Description

A kind of certainly creeping into can with expansion anchor pole hole-forming device
Technical field
The present invention relates to a kind of certainly creeping into can with expansion anchor pole hole-forming device.
Background technology
At present, for bolt anchorage rock-soil layer pore-forming, main employing air rock drill pore-forming or electric coal drill pore-forming.Air rock drill utilizes Pneumatic immpacting effect by crushing rock formation, and utilizes gases at high pressure air blast effect that formation debris is blown out hole; Electric coal drill boring is applicable to solve texture stratum and meets hammer drill Churn drill not easy-to-discharge slag problem in water softening problem and texture stratum, and in soil property class stratum, speed of fulfiling hole is very fast., all there is shortcoming and be in hole-forming device in above two kinds of bolt anchorage rock-soil layers: one is that pore-forming aperture is single, cannot realize reaming in pore forming process; Two is the fixing difficulties of anchor pole head, and after slip casting after skyhook pallet, only have anchor pole end stressed, bar structure and hole wall country rock, substantially without active force, lose anchorage effect.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of certainly creeping into can with expansion anchor pole hole-forming device.
Of the present invention certainly creeping into can comprise with expansion anchor pole hole-forming device: drill bit, twist drill rods, variable-frequency motor and high-pressure pump, twist drill rods one end is connected by screw threads for fastening with drill bit, the twist drill rods other end is connected with variable-frequency motor by swivel bolt, variable-frequency motor is provided with fixed handle, central through hole is axially arranged with in described twist drill rods, central through hole one end is connected with high-pressure pump by sebific duct, and the other end is connected with drill bit; Bottom described drill bit, drill bit vertical direction is provided with telescopic sharpener, bottom sharpener, spring leaf is installed.
Preferably, described drill bit uses at the bottom of airtight steel airtight, is equipped with rubber seal at the bottom of airtight steel and between twist drill rods.
Preferably, the described twist drill rods aperture with central through hole and sebific duct junction use sealing-plug to seal.
After the present invention switches on power, drill bit fast rotational kata-rocks soil layer, broken cutting takes boring out of voluntarily by twist drill rods, high-pressure pump is utilized in drill bit, to be filled with high pressure gas by central through hole, sharpener stretches out drill bit, and with bit expanded hole, after high pressure gas removal, sharpener is regained by spring force, can complete with boring with expanded hole in boring procedure, increase resistance after reaming position is mainly used in bolt grouting and block anchor head effect.
The present invention utilizes rotary drilling-head kata-rocks soil layer pore-forming, sharpener stretches out the broken hole wall reaming of drill bit, twist drill rods is used to rotate Completion of Drilling Hole and reaming is broken cuts in band portals, be applicable to rock matter and texture stratum fast drilling, efficiently solve rock-soil layer and meet water softening problem.This device creeps into and forms compound aperture, with groove in overall hole, as anchor head draw-in groove, makes anchor pole total length stressed and increase frictional resistance after slip casting, improves anchoring effect.
Accompanying drawing explanation
Fig. 1 can with expansion anchor pole hole-forming device structural representation for certainly creeping into;
Fig. 2 is drill bit structure schematic diagram.
Detailed description of the invention
As shown in Figure 1, the present invention includes: drill bit 2, twist drill rods 7, variable-frequency motor 10 and high-pressure pump 11, twist drill rods 7 one end is connected by screw threads for fastening with drill bit 2, twist drill rods 7 other end is connected with variable-frequency motor 10 by swivel bolt 9, variable-frequency motor 10 is provided with fixed handle 13, be axially arranged with central through hole 6 in twist drill rods 7, central through hole 6 one end is connected with high-pressure pump 11 by sebific duct, and the other end is connected with drill bit 2.
Bottom drill bit 2, drill bit 2 vertical direction is provided with telescopic sharpener 4, bottom sharpener 4, spring leaf is installed.
During work, drill bit 2 fast rotational kata-rocks soil layer 1, chip takes boring out of voluntarily by twist drill rods 7, high-pressure pump 11 is filled with high pressure gas by central through hole 6 in drill bit 2, make sharpener 4 stretch out drill bit 2, expand boring along with drill bit 2 rotates, after high pressure gas removal, sharpener 4 is retracted by spring leaf.
Like this, the size in controlling drilling hole in boring procedure, its Main Function increases resistance after bolt grouting and blocks anchor head effect.
To use at the bottom of airtight steel 3 airtight bottom drill bit 2, be equipped with rubber seal 5 between 3 and twist drill rods 7 at the bottom of airtight steel, prevent drill bit 2 and twist drill rods 7 from operationally causing damage because high-speed rotation produces friction.
Use sealing-plug 8 to seal with twist drill rods 7 aperture of central through hole 6 and sebific duct junction, prevent the junction of sebific duct and central through hole 6 from leaking gas, cause work to produce deviation.
Can with drilled as holes with reaming with expansion anchor pole hole-forming device from creeping into, the groove that reaming is formed has two aspect functions: one is the frictional resistance increased after slip casting between anchor bar body and rock-soil layer, improves anchorage effect; Two be groove as anchor pole head draw-in groove, can be fixing to expansion anchor head clamping.After this device Completion of Drilling Hole and reaming, be more convenient for anchor pole head and fix, make anchor pole total length stressed and increase frictional resistance, improve anchoring effect.
After the present invention switches on power, drill bit 2 fast rotational kata-rocks soil layer 1, broken cutting takes boring out of voluntarily by twist drill rods 7, high-pressure pump 11 is utilized in drill bit 2, to be filled with high pressure gas by central through hole 6, sharpener 4 stretches out drill bit 2, rotates expanded hole with drill bit 2, and after high pressure gas removal, sharpener 4 is regained by spring force, can complete with boring with expanded hole in boring procedure, increase resistance after reaming position is mainly used in bolt grouting and block anchor head effect.Simple to operate like this, flexibility is strong, is applicable to on-the-spot sharp work.
