Abstract

The invention relates to a seabed type conical investigating and drilling integrated machine which comprises a tower, a power head, a drilling tool storeroom, a manipulator mechanism, a leveling mechanism, an instrument box, a winch, a drilling tool, a clamp holder and a hydraulic pump. According to the drilling process of a seabed drilling machine, the power head provides the rotation power and realizes the feeding and recycling of the drilling tool through a tower guide rail on the tower; the drilling tool storeroom is arranged on the two sides of the power head and used for storing variousdrilling tools; the drilling tools are automatically stored and fetched through the manipulator mechanism, and the leveling mechanism keeps the drilling tool vertical to the seafloor when the integrated machine works; a core barrel for wire line coring is released and recycled by the winch; and the drilling tool is clamped and removed by the clamp holder. The integrated machine provided by the invention has a scientific and reasonable structure, is simple and convenient to control and safe and reliable to use and is suitable for the large-depth deep hole core sampling on seabed and also for operation on land.

Description

technical field [0001] The invention relates to a geological drilling equipment, in particular to a seabed type cone drilling and drilling integrated machine, which is a kind of marine exploration equipment integrating the functions of cone drilling and drilling. Background technique [0002] In the exploration activities of marine geological resources, seabed sampling equipment and instruments play an indispensable role. It is of decisive significance to the prediction and evaluation of mineral resources. The integrated drilling and sampling machine provides technical support for deep-sea exploration, and its technology can also be well applied in other deep-sea equipment, which also promotes the development of my country's submarine engineering, geological science, and deep-sea machinery and electronics. However, the research and development of the domestic subsea drilling and sampling integrated machine is slow. The fundamental reason is that the seabed drilling rig is a c...
