Description
Technical field
The present invention relates to Boring Machine Technique field more particularly to a kind of cantilevered longitudinal axis development machine and its tunneling construction sides
Method.
Background technique
Coal roadway tunneling construction is one of movable main contents of coal production, and the height of tunneling construction drilling depth level directly closes
It is the digging succession relation and economic benefit to coal mine.Coal roadway tunneling construction drilling depth level is generally also relatively low at present, especially
In the general situation of top plate (including rock and coal) stability, drill footage per month is not horizontal universal high, mostly 200~300m it
Between, lead to that coal mine coal road tunneling construction employment is more, head are more for construction, safety management difficulty is big, at high cost, this situation urgently changes
Become.
Traditional cantilevered longitudinal axis development machine, which emerges, has about 70 years history, which has structure simple, reliable, adds
Work manufacture is relatively easy, and at low cost, adaptability is good, installs and withdraw from a series of advantages such as workload is small, but there is also because of knot
Cutting caused by structure defect, load, chassis is frequently moved in transport process, the used time is too long, production efficiency is low, and is difficult to realize
The outstanding problems such as cutting course automation control.
In order to overcome above-mentioned series of malpractice, on the basis of declaring double cutting units patents, the applicant is again in middle promulgated by the State Council
A kind of cantilevered longitudinal axis development machine is disclosed in bright patent application CN107461194A, by the vertical revolution hinged with revolving body
The connection type on hinged shaft and chassis is provided with perpendicular under the action of driving device by the fixed laterally slidable technology that is changed to
To revolution hinged shaft slide unit laterally moved relative to development machine chassis, thus by revolving body drive longitudinal axis cutting units relative to
Chassis laterally moves, and can increase tunneling machine cutting span length without development machine chassis transverse shifting, realize development machine
Chassis is cut relative to the located lateral of institute's construction tunnel center line, to significantly improve tunneling construction efficiency, and is mating top
Plate gib hydraulic support creates advantage.
But in terms of material scraper dress is with transhipment, since conventional boom-mounted longitudinal axis development machine uses always " shovel board+star-wheel "
Or the loading attachment of " shovel board+raking pawl " is installed on shovel as shown in fig. 6, the tail sprocket wheel of scratch board conveyor C and shovel board A are overlapped
Material is transported to scratch board conveyor C from shovel board by the star-wheel or raking pawl B of plate A.The motionless loading width of chassis located lateral because
To be limited by star-wheel or raking pawl diameter, it can not arbitrarily be increased according to tunnel span, need to tunnel in loading process
The chassis of machine had both wasted time reduction by the way that frequently horizontal and vertical movement could complete whole materials loadings in tunnel in this way
Production efficiency, and rub stone roller and be broken roadway floor；The original that star-wheel or raking pawl diameter can not arbitrarily be increased according to tunnel span
Because being, if increased to adapt to tunnel span by star-wheel or the enlarged diameter of raking pawl, this just increases shovel board preceding simultaneously
Size in rear direction is bound to accordingly to lengthen vertical in order to avoid the interference of longitudinal axis cutting units and shovel board and star-wheel or raking pawl
Axis cutting units, but it is infeasible for being limited lengthening longitudinal axis cutting units by many-sided reason.Therefore, for the mating this longitudinal axis
Cutting units " horizontal sliding " technology, it is necessary to which the structures and methods for filling transhipment loading attachment to its material scraper improve, simultaneously
The advantage of longitudinal axis cutting units " horizontal sliding " is set to be not fully exerted.
