Description

Technical Field

[0001] This invention relates to a lifting tool, and more specifically to a battery lifting system for electric truck battery swapping stations. Background Technology

[0002] In the field of electric trucks, the large number of batteries leads to long charging times. Therefore, batteries are typically fixed to mounting frames to form a replaceable battery pack, and dedicated battery swapping stations are set up for charging these packs. When the battery pack's charge is low, the vehicle can be driven to the swapping station for replacement, preventing disruption to normal vehicle use. Because the battery packs are heavy, lifting tools are commonly used. However, existing lifting tools suffer from inconvenience, poor stability, and low automation in practical applications. For example, patent CN215946488U discloses a lifting device for a new energy vehicle power battery, and patent CN217102680U discloses a battery lifting device. Both of these methods require manual disassembly and assembly of the lifting device and battery pack, impacting work efficiency. Summary of the Invention

[0014] Compared with existing technologies, the battery hoisting system for truck battery swapping stations of this invention has the following advantages: This invention uses a gantry crane and lifting equipment, with the gantry crane fixed to two longitudinal guide rails within the battery swapping station housing. A longitudinal moving frame is mounted on the two longitudinal guide rails, and two transverse guide rails are fixed to the longitudinal moving frame.

[0029] First, it should be noted that the directional terms such as up, down, left, right, front, and back used in this invention are merely 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 invention.

[0030] like Figures 1 to 13The present invention illustrates a specific embodiment of a battery hoisting system for a truck battery swapping station, comprising a gantry crane and a lifting device. The gantry crane is mounted on two longitudinal guide rails 1 fixed within the battery swapping station housing. A longitudinal moving frame 2 is mounted on the two longitudinal guide rails 1. Two transverse guide rails 21 are fixed on the longitudinal moving frame 2. A transverse moving frame 3 is mounted on the transverse guide rails 21. A lifting mechanism is mounted on the transverse moving frame 3. The lifting mechanism includes a lifting reducer 4, four fixed pulleys 5, and four steel wire ropes 6. The lifting reducer 4 is fixed to the transverse moving frame 3. The input shaft of the lifting reducer 4 is connected to a lifting drive motor (not shown in the figure). Rope winding pulleys 41 are fixed to both ends of the output shaft of the lifting reducer 4. The four fixed pulleys 5 are correspondingly installed at the four corners of the transverse moving frame 3. One end of each of the four steel wire ropes 6 is fixedly connected to a rope winding pulley 41, and the other end of each steel wire rope 6 passes over the four fixed pulleys 5 and is fixedly connected to the transverse moving frame 3. The lifting device is set up with a support frame 8 connected to four steel wire ropes 6 via four movable pulleys 7. Four hook assemblies 9 are set on the support frame 8. Each hook assembly 9 includes a rotating shaft 91 mounted on the support frame 8 via bearings. A swing arm 92 and a hanging plate 93 are vertically fixed at the upper and lower ends of the rotating shaft 91. The swing arms 92 of the two front hook assemblies 9 are connected to the front rotation drive device, and the swing arms 92 of the two rear hook assemblies 9 are connected to the rear rotation drive device.

[0031] The above structural configuration constitutes a truck battery swapping station battery lifting system that is easy to operate, stable, adaptable, and highly efficient. In practical applications, when lifting the battery pack, the gantry crane first moves the lifting device directly above the battery pack and lowers it onto the rectangular docking frame of the battery pack. Then, the front and rear rotary drive devices rotate the hanging plates 93 of the four hook assemblies 9 to the underside of the side beams of the rectangular docking frame, thus connecting the lifting device to the battery pack. Next, the gantry crane moves the battery pack to the vehicle chassis or charging position, and the front and rear rotary drive devices rotate the hanging plates 93 of the four hook assemblies 9 to the underside of the support frame 8, thus disconnecting the lifting device from the battery pack. Compared with existing technologies, this invention only requires controlling the front and rear rotary drive devices to connect or disconnect the lifting device from the battery pack, improving ease of operation, automation, and work efficiency. This invention employs a lifting mechanism consisting of a lifting reducer 4, fixed pulleys 5, and steel wire ropes 6. The lifting device is connected to four steel wire ropes 6 via four movable pulleys 7. During the rotation of the rope winding wheel 41 driven by the lifting reducer 4, the four steel wire ropes 6 maintain synchronous lifting, improving operational stability. Furthermore, the cooperation between the steel wire ropes 6 and the fixed and movable pulleys 5 and 7 effectively reduces wear, extends service life, and enhances safety and reliability. The lifting device is equipped with movable pulleys 7, a support frame 8, and four hook assemblies 9, which, in conjunction with the rectangular docking frame of the battery pack, ensures stable and reliable connection. It should be noted that the battery pack consists of a mounting frame and multiple battery sets fixed to the mounting frame. The rectangular docking frame is located on top of the mounting frame; its structure is well-known to those skilled in the art and will not be described further here. In practical applications, in order to maintain synchronous lifting, the four wire ropes 6 should be wound in different ways. In this invention, the two front wire ropes 6 are usually wound around the winding wheel 41 from the bottom, while the two rear wire ropes 6 are wound around the winding wheel 41 from the top. In order to ensure the stability of the structure and support, this invention also provides a bearing seat installed on the transverse frame 3 at the end of the winding wheel 41.

[0032] In a specific embodiment, the present invention mounts guide rollers 94 on the swing arm 92 of the hook assembly 9 via a support shaft, and the front and rear rotation drive devices adopt the following structure: the front rotation drive device is provided with a front electric push rod 95 hinged at one end to the support frame 8, and a front slide plate 96 that slides in the front-to-back direction and is slidably engaged with the support frame 8 at the other end of the front electric push rod 95. A front elongated hole 961 along the left-to-right direction is provided at the left and right ends of the front slide plate 96, so that the guide rollers 94 of the two front hook assemblies 9 are correspondingly located in the front elongated hole 961 at both ends of the front slide plate 96; the rear rotation drive device is provided with a rear electric push rod 97 hinged at one end to the support frame 8, and a rear slide plate 98 that slides in the front-to-back direction and is slidably engaged with the support frame 8 at the other end of the rear electric push rod 97. A rear elongated hole 981 along the left-to-right direction is provided at the left and right ends of the rear slide plate 98, so that the guide rollers 94 of the two rear hook assemblies 9 are correspondingly located in the rear elongated hole 981 at both ends of the rear slide plate 98. This setup simply requires the front electric push rod 95 and the rear electric push rod 97 to drive the front sliding plate 96 and the rear sliding plate 98 to slide in the front-rear direction, causing the guide rollers 94 of the front and rear hook assemblies 9 to roll in the front elongated holes 961 and 981 respectively, and correspondingly causing the hanging plates 93 of the front and rear hook assemblies 9 to rotate, thereby connecting or disconnecting the lifting device from the battery pack. It features a simple structure, convenient control, strong adaptability, and smooth operation. To improve the convenience of installation and operation, this specific embodiment provides mounting seats 99 on the support frame 8, which are respectively hinged to the front electric push rod 95 and the rear electric push rod 97, and the front electric push rod 95 and the rear electric push rod 97 are hinged to the middle of the front sliding plate 96 and the rear sliding plate 98 respectively, to improve the stability of the structure and operation. As a specific structure for sliding engagement, the present invention fixes a front slider 962 and a rear slider 982 to the bottom of the front slide plate 96 and the rear slide plate 98, respectively, and fixes a front guide rail 963 and a rear guide rail 983, respectively, to the support frame 8 to engage with the front slider 962 and the rear slider 982. However, it should be noted that the structure of sliding engagement between the front slide plate 96 and the rear slide plate 98 and the support frame 8 is not limited to the forms listed above, and other structural forms can also be adopted to achieve the technical objectives of the present invention.

[0033] As an optimization, this specific embodiment fixes four transverse guide columns 81 and two longitudinal guide columns 82 on the lower side of the support frame 8, and both the transverse guide columns 81 and the longitudinal guide columns 82 adopt a square structure. The lower end of the transverse guide column 81 has an inward-sloping, outward-sloping surface in the left-right direction, while the lower end of the longitudinal guide column 82 has an inward-sloping, outward-sloping surface in the front-back direction. This structure guides and positions the lifting device in the left-right direction through the four transverse guide columns 81, and guides and positions the lifting device in the front-back direction through the two longitudinal guide columns 82, improving the convenience and accuracy of docking with the battery pack. The left and right side beams of the rectangular docking frame of the battery pack serve as limiting members that cooperate with the transverse guide columns 81, and the two horizontal beams between the left and right side beams serve as limiting members that cooperate with the longitudinal guide columns 82. To avoid hard collisions and improve protection, this embodiment fixes a transverse protective plate 811 to the inclined surface and outer side of the transverse guide post 81, and a longitudinal protective plate 821 to the inclined surface and inner side of the longitudinal guide post 82. Both the transverse protective plate 811 and the longitudinal protective plate 821 are made of composite rubber sheet. It should be noted that for the transverse guide post 81, the inner side refers to the position between the four transverse guide posts 81 in the left-right direction, and the outer side refers to the position outside the four transverse guide posts 81 in the left-right direction. For the longitudinal guide post 82, the inner side is between the two longitudinal guide posts 82, and the outer side is outside the two longitudinal guide posts 82. As an optimization, this embodiment installs limiting screws 84 on the front and rear sides of the front slide plate 96 and the front and rear sides of the rear slide plate 98 respectively through supports 83 fixed to the support frame 8 to precisely control the rotation angle and position of the hanging plate 93. A cable reel 85 is fixed to the support frame 8, with a cable hole at the lower end of the reel 85. Terminal blocks 86, fixed to the support frame 8, are located on the left and right sides of the reel 85. In practical applications, the connecting cable between the gantry crane and the lifting device is placed in the reel 85 and connected to the terminal blocks 86 through the cable hole. This allows the reel 85 to automatically support the connecting cable during lifting, effectively preventing the cable from becoming tangled or twisted, and improving the stability and reliability of the electrical connection.

[0034] In a specific implementation, to facilitate longitudinal movement control, the present invention installs four longitudinal movement rollers 22 on the longitudinal movement frame 2, which cooperate with the longitudinal guide rail 1, and fixes a longitudinal movement reducer 23 on the longitudinal movement frame 2. The input shaft of the longitudinal movement reducer 23 is connected to a longitudinal movement drive motor (not shown in the figure), and both ends of the output shaft of the longitudinal movement reducer 23 are connected to two symmetrically distributed longitudinal movement rollers 22 via couplings 24. This configuration is simple in structure and easy to operate; simply driving the two longitudinal movement rollers 22 to rotate via the longitudinal movement reducer 23 allows the longitudinal movement frame 2 to move along the longitudinal guide rail 1. Similarly, to facilitate lateral movement control, the present invention installs four lateral rollers 31 on the lateral frame 3, which cooperate with the lateral guide rail 21. A drive shaft 32 is set between two symmetrically distributed lateral rollers 31, and a driven gear 33 is set on the drive shaft 32. A lateral reducer 34 is fixed on the lateral frame 3. The input shaft of the lateral reducer 34 is connected to a lateral drive motor (not shown in the figure), and the output shaft of the lateral reducer 34 is equipped with a driving gear 35. A transmission chain 36 is set between the driving gear 35 and the driven gear 33. This arrangement also has the characteristics of simple structure and convenient operation. The lateral frame 3 can be moved along the lateral guide rail 21 simply by driving the two lateral rollers 31 to rotate through the lateral reducer 34.

[0035] As an optimized solution, this specific embodiment uses steel rails for the longitudinal guide rail 1 and steel rail wheels for the longitudinal transfer rollers 22. The rims of the longitudinal transfer rollers 22 are positioned on the outer side of the longitudinal guide rail 1. Longitudinal anti-detachment plates 25, corresponding to the four longitudinal transfer rollers 22, are fixed to the longitudinal frame 2, with the hooks of the anti-detachment plates 25 positioned on the lower inner side of the rail head of the longitudinal guide rail 1. This structural arrangement, through the cooperation of the anti-detachment plates 25 and the rims of the longitudinal transfer rollers 22, effectively prevents the longitudinal transfer rollers 22 from detaching from the longitudinal guide rail 1, ensuring the safety and reliability of longitudinal movement. Similarly, in this specific embodiment, a pad 26 is fixed between the transverse guide rail 21 and the longitudinal moving frame 2, so that the transverse roller 31 adopts a steel rail wheel, with the rim of the transverse roller 31 located on the outer side of the transverse guide rail 21. A transverse anti-detachment plate 37 corresponding to the four transverse rollers 31 is fixed on the transverse moving frame 3, with the hook of the anti-detachment plate 37 located on the inner lower side of the pad 26. This structural arrangement, through the cooperation of the anti-detachment plate 37 with the rim of the transverse roller 31, effectively prevents the transverse roller 31 from falling off the transverse guide rail 21, ensuring the safety and reliability of transverse movement. It should be noted that, for the longitudinal guide rail 1, the area between the two longitudinal guide rails 1 is the inner side, and the area outside the two longitudinal guide rails 1 is the outer side; for the transverse guide rail 21 and the pad 26, the area between the two transverse guide rails 21 is the inner side, and the area outside the two transverse guide rails 21 is the outer side. As an optimized solution, this specific embodiment employs the following installation method for the transverse reducer 34: An adapter plate 341 is fixed to the transverse reducer 34. Multiple elongated adjustment holes 342, perpendicular in length to the drive shaft 32, are provided on the adapter plate 341. The adapter plate 341 is mounted on the transverse frame 3 via multiple connecting bolts corresponding to the elongated adjustment holes 342. A tensioning block 343 is fixed to the transverse frame 3 on one side of the adapter plate 341 along the length of the elongated adjustment holes 342. Two or more tensioning bolts 344, which press against the adapter plate 341, are installed on the tensioning block 343 via threaded holes. This structural configuration only requires loosening the connecting bolts in the elongated adjustment holes 342 and pressing the adapter plate 341 against it by rotating the tensioning bolts 344 to adjust the tension of the drive chain 36. After tensioning, the connecting bolts are tightened again to fix the adapter plate 341 and the transverse reducer 34. This design features a simple structure and convenient tension adjustment.

[0036] In a specific embodiment, the present invention mounts a fixed pulley 5 onto a transverse frame 3 via a first pulley frame 51, and first rope-blocking plates 52 are fixed on both sides of the first pulley frame 51, with a rope-blocking rod 53 positioned between the first rope-blocking plates 52. By setting the first rope-blocking plates 52 and the rope-blocking rod 53, the wire rope 6 can be effectively prevented from slipping off the fixed pulley 5, improving safety and reliability. Similarly, the present invention mounts a movable pulley 7 onto a support frame 8 via a second pulley frame 71, and second rope-blocking plates 72 are fixed on both sides of the second pulley frame 71, with a rope-blocking roller 73 installed between the second rope-blocking plates 72 via a pin. By setting the second rope-blocking plates 72 and the rope-blocking roller 73, the wire rope 6 can be effectively prevented from slipping off the movable pulley 7, improving safety and reliability. To ensure the wire rope 6 winds sequentially onto the winding wheel 41 during lifting and lowering to avoid overlap, this embodiment installs an upper pressure rope roller 43 on the lifting reducer 4 via a bracket plate 42, and a lower pressure rope roller 44 on the transverse frame 3, ensuring the smoothness of the lifting and lowering operation. The upper pressure rope roller 43 acts on the wire rope 6 wound from the top, while the lower pressure rope roller 44 acts on the wire rope 6 wound from the bottom. In practical applications, the invention also fixes positioning cylinders 38 spaced apart at the front and rear on the lower side of the transverse frame 3, and the lower end of the positioning cylinders 38 adopts a trumpet-shaped structure. Correspondingly, a positioning post 87 cooperating with the positioning cylinder 38 is fixed on the upper side of the support frame 8, a limiting sleeve 871 is fitted onto the lower half of the positioning post 87, and the upper end of the positioning post 87 adopts a conical structure. When lifting the lifting device and battery pack, the positioning column 87 is inserted into the positioning cylinder 38 to keep the transverse frame 3 and the lifting device relatively fixed, which can effectively prevent swaying during the movement and improve the stability and safety of the lifting.
