The Application Of Modularization Design Of Restoring Large-sized Outer Coating Pipe Twister

Rapid development of petroleum industry requires transportation trade bigger sized. Pipe restoring technique has been improved and restoring equipment has been renovated to ensure pipe transportation safe, effective and economy. In this article we aim at designing the outer coating pipe twister on the basis of the full understanding of the importance of restoring and we introduce the application of modularization to realize our design for mechanical products.Modularization, as more standardized one, is a comprehensive unit in the typification of product construction, the generalization of components, the sequence of parameter, modulization of feature value dimension and combination of assembly. Modular design is among up to down product designing progress, which includes two phase: the first one is to system "deconstruction" and to build modular construction series, the second one is to combine "modular construction" and to build products spectrum.At the beginning of the article, requested as what the outer coating pipe twister will perform, we compartmentalized the typical function of the machine and built modularization function tree of the machine, and then on the basis of the corresponding relationship between function and construction, we gave the whole modularization construction of the machine and discussed the possible construction of each function modular construction and the jointing form between each modular construction in detail. In the following chapters, we set up a 3-dimensional parameterized model of the outer coating pipe twister based on the object of the real pipe with (529 by 3D dimensional digital software UG, which verified the possibility of compartmentalization of modular construction structurally and the rationalization of the design for the jointing form. Whereafter, on the basis of analyzing the whole construction of the machine, we offer basic structure for each modular construction as well as changed structure so as to sum up the modularization spectrum of all these modular constructions. At last, the prospect of the technology of our machine has been discussed as well.In the application of modularization design on the outer coating pipe twister, the superiority of modularization design was confirmed. It was shown that the vitality of modularization design can be prospected...
