Fully hydraulic tunnel drilling rig for type coal mines
Fully hydraulic tunnel drilling rig Drilling rig performance Gas drainage coal seam water injection drilling rig Tunnel drilling rig Shaanxi water exploration and drainage hydraulic tunnel drilling rig
Purpose and scope of application
For type coal mines Fully hydraulic tunnel drilling rigs are mainly used for drilling gas pumping (drainage) holes, grouting fire prevention holes, coal seam water injection holes, outburst prevention and pressure relief holes, water exploration holes, geological exploration holes and other engineering drilling holes in coal mines. 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, convenient for 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 rotary spindle adopts a through-hole structure, and the length of the drill pipe is not limited by the feed stroke. The drill pipe can be configured according to the conditions of the underground drilling site.
, hydraulic chuck and hydraulic clamper are used to clamp and unload the drill pipe, which is simple to operate, high efficiency, labor-saving and safe.
The oil pipes are connected between the operating platform, pumping station and main engine, and the operations are centralized. Personnel can operate far away from the wellhead, which is beneficial to personal safety.
, 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.
