5 Campo de la invencion5 Field of the invention
La invencion se encuadra en el sector tecnico de las maquinas dedicadas al mantenimiento y construction de v^as ferreas, mas concretamente en lo relativo a los grupos de bateo de las maquinas bateadoras de via.The invention is part of the technical sector of machines dedicated to the maintenance and construction of railways, more specifically in relation to batting groups of road batting machines.
Antecedentes de la invencionBackground of the invention
10 El paso de los distintos vehiculos que circulan por las vias ferreas y su exposition a las condiciones meteorologicas, modifican las cualidades de la via y del resto de elementos sobre los que se asienta. Para corregir la perdida de estas cualidades y evitar la imposibilidad del uso de la via, es necesario llevar a cabo una serie de trabajos de mantenimiento. Con la tecnica existente en la actualidad, el proceso de corregir en direction10 The passage of the different vehicles that circulate on the railways and their exposure to the meteorological conditions, modify the qualities of the road and the rest of the elements on which it sits. To correct the loss of these qualities and avoid the impossibility of using the road, it is necessary to carry out a series of maintenance work. With the technique currently in existence, the process of correcting in direction
15 vertical y horizontal la via es realizado por maquinas equipadas con grupos de nivelacion y alineacion, tambien conocidos como equipos de levante y ripado. El grupo de bateo es el encargado de calzar cada traviesa en su nueva position compactando la piedra situada debajo de esta. Segun el tipo de maquina y grupo de bateo, en la actualidad es posible batear desde una a cuatro traviesas al mismo tiempo.15 vertical and horizontal the track is made by machines equipped with leveling and alignment groups, also known as lifting and ripping equipment. The batting group is in charge of fitting each crossbar in its new position by compacting the stone below it. Depending on the type of machine and batting group, it is currently possible to hit from one to four sleepers at the same time.
20 En general, los grupos de bateo existentes en la actualidad estan caracterizados por aportar un esfuerzo de cierre a los bates que penetran en la bancada de balasto y calzan las traviesas haciendo fluir las piedras bajo las mismas. Este esfuerzo tiene una componente fija, ejercida por un cilindro hidraulico y una componente oscilatoria. La solution mas habitual para generar este esfuerzo vibratorio es mediante un eje con geometria excentrica20 In general, currently existing batting groups are characterized by providing a closing effort to the bats that penetrate the ballast bench and fit the sleepers by flowing the stones under them. This effort has a fixed component, exerted by a hydraulic cylinder and an oscillatory component. The most common solution to generate this vibratory effort is through an axis with eccentric geometry
25 al que se hace girar a ciertas revoluciones para conseguir la frecuencia deseada. Existen tambien otras soluciones, como la presentada en la patente ES-2027048-B1, en la que ese esfuerzo oscilante es conseguido por accion de un sistema formado en esencia por un actuador hidraulico alimentado por medio de valvulas de distribution de alimentacion- descarga controladas en secuencia dclica por uno o mas medios distribuidores.25 which is rotated at certain revolutions to achieve the desired frequency. There are also other solutions, such as the one presented in patent ES-2027048-B1, in which this oscillating effort is achieved by the action of a system formed essentially by a hydraulic actuator fed by means of controlled supply-discharge distribution valves in public sequence by one or more distributors.
30 Existen diversas soluciones en lo referente al tiempo y forma de aplicacion de la30 There are several solutions regarding the time and form of application of the
componente vibratoria del esfuerzo del bate. Como ya se ha comentado, la solucion mas habitual para generar este esfuerzo vibratorio es mediante un eje con geometria excentrica al que se hace girar a ciertas revoluciones para conseguir la frecuencia deseada. Este sistema suele ir acompanado por un volante de inercia de grandes dimensiones, por lo que 5 la capacidad de hacer variar la frecuencia de vibracion es muy baja. Sin embargo, segun la solicitud de patente espanola P201530363, se conoce un grupo de bateo gobernado por una electrovalvula de alta frecuencia. En esta invention se establece una diferenciacion entre las frecuencias de oscilacion durante la penetration del bate en la piedra (25Hz) y la frecuencia durante el cierre de bates (35Hz). Durante el resto del ciclo desaparece la componente 10 vibratoria.vibratory component of bat effort. As already mentioned, the most common solution to generate this vibratory effort is by means of an axis with eccentric geometry which is rotated at certain revolutions to achieve the desired frequency. This system is usually accompanied by a large flywheel, so the ability to vary the frequency of vibration is very low. However, according to the Spanish patent application P201530363, a batting group governed by a high frequency solenoid valve is known. In this invention a differentiation is established between the oscillation frequencies during the penetration of the bat in the stone (25Hz) and the frequency during the closing of bats (35Hz). During the rest of the cycle the vibrating component 10 disappears.
Otra caracteristica de los grupos de bateo es la forma de adaptar la apertura de los bates para diferenciar las operaciones realizadas en zonas donde el carril descansa sobre doble traviesa, en vez de una que es lo mas habitual. Para ello, las maquinas suelen limitar la carrera del cilindro hidraulico que realizan la apertura y cierre de bates. Esta limitation suele 15 constar de un cuerpo metalico articulado sobre la camisa del cilindro de cierre de bates. Este cuerpo limita la carrera del vastago en las operaciones de traviesa simple. Cuando hay que batear una traviesa doble, un cilindro secundario retira el cuerpo articulado permitiendo al vastago alcanzar su recorrido maximo. Por la patente US-6401623-B2 se conoce un sistema para eliminar este sistema hidraulico-mecanico limitando hidraulicamente el volumen de 20 aceite que entra a la camara del cilindro en caso de bateo en traviesa simple.Another characteristic of batting groups is the way to adapt the opening of bats to differentiate the operations performed in areas where the lane rests on double sleepers, instead of one that is the most common. For this, the machines usually limit the hydraulic cylinder stroke that the bats open and close. This limitation usually consists of a metal body articulated on the sleeve of the bat closing cylinder. This body limits the rod race in simple naughty operations. When a double sleeper has to be batted, a secondary cylinder removes the articulated body allowing the rod to reach its maximum travel. From US-6401623-B2 a system is known to eliminate this hydraulic-mechanical system by hydraulically limiting the volume of oil that enters the cylinder chamber in the case of a single sleeper batting.
Description de la invencionDescription of the invention
Es necesario ofrecer una alternativa al estado de la tecnica que cubra las lagunas encontradas en la misma.It is necessary to offer an alternative to the state of the art that covers the gaps found therein.
Con este fin la presente invencion proporciona un avance en la capacidad de penetracion de 25 los grupos de bateo en el lecho de balasto, mediante la modification de los parametros que rigen la componente oscilante del esfuerzo del bate. Esto es aplicable tanto para bateo de traviesa simple como doble.To this end the present invention provides an advance in the penetration capacity of the batting groups in the ballast bed, by modifying the parameters that govern the oscillating component of the bat effort. This is applicable for both single and double sleeper batting.
Concretamente, esta invencion se refiere a un grupo de bateo para maquinas de mantenimiento ferroviario con capacidad de batear el balasto bajo las traviesas de la via, 30 simple y doble, que comprende un chasis dispuesto para ascender y descender de position mediante un cilindro, un eje principal sobre el que rotan dos cilindros interiores dispuestos para transmitir el movimiento de vibracion y cierre a unos portabates interiores, dos cilindros exteriores dispuestos para transmitir el movimiento de vibracion y cierre a unos portabatesSpecifically, this invention relates to a batting group for railway maintenance machines capable of hitting the ballast under the sleepers of the single and double track, comprising a chassis arranged to ascend and descend position by means of a cylinder, a main axis on which rotate two inner cylinders arranged to transmit the movement of vibration and closure to an internal carrier, two external cylinders arranged to transmit the movement of vibration and closure to some portabates
exteriores donde cada uno de cilindros interiores y exteriores estan gobernados por una electrovalvula de alta frecuencia configurable en tension, frecuencia y geometria de onda donde el control de dichas electrovalvulas esta dispuesto para transmitir una oscilacion primaria de alta frecuencia (f1) y una secundaria de baja frecuencia (f2).outside where each of inner and outer cylinders are governed by a high frequency solenoid valve configurable in voltage, frequency and wave geometry where the control of said solenoid valves is arranged to transmit a primary high frequency oscillation (f1) and a secondary low frequency (f2).
5 Como se puede ver, a diferencia de las soluciones anteriores, el mecanismo de la invention comprende un cilindro de vibration, con una camara central en la que el movimiento del vastago, llamado de vibracion y cierre, que esta gobernado por una electrovalvula de alta frecuencia configurable en tension, frecuencia y geometria de onda.5 As can be seen, unlike the previous solutions, the mechanism of the invention comprises a vibration cylinder, with a central chamber in which the movement of the rod, called vibration and closure, which is governed by a high solenoid valve configurable frequency in voltage, frequency and wave geometry.
Sin perdida de generalidad, esta forma de gobernar el vastago de vibracion y cierre es 10 aplicable a un cilindro compuesto de un total de tres vastagos coplanares, donde el que ocupa la position central esta gobernado por la valvula de alta frecuencia. Los dos vastagos exteriores estan orientados en sentido de trabajo contrario al central, y configuran la posicion de bateo para bateo de traviesa simple o doble.Without loss of generality, this form of governing the vibration and closing rod is applicable to a cylinder composed of a total of three coplanar rods, where the one occupying the central position is governed by the high frequency valve. The two outer rods are oriented in the opposite direction to the center, and configure the batting position for single or double sleeper batting.
La particularidad de la invencion viene dada por la adicion de una segunda componente 15 oscilatoria al movimiento del bate durante la penetration en el lecho de balasto. Para ello se dispone de dos configuraciones distintas de los parametros de control de la electrovalvula que responden a una onda cuadrada de 48Hz de frecuencia. Cada una de las dos configuraciones tiene un leve descentrado en la amplitud de la onda, de forma que una de ellas tiende a sacar el vastago y la otra a meterlo, dentro de su movimiento oscilatorio. De 20 esta forma, alimentando de manera alternativa la electrovalvula con estas dos configuraciones, se consigue un segundo movimiento oscilatorio que se superpone a la vibracion primaria de 48Hz generada por la onda cuadrada. En el caso concreto de esta invencion, este cambio de parametros se produce 10 veces por segundo, es decir, se obtiene una composition de un movimiento de alta frecuencia -48Hz- y uno de baja -10Hz-. 25 Se ha elegido un descentrado en amplitud para conseguir el desplazamiento neto hacia un lado u otro. Sin perdida de generalidad se puede conseguir este efecto manteniendo la simetria en amplitud y modificando, por ejemplo, el porcentaje de tiempo que la valvula permite el paso de aceite a una y otra camara del cilindro.The particularity of the invention is given by the addition of a second oscillatory component 15 to the movement of the bat during penetration into the ballast bed. For this, two different configurations of the control parameters of the solenoid valve are available that respond to a square wave of 48Hz frequency. Each of the two configurations has a slight offset in the amplitude of the wave, so that one of them tends to take out the rod and the other to put it, within its oscillatory movement. In this way, by feeding the solenoid valve alternatively with these two configurations, a second oscillatory movement is achieved that overlaps the primary 48Hz vibration generated by the square wave. In the specific case of this invention, this change of parameters occurs 10 times per second, that is, a composition of a high-frequency movement -48Hz- and a low -10Hz- movement is obtained. 25 An offset in amplitude has been chosen to achieve net displacement to one side or the other. Without loss of generality, this effect can be achieved by maintaining the symmetry in amplitude and modifying, for example, the percentage of time that the valve allows the passage of oil to one and another chamber of the cylinder.
La doble oscilacion horizontal de los bates se suma al descenso vertical del grupo de bateo 30 durante la penetracion en el lecho de balasto. Se ha comprobado empmcamente una notable mejora en el tiempo de penetracion y un menor desgaste del balasto. El descenso del grupo se consigue mediante los componentes habituales, es decir, guiado por un par de columnas fijas a la maquina y movido por un cilindro hidraulico, tambien fijo en su extremoThe double horizontal oscillation of the bats adds to the vertical descent of the batting group 30 during penetration into the ballast bed. A notable improvement in penetration time and reduced ballast wear have been emphatically proven. The descent of the group is achieved by the usual components, that is, guided by a pair of columns fixed to the machine and moved by a hydraulic cylinder, also fixed at its end
posterior.later.
Una vez alcanzada la profundidad de bateo deseada se detiene el descenso del grupo y se modifica la senal de la electrovalvula, pasando a una tercera configuracion de parametros. Esta configuracion corresponde tambien a una onda cuadrada, en este caso de 35Hz de 5 frecuencia, y descentrada en amplitud de forma que se favorece el avance del bate. De esta forma se consigue la superposicion de los movimientos de vibracion y cierre de bates, que se genera tradicionalmente con un movimiento lineal del vastago y una excitacion del cilindro mediante el giro de un eje excentrico.Once the desired batting depth has been reached, the descent of the group stops and the solenoid valve signal is modified, moving to a third parameter setting. This configuration also corresponds to a square wave, in this case of 35Hz of 5 frequency, and offset in amplitude so that the advance of the bat is favored. In this way the superposition of the movements of vibration and closing of bats is achieved, which is traditionally generated with a linear movement of the rod and an excitation of the cylinder by means of the rotation of an eccentric axis.
Estas y otras ventajas se ven evidentes a la luz de la descripcion detallada de la invencion.These and other advantages are evident in light of the detailed description of the invention.

La invencion se refiere a un grupo de trabajo de una maquina de mantenimiento de via ferrea. El grupo de trabajo en cuestion es el de bateo, con capacidad de operar sobre dos traviesas de forma simultanea, compactando la piedra existente debajo de cada una. Los 15 equipos y sistemas electronicos necesarios para realizar la medicion de la via y gobernar estos equipos de trabajos son similares a los usados actualmente en la tecnica y por tanto quedan fuera del alcance de esta descripcion.The invention relates to a work group of a railway maintenance machine. The task force in question is that of batting, with the ability to operate on two sleepers simultaneously, compacting the existing stone under each one. The 15 electronic equipment and systems necessary to measure the road and govern these work equipment are similar to those currently used in the technique and therefore are beyond the scope of this description.
Cada grupo de trabajo o de bateo, como se puede observar en las figuras 1, 2 y 3, se compone principalmente de un cuerpo principal, denominado chasis (12), que puede 20 ascender y descender a la posicion de trabajo, guiado por un par de columnas (13) fijas a la maquina, mediante el cilindro de bajada de chasis (14). El chasis contiene de un eje (15) principal, sobre el cual rotan dos cilindros interiores (11) del grupo de bateo, dichos cilindros (11) se componen principalmente de un vastago (3) que transmite el movimiento de vibracion y cierre a los portabates interiores (7) a traves de un eje de union (4). A su vez 25 estos portabates interiores (7) rotan sobre un eje (6) acoplado en el chasis. En la parte posterior de cada cilindro interior (11) se acopla un cilindro de vibracion exterior (10) mediante un eje de union (16). Cada cilindro exterior (10) se compone principalmente de tres vastagos, el vastago central (1) transmite la vibracion y cierre del portabate exterior (8) a traves de un eje de union (4). A su vez estos portabates exteriores (8) rotan sobre un eje (5) 30 acoplado en el chasis. Los vastagos exteriores (2) situados en la parte trasera del cilindro (10) son los encargados del posicionamiento de los portabates exteriores (8) en las configuraciones de bateo de traviesa simple (18) o doble (17). De esta manera estos vastagos permanecen fijos para minimizar el desgaste de piezas consumibles.Each work or batting group, as can be seen in Figures 1, 2 and 3, is mainly composed of a main body, called a chassis (12), which can ascend and descend to the work position, guided by a pair of columns (13) fixed to the machine, by means of the chassis lowering cylinder (14). The chassis contains a main shaft (15), on which two inner cylinders (11) of the batting group rotate, said cylinders (11) are mainly composed of a rod (3) that transmits the movement of vibration and closing to the inner bumpers (7) through a joint shaft (4). In turn, these inner bumpers (7) rotate on an axis (6) coupled to the chassis. At the rear of each inner cylinder (11) an outer vibration cylinder (10) is coupled by means of a joint shaft (16). Each outer cylinder (10) is mainly composed of three rods, the central rod (1) transmits the vibration and closing of the outer carrier (8) through a joint shaft (4). In turn, these outer bumpers (8) rotate on a shaft (5) 30 coupled to the chassis. The outer rods (2) located at the rear of the cylinder (10) are responsible for the positioning of the outer bumpers (8) in single batter (18) or double (17) batting configurations. In this way these stems remain fixed to minimize wear of consumable parts.
Cada cilindro esta comandado por su correspondiente electrovalvula de alta frecuencia (9). La figura 5 muestra la senal de excitacion de la valvula que permite conseguir el modo de penetracion reivindicado segun la invencion. Para ello se dispone de dos configuraciones distintas de parametros. La primera configuracion de parametros (20) tiene como 5 caracteristicas principales una frecuencia de vibracion f1=48Hz, y un descentrado de +50% en amplitud que favorece un desplazamiento neto positivo del bate segun el eje x, dentro de un movimiento oscilatorio de amplitud A1=6mm. De forma analoga, se dispone de una segunda configuracion de parametros (21) simetrica a la anterior con la misma frecuencia y amplitud -48Hz y 6mm-, con un descentrado de -50% en amplitud que favorece un 10 desplazamiento neto negativo del bate segun el eje x. Mediante una secuencia de alternancia entre las dos configuraciones de parametros (20 y 21) cada 0,05 segundo, se consigue la superposicion de un movimiento oscilatorio primario de f1=48Hz y A1=6mm con uno secundario de f2=10Hz y A2=16mm, debido a dicha alternancia de parametros.Each cylinder is commanded by its corresponding high frequency solenoid valve (9). Figure 5 shows the excitation signal of the valve that allows to achieve the penetration mode claimed according to the invention. For this, two different parameter settings are available. The first configuration of parameters (20) has as main 5 characteristics a vibration frequency f1 = 48Hz, and an offset of + 50% in amplitude that favors a positive net displacement of the bat according to the x axis, within an oscillatory movement of amplitude A1 = 6mm. Analogously, there is a second configuration of parameters (21) symmetrical to the previous one with the same frequency and amplitude -48Hz and 6mm-, with an offset of -50% in amplitude that favors a negative net displacement of the bat according to the x axis By means of a sequence of alternation between the two parameter configurations (20 and 21) every 0.05 second, the superposition of a primary oscillatory movement of f1 = 48Hz and A1 = 6mm is achieved with a secondary one of f2 = 10Hz and A2 = 16mm , due to said alternation of parameters.
Una vez se alcanza la profundidad de bateo deseada se altera sustituye la senal de 15 excitacion de la valvula con por una tercera configuracion de parametros (22), caracterizado por una frecuencia f3=35Hz y una amplitud descentrada +50%, de forma que el desplazamiento neto durante un ciclo es positivo, es decir, se produce el movimiento de cierre de bates.Once the desired batting depth is reached, the valve excitation signal is changed by a third parameter setting (22), characterized by a frequency f3 = 35Hz and an amplitude offset + 50%, so that the Net displacement during a cycle is positive, that is, the closing movement of bats occurs.
