Improvements of the conveying machinery in thermal power plants: Case studies
Abstract
Bucket wheel boom (BWB) hoisting systems are the vital parts of the bucket wheel excavators (BWE). Failures of the mentioned systems are inevitably cause the BWE collapse followed by a very huge financial loss. This paper discusses the results of the investigation of the stress states of the BWB hoisting system connecting eye-plate. The redesign solution for the connecting eye-plate reconstruction has been chosen based on the comparative stress analysis of alternative solutions. The adopted solution satisfies all design restrictions and strength criterion. Besides that, the stress level is lower for ≈ 20 % compared to the original connecting eye-plate design. After installing the redesigned connecting eye-plates as well as during the operation of the BWE no failures have occurred. .
