Technical field.
Background technology
Coal accounts for the 70% of China's primary energy total quantity consumed, far above crude oil, water power, natural gas equal energy source, in China
Energy consumption structure in occupation of leading position.Set as the major mechanical that straight underground passage is dug in coal mining projects
Standby, development machine equally serves irreplaceable effect in the Transport Facility Constructions such as subway, highway, be middle-size and small-size tunnel and its
The main cutting machinery of his complicated subterranean strata.Development machine has safe efficient and good etc. excellent into lane quality in engineer applied
Point, but cost is big, and construction is complicated, and Pick Loss is also larger, difficulty, excavation cost, pick is tunneled in breaking up hard rock and is damaged
Consumption and degree of danger all will be lifted at double.
In sum, due to complex working condition, adverse circumstances, tunneling process can destroy original rock texture, affect tomography point
Cloth, directly results in rock stability, while tunnel producing a large amount of dust, causes visibility extremely low, is highly detrimental to work surface
Monitor in real time, it is difficult to note abnormalities in time, if now increasing auxiliary device to existing development machine, such as increase ultrasonic listening
The equipment such as instrument, infrared thermal imaging, carry out monitor in real time to rock crackle forming change, country rock temperature, it is determined that front rock is tunneled
Property, tunneling program is timely adjusted, the reactive loss in driving is reduced, reduces the probability that accident occurs.And for example increase secondary
The dust falling devices such as water spray reduce accident rate etc. to improve environment on coalface quality.
At present, also there are the improvement to development machine system, such as Chinese patent document " notification number CN in prior art
201460729U " discloses a kind of underground coal mine heading equipment, and specially a kind of anchor rod drill on tunneller solves traditional anchor
Bar drill machine cannot adapt to highly-mechanized comprehensive pick production problem, including slide rail and base installed in development machine upper middle position

Drilling cramp and drilling cramp expansion oil cylinder, drilling cramp expansion oil cylinder front end are hinged with drilling cramp, and telescopic arm front end end is fixed with drilling cramp revolution oil
Cylinder, drilling cramp angling cylinder are fixed with suspension bracket, increase suspension device, single function, huge structure, with headwork on development machine
The joint degree of the main boom of Main Function is poor.
Chinese patent document " notification number CN204225888U " discloses a kind of hardly possible that is applied to and moistens the quick comprehensive pick work in coal seam
Make the anti-dust falling system of efficient synthesis in face, including sized spray dust-suppression system, ventilating and purifying air system and control air control dirt system.Spray dust-arrest
System includes being installed on the annular external spraying device of development machine rocking arm root, the spraying being installed on above a fortune, two operating loading points
Device and the Dust collecting net for being installed on tunnel rear, ventilating and purifying air system include distributed dust shield, negative pressure skeleton air duct and dedusting
Blower fan, control air control dirt system is by slide rail, light air cylinder, reducing air duct, air duct bin, flexible skeleton air duct, air duct, tune wind
Valve, commutation wind pipe composition, using the labor operation environment of the system enhancement driving face, but the system structure and control be
System is complicated, single function.
Chinese patent document " notification number CN 202851001U " discloses a kind of flexible part of heading machine dustproof construction, including base
Plate, is fixed with support column below substrate, substrate one end is connected with the first coupling block, the other end is provided with the substrate baffle plate with guide rail,
The right shell body of substrate baffle plate and the first sliding panel termination coordinates, and the other end of the first sliding panel is provided with the right baffle-plate second with guide rail
Sliding panel one end be provided with right baffle-plate coordinate the second sliding panel baffle plate, the second sliding panel other end be fixed with the second coupling block and
3rd coupling block, the second sliding panel are provided with bolt.The utility model one end is connected on outer telescopic tube, and the other end is installed on to be stretched
On contracting protection cylinder, telescopic folding, but the system structure and control system complexity, single function, it is unfavorable for penetration and promotion.
In sum, currently available technology is also suffered from the drawback that：1st, single function, degree of flexibility are poor；2nd, to original driving
Machine changes larger, bigger for the development machine redesign workload of different model, is unfavorable for popularizing use；3rd, due to existing
In environment, digging laneway is height-limited, and above-mentioned development machine increased body height, may lead to not into being advanced into exploitation；
