The invention provides a high-position winch safety self-locking and remote emergency hydraulic system and an operation method thereof. The system comprises a hydraulic oil tank (1), an electromotor (2), a lifting hydraulic pump (3), a control pump (4), a slippage pump (5), a manual pump (8), a proportional direction valve (10), a shuttle valve (12), a pressure reducing valve (13), a pilot operated directional control valve (14), a balance valve (15), a hydraulic motor (16), a brake (17), a pressure sensor (18), an oil filling check valve (19), a hydraulic control handle (24), a lifting powering-on solenoid directional valve (25) and a lifting powering-off solenoid directional valve (26). The operation method comprises the steps that a crane loses power when lifting goods or persons, and an arm frame is at a large angle or in a bad environment, and the hydraulic system performs remote emergency operation. The high-position winch safety self-locking and remote emergency hydraulic systemand the operation method thereof have the advantages that safe self-locking of a high-position winch is achieved, and the hydraulic system is safe and reliable; the remote emergency release can be achieved, and the security risks are avoided when the persons perform climbing operation.
Description
technical field [0001] The invention relates to a hydraulic system, more specifically to a high-position winch safety self-locking and remote emergency hydraulic system and its operating method, belonging to the technical field of marine crane hydraulic control. Background technique [0002] Maritime cranes have compact space requirements, and due to space constraints, the hoisting winches of some cranes can only be installed on the jib. When the crane is in the shelving state, the height of the hoisting winch is basically the same as the hydraulic oil tank; however, when the crane is working normally, when the angle with the horizontal direction gradually increases as the jib swings upward, the position of the hoisting winch will be significantly higher than that of the hydraulic oil tank. Hydraulic tank. When hoisting cargo, the crane often needs to keep the boom at a large angle. If the standby time is long, the operator will generally choose to stop; if it is restarted ...
