Abstract

The invention provides a hydraulic synchronous quick coupling mainly composed of a rotation mechanism, spring extending and retracting mechanisms, a plain flange, a blind flange, an electrical system,a hydraulic system and the like. The plain flange comprises a welded flange and a flange base body. The butt joint face of the welded flange is matched with the end face of a mechanism to be in buttjoint. The welded flange is provided with multiple flange support lugs used for being connected with clamping jaw assemblies. One end of each clamping jaw assembly is connected to the corresponding flange support lug. The other end of each clamping jaw assembly is connected with the corresponding spring extending and retracting mechanism. The other end of each spring extending and retracting mechanism is connected to the rotation mechanism. The rotation mechanism is arranged on the outer ring of the flange base body. The rotation mechanism is used for driving the spring extending and retracting mechanisms to extend or compress under the action of a power source, so that the clamping jaw assemblies clamp or disengage from the mechanism to be in butt joint. The hydraulic synchronous quick coupling adopts a single hydraulic cylinder to synchronously open all the connection clamping jaws, reliable separation between an LNG loading arm and a transport ship can be achieved, and the problemsthat pressing of the clamping jaws is asynchronous, the clamping jaws do not act, and pressing force is not large enough are solved.

Description

technical field [0001] The invention relates to the field of cryogenic fluid transportation, in particular to a hydraulic synchronous quick joint, in particular to a hydraulic synchronous quick joint for connecting a loading and unloading arm of a liquid ship to a manifold of a transport ship. Background technique [0002] The connector used to connect the manifold of the transport ship with the loading and unloading arm of the liquid ship uses a hydraulic motor or a hydraulic cylinder to drive the claws to achieve quick connection. The hydraulic motor drive adopts the form of one claw and one motor drive, that is, a single hydraulic motor drives a single claw. The connector needs at least three claws, so at least three sets of hydraulic motor drive mechanisms are required. The hydraulic claw control distributes the hydraulic oil to the small hydraulic valve group that controls each claw through the main hydraulic valve group, completing two series and parallel connections. ...
