Specific embodiment
It is next below with reference to the accompanying drawings that the present invention will be described in detail.It should be noted that in the absence of conflict, in the application
Embodiment and embodiment in feature can be combined with each other.
Referring to Fig. 1 to Fig. 4.
The present invention abolishes the device of boulder bit freezing, including sleeve drill bit 1 and drilling rod 2；
The sleeve drill bit 1 includes sleeve drill bit cylinder 11 and the axial one end for being fixed on the sleeve drill bit cylinder 11
The axial other end of more than one cutter 12, the sleeve drill bit cylinder 11 is connect with axial one end of the drilling rod 2.
In use, rotated by drilling rod band moving sleeve drill bit cylinder, it, will be by card centered on the drilling rod being had by bit freezing
The original drilling of drilling tool slightly expands, and boulder 3 can be cut by expanding to bit freezing boulder position, while circulation mud, will break
The boring mud of the stone and precipitating that remove cleans out drilling, achievees the purpose that release boulder bit freezing and sediment burying restraining force, most drop back
Device out will be had by bit freezing and salvage.
Preferably, the internal diameter of the sleeve drill bit cylinder 11 is greater than the outer diameter being had by bit freezing.It designs in this way, it can by bit freezing tool
To protrude into sleeve drill bit cylinder, in use, sleeve drill bit can will be had by bit freezing and be completely nested in it, such as Fig. 2 to reaming
It is shown, to farthest release sediment burying restraining force, had convenient for subsequent salvaging by bit freezing.
In specific implementation, cutter uses alloy scraper, and effect is more preferable.
In one embodiment, the drilling rod 2 include guide rod 21, the guide rod 21 be equipped with axially through guiding
The axial other end in hole, the sleeve drill bit cylinder 11 is connect with axial one end of the guide rod 21, the drilling rod being had by bit freezing
It can protrude into the pilot hole.The guide rod of setting plays guiding role to sleeve drill bit, in use, the drilling rod being had by bit freezing is first
The inner cavity of sleeve drill bit cylinder is protruded into, is then protruded into the pilot hole on guide rod, so that sleeve drill bit be made to have along by bit freezing
Drilling track toward reaming, it is ensured that the new counterboring hole of device and former drilling are concentric, prevent two hole decentractions from leading to sleeve drill bit
Head, which is got into, has guiding disk by bit freezing, can not continue be had by bit freezing downwards and be inserted in it, guarantee to release boulder bit freezing and sediment
The effect of burying restraining force.
Preferably, the guide rod 21 includes outer barrel 211 and is spaced the inner cylinder being set in the outer barrel 211 in the same direction
Body 212, and the axial ends of the outer barrel 211 exceeds the axial ends of the inner cylinder 212, the outer barrel outward respectively
Between 211 axial one end and axial one end of the inner cylinder 212 and the axial other end of the outer barrel 211 with it is described
Multiple centrum panels 213 for being spaced apart from each other distribution are connected separately between the axial other end of inner cylinder 212.It designs in this way, it is interior
The inner cavity of cylinder is the pilot hole；Outer barrel can reinforce the intensity of guide rod, convenient for ring flange is arranged with easy at both ends
It is connect in other components；Centrum panel, playing connection outer barrel and inner cylinder can guide with certain taper
Entered in inner cylinder by the drilling rod that bit freezing has, because needing circulating mud to clear up boring mud when set bores, the gap between each centrum panel can
To increase mud cross-sectional flow area in guide rod, fluid resistance is reduced.
Preferably, the centrum panel 213 is in a strip shape.Effect is relatively reliable.
Preferably, each centrum panel 213 is uniformly distributed along the circumferential direction of guide rod.Structure is more reasonable, and stress is more
Uniformly.
Preferably, the angle between the centrum panel 213 and the outer barrel 211 is 25 degree.Angle is smaller, by bit freezing
Resistance when tool drilling rod enters in guide rod is with regard to smaller, and using this angle, not only resistance is small, but also structure is also more stable.
In one embodiment, the inner surface and the inner cylinder at the back side of the centrum panel 213 and the outer barrel 211
Centrum vertical plate 214 is connected between 212 outer surface.Centrum vertical plate plays the role of reinforcing this three connection, improves device knot
Structure strength and stability.Preferably, for centrum vertical plate perpendicular to centrum panel and inside and outside cylinder, reinforcing effect is more preferable.
In one embodiment, the axial ends of the outer barrel 211 is respectively equipped with ring flange 215.It is convenient that ring flange is set
It is connect with other components such as sleeve drill bit cylinders.
In one embodiment, reinforcement is connected between the back side of the ring flange 215 and the outer surface of the outer barrel 211
Gusset 216.Stiffener plate is set to further increase structural strength.In one embodiment, the drilling rod 2 further includes hollow stem
22, the axial other end of the outer barrel 211 is connect with axial one end of the hollow stem 22.Hollow stem plays the work of resigning
With the drilling rod for being had by bit freezing protrudes into, and cooperating has being had by bit freezing for more long drill pipe.
In one embodiment, the hollow stem 22 is divided into two sections being successively detachably connected or more.It can according to need
Dismounting and selection joint number, practicability are more preferable.
In one embodiment, the tapered design of the axial other end of the sleeve drill bit cylinder 11.In this way design, convenient for
Drilling rod transition connection, and the drilling rod being had by bit freezing can be guided to enter pilot hole.
It should be understood that example as described herein and embodiment are not intended to restrict the invention, this field only for explanation
Technical staff can make various modifications or variation according to it, all within the spirits and principles of the present invention, made any modification,
Equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
