鲨鱼钳及拖销的使用步骤 | 鲨鱼钳和拖销

鲨鱼钳及拖销的使用步骤

当用纲丝绳进行拖曳时用钢丝绳时进行拖曳时

一般拖曳对象为船舶,或为浮式储油轮 FPSO 拖尾及用钢丝绳联接定位锚等作业。

1 启动电动机,使液压泵站工作。

2 按动机旁控制箱或驾驶室控制台的按扭(或操纵杆) ,升起鲨鱼钳,升起两条拖销, 并将钳口张开,动作完成后将操纵杆回复中位。把被拖曳的钢丝绳从两条拖销之间 卡入鲨鱼钳的钳口中,将钳口合上,这一步骤要尽快完成,因为海浪使钢丝绳及船 处于不稳定状态,很难将钢丝绳放在鲨鱼钳钳口的正确位置。
3 用卸扣或其他联接件将被拖曳的钢丝绳与船上拖缆机的钢丝绳联接好,并用拖缆 机将钢丝绳张紧,松开钳口,降下鲨鱼钳。
4 利用船或拖缆机进行拖曳时,拖销始终要在升起的位置,鲨鱼钳则降下甲板,使 船在转弯时钢丝绳依靠拖销限位,不损伤船舷及其他物品。
5 拖曳工作结束后,升起鲨鱼钳,夹住被拖曳的钢丝绳后,放松拖缆机的钢丝绳, 拆下两条钢丝绳之间的联接件,松开钳口,放掉被拖曳的钢丝绳。
6 将拖销与鲨鱼钳的盖板盖好,并将拖销与鲨鱼钳的升起部位涂满润滑脂,降下拖 销及鲨鱼钳,此时盖板应贴紧甲板,防止海水漏入舱内。

当用锚链进行拖曳时使用锚链时

一般用于协助平台的定位锚起抛锚

1 启动电动机,使液压泵站工作。

2 升起鲨鱼钳,将钳口更换成锚链钳口。

3 升起拖销,打开钳口。

4 将锚链从两条拖销之间放入鲨鱼钳的钳口内,并将钳口合上。卡紧锚链。

5 用卸扣或其他联接件将锚链与船上拖缆机的钢丝绳联接好,并将钢丝绳张紧。

6 松开鲨鱼钳的钳口,并降下鲨鱼钳至甲板下。

7 用船上拖缆机或船进行起锚工作,拖销始终在升起位置

8 起锚工作结束后,升起鲨鱼钳,夹住锚链,使锚链与拖缆机钢丝绳脱开,松开钳 口,放掉锚链。将拖销与鲨鱼钳的盖板盖好,并将拖销与鲨鱼钳的升起部位涂满润 滑脂,降下拖销及鲨鱼钳,此时盖板应贴紧甲板,防止海水漏入舱内。
9 关闭液压泵站。
