AI Technical Summary
In the existing technology, the safety testing and joint commissioning technology of the super-large hydraulic cylinder of the pile frame of ultra-large ships is not perfect. There are problems such as incomplete verification of structural safety and reliability, pressure is prone to imbalance, low pressure of a single hydraulic cylinder can lead to overpressure, the main hydraulic cylinder is prone to jamming and scraping during the replacement process, and the joint bearing is difficult to align, resulting in low operation efficiency and safety hazards.
The system employs a main hydraulic cylinder system, an auxiliary hydraulic cylinder system, a pressure monitoring module, an alignment auxiliary module, and a control module. Through graded loading and real-time monitoring, combined with the joint bearing adjusting ring and the pin alignment adjusting block, the winding change slide is optimized to achieve comprehensive safety testing, stable commissioning process, and high efficiency in winding change operation.
It achieved comprehensive coverage of safety tests, stable pressure during the joint commissioning process, and efficient and smooth winch replacement operation. It solved the technical problem of incomplete verification of the structural strength and sealing performance of the ultra-large hydraulic cylinder system, avoided pressure imbalance and jamming/scratching problems, and improved operational safety and efficiency.
