The driving device of the permanent-magnet frequency-conversion belt conveyer comprises a conveyer belt, and a driving device connected with a rotary drum of the belt conveyer; the driving device comprises a permanent-magnet synchronous motor; an output shaft of the permanent-magnet synchronous motor is connected with the rotary drum of the belt conveyer; and a power input end of the permanent-magnet synchronous motor is connected with a frequency converter. According to the driving device, the characteristics of the permanent-magnet synchronous motor and the speed regulating function of the frequency converter are combined, the gearless permanent-magnet synchronous frequency-conversion driving to the belt conveyer can be realized, so that the problems that when the existing driving device is adopted for driving the belt conveyer, the driving efficiency is low, the starting is not stable, the driving device is difficult to start when in heavy load, and the belt conveyer is high in failure rate can be solved effectively, and the belt conveyer is suitable for the driving of the underground belt conveyer.
Description
Technical field
The present invention relates to the belt feeder actuation techniques, specifically is a kind of permanent magnetism frequency conversion belt feeder actuating device.
Background technology
Belt feeder (belt conveyer) is mainly used under the coal mine, is the unique transportation device between down-hole one line extractive equipment and the big lane coal master belt.At present, belt feeder is mainly driven by the actuating device that asynchronous motor, fluid coupling, retarder are formed.The problem that this kind type of drive is brought is: one, because asynchronous motor self is intrinsic, cause that drive efficiency is lower, starting not steadily, heavy-load start is difficult.Two, owing to fluid coupling, retarder damage under the state of working long hours easily, cause the belt feeder fault rate higher, and then influence downhole production efficient.Based on above-mentioned 2 points, be necessary to invent a kind of brand new belt feeder actuating device, drive efficiency is lower when having actuating device driving belt machine now with the solution employing, starting is not steady, difficult, the belt feeder fault rate problem of higher of heavy-load start.
Summary of the invention
Drive efficiency was lower when the present invention had actuating device driving belt machine now in order to solve employing, starting is not steady, difficult, the belt feeder fault rate problem of higher of heavy-load start, and a kind of permanent magnetism frequency conversion belt feeder actuating device is provided.
The present invention adopts following technical scheme to realize: permanent magnetism frequency conversion belt feeder actuating device, comprise belt feeder and with the cylinder bonded assembly actuating device of belt feeder; Said actuating device comprises permasyn morot; The output shaft of permasyn morot is connected with the cylinder of belt feeder; The power input of permasyn morot is connected with frequency converter.
During work, the cylinder that permasyn motor direct connects belt feeder drives, and can carry out speed governing to permasyn morot through frequency converter, and then the rotating speed of adjustment belt feeder.Through said process, permanent magnetism frequency conversion belt feeder actuating device of the present invention has been realized the gearless permanent-magnet synchronous frequency conversion of belt feeder is driven.Compare with existing type of drive; The gearless permanent-magnet synchronous frequency conversion drives possesses following advantage: one, adopt permasyn morot to substitute asynchronous motor, based on the intrinsic characteristics of permasyn morot self, in conjunction with the speed-regulating function of frequency converter; Realized the slow start of belt feeder; Improved drive efficiency thus, realized smooth starting, and made heavy-load start become easy.Two, saved fluid coupling, retarder, avoided thus causing belt feeder to break down, thereby effectively reduced the fault rate of belt feeder, guaranteed the production under the coal mine because of fluid coupling, retarder damage.Based on above-mentioned 2 points; Permanent magnetism frequency conversion belt feeder actuating device of the present invention is through the own characteristic of combination permasyn morot and the speed-regulating function of frequency converter; Realized the gearless permanent-magnet synchronous frequency conversion of belt feeder is driven, solved effectively thoroughly thus when adopting existing actuating device driving belt machine that drive efficiency is lower, starting not steadily, difficult, the belt feeder fault rate problem of higher of heavy-load start.
Further, also comprise flange; The casing of permasyn morot is fixed on the frame of belt feeder through flange.Flange has made things convenient for the installation between the frame of permasyn morot and belt feeder, and has saved the set-up time.
Further, the pole span of permasyn morot is 9/8 groove or 6/5 groove or 3/2 groove.Adopt above-mentioned pole span can further improve the drive efficiency of permasyn morot, and then improve the drive efficiency of belt feeder.
The present invention is through the own characteristic of combination permasyn morot and the speed-regulating function of frequency converter; Realized the gearless permanent-magnet synchronous frequency conversion of belt feeder is driven; Efficiently solve when adopting existing actuating device driving belt machine that drive efficiency is lower, starting not steadily, difficult, the belt feeder fault rate problem of higher of heavy-load start, be applicable to the driving of belt feeder under the coal mine.
