Embodiment 1
[0032] Such as Figures 1 to 7 The double-pitch double-pin shaft heavy-duty conveyor chain is assembled by connecting and assembling several chain link units, and the chain link unit includes an inner chain plate 2 ( Figure 5 is the shape of inner chain plate 2), outer chain plate 1 ( Figure 4 is the shape of outer chain plate 1), pin group ( Figure 7 is the shape of the long pin shaft 4, Figure 8 It is the shape of short pin shaft 5) and guide plate 3 ( Figure 6 is the shape of the guide plate 3), the inner chain plate 2 and the guide plate 3 are arranged inside the outer chain plate 1, and the guide plate 3 cooperates with the guide groove on the sprocket to limit the lateral movement of the conveyor chain ; The pin group includes short pins 5 and long pins 4 that can roll relatively; hole; the short pin shaft 5 and the long pin shaft 4 pass through the first shaft hole, and the short pin shaft 5 is restricted from rotating in the circumferential direction of the fi...
Embodiment 2
[0045] The basic structure of this embodiment is the same as that of the embodiment, the difference is that the two ends of the long pin shaft 4 protrude from the outer surface of the second shaft hole, and the two ends are connected with the outer chain by pressure riveting. Plate 1 is fixedly connected, and this connection mode will form a riveting head on the outside of outer chain plate 1.
