Description

Dispositivo de fijación de cuchillas y patines en cuñas quitanieves.Blade and roller fixing device in snow plows.

Object of the invention

La presente invención, según se expresa en el enunciado de esta memoria descriptiva, se refiere a un dispositivo de fijación de cuchillas en cuñas quitanieves junto con un sistema auxiliar para la fijación de los patines a las cuñas quitanieves. Esto ha sido ideado y ejecutado con objeto de conseguir significativas ventajas con respecto al sistema convencional con análoga finalidad.The present invention, as expressed in the set forth in this specification, refers to a device of fixation of blades in snow plows together with a system auxiliary for fixing the skates to the snow plows. This has been devised and executed in order to achieve significant advantages over the conventional system with analogous purpose.

La misión de este nuevo sistema de fijación de cuchillas y patines es que la parte inferior del conjunto de la cuña quitanieves, que es la que va a sufrir un fuerte desgaste por el efecto abrasivo del roce con el terreno durante su vida útil, sea de fácil, rápido y cómodo recambio.The mission of this new fixing system of blades and skates is that the bottom of the set of the Snowplow wedge, which is going to suffer a strong wear by the abrasive effect of rubbing with the ground during its useful life, It is easy, fast and convenient replacement.

El dispositivo está ideado para que las cuchillas y los patines fijados a la cuña quitanieves queden debidamente sujetos en un soporte constituido por diferentes implementos y la propia cuña, de manera que su mantenimiento por recambio sea rápido, fácil y cómodo.The device is designed so that the blades and skates fixed to the snowplow wedge duly subject in a support constituted by different implements and the wedge itself, so that its maintenance by Spare quick, easy and convenient.

Esto se consigue gracias a un sistema de bulones con sus correspondientes pasadores de fijación. Realmente se trata de dos sistemas de sujeción a la cuña, uno para las cuchillas y otro para los patines, basado cada uno de ellos en tres piezas enclavables entre sí.This is achieved thanks to a bolt system with their corresponding fixing pins. It's really about of two wedge clamping systems, one for the blades and another for skates, each based on three pieces interlocking with each other.

Un primer sistema lo constituirían las cuchillas, los diferentes implementos, y la cuña, y el segundo sistema o auxiliar estaría formado por los patines, los correspondientes implementos y la cuña, de manera que las cuchillas queden sujetas en un sistema y los patines en el otro por medio de unos bulones con sus correspondientes pasadores.A first system would constitute the blades, the different implements, and the wedge, and the second system or auxiliary would consist of skates, corresponding implements and the wedge, so that the blades are subject in one system and the skates in the other through some bolts with their corresponding pins.

Tanto en un sistema como en el otro sobresaldrían cuchillas y patines por la parte inferior, quedando siempre las cuchillas ligeramente elevadas respecto de los patines. Esto es debido a que la función de los patines es mantener el conjunto de cuchillas y cuña ligeramente elevado sobre el terreno con objeto de que éste no se clave sobre el terreno impidiendo al camión su avance y por lo tanto el ejercicio de su función.Both in one system and in the other blades and skates would stand out from the bottom, leaving Always the blades slightly raised with respect to the skates. This is because the function of the skates is to maintain the set of blades and wedge slightly raised on the ground in order that it is not keyed on the ground preventing the truck its advance and therefore the exercise of its function.

Background of the invention

El sistema tradicional de fijación tanto de las cuchillas como de los patines a la cuña quitanieves ha sido mediante tuercas y tornillos.The traditional system of fixing both blades like from snow skates to wedge has been by nuts and bolts.

En el caso de las cuchillas, éstas contaban con una serie de orificios uniformemente distribuidos a lo largo de las mismas que se correspondían con otra serie análoga de orificios, del mismo tamaño y en el mismo número, distribuidos de la misma forma a lo largo de la parte inferior de la cuña. Los orificios de las cuchillas al quedar posicionados de forma enfrentada a los orificios de la cuña y ser atravesados por los tornillos y fijados por las tuercas hacían que el conjunto quedase fijado de forma solidaria.In the case of the blades, they had a series of holes evenly distributed along the same that corresponded to another similar series of holes, of the same size and in the same number, distributed of the same shape along the bottom of the wedge. The holes of the blades to be positioned facing the wedge holes and be pierced by screws and fixed by the nuts they made the whole set so solidarity.

Por su parte en el sistema tradicional, los patines también se fijaban a la cuña mediante tuercas y tornillos con la única salvedad de que mientras los orificios para los patines no eran pasantes si lo eran para el caso de la cuña.For their part in the traditional system, the skates were also fixed to the wedge by nuts and bolts with the only caveat that while the holes for skates were not interns if they were for the wedge case.

Estos sistemas de fijación mediante tuercas y tornillos presentaban el inconveniente de la dificultad, incomodidad y lentitud en el recambio de las cuchillas y patines ya que eran necesarias herramientas específicas para el recambio, lo que daba lugar a que no pudiera realizarse en carretera sino que era necesario llevar el camión quitanieves al taller.These fixing systems using nuts and screws presented the inconvenience of difficulty, discomfort and slowness in the replacement of the blades and skates already that specific tools were needed for the replacement, what which meant that it could not be done on the road but it was It is necessary to take the snow plow to the workshop.

Esto implicaba la consiguiente pérdida de tiempo y de productividad, además de los costes económicos asociados a la labor del taller y unidos a la posibilidad añadida de lesiones lumbares por parte de operarios del taller por la realización de sus labores en posturas inadecuadas durante bastante tiempo.This implied the consequent loss of time. and productivity, in addition to the economic costs associated with the workshop work and together with the added possibility of injuries lumbar by operators of the workshop for the realization of their work in inappropriate postures for quite some time.

Description of the invention

El sistema de fijación de la invención, o mejor dicho los sistemas de fijación de la invención si hacemos distinción entre el sistema de fijación de las cuchillas, por un lado, y el sistema auxiliar de fijación de los patines, por otro, presentan una nueva estructura gracias a la cual la sujeción se realiza con gran eficacia y de forma sencilla como en el método tradicional, siendo en cambio su recambio mucho más sencillo, cómodo y rápido. Esta última parte refleja el carácter novedoso, la actividad inventiva y la aplicabilidad del nuevo sistema.The fixing system of the invention, or better said fixing systems of the invention if we do distinction between the blade fixing system, by a side, and the auxiliary system for fixing the skates, on the other, they present a new structure thanks to which the support is performs very efficiently and easily as in the method traditional, however its replacement is much simpler, comfortable and fast. This last part reflects the novel character, the Inventive activity and the applicability of the new system.

Comenzando a describir el nuevo sistema de fijación de las cuchillas se partiría de unos elementos novedosos respecto del sistema convencional denominados implementos de una longitud del orden del de las cuchillas y con dos partes bien diferenciadas.Starting to describe the new system of blade fixing would be based on some innovative elements with respect to the conventional system called implements of a length of the order of the blades and with two parts well differentiated.

Estos implementos en uno de sus dos lados longitudinales dispondrían de una serie de orificios pasantes gracias a los cuales los implementos se fijarían a la cuña por el método convencional de tuercas y tornillos. En la cara externa de este lado longitudinal se dispondrían una serie de nervios de refuerzo uniformemente distribuidos para dotar de la rigidez necesaria al implemento y poderse así fijar a la cuña con la presión necesaria.These implements on one of its two sides longitudinal would have a series of through holes thanks to which the implements would be fixed to the wedge by the conventional method of nuts and bolts. On the outer face of this longitudinal side would be arranged a series of nerves of uniformly distributed reinforcement to provide stiffness necessary to implement and thus be able to fix the wedge with the necessary pressure.

El otro de los lados longitudinales del implemento contaría en su parte interna de la concavidad necesaria para el alojamiento de las bases de las cuchillas en el espacio comprendido entre los implementos y la cuña, sirviendo la base de la concavidad de tope para la penetración de la base de la cuchilla en el espacio del que se ha hablado. Este lado longitudinal también contaría con una serie de orificios longitudinales pasantes uniformemente distribuidos y paralelos al borde del implemento. Sin embargo, el número de orificios de este lado sería menor que el del otro lado longitudinal y además serían de un diámetro mayor.The other of the longitudinal sides of the implement would count inside the necessary concavity for housing the bases of the blades in space between the implements and the wedge, serving the basis of the concavity stop for penetration of the blade base in the space that has been talked about. This longitudinal side too would have a series of through longitudinal holes evenly distributed and parallel to the edge of the implement. Without However, the number of holes on this side would be less than that of the other longitudinal side and also would be of a larger diameter.

De idéntico número de orificios y dispuestos de la misma forma contarían las cuchillas en su base y la cuña en su parte más baja. Su misión es que enfrentadas las tres series de orificios pasantes, estos fueran atravesados por los bulones, dejando bloqueada su salida con los pasadores, quedando así fijadas las cuchillas a la cuña. Evidentemente el número de orificios necesarios para la fijación sería menor siendo en cambio estos de mayor diámetro debido a la mayor robustez de los bulones frente a los tor-
nillos.In the same number of holes and arranged in the same way would count the blades at its base and the wedge at its lowest part. Its mission is that faced with the three series of through holes, these were crossed by bolts, leaving their exit blocked with the pins, thus fixing the blades to the wedge. Obviously the number of holes required for fixing would be smaller, however, these are larger in diameter due to the greater robustness of the bolts against the torques.
nillos

A continuación se pasa a describir el sistema de fijación de los patines, los cuales serían un elemento auxiliar para la función a desarrollar por el conjunto cuchillas - cuña como ya se ha descrito. De manera análoga, a lo descrito anteriormente para el caso de las cuchillas, se dispondría de unos implementos aunque con un diseño distinto al del sistema anterior.Next, the system of fixing the skates, which would be an auxiliary element for the function to be developed by the blades set - wedge like It has already been described. Similarly, as described above in the case of the blades, some implements would be available although with a different design from the previous system.

Por un lado, la cara interna de los implementos del patín seria la cara que va pegada mediante soldadura a la cuña por su parte inferior y posterior a la zona cuña-cuchillas.On the one hand, the internal face of the implements of the skate would be the face that is glued by welding to the wedge by its inferior part and later to the zone wedge-blades.

Por otro lado, el implemento en su lado externo se caracterizaría por una guía encajonada que serviría para el alojamiento de la base de los patines e impediría su desplazamiento con respecto a la cuña en sentido vertical, siendo el desplazamiento horizontal impedido por un bulón con su correspondiente pasador que atravesaría el extremo de la base del patín (aquella parte del patín que quedaría en voladizo al ser soldada a la cuña).On the other hand, the implement on its external side it would be characterized by a boxed guide that would serve for the accommodation of the base of the skates and would prevent its displacement with respect to the wedge vertically, being the horizontal displacement prevented by a bolt with its corresponding pin that would cross the end of the base of the skate (that part of the skate that would be cantilevered to be welded to the wedge).

Por último, el diseño final de los patines también se vena afectado por el nuevo sistema de fijación, teniendo una configuración distinta al del sistema tradicional al estar constituidos por un patín convencional en forma de prisma cuadrangular soldado a una placa con uno orificio en uno de sus laterales para el paso del bulón.Finally, the final design of the skates it is also affected by the new fixation system, having a different configuration from the traditional system to be constituted by a conventional skate in the form of a prism quadrangular soldier to a plate with one hole in one of its lateral for the passage of the bolt.

Como conclusión, gracias a este nuevo sistema de fijación el recambio de las cuchillas seria mas fácil y rápido, no requiriendo de herramientas ni de asistencia a taller, pudiéndose realizar, en caso necesario, por el propio chofer del camión.In conclusion, thanks to this new system of fixing the replacement of the blades would be easier and faster, no requiring tools or workshop assistance, being able to carry out, if necessary, by the truck driver himself.

Preferred Embodiment of the Invention

A la vista de las citadas figuras, puede observarse como en el caso del sistema de fijación de cuchillas éste se constituye mediante tres piezas acoplables entre sí, (cuña, cuchilla e implemento) por medio de unos bulones con sus correspondientes pasadores.In view of the cited figures, you can observe as in the case of the blade fixing system this is constituted by three pieces that can be coupled together, (wedge, blade and implement) by means of some bolts with their corresponding pins.

El implemento, como se aprecia en las figuras 1 y 2, es en grandes rasgos una pieza alargada que puede ser, o bien de forma trapezoidal en uno de sus lados, para el caso de los implementos que se encuentran posicionados en uno de los extremos laterales, como el mostrado en la figura 1, (realmente los implementos laterales son dos siendo el segundo simétrico al mostrado en dicha figura), o bien rectangular, como el mostrado en la figura 2, para el caso de los implementos que se localicen en la zona central de la cuña. En dicho implemento se pueden distinguir claramente dos partes de carácter longitudinal, (1) y (2), y con funciones diferentes, así como con características distintas en función de si se está hablando de su cara interna o bien de su cara externa.The implement, as seen in figures 1 and 2, it is in broad strokes an elongated piece that can be either trapezoidal on one of its sides, in the case of implements that are positioned at one end lateral, as shown in figure 1, (really the side implements are two being the second symmetric to shown in said figure), or rectangular, as shown in Figure 2, in the case of the implements that are located in the central wedge area. In this implement can be distinguished clearly two parts of a longitudinal nature, (1) and (2), and with different functions, as well as with different characteristics in function of whether you are talking about your inner face or your face external

El lado longitudinal pegado a las cuchillas (2) cuenta con una parte cóncava (3) con resalte (4) para el alojamiento y asiento de las cuchillas (19), y una parte externa convexa lisa (5), excepto por las perforaciones (6) o agujeros pasantes que se distribuyen a todo lo largo y de forma uniforme de este lado (5) y cuyo diámetro es ligeramente superior al de los bulones para su fácil y rápido montaje-desmontaje.The longitudinal side glued to the blades (2) It has a concave part (3) with protrusion (4) for the blade housing and seat (19), and an external part smooth convex (5), except for perforations (6) or holes interns that are distributed throughout and uniformly this side (5) and whose diameter is slightly larger than the bolts for easy and fast assembly-disassembly.

El lado longitudinal contra la cuña cuenta también con una cara externa (7) y otra interna (8) bien diferenciadas. La cara interna (8) es aquella que apoya contra la cuña y que cuenta con una serie de agujeros pasantes (9) uniformemente distribuidos a todo lo largo del mismo con diámetro ligeramente superior al de los tornillos que lo atraviesan para fijar el implemento a la cuña. La cara externa de este lado longitudinal contaría con una serie de nervios, (10) y (11), a modo de refuerzo uniformemente distribuidos y de altura comprendida desde el extremo del lado longitudinal descrito (7) al comienzo de la parte convexa (12) del implemento, tal y como puede apreciarse en la figura. Estos nervios sirven para dotar al implemento de la rigidez suficiente de forma que al estar trabajando las cuchillas, y apoyarse contra el implemento y la cuña, no deformen el implemento.The longitudinal side against the wedge counts also with an external face (7) and an internal one (8) well differentiated. The inner face (8) is the one that leans against the wedge and it has a series of through holes (9) evenly distributed all along it with diameter slightly higher than the screws that cross it to fix the implement to the wedge. The outer face of this side longitudinal would have a series of nerves, (10) and (11), by way of uniformly distributed reinforcement and height included from the end of the longitudinal side described (7) at the beginning of the convex part (12) of the implement, as can be seen in the figure. These nerves serve to provide the implement with the sufficient rigidity so that when the blades are working, and lean against the implement and the wedge, do not deform the implement.

La forma de los nervios (11) es trapezoidal, excepto para el nervio en el implemento trapezoidal junto al lado oblicuo el cual es de forma triangular.The shape of the nerves (11) is trapezoidal, except for the nerve in the trapezoidal implement next to the side oblique which is triangular in shape.

En cuanto al sistema de fijación de los patines auxiliares (20), los cuales se muestran detalladamente en las figuras 3 y 4, estos se fijan a la cuña del quitanieves a través de implementos (21), tal y como se puede observar en la figura 5.As for the system for fixing the skates auxiliaries (20), which are shown in detail in the Figures 3 and 4, these are fixed to the snowplow wedge through implements (21), as can be seen in figure 5.

Los implementos (21) son el resultado de una placa metálica lisa por todo su contorno en la que en uno de sus lados se le ha practicado un cajeado (13) a modo de guía, y en uno de sus extremos de la cara mayor (14) y de forma centrada con respecto al eje del cajeado-guía se le ha practicado un orificio pasante (15). La misión del cajeado (13) es la fijación vertical del patín en la cuña por su base mientras que la misión del orificio (15) es permitir el paso del bulón que fijará horizontalmente el patín al atravesar su base (16) y el implemento.The implements (21) are the result of a smooth metal plate throughout its contour in which in one of its sides have been recessed (13) as a guide, and in one of its ends of the major face (14) and centered with with respect to the axis of the guideline, it has been practiced a through hole (15). The mission of the cajeado (13) is the fixation vertical skate on the wedge by its base while the mission of the hole (15) is to allow the passage of the bolt that will fix horizontally the skate when crossing its base (16) and the implement.

Por su parte, el patín (20) consta de una placa metálica (16) soldada a un prisma cuadrangular (17) por una de sus caras laterales, de tal forma que uno de sus lados queda al ras de uno de los lados de la placa (16), siendo en el lado opuesto de ésta donde se encuentra el orificio (18) para el paso del bulón.For its part, the skate (20) consists of a plate metal (16) welded to a quadrangular prism (17) by one of its side faces, so that one of its sides is flush with one of the sides of the plate (16), being on the opposite side of this where the hole (18) for the bolt passage is located.
