Zusammenfassung:	A three-ring chain device for a mine car comprises a first outer chain ring (1), a middle chain ring (2) and a second outer chain ring (3), the first outer chain ring (1) is provided with a first lap joint part (11) and a second lap joint part (15), and the lap joint parts distributed along the center line of the first outer chain ring (1), the center line of the middle chain ring (2) and the center line of the second outer chain ring (3) are arranged between the first lap joint part (11) and the second lap joint part (15). Through the first lap joint part (11) and the second lap joint part (15), forging and hot fusion connection in the first outer chain ring (1), the middle chain ring (2) and the second outer chain ring (3) is achieved, and the first outer chain ring (1), the middle chain ring (2) and the second outer chain ring (3) are embedded, tiled and subjected to hot fusion to form a middle connecting layer body. The technical problem that the ends of the round steel bars are connected together in a we
