Abstract
The present invention proposes the QR2S controller that can substitute the common QR2S type standard control flow route of current crane hoisting mechanism, especially suitable for the middle or small tonnage bridge of general control (control of rotor string resistance device), lifting mechanism of gantry crane.The indoor cam controller combination complexity of operation is efficiently solved, route is asymmetric and circuit is more, cannot directly use remote control control；The drawbacks of route protection link is relatively more, and control line road, which is easy to appear, is failure to actuate or malfunctions, and results even in weight downslide, accident occurs.It can be operated using conventional master controller or remote controler, output directly controls major loop contactor, reduces the quantity of electrical component, and simplified control route reduces manufacturing cost, eliminates safe hidden trouble, and improves the reliability of production efficiency and equipment.
Description
Technical field
The present invention relates to a kind of controllers for crane hoisting mechanism, especially suitable for general control (rotor string electricity
Hinder device control) middle or small tonnage crane hoisting mechanism.
Background technique
The middle or small tonnage bridge of general control at present, lifting mechanism of gantry crane use mostly 1992 it is improved
QR2S type standard control flow route.It operates indoor cam controller and gives operation signal to QR2S control flow, pass through control flow
Interior line combination, control when realizing different stalls to motor different characteristics, to realize lifting mechanism in different operating conditions
Under up and down movement.The control flow is suitable for the occasion for adjusting the speed with starting, brake request is not high.The disadvantage is that: operating room
Interior cam controller combines complicated, it is necessary to be dedicated cam controller, and can only use in operating room.Route asymmetry is simultaneously
And circuit is more, cannot directly use remote control control.Route link of protection is relatively more simultaneously, is not easy to be remotely controlled device control system
Transformation, be used for a long time, repair, safeguard it is improper, control route will occur being failure to actuate or malfunctioning, result even under weight
It is sliding, accident occurs.
Summary of the invention
The task of the present invention is proposition, one can substitute QR2S control flow, and conventional master controller or remote controler is used to grasp
Make, and realizes the controller of original function.The task of the present invention is what is completed in this way, it includes input isolation circuit, master control electricity
Road, output amplifier, it is characterised in that input isolation circuit acquires the operation signal of master controller or remote controler, is discriminated
And after judgement be not sent into governor circuit, preset control program in governor circuit, carried out according to the operation signal of different stalls in
Portion's logical combination, and give combined result to output amplifier, amplifying circuit directly controls the contactor of major loop, realizes
The control function of QR2S control flow.The present invention has the effect that can be grasped using conventional master controller or remote controler
To make, output directly controls major loop contactor, reduce the quantity of electrical component, simplified control route, the volume for reducing power control cabinet,
Reduce the workload of the requirement and assembly to assembly crewman, convenient for assembling, transformation, examination and maintenance, reduce manufacture at
This, eliminates safe hidden trouble, and improves the reliability of production efficiency and equipment.
Detailed description of the invention
Fig. 1 is the electrical diagram of the prior art.
Fig. 2 is using electrical diagram of the invention.
Fig. 3 is electrical structure block diagram of the invention.
Claims (2)
1. one kind can substitute the QR2S controller of QR2S control flow, it includes output end and master of the circuit by input isolation circuit
The input terminal for controlling circuit is connected, and the output end of governor circuit is connected with the input terminal of output amplifier, it is characterised in that: described
The input terminal of input isolation circuit can be using conventional master controller or remote controller signal.
2. one kind according to claim 1 can substitute QR2S control flow, and realize the controller of original function, feature
Be: the controller output directly controls major loop contactor, and simplified control route reduces manufacturing cost, eliminates peace
Full hidden danger improves the reliability of equipment.
