The invention relates to a telescopic crane applied to an offshore pipe laying ship, and relates to the field of offshore pipe laying ships. The crane comprises a cabin body, at least two groups of supporting mechanisms, at least one group of driving mechanisms, a telescopic beam, a walking mechanism, an electric chain hoist and a control box, the supporting mechanism and the driving mechanism are connected with the inner top wall of the cabin body; the top of the telescopic beam is in sliding connection with the supporting mechanism, and the top of the telescopic beam is in transmission connection with the driving mechanism; the walking mechanism is movably connected with the bottom of the telescopic beam, and the electric chain hoist is connected with the bottom of the walking mechanism; the control box is installed on one side wall of the telescopic beam and electrically connected with the driving mechanism, the walking mechanism and the electric chain hoist. When ship pipe laying operation encounters severe sea conditions, the positioning floating ball can be safely and conveniently hoisted out of the cabin from the interior of the cabin to be connected with a pipeline and then thrown into the sea, and when continuous operation is needed, the positioning floating ball is hoisted into the cabin to continue operation.

    本申请关于一种应用于海上铺管船舶的伸缩式起重机,涉及海上铺管类船舶领域。该起重机包括包括舱体、至少两组支承机构、至少一组驱动机构、伸缩梁、行走机构、环链电动葫芦以及控制箱;支承机构以及驱动机构与舱体的内顶壁连接;伸缩梁的顶部与支承机构滑动连接,且伸缩梁的顶部与驱动机构传动连接;行走机构与伸缩梁的底部可移动连接,环链电动葫芦与行走机构的底部连接;控制箱安装于伸缩梁的一侧壁上,控制箱与驱动机构、行走机构以及环链电动葫芦电性连接。本申请实现了在船舶铺管作业遇到恶劣海况时可以使定位浮球安全方便的从舱体内吊到舱外与管道连接后扔入海里,并当需要继续作业时将定位浮球吊入船舱内继续作业。
