Title:
DETENT DEVICE FOR CONTINUOUS CONVEYOR
Document Type and Number:
Japanese Patent JPS59114208
Kind Code:
A
Abstract:
To permit unloading and release of statically stored dynamic energy in a run of a loaded conveyor, e.g. a mining conveyor belt, the return stop mechanism or back-run safety mechanism is coupled to a fixed structure, such as a frame (50, 73, 89) through a releasable friction coupling which is formed by a two-part holding ring (48, 49; 71, 72; 87, 88) coupled to the frame, and having facing inwardly directed surfaces which can be clamped, by controlled friction force against facing surfaces of an outer operating ring (45, 64, 84) of a ratchet or other one-way clutch or drive to prevent back-run or a return stop for the conveyor. Upon controlled release of the frictional engagement, for example by counter-acting spring force or releasing a spring force, the friction surfaces are permitted to slip, thus permitting dissipation of stored energy in the conveyor, for example due to sudden stoppage upon malfunction or external interference, for example by rocks, boulders or the like. The two-part holding ring is preferably constructed with interengaging telescoping ring parts to provide a protective surrounding structure, requiring only minimum radial space.
