Embodiment Construction

[0012] Embodiments of the hoisting circuit integrated module of the marine crane hydraulic system of the present invention: as Figure 1-3 As shown, it includes a valve body integrated mounting seat 1 used to be connected in series between the two main oil circuits 8 of the system. The valve body integrated mounting seat 1 is a rectangular parallelepiped structure. On its left and right sides, the left oil inlet connector 2 and the right oil inlet connector 6 are respectively connected to the two serial interfaces; a flushing valve 3 is fixed on the upper end surface of the valve body integrated mounting seat 1, and the The throttle valve 4 and the electromagnetic reversing valve 5 arranged in sequence on the left and right are fixed on the front side of the valve body integrated mounting seat 1, and the flushing valve 3, the throttle valve 4 and the electromagnetic reversing valve 5 can all adopt existing technology. The structure of the control valve, wherein the flushing va...

Abstract

The invention discloses a hoisting loop integrated module of a ship crane hydraulic system. The hoisting loop integrated module comprises an integrated valve body installing base, a throttling valve, an electromagnetic reversing valve and a washing valve which are fixedly arranged on the integrated valve body installing base, two oil inlet joints and one oil return joint are connected with the integrated valve body installing base; the integrated valve body installing base is connected with a first oil path connected between the two oil inlet joints and used for sequentially serially connected the throttling valve and the electromagnetic reversing valve, a second oil path used for connecting the two oil inlet joints with two oil inlets of the washing valve in a one-to-one correspondence manner, and a third oil path used for connecting the oil return joint with an oil return hole of the washing valve. On one hand, the occupation space of a hoisting loop is greatly reduced, a large quantity of pipelines are prevented from being used for connection so that the cost is lowered and the convenience is brought to the maintenance; on the other hand, only three joints are required to be arranged in the whole hoisting loop, and thus the using quantity of the joints is reduced, and the probability of causing oil leakage is reduced.

Description

technical field [0001] The invention relates to a hydraulic circuit integrated module, in particular to a hoisting circuit integrated module of a marine crane hydraulic system. Background technique [0002] In the lifting circuit of the closed hydraulic system of the existing marine crane (also known as the crane), there are multiple control valves (flush valve, throttle valve, electromagnetic reversing valve), among which the throttle valve and the electromagnetic reversing valve The valves are sequentially connected in series between the two main oil circuits. The flushing valve has two oil inlets, one oil return port, and spool oil passages respectively connected to the two oil inlets for assembling the spool. Two of them The oil inlet is respectively connected with the two main oil circuits in one-to-one correspondence, and the oil return port is connected with the oil return tank. In this hoisting circuit, each control valve is independently installed on its own valve ...
