[0027] like Figures 1-6As shown, a cantilever-type railway station container loading and unloading device includes a crane body 1, a cantilever 2 is movably connected to the crane body 1, the end of the cantilever 2 is rotatably connected to a rotating shaft 201, the bottom of the rotating shaft 201 is fixedly connected to a fixed block 301, the bottom of the fixed block 301 is slidably connected to a mounting plate 302, a slide groove is provided on the top of the mounting plate 302, the mounting plate 302 slides back and forth along the slide groove, and a first spring 303 for resetting is connected between the fixed block 301 and the slide groove.

[0028] The bottom of the mounting plate 302 is connected to a sling 7 through a mounting assembly. The sling 7 includes a hook head and a power assembly for driving the hook head to rotate. The power assembly adopts a brake motor, which directly drives the hook head to rotate. The four corners of the top of the container are fixedly connected to a cylinder with an open top. The inner wall of the cylinder is provided with a groove, and the bottom of the cylinder is provided with a circular card slot. After the hook head enters the card slot along the groove, the motor drives the hook head to rotate ninety degrees, so that the position of the hook head and the groove is staggered. At this time, the container can be lifted by the sling 7. The sling 7 adopts the existing technology, so it will not be described in detail. The installation component includes two vertical plates 601 connected to the bottom of the mounting plate 302 by bolts, a slide bar 602 is fixedly connected between the two vertical plates 601, and a moving block 603 is slidably connected to the slide bar 602. The sling 7 is fixedly connected to the bottom of the moving block 603, and a second spring 604 is connected between the moving block 603 and the vertical plate 601. The second spring 604 is wrapped around the outer periphery of the slide bar 602, and the sling 7 is slid left and right along the mounting plate 302 through the installation component.

[0029] A first adjustment component is provided in the mounting plate 302, and the left and right position of the sling 7 is fine-tuned by the first adjustment component. The first adjustment component includes a rotating motor 401, and the rotating motor 401 is bolted to one side of the mounting plate 302. The output end of the rotating motor 401 is connected to a first bidirectional screw rod 402 through a coupling. A first mounting groove is provided in the mounting plate 302, and the first bidirectional screw rod 402 is rotatably connected in the first mounting groove. Two first sliders 403 are threadedly connected to the first bidirectional screw rod 402, and the first slider 403 is slidably connected in the first mounting groove. The bottom of the first slider 403 is fixedly connected to a first limit plate 404, and the two first limit plates 404 are arranged on the left and right.

[0030] A second adjustment component is provided in the mounting plate 302, and the position of the spreader 7 in the front and rear directions is fine-tuned by the second adjustment component. The second adjustment component includes a stepping motor 501, and the stepping motor 501 is bolted to the rear side of the mounting plate 302. The output end of the stepping motor 501 is connected to the second bidirectional screw rod 502 through a coupling. A second mounting slot is provided in the mounting plate 302, and the second bidirectional screw rod 502 is rotatably connected in the second mounting slot. Two second sliders 503 are threadedly connected to the second bidirectional screw rod 502, and the second slider 503 is slidably connected in the second mounting slot. The bottom of the second slider 503 is fixedly connected to a second limit plate 504, and the two second limit plates 504 are arranged front and back. The lowest points of the first limit plate 404 and the second limit plate 504 are lower than the lowest point of the spreader 7, so that the first limit plate 404 and the second limit plate 504 can abut against the side wall of the container during the movement, and then push the spreader 7.

[0031] Working principle: When in use, the worker drives the crane body 1 in the cab. When lifting the container, first, by controlling the cantilever 2, the position of the spreader 7 and the container is basically coincident. At this time, by controlling the cantilever 2, the spreader 7 is lowered to a suitable height, and the rotating motor 401 is started. The rotating motor 401 drives the first bidirectional screw rod 402 to rotate, and the first bidirectional screw rod 402 drives the first slider 403 to drive the two first limit plates 404 to move synchronously in the direction of approaching each other. One of the first limit plates 404 first abuts against the side wall of the container. At this time, the two first limit plates 404 are in contact with the side wall of the container. The first limit plate 404 continues to move, pushing the spreader 7 toward the axis of the container. At this time, the moving block 603 drives the spreader 7 to move along the slide bar 602 until the two first limit plates 404 are in contact with the side walls of the container, thereby adjusting the left and right positions of the spreader 7. The stepper motor 501 is started, and the stepper motor 501 drives the second bidirectional screw rod 502 to rotate. The second bidirectional screw rod 502 drives the second slider 503 to drive the two second limit plates 504 to move synchronously in the direction of approaching each other. One of the second limit plates 504 first abuts against the container. At this time, the two second limit plates 504 are in contact with the container. The limit plate 504 continues to move, pushing the spreader 7 toward the axis of the container. At this time, the mounting plate 302 moves forward and backward along the fixing block 301 until the two second limit plates 504 are in contact with the side walls of the container, thereby adjusting the position of the spreader 7 in the front and rear directions, so that the hook head on the spreader 7 corresponds to the groove on the container. Then, by controlling the cantilever 2, the spreader 7 drives the hook head to move in the direction of the groove. After the hook head is inserted into the groove, the hook head is rotated 90 degrees. The direction of the hook head is perpendicular to the groove and the hook head cannot fall out of the groove. By manipulating the crane body 1 and the cantilever 2, the spreader 7 is moved When loading a container onto a train or unloading a container from a train, during the process of moving the container, the first limit plate 404 and the second limit plate 504 are kept in contact with the container, so that the first limit plate 404 and the second limit plate 504 provide a certain clamping force for the container, thereby improving the stability of the container movement process. After the container is placed at a certain position, the rotating motor 401 and the stepping motor 501 are reversed to reset the first limit plate 404 and the second limit plate 504. Then, the mounting plate 302 and the sling 7 are reset under the action of the first spring 303 and the second spring 604, respectively.
