Description

Embarcation modulaire pour le transport des grumes par voie d'eau.Modular boat for transporting logs by water.
Domaine technique de l'invention.Technical Field of the Invention
L'invention est du domaine du transport des grumes par voie d'eau, tel que par voie fluviale, par voie maritime ou analogue. Elle a pour objet une embarcation organisée en radeau, destinée à être chargée de grumes pour leur transport par voie d'eau.The invention is in the field of transport of logs by water, such as by river, by sea or the like. It relates to a boat organized raft, intended to be loaded with logs for their transport by water.
Etat de la technique.State of the art
Pour le transport des grumes par voie d'eau, tel que par voie fluviale ou par voie maritime, il est couramment utilisé des rames tractées pour les bois flottants. Pour les bois non flottants, leur transport est réalisé par des chalands ou par des plates tractées, depuis le chantier forestier jusqu'au chargement des grumes sur un grumier, après triage des grumes et leur entreposage au port à bois.For the transport of logs by water, such as by river or by sea, towed oars for floating wood are commonly used. For non-floating timber, it is transported by barges or towed platforms from the forest yard to the loading of logs on a logging truck after sorting the logs and storing them at the timber port.
Les différents opérateurs chargés de manipuler les bois non flottants rencontrent des difficultés avec ce mode de chargement, et la manipulation et le transport des bois non flottants restent délicats. Par exemple, les forestiers disposent de plates qui présentent des surfaces et des tirants d'eau trop importants pour naviguer sur certains cours d'eau de faible profondeur et/ou de faible étendue. Les plates de dimensions réduites s'avèrent trop petites pour un chargement conséquent en grumes. Par exemple encore, une telle difficulté d'acheminement des grumes vers les ports à bois induit des problèmes de gestion des grumes pour les responsables des ports à bois, tels que des problèmes de planning et de disponibilité de matériel.The different operators in charge of handling non-floating woods encounter difficulties with this method of loading, and the handling and transport of non-floating woods remains delicate. For example, foresters have platforms with surfaces and drafts that are too large to navigate certain shallow and / or shallow streams. Smaller plates are too small for heavy log loading. For example, such a difficulty of routing logs to log harbors induces log management problems for log harbor managers, such as scheduling and material availability issues.
En outre, l'investissement nécessaire à l'achat de plates pour le transport des grumes, et les travaux de carénage et de réparation de ces plates, impliquent des surcoûts de production pour la filière bois. De surcroît, les délais d'obtention de telles plates sont longs en raison des surcharges de travail des chantiers navals. Objet de l'invention.In addition, the investment needed to purchase logs for the transport of logs, and the repair work and repair of these plates, involve additional production costs for the timber industry. In addition, the deadlines for obtaining such plates are long because of the workloads of the shipyards. Object of the invention
Le but de la présente invention est de proposer un matériel de navigation pour le transport des grumes, qui soit simple à réaliser et qui permette le transport des grumes de bois non flottant en eaux peu profondes. Il est plus particulièrement visé par la présente invention de proposer une embarcation qui soit peu onéreuse à réaliser, et dont la structure simplifie le travail des opérateurs aux différentes étapes de transport des grumes, depuis le chantier forestier vers le port à bois. Il est aussi visé par la présente invention de proposer une telle embarcation dont l'entretien et la maintenance soient simples et facilement réalisables. Il est aussi visé par la présente invention de proposer une telle embarcation dont la structure permette de maintenir aisément disponible l'embarcation, voire de la rendre adaptable à un besoin particulier correspondant à un volume donné de grumes à transporter.The purpose of the present invention is to provide a log shipping equipment, which is simple to perform and allows the transport of logs of non-floating wood in shallow water. It is more particularly the object of the present invention to provide a boat that is inexpensive to produce, and whose structure simplifies the work of operators at different stages of transport of logs, from the forest yard to the timber port. It is also the object of the present invention to provide such a boat whose maintenance and maintenance are simple and easily achievable. It is also the object of the present invention to provide such a boat whose structure makes it possible to keep the boat readily available, or even to make it adaptable to a particular need corresponding to a given volume of logs to be transported.
L'embarcation de la présente invention est destinée au transport de grumes par voie d'eau. Cette embarcation est principalement caractérisée en ce qu'elle est composée d'une pluralité de caissons flottants successivement reliés les uns aux autres par des moyens de liaison pour former conjointement un radeau porteur des grumes.The boat of the present invention is intended for the transport of logs by water. This boat is mainly characterized in that it is composed of a plurality of floating boxes successively connected to each other by connecting means to jointly form a raft carrying logs.
Ces dispositions sont telles que l'embarcation est composée d'un nombre N de caissons successivement reliés les uns aux autres, le nombre N de caissons étant choisi en fonction des besoins extemporanés selon le nombre de grumes à transporter. Les grumes étant immergées en partie, les caissons ne confèrent à l'embarcation que le complément de flottabilité nécessaire. On notera que ces dispositions divergent des habitudes prises dans le domaine du transport des grumes non flottantes, les grumes étant habituellement chargées sur des plates ou analogues dont la flottabilité est déterminée selon le poids global des grumes à transporter. II en ressort que l'embarcation de la présente invention est susceptible de naviguer en eaux peu profondes. En outre, la structure de l'embarcation permet d'adapter le nombre de caissons nécessaires pour un besoin donné. De plus, grâce à son caractère modulaire, l'embarcation permet d'adapter sa dimension à une puissance donnée d'un remorqueur. Par ailleurs, la formation de l'embarcation à partir de caissons successivement assemblés les uns aux autres offre une facilité d'emploi de l'embarcation, et un investissement réduit au regard des embarcations existantes de l'art antérieur, cet investissement étant de surcroît susceptible d'être progressif par l'acquisition étalée dans le temps d'un nombre N de caissons. En outre, la simplicité de structure de l'embarcation rend son carénage, son entretien et sa maintenance aisés. En outre, à partir d'une réserve de caissons disponibles, l'embarcation est susceptible d'être opérationnelle en permanence.These provisions are such that the boat is composed of a number N of boxes successively connected to each other, the number N of boxes being chosen according to extemporaneous needs according to the number of logs to be transported. The logs being partially immersed, the boxes only give the boat the additional buoyancy necessary. It will be noted that these provisions diverge from the habits of non-floating logs, the logs being usually loaded on plates or the like whose buoyancy is determined according to the overall weight of the logs to be transported. It follows that the boat of the present invention is likely to navigate in shallow waters. In addition, the structure of the boat makes it possible to adapt the number of boxes necessary for a given need. In addition, thanks to its modular nature, the boat allows to adapt its size to a given power of a tugboat. Moreover, the formation of the boat from caissons successively assembled to each other offers ease of use of the boat, and a reduced investment compared to the existing craft of the prior art, this investment being moreover likely to be progressive by the acquisition spread over time of a number N of boxes. In addition, the simplicity of structure of the boat makes it easy to refit, maintain and maintain. In addition, from a reserve of available boxes, the boat is likely to be operational permanently.
Les moyens de liaison entre deux caissons voisins sont plus particulièrement constitués par au moins un anneau ou analogue, et un organe d'ancrage de cet anneau sur chaque extrémité de caisson. Ce mode de liaison favorise les manipulations de chargement. Selon une autre variante de réalisation des dits moyens de liaison, ceux-ci sont constitués par un filin, les caissons étant équipés d'organes d'ancrage des extrémités du filin. On notera que l'utilisation d'un filin confère aux moyens de liaison entre deux caissons voisins une souplesse de navigation en courbe de la voie d'eau. En outre, l'utilisation de tels filins permet de faire varier l'espace entre deux caissons voisins selon le diamètre de la grume portée par ces caissons.The connecting means between two adjacent boxes are more particularly constituted by at least one ring or the like, and an anchor member of this ring on each end box. This connection mode favors loading manipulations. According to another embodiment of said connecting means, these are constituted by a rope, the boxes being equipped with anchoring members of the ends of the rope. It should be noted that the use of a rope gives the connecting means between two adjacent caissons a flexibility of navigation curve of the waterway. In addition, the use of such ropes makes it possible to vary the space between two neighboring caissons according to the diameter of the log carried by these boxes.
Les moyens de liaison reliant deux à deux les caissons sont susceptibles d'être formés par un anneau unique pour deux ancrages. Dans le cas d'une utilisation de filins reliant deux à deux les caissons, ceux-ci sont notamment formés par des chaînes. L'utilisation de chaînes permet aisément de relier deux à deux les caissons en exploitant les anneaux des chaînes pour leur fixation, et en exploitant le pas de la chaîne déterminé par la distance séparant deux anneaux voisins pour régler l'espace séparant deux caissons voisins tel que visé plus haut. Les organes d'ancrage sont par exemple constitués par des crochets de réception d'un maillon des chaînes.The connecting means connecting two by two the boxes are likely to be formed by a single ring for two anchors. In the case of a use of cables connecting the two boxes in pairs, they are formed in particular by chains. The use of chains makes it easy to connect the boxes in pairs by exploiting the rings of the chains for their attachment, and by exploiting the pitch of the chain determined by the distance separating two neighboring rings to adjust the space separating two adjacent boxes such as than referred to above. Organs anchoring are for example constituted by hooks for receiving a chain link.
Le profil des caissons est de conformation polygonale, pour former des facettes de soutien des grumes de l'un à l'autre de deux caissons voisins.The profile of the boxes is of polygonal conformation, to form facets supporting logs from one to the other of two neighboring boxes.
Selon une forme préférée de réalisation, le profil des caissons est de forme triangulaire.According to a preferred embodiment, the profile of the boxes is of triangular shape.
A titre indicatif, les dimensions de chacun des caissons sont pour leur base de l'ordre de 1,80 m, pour leur hauteur de l'ordre de 1 ,25 m et pour leur longueur de l'ordre de 4 m. On comprendra cependant que ces dimensions citées pour exemple peuvent être adaptées selon les besoins.As an indication, the dimensions of each of the caissons are for their base of the order of 1.80 m, for their height of the order of 1, 25 m and for their length of the order of 4 m. It will be understood, however, that these dimensions cited for example can be adapted as needed.
De préférence, les faces portantes des caissons sont munies de crampons d'agrippage des grumes. La présence des crampons sur les faces de soutien des caissons offre un maintien efficace des grumes. Par ailleurs, la présence des crampons permet de ménager un espace entre les grumes et les faces des caissons, cet espace étant susceptible d'être mis à profit pour le passage d'élingues destinées à la manutention des grumes, pour leur embarquement et pour leur débarquement notamment.Preferably, the load-bearing faces of the caissons are provided with crampons for gripping the logs. The presence of the crampons on the support surfaces of the caissons provides effective maintenance of the logs. Moreover, the presence of the crampons makes it possible to provide a space between the logs and the faces of the boxes, this space being likely to be put to good use for the passage of slings intended for the handling of the logs, for their loading and for their landing in particular.
Pour des raisons de sécurité, il est préféré de pourvoir l'embarcation d'au moins une élingue ou analogue, qui relie successivement les caissons les uns aux autres. Les caissons comporte un organe de passage de l'élingue, par exemple formé d'un anneau ménagé au sommet des caissons. L'élingue est notamment fixée à ses extrémités aux caissons d'extrémité de l'embarcation. De préférence, l'élingue circule en outre dans des anneaux de crochet enfoncés dans les grumes, en circulant successivement de l'une à l'autre de ces dernières. Les caissons sont préférentiellement en acier. On notera cependant que ce matériau constitutif des caissons n'est que préféré, et que ce matériau pourrait être un matériau différent sans déroger aux règles de l'invention.For safety reasons, it is preferred to provide the boat with at least one sling or the like, which successively connects the boxes to each other. The boxes comprises a sling passing member, for example formed of a ring formed at the top of the boxes. The sling is in particular fixed at its ends to the end boxes of the boat. Preferably, the sling is further circulated in hook rings driven into the logs, circulating successively from one to the other of the latter. The boxes are preferably made of steel. It should be noted, however, that this material constituting the boxes is only preferred, and that this material could be a different material without departing from the rules of the invention.
L'invention propose aussi un procédé d'embarquement de grumes sur une embarcation précédemment visée. Ce procédé consiste, à partir d'un nombre N de caissons à utiliser pour former l'embarcation, à relier deux caissons entre eux et à les placer en immersion. Puis, les caissons sont chargés en une grume reposant sur deux faces en regard des caissons. Un nouveau caisson est ensuite relié aux caissons précédents, et une nouvelle grume est chargée. Ces opérations sont ensuite répétées jusqu'à formation globale de l'embarcation chargée de grumes. L'ensemble N de caissons étant reliés deux à deux, le procédé comprend ensuite l'étape consistant à fixer sur le premier caisson une élingue et à faire circuler cette élingue de caissons en caissons et de grumes en grumes à travers les organes de passage de l'élingue équipant les caissons et les grumes, jusqu'au caisson terminal sur lequel l'élingue est fixée.The invention also provides a method of loading logs on a previously referred boat. This method consists, from a number N of boxes to be used to form the boat, to connect two boxes between them and to place them in immersion. Then, the caissons are loaded into a log resting on two faces opposite the caissons. A new box is then connected to the previous boxes, and a new log is loaded. These operations are then repeated until the overall formation of the boat loaded with logs. The set N of boxes being connected in pairs, the method then comprises the step of securing on the first box a sling and to circulate this sling box caissons and logs in logs through the passage bodies. the sling equipping the caissons and the logs, up to the terminal box on which the sling is fixed.
Lorsque l'embarcation arrive au port à bois, elle est accostée au quai. L'élingue est retirée et une grue procède au déchargement de l'embarcation, en passant une élingue du portique de déchargement autour de chaque extrémité de grume. On notera que le passage de cette élingue est facilité par l'espace ménagé entre les grumes et les faces des caissons, en raison de la présence des crampons.When the boat arrives at the timber port, she is docked at the dock. The sling is removed and a crane unloads the boat, passing a sling of the unloading gantry around each end of the log. Note that the passage of this sling is facilitated by the space between the logs and the faces of the boxes, because of the presence of the crampons.
Sur les caissons assemblés pour le transport des grumes, on peut ajouter des caissons semblables renversés et glissés entre les premiers caissons, de telle sorte qu'une surface plane de transport soit ménagée. Une 'telle surface plane est susceptible d'être utilisée pour le transport de divers matériels lorsque l'embarcation est ramenée à vide vers le chantier forestier. A titre d'exemple, pour cinq caissons positionnés pour les grumes, on ajoute quatre caissons renversés, ce qui procure une surface disponible plane de l'ordre de 4 m par 7,2 m, pour une charge maximale de l'ordre de 27 tonnes. Plus particulièrement, l'embarcation est susceptible de comporter avantageusement un premier groupe de caissons porteurs d'un deuxième groupe de caissons renversés par rapport à l'orientation des précédents, pour ménager une surface plane de transport de matériel lors du retour à vide de l'embarcation vers le chantier forestier.On caissons assembled for the transport of logs, it is possible to add similar boxes reversed and slid between the first boxes, so that a flat surface transport is arranged. Such a flat surface is likely to be used for the transport of various materials when the boat is brought empty to the forest yard. For example, for five caissons positioned for the logs, four inverted caissons are added, which provides a flat available surface of the order of 4 m by 7.2 m, for a maximum load of the order of 27. tons. More particularly, the boat is likely to advantageously comprise a first group of caissons carrying a second group of caissons overturned with respect to the orientation of the previous, to provide a planar surface for transporting equipment during the empty return of the boat to the forest yard.
Description des figures.Description of the figures.
La présente invention sera mieux comprise, et des détails en relevant apparaîtront, à la description qui va en être faite en relation avec les figures de la planche annexée, dans laquelle :The present invention will be better understood, and details will arise from the description that will be made in connection with the figures of the attached sheet, wherein:
La fιg.1 est une vue schématique d'une embarcation selon un exemple de réalisation de la présente invention.The fιg.1 is a schematic view of a boat according to an exemplary embodiment of the present invention.
La fig.2 est un détail de l'embarcation représentée sur la fig.1, illustrant la juxtaposition de deux caissons la composant.Fig.2 is a detail of the boat shown in Fig.1, illustrating the juxtaposition of two boxes component.
Sur la fig.1 , une embarcation pour le transport de grumes 1 est composée d'une pluralité de caissons 2 en acier reliés deux à deux en adjacence, par l'intermédiaire de chacun de leur bout. Ces caissons 2 ont une conformation prismatique, pour porter deux à deux une grume 1 logée entre deux faces voisines de deux caissons 2 adjacents.In Fig.1, a boat for the transport of logs 1 is composed of a plurality of steel boxes 2 connected in pairs adjacent, through each of their end. These caissons 2 have a prismatic conformation, to bring two by two a log 1 housed between two adjacent faces of two adjacent caissons 2.
En se reportant par ailleurs sur la fig.2, les caissons 2 sont reliés deux à deux par une chaîne 3. On comprendra que chacun des bouts des caissons est équipé d'une telle chaîne, ou moyen de liaison analogue, tel qu'un anneau en prise sur des organes d'ancrage que comportent les caissons. Cette chaîne 3 est en prise sur les caissons 2 par l'intermédiaire de ses maillons, qui sont enfilés sur des crochets 4 que comportent les caissons 2 au voisinage de leurs extrémités latérales. A partir du choix des maillons utilisés de la chaîne 3 pour sa fixation aux caissons 2, il est possible de régler la distance séparant deux caissons 2 voisins en fonction du diamètre de la grume 1 à transporter. Les faces des caissons 2 porteuses de la grume 1 sont dotées de crampons 5. Sur l'exemple de réalisation illustré, les crampons 5 sont alignés suivant la largeur de la face correspondante des caissons 2. On comprendra cependant que cette disposition des crampons 5 n'est que préférée, et est susceptible de varier sans déroger aux règles de l'invention qui ont été énoncées. Ces crampons 5 permettent non seulement de maintenir fermement la grume 1 sur l'embarcation, mais aussi permettent de ménager entre la grume 1 et les faces porteuses des caissons 2 un passage pour des élingues utilisées pour le chargement et le déchargement des grumes 1.Referring also to FIG. 2, the boxes 2 are connected in pairs by a chain 3. It will be understood that each end of the boxes is equipped with such a chain, or similar connecting means, such as a ring engaged on anchoring members that comprise the boxes. This chain 3 is engaged on the caissons 2 by means of its links, which are threaded onto hooks 4 that comprise the caissons 2 in the vicinity of their lateral ends. From the choice of the links used of the chain 3 for its attachment to the caissons 2, it is possible to adjust the distance separating two neighboring caissons 2 depending on the diameter of the log 1 to be transported. The faces of the caissons 2 carrying the log 1 are provided with crampons 5. In the exemplary embodiment illustrated, the crampons 5 are aligned along the width of the corresponding face of the caissons 2. However, it will be understood that this arrangement of the crampons 5 is preferred, and is capable of variation without departing from the rules of the invention that have been set forth. These crampons 5 not only allow to firmly hold the log 1 on the boat, but also allow to arrange between the log 1 and the carrying faces of the boxes 2 a passage for slings used for loading and unloading logs 1.
Pour sécuriser la tenue de l'embarcation, une élingue 6 relie l'ensemble des caissons 2 et les grumes 1 les uns aux autres. Cette élingue 6 circule à l'intérieur d'anneaux 7 équipant chacun des caissons 2, et à l'intérieur d'anneaux T ancrés dans les grumes 1. L'élingue 6 est ensuite fixée à ses extrémités aux caissons 2 d'extrémité de l'embarcation. Selon l'exemple de réalisation illustrée cette élingue 6 est unique, mais qu'il doit être compris que plusieurs élingues 6 sont susceptibles d'équiper l'embarcation de l'invention.To secure the holding of the boat, a sling 6 connects all the caissons 2 and the logs 1 to each other.
