DISPOSITIVO DE DESALOJO DE VIAJEROS PARA UNIDADES DE TRAVELER EVICTION DEVICE FOR UNITS OF

FERROCARRILRAILWAY

D E S C R I P C I Ó ND E S C R I P C I Ó N

OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION

La presente invención se refiere a un dispositivo de desalojo de viajeros, que ha sido especialmente concebido para unidades de ferrocarril.The present invention relates to a passenger eviction device, which has been specially designed for railway units.

El objeto de la invención es permitir un fácil desalojo de los viajeros ante cualquier eventualidad que así lo requiera y en cualquier punto de la vía a lo largo del recorrido del tren.The object of the invention is to allow easy eviction of travelers in the event of any event that requires it and at any point along the route along the train route.

De forma más concreta el objeto de la invención es establecer medios que relacionen el nivel de la plataforma de los coches con el nivel de la vía, para permitir el fácil y cómodo descenso de los viajeros por su propio pie en situaciones excepcionales de desalojo.More specifically, the object of the invention is to establish means that relate the level of the platform of the cars with the level of the road, to allow the easy and comfortable descent of the travelers by their own foot in exceptional situations of eviction.

ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION

En las instalaciones de ferrocarril, eventualmente puede producirse una parada del tren en cualquier punto de su trayectoria, fuera de las estaciones, es decir donde no existe andén de viajeros, por un corte temporal en el suministro eléctrico, una avería u otras causas. En ocasiones, estas paradas son momentáneas, pero en otras el tiempo previsto aconseja el desalojo de los viajeros, desalojo que resulta considerablemente difícil debido al acusado nivel existente entre la plataforma de las unidades del tren y el nivel de las vías, desnivel que puede verse acentuado o disminuido por un peralte de la propia vía, por un desnivel entre la vía por la que circula el tren y la vía complementaria hacia la que debe producirse la evacuación, etc.In railroad installations, a train stop may eventually occur at any point of its path, outside the stations, that is, where there is no passenger platform, due to a temporary power failure, a breakdown or other causes. Sometimes, these stops are momentary, but at other times the expected time advises the eviction of travelers, eviction that is considerably difficult due to the accused level between the platform of the train units and the level of the tracks, unevenness that can be accentuated or diminished by a cant of the own track, by an unevenness between the route by which the train circulates and the complementary route towards which the evacuation must take place, etc.

Esto obliga a los viajeros a saltar una altura considerable o utilizar unas escaleras de mano, con el consecuente riesgo de accidentes que ello supone, maniobra que resulta imposible para personas de avanzada edad o para personas con determinadas discapacidades físicas .This forces travelers to jump a considerable height or use hand ladders, with the consequent risk of accidents that this implies, a maneuver that is impossible for elderly people or for people with certain physical disabilities.

Son conocidos dispositivos de evacuación de pasajeros desde medios de transporte de viajeros por medio de rampas tal y como pueden ser la patente española ES-2.133.092 en el que la rampa se constituye a base de pequeños tramos superpuestos en modo plegados y que cuando se extiende la rampa se despliegan unos a continuación de los contiguos o precedentes.Passenger evacuation devices are known from means of transporting passengers by means of ramps, such as the Spanish patent ES-2,133,092 in which the ramp is constituted based on small sections superimposed in folded mode and when Extends the ramp unfold ones next to the adjoining ones or precedents.

Igualmente en forma de rampa debe destacarse la también patente española ES-2.133.033 y ES-2.130.032 en el que la rampa se forma a través de dos sectores articulados entre si y desplegados con la ayuda de sendos cables laterales.Likewise, in the form of a ramp, the Spanish patent ES-2,133,033 and ES-2,130,032 must also be highlighted, in which the ramp is formed through two sectors articulated with each other and deployed with the help of two lateral cables.

Estos dispositivos de evacuación en forma de rampas tienen como limitación el ser necesario una gran longitud de rampa para evitar que la pendiente de tales rampas sobrepase un cierto valor que la haría impracticable, ya que si la pendiente es elevada las personas caerían desde la misma haciéndolas altamente peligrosas. A esto ha de añadirse como estos dispositivos han de ser colocados en los laterales de los coches ya que por los extremos es inviable al disponerse en ellos o bien las unidades tractoras o las cabinas de mando no siendo posible la colocación de tales rampas de modo longitudinal al sentido de marcha de la unidad. Incluso si se dispusieran las rampas lateralmente, serían totalmente inapropiadas en ciertas aplicaciones como túneles o subterráneos ya que lateralmente no habría sitio para la colocación de las rampas.These evacuation devices in the form of ramps have as a limitation the need for a large ramp length to prevent the slope of such ramps from exceeding a certain value that would make it impracticable, since if the slope is high people would fall from it making them highly dangerous To this must be added how these devices have to be placed on the sides of the cars and that at the ends it is unfeasible when either the tractor units or the control cabins are arranged in them, it being not possible to place such ramps longitudinally to the direction of operation of the unit. Even if the ramps were arranged laterally, they would be totally inappropriate in certain applications such as tunnels or underground since laterally there would be no room for ramp placement.

Por este motivo son apropiados los dispositivos de evacuación mediante escaleras como ocurre en la patente norteamericana US-4, 583,466 que dispone lateralmente de una escalera de evacuación que en situación de reposo o inactividad permanece plana al piso del coche y que mediante un mecanismo lateral de guías correderas provoca un despliegue de los peldaños para la evacuación de las personas. Este dispositivo es apropiado cuando el desnivel es relativamente pequeño, además de tener el inconveniente de que desde la posición de plegado hasta la de inicio del despliegue esa zona no debe ser ocupada ya que podría provocar accidentes en los viajeros, lo cual resulta difícilmente controlable cuando se intenta evacuar un vehículo en situación de emergencia .For this reason, evacuation devices by stairs are appropriate, as is the case in US-4, 583,466, which has an evacuation ladder on the side, which remains flat on the floor of the car when it is at rest or inactivity, and through a lateral mechanism Sliding guides causes a deployment of the steps for the evacuation of people. This device is appropriate when the slope is relatively small, in addition to having the disadvantage that from the folding position to the start of the deployment that area should not be occupied since it could cause accidents in travelers, which is difficult to control when Attempts to evacuate a vehicle in an emergency situation.

Es también conocida la patente norteamericana US- 4.216.725 que resulta ser una simple escalera que en posición de plegado viene a realizar la función de puerta .It is also known US patent 4,216,725 which turns out to be a simple ladder that in the folded position comes to perform the door function.

Por último debe ser mencionada la patente norteamericana US-4.615.275 que como en el documento anterior, las escaleras de evacuación cuando están plegadas hacen la función de puerta de cierre del coche. DESCRIPCIÓN DE LA INVENCIÓNFinally, the US patent US-4,615,275 must be mentioned that, as in the previous document, the evacuation stairs, when folded, act as the closing door of the car. DESCRIPTION OF THE INVENTION

Es propósito de la invención realizar un dispositivo de evacuación o desalojo de viajeros para unidades de ferrocarril en los que se necesite un pequeño espacio para el desplegado de este dispositivo de evacuación, optándose por un dispositivo de evacuación en forma de escalera.It is the purpose of the invention to carry out a passenger evacuation or eviction device for railway units in which a small space is needed for the deployment of this evacuation device, opting for a stair-shaped evacuation device.

Es también propósito de la invención disponer de un dispositivo adaptado a una gama muy amplia de alturas de evacuación desde el coche hasta la calzada de evacuación y que se adapte regularmente a esa altura.It is also the purpose of the invention to have a device adapted to a very wide range of evacuation heights from the car to the evacuation road and that is regularly adapted to that height.

Es propósito de la invención disponer de un dispositivo que se adapte regularmente a la posible inclinación del coche o de la superficie de evacuación.It is the purpose of the invention to have a device that regularly adapts to the possible inclination of the car or the evacuation surface.

Es propósito de la invención constituirse por mecanismo autónomo con y sin automatismos y que no requiera suministro de energía para su funcionamiento sino que el plegado y desplegado pueda llevarse a cabo manualmente por parte de los viajeros en caso de emergencia .It is the purpose of the invention to be constituted by autonomous mechanism with and without automatisms and that does not require energy supply for its operation but that folding and unfolding can be carried out manually by travelers in case of emergency.

Es por último propósito de la invención el quedar dicho dispositivo integrado en el propio vehículo quedando el mismo oculto tanto desde el exterior como desde el interior del vehículo.It is for the last purpose of the invention to keep said device integrated in the vehicle itself being the same hidden both from the outside and from inside the vehicle.

El dispositivo de desalojo de viajeros que la invención propone resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, de manera que ante una eventualidad del tipo anteriormente citado permite establecer una escalera de longitud regulable que salve el desnivel citado, bien hacia la vía o hacia el andén de servicio, según el caso, y con un accionamiento totalmente manual o motorizado (utilizando reservas de energía del vehículo) .The passenger eviction device that the invention proposes solves in a fully satisfactory manner the aforementioned problem, so that in the event of an event of the aforementioned type it allows to establish a ladder of length adjustable to save the above-mentioned slope, either towards the track or towards the service platform, as the case may be, and with a fully manual or motorized drive (using vehicle power reserves).

Para ello y de forma más concreta el dispositivo, integrado entre la pared lateral del coche y el revestimiento interior del mismo, se materializa en una puerta exterior, abisagrada por su borde superior, con un cierre inferior tipo gatillo liberable mediante una palanca de accionamiento manual, y asistida por cualquier medio mecánico que tienda a la apertura manual de la misma, y una puerta interior, preferentemente de tipo corredera, dotada de un cierre de cremona accionado por un cuadradillo, estableciéndose entre ambas puertas una cámara en la que se establece el dispositivo de desalojo propiamente dicho, materializado a su vez en una escalera, con dos tramos telescópicos, basculante por su zona inferior y provista en su extremidad libre de al menos un cable lateral que enrolla sobre una polea superior, montada sobre un eje transversal y asistidas por un rodillo dentado con una maneta de bloqueo, de manera que el accionamiento manual de dicha maneta desbloquea el rodillo dentado y permite un abatimiento amortiguado de la escalera tras un ligero empuje frontal sobre la misma.For this, and more specifically, the device, integrated between the side wall of the car and the inner lining of the car, is embodied in an exterior door, hinged by its upper edge, with a lower trigger-type closure releasable by means of a manually operated lever , and assisted by any mechanical means that tends to the manual opening of the same, and an interior door, preferably of sliding type, equipped with a cremone bolt operated by a square, establishing between both doors a chamber in which the eviction device itself, materialized in turn on a ladder, with two telescopic sections, tilting on its lower area and provided at its free end with at least one lateral cable that coils on an upper pulley, mounted on a transverse axis and assisted by a toothed roller with a locking handle, so that the manual operation of said handle unlocks the toothed roller Do and allows a cushioned depression of the ladder after a slight frontal thrust on it.

Un segundo gatillo de bloqueo relaciona los dos tramos de escalera, de manera que actuando o no sobre el mismo la escalera se extenderá o no en función de las necesidades específicas de cada caso, es decir en función del desnivel existente entre la plataforma del coche y el nivel de las vías o del andén de servicio.A second locking trigger relates the two flights of stairs, so that acting on it or not the ladder will be extended or not depending on the specific needs of each case, that is, depending on the difference between the car platform and the level of the tracks or service platform.

Una manivela permite actuar sobre el rodillo dentado para recogida de los cables y consecuente recogida de la escalera, al término de la utilización del dispositivo .A crank allows to act on the roller Toothed for collecting the cables and consequent collection of the ladder, at the end of the use of the device.

La recogida también puede producirse por un medio motorizado .Collection can also occur by motorized means.

(1) definida entre la pared externa del coche y el revestimiento interno del mismo, concretamente entre una puerta exterior (2) y una puerta interior (3) , se materializa en una escalera (4) , telescópica, a base de dos sectores (4-4'), el primero de ellos montado basculantemente a través de un eje (5) sobre la estructura del coche y el segundo (4 ' ) deslizante en el seno del primero, para permitir el deslizamiento o desplazamiento relativo de un tramo de escalera con respecto al otro, rematándose el tramo deslizante (4'), por su extremidad libre, con un cable lateral (7) que relaciona la extremidad libre de la escalera (4) con una polea (8) establecida en la extremidad superior de la cámara (1) y asistida por un rodillo dentado (9) con el que colabora una maneta (10) provista de un gatillo de bloqueo que, mediante su liberación, permite el despliegue de la escalera por gravedad, asimismo mediante una manivela o con un medio motorizado, permite realizar el proceso de recogida.(1) defined between the external wall of the car and the internal lining of the car, specifically between an exterior door (2) and an interior door (3), is materialized in a ladder (4), telescopic, based on two sectors ( 4-4 '), the first of them mounted tiltingly through an axle (5) on the structure of the car and the second (4') sliding inside the first, to allow the sliding or relative displacement of a section of ladder with respect to the other, finishing the sliding section (4 '), at its free end, with a lateral cable (7) that relates the free end of the ladder (4) with a pulley (8) established at the upper extremity of the chamber (1) and assisted by a toothed roller (9) with which a handle (10) provided with a trigger of blocking that, by its release, allows the deployment of the ladder by gravity, also by means of a crank or with a motorized means, allows the collection process to be carried out.

Estando los dientes del rodillo (9) adecuadamente configurados para permitir el giro del mismo en sentido de recogida del cable (7) con la colaboración de una manivela (11) , fijable junto a dicho rodillo, saltando el gatillo de la maneta (10) sobre sus dientes, y sirviendo de bloqueo en sentido contrario.The roller teeth (9) being properly configured to allow the rotation of the same in the direction of collecting the cable (7) with the collaboration of a crank (11), fixed next to said roller, by jumping the trigger of the handle (10) over your teeth, and serving as a block in the opposite direction.

Un segundo gatillo (20) permite el desbloqueo de los dos tramos (4-4') de escalera, cuando es necesaria la extensión telescópica de la misma, como en el caso representado en la figura 2.A second trigger (20) allows the unblocking of the two sections (4-4 ') of the ladder, when the telescopic extension thereof is necessary, as in the case represented in Figure 2.

La puerta exterior (2) es basculante sobre la estructura del coche a través de su borde superior, colaborando con la misma un amortiguador (12) que tiende a la apertura automática y amortiguada de la misma, cuando ésta se desbloquea mediante una palanca inferior (13) basculante sobre un eje (14) y rematada en un gancho (15) de bloqueo sobre un tetón (16) .The outer door (2) is tilted on the structure of the car through its upper edge, collaborating with it a shock absorber (12) that tends to the automatic and damped opening of the same, when it is unlocked by a lower lever ( 13) tilting on a shaft (14) and topped on a hook (15) locking on a stud (16).

Por su parte la puerta interior (3) se mantendrá estable en situación de cierre con la colaboración de cualquier medio convencional apropiado, preferentemente mediante un cierre de cremona (17) .For its part, the inner door (3) will remain stable in a closed situation with the collaboration of any appropriate conventional means, preferably by means of a cremone bolt (17).

De acuerdo con la estructuración descrita, el funcionamiento del dispositivo es el siguiente:According to the structuring described, the operation of the device is as follows:

Tras la apertura de la puerta interior (3) , actuando a través de un cuadradillo sobre el cierre de cremona (17) , se procede a la basculación ascendente de la palanca (13) para liberación de la puerta exteriorAfter opening the inner door (3), acting through a square on the cremone bolt (17), we proceed to the upward tilt of the lever (13) for releasing the outer door

(2), que mediante un amortiguador (12) se abre por efecto de una presión ligera sobre la escalera que a su vez actúa sobre la puerta, provocando la apertura de la misma.(2), which by means of a shock absorber (12) is opened by the effect of light pressure on the ladder which in turn acts on the door, causing it to open.

Inmediatamente a continuación se actúa sobre la maneta (10) que libera el rodillo (8) . Esto permite el abatimiento y descenso de la escalera por gravedad y con la ayuda de otro amortiguador, quedando en situación estándar. En caso de precisar más longitud de escalera, se libera el gatillo (11) que permite el desarrollo adicional telescópico de la misma, en función de la longitud de escalera (4-4') que sea necesaria, con lo que la extremidad libre de la escalera (4) se sitúa a nivel de la vía adyacente (18) como en el ejemplo de la figura l o a nivel del andén auxiliar (19) como en el ejemplo de la figura 2.Immediately thereafter, the lever (10) that releases the roller (8) is actuated. This allows the lowering and lowering of the ladder by gravity and with the help of another shock absorber, remaining in a standard situation. If more ladder length is required, the trigger (11) is released, which allows the telescopic additional development of it, depending on the ladder length (4-4 ') that is necessary, so that the free end of the ladder (4) is located at the level of the adjacent track (18) as in the example of the figure at the level of the auxiliary platform (19) as in the example of figure 2.

Concluida la evacuación, la manivela (11) permite la recogida de la escalera (4-4') mediante giro del rodillo dentado (9) , procediéndose finalmente al cierre de la puerta exterior (2) y de la puerta interior (3) . Once the evacuation is finished, the crank (11) allows the ladder (4-4 ') to be picked up by turning the toothed roller (9), finally closing the outer door (2) and the inner door (3).
