Abstract

The invention discloses a hydraulic cutting tool module. The hydraulic cutting tool module comprises a hydraulic cutting tool module frame, a thrust spring structure, a hydraulic cutting tool module thrust oil cylinder and a hydraulic cutting hob for combined rock breaking, wherein the thrust spring structure is located in the hydraulic cutting tool module frame, the hydraulic cutting tool modulethrust oil cylinder is located at the upper end of the thrust spring structure, and the hydraulic cutting hob for combined rock breaking is fixed to the lower end of the hydraulic cutting tool moduleframe and is of a spoke structure. The hydraulic cutting tool module has the advantages that the weight of the hob is reduced through lightweight treatment, and the rock breaking efficiency is improved. The invention further discloses a hydraulic-mechanical combined rock breaking TBM device. The invention further discloses a rock breaking method of the hydraulic-mechanical combined rock breaking TBM device.
