Technical field
The utility model relates to the directed drilling rod of a kind of Integral-type screw groove for directional drilling construction in soft projecting coal bed and broken coal seam under the coal mine.
Technical background
The long drilled holes Technology of Directional Drilling relies on the controlled advantage of its drilling track to be widely used, but because complex geologic conditions, the structure such as yolk coal, broken coal coal is grown, in case the serious drilling accidents such as bit freezing, bury drills occur, will cause huge economic loss.The structure that not only needs to have large through-hole as the directed drilling rod of supporting drilling tool is in order to arrange communication cable, requires simultaneously drilling rod to have very high comprehensive mechanical performance with the compound action power such as adapt to its suffered tensile, compressive, bending, turn round.At present, directed drilling rod mainly contains two kinds of borehole wire-line coring drilling rod and central cables.The wall thickness less of borehole wire-line coring drilling rod, antitorque, bending resistance and the tensile strength of drilling rod are relatively poor, when weak seam or water-swellable stratum construction directional drilling, the accidents such as disconnected bar occur easily; Although central cable has increased wall thickness, this drilling rod is outer flat structure, when running into soft projecting coal bed and broken coal seam, the accidents such as bit freezing occurs easily, has greatly improved the boring cost.
The utility model content
For overcoming the deficiencies in the prior art, the utility model provides a kind of Integral-type screw groove directed drilling rod, can not only be in real time, signal at the bottom of the transmission hole exactly, can effectively process the drilling accidents such as bit freezing, bury drills simultaneously.
The technical solution adopted in the utility model is, the directed drilling rod of a kind of Integral-type screw groove, comprise the logical cable device in drilling rod body and the center that is arranged on axial location in the drilling rod body, the two ends of drilling rod body are respectively equipped with quick union, the external wall of drilling rod is provided with helical groove, and described drilling rod body, helical groove and quick union are monolithic construction.Deviational survey signal transmitting apparatus at the bottom of adopting the logical cable device in center that the technical program, the utility model be arranged on axial location in the drilling rod body as the hole can be in real time, signal at the bottom of the delivery outlet exactly.
The quick union of described two ends of drill setting is respectively male joint and female joint, is provided with external screw thread in the described male joint, is provided with internal thread in the female joint.Internal and external screw thread is used for the rapid abutting joint between two drilling rods, the yield strength＞880MPa of screw thread, torsional strength＞7300Nm.Adopt the technical program, internal and external screw thread is used for the rapid abutting joint between two drilling rods, and screw thread has certain bending resistance, antitorque and tensile strength.
Described helical groove and internal and external screw thread all are directly to process on the drilling rod body.As preferably, the monolithic construction of described drilling rod body has improved antitorque, bending resistance and the tensile strength of drilling rod; In addition, helical groove and internal and external screw thread all are directly to process on the drilling rod body, are of value to the manufacturing procedure that reduces drilling rod, enhance productivity, and reduce production costs.
The quantity of described helical groove is at least 1.Adopt the technical program, be provided with on the outer wall of the utility model drilling rod body and be no less than one helical groove, need to rotate the pulling drilling rod in abnormal conditions such as bit freezing, bury drills occur, the seamed edge of helical groove can blend the coal cinder of bit freezing, helical groove has the effect of auxiliary row's powder simultaneously, can efficient solution bit freezing bar.
The cross section of described helical groove is circular arc or square or rectangle or trapezoidal.As better, the cross section of described helical groove is circular arc or square, can according to what of coal dust discharge rate in the actual working environment, select cross sectional shape and the degree of depth of suitable helical groove.
The utility model is with respect to prior art, and its advantage is: antitorque, the bending resistance and the tensile strength that have improved drilling rod; Enhance productivity, reduce production costs; Drilling rod not only can be in real time, signal at the bottom of the transmission hole exactly, can effectively process the drilling accidents such as bit freezing, bury drills simultaneously, reduced the boring cost.
