Abstract
The invention provides a cutter of a comprehensive mechanized rock tunnel boring machine. The cutter mainly comprises a cutterhead, conical hobs, conical hob shafts, hob bearings and a hob shaft seat, wherein the hob shaft seat is installed on the cutterhead; the conical hob shafts and the hob bearings are arranged in the conical hobs; and the conical hob shafts are installed in the hob shaft seat. The cutter has the following beneficial effects: the cutter can be used for improving the mechanized construction level of rock tunnel boring in the mine, is an important work part of the rock tunnel boring machine in the mine, has a compact structure and working stability and reliability, can be used for substantially improving the development work efficiency to be about three times that of rock tunnel blasting boring, can cut rock strata with hardness higher than the grade 8, breaks through the big problem that the hard rocks can not be cut and is suitable for the rock tunnel boring machines in the mines in various sizes.
Description
Technical field
The invention belongs to underground coal mine developing equipment, be applicable to the bite of large, medium and small type underground coal mine rock lane comprehensive mechanization developing operation comprehensive mechanized rock roadway tunneling machine used.
Background technology
In underground coal mine developing equipment technical field, as Chinese Patent Application No. 200820077065.6 disclose one " stone drifting and supporting construction rig " comprise track unit and belt-conveying part, a temporary lining and harrow that rock breaks that petrosa divides, anchor bar anchor cable rig part, hydraulic pressure and the operating system of two liftables and swing.This equipment on the operational platform face has three for the pedestal of fixed oil cylinder, and wherein two pedestals are used for fixing anchor bar anchor cable rig part, and a pedestal breaks petrosa for fixing temporary lining and rake rock and divides.Temporary lining and rake rock break pedestal that petrosa divides in the centre of operating platform, and the pedestal of the anchor bar anchor cable rig part of described two liftables and swing is in the both sides of operating platform.Though it is for realizing the construction of large, medium and small rock roadway in coal mine pick borehole, top-assisting anchor rod and anchor cable construction, broken rock rake rock, detritus transport, the mechanical technical equipment changing into cover of temporary lining, the most basic condition is created for large, medium and small colliery realizes safety in production, but---------line---is blown out and---is broken rock and---harrow rock and transport rock---mucking---temporary lining---anchor bar anchor cable supporting---whitewashing in powder charge in warning because construction technology is: perforating.Still can not break away from the traditional handicraft of rock of drilling and blasting brokenly, still can not solve complex process, the stone drifting difficult problem that driving progress is slow.
For this reason, people are devoted to research and develop the stone head development machine used in coal mine down-hole rock tunnel tunneling construction, be bite, be directly connected to equipment operating efficiency for stone head development machine job stability and the extremely important workpiece of reliability.
Summary of the invention
Object of the present invention solves above-mentioned coal mine down-hole rock tunnel tunneling construction Problems existing exactly, improves mechanized construction level further, provides a kind of compact conformation, and working stability, with reliable, improves the bite of the comprehensive mechanized rock roadway tunneling machine of drivage efficiency.
Technical scheme of the present invention is to achieve these goals:
The bite of comprehensive mechanized rock roadway tunneling machine, comprises cutterhead, conical hob, conical hob axle and cutter bearing, hobboing cutter axle bed; Described cutterhead fills hobboing cutter axle bed, conical hob axle and cutter bearing in conical hob, in cutter shaft dress hobboing cutter axle bed.
The conical hob of described bite has four, wherein: the conical hob of bite has four, wherein: have a single hobboing cutter axle bed sharp cone distal hobboing cutter in four described conical hobs, have a single cutter shaft seat stand conical hob, and two thread hob axle bed platform conical hobs; Described single hobboing cutter axle bed sharp cone distal hobboing cutter is contained on the first cut surface; Single cutter shaft seat stand conical hob is on the second cut surface; Two thread hob axle bed platform conical hobs are contained in respectively on the 3rd or the 4th cut surface, and described single hobboing cutter axle bed sharp cone distal hobboing cutter and single cutter shaft seat stand conical hob are arranged symmetrically with on cutterhead, and two thread hob axle bed platform conical hobs are being arranged symmetrically with too on cutterhead.
The present invention has significant beneficial effect:
The present invention is that coal mine down-hole rock tunnel driving improves mechanized construction level, is the important process parts of coal mine down-hole rock tunnel development machine, its compact conformation, and working stability is with reliable, and improve developing work efficiency significantly, is more than three times of rock-gangway bomb-dug work efficiency; Solve the rock lane comprehensive mechanical drivage difficult problem that Polodyakonov coefficient is greater than 8, fill up the blank of domestic hard rock mole tool.Be adapted to the comprehensive mechanized rock roadway tunneling machine of various big or middle and small-size coal mine down-hole.
