2 and a load platform 3 stacked sequentially from bottom to top; The base platform 1 is provided with fork tooth grooves 4 for forklifts to insert into, and the load platform 3 is used to support the battery PACK. Four sets of lifting components 5 are installed at the four corners between the base platform 1 and the adjustment platform 2. The four sets of lifting components 5 are used to drive the adjustment platform 2 to make fine adjustments to the pitch and yaw angles relative to the base platform 1. A rotary assembly 6 is provided between the adjustment platform 2 and the load platform 3, which is used to drive the load platform 3 to yaw left and right relative to the adjustment platform 2 around the vertical rotation axis. An independent electrical control system is installed on the base platform 1. The independent electrical control system includes a battery box 7 and an electrical control box 8. The battery box 7 and the electrical control box 8 are electrically connected and are used to provide independent power and motion control for the lifting assembly 5 and the slewing assembly 6.

[0022] In this embodiment, the base platform 1, adjustment platform 2, and load platform 3 form an overall steel frame structure. Two sets of fork slots 4 are provided at the bottom of the base platform 1. These slots are either through slots or blind slots, and their shape matches the cross-section of a standard industrial forklift fork, allowing the forklift to directly insert and lift and move the entire tooling. Lifting components 5 are vertically fixed at the four corners of the upper surface of the base platform 1. The output ends of the lifting components 5 are connected to and support the adjustment platform 2. By independently controlling the extension and retraction strokes of the four corner lifting components 5, the adjustment platform 2 can be driven to tilt relative to the base platform 1, thereby achieving high-precision fine-tuning of the pitch and yaw angles. The rotating component 6 is set at the center of the upper surface of the adjustment platform 2. The lower end of the rotating component 6 is fixed on the adjustment platform 2, and the upper end is connected to the load platform 3. The load platform 3 is located at the top layer and is used to directly support the battery PACK. Under the control command, the rotating component 6 can drive the load platform 3 to yaw left and right around the rotation axis by a limited angle, thereby adjusting the orientation of the battery PACK. An independent electric control system is fixedly installed on the base platform 1. The independent electric control system includes a battery box 7 and an electric control box 8. The battery box 7 has a built-in DC battery pack to provide power to the lifting assembly 5 and the slewing assembly 6. The electric control box 8 is equipped with a main control unit, a driver and a safety protection unit, which are used to output control commands and realize safety interlocks such as overload, limit, and emergency stop. The entire independent electric control system is completely isolated from the forklift's electrical system.

[0023] Specifically, during operation, the forklift forks are inserted into the fork slots 4 of the base platform 1, moving the tooling to the battery PACK position, so that the battery PACK is supported on the load platform 3; the independent electronic control system performs a self-test upon power-up, without needing to be connected to the forklift power supply; the forklift moves the tooling and battery PACK together to the front of the battery rack to complete rough alignment; the lifting component 5 achieves high-precision leveling of pitch / yaw; the slewing component 6 achieves precise correction of the left and right yaw angles, combined with laser line-assisted alignment; after alignment is completed, the battery PACK is pushed into the rack, and the tooling is removed.

[0024] The four-corner lifting components 5 enable pitch and yaw fine-tuning, while the slewing components 6 enable left and right yaw fine-tuning. This meets the high-precision alignment requirements of the battery pack, frame rails, and battery clusters, effectively preventing scratches on the battery pack casing and improving maintenance efficiency. The tooling uses an independent electrical control system with its own battery box 7 and electrical control box 8, eliminating the need to draw power from the forklift. This avoids issues such as forklift circuit modification, electromagnetic interference, and the expiration of the original factory warranty, thus improving on-site operation safety and compliance.

[0025] In a preferred embodiment, a locking assembly is also provided on the fork tooth groove 4, including a longitudinal foot cup 9 and a transverse foot cup 10; the longitudinal foot cup 9 is adjustable along the height direction of the forklift fork, and the transverse foot cup 10 is adjustable along the width direction of the forklift fork, which is used to form a bidirectional rigid locking between the base platform 1 and the forklift fork.

[0026] The internal installation space of the fork slot 4 can be adjusted longitudinally and laterally, and it is compatible with forklift forks of different cross sections and spacings. No customization or modification is required, and it has strong cross-model versatility. It can be used directly after inserting the forks and locking them, which greatly shortens the on-site clamping time and improves operation and maintenance efficiency.

[0027] In this invention, the fixed end of each lifting component 5 is connected to the base platform 1, and the driving end is connected to the adjustment platform 2; through the differential extension and retraction of the four lifting components 5, the pitch angle and yaw angle of the adjustment platform 2 relative to the base platform 1 are independently fine-tuned.

[0028] Each lifting assembly 5 is independently controlled or grouped by an independent electronic control system. Specific control methods include: when the extension strokes of the two lifting assemblies 5 on the front side and the two lifting assemblies 5 on the rear side are different, the pitch angle of the tooling can be finely adjusted by tilting forward / backward; when the extension strokes of the two lifting assemblies 5 on the left side and the two lifting assemblies 5 on the right side are different, the yaw angle of the tooling can be finely adjusted by tilting left / right; at the same time, by controlling the stroke difference between diagonal or adjacent lifting assemblies 5, the pitch and yaw can be linked and adjusted to quickly correct the parallelism and levelness deviations between the battery PACK and the battery rack guide rail, and complete the precise adjustment of the composite attitude.

[0029] The four-corner travel difference allows for continuous micro-angle adjustment, precisely matching the tolerance requirements of the battery pack, rack rails, and battery clusters, effectively preventing scratches on the battery pack casing and significantly improving maintenance efficiency. This fixture allows for flexible switching between single-group adjustment, pairwise group adjustment, and four-group synchronous adjustment, combining coarse and fine adjustments to quickly adjust the battery pack to the docking position, significantly shortening alignment time. Preferably, the lifting component 5 is one of an electric screw actuator, an electric cylinder, or a ball screw jack.

[0030] In a preferred embodiment, the rotary assembly 6 includes a rotary bearing 61 and a drive component 62; the inner ring of the rotary bearing 61 is fixedly connected to the adjustment platform 2, and the outer ring of the rotary bearing 61 is fixedly connected to the load platform 3. The drive component 62 is connected to the outer ring of the slewing bearing 61 for driving the outer ring to rotate, thereby causing the load platform 3 to yaw left and right relative to the adjustment platform 2.

[0031] Specifically, the drive component 62 is a rack and pinion drive, and the outer ring of the slewing bearing 61 has teeth that mesh with the rack in the circumferential direction. The rack can achieve linear transmission through direct or indirect drive. In addition, the drive component 62 can also adopt a worm gear mechanism, a harmonic reducer, or a direct drive motor, including but not limited to the above-mentioned transmission forms.

[0032] In this invention, a bearing structure 11 is provided on the upper surface of the load platform 3; the bearing structure 11 is one of a roller, a ball bearing array, or a low-friction plate. By utilizing the low-friction bearing structure 11, the frictional resistance during the pushing and pulling of the battery PACK can be reduced, making the pushing process smooth and without jamming. Combined with angle fine-tuning, precise docking can be achieved, improving the first-time placement rate.

[0033] In a preferred embodiment of the present invention, the load platform 3 is further provided with a limiting guide assembly 12; the limiting guide assembly 12 includes lateral guide plates 121 disposed on both sides of the load platform 3 along the battery PACK pushing direction, and a guide block 122 disposed at the end of the lateral guide plate 122. The guide block 122 is used to guide the battery pack in and achieve coarse alignment. Ball bearings are provided on the opposite surfaces of the two side guide plates 121 to constrain the pushing path of the battery pack and ensure that the battery pack maintains a consistent path when pushed in / pulled out, without deviating or scratching the rack guide rail. The guide block 122 precisely limits the position to avoid over-pushing or slipping.

[0034] In this invention, the battery box 7 is a 24V, 36V or 48V DC rechargeable battery pack, and the electrical control box 8 is equipped with a DC / DC conversion module, which is used to convert the voltage of the battery box 7 into the control power supply voltage.

[0035] The tooling has its own rechargeable battery pack, eliminating the need to draw power from the forklift and completely decoupling it from the forklift's electrical system, thus avoiding modification and electromagnetic interference issues. The DC / DC module converts the high-voltage power battery voltage into a stable low-voltage control voltage, ensuring reliable operation of the control system and actuators.

[0036] In a preferred embodiment of the present invention, a pushing assembly 13 is further provided on the load platform 3; the pushing assembly 13 includes a pushing platform 131 and spring columns 132 disposed on both sides of the pushing platform 131; the pushing platform 131 is driven by a first linear drive mechanism 133 to realize reciprocating pushing motion on the load platform 3; the spring columns 132 are installed on the pushing platform 131 by a second linear drive mechanism 134 to adjust the initial installation position of the spring columns 132 on the pushing platform 131.

[0037] The battery box 7 is electrically connected to the control box 8, providing independent power and motion control for the first linear drive structure 133 and the second linear drive mechanism 134 of the feeding assembly 13. The driving directions of the first linear drive mechanism 133 and the second linear drive mechanism 134 are parallel, and a screw and nut mechanism or a synchronous belt drive can be selected. Two sets of spring columns 132 are symmetrically arranged on both sides of the feeding platform 131. The spring columns 132 have a telescopic elastic function and can extend and retract along their own axis, which can provide elastic limit and buffer for the battery PACK.

[0038] During operation, the second linear drive mechanism 134 first adjusts the spring columns 132 on both sides to a suitable initial installation position, matching the length and pushing stroke of the battery pack to be transported; then the first linear drive mechanism 133 is activated, driving the pushing platform 131 and the battery pack to reciprocate along the load platform 3, achieving precise pushing and docking of the battery pack with the battery rack; during the pushing process, if there is a slight deviation between the battery pack and the rack, the spring columns 132 can achieve elastic buffering through their own extension and retraction, avoiding scratches on the battery pack casing or damage to components caused by hard contact, while also playing a centering role, ensuring that the battery pack is always pushed along the preset path.

[0039] In a preferred embodiment of the present invention, the independent electronic control system further includes one or more of the following: an emergency stop button, a travel limit switch, an overcurrent protection unit, an overtemperature protection unit, and a voltage detection unit.

[0040] The electrical control box 8 is configured to immediately disable the operation of the lifting assembly 5 and the slewing assembly 6 when any abnormal state is detected, thereby achieving safety interlock protection.

[0041] In this invention, the independent electronic control system is also equipped with a foot cup locking detection sensor; the foot cup locking detection sensor is electrically connected to the electronic control box 8 and is respectively set for the longitudinal foot cup 9 and the transverse foot cup 10, for accurately detecting the locking status of the longitudinal foot cup 9 and the transverse foot cup 10.

[0042] The electrical control box 8 is configured to allow the lifting assembly 5 and the slewing assembly 6 to start only after the longitudinal foot cup 9 and the transverse foot cup 10 are detected to be locked in place.

[0043] Specifically, the foot cup locking detection sensor can be a contact type stroke sensor or a proximity type sensor. The sensor corresponding to the longitudinal foot cup 9 is installed on the locking execution end of the longitudinal foot cup 9, and the sensor corresponding to the transverse foot cup 10 is installed on the locking execution end of the transverse foot cup 10. The locking stroke signals of the longitudinal foot cup 9 along the height direction of the forklift fork and the transverse foot cup 10 along the width direction of the forklift fork are collected in real time, and the collected signals are transmitted to the electrical control box 8 in real time.

[0044] During operation, the operator first inserts the forklift forks into the fork slots 4 of the base platform 1, and then adjusts the longitudinal foot cups 9 and the transverse foot cups 10 respectively, so that the longitudinal foot cups 9 clamp the forklift forks in the height direction and the transverse foot cups 10 clamp the forklift forks in the width direction, completing the bidirectional rigid locking. When both the longitudinal foot cups 9 and the transverse foot cups 10 are locked in place, the corresponding detection sensors are triggered and send a transverse locking signal to the electrical control box 8, which releases the start restriction on the lifting assembly 5 and the slewing assembly 6, allowing the operator to control the lifting assembly 5 to make fine adjustments to the pitch and yaw angles through the electrical control system, and control the slewing assembly 6 to drive the load platform 3 to yaw left and right.

[0045] If the control box 8 receives a locking signal from only one set of foot cups, or receives no locking signal from any set of foot cups, it is determined that the locking is not up to standard. In this case, the control box 8 will prohibit the lifting assembly 5 and the slewing assembly 6 from starting. At the same time, it can trigger warning prompts as needed, such as flashing indicator lights and buzzer alarms, to remind the operator to check the locking status of the longitudinal foot cup 9 and the transverse foot cup 10. Normal operation can only be started after both are locked in place.

[0046] Although this application has been described in conjunction with specific features and embodiments, it is obvious that various modifications and combinations can be made thereto without departing from the spirit and scope of this application. Accordingly, this specification and drawings are merely exemplary illustrations of the application as defined herein, and are to be considered as covering any and all modifications, variations, combinations, or equivalents within the scope of this application. Clearly, those skilled in the art can make various alterations and modifications to this application without departing from its scope. Thus, if such modifications and modifications fall within the scope of this application and its equivalents, this application intends to include such modifications and modifications.
