[0022] In this embodiment, through the cooperation of the first fixing plate 1, the second fixing plate 3, the first screw rod 2 and the first nut 4, the first screw rod 2 passing through the first fixing plate 1 and the second fixing plate 3 is conducive to fixing the device on the supporting square column of the building. Through the setting of the bearings 6, the number of which is two and are respectively located at the top and bottom of the fixed cylinder 5, the rotation of the connecting rod 7 can be facilitated. Through the setting of the servo motor 10, its output end can drive the second gear 11 to rotate. The number of the servo motor 10 and the second gear 11 are both two groups. Thus, when the servo motors 10 are started synchronously, they can drive the second gears 11 to rotate synchronously, and can more easily drive the first gear 9, so that the connecting seat 8 and the suspension 12 can change directions. By providing the first support arm 14 and the second support arm 15, which cooperate with the T-shaped pile 13 and the suspension 12 to form a stable triangular structure, the stability of the suspension 12 can be improved. Through the setting of the T-shaped pile 13, its top is slidably connected to the chute 23 inside the splicing plate 16, which is conducive to improving the load capacity of the suspension 12 without affecting the rotation of the suspension 12. Through the setting of the splicing plates 16, the number of which is four, they can be spliced with each other to surround the supporting square column of the building. And by rotating the second screw rod 18, the right-angle plate 20 can be driven to move horizontally, so that the right-angle plate 20 can abut against the four corners of the supporting square column, which is conducive to further improving the overall stability of the device. A hoisting mechanism 24 is slidably installed on the surface of the suspension 12. The hoisting mechanism 24 includes a traveling wheel 241, a traveling motor 242, a brake 243, a winding and unwinding motor 244, a steel wire rope 245 and a hook 246. The traveling motor 242 can drive the traveling wheel 241 to roll, which is conducive to making the hoisting mechanism 24 travel along the suspension 12. Through the setting of the brake 243, it is beneficial to lock the traveling wheel 241.

Anti-slip pads 25 are fixedly connected to the opposite sides of the first fixing plate 1 and the second fixing plate 3. Through the setting of the anti-slip pads 25, it is beneficial to increase the resistance between the first fixing plate 1 and the second fixing plate 3 and the supporting square column. The number of the servo motor 10 and the second gear 11 are both two groups, and the two groups of second gears 11 are both meshed with the first gear 9. Thus, when the two groups of servo motors 10 are started synchronously, it is beneficial to drive the two groups of second gears 11 to rotate synchronously, so as to facilitate driving the second gear 11 to rotate. A fixing rod is fixedly connected between the first support arm 14 and the second support arm 15. Through the setting of the fixing rod, the stability can be improved. The top of the T-shaped pile 13 is slidably installed in the chute 23, so that the T-shaped pile 13 can rotate in the chute 23. The top of the T-shaped pile 13 is restricted by the chute 23 and the splicing plate 16, which is conducive to improving the load capacity of the suspension 12. The right-angle plates 20 are arranged in an equidistant circular array. By rotating the second screw rod 18 to drive the right-angle plates 20 to abut against the four corners of the supporting square column, the stability can be increased.
[0023] Working principle of the utility model: During installation, first separate the four splicing plates 16, then splice them around the four corners of the supporting square column of the building. During the splicing process, insert the T-shaped pile 13 into the sliding groove 23, and then complete the splicing of the splicing plate 16 by passing the screw three 21 through the splicing plate 16 and tightening the nut two 22. Then rotate the screw two 18 to drive the right-angle plate 20 to move horizontally, so that the right-angle plate 20 can abut against the four corners of the supporting square column. Then place the fixing plate one 1 and the fixing plate two 3 on both sides of the supporting square column of the building respectively, and then complete the fixation of the fixing plate by passing the screw one 2 through the fixing plate one 1 and the fixing plate two 3 and tightening the nut one 4. After installation, by controlling the two groups of servo motors 10 to start synchronously, the gear two 11 can be driven to rotate synchronously, so that it can more easily drive the gear one 9, thereby changing the directions of the connecting seat 8 and the suspension 12. By providing the support arm one 14 and the support arm two 15, which cooperate with the T-shaped pile 13 and the suspension 12 to form a stable triangular structure, thereby improving the stability of the suspension 12. The T-shaped pile 13 can improve the load capacity of the suspension 12 and does not affect the rotation of the suspension 12. By the traveling motor 242, the traveling wheels 241 can be driven to roll, which is beneficial for the hoisting mechanism 24 to travel along the suspension 12. The setting of the brake 243 is beneficial for locking the traveling wheels 241. By the retracting and releasing motor 244, the retracting and releasing roller can be driven to roll, thereby retracting and releasing the steel wire rope 245 to adjust the height of the hook 246 and lift the goods. Among them, the electrical equipment in this device is externally connected to the power supply and is controlled to operate and shut down through the supporting control switch.
