Abstract

Current solutions: a) removing the nut first and then the washer, a slow process; and b) removing the nut together with the washer from a single hook, an unsafe process. At the end, it is finished by hand and the instability causes accidents among the operators. The proposed system uses the same basic idea of a washer with a hook but adds a second hook and a cylindrical bayonet socket that allows them to come all the way out together, without using the hands and without falling. Advantages: reduces total times, nuts and washers come all the way out together; does not need to be completed using the hands, reducing the possibility of accidents; and reduces the size of the die, as it is a single piece.

Description

SISTEMA PARA RETIRO DE TUERCAS Y GOLILLAS PARA REMOVAL SYSTEM OF NUTS AND NECKLETS FOR
REVESTIMIENTOS DE MOLINOS MILLING COATINGS
La patente de invención que se divulga es un sistema para retiro de tuercas y golillas para revestimientos de molinos, el objetivo del diseño divulgado es mejorar la velocidad y la seguridad en el trabajo de extracción de tuercas, golillas y pernos de revestimientos internos de molinos utilizados en distintas aplicaciones industriales o mineras. El cambio de los revestimientos de los molinos es la tarea crítica que define los tiempos totales para el mantenimiento y por lo mismo se buscan permanentemente herramientas, equipos, accesorios, procedimientos, etc. que ayuden a hacerla en el menor tiempo posible pero manteniendo una seguridad apropiada. The disclosed invention patent is a system for removing nuts and tails for mill liners, the objective of the disclosed design is to improve the speed and safety in the work of removing nuts, tails and bolts from internal mill liners used in different industrial or mining applications. The change of the linings of the mills is the critical task that defines the total times for maintenance and therefore tools, equipment, accessories, procedures, etc. are permanently sought. that help to do it in the shortest possible time but maintaining appropriate security.
Descripción de lo conocido en la materia Description of what is known in the art
Una de las ideas que ayuda a la rebaja de tiempos es una golilla con gancho lateral, patentada anteriormente, que permite retirar la golilla junto con la tuerca lo que reduce considerablemente el tiempo total para esa operación. One of the ideas that helps to reduce times is a neck with a lateral hook, previously patented, which allows the neck to be removed together with the nut, which considerably reduces the total time for that operation.
Esa golilla se ha estado usando en plantas mineras pero hay cierta resistencia en algunas de ellas porque, si se usa con una llave motorizada, hasta sacar ambas piezas completamente, se caen. Eso obliga a hacer una de dos cosas: la tuerca y la golilla se terminan de sacar a mano para que no caigan o se sacan completamente pero se bloquea el área bajo el espacio en que se trabaja sacando tuercas y pernos. That neck has been used in mining plants but there is some resistance in some of them because, if used with a motorized wrench, until both parts are completely removed, they fall off. That forces you to do one of two things: the nut and the neck are finished by hand so that they do not fall or are completely removed but the area under the space in which you work is removed by removing nuts and bolts.
Sacarlas a mano elimina la ventaja lograda con el tiempo y ha producido accidentes por movimientos inesperados del revestimiento cuando el técnico tiene la tuerca en la mano. Despejar el área bajo el lugar de trabajo elimina la posibilidad de trabajar en paralelo con el trabajo de los pernos. Las dos situaciones son pérdida para los tiempos de mantenimiento o para la seguridad. Removing them by hand eliminates the advantage gained over time and has caused accidents due to unexpected movements of the coating when the technician has the nut in hand. Clearing the area under the job site eliminates the possibility of working in parallel with bolt work. The two situations are loss for maintenance times or for safety.
El sistema para el retiro de las tuercas y las golillas que se divulga permite lograr el retiro de ambas piezas juntas, como es la idea original de la patente existente, pero asegura que la golilla y la tuerca no se caigan si se sacan completamente usando la llave motorizada. Eso mismo permite que las ventajas esperadas para la golilla original se cumplan y que se resumen en: The system for the removal of nuts and tails that is disclosed allows the removal of both parts together, as is the original idea of the existing patent, but ensures that the tails and nuts do not fall off if they are completely removed using the motorized wrench. That same allows the expected benefits for the original neck to be fulfilled and that is summarized in:
• Reducción del tiempo de mantenimiento • Reduced maintenance time
• Permite trabajar bajo el área de trabajo con los pernos • Allows working under the work area with the bolts
• Elimina la posibilidad de accidentes por tomar las piezas con la mano cuando las piezas quedan inestables por el retiro de las tuercas y las golillas. • Eliminates the possibility of accidents by taking the parts by hand when the parts are unstable due to the removal of the nuts and tails.

Figura 4: Vista del conjunto golilla ( 1), dado (2) y tuerca (3) . Descripción Detallada de la Invención Figure 4: View of the neck assembly (1), die (2) and nut (3). Detailed description of the invention
El sistema para retiro de tuercas y golillas para revestimientos de molinos comprende una golilla ( 1) de doble gancho (1.1) y un dado (2) con enganche (2. 1), doble, adaptado a la golilla ( 1) . El sistema divulgado permite lograr tiempos cortos y al mismo tiempo entrega la seguridad necesaria si se usan con una llave motorizada. The system for removal of nuts and tails for mill liners comprises a double hook taper (1) (1.1) and a double socket (2) with hook (2. 1), adapted to the taper (1). The disclosed system enables short times to be achieved and at the same time provides the necessary security when used with a motorized wrench.
La golilla ( 1) tiene dos ganchos ( 1. 1) pero además están desplazados de la superficie que queda en contacto con la tuerca (3); esta mejora hace que parte de la golilla ( 1) entre en el agujero cilindrico (2.2) del dado (2) lo que impide el desplazamiento entre las dos piezas a no ser que se desenganchen conscientemente completando el giro de ambas piezas entre sí. The neck (1) has two hooks (1. 1) but they are also displaced from the surface that is in contact with the nut (3); This improvement makes part of the neck (1) enter the cylindrical hole (2.2) of the die (2), which prevents the displacement between the two pieces unless they are consciously disengaged, completing the rotation of both pieces with each other.

REIVINDICACIONES
1.- Sistema para retiro de tuercas y golillas para revestimientos de molinos, concebido para reducir los tiempos y aumentar la seguridad en la tarea cuando esa operación se hace con llaves motorizadas. Elimina la necesidad de sacar las piezas a mano al final del recorrido y por lo tanto elimina el riesgo de accidentes cuando la pieza queda suelta e inestable. El sistema está caracterizado porque comprende una golilla (1) con doble oreja ( 1.1) y con un tramo cilindrico macho ( 1.2) que encaja en dos enganches (2. 1) y en un cilindro hembra (2.2) en un dado (2) hexagonal modificado que forma parte de esta invención. El sistema evita que la tuerca (3) (que no forma parte de la invención que se divulga, es una pieza estándar) y la golilla ( 1) se salgan del dado (2) si el técnico no lo hace voluntariamente mediante un giro de ambas piezas entre sí cuando se encuentra en posición segura. 1.- System for removing nuts and tails for mill liners, designed to reduce time and increase safety in the task when this operation is done with motorized wrenches. Eliminates the need to remove parts by hand at the end of the stroke and therefore eliminates the risk of accidents when the part is loose and unstable. The system is characterized in that it comprises a neck (1) with a double ear (1.1) and a male cylindrical section (1.2) that fits into two hooks (2.1) and a female cylinder (2.2) on a die (2) modified hexagonal part of this invention. The system prevents the nut (3) (which is not part of the disclosed invention, is a standard part) and the neck (1) from falling out of the die (2) if the technician does not do it voluntarily by turning both pieces to each other when in a safe position.
