Embodiment
As shown in figure 1, drag conveyor frequency changing regulating speed control apparatus of the present invention, including mine flameproof and intrinsic safety type control
Case 1 processed, the mine flameproof and intrinsic safety type control cabinet 1 are internally provided with central controller 2 and data communication module 3, institute
Central controller 2 is stated with data communication module 3 by wire to be connected；
The signal input part of the data communication module 3 is connected with coal site sensor 4, and the data communication module 3 passes through industry
The communications cable is bi-directionally connected with frequency converter 5.
The frequency converter 5 includes head frequency converter 6 and tail frequency converter 7, the head frequency converter 6 and the phase of head motor 8
Even, tail frequency converter 7 is connected with tail motor 9.
The inside of the head frequency converter 6 and tail frequency converter 7 is also respectively provided with current sensor.
The control terminal of the central controller 2 is also associated with Self-resetting flame-proof switch 10.
The data communication module 3 is also connected by the communications cable with programming monitoring computer 11.
The industrial communication cable is the bus cable with CAN serial communication protocols.
The model KXJ3-127 of the mine flameproof and intrinsic safety type control cabinet 1.
The plastic packaging of Self-resetting flame-proof switch 10 is provided with flame proof control button in switch enclosure, and the Self-resetting is prevented
The model LA5821-1 of voltage flame proof switch 10.
The present invention is provided with mine flameproof and intrinsic safety type control cabinet 1 in the Handpiece Location of equipment train, described mining
Flameproof intrinsically safe control cabinet 1 is internally provided with individual chips as central controller 2, and possesses programing function, can
Threshold value setting, pattern adjustment are carried out to it by programming monitoring computer 11；The data communication module 3 can receive coal
The motor running current data that coal position data that level sensor 4 collects, current sensor collect, and by gathered data
It is sent to central controller 2 to be handled, on the one hand central controller 2 can feed back gathered data during processing data
Computer 11 is monitored to programming, the adjustment signal after processing is on the other hand sent to frequency converter by data communication module 3 again
5, frequency converter 5 is made self-adapting frequency conversion.
During frequency converter is controlled, mine flameproof and intrinsic safety type control cabinet 1 only sends control frequency to frequency converter 5
Signal, do not send start close frequency converter signal, even if frequency converter 5 does not receive corresponding control signal, can also be about to certainly
Working frequency is recovered to 50Hz to run.
In signals transmission, when head frequency converter 6, tail frequency converter 7 are arranged to master-slave cascade operational mode, in
Entreat controller 2 only need to carry out data exchange with head frequency converter 6；When head frequency converter 6, tail frequency converter 7 are independently run
When, central controller 2 need to carry out data exchange simultaneously with head frequency converter 6, tail frequency converter 7.
To make the running frequency of frequency converter 5 adaptively be adjusted according to the coal position data collected, under automatic speed regulation state,
During mine flameproof and intrinsic safety type control cabinet 1 feeds back to the motor running current collected and stripper cell coal-heig ht in bunker
Controller 2 is entreated, the threshold value that central controller 2 is set by internal preprogramming carries out computing, and frequency variation signal is transferred into change
Frequency device 5, now the frequency converter of frame head and tail be adjusted to given working frequency, equipment is run under low consumption state, it is given
Upper operational frequency limit and lower limit can freely be set according to work on the spot environment.
Under the variable frequency regulating speed control of the present invention, the operational factor change procedure of drag conveyor is as shown in Figure 2；Whole fortune
Row process is divided into five stages, the i.e. start-up course of stage one, the Control of Frequency Control Process of stage two, the high current full speed process of stage three,
The high coal position full speed process of stage four, the manual intervention process of stage five；
In the stage one, motor working frequency is the maximum given frequency of frequency converter；
In the stage two, the no-load current of motor corresponds to the minimum given frequency of frequency converter, when motor is run most
High current corresponds to the maximum given frequency of frequency converter, carries out linear speed regulation；
In the stage three, motor running current exceedes maximum current, no matter now coal position height, the given frequency of frequency converter
Maximum given frequency will be adjusted to；
In the stage four, motor running current is less than maximum current, and when coal position exceedes highest coal position, frequency converter gives
Frequency will be adjusted to maximum given frequency, and be maintained in all stage, can be by coal potential drop as little as below highest coal position；
In the stage five, motor running current is less than maximum current, and coal position has close to highest coal position and gushes coal danger, now
By manual operation explosion-proof control button Self-resetting flame-proof switch box, the given frequency of frequency converter is adjusted to maximum given frequency
Rate, and maintained in all stage, it can avoid gushing coal.
During automatic speed regulation, if drag conveyor is under low-speed run state, possible moment occurs head and gushes coal
Phenomenon, now need, by manual operation Self-resetting flame-proof switch 10, to make drag conveyor full speed running in short-term, then again
Into automatic debugging mode, indirect labor's control, which can be reduced effectively, gushes the generation of coal phenomenon, avoids device damage.
