Description

Technical Field

[0001] This utility model relates to a lifting device, specifically an integrated battery lifting device for a battery swapping station. Background Technology

[0002] In the field of electric trucks, the large number of batteries leads to long charging times. Therefore, the batteries are typically fixed to a support frame to form a replaceable battery pack, and dedicated battery swapping stations are set up to charge the packs. When the battery pack's power is insufficient, the vehicle can be driven to the swapping station for replacement, preventing disruption to normal vehicle operation. Because the battery packs are heavy, gantry cranes and associated lifting devices are commonly used for transport. Traditional lifting devices suffer from inconvenient connections and low automation, as illustrated by patent CN215946488U, which discloses a "lifting device for a power battery of a new energy vehicle." To address the problems of traditional lifting devices, those skilled in the art have developed a lifting system that automatically connects to the battery pack via electronic control, such as the "Battery Lifting System for Truck Swapping Stations" disclosed in patent publication number CN116119539A. This system includes a gantry crane and a lifting device. The gantry crane includes a longitudinal frame and a transverse frame, as well as a lifting mechanism mounted on the transverse frame, consisting of a reducer, four fixed pulleys, and four steel wire ropes. The lifting device includes a support frame, four movable pulleys, and four hook assemblies. The four movable pulleys are connected by corresponding steel wire ropes, and the four hook assemblies are controlled by two sets of drive mechanisms. The drive mechanisms include electric push rods and sliding plates. The sliding plates have elongated holes at both ends for guidance, and the sliding plates slide against the support frame via a guide rail slider structure. The guide rollers of the four hook assemblies are respectively located in the elongated holes of the corresponding sliding plates. This battery lifting system has problems such as complex structure, large space occupation, and poor stability in practical applications because the reducer and fixed pulleys are located on the transverse frame of the gantry crane, while the movable pulleys are located on the support frame of the lifting device.

[0010] Furthermore, this utility model provides an integrated battery hoist, wherein two diagonally distributed lowering detection components are installed on the docking frame.

Two proximity sensors are fixed to the vertical part of the L-shaped bracket plate through an adapter plate. A guide member is installed on the horizontal part of the L-shaped bracket plate through a guide sleeve. A retaining ring is provided at the lower end of the guide member. A reset spring is sleeved on the guide member between the retaining ring and the guide sleeve. A limiting sleeve that cooperates with the proximity sensor is fixed to the upper end of the guide member.

[0011] Furthermore, this utility model provides an integrated battery hoist, wherein two descent limit supports and two positioning columns are fixed on the docking frame. The two descent limit supports are respectively arranged on the front and rear sides of the docking frame, and a rubber buffer pad is fixed at the bottom of the descent limit support. The two positioning columns are arranged on the upper side of the docking frame and are diagonally distributed.

[0012] Furthermore, in this utility model, an integrated battery hoist is provided, wherein the two reducers are symmetrically distributed from left to right, the output shaft of the reducer is mounted on the docking frame through a bearing seat, the intermediate connecting seat is located at the front and rear middle position of the docking frame, the side connecting seats on both sides of the docking frame are symmetrically distributed, and there is a gap between the cylinder axis and the rotating shaft.

[0013] Furthermore, in this utility model, an integrated battery hoist is provided, wherein a rope pressing roller is installed on the docking frame at a position corresponding to each rope winding wheel via a wheel frame, and a cable take-up drum for storing cables is provided on the docking frame between two reducers.

[0014] Compared with existing technologies, this integrated battery hoist has the following advantages: This invention uses a docking frame and two sets of hook assemblies. Two speed reducers are mounted on the docking frame, with the input shaft of the speed reducer connected to a motor. Rope winding wheels are installed at both ends of the output shaft of the speed reducer. Four lifting ring assemblies, each corresponding to a rope winding wheel, and four proximity switches, each corresponding to a lifting ring assembly, are installed on the docking frame. Each lifting ring assembly includes a guide rod passing through the docking frame. The upper end of the guide rod has a lifting ring connected to the rope winding wheel via a wire rope. The lower end of the guide rod has an adjusting nut for adjustment. A spring seat that mates with a proximity switch is fitted on the guide rod on the upper side of the nut. A compression spring is fitted on the guide rod between the spring seat and the docking frame. The two sets of hook assemblies are arranged in a symmetrical distribution, so that the hook assemblies are fixed to the middle connecting seat at the bottom of the docking frame. Side connecting seats that are fixed to the bottom of the docking frame are respectively set on the front and rear sides of the middle connecting seat. A rotating shaft is installed on the side connecting seat, and a lifting claw is fixed at the lower end of the rotating shaft. A cylinder is set between the lifting claw and the middle connecting seat. This constitutes an integrated battery lifting device that is compact, occupies little space, is easy to operate, stable and reliable, and highly practical. In practical applications, four fixed pulleys are installed on the gantry crane's transverse frame. The wire ropes connecting the four lifting ring assemblies pass over the four fixed pulleys and are then fixed to the corresponding rope reels, thus completing the connection between the battery lifting device and the gantry crane. When lifting the battery, the gantry crane first moves the battery lifting device directly above the battery pack. Then, a speed reducer releases the wire rope from the rope reels until the battery lifting device falls onto the battery pack. Next, each cylinder drives the corresponding lifting claw to rotate to the underside of the battery pack's support frame side beam, hooking the battery pack and connecting it to the battery pack. The speed reducer then retracts the wire rope onto the rope reels until the docking frame and transverse frame are aligned. Finally, the gantry crane can move the battery pack from the charging station to the vehicle or from the vehicle to the charging position. To disconnect the battery lifting device from the battery pack, simply rotate each lifting claw back to its initial position. Compared with existing technologies, this invention simplifies the structure and improves integration by placing the reducer and rope reel on the battery hoist. This reduces the height and space occupied by the battery hoist and the entire system combined with the gantry crane. Furthermore, eliminating the moving pulley shortens the path of the wire rope during lifting, improving stability. Simultaneously, this invention uses a hoist assembly consisting of a guide rod, a hoisting ring, an adjusting nut, a spring seat, and a compression spring. When the battery hoist is connected to the gantry crane via the wire rope, the compression spring is compressed to its minimum length under gravity, aligning the spring seat with the proximity switch. During use, if the wire rope is further released after the battery hoist has landed on the battery pack, the spring seat will move downwards under the action of the compression spring, triggering the proximity switch. This achieves the purpose of detecting wire rope over-release, effectively preventing the wire rope from becoming tangled and ensuring the stability of the structure and lifting operation.In addition, by setting two sets of hook assemblies consisting of a middle connecting seat, a side connecting seat, a rotating shaft, a lifting claw, and a cylinder, the cylinder directly drives the lifting claw to rotate, eliminating the need for transmission mechanisms such as a sliding plate, guide hole, roller, guide rail, and slider, further simplifying the structure and improving the stability of the rotation.

[0026] First, it should be noted that the directional terms such as up, down, left, right, front, and back mentioned in this utility model are only descriptions based on the accompanying drawings for ease of understanding, and are not intended to limit the technical solution or the scope of protection claimed in this utility model.

[0027] like Figures 1 to 10The present invention discloses an integrated battery lifting device, comprising a docking frame 1 and two sets of hook assemblies 2. Two reducers 3 are mounted on the docking frame 1, with the input shaft of the reducers 3 connected to a motor 31. Rope winding wheels 32 are installed at both ends of the output shaft of the reducers 3. Four lifting ring assemblies 4, each corresponding to a rope winding wheel 32, and four proximity switches 5, each corresponding to a lifting ring assembly 4, are mounted on the docking frame 1. Each lifting ring assembly 4 includes a guide rod 41 passing through the docking frame 1. The upper end of the guide rod 41 has a lifting ring 42 connected to the rope winding wheel 32 via a wire rope. The lower end of the guide rod 41 is fitted with an adjusting nut 43. A spring seat 44, cooperating with the proximity switch 5, is sleeved on the guide rod 41 above the adjusting nut 43. A compression spring 45 is sleeved on the guide rod 41 between the spring seat 44 and the docking frame 1. The two sets of hook assemblies 2 are arranged in a symmetrical distribution, with the hook assemblies 2 fixed to the middle connecting seat 21 at the bottom of the docking frame 1. Side connecting seats 22 are fixed to the bottom of the docking frame 1 on the front and rear sides of the middle connecting seat 21, respectively. A rotating shaft 23 is installed on the side connecting seat 22, and a lifting claw 24 is fixed at the lower end of the rotating shaft 23. A cylinder 25 is set between the lifting claw 24 and the middle connecting seat 21.

[0028] The above configuration constitutes an integrated battery lifting device that is compact, space-saving, easy to operate, stable, reliable, and highly practical. In practical applications, four fixed pulleys are installed on the gantry crane's transverse frame. The wire ropes 100 connecting the four lifting ring assemblies 4 are wound around the four fixed pulleys and fixed to the corresponding rope reels 32, thus completing the connection between the battery lifting device and the gantry crane. When lifting batteries, the gantry crane first moves the battery lifting device directly above the battery pack. Then, the reducer 3 releases the wire rope from the rope reels 32 until the battery lifting device falls onto the battery pack. Next, the cylinders 25 drive the corresponding lifting claws 24 to rotate to the underside of the support frame side beam of the battery pack, thus hooking the battery pack and connecting it to the battery pack. Subsequently, the reducer 3 retracts the wire rope onto the rope reels 32 until the docking frame 1 and the transverse frame are docked. Finally, the gantry crane can move the battery pack from the charging position to the vehicle or from the vehicle to the charging position. To disconnect the battery lifting device from the battery pack, simply rotate each lifting claw 24 to its initial position. Compared with the prior art, this utility model simplifies the structure and improves integration by placing the reducer 3 and the rope reel 32 on the battery lifting device. This helps to reduce the height and space occupied by the battery lifting device and the entire system after being combined with the gantry crane. On the other hand, by eliminating the moving pulley, the path of the wire rope during lifting is reduced, thus improving stability. Meanwhile, this invention features a lifting ring assembly consisting of a guide rod 41, a lifting ring 42, an adjusting nut 43, a spring seat 44, and a compression spring 45. When the battery lifting device is connected to the overhead crane via a wire rope, the compression spring 45 is compressed to its minimum length under gravity, aligning the spring seat 44 with the proximity switch 5. During use, if the wire rope is further released after the battery lifting device has landed on the battery pack, the spring seat 44 will move downwards under the action of the compression spring 45, triggering the proximity switch 5. This achieves the purpose of detecting over-release of the wire rope, effectively preventing tangling and ensuring the stability of the structure and lifting action. Furthermore, this invention uses two sets of hook assemblies consisting of a middle connecting seat 21, a side connecting seat 22, a rotating shaft 23, a lifting claw 24, and a cylinder 25. The cylinder 25 directly drives the lifting claw 24 to rotate, eliminating the need for transmission mechanisms such as a sliding plate, guide hole, rollers, guide rails, and sliders, further simplifying the structure and improving the stability of the rotational action. It should be noted that, to improve structural stability and balance, this invention employs a symmetrical arrangement of the two reducers 3 for ease of use, and mounts the output shafts of the reducers 3 onto the docking frame 1 via bearing seats 14. Similarly, this invention places the intermediate connecting seat 21 at the front-to-back center of the docking frame 1, and also symmetrically arranges the side connecting seats 22 on both sides of the docking frame 1. Furthermore, to ensure that the cylinder 25 can properly drive the lifting claw 24 to rotate, the axis of the cylinder 25 should be offset from the rotating shaft 23; that is, a gap should be set between the axis of the cylinder 25 and the rotating shaft 23.

[0029] As an optimized solution, this specific embodiment fixes four symmetrically distributed transverse guide columns 6 at the bottom of the docking frame 1, and sets an inclined surface with an inner lower and outer higher direction in the front-back direction at the lower end of the transverse guide columns 6. A transverse guard plate 61 is fixed on the inclined surface and outer surface of the transverse guide columns 6. Correspondingly, an inclined surface with an outer lower and inner higher direction in the left-right direction is set at the lower end of the intermediate connecting seat 21, and a longitudinal guard plate 211 is fixed on the inclined surface and inner surface of the intermediate connecting seat 21. This arrangement allows the four transverse guide columns 6 and their inclined surfaces to provide lateral guidance and positioning when the battery hoist is lowered and docked with the battery pack, and the transverse guard plate 61 reduces noise and wear. Similarly, the intermediate connecting seats 21 of the two sets of hook assemblies 2 and their inclined surfaces provide longitudinal guidance and positioning, and the longitudinal guard plate 211 reduces noise and wear. The side beams of the battery pack's support frame act as lateral limiting blocks for the transverse guide columns 6, and the crossbeams of the battery pack's support frame act as longitudinal limiting blocks for the intermediate connecting seats 21 of the two sets of hook assemblies 2. In practical applications, the present invention typically uses nylon for the transverse guard plate 61 and the longitudinal guard plate 211.

[0030] In a specific embodiment, this invention fixes an L-shaped adapter frame 212 on the intermediate connecting seat 21, and a hinge 241 on the lifting claw 24. The cylinder body and piston rod of the cylinder 25 are respectively connected to the L-shaped adapter frame 212 and the hinge 241 via pins. This structure improves the ease of assembly and disassembly by using the L-shaped adapter frame 212 and the hinge 241, and improves the stability of the rotating action of the lifting claw 24 by using a hinged connection for the cylinder 25. In another specific embodiment, to facilitate installation and fixation, this invention provides an intermediate seat mounting plate 213 at the top of the intermediate connecting seat 21, which is bolted to the bottom of the docking frame 1. It also provides a side seat mounting plate 221 at the top of the side connecting seat 22, which is bolted to the bottom of the docking frame 1. Furthermore, it provides an upwardly extending side plate 222 on the outer side of the side connecting seat 22, which is bolted to the outer side of the docking frame 1, to enhance the connection stability. Meanwhile, in this specific embodiment, an auxiliary guard plate 223 is fixed to the outside of the side connecting seat 22, and a triangular guide block 242 is fixed to the outside of the lifting claw 24. The auxiliary guard plate 223 and the guide block 242 are made of nylon. This arrangement allows the guide block 242, the side connecting seat 22, and the auxiliary guard plate 223 to provide lateral guidance and positioning when the battery lifting device is lowered and docked with the battery pack, improving functionality and practicality. In practical applications, this invention uses the following installation method for the rotating shaft 23: a collar 231 is provided on the peripheral wall of the rotating shaft 23, a locking nut 232 is threaded onto the upper end of the rotating shaft 23, and a pressure plate 233 is fixed to the top of the rotating shaft 23 with screws. Correspondingly, a limiting ring 224 is provided on the inner wall of the shaft hole of the side connecting seat 22, and bearings 26 are respectively clamped between the limiting ring 224, the collar 231, and the locking nut 232. This structural design is stable and reliable, easy to assemble and disassemble, and has sensitive operation.

[0031] In a specific implementation, to facilitate control by detecting whether the battery hoist has fallen to the correct position, this specific implementation installs two diagonally distributed lowering detection components 7 on the docking frame 1, and the lowering detection components 7 adopt the following structure: an L-shaped bracket plate 71 is fixed on the docking frame 1, two proximity sensors 73 are fixed on the vertical part of the L-shaped bracket plate 71 through an adapter plate 72, and a guide member 75 is installed on the horizontal part of the L-shaped bracket plate 71 through a guide sleeve 74. The lower end of the guide member 75 is provided with a retaining ring 76, and a return spring 77 is sleeved on the guide member 75 between the retaining ring 76 and the guide sleeve 74. The upper end of the guide member 75 is fixed with a limiting sleeve 78 that cooperates with the proximity sensor 73. During the process of the battery hoist descending and docking with the battery pack, the support frame on the battery pack acts as a barrier to the guide 75, and the retaining ring 76 compresses the return spring 77. When the battery hoist reaches its destination, the limiting sleeve 78 triggers both proximity sensors 73, thus achieving the purpose of arrival detection. At this time, the battery pack can be hooked by rotating the lifting claw 24. After hooking the battery pack, during the process of the battery hoist rising and moving with the battery pack, the upper proximity sensor 73 will lose its signal due to the small gap between the docking frame 1 and the support frame on the battery pack. At this time, only the lower proximity sensor 73 will have a trigger signal, indicating that the battery pack is on the battery hoist, which serves as a safety reminder and can effectively prevent misoperation. When the battery hoist is disconnected from the battery pack and leaves, the guide 75 and the limiting sleeve 78 will automatically reset under the action of the return spring 77. In a specific implementation, this invention fixes two descent limit supports 11 and two positioning posts 12 on the docking frame 1. The two descent limit supports 11 are respectively positioned on the front and rear sides of the docking frame 1, and a rubber buffer pad 13 is fixed to the bottom of the descent limit supports 11. The two positioning posts 12 are positioned on the upper side of the docking frame 1 and are diagonally distributed. This arrangement ensures that when the battery hoist descends to dock with the battery pack, the buffer pad 13 will first contact the support frame on the battery pack, providing a buffering effect. When the battery hoist rises to dock with the gantry crane's transverse frame, the two positioning posts 12 are inserted into the corresponding positioning cylinders on the transverse frame, keeping the battery hoist and the transverse frame relatively fixed, thus improving stability and reliability. In practical applications, this invention also installs rope pressing rollers 16 on the docking frame 1 at positions corresponding to each rope winding wheel 32 via wheel frames 15 to block and restrict the wire rope. A take-up drum 17 is also installed on the docking frame 1 between the two reducers 3 to store the connecting cables during lifting and lowering.

[0032] The above embodiments are merely descriptions of preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications made by those skilled in the art based on the technical solution of the present utility model without departing from the design concept of the present utility model shall fall within the scope of protection defined by the claims of the present utility model.
