Análisis de la condición para el puente grúa del taller de fundición de la Facultad de Mecánica ESPOCH mediante el método de diagnóstico técnico

Abstract

The objective of this research work was to analyze the condition of the bridge crane of the Foundry at Mechanics Faculty, ESPOCH using the technical diagnosis method, revealing that the asset was in a state of "decay". For analysis and diagnosis; It was necessary to apply techniques such as: Thermographic Analysis, Vibrational Analysis, Laser Alignment, and sensory inspections in electrical and mechanical systems. Failures were evidenced in the motor bearings for horizontal movement, breakage of the stator anchor bolts, deterioration of the control pendant, control and power circuit conductors, poor condition of the transmission belts of the motor-reducers for horizontal and transverse movements. As a result of a pronounced misalignment of the pulleys of both motor-reducers. In the structural part, the driving and driven wheels presented disadvantages of poor machining in the concave part of the wheels, absence of the guide rail and runout of the driven wheel on the south side of the bridge, loss of the structure of the key and the keyway of the axle shaft. transmission of the aforementioned side, thus producing problems such as lack of synchronism between the south side and the north side of the bridge crane when moving transversely. It is concluded that through the application of different maintenance techniques based on condition, such as thermographic analysis, vibrational analysis, and laser alignment, and the use of the senses, it is possible to diagnose the technical state of the bridge crane which presented a condition of "Decay". Once this condition is known, a complementary project to is executed for the restoration and improvement of it. Carrying out the maintenance activities proposed in this work is essential to prevent the equipment from deteriorating.
