Speed-limiting anchoring control system

Abstract

The invention provides a speed-limiting anchoring control system. A detection control device and an execution device are adopted and connected in a matched mode. The detection control device comprises proximity switches and a PLC unit, and the three proximity switches are connected with the PLC unit in a matched mode. The execution device comprises a servo pump starter, a servo pump, an electromagnetic valve, a servo oil cylinder and a speed-limiting anchoring control panel connected with the servo pump starter in a matched mode, the servo pump starter is connected with the servo pump in a matched mode, the servo pump is provided with a servo motor, connected with the electromagnetic valve in a matched mode and controlled by the electromagnetic valve, and the electromagnetic valve is connected with the servo oil cylinder in a matched mode. The three proximity switches form a detection part, one proximity switch is installed on an anchor chain plate transmission gear and used for detecting the anchor chain plate transmission gear, and the other two proximity switches are arranged on a brake belt and used for detecting loosening and closing of the brake belt to perform a position limiting function. When it is detected that the brake belt is loosened, the electromagnetic valve is closed, and the situation that the service life of a hydraulic unit is influenced due to a high-pressure load generated when the servo pump continuously pumps oil to the servo oil cylinder is avoided.
