Abstract

The invention relates to a tunnel underground excavation machine, which comprises a vehicle frame (1), wherein an electric control device (2) and a cab (3) are arranged above the vehicle frame; a crawler traveling device (20) is arranged under the vehicle frame (1). The tunnel underground excavation machine is characterized in that a main sleeve (6) ascending and descending in a vertical direction is also arranged on the vehicle frame; an axial line of the main sleeve (6) is arranged along the length direction of the vehicle frame (1); a sub sleeve (7) sliding along the axial direction of the main sleeve (6) is arranged in the main sleeve (6); one end of the sub sleeve (7) is connected with a cutter head frame (11); at least one cutter head driving device (9) is arranged on the cutter head frame (11); a power output shaft of each cutter head driving device is connected with a milling-planing cutter head (10). The tunnel underground excavation machine has the beneficial effects that the structure is simple; the safety is high; the excavation can be performed in the full cross section range of a tunnel; the layered excavation can be performed according to the practical condition of the tunnel; the fully mechanical operation of the tunnel underground excavation construction is realized; the characteristic of wide application range is realized.

Description

technical field [0001] The invention relates to underground excavation equipment, in particular to a tunnel underground excavator. Background technique [0002] At present, in the construction of tunnel projects such as railways, highways, subways, and drilling mountains, shield machines and concealed excavation machines are mainly used to complete. Due to the complex structure of the tunnel, especially when constructing the platform, it is necessary to excavate the upper and lower layers in layers, which cannot be completed by the existing shield machine and concealed excavation machine, so manual underground excavation can only be used. The excavation efficiency of this method is very low when constructing the platform, and it also increases the labor intensity and safety risks of the operators, and also prolongs the construction period. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the tunnel boring equipment in th...
