Description
Technical field
The utility model discloses a set of mine flight conveyer load to monitor early warning system, belongs to automatic control technology neck
Domain.
Background technology
China's gently inclined thick coal seam, super high seam are distributed more widely, rich reserves, and coal seam thickness is generally 5~10m, individually
Thickness can reach 20m, currently use Longwall Top Coal Caving Method, and mining height of coal mining machine is generally 2.8m, and caving radio is 1 ﹕ 3,
The transporting coal amount that i.e. fully mechanized coal face rear portion drag conveyor is undertaken accounts for the 3/4 of whole yield.It is comprehensive during actually producing coal
Put working face rear portion scratch board conveyor and put coal amount and be not easy to be monitored, particularly after heavy duty parking, easily cause starting difficulty again.
Utility model content
The utility model deficiency existing for prior art, devise a set of load monitoring early warning system, the set system
Rear portion drag conveyor motor operating current is gathered, so as to reflecting real time execution load, imminent load is transfinited and made
Early warning, to control coal amount of putting, reduce load conveyor, reserve equipment starting capability, avoid after stopping in emergency, kill scraper plate transport
Machine.
In order to solve the above technical problems, the utility model use technical scheme be：Mine flight conveyer load is supervised
Depending on early warning system, including：Mining programmable control cabinet, the first mining soft starter, the second mining soft starter and mining alarm
Device；Described mining programmable control cabinet is by PLC, display, keyboard, intrinsic safety electric source, input/output intrinsic safety division board group
Into PLC is connected with display, keyboard, intrinsic safety electric source, input/output intrinsic safety division board respectively by wire, input/output sheet
Peace division board is connected with the first mining soft starter, the second mining soft starter and mining warning device respectively by wire, the
One mining soft starter is connected by wire with handpiece of scraper conveyer motor, and the second mining soft starter passes through wire and scraper plate
Conveyer tail motor is connected.
Further, described mining warning device or be mining electric bell, or be mining alarm lamp, or be mining acousto-optic report
Alert device.
Further, described mine audible-visual annunciator includes speech control module, loudspeaker, indicator lamp；Voice command
Module is connected with loudspeaker, indicator lamp respectively by wire.
Further, the first mining soft starter, the second mining soft starter are transmitted soft using MODBUS communication modes
The current signal of starter operation.
The utility model mine flight conveyer load monitoring early warning system apply on drag conveyor, have below compared with
Positive effect：
1st, system utilizes modern communication technology, reliably realizes the monitoring and control of the change of drag conveyor running current,
Load change situation is prejudged, display, the verbal announcement of ocular and clear can be carried out.
2nd, system can not only monitor scrapper conveyor running current in real time, may also display working voltage, running status, failure letter
The parameters such as breath, log.
3rd, drag conveyor running current, load anticipation are all shown in the form of animation, clear.
4th, degree of integration height is automated, System Working Principle is as follows：System is received from soft by the RS485 mouths on PLC
The communication signal of starter, display rear portion scraper plate feeder motor head, tail real time execution parameter, when actual motion electric current is less than
During the load super-limit prewarning electric current of setting, system does not perform early warning, and display is shown " normal "；When running current is more than setting
Early warning electric current, now, system carry out early warning delay（It is delayed adjustable）, display shows " early warning countdown "；Countdown does not complete
When, electric current is dropped to below early warning electric current, and countdown terminates, and display is shown " normal "；When running current is more than the pre- of setting
Alert electric current, and after early warning countdown, system performs early warning output, display is shown " early warning ".Audible-visual annunciator flashes, and sends
" load will overload " voice message, while electric bell, alarm lamp are according to the 5s that works, stopping 5s time interval continuous firing.
In this case, drag conveyor operative employee, which should suspend, puts coal or coal mining, mitigate load, running current is gradually reduced.Treat operation electricity
After stream is less than early warning electric current, early warning releases, and returns to normal production.In the case where load early warning exports, electric current continues to increase, and surpasses
Cross the early warning protective current of setting（After now stopping, starting capability surplus capacity is left）, system performs early warning protection, and display shows
Show " protection countdown ", audible-visual annunciator flicker, send " overload, will stop " voice message, while electric bell, alarm lamp
According to the 5s that works, stopping 5s time interval continuous firing.If electric current declines, less than protective current and more than the early warning electricity of setting
During stream, de-preservation countdown, into early warning countdown period.If electric current continues to increase, after protection countdown terminates, system is held
Row load transfinites protection, and output drag conveyor soft starter starts block signal, stops rear portion drag conveyor, and display shows
Show " protection ", audible-visual annunciator flicker, send " overload has stopped " voice message, while electric bell, alarm lamp are wholly off
Work.Press SR, system reset, releasing load is transfinited error protection, and unblock drag conveyor soft starter, which starts, to be closed
Lock signal, it is allowed to started again.
5th, it is safe and reliable, operate steadily：The control signal and signal of communication of soft starter, mining electric bell, mining alarm lamp,
The transmission signal of mine audible-visual annunciator by the input/output intrinsic safety division board in mining programmable case realize intrinsic safety every
From securely and reliably.
