Description
Technical field
The invention belongs to underground coal mine developing equipment technical field, be particularly 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
In underground coal mine developing equipment technical field, the traditional handicraft mode of all kinds of mine stone drifting is mainly big gun pick, and support pattern is anchor pole, anchor cable, joist, anchor net combination supporting.Big gun pick is the perforating of gas leg type air drill, powder charge, blows out; Blow out the spoil fallen, first adopt rock rake to transport work plane again by hand breaking; After work plane spoil cleans out, monomer air drill is used to carry out bolting and rope support.Mainly there is following problem in this stone drifting construction method of blowing out:
1, tunnelling section is little: excavated section, generally at about 15 ㎡, when head-room is more than 2m, just must 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 monomer air drill, and assisting anchor rod and anchor cable construction adopts jackhammer, the thrust of perforating derives from arm and the arm of people, 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 construction section is more than 2m height, must builds and remove scaffold, needing a large amount of time; Spoil width, more than just necessary hand breaking during 300mm, takes a large amount of time, otherwise can destroy main delivery system.Integral construction advance of working cycle is low, all within 2m;
4, efficiency is low: because perforating, broken spoil, bolting and rope support are manual work, constructor is many, causes operating efficiency low;
5, safety factor is low: constructor is interlocked in high-altitude operation, and job safety environment is poor.The all operations under sky top of perforating, broken spoil, bolting and rope support, also exist potential safety hazard;
6, operating environment is poor: the dust when blasting fume after blowing out and whitewashing all easily causes the PUD D of constructor, affects the health of operating personnel.
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, 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 driving 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 the stone drifting difficult problem that complex process, driving progress are slow.
For this reason, the present inventor is devoted to the developmental research of underground coal mine machinery, devise comprehensive mechanized rock roadway tunneling machine group at present, primarily of comprising track unit, belt conveyer part, the frame be arranged on track unit, anchor bar anchor cable rig, operating desk and hydraulic pressure and control system, at least one topping machanism and swinging up and down thrust unit, temporary lining and front fastening devices and posterior fixation devices.Described transport section is made up of rake pawl, belt conveyer, on the front that its rake pawl is contained in described track unit and shovel board; Belt conveyer is arranged on the rear of shovel board and the centre in crawler travel portion; Described operating platform, hydraulic pressure and operating system are contained in the top of frame.But not wide popularization and application, its reason is that product is also immature.Through actual motion verification experimental verification, this owner to also have problems following some:
1. comprehensive mechanized rock roadway tunneling machine group topping machanism with swing up and down thrust unit part, in stone drifting, cutting power is also lower; In stone drifting, compliance is poor.
2, the advanced stand device supporting height of comprehensive mechanized rock roadway tunneling machine group is lower, and majority is with development machine in conjunction with imperfect, and volume after folding is larger, and poor to the compliance of top board, bad adaptability when particularly top board tilts more serious.
3. comprehensive mechanized rock roadway tunneling machine group is exposed in frame all the time at its anchor bar anchor cable rig of the work progresss such as walking, driving cutting and temporary lining, affect the operation of these operations, easily be subject to rock hit and damage, the structure design of anchor bar anchor cable rig and installation site are not too reasonable.
4., when comprehensive mechanized rock roadway tunneling machine group works, concerning complete machine, only rely on this backplanes support assembly support and stablize, its effect is not ideal, and stablizing effect is poor.
For this reason, comprehensive mechanized rock roadway tunneling machine group, through actual motion verification experimental verification, is necessary to carry out technological improvement and perfect very much.
