[0022] Among them, the flipping component 7 includes a rotating motor 71, the output end of the rotating motor 71 is connected to a connecting shaft 72, a clamping block 73 is arranged outside the connecting shaft 72, a clamping groove 74 is opened inside the connecting block 61, and a distance measuring sensor 75 is arranged at the bottom of the connecting frame 5

[0023] Please refer to Figures 1-4, There are two sets of support frames 1 and transverse brackets 2, which are symmetrically distributed. A driving motor and a driving wheel are arranged between the moving component 3 and the transverse bracket 2. The chain electric hoist 4 is fixedly connected to the moving component 3. The chain end of the chain electric hoist 4 is connected to the connecting frame 5. The auxiliary plate 51 is fixedly connected to the connecting frame 5, which is conducive to the rotational connection between the auxiliary plate 51 and the connecting block 61.

[0024] Please refer to Figures 1-4 , The hook 6 is fixedly connected to the connecting block 61. The connecting block 61 and the auxiliary plate 51 are connected by a flipping component 7. The infrared emission component 8 includes an infrared emitter one 81 and an infrared emitter two 82. The infrared receiving component 9 includes an infrared receiver one 91 and an infrared receiver two 92, which is conducive to detecting whether the formed distances of the two sets of support frames 1 are synchronized and avoiding large deviations in the walking of the two sets of support frames 1 during the slipping of the walking wheels 11.

[0025] Please refer to Figures 1-4 , The output end of the walking motor 10 is fixedly connected to the walking wheel 11. The CCD camera 12 is fixedly connected to the moving component 3. The CCD camera 12 is electrically connected to an external controller, which is conducive to monitoring the height of the hook 6 descending and whether the connection between the hook 6 and the lifting object is successful.

[0026] Please refer to Figures 1-4 , The rotating motor 71 is fixedly connected to the auxiliary plate 51 by bolts. The rotating motor 71 is electrically connected to an external controller. The output end of the rotating motor 71 is fixedly connected to the connecting shaft 72. The connecting shaft 72 is rotatably connected to the auxiliary plate 51.

When the connecting frame 5 descends to contact the top of the item to be lifted, control the hook 6 to flip to hook the lifting item, so as to facilitate its automatic connection without manual operation.

[0027] Working principle of the utility model: During the use of the device, the traveling motor 10 drives the traveling wheels 11 to travel, further driving the two sets of support frames 1 to move. The CCD camera 12 is used to identify whether it reaches above the item to be lifted. Then, the moving component 3 moves through the driving motor and the driving wheels, moving the chain electric hoist 4 to directly above the item to be lifted. Then, the connecting frame 5 is driven to descend, and the turning component 7 drives the connecting block 61 and the hook 6 to turn until the connecting frame 5 contacts above the item to be lifted. Then, the turning component 7 is controlled to drive the connecting block 61 and the hook 6 to reset, and further rotate inside the lifting rope of the item to be lifted, bringing the lifting rope into contact with the inside of the hook 6, thus achieving the hanging effect. Finally, the chain electric hoist 4 drives the connecting frame 5, the hook 6, and the lifted item to rise for subsequent movement, eliminating the need for manual connection between the hook 6 and the lifting rope by workers.

[0028] It should be noted that with the setting of the turning component 7, when the hook 6 needs to turn, the output end of the rotating motor 71 drives the connecting shaft 72 to rotate along the inside of the auxiliary plate 51. At the same time, the connection between the connecting shaft 72 and the connecting block 61 through the clamping block 73 and the clamping groove 74 plays a fixing role, further driving the connecting block 61 to rotate. Also, because of the fixed connection between the connecting block 61 and the hook 6, the hook 6 is driven to rotate. During this process, the distance measuring sensor 75 monitors the rotation angle of the connecting block 61 in real time to determine whether the connecting block 61 has been successfully turned.

[0029] It should be noted that with the setting of the infrared emission component 8 and the infrared reception component 9, the infrared emitter 1 81 corresponds to the infrared receiver 1 91, and the infrared emitter 2 82 corresponds to the infrared receiver 2 92, thereby judging the traveling distance between the two sets of support frames 1, avoiding the problem of slipping and inability to detect during the traveling of the traveling wheels 11, and enabling better detection of whether the traveling between the two is synchronized.
