Abstract:
1. A belt conveyor device comprising: a continuous conveyor belt movable in a conveying plane within a conveying duct on a drive pulley and a tail pulley inside the conveyor belt, and within a frame structure defining the conveying duct and enclosing the conveyor belt at least at both conveyor belt side edges, the frame structure having one of a mechanically or hydraulically actuated drive for adjusting engagement at least one of the pulleys and for moving the pulleys into a replacement position out of the conveyor belt, the frame structure having (i) at least one alternative space outside the conveying duct that defines the replacement position of the respective drive and tail pulleys and (ii) permanently or temporarily mounted guide means for supporting each of the drive and tail pulleys at least while the pulley is moved by the adjustment drive into the replacement position, and wherein each pulley is mounted (a) with one pulley end detachably in the frame structure and free to swivel parallel to the conveying plane out of the conveyor belt in the frame structure at the other pulley end to the replacement position about an adjusting axle in the frame structure that is transverse to the pulley axle and perpendicular to the conveying plane, or (b) completely detachable from the frame structure to be laterally shifted out of the frame structure when detached into the replacement position in the direction of a pulley axle and parallel to the conveying plane.
