CURVILINEAR MULTIDRIVE OVERHEAD BELT CONVEYOR Russian patent published in 2003 - IPC

FIELD: mechanical engineering; conveyor transport. SUBSTANCE: proposed conveyor has support frame with closed tubular guide secured at both sides of conveyor on frame, and endless conveyor belt connected with hangers, either directly or through intermediate members, to provide movement of hangers along tubular guides. Hangers are connected from outer side of curvilinear section of conveyor by endless pull chain to transmit traction forces to belt through hangers or intermediate members. Chain is passed over deflecting sprockets on curvilinear section or over rollers taking up radial forces. Conveyor is furnished with end drives or is provided with intermediate drives from outer side of curvilinear section to transmit drive force to endless pull chain. Conveyor is simple in design and reliable in operation providing transportation of load along trajectory curvilinear in horizontal plane without exposing the belt to additional tensional tension with provision of reduction of loads on hangers and belt, including return run of belt. EFFECT: simple design, improved reliability in operation. 2 cl, 5 dwg
