() Hydraulic tunnel drilling rig for coal mines (hereinafter referred to as the drilling rig). This drilling rig is designed based on the latest needs and improvement opinions for on-site use in coal mines. Designed and manufactured. The 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 can also solve the problems of blowout holes, hole collapse, drill stuck, etc. in the process of drilling in soft and protruding coal seams. . The drilling rig has high hole formation rate and deep drilling depth. The outstanding features of this drilling rig are:
The drilling rig pump station has high pressure, the drilling frame is light in weight, and it is easy to move and install. In the process of moving the drilling rig to another drilling site The pumping station and power supply do not move, only the drilling frame part is moved. The drilling frame and pumping station can be operated separately within meters, which reduces the labor intensity of workers moving the pumping station.
This 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 characteristics 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 joint on the hydraulic motor of the drill power head can be connected to the hydraulic motor of the sealing pump for rapid sealing. hole.
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.
