Description

Technical Field

[0001] This invention belongs to the field of power battery loading and transportation technology, and in particular relates to a power battery disassembly and transportation device for new energy mining trucks and its usage method. Background Technology

[0002] As the core power source of new energy trucks, batteries have the advantage of being renewable energy sources. Battery swapping technology is widely used due to its fast charging speed. Currently, the mainstream battery swapping methods in the industry mainly include battery swapping stations and forklift-type battery swapping. Battery swapping stations have the advantage of high automation, requiring no manual intervention during the swapping process, but the location of the battery swapping stations is fixed. Forklift-type battery swapping, on the other hand, can be moved flexibly to replace batteries for trucks in the field. However, in existing technologies, whether it's battery swapping at a station or using a forklift, the battery securing device and the depleted battery pack must be positioned first during the swap. After positioning, the depleted battery pack is removed using the battery securing device. After removal, the battery securing device needs to stack the depleted battery pack before securing the fully charged battery pack. After securing the fully charged battery pack, since the depleted battery pack has been removed, the battery securing device needs to be positioned a second time with the truck's battery mount. Only after the second positioning is completed can the fully charged battery pack be transported to the truck using the battery securing device. This series of transportation processes, including removing the depleted battery pack, transferring and temporarily storing it, grabbing the fully charged battery pack, and positioning it against two different reference points, takes a lot of time, resulting in low battery swapping efficiency. Moreover, the above process is carried out after the truck moves to the designated area and begins battery swapping, which means the truck has to wait a long time during the swap. Summary of the Invention

[0003] (a) Technical problems to be solved This invention provides a device for disassembling and transporting power batteries for new energy mining trucks and a method for using the same, in order to solve the following problems: The existing battery securing device completes a series of transportation processes in sequence: removing the depleted battery pack, transferring and temporarily storing it, grabbing the fully charged battery pack, secondary positioning, and installing the fully charged battery pack. Moreover, the above processes are carried out after the truck moves to the designated area and performs the battery swap, which results in a long waiting time for the truck during the battery swap.

[0004] (II) Technical Content To achieve the above objectives, the present invention provides the following technical solution: A new energy mining truck power battery disassembly and transportation device includes a docking frame and six rails. The six rails are fixed to the same side of the docking frame in pairs, and the three groups of rails are distributed vertically from top to bottom. Two sets of rails at the top and bottom are respectively equipped with mobile platforms. Winches are installed on the two mobile platforms respectively. A battery support structure is fixedly connected to the end of the sling of the winch. The battery support structure includes a base. The base is located below the corresponding winch. The end of the winch's sling is fixedly connected to the corresponding base. A bracket is symmetrically rotatably connected to the base. A push component for controlling the rotation of the bracket is provided on the base. A synchronous locking structure is symmetrically arranged on one set of rails in the middle. The synchronous locking structure can be detachably locked with the two moving platforms.

[0005] Furthermore, there are four brackets, which are arranged symmetrically in pairs on the base; The bracket includes a connecting shaft and a support plate. The connecting shaft is rotatably connected to the base. The top and bottom of the connecting shaft extend out of the base. The support plate is horizontally fixed to the shaft of the corresponding connecting shaft located below the base. The push assembly is provided with multiple components and corresponds one-to-one with multiple serial shafts. The push assembly includes a first positioning shaft, a first hydraulic telescopic device and a rocker arm. The rocker arm is horizontally fixed to the shaft of the corresponding serial shaft located above the base. A second positioning shaft is fixed to the rocker arm and is perpendicular to the rocker arm. A support is provided on the base, and the first positioning shaft is fixed to the support. The first positioning shaft is parallel to the second positioning shaft. The telescopic end of the first hydraulic telescopic device is rotatably sleeved on the second positioning shaft, and the cylinder end is rotatably sleeved on the first positioning shaft.

[0006] Furthermore, reinforcing ribs are provided between the docking frame and the rails; Guide grooves are provided on the rails; Two first traveling wheels are rotatably connected to the side wall of the mobile platform near the corresponding two rails via a shaft. The first traveling wheels on both sides of the mobile platform are symmetrically distributed, and the two first traveling wheels located on the same side wall are rolled in the guide groove on the same side. The mobile platform is equipped with a gear-type dual-axis reduction motor, which is located between one of the first traveling wheels symmetrically distributed on both sides of the mobile platform. The two output shafts of the gear-type dual-axis reduction motor are respectively fixedly connected to the shafts corresponding to the two first traveling wheels.

[0007] Furthermore, brakes are installed on one of the first traveling wheels symmetrically distributed on both sides of the mobile platform.

[0008] Furthermore, a synchronous locking structure is provided on the side of the two intermediate rails that are close to each other. The synchronous locking structure includes a hydraulic cascade plate and a second hydraulic expansion joint. Multiple shaft head holders are symmetrically fixed to the sides of the two mobile platforms that are close to each other; There are two hydraulic connector plates. On the side of the two hydraulic connector plates that are far apart, multiple second hydraulic expansion joints corresponding to the shaft head brackets are fixedly connected in an up-down manner. The extension end of each second hydraulic expansion joint is inserted into the corresponding shaft head bracket. Two second traveling wheels are rotatably connected to the opposite side of the two hydraulic actuator connecting plates via a shaft. The two second traveling wheels on the same hydraulic actuator connecting plate are rolled in the guide groove on the same side.

[0009] Furthermore, each of the two mobile platforms has an alignment slot on the side near the docking frame, and two positioning blocks are fixed on the side of the docking frame near the mobile platform. The positions of the two positioning blocks correspond to the two alignment slots, and the positioning blocks are intermittently inserted into the corresponding alignment slots. Two positioning blocks are fitted with push-button switches on the side near the alignment slots. When the positioning blocks are inserted into the corresponding alignment slots, the push-button switches are pressed against the inner wall of the alignment slots.

[0010] Furthermore, a visual locator is embedded at the bottom of the base below.

[0011] Furthermore, the geared dual-shaft reduction motor, brake, second hydraulic expansion joint, push-button switch, and visual positioner are all electrically connected to the external control terminal.

[0012] Furthermore, it also includes a battery pack, which includes a battery frame 81, inside which a power supply battery is placed, and a crossbeam is fixed to the top of the battery frame 81.

[0013] A method for using a new energy mining truck power battery disassembly and transportation device includes the following steps: S1: Before starting the battery swapping process, lift the fully charged battery pack: Before a truck that needs to replace its battery moves to a designated area, the new energy mining truck power battery disassembly and transportation device lifts the fully charged battery pack. During the lifting process, the axle head seat on the upper moving platform is separated from the telescopic end of the corresponding second hydraulic telescopic device. The gear-type dual-axis reduction motor on the lower moving platform drives the corresponding first traveling wheel to rotate, so that the moving platform moves away with the hydraulic device series plate. The mobile platform located above lowers the base using a corresponding winch. When the pallet is lowered to below the crossbeam of the fully charged battery pack, the first hydraulic telescopic device is activated. The telescopic end of the first hydraulic telescopic device extends and pushes the second positioning shaft, causing the rocker arm to rotate the connecting shaft. This causes the free end of the pallet to rotate out from the side of the base, moving it directly below the crossbeam of the fully charged battery pack. Then, the base is lifted by the winch, and the fully charged battery pack is supported by the pallet. After the lifting of the fully charged battery pack is completed, the two moving platforms move together along the direction close to the positioning block under the action of the corresponding geared dual-axis reduction motors. When the free end of the positioning block is in contact with the inner wall of the corresponding alignment slot, the shaft head bracket of the upper moving platform is vertically aligned with the telescopic end of the corresponding second hydraulic telescopic device. At the same time, when the free end of the positioning block is in contact with the inner wall of the corresponding alignment slot, the push switch is pressed. At this time, the push switch sends an electrical signal to the geared dual-axis reduction motor, the brake, and the second hydraulic telescopic device corresponding to the upper shaft head bracket. After receiving the electrical signal, the geared dual-axis reduction motor stops working, the brake brakes and locks the first traveling wheel, and the telescopic end of the corresponding second hydraulic telescopic device extends and is inserted into the shaft head bracket of the upper moving platform. S2: During battery swapping: After the truck moves to the designated area, the upper geared dual-shaft reduction motor starts, while the lower geared dual-shaft reduction motor does not start. The upper geared dual-shaft reduction motor drives the corresponding moving platform to move in the direction closer to the truck. At the same time, under the action of the synchronous locking structure, it drives the other moving platform to move synchronously. When the lower battery lifting structure moves directly above the depleted battery pack, the upper geared dual-shaft reduction motor stops working. At the same time, the upper brake brakes and locks the corresponding first traveling wheel. Then, the lower winch lowers the corresponding base. When the pallet is lowered to below the crossbeam of the depleted battery pack, the first hydraulic telescopic device is activated. The telescopic end of the first hydraulic telescopic device extends and pushes the second positioning shaft, causing the rocker arm to drive the connecting shaft to rotate. This causes the free end of the pallet to rotate out from the side of the base, moving it directly below the crossbeam of the depleted battery pack. Then, the winch lifts the base and lifts the depleted battery pack through the pallet. After the depleted battery pack is separated from the truck, the extension end of the second hydraulic telescoping device located at the upper axle head bracket retracts. At this time, the upper moving platform separates from the synchronous locking structure. Then, the gear-type dual-shaft reduction motor located below starts, causing the lower moving platform to move along the direction close to the docking frame with the depleted battery pack, removing the depleted battery pack from the truck. When the depleted battery pack is removed from the truck, the winch located above begins to lower the battery lifting structure, placing the fully charged battery pack onto the truck. After the fully charged battery pack is engaged with the truck, the corresponding extension end of the first hydraulic telescopic device retracts. The extension end of the first hydraulic telescopic device pulls the rocker arm through the second positioning shaft, causing the rocker arm to drive the series shaft to rotate in the opposite direction, causing the free end of the pallet to rotate back below the base. Then, the winch lifts the battery lifting structure back to its original position, and the truck drives away.

[0014] (III) Beneficial Effects Compared with the prior art, the beneficial effects of the present invention are as follows: I. In this invention, two mobile platforms are fixed together by a synchronous locking structure and move together to the top of the depleted battery pack. The lower mobile platform uses a winch to lower the battery lifting structure to disassemble the depleted battery pack. After disassembly, the synchronous locking structure is released from one of the mobile platforms, and the lower mobile platform moves the battery pack away under the action of a geared dual-shaft reduction motor. Meanwhile, the upper mobile platform lowers the battery lifting structure using a corresponding winch to install the fully charged battery pack on the truck. This application performs the grabbing of the fully charged battery pack in advance before the truck moves to the designated area. At the same time, the synchronous locking structure eliminates the need for secondary positioning during the battery swapping process, greatly improving the battery swapping efficiency and further reducing the waiting time for the truck during battery swapping.

[0015] Second, in this invention, when the synchronous locking structure locks the two mobile platforms together, the two mobile platforms can maintain the same traveling posture and moving speed and move synchronously.

[0016] Third, in this invention, when the telescopic end of the first hydraulic telescoping device stops moving, the positions of the rocker arm, the second positioning shaft, the connecting shaft and the support plate are locked, and the support plate remains extended, providing stable support for the battery pack and preventing the support plate from shifting or shaking during the lifting process, thus reducing the risk of the battery pack accidentally falling off.

[0017] Fourth, in this invention, under the drive of the gear-type dual-shaft reduction motor, the mobile platform drives the battery pack to move slowly along the track under the action of the winch and the battery lifting structure. When the battery lifting structure moves above the battery pack, the gear-type dual-shaft reduction motor stops working, and at the same time the brake locks the corresponding first traveling wheel to ensure that the mobile platform maintains a fixed posture during the lifting and lowering of the battery pack and avoids slippage.

[0020] 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.

[0021] Example 1 like Figures 1-7 As shown, a new energy mining truck power battery disassembly and transportation device includes a docking frame 11 and six sub-rails 21. The six sub-rails 21 are fixed to the same side of the docking frame 11 in pairs, and the three groups of sub-rails 21 are distributed vertically from top to bottom. Two sets of rails 21 located at the top and bottom are respectively equipped with moving platforms 31. The moving platforms 31 are supported by the rails 21. Specifically, the rails 21 are provided with guide grooves 2101. Two first traveling wheels 33 are rotatably connected to the side walls of the moving platforms 31 near the corresponding two rails 21 via shafts. The first traveling wheels 33 are symmetrically distributed on both sides of the moving platforms 31. The two first traveling wheels 33 located on the same side wall are rolled in the guide grooves 2101 on the same side. When moving, the moving platforms 31 move along the guide grooves 2101 under the action of the first traveling wheels 33. The first traveling wheels 33 can reduce the friction between the moving platforms 31 and the rails 21. Two mobile platforms 31 are each equipped with a winch 32. The end of the sling of the winch 32 is fixed to a battery lifting structure. The battery lifting structure includes a base 41, which is located below the corresponding winch 32. The end of the sling of the winch 32 is fixed to the corresponding base 41. A bracket 42 is symmetrically rotatably connected to the base 41. A push component for controlling the rotation of the bracket 42 is provided on the base 41. When the two mobile platforms 31 grab the battery pack, the mobile platform 31 sends down the corresponding battery lifting structure through the corresponding winch 32. The fully charged battery pack is clamped by the battery lifting structure. After clamping, the battery lifting structure is lifted by the corresponding winch 32.

[0022] A synchronous locking structure is symmetrically arranged on a set of rails 21 located in the middle. The synchronous locking structure can be detachably locked with two moving platforms 31. When swapping batteries, the two moving platforms 31 are fixed together by the synchronous locking structure. Under the action of the synchronous locking structure, the two moving platforms 31 move together to the top of the depleted battery pack to be replaced. Then, the moving platform 31 located below sends down the corresponding battery lifting structure through the corresponding winch 32. The battery lifting structure is used to snap the depleted battery pack. After snapping, the corresponding winch 32 is used to lift the battery lifting structure, thereby removing the depleted battery pack from the vehicle. After the disassembly is completed, the synchronous locking structure is released from its lock with one of the mobile platforms 31. Then, the lower mobile platform 31 moves the depleted battery pack away using the corresponding winch 32 and battery lifting structure. The upper mobile platform 31 then lowers the corresponding battery lifting structure using the corresponding winch 32, thereby transporting the fully charged battery pack to the truck. After the transport is completed, the battery lifting structure stops engaging the fully charged battery pack, and then the corresponding winch 32 lifts the battery lifting structure upwards to reset it. The battery swapping operation is then complete.

[0023] Among them, staff can fix the docking frame 11 in the battery swapping warehouse to carry out battery swapping work.

[0024] Furthermore, such as Figure 5 As shown, there are four brackets 42, which are arranged symmetrically in pairs on the base 41. The bracket 42 includes a connecting shaft 421 and a support plate 422. The connecting shaft 421 is rotatably connected to the base 41. The top and bottom of the connecting shaft 421 extend out of the base 41. The support plate 422 is horizontally fixed to the shaft of the corresponding connecting shaft 421 located below the base 41. The push assembly is provided with multiple components and corresponds one-to-one with multiple serial shafts 421. The push assembly includes a first positioning shaft 51, a first hydraulic telescopic device 52 and a rocker arm 53. The rocker arm 53 is horizontally fixed to the shaft of the corresponding serial shaft 421 located above the base 41. A second positioning shaft 54 ​​is fixed to the rocker arm 53 and is perpendicular to the rocker arm 53. A support 411 is provided on the base 41. The first positioning shaft 51 is fixed to the support 411. The first positioning shaft 51 is parallel to the second positioning shaft 54. The telescopic end of the first hydraulic telescopic device 52 is rotatably sleeved on the second positioning shaft 54, and the cylinder end is rotatably sleeved on the first positioning shaft 51.

[0025] When the telescopic end of the first hydraulic telescopic device 52 extends, the telescopic end of the first hydraulic telescopic device 52 pushes the rocker arm 53 through the second positioning shaft 54, causing the rocker arm 53 to drive the connecting shaft 421 to rotate, thereby causing the free end of the tray 422 to rotate out from the side of the base 41. When the telescopic end of the first hydraulic telescopic device 52 retracts, the telescopic end of the first hydraulic telescopic device 52 pulls the rocker arm 53 through the second positioning shaft 54, causing the rocker arm 53 to drive the connecting shaft 421 to rotate in the opposite direction, so that the free end of the pallet 422 rotates back below the base 41.

[0026] Among them, such as Figure 7 As shown, the new energy mining truck power battery disassembly and transportation device also includes a battery pack, which includes a battery frame 81. The battery frame 81 contains the power supply battery, which can be protected by the battery frame 81. A crossbeam 811 is fixed to the top of the battery frame 81. When the battery pack is lifted, the base 41 is lowered under the action of the winch 32. When the pallet 422 is lowered to below the crossbeam 811 of the battery pack, the first hydraulic telescopic device 52 is activated. The telescopic end of the first hydraulic telescopic device 52 extends and pushes the second positioning shaft 54, causing the rocker arm 53 to drive the connecting shaft 421 to rotate. This causes the free end of the pallet 422 to rotate out from the side of the base 41 and move it to directly below the crossbeam 811 of the battery pack. Then, the base 41 is lifted under the action of the winch 32, and the battery pack is lifted under the action of the pallet 422.

[0027] When the telescopic end of the first hydraulic telescopic device 52 stops moving, the positions of the rocker arm 53, the second positioning shaft 54, the connecting shaft 421 and the support plate 422 are locked, and the support plate 422 remains extended, providing stable support for the battery pack and preventing the support plate 422 from shifting or shaking during the lifting process, thus reducing the risk of the battery pack accidentally falling off.

[0028] The bracket 42 is configured as four, and the four brackets 42 are symmetrically arranged in pairs on the base 41 to achieve symmetrical support for the battery pack, so that the battery pack maintains a horizontal posture during the lifting process and prevents tilting and shaking.

[0029] Furthermore, such as Figure 1 As shown, a reinforcing rib is provided between the docking frame 11 and the rail 21. The reinforcing rib can increase the support area and support rigidity of the docking frame 11 on the rail 21, and prevent the connection between the docking frame 11 and the rail 21 from breaking due to excessive load when the moving platform 31 moves to the end of the rail 21 away from the docking frame 11. During implementation, the staff can adaptively select the length, thickness and number of reinforcing ribs according to the weight of the battery pack to be lifted and the overhang length of the rail 21, so as to meet different heavy load requirements.

[0030] The mobile platform 31 is equipped with a gear-type dual-axis reduction motor 34. The gear-type dual-axis reduction motor 34 is located between a set of first traveling wheels 33 symmetrically distributed on both sides of the mobile platform 31. The two output shafts of the gear-type dual-axis reduction motor 34 are respectively fixedly connected to the shafts corresponding to the two first traveling wheels 33. The gear-type dual-axis reduction motor 34 can drive the corresponding first traveling wheels 33 to rotate through the shafts, thereby providing power to the mobile platform 31. The use of gear-type dual-axis reduction motor 34 can increase the torque, so that the mobile platform 31 can drive the battery pack to move under the action of the winch 32 and the battery lifting structure. At the same time, this type of motor has no self-locking function after power failure, and its output shaft can rotate freely under the action of external force.

[0031] Furthermore, such as Figures 2-4 As shown, brakes 36 are installed on a set of first traveling wheels 33 symmetrically distributed on both sides of the mobile platform 31. Driven by the gear-type dual-shaft reduction motor 34, the mobile platform 31 moves the battery pack slowly along the rail 21 under the action of the winch 32 and the battery lifting structure. When the battery lifting structure moves above the battery pack, the gear-type dual-shaft reduction motor 34 stops working, and at the same time, the brakes 36 brake and lock the corresponding first traveling wheels 33 to ensure that the mobile platform 31 maintains a fixed posture during the lifting and lowering of the battery pack and avoids slippage. The brakes 36 are existing technology and can be selected from, but are not limited to, electromagnetic brakes, disc brakes, and hydraulic brakes.

[0032] Furthermore, such as Figure 6 As shown, a visual locator 71 is embedded in the bottom of the base 41 located below to assist in positioning the base 41 with the battery pack.

[0033] Furthermore, such as Figures 1-4 As shown, the two middle rails 21 are respectively provided with synchronous locking structures on their adjacent sides. The synchronous locking structures include hydraulic connector plate 62 and second hydraulic expansion joint 63. Multiple shaft head holders 35 are symmetrically fixed to the side of the two mobile platforms 31 that are close to each other; Two hydraulic coupling plates 62 are provided. On the side of the two hydraulic coupling plates 62 that are far apart, multiple second hydraulic telescopic devices 63 corresponding one-to-one with the shaft head holders 35 are fixedly connected. When the two moving platforms 31 are locked, the telescopic end of each second hydraulic telescopic device 63 on the hydraulic coupling plate 62 can be inserted into the corresponding shaft head holder 35. When one of the moving platforms 31 needs to be separated from the synchronous locking structure, the telescopic end of the corresponding second hydraulic telescopic device 63 can be retracted to separate it from the shaft head holder 35 set on the moving platform 31, so that the synchronous locking structure can be disassembled separately later.

[0034] Two second traveling wheels 61 are rotatably connected to the opposite sides of the two hydraulic assemblies 62 via a shaft. The two second traveling wheels 61 on the same hydraulic assemblies 62 are rolled in the guide groove 2101 on the same side. The guide rail 21 provides limiting support for the second traveling wheels 61 through the guide groove 2101, thereby providing auxiliary support for the hydraulic assemblies 62 through the second traveling wheels 61 and the corresponding shaft. Additionally, if it is necessary to separate the lower mobile platform 31 from the synchronous locking structure, after the lower mobile platform 31 is separated from the synchronous locking structure, the guide rail 21 will support the second traveling wheel 61 through the guide groove 2101, thereby preventing the hydraulic unit connecting plate 62 from falling off the new energy mining truck power battery disassembly and transportation device. Meanwhile, the upper axle head card 35 and the corresponding extension end of the second hydraulic telescopic device 63 are still in the plugging state, ensuring that the hydraulic unit connecting plate 62 will not deviate.

[0035] In practice, when lifting a fully charged battery pack, the shaft head bracket 35 of the upper moving platform 31 is separated from the telescopic end of the corresponding second hydraulic telescopic device 63; the lower moving platform 31 is connected to the telescopic end of the corresponding second hydraulic telescopic device 63 through the shaft head bracket 35, and at the same time, the gear-type dual-shaft reduction motor 34 at the bottom drives the corresponding first traveling wheel 33 to rotate, so that the lower moving platform 31 moves away with the hydraulic device connecting plate 62; ensuring that the lower moving platform 31 will not cause interference during the process of the upper moving platform 31 lifting the fully charged battery pack under the action of the winch 32 and the battery lifting structure.

[0036] Furthermore, a push-button switch 12 is embedded on the side of the two positioning blocks 111 near the alignment slot 3101. When the positioning blocks 111 are inserted into the corresponding alignment slot 3101, the push-button switch 12 is pressed against the inner wall of the alignment slot 3101.

[0037] Furthermore, the gear-type dual-shaft reduction motor 34, brake 36, second hydraulic telescopic device 63, push-button switch 12 and visual locator 71 are all electrically connected to the external control terminal to facilitate unified control by staff.

[0038] In practice, after the lifting of the fully charged battery pack is completed, the two moving platforms 31 move together along the direction close to the positioning block 111 under the action of the corresponding gear-type dual-axis reduction motor 34. When the free end of the positioning block 111 is in contact with the inner wall of the corresponding alignment slot 3101, the shaft head seat 35 of the upper moving platform 31 corresponds vertically to the telescopic end of the corresponding second hydraulic telescopic device 63. At the same time, when the free end of the positioning block 111 is in contact with the inner wall of the corresponding alignment slot 3101, the push switch 12 is pressed. At this time, the push switch 12 will send an electrical signal to the gear-type dual-axis reduction motor 34, the brake 36, and the second hydraulic telescopic device 63 corresponding to the upper shaft head bracket 35. After receiving the electrical signal, the gear-type dual-axis reduction motor 34 stops working, the brake 36 brakes and locks the first traveling wheel 33, and the telescopic end of the corresponding second hydraulic telescopic device 63 is inserted into the shaft head bracket 35 located on the upper moving platform 31.

[0039] In summary, the workflow and usage method of this invention are as follows: S1: Before starting the battery swapping process, lift the fully charged battery pack: Before a truck that needs battery replacement moves to a designated area, the new energy mining truck power battery disassembly and transportation device will lift the fully charged battery pack in advance. At this time, the axle head bracket 35 located on the upper moving platform 31 is separated from the telescopic end of the corresponding second hydraulic telescopic device 63. The gear-type dual-axis reduction motor 34 on the lower moving platform 31 drives the corresponding first traveling wheel 33 to rotate, so that the moving platform 31 moves away with the hydraulic device series plate 62. The upper mobile platform 31 lowers the base 41 via the corresponding winch 32. When the pallet 422 is lowered to below the crossbeam 811 of the fully charged battery pack, the first hydraulic telescopic device 52 is activated. The telescopic end of the first hydraulic telescopic device 52 extends and pushes the second positioning shaft 54, causing the rocker arm 53 to drive the connecting shaft 421 to rotate. This causes the free end of the pallet 422 to rotate out from the side of the base 41, moving it directly below the crossbeam 811 of the fully charged battery pack. Then, under the action of the winch 32, the base 41 is lifted, and under the action of the pallet 422, the fully charged battery pack is lifted. After the lifting of the fully charged battery pack is completed, the two moving platforms 31 move together along the direction close to the positioning block 111 under the action of the corresponding geared dual-axis reduction motors 34. When the free end of the positioning block 111 is in contact with the inner wall of the corresponding alignment slot 3101, the shaft head seat 35 of the upper moving platform 31 corresponds vertically to the telescopic end of the corresponding second hydraulic telescopic device 63. At the same time, when the free end of the positioning block 111 is in contact with the inner wall of the corresponding alignment slot 3101, the push-button switch... When 12 is squeezed, the push-button switch 12 sends an electrical signal to the gear-type dual-shaft reduction motor 34, the brake 36, and the second hydraulic telescopic device 63 corresponding to the upper axle head bracket 35. After receiving the electrical signal, the gear-type dual-shaft reduction motor 34 stops working, the brake 36 brakes and locks the first traveling wheel 33, and the corresponding second hydraulic telescopic device 63 extends its telescopic end and plugs into the axle head bracket 35 located on the upper moving platform 31.

[0040] S2: During battery swapping: After the truck moves to the designated area, the upper gear-type dual-shaft reduction motor 34 starts (the lower gear-type dual-shaft reduction motor 34 does not start). The upper gear-type dual-shaft reduction motor 34 drives the corresponding moving platform 31 to move in the direction closer to the truck. At the same time, under the action of the synchronous locking structure, it drives another moving platform 31 to move synchronously. When the lower battery lifting structure moves directly above the depleted battery pack, the upper gear-type dual-shaft reduction motor 34 stops working, and at the same time, the upper brake 36 brakes and locks the corresponding first traveling wheel 33. Then, the winch 32 located below lowers the corresponding base 41. When the pallet 422 is lowered to below the crossbeam 811 of the depleted battery pack, the first hydraulic telescopic device 52 is activated. The telescopic end of the first hydraulic telescopic device 52 extends and pushes the second positioning shaft 54, causing the rocker arm 53 to drive the connecting shaft 421 to rotate. This causes the free end of the pallet 422 to rotate out from the side of the base 41, moving it to directly below the crossbeam 811 of the depleted battery pack. Then, the winch 32 lifts the base 41 and supports the depleted battery pack through the pallet 422.

[0041] After the depleted battery pack is separated from the truck, the extension end of the second hydraulic telescoping device 63 located at the upper axle head bracket 35 retracts. At this time, the upper moving platform 31 separates from the synchronous locking structure. Then, the lower gear-type dual-shaft reduction motor 34 starts, causing the lower moving platform 31 to move along the direction close to the docking frame 11 with the depleted battery pack, and remove the depleted battery pack from the truck. When the depleted battery pack is removed from the truck, the winch 32 located above begins to lower the battery lifting structure, placing the fully charged battery pack onto the truck. After the fully charged battery pack is engaged with the truck, the corresponding extension end of the first hydraulic telescopic device 52 retracts. The extension end of the first hydraulic telescopic device 52 pulls the rocker arm 53 through the second positioning shaft 54, causing the rocker arm 53 to drive the connecting shaft 421 to rotate in the opposite direction, causing the free end of the pallet 422 to rotate back below the base 41. Then, the winch 32 lifts the battery lifting structure and resets it.

[0042] The battery swapping operation is now complete. As the truck leaves the swapping area and the next truck enters, the upper mobile platform 31 grabs the new fully charged battery pack, while the lower mobile platform 31 lowers the recovered depleted battery pack to the designated location. (During lowering: the lower mobile platform 31 uses a winch 32 to lower the base 41; once the bottom of the depleted battery pack contacts the ground of the battery storage area, the telescopic end of the first hydraulic telescopic device 52 on the base 41 retracts.) When the telescopic end of the first hydraulic telescopic device 52 retracts, it pulls the second positioning shaft 54 ​​in the opposite direction, causing the rocker arm 53 to drive the series shaft 421 to rotate in the opposite direction. At this time, the support plate 422 located directly below the battery pack beam 811 rotates back to the base 41 to reset, thereby canceling the lifting of the battery pack. After the support plate 422 is reset, the base 41 can be lifted and reset by the winch 32. After the depleted battery pack is placed and the fully charged battery pack is picked up, the two mobile platforms 31 lock together again through the synchronous locking structure to carry out the next battery swapping operation.

[0043] Existing power battery removal and transportation equipment requires a series of transportation processes during battery swapping, including the removal of depleted battery packs, temporary transfer and storage, grabbing of fully charged battery packs, secondary positioning, and installation of fully charged battery packs. These processes are carried out after the truck moves to the designated area and performs the battery swapping, resulting in long waiting times for the truck during the swapping process.

[0044] Compared to existing technologies, this application performs the grabbing of a fully charged battery pack before the truck moves to the designated area. At the same time, the synchronous locking structure eliminates the need for secondary positioning during the battery swapping process, which greatly improves the battery swapping efficiency and further reduces the waiting time for the truck during the swapping process.

[0045] However, as is well known to those skilled in the art, the working principles and wiring methods of the push-button switch 12, the gear-type dual-shaft reduction motor 34, the brake 36, the first hydraulic telescopic device 52, the second hydraulic telescopic device 63, and the visual positioner 71 are commonplace and belong to conventional means or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

8. The method of using the new energy mining truck power battery disassembly and transportation device according to claim 7, characterized in that, Includes the following steps: S1: Before starting the battery swapping process, lift the fully charged battery pack: Before a truck that needs to replace its battery moves to a designated area, the new energy mining truck power battery disassembly and transportation device lifts the fully charged battery pack. During the lifting process, the axle head bracket (35) on the upper moving platform (31) is separated from the telescopic end of the corresponding second hydraulic telescopic device (63). The gear-type dual-axis reduction motor (34) on the lower moving platform (31) drives the corresponding first traveling wheel (33) to rotate, so that the moving platform (31) moves away with the hydraulic device connecting plate (62). The mobile platform (31) located above lowers the base (41) via the corresponding winch (32). When the pallet (422) is lowered to below the crossbeam (811) of the fully charged battery pack, the first hydraulic telescopic device (52) is activated. The telescopic end of the first hydraulic telescopic device (52) extends and pushes the second positioning shaft (54), causing the rocker arm (53) to drive the connecting shaft (421) to rotate. This causes the free end of the pallet (422) to rotate out from the side of the base (41) and move it directly below the crossbeam (811) of the fully charged battery pack. Then, under the action of the winch (32), the base (41) is lifted, and the fully charged battery pack is lifted by the pallet (422). After the lifting of the fully charged battery pack is completed, the two moving platforms (31) move together along the direction close to the positioning block (111) under the action of the corresponding geared dual-axis reduction motor (34). When the free end of the positioning block (111) is in contact with the inner wall of the corresponding alignment slot (3101), the shaft head seat (35) of the upper moving platform (31) is vertically aligned with the telescopic end of the corresponding second hydraulic telescopic device (63). At the same time, when the free end of the positioning block (111) is in contact with the inner wall of the corresponding alignment slot (3101), the push-button switch (12) is activated. When pressed, the push-button switch (12) sends an electrical signal to the geared dual-shaft reduction motor (34), the brake (36), and the second hydraulic telescopic device (63) corresponding to the upper shaft head bracket (35). After receiving the electrical signal, the geared dual-shaft reduction motor (34), the brake (36), and the second hydraulic telescopic device (63) stop working, the brake (36) brakes and locks the first traveling wheel (33), and the corresponding second hydraulic telescopic device (63) extends its telescopic end and plugs into the shaft head bracket (35) located on the upper moving platform (31). S2: During battery swapping: After the truck moves to the designated area, the upper geared dual-shaft reduction motor (34) starts, while the lower geared dual-shaft reduction motor (34) does not start. The upper geared dual-shaft reduction motor (34) drives the corresponding moving platform (31) to move in the direction closer to the truck. At the same time, under the action of the synchronous locking structure, it drives the other moving platform (31) to move synchronously. When the lower battery lifting structure moves directly above the depleted battery pack, the upper geared dual-shaft reduction motor (34) stops working, and at the same time, the upper brake (36) brakes and locks the corresponding first traveling wheel (33). Then the winch (32) located below lowers the corresponding base (41). When the pallet (422) is lowered to the crossbeam (811) of the depleted battery pack, the first hydraulic telescopic device (52) is activated. The telescopic end of the first hydraulic telescopic device (52) extends and pushes the second positioning shaft (54), causing the rocker arm (53) to drive the connecting shaft (421) to rotate. This causes the free end of the pallet (422) to rotate out from the side of the base (41) and move it to the crossbeam (811) of the depleted battery pack. Then the winch (32) lifts the base (41) and lifts the depleted battery pack through the pallet (422). After the depleted battery pack is separated from the truck, the extension end of the second hydraulic telescoping device (63) located at the upper axle head bracket (35) retracts. At this time, the upper moving platform (31) separates from the synchronous locking structure. Then, the lower gear-type dual-shaft reduction motor (34) starts, causing the lower moving platform (31) to move along the direction close to the docking frame (11) with the depleted battery pack, and remove the depleted battery pack from the truck. When the depleted battery pack is removed from the truck, the winch (32) located above begins to lower the battery lifting structure, placing the fully charged battery pack onto the truck. After the fully charged battery pack is engaged with the truck, the corresponding first hydraulic telescopic device (52) retracts its telescopic end. The telescopic end of the first hydraulic telescopic device (52) pulls the rocker arm (53) through the second positioning shaft (54), causing the rocker arm (53) to drive the connecting shaft (421) to rotate in the opposite direction, causing the free end of the pallet (422) to rotate back below the base (41). Then the winch (32) lifts the battery lifting structure back to its original position, and the truck drives away.
