Vertical shaft shield tunneling machine

Abstract

The invention discloses a vertical shaft shield tunneling machine. A cutter head driving system is arranged in a shield body of the vertical shaft shield tunneling machine; the rotation output end of the cutter head driving system is fixedly provided with a connection barrel extending to the front end; the front end of the connection barrel is fixedly provided with a cutter head with a closed cavity inside; the connection barrel is rotationally supported on the shield body by a main bearing; a stirring device is arranged in the cavity of the cutter head; a cutter is arranged on the outer surface of the cutter head; a slag inlet for communicating the cavity of the cutter head and the outside is reserved on the cutter head; a girder is arranged in the shield body; a slurry input pipeline and a slagging pipeline are arranged in the girder; the front end of the slurry input pipeline extends to the front end face of the cutter head; the rear end part of the cutter head is provided with the slagging pipeline communicated with the cavity of the cutter head; the rear end of the slagging pipeline extends out of the girder; the rear end of the shield body is provided with a propelling system; a thrust oil cylinder of the propelling system is used for being pressed against a duct piece assembled by a duct piece splicing machine. According to the invention, full- face integral forming of a vertical shaft can be implemented and the tunneling speed of the vertical shaft is greatly improved.

Description

technical field [0001] The invention relates to a mechanical device for shaft operations, in particular to a shaft shield machine. Background technique [0002] When excavating underground mineral deposits, it is necessary to form shafts in the excavated strata. With the development of the national economy, there is an increasing demand for underground mineral deposits. The mining of underground mineral deposits has also changed from open-pit mining to underground mining, and the construction of shafts is also rapidly increase, but the shaft digging device does not improve along with the growth of the shaft construction project, and the shaft digging device in the prior art is still relatively backward. The current shafts are generally excavated manually from top to bottom. When a certain depth is reached, the walls are built from the bottom up. The excavation and wall building are carried out alternately. Sometimes it is necessary to spray grout on the well wall before ...
