ESTADO DE LA TÉCNICA STATE OF THE ART
Actualmente, en el rubro de la perforación de minería, construcción de pozos de agua y de pozos de geotermia, se utilizan diferentes medios para añadir barras a las columnas de perforación (collera) a fin de alcanzar la profundidad de pozo solicitada por un cliente, o la que sea necesaria para alcanzar un hallazgo geológico o hidrológico que se esté buscando. Los métodos que se usan actualmente para agregar barras a una collera, van desde la adición manual de barras, considerando el traslado de las barras desde un atril de barras o cama de barras por medios humanos, hasta medios neumáticos e hidráulicos automatizados mediante sensores y electrónica de control. Los medios más conocidos y utilizados para añadir o extraer barras de perforación en la industria del sondaje, son normalmente sistemas mecánicos, hidráulicos o neumáticos que pueden variar en forma y distribución de aditamentos, cuyos principios básicos de funcionamiento son: Currently, in the field of mining drilling, construction of water wells and geothermal wells, different means are used to add bars to the drill columns (collar) in order to reach the depth of the well requested by a client, or whatever is necessary to reach a geological or hydrological finding that is being sought. Currently used methods to add bars to a collar range from the manual addition of bars, considering the transfer of bars from a bar lectern or bar bed by human means, to pneumatic and hydraulic means automated by sensors and electronics. of control. The best known and most used means to add or extract drill rods in the drilling industry are normally mechanical, hydraulic or pneumatic systems that can vary in the shape and distribution of attachments, whose basic principles of operation are:
1. Adición asistida por medio mecánico de izaje, traslación, posicionamiento y ensamblaje de barras: Esta técnica es aplicada mediante la utilización de plumas y polipastos auxiliares (huinches), que funcionan de manera independiente o como aditamento de una máquina perforadora, generalmente asistida de manera manual, en el ensamblaje de la barra a la columna de barras de perforación. Este sistema tiene a favor, la simpleza de su funcionamiento y operación, además de su bajo costo de implementación, lo que significa, que la mayoría de las sondas de los diferentes tipos, lo traen implementado como parte del equipo. Sin embargo, los principales inconvenientes de la utilización de estos sistemas, es la exposición del personal asociado a la perforación, a riesgos que históricamente, han producido accidentes que van desde astricciones de extremidades por atrapamientos hasta muertes provocadas por caídas o descuelgues de barras durante la traslación o el ensamblaje. 1. Addition assisted by mechanical means of lifting, translation, positioning and assembly of bars: This technique is applied through the use of auxiliary booms and hoists (winches), which work independently or as an attachment to a drilling machine, generally assisted by manually, in the assembly of the rod to the column of drill rods. This system has in favor, the simplicity of its operation and operation, in addition to its low cost of implementation, which means that most of the probes of the different types, bring it implemented as part of the equipment. However, the main drawbacks of the use of these systems is the exposure of personnel associated with drilling, to risks that historically have produced accidents ranging from limb straining due to entrapments to deaths caused by falls or sags of bars during drilling. translation or assembly.
2. Adición asistida por medios hidráulicos controlados manualmente, para traslación, posicionamiento y ensamblaje de barras: Esta técnica es aplicada principalmente en máquinas de gran envergadura, generalmente utilizadas para la perforación de aire reverso y construcción de pozos de agua. Consiste principalmente en aditamentos o sistemas que mediante la utilización de energía motriz hidráulica, aplicada a pistones o cilindros hidráulicos, dan movimiento a mesas de traslación y ensamblaje o brazos articulados que mueven la barra desde su sitio en un atril, hasta la torre misma de la sonda, donde es añadida a la columna de perforación, por medios propios de la perforadora, por medios humanos mediante uso de llaves manuales para ensamblar o desensamblar barras o por medios mixtos de ensamblaje mediante posicionamiento de llaves y uso de torque proporcionado por la propia perforadora. Las principales ventajas de la utilización de estos sistemas, están relacionadas a la minimización de los riesgos asociados al levantamiento y traslado de barras desde el atril de barras hasta la torre de perforación. Sin embargo, los inconvenientes del uso de estos sistemas, se relacionan principalmente a la exposición del personal de la perforadora, a la manipulación de herramientas manuales que se posicionan en la torre para ajustar, apretar o desatornillar barras, lo que históricamente, ha producido graves accidentes que van desde lesiones menores, hasta la pérdida de extremidades por amputaciones traumáticas. Por otro lado, los costos de impiementación de estos sistemas, son considerablemente mayores a los costos de impiementación de medios mecánicos de adición de barras. Adición asistida por medios neumáticos controlados manualmente, para traslación, posicionamiento y ensamblaje de barras: Esta técnica, generalmente es utilizada para añadir barras en máquinas de perforación de mediana y gran envergadura, tales como sondas diamantinas de superficie y de minería subterránea, o perforadoras de aire convencional para banqueo. El método consiste generalmente en la utilización de energía neumática, como fuerza motriz, aplicada desde un acumulador, que entrega caudal de aire comprimido a articulaciones formadas por pistones o cilindros neumáticos, cuyo movimiento es controlado por electroválvulas manipuladas desde un panel de control de la propia sonda o por tele-comandos que permiten a un operador o asistente trasladar, posicionar y ensamblar la barra. Las ventajas de la utilización de medios neumáticos de adición de barras, se dan en relación a la minimización de los riesgos asociados a caídas de barras durante el izaje, traslación y ensamblaje de estas. Sin embargo, sus inconvenientes, están en relación al alto costo de su impiementación y al costo de su mantenimiento, que por su frecuencia, muchas veces significa que la disponibilidad de la perforadora, sea inferior a la que tienen sistemas hidráulicos de adición de barras. Adición automática de barras mediante fuerza motriz hidráulica o neumática accionada por control electrónico programable o robótico: Esta técnica es generalmente usada para añadir barras en equipos de perforación de minería, tanto en máquinas diamantinas de minería subterránea y rajo abierto, como en perforadoras de aire convencional para banqueo y muestreo de modelos geológicos de corto y mediano plazo, o también en perforadoras de aire convencional utilizadas para pozos de tronadura. La técnica consiste en la utilización de fuerza motriz neumática o hidráulica, administrada y accionada por medios de control electrónicos programados en PLC, celios o UPS, lo que permite añadir barras a una columna de barras, sin la más mínima intervención humana en el proceso. Las ventajas de estos sistemas, está relacionada a la alta eficiencia en el proceso de adición de barras, que suele ser mucho más rápida que en todos los otros sistemas existentes en el mercado, además minimiza por casi completo los riesgos relativos a exposición de trabajadores a caídas de barra durante el izaje, o movimientos descontrolados de barras durante su traslación o ensamblaje. Pero tiene como principales inconvenientes, el altísimo costo de su implementación, la minimización de la disponibilidad total del equipo debido a la periodicidad de su mantenimiento y la imposibilidad de ampliar los rangos de profundidad en la perforación, dadas sus configuraciones y seteos. 2. Addition assisted by manually controlled hydraulic means, for translation, positioning and assembly of bars: This technique is applied mainly in large-scale machines, generally used for reverse air drilling and construction of water wells. It consists mainly of attachments or systems that by using hydraulic motive energy, applied to hydraulic pistons or cylinders, give movement to translation and assembly tables or articulated arms that move the bar from its place on a lectern, to the probe tower itself, where it is added to the drill column, by means of the drill itself, by human means through the use of hand wrenches to assemble or disassemble bars or by mixed means of assembly by positioning the keys and using the torque provided by the drill itself. The main advantages of using these systems are related to minimizing the risks associated with lifting and transferring bars from the bar lectern to the drilling tower. However, the drawbacks of the use of these systems are mainly related to the exposure of the drilling personnel, to the manipulation of manual tools that are positioned in the tower to adjust, tighten or unscrew bars, which historically has produced serious Accidents ranging from minor injuries to the loss of limbs from traumatic amputations. On the other hand, the implementation costs of these systems are considerably higher than the implementation costs of mechanical means of adding bars. Addition assisted by manually controlled pneumatic means, for translation, positioning and assembly of bars: This technique is generally used to add bars in medium and large drilling machines, such as surface and underground mining diamond probes, or drilling rigs. conventional air for benching. The method generally consists of the use of pneumatic energy, as a driving force, applied from an accumulator, which delivers a flow of compressed air to joints formed by pistons or pneumatic cylinders, whose movement is controlled by solenoid valves manipulated from a control panel of the same. probe or by remote controls that allow an operator or assistant to move, position and assemble the bar. The advantages of the use of pneumatic means for adding bars are given in relation to minimizing the risks associated with falling bars during lifting, translation and assembly of these. However, its drawbacks are related to the high cost of its implementation and the cost of its maintenance, which due to its frequency, often means that the availability of the drilling machine is lower than that of hydraulic systems for adding bars. Automatic addition of bars by means of hydraulic or pneumatic driving force actuated by programmable or robotic electronic control: This technique is generally used to add bars in mining drilling equipment, both in diamond mining underground and open pit machines, as well as in conventional air drills. for banking and sampling of short and medium term geological models, or also in conventional air drills used for blast holes. The technique consists of the use of pneumatic or hydraulic motive force, managed and actuated by electronic control means programmed in PLC, celios or UPS, which allows adding bars to a column of bars, without the slightest human intervention in the process. The advantages of these systems are related to the high efficiency in the process of adding bars, which is usually much faster than in all other systems on the market, Furthermore, it almost completely minimizes the risks related to the exposure of workers to falling bars during lifting, or uncontrolled movements of bars during their translation or assembly. But it has as main drawbacks, the very high cost of its implementation, the minimization of the total availability of the equipment due to the periodicity of its maintenance and the impossibility of expanding the depth ranges in the drilling, given its configurations and settings.
Los métodos utilizados actualmente para añadir barras a una collera de perforación, presentan inconvenientes en relación a exposición de personas a accidentes y o en relación a la discontinuidad en la adición de barras de perforación o en su defecto a altos costos de implementación y mantenimiento además de los asociados a la rigidez respecto a sus configuraciones tanto estructurales como de software. The methods currently used to add rods to a drill collar, present drawbacks in relation to exposure of people to accidents and in relation to the discontinuity in the addition of drilling rods or, failing that, high implementation and maintenance costs in addition to the associated with stiffness with respect to both their structural and software configurations.
Es por todo lo anterior, que se hace presente la necesidad de un sistema de adición de barras de perforación, que minimice la exposición de las personas a riesgo de accidentes durante el proceso de adición de barras, proporcione adición de barras automática y continua, con costos de implementación menores a los costos de sistemas automáticos hidráulicos o neumáticos, y con una configuración y aditamentos simples que garanticen bajos costos de mantenimiento y mayor disponibilidad de equipo. Las respuestas a estas necesidades están en un sistema que hasta hoy, no existía en el mercado, que utilizando magnetismo y electromagnetismo como fuerza de sujeción de barras permite trasladarlas y posicionarlas en la torre de perforación, de manera continua y sin intervención de trabajadores y controlada por un sistema simple de operación manual remota. It is because of all the above that the need for a drilling rod addition system is present, which minimizes the exposure of people to the risk of accidents during the rod addition process, provides automatic and continuous rod addition, with implementation costs lower than the costs of automatic hydraulic or pneumatic systems, and with a simple configuration and accessories that guarantee low maintenance costs and greater availability of equipment. The answers to these needs are in a system that until today did not exist on the market, which using magnetism and electromagnetism as a clamping force for the bars allows them to be moved and positioned in the drilling tower, continuously and without the intervention of workers and controlled. by a simple system of remote manual operation.
El sistema, consiste en dos subsistemas, el primero, en una correa dentada con imanes distribuidos en toda su longitud y el segundo, formado por un par de brazos articulados integrados al cabezal de perforación, con electroimanes en sus extremos, los que toman la barra desde la correa y la posicionan en la torre de perforación. The system consists of two subsystems, the first, a toothed belt with magnets distributed throughout its length and the second, formed by a pair of articulated arms integrated to the drilling head, with electromagnets at their ends, which take the bar from the belt and position it on the derrick.
La solución propuesta en la presente solicitud, tiene por objetivo la minimización de riesgos de accidentes con daño a las personas, la optimización de la velocidad de adición de barras de perforación mediante un sistema continuo y la facilitación de la automatización del proceso a menores costos que los asociados a sistemas convencionales de manipulación y montaje de barras. The solution proposed in the present application has the objective of minimizing the risks of accidents with injury to people, optimizing the speed of adding drilling rods through a continuous system and facilitating the automation of the process at lower costs than those associated with conventional rod handling and assembly systems.
Las ventajas de un sistema automático de adición y extracción de barras de perforación, que usa magnetismo o electromagnetismo como fuerza de sujeción, además de las mencionadas comparativamente a los sistemas convencionales, son que el sistema es mucho más seguro, más barato y puede aplicarse como aditamento a todos los modelos de perforadoras, tanto de aire reverso, como aire convencional, diamantina y otros, agregando todas las ventajas comparativas a las diferentes perforadoras existentes en el mercado. The advantages of an automatic drilling rod addition and extraction system, which uses magnetism or electromagnetism as clamping force, in addition to those mentioned comparatively to conventional systems, are that the system is much safer, cheaper and can be applied as Addition to all models of drills, both reverse air, conventional air, diamond and others, adding all the comparative advantages to the different drills on the market.
