Abstract

The invention discloses a marine electric pile driver based on a linear motor. The technical problems that an existing marine pile driver is poor in controllability and high in noise are solved. The marine electric pile driver based on the linear motor is composed of the linear motor, a variable-frequency controller, an energy storing device and other structural parts; the linear motor drives a pile hammer promoter to vertically move, the variable-frequency controller drives and controls the pile hammer promoter to move, and therefore control over parameters such as impact energy, impact frequency and travel is achieved; and especially implementing basic hardware conditions are provided for control over the parameters through the structural design of a linear motor stator. The marine electric pile driver based on the linear motor is simple in system structure, high in pile driving efficiency, good in controllability and low in failure rate and noise.

Description

technical field [0001] The invention relates to a pile driver on a piling ship, in particular to a marine electric pile driver based on a linear motor. Background technique [0002] The pile driver is a necessary heavy machinery for the foundation construction of construction projects. Its structure is composed of a pile hammer, a pile frame, a power system and ancillary devices. The impact force formed by the potential energy penetrates the pile into the ground, and the main performance parameter of the pile driver is the striking energy. The application occasions of pile drivers are divided into land construction and offshore engineering. The offshore pile driver is usually carried on a special piling ship, which requires a large amount of impact energy and is suitable for a high pile height. The existing offshore pile drivers are generally diesel hammer pile drivers. The main body of the diesel hammer pile driver is composed of a cylinder and a plunger. However, the di...
