[0015] The present invention achieves the following technical effects compared to the prior art: This invention provides an after-sales tooling vehicle and its usage method for quickly disassembling and assembling energy storage PACK products. Through the coordinated operation of a mobile chassis, auxiliary support mechanism, lifting platform and push-pull mechanism, the rapid disassembly and assembly of energy storage PACK products in complex field environments is realized.

[0016] Furthermore, the mobile chassis is electrically driven, with an electric handle for flexible operation. A built-in battery pack provides power, and the forklift slot at the bottom accommodates the overall handling needs in special circumstances.

[0017] Furthermore, the auxiliary support mechanism adopts a spiral jack structure, which achieves multi-angle position locking through the cooperation of the adapter disc and the adapter rod, ensuring the stability of the vehicle during operation; Furthermore, the lifting platform is driven by a hydraulic system, achieving smooth lifting through the synchronous action of dual hydraulic cylinders. The non-powered roller design reduces frictional resistance during battery pack transfer. The push-pull mechanism uses chain drive, with a rotary motor driving the moving platform reciprocating via a reducer, drive shaft, and transmission chain. This, combined with push rods and chains, enables the battery pack to be pushed out and pulled in. A safety protection system consisting of limit switches and electric lifting limiters effectively prevents overtravel and the risk of battery pack slippage.

[0018] Furthermore, the dual-mode control design of the control box and remote control not only meets the need for precise adjustment at close range, but also enables safe operation remotely.

[0019] This invention effectively solves the problems of high labor intensity, low efficiency, and poor accuracy of traditional manual operations, as well as the high cost, poor adaptability, and numerous safety hazards of forklift operations, significantly improving the convenience, efficiency, and safety of after-sales maintenance operations for energy storage projects.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] The purpose of this invention is to provide an after-sales tooling vehicle and its usage method for quickly disassembling and assembling energy storage PACK products, so as to solve the problems existing in the prior art. It can adapt to the complex road conditions at energy storage project sites, effectively improve the convenience of operation, effectively improve the work efficiency, and effectively enhance the safety of operation.

[0024] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Example 1 This embodiment provides an aftermarket tooling vehicle for quickly assembling and disassembling energy storage PACK products, such as... Figures 1-5 As shown, the system includes: a mobile chassis 1, multiple auxiliary support mechanisms 2, a lifting platform 3, and a push-pull mechanism 4. The bottom of the mobile chassis 1 is equipped with multiple wheels 11. Each auxiliary support mechanism 2 is located around the mobile chassis 1, and the height of the auxiliary support mechanism 2 is adjustable to keep the mobile chassis 1 stable during operation. The lifting platform 3 is installed on the mobile chassis 1, and the top of the lifting platform 3 is equipped with a non-powered roller for supporting the battery pack. The lifting platform 3 can be raised and lowered to match the height of the non-powered roller with that of the battery pack to be installed or removed. The push-pull mechanism 4 is installed on the lifting platform 3, and the moving end of the push-pull mechanism 4 can reciprocate along the length of the lifting platform 3 to pull the battery pack out or push it in. This structural design clarifies the basic composition and functions of each part of the after-sales tooling vehicle. The mobile chassis 1, equipped with wheels 11, enables the movement of the workpiece; the auxiliary support mechanism 2 ensures the stability of the workpiece during operation through height adjustment; the lifting platform 3 can be adjusted in height to match the position of the battery pack, and the unpowered rollers on its top facilitate the placement and movement of the battery pack; the push-pull mechanism 4 enables the battery pack to be pulled out and pushed in. The whole system works in coordination, effectively solving the problem of rapid disassembly and assembly of battery packs in energy storage PACK products and improving after-sales work efficiency.

[0026] In a preferred embodiment, the mobile chassis 1 is an electric mobile chassis 1. An electric moving handle 12 is provided on one side of the electric mobile chassis 1 in the width direction. The electric moving handle 12 is used to control the start, stop, steering, and speed adjustment of the traveling wheels 11. The electric mobile chassis 1 has a built-in battery pack, which is electrically connected to the drive motor of the traveling wheels 11. A forklift slot 13 is provided at the bottom of the electric mobile chassis 1 for forklift forks to insert, facilitating the overall transport of the aftermarket tooling vehicle. The electric mobile chassis 1, combined with the electric moving handle 12, makes the operation of the tooling vehicle more convenient, allowing operators to flexibly control the vehicle's movement and adapt to different work scenarios. The built-in battery pack powers the drive motor of the traveling wheels 11, eliminating the limitation of an external power source and enhancing the mobility of the tooling vehicle. The forklift slot 13 at the bottom facilitates forklift handling, improving the efficiency of transferring the tooling vehicle to different work locations.

[0027] In a preferred embodiment, the electric moving handle 12 is equipped with a key-activated switch, a forward button, and a reverse button. The key-activated switch increases the safety of the tooling cart and prevents accidental activation. The forward and reverse buttons are simple and direct in design, allowing operators to quickly control the tooling cart's direction of travel and improving operational efficiency.

[0028] In a preferred embodiment, the auxiliary support mechanism 2 includes a lifting outrigger 21, a support foot pad 22, a connecting disc 23, a connecting rod 24, and a locking rod 25. The connecting disc 23 is fixedly connected to the movable base 1. One end of the connecting rod 24 is rotatably connected to the center of the connecting disc 23. The connecting disc 23 has multiple through holes on its circumference. The locking rod 25 is threadedly connected to the connecting rod 24, and one end of the locking rod 25 is used to insert into a through hole on the connecting disc 23 to lock the position of the connecting rod 24. The support foot pad 22 is located at the bottom of the lifting outrigger 21. This auxiliary support mechanism 2 is designed to be flexible and stable. The connecting disc 23 is fixed to the movable base 1, and the connecting rod 24 is rotatable. By engaging the locking rod 25 with the through hole on the connecting disc 23, the support angle can be flexibly adjusted to adapt to different ground conditions. The support foot pads 22 increase the contact area and friction with the ground, and the lifting outriggers 21 are height-adjustable, together ensuring the stability of the tooling vehicle when operating on various complex terrains.

[0029] In a preferred embodiment, the lifting outrigger 21 is a screw jack. The screw jack, as the lifting outrigger 21, has a simple structure and is easy to operate. The height can be precisely adjusted by rotating the screw, providing a reliable height adjustment function for the tooling vehicle and ensuring that the tooling vehicle can maintain horizontal stability under different ground conditions, thus meeting the needs of different working environments.

[0030] In a preferred embodiment, the system further includes a first vertical support 31, a second vertical support, a first slide 32, a second slide, multiple first transmission chains 35, multiple first steering sprockets, multiple second transmission chains, multiple second steering sprockets, an oil pump 33, a first hydraulic cylinder 34, and a second hydraulic cylinder. The first vertical support 31 and the second vertical support are respectively fixed to both sides of the top width direction of the movable chassis 1. The first slide 32 and the second slide are respectively slidably connected to the first vertical support 31 and the second vertical support in the vertical direction. The two sides of the lifting platform 3 in the width direction are slidably connected to the first slide 32 and the second slide, respectively. The top of each first slide 32 is provided with multiple first steering sprockets. One end of each first transmission chain 35 is fixedly connected to the first vertical support 31, and the other end passes around the first steering sprocket and is fixedly connected to the lifting platform 3. The top of each second slide is provided with multiple first steering sprockets. A second steering sprocket, one end of the second transmission chain is fixedly connected to the second vertical support, and the other end passes around the second steering sprocket and is fixedly connected to the lifting platform 3; the first hydraulic cylinder 34 and the second hydraulic cylinder are respectively vertically arranged inside the first vertical support 31 and the second vertical support, and the top of the piston rod of the first hydraulic cylinder 34 and the second hydraulic cylinder are respectively fixedly connected to the first slide 32 and the second slide; the oil pump 33 is installed on one side of the width direction of the mobile chassis 1, and the oil pump 33 is connected to the first hydraulic cylinder 34 and the second hydraulic cylinder through hydraulic pipelines to drive the corresponding first slide 32 and the second slide to rise and fall in the vertical direction. The hydraulic lifting system adopts a dual-cylinder synchronous drive design. The first hydraulic cylinder 34 and the second hydraulic cylinder drive the first slide 32 and the second slide to rise and fall synchronously along the first vertical support 31 and the second vertical support, thereby realizing the stable vertical movement of the lifting platform 3. Furthermore, by sliding the corresponding first carriage 32 on the first vertical support 31 and the corresponding second carriage on the second vertical support, the initial height can be effectively reduced, facilitating transportation. Additionally, the first and second carriages increase the travel range of the lifting platform 3, allowing it to adapt to the installation and removal needs of energy storage cabinet battery packs at different heights. The first and second transmission chains, in conjunction with the first and second steering sprockets, convert the linear motion of the hydraulic cylinder into the lifting motion of the lifting platform 3, resulting in high transmission efficiency and smooth operation, effectively preventing jamming or tilting during lifting. The oil pump 33 is centrally located on one side of the mobile chassis 1, facilitating the unified layout and maintenance of hydraulic lines. Simultaneously, the rational layout of the hydraulic lines enables synchronous oil supply to both cylinders, ensuring consistency in lifting actions on both sides.

[0031] In a preferred embodiment, the inner sides of the first vertical support 31 and the second vertical support are respectively provided with first vertical guide grooves, and the outer sides of the first slide 32 and the second slide are respectively provided with first guide sliders that cooperate with the vertical guide grooves. The first guide sliders are embedded in the first vertical guide grooves and can slide along them. The cooperation between the first vertical guide grooves and the first guide sliders provides precise guidance for the sliding of the first slide 32 and the second slide, ensuring that the lifting platform 3 maintains stable vertical movement during the lifting process, avoiding deviation or shaking, further improving the accuracy and stability of the lifting platform 3, and ensuring the safety of the battery pack during the lifting process.

[0032] In a preferred embodiment, both the inner sides of the first slide 32 and the second slide are provided with second vertical guide grooves, and the outer sides of the lifting platform 3 are respectively provided with second guide sliders that cooperate with the second vertical guide grooves. The second guide sliders are embedded in the second vertical guide grooves and can slide along them. This double-layer guide structure design further enhances the motion stability of the lifting platform 3. The cooperation between the second vertical guide groove and the second guide slider allows the lifting platform 3 to slide precisely vertically along the second vertical guide groove while rising and falling with the first slide 32 and the second slide, forming a double-layer guide constraint mechanism. This design effectively disperses the off-center load torque generated when the lifting platform 3 carries the battery pack, preventing the platform from tilting or jamming under heavy load conditions, ensuring that the battery pack maintains a horizontal posture throughout the lifting process, and providing a stable and reliable working plane for subsequent push-pull operations.

[0033] In a preferred embodiment, the push-pull mechanism 4 includes a rotary motor 41, a drive shaft 42, a drive sprocket, a transmission chain 44, a driven shaft 43, a driven sprocket, a moving platform 45, a push rod 46, and a zipper. The drive shaft 42 is rotatably connected to one side of the lifting platform 3 along its length. The rotary motor 41 is mounted on one side of the lifting platform 3 along its length, and the output shaft of the rotary motor 41 is detachably connected to the drive shaft 42. The drive sprocket is sleeved and fixed to the outside of the drive shaft 42. The driven shaft 43 is rotatably connected to the side of the lifting platform 3 away from the drive shaft 42. The driven sprocket is sleeved and fixed to the outside of the driven shaft 43. The transmission chain 44 is sleeved on the drive sprocket and... The mobile platform 45 is slidably connected to the top of the lifting platform 3 on the outside of the driven sprocket. The transmission chain 44 is fixedly connected to the mobile platform 45. One end of the push rod 46 is detachably connected to the top of the mobile platform 45, and the other end is used to abut against the battery pack to push the battery pack out of the lifting platform 3. One end of the zipper is detachably connected to the mobile platform 45, and the other end is used to connect to the pull ring at the end of the battery pack to pull the battery pack into the mobile platform 45. This push-pull mechanism 4 drives the drive shaft 42 through the rotary motor 41, which in turn drives the drive sprocket, transmission chain 44, and driven sprocket to rotate, realizing the reciprocating movement of the mobile platform 45 on the top of the lifting platform 3. The push rod 46 and the zipper are used to push out and pull in the battery pack, respectively. This design makes the loading and unloading operation of the battery pack more convenient and efficient, can meet the loading and unloading needs of different battery packs, and improve the automation level of after-sales operations.

[0034] In a preferred embodiment, the device further includes a reducer 48, a connecting shaft 49, and a coupling 50. The reducer 48 is fixedly mounted on the side of the drive shaft 42 away from the rotary motor 41. One end of the connecting shaft 49 is used for transmission connection with the reducer 48, and the other end is used for transmission connection with an external rotating device. The coupling 50 is used to transmission connection between the reducer 48 and the drive shaft 42, or to transmission connection between the rotary motor 41 and the drive shaft 42. The reducer 48 can amplify the torque transmitted to the drive shaft 42 by the external rotating device, so that in the event of a failure of the rotary motor 41 or insufficient power, the torque can be transmitted through an external device. Rotating devices such as hand cranks or portable power tools drive the push-pull mechanism 4 to complete the battery pack disassembly and assembly operations, significantly improving the emergency operation capability and on-site adaptability of the after-sales tooling vehicle. The coupling 50 can switch the power source mode of the push-pull mechanism 4 by being installed in different positions. When the coupling 50 is connected to the reducer 48 and the drive shaft 42, the external rotating device can drive the drive shaft 42 to operate through the reducer 48. When the coupling 50 is connected to the rotary motor 41 and the drive shaft 42, the rotary motor 41 directly drives the drive shaft 42 to operate. The two modes do not interfere with each other and can be flexibly selected according to the actual situation on site.

[0035] In a preferred embodiment, the system further includes a first limit switch, a second limit switch 51, a third limit switch 52, and multiple electric lifting limit switches 53. The first limit switch is located on the side of the lifting platform 3 near the drive shaft 42, and the second limit switch 51 is located on the side of the lifting platform 3 near the driven shaft 43. Both the first and second limit switches 51 are electrically connected to the rotary motor 41. When the moving platform 45 touches the first limit switch, it triggers the rotary motor 41 to stop driving the moving platform 45 to continue moving away from the second limit switch 51. Similarly, when the moving platform 45 touches the second limit switch 51, it triggers the rotary motor 41 to stop driving the moving platform 45 to continue moving away from the first limit switch. An electric lifting limit switch 53 is mounted on the lifting platform 3 and located on the side of the lifting platform 3 closest to the second limit switch 51. A third limit switch 52 is mounted on the side of the first limit switch closest to the second limit switch 51 and located outside the first limit switch to avoid interfering with the movement of the moving platform 45. This allows the battery pack to fully enter the lifting platform 3 and contact the third limit switch 52. The third limit switch 52 is electrically connected to the electric lifting limit switch 53. When the battery pack contacts the third limit switch 52, it triggers the electric lifting limit switch 53 to rise, preventing the battery pack from slipping off the lifting platform 3. The limit switches provide precise control over the movement range of the moving platform 45, preventing the moving platform 45 from exceeding a reasonable range and causing equipment damage or safety accidents. The electric lifting limit switch 53 works in conjunction with the third limit switch 52. When the battery pack fully enters the lifting platform 3 and triggers the third limit switch 52, the electric lifting limit switch 53 rises, effectively preventing the battery pack from slipping and improving the safety of the battery pack during placement and movement on the lifting platform 3.

[0036] In a preferred embodiment, the system further includes a linkage switch and a mounting plate. The linkage switch is mounted on the moving platform 45 and is signal-connected to the electric lifting limiter 53. The mounting plate is also mounted on the moving platform 45 and is used to mount the push rod 46 and the zipper. After the mounting plate is installed on the moving platform 45, it closes the linkage switch, disconnecting the signal between the linkage switch and the electric lifting limiter 53. When the mounting plate is removed, the linkage switch keeps the electric lifting limiter 53 in a limited position. The height of the moving platform 45 is lower than the top surface of the unpowered roller, allowing the battery pack to be pushed onto the lifting platform 3 from the side away from the electric lifting limiter 53 after the mounting plate is removed. The design of the linkage switch and mounting plate provides a flexible limit control method. When the mounting plate is installed, the linkage switch is closed, and the electric lifting limiter 53 is still controlled by the third limit switch 52. After the mounting plate is removed, the electric lifting limiter 53 remains in a limited position, preventing the battery pack entering the lifting platform 3 from the other side from slipping off. The height design of the mobile platform 45 and the unpowered rollers avoids blocking the battery pack from being pushed in from the other side, allowing the battery pack to enter the lifting platform 3 from both sides along its length, thus improving the convenience and safety of operation.

[0037] In a preferred embodiment, the system further includes a remote controller and a control box 54. The control box 54 is mounted on one side of the mobile chassis 1. The control box 54 contains multiple control switches for controlling the connection and disconnection of the rotary motor 41, oil pump 33, and battery pack. The remote controller is wirelessly connected to the rotary motor 41 and oil pump 33. The control box 54 also contains a control knob electrically connected to the rotary motor 41 to control its rotational speed. This configuration provides operators with convenient remote and local control methods. The control switches within the control box 54 can directly control the connection and disconnection of the rotary motor 41, oil pump 33, and battery pack, while the control knob adjusts the rotational speed of the rotary motor 41. The remote controller enables wireless remote control, allowing operators to operate the workpiece from a safe distance, improving operational convenience and safety, and meeting control requirements in different work scenarios.

[0038] In a preferred embodiment, the remote control is equipped with multiple operation buttons, including an up button for the lifting platform 3, a down button for the lifting platform 3, a forward button for the push-pull mechanism 4, and a backward button for the push-pull mechanism 4. This allows operators to remotely control various functions of the after-sales tooling vehicle. The clearly defined operation button design on the remote control enables operators to quickly and accurately control the lifting platform 3 and the push-pull mechanism 4 of the after-sales tooling vehicle remotely, further improving the convenience and efficiency of operation. This allows operators to flexibly control the tooling vehicle from different positions, improving the overall efficiency and safety of after-sales operations.

[0039] In a preferred embodiment, the lifting platform 3 is further provided with a level placement station. This station is used to place a level, allowing for continuous monitoring of the platform's horizontal position before or during operation. This ensures the battery pack remains level during assembly and disassembly, preventing slippage or uneven stress due to platform tilt, thus further guaranteeing operational safety and the integrity of the battery pack. The level placement station is typically located in a prominent position on the top of the lifting platform 3 for easy access and observation by operators, improving operational efficiency.

[0040] In a preferred embodiment, horizontal position limiting rollers are provided on both sides of the lifting platform 3 in the width direction to laterally limit the battery pack placed on the lifting platform 3, preventing the battery pack from shifting or shaking laterally during the pushing and pulling process. The two horizontal position limiting rollers form an enlarged opening at the opening, which facilitates the battery pack to be quickly aligned when it slides into the lifting platform 3 from the opening, reducing the adjustment time.

[0041] In a preferred embodiment, the top of the mobile chassis 1 is also provided with a toolbox and an accessory storage area. The toolbox is used to store various special tools required for disassembling and assembling the battery pack, and the accessory storage area is used to store spare parts and consumables. The integrated design of the toolbox and accessory storage area allows all materials required for after-sales work to be carried with the vehicle, avoiding work interruptions due to the lack of tools or accessories during the operation, and improving the continuity and response speed of on-site operations.

[0042] Example 2 This invention provides a method for using an aftermarket tooling vehicle for quickly disassembling and assembling energy storage PACK products, as described in any of Embodiment 1, comprising the following steps: 1. Tooling preparation: Appearance and component inspection: Inspect all components of the tooling vehicle for damage or looseness, including the traveling wheels 11, auxiliary support mechanism 2, lifting platform 3, and push-pull mechanism 4. Check if the key start switch, forward button, and reverse button on the electric moving handle 12 are working properly, and whether the operation buttons on the remote control are sensitive.

[0043] Power supply check: Confirm that the built-in battery pack of the electric mobile chassis 1 has sufficient power, and that all control switches in the control box 54 are in their initial normal state, ensuring that equipment such as the rotary motor 41 and oil pump 33 can be powered on and operated normally.

[0044] Tools preparation: Prepare the necessary installation and disassembly tools, such as those related to push rod 46 and zipper installation.

[0045] 2. Move the tooling vehicle to the work site: Start the tooling cart: Use the key to turn on the start switch on the electric moving handle 12, control the walking wheels 11 to start via the electric moving handle 12, and operate the forward or reverse key to move the tooling cart to a suitable working position near the energy storage cabinet.

[0046] Handling assistance (optional): If the tooling cart needs to be moved over a long distance, a forklift can be used. Insert the forklift forks into the forklift slot 13 at the bottom of the electric mobile chassis 1, load the tooling cart into the truck, move it to the designated location, and then unload it by forklift.

[0047] 3. Adjust the tooling carriage status: Adjusting Auxiliary Support Mechanism 2: After reaching the work position, manually adjust the lifting outriggers 21 (screw jacks) of the auxiliary support mechanism 2 around the mobile chassis 1 according to the flatness of the ground. Rotate the adapter rod 24 to adjust the support angle, insert the locking rod 25 into the appropriate through hole on the adapter disc 23 to lock the position of the adapter rod 24, so that the support pads 22 are firmly in contact with the ground, adjust the height of the auxiliary support mechanism 2 so that the tires of the mobile chassis 1 are slightly off the ground, and ensure that the tooling vehicle is in a level and stable state.

[0048] Height adjustment of lifting platform 3: By pressing the up or down button of lifting platform 3 with remote control, the oil pump 33 is controlled to supply oil to the first hydraulic cylinder 34 and the second hydraulic cylinder, driving the first slide 32 and the second slide to slide in the vertical guide groove of the first vertical support 31 and the second vertical support, thereby driving the lifting platform 3 to rise or fall, so that the height of the unpowered roller at the top of the lifting platform 3 matches the height of the battery pack to be removed or installed.

[0049] 4. Disassemble the battery pack: Connecting zipper: One end of the zipper is detachably connected to the mounting plate on the mobile platform 45, and the other end is connected to the pull ring at the end of the battery pack.

[0050] Activating the push-pull mechanism 4: Pressing the reverse button on the push-pull mechanism 4 via the remote control starts the rotary motor 41, driving the drive shaft 42 to rotate. The drive sprocket rotates accordingly, driving the driven sprocket and driven shaft 43 to rotate via the transmission chain 44. This causes the mobile platform 45, which is fixedly connected to the transmission chain 44, to move away from the energy storage cabinet from the top of the lifting platform 3, pulling the battery pack from the energy storage cabinet onto the mobile platform 45. When the mobile platform 45 touches the first limit switch, the rotary motor 41 automatically stops, ensuring that the mobile platform 45 does not exceed the safe range.

[0051] Disconnect the zipper: After the battery pack has fully entered the lifting platform 3 and the electric lifting limiter 53 has been raised, disconnect the zipper from the end ring of the battery pack and remove the zipper from the moving platform 45 for storage.

[0052] Transferring the battery pack: After the battery pack is pulled to the mobile platform 45, the lifting platform 3 is lowered to a suitable height again by remote control. The electric moving handle 12 is then operated to move the tooling cart to the battery pack repair area.

[0053] 5. Install the battery pack: Positioning the tooling cart: Move the tooling cart to the vicinity of the energy storage cabinet installation location, and repeat step 3 to adjust the status of the tooling cart so that the height of the lifting platform 3 matches the installation location of the energy storage cabinet.

[0054] Pushing the battery pack: Pressing the forward button on the push-pull mechanism 4 via the remote control reverses the rotary motor 41, causing the moving platform 45 to move towards the energy storage cabinet. The mounting plate pushes the battery pack on the moving platform 45 into the installation space of the energy storage cabinet. Because there is a gap between the lifting platform 3 and the energy storage cabinet, the mounting plate alone cannot completely push the battery pack into the cabinet. The moving platform 45 needs to be moved a certain distance, and a push rod 46 is installed on the mounting plate. The moving platform 45 is then moved again, and the push rod 46 is used to completely push the battery pack into the installation position of the energy storage cabinet. When the moving platform 45 touches the second limit switch 51, the rotary motor 41 automatically stops to prevent excessive movement of the moving platform 45 and potential collision damage.

[0055] Disconnect push rod 46: After the battery pack is fully installed, disconnect push rod 46 from the mounting plate and remove push rod 46 from the moving platform 45 for storage.

[0056] Reset Lifting Platform 3: Control the lifting platform 3 to descend via remote control, so that the unpowered rollers are no longer in contact with the bottom of the energy storage cabinet, in preparation for the installation of the next battery pack or to end the current installation process.

[0057] 6. Safety precautions during operation: Battery pack limit: After the battery pack is fully inside the lifting platform 3, it will touch the third limit switch 52, triggering the electric lifting limiter 53 to rise and prevent the battery pack from slipping off the lifting platform 3. If the mounting plate is installed on the moving platform 45, the linkage switch is closed and the electric lifting limiter 53 does not work; when the mounting plate is removed, the linkage switch keeps the electric lifting limiter 53 in the limit state.

[0058] Emergency Handling: In case of an emergency during operation, press the emergency stop button on control box 54 or use the emergency stop function that may be set on the remote control to immediately stop all operating parts of the tooling vehicle and ensure the safety of personnel and equipment.

[0059] 7. Tooling cart repositioning and storage: Reset operation: After the battery pack is installed, use the remote control to lower the lifting platform 3 to the initial position, retract the auxiliary support mechanism 2, and make the tires of the mobile chassis 1 touch the ground.

[0060] Power off: After the operation is completed, turn off the start switch of the electric moving handle 12, disconnect the rotary motor 41 and oil pump 33 in the control box 54 from the battery pack, save power and ensure safety.

[0061] Organize and tidy up: Properly store tools such as push rod 46 and zipper, check all parts of the tooling vehicle, and prepare for the next use.
