The specific embodiment:
Be described in further detail below in conjunction with drawings and Examples:
The main shaft transfer torque also is subjected to the axial vibration impact force, makes boring be subjected to the effect of composite force at the bottom of the hole, can improve drilling efficiency greatly in the construction.Can realize in the work of the utility model gyrator that following three kinds of functions work i.e. rotary drilling to adapt under the Different Strata; Vibro-drilling; Vibration rotary drilling.
Be provided with two above vibration components 2 in the vibrating bin 1, vibrating bin 1 underrun bolt connects vibrating hammer 3, vibrating hammer 3 cooperates with main shaft 10 vibrations, the both sides of vibrating bin 1 are provided with and connect picking up the ears of two-way shock-absorbing spring 5, the lower end of two-way shock-absorbing spring 5 is fixed on the junction plate 4 that gear-box 7 tops are provided with, place main shaft 10 stage casings of gear-box 7 gear wheel 9 to be housed by key pin, gear wheel 9 bilateral symmetry are equipped with pinion 8, gear wheel 9 designs at grade with pinion 8, and be connected, gear-box 7 tops symmetry main shaft 10 is equipped with hydraulic motor 6, and pinion 8 is contained on the turning cylinder of hydraulic motor 6 by key pin.Vibration component 2 is that eccentric block 12 and gear 11 formations are housed on the turning cylinder of hydraulic motor 13.
Slewing equipment is made up of two parts, and top is the vibration action assembly, and the lower part is the revolution action component.In gyro black assembly, drive pinion 8 by two hydraulic motors 6, gear wheel 9 is given in transmission, drives main shaft 10 revolutions by spline, thereby realizes the rotary drilling function.
Oscillating component drives two axles that eccentric block is housed by the biliquid pressure motor, makes it to produce vibration force, is provided with a pair of gear at axle one end, reaches synchronous rotating purpose by meshed transmission gear.Oscillating component is equipped with vibrating hammer and directly contacts with main shaft, when oscillating component vibrates, by vibrating hammer vibration force is passed to main shaft, passes to drilling tool work downwards by main shaft.Not to oscillating component hydraulic motor fuel feeding,, realize rotary drilling to rotating part hydraulic motor fuel feeding; Not to rotating part hydraulic motor fuel feeding,, realize vibro-drilling, vibration frequency 60Hz to oscillating component hydraulic motor fuel feeding.To rotating part and oscillating component hydraulic motor fuel feeding, realize vibration, compound the creeping into of revolution simultaneously.
When the sand of drilling tool front portion was subjected to vibrating, the soil layer particle was kept in motion, and under the inertia force effect, sand has density trend, and the water of soil layer has little time to discharge at short notice, and the hole is pressed and will be risen, and the soil layer effective stress is reduced.When effective stress drops to zero, just no longer transmit stress (comprising gravity) between the soil layer particle, soil layer completely loses shear strength and supporting capacity, and this moment, the soil layer particle was in flow regime, and just " liquefaction " has taken place in the stratum.When the drilling tool front portion is viscous soil horizon, cohesive soil is under the effect of strong perturbed forces such as vibration, stress direction in the soil layer changes repeatedly, the instantaneous decline of effective stress that makes soil layer is pressed in the pulsation hole in each circulation, the instantaneous reduction of shear strength, thereby the limit equilibrium district in the stratum is periodically enlarged, produce the accumulation plastic strain, promptly so-called " thixotroping " effect.Vibratory impulse revolution boring has utilized this " liquefaction " of soil layer and the purpose that " thixotroping " character reaches the high speed pore-forming just.
