fig. 3 is a schematic diagram of the assembly of a solid link and a hollow link in the present utility model.

In the figure: 1. a chain rope; 1a, chain links; 1a-1, empty links; 1a-2, solid links; 2. a chain piece; 2a, grooves; 3. a wear ring; 4. wear-resistant plate.

Detailed Description

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

As shown in fig. 1 to 3, a chain for a pipe chain conveyor comprises a chain rope 1 formed by connecting a plurality of chain links 1a in series one by one, wherein each chain link 1a comprises an empty chain link 1a-1 and a real chain link 1a-2, a chain piece 2 is arranged on the middle of each real chain link 1a-2, at least one empty chain link 1a-1 is arranged between every two adjacent real chain links 1a-2, a detachable wear-resistant ring 3 is arranged on the arc surface of each chain piece 2, the outer arc outline of the wear-resistant ring 3 is larger than that of each chain piece 2, and the chain is integrally formed by organic materials with strong wear resistance, and because the wear-resistant ring 3 is directly in frictional contact with the inner wall of the conveying pipe, the service life of the conveying chain can be effectively prolonged by adopting materials with strong wear resistance.

As shown in fig. 2, the solid chain link 1a-2 comprises two U-shaped rings with opposite openings, the tail ends of the U-shaped rings are respectively connected with one chain piece 2, one chain piece 2 is provided with external threads and the other chain piece 2 is provided with matched internal threads, the two chain pieces 2 are butted into a whole through reverse screwing, after the two chain pieces are butted, a groove 2a for accommodating the wear-resistant rings 3 is formed in the outer edge of the chain piece 2, more than or equal to 1 wear-resistant ring 3 is arranged between every two oppositely combined chain pieces 2, and when a new wear-resistant ring 3 needs to be replaced, the connected chain pieces 2 are separated through reverse screwing.

The hollow chain link 1a-1 is in a runway shape and comprises a semicircular ring and a straight column which are connected, the intrados of the semicircular ring and the intrados of the U-shaped ring are respectively attached with a wear-resisting piece 4 with the degree of 0.5 mm-5 mm, refer to fig. 3, when the hollow chain link 1a-1 and the solid chain link 1a-2 are buckled, the wear-resisting piece 4 isolates the semicircular ring from the U-shaped ring so as to prevent the semicircular ring from directly contacting with the U-shaped ring, therefore, the service lives of the semicircular ring and the U-shaped ring are long, after the pipe chain conveyor is put into operation, the wear of the wear-resisting piece 4 reaches a design value, the wear-resisting piece 4 is directly replaced without replacing the whole chain link 1a, so that the consumption of resources is effectively reduced, the use and maintenance cost of conveying equipment is reduced, and chain breakage caused by exceeding the abrasion of the chain link 1a is avoided.

While the utility model has been described with respect to the preferred embodiments, it will be understood by those skilled in the art that variations, modifications and additions may be made without departing from the spirit of the utility model.
