Description
Technical field
The invention belongs to Roadway Support Technology field more particularly to mine anchor rod hole screw drive formula reaming drilling rods.
Background technology
Anchor pole has the characteristics that simple in structure, easy for construction, adaptable for underworkings supporting.Thus anchor in recent years
Bar supporting has become the major way of roadway support, but the failure mode of anchor pole is main in the engineer application of suspension roof support
It is whens encountering the coal ash adhered on hole wall or broken soft country rock etc. in Bracing Process in anchoring procedure between anchor pole and hole wall
Sliding unstability.
Destabilization problems are slid in view of anchor pole, some scholars attempt to solve problems using bolthole reaming mode, but
Existing reaming equipment is mostly that tool parts passively open cutting rock and lead to reaming poor performance, and there are institute's reaming is unstable,
The problems such as cutter recycling is difficult.It is therefore proposed that a kind of easy to use, the reaming drilling rod that reaming performance is stablized becomes a new direction.
Invention content
The present invention provides a kind of mine anchor rod hole screw drive formula reamer to solve shortcoming in the prior art
Bar is realized using mechanical whorl transmission principle and bolthole hole wall or bottom hole is carried out reaming and make institute's reaming in inverted conical
Device, the active that cutter may be implemented is stretched out and recycling.It can realize during the anchoring support of tunnel to anchor-holding force of anchor bolt
It improves, so as to improve anchor rod anchored property, anchor pole is overcome to slide unstable phenomenon, it is final to realize the efficient supporting of mine safety, it improves
Mine safety production is horizontal.
In order to solve the above technical problems, the present invention adopts the following technical scheme that：Mine anchor rod hole screw drive formula reamer
Bar, including broad, casing, push-pull rod, drilling machine connecting shaft and push-and-pull drive sleeve, push-pull rod is coaxial to be arranged in casing
Interior, casing and push-pull rod are horizontally disposed with along the longitudinal direction, and broad rear end is connected to push-pull rod front end, casing front side center
Symmetrical to offer two slot holes opened up along casing axial direction, casing front end is provided with for driving broad to stretch out length
The top pressure structure that hole radially expands, the coaxial riffled tube for being fixedly connected with internal diameter and being more than casing in casing rear end, push-and-pull driving
Sleeve is coaxial to be stretched into and is threaded in riffled tube, and the rear end for pushing and pulling drive sleeve is provided with handle, pushes and pulls rod rear end
Sequentially pass through after riffled tube and push-and-pull drive sleeve with drilling machine connecting shaft front end is coaxial is fixedly connected, drilling machine connecting shaft outer circle
Week is provided with external thread structure；Be provided on push-pull rod in riffled tube and with the top pressure cooperation of push-and-pull drive sleeve front end
Guide block is driven, the Maximum turning radius of guide block is driven to be more than the internal diameter of push-and-pull drive sleeve and the internal diameter less than riffled tube, set
Inside pipe wall is fixedly installed at least two guide sleeves being set in outside push-pull rod, and the outer diameter of push-pull rod is equal with the internal diameter of guide sleeve.
Top pressure structure includes baffle and addendum cone, and baffle is fixed at the front end of casing, addendum cone rear end and baffle front side
Face is fixedly connected, and broad includes the first reaming blade and the second cornish bit for radially corresponding to a slot hole respectively
The rear end of piece, the first reaming blade and the second reaming blade is hinged on push-pull rod front end by axis pin, and addendum cone is in preceding thick metacone
Pyramidal structure, the first reaming blade and the second reaming blade constitute scissors shape, addendum cone rear portion extend into the first reaming blade and
Between second reaming blade, torsional spring is arranged on axis pin, two spring arms difference top pressure the first reaming blade of torsional spring and second are expanded
Hole blade, under the action of torsional spring, addendum cone respectively with the first reaming blade and the second reaming blade press fit, the first cornish bit
The outside of piece and the second reaming blade is both provided with stair-stepping diamond cutter tooth, the first reaming blade and second along its length
The thickness of reaming blade is adapted to the width of slot hole.
One of them, which is led, is set on rear side of slot hole, another guide sleeve is arranged on front side of riffled tube.
It is provided with replaceable axle sleeve between push-and-pull drive sleeve inner wall and push-pull rod outer wall.
Using above-mentioned technical proposal, the present invention at work, first in the present invention drilling machine connecting shaft and drilling machine it is dynamic
Power output shaft is threadedly coupled.Then in bolthole casing push-in accomplished fluently in advance, handle rotation is stirred, drives push-and-pull actuating sleeve
Cylinder rotation is simultaneously moved forward along riffled tube, and push-and-pull drive sleeve pushes driving guide block to march forward, and driving guide block drives push-pull rod
Forward, the first hinged reaming blade of push-pull rod front end and the second reaming blade move forward, since casing is motionless, with first
Reaming blade and the second reaming blade move forward, and the addendum cone of casing front end is open-top by the first reaming blade and the second reaming blade
And stretch out two slot holes and stretch out, the first reaming blade and the second reaming blade cut rock stratum.Then drilling machine is started, is connected by drilling machine
Spindle high speed rotation, drilling machine connecting shaft drive push-pull rod rotation, the first reaming blade and the second reaming blade on push-pull rod with
Rotation and drive sleeve rotating, the diamond cutter tooth of the first reaming blade and the second cornish bit on piece expands foot of hole to one
A conical tank.In addition, really up to the mark in rock stratum, can first by push-pull rod be pressed onto resistance it is larger when just start drilling machine reaming, so
After stop drilling machine, being then rotated further by handle makes the first reaming blade and the second reaming blade continue to open, repeat this process two arrive
Reaming can be realized three times.Finally stop drilling machine, negative direction rotational handle is turning round the first reaming blade and the second reaming blade
It is retracted into casing along slot hole under the action of spring, finally extracts the work that ream operation can be completed in casing.
Torsional spring in the present invention plays the role of resetting in the first reaming blade and the second reaming blade to casing.Guide sleeve and
Axle sleeve plays the role of being oriented to push-pull rod back-and-forth motion.Guide block wherein on rear side of slot hole is played stops coal petrography in reaming procedure
Clast enters the effect in casing.
The Maximum turning radius of guide block is driven to be more than the internal diameter of push-and-pull drive sleeve and the internal diameter less than riffled tube, in this way
The position of forward movement can be limited, i.e., when driving guide block with end in contact after casing, cannot be moved further along.
Bolthole hole wall or bottom hole are carried out in conclusion the present invention provides a kind of realized using mechanical whorl transmission principle
The drilling rod of reaming, the present invention is easy to operate, and cost is relatively low, and reaming performance is stablized, and cutter can actively be opened and effectively be recycled.Energy
Anchor pole Problem of Failure caused by enough sliding unstabilitys effectively solved between anchor pole and hole wall, can improve mine safety situation, carry
High shaft production efficiency realizes that safety and high efficiency is of great significance with supporting to mine.
