Barter is the present and the future of international trade, especially for people who is starting in the import export business. Barter and more: Triangular operations.
Dumbbell pin is an important part connecting the middle slot and the middle slot of the fully mining scraper machine. Dumbbell pin is forged and made of alloy steel integral forging die. After heating and tempering, the strength and toughness of dumbbell pin can reach a complete state. Ensure safety and improve performance.
1. Purpose: The dumbbell pin is mainly used for the fixed connection between the scraper conveyer and the middle trough of the scraper transfer machine.
There are two types of dumbbell pins: one is the dumbbell pin connection (I-type dumbbell, single head, double head), and the other is the large ring connection (day ring).
In the process of fully mechanized working face advancing, scraper conveyor in central slot by its own gravity, coaling force and resistance and so on the many kinds of load combination, and by the ups and downs of scraper conveyor straightness, ground level, arbitrary bending Angle between the adjacent central slot and the influence of dumbbell pin their own strength, easy to cause the middle trough and dumbbell the wear and fracture of the pin, serious to the central trough links or release. Dumbbell pin design principle in the middle of the groove is in order to appear above the first broken dumbbell pin to reduce the middle hole bad so as to reduce the cost.
