Abstract

A novel drilling machine without drilling rod relates to a novel diving drilling machine. The novel drilling machine without drilling rod realizes double rotation and double-drill-bit drilling and eliminates the drilling rod. The basic structure of the novel drilling machine is characterized in that: a power output end of a diving motor is provided with an assembling reduction box; a power output end of the reduction box is provided with a transfer case; two power output parts of the transfer case are provided, namely a frontward power output shaft and a backward power output shaft; the end of the frontward power output shaft is provided with a small-diameter frontward rotating drill bit, and the end of the backward power output shaft is provided with a large-diameter backward rotating drill bit; the tail part of the diving motor is provided with a guide rod; the tail part of the guide rod is symmetrically provided with guiding vanes and a wire rope suspender; the guiding vanes are symmetrically equipped outside the body; and one side of the body is provided with a water flushing guide pipe. Because the drilling rod is eliminated, the drilling machine without the drilling rod has strong mobility and facilitates transportation. Simultaneously, because the weight is constant, the load of the lifter is reduced, thereby facilitating automatic control. Furthermore, operation efficiency of the drilling machine is improved without frequent drilling rod change.

Description

Novel no drilling rod rig

Affiliated technical field

The utility model is the advanced diving drill machine of a kind of ten minutes, and this rig is a kind of novel two-way circling round, two drill bit driving rigs; Can realize not having drilling rod automation driving, the strong automaticity of controllability is high.

Background technology

Nowadays the Clothoid type rig that uses is nothing more than two kinds: a kind of is the ratary disk type rig, and power set drive following drill bit driving through driving circling round of drilling rod on the ground.Another kind is common diving drill machine, and its power section is underground, drives the drill bit driving that circles round through submersible motor, and its drilling rod does not change.These two kinds of following problems of rig ubiquity: one is all heavy drilling rod to be arranged, and is not easy to very much transportation, moreover accident often occurs in its replacing process; Another is exactly that unidirectional circling round is easy to generate huge moment of torsion, thereby sprains drilling rod or drill bit; In addition, owing to the increase of drilling rod quantity, its weight is increasing during operation, thereby increases the load of elevator.

Summary of the invention

To the deficiency of present Clothoid type rig, we are ad hoc to have counted this novel no drilling rod rig, and this utility model has realized two circling round, and two drill bits have assembled guide peg, have cancelled drilling rod; Its automaticity is high.

The technical scheme that the utility model solves its technical problem is: novel no drilling rod rig is on the basis of existing diving drill machine, and its diving driving part has been carried out substantial improvement design, has installed transfer case and guide vane additional, guide peg; Realize that two drill bit is two-way circles round, constant weight automation driving, this utility model comprises three parts, is respectively power section, driving part and targeting part.Power section comprises submersible motor, reduction box, transfer case; Driving part comprises forward the circle round drill bit and the drill bit that oppositely circles round; Targeting part comprises guide vane and guide peg.Its basic structure is: at the clutch end assembling reduction box of submersible motor, and the clutch end assembling transfer case of reduction box, the power output of transfer case has two, is respectively positive power output shaft and reverse power output shaft; The little forward of the positive power output shaft terminal assembling diameter drill bit that circles round, the big drill bit that oppositely circles round of reverse power output shaft terminal assembling diameter; The afterbody assembling guide peg of submersible motor, guide peg afterbody symmetry assembling guide vane and wire rope suspender, symmetry assembling guide vane in the body outside; Body one side water is towards conduit.

Its operating principle is: when submersible motor moves; Power conversion through reduction box and transfer case; Circle round drill bit and the drill bit that oppositely circles round of forward rotated simultaneously, and because of the forward bit diameter that circles round is little, the bit diameter that oppositely circles round is big; So can produce two moments of torsion of both forward and reverse directions in the tunneling process, so cancel out each other because of direction is different; Even if because the difference of resistance produces little difference in torque, whole machine body is rotated, because the guide vane on body and the guide peg has played effect, the sharp sword on the guide vane embeds in the earth, can only move up and down, and horizontal resistance is huge; Thereby guarantee that animal economy does not twist, dig the purpose that reaches steady speedy drivage through revolving alternately of positive and negative two drill bits.Body links to each other with ground elevator with wire rope through the wire rope suspender on the guide peg, reaches up and down purpose freely; Water links to each other with ground high pressure slurry pump through high-pressure hose towards conduit, reaches the purpose of the auxiliary driving of circulating mud.

The beneficial effect of the utility model is: 1 has cancelled drilling rod, and convenient transportation has improved mobility.2 these weights of equipment are constant, are convenient to automation control, reduced the elevator load.3 without the frequent change drilling rod, has improved operating efficiency.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further specified

Accompanying drawing is the structure schematic diagram of the utility model.

Among the figure: 1 wire rope suspender, 2 guide vanes, 3 guide pegs, 4 submersible motors, 5 reduction boxes, 6 transfer cases 7 drill bit 8 forwards that oppositely circle round circle round drill bit 9 reverse power output shafts 10 positive power output shafts 11 water towards conduit

The specific embodiment

During submersible motor (4) operation; Power conversion through reduction box (5) and transfer case (6); Circle round drill bit (8) and the drill bit (7) that oppositely circles round of forward rotated simultaneously, and because of forward drill bit (8) diameter that circles round is little, drill bit (7) diameter that oppositely circles round is big; So can produce two moments of torsion of both forward and reverse directions in the tunneling process, so cancel out each other because of direction is different; Even if because the difference of resistance produces little difference in torque, whole machine body is rotated, because the guide vane (2) on body and the guide peg (3) has played effect, the sharp sword on the guide vane (2) embeds in the earth, can only move up and down, and horizontal resistance is huge; Thereby guarantee that animal economy does not twist, dig the purpose that reaches steady speedy drivage through revolving alternately of positive and negative two drill bits.Body links to each other with ground elevator with wire rope through the wire rope suspender (1) on the guide peg (3), reaches up and down purpose freely; Water links to each other with ground high pressure slurry pump through high-pressure hose towards conduit (11), reaches the purpose of the auxiliary driving of circulating mud.
