FIELD: mechanical engineering; conveyors. ^ SUBSTANCE: invention relates to conveyors with overhead belt for transportation of lump and loose materials. Proposed overhead belt conveyor has frame, endless belt closed on drive and tension drums to form carrying run and return run, two carrying flexible members, each made in form of belt T-shaped in cross section and arranged for resting of its flange both on carrying and return runs on two disk rollers with rounded off rims installed square to each other and located on conveyor frame symmetrically relative to belt. Edge surfaces of conveyor belt are connected with said belts by clamps fastened on conveyor belt edge surfaces and belts and inter connected by pins to turn clamps relative to each other. Flanges of belts are provided with wedge-like slot cutouts at 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 edge of flange. Slot cutouts are equally spaced over belt length and are displaced relative to each other on opposite sides of flange through half of pitch. Pitch of slot cutouts and pitch of spacing of disk rollers over length of conveyor are found from inequality nl<lr<(n+l)l where lr is disk roller spacing pitch; n is whole number; 1 is slot cutout pitch. ^ EFFECT: reduced cross rigidity of belts, increased their service, life, reduced diameters of drive, tension and guide drums. ^ 4 dwg |
