AI Technical Summary
The existing needle beam trolley template drive cylinder has difficulty maintaining synchronization, multi-way valves are prone to oil circuit blockage and water hammer, cylinder leakage is difficult to detect in time, springs are prone to corrosion and stiffness reduction in liquid environment, slider connecting rod structure is not sealed, and connecting rod length affects rigidity.
Design a hydraulic cylinder drive control device for needle beam trolley templates. It adopts a synchronous oil circuit, buffer chamber, bridge-type connecting circuit and multiple sealing structure. Through the cooperation of slider and connecting rod, the hydraulic cylinder oil inlet is synchronized, the oil return is buffered, the leakage is detected in time and the seal is maintained, and the connecting rod is prevented from being impacted.
It achieves synchronization and sealing of the hydraulic cylinder drive, reduces oil circuit congestion and leakage, improves the reliability and service life of the equipment, and ensures the stability and safety of the template movement.
