Monitoring angular relationships of ramps

机译:监视斜坡的角度关系

摘要

Apparatus is provided for monitoring angular relationship between a ramp (1) pivotally supported at one end (5) on a ship, and an adjoining surface (2) such as an adjustable bridge ramp pivotally supported at one end (3) on a jetty, quay or landing stage. A first sensor provides an output representing the magnitude and sign of the angle ( theta A) of the ramp (1) relative to a fixed plane (7). A second sensor provides an output representing the magnitude and sign of the angle ( theta B) of the adjoining surface (2) relative to a fixed plane (8). An amplifier, receiving the outputs from the sensors, monitors the angular difference between the ramp (1) and surface (2). A pair of comparators receive output signals from the amplifier and are each set to trigger at a particular signal level but of opposite polarity, providing control signals to mechanical means for adjusting the ramp angles to maintain them within safe limits.
