Abstract

The invention relates to a double-cylinder synchronous erecting hydraulic system which comprises a hydraulic source, double cylinders, an electro-hydraulic reversing valve, a throttling nozzle, a first reversing valve and a second reversing valve, the flow direction of hydraulic oil is switched through the electro-hydraulic reversing valve, so that the erecting or lowering process of the double cylinders is achieved, and in the process, if the situation of slow ascending or slow descending occurs, the double cylinders can be erected or lowered. The first reversing valve and the second reversing valve can be switched, so that part of hydraulic oil enters the first erecting oil cylinder or the second erecting oil cylinder to be compensated, and the flow flowing into or flowing into the throttling nozzle is reduced; the pressure of the small cavity of the left erecting oil cylinder or the pressure of the small cavity of the right erecting oil cylinder changes relative to the pressure of the small cavity of the right erecting oil cylinder or the pressure of the small cavity of the left erecting oil cylinder, and therefore synchronous erecting or synchronous lowering of the double cylinders is achieved.

Description

technical field [0001] The present application relates to the field of hydraulics, in particular to a dual-cylinder synchronous erection hydraulic system. Background technique [0002] At present, the launching device adopts an erecting arm or an erecting frame to support the launch load, and an erecting oil cylinder is used to complete the erection of the erecting arm or the erecting frame. It is the core task of the hydraulic system to complete the erecting function of the erecting arm or erecting frame, and the index of erecting function is an important index requirement that the hydraulic system of the launching device needs to meet. If a single-cylinder erection scheme is adopted for a large-scale launch device, the erection cylinder is difficult to layout, the thrust is too large, and the upper and lower hinge fulcrums of the erection cylinder are partially stressed. In order to solve the above-mentioned difficulties, the erection of large-scale launching devices most...
