Abstract
A support-type continuous digging machine for coal road or half-coal-and-half-rock road is composed of an improved digging machine and a supporting stack type hydraulic support. Its main body is fixed onto the base of hydraulic support, which is also used as the slide shoe for making the digging machine to run. The front and back hydraulic supports with two hydraulic jacks are used for automatic running. The roof suporting can be performed behind the support while the coal road is continuously dug.
Description
Affiliated technical field:
This machine is a tunnelling equipment under the coal mine.
Technical background:
In the tunnelling equipment, do not prop up protective function under the present existing coal mine, it also is caterpillar moving; the big gun head is flexible limited, in tunneling process, can not work continuously; often need to shut down to carry out roof timbering, have a strong impact on the driving progress, also have hidden danger at secure context.
Summary of the invention:
This supporting type continuous tunnelling machine is a kind of heading equipment by development machine that has improved and hydraulic support combination, is applicable to the continuous driving of coal road and half coal rock tunnel.Have a protective function, and can walk automatically, machine works is stable, can work continuously, and does not need to shut down supporting, and driving speed and safety are improved.
This machine adopts the support hydraulic chock to do supporting, main body is to be fixed on the hydraulic chock base, this base is again the walking piston shoes of supporting type development machine, working stability, the scope of activities of big gun head and rake pawl is big, is three two-speed transmissions owing to what adopt, so, big gun head its power when low cruise does not subtract, and is fit to the alternate heading operation more.Automatically two hydraulic jack of two hydraulic supports were stretched and are realized before and after walking was adopted, and when working continuously, can do roof timbering in the support back.
The cantilever of this machine body about, about movable in, flexiblely can reach 1400mm, the motion of rake pawl is that hydraulic system is controlled automatically, can be vertically, horizontal movement, angle, the scope of activity are big, effect of loading coal is good.The width of hydraulic support, highly more can adapt to the driving of large section roadway, climbing can reach 90 degree near 40 degree, angle of turn, meets the driving demand of Modern coal mines.
At present, in the middle of coal mine development machine, employing be mostly import equipment or external patented technology, and in the use of reality, the stability of driving speed and machine is all poor.132 development machines do not prop up protective function, not flexible of cantilever, and because it is the crawler type walking differential force that advances, the accident rate height in the work.Though S100 development machine cantilever can stretch; but the 510mm that can only stretch, other is similar with 132 development machines, all is in tunneling process; after essential employing is shut down; withdraw from development machine and carry out artificial supporting again, can resume work again after finishing artificial supporting, obviously influence driving speed; in addition; their rake pawl is short, and scope of activities is little, the weak effect of coalingging.
This supporting type continuous tunnelling machine is exactly at the above deficiency in the present development machine, by improving and combination, realizes improving driving speed and safety.

Fig. 2 is a vertical view
Main body is fixed between two piston shoes; In telescopic arm inside one flexible jack is arranged, do not reflect among the figure; The big gun head can all around, move up and down, the rake pawl can about, automatic loading of coal (do not reflect among the figure, this machine is positioned at main body, between two piston shoes, approaches the floor) on the bendable type scratch board conveyor up and down; The upright face of staying of front and back support all has seat-box location (have in the seat-box certain thickness rubber reset layer).
In the work, the big gun head should stop to harrow pawl work (otherwise, big gun head and the rake pawl phenomenon of fighting is arranged) when hindering the rake pawl movable, on the contrary, begin to harrow the work of pawl again when not influencing.
If, add the picking-up device of the canopy of putting on the shelf at after-poppet, just can alleviate the labour intensity of roof timbering greatly, accelerate support speed.
Implementation method:
What adopt because of this machine is a kind of heading equipment of development machine and hydraulic support combination, and development machine and hydraulic support all are the equipment that can produce at present.So, in implementing manufacture process, can produce fully.
Claims (6)
1, the continuous heading equipment formed by development machine that has improved and hydraulic support of supporting type continuous tunnelling machine.
2, according to claim 1, these facility have the characteristics of supporting, walking and continuous operation, do not need to shut down to do roof timbering specially, and roof timbering can carry out at any time in the support back.
3, be fixed on the hydraulic support foundation according to claim 1, development machine, the scope of activities of flexible amplitude of the cantilever of development machine and big gun head, rake pawl is all bigger, gearbox adopts three two fast big gun heads power when low speed not subtract, and the motion of rake pawl is by hydraulic system control automatically.
4, according to claim 2, transporter can crooked and slip between the piston shoes below the main body.
5, according to claim 2, this machine adapts to climbing near 40 degree, 90 degree of turning, the continuous excavation operation of coal road or half coal rock tunnel.
6,, can also load onto the picking-up device of a roof timbering in the back of support according to claim 2.
