RIG FOR SURVEY OF BELT DEFORMATION OF CABLE-BELT CONVEYOR WITH SUSPENDED SUPPORTS Russian patent published in 2008 - IPC B65G17/02 G01M19/00 

FIELD: transportation.

SUBSTANCE: rig contains frame, stretch of conveyor belt with capability of location on it sample of conveyed cargo, supporting equipment for belt, recording instrument. Stretch of belt is located on hook-like suspension with fixing on it belt from side of its one edge, adjoining to suspensions vertical elements, which are fixed on laminar-roller chain, closed in horizontal plane and rounding driving and snatch block and also runner. Each suspension is outfitted by roller, mounted on axes and rotatable in vertical plane and interaction with bearing gutter fixed on runner, by its perimeter. Fixed on frame runner is implemented as tandem to each other straight portion and curve portions with stepped reduction of fixed radius of curvature from portion to portion as far as its moving off from straight portion with bump from side of stretch of conveyor belt. Start and end of each curve portion are marked. Length of each curve portion is accepted not less then length of stretch of conveyor belt.

EFFECT: invention allows providing of surveying parameters of strained state of grooved conveyor belt of cable-belt conveyor with suspended supports and reasonable choose diameters of driving and tightening rope sheaves and permissible minimum radius of conveyor route bending in plane.
