Pile reinforcing device and method of self-elevating and self-propelling ship

Abstract

The invention discloses a pile reinforcing device and a method of a self-elevating and self-propelling ship. The pile reinforcing device comprises a spud leg and a fixing lug plate, wherein the fixing lug plate and a sliding framework are sleeved on the spud leg, the fixing lug plate is connected with a plurality of upper connecting rods through a plurality of rotating pairs, a plurality of limiting grooves are arranged on the fixing lug plate, the lower ends of the upper connecting rods are connected with lower connecting rods, the other ends of the lower connecting rods are connected on the sliding framework, and a chute is processed on the lower end of the spud leg. The method comprises the steps of: firstly, performing reconnaissance work, locating the final position of the sliding framework through a pin hole in the chute, then adjusting the height of a gasket below the sliding framework, finally connecting the sliding framework, the gasket and a dentiform block through bolts, firstly inserting the spud leg in the seabed soil, expanding the upper connecting rods until touching a locating pin pre-inserted in the pin hole to form a three-legged support structure, and executing a pile pulling action when the ship needs to leave a shaft position after finishing the work. The pile reinforcing device disclosed by the invention has the advantages of simple structure, convenience in operation, better maneuverability and capability of greatly improving the pile inserting efficiency and the ship stability.

Description

technical field

[0001] The invention relates to the technical field of manufacturing marine engineering equipment, in particular to a pile fixing device and method for a self-elevating self-propelled ship. Background technique

[0002] When the offshore mobile work vessel is erected on a relatively flat sea bed, there is generally no special treatment for the pile legs. However, when the bedrock of the seabed has a steep slope, if the general pile legs are used for positioning, it will The legs of the ship slipped, and sometimes the whole ship capsized seriously.

[0003] For piles with pile shoes (round or square), due to the larger size of the pile shoes (the linear size is 2-4 times the size of the pile body), the depth of pile insertion into the seabed is relatively shallow, which is conducive to pile extraction, but it is resistant to horizontal sliding At the same time, some spud shoes cannot be received in the hull after the piles are fully raised, which greatly in...
