Summary: | The invention relates to a unified driving and proof machine. Specifically, it is backplate of cutting section of header used as drilling platform under the support of cutterhead to unify the roofproof machine andcutting section of header The up-and-down, swaying and functions of the cutting section finish suppotring roof in the tunnel temporarily. Meanwhile, the equipment can be stretched and folded. When the excavator is working, roofproof machine will withdraw to the back of the excavator to spare the space. This equipment combines the excavator and drilling machine together. The roofproofmachine is set on the top of the excavator. These two are connected by tracks. The invention uses backplate of header section as drilling platform, which can stretch forth-and-back, sway left-and-right, be adjusted in height, and revolve itself to accomplish the tunnel drilling. When the excavator is working, the roofproof machine can withdraw from backplate of cutting section to the back of the excavator, thus it greatly |
