The invention provides a pile leg locking device and a locking method thereof. The device comprises a pile leg and further comprises a main shaft. The pile leg comprises a rack and a chord pipe, a gear engaged with the rack is installed on the main shaft, and supporting seats are symmetrically arranged on the two sides of the gear; one end of the main shaft is connected with a lifting motor, and the other end of the main shaft is provided with a brake tapered body and a thrust supporting base; one end of the brake tapered body is pressed on the thrust supporting base through a thrust bearing, one side of the brake tapered body is provided with a brake circular cone coaxial with the brake tapered body, and a dual-effect hydraulic cylinder coaxial with the main shaft is hinged to one end of the brake circular cone through a pin shaft; and the outer side of the brake circular cone is provided with a guiding plate matched with a sliding groove in a ship body. According to the pile leg locking device provided by the invention, through thrust and friction force provided by a hydraulic system, the pile leg of an ocean platform stops moving and is locked, and the pile leg locking device has the advantages of being large in bearing load, simple in structure, stable in transmission, safe in property, reliable in control and the like.
Description
technical field [0001] The invention relates to a leg locking device, in particular to a leg locking device of a self-elevating ocean engineering platform and a locking method thereof, which is used for locking the legs of a jack-up ocean engineering platform, and belongs to ocean engineering technology field. Background technique [0002] With the increasing demand for oil energy in the global market and the continuous depletion of land oil energy, countries around the world have shifted their oil exploration from traditional land to oceans rich in oil and gas resources. Jack-up drilling platforms have always been the mainstream equipment for offshore oil exploitation in various countries because of their advantages such as strong positioning ability, long service life, low cost and high reliability. The locking device that can realize the locking of the platform legs in the drilling platform is one of the key components of the whole platform, and it is the equipment used ...
