Device for monitoring cable tension during producing steel cable conveyor belt, has pitch measuring device with sound receiver, which detects change of oscillation frequency and change of oscillation voltage by adjusting pitch

摘要

The device (1) has an elastomeric material cover plate, and clamping device (3) clamping cables (2) e.g. steel cables. A measuring device (4) i.e. pitch measuring device, controls the cable tension of each cable. A cable tensioning device (5) is provided in a specific position after evaluating the measurement result of the measurement device when each cable individually receives re-tightening. The pitch measuring device is provided with a sound receiver, which detects change of oscillation frequency and change of oscillation voltage by adjusting the pitch.
