La longitud de las cadenas 33 y 38 se calcula para proporcionar las condiciones de operación descritas en lo sucesivo.The length of chains 33 and 38 is calculated to provide the operating conditions described in successive.

El dispositivo está provisto de medios de accionamiento que actúan entre la parte inferior de la fosa 2 y la base 26 de la estructura 25; dichos medios consisten en el pantógrafo 43, que está motorizado de manera adecuada y es apropiado para producir el movimiento de traslación vertical de dicha estructura 25 entre la posición límite inferior, mostrada en la Figura 8, en la que la tapa 27 está en la condición de distancia mínima desde la base 26, al nivel del pavimento 3 que circunda la fosa, y la posición límite superior, mostrada en la Figura 10, en la que la base 26 se encuentra a dicho nivel del pavimento.The device is provided with means of drive acting between the bottom of the pit 2 and the base 26 of structure 25; said means consist of pantograph 43, which is properly motorized and is appropriate to produce the vertical translation movement of said structure 25 between the lower limit position, shown in the Figure 8, in which the cover 27 is in the distance condition minimum from base 26, at the level of pavement 3 surrounding the pit, and the upper limit position, shown in Figure 10, in the that the base 26 is at said level of the pavement.

La operación de la invención se describe ahora empezando desde la situación mostrada en la Figura 8, que es la situación de uso normal, en la que los usuarios introducen gradualmente las bolsas de residuos en los pilares 28a y 28b y dichas bolsas caen dentro del contenedor 5, que se acomoda en la porción de espacio delimitada por la base 26 y la tapa 27 en su mínima distancia mutua.The operation of the invention is now described. starting from the situation shown in Figure 8, which is the normal use situation, in which users enter gradually the waste bags on pillars 28a and 28b and said bags fall into the container 5, which is accommodated in the portion of space bounded by base 26 and cover 27 in its minimum mutual distance

Cuando es necesario vaciar el contenedor 5, se acciona el pantógrafo 43, lo que causa la elevación de la estructura 25, y se desplazan hacia arriba las cadenas 33 y 38, junto con las cadenas relacionadas con las columnas 31 y 32, que permanecen parcialmente sobre la parte inferior de la fosa 2.When it is necessary to empty container 5, it pantograph 43 is activated, which causes the structure to rise 25, and chains 33 and 38 move up, along with the strings related to columns 31 and 32, which remain partially over the bottom of the pit 2.

Se alcanza de esta manera la situación mostrada en la Figura 9, en la que dichas cadenas se han extendido completamente pero no están aún tensadas, y en esta situación no ha ocurrido nada para que cambie la distancia mutua entre la base 26 y la tapa 27, que están por lo tanto todavía en la mínima distancia mutua, puesto que se encuentran en la situación de la Figura 8.The situation shown is reached in this way in Figure 9, in which said chains have been extended completely but they are not yet strained, and in this situation it has not nothing happened to change the mutual distance between base 26 and the cover 27, which are therefore still in the minimum distance mutual, since they are in the situation of Figure 8.

A medida que continúa la ascensión de la estructura 25, las cadenas, como 33, 38, se deslizan sobre las poleas correspondientes, como 35 y 40, lo que causa la ascensión de las secciones de las columnas telescópicas que están rígidamente unidas a la tapa 27, como 29b y 30b para las columnas 29 y 30, con respecto a las secciones como 29a y 30a que están rígidamente unidas a la base 26, y la longitud de dichas cadenas se calcula de manera que cuando la estructura 25 alcanza la posición mostrada en la Figura 10, en la que la base 26 está al nivel del pavimento 3 que circunda la fosa, la tapa 27 se ha elevado con respecto a la base 26 en una cantidad considerada ideal con el fin de vaciar completamente los pilares 28a, 28b dentro del contenedor 5 y permitir la sencilla extracción de dicho contenedor.As the ascension of the structure 25, the chains, like 33, 38, slide over the corresponding pulleys, such as 35 and 40, which causes the rise of the sections of the telescopic columns that are rigidly attached to cover 27, such as 29b and 30b for columns 29 and 30, with regarding sections like 29a and 30a that are rigidly joined to base 26, and the length of said chains is calculated so that when structure 25 reaches the position shown in the Figure 10, in which the base 26 is at the level of the pavement 3 which circle the pit, the cover 27 has been raised with respect to the base 26 in an amount considered ideal in order to completely empty the pillars 28a, 28b inside the container 5 and allow the simple removal of said container.

La invención descrita es susceptible de otras numerosas modificaciones y variaciones, todas ellas incluidas dentro del alcance del mismo concepto inventivo; de esta manera, por ejemplo, los elementos a modo de cable pueden estar constituidos por cables y pueden estar guiados a lo largo de guías que sean por ejemplo apropiadas para concentrar los puntos de acoplamiento al fondo de la fosa.The described invention is susceptible to others. numerous modifications and variations, all included within the scope of the same inventive concept; this way, for For example, the cable-like elements may consist of cables and can be guided along guides that are by appropriate example to concentrate the coupling points to the bottom of the pit.
