XY-44B core drilling rig for geotechnical exploration sampling
XY-44B core drilling rig with diamond bit and alloys bit is mainly used for core drilling . It applied for different construction such as geological exploration, hydrological wells, shallow oil, gas, geothermal, and large-diameter cement pile for foundation construction.
1. Drilling rig with reasonable structure, light weight and large capacity, it has wide-range application, stable performance, high reliability, and high degree of standardization.
2. Save cost of accessories to choose standard automobile gearbox clutch with reliable performance, flexible operation. It has 8 levels speed stages and a reasonable speed range, and the torque is powerful under low-speed (up to 4200N.m).
3. With double-cylinder hydraulic power feed for long stroke, and large hole diameter (Φ93mm) of vertical shaft, It’s especially suitable for large diameter drill rod in wireline coring drilling.
4. Having large drilling capacity, rated drilling depth of Φ71mm wireline coring drill rod is 1000m.
5. Light weight, low center of gravity, compact structure, good detachability, reasonable structure, easy to maintain and repair, the host has detachable 10 parts (the maximum detachable part weight is 300kg), facilitates moving, especially suitable for mountainous areas, mining and tunnel work.
6. The hydraulic chuck with strong holding force, adopts two-way oil supply and is equipped with a hydraulic lock, which ensures stable clamping.
7. Equipped with water brake system, under deep hole drilling, it is safe and stable.
8. The gear oil pump is used for oil supply, which has low power consumption and stable operation. The system is equipped with a hand-operated oil pump. When the power machine cannot work, the hand-operated oil pump can still be used to pull out the drill tool in the hole.
9. Long displacement distance (up to 460mm), firm fixation, and high-speed drilling stability.
10. Anti-vibration instruments with a long service life, which is beneficial to know the situation in the hole. Flexible and reliable operation.
11. High degree of common use, the common parts of this machine matching XY series drilling rig are more than 60%.
Supporting drilling tools
1. Equipped with common geological drilling tools for geological exploration and core drilling.
2. It can be seamlessly connected with domestic and foreign drilling tools through adjustable joints.
