A kind of automatic controller of cutter speed of cutter suction dredger

Abstract

The invention relates to an automatic controller for the reamer speed of a cutter suction dredger, which belongs to the technical field of automatic control of engineering ships. The automatic reamer speed controller is composed of three sub-controllers, which are respectively: Controller, reamer speed and reamer torque ratio controller, reamer speed and traverse tension ratio controller; reamer speed control is controlled through the linkage control of each sub-controller; through the cutter suction dredger dredging control system and reamer speed The automatic controller automatically controls the speed of the reamer to ensure a balance between the amount of cutting and the suction of the pump, thereby realizing efficient automatic dredging. The invention controls the reamer speed through the linkage control of three sub-controllers according to different soil properties and different working conditions, so as to ensure a balance between the cutting volume and the pump suction volume, which can improve the working efficiency of the reamer and the excavation volume of the soil quality. , so as to achieve the purpose of increasing construction output.

Description

technical field [0001] The invention belongs to the technical field of automatic control of engineering ships, in particular to an automatic controller for cutter speed of a cutter suction dredger. Background technique [0002] After the 1990s, with the development of computer and network technology, the "whole ship integrated monitoring system" of dredgers has been gradually applied. Construction personnel can control the dredging equipment and monitor the dredging process through a remote workstation. This significantly improves the construction efficiency of dredgers, but the operation level and proficiency of dredging operators will greatly affect the construction output of dredgers. At the same time, there are also problems such as high labor intensity, low equipment safety, and relatively high fuel consumption. The core of the dredging process is to increase the construction output. At present, the relationship between lateral movement and cutting volume is still in ...

This significantly improves the construction efficiency of dredgers, but the operation level and proficiency of dredging operators will greatly affect the construction output of dredgers

At the same time, there are also problems such as high labor intensity, low equipment safety, and relatively high fuel consumption.

The core of the dredging process is to increase the construction output. At present, the relationship between lateral movement and cutting volume is still in the research and development process at home and abroad, especially for relatively hard and difficult-to-cut soils, and more effective reamer speeds are still being explored. , The control method of traverse pull force and reamer torque
