Description
Technical field
The invention belongs under the coal mine and open up equipment technical field, particularly be applicable to the rotatable flexible cutting means of the comprehensive mechanization stone drifting unit of rock gangway mechanization developing operation under the large, medium and small moulded coal mine.
Background technology
Under coal mine, open up equipment technical field, the traditional handicraft mode of all kinds of mine stone driftings is mainly the big gun pick, and support pattern is anchor pole, anchor cable, joist, anchor net combination supporting.The big gun pick is the perforating of gas leg type air drill, powder charge, blows out; Blow out the spoil that falls, adopt rock rake to transport work plane again through hand breaking earlier; After the work plane spoil cleans out, use the monomer air drill to carry out the anchor shaft anchor cable supporting.Mainly there is following problem in this stone drifting job practices of blowing out:
1, the tunnelling section is little: excavated section generally about 15 ㎡, when head-room surpasses 2m, must just can carry out top-assisting anchor rod and anchor cable construction by scaffolding;
2, speed of application is slow: when the construction section surpasses the 2m height, must build and remove scaffold, need great amount of time; Just must hand breaking when the spoil width surpasses 300mm, spend great amount of time, otherwise can destroy main fortune system.The integral construction advance of working cycle is low, all in 2m;
3, efficient is low: owing to perforating, broken spoil, anchor shaft anchor cable supporting are manual work, the constructor is many, causes operating efficiency low;
4, safety factor is low: the constructor is staggered operation in the high-altitude, and the job safety environment is poor.Perforating, broken spoil, anchor shaft anchor cable supporting be operation under the sky top all, exists potential safety hazard;
5, operating environment is poor: the dust when blasting fume after blowing out and whitewashing all causes constructor's PUD D easily, influences operating personnel's health.
Many in industry scientific and technical personnel are constantly for improving the technical level of rock gangway mechanization developing operation; Improve execution conditions and construction technology and effort; Anchor bar anchor cable rig part, hydraulic pressure and the operating system that a kind of " stone drifting and supporting construction rig " comprises track unit and belt transport section, temporary lining and the broken petrosa branch of rake rock, two liftables and swing is disclosed like one Chinese patent application numbers 200820077065.6.This equipment has three pedestals that are used for fixing oil cylinder on operating platform, wherein two pedestals are used for fixing anchor bar anchor cable rig part, and a pedestal is used for fixing temporary lining and the broken petrosa branch of rake rock.The pedestal that temporary lining and the broken petrosa of rake rock divide is in the centre of operating platform, and the pedestal of the anchor bar anchor cable rig of described two liftables and swing part is in the both sides of operating platform.Though it changes into the technical equipment of cover for realizing the construction of large, medium and small rock roadway in coal mine driving borehole, top-assisting anchor rod and anchor cable construction, broken rock rake rock, detritus transportation, temporary lining machinery; Realize safety in production for large, medium and small colliery and created the most basic condition; But------line--is blown out and--is broken rock and--harrow--mucking--temporary lining--anchor bar anchor cable supporting---whitewashing of rock fortune rock in powder charge in warning because construction technology is: perforating.Still can not break away from the traditional handicraft of the rock of drilling and blasting brokenly, still can not solve complex process, the slow stone drifting difficult problem of driving progress.
For this reason; The inventor is devoted to the developmental research of colliery down-hole mechanical; Designed comprehensive mechanization stone drifting unit at present, mainly by comprise track unit, belt conveyer part, be installed in fuselage on the track unit, anchor bar anchor cable rig, operating desk, and hydraulic pressure with control system, at least one topping machanism and swing up and down thrust unit, temporary lining and preceding fastening devices, reach posterior fixation devices.Described transport section is to be made up of rake pawl, belt conveyer, and its rake pawl is contained on the place ahead and shovel plate of described track unit; Belt conveyer is installed in the rear of shovel plate and the centre of crawler travel portion; Described operating platform, hydraulic pressure and operating system are contained in the top of fuselage.But wide popularization and application not, its reason are that is that all right is ripe for product.Through the actual motion verification experimental verification, the topping machanism of this machine with swing up and down the thrust unit part, mainly also existing problems have following some: 1, cutting power is also lower in the stone drifting; 2, compliance is relatively poor in stone drifting; 3, combine with development machine imperfect.
