Abstract
The utility model relates to a rock hole-enlarger of a spire centralizer, comprising a shaft and a barrel body, which is characterized in that: the shaft is arranged on the central axis of the barrel body; a transition-cone is positioned on the front of the barrel body; more than two cutting roller cone holding frames are fixedly arranged on the external circumference of the barrel body along the direction of the circumference, and each of the cutting roller cone holding frame is provided with a cutting roller cone; the spiral centralizer is arranged on the external circumference of the barrel body positioned in front of the cutting roller cone holding frame, and the spiral centralizer is composed of more than two spiral plates. The spiral plates are distributed evenly along the circumferential direction and fixedly connected with the barrel body, and an alloy block which is resistant to abrasion is embedded on the cutting roller cone. The cutting roller cone and the spiral centralizer are arranged in the rock hole-enlarger. The utility model has the advantages of enabling to reduce the impact to the drill and the drilling tool, and prolonging the service life by using the cutting roller cone to grind the rock and enlarge the hole, having slag discharge function of the spiral centralizer, and preventing jamming of drill tool.
Description
Technical field:
The utility model relates to mechanical field, relates in particular to rig, particularly a kind of rock reamer with the spiral centralizer.
Background technology:
Can't excavate in a conventional manner, advance and the operating personnel can't enter under the engineering specifications of workspace, must adopt mechanical means to operate and bore pick, casting, scarfing cinder and direction control, and after reaming, imbed various tubing underground simultaneously, this non-excavating construction method is used widely in municipal engineering, and the equipment that the non-excavating construction method adopts is rig.But when utilizing reamer of the prior art to carry out reaming, need rig all to be applied to whole moments of torsion on the reamer, dependence is embedded in the cutting tooth rock cutting on the tapered reamer, the cutting odontotripsis is very fast, if formation hardness surpasses 10Mpa, reamer is difficult to work, cause the rig torque overload easily, and low when high during moment of torsion, change greatly, impact, transmission system injury to rig is big, big to drilling tool infringement, in addition, to the rock stratum gnaw cut inhomogeneous, it is not of uniform size to cause cutting the landwaste that gets off, wherein big landwaste is difficult to be discharged by the mud suspension, causes bit freezing, even causes the engineering failure.
Summary of the invention:
The purpose of this utility model provides a kind of rock reamer with the spiral centralizer, and the rock reamer of described this band spiral centralizer will solve reamer in the prior art and be difficult to the technical problem of working in the high rigidity rock.
The rock reamer of this band spiral centralizer of the present utility model is made of an axle and a barrel-shaped body, described axle is arranged on the central axis of barrel-shaped body, wherein, the front end of described barrel-shaped body is provided with a transition-cone, the circumferential cutting gear wheel bracing frame that is set with two above numbers in the excircle upper edge of barrel-shaped body, all be provided with a cutting gear wheel in any one described cutting gear wheel bracing frame separately, the excircle of the barrel-shaped body in cutting gear wheel bracing frame the place ahead is provided with the spirality centralizer, described spirality centralizer is made of the spiral-shaped plate of two above numbers, and the along the circumferential direction uniform setting of described spiral-shaped plate is also fixedlyed connected with barrel-shaped body.
Further, described cutting gear wheel links to each other with cutting gear wheel bracing frame by rotating shaft.
Further, be inlaid with wear-resisting alloy block on the described cutting gear wheel.
Further, the outer wall of described transition-cone is welded with wear-resistant alloy layer.
Further, the outer wall of any one described spiral-shaped plate all is welded with wear-resistant alloy layer.
Further, the quantity of described cutting gear wheel is more than 6.
Further, the hand of spiral of described spirality centralizer is identical with the direction of rotation of described axle.
Further, the quantity of described spiral-shaped plate is more than 6.
Operating principle of the present utility model is: axle is connected the back and obtains power with rig, transition-cone guides barrel-shaped body to enter the pilot hole that gets out in advance, alloy block extruding on the cutting gear wheel and grinding rock, cut gear wheel simultaneously in stressed passive rotation later on, effectively reduce the torsion that rig need apply, and the peak value scope of change in torque is also dwindled greatly, reduced when boring rock impact to the relevant system of rig and drilling tool, prolonged mechanical application life, spirality centralizer on the barrel-shaped body plays the centering effect, the hole that this one-level is expanded keeps concentric with the upper level hole, and the cutting stability under loading of reamer expands the hole gauge that then.Space between spirality centralizer and the cutting gear wheel constitutes feeding funnel, the rock slag that enters this space is delivered to the cutting gear wheel further to grind on every side, simultaneously, wear-resistant alloy layer on the spiral template can smash big sillar, make it enter cutting gear wheel district and further grind to form landwaste, suspend by mud at last and discharge, realized the function that deslagging is removed obstacles, respond well to hardness less than the lithostratigraphy of 140Mpa.
The utility model and prior art contrast, and its effect is actively with tangible.The utility model is provided with cutting gear wheel and spirality centralizer in reamer, by the cutting gear wheel rock grinding is realized reaming can reducing the impact to rig and drilling tool prolonged mechanical application life, the spirality centralizer has the function that deslagging is removed obstacles, and prevents bit freezing.
