Abstract

The invention relates to the technical field of vertical shaft excavating and tunneling equipment, in particular to a full-section telescopic cutter head structure for a vertical shaft tunneling machine. The full-section telescopic cutter head structure comprises a cutter head body, swing arms and a power unit, and cutters are arranged on the lower parts of the cutter head body and the swing arm correspondingly and used for drilling of the tunneling machine; the multiple swing arms are arranged on the periphery of the cutter head body, each swing arm is connected with the power unit through acorresponding connecting rod mechanism, and the connecting rod mechanisms are driven by the power unit to rotate, so that the swing arms can make telescopic movement on the periphery of the cutter head body; and a sensor is arranged at the power output end of the power unit and used for sensing movement of the power unit, so that the multiple swing arms on the periphery of the cutter head body move synchronously. The cutter head body and the swing arms form the integral full-section cutter head structure, the swing arms are connected with the cutter head body through the connecting rod mechanisms, the other ends of the connecting rod mechanisms are connected with the power unit, the power unit stretches out and draws back to drive the swing arms to act, and the scalability of a cutter headis achieved; and the rock breaking efficiency is high, and the well completion offset is small.

Description

technical field [0001] The invention relates to the technical field of shaft excavation and excavation equipment, in particular to a full-section retractable cutterhead structure of a shaft excavation machine. Background technique [0002] Shaft boring machine is drilling equipment. Drilling is a drilling process in which a shaft drilling rig mechanically breaks rocks at the designed wellbore position to drill a wellbore whose depth and diameter meet the requirements, and performs permanent support to form the wellbore. It consists of rock-breaking drilling, circulating slag discharge, mud wall protection, well wall making, and backfilling. Among them, the cutterhead structure of the shaft boring machine plays the role of rock-breaking drilling. [0003] Most of the existing shaft boring machine cutter head structures are part-section cutter head structures, that is, the diameter of the cutter head is smaller than the excavation diameter of the wellbore. Big. Since the s...
