Description
A kind of fully electrically controlled well top driving mechanism, it belongs to a kind of drilling equipment, can be used for oil exploitation and geological prospecting etc.
Present drilling equipment drives the device that drilling rod rotates, and the patterns that are fixed in the drilling well wellhead platform that adopt in drilling process, do not move downward with drilling rod more.This driving method adds the stacks and the complicated operation of bit change more, thereby is replaced by the drilling well top-drive device gradually.Present existing well top driving mechanism, it uses driving head moving up and down to place the drilling rod top to drive the drilling rod rotation.In drilling process, move down with drilling rod.And when adding stacks, as long as the drill rod connector release, top driving device is risen up into boring tower top and can.The well top driving mechanism of development mainly contains two kinds now, and a kind of is fluid pressure drive device, and another kind is a direct-current driving device.They are to use hydraulic motor or dc motor to do power source respectively, directly drive drilling rod after slowing down by deceleration device and rotate.Use the liquefaction motor to drive, though driving moment is big, can adjust its driving moment, and the volume of hydraulic motor itself is little, in light weight.But, owing to need a cover hydraulic power unit and a control system, the power requirement of this hydraulic power unit very big (generally about 500 kilowatts), its volume is very big, can only be positioned over ground, guide to the boring tower top by high-pressure hose and link to each other with top driving device, and move up and down with it, its structure is quite heavy.Moreover hydraulic-driven is that constant force (or constant force square) drives, and low-speed characteristic is bad, can not adapt to the requirement of short-time overload.Hydraulic means is had relatively high expectations to hydraulic oil, and the field work condition makes to be needed often hydraulic oil to be filtered or changes.Since the above-mentioned shortcoming of hydraulic pressure top driving device, external now main development top electric drivor.For easily its work operating mode being controlled, for obtaining low-speed characteristic preferably, present electric driver all is to be power source with the dc motor, utilizes the variable working condition of dc motor and the power requirement that low-speed characteristic satisfies top driving device.But, when carrying out oil drilling, very high requirement of explosion proof is arranged.Commutating brush in the dc motor has had a strong impact on explosion-proof performance, must the very complicated shielding measure of utilization structure.And common direct current generator volume is bigger, and brush etc. are vulnerable parts, and a lot of maintenance issues are in use arranged.
The purpose of this utility model is a kind of fully electrically controlled well top driving mechanism of invention, and it has bigger driven at low speed torque factor, and control break operating mode easily, and brushless has explosion-proof performance preferably, and frame for movement is simple.
The utility model as shown in Figure 1.It has suspension ring 1, drill rod connector 2, reducer 3, motor field frame 4, stator 5, stator coil 6, rotor 7 and rotor bearing 8, it is characterized in that: the p-m rotor that rotor 7 is made for rare earth permanent-magnetic material, stator coil 6 is connected to variable ratio frequency changer supply convertor 9, standard industrial control 10 is arranged on rig floor, this standard industrial control 10 by the standard serial communication interface with can link to each other with the total central control computer 11 of miscellaneous equipment, in standard industrial control 10, be inserted with and link to each other with the control end of variable ratio frequency changer supply convertor 9 and its control adapter module of controlling 12.
Accompanying drawing 1 is a structural representation of the present utility model.
In the utility model, suspension ring 1, drill rod connector 2, reducer 3, motor field frame 4, stator 5, stator coil 6 can utilize the existing design of present existing direct current generator top-drive device, even can directly use existing equipment to reequip.Rotor 7 uses the rare earth permanent-magnetic material manufacturing.In use, after feeding the alternating current of certain frequency in the stator coil 6, form the magnetic field of a rotation in stator 5, the permanent magnetic field of the rotor 7 that this rotating excitation field and rare earth permanent-magnetic material are made interacts, thereby makes rotor 7 rotate.Rotatablely moving by after reducer 3 decelerations of rotor 7 drives drill rod connector 2 and rotates, and then drive the drilling rod rotation, finishes and creeps into function.In use, the operating mode that drilling rod drives is by controlling with the total central control computer 11 of miscellaneous equipment, when needs change to drive operating mode, central control computer 11 sent by the standard serial communication interface that gating links to each other with the control end of variable ratio frequency changer supply convertor 9 and to the address gating signal of its control adapter module of controlling 12.Standard industrial control 10 after receiving address gating signal, gating control corresponding adaptation module 12.After gating was good, central control computer 11 was given the pairing spinner velocity numerical value of driving operating mode that makes new advances, and is latched and conversion rear drive variable ratio frequency changer supply convertor 9 by control adapter module 12.Change the output frequency of variable ratio frequency changer supply convertor 9, thereby changed the operating mode of motor.
The utility model uses the rotor of rare earth permanent-magnetic material manufacturing to substitute the original coil wound rotor by the brush power supply, has not only removed brush-system easy to wear and sparking from, and its explosion-proof is good, safeguards simple.And, bigger driving moment is arranged under identical rotor size, and have the driven at low speed torque factor the same with direct current generator because the magnetic energy product and the remnant field intensity of the magnet that rare earth permanent-magnetic material is made are all very high.The output frequency of the central control computer control variable ratio frequency changer supply convertor that use can have, thus control drives operating mode.Control conveniently, also is to use complicated control strategy to lay the foundation.The rotor structure that rare earth permanent-magnetic material of the present utility model is made is simple, can realize higher driving power and rotating speed.
In the utility model, the p-m rotor that rotor 7 is made for rare earth permanent-magnetic material can be selected NdFeB material or ferrocerium boron material for use, can be all-in-one-piece, embedding a metal output shaft in inside, also can be that rare earth permanent-magnetic material is manufactured magnet, is fixed in the rotor of output shaft axle surface.
In the utility model, suspension ring 1, drill rod connector 2, reducer 3 etc. can utilize the ready-made design of existing direct current top driving device, or directly reequip with it.When Transform Type design, can utilize rare earth permanent-magnetic material to adapt to high-revolving characteristics, strengthen the speed reducing ratio of reducer.
The variable ratio frequency changer supply convertor 9 that uses in the utility model can be a cover rectifying device such as a controlled frequency inverter, and the structure such as the patent No. are that the patent or the patent No. of CN89214316 is the patent of CN89209067.Also can use the G5 series or the G7 series inverter of Japanese fuji company.
