Máquina explanadora de carreteras.Road grader machine.
La presente invención se refiere a mejoras en máquinas explanadoras de carreteras, a las que de forma alternativa se hace referencia como máquinas de fresado en frío.The present invention relates to improvements in road graders, to which alternatively It is referred to as cold milling machines.
Las máquinas explanadoras de carreteras se usan para retirar la zona superficial de carreteras como preparación para extender una superficie nueva. Funcionan haciendo entrar en contacto un tambor giratorio equipado con una serie de elementos cortadores con la superficie, la cual se fragmenta y se retira. Generalmente, la configuración de la serie de elementos cortadores es en espiral de tal manera que, cuando el tambor gira, el material superficial fragmentado o "virutas", bien es llevado hacia un extremo del tambor para retirarlo o bien se concentra en una zona central, de cara a su expulsión hacia un transportador de descarga.Road graders are used to remove the surface area of roads in preparation for extend a new surface. They work by making contact a rotating drum equipped with a series of cutter elements with the surface, which is fragmented and removed. Usually, The configuration of the series of cutter elements is spiral such that, when the drum rotates, the surface material fragmented or "chips", it is well taken to one end of the drum to remove it or it is concentrated in a central area of face expulsion to a discharge conveyor.
El tambor de explanación está situado a bordo del chasis de la máquina y está montado de forma descentrada de manera que un extremo del tambor se extiende cerca del lateral de la máquina; el tambor se eleva y se baja mediante la modificación de la altura de las ruedas traseras de carretera con respecto al chasis. La rueda trasera de carretera en el lado del "tambor" de la máquina está montada en un pivote de tal manera que se puede posicionar delante del tambor cuando la máquina se usa para explanar una zona contigua a un bordillo u otra línea limítrofe y que llega hasta el mismo, o junto al tambor y fuera del mismo cuando la máquina se usa para explanar una zona separada del bordillo. Las máquinas explanadoras de carreteras también pueden estar dotadas de una rueda cortadora lateral montada en el lado del tambor y fuera del chasis más allá del tambor de explanación, con el fin de abrir un surco o zanja en el lateral de la carretera o calzada, o para eliminar bordillos. Típicamente, dichas ruedas tienen una anchura bien de 80 mm o bien de 300 mm y cortan a una profundidad de hasta 400 mm. La superficie de la rueda está provista de una serie de elementos cortadores con punta de carburo los cuales están en ángulo hacia delante en la dirección del desplazamiento de la parte inferior de la acción de corte de la rueda en la carrera ascendente. De este modo, cuando la máquina avanza, la rueda cortadora gira en la dirección inversa de manera que la parte inferior de la rueda se mueve en la dirección de avance y los elementos cortadores cortan y retiran el material a modo de cuchara. No obstante, especialmente con ruedas cortadoras de 300 mm de ancho, la rueda cortadora crea una fuerza de arrastre sustancial en el lado del tambor de la máquina, lo cual tiende a provocar que la máquina adopte una postura de tipo "cangrejo" a medida que avanza. Esto da como resultado no solamente un desgaste acelerado de las puntas de los cortadores sino un desgaste en el borde y el lado internos de la propia rueda cortadora, ya que entra en contacto con el lateral de la zanja en la carrera descendente; hasta cierto punto, esto también produce el resultado desagradable de que la integridad del lateral de la zanja se ve comprometida.The esplanade drum is located on board the machine chassis and is decently mounted so that one end of the drum extends near the side of the machine; the drum is raised and lowered by modifying the height of the rear road wheels with respect to the chassis. The rear road wheel on the "drum" side of the machine is mounted on a pivot so that it can be position in front of the drum when the machine is used to explain an area adjacent to a curb or other borderline and that arrives to it, or next to the drum and out of it when the machine is used to explain a separate area of the curb. The road graders can also be equipped with a side cutter wheel mounted on the side of the drum and outside of the chassis beyond the esplanade drum, in order to open a groove or ditch on the side of the road or driveway, or for Remove curbs. Typically, said wheels have a width either 80 mm or 300 mm and cut to a depth of up to 400 mm The surface of the wheel is provided with a series of carbide tip cutting elements which are angled forward in the direction of movement of the part bottom of the wheel cutting action in the upward stroke. Thus, when the machine advances, the cutting wheel rotates in the reverse direction so that the bottom of the wheel is moves in the forward direction and the cutters cut and they remove the material like a spoon. However, especially with 300 mm wide cutting wheels, the cutting wheel creates a substantial drag force on the drum side of the machine, which tends to cause the machine to take a stand "crab" type as it progresses. This is the result not only accelerated wear of the tips of the cutters but wear on the inner edge and side of the wheel itself cutter, as it comes into contact with the side of the ditch in the descending race; to some extent, this also produces the unpleasant result that the integrity of the side of the ditch It is compromised.
El documento WO-A-95/11346 describe un aparato de fresado de carreteras que se sostiene sobre tres ruedas en los vértices de un triángulo el cual es asimétrico en relación con la dirección de funcionamiento del aparato, estando dispuesto el tambor cortador fuera del triángulo. El documento DE-A-3620120 describe una máquina explanadora de carreteras que tiene una rueda cortadora montada en un lado del tambor de explanación. El documento DE-A-19504495 describe una máquina explanadora que tiene una barra trituradora, para granular piezas grandes desprendidas de pavimentos de asfalto, montada en una zona contigua al tambor de explanación. El documento US4221434 describe una máquina explanadora de tambor que tiene placas rompedoras para proporcionar una fuerza de izalladura de compensación en la zona superior de la calzada a una distancia predeterminada con respecto al tambor de explanación, para reducir a un tamaño uniforme los recortes extraídos de la calzada.The document WO-A-95/11346 describes an apparatus of road milling that is held on three wheels in the vertices of a triangle which is asymmetric in relation to the direction of operation of the apparatus, the drum being arranged Cutter out of the triangle. The document DE-A-3620120 describes a machine road grader that has a cutter wheel mounted on one side of the esplanade drum. The document DE-A-19504495 describes a machine explanadora that has a crusher bar, to granulate pieces large detached asphalt pavements, mounted in an area next to the esplanade drum. US4221434 describes a drum grader machine that has breaker plates for provide a clearing force in the area over the road at a predetermined distance from to the esplanade drum, to reduce to a uniform size the clippings taken from the road.
En un aspecto, la presente invención proporciona una máquina explanadora de carreteras que incluye un tambor de explanación, presentando la máquina un chasis con ruedas delanteras de carretera para proporcionar una capacidad de dirección y ruedas principales de carretera para sostener el tambor de explanación, en las que la rueda principal de carretera en el lado del tambor de la máquina esta posicionada detrás del tambor, incluyendo la montura para la rueda trasera de carretera medios para modificar selectivamente el ángulo de la misma a cada lado de un plano vertical paralelo al eje longitudinal de la máquina, caracterizada porque una rueda cortadora está montada coaxialmente con respecto al tambor de explanación y en un lado del mismo y un miembro de contención de bordillos está montado delante de la rueda cortadora para moverse entre posiciones de elevación y de descenso, con lo cual mientras se está usando en la posición de descenso el miembro actúa de manera que sujeta los bordillos contra la acción de levantamiento de la rueda cortadora.In one aspect, the present invention provides a road grader machine that includes a drum esplanade, presenting the machine a chassis with front wheels road to provide steering and wheel capacity main road to hold the esplanade drum, in which the main road wheel on the drum side of the machine is positioned behind the drum, including the mount for the rear road wheel means to modify selectively the angle of it on each side of a plane vertical parallel to the longitudinal axis of the machine, characterized because a cutting wheel is coaxially mounted with respect to the esplanade drum and on one side of it and a member of curb containment is mounted in front of the cutting wheel to move between lifting and lowering positions, with which while the member is being used in the down position acts in a way that holds the curbs against the action of Lifting the cutting wheel.
Cuando la máquina se está usando, la capacidad de modificar selectivamente el ángulo de la rueda de carretera a cada lado de un plano vertical paralelo al eje longitudinal de la máquina permite que el conductor "dirija" la parte trasera de la máquina de manera que proporciona una resistencia o acción de oposición adicional con respecto a la tendencia al desplazamiento de tipo cangrejo, en comparación con la resistencia ya proporcionada por medio del posicionamiento de la rueda principal de carretera en el lado del tambor de la máquina detrás del tambor.When the machine is being used, the ability to selectively modify the angle of the road wheel at each side of a vertical plane parallel to the longitudinal axis of the machine allows the driver to "direct" the back of the machine so that it provides a resistance or action of additional opposition regarding the displacement trend of crab type, compared to the resistance already provided by positioning the main road wheel in the drum side of the machine behind the drum.
Cuando la máquina según la invención se usa para abrir un surco o zanja con la rueda cortadora lateral, el tambor se usa sin los elementos cortadores de explanación y se selecciona la altura mínima del chasis, de tal manera que la superficie del tambor entra exactamente en contacto con la superficie de la carretera y la rueda cortadora puede funcionar hasta la profundidad máxima según su diámetro. La rueda trasera de carretera se puede ajustar verticalmente con respecto al chasis de la máquina para proporcionar el ajuste de altura del chasis y por lo tanto el ajuste a la profundidad de corte de la rueda cortadora. La rueda principal de carretera delante del tambor de explanación bien se puede retirar totalmente o bien se puede hacer retroceder verticalmente alejándola del contacto con el suelo cuando se está usando la rueda cortadora.When the machine according to the invention is used for open a groove or ditch with the side cutter wheel, the drum will use without the esplanade cutter elements and select the minimum chassis height, such that the surface of the drum it comes in exactly contact with the road surface and the Cutter wheel can operate to maximum depth according to your diameter. The rear road wheel can be adjusted vertically with respect to the machine chassis to provide the chassis height adjustment and therefore the adjustment to the cutting depth of the cutting wheel. The main wheel of road in front of the esplanade drum can well be removed totally or it can be pushed back vertically away of ground contact when using the wheel cutter
Cuando la rueda cortadora se usa para retirar bordillos, la finalidad del miembro de contención de bordillos es ofrecer una resistencia a la tendencia de los bordillos o al menos de partes significativas de los mismos a ser levantados totalmente por los elementos cortadores. De este modo, típicamente, el extremo posterior de un bordillo habría sido reducido a fragmentos por la rueda cortadora aunque frecuentemente una parte significativa del extremo frontal habría sido levantada separándola de su asiento por la acción de elevación de los elementos cortadores, después de lo cual la parte del bordillo habría sido impulsada bien a bordo de la máquina, en donde puede atascar el tambor de explanación a medida que la máquina avanza, o bien fuera de la máquina, en donde puede representar un peligro para los trabajadores o los transeúntes. No obstante, según la invención, el miembro de contención de bordillos, el cual comprende preferentemente una pata elevable y bajable que incluye una placa o almohadilla inferior contra la cual se acoplará un bordillo en elevación o parte del mismo y se mantendrá o sujetará contra la acción de elevación de los elementos cortadores de la rueda cortadora, provocará la reducción a fragmentos de la sección de bordillo entre el extremo posterior del mismo y el miembro de contención a medida que la máquina avanza.When the cutting wheel is used to remove curbs, the purpose of the curb containment member is offer a resistance to the tendency of the curbs or at least of significant parts of them to be fully lifted by the cutting elements. Thus, typically, the extreme back of a curb would have been reduced to fragments by the cutting wheel although frequently a significant part of the front end would have been lifted away from its seat by the lifting action of the cutting elements, after which part of the curb would have been driven well aboard the machine, where you can clog the flattening drum that the machine advances, or outside the machine, where it can represent a danger to workers or bystanders. Do not However, according to the invention, the curb containment member, which preferably comprises a lifting and lowering leg that includes a plate or lower pad against which it will be attached a curb in elevation or part of it and will be held or held against the lifting action of the cutting elements of the cutting wheel, will cause the reduction to fragments of the section of curb between the back end of it and the member of containment as the machine advances.
A continuación, se describirá una máquina explanadora de carreteras según la invención, únicamente a modo de ejemplo, y haciendo referencia a los dibujos adjuntos en los cuales:Next, a machine will be described road grader according to the invention, only by way of example, and referring to the drawings attached in the which:

Volviendo inicialmente a la Figura 1, la máquina mostrada en general con la referencia 10 incluye una tapa 11 de motor, una posición 12 de conducción y ruedas delanteras orientables 13 de carretera. En la parte trasera y tal como se muestra en la posición de la Figura 1, la máquina está sostenida por ruedas 14, 15 de carretera (ver también la Figura 2) portadas en unas patas desplazables verticalmente para ajustar la altura de la parte trasera de la máquina por encima del suelo. Únicamente se muestra la pata 16 que porta la rueda 15. Las ruedas son accionadas individualmente por motores hidráulicos alimentados por una bomba hidráulica común de desplazamiento variable; un bloqueo seleccionable del diferencial proporciona la misma tracción en todas las ruedas. Un tambor 17 de explanación está montado de forma descentrada para girar con respecto a un eje lateral y una rueda cortadora lateral 18 es portada de forma desmontable y coaxialmente con respecto al tambor 17, en el lado del tambor de la máquina. La rueda cortadora porta unos cortadores 19 con puntas de carburo. Otra rueda 20 de carretera es portada en una pata retráctil verticalmente 21 montada en un soporte 22 articulado con respecto a un eje vertical. Tal como se muestra en las Figuras 1 y 2, la rueda 15 de carretera está dispuesta detrás del tambor de explanación y la pata desplazable verticalmente 16 está montada de forma pivotante con respecto a la parte trasera del chasis para proporcionar un efecto de dirección, controlado por un cilindro hidráulico 23.Returning initially to Figure 1, the machine generally shown with reference 10 includes a cover 11 of engine, driving position 12 and adjustable front wheels 13 road. In the back and as shown in the position of Figure 1, the machine is supported by wheels 14, 15 of road (see also Figure 2) carried on legs vertically scrollable to adjust the height of the part rear of the machine above ground. Only the leg 16 that carries the wheel 15. The wheels are driven individually by hydraulic motors powered by a pump common variable displacement hydraulics; a blockage Differential selectable provides the same traction in all the wheels. An esplanade drum 17 is mounted so offset to rotate with respect to a side axle and a wheel side cutter 18 is detachable and coaxially covered with respect to the drum 17, on the drum side of the machine. The Cutter wheel carries 19 cutters with carbide tips. Other road wheel 20 is carried on a retractable leg vertically 21 mounted on a support 22 articulated with respect to an axis vertical. As shown in Figures 1 and 2, wheel 15 of road is arranged behind the dock and leg drum vertically movable 16 is pivotally mounted with with respect to the rear of the chassis to provide an effect steering, controlled by a hydraulic cylinder 23.
La rueda cortadora 19 está provista de cubiertas protectoras 24, 25 (ver también la Figura 3) montadas respectivamente por el exterior y encima de la rueda y de una placa impulsada hacia abajo 26 entre la rueda 18 y el tambor 17 de explanación. La placa 26 entra en contacto con la superficie del suelo con independencia de la posición de la máquina en un plano vertical según se determina por medio de las patas desplazables verticalmente y el borde inferior de la misma se muestra en un contorno a trazos en la Figura 1. El tambor de explanación está protegido por una placa 27 de cobertura. El tambor 16 y la rueda cortadora 17 son accionados por una correa (no mostrada) que se acopla a un polipasto 28 conectado de forma accionable al tambor a través de un engranaje reductor (no mostrado).The cutting wheel 19 is provided with covers guards 24, 25 (see also Figure 3) mounted respectively on the outside and on top of the wheel and a plate driven down 26 between wheel 18 and drum 17 of esplanade The plate 26 comes into contact with the surface of the ground regardless of the machine's position in a plane vertical as determined by the movable legs vertically and the bottom edge of it is shown in a outline in strokes in Figure 1. The esplanade drum is protected by a cover plate 27. The drum 16 and the wheel cutter 17 are driven by a belt (not shown) that is attaches to a hoist 28 operably connected to the drum a through a reduction gear (not shown).
Una pata 29 que tiene su extremo inferior en forma de pie 30 es portada de manera que es elevada o bajada con el pie 30 delante de la rueda cortadora 18, controlada por el cilindro hidráulico 31. El pie 30 se muestra en la posición elevada; la referencia 30A indica la posición de descenso.A leg 29 that has its lower end in foot shape 30 is covered so that it is raised or lowered with the foot 30 in front of the cutting wheel 18, controlled by the cylinder hydraulic 31. Foot 30 is shown in the raised position; the reference 30A indicates the position of descent.
Cuando se está usando solamente para la explanación de carreteras, la rueda cortadora 18 se retira, la pata 21 se hace bajar hasta que la rueda 20 entra en contacto con el suelo, y la pata 16 se eleva para separar la rueda 15 del suelo. Para explanar el borde de la calzada, el soporte 22 se dispone tal como se muestra en las Figuras 1 y 2, con lo cual la rueda 20 queda a bordo del chasis de la máquina. Para explanar zonas separadas del borde de la calzada, el soporte 22 se hace oscilar hacia atrás con respecto a su eje de pivotamiento de tal manera que queda dispuesto junto al extremo del tambor y fuera del chasis, tal como se indica mediante las líneas 20A de trazos en la Figura 2. Las patas para las ruedas 14, 20 se ajustan en altura para llevar el tambor de explanación a la posición de funcionamiento deseada en relación con la superficie de la carretera.When it is being used only for road esplanade, the cutting wheel 18 is removed, the leg 21 is lowered until the wheel 20 comes into contact with the ground, and the leg 16 is raised to separate the wheel 15 from the ground. To explain the edge of the roadway, the support 22 is arranged such as shown in Figures 1 and 2, whereby wheel 20 is left on board the machine chassis. To explain areas separated from edge of the roadway, the support 22 is swung backwards with with respect to its pivot axis in such a way that it is arranged next to the end of the drum and outside the chassis, as indicated using the dashed lines 20A in Figure 2. The legs for the Wheels 14, 20 are adjusted in height to carry the drum of flattening to the desired operating position in relation to The road surface.
Cuando se usa para excavar una zanja o retirar bordillos, la pata 16 se hace bajar para elevar el extremo posterior de la máquina, la pata 21 se eleva a la posición mostrada en la Figura 1, y se fija la rueda cortadora 18. A continuación, la pata 16 (y también la rueda 14 de soporte de la pata) se eleva para hacer bajar la parte posterior de la máquina mientras la rueda cortadora gira, excavando el suelo hasta que se obtiene la profundidad de corte deseada; a continuación, las patas se mantienen en esta posición y la máquina avanza. Si se están retirando bordillos, la pata 29 se hace bajar hasta que la planta del pie 30 queda en la superficie superior de los bordillos o ligeramente por encima de la misma, con lo cual todos los bordillos o partes de los mismos desprendidos por la rueda cortadora y empujados hacia arriba son sujetados por el pie, y el extremo del bordillo expuesto entre el pie y la rueda cortadora se reduce a pequeños fragmentos a medida que la máquina avanza.When used to dig a ditch or remove curbs, leg 16 is lowered to raise the rear end of the machine, leg 21 is raised to the position shown in the Figure 1, and cutter wheel 18 is fixed. Next, the leg 16 (and also the leg support wheel 14) is raised to make lower the back of the machine while the cutter wheel turn, digging the ground until the depth of desired cut; then the legs are kept in this position and the machine advances. If curbs are being removed, the leg 29 is lowered until the sole of foot 30 is in the upper surface of the curbs or slightly above the same, with which all curbs or parts thereof detached by the cutter wheel and pushed up are held by the foot, and the end of the curb exposed between the foot and cutter wheel is reduced to small custom fragments that the machine advances.
