Abstract
The utility model provides a concealed signal communication cable of a directional drilling machine for underground gas drilling and water surveying in a coal mine. The concealed signal communication cable is characterized in that, the conventional 333 communication cables are replaced by 16 communication cables, a concealed signal communication cable fixing frame is concealed inside a drill stem with a plug sealed, the sealed cables are concealed in a pipe body of the drill stem by a fixing plug, the concealed signal communication cable is winded on the concealed signal communication cable fixing frame with one end inserted into a hole bottom drill pipe socket while a highly sealed plug at the other end is concealed in the concealed signal communication cable, and the winded signal communication cable fixing frame with the signal communication cable is mounted in the drill stem. The concealed signal communication cable is advantageous in that, the measuring capability and accuracy are improved, and the measuring precision is improved; the drilling speed is obviously increased; the number of plug joints is reduced, so that poor contacts which are caused by the high humidity underground and the oxidation and corrosion of the plugs and influences the signal transmission are prevented; and the directional drilling efficiency of the directional drilling machine is significantly improved, and the precision of drilling trajectory is obviously improved.
Description
Technical field
The present invention relates to the exploration of a kind of pit of coal draws out methane and visits the measuring built-in signal of the directional drilling machine that discharges water, particularly a kind of directional drilling machine and lead to cable.
Background technology
The logical cable of built-in signal is that the directional drilling measurement-while-drilling system is brought into play the indispensable part of its effect, existing directional drilling machine measuring-signal is to be 3 meter one joint with the interior conducting cable of drilling rod, mutually peg graft, must 333 joints if make a call to the deep hole of a km, the chance of leaking like this is a lot, often too many because of joint in executing the brill process, the sealing of existing joint is to seal with sealing ring, because be to utilize water under high pressure as operation power in the drilling rod, the water under high pressure of 7Mpa is arranged in the drilling rod, often turn round when holing because of drilling rod again, bending force is larger, therefore often having drainage, drilling rod in a single day to leak wire will short circuit, and measurement will be failed.So just must pull out drilling rod from the hole, check leakage point, then replace this joint drilling rod, brill is executed in the effort of so repeatedly taking a lot of work impact.In drilling process, because drilling rod is constantly crooked, easier leaking in case signal short circuit 300 multiple-contacts do not know which contact leaks, searched the difficulty impact and executed and bore the effort of taking a lot of work.
Summary of the invention
The purpose of this utility model is the deficiency that exists in the above-mentioned technology, provides a kind of built-in signal to lead to cable.Adopt built-in signal to lead to the special grafting of cable, improve bonding strength and sealing.60 rice grain pattern cables can be hidden in the drilling rod, make the signal can not short circuit, measuring-signal be smooth and easy, accurately, has improved the accuracy rate of measuring.
The purpose of this utility model is achieved in that and comprises a logical cable of built-in signal with 60 meters long, the logical cable of built-in signal is hidden coil holder, the high sealing plug, the limit line length is inserted axle, the drilling rod spacing ring, built-in signal leads to cable linking springs, inserting tube socket at the bottom of the connecting hole, inserting tube plug, and drilling rod.It is characterized in that, change 16 logical cables into by existing 333 logical cables, the logical cable fixed mount of built-in signal is hidden in drilling rod inside, the plug sealing, and conduction property is good.The cable of good seal is hidden in the drill pipe body with locking-type plug.The logical cable of built-in signal is wrapped on the logical cable frame of built-in signal, and on the inserting tube socket, other end high sealing plug is hidden in the logical cable of built-in signal at the bottom of the end patchhole, then the logical cable frame of signal that winds is packed in the drilling rod together with the logical cable of signal.The logical cable socket of signal is installed in the probe front end at the bottom of the hole, and spacing ring is installed in the cable rack front end.Cable seal adopted double containment grafting sealing when holding wire connected.Use insulating material and encapsulating method.
The beneficial effects of the utility model are, utilize built-in signal to lead to the cable frame, are hidden in the drilling rod, reduce joint and avoid leaking, and the deviational survey system is installed at the bottom of the hole, reach with the purpose of boring deviational survey by the transmission of the logical cable of built-in signal to signal.Real realization can both to measure at the bottom of the hole, improve and measure accuracy rate at any time.The logical cable of built-in signal is hidden in the drilling rod cleverly, because the logical cable of built-in signal is long, it is smooth and easy to communicate by letter, and has improved measurement capability and accuracy.Original signal transmission grafting point is many, 333 joints are arranged, the more resistance of joint are larger, affect the signal transmission, this invention is owing to prolonged the logical cable length of built-in signal, and it is smooth and easy that the minimizing joint also just reduces resistance signal, and process the logical cable of nonstandard built-in signal and hide coil holder, so that signal measurement is convenient, accurately, improved certainty of measurement.Because the logical cable of built-in signal is long, the dress once logical cable of built-in signal can once creep into 20 drilling rods, has reduced unnecessary wait and non-cutting time, so that rate of penetration obviously improves.Because be 60 meters one the logical cable of signal, the signal transmission precision is high.The logical cable of built-in signal is long, has reduced the point of pegging graft and has avoided owing to the down-hole high humidity, and the plug oxidation corrosion causes loose contact to affect the signal transmission.Adopt the logical cable of built-in signal to overcome the shortcoming and defect of above-mentioned 3 meters one logical cable drilling rod, the directional drilling efficient of directional drilling machine is improved greatly, on the precision of drilling trace also by obvious improvement.To improving Safety of Coal Mine Production efficient important meaning is arranged.Adopt and use targetedly special material, make measuring-signal convenient, greatly improve and measure accuracy rate.
