Characteristics of KY-800 rope core drilling rig

KY-800 full hydraulic rope core drilling rig is mainly designed for metal mines and non-coal mine users Φ60, Φ75mm bore deep hole drilling engineering needs, to make up for the vertical shaft surface drilling rig and full hydraulic portable drilling rig shortage. Suitable for most mine geological conditions and formation structure, KY-600 full hydraulic tunnel drill has achieved a comprehensive upgrade and transformation of technical parameters on the basis of improving the spindle output torque, clamping force of the holder and lifting force of the cylinder, both drilling efficiency in shallow holes and drilling capacity in deep holes have reached a new height on the construction site. The drilling depth of Φ75mm horizontal hole coring is not less than 600 meters, and the downward hole is not less than 750 meters.

1, and KY-600 drill machine has the same spindle output speed suitable for diamond high-speed drilling, to maintain the drilling efficiency in a deeper state; The spindle has a higher output torque and a stronger deep hole drilling capability.

2. The power source and hydraulic energy are reasonably distributed by the group power design, which makes the performance of KY-800 tunnel prospecting rig accurately improved, effectively reducing pressure loss and improving mechanical efficiency.

3, the use of double-acting normally closed gripper, eliminate the partial clamping force generated by the lever weakened, in the upward and downward azimuth hole drilling process has a more reliable performance.

4, the hydraulic system has been comprehensively upgraded, and the internal structure and size of the multi-channel reversing valve have higher accuracy requirements and tolerance requirements. Optimized the design of high pressure pipeline, suction pipeline and return pipeline, and strictly calculated the flow rate, pressure and flow rate of the liquid, eliminated the time difference of the general hydraulic system linkage process, and the deep hole drilling ability was outstanding.

5, the power distribution cabinet starting system can realize wireless remote control start and stop, suitable for different underground working conditions, especially in the case of water in the work site in the tunnel, we can start and stop the main motor and mud pump motor within 100 meters of the visual range, greatly improving the safety.

6, modular design, split structure is suitable for installation and handling in the limited space environment in the tunnel.

7, can achieve 0°~360° arbitrary Angle of drilling coring work.

8, there is a better hydraulic linkage performance, to achieve the drilling, drilling, twist off drill pipe and other mechanical control, no manual unloading drill pipe; The gripper, master cylinder and chuck are responsive and do not damage the drill pipe, which greatly improves the working efficiency and the service life of the drill pipe.

9, in the limited space environment of the tunnel can achieve arbitrary inclination drilling, then in the open surface engaged in geological exploration operations more convenient, its installation and fixing method and full hydraulic portable drill the same, simple, easy to control.

10, the hydraulic system is the central system of the rig, the hydraulic station of the model of the oil return cooling effect is significant, the oil return resistance is small, can improve the heating condition of the system, so as to maintain the benign operation of the equipment. The filter precision of the tank is high, which can improve the service life of the motor, oil pump and other hydraulic actuator components and reduce the incidence of failure.

11, KY-800 drill clamp has more sufficient clamping force, in the normally closed state of clamping force, high sensitivity in the opening and closing process of the clamp, high durability of the disc spring.

12. The lifting force of the feeding cylinder under the same feeding pressure can be more significantly improved than that of KY-600 drilling rig.

13. The cylinder sealing performance of the drilling rig is more reasonable, the sealing structure is optimized, and the service time of the execution components is improved.
