Abstract
Se trata de un percutor perforador mecánico-hidráulico de doble acción incluye un mandril tubular interno soportado en forma de enchufe dentro de una cubierta tubular externa. El mandril y la cubierta consisten cada una de una pluralidad de segmentos tubulares unidos, preferiblemente mediante conexiones internas roscadas. Los pistones de presión superiores e inferiores están dispuestos en forma deslizable dentro de la cubierta, cerrando respectivamente las cámaras hidráulicas superior e inferior que se encuentran sustancialmente selladas. El movimiento longitudinal del mandril engancha la boquilla, que a su vez traslada ya sea el pistón superior o el pistón inferior, dependiendo de la dirección del movimiento del mandril. Cuando se mueve uno de los pistones, aumenta la presión del fluido en la cámara hidráulica asociada, retardando el movimiento adicional del mandril, permitiendo que aumente la energía potencial en la cuerda perforada. La expansión de la boquilla está restringidahasta que el mandril alcanza un punto en particular en la cubierta, en dicho momento la boquilla se expande liberando el mandril para que choque rápidamente la superficie del martillo sobre el mismo con la superficie del yunque en la cubierta.It is a double-action mechanical-hydraulic hammer drill with an internal tubular mandrel supported in the form of a plug inside an external tubular cover. The mandrel and cover each consist of a plurality of joined tubular segments, preferably by internal threaded connections. The upper and lower pressure pistons are slidably arranged within the cover, respectively closing the upper and lower hydraulic chambers which are substantially sealed. The longitudinal movement of the mandrel engages the nozzle, which in turn translates either the upper piston or the lower piston, depending on the direction of movement of the mandrel. When one of the pistons is moved, the pressure of the fluid in the associated hydraulic chamber increases, retarding the additional movement of the mandrel, allowing the potential energy in the drilled chord to increase. The expansion of the nozzle is restricted until the mandrel reaches a particular point on the deck, at which time the nozzle expands releasing the mandrel so that the surface of the hammer thereon quickly collides with the surface of the anvil on the deck.
