[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0029] like Figure 1 As shown, the utility model proposes a self-balancing lifting and suspension device, including a lifting device 1 and a guide assembly 2, wherein a self-balancing device 3 is suspended at the lower part of the lifting device 1, and the lifting device 1 is used to pull the self-balancing device 3 to rise and fall; wherein the lifting device 1 can be a chain hoist, but is not limited to this structure, and the self-balancing device 3 can be driven to rise and fall by hooking the lifting device 1 to the self-balancing device 3, and after hanging objects on the self-balancing device 3, the suspension lifting can be realized.

[0030] In order to better ensure the stability of the lifting of the suspended objects, a guide assembly 2 can be installed at the bottom of the lifting device 1. In this embodiment, Figure 2 , Figure 3 As shown, the guide assembly 2 can be a guide rail, and the suspension frame 4 of the self-balancing device 3 is provided with a roller 12, and the roller 12 is clamped on the side wall of the guide assembly 2.

The number of rollers is not limited to the above number, that is, it can move up and down along the guide rail, and the structure of the guide rail can be that the roller is pressed on the outside of the guide rail, or the roller is directly pressed on the guide assembly, and the matching form of the roller and the guide rail is not limited.

[0031] Another embodiment of the guide assembly 2 is: Figure 8 As shown, the guide assembly is two parallel guide bars fixed on the wall, and the rollers 12 on both sides of the roller are pressed on the guide bars respectively to achieve up and down movement.

[0032] What needs to be explained in this embodiment is: Figure 5As shown, the self-balancing device 3 includes a suspension frame 4, a turntable 5 rotatably connected to the suspension frame 4, a suspension assembly 6 is arranged on the turntable 5, the structure of the suspension frame 4 includes a horizontal support frame 7, the horizontal support frame 7 is a frame-shaped structure, a rotating shaft 8 is provided at the center of the frame-shaped structure, the center of the turntable 5 is connected to the rotating shaft 8, a bearing is provided between the turntable 5 and the rotating shaft 8, and the turntable 5 can rotate along the rotating shaft 8, wherein the shape of the turntable 5 is not limited, and can be circular or polygonal.

A limit switch is also provided in the shell. When the hanging part 9 rises to the limit switch, the limit switch can be triggered to control the start and stop of the lifting device. The form of the limit switch is not limited. It can be a mechanical travel switch or other inductive proximity switch.
