Embodiment Construction

[0018] As shown in Figure 1, it includes: two cartridge check valves V2, V5, four cartridge relief valves V1, V3, V4, V6, a sequence valve V9, a proportional relief valve V8, a Proportional throttle valve V13, and four one-way valves V7, V10, V11, V12; the connection relationship is as follows:

[0019] 1. The oil inlets of the first and second plug-in check valves V2 and V5 are connected to the pressure oil port of the pumping station, and the oil outlet of the first plug-in check valve V2 is connected to the port of the left traverse hydraulic motor. The B oil port is connected, the oil outlet of the second cartridge check valve V5 is connected with the A oil port of the right traverse hydraulic motor, and the control oil inlet ports of the first and second cartridge check valves V2 and V5 are connected. X is connected to the oil outlets of the first, second and third check valves V10, V11 and V12, and the control oil return port Y of the first and second cartridge check val...

Abstract

A hydraulic control system for moving the bow of dredger transversely is composed of two one-way valves, four overflow valves, one sequence valve, one proportional overflow valve, one proportional throttle valve and four check valves. Its different oil ports are respectively connected to the oil ports of hydraulic motor according to invented logic. Its advantages are adjustable accurate speed, high safety and high anti-interference power.

Description

technical field [0001] The invention relates to a hydraulic control system characterized by electro-hydraulic control technology, which is a hydraulic control system for dredger bow lateral movement. Background technique [0002] In the field of background technology, the dredging of large rivers and lakes mostly uses hinged suction or bucket wheel dredgers. The former is suitable for softer soils, and the latter is suitable for harder soils. The reamer or bucket wheel head stirs up the mud to be sucked from the bottom of the water, and then the mud is transported to the designated place, and the mud is evenly sucked from the bottom of the determined water area, a hydraulic system is required to drive the dredger, and the bow is required to be convenient. , Accurately move the bow left and right without being affected by changes in external conditions, so as to expand the working surface of a voyage as much as possible and improve the dredging efficie...
