Problems solved by technology
[0002] A variety of construction equipment is needed in the process of tunnel construction. Different tunnel shapes will be designed for each tunnel construction according to the specific situation. Common shield machines can only excavate tunnels with a fixed shape. For tunnels whose internal shape changes It usually needs to cooperate with other excavation equipment, which requires high cost, so a tunnel boring machine that can be applied to a variety of tunnel shapes and the excavation shape can be changed during the construction process is required

The invention provides a tunnel boring machine. The tunnel boring machine comprises a transverse boring module, a longitudinal boring module, a drill bit, four earth excavating modules, a transmissionshaft, a first gear, a driving platform and a screw. The tunnel boring machine is characterized in that the transmission shaft is rotatably installed on a transmission shaft seat of the driving platform, the first gear is arranged on the transmission shaft, and the first gear is engaged with two third gears on the driving platform; and one end, away from the driving platform, of the transmissionshaft is coaxial with a first rotary shaft of the longitudinal boring module and connected with the first rotary shaft of the longitudinal boring module in a welded mode, and the drill bit is rotatably installed at the end of the longitudinal boring module. According to the tunnel boring machine, a working mode that firstly hole drilling is conducted and then expansion is conducted all around is adopted, forward thrusting is conducted through the longitudinal boring module, the transverse boring module is linked with the earth excavating modules to excavate the periphery into a preset shape, the shape can be changed and adjusted in real time in the excavating process, the using amount of other auxiliary machines is greatly decreased in the excavating process, and the shape of a tunnel canbe formed at a time.
Description
technical field [0001] The invention relates to the technical field of civil engineering machinery, in particular to a tunnel boring machine. Background technique [0002] A variety of construction equipment is needed in the process of tunnel construction. Different tunnel shapes will be designed for each tunnel construction according to the specific situation. Common shield machines can only excavate tunnels with a fixed shape. For tunnels whose internal shape changes It usually needs to cooperate with other excavation equipment, which requires high cost. Therefore, a tunnel boring machine that can be applied to various tunnel shapes and whose excavation shape can be changed during the construction process is required. Contents of the invention [0003] In view of the above problems, the present invention provides a tunnel boring machine. The present invention adopts the working mode of drilling first and then expanding to the surroundings. The longitudinal excavation mod...
