Fully hydraulic tunnel drilling rig for coal mines
Fully hydraulic tunnel drilling rig for coal mines. Tunnel drilling rig. Hydraulic drilling rig for coal mines. Water drilling rig. Xi’an tunnel drilling rig. Buying fully hydraulic tunnel drilling rig for coal mines.
Purpose and scope of use
Fully hydraulic tunnel drilling rig for coal mines is mainly used for drilling large-diameter gas extraction (discharge) holes, grouting fire prevention holes, coal seam water injection holes, outburst prevention and pressure relief holes, water exploration holes, and geological exploration in coal mines. holes and other engineering drilling. It is suitable for drilling various coal and rock formations with rock solidity coefficient. With the appropriate configuration of drill bits, drill pipes and other drilling tools, engineering operations such as coring and drilling of soft coal seams can also be carried out.
Main technical features
The drilling rig has a fully hydraulic power head combined structure. It is composed of hydraulic pump station, power head, frame, operating platform, column support and other parts.
, good disassembly performance, light weight of components, easy relocation and shifting of underground drilling rigs, and flexible drilling site layout.
, Unique hydraulic system, double pumps. The rotation parameters of the drilling rig can be adjusted independently, which improves the drilling rig's adaptability to various drilling processes.
The power head gyrator adopts dual motors, the transmission spindle has a through-hole structure, and the length of the drill pipe is not limited by the drilling rig's feeding stroke. Drill pipes of different lengths can be selected according to the construction conditions of the underground drilling site, and the application range is wide.
, hydraulic chuck and hydraulic clamper are used to clamp and unload the drill pipe, which is simple to operate, labor-saving, high-efficiency and safe.
The oil pipes are connected between the operating platform, pumping station and main engine, and the operation is centralized. Personnel can operate away from the wellhead, which is conducive to personal safety protection.
, four-column support, lifting cylinder to adjust the fuselage (i.e. drilling inclination angle is convenient and labor-saving.
, equipped with a variable pump for stepless speed adjustment, suitable for a wide range of working conditions.
