[0004] This utility model provides a telescopic gantry crane for a battery swapping station.

[0005] The technical solution of this utility model is implemented as follows: A telescopic gantry crane for a battery swapping station includes two spaced-apart large frames. Two spaced-apart columns are fixedly connected to the top of each large frame. A synchronous drive device is installed between the two large frames. Crossbeams are fixedly connected to the upper sides of the two opposing columns. Two bidirectional three-stage telescopic forks are installed on the top of the two opposing crossbeams. The bottom fork of the bidirectional three-stage telescopic fork is fixed to the top of the crossbeam. A horizontal moving device is fixedly connected to the top of the top fork of each bidirectional three-stage telescopic fork. The horizontal moving device includes two trolley tracks, which are fixedly connected to the top of the top fork of the bidirectional three-stage telescopic fork. A trolley frame travels within the trolley tracks. A drum is installed on the trolley frame, and a wire rope is wound on the drum. The tail of the wire rope is mounted on a fixed pulley, which is connected to a lifting device.

[0006] The longitudinal section of the trolley track is an inverted U-shaped structure. There are two traveling wheels on both sides of the trolley frame. The traveling wheels travel in the groove of the trolley track. A horizontally arranged drive motor is installed at the end of the trolley frame.

[0017] like Figure 1-5As shown, a telescopic gantry crane for a battery swapping station includes two spaced-apart trolley frames 1. Each trolley frame 1 has two spaced-apart columns 2 fixedly connected to its top. A synchronous drive device is installed between the two trolley frames 1. Crossbeams are fixedly connected to the upper sides of the two opposing columns 2. Two bidirectional three-stage telescopic forks 3 are mounted on the top of the opposing crossbeams. The bottom forks of the bidirectional three-stage telescopic forks 3 are fixed to the top of the crossbeams. A horizontal moving device is fixedly connected to the top of the top forks of the two bidirectional three-stage telescopic forks 3. The horizontal moving device includes two trolley tracks 4, which are fixedly connected to the top of the top forks of the bidirectional three-stage telescopic forks 3. A trolley frame 5 travels within the trolley tracks 4. A drum 6 is installed on the trolley frame 5, and a wire rope is wound on the drum 6. The wire rope is not shown in the figure; this is prior art and will not be described further. The tail of the wire rope is mounted on a fixed pulley 25, which is connected to a lifting device 7.

[0018] Specifically, the main frame 1 moves back and forth along the track, the drum 6 drives the spreader 7 to lift and lower, the spreader 7 lifts the battery pack 26, and the two-way three-stage telescopic fork 3 adopts the two-way three-stage telescopic fork 3 sold on the market, such as those sold by McDonnell Douglas, or other companies' products are not limited. When the vehicle is on the left or right side of the track, the two-way three-stage telescopic fork 3 is activated. The bottom fork of the two-way three-stage telescopic fork 3 is fixed, while the middle fork and top fork can move left and right. When it moves to the left or right side of the track, the two-way three-stage telescopic fork 3 drives the trolley traveling mechanism to move, and the trolley traveling mechanism drives the spreader 7 to adjust left and right.

[0019] The longitudinal section of the trolley track 4 is an inverted U-shaped structure. The two sides of the trolley frame 5 are provided with traveling wheels 8, which travel in the groove of the trolley track 4. The end of the trolley frame 5 is equipped with a horizontally arranged drive motor 9. The shaft of the drive motor 9 is equipped with a drive gear 10, which meshes with a rack 11. The rack 11 is fixedly connected to the top of one of the trolley tracks 4.

[0020] Specifically, the lifting device 7 suspends the battery on the left or right side of the track. If a slight movement of the left or right distance is required, the drive motor 9 is started, the drive gear 10 moves along the rack 11, and drives the traveling wheel 8 to move on the trolley track 4, thereby achieving fine adjustment of the left and right distance and more accurate positioning.

[0021] The synchronous drive device includes two connecting beams 12, which are fixedly connected between two opposing columns 2. A horizontally arranged drive motor 13 is installed on the side of one of the connecting beams 12. The drive motor 13 is connected to a reduction gearbox. Connecting shafts 14 are rotatably arranged at both ends of the reduction gearbox. A drive sprocket 15 is fixedly connected to the end of the connecting shaft 14. A driven sprocket 16 is connected to the drive sprocket 15 through a chain. The driven sprocket 16 is installed on the extension of the axle of the adjacent travel wheel 17. The driven sprocket 16 is located outside the main frame 1.

[0022] Specifically, the drive motor 13 starts, which drives the connecting shafts 14 at both ends to rotate. The drive sprocket 15 rotates and drives the driven sprocket 16 to rotate through the chain, causing the walking wheel 17 to rotate, thereby realizing the synchronous movement of the two large frames.

[0023] The lifting device includes a lifting frame 18. L-shaped hooks 19 are rotatably connected to the four corners of the bottom surface of the lifting frame 18. Each L-shaped hook 19 has a cam 20 mounted on its top end after passing through the lifting frame 18. A horizontally distributed linkage rod 21 is hinged between two cams 20 on the same side of the lifting frame 18. An electric push rod 22 is installed on one side of the linkage rod 21 on the lifting frame 18. The two ends of the electric push rod 22 are hinged to the lifting frame 18 and the linkage rod 21, respectively. Specifically, when the battery pack is below the lifting device 7, the drum 6 starts and lowers the lifting device 7 to its position, allowing all four L-shaped hooks 19 to be inside the battery pack 26. Then, when the free end of the electric push rod 22 extends, the linkage rod 21 and the cams 20 work together to rotate the two L-shaped hooks on the same side of the lifting frame 18 synchronously, causing the horizontal parts of the L-shaped hooks 19 to rotate to below the frame at the top of the battery pack 26, hooking the battery pack and thus lifting the battery pack 26.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
