Problems solved by technology

[0004] There are relatively few introductions about internal pipe cutting technology at home and abroad. There is only an internal cutting arm carrying a high-pressure water nozzle, but its structure is not suitable for providing the necessary movement for traditional cold cutting methods.

Embodiment Construction

[0025] Below in conjunction with accompanying drawing, the present invention is described in more detail:

[0026] combine figure 1 and image 3 . The underwater pipeline internal cutting machine of the present invention mainly includes a box-type frame 1, a support device 2, a radial feed device 3, a cutting device 4, an underwater hydraulic control valve box and a detection system 5, and the like. It is placed in the pipe to be cut by the release device, and it is not limited by the position of the pipe during work. The support device 2, the drive part of the cutting device 4, the underwater hydraulic control valve box and the detection system 5 are installed in the box-type frame 1, and the radial feeding device 3 is driven by the cutting device 4. Part is connected with the box body.

[0027] Part 1 of the box-type frame is square in shape and adopts a split structure up and down, which is convenient for the assembly and maintenance of the whole machine. This part com...

Abstract

The invention provides a cutting machine in an underwater pipeline, which mainly comprises a tank type framework (1), a support device (2), a radial feeding device (3), a cutting device (4) and an underwater hydraulic control valve box and detection system (5), wherein driving parts of the support device (2) and the cutting device (4) and part of the underwater hydraulic control valve box and detection system (5) are mounted in the tank type framework (1), and the radial feeding device (3) is connected with the tank by the driving part of the cutting device (4). The invention has the advantages of reasonable structural design, and is convenient to operate, and can meet special requirements for cutting in underwater working environment and in steel pipes. The invention is used for cutting major-diameter steel pipes of offshore oil platform jackets, pile foundations and other underwater pipelines of which external cutting is restricted.

Description

technical field [0001] The invention relates to a cutting device, in particular to an underwater pipeline internal cutting device. Background technique [0002] Offshore oil occupies a very important position in the entire oil industry. With the development of the offshore oil industry, more and more oil production facilities are newly built in the operating sea area. With the exploitation of oil and the continuous depletion of resources, the service life of the platform is also decreasing will draw to a close. According to international conventions and relevant domestic laws and regulations, relevant facilities must be dismantled after oil and gas fields stop production. Since the first offshore platform was dismantled in the Gulf of Mexico in 1973, according to incomplete statistics, more than 2,000 platforms have been dismantled around the world. In our country, the dismantling of platforms is still a new project. According to statistics, in the next few years, there wi...
