Abstract

The invention relates to a hydraulic driving system for controlling a turnover arm of a turnover table and the turnover table. The hydraulic driving system comprises an oil pump, a first oil cylinderand a second oil cylinder; a rodless cavity of the first oil cylinder communicates with the oil pump, and a rod cavity of the first oil cylinder, a rodless cavity of the second oil cylinder and a rodcavity of the second oil cylinder communicate with one another; the compression area of the rodless cavity of the first oil cylinder is equal to that of the rodless cavity of the second oil cylinder,and the compression area of the rod cavity of the first oil cylinder and the compression area of the rod cavity of the second oil cylinder are equal; and the compression area of the rodless cavity ofthe first oil cylinder is twice that of the rod cavity of the first oil cylinder. The connecting mode of the first oil cylinder and the second oil cylinder is changed, and the compression areas of therod cavity and rodless cavity of the first oil cylinder and the rod cavity and rodless cavity of the second oil cylinder are set, so that the synchronous action of the first oil cylinder and the second oil cylinder is guaranteed, a synchronous motor is not used, and therefore the cost of the hydraulic driving system is reduced.

Description

technical field [0001] The invention relates to hydraulic control technology, in particular to a hydraulic drive system for controlling the turning arm of the turning platform and the turning platform. Background technique [0002] The hydraulic drive system converts the pressure energy of the hydraulic oil into the mechanical energy of the actuator, so that the actuator acts to drive the equipment to perform the specified action. When the power required to drive the equipment to perform specified actions is large or one oil cylinder cannot meet the requirements of action stability, it is necessary to set up two oil cylinders that act synchronously. For example, the turning platform includes two turning arms, and each turning arm needs an oil cylinder to drive turning. Therefore, in order to ensure that each turning arm turns over synchronously, two oil cylinders need to act synchronously. [0003] In order to ensure the synchronous action of the two oil cylinders, two sync...
