Overturning closed loop synchronous hydraulic system for erecting machine

Abstract

The invention relates to the field of erecting machines for construction equipment and provides an overturning closed loop synchronous hydraulic system for an erecting machine against the problem that two overturning oil cylinders of an existing erecting machine cannot be synchronized in the presence of large eccentric loading or inner leakage. The overturning closed loop synchronous hydraulic system comprises a detection system, a regulating system and a control system. The detection system and the regulating system are electrically connected with the control system, the control system is electrically connected with a power supply, the detection system is used for detecting the angles of the two oil cylinders corresponding to overturning arms of the erecting machine, the regulating system is used for regulating the angles of the overturning arms of the erecting machine, and the control system is used for analyzing detection results of the detection system and controlling the regulating system to work. According to the overturning closed loop synchronous hydraulic system for the erecting machine, real-time detection, real-time feedback, real-time control and real-time regulation are performed through a closed loop detection feedback regulation control system, so as to guarantee that the overturning arms of the erecting machine are synchronous in real time.

Description

technical field [0001] The invention belongs to the field of erectors for construction equipment, in particular to an overturning closed-loop synchronous hydraulic system of the erector. Background technique [0002] The erector is a kind of equipment used for concrete turnover and demoulding in the automatic concrete production line. The core components of the equipment are two oil cylinders for turnover. Previously, the two overturning cylinders were controlled by a synchronous motor to achieve synchronization. However, in the case of large eccentric loads in the two cylinders, or in the case of slight internal leakage in the hydraulic system, synchronization cannot be achieved and adjustments cannot be made. Contents of the invention [0003] The purpose of the present invention is to provide a closed-loop synchronous hydraulic system for vertical erectors in view of the inability to synchronize the two rotary oil cylinders of the existing vertical erectors under the c...
