Description of drawings
The invention will be further described below in conjunction with accompanying drawing and the specific embodiment:
Figure is the structural principle scheme drawing that uses a kind of main electromotor of the present invention.
The specific embodiment
Referring to accompanying drawing, the present invention will be described below in conjunction with the mine main electromotor, and it may further comprise the steps:
Step 1, in promoting control process, the one, one section constant-speed section of design before promoting initial acceleration, as the surveyed area that promotes electric current, use current sensor 6 to detect the current signal that promotes motor, the real-time input controller 5 of the current signal that is obtained converses the lifting current value by controller 5 according to current signal; If promote current value greater than the normal a certain specialized range that promotes current value, controller is made following control immediately: the mine hoist safety braking, and forbid automatic lift; If promote current value less than the normal a certain specialized range that promotes current value, controller can be judged the skip bucket of downward operation and not unstow, and makes following control immediately: the mine hoist safety braking, and forbid automatic lift; The 2nd, controller is definited time-lag the overcurrent judgement simultaneously to above-mentioned lifting current value and is judged that with inverse-time overcurrent overcurrent occurs in case promote electric current, just make following control immediately: mine hoist safety is braked, and forbids automatic lift.
After forbidding in the above-mentioned steps 1 promotes and remove, after skip bucket is raised a circulation, just allow to the skip loading material.
In the above-mentioned steps 2, also comprise the time of run of setting feeder by controller, control the carrying capacity in quantitative storehouse by the time of run of control feeder.
Aspect above-mentioned loading control, quantitatively the pressure magnetic in storehouse is weighed buy securities with all one's capital, overload promotes overweight the first line of defence as prevention, quantitatively in a single day buy securities with all one's capital in the storehouse, loading conveyor and feeder are just stopped transport, in case the overload signalizing activity is loading conveyor and feeder stoppage in transit not only, and restriction can only be loaded from the trend skip loading in gradation.In addition,, control carrying capacity, promote overweight defence line, second road thereby formed prevention by the time of run of control feeder because the feeding coal of feeder is relatively stable.
