An automatic controller for steel pile trolley of cutter suction dredger

Abstract

The invention relates to an automatic controller for a cutter suction dredger steel pile trolley, which belongs to the technical field of automatic control of engineering ships. When the drawworks swings laterally to the sideline, press the traverse reverse operation button, and according to the control mode and the set step distance value of the steel pile trolley, the automatic controller of the steel pile trolley sends instructions to the steel pile trolley to control the steel pile trolley. The pile trolley automatically enters and closes or automatically retracts to zero position; it also includes one-key entry and one-key exit. In manual control mode, after pressing one key to enter and close automatically, the trolley automatically advances or retreats to set the stroke. The present invention realizes automatic dredging construction by automatically controlling the action of the steel pile trolley combined with the traverse winch and the bridge winch in different construction modes, which can greatly reduce the labor load of dredging operators and reduce the number of operations between different operators. The difference can improve construction quality, ensure equipment safety and reduce fuel consumption.

Description

technical field [0001] The invention belongs to the technical field of automatic control of engineering ships, and in particular relates to an automatic controller for a steel pile trolley of a cutter suction dredger. Background technique [0002] The steel pile trolley system is one of the important dredging equipment for large cutter suction dredgers. During the construction of cutter suction dredgers, the stepping and closing of steel piles and the reliability of the control will directly affect the accuracy of ship construction. speed and efficiency. After the 1990s, with the development of computer and network technology, the "whole ship integrated monitoring system" of dredgers was gradually applied, and operators could manually control the operation of steel pile trolleys remotely on the dredging console. However, there are large differences in the operation level and proficiency of dredging operators, which affect the construction accuracy of dredgers and the smooth...

Problems solved by technology

However, there are large differences in the operation level and proficiency of dredging operators, which affect the construction accuracy of dredgers and the smoothness of the connection between construction processes to varying degrees, resulting in problems such as uneven construction quality and efficiency and fuel consumption. Automatic dredging One of the control conditions is the need for automatic control of the steel pile trolley
