Introduction to ZDY650 hydraulic tunnel drilling rig

Type Hydraulic Tunnel Drilling Rig Parameters Type Hydraulic Tunnel Drilling Rig Introduction
Type Hydraulic Tunnel Drilling Rig for Coal Mines is mainly used for drilling underground coal mines for gas pumping (drainage), draining holes, grouting fire prevention holes, coal seam water injection holes, anti-outburst pressure relief holes, and water exploration Geological exploration holes and other underground engineering drilling holes in coal mines. It can be used with core drilling tools for core drilling. Drill bits and drilling tools of different specifications, models and materials can be used to drill holes for different purposes in different coal seams and rock formations.
Characteristics of hydraulic tunnel drilling rig
Power head hydraulic drilling rig consists of the following parts: hydraulic pump station, power head frame, console column support, etc.
Because it is a split-timber structure, it is easy to transport and install underground.
Unique hydraulic system, full hydraulic transmission, easy and labor-saving operation.
Because it is connected by oil pipes and equipped with a blowout preventer drill pipe, the operator can stay away from the wellhead when the drilling rig is working, which is safer.
When the drilling rig is working, the power head frame support is a frame-type support. Several holes can be drilled up, down, left, and right in one installation, which saves auxiliary time and is highly efficient.
Working Principle of Hydraulic Tunnel Drilling Rig
The electric motor drives the oil pump, which transports two streams of hydraulic oil through the operating table and one stream of pressure oil to the hydraulic motor connected to the reducer. After deceleration, it outputs power to drive the drilling tool to rotate. . Another stream of pressure oil is delivered to the oil cylinder to push the piston back and forth, which can drive the power head to feed, return or start the drilling tool. Rotate the throttling handwheel clockwise and counterclockwise to adjust the drilling feed speed of the drilling rig. Operating the corresponding handle can control the action of the hydraulic chuck of the hydraulic clamper, loosening and unloading, clamping the drill pipe, as well as the lifting and lowering of the frame and the adjustment of the drilling or installation angle.
