Abstract
El presente informe de tesis se redactó con el objetivo de dar a conocer la realización del
diseño y la fabricación de un dispositivo instalador de calibradores para medir el espesor del
concreto lanzado a las paredes de los caminos dentro de una mina subterránea. La
investigación está motivada de la necesidad de las empresas de minería subterránea y
contratistas que trabajan en sostenimiento de realizar la verificación del espesor de las
paredes de concreto de manera más eficiente, segura y económica, reduciendo los incidentes
y accidentes asociados a la caída de banco y concreto lanzado, riesgos inherentes a esta
actividad.
La principal interrogante de esta investigación es: ¿Cuáles son los beneficios para las
empresas contratistas y las unidades mineras al implementar un dispositivo que instale clavos
calibradores en las paredes de concreto dentro de los túneles? Como respuesta a esta
interrogante se propone un dispositivo que se acopla en la punta del brazo de uno de los
equipos más utilizados para la labor de lanzado de concreto que al tener estas características
se llama shotcrete, específicamente el ROBOT SPM4210 de la marca Putzmeister. El diseño
del dispositivo considera el entorno de trabajo, la facilidad de uso, la elección de materiales
y la resistencia al entorno agresivo, resultando en un dispositivo liviano, fácilmente
transportable, económico y eficiente para su aplicación.
This thesis aims to design and manufacture a calibrator installer device for measuring the thickness of sprayed concrete on the walls of underground mine tunnels. The research stems from the need of mining companies and contractors to verify the thickness of concrete walls efficiently, safely, and economically, thereby reducing incidents and accidents related to the fall of bench and sprayed concrete—common risks in this activity. The primary question addressed in this research is: What are the benefits for contracting companies and mining units in implementing a device that installs calibrator nails on the concrete walls within tunnels? In response to this question, a device is proposed that attaches to the tip of the arm of one of the most widely used equipment for concrete spraying, known as shotcrete, specifically the Putzmeister ROBOT SPM4210. The device's design considers the working environment, ease of use, material selection, and resistance to aggressive surroundings, resulting in a lightweight, easily transportable, cost-effective, and efficient device for its application.
