Abstract

The invention provides a cutterhead supporting device. A plurality of cutterhead supporting units are arranged inside a heading machine to bear the rock-soil pressure. In this way, the additional bending moment applied on a cutterhead is reduced, and the expense in purchasing large bearings is reduced. Meanwhile, the device is convenient to install, repair and replace.

Description

technical field [0001] The invention relates to a cutter head supporting device, which is suitable for the design and manufacture of a boring machine. Background technique [0002] Existing roadheaders are all provided with a cutterhead conforming to the diameter of the built tunnel, and on the cutterhead surface facing the shaft surface on the cutterhead, several fixed or freely rotating cutters are housed. Immediately behind the cutter head, there is a cylinder as the casing of the roadheader. In the center of the cylinder, a shaft that can rotate around the tunnel axis is supported by bearings. The front end of the rotating shaft is connected with the cutterhead, and the rear part is connected with the gear and the motor. The power of the motor drives the rotating shaft through the gear, drives the cutter head to rotate, and then cuts the rock and soil through the cutter on the cutter head. [0003] The tunnel boring machine designed with this method has the cover type ...
