Description
Technical field
What the present invention relates to is a kind of pipe cutting apparatus, specifically compound pipeline complex pipeline cutting operation auxiliary body.
Background technology
Pipeline under the ocean generally has two kinds of mono-layer tube and bimetallic tubes, and the mono-layer tube primary structure is that the monolayer steel pipe outside covers one deck armored concrete, and the bimetallic tube primary structure is to be added with heat-insulation layer, these two kinds of pipelines general designation compound pipeline complex pipelines in the middle of two-layer steel pipe.
The subaqueous pipe saw is a kind of equipment that adopts the sawing mode to carry out compound pipeline complex pipeline cutting, mainly contains two kinds, diamond saw rope and carbide alloy high strength saw blade by the cutting tool difference, and the former is called diamond-wire saw, and latter claims guillotine type pipe saw.Diamond-wire saw is fit to the cutting non-metal material, and cutting metal material efficient is low, and guillotine type pipe saw is opposite, and namely efficient is high during cutting metal, and the cutting non-metal material efficiency is low.
Domestic and international about diamond-wire saw and guillotine type pipe saw document by consulting, wherein representative documents [1-3] is as follows:
Documents 1: bend extra large rosy clouds, Zhao Jie, Zhang Lan; Lee's Peng. the design of hydraulic pressure guillotine type pipe cutting machine. lathe and hydraulic pressure .2009 (03), introduced the guillotine type pipe saw that U.S. E.H.wachs company produces, it cuts for level or vertical submarine pipeline, can cut different materials, the submarine pipeline of thickness.This guillotine type pipe saw can cut the pipeline of φ 50-610mm.This pipe saw utilizes V-block to carry out centering and locates, then clamps with chain, can realize accurately cutting, and cut surface is smooth, and operating efficiency is high.This pipe saw can be changed multiple saw blade, to adapt to steel pipe, the cutting of concrete and plastics etc.
Documents 2: Meng Qingxin, Cao Liwen, Wang Liquan, Zhang Zhonglin. the research of cutting technology of underwater diamond wire saw. the journal .2006 of Harbin Engineering University (03), cutting technology of underwater diamond wire saw has been proposed, introduce composition and the operation principle of underwater diamond rope saw, analyzed the course of work of rope saw critical piece, calculated and determined the kinetic parameter of rope saw hydraulic system.At last, offshore oilfield pipeline has been carried out cutting test, obtain the relation between the Cutting Process parameter of rope saw, by tension force and the radial cuts displacement that test and monitoring system can be measured wire saw beading rope, adjusted cutting parameter and the whole cutting process of control according to the data of measuring.
Contrast patent 3: Wang Liquan, Zhang Bo etc. a kind of underwater rope saw cutting machine (patent No. ZL200810209831.4) discloses a kind of underwater rope saw cutting machine, it comprises feed mechanism, is arranged on the clamping device of feed mechanism bottom, is arranged on the cutting mechanism on feed mechanism.the rope saw cutting machine of this invention is compared with the various rope saw cutting machines of present existence, its difference is exactly to have utilized the fixing feed mechanism of triangle to strengthen the stability of work, can measure the strainer of making a concerted effort, can change under water the floating drum of buoyancy, can adopt the damaged submarine pipeline of gear shift mode excision, the demand that can adapt to various pipelines, rope saw cutting machine is had stronger universal, operability, simultaneously, due to the tensioning apparatus that has adopted the power sensor, can regulate tensile force, the situation of saw rope over-tension can not appear, its security also is guaranteed.
Can be drawn by documents: when document [1] guillotine type pipe saw cuts under water, artificial replacing saw blade is very difficult, therefore, can not change saw blade when usually cutting pipeline operations under water, only cut with hacksaw, therefore efficient is high when cutting metal material, and efficient is low during the cutting non-metal material, and the underwater synthetic cutting efficiency is not high.Equally, document [2-3] only cuts with diamond rope saw, and efficient is high when the cutting non-metal material, and efficient is low, same during cutting metal, and the underwater synthetic cutting efficiency is not high yet.
