[0024] The following gives specific embodiments.

[0025] Please refer to Figure 1 and Figure 2As shown in the figure, an automated port loading and unloading towing device according to an embodiment of the present utility model includes a main body 1; two electric push rods 12 are symmetrically installed inside the main body 1; an output end of the electric push rod 12 is fixedly connected to a sliding plate 13; the sliding plate 13 is slidably connected to the main body 1; a top rod 14 is fixedly connected to the middle of the sliding plate 13; an end of the top rod 14 is fixedly connected to a second connecting plate 151; two connecting rods 16 are symmetrically hinged to the middle of the sliding plate 13; an end of the connecting rod 16 is hinged to a first connecting plate 15; a telescopic rod 19 is fixedly connected to the middle of the first connecting plate 15; the telescopic rod 19 is fixedly connected to the main body 1; guiding plates 17 are fixedly connected to the tops of the first connecting plate 15 and the second connecting plate 151; the guiding plates 17 are of an arc structure; a plurality of rotating wheels 18 are rotatably connected to the middle of the guiding plates 17; during operation, the main body 1 will reach the position for carrying the container according to the system settings, and then the spreader will send the container to the top of the device. During the descent of the container, the device will be started. After the device is started, it will drive the electric push rod 12 to start. After the electric push rod 12 starts, it will drive the sliding plate 13 to slide along the main body 1 and move closer to the electric push rod 12. When the sliding plate 13 moves, it will drive the top rod 14 to move together. When the top rod 14 moves, it will drive the second connecting plate 151 to move together and move closer to the main body 1. When the sliding plate 13 moves, it will also change the angle of the connecting rod 16. When the angle of the connecting rod 16 changes, it will also make the first connecting plate 15 move closer to the main body 1. When the first connecting plate 15 moves, it will change the length of the telescopic rod 19. When the first connecting plate 15 and the second connecting plate 151 move, they will drive the guiding plate 17 to move together. When the guiding plate 17 moves to a suitable position, the electric push rod 12 will stop working. At this time, during the descent of the container, it will come into contact with the guiding plate 17 and slide along the surface of the guiding plate 17. The container will also come into contact with the rotating wheels 18 on the surface of the guiding plate 17 and cause the rotating wheels 18 to rotate. Subsequently, the container will slide along the surface of the guiding plate 17 under the rolling friction of the rotating wheels 18. Finally, the container will land on the top of the main body 1 and be carried by the main body 1; through the combined action of the guiding plate 17 and the rotating wheels 18, during the descent of the container, it will slide along the surface of the guiding plate 17 and have rolling friction with the rotating wheels 18, realizing the guiding effect of the device on the descent path of the container, ensuring that the container can be accurately placed on the surface of the main body 1, improving the convenience of the device for loading and unloading the container, reducing the time required for alignment during the hoisting of the container.

[0026] Please refer to Figure 3As shown, a plurality of first springs 2 are fixedly connected to the middle of the first connecting plate 15 and the second connecting plate 151; the ends of adjacent first springs 2 are fixedly connected to vertical plates 22; after the container slides down along the guiding plate 17 to the surface of the body 1, the container will come into contact with the vertical plate 22 and exert pressure on the vertical plate 22. After the vertical plate 22 is subjected to the pressure, it will transmit the pressure to the first spring 2. After the first spring 2 is subjected to the pressure, it will contract. Subsequently, the first spring 2 will release its elastic potential energy and exert an elastic force on the vertical plate 22, and the vertical plate 22 will squeeze the side wall of the container to assist the body 1 in fixing the container; through the cooperative action of the first spring 2 and the vertical plate 22, the vertical plate 22 will squeeze the side wall of the container under the elastic force of the first spring 2, increasing the contact area between the device and the container, reducing the shaking of the container during transportation, and improving the stability of the device when transporting the container.

[0027] Please refer to Figure 3 As shown, a plurality of suction cups 3 are fixedly connected to the middle of the vertical plate 22; the suction cups 3 are arranged in an array; when the container comes into contact with the vertical plate 22, it will also come into contact with the suction cups 3 and squeeze the suction cups 3. After the suction cups 3 are squeezed, they will discharge the air inside, and then will adsorb the surface of the container under the action of atmospheric pressure; by providing the suction cups 3, when the suction cups 3 are squeezed by the container, they will adsorb the container, further increasing the contact area between the device and the container and enhancing the fixing effect of the device on the container.

[0028] Please refer to Figure 3 and Figure 4 As shown, a plurality of second springs 42 are fixedly connected to the middle of the vertical plate 22; the ends of adjacent second springs 42 are fixedly connected to a pressure ring 4; the pressure ring 4 is arranged corresponding to the suction cups 3; after the container comes into contact with the suction cups 3, it will continue to come into contact with the pressure ring 4 and squeeze the pressure ring 4. After the pressure ring 4 is subjected to the pressure, it will transmit the pressure to the second spring 42. After the second spring 42 is subjected to the pressure, it will be in a compressed state and release its elastic potential energy to drive the pressure ring 4 to squeeze the middle of the suction cups 3, reducing the external air entering the suction cups 3; through the cooperative action of the pressure ring 4 and the second spring 42, after the container squeezes the pressure ring 4, the pressure ring 4 will be subjected to the elastic force of the second spring 42 and squeeze the middle of the suction cups 3, reducing the interference of external air on the suction cups 3, improving the airtightness of the suction cups 3, and enhancing the adsorption effect of the suction cups 3 on the container.

[0029] Please refer to Figure 3 and Figure 4As shown, a plurality of rubber pads 5 are fixedly connected to the middle of the vertical plate 22; the surface of the rubber pad 5 is an arc structure; when the container comes into contact with the vertical plate 22, it will also come into contact with the rubber pad 5. Because the surface friction coefficient of the rubber pad 5 is larger, the friction force between the device and the container is increased; by providing the rubber pad 5, when the container comes into contact with the vertical plate 22, it will also come into contact with the rubber pad 5, increasing the friction force between the device and the container, and further enhancing the fixing effect of the device on the container.

[0030] Please refer to Figure 4 As shown, air bags 62 are fixedly connected to the middle of the first connecting plate 15 and the second connecting plate 151; a plurality of second round holes 63 are formed in the middle of the air bag 62; a plurality of first round holes 6 are formed in the middle of the vertical plate 22; when the container presses on the vertical plate 22, the first spring 2 will be in a contracted state, and the vertical plate 22 will move closer to the first connecting plate 15 and the second connecting plate 151 and come into contact with the air bag 62. After the air bag 62 is squeezed, the air inside will be ejected from the second round holes 63 and pass through the first round holes 6 to reach the side of the container. Under the action of the air flow, the dust on the side of the container will be removed; when the air bag 62 is squeezed by the vertical plate 22, the air inside will be ejected and reach the surface of the container, realizing the cleaning of the container by the device and reducing the dust attached to the surface of the container.

[0031] Please refer to Figure 4 As shown, a drying box 7 is fixedly connected to the inner wall of the air bag 62; the four corners of the drying box 7 are arc-shaped transitions; desiccants are placed in the drying box 7, so that the air inside the air bag 62 can always be kept dry. The dry air will be more likely to remove the dust and impurities attached to the surface of the container; by providing the drying box 7, the drying box 7 will dry the air inside the air bag 62, reducing the moisture inside the air bag 62, so that the air ejected from the air bag 62 can better clean the surface of the container.

[0032] Working principle: The main body 1 will reach the position of the loaded container according to the system settings. Subsequently, the spreader will send the container to the top of the device. During the descent of the container, the device will start. After starting, the device will drive the electric push rod 12 to start. After the electric push rod 12 starts, it will drive the slide plate 13 to slide along the main body 1 and approach the electric push rod 12. When the slide plate 13 moves, it will drive the ejector rod 14 to move together. When the ejector rod 14 moves, it will drive the second connecting plate 151 to move together and approach the main body 1. When the slide plate 13 moves, it will also change the angle of the connecting rod 16. When the angle of the connecting rod 16 changes, it will also make the first connecting plate 15 approach the main body 1. When the first connecting plate 15 moves, it will change the length of the telescopic rod 19. When the first connecting plate 15 and the second connecting plate 151 move, they will drive the guide plate 17 to move together. When the guide plate 17 moves to a suitable position, the electric push rod 12 will stop working. At this time, during the fall of the container, it will come into contact with the guide plate 17 and slide along the surface of the guide plate 17. The container will also come into contact with the runner 18 on the surface of the guide plate 17 and cause the runner 18 to rotate. Subsequently, the container will slide along the surface of the guide plate 17 under the rolling friction of the runner 18. Finally, the container will land on the top of the main body 1 and be carried by the main body 1; after the container slides down along the guide plate 17 to the surface of the main body 1, the container will come into contact with the vertical plate 22 and exert pressure on the vertical plate 22. After the vertical plate 22 is subjected to the pressure, it will transfer the pressure to the first spring 2. After the first spring 2 is subjected to the pressure, it will contract. Subsequently, the first spring 2 will release its elastic potential energy and exert an elastic force on the vertical plate 22. The vertical plate 22 will squeeze the side wall of the container to assist the main body 1 in fixing the container; when the container comes into contact with the vertical plate 22, it will also come into contact with the suction cup 3 and squeeze the suction cup 3. After the suction cup 3 is squeezed, it will discharge the air inside. Subsequently, it will adsorb the surface of the container under the action of atmospheric pressure; after the container comes into contact with the suction cup 3, it will continue to come into contact with the compression ring 4 and squeeze the compression ring 4. After the compression ring 4 is subjected to the pressure, it will transfer the pressure to the second spring 42. After the second spring 42 is subjected to the pressure, it will be in a compressed state and release its elastic potential energy to drive the compression ring 4 to squeeze the middle of the suction cup 3, reducing the external air entering the suction cup 3; when the container comes into contact with the vertical plate 22, it will also come into contact with the rubber pad 5. Because the surface friction coefficient of the rubber pad 5 is larger, it increases the friction between the device and the container; when the container squeezes the vertical plate 22, the first spring 2 will be in a contracted state, and the vertical plate 22 will approach the first connecting plate 15 or the second connecting plate 151 and come into contact with the airbag 62. After the airbag 62 is squeezed, the air inside will be ejected from the second round hole 63 and pass through the first round hole 6 to reach the side of the container. Under the action of the air flow, the dust on the side of the container will be removed; a desiccant is placed in the drying box 7, so that the air inside the airbag 62 can always be kept dry. The dry air will be more likely to remove the dust and impurities attached to the surface of the container.
