Tunnel drilling rig is hereinafter referred to as drilling rig. This drilling rig is designed and manufactured based on the latest needs and improvement suggestions for on-site use in mines with soft and protruding coal seams. Outstanding features of this drilling rig: The pumping station of the drilling rig has high pressure, the drilling frame is light in weight, and is easy to move and install. When moving the drilling rig to another drilling site, the pumping station and power supply do not move, only the drilling frame part is moved, and the drilling frame and pumping station can be separated. Operating within meters eases workers from moving the pump
The power head spindle and water shaft of the drilling rig are integrated, reducing the hexagonal shaft and hexagonal sleeve shaft of the traditional drilling rig
The drilling rig adopts a new special sealing ring, thereby reducing the need for The failure rate of oil leakage in drilling rigs has been reduced.
This drilling rig is equipped with a spiral drill pipe with wide blades, hollow square buckles and can be rotated forward and reverse. It can drill with water or pressure air to remove slag.
When the drilling rig leaves the factory, it can be equipped with a tapered smooth drill pipe or a tapered spiral drill pipe or a spiral drill pipe with a square buckle that can be rotated forward and reverse. It can be equipped with a hydraulic clamp and a manual clamp that can quickly disassemble the drill pipe. The holder can realize the multi-purpose use of one machine when purchasing a drilling rig for coal mines
According to the user's requirements, the drilling rig can be equipped with a dedicated hydraulic sealing pump. After drilling, the quick-change valve on the hydraulic motor of the drilling rig's power head can be The joint is connected to the hydraulic motor of the sealing pump for rapid sealing.
The drill frame has two structural forms: column frame and seat frame. Different drill frames can be selected according to the tunnel section of the coal mine and on-site usage conditions. The drilling rig adopts a hydraulic transmission mechanism, which has high drilling capacity, fast speed, simple operation, stable and reliable operation, and is easy to move and install. It solves the problem of blowout holes collapsing and stuck drill holes in soft and protruding coal seams during the drilling process. The drilling rate is high and the drilling depth is deep.
When the drilling rig is equipped with a high-pressure water generator and high-pressure sealed drill pipe, it can cut coal seams with low gas permeability, thus improving the gas drainage efficiency and greatly shortening the drainage time.
