Abstract

The invention discloses a rectangular shield cutter head device and a synchronous control method of the rectangular shield cutter head device. The cutter head device comprises a first cutter head, a second cutter head, an eccentric multi-axis special-shaped cutter head, a first cutter head driver, a second cutter head driver and an eccentric multi-axis special-shaped cutter head driver, wherein the first cutter head and the second cutter head are arranged on a front section shell at a set angle difference, the eccentric multi-axis special-shaped cutter head is located behind the first cutter head and the second cutter head, the first cutter head driver is used for driving the first cutter head to conduct circular motion, the second cutter head driver is used for driving the second cutter head to conduct circular motion, and the eccentric multi-axis special-shaped cutter head driver is used for driving the eccentric multi-axis special-shaped cutter head to conduct eccentric rotational motion. The first cutter head and the second cutter head are X-shaped spoke type structure cutter heads, the set angle difference ranges from 80 degrees to 100 degrees, and the center distance of the first cutter head and the second cutter head is smaller than the sum of the radius of the first cutter head and the radius of the second cutter head. The first cutter head and the second cutter head do not collide with each other and conduct excavation on a first work face, the eccentric multi-axis special-shaped cutter head conducts cutting on a second work face, the whole cutter head device conducts cutting in a rectangular section at the maximum area, the whole excavation face is made to be rectangular, and full section cutting is achieved.

Description

technical field [0001] The invention relates to the field of tunnel shield technology, in particular to a rectangular shield cutter head device and a synchronous control method thereof. Background technique [0002] With the sustained and steady growth of our country's economy and the further acceleration of the urbanization process, the demand for underground tunnels in our country is also increasing year by year. Coupled with the enhancement of people's awareness of environmental protection, rectangular shield technology will play an increasingly important position and role in the construction of underground pipelines in our country. The development of trenchless technology is bound to develop in the direction of scale, standardization and internationalization. [0003] However, the development of the rectangular shield technology also faces many challenges, among which the control method of the cutting cutter is one of the important challenges. The usual cutter head con...
