Análisis de funcionamiento y rehabilitación de los elevadores de Ferrocarriles del Ecuador Empresa Pública Filial Sur-Estación Riobamba

Abstract

The Project has the aim to analyze the working and the further rehabilitation of the electro mechanics elevators of the “Ferrocarriles del Ecuador “company, in order to perform an analysis of efforts, to check the load to which each of the elevators may be subjected. The analysis to check the state, in which it was initially, each of the elevators was through an assessment matrix and non-destructive testing (END). In the case of the assessment matrix, it was identified each one of the anomalies and failures that will exist in the elements of the elevators. The non-destructive testing was using for the identification of discontinuities in the weld used. Realizing the analysis of functioning, it was proceeded to the rehabilitation of the elevators that consist in its maintenance, the substitution or the implementation of each one of the previously elements inspected. The digitization of the elevators was realized in SolidWorks, for later was imported to Ansys for the analysis of efforts. For checking the correct functioning of the electro mechanics elevators, a field test was carried out consisting of the elevation of a panoramic car that has a weight of 17 tons, as a result, it was obtained that each of the elevators had effective reliability. Performing the analysis of required operation, the elevators are rehabilitated corroborating that in the commissioning of the same, there is no problem whatsoever, In any case, in the case of a load of 60 tons, the safety factor will be 1,05; this load being the maximum that can support the 4 elevators. At the time of the elevation of a locomotive or a wagon it is advisable to lift them at a reasonable distance of 0,8 meters to observe if there is equilibrium in them.
