The multifunctional high-frequency resonant coring bit has the main advantages as follows: high-frequency resonant anhydrous dust-control rapid coring of a soft rock sample can be realized, rapid coring with the soft rock sample softening inhibition under anhydrous, dust-control and geological fluid conditions and other different conditions on the same equipment is realized, and the multifunctional high-frequency resonant coring bit has very important scientific significance and a practical application value on the aspects of improving soft rock maintenance and experiment efficiency, reducing the experimental cost, shortening experimental time and expanding the related experimental content and scale.
Description
Technical field
The invention belongs to Geotechnical Engineering test apparatus field, particularly the soft rock coring bit that resonates of a kind of multifunctional high frequency, be applicable to the fast fetching core under the conditions such as anhydrous, dustless in soft rock sample making process, geology pendular ring border.
Background technology
It is one of the advanced subject in international project geology department field that soft rock meets water softening.Its softening test research is Focal point and difficult point wherein, is the basis of many Important Project catastrophe Mechanism Study and control, has become the focus that academia and engineering circles are paid close attention to jointly.At present, in the mechanics effect and model thereof of its softening mechanism, deformation failure, carry out more work by experiment, begin to take shape the fundamental test framework that soft rock softens research.Wherein, the indoor of soft rock sample are got core, cut sample preparation etc. is that premise is carried out in test, and all needs to cause sample softening destruction gradually with water for cooling, is difficult to maintain intensity.Particularly, it is slow that core process is got in the rotation of soft rock sample or impact, palpus water cools drill bit, depositing dust, and water consumption is large, soft rock sample is made often to be in moist water state and then softening destruction, cause the success ratio of getting core and cutting sample preparation greatly to reduce, particularly the low success rate of argillaceous soft rock sample preparation is more outstanding, becomes the bottleneck problem of soft rock test.But, there is not yet reasonable effective method for this problem at present, greatly reduce soft rock test efficiency, add maintenance difficulty, improve experimentation cost, extend test period, seriously constrain carrying out of soft rock test.Therefore, can the principle of fast cutting material according to high-frequency resonance, the soft rock coring bit of a kind of multifunctional high frequency resonance of development and design, emphasis for soft rock sample get core process slowly, chilled water is to sample broke problem, take into account and efficiently control dirt, solve the problem that core equipment shortcoming efficiently got by soft rock sample, for promoting soft rock maintenance and test efficiency, reducing experimentation cost, shortening test period and expand correlation test content and scale etc., there is very important scientific meaning and actual application value.
Summary of the invention
Order of the present invention is, efficiently gets the problem of core equipment shortcoming for existing soft rock sample, provide a kind of can the equipment of fast fetching core under the condition such as anhydrous, dustless in soft rock sample making process, geology pendular ring border.
The soft rock coring bit of a kind of multifunctional high frequency resonance that the present invention relates to, is made up of dither drill bit, dither controller, geology fluid controller.
1, dither drill bit
Dither drill bit by dither head, vibration head axis, vibration transmission interface, vibration head snap close, drilling rod, cooling control dust hood position bayonet socket, cooling control dust hood, the import of geology liquid, geology liquid spout, cut that rotary drill is first-class to be formed, utilize high-frequency resonance can the principle of fast cutting material, realize the resonance of dither drill bit and soft rock sample, to cut, to shear, the control dirt fast fetching core of the mode such as rotation; And make temperature of diamond bit sharply to raise fast owing to getting core and without the need to water cooling, can prevent soft rock sample from softening destruction because of wet water.
2, dither controller
Dither controller is made up of vibration engine, vibration transmission shaft etc., can realize exporting dither to drill bit according to the natural frequency of soft rock sample, thus causes the resonance of soft rock sample, realizes fast fetching core.
3, geology fluid controller
Geology fluid controller is made up of geology liquid driving pump, geology fluid catheter, geology liquid etc., can realize simulation and the applying of soft rock sample geology liquid; Suppress soft rock to soften principle according to geology liquid, long-time extensive soft rock sample can be realized and get drill bit cooling under core condition and soft rock can be suppressed to meet water softening.
The present invention has the following advantages:
1, can realize the high-frequency resonance of soft rock sample without water control dirt fast fetching core.
2, the fast fetching core suppressing soft rock sample softening anhydrous, the control different condition such as dirt, geology liquid can be realized on same equipment under.
3, this bit gravity is light, stability is high, efficiency is high, structure is simple, it is convenient, easy to operate to clean, and does not have very strong technical requirement to experimental test personnel.
Accompanying drawing explanation
Fig. 1 is entirety composition structural representation of the present invention.
Wherein:
A. dither drill bit: A1. dither head; A2. vibration head axis; A3. transmission interface is vibrated; A4. vibration head snap close; A5. drilling rod; A6. cooling control dust hood position bayonet socket; A7. cooling control dust hood; A8. geology liquid import; A9. geology liquid spout; A10. rotary drill head is cut.
B. dither controller: B1. vibration engine; B2. vibration transmission shaft.

Fig. 2 specifically gets core embodiment process flow diagram.
Embodiment
Below in conjunction with accompanying drawing, technical scheme of the present invention is further illustrated:
A. dither drill bit is connected B. dither controller and C. geology fluid controller, forms the soft rock coring bit of complete multifunctional high frequency resonance.Get in core process, first, A. dither drill bit is fixed on corning machine by A2. vibration head axis; Soft rock sample to be positioned over below A. dither drill bit then, is regulated and fix A7. to cool the position controlling dust hood by A6. cooling control dust hood position bayonet socket, effectively to control dirt, cuts rotary drill head need cool moment effective cooling A10.; Then, according to the natural frequency of soft rock sample, open B. dither controller, regulate vibration frequency, and by B2. vibration transmission shaft, A1. dither head is passed in vibration; A1. vibration is passed to A10. by A4. vibration head snap close and A5. drilling rod and is cut rotary drill head by dither head, realizes the resonance with soft rock sample; Cut rotary drill head finally by A10. and realize control dirt fast fetching core.Simultaneously, if cause A10. to cut rotary drill head because core got by long-time extensive soft rock sample need cooling, then open C. geology fluid controller, the inner loop pipeline and A9. geology liquid spout thereof of controlling dust hood is cooled by C2. geology fluid catheter and A7., A10. will be sprayed onto cut rotary drill head by soaked or other salt solusion configuration C3. geology liquid by similar soft rock, realize A10. cut the cooling of rotary drill head and control dirt further, and suppress soft rock to soften principle according to geology liquid, the softening destruction of soft rock sample can be suppressed.
