TBM cutter head suitable for flexible arm heading machine and excavation method thereof

Abstract

The invention discloses a TBM cutter head suitable for a flexible arm heading machine and an excavation method thereof. The TBM cutter head and the excavation method of the TBM cutter head suitable for the flexible arm heading machine solve the problem of low excavation efficiency of the TBM cutter head matched the flexible arm heading machine in the prior art. The TBM cutter head comprises a fixed cutter cylinder, wherein the fixed cutter cylinder is connected with a main drive through a parallel oil cylinder mechanism, a main excavation cutter is arranged on the front panel of the fixed cutter cylinder, and a side rotary excavating cutter is arranged on the outer ring surface of the fixed cutter cylinder. According to the TBM cutter head suitable for the flexible arm heading machine andthe excavation method thereof, the outer wall of the fixed cutter cylinder is provided with a side hobbing cutter set in the axial direction, the side hobbing cutter set cooperates with the main excavation cutter to extrude rock breaking and rotary cutting rock breaking on the tunnel face and the hole wall, and the excavation efficiency of the flexible arm heading machine is improved. In addition,the cutter head can rotate relative to the parallel oil cylinder mechanism, a traditional extrusion rock breaking is converted into rotary pressure rock breaking, and the two working modes can be arbitrarily switched so as to meet the requirements of different working conditions and improve the applicability of the device.

Description

technical field [0001] The invention relates to the technical field of shield machines, in particular to a TBM cutter head suitable for a flexible boom boring machine and an excavation method thereof. Background technique [0002] The current full-face roadheader cutter head is mainly composed of positive hobs, side hobs, and scrapers. The ability of rock must also have the ability of rotary cutting and breaking rock. When rotary cutting and breaking rock, the front of the cutter head is parallel to the face of the face or has a small inclination angle with the face of the face. The force of the tool on the side of the cutter head is mainly used to break the rock. , the force direction of the cutter head changed from axial force to radial force. However, the current cutter head mainly relies on the cutters on the front panel to squeeze and break the rock, and there are few side hobs on the side, and the arrangement position of the hobs on the side of the cutter head does no...
