Problems solved by technology

The first thruster and the first supporter of the device work in the hard rock cutting mode, and the second thruster and the second supporter work in the soft soil cutting mode of the shield, wherein the second supporter is the cement segment for constructing the tunnel, Unable to fully automate continuous excavation in hard rock or soft soils, or step change in vertical tunnels
[0007] The known TBM tunneling device has a single working mode and cannot select different tunneling operation modes for specific support surfaces or working conditions of the tunneling surface, and has poor adaptability to the environment
[0008] The known TBM tunneling devices have the following problems: one is that there is no fully automatic continuous tunneling function or step-changing operations in vertical tunnels
Second, although some have this function, the working space is limited
The third is that the working mode is single, and the environmental adaptability to the support surface or the excavation surface is poor

Abstract

A fully automatic TBM tunneling device with double hexapod propellers and double three-leg supporters, which is composed of a support ring (2), a main propeller (3), a main supporter (4), an auxiliary propeller (5) and The auxiliary support (6) is a parallel device formed in series. Its topology will change with the loading or unloading state of the main supporter and auxiliary supporter. The double hexapod propellers can alternately complete the propulsion work, and can realize fully automatic continuous excavation operations. The double-tripod supporter can work in parallel, can make it evenly load or load according to a given ratio, and can change steps in vertical tunnel excavation operations. The tunneling device of the present invention can work in several different working modes such as single-ring tunneling, double-chain tunneling, triple-chain tunneling, and fully automatic continuous tunneling, so as to adapt to different working conditions of tunneling surfaces and supporting surfaces. The invention is suitable for TBM tunnel excavation, mineral excavation or pipeline operation, especially suitable for excavation operation of tunnels or vertical tunnels with complex and changeable excavation surfaces and support surfaces.

Description

technical field [0001] The invention relates to a fully automatic TBM tunneling device with double hexapod propellers and double tripod supports, belonging to the technical field of tunneling machinery. Background technique [0002] The known TBM excavation device includes four parts: a supporter, a propeller, a step changer and a direction adjuster, which respectively complete the support operation, propulsion operation, step change operation, direction adjustment or deviation correction operation in sequence; the excavation device can push The support ring and the cutterhead system on the support ring complete the tunnel cutting work. [0003] Some known TBM excavation devices have only one supporter, such as the main beam type and torsion cylinder type TBM excavation device, and the excavation process includes the supporting operation step-propelling operation step-changing operation step-adjustment or deviation correction completed in chronological order Operation step,...
