Abstract
The utility model discloses a platform levelling and controlling system for a self-acting overhead working truck. The platform levelling and controlling system for the self-acting overhead working truck is characterized in that the signal output end of a platform gradienter is connected with a platform controller, and a levelling electromagnetic valve is controlled by the platform controller so as to drive a levelling actuating mechanism. On the premise of ensuring the safety, the platform not only can cause a button to be connected with the platform controller, but also can control the levelling electromagnetic valve to drive the levelling actuating mechanism through a hand-operated levelling switch so that the platform can be inclined to meet operational requirements. A turntable not only can cause the other button to be connected with a turntable controller, but also can control the levelling electromagnetic valve to drive the levelling actuating mechanism through the levelling switch. The turntable levelling and the platform levelling are interlocked. The platform levelling and controlling system for the self-acting overhead working truck not only has the automatic levelling function and ensures the safety and reliability of overhead working, but also can meet the requirements on various inclinations due to the hand-operated levelling function.
Description
Technical field
The utility model belongs to aloft work facility control technology field, relates to a kind of platform leveling control system of self-propelled aerial working car.
Technical background
The measure that existing high-altitude operation platform leveling equipment is mainly taked has the mechanical type auto-leveling mechanism, the automatic leveling of hydraulic electric control mode, and underaction can not satisfy certain bevelled needs in particular cases, and anti-misoperation is poor.
The utility model content
Technical problem to be solved in the utility model is the platform leveling control system that proposes a kind of self-propelled aerial working car, the platform leveling control system of this self-propelled aerial working car not only has automatic levelling function, also having the manual leveling worker can, both guaranteed that aloft work was safe and reliable, satisfy aloft work extraordinary circumstances bevelled needs again, anti-misoperation is good.
Technical solution of the present utility model is as follows:
A kind of platform leveling control system of self-propelled aerial working car, the manual leveling switch is connected with the electromagnetic valve that is used to drive the leveling actuating unit.
Manually enable button is connected with platform controller.
The signal output part of platform level indicator is connected with platform controller, and platform controller is by leveling solenoid-driven leveling actuating unit.
Platform controller and turntable controller communicate to connect.
The utility model adopts distributed PLC and bus control technology, and the PLC controller is gathered the obliquity sensor signal, thereby reaches automatic leveling by output pwm signal control electric-hydraulic proportion electromagnetic valve after the computing; Manual leveling switch and controller output-parallel are received the leveling electromagnetic valve, reach manual leveling and satisfy aloft work extraordinary circumstances bevelled needs.Before the manual leveling switch, add the leveling enable button, avoid maloperation.
Leveling turntable and platform leveling are interlocking.Interlock function realizes jointly that by hardware and software when mode selector switch was switched to the turntable pattern, the turntable manual leveling was effective, and the platform manual leveling is invalid, and when mode selector switch was switched to platform model, leveling turntable was invalid, and the platform manual leveling is effective.
Beneficial effect:
The utlity model has following technique effect:
The platform leveling control system of self-propelled aerial working car of the present utility model adopts automatic leveling and manual leveling to combine, and alerting ability is good, and applicability is strong, guarantees that aloft work is safe and reliable.In addition, platform controller and turntable controller in the platform leveling control system of self-propelled aerial working car of the present utility model communicate to connect, be specially and adopt the total wire joint of CAN, thereby ensureing that turntable control and platform controller can be worked in coordination with carries out leveling to platform and control.
Description of drawings
Fig. 1 is the overall structure block diagram of embodiment 1.
The specific embodiment
Below with reference to the drawings and specific embodiments the utility model is described in further details:
Embodiment 1:
As Fig. 1, the technical solution adopted in the utility model is: adopt the PLC control technology, its control system consists of: platform controller (PLC), manual leveling enable button, manual leveling switch, platform level indicator, leveling proportion magnetic valve, platform leveling actuating unit, platform inclination indicator lamp.System's principle of compositionality block diagram as shown in Figure 1.
Automatically leveling working process: the platform level indicator is exported to platform controller with detected platform dip angle signal, and platform controller is by handling, and output pwm signal is given the leveling proportion magnetic valve, the liter of control leveling system with fall, thereby reach the flat-bed leveling.
Guaranteeing under the safe situation, during angle that platform need tilt certain, needing to use the manual leveling function this moment.
The process of manual leveling: pin the manual leveling enable button with a hand, manually enable button is connected, and gives the controller enable signal simultaneously.Controller receives the manual leveling enable signal, shields automatic levelling function, and leveling is invalid automatically.Platform is leaned forward, with the another hand with the leveling switch connection to the shelves that lean forward, this moment, the proportion magnetic valve that leans forward was opened, leveling system is carried out forward swing, in the time of making the platform hypsokinesis, the leveling switch connection is arrived the hypsokinesis shelves, hypsokinesis this moment proportion magnetic valve is opened, and leveling system is carried out the hypsokinesis action.
This leveling system can also receive get off manual leveling signal and the control signal of following vehicle controller (being turntable controller) by the bus transmission, and according to this control signal the platform of aerial platform is implemented control, but the control signal of getting on or off the bus is an interlocking signal.
Claims (4)
1. the platform leveling control system of a self-propelled aerial working car is characterized in that, the manual leveling switch is connected with the electromagnetic valve that is used to drive the leveling actuating unit.
