Abstract

Patente de Invenção: "PROCESSO DE CONTROLE AUTOMáTICO PARA ABRIDOR HIDRáULICO DE FURO A CORRIDA". Processo de controle automático para um abridor de furo a corrida, para abrir um furo a corrida, conferindo impacto e rotação a uma unidade de broca que detém uma haste de perfuração e acionando a unidade de broca para frente e para trás por meio de um motor de acionamento hidraulicamente acionado, cujo processo compreende as etapas de detectar a carga de acionamento na forma de pressão hidráulica detectada, de interromper o acionamento, mas manter a rotação, quando a dita pressão detectada alcançar um valor determinado de limite superior, além do qual pode ocorrer o empenamento, e de resumir o acionamento, quando a dita pressão detectada cair para um valor determinado de limite inferior ou abaixo. A haste de perfuração da unidade de broca é impedida de ser empenada e atingida inutilmente, podendo ser obtidas uma operação de abertura de furo a corrida mais rápida e uma maior precisão da profundidade do furo a corrida. Assim, a operação remota se torna possível através da automação do trabalho de abertura de furo a corrida.
