The invention discloses a synchronous mechanical locking mechanism, which belongs to the technical field of rapid recovery of offshore operation helicopters, and comprises a support plate, a locking pin, a pin shaft, a triangular sliding block, a first pin, a second pin, a fixed support plate, a long connecting rod, a tension spring, a tension spring screw, a detection assembly, an unlocking hydraulic cylinder and a limiting assembly. When the rapid mooring device normally operates, the multiple locking pins are in a retracted state under the action of the unlocking hydraulic cylinder, and the mechanical claw can move within the working range; when the rapid mooring device encounters emergency situations such as power supply faults, overload and chain breakage, the multiple locking pins synchronously stretch out under the action of the long connecting rod and the tension spring, and large-range transverse mechanical locking is conducted on the mechanical claw. The synchronous mechanical locking mechanism disclosed by the invention is high in safety, high in reliability and compact in structure, and can guarantee the safety of the offshore operation helicopter in the mooring and traction processes.

    本发明公开了一种同步机械锁止机构,属于海上作业直升机快速回收技术领域,包括支撑板、锁止销、销轴、三角滑块、第一销钉、第二销钉、固定支板、长连杆、拉簧、拉簧螺钉、检测组件、解锁液压缸和限位组件。快速系留装置正常运行时,若干个锁止销在解锁液压缸的作用下处于缩回状态,机械爪可在工作范围内运动;当快速系留装置遇到供电故障、超载、链条断裂等紧急情况时,若干个锁止销在长连杆和拉簧的作用下同步伸出,对机械爪进行大范围横向机械锁止。本发明公开的一种同步机械锁止机构安全性高、可靠性高、结构紧凑,能够保障海上作业直升机在系留和牵引过程中的安全。
