[0010] Technical effects and advantages of the utility model:

[0011] 1. The driving motor can drive the driving sprocket to rotate, and the inert sprocket can drive two ring chains to operate. The ring chains can drive multiple forks to achieve cyclic lifting, so that the goods at low places can be lifted to high places. The cyclic lifting method can continuously transport the goods in a cyclic manner, thereby improving the transportation efficiency of the goods;

[0012] 2. Connecting multiple forks with the ring chain through joint bearings can make the forks rise and fall cyclically following the rotation of the ring chain. At the same time, it can ensure that the transported forks can move in a horizontal direction, thereby improving the stability of cargo transportation and lifting. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] As attached Figure 1-5 A heavy-duty circulating hoist shown includes a frame 1, wherein a driving motor 2, a chain tensioning mechanism 3, an inert sprocket 4, a connecting roller machine 1 5 and a connecting roller machine 2 6 are arranged inside the frame 1;

[0021] The driving motor 2 is installed at the bottom of the frame 1, the chain tensioning mechanism 3 is at the top of the driving motor 2, a driving sprocket 7 is arranged between the chain tensioning mechanism 3 and the driving motor 2, a toothed disc 11 is coaxially driven at the output end of the driving motor 2, and a driving chain 12 is arranged between the toothed disc 11 and the driving sprocket 7, and the toothed disc 11 and the driving sprocket 7 are meshed with the driving chain 12.

[0022] It can be understood that in the above structure, the driving motor 2 can drive the toothed disc 11 at its output end to operate, and drive the driving sprocket 7 to operate through the meshing driving sprocket 7, so as to provide kinetic energy to the circulating elevator.

[0023] Two ring chains 8 are also provided inside the frame 1, and the two ring chains 8 are respectively installed in parallel on the corresponding inert sprockets 4, the two ring chains 8 are respectively meshed with the corresponding inert sprockets 4, and the inert sprockets 4 are connected to the chain tensioning mechanism 3, and a plurality of forks 9 are provided between the two ring chains 8, the forks 9 are welded by a plurality of stainless steel square tubes, and a joint bearing 10 is provided at the connection between the forks 9 and the ring chains 8, the joint bearing 10 is welded on the ring chains 8, and the forks 9 are connected to the ring chains 8 through the joint bearing 10.

[0024] It can be understood that in this structure, when the driving sprocket 7 is in operation, it can drive the two ring chains 8 to circulate through the inert sprocket 4, so that the ring chain 8 drives multiple forks 9 to realize up and down lifting circulation through the joint bearing 10, and the up and down lifting circulation forks 9 can drive the goods to lift. In this structure, the chain tensioning mechanism 3 can have the effect of tensioning and adjusting the ring chain 8 to ensure the stable operation of the ring chain 8. The specific principle of the chain tensioning mechanism 3 is the existing technical solution and will not be elaborated here.

The functions of the connecting roller machine 1 5 and the connecting roller machine 2 6 can both realize the transportation of goods to the inside of the elevator, or the transportation out of the inside of the elevator. For example, the connecting roller machine 2 6 transports the goods from the bottom to the inside of the circulating elevator, and after circulating lifting by the circulating elevator, it is transported out from the connecting roller machine 1 5 at the top.

[0026] Working principle of this utility model:

The ring chain 8 drives multiple forks 9 to realize cyclic lifting, so that the goods at a low place can be lifted to a high place. When the goods are lifted to a high place, the lifted goods can be transported out through the connecting roller machine 1 5.
