AERIAL LADDER BOOM AUTOMATIC CONTROL APPARATUS OF FIRE TRUCK WITH AERIAL LADDER

摘要

The present invention provides an automatic control system of the ladder fire truck ladder boom. The control system of the present invention and the multi-stage boom of the ladder to be installed around the standing axis of rotation to enable the center to the vehicle body, a boom of the ladder upright boom to the upper cylinder and a boom ladder on a ladder fire engine comprising a cable drive device to deploy the In the horizontal distance measuring means for measuring the horizontal distance of the point and the rotation center axis of the fire ladder and the boom; Vertical angle measuring means for measuring a vertical angle of the fire point of the boom and the rotating center axis of the ladder; And a horizontal distance measured from the horizontal distance measuring means, to process the V-angle from the vertical angle measured by each measuring means calculates the deployment length of the ladder on the boom angle and the standing point of the fire ladder on a fire point of the boom control for outputting a signal e and units; The electronic control unit of the boom standing ladder and the ladder angle control signal in response to a control signal length boom deployment boom cylinder and a cable drive system to control the expression Sikkim rising the fire point of the ladder as well as a boom and a hydraulic device for deployment into the fire point.
