Description
Technical field
The utility model belongs to mine engineering equipment technical field, be related to it is a kind of for coal road hard rock driving operation set
Standby, in particular to a kind of digging diameter is small, is able to carry out section of jurisdiction and anchor pole steel mesh Mixed support, is suitable for weak broken stratum
Long distance driving, operating efficiency is high, safe and reliable small-sized mining hard rock shield excavation machine.
Background technique
Traditional coal road hard rock mole supports boots by cutterhead, main driving, shield, crossbeam, propelling cylinder, and belt feeder, rear portion is matched
Set, the composition such as hydraulic system and electrical system；The rock stratum that hardness f value is greater than 10 can be excavated.Its working principle is that: cutterhead rotation
Turn cutting rock, and using the scraper bowl on cutterhead, the carg cut down is collected on the belt feeder in centre, into
And carg is transported to by heading equipment rear portion by belt feeder, transports working face.And the support boots being supported on the wall of hole are relied on,
Forward for heading equipment provides counter-force, using propelling cylinder it is flexible by cutterhead, main driving, this three big component of crossbeam is toward being pushed forward
Into a stroke；And then carry out changing step, it may be assumed that support boots retraction, rear support supports boots and lifts entire support boots, oily using promoting
Cylinder will support boots and draw one stroke of shifting forward, realize and change step.
However, limitation of the existing coal road hard rock mole due to structure, supportting between boots and support boots is connected by cross pin shaft
It connects, not only supportting boots, structure is complicated, and is enclosed construction in the middle part of shield body, and maintenance personnel can not pass through.So existing structure
Coal road hard rock mole digging diameter can only be suitble to be greater than 3.3 meters or more of tunnel；If digging diameter is less than 3.3 meters, personnel
It can not then pass through from therebetween, and then influence conventional maintenance and tool changing.In addition, then needing a pipe sheet assembling in main drive to flat section of jurisdiction
It moves behind shield, and there are also support boots behind shield, since section of jurisdiction can not be by supportting boots, so assembled after shield can not just manage
Piece, and support boots cannot support on section of jurisdiction, therefore the type of existing coal road hard rock mole is merely able to be equipped with jumbolter, can not be equipped with
Duct piece assembling machine；So as to cause when development machine encounters weak broken stratum, then can not normally tunnel.Meanwhile traditional coal road
Hard rock mole is open type design mostly, main driving top is only provided with shield, the design of anchor pole mechanism is protected in main driving
Between shield and support boots, between the anchor pole mechanism and support boots and rear portion of support boots does not have shield structure, other auxiliary is caused to set
Standby to be exposed among the rock stratum after excavating, there are security risks.Therefore it is necessary to the coal road hard rock heading equipments to the prior art
It is improved.
