Abstract
The invention discloses a TBM (Tunnel Boring Machine) high-efficient rock-crushing cutter head with an ultrasonic vibrator. The TBM high-efficient rock-crushing cutter head comprises the ultrasonic vibrator, a vibration transmitting rod, a supporting structure, a cutter shaft and a rock TBM disc cutter, wherein the ultrasonic vibrator is fixed on the cutter shaft of the rock TBM disc cutter through the vibration transmitting rod and the supporting structure; high-frequency vibration is transmitted to the cutter shaft through the vibration transmitting rod and the supporting structure due to ultrasonic wave generated by the ultrasonic vibrator; the cutter shaft drives the rock TBM disc cutter to cut rock and impact the rock at a high frequency simultaneously, so that the extension of rock cracks is accelerated, and the rock is crushed efficiently. The TBM high-efficient rock-crushing cutter head with the ultrasonic vibrator has the advantages that the ultrasonic vibrator is directly arranged on a cutter shaft frame of a full fracture face rock TBM cutter disc, so that high-frequency sound wave vibration and gyration are combined for rock crushing and tunneling, therefore the rock crushing efficiency of the TBM cutter can be effectively improved, the tunneling speed is increased, the abrasion of the TBM cutter is effectively reduced, the service life of the cutter is prolonged, and the construction cost is effectively lowered.
Description
Technical field
The present invention relates to the efficient detritus cutterhead of a kind of TBM with ultrasonic vibrator.Be 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), be called for short TBM, be integrate mechanical, electrical, the large complicated underground construction equipment of light, liquid.It has fast in tunnel excavating process, high-quality, safety, environmental protection and economic dispatch advantage; not only speed of application can be improved in construction; reduction of erection time; life can also be made to be respected; environment is effectively protected; therefore, in tunnel piercing engineering, there is very 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 wearing and tearing of hobboing cutter are very fast, have a strong impact on driving speed and the construction cost in tunnel.At present, TBM hob major part adopts imported product, expensive, and the abrasion resistance of domestic hobboing cutter is poor.Show according to the practice of Qinling Tunnel outlet full face rock tunnel boring machine construction works, in tunnel excavating process, the time used due to the replacing of hobboing cutter, inspection and maintenance accounts for 1/3 of the engineering time really, and expense accounts for 1/3 of engineering construction cost, wherein because hob abrasion accounts for more than 80%.
Therefore, improving hobboing cutter detritus speed, improve cutter life, is TBM development machine technical problem urgently to be resolved hurrily.。
The intrinsic frequency of hard rock is 20KHz-40KHz, and when rock is subject to resonating, inside can produce damage fast, and the intensity of rock can significantly decline.Under the driving of different frequency, different voltage, piezoelectric ceramic ultrasound vibrator can produce vibration frequency 15Hz-10GHz, the mechanical oscillation of vibration force 0-2000KN, can be used for the fractured rock that resonates.Ultrasonic vibrator installed by TBM development machine cutterhead, is reduced the intensity of rock by ultrasonic wave vibration, improve the detritus speed of hobboing cutter, improve cutter life.
Summary of the invention
The object of the invention is to the efficient detritus cutterhead of a kind of TBM with ultrasonic vibrator, the present invention, in the rock ripper course of work, is vibrated by ultrasonic wave, and rock interior is cracked, and reduces the intensity of rock, improves the detritus efficiency of hobboing cutter; Reduce the wearing and tearing of hobboing cutter, reduce construction cost.
The present invention is made up of ultrasonic vibrator, vibration-sensing rod, braced structures, 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 braced structures, dither is passed to cutter shaft by vibration-sensing rod and braced structures by the ultrasonic wave that ultrasonic vibrator produces, cutter shaft drives Disc Cutters for TBM high-frequency percussion rock while rock cutting, accelerate the expansion of rock crackle forming, efficient detritus.
Operating principle of the present invention:
The dither that ultrasonic vibrator produces, directly passes to Disc Cutters for TBM by cutter shaft.Disc Cutters for TBM is fractured rock under ultrasonic wave vibration with the synergy of revolution rock cutting.Rock strength under Disc Cutters for TBM first reduces by ultrasonic wave vibration, then by revolution rock cutting.
Beneficial effect of the present invention:
1, ultrasonic vibrator is directly connected with the cutter shaft of Disc Cutters for TBM by the present invention.The high frequency waves that such ultrasonic vibrator produces are directly by Disc Cutters for TBM dither fractured rock, and the pressure of hobboing cutter, cutting force and high frequency vibrating power are applied on rock to be broken simultaneously, and penetration rate is good;
2, the vibration frequency of ultrasonic vibrator of the present invention is high, can reach the resonance frequency of rock, and rock interior is cracked fast, reduces rock strength, improves cutter life, improves driving speed.
3, the present invention is when equal detritus, can reduce the pressure be applied on disk cutter, effectively reduces the wearing and tearing of disk cutter.
4, the present invention is being applied under Disc Cutters for TBM pressure condition large equally, can effectively improve Rock penetrating speed, improves the work period of Disc Cutters for TBM, increases its use value, reduces construction cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Refer to shown in Fig. 1, the present embodiment is made up of ultrasonic vibrator 1, vibration-sensing rod 2, braced structures 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 braced structures 3, dither is passed to cutter shaft 4 by vibration-sensing rod 2 and braced structures 3 by the ultrasonic 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 expansion of rock 6 crackle, efficient detritus.
The operating principle of the present embodiment:
The dither that ultrasonic vibrator 1 produces, directly passes to Disc Cutters for TBM 5 by cutter shaft 4.Disc Cutters for TBM 5 is fractured rock 6 under ultrasonic wave vibration with the synergy of revolution rock cutting.Rock 6 intensity under Disc Cutters for TBM 5 first reduces by ultrasonic wave vibration, then by revolution rock cutting 6.
