| titleOfInvention | A special hydraulic drilling, milling and boring machine for tunnels |
| abstract | The utility model provides a special hydraulic drilling, milling and boring machine for tunnels. The tunnel-specific hydraulic drilling, milling and boring machine includes: a main frame assembly; a traveling frame assembly, which is installed at the bottom of the main frame assembly; an operating room assembly, which is installed on the operating room assembly On the top of the main frame assembly; a lifting piece, the top end of the lifting piece is rotatably mounted on the rear end of the main frame assembly, and a stable shovel is rotatably mounted on the output end of the lifting piece. The hydraulic drilling, milling and boring machine for tunnels provided by the utility model, compared with the existing boring machines, has the advantages of simple overall structure and good mobility, only one operator is needed, and can be equipped with a convenient installation and disassembly. The cutting and milling head and rock drill bit for rock tunnel excavation greatly improve the progress of rock excavation and reduce the demand for energy and labor costs during the operation of the equipment. |
