Embodiment Construction

[0016] like figure 1 , figure 2 As shown in the figure, the present invention is composed of a spoke type cutter head 1, a panel type box cutter head group 2 and a bolt 3. The spoke type cutter head 1 and the panel type box cutter head group 2 are independent components respectively, and the cutter head panel is in the form of spokes. When the cutter head is a type of cutter head, the cutter head panel adopts the spoke type cutter head 1; or when the cutter head panel is a panel type, the panel type box cutter head group 2 is connected to the large box body seat 11 and the spoke type cutter head by bolts 3. The panel-type cutter head 4 is formed on the small box base 12 . The aperture ratio of the cutter head can be changed by selecting different sizes of the panel box cutter head group 2 .

[0017] like image 3 , Figure 4 As shown, the spoked cutter head 1 is composed of a disc outer ring 5, four spoke-shaped spokes 6, a ring rib 7, a front panel 8, a rear panel 9, a c...

Abstract

The present invention relates to a cutting cutterhead of variable cutterhead type driving machine, belonging to the field of tunnel machery technology. It is formed from spoke type cutterhead, panel type box body cutterhead groups and bolts, in which the spoke type cutterhead and panel type box body cutterhead group are independent member respectively. Besides, said invention also provides their application method.

Description

technical field [0001] The invention relates to a cutting cutter head for tunnel excavation, in particular to a cutting cutter head of a spoke-type and panel-type interchangeable changeable cutter head type boring machine for tunnel excavation under different soil conditions. It belongs to the technical field of tunnel machinery. Background technique [0002] According to the geological conditions and construction control requirements, the cutter head of the tunnel boring machine can be roughly divided into panel type and spoke type cutter head. The panel type roadheader is safer than the spoke type; when encountering large gravel formations, the degree of freedom to increase the hob and the gravel breaking cutter is greater, while the spoke type is restricted when configuring the cutter due to the lack of a panel, and the degree of freedom to deal with is small; The spoke-type earth pressure management is easier than the panel-type. The soil bin of the cutter head can pre...
