Abstract
The invention relates to a hollow cable type directed water conveying device. In the directional drilling of a coal mine underground tunnel and the controlled directional drilling of geology, a measuring system during drilling is a necessary tool for continuously monitoring the track of a drilling hole and timely correcting deviation. In the prior art, the water conveying device only can provide a washing medium to the inner part of a drilling rod but can not transmit a bottom hole measuring signal. The hollow cable type directed water conveying device has the following structure: the inner cavity of the existing directed water conveying device is provided with a hollow cable device which consists of a conducting wire, a probe needle, a probe head, a spring, a fixing bolt and a diameter-changing spring; the probe needle is fixed in the probe head by the spring and the fixing bolt; the probe head is provided with the diameter-changing spring; the probe needle is connected with a fast wiring column which is arranged at the other end of the directed water conveying device through the conducting wire; the diameter-changing spring is connected with the female connecting head of a hollow cable type large through hole drilling rode of an inner circular conical surface; and the fast wiring column is connected with a hole opening controller. The hollow cable type directed water conveying device can safely and reliably realize the wire measurement during drilling, and can simultaneously meet the requirements of two drilling technologies of the drilling with a bottom hole assembly drilling tool and the drilling with a bottom hole motor.
Description
Technical field
The present invention relates to a kind of directed water feeder with measurement while drilling function, is the directed water feeder of the logical cable formula in a kind of center specifically.
Technical background
Under the coal mine in tunnel directional drilling and the geology controlled directional drilling, measurement-while-drilling system is continuous monitoring drilling track, the timely necessary tool of rectifying a deviation.In prior art, water feeder can only provide scouring media to drilling rod inside, can not transmission hole at the bottom of measuring-signal.
Summary of the invention
Technical problem solved by the invention provide a kind of can safety, reliably, the directed water feeder of the logical cable formula in the center of measuring-signal at the bottom of the transmission hole fast.
For solving above-mentioned technical problem, the technical scheme that the present invention takes:
The present invention includes joint, back-up ring, outer tube, axle, sheath, joint is connected by axle with outer tube, between outer tube and the axle back-up ring is set, one end of outer tube is provided with sheath, constitute directed water feeder, its special character is: the inner chamber of described directed water feeder is provided with the logical cable device in center, and it comprises lead, probe, probe, spring, holding screw and Spring capable of diameter varying, probe is fixed on probe inside by spring and holding screw, and Spring capable of diameter varying is set on the probe; Described probe is connected by lead with the fast-wiring post that is arranged on the directed water feeder other end, and Spring capable of diameter varying is connected with the female joint of the logical cable formula large through-hole drilling rod in center of internal conical surface, and the fast-wiring post is connected with the aperture controller.
Above-mentioned lead, probe, probe sheath are provided with insulation sleeve.
The logical cable device in above-mentioned center is arranged on the axis direction of directed water feeder by fast-wiring post and sheath.
Compared with prior art, beneficial effect of the present invention:

Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, the present invention includes joint 2, back-up ring 3, outer tube 4, axle 5, sheath 6, the center leads to cable device, the logical cable device in center comprises lead 7, probe 8, probe 9, spring 10, holding screw 11 and Spring capable of diameter varying 12, joint 2 is connected by axle 5 with outer tube 4, between outer tube 4 and the axle 5 back-up ring 3 is set, one end of outer tube 4 is provided with sheath 6, constitute directed water feeder, the logical cable device in center is arranged on the inner chamber of directed water feeder, probe 8 is fixed on probe 9 inside by spring 10 and holding screw 11, spring 10 has certain pre compressed magnitude, when probe 8 and lead 7 wearing and tearing cause after its length shortens, spring 10 is compensation automatically, guarantees that probe 8 and lead 7 keep in touch state, lead 7, probe 8, probe 9 is arranged with insulation sleeve.
The logical cable device in center is arranged on the axis direction of directed water feeder by fast-wiring post 1 and sheath 6.
The directed water feeder of the logical cable formula in center is connected with the logical cable formula drilling rod in center by the screw thread of front end, and measuring-signal passes through in Spring capable of diameter varying 12 input leads 7 at the bottom of the hole that drilling rod is exported, and by fast-wiring post 1 signal is exported to the aperture controller.
No matter whether the directed water feeder of the logical cable formula in center drilling rod when being connected with the logical cable formula drilling rod in center turns round the equal lead 7 and fast-wiring post 1 transfixion that can guarantee water feeder, during the drilling rod revolution, sheath 6, probe 9 and probe 8 are all along with drilling rod turns round together, but lead 7, fast- wiring post 1 and 2 transfixions of joint, so have relative rotary motion between probe 8 and the lead 7, after probe 8 wearing and tearing length shorten, spring 10 is compensation automatically, guarantees that lead 7 and probe 8 keep in touch state.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment did.
