Description
Technical Field
[0001] The utility model relates to the technical field of drilling equipment, in particular to an airborne rear-mounted reinforcement drilling rig. Background Art
[0002] At present, pneumatic anchor drill is used to drill holes for anchor cable construction behind the tunnel boring machine on the excavation face. The tunnel height is above 3.8, which is beyond the reach of the pneumatic anchor drill. A heightening platform is placed below. Because the ground below the platform is uneven, the pneumatic anchor machine on the platform drills anchor cable holes, and the platform is at risk of tilting and falling, which brings safety hazards to coal miners during construction. The current excavation and exploration consists of two parts. First, a coal tunnel drilling rig is installed to drill 60m of exploration holes along the tunnel construction direction. After confirming safety, the drilling rig is dismantled and the tunnel boring machine is entered for excavation. After excavating 40m, the tunnel boring machine is exited and the drilling rig is installed to repeat the next cycle. In this way, a large part of the time is spent on the installation of the drilling rig equipment, which not only increases the labor intensity of the workers, but also affects the work efficiency of tunnel excavation. At the same time, when the drill rod equipment is drilling at the bottom layer, the drill rod will wear due to long-term friction and mechanical vibration of the drill bit, and the drill rod needs to be replaced frequently for maintenance.
