Details

Crawler rock drill to cater to the market demand the development of a new type of DTH drill rig, the excellent product performance, flexible operation, complete function, adaptability, has high cost performance. Crawler rock drill can be widely used in open-pit mining, foundation excavation construction, water conservancy, power plants, transportation and national defense construction and other engineering drilling in the drilling, also can drill bore anchorage, addresses, pressure measurement and drain and other special purpose of rock hole. The structure of the drill shank is novel, easy to adjust, and the performance of the drilling operation is greatly improved. Use the low-level horizontal hole of the drilling world. The minimum height of the horizontal hole is 300mm.

FAQ

Q1: How does the crawler rock drill work?

A: Open-air DTH drill rig with diesel engine power, formed by hydraulic oil pump drive high pressure oil, by manipulating control on the stage of each related hydraulic control valve, drive hydraulic motor, hydraulic cylinder complete all scheduled action. When in operation, the power is activated to push the handle on the rotary control valve. The pressure alone drives the rotary motor on the rotary machine to rotate through the rotary control valve. Push the handle on the walking control valve to achieve the actions of the entire machine such as moving forward, backward and turning. Push the handle on the cylinder control valve to control each related cylinder to complete the pitch, swing, compensation of the guide rail and the pitch action of the drill arm. Push the handle on the propulsion control valve to achieve the extension and retraction of the propulsion cylinder, driving the chain to feed and lift. When the propulsion cylinder contracts and the rotary unit rotates forward, the ball valve on the intake pipe is simultaneously opened to supply the pressurized air supplied by the air compressor into the drill pipe and the impactor. The impactor works and blows the crushed rock out of the ground, thus achieving continuous feed of the crushed rock by the impactor and forming rock drilling and piercing.

Q2: The jumbo steps?

A: 1. Start the engine, hydraulic system no-load running 10~20 minutes.
2. Promote walking control valve will drill the car to the borehole location; Push each handle on the longitudinal valve to adjust the guide rail to the perforated position. Note: you must see to it that the front-end localization support while working on the work of borehole.
3. Open the inlet pipe ball valve switch, on the road to the impacter plenum, at the same time promote in longitudinal valve, make the transfer back to drive the drill pipe, impact device is turned, and then slowly push in longitudinal valve, make the drill bit gradually close to the ground, according to touch the ground after the impacter began to work.
4. Because pumice or cracks, should be repeated at the beginning of controlling propulsion controlling valve handle, turn back around to drive pipe, is constantly improve and improve, make the hole in the rubble and debris in time to prevent sticking.
