XY-5A ⅠBrief XY-5A drill is a core drilling machine that adds drill tower and equips with wireline coring winch on the basis of XY-5 drill. It can realize move of the complete machine and can meet the new multi-drill technics and suit for multi- vocations,especially for the diamond drilling. It’s a spindle type drill. It has inherited many merits from the former type, such as simple structure, easy operation, and convenient maintenance. Except for the above merits, there are also some outstanding advantages as follows:1. XY-5A drill has a wide rotate speed range (50-1285rpm) with many velocity shelves (12 gearshifts) which are distributed in reason. It can meet the demand of various high efficiency drilling technics such as diamond rope sampling, impact gyration, directional drilling, counter-circle consecutive sampling and so on, and conventional method’s aperture matching. It suits for multi-drill technics.2. XY-5A drill can export big torsional moment whose intensity is high. Its drilling capability is strong. It can be used in wide range.3. Adopting the connecting rod reinforcement spring cramp and hydraulic pressure loosen normal close chuck whose structures are novel and compensate performance is good and hard alloy welding on spider, the clamping can be with large force, longevity and high reliability.4. Adopting the hydromatic brake, the drilling tools can be dropped at quiet and on the safe side, and the life of band type brake is long. Adopting hydraulic system of three oil pumps supplying oil, the design is comprehensive and the heat of system is decreased. The drill can match many kinds of implements to meet diversified operating conditions.5. Equipped with the brand automobile’s gearbox, clutch, universal transmission shaft and other high quality general parts which leads to long-life, high reliability and convenient replacement.6. XY-5A drill carries hydraulic lifting drill tower itself. It is convenient and agile to install it and to drill angle hole.7. The complete machine can be moved and it is convenient to remove it.8. The performance of matching is good, which is convenient for execution. Ⅱ Main Technical Specification
