HIGH-ANGLE BELT CONVEYOR Russian patent published in 2003 - IPC

FIELD: materials handling facilities. SUBSTANCE: invention relates to belt conveyors provided with pressure circuit. Proposed conveyor has brackets with twin running rolls secured on belt edges for resting on tubular guides on carrying and return runs of belt, frame, endless pressure circuit closed on end blocks and arranged over carrying run of belt and consisting of round-link chains interconnected by lengths of cross chains for engagement of lower run of pressure circuit with transported load, and for engagement of upper run with support rolls. Pressure circuit is double chain, provided with additional cross ties in form of rigid bars secured to chains for engagement of free ends of bars with brackets of running rolls. Distance between adjacent bars is taken on condition that nl_r<l<(n+1)l_r; l<L where 1 is distance between bars, l_r is pitch of running rolls over length of belt, n is even number, L is distance between end blocks of pressure circuit. Invention makes it possible to provide driving of pressure circuit directly from belt. EFFECT: simplified design, improved reliability in operation. 2 dwg
