Abstract

The invention relates to the technical field of marine cranes, in particular to a marine crane hydraulic control system with good heat dissipation performance. A lifting system involves an oil tank, avariable pump, a first overflow valve, a second overflow valve, a third overflow valve, a two-position two-way electromagnetic valve, a throttling valve, a cooler, a three-position four-way manual reversing valve and a hydraulic motor; and a braking system involves a metering pump, a fourth overflow valve, a two-position three-way manual reversing valve and a brake cylinder. Ascending and descending of the marine crane can be realized through the lifting system, the marine crane can be braked through the brake system, so that the operation safety of the marine crane is ensured; and meanwhile,the heat dissipation performance of the system is good, and thus the system can operate stably for a long time.

Description

technical field [0001] The invention relates to the technical field of marine cranes, in particular to a hydraulic control system of a marine crane with good heat dissipation performance. Background technique [0002] The marine crane is an important lifting equipment provided by the ship. Its application is of great significance to the development of my country's ocean shipping industry, the development of marine resources and the maintenance of marine rights and interests. The reliability and work efficiency of open water barge and hoisting of materials and spare parts are of great significance for shortening port stops, speeding up ship turnover, and reducing transportation costs. However, the existing marine crane hydraulic control system has poor heat dissipation effect. Contents of the invention [0003] The object of the present invention is to provide a hydraulic control system for a marine crane with good heat dissipation performance and stable operation. [0004...
