Problems solved by technology

[0004]However, due to the large number of hydraulic motors, when the hydraulic oil flow rate is fixed, the turning speed is slow. When working and unloading, slow work is acceptable, but When the material is poured, the turning spreader cannot be reset quickly, which will affect the efficiency

Abstract

The invention discloses a hydraulic system for controlling a turnover lifting appliance, a turnover lifting appliance assembly and a crane, the hydraulic system for controlling the turnover lifting appliance comprises an oil inlet pipeline, a first hydraulic motor pipeline, a second hydraulic motor pipeline, a first middle pipeline, a second middle pipeline and an oil return pipeline; the oil outlet end of the oil inlet pipeline, the first end of the first hydraulic motor pipeline, the second end of the first hydraulic motor pipeline and the oil inlet end of the oil return pipeline are connected through a first electromagnetic valve, and the first end of the first middle pipeline communicates with the first end of the first hydraulic motor pipeline. The second end of the first middle pipeline is communicated with the second end of the second hydraulic motor pipeline, the first end of the second middle pipeline is communicated with the second end of the first hydraulic motor pipeline, and the second end of the second middle pipeline is communicated with the first end of the second hydraulic motor pipeline. And the on-off of the first middle pipeline and the on-off of the second middle pipeline are controlled by a second electromagnetic valve.

Description

technical field [0001] The invention relates to the technical field of hoisting devices, in particular to a hydraulic system for controlling a flipping spreader, a flipping spreader assembly and a crane. Background technique [0002] The forward-turning 360-degree turning spreader is an attachment that can turn the bulk material in the top-opening container forward and pour it out. [0003] When materials such as iron ore are loaded in the container, due to the high density and small volume of such materials, they only occupy a small part of the bottom volume of the container when loaded to the rated load of the container, so the load has a large eccentricity, and multiple groups are required. Only with the cooperation of the hydraulic motor can the container be turned over. [0004] However, due to the large number of hydraulic motors, when the hydraulic oil flow is fixed, the turning speed is slow. When the material is poured, the slow speed is acceptable, but when the ma...
