TUBULAR BELT CONVEYOR Russian patent published in 2009 - IPC B65G15/08 

FIELD: mechanics.

SUBSTANCE: conveyor consists of supports for belt (1) in conveyor middle part in form of plates (3) oriented along the strip longitudinal axis and fixed on the inner side of rings (4) made from round-link chains. Rings are hinged to "П"-shaped supports (6) of conveyor frame, which are connected on the top by longitudinal beam (5) by means of vertically oriented suspensions (7). Length of suspensions is chosen from the condition of forming the profile of the top part of each semi-ring along the arc of the circle. Attachment points of suspensions to the ring are located in its upper part, in diametrically opposite position in the middle part, and within arcs of the circle between these points. Surface of plates from the belt is coated with antifriction material layer. Neighbouring plates are located with minimum clearances to each other and provided with edges bent outwards from the belt. Each plate of the group covering the belt tray across the whole of its perimetre is fixed on the two above rings. Distance between all the rings is accepted the same.

EFFECT: simplifying the design of supports, improving conveyor operating reliability, reducing labour input of maintenance thereof, and providing the possibility of transporting large loads.
