Description

G APA DE TIRO PARA CORREAS TRANSPORTADORAS  G SHOOTING APA FOR CONVEYOR BELTS
Descripción de lo conocido en la materia La presente solicitud está dirigida a una grapa de tiro para tirar correas transportadoras mediante un cable. Teniendo como principal ámbito de aplicación la industria minera y otras industrias que involucren el transporte de materiales mediante correas transportadoras. Description of the known in the art The present application is directed to a pull clamp for pulling conveyor belts by means of a cable. Having as main scope of application the mining industry and other industries that involve the transport of materials through conveyor belts.
Para efectuar los cambios de correas transportadoras, actualmente se utilizan los siguientes métodos: grapas de empalme mecánico, unión tipo cordón de zapatos, placas de tiro, ahorcamiento de correa, ranuras con disposición triangular y uso de prensas. Las grapas de empalme mecánico son la tecnología más cercana a la presente invención. A continuación se realizará una revisión de cada una de estas tecnologías: To make the changes of conveyor belts, the following methods are currently used: mechanical splice staples, shoe cord type connection, shooting plates, belt hanging, triangular slots and use of presses. Mechanical splice staples are the technology closest to the present invention. A review of each of these technologies will be carried out below:
A) Grapas de empalme mecánico La tecnología de grapa de empalme mecánico fue desarrollada hace varias décadas, siendo usada en diversas industrias que requieran el transporte de materiales a granel. Sin embargo estas placas de empalme mecánico, tal y como su nombre lo dice, fueron diseñadas para empalmar los extremos de una misma correa transportadora con el fin de generar su cierre y su posterior montaje y operación en forma continua. Esta tecnología representa el estado del arte más cercano a la grapa de tiro para tirar correas transportadoras. A) Mechanical splice staples Mechanical splice staple technology was developed several decades ago, being used in various industries that require the transport of bulk materials. However, these mechanical splice plates, as the name says, were designed to join the ends of the same conveyor belt in order to generate its closure and its subsequent assembly and operation in a continuous manner. This technology represents the state of the art closest to the pull clamp for pulling conveyor belts.
La desventaja de esta tecnología es que no se conoce su capacidad de tiro, dado que fue diseñada para el empalme de correas transportadoras, por lo que cada grapa está diseñada para ir en contacto exclusivo con la correa y no para unir y transmitir la fuerza de tiro entre la correa y el cable de tiro como es utilizada en la actualidad, produciéndose el desgarro de la correa en algunas uniones de las grapas. B) Unión tipo cordón de zapatos Este método consiste en realizar sacados dispuestos en forma simétrica respecto al eje central de la correa y posteriormente se pasa un cable de tiro por estos sacados en forma cruzada hasta juntarse ambos extremos mediante una grapa de cable, formándose un lazo cerrado. The disadvantage of this technology is that its shooting capacity is not known, since it was designed for the splicing of conveyor belts, so each staple is designed to be in exclusive contact with the belt and not to join and transmit the force of shot between the belt and the cable of shot as it is used at present, being produced the tearing of the belt in some unions of the staples. B) Lace shoe type union This method consists of making outlets arranged symmetrically with respect to the central axis of the belt and then passing a cable through these crossed out until both ends are joined by a cable clamp, forming a closed loop.
Las desventajas de esta tecnología es que no se conoce su capacidad de tiro ni hay una forma analítica de calcular la fuerza transmitida en la unión, por lo que usualmente es utilizada para mover correas de pequeña envergadura. Además presenta desgarros en la zona de los sacados. The disadvantages of this technology is that its shooting capacity is not known nor is there an analytical way to calculate the force transmitted in the joint, so it is usually used to move small belts. It also has tears in the area of the removed.
C) Placas de Tiro C) Shooting Plates
Esta tecnología consiste en dos placas dispuestas en la cubierta superior e inferior de la correa, unidas mediante pernos que atraviesan la correa; cada una de estas placas contiene un agujero pasante con un refuerzo. Luego el cable de tiro se pasa por dicho agujero y se cierra mediante una grapa de cable. This technology consists of two plates arranged in the upper and lower cover of the belt, joined by bolts that go through the belt; Each of these plates contains a through hole with a reinforcement. Then the draft cable is passed through said hole and closed by a cable clamp.
Pese a que se conoce su capacidad de tiro, esta tecnología presenta la desventaja de no tener flexibilidad longitudinal, por lo que las maniobras de tiro se ven obstaculizadas al pasar por las poleas y al llegar al carrete enrollador. Debido a esta poca flexibilidad longitudinal hay una gran tendencia al desgarro de la correa en la zona de la placa de tiro. Además la placa suele quedar atrapada en las estructuras de la correa transportadora y en los chutes de carga de material. Although its shooting capacity is known, this technology has the disadvantage of not having longitudinal flexibility, so that shooting maneuvers are hampered when going through the pulleys and upon reaching the reel reel. Due to this little longitudinal flexibility there is a great tendency to tear the belt in the area of the shooting plate. In addition, the plate is often trapped in the structures of the conveyor belt and in the material loading chutes.
D) Ahorcamiento de correa Este método de tiro consiste en formar una garganta en la correa mediante el ahorcamiento de esta con un cable de acero que se enrolla y aprieta hasta cerrar la unión con grapas de cable. D) Belt hanging This method of pulling consists of forming a throat in the belt by hanging it with a steel cable that is wound and tightened until the connection with cable clamps is closed.
La desventaja de este método es que resulta ser bastante rústico, por lo que no se conoce su capacidad de tiro y la efectividad de este depende del tipo de amarra realizada y de lo apretada que esté. Además la punta queda con una configuración no deseada y por tanto, difícil de ordenar en el carrete enrollador. Por otro lado, este método presenta dificultad de maniobra, dado que la correa se enreda en estructuras y en el chute de carga de material. The disadvantage of this method is that it turns out to be quite rustic, so its shooting capacity is not known and the effectiveness of this depends on the type of tie made and how tight it is. In addition the tip remains with an unwanted configuration and therefore, difficult to order on the reel reel. On the other hand, this method presents difficulty of maneuver, given that the belt is entangled in structures and in the load chute of material.
E) Uso de ranuras con disposición triangular Este método consiste en realizar tres sacados con disposición triangular en la correa. Luego se pasa un cable de acero por las ranuras hasta cerrar la unión mediante el uso de grapas de cable. E) Use of grooves with triangular arrangement This method consists of making three exits with a triangular arrangement on the belt. Then a steel wire is passed through the slots until the joint is closed by the use of cable clips.
La desventaja de este método es que no se conoce su capacidad de tiro y hay mucha tendencia al desgarro de la correa en el área de las ranuras. F) Uso de prensas The disadvantage of this method is that its pulling capacity is not known and there is a great tendency to tear the belt in the area of the grooves. F) Use of presses
Este método consiste en una prensa que aprieta la correa mediante pernos en sus extremos. Además la prensa contiene dos placas con agujeros pasantes en sus extremos, por las cuales pasa un cable de tiro con dos gazas en sus extremos. This method consists of a press that tightens the belt by bolts at its ends. In addition, the press contains two plates with through holes at their ends, through which passes a pulling cable with two loops at its ends.
Pese a que esta tecnología permite conocer la capacidad de tiro requerida, la estructura metálica de la prensa es muy rígida y hace perder flexibilidad longitudinal a la correa. Además de ser muy ancha, por lo que la correa se enreda en las estructuras adyacentes y no se puede incorporar al carrete del enrollador en forma idónea. Although this technology allows to know the required shooting capacity, the metallic structure of the press is very rigid and loses longitudinal flexibility to the belt. In addition to being very wide, so that the strap is entangled in the adjacent structures and can not be incorporated into the winder reel in an ideal way.
La presente invención resuelve los problemas descritos anteriormente con una grapa de tiro que permite un acople simple, seguro y eficiente entre el cable de tiro y la correa transportadora; existiendo un mejor agarre entre la grapa de tiro y el cable de tiro, evitando el deslizamiento del cable. The present invention solves the problems described above with a pull clamp that allows a simple, safe and efficient coupling between the pull cable and the conveyor belt; There is a better grip between the pull clamp and the pull cable, avoiding slippage of the cable.
Otra de las ventajas principales de la presente invención es que su capacidad de tiro es conocida. Another of the main advantages of the present invention is that its pulling capacity is known.
Además, esta grapa de tiro permite conservar la flexibilidad longitudinal de la correa, evitando el desgarre de esta en la zona de unión con las grapas y evitando también el atrapamiento de la correa en polines, chutes de carga, poleas, raspadores, etc. In addition, this staple of draft allows to conserve the longitudinal flexibility of the belt, avoiding the tearing of this in the area of union with the staples and also preventing the entrapment of the belt in skids, cargo chutes, pulleys, scrapers, etc.
Por último, esta grapa de tiro ofrece una gran versatilidad en cuanto al uso de distintos diámetros de cables de tiro. Breve descripción de los dibujos Finally, this shooting clamp offers great versatility in terms of the use of different diameters of draft cables. BRIEF DESCRIPTION OF THE DRAWINGS

Descripción detallada de la invención Detailed description of the invention
95 Consiste en una grapa de tiro para tirar correas transportadoras mediante un cable. Se conforma de 3 placas, una placa superior (1), una placa central (2) y otra placa inferior (3). La placa central (2) e inferior (3) se anclan a la correa transportadora (16); y la placa superior (1) y central (2) sostienen mediante un perfil circular (4) y (5) al cable de tiro (14) utilizado para tirar la correa transportadora (16). Para que el conjunto opere en forma correcta se 100 utilizan dos conectores pasantes (8) que aprietan tanto al cable de tiro (14) como a la correa transportadora (16). 95 Consists of a pull clamp to pull conveyor belts using a cable. It consists of 3 plates, an upper plate (1), a central plate (2) and another lower plate (3). The central plate (2) and lower plate (3) are anchored to the conveyor belt (16); and the upper plate (1) and central plate (2) support by means of a circular profile (4) and (5) the pulling cable (14) used to pull the conveyor belt (16). In order for the assembly to operate correctly, two through connectors (8) are used which tighten both the draft cable (14) and the conveyor belt (16).
La placa superior (1) presenta hendiduras cónicas (10) con resaltes (9) para que la cabeza avellanada de los conectores pasantes (8) encaje y no deslice, por lo que para apretar el conjunto de placas solo se requiere aplicar torque en la tuerca (12) que va en la hendidura 105 cónica de la placa inferior (3). Las golillas (13) tienen un agujero pasante interior con ajuste de holgura localizado para impedir que la cabeza de los conectores pasantes (8) se separe de la hendidura cónica (10) de la placa superior (1). The upper plate (1) has conical grooves (10) with projections (9) so that the countersunk head of the through connectors (8) fits and does not slide, so to tighten the set of plates only requires applying torque in the nut (12) that goes in the conical slot 105 of the lower plate (3). The lugs (13) have an internal through hole with localized clearance adjustment to prevent the head of the through connectors (8) from separating from the conical groove (10) of the upper plate (1).
El perfil circular de la parte media de la placa superior (4) y el perfil circular de la parte media de la placa central (5) están diseñados para contener al cable de tiro (14), para lo 110 cual tienen en su superficie de contacto, un estampado rugoso (6) y (7), que corresponde a la matriz de un cable; de tal forma de aumentar el área de contacto y que no exista deslizamiento entre el cable y las placas superior (1) y central (2). La placa central (2) y la placa inferior (3) presentan dientes de agarre (11) en sus bordes laterales hacia el lado de la correa transportadora (16) para enterrarse en esta, evitando el 115 deslizamiento y permitiendo un mejor agarre. The circular profile of the middle part of the upper plate (4) and the circular profile of the middle part of the central plate (5) are designed to contain the draft cable (14), for which they have on their surface contact, a rough pattern (6) and (7), which corresponds to the matrix of a cable; in such a way to increase the contact area and that there is no slip between the cable and the upper (1) and central (2) plates. The central plate (2) and the lower plate (3) have gripping teeth (11) on their side edges towards the side of the conveyor belt (16) to be buried in it, avoiding slippage and allowing a better grip.
Las dimensiones de cada grapa dependerán de las especificaciones técnicas de la correa y de la tensión de tiro requerida para el cambio de esta. The dimensions of each staple will depend on the technical specifications of the belt and the tension of draft required for the change of this.
La utilización de tres placas permite que la grapa de tiro se pueda utilizar para un rango de distintos diámetros de cables de tiro (14). The use of three plates allows the draw clamp to be used for a range of different diameters of firing cables (14).

Ejemplos de aplicación Application examples
Cuando las correas transportadoras cumplen con su vida útil, estas deben ser removidas y cambiadas por una correa nueva. Para esto se retira la correa desgastada mediante el 125 acople de esta a un cable de tiro que a su vez es traccionado por un enrollador. La presente patente de invención permite acoplar la correa transportadora al cable de tiro. When the conveyor belts meet their useful life, they must be removed and replaced by a new belt. To this end, the worn belt is removed by means of the coupling of this one to a pulling cable that in turn is pulled by a reel. The present invention patent allows coupling the conveyor belt to the draft cable.
La utilización de las grapas de tiro es en forma conjunta como se muestra en la figura 4, es decir, se deben utilizar varias grapas para acoplar la correa transportadora al cable de tiro. De este modo se busca repartir la fuerza para tirar la correa en todo el conjunto. The use of the pull clamps is jointly as shown in Figure 4, that is, several staples must be used to attach the conveyor belt to the pull line. In this way it is sought to distribute the force to pull the strap throughout the whole.
130 La disposición de las grapas es en forma de gota como se muestra en la figura 4, con el fin de que la fuerza de tiro se distribuya en todas las grapas de tiro. De este modo, el cable de tiro (14) pasará por todas las grapas de tiro que apretarán a éste en forma uniformemente distribuida hasta unirse con el otro extremo de cable mediante el uso de grapas de cable (15), ya comercializadas en el mercado. 130 The arrangement of the staples is in the form of a drop as shown in figure 4, so that the force of draft is distributed in all the staples. In this way, the draft cable (14) will pass through all the staples that will tighten it in a uniformly distributed manner until it is joined with the other end of the cable through the use of cable clamps (15), already commercialized in the market. .
135 La cantidad de grapas a utilizar dependerá de la tensión de tiro requerida para realizar el cambio de correa, del ancho de correa y del tipo de cable de tiro que se disponga. 135 The number of staples to be used will depend on the pulling tension required to make the belt change, the belt width and the type of pull cable that is available.
