Abstract
The utility model discloses a high -efficient detritus blade disc of TBM with ultrasonic vibrator, by ultrasonic vibrator, the biography pole that shakes, bearing structure, arbor and rock out machine disc cutter constitute, ultrasonic vibrator shakes pole and bearing structure through the biography to be fixed on rock out machine disc cutter's arbor, ultrasonic wave that ultrasonic vibrator produced shakes pole and bearing structure through the biography and transferes the arbor with high -frequency vibration, the arbor drives rock out machine disc cutter high frequency percussion rock in the cutting rock, the extension of rock crackle with higher speed, high -efficient detritus. The utility model discloses with the ultrasonic vibrator direct mount on the hobbing cutter pedestal of full section rock out machine TBM blade disc, form high frequency acoustic vibration and the joints detritus of gyration tunnelling, can effectively improve the detritus efficiency of TBM hobbing cutter, improve tunnelling speed, effectively reduce the wearing and tearing of TBM hobbing cutter, improve the working life of hobbing cutter, then effectively reduce construction cost.
Description
Technical field
This utility model relates to the efficient detritus cutterhead of a kind of TBM with ultrasonic vibrator. It is mainly used in the fields such as tunnel piercing, mining, City Underground Transportation construction. Specifically a kind of tunnel rock ripper cutterhead with ultrasonic vibrator and driving method thereof.
Background technology
Full face rock tunnel boring machine (FullFaceRockTunnelBoringMachine), is called for short TBM, is integrate large complicated underground construction equipment mechanical, electrical, light, liquid. It has quickly in tunnel excavating process, high-quality, safe and environment-friendly and economic dispatch advantage; construction is possible not only to improve speed of application; reduction of erection time; life can also be made to be respected; environment is effectively protected; therefore, tunnel piercing engineering has significantly high Social benefit and economic benefit.
But full face rock tunnel boring machine is in tunnel piercing, when particularly running into hard rock, hobboing cutter detritus speed is low, and the abrasion of hobboing cutter is very fast, has a strong impact on driving speed and the construction cost in tunnel. At present, TBM hob major part adopts imported product, expensive, and the wearability of domestic hobboing cutter is poor. Export full face rock tunnel boring machine construction work according to Qinling Tunnel practice have shown that, in tunnel excavating process, time used by the replacing of hobboing cutter, inspection and maintenance accounts for the 1/3 of the engineering time really, and expense accounts for the 1/3 of engineering construction cost, wherein because hob abrasion accounts for more than 80%.
Therefore, improve hobboing cutter detritus speed, improve cutter life, be TBM development machine technical problem urgently to be resolved hurrily.
The natural frequency of hard rock is 20KHz-40KHz, and when rock is subject to resonating, inside can quickly produce damage, and the intensity of rock can significantly decline. Different frequency, different voltage driving under, piezoelectric ceramic ultrasound vibrator can produce the mechanical vibration of frequency of vibration 15Hz-10GHz, vibration force 0-2000KN, can be used for the fractured rock that resonates. TBM development machine cutterhead is installed ultrasonic vibrator, is reduced the intensity of rock by ultrasonic activation, improve the detritus speed of hobboing cutter, improve cutter life.
Summary of the invention
The purpose of this utility model is in that the efficient detritus cutterhead of a kind of TBM with ultrasonic vibrator, this utility model is in rock ripper work process, by ultrasonic activation, makes rock interior crack, reduce the intensity of rock, improve the detritus efficiency of hobboing cutter; Reduce the abrasion of hobboing cutter, reduce construction cost.
This utility model is to be made up of ultrasonic vibrator, vibration-sensing rod, supporting construction, cutter shaft and Disc Cutters for TBM, ultrasonic vibrator is fixed on the cutter shaft of Disc Cutters for TBM by vibration-sensing rod and supporting construction, dither is passed to cutter shaft by vibration-sensing rod and supporting construction by the ultrasound wave that ultrasonic vibrator produces, cutter shaft drives Disc Cutters for TBM high-frequency percussion rock while rock cutting, accelerate the extension of rock crackle forming, efficient detritus.
Operation principle of the present utility model:
The dither that ultrasonic vibrator produces, is directly transmitted to Disc Cutters for TBM by cutter shaft. Disc Cutters for TBM is fractured rock under ultrasonic activation with revolution rock cutting synergy. Rock strength under Disc Cutters for TBM is first reduced by ultrasonic activation, again through revolution rock cutting.
The beneficial effects of the utility model:
1, the cutter shaft of ultrasonic vibrator Yu Disc Cutters for TBM is joined directly together by this utility model. The high frequency waves that such ultrasonic vibrator produces are either directly through Disc Cutters for TBM dither fractured rock, and the pressure of hobboing cutter, cutting force and high frequency vibrating power are applied simultaneously on rock to be broken, and penetration rate is good;
2, the frequency of vibration of ultrasonic vibrator of the present utility model is high, it is possible to reaches the resonant frequency of rock, makes rock interior quickly crack, and reduces rock strength, improves cutter life, improves driving speed.
3, this utility model is when equal detritus, it is possible to reduce the pressure being applied on disk cutter, effectively reduces the abrasion of disk cutter.
4, this utility model is under being applied to the pressure condition that Disc Cutters for TBM is big equally, it is possible to be effectively improved Rock penetrating speed, improves the working cycle of Disc Cutters for TBM, increases its use value, reduces construction cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Refer to shown in Fig. 1, the present embodiment is to be made up of ultrasonic vibrator 1, vibration-sensing rod 2, supporting construction 3, cutter shaft 4 and Disc Cutters for TBM 5, ultrasonic vibrator 1 is fixed on the cutter shaft 4 of Disc Cutters for TBM 5 by vibration-sensing rod 2 and supporting construction 3, dither is passed to cutter shaft 4 by vibration-sensing rod 2 and supporting construction 3 by the ultrasound wave that ultrasonic vibrator 1 produces, cutter shaft 4 drives Disc Cutters for TBM 5 high-frequency percussion rock 6 while rock cutting 6, accelerate the extension of rock 6 crackle, efficient detritus.
The operation principle of the present embodiment:
The dither that ultrasonic vibrator 1 produces, is directly transmitted to Disc Cutters for TBM 5 by cutter shaft 4. Disc Cutters for TBM 5 is fractured rock 6 under ultrasonic activation with revolution rock cutting synergy. Rock 6 intensity under Disc Cutters for TBM 5 is first reduced by ultrasonic activation, again through revolution rock cutting 6.
