A spud shoe and method of use thereof

Abstract

The invention provides a pile shoe and a using method thereof. The pile shoe comprises a guide rod, a base plate, a connecting rod, a piston cylinder, a supporting plate base and supporting plates. The piston cylinder comprises a piston, a piston rod and a reset spring. The top end of the reset spring is fixedly connected with the upper portion of the inner side of the piston cylinder. The bottom end of the reset spring is fixedly connected with the top face of the piston. The bottom face of the piston is fixedly connected with the top end of the piston rod. The piston cylinder is fixedly sealed in a pile leg. The bottom end of the piston rod is fixedly connected with the base plate and the guide rod in sequence. The base plate is in transmission connection with the connecting rod, the supporting plates and the supporting plate base in sequence. The supporting plate base is fixed to the pile leg. When the pile shoe is used for pile sinking, by means of seawater resistance, the base plate drives the connecting rod and then pushes the supporting plates on the periphery to be opened, the contact area between the pile leg and a seabed is increased, and the pile leg stability is improved; during pile pulling, the reset spring in the piston cylinder is utilized for pushing the piston, the piston rod and the base plate to move downwards together, the connecting rod drives the supporting plates to swing inwards, resistance is reduced, the structure is simple, and the brand new device is provided for a self-elevating platform.

Description

technical field [0001] The invention relates to the technical field of manufacturing marine engineering equipment, in particular to a spud can and a using method thereof. Background technique [0002] In recent years, with the increasing demand for energy, the development of offshore wind power has received increasing attention. The self-elevating wind power installation vessel is a widely used offshore wind power installation device, and its characteristic is to use the legs that can be lifted to realize the take-off and landing of the platform. In order to adapt to the soft seabed and increase the bearing capacity and stability of the wind power installation vessel, spud cans are usually provided at the lower part of the spud legs. The spud boots are generally added to the pile tips during the piling process. They are generally steel boots. The spud boots have two functions: one is to protect the pile tips; the other is to facilitate piling, because the spud boots are ver...
