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 mono-layer tube and bimetallic tube two kinds, and mono-layer tube primary structure covers one deck armored concrete outside monolayer steel pipe, and bimetallic tube primary structure is added with heat-insulation layer in the middle of two-layer steel pipe, and compound pipeline complex pipeline is referred to as by these two kinds of pipelines.
Subaqueous pipe saw is a kind of equipment adopting sawing mode to carry out compound pipeline complex pipeline cutting, and mainly contain diamond saw rope and two kinds, carbide alloy high strength saw blade by cutting tool difference, the former is called diamond-wire saw, latter weighlock blade pipe saw.Diamond-wire saw is applicable to cutting non-metal material, and cutting metal material efficiency is low, and guillotine type pipe saw is then contrary, and namely during cutting metal, efficiency is high, and cutting non-metal material efficiency is low.
By consulting both at home and abroad about diamond-wire saw and guillotine type pipe saw document, wherein representative documents [1-3] is as follows:
Documents 1: bend extra large rosy clouds, Zhao Jie, Zhang Lan; Lee's Peng. hydraulic brake blade pipe cutting machine designs. lathe and hydraulic pressure .2009 (03), describe the guillotine type pipe saw that E.H.wachs company of the U.S. 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 location, then clamps with chain, can realize accurately cutting, and cut surface is smooth, and operating efficiency is high.This pipe saw can change multiple saw blade, to adapt to steel pipe, and 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. Harbin Engineering University journal .2006 (03), propose cutting technology of underwater diamond wire saw, describe composition and the operation principle of underwater diamond rope saw, analyze the course of work of rope saw critical piece, calculate and determine the kinetic parameter of rope saw hydraulic system.Finally, cutting test has been carried out to offshore oilfield pipeline, relation between the Cutting Process parameter obtaining rope saw, can measure tension force and the radial cuts displacement of wire saw beading rope by test and monitoring system, according to the data point reuse cutting parameter measured and the whole cutting process of control.
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 existed at present, its difference is exactly make use of the stability that feed mechanism that triangle fixes strengthens work, the strainer of making a concerted effort can be measured, the floating drum of buoyancy can be changed under water, gear shift mode can be adopted to excise damaged submarine pipeline, the demand of various pipeline can be adapted to, rope saw cutting machine is had stronger universal, operability, simultaneously, owing to have employed the tensioning apparatus of force snesor, can regulate tensile force, there will not be the situation of saw rope over-tension, its security have also been obtained guarantee.
Can be drawn by documents: when document [1] guillotine type pipe saw cuts under water, artificial replacing saw blade is very difficult, therefore, saw blade can not be changed during usual imderwater cutting pipeline operations, only cut with hacksaw, therefore efficiency is high when cutting metal material, and cutting non-metal material ages rate is low, and underwater synthetic cutting efficiency is not high.Equally, document [2-3] only cuts with diamond rope saw, high in cutting non-metal material ages rate, and during cutting metal, efficiency is low, and equally, underwater synthetic cutting efficiency is not high yet.
