[detailed description of the invention]
In example shown in the drawings, as shown in Figure 1 and Figure 2, a kind of bore expanded hole integrated apparatus, it is characterised in that it includes driving axle, the first reaming ring body, the second reaming ring body, rifler, reaming tooth, reaming teeth groove, keyway, depositing bits groove；Described rifler is single-cone rotary drill bit, tricone bit, and the inside level in center, left side of rifler offers cylindrical groove；Described driving axle is cylindrical, drives the right-hand end of axle to embed in the cylinder shape groove of rifler left side, and the top of rifler center vertical cross-section is each with bottom edge place inwardly vertically offer together with rectangular keyway, keyway deeply drives in axle；nullDescribed first reaming ring body and the second reaming ring body are all in circular platform type，And equal level in centre offers cylindrical through hole in it，First reaming ring body and the second reaming ring body are all overlapped on the driving shaft by through hole，The roundlet end face of the second reaming ring body and rifler are close to，The roundlet end face circle external diameter of the second reaming ring body is equal with the end face circle external diameter being close to rifler，The roundlet end face of the first reaming ring body and the large round end surface of the second reaming ring body are close to，The roundlet end face circle external diameter of the first reaming ring body and the large round end surface circle external diameter of the second reaming ring body are equal，The tip edge center of the first reaming ring body and the second reaming ring body center vertical cross-section and bottom edge center all vertically inwardly horizontal symmetry offer together with rectangular keyway，Keyway all deeply drives in axle，The tip edge of the first reaming ring body and the second reaming ring body center vertical cross-section and bottom edge be each symmetrical reaming teeth groove being provided with two cylindrical form near keyway place，The front edge in the first reaming ring body and the second reaming ring body central horizontal cross section and back edge center are also respectively provided with the reaming teeth groove of a cylindrical form，Each reaming teeth groove is all embedded with the reaming tooth in T font，Reaming tooth tip is equipped with the blade for cutting rock，The tip edge in the first reaming ring body and the second reaming ring body center vertical cross section and bottom edge place be all respectively provided with one rectangular and be inwardly recessed deposit bits groove；Described reaming teeth groove is all embedded with reaming tooth is fixed on the key in reaming teeth groove, keyway is also equipped with for fixing key.
nullThe present invention has the function of boring and reaming simultaneously，Before reaming, operating personnel need to first determine the diameter of institute's reaming，When expanding small size pores，Make the large round end surface circle external diameter of the second reaming ring body that processing and fabricating goes out and the equal diameters of required reaming，And the second reaming ring body is overlapped on the driving shaft，And key is positioned in keyway the second reaming ring body is fixed with driving axle，First reaming ring body need not overlap on the driving shaft，So when driving axle to rotate propelling，The rifler driving axle front end can first be holed，Until the first reaming ring body enters the hole that rifler bores，And then the reaming tooth being embedded in the second reaming ring body reaming teeth groove can rotate，And cut rock by the blade of reaming tooth tip and complete reaming，What the first reaming ring body and the second reaming ring body were provided with deposit, and bits groove can deposit the carg cut down by blade temporarily，Carg is avoided to pile up between reaming tooth and the rotation of bore expanded hole device is caused resistance，It is also beneficial to heat radiation，In addition people can also according to the needs of actual situations of construction，The reaming tooth of embedded different-stiffness in reaming teeth groove，To adapt to the needs of varying strength rock reaming.When needs expand pore, the large round end surface circle external diameter of the first reaming ring body that processing and fabricating goes out and the equal diameters of required reaming can be made, and the first reaming ring body is overlapped on the driving shaft, the large round end surface making the first reaming ring body roundlet end face and the second reaming ring body is close to, and key is positioned in keyway the first reaming ring body is fixed with driving axle, same under the rotarily driving driving axle, reaming tooth in first reaming ring body reaming teeth groove can rotate, and cut rock by the blade of reaming tooth tip and complete reaming, when hole and the reaming boring of expanding different pore size, different equipment need not be changed carry out, thus the present invention has the function of boring and reaming simultaneously, and the hole of different-diameter can be expanded, improve reaming efficiency, reduce construction cost, also save construction period.
