Abstract

The invention discloses a pile shoe for posture regulation and protection of an underwater drilling machine. The pile shoe comprises a center barrel, wherein a ball hinged support is fixedly installed in an inner opening of the upper end step of the center barrel, the ball head end of a ball hinged connecting bar is arranged in the ball hinged support, a shearing device is arranged at the ball head end of the ball hinged connecting bar, a main panel is welded on the upper end face of the center barrel, a plurality of vertical plates are welded on the lower surface of the main panel and the circumference of the center barrel, and a plurality of side plates are welded on the outer vertical edge of each vertical plate. The pile shoe is simple in structure, compact in arrangement, light in weight, convenient to install, good in overall rigidity, and capable of effectively improving adaptation of the underwater drilling machine. Due to the grid structure formed by the side plates and the vertical plates, supporting stability of the underwater drilling machine is improved. Due to a stress screw structure or a transverse bar structure, the pile shoe is separated at a preset point when the recovered sling load reaches a set value, and structural safety of the underwater drilling machine and a hoisting cable of the underwater drilling machine is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of marine drilling rigs, and is installed on the leg of a subsea drilling rig special for marine sediment drilling and coring, and is used to support and adjust the posture position of the subsea drilling rig on the seabed, in particular to a pile for posture adjustment and protection of the subsea drilling rig boots. Background technique [0002] With the deepening of seabed exploration and development technology, drilling and coring has become one of the important means of marine engineering geological survey. At present, the sediment subsea drilling rigs used at home and abroad all take samples from the surface layer of the seabed. They can only be lowered into the seabed once and can only take cores with a single cylinder. Function and structure also can't be adapted to the drilling coring of seabed deep sediment. [0003] The spud shoe is one of the key equipment of the whole sediment drilling and cor...
