Automatic drill jumbo for tunnel and working method thereof

Abstract

The invention discloses an automatic drill jumbo for a tunnel and a working method thereof. By means of the automatic drill jumbo for tunnel and the working method thereof, the problem that in the prior art, due to the fact that excavation is conducted through manpower, multiple defects exist is solved. The automatic drill jumbo for the tunnel comprises a jumbo frame structure which is provided with working platforms, and each working platform is provided with a mechanical arm system; each mechanical arm system comprises a rotary seat structure, a mechanical arm arranged on the rotary seat structure and a clamping device which is arranged at the tail end of the mechanical arm and used for being installed with a drill bit; each rotary seat structure can drive the corresponding mechanical arm to rotate along the cross section of the jumbo frame structure, and each mechanical arm can drive the corresponding clamping device to move upwards in the height direction of the jumbo frame structure; each working platform comprises a sliding rail system and a feeding system, each mechanical arm system is installed on the corresponding sliding rail system through the corresponding rotary seat structure and can move in the length direction of the jumbo frame structure through the corresponding sliding rail system, and each feeding system is used for providing power to make the corresponding mechanical arm system move on the corresponding sliding rail system.

Description

technical field [0001] The invention relates to a trolley, in particular to an automatic tunnel drilling trolley and its working method. Background technique [0002] At present, the excavation of tunnels is mainly carried out by workers holding pneumatic drills and standing on the excavation trolley after drilling and then blasting. Drilling is carried out in groups, and the path of the drilling hole needs to have a certain angle with the axis of the tunnel according to the layout of the hole; after the hole is drilled, the detonator is put into the drilled hole to blast the rock wall, and then the slag is cleaned to complete the excavation of the tunnel. [0003] The excavation trolley is mainly a frame structure welded by I-beams, and a layer of steel mesh is laid on it. Drilling workers stand on the excavation trolley, use the pneumatic drill air legs as support, and hold the pneumatic drill to drill. For example, excavating a one-way two-lane tunnel section in V-level ...

AI Technical Summary

Problems solved by technology

For example, excavating a one-way two-lane tunnel section in V-level surrounding rock requires about 13-15 drillers, the number of drilling holes is about 140, and the drilling depth is about 5m. On the one hand, the labor intensity of workers is high, and dust And the noise pollution is serious, and the health of the workers is bound to be affected in the long run; on the other hand, the work efficiency is very low, and the labor cost is added, and the expenditure is relatively large
