The invention discloses a sunken ship salvage underwater tapping jack steel cable device, which belongs to the technical field of sunken ship salvage, and comprises an underwater tapping robot, the underwater tapping robot comprises a water spraying drill bit, a propelling device and an umbilical cord, the propelling device is arranged at the tail part of the water spraying drill bit, and the umbilical cord is connected with the propelling device and the water spraying drill bit. The tapping robot is designed to be capable of advancing by being attached to a ship bottom plate, and the robot advances by taking a transverse welding seam of the ship bottom plate or an adjacent tapping robot as a guide track; the head of the robot is provided with a replaceable tool bit and a high-pressure water spraying device, and a channel can be formed below a ship bottom plate; the robot only needs to overcome the resistance of the head during advancing, and the resistance of traditional tapping equipment is obviously increased along with increase of the tapping depth; the underwater channel tapped and drilled by the robot cannot collapse or be damaged due to the support of the upper ship bottom plate, the combination of the ship bottom plate and the mud surface is loose, the tapping efficiency is higher, and the rework rate is low; according to the device and the method, the threading operation of the large-water-depth shipwreck bottom-passing jack can be realized by adopting small equipment.
本发明公开了一种沉船打捞水下攻穿千斤钢缆装置,属于沉船打捞技术领域,包括水下攻穿机器人,水下攻穿机器人包括喷水钻头、推进装置和脐带,喷水钻头尾部设置推进装置,脐带连接推进装置和喷水钻头。本攻穿机器人设计为可贴合船底板前进,机器人根据船底板横向焊缝或相邻攻穿机器人作为导向轨迹前进;机器人头部设计有可更换刀头及高压喷水装置,可在船底板下形成通道;机器人行进只需克服头部的阻力,而传统攻穿设备随着攻钻深度的增加阻力显著增加;机器人攻钻的水下通道因为上部船底板的支撑不会塌方或损毁,且船底板与泥面的结合松散,攻穿效率更高,返工率低;本装置和方法采用小型设备即可实现大水深沉船过底千斤的穿引作业。
