Abstract
A steering control system of an overhead working truck comprises an up-to-platform potentiometer, a steering sensor, a left rotation solenoid valve, a right rotation solenoid valve and a controller. The up-to-platform potentiometer and the steering sensor serving as input are connected with the controller. The controller is used for controlling the left rotation solenoid valve and the right rotation solenoid valve to be opened or closed. The up-to-platform potentiometer is a knob with steering angle indication. The steering sensor transmits steering angle information to the controller, and the controller compares the difference value of the up-to-platform potentiometer and the steering sensor and then controls the left rotation solenoid valve and the right rotation solenoid valve to be opened or closed, so that the actual steering angle degree measured by the steering sensor is the same as the value indicated by the up-to-platform potentiometer. The steering control system has the advantages that the actual steering angle of the overhead working truck can be accurately learned; an operator only needs to rotate the up-to-platform potentiometer to a certain scale as needed, so that operation is easier and more convenient, discomfort caused by height fear is avoided, and meanwhile safety is improved.
Description
Technical field
The present invention relates to a kind of steering control system of engineering truck, particularly a kind of aerial platform steering control system.
Background technology
Common turning to of aerial platform is achieved in that operator stands in the button of pressing bar handle top in fence at present, and while pressing the button on the left side, vehicle turns left, and while pressing the button on the right, vehicle is turned right.The power-off of the rear steering of loosing one's grip electromagnetic valve.When turning to, the initial steer angle of wheel flutter differs and is decided to be zero next time, and in order to observe the initial steer angle of wheel flutter, operator wants head to stretch out the actual angle that fence is looked down wheel., there is certain drawback in the above-mentioned mode turning to of taking turns, when job platform is elevated to 8 meters, when even walk in 10 meters of above high-altitudes, operator can feel significantly to rock, and head stretches out the situation that fence is observed front-wheel, can, because probably height feels at full stretch, even produce potential safety hazard.
Summary of the invention
Goal of the invention: the object of this invention is to provide a kind of aerial platform steering control system that just can know initial steer angle by control desk high scale in observation car.
Technical scheme: a kind of aerial platform steering control system, comprise and be arranged on the potentiometer of appearing on the stage, rotation direction sensor, left-hand rotation electromagnetic valve, right-hand rotation electromagnetic valve and the controller on control device in service platform, the described potentiometer of appearing on the stage is connected with controller as input with rotation direction sensor, and described controller is controlled the break-make of left-hand rotation electromagnetic valve and right-hand rotation electromagnetic valve; The described potentiometer of appearing on the stage is the knob with steering angle indication, described rotation direction sensor passes to controller by deflection angle information, relatively the appear on the stage difference of potentiometer and rotation direction sensor of controller, controller is handled left-hand rotation electromagnetic valve or right-hand rotation electromagnetic valve break-make, and then the actual steering angle that rotation direction sensor is recorded is identical with the numerical value of the potentiometer indication of appearing on the stage.
The potentiometer of appearing on the stage is arranged on the control device in service platform, rotates the potentiometric knob of appearing on the stage, and the potentiometric output signal end of appearing on the stage just changes.During left steering, to the anticlockwise potentiometer knob of appearing on the stage; Relatively the appear on the stage value of potentiometric value and rotation direction sensor of controller, output signal makes electromagnetic valve energising, and when turning to while arriving setting value, controller stops the energising of left-handed turning electromagnetic valve.Same reason, to the right rotation potentiometric knob of appearing on the stage, the energising of right-hand rotation electromagnetic valve, turns to and stops while turning right to setting value.By said method just can accomplish the to appear on the stage angle value of potentiometer indication, equal the steering angle of wheel flutter below.The fence that operator stretches out High Altitude Platform without head just can be known the actual angle of wheel flutter below, thereby can avoid because observing the discomfort that wheel causes below, has also improved safety simultaneously.
Preference, described rotation direction sensor is displacement pickup, is arranged on steering cylinder and measures the length that piston rod stretches out, and by controller, is converted into deflection angle.
Preference, described rotation direction sensor is angular transducer, is arranged on steering shaft, the output signal of angular transducer can calculate deflection angle by controller.
Beneficial effect: the present invention can accurately learn the actual steering angle of aerial platform; Operator only need to be as required by the potentiometer rotation of appearing on the stage to certain scale place, operate easylier, avoided because the high discomfort sensation causing probably, the while has also been improved safety.
