Abstract

The invention discloses a multifunctional drilling machine for a tunnel. The multifunctional drilling machine comprises guide rails, wherein T-shaped sliding chutes are formed in the two guide rails; the T-shaped sliding chutes are connected with T-shaped sliding strips in a sliding manner; the upper ends of the T-shaped sliding strips are connected with a bottom plate; the upper end of the bottom plate is uniformly connected with three guide rods and is rotationally connected with a threaded rod; the upper ends of the guide rods are connected with reinforcing rods; the upper end of the threaded rod penetrates through and is rotationally connected with the reinforcing rods; the threaded rod penetrates through the reinforcing rods and is connected with a second motor; the second motor is detachably connected with the reinforcing rods; the guide rods are connected with sliding sleeves in a sliding manner; the threaded rod is connected with a threaded sleeve; the threaded sleeve and the sliding sleeves are connected with a base; the base is detachably connected with a hydraulic device; the hydraulic device is connected with a first fixing plate; one end, which is close to the hydraulic device, of the first fixing plate is connected with two telescopic rods; the telescopic rods are connected with telescopic sleeves in a sliding manner; and the telescopic sleeves are connected with the base. The height and the left-right direction of the multifunctional drilling machine can be adjusted within a certain range, so that the drilling efficiency is improved, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of tunnel construction equipment, in particular to a multifunctional drilling machine for tunnels. Background technique [0002] A tunnel is an engineering building buried in the ground, and it is a form of human use of underground space. At present, in the construction of railways, highways, water canals and other projects in China, tunnel blasting is required during the construction of some tunnels with relatively hard geology, and blast holes for preventing explosives need to be drilled on the face of the tunnel between blasting. At present, the drilling of blast holes is still done manually by drilling rigs. Some blast holes at higher positions require workers to use scaffolding, and then the drilling machine (or down-the-hole drill) is placed on the scaffold, and each hole is drilled. Finally, the down-the-hole drill is manually moved up or down along the scaffold, left or right to the next drilling po...
