Description
Technical field
The present invention relates to anti-well drilling rig technique field, more particularly to a kind of wagon drill with safety supporting device.
Background technology
In soft rock mine construction, small pilot shaft method is excavated using Traditional Man and carries out vertical shaft and slope construction, with underground
The shortcomings of water discharge is difficult, difficulty of slagging tap is big, ventilation condition is poor, interchange operation construction safety is difficult to ensure that up and down so that
Vertical shaft and slope construction difficulty are increased, and especially the vertical shaft of the discrepancy in elevation or length more than 100m and slope construction are even more difficult.
It is the few construction technology of a kind of safe efficient, economy, short time limit, resource distribution using anti-well drilling machine construction pilot shaft.
Anti- well rig is mainly made up of wagon drill, pump truck and operation car, in addition also drilling tool and aid.1) rig
Car is the main frame of rig, and drilling cramp and rig flatcar are by together with hinge, when rig is erect, main hydraulic cylinder reverse propulsion,
Just drilling cramp is erected, leveling drilling cramp and locked with lower support, then by upper branch support jail, pulled down frame pull bar, improvement is installed
Disk is hung, manipulator, front and rear pull bar, just can be crept into.2) pump truck by fuel tank, Main Hydraulic Pump, pay hydraulic pump, it is motor, cold
But device, suck back the composition such as oil strainer, flatcar, oil pump systems convert electrical energy into hydraulic energy, be constantly supplied to behaviour deposit platform and
Each executing agency, completes drilling work.3) operation car is made up of operating desk, seat and flatcar, and operating desk is a frame structure, inner
Face is mounted with various control valve, pressure gauge, and in addition to rotating disk is hung in and operated on wagon drill, the action of other all mechanisms is grasped herein
Make to control on platform.4) drilling tool includes guide hole drill bit, reaming bit, perforate drilling rod, stable drilling rod and common drilling rod etc..5) auxiliary is set
It is standby mainly to have：Slush pump, immersible pump, waterwheel etc..6) other related facilities include：Anti- well rig concrete basis, for fixing anti-well
Rig and in this, as operating platform；Detritus tank and mud circulatory pool, deslagging and circulation are crept into for slurry (water) for guide hole；Steel plate
Water tank, is mainly used in main frame cooling periodical feeding.
Anti- well rig boring principle is the motor belt motor hydrodynamic pressure motor by rig, fluid motor-driven tap, and profit
Drilling system is delivered torque to hydraulic power, the hobboing cutter on drilling tool rotation, guide hole drill bit or reaming bit is driven in the pressure of the drill
In the presence of, pure rolling or micro sliding are done along bottom rock working face, while the axial direction that main frame oil cylinder is produced is drawn, pressure,
Acted on by unit head, drilling rod on guide hole drill bit or reaming bit, the hobboing cutter of guide hole drill bit is rolled under the pressure of the drill effect, production
Raw impact load, makes hob teeth produce impact, extruding and shear action, fractured rock to rock.Deslagging when guide hole is constructed：Using
Slush pump injects high pressure flushing liquid in drilling rod, then is extruded from the osculum of drill bit, by annular of the rock ballast between drilling rod and hole wall
Space drains into ash pit.Descend adit to unload guide hole drill bit after guide hole insertion again, and reaming bit is installed, then bottom right is expanded upwards
Hole, rock ballast washing away through supercooled water and deadweight during reaming are fallen to lower adit.
In addition, with the expansion in nearly Horizontal Directional Drilling application and field, construction bores the stratum met and is presented many
Sample, different type coal rock layer and adjoining rock are changed into from hard and above coal seam in single.Nearly horizontal orientation long drilled holes exist
When extending in the bad grounds such as soft broken, water sensitivity, there is that wall stability is poor, pore-forming difficulty big, easily occur bit freezing
Etc. drilling accident the problem of, have a strong impact on drilling track control and borehole engineering purpose realization.
When rig is operated, to prevent it from significantly swinging, upper supporting mechanism is provided with the upper end of drilling rod, its middle part is arranged with
Leading truck, its underpart is provided with lower supporting mechanism, and existing supporting mechanism, it is only for do not put the bottom of stable drilling rod
It is dynamic, but the drill bit of drilling rod lower end is when starting drilling, the airborne dust in some drilling is easily kicked up, and the rubble of generation easily splashes, to week
Surrounding environment causes great destruction；And have at present supporting mechanism can will drilling block, be unfavorable for drill hole of drilling machine, in addition, withdrawing
All it is manually to fix lower branch with the lower support screw of spanner dismounting in order to avoid lower support structure glides in anti-well drilling machine construction
Support, and being frequently encountered in particular location because limited space problem prevents big spanner from flexibly unloading screw, lose time and
Manpower and materials.
The content of the invention
The technical problems to be solved by the invention are significantly to swing what is caused when how to overcome existing rig to operate
Drilling rod skew, drilling are blocked, the defect such as easy downslide of lower support structure in anti-well drilling machine construction is withdrawn.
In order to solve the above-mentioned technical problem, the invention provides a kind of wagon drill with safety supporting device, including peace
Full support meanss, the safety supporting device includes drilling cramp and hydraulic leg, and the hydraulic leg includes multiple upper hydraulic legs
