Abstract

The invention discloses a cutter-suction device and a rock-breaking method based on ultrasonic-assisted rock breaking. The device comprises a cutter-suction dredger cutter-suction device, a connecting device and an ultrasonic auxiliary device. The cutter suction device of a cutter suction dredger includes a bridge frame, a tail shaft, an underwater pump, a suction pipe, a bridge frame pulley, a traverse pulley, an underwater motor, a reamer and a reamer shaft. The connecting device includes the upper cover, the plunger cylinder and the bracket. The ultrasonic auxiliary device includes an ultrasonic generator, an ultrasonic switch and an ultrasonic device. The present invention uses an ultrasonic auxiliary device to resonate the ultrasonic cutter head with the rock, allowing the rock to form gaps and cracks, destroying the integrity of the rock, reducing the strength of the rock, and correspondingly reducing the excavation resistance of the reamer. The knife and the ultrasonic device start to work simultaneously, which improves the excavation capacity and efficiency, reduces dredging energy consumption, and finally achieves the purpose of optimizing the cutter suction dredging reamer suction device and its use method.

Description

technical field

[0001] The invention relates to an ultrasonic-assisted rock breaking device and a rock breaking method, belonging to the technical field of dredging equipment. Background technique

[0002] With the rapid development of my country's shipping industry and the vigorous development of infrastructure projects such as ports and waterways, the domestic demand for dredging ships is increasing. Cutter suction dredger is one of the most commonly used dredging ships in dredging engineering. It has the characteristics of continuous operation, high production efficiency and low construction cost, but this feature is limited in rocky conditions. Due to the high strength of the rock and the increased resistance to excavation, the cutter suction device of the cutter suction dredger in the prior art has insufficient rock breaking ability, easy damage, high energy consumption, poor cutting effect on uneven rock and The existing method has problems such as low cutting efficie...
