[0001] The present invention refers to a lifting platform for loading and unloading cylinders, for example, gas cylinders of different sizes and / or loading trolleys, commonly called "mares", which allows carrying out said tasks from a high place, such as a transport vehicle or below ground level, such as a subway, alone, always protecting the safety and health of the operator by avoiding direct contact with the weight associated with the work in question and complying with cargo transportation regulations, among other associated benefits.

Además, la plataforma de elevación comprende una superficie de carga para recibir el cilindro y/o el carro de carga, la cual a su vez comprende al menos dos pestañas, ubicadas una en cada costado de la superficie de carga, para evitar que el cilindro y/o el carro de carga se desplacen hacia dichos costados. [0002] The lifting platform of the invention essentially comprises at least one profile attached to a shaft that rotates by means of a first rotation device, an extendable working device, which allows vertical movement to raise or lower the cylinder and / or or the loading cart; at least two crossbars for attaching the extendable work device to the shaft and a drive unit, which drives the operation of the extendable work device. In addition, the lifting platform comprises a loading surface to receive the cylinder and / or the loading trolley, which in turn comprises at least two tabs, located one on each side of the loading surface, to prevent the cylinder and / or the loading trolley moves towards said sides.
[0003] De manera preferente, la plataforma de elevación además comprende al menos un brazo unido a la estructura principal, que asegura al cilindro y/o al carro de carga de posibles desplazamientos en la dirección en que se carga/descarga el cilindro y/o carro de carga al o desde la plataforma. ANTECEDENTES [0003] Preferably, the lifting platform further comprises at least one arm attached to the main structure, which ensures the cylinder and / or the loading trolley of possible movements in the direction in which the cylinder is loaded / unloaded and / or loading trolley to or from the platform. BACKGROUND
[0004] En la actualidad existe un creciente interés en mejorar las condiciones de seguridad de las personas que deben trabajar transportando cargas pesadas, ya sea para disminuir el riesgo de lesiones o accidentes o para reducir el número de personas involucradas en el proceso. [0004] There is currently a growing interest in improving the safety conditions of people who must work carrying heavy loads, either to decrease the risk of injury or accidents or to reduce the number of people involved in the process.
[0005] En este contexto, y específicamente en el campo de los cilindros de gas, históricamente las labores de carga y descarga han sido realizadas por personas destinadas a realizar estas tareas de manera repetitiva. Esto conlleva una serie de problemas, tales como accidentes o lesiones en el tiempo. Para evitar estos problemas, es que en la actualidad existen varias soluciones destinadas a evitar el esfuerzo físico de los operarios y en lo posible a disminuir la cantidad de personas involucradas en estas labores. Estas soluciones implican generalmente plataformas o grúas, en las cuales se dispone el cilindro a cargar/descargar para luego, mediante algún sistema que provea movimiento a la plataforma o grúa, desplazar el cilindro a la altura deseada. Este tipo de soluciones, si bien resuelven el problema de evitar el contacto directo de las personas con las cargas, no se hace cargo de otras problemáticas asociadas, como, por ejemplo, el desplazamiento de los cilindros hasta o desde las plataformas o grúas, para lo cual es necesaria la utilización de carros de carga. [0005] In this context, and specifically in the field of gas cylinders, historically the loading and unloading tasks have been carried out by people destined to perform these tasks repeatedly. This involves a number of problems, such as accidents or injuries over time. To avoid these problems, there are currently several solutions aimed at avoiding the physical effort of the operators and, as far as possible, reducing the number of people involved in these tasks. These solutions generally involve platforms or cranes, in which the cylinder to be loaded / unloaded is arranged, and then, by means of some system that provides movement to the platform or crane, moves the cylinder to the desired height. Although these solutions solve the problem of avoiding direct contact of people with loads, they do not take care of other associated problems, such as, for example, the movement of cylinders to or from platforms or cranes, for which is necessary the use of loading carts.
[0006] Por esto, es que para todas las soluciones existentes se hace necesaria la disposición de un carro de carga en las dos alturas en las cuales se desplazará el cilindro o el bajar/subir el mismo carro de carga, generalmente por los operarios, lo cual trae nuevamente el problema del traslado de cargas mediante personas. Por lo tanto, se hace necesario un sistema que sea capaz de movilizar una carga, tal como un cilindro de gas, en conjunto con un carro de carga, lo cual elimina definitivamente la posibilidad de que el o los operarios tengan que interactuar con cargas, además de permitir el uso de un solo carro de carga para toda la operación de carga/descarga. [0007] En el ámbito de las patentes existen soluciones que apuntan a evitar el traslado de cargas mediante los operarios. Por ejemplo, el modelo de utilidad CN203543777U describe un sistema de carga/descarga con una plataforma cuya rotación es mediante un sistema de bisagras, que proporcionan rotación sobre un eje horizontal dispuesto en sentido transversal a la superficie de carga del vehículo, es decir, en donde el cilindro de gas que se dispone sobre la plataforma del sistema pasa de una posición vertical en el vehículo a una posición horizontal sobre el suelo, aprovechando la capacidad de girar del cilindro tanto para descargarlo al suelo como para subirlo desde el suelo a la plataforma. En este sentido, el sistema descrito por este documento difiere de la presente invención en la construcción y sofisticación del mismo, y principalmente en que este documento propone una elevación dada por el mismo giro de la plataforma, pivotando la misma sobre el borde unido al vehículo. En cambio, el sistema de la invención divulgada en esta solicitud propone una estructura de levante especial y una plataforma que gira sobre un eje vertical, manteniendo siempre el cilindro en posición vertical, comprendiendo una construcción completamente diferente a lo divulgado por el documento en CN203543777U. [0006] For this reason, for all the existing solutions, it is necessary to have a loading trolley at the two heights in which the cylinder will move or lower / raise the same loading trolley, generally by the operators, which again brings the problem of moving loads by people. Therefore, a system is needed that is capable of mobilizing a load, such as a gas cylinder, in conjunction with a loading cart, which definitively eliminates the possibility that the operator or operators have to interact with loads, in addition to allowing the use of a single loading trolley for the entire loading / unloading operation. [0007] In the field of patents, there are solutions that aim to avoid the transfer of loads by operators. For example, the utility model CN203543777U describes a loading / unloading system with a platform whose rotation is by means of a hinge system, which provide rotation on a horizontal axis arranged transverse to the vehicle's loading surface, that is, in where the gas cylinder that is placed on the platform of the system goes from a vertical position in the vehicle to a horizontal position on the ground, taking advantage of the ability to rotate the cylinder both to discharge it to the ground and to raise it from the ground to the platform . In this sense, the system described by this document differs from the present invention in its construction and sophistication, and mainly in that this document proposes a lift given by the same rotation of the platform, pivoting it on the edge attached to the vehicle . Instead, the system of the invention disclosed in this application proposes a special lifting structure and a platform that rotates on a vertical axis, always keeping the cylinder in a vertical position, comprising a completely different construction from that disclosed in the document in CN203543777U.
[0008] Otro ejemplo es el divulgado en la solicitud de patente E1S2005002769, que describe una plataforma que puede ser montada sobre un vehículo, ya sea aprovechando una conexión estándar de remolque, mediante una fijación especial por rieles en la superficie de carga o con una estructura pivotante fija a la superficie de carga, permitiendo la elevación de la carga y el giro de la plataforma que sostiene la misma tanto para operaciones de descarga como de carga, manteniendo la carga, por ejemplo un cilindro, siempre en la misma posición, en donde el giro de la plataforma es sobre un eje vertical. En este caso, la diferencia que existe entre la presente invención y la plataforma descrita en el documento EÍS2005002769, radica en la capacidad de la primera de acoplar carros de carga manuales, como las denominadas “yeguas”, sobre la plataforma, comprendiendo esta una base de levante especialmente diseñada para recibir dicho carro de carga y elevarlo junto con el cilindro de gas, para usar el mismo carro de carga sobre la superficie de carga del vehículo. Si bien, a partir de lo descrito en este documento, existiría la posibilidad de montar el carro de carga con el cilindro de gas, ninguna de las plataformas divulgadas en dicho documento describe una base de carga especialmente diseñada para recibir en forma segura dicho carro de carga, como si lo hace la presente invención, incrementando el beneficio sobre las plataformas de levante conocidas. [0008] Another example is the one disclosed in patent application E1S2005002769, which describes a platform that can be mounted on a vehicle, either taking advantage of a standard trailer connection, by means of special fixing by rails on the loading surface or with a Pivoting structure fixed to the loading surface, allowing the lifting of the load and the rotation of the platform that supports it for both unloading and loading operations, keeping the load, for example a cylinder, always in the same position, in where the rotation of the platform is on a vertical axis. In this case, the difference that exists between the present invention and the platform described in document EÍS2005002769, lies in the ability of the first to couple manual loading carts, such as the so-called "mares", on the platform, this comprising a base lift specially designed to receive said loading trolley and lifting it together with the gas cylinder, to use the same loading trolley on the vehicle's loading surface. Although, from what is described in this document, there would be the possibility of mounting the loading trolley with the gas cylinder, none of the platforms disclosed in said document describe a charging base specially designed to safely receive said loading trolley. loads, as if the present invention does, increasing the benefit on the known lifting platforms.
[0009] Por lo tanto, resulta necesario contar con un sistema capaz de trasladar una carga, tal como un cilindro de gas en conjunto con su respectivo carro de carga en forma segura, evitando posibles daños en el cilindro, permitiendo además usar el carro de carga tanto en operaciones sobre el suelo como en operaciones sobre la superficie de carga de, por ejemplo, un vehículo y que, al mismo tiempo, proporcione seguridad al operario, disminuyendo los riesgos de accidentes o lesiones. [0009] Therefore, it is necessary to have a system capable of transporting a load, such as a gas cylinder together with its respective load car, in a safe way, avoiding possible damage to the cylinder, also allowing the use of the loading both in ground operations and in operations on the load surface of, for example, a vehicle and that, at the same time, provides safety to the operator, reducing the risk of accidents or injuries.

[0010] The invention relates to a lifting platform for loading and unloading of cylinders and / or loading trolleys in transport vehicles or in any place that requires the movement of loads from one height to another, which allows these tasks to be carried out alone and without the need to directly load any of these loads (cylinder and / or loading trolley), reducing the risk of injury or accidents during operation, in addition to avoiding having to use a different loading trolley in each one of the phases of the operation (loading and unloading).

Furthermore, it is observed from these figures an extensible working device (40), such as a double effect hydraulic cylinder, which allows vertical movement to raise or lower a cylinder and / or a loading trolley; at least two steel crossbars (24, 25), to join the extensible working device (40) to the shaft (30); a loading surface (60), to receive the cylinder (10) and / or the loading trolley (11), wherein the loading surface (60) in turn comprises: at least two tabs (61, 62), one located on each side of the loading surface (60), to secure a loading trolley to the loading surface and to prevent the cylinder (10) and / or the loading trolley (11) from moving towards said sides; and a tab (63) at its front end, which serves as a guide when the loading trolley approaches the loading surface (60).
[0031] A partir de las figuras 1 A, IB y 1C se aprecia también que la plataforma de elevación (1) comprende un brazo (70) de acero unido al dispositivo de trabajo extensible (40), que asegura al cilindro (10) y/o al carro de carga (11) de posibles desplazamientos en la dirección en que se carga/descarga el cilindro (10) y/o carro de carga (11) a o desde la plataforma de elevación (1); un dispositivo de articulación (71), tal como una bisagra, ubicada entre uno de los extremos del brazo (70) y el dispositivo de trabajo extensible (40), que permite la rotación del brazo (70) respecto de su punto de fijación en el dispositivo de trabajo extensible (40); una manilla (27), que ayuda al accionamiento, por parte del operario, de los dispositivos de rotación (31, 32); unas líneas de comunicación (41, 42), las cuales, en una modalidad preferente, conducen líquido hidráulico desde la unidad de accionamiento para el funcionamiento del dispositivo de trabajo extensible (40); y una botonera o control remoto (80), que permite controlar el dispositivo de trabajo extensible (40) cuando está en funcionamiento a través de la unidad de accionamiento. [0031] From Figures 1 A, IB and 1C it is also seen that the lifting platform (1) comprises a steel arm (70) attached to the extensible working device (40), which secures the cylinder (10) and / or to the loading trolley (11) of possible movements in the direction in which the cylinder (10) and / or loading trolley (11) is loaded / unloaded to or from the lifting platform (1); an articulation device (71), such as a hinge, located between one of the ends of the arm (70) and the extendable working device (40), which allows the rotation of the arm (70) with respect to its fixation point in the extensible working device (40); a handle (27), that it helps the operation, by the operator, of the rotation devices (31, 32); communication lines (41, 42), which, in a preferred embodiment, carry hydraulic fluid from the drive unit for the operation of the extensible working device (40); and a keypad or remote control (80), which allows controlling the extensible work device (40) when it is in operation through the drive unit.
[0032] En las figuras 2A a 2C se enseña en detalle la superficie de carga (60), en donde se aprecia la disposición de las pestañas (61, 62), las cuales se encuentran en los costados de la superficie de carga (60) y a una altura mayor que esta, para asegurar el cilindro junto con el carro de carga. Además, se observa la lengüeta (63), la cual tiene como función servir de guía para el carro de carga al momento de realizar las labores de carga o descarga de este. Dichas pestañas (61, 62) y/o dicha lengüeta (63) pueden estar unidas al cuerpo de la superficie de carga (60), por ejemplo, mediante soldadura, o pueden estar fabricadas en forma integral con la misma. Todos estos componentes son fabricados en acero en la configuración preferente descrita en estas figuras. [0032] Figures 2A to 2C show the loading surface (60) in detail, showing the arrangement of the flanges (61, 62), which are located on the sides of the loading surface (60). ) and at a height higher than this, to secure the cylinder together with the loading trolley. In addition, the tab (63) is observed, which has the function of serving as a guide for the loading trolley at the time of loading or unloading it. Said tabs (61, 62) and / or said tab (63) may be attached to the body of the loading surface (60), for example, by welding, or may be integrally manufactured therewith. All of these components are made of steel in the preferred configuration described in these figures.
[0033] En relación con las figuras 3A y 3B, en ellas se enseña la colocación del cilindro de gas (10) en conjunto con un carro de carga (11) en la plataforma de elevación (1), el cual está fijo vertical y horizontalmente sobre la superficie de enganche (12) y de trabajo (13) de la parte trasera de un vehículo motorizado. Específicamente en la figura 3B se observa con mayor detalle la superficie de carga (60) y el carro de carga (11) subiendo a ella, en donde se aprecia la labor que cumple la lengüeta (63) en el momento de subir el carro a la plataforma (60), sirviendo de guía durante dicho proceso, para que el carro no se desbalancee, disminuyendo el riesgo de caídas. Además, se enseñan las pestañas (61, 62), las cuales tienen el largo suficiente para no chocar con el borde de la base del carro de carga, la cual queda por debajo de dichas pestañas. [0034] Respecto a las figuras 4A y 4B, estas describen el mismo proceso que las figuras 3A y 3B, pero en el momento en donde el cilindro (10) junto con el carro de carga (11) están ya dispuestos en la plataforma de elevación (1). En la figura 4B se observa como las pestañas (61, 62) quedan ubicadas sobre la base del carro de carga (11) y por los costados del cilindro (10), lo cual entrega seguridad al momento del traslado, disminuyendo los riesgos de movimientos laterales y frontales de las cargas y evitando que el cilindro (10) pierda su centro con respecto al carro de carga (11), lo cual, de ocurrir, podría hacer que el cilindro (10) caiga del carro de carga (11) al momento de desacoplarlo de la plataforma de elevación (1). [0033] In relation to Figures 3A and 3B, they show the placement of the gas cylinder (10) in conjunction with a loading trolley (11) on the lifting platform (1), which is fixed vertically and horizontally on the hooking (12) and working (13) surface of the rear of a motor vehicle. Specifically, in figure 3B, the loading surface (60) and the loading trolley (11) can be seen climbing in greater detail, where the work carried out by the tongue (63) when the carriage is raised to the platform (60), serving as a guide during said process, so that the trolley does not unbalance, reducing the risk of falls. In addition, the tabs (61, 62) are shown, which are long enough not to collide with the edge of the base of the loading carriage, which is below said tabs. [0034] With respect to Figures 4A and 4B, these describe the same process as Figures 3A and 3B, but at the moment where the cylinder (10) together with the loading carriage (11) are already arranged on the platform of elevation (1). In figure 4B it is observed how the tabs (61, 62) are located on the base of the loading carriage (11) and on the sides of the cylinder (10), which provides security at the time of transfer, reducing the risk of movement side and front of the loads and preventing the cylinder (10) from losing its center with respect to the loading carriage (11), which, if it occurs, could cause the cylinder (10) to fall from the loading carriage (11) when time to uncouple it from the lifting platform (1).
[0035] En las figuras 5 A y 5B se enseña el funcionamiento del brazo (70) de la plataforma de elevación (1), en sus posiciones abierta y cerrada, lo cual se realiza a través de un dispositivo de articulación (71), tal como una bisagra. El brazo (70) tiene como función evitar que el cilindro [0035] Figures 5 A and 5B show the operation of the arm (70) of the lifting platform (1), in its open and closed positions, which is carried out through an articulation device (71), such as a hinge. The function of the arm (70) is to prevent the cylinder
(10) y el carro de carga (11) tengan desplazamientos en la dirección en que se carga/descarga el cilindro (10) y/o carro de carga (11) al o desde el sistema (1). Dicho brazo (70) tiene forma de “C” en su configuración preferente, envolviendo tanto el cilindro (10) como el carro de carga(10) and the loading trolley (11) have displacements in the direction in which the cylinder (10) and / or loading trolley (11) is loaded / unloaded to or from the system (1). Said arm (70) has a "C" shape in its preferred configuration, wrapping both the cylinder (10) and the loading trolley
(11). En otras configuraciones, el brazo (70) puede tener una forma curva o de garfio, o cualquier forma que sea capaz de cubrir tanto el cilindro (10) como el carro de carga (11). (eleven). In other configurations, the arm (70) can have a curved or hook shape, or any shape that is capable of covering both the cylinder (10) and the loading carriage (11).
[0036] Además, en las figuras 5A Y 5B se muestran las manillas (26, 27), las cuales ayudan a la rotación del cilindro (10) y/o el carro de carga (11) en 90° respecto del eje (30), para dejarlo en posición para descenderlos del vehículo. Esto se aprecia de mejor forma en la figura 6 A, en donde se observa el cilindro (10) junto con el carro de carga (11) en una posición fuera del vehículo, listos para ser descendidos al suelo. El accionamiento de estas manillas lo realiza el operador a cargo del trabajo, lo cual no conlleva ningún esfuerzo físico considerable, dada la ayuda que brindan los dispositivos de rotación (31, 32). [0037] Una vez que el cilindro (10) y el carro de carga (11) están montados en la plataforma de elevación (1), con el brazo (70) cerrado, se opera el dispositivo de trabajo extensible (40), que en la configuración preferente corresponde a un cilindro hidráulico de doble efecto, el cual funciona a través del fluido de trabajo proporcionado por la unidad de accionamiento (50), a través de las líneas de comunicación (41, 42), tal como se observa en la figura 6B. La energización de la unidad de accionamiento (50) se produce a través de una batería externa o de manera preferente utilizando la batería del vehículo en donde se dispone la plataforma (1), mediante un cable de energización (51). Las funciones del dispositivo de trabajo extensible (40) se pueden controlar a través de la botonera o control remoto (80), para elevar o descender la superficie de carga (60) desde el vehículo hasta la superficie de trabajo (13). Finalmente, en caso de que se realice una maniobra de descenso de la superficie de carga (60), el operario libera el brazo (70) y procede a la descarga del cilindro (10) junto con el carro de carga (11). En otra modalidad de la presente invención, el giro del eje se realiza de manera automática, utilizando como fuente de energía a la unidad de accionamiento (50) o al motor del vehículo. [0036] Furthermore, in figures 5A and 5B the handles (26, 27) are shown, which help the rotation of the cylinder (10) and / or the loading carriage (11) in 90 ° with respect to the axis (30 ), to leave it in position to lower them from the vehicle. This is best seen in Figure 6A, where the cylinder (10) is seen together with the loading trolley (11) in a position outside the vehicle, ready to be lowered to the ground. The actuation of these handles is carried out by the operator in charge of the work, which does not entail any considerable physical effort, given the help provided by the rotation devices (31, 32). [0037] Once the cylinder (10) and the loading trolley (11) are mounted on the lifting platform (1), with the arm (70) closed, the extendable working device (40) is operated, which in the preferred configuration it corresponds to a double-acting hydraulic cylinder, which works through the working fluid provided by the drive unit (50), through the communication lines (41, 42), as seen in Figure 6B. Energization of the drive unit (50) occurs through an external battery or preferably using the battery of the vehicle where the platform (1) is arranged, by means of an energization cable (51). The functions of the extendable work device (40) can be controlled through the keypad or remote control (80), to raise or lower the loading surface (60) from the vehicle to the work surface (13). Finally, in the event that a lowering maneuver is carried out on the loading surface (60), the operator releases the arm (70) and proceeds to unload the cylinder (10) together with the loading trolley (11). In another embodiment of the present invention, the axis rotation is carried out automatically, using the drive unit (50) or the vehicle's engine as the energy source.
