Potential energy type crane with energy-saving counterweight system

Abstract

The invention discloses a potential energy type crane with an energy-saving counterweight system. The potential energy type crane comprises a metal framework, a cart travelling mechanism, a ladder platform, an electrical room, a cable drum, a hoisting mechanism, a driver cab, a wire rope, a pin shaft, a first pulley, a lifting tool, a second pulley and a third pulley. The cart travelling mechanism is located below the electrical room. The ladder platform, the electrical room and the cable drum are connected with the metal framework. The hoisting mechanism is located between the first pulley and the second pulley. The driver cab is located below the first pullet. One end of the wire rope is fixed with a main structure of the crane via the pin shaft, while the other end of the wire rope is connected with a counterweight system through the first pulley, the lifting tool, the second pulley and the third pulley. Innovatively, a set of counterweight system is embedded between the lifting tool and the hoisting and reeling system. According to the invention, the electric energy consumption of the crane during work can be reduced so as to avoid waste.

Description

technical field [0001] The invention relates to a crane, in particular to a potential energy type crane with an energy-saving counterweight system. Background technique [0002] In the design, manufacture and use of cranes in the past, the lifting capacity of the crane has been placed in the most important position, so that the importance of other performances has been underestimated. However, with the rise of energy prices and the improvement of people's energy-saving awareness, the energy-saving performance of cranes has received more and more attention. As an important material handling equipment, the energy consumption characteristics of the crane directly affect the economy of equipment use. In a traditional crane, the weight of the spreader as a non-effective load moves with the hoisted effective load. When moving upwards, the motor consumes electric energy to pull it; Most of the electric energy is burned by resistance heating to generate waste. Contents of the in...

AI Technical Summary

Problems solved by technology

In traditional cranes, the weight of the spreader as a non-effective working load moves together with the lifting effective working load. When moving upwards, the electric motor consumes electric energy to pull it; when moving downward, the electric motor generates electric energy. Most of the electric energy is burned through resistance heating, resulting in waste
