Main Features of Full Hydraulic Core Drilling Rig
- The top-driven power head adopts foreign technology. Its structure is dual motors and mechanical shifting. It has a large shifting range and large low-speed end torque. It is equipped with different motors is suitable for the requirements of different drilling methods and meets various construction methods.
- The power head has high transmission precision and smooth operation. The advantages are even more evident when drilling deep holes.
- The feeding and lifting system adopts a cylinder chain multiplication mechanism, which has a long feeding distance and is convenient for long-core coring operations.
- The power head adopts the method of automatically opening the hole and is equipped with a holder, a shackle, and a drill pipe centralizer, which can quickly and easily complete the rope coring operation of straight holes and inclined holes, eliminating the need for traditional secondary operations. Platform operation, high degree of automation, and easy operation.
- The drilling rig has a fast lifting and feeding speed, which saves a lot of auxiliary time. During full drilling, it is convenient for hole cleaning and improves drilling efficiency.
- The main tower guide rail adopts a V-shaped structure. The connection between the power head and the main tower has high rigidity, stable high-speed rotation, and a high scoring rate.
- The main winch adopts imported products, with stable lifting and reliable braking.
- The hollow rope speed of the rope coring winch reaches 205m/min, which reduces the auxiliary time.
- The drilling rig is equipped with a clamper and a shackle, making it easy and quick to disassemble the drill pipe, reducing labor intensity.
- 10 The drilling rig is equipped with a power head tachometer and drilling scale to facilitate user selection of parameters.
- The drilling rig feed adopts a pressure preparation balance, which can easily understand the pressure value at the bottom of the hole and improve the life of the drill bit.
- The hydraulic system of the drilling rig is reliable. The mud pump and mud agitator are hydraulically controlled. All drilling rig operations are centralized, making dealing with various underground accidents easy.
- The drilling rig adopts a crawler type and is easy to move. It adopts external handle control to make movement safe and convenient.
