Description
Technical field
The utility model relates to scraping transporter, specifically a kind of mining permanent magnet direct-drive scraping transporter.
Background technology
Scraping transporter is the transportation device commonly used of coal face.Existing scraping transporter adopts the actuating device that is comprised of flame-proof type asynchronous motor, fluid coupling, retarder to drive usually.Practice shows, adopt this kind actuating device can bring following problem: one, because flame-proof type asynchronous motor ubiquity detent torque is little, power factor is low, efficient is low, electric energy loss is large, interruption of service rate high, cause the drive efficiency of scraping transporter low, starting is not steady, heavy-load start is difficult.They are two years old, because the faults such as bearing failure, power fluid seepage, fusible plug fusing, blade are broken appear in fluid coupling easily under the state of working long hours, simultaneously because the faults such as bearing failure, oil sealing leakage of oil, gear wear appear in retarder easily under the state of working long hours, cause the parts fault rate of scraping transporter high, maintenance capacity is large, conveying efficiency is low.Based on this, be necessary to invent a kind of brand-new scraping transporter, existing scraping transporter drive efficiency is low to solve, starting is not steady, heavy-load start is difficult, the parts fault rate high, maintenance capacity is large and the low problem of conveying efficiency.
Summary of the invention
Existing scraping transporter drive efficiency is low in order to solve, starting is not steady, heavy-load start is difficult, the parts fault rate high, maintenance capacity is large and the low problem of conveying efficiency for the utility model, and a kind of mining permanent magnet direct-drive scraping transporter is provided.
The utility model is to adopt following technical scheme to realize: mining permanent magnet direct-drive scraping transporter comprises headstock, sprocket wheel, connection poppet, chain, scraper plate, chute and the actuating device that is connected with sprocket wheel; The wheel shaft two ends of sprocket wheel are supported in respectively on the biside plate of headstock; Connect the outer wall that poppet is installed on a side plate of headstock; The sprocket of chain and sprocket wheel is intermeshing; Scraper plate fastens on chain, and scraper plate is between the biside plate of headstock; The front end of chute docks mutually with the rear end of headstock; Described actuating device comprises flame-proof mine low frequency triphase synchronous motor; The casing of flame-proof mine low frequency triphase synchronous motor is installed on and connects on the poppet; The output shaft of flame-proof mine low frequency triphase synchronous motor is connected with wheel shaft one end of sprocket wheel; The power input of flame-proof mine low frequency triphase synchronous motor is connected with frequency converter.The number of the number of described sprocket, the number of chain, scraper plate all is decided according to the actual requirements.The structure that is connected to the easy realization of those skilled in the art between the output shaft of described flame-proof mine low frequency triphase synchronous motor and the wheel shaft of sprocket wheel can have the various structures distortion.
During work, the coal of coal face extraction falls between the biside plate of headstock, flame-proof mine low frequency triphase synchronous motor drive sprocket is rotated, sprocket wheel drives the chain straight-line motion that circulates, chain and then drive scraper plate and carry out straight-line motion is pushed to chute with the coal between the headstock biside plate and is transported by scraper plate.Can carry out speed governing to flame-proof mine low frequency triphase synchronous motor by frequency converter, and then adjust the travelling speed of coal.Based on said process, compare with existing scraping transporter, mining permanent magnet direct-drive scraping transporter described in the utility model possesses following advantage: one, adopt flame-proof mine low frequency triphase synchronous motor to substitute the flame-proof type asynchronous motor, large based on flame-proof mine low frequency triphase synchronous motor detent torque, power factor is high, efficient is high, electric energy loss is little, the characteristics such as the interruption of service rate is low, speed-regulating function in conjunction with frequency converter, realized the slow start of scraping transporter, improved thus drive efficiency, realized smooth starting, and made heavy-load start become easy.Its two, saved fluid coupling, retarder, the various faults of having avoided thus fluid coupling, retarder under the state of working long hours, to occur, thereby reduced the parts fault rate of scraping transporter, reduced maintenance capacity, improved conveying efficiency.Based on above-mentioned 2 points, mining permanent magnet direct-drive scraping transporter described in the utility model passes through in conjunction with the own characteristic of flame-proof mine low frequency triphase synchronous motor and the speed-regulating function of frequency converter, realized the gearless permanent-magnet synchronous frequency conversion of scraping transporter is driven, solved effectively thoroughly thus that existing scraping transporter drive efficiency is low, starting not steadily, heavy-load start is difficult, the parts fault rate high, maintenance capacity is large and the low problem of conveying efficiency.
The utility model efficiently solves that existing scraping transporter drive efficiency is low, starting not steadily, heavy-load start is difficult, the parts fault rate high, maintenance capacity is large and the low problem of conveying efficiency, is applicable to coal face.
