La grúa para manipulación de cargas que se preconiza, ha sido concebida para resolver la problemática anteriormente expuesta, basándose en la estructura de una grúa convencional pero con la novedad o especial particularidad de que bajo el carro desplazable sobre la pluma de la grúa, carro sobre el que va a quedar siempre suspendida de la carga, va situada una cámara de vídeo enfocada verticalmente hacia el suelo, llevando a cabo una grabación permanente tanto de la carga como del área circundante a la misma, perteneciendo a dicha cámara un circuito cerrado de televisión en el que la pantalla de visualización puede estar situada en un lugar adecuado, por ejemplo, en el propio mando a distancia o en cualquier lugar de la obra que se desee.The crane for handling loads advocates, has been designed to solve the problem previously exposed, based on the structure of a crane conventional but with the novelty or special particularity that under the movable car on the crane boom, car on the that will always be suspended from the load, a video camera focused vertically towards the ground, leading to make a permanent recording of both the load and the area surrounding it, a circuit belonging to said chamber closed television in which the display screen can be located in a suitable place, for example, in the command itself remotely or anywhere in the desired work.
De esta manera, la persona que maneja la grúa con el mando a distancia, podrá conocer en todo momento la situación de la carga y si se encuentra próxima a algún obstáculo que desde su punto de operaciones no pudiera ver, lo que permite situar a dicha persona en cualquier lugar de la obra y realizar las operaciones con total fiabilidad y eficacia, ya que el campo de visión que le ofrece la pantalla de visualización del circuito cerrado de televisión conectado a la cámara de vídeo, le otorga el campo de visión total en el que se encuentra la carga y el área circundante de la misma.In this way, the person who drives the crane with the remote control, you can know at all times the situation of the load and if it is close to any obstacle that from its operations point could not see, which allows to place said person anywhere in the work and perform operations with total reliability and efficiency, since the field of vision that offers the closed circuit display screen of television connected to the camcorder, gives you the field of total vision in which the load is located and the surrounding area Of the same.
Para complementar la descripción que se está realizando y con objeto de ayudar a una mejor comprensión de las características del invento, de acuerdo con un ejemplo preferente de realización práctica del mismo, se acompaña como parte integrante de dicha descripción, un juego de dibujos en donde con carácter ilustrativo y no limitativo, se ha representado lo siguiente:To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:
Figura 1.- muestra una vista en alzado lateral de una grúa manipulando una carga e incorporando en el correspondiente carro de suspensión de dicha carga una cámara de vídeo enfocada verticalmente hacia abajo, concretamente a la carga y al área circundante de la misma.Figure 1.- shows a side elevation view of a crane handling a load and incorporating in the corresponding suspension carriage of said load a focused video camera vertically down, specifically to the load and the area surrounding of it.
Figura 2.- muestra un detalle de la disposición y orientación de la cámara de vídeo sobre el correspondiente carro de la grúa.Figure 2.- shows a detail of the arrangement and orientation of the video camera on the corresponding carriage Crane.
A la vista de las figuras reseñadas puede observarse la grúa de la invención, constituida como es convencional a partir de una columna (1) con su correspondiente pluma (2) que es giratoria respecto de su punto (3) de montaje sobre la columna vertical y estática (1), estando dicha pluma (2) de la grúa dotada del respectivo carro (4) desplazable a lo largo de tal pluma (2) y de cuyo carro (4) queda suspendida la correspondiente carga (5), todo ello como es convencional.In view of the figures outlined you can observe the crane of the invention, constituted as is conventional starting from a column (1) with its corresponding boom (2) that is rotatable with respect to its mounting point (3) on the vertical and static column (1), said pen (2) being of the crane equipped with the respective carriage (4) movable along such pen (2) and whose carriage (4) is suspended the corresponding load (5), all as conventional.
