Abstract

The invention provides tunnel drilling equipment by adopting gas drive. A second motor and a first rotary platform are installed on a drilling supporting seat; a rotary device is installed at the bottom of the drilling supporting seat, and the rotary device can drive the drilling supporting seat to rotate; the rotary device is installed on a transmission mechanism, the transmission mechanism is connected with a first motor, and the rotary device is driven to move along a guide rail under the action of a controller controlling the first motor; the output end of the second motor is connected with the first rotary platform, the second motor drives a telescopic arm of the first rotary platform to swing at a first preset angle in the perpendicular direction of the length direction of the guiderail, and the first rotary platform is a swinging structure provided with the telescopic arm; a second rotary platform is installed at the output end of the telescopic arm; and a drill jig is connected to the output end of the second rotary platform, and the drill jig drives an impact drill on the drill jig to perform feeding motion through a pneumatic driving mechanism. Therefore, the tunnel drilling equipment by adopting the gas drive can improve the drilling efficiency.

Description

technical field [0001] The invention relates to the technical field of drilling, in particular to a tunnel drilling device driven by air pressure. Background technique [0002] The installation and construction of electrical and pipelines inside the tunnel requires drilling a large number of positioning holes on the tunnel wall, which has always been a labor-intensive job. Moreover, the safety of working at heights cannot be ignored. [0003] At present, in the tunnel construction in China, the drilling is done manually by climbing the ladder and drilling holes on the inner wall of the tunnel with the help of drilling tools. In addition, due to the harsh working environment in the tunnel, the maximum continuous working time of manual labor is generally not more than 4 hours. [0004] It can be seen that the drilling tools in the prior art need manual labor to drill holes on the inner wall of the tunnel, and the drilling efficiency is low.
