Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of disc cutters, and particularly relates to a mud adhesion prevention shield disc cutter using ultrasonic vibration and a use method. BACKGROUND

[0002] In recent years, with the implementation of the national strategy of building a powerful country in transportation, cross-regional channel projects have been successively started and constructed, and the cross-river sea tunnel is the main form of the cross-regional channel. The cross-river sea tunnel has the characteristics of high water pressure, large section, and long distance in the construction process. Generally, a slurry shield is used for tunneling construction. In order to deal with the rock stratum encountered on the shield tunneling line, a certain number of disc cutters are often equipped on the shield cutter head to crush the rock with high strength. However, in the process of shield tunneling, the stratum distribution is variable, and as the shield excavation diameter continuously increases, the cutter head excavation section encounters multiple strata, i.e., composite strata. When the content of the adhesive mineral in the stratum is high, the disc cutter ring is easy to adhere to the adhesive particles in the stratum, and then gradually block the pores between the cutter barrel or cutter and the cutter head panel, so that the disc cutter cannot rotate, causing disc cutter damage. The key to solving the above engineering problems lies in reducing the adhesion between the disc cutter and the adhesive particles in the stratum.

[0003] The existing methods for reducing adhesion of shield equipment mainly include surface coating, electro-osmotic adhesion reduction, bionic interface, and injection of adhesion reduction agent. However, the above methods have limitations: (1) the surface coating treatment and bionic interface on the surface of the shield cutter head and cutter can effectively reduce the adhesion between the adhesive mineral and the metal surface, but the surface coating and bionic structure are easy to be worn out as the shield cutter head and cutter cut the stratum, losing the adhesion reduction effect; (2) the electro-osmosis can increase the thickness of the water film between the adhesive soil and the metal contact interface, reducing the adhesion of the adhesive soil to the shield cutter head and cutter, but the electro-osmosis will cause a large amount of mud at the mud shield excavation surface to be electrolyzed, generating hydrogen and oxygen, which is not conducive to engineering safety, and the metal at the electrode is easy to be subjected to electrochemical corrosion; (3) various adhesion reduction agents have been tried in engineering to reduce the adhesion of the adhesive soil, but the adhesion reduction agent has complex composition and large engineering dosage, and the harmful substances in the adhesion reduction agent penetrate into the soil around the tunnel and continuously accumulate in the soil, causing irreversible damage to the ecological environment.

[0004] In recent years, the use of ultrasonic vibration to achieve friction reduction and viscosity reduction in mechanical and other fields has been widely applied. Yang Zhigang et al. used piezoelectric vibrator to generate ultrasonic vibration to prove that the friction coefficient in the vibration state is significantly reduced, and analyzed the friction reduction mechanism of ultrasonic vibration. Zhang Chen et al. applied ultrasonic vibration to ball screw pair, and carried out finite element analysis on the friction reduction vibrator and made a sample for experiment. The experimental results show that ultrasonic vibration has good friction reduction property. Xu Xi-qiang et al. applied ultrasonic vibration to oil sand asphalt pipeline transportation, and the experiment proved that ultrasonic vibration has good viscosity reduction effect on oil sand asphalt, and the results show that the viscosity reduction rate reaches more than 80%. Dai Zheming et al. added axial ultrasonic vibration generated by piezoelectric ceramic on the extrusion screw cutter shaft of ceramic pug mill to realize the effect of viscosity reduction and drag reduction in the extrusion process of pug mill.

7. The anti-adhesion slurry shield cutter using ultrasonic vibration according to claim 2, characterized in that: The outer wall of the movable plate (315) fits with the inner wall of the movable groove (310), the outer wall of the insertion rod (316) fits with the inner walls of both the first insertion hole (313) and the second insertion hole (314), and the outer wall of the baffle (318) is provided with a wire hole (8).

8. The anti-adhesion slurry shield cutter using ultrasonic vibration according to claim 3, characterized in that: The fixing frame (405) is C-shaped, and a through slot for the displacement frame (407) to slide is provided on the outer wall of the fixing frame (405), and the pushing block (409) is in contact with the inner wall of the inclined slot (410).

9. The anti-adhesion slurry shield cutter using ultrasonic vibration according to claim 3, characterized in that: The outer wall of the connecting rod (401) fits in contact with the inner wall of the connecting groove (404), and the outer wall of one end of the fixing frame (405) fits in contact with the inner wall of the fixing groove (402).

10. A method for using an anti-adhesion slurry shield cutter using ultrasonic vibration, characterized in that: The specific steps are as follows: Step 1: Rotate and install the knife ring (1) on the outer wall of the knife shaft (301), and insert the square rod (305) into the inner wall of the knife shaft (301); Step 2: Pass the square rod (305) through the first square slot (309) and the second square slot (312), then rotate the rotating disk (311), and the rotating disk (311) rotates into the card slot (306) to fix the square rod (305), and at the same time aligns the first socket (313) with the second socket (314), connects the movable plate (315) into the movable slot (310), and inserts the rod (316) through the first socket (313) and the second socket (314) into the circular slot (308), and one end of the rod (316) contacts the outer wall of the knife shaft (301); Step 3: Install the ultrasonic vibration exciter (317) into the movable groove (310), and close the movable groove (310) through the baffle (318); Step 4: The power box is connected to the ultrasonic vibration exciter (317) through a wire.
