METHOD OF AND DEVICE FOR CATCHING TORN-OFF FLEXIBLE TRACTION MEMBER OF LIFTING-AND-TRANSPORTING MACHINES Russian patent published in 2007 - IPC B65G43/06 

FIELD: mechanical engineering; belt conveyors.

SUBSTANCE: according to proposed method of catching of flexible traction member-belt of lifting-and-transporting machine in case of belt falling, rollers change direction of their rotation cutting in ratchet mechanism which stop rotation of roller. Roller are moved with torn-off belt acting onto levers which control drum and shoe with wavy surfaces clamping the belt by said surfaces of drum and shoe and holding the belt. Belt catching device has drum with wavy surface installed eccentrically on axle with supports, shoe with wavy surface installed opposite to drum, and rollers with ratchet mechanisms and levers engaging with belt. Rollers are made for changing direction of rotation at breaking of belt and then, as a result of operation of ratchet mechanism, stop and, moving together with torn off belt and shifting the levers which control drum and shoe, catch belt by drum and shoe and hold it between wavy surfaces.

EFFECT: improved reliability of belt catching.
