Abstract
For use in underground mining, in particular coal mining, a chain belt is provided, which consists of the standard vertical links and horizontal links which preferably have double helical surfaces. These horizontal links with the double helical surfaces are connected to a symmetrically constructed pusher, whereby either the base and the guide shoes, or only the base are shaped symmetrically. The symmetry plane is exactly in the center, when viewed in conveying direction, so that such a pusher can be reversed either in relation to the base or in its entirety, or together with the entire chain belt. This results in much higher lifespans.
Claims12
Chain belt for chain conveyors used in underground mining and tunnel construction, having vertical and horizontal links and pushers spaced apart and encompassing the horizontal links, said pushers being equipped at the end with guide shoes adapted to the guide profile of the troughs, characterized in
- that the guide shoes (5) are connected releasably to the base (8) of the pusher (4);
- that the guide shoes (5) are symmetrical when viewed transversely to the conveying direction (9);
- and that the base (9) is divided lengthwise in the center and has identically constructed top (10) and bottom (11) parts.
