Abstract
Description
Detector electrónico y medios complementarios de actuación sobre paracaídas de ascensores.Electronic detector and complementary means of performance on parachute of elevators.
La invención ahora propugnada consiste en un detector electrónico y medios complementarios de actuación sobre paracaídas de ascensores, de entre los medios de actuación sobre el sistema de bloqueo del paracaídas.The invention now advocated consists of a electronic detector and complementary means of action on elevator parachute, from among the means of action on the parachute locking system.
Caracteriza esta invención unos controles electrónicos que actúan sobre una bobina, encargada de accionar el la palanca de acuñamiento que actúa sobre el paracaídas a la menor desviación de los parámetros de control prefijados.This invention features controls electronic devices acting on a coil, responsible for operating the the wedge lever that acts on the parachute at the smallest deviation from the default control parameters.
De acuerdo con la normativa vigente, todos los ascensores deben estar dotados de medios de seguridad que impidan la caída de estos en caso de mal funcionamiento, resolviéndose convencionalmente el problema con dispositivos mecánicos diversos que, por lo general, consisten en un cable unido al sistema paracaídas, del que parte y que discurre a lo largo del recorrido del ascensor, pasando también por una polea externa, situada en la sala de máquinas, cuando el ascensor dispone de ésta.In accordance with current regulations, all elevators must be provided with safety means that prevent the fall of these in case of malfunction, resolving conventionally the problem with various mechanical devices which usually consist of a cable attached to the system parachute, from which part and which runs along the route of the elevator, also passing through an external pulley, located in the engine room, when the elevator has it.
El movimiento de ascenso o descenso de la cabina arrastra al cable y éste, a su vez, hace girar la polea, giro que se aprovecha para controlar la velocidad del ascensor de modo que, si la velocidad pasa de un límite predeterminado, la polea se bloquea con una uñeta, con lo que el cable tracciona el sistema paracaídas que desplaza en movimiento de avance los elementos de enclavamiento del paracaídas, frenando al ascensor.The movement of ascent or descent of the cabin drag the cable and it, in turn, rotates the pulley, which it is used to control the speed of the elevator so that, if the speed exceeds a predetermined limit, the pulley is Locks with a fingernail, so the cable pulls the system parachute that moves in advance the elements of parachute interlocking, braking the elevator.
Este sistema de limitación de velocidad tiene el grave inconveniente de que los componentes mecánicos actuantes sufren un grave desgaste, lo que obliga a revisiones de período corto y a substituciones de piezas con elevada frecuencia, salvo problemas de seguridad inasumibles.This speed limitation system has the serious disadvantage that the mechanical components acting they suffer serious wear, which requires period revisions short and high frequency parts substitutions, except unassuming security problems.
Por otro lado, la precisión inicial del control de la velocidad mediante la polea queda disminuida con el paso del tiempo, por el progresivo desgaste de la polea con el contínuo roce del cable, aparte de que el sistema de bloqueo de ésta mediante la uñeta no es igualmente eficaz con independencia de la velocidad adquirida por el ascensor en su caída de modo que, a alta velocidad, la uñeta no se introduce en la primera perforación disponible de la polea sino que suele saltar varias posiciones, enclavándose en una perforación más adelantada, con lo que se retrasa el accionamiento del paracaídas.On the other hand, the initial control accuracy of the speed through the pulley is diminished with the passage of time, by the progressive wear of the pulley with the continuous rubbing of the cable, apart from that the locking system of the cable by means of fingernail is not equally effective regardless of speed acquired by the elevator in its fall so that, at high speed, the nail is not introduced in the first perforation available from the pulley but usually jumps several positions, interlocking in a more advanced drilling, with what delays parachute operation.
El solicitante desconoce la existencia de detectores electrónicos y sus medios complementarios de actuación sobre el sistema de paracaídas, de las características del que ahora se propugna.The applicant is unaware of the existence of electronic detectors and their complementary means of action about the parachute system, of the characteristics of which Now he advocates.
La invención objeto de la presente memoria se refiere a un detector electrónico y unos medios de actuación sobre paracaídas de ascensores, de entre todos aquellos medios de actuación sobre el sistema convencional de bloqueo del paracaídas.The invention object of the present specification is refers to an electronic detector and means of action on elevator parachute, among all those means of action on the conventional locking system of parachute.
Caracteriza esta invención unos controles electrónicos que incorporan un frecuencímetro conectado a una diversidad de sensores de velocidad dispuestos a lo largo de los pilares que incorporan las guías del ascensor, a distancia acorde a la velocidad nominal de éste y coincidente con el espacio recorrido por el mismo durante un segundo, de modo que si transcurre un tiempo diferente de una señal de detección de paso a la siguiente, con un margen de desviación que puede prefijarse incluso en unos pocos milisegundos, esta unidad de control envía una señal al cuadro de control que actúa sobre una bobina, encargada de accionar la palanca de acuñamiento y detener éste de forma convencional al ascensor, si bien haciéndolo cuando empieza a adquirir una velocidad de caída ligeramente mayor a la habitual y no necesariamente cuando esta velocidad ha alcanzado unos valores elevados o, incluso, peligrosos.This invention features controls electronics that incorporate a frequency meter connected to a diversity of speed sensors arranged along the pillars that incorporate the elevator guides, remotely according to its nominal speed and coincident with the space traveled for the same for a second, so if a different time from one detection signal to the next, with a margin of deviation that can be preset even in some few milliseconds, this control unit sends a signal to the control panel acting on a coil, responsible for operating the wedge lever and stop it conventionally at elevator, although doing so when you start acquiring a drop speed slightly higher than usual and not necessarily when this speed has reached values high or even dangerous.
