Pneumatic column-type hydraulic trolley drill pipe has the characteristics of explosion-proof, large torque, high speed, small size, light weight, compact structure, and convenient disassembly. After disassembly, each part is less than 50Kg. Pneumatic column hydraulic jumbo drill pipe server rotation has forward and reverse functions, which can facilitate the hydraulic trolley drill pipe and release drilling equipment; the cutting tool adopts a separate motor, which has large feeding force and low equipment failure rate; according to the control air flow , Adjustable rotation speed and feed rate. This series of hydraulic trolley drill pipes can be used as supporting facilities for auger drill pipes and geological drill pipes, and are widely used for drilling water exploration, water irrigation, coalbed methane exploration and drainage in coal mines, pressure release holes, and anchor cable holes in coal mines. engineering construction.
Type of application field: hydraulic trolley drill pipe is generally suitable for coal roadway with rock hardness ≤ f10, especially for bolt support work in coal roadway. Mixing and installing epoxy resin coiled anchor cables and anchor rods, without using another one, can realize the one-time assembly and tightening of the anchor rod nuts to meet the requirements of the initial anchor pre-tightening force. Product advantages: small size, light weight, easy control and convenient maintenance. Transmission gear pneumatic pump, stable operation and high stability. The new design of fiberglass anti-corrosion air legs has high stability and longer service life.
Tilting rock drills that require assistance during operation are called portable rock drills; those that use pneumatic feet are called air-leg rock drills; those that use pneumatic column slide rails are called column drills. Frame guide rail type rock drill; there is also a pre-drilling machine equipped with a car frame, which is called a rock drilling jumbo.
