Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.It should be noted that at this, the explanation for these embodiments understands the utility model for helping, but does not form restriction of the present utility model.
As shown in Figures 1 to 8, the utility model comprises drill bit 1, drilling rod 2 and deflection preventer 3, described deflection preventer 3 is in the annulus bodily form, described deflection preventer 3 is set in described drilling rod 2 periphery and is removably connected with described drilling rod 2, described deflection preventer 3 comprises deflection preventer body 31 and auxiliary bore hole mechanism 32, described deflection preventer body 31 outer wall has rhone 33, described auxiliary bore hole mechanism 32 is fixed on the end face of described deflection preventer body 31, and the cutting diameter of described auxiliary bore hole mechanism 32 is identical with described deflection preventer body 31 external diameter.When drill bit 1 creeps into, deflection preventer 3 together rotates thereupon, and deflection preventer 3 can play the effect of righting drill bit 1, prevents drill bit 1 side from offseting downward because Action of Gravity Field produces.Drill bit 1 rocks owing to can produce in drilling process, cause bored hole irregular, and then cause deflection preventer 3 cannot enter hole smoothly, can address this problem in the auxiliary bore hole mechanism 32 of deflection preventer body 31 end face, its principle is: auxiliary bore hole mechanism 32 together rotates along with creeping into of drill bit 1, the auxiliary bore hole mechanism 32 of High Rotation Speed can carry out cutting finishing to hole wall, is equivalent to bore hole, reduces resistance suffered when deflection preventer 3 enters.Auxiliary bore hole mechanism 32 also has effect on the other hand, namely increases the intensity of deflection preventer 3.Drill bit 1 can produce slag and water in the process of creeping into, and the foreign material such as slag and water can be discharged by the rhone 33 being positioned at deflection preventer body 31 outer wall.
Specifically, deflection preventer 3 can adopt latch fixed form and screw fixation method etc. with the fixed form of drilling rod 2.Preferably, as shown in Figure 2, adopt screw fixation method, detailed description of the invention is: on the sidewall of deflection preventer body 31, open multiple screwed hole 34, adopt the screw mated with screwed hole 34 to screw in screwed hole 34, tighten screw and just deflection preventer 3 can be fixed on drilling rod 2.After preventing screw-driving, there is exposed parts, screwed hole 34 can be designed to screw-threaded counterbore, like this, the ledge be exposed at outside deflection preventer body 31 outer wall after tightening screw, would not be had.The quantity of screw can be selected as required, and as depicted in figs. 1 and 2, each deflection preventer 3 can adopt a pair or two pairs of screws are fixed.
Specifically, pass in and out hole to further facilitate deflection preventer 3, external diameter 1 to the 2mm less of the diameter of described drill bit 1 of described deflection preventer body 31.In the process that drill bit 1 creeps into, along with bored hole is more and more darker, the part that drilling rod 2 enters hole is more and more longer, and drilling rod 2 will produce bending, and drill bit 1 and deflection preventer 3 all can offset downward, secondly rising because rock is swollen or loses pressure hole wall can be uneven, therefore, the external diameter of deflection preventer body 31 is designed less than the diameter of drill bit 1, can reduce or avoid on the downside of deflection preventer 3 with hole wall friction, facilitate deflection preventer 3 to pass in and out hole, the application life of deflection preventer 3 can also be extended.
Specifically, as shown in Figures 1 to 5, described auxiliary bore hole mechanism 32 is multiple leg-of-mutton block structures, and described multiple block structure is uniformly distributed along the circumference of described deflection preventer body 31 on the end face of described deflection preventer body 31, each gore is welded on the end face of deflection preventer body 31, and its protruded length is no more than 2mm.Preferably, the number of triangle block structure is 4.Certainly, auxiliary bore hole mechanism 32 can also adopt other structures, column structure as shown in Figure 6 and Figure 7, rectangle block structure etc.
Specifically, as shown in Figures 2 and 3, described auxiliary bore hole mechanism 32 is fixed on an end face of described deflection preventer body 31.In order to make deflection preventer 3 can pass in and out hole smoothly, need to adopt two or more deflection preventers 3.Preferably, the number of described deflection preventer 3 is two.Wherein from the auxiliary bore hole mechanism 32 of that deflection preventer 3 close to described drill bit 1 towards described drill bit 1, wherein from the auxiliary bore hole mechanism 32 described drill bit 1 dorsad of that deflection preventer 3 away from described drill bit 1.When inlet hole, hole wall can be repaired by the mechanism of auxiliary bore hole mechanism 32 on the deflection preventer 3 that drill bit 1 enters, and facilitates deflection preventer 3 to enter; Sometimes, there will be the situation across hole when moving back hole, now, can hole wall be repaired from the auxiliary bore hole mechanism 32 on the deflection preventer 3 away from drill bit 1, facilitating deflection preventer 3 and drill bit 1 to portal.
Specifically, as shown in Figure 8, two end faces of described deflection preventer body 31 are all fixed with auxiliary bore hole mechanism 32.Adopt this structure convenient, the finishing to hole wall when only using a deflection preventer 3 just can realize inlet hole and portal.
Specifically, the discharge of the foreign material such as the slag conveniently produced during boring and water, as shown in Figure 2, described rhone 33 is along described deflection preventer body 31 outer wall spiral surrounding.In the process of High Rotation Speed, water and slag will be subject to a revolving force, under the effect of this power, water and slag no longer do rectilinear motion, rhone 33 is designed to spirality, the shape of rhone 33 can be made to mate with the movement locus of foreign material, conveniently foreign material are discharged.Concrete, the width of rhone 33 is 8 to 12mm, and the degree of depth is 3 to 7mm, and number is 3 to 5.
Preferably, adopt diameter to be the drill bit 1 of 75m and diameter to be the drilling rod 2 of 42mm, the length of the deflection preventer 3 matched is 200mm, external diameter is 73mm, internal diameter is 44mm, and the width of the rhone 33 on deflection preventer body 31 outer wall is 10mm, and the degree of depth is 5mm, length is 207mm, and the number of rhone 33 is preferably 4.
Specifically, in order to make the longer service life of deflection preventer 3, the material of described auxiliary bore hole mechanism 32 is alloy steel.The hardness of alloy steel is comparatively large, impaired less in the process of cutting hole wall, longer service life.
Concrete, the anti-bias effect of drilling anti-deflection device can be controlled by the position and quantity adjusting deflection preventer 3, boring can be constructed by the angle of design position, hole and orientation.In drilling process, can effective supports drill rods at the described deflection preventer body 31 that distributes in pairs of design hole depth half place, reach anti-bias object of holing.
