The invention relates to a double-portal folding and unfolding device and an operation method thereof. The double-portal folding and unfolding device comprises a moon pool, a portal device, a bracket lifting device and a deck opening and closing device. The moon pool is mounted at the stern of a hull; the deck opening and closing device is mounted on the hull at the upper part of the moon pool ; the portal device is mounted in the moon pool area; the bracket lifting device is installed on the portal frame device and used for lifting a submersible which enters autonomously to the position above the deck of the hull; and the portal device can swing towards the interior of the hull, the bracket lifting device and the submersible are swung inwards into the hull together, and folding and unfolding operation of the submersible is achieved. Automatic operation of the submersible from underwater to the ship deck or from the ship deck to the water surface is achieved, the operation efficiency and safety and reliability are greatly improved, the lifting winch has the advantages of being large in load capacity, light in self weight and small in base load, the lifting winch is provided with an active wave compensation system, and laying and recycling operation of the submersible under the high sea condition can be achieved.

    本发明涉及一种双门架收放装置及其作业方法,包括月池、门架装置、托架起升装置、开闭甲板装置;月池安装在船体艉部;开闭甲板装置安装在月池上部船体上;门架装置安装在所述月池区域内;托架起升装置安装在门架装置上,用于将自主进入的潜水器起升至船体甲板以上;门架装置能向船体内摆动,将托架起升装置和潜水器一起内摆至船体内,实现潜水器的收放作业。本发明实现了潜水器从水下至船体甲板或者船体甲板至水面的自动化作业,大大提高了作业效率和安全可靠性,并具有载重量大、自重轻和底座载荷小的特点,起升绞车配置主动波浪补偿系统,可以实现潜水器高海况下的布放回收作业。
