Description
Instalación de soplado para naves de limpieza de equipos de vehículos ferroviarios.Blowing installation for cleaning ships railway vehicle equipment.
La presente invención se refiere a una instalación de soplado para naves de limpieza de equipos de vehículos ferroviarios, cuya evidente finalidad es efectuar mediante soplado la limpieza de determinados equipos, concretamente motores, cofres de electrónica y equipos de aire acondicionado, que forman parte de los vehículos ferroviarios (trenes), de manera que además del soplado y consecuente realización de la limpieza, se asegura también la recogida del polvo que se origina en el proceso de soplado.The present invention relates to a Blowing installation for equipment cleaning ships railway vehicles, whose obvious purpose is to make by blowing the cleaning of certain equipment, specifically engines, electronics chests and air conditioning equipment, which they are part of railway vehicles (trains), so that In addition to blowing and consequent cleaning, also ensures the collection of dust that originates in the process of blowing.
El objeto de la invención es conseguir una total automatización en el proceso de soplado, eliminando con ello la necesidad de presencia de operarios durante dicho proceso, garantizando unos óptimos resultados.The object of the invention is to achieve a total automation in the blowing process, thereby eliminating the need for the presence of operators during this process, guaranteeing optimal results.
La invención es aplicable en el sector industrial ferroviario, para el mantenimiento de trenes.The invention is applicable in the industrial sector railway, for train maintenance.
En los vehículos ferroviarios existen determinados elementos o dispositivos tales como motores, cofres de electrónica y equipos de aire acondicionado, entre otros, en los que existe a su vez una tendencia permanente a la deposición de polvo, en el normal funcionamiento del vehículo, polvo que perjudica funcionalmente a dichos elementos o dispositivos, concretamente dificultando la disipación de calor por intercambio térmico, por lo que son necesarias operaciones de mantenimiento al respecto, consistentes en periódicas limpiezas que se suelen realizar generalmente mediante soplado.In rail vehicles there are certain elements or devices such as motors, chests of electronics and air conditioning equipment, among others, in that there is a permanent tendency to the deposition of dust, in the normal operation of the vehicle, dust that functionally damages said elements or devices, specifically hindering heat dissipation by exchange thermal, so maintenance operations are necessary when respect, consisting of periodic cleanings that are usually usually performed by blowing.
Tradicionalmente las operaciones de soplado se realizan de forma manual, por uno o varios operarios, en naves habilitadas al efecto. Los operarios, mediante pistolas de aire comprimido, desprenden el polvo retenido en los vehículos generando una atmósfera irrespirable, motivo por el cual éstos deben llevar incómodos equipos de protección individual, a la vez que las naves en las que se realiza el soplado deben estar dotadas de eficaces sistemas de renovación de aire, filtración y calefacción.Traditionally blowing operations are perform manually, by one or several operators, in ships enabled for this purpose. Operators, using air guns compressed, release the dust retained in the vehicles generating an irrespirable atmosphere, which is why they should wear uncomfortable personal protective equipment, as well as ships in which the blowing is performed they must be equipped with effective air renewal, filtration and heating systems.
Todo esto determina que el soplado sea un trabajo penoso para el operario y nocivo para su salud, a lo que hay que añadir además que, debido a esa penosidad y a la dificultad de acceder a algunos puntos de vehículo o tren, no se pueda garantizar que las operaciones de limpieza se realicen siempre con la eficacia y calidad requeridas.All this determines that blowing is a job painful for the operator and harmful to your health, to which you have to also add that, due to that hardship and the difficulty of access some vehicle or train points, cannot be guaranteed that cleaning operations are always carried out effectively and quality required.
La instalación que se preconiza ha sido concebida para resolver la problemática anteriormente expuesta, para lo cual se ha previsto que el tren o vehículos ferroviarios que se pretenden limpiar mediante soplado se hagan pasar por una nave con un foso, estableciéndose unos carriles para unos carros laterales desplazables longitudinalmente, así como otros carriles para unos carros centrales desplazables también longitudinalmente, independientemente de la vía para los vehículos ferroviarios o trenes.The installation that has been recommended has been conceived to solve the problem described above, for which it is planned that the train or railway vehicles that are pretend to clean by blowing pretend to be a ship with a pit, establishing lanes for side cars longitudinally movable, as well as other rails for some central carriages also longitudinally movable, regardless of the track for rail vehicles or trains
Los carriles para los carros laterales están situados a ambos lados de la vía de desplazamiento del tren, de manera que el desplazamiento de los carros se realiza mediante el accionamiento por servomotores o motores de pasos.The rails for the side cars are located on both sides of the train's track, of so that the displacement of the cars is done through the drive by servomotors or stepper motors.
