Description
Technical field
The present invention relates to mining site construction field, specially a kind of real-time drillhole inclination survey deviation correcting device.
Background technique
In coal industry production, coal and gas prominent is always the maximum hidden danger of Safety of Coal Mine Production, is directly threaten
The safety of miner.For this purpose, having carried out various researchs both at home and abroad, multinomial measure is also taken.It is pre- currently with drilling before adopting
Draw out methane, reduces gas pressure in coal rock layer, be still to prevent the most effective method of coal and gas prominent.
In recent years, as km directional drilling machine is in the successful popularization and application of the ground such as Shanxi, Shaanxi, Ningxia, Inner Mongol coal mine, coal
The transmission of mining drilling signal and measurement-while-drilling system are also gradually applied.But since drilling rod is not in directional drilling work progress
Rotation, the more common drilling process of deslagging situation is poor, easily the accidents such as generation bit freezing, burying, or even drilling rod locking can occur can not
Situations such as moving back brill cannot make measurement-while-drilling system Safe withdrawing, cause huge economic loss, so that the one-tenth porosity of directional drilling
It is greatly lowered.In this case, more advantageous using ordi-nary drilling machine progress rotary drilling construction technology drilling.But
When using common rotary drilling technological borehole, because there is no measuring system to carry out accurate measurement and positioning to it at present, often result in
There are relatively large deviations for actual borehole track and design drilling track.And firedamp taking-out discharging drilling construction is not in place, so that in coal seam
There is gas drainage under suction blind area, causes gas control hidden danger, the gas exceeding limit accident frequent occurrence in tunnelling and later period back production,
Even cause coal and gas prominent when serious, causes casualties and property loss.So research can be suitably used for common aperture and return
The inclinometer for turning drilling machine has very big significance.
The country is later relative to foreign countries about the research of inclinometer, since nineteen ninety, in order to meet China's related industry
To the needs of the measurements such as inclination angle, azimuth development, start various types of inclinometer system researches to foreign countries' production, improves
And the measuring system of production domesticization is had developed, produce wired measuring system and wireless measuring system.As Wired System for Inclination Measurement acquires
Data can intuitively reflect the variation characteristic inside tailings warehouse dam body, can acquire in real time, acquisition data it is accurate, acquire institute
It is smaller by environmental images.
Different according to inclinometer structure, inclinometer can be divided into stationary slope level and two kinds of sliding inclinometer.It is fixed
Formula inclinometer is mounted in inclinometer pipe, once it is determined that just not changing with regard to position, inclinometer measures the inclination of position
Angle variation；Sliding inclinometer can move in inclinometer pipe along tube wall according to measurement needs, can be to entire deviational survey hole back and forth
Measurement.But both typical inclinometers cannot be applied on the common slewing drilling machine of gas drilling.
With fields such as geotechnical engineerings, the continuous intensification of drilling depth is lengthened, and error also constantly increases, and the current country makes
Inclinometer and directional drilling machine are expensive mostly from external import.And external mine condition and domestic gas bearing
Situation has difference, it is difficult to be suitable for China's ground class boring work scene.And for architecture industry, advanced hole, the underground in tunnel
Pre-grouting hole, exploratory bore-hole, the construction of pile foundation and the petroleum industry in space etc., every profession and trade require one kind fast, just
It takes, real-time deviational survey and deviation correcting device.
Generally speaking, the existing real-time deviational survey deviation correcting device of drilling has the following deficiencies:
(1) existing drilling machine cannot carry out real time correction to drilling track during drilling in drilling, so that
Drilling is easy to happen deviation；
(2) existing drilling machine cannot measure positioning to physical location, the depth etc. of drilling, be unfavorable in drilling
Subsequent construction；
(3) existing drilling machine is when drill over long distances, since drilling rod cannot rotate, is easy to appear bit freezing, burying, no
It phenomena such as bar can be moved back, can not only delay being normally carried out for construction, also will cause huge economic loss.
Summary of the invention
In order to overcome the shortcomings of that prior art, the present invention provide a kind of real-time drillhole inclination survey deviation correcting device, the device
In drilling, the angle of drilling, track can be measured in real time, and in hole scattering, drilling track be carried out quick
It corrects, avoids the function of influencing to drill, meanwhile, it is capable to carry out rapid survey positioning to physical location, depth of drilling etc., avoid
Subsequent construction is influenced, in addition, the device can avoid the occurrence of card under the premise of guaranteeing that efficient over long distances, high quality drills
Brill, cannot move back phenomena such as bar at burying, can not only guarantee being normally carried out for construction, additionally it is possible to avoid economic loss, can have
