Energy-saving systems and anti-swing energy-saving crane provided with same

Abstract

The invention discloses energy-saving systems and an anti-swing energy-saving crane provided with the energy-saving systems. Each energy-saving system comprises a left energy-saving device and a right energy-saving which are symmetrical. Each energy-saving comprises a fixed pulley, a movable pulley and a balance weight, wherein the fixed pulley and an anti-swing sling system of the anti-swing crane are horizontally fixed, the movable pulley is connected with the balance weight, and a steel wire rope of the crane winds around the anti-swing sling system, the fixed pulley, the movable pulley and the balance weight sequentially and then is fixedly arranged above the crane. According to movement inertia, the balance weight and the movable pulley vertically move in the direction opposite to the movement direction of the anti-swing sling system through the steel wire rope. On the one hand, an included angle is formed between the steel wire rope on a sling and the horizontal plane, and the anti-swing function is achieved relying on the horizontal component of the balance weight; on the other hand, the balance weight can be used for balancing the weight of the sling, so that a hoisting mechanism only needs to act on a container instead of the sling, the energy performance of the crane is improved, and the effects of saving energy and reducing consumption are achieved.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to an energy-saving system and an anti-shake energy-saving crane equipped with the energy-saving system. Background technique [0002] At present, in the design, manufacture and use of cranes, more consideration is given to its lifting capacity and anti-sway capability. On the one hand, its lifting capacity and scope of application are continuously improved through structural improvement and material selection design; on the other hand, most of them are equipped with Equipped with an anti-sway device, it can effectively avoid a series of accidents such as collisions caused by the swinging back and forth of the spreader. [0003] 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 quality of the energy consum...

AI Technical Summary

Problems solved by technology

In traditional cranes, the spreader as a non-effective load moves together with the hoisted effective load. When moving upwards, the motor consumes electric energy to pull it, and most of the gravitational potential energy released when moving downwards can only be heated through resistance. burnt and wasted
