Ocean development has become an important component of the global new technology revolution, wherein ocean oil and gas development and offshore wind power development are one of the main contents of ocean engineering nowadays. The self-elevating platform is offshore movable drilling, living and service equipment, is the most used platform in world offshore oil exploration at present, has an important position in oil and gas exploration and development in sea areas due to strong positioning capability and good operation stability, and has higher and higher corresponding height along with the increasing capacity of offshore wind power units, so that the matching demand of the wind power platform is higher and higher.
In the platform structure, a pile leg is one of the most important parts of the platform, and the pile leg supports the whole weight of the platform and various external environmental forces, and besides the gravity load, the pile leg also needs to consider wind load, wave load, ocean current load and the like, so that high requirements on the strength, rigidity, buckling and fatigue of the pile leg are provided. In order to meet the requirements of use strength and support, the length of a pile leg used by the platform structure is basically more than 30m, the wall thickness for manufacturing the pile leg is large, the whole pile leg is formed by butting a plurality of pipes, holes need to be uniformly formed in the surface of the formed pile leg, the formed pile leg is too long and too heavy (the weight is about 30-40 tons) after the pipes are lengthened, the movement and the positioning are inconvenient, and the difficulty of forming the holes, particularly forming waist round holes (saddle holes) in the surface of the pipe body is large.
The current common cutting machine on the market is a full-automatic numerical control flame cutting machine, however, the device can only cut planes, because the automatic height-adjusting system of the device is not suitable for cambered surfaces and curved surfaces, including the current large-scale numerical control cutting on the market such as: gantry cutting, table cutting, profiling cutting machines and portable numerical control flame cutting machines are all used for cutting plane steel.
In order to solve the problem of hole opening, the existing numerical control pipeline intersecting line cutting machine for cutting the pipe in a professional mode can be used for cutting the waist circular hole, but the pipeline intersecting line cutting machine can only cut a small pipe, a chuck cannot meet the requirement of 30-40 tons of pipes, and the pipe is too long and too heavy to guarantee synchronous autorotation with a cutting device; the robot cuts the head opening mostly used for a single storage tank, the requirement is too high for the pipe with the length of about 30 meters, the cutting track with the length covering the length of the pipe needs to be customized, the cost is very expensive, in addition, the positioning requirement of the corresponding pipe fitting of the cutting track is very high, the positioning difficulty is high, the efficiency is low, and in consideration of the fact that the project (the whole platform or the pile leg) is built in different shipyards, the opening processing of the pipe can be carried out in an outsourced plant and a small group of stand shops, if one device is added or a special track is customized for one project, the cost is increased, and the corresponding labor is correspondingly increased; in addition, still can adopt the machine tooling trompil, but the machine tooling trompil needs equipment, and fixes a position fixed time long, efficiency is not high to making a round trip between different stations to the centre is transported very troublesome again.
