Description
Technical field
The present invention relates to used for geological prospecting boring tool, be specifically related in single rotary double core barrel the single action mechanism for separating of inner and outer tubes.
Background technology
The current conventional main single tube of core drill or two-tube single action core drill, wherein, two-tube single action drilling tool has avoided drilling tool to rotate and the frictional vibration that the produces Mechanical Crushing to rock core, thereby its quality of coring is high.Single rotary double core barrel comprises outer pipe assembly and the inner tube assembly of socket, outer pipe assembly comprises assemblies such as playing block head, bullet card chamber, reamer, outer tube, drill bit, inner tube assembly comprises the assemblies such as salvaging mechanism, bullet card detent mechanism, hitch, single action mechanism, core catching mechanism, wherein, salvaging mechanism comprises and drags for spearhead, drags for the compositions such as lance seat, recovery tube, spring, for extracting rock core; Bullet card detent mechanism comprises bullet card holder, plays clamp, tension spring etc., and its effect is to be opened inner tube assembly is located by bullet clamp, shrinks by playing clamp simultaneously, realizes in inner tube and carrying, thereby realize, cores; Hitch is comprised of seat ring and hanging ring, and its effect is to guarantee there is certain distance between clip spring seat and drill bit, and after guaranteeing that inner tube assembly puts in place, outer tube single action is flexible; Single action mechanism comprises the upper and lower and axle sleeve on axle, axle, and its effect is that to realize outer tube separated with inner tube, make outer tube single action, and inner tube is motionless; Core catching mechanism comprises jump ring, clip spring seat and inner tube, and while carrying on inner pipe, by the relative motion of jump ring and clip spring seat, card breaks and holds rock core tightly.
Single action mechanism in existing single rotary double core barrel deposits following defect: on the one hand, bearing is longer from tank filler sleeve distance with the axle section of cooperation, and lubrication oil is difficult to arrive axle sleeve and the axle section of cooperation, and when axle rotates in axle sleeve, axle is easily because friction suffers damage; On the other hand, on axle, there is no buffer gear, when axle rotates, easily cause vibration, fragile axle and axle upper bearing (metal); Moreover, because axle is longer, only have pair of bearings to play a supporting role to axle, when running up, radial force is unbalanced, can accelerate the inefficacy of bearing, simultaneous buffering mechanism easily with axle generation frictional interference, cause single action mechanism to scrap.
Summary of the invention
The applicant improves for above-mentioned shortcoming of the prior art, and a kind of modified drilling tool single action mechanism is provided, and when it realizes drilling tool single action, can effectively protect to the axle in single action mechanism, axle sleeve and bearing long service life, stable performance.
Technical scheme of the present invention is as follows:
A kind of modified drilling tool single action mechanism, comprise axle, on the outer peripheral face of axle, be connected with the first joint, bearing support, upper bearing (metal), axle sleeve, lower bearing and locking nut from top to bottom in turn, axle sleeve is assemblied in the second joint, second joint one end is threaded with bearing support, the second joint other end is connected with Internal Pipe Thread, the shaft part of lower bearing and the axle below lower bearing is all positioned at inner tube, in axle vertically with oil transportation channel, oil transportation channel extends to axle sleeve and the axle section of cooperation, and the bottom of oil transportation channel is communicated with by oil outlet with the cylindrical of axle; On shaft part between lower bearing and locking nut, be arranged with spring and packing ring, inner tube is provided with radial direction oil hole, and oilhole is communicated with the inner chamber of inner tube, described intracavity bottom is provided with bearing, locking nut is installed in bearing, between packing ring and locking nut, has gap, and spring is in compressive state.
Technique effect of the present invention:
The present invention is realizing on the basis of drilling tool single action function, oil transportation channel is set in axle, make lubrication oil enter axle sleeve and upper and lower bearing by oil outlet, when axle rotates in axle sleeve, play lubrication, thereby the problem of avoiding axle and axle sleeve to damage, protection axle and axle sleeve have been avoided, at axle cylindrical, the impact of oil groove on axle intensity is set simultaneously; On the other hand; at axle hypomere, be arranged with spring; when axle rotates; spring can play vibration reduction and cushioning effect, avoids because vibration causes damaging the problem of axle and upper and lower bearing protection axle and bearing; in the bottom of interior tube cavity, increasing a bearing supports the end of axle; avoided the unstable infringement that mechanism performance brought of axle when running up, extended its application life, and performance has been more stable.
Accompanying drawing explanation
Fig. 1 is sectional structure schematic diagram of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
See Fig. 1, the present invention includes axle 1, on the outer peripheral face of axle 1, be socketed with successively the first joint 2 from top to bottom, bearing support 3, upper bearing (metal) 4, axle sleeve 5, lower bearing 6 and locking nut 7, axle sleeve 5 is assemblied in the second joint 8, second joint 8 one end are threaded with bearing support 3, second joint 8 other ends are threaded with inner tube 9, the shaft part of lower bearing 6 and the lower bearing axle 1 below 6 is all positioned at inner tube 9, in axle 1 vertically with oil transportation channel 14, oil transportation channel 14 extends to axle sleeve 5 and axle 1 section of cooperation, the bottom of oil transportation channel 14 is communicated with by oil outlet 10 with the cylindrical of axle, on shaft part between lower bearing 6 and locking nut 7, be arranged with spring 11 and packing ring 12, inner tube 9 is provided with radial direction oil hole 13, oilhole 13 is communicated with the inner chamber of inner tube 9, described intracavity bottom is provided with bearing 15, locking nut 7 is installed in bearing 15, between packing ring 12 and locking nut 7, there is gap, spring 11 is in compressive state, 11 pairs of lower bearings 6 of compressed spring play certain supporting role.
After inner tube is transferred and is put in place, start to creep into operation, now, outer tube rotates coring with drilling rod, drill bit, simultaneously under the effect of upper bearing (metal) 4 and lower bearing 6, inner tube 9 is separated with drilling tool outer tube, drilling tool single action, i.e. axle 1 and outer tube rotation, and inner tube 9 is not rotated, the object that inner tube 9 is not rotated is in order to fill coring, and axle 1 rotation is in order not produce relative motion, reduces wear.Lubrication oil enters the section of cooperation and the upper and lower bearing of axle sleeve 5 and axle 1 from oil transportation channel 14 and oil outlet 10, axle 1, when the interior rotation of axle sleeve 5, plays lubrication, thus the problem of avoiding axle 1 and axle sleeve 5 to damage, on the other hand, at axle 1 hypomere, be arranged with spring 11, when axle 1 rotates, spring 11 can play vibration reduction and cushioning effect, avoid causing damaging axle 1 and upper because of vibration, the problem of lower bearing, in addition, locking nut 7 is installed in bearing 15, between packing ring 12 and locking nut 7, there is gap, make axle 1 not can with spring 11 and packing ring 12 interferences, not only make whole axle 1 stressed more balanced, the performance of Ye Shi mechanism is more stable, life-span is longer, spring 11 is in compressive state, 11 pairs of lower bearings 6 of compressed spring play certain supporting role, increased the reliability of whole mechanism.
More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of modification.
