Description
Technical field
It is particularly a kind of itself to have the continuous miner of branch protective function and use the present invention relates to coal mining equipment
The method that continuous miner is mined.
Background technology
Continuous miner is a kind of comprehensive coal excavation apparatus for integrating cut, walking, loading and dedusting, is mainly used for
The exploitation of speedy drivage, room formula or the pillar mining in tunnel and corner coal etc..
Existing continuous miner itself, without branch protective function, is working in walking process, is depositing without supporting mechanism
At the top of tunnel country rock come off caused by production safety hidden danger.
The content of the invention
The object of the present invention is to provide it is a kind of itself have branch protective function continuous miner and with the coalcutter coal mining
Method effectively to avoid work safety accident caused by coming off due to tunnel top country rock, improves the security of coalcutter work.
In order to achieve the above objectives, the continuous miner itself with branch protective function provided by the invention, including by coalcutter
The coalcutter that fuselage, Walk Part of Shearer, winning machine cutting part, coalcutter shovel board portion and coalcutter Department of Transportation form；Its feature
It is：
Coalcutter is equipped with the supporting mechanism being made of main support bracket and auxiliary shoring frame；
Wherein main support bracket includes one group of main support bracket longeron of longitudinally spaced distributions；Support one group of main support bracket longeron
Main support bracket crossbeam；Control one group of main support bracket vertical hydraulic cylinder of main support bracket beam lifting；Main support bracket vertical hydraulic cylinder
It is fixedly connected by the mounting flange being welded on the coalcutter fuselage with coalcutter fuselage；
Wherein auxiliary shoring frame includes one group of auxiliary shoring of longitudinal direction distribution corresponding with the interval of the main support bracket longeron
Frame longeron；Support one group of auxiliary shoring frame crossbeam of auxiliary shoring frame longeron；One on auxiliary shoring frame crossbeam bottom surface
Group auxiliary shoring frame vertical hydraulic cylinder；The cylinder body of auxiliary shoring frame vertical hydraulic cylinder is by horizontal extension hydraulic cylinder and is welded on institute
The angle ear mount stated on coalcutter fuselage is connected；There is bearing plate in the lower end of auxiliary shoring frame vertical hydraulic cylinder.
It is with the method that above-mentioned continuous miner is mined：
When continuous miner is in coal mining state, main support bracket vertical hydraulic cylinder is in stretching state, main support bracket crossbeam
Raised configuration is in main support bracket longeron, main support bracket longeron reclines with roof rock；Horizontal extension hydraulic cylinder and auxiliary branch
Retaining frame vertical hydraulic cylinder is also at stretching state, and the bearing plate of auxiliary shoring frame vertical hydraulic cylinder lower end is contacted with ground, plays branch
Support acts on, and auxiliary shoring frame crossbeam and auxiliary shoring frame longeron rise, and auxiliary shoring frame longeron reclines with roof rock, with main branch
Retaining frame longeron cooperatively plays support action；
Continuous miner stops exploitation after having adopted one layer of coal, and then main support bracket vertical hydraulic cylinder retraction, passes through main supporting
Frame crossbeam declines main support bracket top beam, departs from roof rock；Hereafter continuous miner together with main support bracket to Forward
It is dynamic；During continuous miner moves forward, horizontal extension hydraulic cylinder synchronous is shunk, and auxiliary shoring frame vertical hydraulic cylinder is motionless at this time
Make, auxiliary shoring frame is to roof rock still in supporting state；When continuous miner is moved to before the next coal seam exploited
Stop motion, horizontal extension hydraulic cylinder is just also by setting stroke stopping contraction at this time；Then main support bracket vertical hydraulic cylinder
It stretches out, makes main support bracket crossbeam lifting, main support bracket longeron is contacted with roof rock, and supporting is carried out to roof rock；Main supporting
After the completion of frame lifting action, auxiliary shoring frame vertical hydraulic cylinder is shunk, before this auxiliary shoring frame crossbeam and auxiliary shoring frame longeron
Decline, depart from auxiliary shoring frame longeron and roof rock, auxiliary shoring frame longeron is down to that contacted with main support bracket crossbeam cannot
Continue decline when, bearing plate together with auxiliary shoring frame vertical hydraulic cylinder cylinder body then with auxiliary shoring frame vertical hydraulic cylinder after
Continuous contraction is lifted up, and bearing plate departs from ground, and auxiliary shoring frame exits supporting；After auxiliary shoring frame exits supporting, level is stretched
Contracting hydraulic cylinder is stretched out by setting stroke, and auxiliary shoring frame is elapsed forward；After passage, auxiliary shoring frame vertical hydraulic cylinder
Stretch out, land bearing plate, auxiliary shoring frame crossbeam and auxiliary shoring frame longeron lifting, auxiliary shoring frame longeron again with top plate
Country rock contacts, and common supporting is carried out to roof rock with together with the main support bracket longeron of roof rock contact contact with；So
Coalcutter starts the exploitation to next layer of coal afterwards；So Xun Huan realizes coalcutter during coal mining by main support bracket and auxiliary
The common supporting of support bracket by auxiliary shoring frame supporting in moving process, makes coalcutter begin in the recovery process in whole section of coal seam
Eventually in voluntarily supporting state；
After coalcutter terminates the exploitation in one section of coal seam, main support bracket and auxiliary shoring frame is made to pack up simultaneously, with roof rock
Depart from ground, then retract, next section of coal seam is exploited by above identical method of operation exploitation；And so on, directly
To the exploitation for completing whole coal seams.
Compared with existing continuous miner, continuous miner of the present invention is equipped with the supporting with branch protective function due to itself
Mechanism makes it can effectively avoid in entire mining process and is come off caused security incident by country rock at the top of tunnel, improves and mine
The security of machine work.
