Description
Technical field
The present invention relates to a kind of tester for testing of aerial work platform, put down particularly to a kind of scissor-type work high above the ground
The lifting commerical test control system of platform, belongs to technical field of engineering machinery.
Background technology
By battery as power source, drive motor, motor drives hydraulic pump, warp to scissor aerial work platform again
Cross the shunting of hydraulic valve, hydraulic oil drives final hydraulic unit execution walking motion, go to action, lifting action.Down maneuver
When, motor and hydraulic transmission part do not work, and under load and workbench Gravitative Loads, elevating ram shrinks workbench and falls.
Aerial work platform is used for work high above the ground, and operator can be engaged in pipe laying, material handling, maintenance on platform
The contents such as operation.After operator climbs up platform, so that platform is risen or fallen by manipulating joystick, also may be used by joystick
So that vehicle to run, to reach the purpose of work high above the ground.When ground controls, operator stands in control panel side, and pressing is pressed
Button can make platform rise or fall.For safety, after release control handle or button, platform action stops.
Aerial work platform dynamical system is by battery, motor, hydraulic pump, hydraulic valve bank, hydraulic jack, movable motor
Or the composition such as hydraulic motor.Control section is by upper mounting plate controller assemblies, lower platform controller, electric machine controller, lower platform control
Assembly composition processed.
After the controller of aerial work platform receives input signal, output control signal is to electric machine controller, motor control
Device processed makes motor rotate by given speed, and motor drives hydraulic pump operating, and controlled magnetic valve is connected, and hydraulic jack is stretched
Contracting makes platform rise or fall.The controlled motor of speed can also make the steering in vehicle to run and walking process.From
And operator can be so that lifting platform can make vehicle to run on platform.
When scissor aerial work platform does lifting commerical test, Normal practice is：Operator is in the control panel of platform
Side, bends over or partly squats down on the ground, and pins and rises or fall switch, because being crawl operation, action of loosing one's grip stops, so lifting
When, operator needs holding to pin switch.
The shortcoming of this kind of way is：Lasting operation makes operator's fatigue, because of operator apart from vehicle closely, lifting process
Middle motor and the hydraulic oil sound that sends of motion, also can make operator not feel well.
