Abstract

The invention discloses a hydraulic synchronizer protection circuit and a hydraulic synchronizer with the hydraulic synchronizer protection circuit. The hydraulic synchronizer protection circuit comprises a detection signal processing module, a comparison module and a switch control module. The detection signal processing module is provided with a first detection signal input end and a second detection signal input end, the comparison module is provided with a calibration value signal input end, the comparison module is electrically connected with the output end of the detection signal processing module, the switch control module is provided with an external control signal input end, the switch control module is electrically connected with the output end of the comparison module, and the switch control module outputs a switch signal of a hydraulic valve. According to the hydraulic synchronizer protection circuit, the state information of hydraulic cylinders of different paths of the hydraulic synchronizer is collected, processed and compared, when the synchronization of the hydraulic cylinders of the different paths exceeds the limit, the work of the hydraulic valve is stopped, andthe hydraulic valve is prevented from being damaged due the load driven by the hydraulic synchronizer.

Description

technical field [0001] The invention relates to the technical field of synchronizing devices, in particular to a hydraulic synchronizing device protection circuit and a hydraulic synchronizing device. Background technique [0002] The hydraulic synchronization device is often used to drive large loads or large partial loads. In the hydraulic synchronization device, multiple hydraulic valves and other components are used to control the oil intake of multiple hydraulic cylinders, which can realize simultaneous lifting / lowering of multiple hydraulic cylinders. The hydraulic synchronization device in the prior art usually electrically connects the position sensor to the hydraulic cylinder, detects the position of the hydraulic cylinder and outputs the detected position data to the controller, and the controller can adjust the corresponding hydraulic cylinder according to the position data of each hydraulic cylinder. The hydraulic valve keeps the hydraulic cylinders driven synchr...
