[0029] Furthermore, a first rack is provided at the bottom of the first telescopic arm welding frame 422, and a first telescopic arm driving motor 47 for driving the first telescopic arm welding frame 422 to move is provided on the trolley welding frame 411, and a driving shaft of the first telescopic arm driving motor 47 is connected to a first gear, and the first gear is meshed with the first rack. The first telescopic arm driving motor 47 drives the first gear to rotate, and the first gear is meshed with the first rack, so that the first telescopic arm welding frame 422 moves along the trolley welding frame 411, realizes the telescopic action of the first telescopic arm 42, and ensures that the moving position of the first telescopic arm 42 is accurate, thereby improving the transmission efficiency and reducing the energy loss.

Through the action of the push rod system 459, the rotation of the hook 457 is controlled to realize the transportation of the battery.

[0035] By providing the upper welding frame 451 of the hoist, the lower welding frame 452 of the hoist, the rotating drive mechanism, the push rod system and the hook, the rotatable function of the hoist is realized, which can effectively reduce the accuracy requirement for the parking position of the new energy heavy-duty truck 5. At the same time, by adjusting the angle of the hoist, the requirement for the parking position is reduced, making the layout of the battery swap station more flexible and adaptable to different site conditions, thereby expanding the application scope of the battery swap station and better serving the battery swap needs of electric heavy-duty trucks.

[0036] The rotary drive mechanism includes a pinion 454, a slewing bearing 455 and a motor 4511. The motor 4511 is arranged on the lower welded frame 452 of the spreader. The output shaft of the motor 4511 is connected to the pinion 454. The slewing bearing 455 is fixedly connected to the lower welded frame 452 of the spreader through the lower mounting plate 4510 of the slewing bearing. The pinion 454 drives the slewing bearing 455 to rotate. The motor 4511 drives the pinion 454 to rotate, and the rotation of the pinion 454 drives the slewing bearing 455 to rotate, thereby driving the lower welded frame 452 of the spreader to rotate. This design realizes the precise rotation control of the spreader, ensuring that the spreader can be accurately adjusted to the required angle.

[0037] like Fig.11 As shown, the outer circle of the slewing support bearing 455 is arranged on the lower mounting plate 4510 of the slewing support bearing; the inner circle of the slewing support bearing 455 is connected to the welding frame 451 on the hanger, and the inner circle is meshed with the pinion 454; the outer circle is arranged on the lower mounting plate 4510 of the slewing support bearing to provide outer support, and the inner circle is meshed with the pinion 454, and the pinion 454 drives the inner circle to rotate, thereby driving the welding frame 452 under the hanger to rotate; In this embodiment, a guide cone 453 on the sling is provided above the welding frame 451 on the sling, which is used to guide the sling to be accurately aligned with the trolley 44. The guide cone 453 on the sling is aligned with the guide cylinder 446 on the trolley 44, ensuring the accurate docking of the sling with the heavy truck battery.

[0038] Furthermore, the guide cone 453 on the sling is fixed to the upper side of the sling upper welding frame 451 through the guide cone mounting plate 456 on the sling. The design of the guide cone mounting plate 456 on the sling can provide a stable mounting platform to ensure the stable installation of the guide cone 453 on the sling upper welding frame 451. In this embodiment, the guide cone mounting plate 456 on the sling is fixed to the upper side of the sling upper welding frame 451 by bolts to ensure its stability during operation.

[0039] A lower inclined guide cone 458 of the sling is provided below the lower welding frame 452 of the sling, and the lower inclined guide cone of the sling is used to interactively guide the battery and guide the sling to fit the battery.

The electric push rod 45901 is mounted on the lower welding frame 452 of the sling through the electric push rod mounting plate 45905. The electric push rod 45901 is connected to the connecting plate 45902. The cam 45904 is rotatably arranged on the connecting plate 45902. The hook 457 is connected to the cam 45904 and locked by the pressing plate 45903. The telescopic action of the electric push rod 45901 drives the connecting plate 45902 and the cam 45904 to rotate, thereby controlling the rotation of the hook 457 to achieve the capture and release of the battery. The connecting plate 45902 is connected to the electric push rod 45901, and the cam 45904 is rotatably set on the connecting plate 45902, and the movement of the connecting plate 45902 drives the cam 45904 to rotate; the linear motion of the electric push rod 45901 is converted into the rotational motion of the cam 45904, and the hook 457 is connected to the cam 45904, and the rotation of the hook 457 is achieved by the rotation of the cam 45904, so as to capture and release the battery. When the hook 457 is working, the pressure plate 45903 locks the hook 457 to ensure the stability of the hook 7 during the working process and prevent the hook 457 from loosening.

[0041] The electric push rod mounting plate 45905 is connected to the electric push rod 45901 through a pin shaft and a cotter pin.

[0042] The electric push rod 45901 is connected to the connecting plate 45902 via a pin shaft and a cotter pin. The pin shaft connects the electric push rod 45901 and the connecting plate 45902 together, providing a stable connection point, and the cotter pin prevents the pin shaft from loosening or falling off during operation, so that the telescopic action of the electric push rod 45901 can be stably transmitted to the connecting plate 45902, driving the rotation of the connecting plate 45902 and the cam 45904, and realizing precise control of the hook 457.

[0043] The connecting plate 902 is connected to the cam 45904 through a pin shaft and a cotter pin. The connecting plate and the cam are connected together through the pin shaft, providing a stable connection point, and the cotter pin prevents the pin shaft from loosening or falling off during operation, ensuring the reliability of the connection, so that the movement of the connecting plate 45902 can be stably transmitted to the cam 45904, driving the cam 45904 to rotate, and realizing precise control of the hook 457.

[0044] Based on the rotatable hanger of the heavy truck swap station in the above embodiment, the specific installation process is as follows: The lower mounting plate 4510 of the slewing bearing is welded to the lower welding frame 452 of the lifting device, and then the outer circle of the slewing bearing 455 is mounted on the lower mounting plate 4510 of the slewing bearing and screwed in; then the upper welding frame 451 of the lifting device is connected to the inner circle and screwed in; The motor 4511 is installed on the welding frame 452 under the sling and locked on it. The motor 4511 is connected to the pinion 454, and the pinion 454 is meshed with the inner circle. In this way, when the motor 4511 drives the pinion 454 to rotate, the pinion 454 will drive the inner circle to rotate. Since the outer circle is connected to the welding frame 452 under the sling and the inner circle is connected to the welding frame 451 on the sling, only the inner circle rotates at this time, which will drive the welding frame 451 on the sling to rotate together. However, the welding frame 451 on the sling is connected to the trolley 44, so the welding frame 451 on the sling cannot rotate. In this way, the outer circle will be subjected to a reverse force, which will cause the outer circle to rotate in the opposite direction to the rotation direction of the pinion 454. The outer circle and the welding frame 452 under the sling are connected together, so the welding frame 452 under the sling will rotate, so that the rotation of the sling can be realized.

[0045] The guide cone mounting plate 456 on the sling is welded to the welding frame 451 on the sling, and the guide cone 453 on the sling is locked to the guide cone mounting plate 456 on the sling; the push rod system 459 is installed together with the hook 457, and is used to control the rotation of the hook 457 to complete the transportation of the battery; the electric push rod mounting plate 45905 is locked on the welding frame 452 under the sling, and is connected to the electric push rod 45901 through a pin shaft and a cotter pin; the electric push rod 45901 is connected to the connecting plate 45902 through a pin shaft and a cotter pin, and the connecting plate 45902 is connected to the cam 45904 through a pin shaft and a cotter pin, and the hook 457 is connected to the cam 45904, and there is a step in the middle of the cam 45904 for restriction, and the pressure plate 45903 is locked on the hook 457 to restrict the hook 457, so that the hook 457 can only rotate with the cam 45904.

[0046] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the protection scope of the invention.
