Environment protection hydraulic auxilary power system of hoisting machinery

Abstract

An environment protection type energy-saving hydraulic auxiliary power system for the hoisting machines (hoist, winder, elevator, fork truck, etc) is composed of hydraulic power system, hydraulic energy accumulator, hydraulic channel controller and timing power controller. It features that when the cargo is lifting, the hydraulic energy in hydraulic energy accumulator is used for boosting, and when the cargo is staying in sky, and its potential energy is converted to hydraulic energy and then stored in accumulator.

Description

technical field [0001] The invention relates to an environmentally friendly and energy-saving hydraulic auxiliary power system for lifting machinery, especially for lifting and lifting machinery such as cranes, winches, lifts, elevators, forklifts, etc., belonging to the field of operation and transportation, and lifting and lifting machinery . Background technique [0002] When engine-powered cranes, hoists, lifts, elevators, forklifts, etc. are working, the initial stage of cargo lifting (from stationary to rising movement) requires more power and energy, which often makes the engine work at overload, resulting in increased fuel consumption, With the increase of black smoke emission and pollution emission, a certain amount of power and energy is required in the placement stage (from static to descending movement) after the cargo is lifted to overcome the free fall motion caused by the potential energy of the cargo, control the descending speed and maintain a stable placeme...
