Abstract

A hydraulic system with two guy winches with tension being independently adjusted comprises a hydraulic oil tank (1), an electric motor (2), a guy pump (3), a control pump (4), an oil supplement pump(5), a proportional direction valve (6), a shuttle valve (7), a cooler (8), a left reducing valve (13), a left electromagnetic reversing valve (14), a left balance valve (15), a left main overflow valve (16), a left pilot-operated type inverse proportional overflow valve (17), a left hydraulic motor (19), a left brake (20), a right reducing valve (21), a right electromagnetic reversing valve (22),a right balance valve (23), a right main overflow valve (24), a right pilot-operated type inverse proportional overflow valve (25), a right hydraulic motor (26) and a right brake (28). The cargo direction is maintained and adjusted by means of the left guy winch (29) and the right guy winch (30), the tension of the left guy winch (29) and the right guy winch (30) can be independently adjusted, operation is convenient and flexible, and the safety is high.

Description

technical field [0001] The invention relates to a hydraulic system, more specifically to a double-stable cable winch hydraulic system with independently adjustable tension, and belongs to the technical field of marine crane hydraulic control. Background technique [0002] The working environment of marine cranes is harsh, and they are greatly affected by ship tilting and wind load when lifting cargo. Therefore, it is often necessary to tie multiple guide ropes to the cargo to adjust the direction of the cargo during lifting and lowering the cargo to avoid collisions. When the rated load of the crane is small and the cargo is light, manpower can be used to control the lead rope; however, when the rated load of the crane is large and the cargo is heavy, the additional force when the cargo is deflected is much greater than that of manpower, and it is difficult for people to operate beside the cargo. There are certain risks. Contents of the invention [0003] The present inve...
