Description
Technical field
The utility model belongs to the exploring equipment in the fields such as geological prospecting, tunnel piercing, engineering investigation, and in particular to one
The all-electric ultrasonic driller of kind.
Background technology
As social economy is fast-developing, the mankind need to carry out a large amount of in oil gas, resource exploration and infrastructure construction
Shallow layer drilling work, and efficiency crushing rock be always mineral resources probing, a problem of tunnel piercing, due to hard rock cause
It is close, intensity is high, abrasiveness is strong so that there are bit life is short, drilling efficiency low (being less than 1m/h), drilling cost are high for hard-rock boring
The problem of.
At present in (well) engineering is drilled, vibrating the method for detritus has single-impact (churn drilling, for water
Well, engineering well construction), (rotary-percussive drilling or rotating drilling, frequency are 12~16Hz to low frequency impact, geological prospecting, petroleum drilling
Well, the application of well engineering well), (also known as Sonic Drill, 70~150Hz of frequency, foreign countries are chiefly used in environmental geology to sonic impinging
Sample drilling is reconnoitred, domestic application is seldom).Single-impact, low frequency impact make rock produce broken cave, or coordinate again using impact
Rotary shear fractured rock is crept into, and rock strength reduces unobvious, and bit life, drilling efficiency are low;Sonic impinging (frequency
70~150Hz of rate) using vibration and the natural resonance frequency of drill string overlapping produce resonance, at this time drill string act like flywheel or
Spring handle energy is transmitted to drill bit, the cutting blade of drill bit is arranged material on its progress path in a manner of cutting, shear, be broken,
Cause grogs liquefaction around to allow drilling to become easy but loose crushing rock can only be crept into.At present people to low frequency (150Hz with
Under) vibrodrill carried out compared with in-depth study, research and development of the ultrasonic activation drilling machine suitable with the hard rock natural frequency of vibration or empty
In vain.Ultrasonic activation detritus (frequency>20000Hz) destroyed jointly using fatigue-resonance, i.e., the intrinsic frequency of complete fine and close hard rock
Generally 20KHz~40KHz, ultrasonic activation cause rock reasonably to be resonated, and periodic exciting force acts on rock
Cause inside quickly to crack, fracture suddenly occurs after crack propagation reaches a certain level, the intensity of rock can be significantly
Drastically decline, rate of penetration, bit life can increase substantially, the damage accumulation since regional area, finally cause overall broken
Bad process.Therefore research and development ultrasonic frequency vibrodrill, aids in detritus drilling to provide solution method, solves for ultrasonic activation
The technical barrier of hard-rock boring, fills the domestic gaps.
Foreign study current situation and development dynamic:
Sonic drilling technology is just studied early in 40~fifties of 20th century by the U.S. and the former Soviet Union.Former Soviet Union professor
D.D.Barkan has delivered the achievement in research on sonic drilling technology first, it is proposed that carries out sedimentary geology using acoustic vibration
Exploring drill hole.He proposes that sonic drilling is 3~20 times of traditional drilling method rate of penetration, develops a kind of ground vibration device
" VIRO-DRILLING " system, soil layer is crept into by effect of vibration.
The U.S. have developed a kind of bottom hole vibrator for being known as " sound brill ", it is therefore an objective to improves rate of penetration, and achieves a large amount of
The patent of dither drilling method, becomes the broken research of acoustic vibration revolution country the most active, successfully develops and be used for stone
High-power (5400Hp) sonic wave vibrator of oily drilling well and for petroleum gas seismic prospecting and gravel mine continuous sampling compared with
The sonic wave vibrator of small-power (100Hp), and obtain extraordinary effect.After the eighties, acoustic vibration drilling becomes environment and bores
The important means of spy simultaneously propagates to Canada.After the nineties, Japan has carried out acoustic vibration rotary drilling research, and this skill
Art introduces Asia environmental drilling.Canada, Holland carry out the research of acoustic vibration slewing drilling machine in succession, by acoustic vibration detritus skill
Art is combined with drilling machine, have developed a variety of sonic drills, is not rotated from initial bottom hole vibration or ground vibration and is developed into today
Ground vibration add rotation mode, and realize the specialization, standardization, seriation of vibration head, improve sonic drills can
By property and application range.Sonic drills vibration frequency is 50Hz~200Hz, a diameter of 100~300mm of ground sample.Sonic drill
Machine vibration swiveling head is hydraulic drive type, has sold to Chinese market.

The efficiency of drilling is higher, and the degree of automation of drilling machine is high, reduces the non-cutting time of drilling, alleviates the labor intensity of worker,
Meet the requirement of China's Urban Geological Survey drilling machine.It is but still relatively low for hard rock exciting force.
The second exploration administration of Chinese coal geology general bureau in 2011 and The Chinese Geology Univ. (Beijing) develop jointly out YSZ-50
Type sonic frequency resonance drill, power head drive two eccentric shafts, the eccentric inorganic tool connection of between centers, by respective using two high-speed motors
Reverse rotation at a high speed realize motor synchronizing, frequency reaches 150~200Hz, vibration force 140kN, oscillation power 39.2Kw.It is but dynamic
The serious service life of power hair heat is only capable of reaching 50h, it is necessary to the time for overhauling replacement is more so that operating efficiency reduce.
Ultrasonic activation detritus:Nanjing Aero-Space University's Huang in 2008 defends clear, Guo Junjie etc. and carries out piezoelectric vibration probing
Research, mainly for outer space drill sampling task, is developed for moon patrol car or the small-sized piezoelectric of special purpose robot ceramics
Vibrating drill trial and error test model machine, exciting force it is too small and only it is single consideration impact fatigue detritus, not formed specialization, seriation can not
Apply to Practical Project;Hangzhou Success Ultrasonic Equipment Co., Ltd applies the Series Ultrasonic vibrating device of piezoelectric ceramics development
(vibration frequency 15KHz~60KHz), is successfully applied to the cutting, welding and riveted of metal material, greatly reduces the weight of equipment
Amount, reduces power consumption, improves work efficiency;Shaoxing University Huang is German-Chinese only to be theorize that ultrasonic vibrator
On rock drill, the work efficiency of rock drill can be improved, reduces noise pollution, and above-mentioned ultrasonic activation detritus is theoretical single
One considers impact fatigue detritus, not with revolution impact fatigue-resonance detritus.
In conclusion ultrasonic wave Rock Technology is applied in core sampling, mining mineral resource and tunnel piercing both at home and abroad
Field still belongs to the exploratory stage.The vibration frequency that domestic sonic frequency resonance drill research and development are related to is low (being less than 150Hz), for ultrasonic wave
The research and development of vibration detritus drilling machine substantially belong to blank, and in recent years, (the precision and model of such as speed governing in terms of variable-frequency motor stepless speed regulation
Enclose, dynamic response characteristic and ease of use etc.) it is gradually improved, drilling machine develops towards safety, lighting and automation direction, and one
