Abstract

A large-scale tool hoisting device for offshore electric power construction is provided. A steel cable retracted to winches is dried using the heat in the operating cabin, thereby preventing the steel cable from being in a wet state for a long time and being corroded by seawater. For different loads at the terminal of the steel cable, a transmission ratio between a drive wheel and a control wheel is changed through the sliding of the drive wheel. Without changing the rotational speed of the drive motor, the moving speed of the steel cable is effectively and correspondingly improved by reducing the pulling force of the steel cable, or a large pulling force can be provided for the steel cable by reducing the moving speed of the steel cable. The transmission ratio can be changed in the hoisting process.
