Abstract
La investigación buscó el diseño de un elevador móvil permanente con capacidad de carga de 500
kg para izaje. Por esta razón, lo investigación se consideró descriptiva ya que su objetivo
principal es recopilar datos e informaciones sobre las características, propiedades, aspectos o
dimensiones y clasificación de los objetos.
La metodología utilizada para el diseño parte de un proceso conceptual desde la ingeniería por
ende se planteó un estudio de un sistema mecánico ya que con esto observaremos si los
elementos son adecuados para trasmitir movimiento y potencia, además, con un estudio de
análisis estructural encontraremos los esfuerzos internos y las deformaciones que actúan en la
estructura, así mismo a partir de los esfuerzos principales es necesario considerar las relaciones
en resistencia y carga estática con el fin de tomar decisiones para la selección de material.
Luego se simuló utilizando el software CAD - CAE SolidWorks para su verificación.
El resultado fue un elevador magnético con una capacidad de carga máxima de 500 kg adaptable y
una altura de elevación de 2.5 m. Este sistema mecánico tiene un sub sistema de tijeras, propulsado
por un cilindro hidráulico telescópico para su ascenso y descenso. El sistema magnético, se basa en
el acoplamiento de dos estructuras para su desplazamiento lineal con ayuda de un motor con relación
de piñón cremallera aplicada sobre la plataforma superior, además cuenta con ruedas de guía para
distribuir la carga sobre la estructura.
Al dimensionar todo el mecanismo, se determinó factores de seguridad apropiados para la utilización
de perfiles estructurales convencionales como el acero ASTM A500 grado B, ASTM A572 y por
último el AISI 1018 Grado 65 que son utilizados para los elementos de conexión.
The research sought the design of a permanent mobile elevator with a load capacity of 500 kg for lifting. For this reason, the research was considered descriptive since its main objective is to collect data and information about the characteristics, properties, aspects or dimensions and classification of objects. The methodology used for the design is based on a conceptual process from engineering, therefore a study of a mechanical system was proposed since with this we will observe if the elements are adequate to transmit movement and power, in addition, with a structural analysis study we will find the internal forces and deformations that act on the structure, likewise from the main forces it is necessary to consider the relationships in resistance and static load in order to make decisions for the selection of material. It was then simulated using CAD - CAE SolidWorks software for verification. The result was a magnetic lift with an adaptable maximum load capacity of 500 kg and a lifting height of 2.5 m. This mechanical system has a scissor subsystem, propelled by a telescopic hydraulic cylinder for its ascent and descent. The magnetic system is based on the coupling of two structures for linear movement with the help of a motor with a rack and pinion ratio applied to the upper platform. It also has guide wheels to distribute the load on the structure. When sizing the entire mechanism, appropriate safety factors were determined for the use of conventional structural profiles such as ASTM A500 grade B steel, ASTM A572 and finally AISI 1018 Grade 65 that are used for the connection elements.
