Abstract
This invention relates to screw pile and machine combined structure including a power source controller, drill rod rotating sensor, drill rod shifting up and down sensor, frequency converter used in drill rod rotating sensor, and a frequency converter used in up and down pulling structure. Since the two structures are controlled by the converter, and rotating speed structure is adjusted to match the speed of up and down pulling structure, the oscillation of control system arisen from the after effect of wrapping connector driving system is eliminated effectively, and by setting the same starting time for two coverter, the out-of synchronization and shock to power source are overcome.
Description
Technical field
The present invention relates to helical burr ram stake machine, particularly helical burr ram stake machine link gear.
Background technology
China's utility model patent " helical burr ram stake machine " (patent No. ZL01240059.9) discloses a kind of helical burr ram stake machine scheme, and its structural representation is seen Fig. 3, and it is made up of haulage gear about frame 1, drilling rod 2, drill rod rotary mechanism, the drilling rod; Drill rod rotary mechanism and drilling rod up and down haulage gear are driven by separately power source respectively, and power source is a motor 10; The rotating mechanism of drilling rod is made up of the rotating mechanism motor and the reductor of drilling rod, and motor via reducer drives the drilling rod rotation, and rotating part motor and reductor are arranged in the unit head 6; Haulage gear is by traction electric machine 10 and running part are formed up and down about the drilling rod, running part is made up of hoist engine 5, wire rope 3 and assembly pulley 4, drilling rod up and down haulage gear be about two-way constraint haulage gear, thereby traction electric machine 10 drives unit head 6 by running part and drives drilling rod 2, and moving up and down of drilling rod 2 determined by haulage gear.Drill rod rotary mechanism and drilling rod are provided with link gear between the haulage gear up and down, link gear is made up of haulage gear power source controller, drilling rod turn-sensitive device 8, drilling rod upper and lower displacement sensor 9, power source controller is an Industrial Control Computer 11, the signal output part of sensor 8,9 connects with the signal input part of Industrial Control Computer, Industrial Control Computer 11 control frequency converters 13, frequency converter 13 control traction electric machines 10; Turn-sensitive device 8 is arranged in the unit head 6, and displacement transducer 9 is arranged on the frame.
Its link gear adopts electronic control mode, its schematic diagram is seen Fig. 4, operating principle is: measure helical burr ram stake machine drill bar rotary drive mechanism and drilling rod haulage gear displacement up and down respectively by rotary angle transmitter 8 and displacement transducer 9, satisfy the proportionate relationship of setting as both, then maintain the statusquo; Otherwise by the frequency of adjusting frequency converter 13 and then the speed of adjusting traction electric machine 10, make displacement relation between the two satisfy the proportionate relationship of setting by industrial control unit (ICU) 11.
In such scheme, when the motion of haulage gear about drill rod rotary mechanism and the drilling rod can not be satisfied the proportionate relationship of setting, industrial control unit (ICU) can instruct traction electric machine 10 to regulate the speed, because drilling rod haulage gear up and down is by flexible transmission mechanism transmissions such as chain or wire rope, make the action of adjustment in time not carry out and to be reflected on the sensor, and the certain hour that always lags behind, make controller reach a conclusion, adjustment amount is not enough, need further to strengthen adjustment amount, surpassed actual needs, thereby cause toning, cause new imbalance, so just can in control system, cause concussion, thereby cause drill rod rotary mechanism and drilling rod up and down the motion of haulage gear can not well satisfy the proportionate relationship of setting, make the control accuracy reduction.When band carries startup, drill rod rotary mechanism directly drives reductor by motor and drives the drilling rod rotation, start owing to belong to directly, can produce very big starting current on the one hand, power-supply system is impacted: on the other hand, drilling rod produces immediately and rotatablely moves, haulage gear generation synchronously moves up and down about requiring drilling rod, and haulage gear is moved up and down by flexible transmission mechanism drive such as chain or wire rope drilling rod by the Frequency Converter Control motor about the drilling rod, frequency converter is for reducing the impact to power supply, the general setting than long start-up time, add the lag time of flexible transmission mechanism, make drilling rod up and down haulage gear produce bigger hysteresis, coupling between the two more encounters difficulties, and is difficult to guarantee the proportionate relationship that requires.
Purpose of the present invention is: a kind of helical burr ram stake machine link gear is provided, regulates and control drill rod rotary mechanism and the drilling rod proportionate relationship between the haulage gear up and down better, control accuracy is improved greatly, and effectively slow down the impact to power supply.
For achieving the above object, solution of the present invention (Fig. 1 is seen in its structural representation) is: it comprises power source controller 11, drilling rod upper and lower displacement sensor 9, drilling rod turn-sensitive device 8, rotating mechanism frequency converter 12, rotating mechanism is controlled rotary drive motors 7 with frequency converter 12, haulage gear frequency converter 13, haulage gear is controlled traction electric machines 10 with frequency converter 13, keyboard, compositions such as display, its power source controller is an Industrial Control Computer 11, sensor 8,9 signal output part connects with the signal input part of Industrial Control Computer, Industrial Control Computer 11 control rotating mechanisms frequency converter 12 and haulage gear frequency converter 13, and rotating mechanism and haulage gear all adopt the peace river board VS-616G5 type frequency converter of day intrinsic safety river Co., Ltd. with frequency converter.
Below in conjunction with accompanying drawing its operating principle is described.
Fig. 1 is the embodiment of the invention 1 structural representation
Fig. 2 is the embodiment of the invention 1 a control section schematic diagram
Fig. 3 is former utility model embodiment 1 structural representation
Fig. 4 is former utility model embodiment 1 control section schematic diagram
As Fig. 2 is the embodiment of the invention 1 control section schematic diagram, the data that 11 pairs of turn-sensitive devices of power source controller, 8 each displacement transducer 9 transmit compare, if satisfy the proportionate relationship of setting, then maintain the statusquo, otherwise thereby power source controller 11 is adjusted the speed of rotating mechanism with the frequency adjustment rotating mechanism drive motors 7 of frequency converter 12, makes the drilling rod rotation and moves up and down and satisfy the proportionate relationship of setting.Because the transmission system of drill rod rotary mechanism is a rigidity, when system adjusted the speed of rotating mechanism, the instruction meeting was in time carried out and is reflected to simultaneously on the sensor, can not produce the hysteresis of former scheme, thereby reduced the concussion of control system, control accuracy is improved; On the other hand, because the motor of haulage gear is by Frequency Converter Control about drill rod rotary mechanism and the drilling rod, can be set both start-up times on request, thereby overcome the asynchrony phenomenon of former scheme two cover mechanisms when starting, and the basic shock problem that solves power supply.Like this, rotatablely moving and moving up and down of drilling rod can be satisfied the proportionate relationship of setting well, satisfies technological requirement.Set different frequencies by haulage gear with frequency converter 13, can change the drilling rod speed of haulage gear up and down, thereby realize the stepless speed regulation of rate of penetration.
