Description

SISTEMA Y PROCEDIMIENTO PARA LA MANIPULACIÓN DE CONTENEDORES SYSTEM AND PROCEDURE FOR THE HANDLING OF CONTAINERS
DESCRIPCIÓN DESCRIPTION
La presente invención se refiere a un sistema y a un procedimiento para la manipulación de contenedores, en particular, para la manipulación de contenedores en alta mar, por ejemplo, en plataformas autónomas. The present invention relates to a system and a method for container handling, in particular for container handling offshore, for example on autonomous platforms.
Antecedentes de la invención Background of the invention
En las plataformas marítimas, tal como las plataformas petrolíferas y las plataformas de gas, descargar y cargar contenedores desde buques de servicio resulta un procedimiento de gran riesgo para operarios y bienes. On offshore platforms, such as oil platforms and gas platforms, unloading and loading containers from service vessels is a high-risk procedure for operators and property.
En la actualidad, estas maniobras tienen riesgos intrínsecos para los operarios que intervienen en el momento de enganchar y desenganchar las cadenas de elevación. At present, these maneuvers have intrinsic risks for the operators who intervene at the moment of hooking and unhooking the lifting chains.
Los movimientos marítimos del buque, junto con la capacidad de manejo del operario de la grúa, generan inestabilidad e inseguridad por el movimiento relativo entre la plataforma y el buque en el posicionamiento de dichos contenedores. The maritime movements of the ship, together with the handling capacity of the crane operator, generate instability and insecurity due to the relative movement between the platform and the ship in the positioning of said containers.
Esto provoca, a menudo, golpes e impactos con otros contenedores o estructuras metálicas del buque de carga. This often causes blows and impacts with other containers or metallic structures of the cargo ship.
En estos sectores se está implantando el concepto para la seguridad de plataformas autónomas, que busca reducir al máximo la presencia humana para su operación, evitando los riesgos para la salud de los operarios. In these sectors, the concept for the safety of autonomous platforms is being implemented, which seeks to minimize human presence for its operation, avoiding risks to the health of operators.
Por ejemplo, para intentar solucionar estos problemas de seguridad se ha diseñado el dispositivo descrito en el documento WO 2020101501 A1, que es un dispositivo de conexión para conectar un elemento de elevación a un elemento de elevación suspendido de un cable. Este dispositivo de conexión comprende una superficie superior que tiene al menos una parte en ángulo para guiar el elemento de elevación hacia un área de recepción. También comprende una parte de recepción del elemento de elevación configurada para sujetar la eslinga, en el que la parte de recepción del elemento de elevación está configurada además para recibir el elemento de elevación desde el área de recepción y proporcionar una conexión entre el elemento de elevación y la eslinga cuando el elemento de elevación se coloca en la parte de recepción del elemento de elevación. For example, to try to solve these safety problems, the device described in document WO 2020101501 A1 has been designed, which is a connection device for connecting a lifting element to a lifting element suspended from a cable. This connecting device comprises a top surface having at least one angled part for guiding the lifting element towards a receiving area. It also comprises a hoist receiving part configured to hold the sling, wherein the hoist receiving part is further configured to receive the hoist from the receiving area and provide a connection between the hoist and the sling when the hoist is placed on the receiving part of the hoist.
Aunque este dispositivo de conexión resuelve los problemas de seguridad para las personas implicadas, ya que se puede accionar a distancia, su uso es complicado, ya que depende en gran medida de la pericia del operador, ya que requiere que el operador coloque con precisión el elemento de elevación que cuelga de la eslinga en el área de recepción, que es relativamente pequeña. Although this connection device solves the safety problems for the people involved, since it can be operated remotely, its use is complicated, since it depends to a great extent on the skill of the operator, since it requires the operator to accurately position the lifting element that hangs from the sling in the receiving area, which is relatively small.
Debe tenerse en cuenta que esta operación muchas veces se realiza en condiciones de mala mar, con lo cual el barco se puede mover de manera considerable en cualquier dirección, así como el elemento de elevación por efecto del viento. It must be taken into account that this operation is often carried out in rough sea conditions, with which the boat can move considerably in any direction, as well as the lifting element due to the effect of the wind.

Descripción de una realización preferida Description of a preferred embodiment
Tal como se muestra en las figuras 1 y 2, el sistema de manipulación de contenedores comprende un bastidor desplazable, indicado en general mediante el número de referencia 1 , que comprende unas ruedas omnidireccionales 2 para permitir su desplazamiento en cualquier dirección sobre una superficie horizontal, por ejemplo, sobre la cubierta 10 de un buque. As shown in figures 1 and 2, the container handling system comprises a movable frame, generally indicated by the reference number 1, which includes omnidirectional wheels 2 to allow movement in any direction on a horizontal surface, for example, on deck 10 of a ship.
El bastidor desplazable 1 también comprende un elemento de acoplamiento 3, formando preferentemente por un gancho 31, un imán 32 y un cuerpo 33. The movable frame 1 also comprises a coupling element 3, preferably made up of a hook 31, a magnet 32 and a body 33.
Además, el bastidor desplazable 1 también comprende un cabezal 4 para conectar el bastidor desplazable 1 con el extremo de una eslinga 5. Para ello, el cabezal 4 comprende un pasador 41, y también comprende unos resortes de torsión 42 para mantener el gancho 31 en posición horizontal. Este cabezal 4 puede ajustarse en altura en el bastidor desplazable 1, por ejemplo, mediante un tornillo sin fin. In addition, the slidable frame 1 also comprises a head 4 for connecting the slidable frame 1 with the end of a sling 5. For this, the head 4 comprises a pin 41, and also comprises torsion springs 42 to keep the hook 31 in place. horizontal position. This head 4 can be adjusted in height on the movable frame 1, for example, by means of an endless screw.
Para mantener una porción de la eslinga 5 en posición vertical, evitando interferencias con el movimiento del bastidor desplazable 1, este bastidor desplazable 1 comprende una pértiga 6, que es de un material elástico. In order to keep a portion of the sling 5 in a vertical position, avoiding interference with the movement of the movable frame 1, this movable frame 1 comprises a pole 6, which is made of an elastic material.
Para garantizar una autonomía suficiente, el bastidor desplazable 1 también comprende un conjunto de baterías recargables 7, y también la electrónica de control adecuada. To guarantee a sufficient autonomy, the movable frame 1 also comprises a set of rechargeable batteries 7, and also the control electronics adequate.
Debe indicarse que el sistema de manipulación de contenedores de acuerdo con la presente invención permanece siempre en una plataforma en alta mar, y es en dicha plataforma donde dispone de un lugar reservado exclusivamente para el sistema y dispone de un sistema de recarga de baterías de carga por inducción. It should be noted that the container handling system according to the present invention always remains on a platform offshore, and it is on said platform where it has a place reserved exclusively for the system and has a charging battery recharging system. inductively.
Cuando es necesario, la grúa de la plataforma engancha con su gancho el extremo de la eslinga 5. Haciendo esto, el sistema queda listo para operar, tal como se explica a continuación. When necessary, the platform crane hooks the end of the sling 5 with its hook. By doing this, the system is ready to operate, as explained below.
El procedimiento de manipulación de contenedores de acuerdo con la presente invención es el siguiente. The container handling procedure according to the present invention is as follows.
En primer lugar, se debe colocar el bastidor desplazable 1 sobre la cubierta 10 del buque donde están colocados los contenedores 11. First of all, the movable frame 1 must be placed on the deck 10 of the ship where the containers 11 are placed.
De esta manera, según sea la lógica de la maniobra de carga y descarga de los contenedores, la grúa de la plataforma levantará y desplazará el bastidor desplazable 1 hasta depositarlo sobre la cubierta 10. Durante este proceso, la totalidad de la eslinga 5 está extendida y une el gancho de la grúa de la plataforma con el bastidor desplazable 1. In this way, according to the logic of the container loading and unloading maneuver, the platform crane will lift and move the movable frame 1 until it is deposited on the deck 10. During this process, the entire sling 5 is extended and join the hook of the platform crane with the sliding frame 1.
El procedimiento prevé que el bastidor desplazable 1 quede sobre la cubierta 10, sobre sus ruedas 2 y orientado en cualquier dirección y sin importar la distancia que le separe del contenedor 11 objetivo que va a ser cargado, como se muestra en la figura 4. The procedure foresees that the movable frame 1 remains on the cover 10, on its wheels 2 and oriented in any direction and regardless of the distance that separates it from the target container 11 that is going to be loaded, as shown in figure 4.
En el momento en el que el bastidor desplazable 1 es depositado sobre la cubierta 10, la grúa debe descender el gancho, dejando libre un tramo considerable de eslinga 5. Esto hará que la eslinga 5 quede holgada, sin tensión (figura 5). At the moment in which the movable frame 1 is deposited on the deck 10, the crane must lower the hook, leaving a considerable section of sling 5 free. This will cause the sling 5 to remain loose, without tension (figure 5).
En este punto interviene la pértiga 6, que tal como se ha indicado anteriormente, hará que siempre esté en vertical el tramo comprendido entre el pasador 41 y una distancia, por ejemplo, de entre 1,5 metros y 2 metros. At this point the pole 6 intervenes, which, as previously indicated, will always make the section between the pin 41 and a distance, for example, between 1.5 meters and 2 meters.
Cuando la eslinga 5 está tensionada, la pértiga 6 no afectará en sus propiedades y funcionalidades. En cambio, cuando la eslinga 5 está sin tensión, la pértiga 6 mantiene un tramo de eslinga 5 en vertical, separando del suelo el tramo sobrante que la grúa cederá para que el bastidor 1 pueda desplazarse libremente sobre la cubierta 10. When sling 5 is under tension, pole 6 will not affect its properties and functionality. On the other hand, when sling 5 is without tension, pole 6 maintains a section of sling 5 vertically, separating from the ground the excess section that the crane will yield so that frame 1 can move freely on deck 10.
Con la ayuda de la pértiga 6 se quiere conseguir que dicha eslinga 5 no toque el suelo, no interrumpiendo la maniobra de acercamiento al contenedor que el bastidor 1 se dispone a empezar. With the help of the pole 6, it is desired to ensure that said sling 5 does not touch the ground, not interrupting the approach maneuver to the container that the frame 1 is preparing to begin.
Como se muestra en la figura 6, el bastidor 1 puede desplazarse sobre la cubierta 10 en una superficie delimitada a una circunferencia de radio igual al tramo de la eslinga 5 holgado y con centro en el gancho de la grúa. La posición relativa de esta superficie de trabajo cambiará dependiendo de la posición vertical del gancho sobre la cubierta 10. Por lo tanto, el operador de la grúa deberá acompañar el movimiento del bastidor 1 para permitirle cubrir la totalidad de la superficie de la cubierta. As shown in figure 6, the frame 1 can move on the cover 10 on a surface delimited by a circumference of radius equal to the length of the sling 5 loose and centered on the crane hook. The relative position of this work surface will change depending on the vertical position of the hook on the roof 10. Therefore, the crane operator will have to accompany the movement of the frame 1 to allow it to cover the entire surface of the roof.
Además, la holgura de la eslinga 5 permite absorber los movimientos relativos entre la plataforma y el buque como consecuencia del oleaje, que es una de las condicionantes más restrictivas en este entorno de trabajo. In addition, the slack in the sling 5 makes it possible to absorb the relative movements between the platform and the ship as a result of waves, which is one of the most restrictive conditions in this work environment.
Dicho oleaje hace prácticamente imposible automatizar un sistema de enganche aéreo, es decir, colgado del gancho y en el aire. Esta imposibilidad recae en el hecho que la referencia de la grúa y la referencia del contenedor se mueven entre sí. Said waves make it practically impossible to automate an aerial hooking system, that is, hanging from the hook and in the air. This impossibility lies in the fact that the reference of the crane and the reference of the container move relative to each other.
Una vez se ha colocado el bastidor 1 junto al contenedor 11 que se desea cargar, se acopla el gancho 31 del elemento de acoplamiento 3 a una anilla de elevación 12 del contenedor 11. Once the frame 1 has been placed next to the container 11 to be loaded, the hook 31 of the coupling element 3 is coupled to a lifting eye 12 of the container 11.
Este acoplamiento se ve facilitado por el uso del imán 32, que acerca automáticamente la anilla de elevación 12 a su posición de acoplamiento. Una vez acoplado, a través de la eslinga 5 y la grúa, se puede elevar el contenedor y depositarlo sobre la plataforma. This engagement is facilitated by the use of the magnet 32, which automatically brings the lifting eye 12 closer to its engagement position. Once coupled, through the sling 5 and the crane, the container can be raised and deposited on the platform.
A pesar de que se ha hecho referencia a una realización concreta de la invención, es evidente para un experto en la materia que el sistema y el procedimiento descritos son susceptibles de numerosas variaciones y modificaciones, y que todos los detalles mencionados pueden ser sustituidos por otros técnicamente equivalentes, sin apartarse del ámbito de protección definido por las reivindicaciones adjuntas. Despite the fact that reference has been made to a specific embodiment of the invention, it is clear to a person skilled in the art that the described system and procedure are susceptible to numerous variations and modifications, and that all the mentioned details can be replaced by others. technically equivalent, without departing from the scope of protection defined by the attached claims.
