Embodiment 1

[0048] Such as Figure 1~6 As shown, a guide frame for salvage of a sunken ship includes a working platform 2 fixed on the outside of the mother ship 1, a drilling rig base 4 for installing a drilling rig 3 is installed on the working platform 2, and a drilling rig base 4 is installed on the drilling rig base 4. There is a pitch adjustment device 11 for adjusting the pitch angle of the drilling rig 3, and the outer edge of the working platform 2 is connected with a truss-type drill rod guide frame 5 for guiding the drill rod 301 of the drilling rig 3, and the truss-type drill The rod guide frame 5 includes a detachably connected platform hinged end 501, a straight pipe section 502, a bent pipe section 503 and a seabed anti-sinking fixed end 504 from top to bottom. The top of the platform hinged end 501 is connected to the working platform 1 connected, the seabed anti-sinking fixed end 504 is connected with the seabed 7;

Embodiment 2

[0058] A method for threading a large-diameter pocket jack for sunken ship salvage, comprising the following steps:

[0059] S1: Install the drilling rig 3 on the drilling rig base 4 of the guide frame used for salvaging sunken ships provided in Embodiment 1, and adjust the pitch angle of the drilling rig 3 through the pitch adjustment device 11;

[0060] S2: Start the drilling rig 3, so that the drill bit at the front end of the drill pipe of the drilling rig 3 is guided from one side of the sunken ship 10 to the The other side of the wreck 10;

[0061] S3: unload the drill bit from the drill pipe, and install the dragging reaming drill 12, and connect one end of the jack 13 to the dragging reaming drill 12 through the rotor mechanism 14;

[0062] S4: Pulling back the reaming drill bit 12 under the action of the drilling machine 3, the underwater positioning system and the truss-type drill pipe guide frame 5, from the other side of the sunken ship 10 according to the origina...

Abstract

The invention provides a guide frame for salvaging a sunken ship and application of a guide frame. The guide frame comprises a working platform fixed outside a ship board of a mother ship; a drillingmachine base for mounting a drilling machine is mounted on the working platform; a pitching adjusting device used for adjusting the pitching angle of the drilling machine is arranged on the drilling machine base; the outer edge of the working platform is connected with a truss type drill rod guide frame used for guiding the drill rod of the drilling machine; the truss type drill rod guide frame comprises a platform hinge end, a straight pipe section, a bent pipe section and a seabed anti-sinking fixing end which are detachably connected from top to bottom sequentially; the top of the platformhinge end is connected with the working platform; the seabed anti-sinking fixing end is connected with a seabed; and the guide frame for salvaging the sunken ship has an underwater positioning system.The guide frame can meet the requirements of different water depths; free heave compensation can be achieved with tide influences considered; and the dragging-back threading of a large-diameter jackcan be realized.

Description

technical field [0001] The invention relates to the technical field of salvage of sunken ships, in particular to a guide frame for salvage of sunken ships and its application. Background technique [0002] With the rapid development of marine economic activities, sunken ship salvage devices and their salvage methods are diverse, such as sealed tank pumping salvage, tank inflatable pumping water salvage, ship skid salvage, buoy salvage, floating crane salvage, pull jack double barge skid lift Salvage and other methods, the external forces of these methods are all transmitted to the hull through the bottom jack under the sunken ship. [0003] Among the existing cable-piercing operation technologies, the technology based on the horizontal directional drilling rig commonly used on land has been gradually applied in cable-piercing operations. However, when applying this technology underwater, there are still many problems, mainly as follows: [0004] (1) When the drilling rig i...
