摘要：

In response to the problem of the existing pipeline repair equipment being cumbersome to operate, having large errors, and being unable to guarantee a successful cut and dock in one go, this paper carries out the structural design and experimental analysis of new type of pipeline repair equipment. The structural design of the new pipeline repair equipment has the technical advantages of accurately finding the center inside the pipeline, achieving laser alignment at a long distance and with high precision, and quickly marking lines. The structural design is further elaborated from three aspects: the establishment of the theoretical model, the calculation of the structural parameters, and the finite element analysis of the parameters of the key components. This paper believes that for two DN400 pipelines with non-overlapping axes and an axis inclination angle within 10°, when the connecting rod length is designed to be 190mm, the design of the key components conforms to the equal life design principle, and the maximum load received by the key components does not exceed the material yield limit. Experimental results demonstrate that, after familiarizing oneself with the installation and usage procedures of the new pipeline repair equipment, The equipment’s fixation work, long-distance alignment work and line drawing work can be completed within 5 minutes. and the error does not exceed 2mm. Both the marking lines time and the precision of the cutting butt joint meet field operation requirements. The findings of this paper can provide significant technical support for the design of long-distance pipeline repair equipment. © 2024, Politechnica University of Bucharest. All rights reserved.
