Abstract

The invention relates to a novel submarine deep hole pressure maintaining and core drilling rig. The space of a drilling rig is insufficiently used by an existing device, and the processes of drilling, sampling and pressure maintaining for samples are complicated. The novel submarine deep hole pressure maintaining core drilling rig comprises an outer frame, a support leveling mechanism, a drilling pipe and core barrel storage mechanism, a power head mechanism, a rope core-stripping mechanism, a main manipulator, an auxiliary manipulator, an assembly manipulator, a pressure maintaining cover storage mechanism, a hydraulic motor, a drilling pipe, a core barrel and a hydraulic power system, wherein the main manipulator (the auxiliary manipulator) comprises a hydraulic lifting cylinder, a rotary support column, a base, a pipe taking gripper and a telescopic arm, and the assembly manipulator comprises a rotary support column, an upper pressing cover arm, a lower pressing cover arm, a rotary cover mechanism and a base. The space of the drilling rig is sufficiently used for storing more drilling pipes and core barrels, the drilling rig is applicable to multi-depth drilling places, the pressure of a sample can be maintained, operation is convenient in the pressure maintaining process, and cost is low.

Description

technical field [0001] The invention belongs to the technical field of marine exploration machinery and equipment, and relates to a novel seabed deep-hole pressure-maintaining core drilling rig. Background technique [0002] The development of marine resources, especially the development of seabed mineral resources is a new technical field, but the detection of seabed resources is difficult due to the constraints of changing geology and ocean currents. extremely high requirements. Most of the existing deep-sea mineral exploration equipment uses deep-sea drilling rigs or corers for deep-sea in-situ measurement. Such exploration equipment often needs to be realized by remotely connecting and unloading multi-section drill pipes when performing deep hole drilling. [0003] Patent 190310107888.0 discloses a deep-sea coring device with pre-feed and pre-positioning devices. The mechanism utilizes two pre-propelled hydraulic cylinders installed in parallel to replace the complex ...
