Description
Technical field
The utility model relates to a kind of horizontal directional drill power reaming helicoid hydraulic motor, belongs to non-excavation petroleum drilling and mining technical field.
Background technology
Traditional non-excavation horizontal directional drill construction adopts the boring drill that is installed on earth's surface, by unit head, directly drive drilling rod to drive reamer and carry out ream operation, pierce stratum with the penetrating angle less with respect to ground, form pilot hole, then by the pilot hole hole enlargement to required big or small pipeline, return and be dragged in hole along the pilot hole enlarged, complete the Pipeline Crossing Program construction.The drilling rod of reamer towing is longer, and flexibility is larger, consumes energy high, and efficiency is low, and broken rock is short of power, and often occurs that reamer is suppressed, blocks, jumps, blocked up, eccentric wear, gets rid of the accidents such as brill, breaking of rod bar and reamer damage, affects the construction period progress.Accident rate in long distance, heavy caliber (counter bore diameter φ >=1016mm, reaming are apart from more than 2000m) and the construction of complicated geological directional traversing is high, efficiency is low and First Pass Yield is low, in multistage reaming process in the case, need to repeatedly pull reamer, above unload drilling rod.Affected by geological conditions rock parameter variation etc., drilling rod and reamer stressed complicated and changeable, load variations is unexpected, and drill pipe wobbling is violent, causes the reaming difficulty, returns and drag resistance increment, reaming track and guide track departs from and unfreezing.
The key technology of horizontal directional drill construction is according to different soil layers and pore-forming requirement, and selecting properly returns formula and the consumption of expanding drilling tool and mud.But, the brill that existing various helicoid hydraulic motor all is unsuitable for heavy caliber, long distance and changeable geology expands demand, reaming efficiency is low, security incident is many, and the MTR of maximum specification also is not enough to bear the power needs that large diameter pipeline passes through reaming, be difficult to meet the needs such as the moment of torsion of horizontal directional drill power reaming and tension.
Summary of the invention
The purpose of this utility model is to provide a kind of horizontal directional drill power reaming helicoid hydraulic motor, and to solve the existing many technical problems of traditional drilling tool, the brill that meets heavy caliber, long distance and changeable geology expands demand.
Concrete technology contents of the present utility model is as follows:
The drive shaft sleeve side face of this drilling tool evenly is provided with the mud hole, the sleeve lining front end power transmission shaft that is threaded, and rear inner wall is provided with sealing ring and by shoulder connection for transmission beam barrel body; Be provided with the driving-shaft assembly of its front end face of snapping in the power transmission shaft cylindrical shell, power transmission shaft cylinder back-end cone male screw connects the universal drive shaft cylindrical shell; Universal drive shaft cylinder back-end cone male screw connecting screw rod motor assembly, the screw motor assembly rear end taper hole motor joint that is threaded; The power transmission shaft rear end universal drive shaft assembly that is threaded, universal drive shaft assembly rear end cone male screw connecting motor rotor, motor rotor rear end thread connection anti-loose nut.
This drilling tool output torque is large, swings littlely, and overload capacity is strong, and reaming efficiency is high, and reaming sum of series number of times is few, returns to drag with the unfreezing resistance to tension by force, and anti-lost performance is good, simple in structure, safe and reliable, failure rate is low, short construction period.
The accompanying drawing explanation
Fig. 1 is horizontal directional drill power reaming spiral drilling rig structure schematic diagram.
