OVERHEAD BELT CONVEYOR Russian patent published in 2005 - IPC

FIELD: mechanical engineering; conveyors.

SUBSTANCE: invention relates to conveyors with overhead belt for transportation of lump and loose materials. Proposed conveyor with overhead belt contains frame, endless belt closed on drive, tension and guide drums to form carrying and return runs, two carrying flexible members of T-shaped cross section relative to belt plane arranged for thrusting by flanges both on carrying and return runs of belt against two disk rollers with rounded off rims installed square to each other on conveyor frame symmetrically relative to carrying members. Each flange of carrying member is provided with wedge-like slot cutouts from two sides orientated square to longitudinal axis of belt and made over entire width of projecting parts of flange with widening of slot cutout towards outer edges of flange. Slot cutouts are equally spaced over length of belt and are displaced at opposite sides of flange relative to each other through half of pitch, and pitch of slot cutouts and pitch of spacing of disk rollers over length of conveyor are found from inequality nl<l_r<(n+l)l where l_r is disk roller spacing pitch; b is whole number; 1 is slot cutout pitch.

EFFECT: simplified design, reduced cross rigidity of carrying members and increased their service life, reduced diameters of drive, tension and guide drums.
