Embodiment Construction

[0043] The present invention will be further described below in conjunction with accompanying drawing.

[0044] Such as figure 1 As shown, the tunnel boring machine 10 includes a cutter head 1 arranged along an axis 11, a shield 2, a main drive mechanism 3, a main beam 7 and multiple other structures or components arranged on the main beam 7, such as a steel arch installation mechanism 4 And bolter assembly 5.

[0045] The cutterhead 1 is at the forefront of the tunnel boring machine 10 and is used for drilling into the formation. The main driving mechanism 3 is used to apply driving force to the cutter head 1 . Shield 2 is used to initially support the tunnel walls of the tunnel that has just been drilled. The steel arch installation mechanism 4 adjacent to the shield 2 and arranged behind is used to support the tunnel. The bolter assembly 5 arranged behind the steel arch installation mechanism 4 is used to punch holes into the tunnel wall and insert reinforcements such a...

Abstract

The invention relates to a tunnel boring machine. The tunnel boring machine is suitable for excavating tunnels with the diameter being 6.8-7.9 m. The tunnel boring machine comprises a main driving mechanism for driving a cutterhead, a transmission mechanism, the cutterhead and a shield, wherein the main driving mechanism comprises a plurality of driving power source assemblies; the transmission mechanism is driven by the multiple driving power source assemblies; the cutterhead is connected with the transmission mechanism; the shield surrounds the main driving mechanism in the circumferential direction; and the dimension of a shell of the shield can be changed so that the shell of the shield can adapt to the diameter of a tunnel to be excavated. When the diameter of the tunnel to be excavated is 6.8-7.9 m, only part of structures of the tunnel boring machine need to be changed, overall modification is not needed, in this way, universality of main parts and components can be achieved, the design and manufacturing cycle is greatly shortened, and production cost is greatly reduced.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a tunnel boring machine. Background technique [0002] With the rapid development of the national economy, the urbanization process continues to accelerate, which leads to the need for a large number of tunnel boring machines in domestic urban subway tunnels, hydraulic tunnels, river-crossing tunnels, railway tunnels, highway tunnels, municipal pipelines and other tunnel projects. Tunnel boring machine is a highly intelligent tunnel construction major technical equipment integrating mechanical, electrical, hydraulic, optical and computer technologies. The implementation of the domestic industrialization of tunnel boring machines can not only break the dominance of foreign companies in the domestic market, but also promote and drive the development of related electromechanical, hydraulic, material, sensor and other industries, enhance the comprehensive strength of the equipment manufacturin...
