It characterizes the present invention the special constructive features that it has, which make it a simple device in its design and easy to use, achieving the purpose of releasing the seizure or blocking of the parachutes on the guides once they have been activated .
Por lo tanto, la presente invención se circunscribe dentro del ámbito de los aparatos de elevación y de manera más precisa entre los accesorios o medios de desbloqueo de los paracaídas de ascensores. Therefore, the present invention is circumscribed within the scope of lifting devices and more precisely between the accessories or means of unlocking the parachutes of elevators.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Los sistemas paracaídas de los ascensores primordialmente sirven para evitar que el ascensor ante una eventualidad o un desperfecto sea de cualquier índole, este no se caiga al vacío y evite un accidente. The parachute systems of the elevators primarily serve to prevent the elevator from any eventuality or damage being of any kind, this does not fall into a vacuum and avoid an accident.
Esta compuesto por un motor eléctrico y un freno, cada elemento es de suma importancia para el funcionamiento correcto, y se debe realizar de manera periódica tareas de mantenimiento. Estos sistemas paracaídas de los ascensores constituyen la seguridad del ascensor y funcionan en casos de emergencia, es decir cuando otros elementos de acción continua e imprescindibles para el uso fallan y ponen en riesgo al equipo y usuarios. It is composed of an electric motor and a brake, each element is of the utmost importance for proper operation, and maintenance tasks must be performed periodically. These elevator parachute systems constitute the safety of the elevator and work in cases of emergency, that is to say when other elements of continuous action and essential for use fail and put the equipment and users at risk.
Cuando el paracaídas de un ascensor se ha activado, los medios de anclaje o frenado, generalmente cuñas, producen un efecto de bloqueo del conjunto al quedar las cuñas del paracaídas gripados sobre las guías, no permitiendo el movimiento en ninguna dirección, siendo necesario tener que desmontar el paracaídas en su totalidad además de ser reemplazado, operación que es compleja y costosa en tiempo. Por lo tanto, es objeto de la presente invención desarrollar un dispositivo que debidamente montado y accionado permite desbloquear las cuñas de un paracaídas sin tener que desmontar éste, desarrollando un dispositivo como el que a continuación se describe y que queda recogido en su esencialidad en la reivindicación primera. When the parachute of an elevator has been activated, the anchoring or braking means, generally wedges, produce a blocking effect of the assembly when the parachute wedges remain on the guides, not allowing movement in any direction, being necessary to have to remove the parachute in its entirety as well as being replaced, an operation that is complex and expensive in time. Therefore, it is the object of the present invention to develop a device that, properly assembled and operated, allows the wedges of a parachute to be unlocked without having to disassemble it, developing a device such as the one described below and which is essentially included in the first claim.
