Description
Technical field
The utility model belongs under the coal mine opens up equipment technical field, particularly is applicable to the comprehensive mechanized rock roadway tunneling machine group of large, medium and small type coal mine down-hole rock tunnel mechanization developing operation.
Background technology
Open up equipment technical field under coal mine, 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 again rock rake to transport work plane by hand breaking first; After the work plane spoil cleans out, use the monomer air drill to carry out bolting and rope support.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, non_mechanical operation: borehole construction, spoil fragmentation are manual work, the top anchor shaft anchor cable construction of supported laneway still adopts the monomer air drill, and assisting anchor rod and anchor cable construction adopts jackhammer, and the thrust of perforating derives from people's arm and arm, and worker's labour intensity is large.Because assisting anchor rod and anchor cable construction mainly relies on manpower, the construction quality of assisting anchor rod and anchor cable can not fundamentally be guaranteed;
3, speed of application is slow: when the construction section surpasses the 2m height, must build and remove scaffold, need a large amount of time; Just necessary hand breaking had spent a large amount of time, otherwise can destroy main delivery system when the spoil width surpassed 300mm.The integral construction advance of working cycle is low, all in 2m;
4, efficient is low: owing to perforating, broken spoil, bolting and rope support are manual work, the constructor is many, causes operating efficiency low;
5, safety factor is low: the constructor is staggered operation in the high-altitude, and the job safety environment is poor.Perforating, broken spoil, bolting and rope support be operation under the sky top all, exists potential safety hazard;
6, operating environment is poor: the dust the when blasting fume after blowing out and whitewashing all causes constructor's PUD D easily, affects operating personnel's health.
For this reason, in industry many 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, disclose a kind of " stone drifting and supporting construction rig " such as Chinese patent application numbers 200820077065.6 and comprised track unit and belt-conveying part, a temporary lining and the broken petrosa of rake rock divides, anchor bar anchor cable rig part, hydraulic pressure and the operating system of two liftables and swing.This equipment has three pedestals that are used for fixed oil cylinder on operating platform, wherein two pedestals are used for fixedly anchor bar anchor cable rig part, and a pedestal is for fixedly temporary lining and the broken petrosa of rake rock divide.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 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 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 at present the comprehensive mechanized rock roadway tunneling machine group, mainly by comprise track unit, belt conveyer part, be installed in frame 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 front fastening devices, reach posterior fixation devices.Described transport section is to be made of rake pawl, belt conveyer, and its rake pawl is contained on the place ahead and shovel board of described track unit; Belt conveyer is installed in the rear of shovel board and the centre of crawler travel section; Described operating platform, hydraulic pressure and operating system are contained in the top of frame.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, this owner to also have problems following some:
The topping machanism of comprehensive mechanized rock roadway tunneling machine group with swing up and down the thrust unit part, cutting power is also lower in the stone drifting; Compliance is relatively poor in stone drifting.
2, the advanced stand device supporting height of comprehensive mechanized rock roadway tunneling machine group is lower, and majority is combined imperfect with development machine, and volume after folding is larger, and relatively poor to the compliance of top board, bad adaptability when particularly the top board inclination is more serious.
3. the comprehensive mechanized rock roadway tunneling machine group is exposed on the frame at its anchor bar anchor cable rig of the work progresss such as walking, driving cutting and temporary lining all the time, affect the operation of these operations, be subject to easily rock and hit and damage, the structure design of anchor bar anchor cable rig and installation site are not too reasonable.
4. when the comprehensive mechanized rock roadway tunneling machine group is worked, concerning complete machine, only rely on this backplanes support assembly to support and stablize, its effect is not ideal, and stablizing effect is relatively poor.
For this reason, the comprehensive mechanized rock roadway tunneling machine group is necessary to carry out technological improvement and perfect through the actual motion verification experimental verification very much.
