Description

Technical Field

[0001] The utility model relates to a full hydraulic core drilling rig, in particular to a portable full hydraulic core drilling rig. Background Art

[0002] The current core drilling rig uses a hydraulic motor to directly drive the power head, and the torque is small. Although the torque can be increased by replacing the hydraulic motor, it is difficult to disassemble and assemble, which loses the fundamental meaning of portability; the wire rope on the hydraulic winch is guided by the pulley in the crown block assembly for rope coring, and a certain lateral angle is formed between the wire rope and the crown block assembly. Therefore, the side wall of the pulley is always subjected to the lateral force brought by the wire rope, which makes the side wall of the pulley extremely easy to be damaged, and the service life is greatly reduced. In addition, the wire rope is also very easy to jump, which is extremely inconvenient to use; the drilling angle of the drilling rig is completely adjusted by lifting the mast by manpower, which is inconvenient to operate and has relatively low safety performance. It not only faces a large potential source of danger, but also wastes a lot of manpower, which will inevitably increase the cost of use, thus affecting the economic benefits of the portable drilling rig project.
