OVERHEAD BELT CONVEYOR Russian patent published in 2006 - IPC B65G15/08 B65G21/10 B65G23/44 

FIELD: mechanical engineering; materials handling facilities.

SUBSTANCE: invention relates to overhead belt conveyors. Proposed conveyor contains endless belt closed in vertical plane and forming carrying and return runs with brackets attached to belt sides on which running rolls are installed for engagement with guides secured on posts, and tensioning device. Tensioning device consists of tension drum arranged on trolley over which belt passes. Trolley is hinge-connected with spatial truss one side walls of which angle-shaped sliding supports are secured for engagement with semiround guide running rolls made in from of disk rollers, and disk rollers proper. Semiround guides are pointed by convex part to side of longitudinal axis of conveyor and are provided with hinge joints at distance "l" from free ends from side of tension drum for turning in vertical plane, where "l" is maximum travel of tension drum trolley. Free end of truss is furnished with rolls. Length of truss is equal to maximum travel of tension drum trolley. Tension drum is made stepped.

EFFECT: simplified design of running gear, possibility of use at increased length of transportation of loads.
