Piler is a kind of tunnel commonly used weight-lifting equipment.Existing piler mainly comprises loading platform, electrical control cubicles, operating unit, column, pallet fork, lifting mechanism, walking roller box, the operation actuating device that is connected with operating unit and the actuating device that hoists that is connected with lifting mechanism.Existing piler adopts the actuating device that is comprised of asynchronous motor, retarder to drive usually.Practice shows, adopt this kind actuating device can bring following problem: one, because 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 piler low, starting is not steady, heavy-load start is difficult.Its two 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 piler high, maintenance capacity is large, accuracy of positioning is low.Based on this, be necessary to invent a kind of brand-new piler, existing piler 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 accuracy of positioning.
Summary of the invention
Existing piler 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 accuracy of positioning for the utility model, and a kind of permanent magnet direct-drive piler is provided.
The utility model is to adopt following technical scheme to realize: the permanent magnet direct-drive piler comprises loading platform, electrical control cubicles, operating unit, column, pallet fork, lifting mechanism, walking roller box, the operation actuating device that is connected with operating unit and the actuating device that hoists that is connected with lifting mechanism; The described actuating device that hoists comprises permanent magnet direct-drive lifting motor, back-up ring, hoist brake and motor base; The output shaft of permanent magnet direct-drive lifting motor is connected with the cylinder of lifting mechanism; The casing of permanent magnet direct-drive lifting motor is installed on the motor base; Back-up ring is installed on the rear end of permanent magnet direct-drive lifting motor; Hoist brake is installed on the axle drive shaft of lifting mechanism; Described operation actuating device comprises permanent magnet direct-drive operation motor, operation brake and axle drive shaft; The output shaft of permanent magnet direct-drive operation motor is connected with the walking roller box by axle drive shaft; Operation brake is installed on the axle drive shaft of operating unit; The power input of the power input of permanent magnet direct-drive lifting motor and permanent magnet direct-drive operation motor all is connected with frequency converter.
During work, the cylinder that the permanent magnet direct-drive lifting motor drives lifting mechanism is rotated, and then the drive lifting mechanism is finished the action that hoists.Lifting mechanism hoisted to material with loading platform, electrical control cubicles, column, pallet fork, the common cooperation of walking roller box.Can carry out speed governing to the permanent magnet direct-drive lifting motor by frequency converter, and then adjust the lifting velocity of material.Can brake lifting mechanism by hoist brake.Permanent magnet direct-drive operation motor is rotated by drive shaft walking roller box, and then the drive operating unit is finished the walking action.Operating unit transported material with loading platform, electrical control cubicles, column, pallet fork, the common cooperation of walking roller box.Can move motor to permanent magnet direct-drive by frequency converter and carry out speed governing, and then adjust the travelling speed of material.Can brake operating unit by operation brake.Based on said process, compare with existing piler, the standby following advantage of permanent magnet direct-drive stack-building equipment described in the utility model: one, adopt permanent magnet direct-drive lifting motor and permanent magnet direct-drive operation motor to substitute asynchronous motor, move the characteristics such as the electric motor starting torque is large, power factor is high, efficient is high, electric energy loss is little, the interruption of service rate is low based on permanent magnet direct-drive lifting motor and permanent magnet direct-drive, speed-regulating function in conjunction with frequency converter, realized the slow start of piler, improved thus drive efficiency, realized smooth starting, and made heavy-load start become easy.Its two, saved retarder, the various faults of having avoided thus retarder under the state of working long hours, to occur, thereby reduced the parts fault rate of piler, reduced maintenance capacity, improved accuracy of positioning.Based on above-mentioned 2 points, permanent magnet direct-drive piler described in the utility model passes through in conjunction with the own characteristic of permanent magnet direct-drive electrical motor and the speed-regulating function of frequency converter, realized the gearless permanent-magnet synchronous frequency conversion of piler is driven, solved effectively thoroughly thus that existing piler 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 accuracy of positioning.
The utility model efficiently solves that existing piler 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 accuracy of positioning, is applicable to store the large-tonnage material.
