Tunnel drilling rig (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 this 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, and only the drilling frame part, drilling frame and pumping station are moved. Can be operated separately within meters, which eases workers' movement of the pump
The drilling rig power head spindle and water shaft are integrated into one, 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 failure rate of oil leakage in the drilling rig.
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 square buckle that can be rotated forward and reverse. It can be equipped with a hydraulic holder 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 hydraulic motor of the drilling rig's power head can be The quick-change joint is connected to the hydraulic motor of the sealing pump for quick hole 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. This drilling rig adopts a hydraulic transmission mechanism, which has large drilling capacity, fast speed, simple operation, stable and reliable operation, and easy mobile installation. It solves the problems of blowout holes, hole collapse, and drill stuck during the drilling process of soft and protruding coal seams. The drilling rate is high and the drilling depth is deep.
When the drilling rig is equipped with a high-pressure water generator and a 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.
