Esencialmente, todas ellas son movidas eléctrica o hidráulicamente.Multiple embodiments of devices for moving are known passage barriers, both for vehicles and for other purposes such as level crossings or the like. Essentially, all of them They are moved electrically or hydraulically.
En el caso de tratarse de un accionamiento eléctrico, el grupo motor comprende por lo general un motorreductor y un juego de bielas, con el fin de proporcionar al brazo de la barrera un movimiento acelerado inicialmente y desacelerado en su tramo final. Asimismo, en el caso de tratarse de un accionamiento hidráulico, el correspondiente cilindro hidráulico tiende a proporcionar al brazo de barrera un movimiento sucesivamente acelerado y desacelerado.In the case of an electric drive, the group motor usually comprises a gearmotor and a set of connecting rods, in order to provide the barrier arm with a initially accelerated and decelerated movement in its final stretch. Also, in the case of a hydraulic drive, the corresponding hydraulic cylinder tends to provide the arm of barrier a successively accelerated movement and decelerated
No obstante, como que el brazo de barrera está montado sobre el mismo eje que recibe el movimiento del elemento motor, resulta en ambos casos prácticamente imposible impedir que al final de los recorridos en ambos sentidos del brazo de la barrera, se produzcan oscilaciones o vibraciones producidas por cualquier mínimo huelgo existente en la fijación del brazo de la barrera sobre el eje móvil, con el agravante de que, con el transcurso del tiempo, el citado huelgo tiende irremisiblemente a aumentar.However, as the barrier arm is mounted on the same axis that receives the movement of the motor element, results in both cases virtually impossible to prevent at the end of paths in both directions of the barrier arm, occur oscillations or vibrations produced by any minimal strike existing in fixing the barrier arm on the shaft mobile, with the aggravating fact that, over time, the said strike irremissibly tends to increase.
La presente invención tiene como finalidad lograr un dispositivo para mover barreras de paso que proporcione un acoplamiento entre el eje móvil y el brazo de la barrera prácticamente exento de huelgo y muy resistente al desgaste.The present invention aims to achieve a device to move barriers that provide a link between the movable shaft and the barrier arm virtually free of Strike and very resistant to wear.
En su esencia, el dispositivo objeto de la invención se caracteriza porque está constituido por un conjunto formado por una corona dentada y un tornillo sin fin, endentados permanentemente en posición operativa, de los que el tornillo sin fin está dotado de un elemento motor que le proporciona un movimiento giratorio sobre su eje alternativamente en ambos sentidos de giro, de modo que dicho movimiento provoca desplazamientos angulares de la corona respecto del tornillo sin fin de un valor aproximado de 90° cada uno, alternativamente en sentidos contrarios.In essence, the device object of the invention is characterized in that it is constituted by a set formed by a crown gear and a worm, permanently set in operating position, of which the worm is provided with a motor element that provides a rotating movement on its axis alternately in both directions of rotation, so that said movement causes angular displacements of the crown with respect to the worm screw of approximately 90 ° each one, alternatively in opposite directions.
Según otra característica de la presente invención, la corona dentada está dispuesta fija y el tornillo sin fin lleva acoplado rígida y coaxialmente el brazo de barrera.According to another feature of the present invention, the crown Toothed is fixed and the worm is attached rigidly and coaxially the barrier arm.

En dichos dibujos puede apreciarse que el dispositivo de que se trata, adaptado para mover un brazo 1 de barrera, está constituido por una rueda dentada 2 y un tornillo sin fin 3, endentados permanentemente en su posición operativa.In said drawings it can be seen that the device of which treats, adapted to move a barrier arm 1, is constituted by a cogwheel 2 and an endless screw 3, set permanently in its operational position.
El tornillo sin fin 3 está dotado de un elemento motor 4, que en los dibujos se trata de un electromotor coaxial al tornillo 3, el cual proporciona a este último un movimiento giratorio sobre su eje 7 alternativamente en ambos sentidos. Dicho movimiento da lugar a desplazamientos relativos angulares entre la corona 2 y el tornillo 3 de un valor aproximado de 90°, alternados en sentidos contrarios.The worm 3 is equipped with a motor element 4, which in The drawings are a coaxial electric motor to screw 3, the which provides the latter with a rotating movement on its axis 7 alternately both ways. Said movement gives rise to relative angular displacements between crown 2 and screw 3 of an approximate value of 90 °, alternated in directions contrary.
En la realización representada en las Figs. 1 y 3, la corona dentada 2 está dispuesta fija y el tornillo sin fin 3 lleva acoplado rígida y coaxialmente el brazo de barrera 1. Por el contrario, en la realización ilustrada en las Figs. 2 y 4 el tornillo sin fin 3 está dispuesto giratorio sobre su eje 7, que es fijo, y la corona dentada 2 lleva solidariamente acoplado el brazo de barrera 1 en sentido perpendicular a su eje 10.In the embodiment represented in Figs. 1 and 3, the crown Toothed 2 is fixed and the worm 3 has rigidly and coaxially coupled the barrier arm 1. By the opposite, in the embodiment illustrated in Figs. 2 and 4 on worm 3 is rotatably arranged on its axis 7, which is fixed, and toothed crown 2 has the arm attached to it of barrier 1 perpendicular to its axis 10.
El engrane permanente entre la corona 2 y el tornillo sin fin 3 se mantiene gracias a una pieza 5 de unión, constituida por un cuerpo prismático hueco de sección rectangular, dos de cuyas paredes paralelas 6 están atravesadas por el eje 7 del tornillo sin fin 3 y lo mantienen con posibilidad de giro libre mediante dos respectivos cojinetes 8, en tanto que las otras dos paredes 9, perpendiculares a las paredes 6 y algo más largas, están unidas a dichas paredes 6 y están atravesadas por los respectivos extremos del eje 10 de la corona dentada 2, que gira libremente sobre correspondientes cojinetes 11.Permanent gear between crown 2 and worm 3 it is maintained thanks to a connecting piece 5, constituted by a hollow prismatic body of rectangular section, two of whose parallel walls 6 are crossed by the axis 7 of the screw without end 3 and keep it with the possibility of free spin by two respective bearings 8, while the other two walls 9, perpendicular to walls 6 and somewhat longer, are attached to said walls 6 and are crossed by the respective ends of the shaft 10 of the crown gear 2, which rotates freely on corresponding bearings 11.
Por otra parte, dicho eje 10 de la corona 2 atraviesa asimismo las dos paredes de una horquilla 12 de soporte, sólida y amoviblemente unida a la corona 2.On the other hand, said axis 10 of the crown 2 also crosses the two walls of a support fork 12, solid and removably attached to the crown 2.
En el caso de la forma de realización de las Figs. 1 y 3, la horquilla 12 es solidaria a un poste de soporte 13, en tanto que en la forma de realización de las Figs. 2 y 4 la horquilla 12 está sólidamente unida al brazo de barrera 1 y el motor 4 está introducido en el interior del poste de soporte 13, que es hueco.In the case of the embodiment of Figs. 1 and 3, the fork 12 is integral with a support post 13, while in the embodiment of Figs. 2 and 4 the fork 12 is solidly attached to the barrier arm 1 and the motor 4 is inserted inside the support post 13, which is hole.
En las Figs. 1 y 2 se ha suprimido la pared anterior de las paredes paralelas 9, a fines de claridad de los dibujos.In Figs. 1 and 2 the anterior wall of the parallel walls 9, for the purpose of clarity of the drawings.
En el funcionamiento normal de la barrera según la realización de las Figs. 1 y 3, el conjunto formado por el motor 4, el tornillo sin fin 3 y el brazo de barrera 1, que están alineados, se mueve alrededor de la corona 2 fija, girando alrededor del eje 10 de esta última, en tanto que en la realización representada en las Figs. 2 y 4, el tornillo sin fin 3 gira sobre su eje 7 y obliga al conjunto formado por la rueda 2 y el brazo de barrera 1 a girar sobre el eje 10 de la corona.In the normal operation of the barrier according to the embodiment of Figs. 1 and 3, the assembly formed by motor 4, the screw endless 3 and the barrier arm 1, which are aligned, moves around the fixed crown 2, turning around the axis 10 of this last, while in the embodiment represented in Figs. two and 4, the worm 3 rotates on its axis 7 and forces the set consisting of wheel 2 and barrier arm 1 to rotate on the axis 10 of the crown.
En caso de avería en el elemento motor 4, por falta de energía o por cualquier otra causa, basta con liberar la unión entre la corona dentada 2 y la horquilla 12 de soporte, unión ésta que puede estar constituida por ejemplo por un simple pasador o tornillo, para que pueda hacerse girar fácilmente el conjunto de tornillo sin fin 3 y corona 2, con lo que el brazo de barrera 1 puede accionarse manualmente.In case of failure of the motor element 4, due to lack of power or for any other cause, just release the union between the toothed crown 2 and support fork 12, this joint that can be constituted for example by a simple pin or screw, so that the screw assembly can be easily rotated without end 3 and crown 2, whereby the barrier arm 1 can be operated manually.
Otra forma de liberar el accionamiento del brazo de barrera 1 podría también ser mediante el desacoplamiento de la corona 2 y el tornillo sin fin 3.Another way to release the barrier arm drive 1 it could also be by decoupling crown 2 and the worm screw 3.
