Shore bridge tilting-snagging integrated electric hydraulic control system and method

Abstract

The invention provides a shore bridge tilting-snagging integrated electric hydraulic control system and method. The system comprises a servo driver, an electric hydraulic drive module and a hydraulic cylinder; the electric hydraulic drive module comprises a servo motor, a hydraulic pump, a valve block and an integration oil tank, the servo motor is connected with the servo driver, one end face of the valve block is connected with the face, with a flange, of the servo motor, the other end face of the valve block and the face, with a flange, of the integration oil tank are connected and sealed, the hydraulic pump is arranged inside the integration oil tank, an input shaft of the hydraulic pump is connected with an output shaft of the servo motor through a coupler, and an oil port of the hydraulic pump is connected with the valve block through a hydraulic pipe; input / output hydraulic oil of the hydraulic pump passes through the valve block and then the hydraulic pump is separately connected with a first oil way block and a second oil way block by adopting hydraulic pipes, and the first oil way block and the second oil way block control the hydraulic cylinder. By changing the configuration of an existing system into a distributed integrated servo direct drive pump control hydraulic cylinder system, the defects that an existing system hydraulic pipelines is complex, energy dissipation is high, and fault handling is complex are overcome.

Description

technical field [0001] The invention relates to the field of port machinery quay cranes, and more specifically, relates to an electro-hydraulic control system and a control method for the quay crane tilting-storage integration. Background technique [0002] The quay crane in the container terminal is the core equipment in the loading and unloading system. The operating state of the equipment must be in a highly controllable state. Once an uncontrollable state occurs, it is very easy to cause the safety of the quay crane or even the loading and unloading ship. The tilting-storage system of the quay crane is a system to improve the operation efficiency and deal with the risk of hanging the warehouse urgently. Since both the tilting function and the hanging warehouse function are controlled by controlling the state of the main hoisting wire rope, the above two functions are combined Integrate in a unified system. [0003] The tilting-storage system is an essential system for t...
