Desenvolvimento de equipamento móvel para manipulação de artefatos perigosos

Abstract

Introduction: In recent decades, the concern with the safety of professionals who work in high risk functions has increased considerably, since some cases of accidents involving explosions bombs, terrorist attacks and civil wars throughout the world. Objective: from the need for security and stability more cleared on the transport of dangerous artifacts, was idealized a telescopic arm mounted and with motorized linkage, which allows for better accuracy in the capture of objects and greater protection of the operator. Methodology: The equipment idealized account with a mobile stand with casters for the loading of the arm, in addition to Rotary Actuator (which includes the motor, reducer and brake), Battery, servo drive, device driver and the ballistic shield. The drawings of the components do not exist on the market were produced by means of CAD and the necessary calculations were obtained from the literature and in the manual of the components. Results: It was found that the unit has adequate conditions of static stability, ensuring its not tipping. There was a large discrepancy in relation to the reactions of support between front and rear wheels, so that the front reaction was much more pronounced. However, an external force to the system can cause the suspension of the rear wheel, if there is an oversight on the intensity and location of your application. Conclusion: By means of the information submitted, it could be concluded that the tele handler mounted is a viable alternative to stabilize the movement of the artifact, providing greater security to the user. It is important to emphasize that this work is a pioneer in the creation of this equipment, with a few references in literature on this theme.
