OVERHEAD BELT CONVEYOR Russian patent published in 2005 - IPC

FIELD: mechanical engineering; overhead belt conveyor.

SUBSTANCE: proposed conveyor with overhead belt contains endless belt closed on drive and tension drums, brackets with running rolls secured on free ends of brackets, guides for running rolls secured on frame, tension drum trolley with guides for running rolls secured on trolley. Running rolls are provided with semiround rim in cross section, and guides for running rolls are made with cross profile concave to side of running rolls, and radius of curvature of inner surface of guides is taken greater than radius of rounding off of running roll rims. Support member is secured on side of bracket opposite relative to each running roll for interaction through additional guides of angular profile in cross section which are cantilever secured on guides of tension drum trolley for resting on guides of conveyor frame and sliding along said guides. Length of additional guides corresponds to maximum gap between guides of frame and trolley of tension drum formed at stretching of belt. Invention improves performance characteristics of overhead belt conveyor of considerable length owing to possibility of implementing and simplifying design of tension devices with increased travel of tension drum, reduced metal usage, reduced number of running rolls by half, reduced labor input at maintenance and repair of conveyor with overhead belt.

EFFECT: improved performance characteristics of overhead belt conveyors.
