DOUBLE-LOOP BELT-ROPE CONVEYOR Russian patent published in 2014 - IPC B65G17/02 B65G23/00 B65G23/32 

FIELD: transport.

SUBSTANCE: conveyor consists of belt (3) closed on driving (1) and tensioning (2) drums, as well as of closed on driving (4) and tensioning (5) pulleys of pulling loop consisting of two ropes (6, 7) which support belt load-carrying branch. The ropes are supported by rollers (10, 11) with flanges. Belt boards are supported by inclined rollers (12, 13). Along the length of conveyor under belt load-carrying branch dual driving units are located. These driving units are made in the form of double-grooved friction pulleys (14, 15) fixed on common shaft (16) which is connected with rotary drive (17). Ropes can round friction pulleys for full wrapping angle of 360 degrees. Driving units are located with possibility to support load-carrying branch of conveyor belt. Rounding friction pulleys by ropes on adjacent along the length of conveyor dual driving units is performed with lateral displacement of ropes when they are transferred to the second groove of each driving unit, in opposite directions. Rotary drive of each shaft with two driving units attached to it can be placed on one side or on two sides of dual driving unit.

EFFECT: higher pulling force of drive.
