Spring type suspension device for flexible vertical pipe

The utility model discloses a spring type suspension device for a flexible riser, which comprises a frame main body, a spring and a support arm, the support frame is fixed at the top end of a riser channel, the support arm is rotatably connected with the frame main body, the spring is arranged between the support arm and the frame main body, and a support platform is arranged on the support arm. The spring is compressed, when the end portion of the stand pipe extends out of the stand pipe, the spring rebounds, pushes the supporting arm to move inwards and enables the lower edge of the end portion of the stand pipe to be clamped on the supporting table, temporary supporting of the stand pipe is completed, in the process of fixing the stand pipe, a diver and an underwater robot are not needed for operation, construction efficiency is improved, and cost is reduced. 本实用新型公开了一种用于柔性立管的弹簧式悬挂装置，包括框架主体、弹簧及支撑臂，支撑框架固定于立管通道的顶端，支撑臂与框架主体转动连接，且两者之间设有弹簧，支撑臂上设有支撑台，当立管穿过框架主体的立管通孔时，弹簧被压缩，当立管端部伸出立管之外时，弹簧回弹，推动支撑臂向内移动，并使立管端部下边缘卡位于
