Rig industry in China rise late, but as China's economic development, the rapid rise of construction throughout the building, rig this rising star in the international rig market development show a unique charm. Drill Development is the epitome of China's construction machinery development rig also represents the future trend of machinery development. Rig was placed a lot of expectations and concerns. Rig toward multi-functional, efficient, intelligent, precision of direction. Drill anchor hole drilling pit urban high-rise buildings (overburden drilling with pipe). Railway tunnel construction process with the same pipe roof drilling process. Rig applications: ground source heat pumps and hydropower cofferdam grouting hole drilling. 1. If the overburden depth ≤30 meters, and the sand and gravel is relatively small, can be imported power head rotary single-acting double rotation, that is, within the drill pipe, casing while rotating and shock, using high-pressure water slag, drills, pulling high casing efficiency and reduce construction costs. The use of high pressure air DTH drilling in bedrock, drilling to a depth of 250 meters. 2. If the overburden depth> 30 meters, rig Which is cheaper, sand or gravel is relatively large, can be realized using imported power head drill pipe, casing while rotating, the impact of the use of high pressure DTH with eccentric / expansion of the heart Drilling Head implementation. On the bedrock utilizing high pressure pneumatic DTH hammer drilling, drilling depth of 250 meters. Rotary drilling rig repair and maintenance of rotary drilling rig mainly by the usual maintenance to ensure high frequency rig use, operation need to operate in accordance with specifications, rotary drilling rig on a regular basis to check various parts, but also pay attention to the replacement of various oil products . 1, diesel fuel: oil and water separator discharge once a day, every day discharge tank once the tank cleaned once every six months, according to the actual situation with the replacement filter. 2, engine oil: first 50 hours change the oil and filter, normal replacement after every 250 hours. 3, engine coolant: every 2,000 hours to replace a replacement filter cartridge every 1 thousand five hundred hours or one year. 4, gear oil: Power head every 2,000 hours to replace a power head gear for the first time 50 hours replaced after every 2,000 hours to replace a rig Which is good, hoist the first 50 hours replaced after every 2,000 hours to replace. 5, hydraulic oil: every 3,000 hours to replace once every five hundred hours to replace the filter once. 6. Grease: drill bearing and traction butter play once a day, a month to play a rotary shaft body butter. 7, rope: Regularly check for wear. Required timely maintenance and proper handling, can reduce the frequency of the rig failure, improve the efficiency of the rig, save money and improve efficiency.
