Embodiment Construction

[0027] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0028] The basic idea of ​​the present invention is: through two reels and two lifting devices, respectively connect two loads, use the gravity of one of the loads to fully offset or partially offset the gravity of the other load to achieve mutual balance, so as to realize The effect of energy saving consumption. Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in further detail:

[0029] like figure 1 As shown, a specific embodiment of the energy-saving system of the present invention is shown, including: a pull rope 100 , a first reel 200 , a second reel 300 , a first lifting device 400 and a second lifting device 500 . Wherein, the s...

Abstract

The invention discloses an energy saving system and a crane thereof. The energy saving system comprises a stay cord, a first winding drum, a second winding drum, a first lifting device and a second lifting device, wherein the beginning end of the stay cord is fixed; the stay cord sequentially surrounds the first winding drum, the first lifting device, the second winding drum and the second lifting device; and the tail end of the stay cord is fixed. According to the energy saving system, a carried object A on the first lifting device and a carried object B on the second lifting device can be controlled to lift and descend through the relative speed of the first winding drum and the second winding drum, so that the gravitational potential energies of the carried object A and the carried object B are mutually cancelled, the carried object A and the carried object B keep mutual balanced without an additional balancing weight, and the effects of energy conservation and consumption reduction are reached.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to an energy-saving system and a crane thereof. Background technique [0002] At present, cranes are generally used to vertically lift and carry heavy objects within a certain range. Due to their heavy load and easy operation, they have attracted more and more attention. However, cranes generally do not have energy-saving systems, resulting in higher average fuel consumption and increased transportation costs. Or configure an independent counterweight. When the load of the crane is lowered, the upwardly lifted counterweight stores the gravitational potential energy, so that when the load is lifted, the previously stored gravitational potential energy is released through the lowered counterweight to reduce the load. The driving force required for material lifting can achieve the effect of saving energy and reducing consumption. However, configuring an independent counterweight ...
