Step 5, whether detection has stops the signal that unit head cruises and creeps into, and if so, stops cruising and creeping into according to control Data Control unit head, if not, goes to execution step 4.
The method that the embodiment of the present invention provides can gather and the operation signal of storage operation device to unit head, then according to the aperture of banked direction control valves in the automatic oil circuit control of data of storage, and then unit head is controlled automatically, realize automatic imitation operator and control the operation that unit head creeps into, so that in unit head drilling process, reduce operator's operating time, reduce operator's labour intensity, alleviate the long-time fatigue strength that operation causes repeatedly.
Take below adopt unit head that the embodiment of the present invention provides to cruise to realize the unit head rotary drilling rig that creeps into function that cruises be example to drilling method, the method above steps is elaborated.
Step 1, starts.This unit head drilling method that cruises starts to carry out, and can open and the switching device that creeps into function that stops cruising is realized by being specifically designed to of arranging on rotary drilling rig, and also can be realized by other modes, and the present invention does not limit this.
Step 2, one group of operation signal when gathering described operating means described unit head being controlled.
Operation signal when acquisition operations device operates unit head, is the process that this method " study " operating means is controlled unit head, for control unit head cruises to creep into, provides the basis of controlling data.In rotary drilling rig boring procedure, especially in interstage of boring procedure, in the definite situation of geological conditions, the operation that unit head creeps into is all (as the record in background technology) being cycled to repeat conventionally, and various operations are all regular, therefore, these operations can be collected and cruise and creep into for controlling unit head.
Whether this step 2 can also specifically be preferably: detect and by operating means, unit head is controlled, if so, start the operation signal of acquisition operations device when unit head is controlled, if not, point out by operating means unit head is controlled, and repeat this step 2.This preferred version can be after this method starts, first confirm whether operating means is being controlled unit head, and confirming on the basis of "Yes" operation signal collection, carry out " study ", otherwise, alert is crept into controlling unit head by operating means, creeps into make " demonstration " for cruising.
The operating means of controlling unit head in rotary drilling rig is generally operating grip, therefore, can detect the action of operating grip by a plurality of sensors that are connected with operating grip are set, and then realize the operation signal of acquisition operations device.
It should be noted that, the operation signal described in the method that the embodiment of the present invention provides preferably includes pressurization signal and the speed controling signal while controlling unit head by operating means, and according to this operation signal, controls pressurization and the rotating speed of unit head.At unit head, cruise in drilling process, can not consider unit head to carry out floating control, but keep the unit head can be according to boring situation free floating, so operation signal can not comprise and controls the unsteady signal of unit head.Certainly, can comprise floating control signal in other embodiments, the present invention does not limit this yet.
In addition, " one group " operation signal described herein is intended to explanation, when operating means is controlled unit head boring, all need to carry out a series of action and realize, and for specific soil layer or rock stratum, these actions is repetition mostly; For example, in certain drilling operation, operating personnel need to carry out following control operation by operating means:
(1) applying plus-pressure is F1, and controlling unit head rotating speed is r1;
After (2) 3 minutes, the plus-pressure applying changes F2 into, and unit head rotating speed changes r2 into;
After (3) 1 minutes, the plus-pressure applying changes F3 into, and unit head rotating speed changes r3 into; And continue 5 minutes;
Then, then continue from (1), back and forth carry out the operation of (1), (2), (3).Now just will (1), (2), the operation of (3) and the sequencing of each operation and the time interval as " one group " operation signal, intactly collect use after staying.
Step 3, stops the operation signal of acquisition operations device, the operation signal having gathered is converted into the control data of digital signals format, and stores this control data.
