Antecedentes de la técnica Prior art
Por el estado de la técnica se sabe que la mayoría de las tolvas de izaje existentes poseen un sistema de ingeniería convencional que las accionan. Y están diseñadas para trabajos a campo libre. La técnica habitual es que las tolvas de izaje sean asistidas con un comando de apertura y cierre usando un sistema convencional, sea éste oleo-hidráulico, neumático, eléctrico y/o magnético. Lo que obliga a llevar ya sea mangueras y/o cables eléctricos para su accionamiento adosados durante su recorrido.  It is known from the state of the art that most existing lifting hoppers have a conventional engineering system that drives them. And they are designed for free field work. The usual technique is that the lifting hoppers be assisted with an opening and closing command using a conventional system, be it oil-hydraulic, pneumatic, electric and / or magnetic. What forces to carry either hoses and / or electrical cables for its operation attached to it during its journey.
Cabe anotar que las torres de lixiviación miden: 2 Mt. de diámetro x 10 Mt. de altura. Y tienen una lumbrera o entrada por la parte superior de la misma, la tolva de izaje debe entrar hasta el fondo de la misma. No se permite arrojar el material minero desde arriba, ya que rompería la geo- membrana del piso interior. It should be noted that leaching towers measure: 2 Mt. in diameter x 10 Mt. in height. And they have a port or entrance at the top of it, the lifting hopper must enter to the bottom of it. It is not allowed to throw the mining material from above, as it would break the interior floor's geo-membrane.
Por el estado de la técnica, las tolvas de izaje existentes en el mercado no cumplen los requisitos de trabajo en espacios confinados; SEGURIDAD MINERA no permíte la introducción de mangueras bajo presión de ningún tipo, ni cables eléctricos de mando en las torres de lixiviación. Due to the state of the art, the lifting hoppers on the market do not meet the work requirements in confined spaces; MINING SAFETY do not allow the introduction of hoses under pressure of any kind, nor electric control cables in the leaching towers.
Por considerarlo de ALTO RIESGO. Descripción de la invención Because it is considered HIGH RISK. Description of the invention
Como solución a los problemas antes mencionados se desarrolló la presente TOLVA DE IZAJE AUTO- ACCIONADA, caracterizada por: Una caja rectangular, construida en acero naval antl-abrasiva con dos caras laterales rectas y dos caras con caída trapezoidal para facilitar la salida del material minero, la cara posterior tiene a su vez un zócalo a 45° en la parte inferior para facilitar la salida del material minero. Y la cara delantera está constituida por una quijada móvil que recorre una curvatura de diseño. El fondo de la tolva tiene un zócalo a manera de refuerzo para evitar su deformación y el borde superior de la misma tiene una platina en todo el contorno de la caja también como refuerzo.  As a solution to the aforementioned problems, the present SELF-DRIVEN HOPPER HOPPER was developed, characterized by: A rectangular box, constructed in anti-abrasive naval steel with two straight side faces and two faces with trapezoidal drop to facilitate the exit of the mining material , the back side has a 45 ° socket at the bottom to facilitate the exit of the mining material. And the front face is constituted by a movable jaw that runs through a design curvature. The bottom of the hopper has a base as a reinforcement to prevent deformation and the upper edge of the hopper has a plate around the contour of the box also as reinforcement.
La parte interior de la tolva posee cuatro esquineros como refuerzo, uno en cada esquina de la parte superior de la caja de la tolva y uno en cada esquina de la quijada. La caja de la tolva y la quijada tienen cuatro soportes tipo phrotantes, donde articulan un extremo de los cuatro brazos de accionamiento. Dos van soldados en las caras laterales parte alta posterior de la tolva, uno en cada lado y dos van soldados en las caras laterales parte alta de la quijada, también uno en cada lado. Los cuatro brazos de accionamiento, van articulados por pares. Un brazo recto para la parte lateral posterior de la tolva y uno curvado para la parte del mismo lado de la quijada. El otro par de brazos van simétricamente al otro lado de la tolva y quijada respectivamente. Este accionamiento de los brazos es del tipo tijeral. La conformación de los brazos de accionamiento se encuentra reforzado con un tubo soldado en la parte superior para evitar su deformación. Un tubo de refuerzo para los brazos posteriores y un tubo de refuerzo para los brazos delanteros de la quijada. De esa manera se consigue el paralelismo de los brazos de accionamiento cuando la tolva se halle en funcionamiento. The inner part of the hopper has four corners as reinforcement, one in each corner of the upper part of the hopper box and one in each corner of the jaw. The hopper box and the jaw have four phrotant brackets, where they articulate one end of the four drive arms. Two are welded on the upper back side of the hopper, one on each side and two are welded on the upper side of the jaw, also one on each side. The four drive arms are articulated in pairs. A straight arm for the back side of the hopper and one curved for the side of the same side of the jaw. The other pair of arms go symmetrically to the other side of the hopper and jaw respectively. This arm drive is of the scissor type. The conformation of the drive arms is reinforced with a welded tube at the top to prevent deformation. A reinforcement tube for the rear arms and a reinforcement tube for the front arms of the jaw. This way, the parallelism of the drive arms is achieved when the hopper is in operation.
El borde inferior de la quijada y el borde delantero inferior de la tolva llevan una uña de engrampe de seguridad para evitar que la quijada se abra cuando la tolva esté suspendida.  The lower edge of the jaw and the lower front edge of the hopper carry a safety staple nail to prevent the jaw from opening when the hopper is suspended.
Esta uña guía es de forma triangular, con un ángulo recto y dos caras a 45°. Y va soldada una en el borde Inferior delantero de la caja de la tolva y la otra en el borde superior de la quijada, de tal manera que al cerrarse la quijada engrampa en la uña guía y las dos caras rectas se traban. This guide nail is triangular in shape, with a right angle and two faces at 45 °. And one is welded on the lower front edge of the hopper box and the other on the upper edge of the jaw, so that when the jaw is closed staples on the guide nail and the two straight faces are locked.
Mientras la tolva esté suspendida, los ángulos que tienen los brazos de accionamiento generan una componente de la fuerza que impide que la quijada se abra cuando la tolva se encuentre suspendida. While the hopper is suspended, the angles that the drive arms have generate a force component that prevents the jaw from opening when the hopper is suspended.
Cuatro estrobos de la misma medida son enganchados, uno en cada agujero de la parte superior de los brazos de accionamiento. Luego se procede a colocar un grillete para los dos estrobos del lado derecho y el otro grillete para los dos estrobos del lado izquierdo. Estos dos grilletes se colocan en el gancho del tecle eléctrico para su accionamiento. La presente invención funciona de la siguiente manera Four strobes of the same size are hooked, one in each hole of the upper part of the drive arms. Then we proceed to place a shackle for the two strobes on the right side and the other shackle for the two strobes on the left side. These two shackles are placed on the hook of the electric key for actuation. The present invention works as follows
La tolva de izaje auto-accionada ha sido diseñada para trabajar solo con los efectos de la gravedad y con un tecle eléctrico para su izaje y desplazamiento. Al posicionar la tolva en el piso para realizar la operación de carguío, esta debe encontrarse en posición semi-suspendida. The self-powered lifting hopper has been designed to work only with the effects of gravity and with an electric key for lifting and moving. When positioning the hopper on the floor to perform the loading operation, it must be in a semi-suspended position.
Es decir ios estrobos que accionan ios brazos de la tolva de izaje, deben encontrarse con una pequeña tensión o fuerza regulada por el tede eléctrico, esto para que la quijada se encuentre en su posición de cerrada y la uña de engrampe se halle conectada y presionada. That is to say, the strobes that actuate the arms of the lifting hopper must meet a small tension or force regulated by the electric tede, this so that the jaw is in its closed position and the engrampe nail is connected and pressed .
Se procede a la operación de carguío de la tolva con el material minero, colocando las rocas y/o piedras de mayor diámetro en la parte inferior y las de menor diámetro en la parte superior, finalmente la tierra y ta arena. La tolva de izaje auto-accionada debe ser cargada al 100 %, si se pone el 60 % esta no abre. The operation of loading the hopper with the mining material is carried out, placing the rocks and / or stones of greater diameter in the lower part and those of smaller diameter in the upper part, finally the earth and sand. The self-powered lifting hopper must be 100% loaded, if 60% is set it does not open.
La tolva se encuentra lista para ser izada e introducida en la torre de lixiviación hasta el fondo de la misma. Ai posarse en el fondo ésta procede a abrirse, con la inercia de la velocidad de bajada la quijada se destraba de ia uña guía; y como las caras laterales de la uña son a 45° al proceder nuevamente a izarla esta comienza a deslizarse por la curvatura que posee y como la quijada tiene menor peso que la caja de la tolva, los brazos de accionamiento de la quijada comienzan a abrir la tolva gradualmente. Depositando el material minero con mucha delicadeza para luego actuar los brazos de la caja, inclinándola gradualmente y quedando finalmente la tolva completamente suspendida y haciendo un ángulo de caída de 45°. La tolva suspendida hace una oscilación de 10s aproximadamente por efecto de la salida de la carga. The hopper is ready to be hoisted and introduced into the leaching tower to the bottom of it. Upon reaching the bottom it proceeds to open, with the inertia of the lowering speed the jaw is unlocked from the guide nail; and since the lateral faces of the nail are at 45 ° when proceeding to hoist it again, it begins to slide due to the curvature it has and since the jaw has less weight than the hopper box, the jaw drive arms begin to open the hopper gradually. Depositing the mining material very delicately to then act the arms of the box, gradually tilting it and finally leaving the hopper completely suspended and making a drop angle of 45 °. The suspended hopper makes an oscillation of approximately 10 s due to the effect of the load exit.
Llegando hasta los 55° de inclinación en un movimiento de vaivén. Para luego estabilizarse en 45° que es el ángulo de diseño para la descarga.  Reaching 55 ° inclination in a reciprocating motion. Then stabilize at 45 ° which is the design angle for the discharge.
Luego de la descarga y con la tolva suspendida, ésta se deposita nuevamente en el piso, a cerrarse y la quijada vuelve a engramparse sola automáticamente. Quedando la tolva de izaje auto-accionada cerrada y lista para salir de la torre de lixiviación e iniciar otra operación. After unloading and with the hopper suspended, it is deposited again on the floor, to be closed and the jaw is automatically stapled again. The self-powered lifting hopper is closed and ready to leave the leaching tower and start another operation.
El estado de la técnica con la presente tolva de izaje auto-accionada mejora la performance del llenado de las torres de lixiviación, cumpliendo con los estándares de SEGURIDAD MINERA en espacios confinados. The state of the art with the present self-powered lifting hopper improves the performance of filling the leaching towers, complying with the MINING SAFETY standards in confined spaces.
