Abstract

A hydraulic control system for the locating unit of dredger is composed of two one-way valves, two shuttle valves, two overflow valves, electromagnetic diverter valve, two locking one-way valves, proportional throttle valve, and five logic one-way valves. It can control the hydraulic cylinder of locating pile to realize accurate location of dredger and adjustable moving speed, and can also protect the dredge when external force is too great.

Description

technical field [0001] The patent of the invention relates to a hydraulic control system characterized by electro-hydraulic control technology, which is a hydraulic control system for a positioning pile trolley of a dredger. Background technique [0002] In the field of background technology, the dredging of large rivers and lakes mostly uses suction or bucket wheel dredgers, the former is suitable for softer soils, and the latter is suitable for harder soils. The dredger uses a high-power mud pump to agitate the reamer or bucket wheel head to suck up the mud from the bottom of the water, and then transport the mud to the designated place. To suck the mud evenly from the bottom of a certain water area, a hydraulic system is needed to drive the dredger to facilitate the adjustment of the moving speed and precise positioning. However, the existing hydraulic control system of dredgers based on conventional plate valves has problems such as inconvenien...
