海洋平台吊机溜钩故障分析及处置案例

Fault Analysis and Disposal Case of Offshore Crane Slip Hook

溜钩是指吊机起吊重物过程中,将主钩滚筒操纵杆置于中位后,吊钩自动下降的故障。吊机滚筒出现溜钩故障会造成所吊物体难以就位,严重时可能出现安全事故。因此,以中油海7平台吊机为例,根据滚筒液压系统工作原理,对海洋钻井平台吊机溜钩故障进行分析,并提出检修方法。

Sliding hook refers to the failure of the hook automatically lowering after the main hook roller lever is placed in the neutral position during the hoisting process.The hook slipping failure of the hoist drum will make it difficult to place the hoisted objects,and safety accidents may occur in serious cases.Therefore,taking the CNOOC 7 platform crane as an example,according to the working principle of the drum hydraulic system,the failure of the hook slipping of the offshore drilling platform crane is analyzed and the maintenance method is proposed.
