Abstract

The invention discloses a deep shaft rock tunnel boring machine. The machine comprises a derrick arranged on the ground and an underground device platform, wherein a first-stage slag transfer system,a second-stage tunnel boring system, a second-stage slag discharge system, a first-stage slag discharge system and a first-stage tunnel boring system are sequentially arranged below the device platform, the first-stage tunnel boring system is used for expanding the depth of the shaft, the second-stage tunnel boring system is used for expanding the width of the shaft, the first-stage slag dischargesystem conveys the rock slag generated by the excavation of the first-stage tunnel boring system to the first-stage slag transfer system, the second-stage slag discharge system conveys the rock slaggenerated by the excavation of the second-stage tunnel boring system to the first-stage slag transfer system, and the first-stage slag transfer system is used for discharging the rock slag. By arranging the synchronous work of the second-stage tunnel boring system, the depth and the width of the shaft are simultaneously expanded, the hierarchical excavation effectively increases the excavation depth; and by arranging the slag discharge system and the slag transfer system, the slag discharge operation can be completed in the excavation process, so that the automation degree and the working efficiency are further improved.

Description

Technical field [0001] The invention relates to the field of engineering machinery, in particular to a deep shaft rock boring machine. Background technique [0002] Shaft excavation is required in various projects. Existing shaft excavation methods have experienced long-term development. The main sinking methods include drilling and blasting and drilling methods. Shaft excavation equipment has also experienced the same development process, but no major breakthrough has been achieved. The existing shaft boring machine is generally provided with only one boring system at the bottom to achieve depth and width expansion. However, this kind of equipment is difficult to automate, with numerous procedures, cumbersome construction, low sinking efficiency, high manual labor intensity, and most importantly, the limited excavation depth makes it difficult to realize deep shaft construction. [0003] Therefore, how to provide a deep shaft rock boring machine with a high degree of automation a...
