BENCH FOR INVESTIGATION OF PARAMETERS OF CONVEYOR WITH SUSPENSION BELT AND SIDE ROLLER SUPPORTING DEVICES Russian patent published in 2013 - IPC G01M17/00 B65G15/00 

FIELD: machine building.

SUBSTANCE: bench includes frame (1) and belt (4) closed on drive (2) and tension (3) drums. Straps (5) with projections (6) are attached to inside surface of the belt edges. Rollers (7, 8) on upper branch of the belt are installed with possibility of being rotated on axes (11, 12), and on the non-working branch of the belt, rollers (9, 10) are installed so that they can be rotated on axes (13, 14). One roller of upper branch of the belt is installed so that it can interact with the projection edge, and the other roller has the possibility of being interacted with outside surface of the belt edge. Rollers are offset relative to each other through the length of the belt, and the strap joint is offset throughout the belt length relative to its joint. Above upper branch of the belt, slide (19) is arranged so that it can be offset in vertical plane relative to guides (20, 21) of the frame. On lower part of the slide on axes (22) there installed are disc rollers (23) with possibility of being rotated. Slide is equipped with drive (24) of its offset in vertical plane and instrument (25) for recording the hold-down force of disc rollers to upper branch of the belt. Tension drum is equipped with mechanism (26) of its offset and instrument (27) for recording the value of tension force. Drive unit (28) of the drive drum provides the possibility of changing the belt movement speed. Distance between drive and tension drums is accepted equal to not less than the length of three bays of roller carriages of the load-carrying branch of the conveyor belt.

EFFECT: carrying out investigations for evaluation of operating parameters of the conveyor.
