Described above is only the general introduction of technical solution of the present invention, in order to better understand the present invention
Technological means, and can be practiced according to the content of description, and the present invention's be upper in order to allow
State and can become apparent with other objects, features and advantages, below especially exemplified by preferred embodiment, and
Coordinate accompanying drawing, describe in detail as follows.
Accompanying drawing explanation
Fig. 1 is the control schematic diagram getting rid of soil series system in embodiments of the invention.
Fig. 2 is the control logic chart getting rid of soil series system in embodiments of the invention.
Detailed description of the invention
By further illustrate technological means that the present invention taked by reaching predetermined goal of the invention and
Effect, below in conjunction with accompanying drawing and preferred embodiment, it is as follows that the present invention is described in detail.
The invention provides a kind of rotary drilling rig, this rotary drilling rig has one and gets rid of soil series system, such as figure
Shown in 1, this get rid of soil series system include getting rid of soil signal generator 10, controller 20, proportioning valve 30,
Main pump 40 and unit head 50.Get rid of soil signal generator 10 to be connected with controller 20 signal, control
Device 20 is connected with proportioning valve 30 signal, and proportioning valve 30 is connected with main pump 40 signal, main pump 40
It is connected with unit head 50 signal；Get rid of soil signal generator 10 and get rid of soil for sending to controller 20
The commencing signal of operation, controller 20 receives after getting rid of the signal that soil signal generator 10 sends, profit
Control to flow through ratio by the mode of PWM (Pulse Width Modulation, pulse width modulation)
The size of the electric current of valve 30, makes the size flowing through the electric current of proportioning valve 30 change continually,
And make the aperture of main pump 40 can change according to the size of the electric current of passing ratio valve 30, thus
Control to flow through the size of the fluid flow of main pump 40, then affect the rotating speed of unit head 50, pass through
Earth in drill bit is thrown away by the inertia of frequently change and the earth of unit head 50 rotating speed.In this reality
Executing in example, controller 20 can be ECU (Electronic Control Unit, electronic control unit),
Proportioning valve 30 can be electricity proportional pressure-reducing valve, but is not limited.
Further, in order to avoid getting rid of when soil series system carries out and gets rid of soil operation, earth is got rid of in boring,
Also need to ensure that drill bit is in suitable position when carrying out and getting rid of soil operation, and bit location can be passed through
Perusal or confirmed by getting rid of the soil series mode that automatically determines of system.Soil series system is got rid of the most really in utilization
Determining in the mode of bit location, this gets rid of soil series system and also includes drill bit state harvester 60.Drill bit state
Harvester 60 is for gathering the current location information of drill bit, and passes it to controller 20,
Judged whether can carry out getting rid of soil operation according to the current location of drill bit by controller 20.In this reality
Executing in example, drill bit state harvester 60 includes bit location sensor 61 and boarding position encoder
62.Bit location sensor 61 can monitor the drill bit height relative to ground.At the present embodiment
In, set drill bit with the ground numerical value that time concordant, bit location sensor 61 obtains as zero, work as brill
Head is when stretching in punching, the numerical value that bit location sensor 61 obtains on the occasion of, when drill bit is on ground
The numerical value that time on face, bit location sensor 61 obtains is negative value.Boarding position encoder 62 is permissible
The deflection angle of monitoring drill bit place drilling rod.
As in figure 2 it is shown, when rotary drilling rig utilize above-mentioned get rid of soil series system carry out getting rid of soil operation time, its
Method mainly comprises the steps:
First press and get rid of soil signal generator 10, make control system according to getting rid of soil signal generator 10
Trigger action send the commencing signal carrying out getting rid of soil operation to controller 20.
Controller 20 is adopted by bit location sensor 61 after receiving the commencing signal getting rid of soil operation
Collection drill bit is relative to the height on ground, and is gathered drill bit place brill by boarding position encoder 62
The deflection angle of bar, and the information collected is judged.
When the numerical value of bit location sensor 61 correspondence be on the occasion of or the deflection of drill bit place drilling rod
Angle (numerical value is between 0～360 degree) is equal to the angle at drilling rod place during the punching of systemic presupposition,
Namely when drill bit locates below ground level or drill bit is positioned at punch position, get rid of soil series system and can not carry out getting rid of soil
Operation.
When the numerical value of bit location sensor 61 correspondence is negative value and the deflection angle of drill bit place drilling rod
When degree is not equal to the deflection angle of systemic presupposition, namely drill bit is positioned on ground and drill bit deviation is beaten
During hole site, controller 10 utilizes the mode of pulse width modulation to control to flow through the electricity of proportioning valve 30
Stream size is periodically cut between maximum current and the minimum current two states set continually
Change, and make main pump 40 can change the big of main pump aperture according to the size of current of passing ratio valve 30
Little, thus control to flow through the size of the fluid flow of main pump 40, then affect turning of unit head 50
Speed, is thrown away the earth in drill bit by the frequent transitions of unit head 50 rotating speed and the inertia of earth.
In the present embodiment, the persistent period of maximum current and the persistent period of minimum current are all but do not limit
In 100ms.The changing value of the electric current of passing ratio valve 30 and variation pattern can pass through controller
20 preset.
In sum, the present invention controls main by the size of current being frequently changed passing ratio valve
The size of pump aperture changes continually, then makes the rotary speed of unit head become continually
Change the purpose reaching to get rid of soil.The frequent change of unit head rotary speed, can quickly and efficiently by
Earth throws away from drill bit.Do not change the direction of rotation of unit head owing to this gets rid of soil series system, thus keep away
Exempt from the impact that hydraulic system is caused by unit head rotating.Further, it is not required to due to unit head
Rotating switching to be carried out, therefore has only to a button and just can control to get rid of the unlatching of soil operation,
Turn, this reduces the burden of operator.
The above, be only presently preferred embodiments of the present invention, and the present invention not makees any shape
Restriction in formula, although the present invention is disclosed above with preferred embodiment, but and it is not used to limit
Determining the present invention, any those skilled in the art, without departing from technical solution of the present invention model
In enclosing, when the technology contents of available the disclosure above makes a little change or is modified to equivalent variations
Equivalent embodiments, as long as being without departing from technical solution of the present invention content, according to the skill of the present invention
Any simple modification, equivalent variations and the modification that above example is made by art essence, the most still belongs to
In the range of technical solution of the present invention.
