Description

Technical Field

[0001] The utility model relates to the technical field of rock drilling, in particular to a rock drilling device for a tunneling machine. Background Art

[0002] At present, domestic coal mine tunnels are mainly excavated by tunnel boring machines, and domestic mountain tunnels are mainly excavated by blasting. There are also tunnel boring machines. However, both tunnel boring machines and blasting have some problems in the construction process. For example, during the construction of tunnel boring machines, if a section with high rock hardness is encountered, the pick will wear quickly, and the construction cost will increase while the construction efficiency will decrease. Of course, when the tunnel boring machine encounters hard rock, there are also cases where blasting holes are drilled first and then blasting is used. In this case, the safety factor is low, and the noise and pollution are relatively large.

[0003] The patent with the patent announcement number CN204716250U discloses a rock drilling device for a tunnel boring machine, including a guide frame, a drill frame push-pull cylinder, a base frame, a power head assembly, a drill frame, and a power head push-pull cylinder. The base frame is fixedly mounted on the cutting part, and the drill frame push-pull cylinder is respectively hinged to the drill frame and the base frame, and the drill frame moves forward and backward under the drive of the drill frame push-pull cylinder extension and contraction; the power head push-pull cylinder is respectively hinged to the drill frame and the power head assembly, and the power head assembly moves forward and backward under the drive of the power head push-pull cylinder extension and contraction. The above patent has the following shortcomings: Although the patent can improve the safety factor during drilling, it can only drill one hole on the rock wall at a time. However, when multiple holes need to be drilled on the rock wall, its drilling efficiency needs to be improved. In view of this, we propose a rock drilling device for a tunnel boring machine.
