Problems solved by technology

[0003] However, when the full-face rock boring machine is tunneling, especially when it encounters hard rock, the rock-breaking speed of the hob is low, and the wear of the hob is fast, which seriously affects the tunneling speed and construction cost.
At present, most TBM hobs are imported products, which are expensive, while domestic hobs have poor wear resistance

Embodiment Construction

[0016] see figure 1 As shown, the present embodiment is composed of an ultrasonic vibrator 1, a vibrating rod 2, a support structure 3, a cutter shaft 4 and a disc-shaped hob 5 of a rock excavator, and the ultrasonic vibrator 1 is fixed by the vibrating rod 2 and the supporting structure 3 On the cutter shaft 4 of the disc-shaped hob 5 of the rock excavator, the ultrasonic wave generated by the ultrasonic vibrator 1 transmits the high-frequency vibration to the cutter shaft 4 through the vibrating rod 2 and the support structure 3, and the cutter shaft 4 drives the disc-shaped hob of the rock excavator. The hob 5 impacts the rock 6 at high frequency while cutting the rock 6, so as to accelerate the expansion of cracks in the rock 6 and effectively break the rock.

[0017] The working principle of this embodiment:

[0018] The high-frequency vibration generated by the ultrasonic vibrator 1 is directly transmitted to the disc hob 5 of the rock boring machine through the cutter ...

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 [0001] The invention relates to a TBM high-efficiency rock-breaking cutter head with an ultrasonic vibrator. It is mainly used in tunneling, mining, urban underground transportation construction and other fields. Specifically, the utility model relates to a tunnel rock boring machine cutter head with an ultrasonic vibrator and a tunneling method thereof. Background technique [0002] Full Face Rock Tunnel Boring Machine (TBM for short), is a large complex underground construction equipment integrating machine, electricity, light and liquid. It has the advantages of speed, high quality, safety, environmental protection and economy in the process of tunnel excavation. It can not only increase the construction speed and shorten the construction period during construction, but also respect life and effectively protect the environment. Therefore, in tunnel excavation engineering It has high social and economic benefits. [0003] However, when the full-face rock...
