Description
Affiliated technical field
The present invention relates to the anti-reaming bit that circulates of drive-type horizontal directional drill in a kind of hole, this drill bit is used to adopt horizontal orientation to creep into technology to carry out oil gas or municipal pipeline laying construction, belong to the trenchless engineering technical field.
Background technology
At present, adopting horizontal orientation to creep in the construction of technology tubing, increasing along with duct length and bore diameter, the engineering difficulty is also increasing.Particularly pass through engineering for large-scale horizontal directional drill, needed construction equipment is also huge especially, and the moment of torsion of rig often will reach more than 10 Wan Niumi, and the pull-back force of rig will reach more than 300 tons, and maximum now rig pull-back force has reached 800 tons.In addition, along with the increase in aperture, position and the state of drilling rod in horizontal drilling is difficult to control, adds the drilling rod revolution to the friction of hole wall and the wearing and tearing of drilling rod self, and drilling rod drilling accident odds such as fracture is very high.So large-scale horizontal directional drill engineering manufactures and designs horizontal directional drill rig and facility and has all proposed very high requirement.Existingly also there is following shortcoming by the technology that drilling rod revolution drives the reaming bit rock cutting by face of land rig:
1) drilling rod when revolution and hole wall friction, not only drilling rod there are wearing and tearing, application life of shortening drilling rod, and drilling rod turns round, and is under the most evil bad working condition, take place easily that drilling rod fractures and fatigue failure in the boring of bending.
2) the drilling rod rotation is bigger to the wall stability influence, and borehole shape is changed.
3) face of land power is bigger by the process loss that drilling rod is delivered to reaming bit by rig.
4) more at the inner hole deposition slag, when sandy soil content is big in the mud, easily cause drilling tool serious wear, reaming moment of torsion excessive, engineering accidents such as bit freezing and drilling tool fracture appear.
Summary of the invention
In order to overcome the defective that exists in the prior art, the invention provides the anti-reaming bit that circulates of drive-type horizontal directional drill in a kind of hole, can overcome tabledriven above-mentionedly series of malpractice.
The technical solution adopted for the present invention to solve the technical problems is: the anti-reaming bit that circulates of drive-type horizontal directional drill in a kind of hole, this drill bit comprises bit body and Power Drive Unit at least, the drill bit cone of bit body and the inside of lip pencil conehead are the cavity of hollow, power transmission shaft middle part in the Power Drive Unit is provided with rotating disk, the gear wheel seat that gear wheel is housed is installed on the rotating disk, the tail end of drill bit cone is installed on the rearward end of power transmission shaft by bearing, the tail end of lip pencil conehead is installed on the leading section of power transmission shaft by bearing, and the motor in the Power Drive Unit drives rotating disk and gear wheel rotates through power transmission shaft; Motor is positioned at the cavity of drill bit cone, and tool joint is plugged in the cavity of lip pencil conehead, and perhaps motor is positioned at the cavity of lip pencil conehead, and tool joint is plugged in the cavity of drill bit cone; The inside of tool joint is hollow cavity, and the cavity of tool joint is by the cavity of lip pencil conehead or the cavity of drill bit cone, and some slag suction mouths and external communications, and slag suction mouth is positioned at the gear wheel side-lower.
The present invention creeps into horizontal orientation in the technology and drives the rotating power of reaming bit and change the self-driven mode of reaming bit at the bottom of the hole into by traditional face of land rig drive-type as shown from the above technical solution, to overcome tabledriven above-mentionedly various drawbacks.And the power reaming bit is discharged the rock slag with anti-endless form at the bottom of this hole, can also overcome traditional direct circulation major diameter horizontal orientation and creep into the extremely difficult a series of technical barriers of deslagging that method exists, and can reduce engineering cost significantly.
Therefore, the present invention compared with prior art has following beneficial effect:
1) adopts anti-circulation reaming to creep into, can remove boring mud or ovum gravel in the boring efficiently, do not stay the dead angle.Therefore can reduce the hole enlargement coefficient of boring effectively, thereby reduce reaming sum of series hole flushing number of times.
2) power set are directly installed on the drill bit in the hole, and drilling rod must not rotate in the drilling process, overcomes the rotating whole shortcomings of drilling rod;
3) can reduce the wearing and tearing of drilling rod greatly, prolong the application life of drilling rod;
4) can avoid because of the destruction of drilling rod rotary vibration, reduce the generation of drilling accident borehole wall;
5) not friction between drilling rod and the hole wall helps reducing power consumption, improves capacity usage ratio;
6) the power drive reaming bit turns round under the hole, has improved the force-bearing situation of drilling rod, has reduced the requirement to the drilling rod material;
7) can reduce horizontal directional drilling machine requirement to this key parameter of rig moment of torsion in design and use greatly.
