Description

La présente invention est relative à un dispositif pour soulever une charge, et à un procédé pour mettre en oeuvre un tel dispositif.The present invention relates to a device for lifting a load, and to a method for implementing such a device.

Il est connu de soulever une charge par une grue. Par exemple, un transformateur électrique est une charge particulièrement lourde et mal aisée à manipuler. A cette fin, l'enveloppe du transformateur électrique comprend habituellement sur sa partie supérieure des anneaux de levage. Par exemple, le document JP9306746 décrit un procédé de levage d'un transformateur électrique utilisant deux grues pour soulever et incliner le transformateur, dans le but d'éviter les chocs du transformateur avec des moyens de transports lors de son expédition.It is known to lift a load by a crane. For example, an electrical transformer is a particularly heavy load and difficult to handle. For this purpose, the envelope of the electrical transformer usually comprises on its upper part lifting rings. For example, the document JP9306746 describes a method of lifting an electrical transformer using two cranes to lift and tilt the transformer, in order to avoid shock of the transformer with means of transport during its shipment.

Un tel moyen de levage par grue est impossible lorsque la charge est déjà installée dans une enceinte fermée d'un bâtiment, dans laquelle il y a peu d'espace autour et surtout au dessus de ladite charge.Such crane lifting means is impossible when the load is already installed in a closed chamber of a building, in which there is little space around and above above said load.

La présente invention a pour but de proposer un dispositif pour soulever une charge à l'intérieur d'une enceinte fermée, sans utilisation d'une grue.The present invention aims to provide a device for lifting a load inside a closed chamber without the use of a crane.

A cet effet, le dispositif pour soulever une charge, comprend :

  • une structure support comprenant au moins des montants verticaux destinés à prendre appui au sol,
  • une structure de suspension comprenant au moins une poutre comportant des moyens d'accrochage pour suspendre une partie supérieure de la charge, ladite structure de suspension étant mobile en déplacement au moins selon une direction verticale entre une position abaissée et une position relevée, et
  • au moins un vérin commandé pour provoquer le déplacement de ladite structure de suspension entre ladite position abaissée et ladite position relevée.
For this purpose, the device for lifting a load, comprises:
  • a support structure comprising at least vertical uprights intended to bear on the ground,
  • a suspension structure comprising at least one beam comprising hooking means for suspending an upper part of the load, said suspension structure being movable in displacement at least in a vertical direction between a lowered position and a raised position, and
  • at least one cylinder controlled to cause the displacement of said suspension structure between said lowered position and said raised position.

Grâce à ces dispositions, la charge peut être soulevée dans une enceinte fermée.Thanks to these arrangements, the load can be raised in a closed enclosure.

En outre, il est alors possible d'installer au moins un élément sous ladite charge. Par exemple, il est possible dans le cas d'un transformateur électrique à diélectrique liquide d'installer un bac de rétention de liquide sous ledit transformateur, pour se conformer à la réglementation actuelle.In addition, it is then possible to install at least one element under said load. For example, it is possible in the case of a liquid dielectric electrical transformer to install a liquid retention tank under said transformer, to comply with current regulations.

Dans divers modes de réalisation du dispositif selon l'invention, on peut éventuellement avoir recours en outre à l'une et/ou à l'autre des dispositions suivante :

  • lesdites structures support et de suspension sont assemblables et démontables sur place, autour de la charge ;
  • la structure support a au moins une dimension réglable ;
  • la charge est un transformateur électrique à diélectrique liquide ;
  • la structure support comprend :

Sur cette figure 1, les montants verticaux sont au nombre de quatre : un premier montant 11, un deuxième montant 12, un troisième montant 13 et un quatrième montant 14, ayant chacun respectivement une extrémité inférieure 11a, 12a, 13a, 14a prenant appui sur le sol et ayant chacun respectivement une extrémité supérieure 11b, 12b, 13b, 14b. Chaque montant s'étend dans une direction verticale depuis son extrémité inférieure vers son extrémité supérieure.On this figure 1 the vertical uprights are four in number: a first upright 11, a second upright 12, a third upright 13 and a fourth upright 14, each having respectively a lower end 11a, 12a, 13a, 14a resting on the floor and having each respectively an upper end 11b, 12b, 13b, 14b. Each post extends in a vertical direction from its lower end to its upper end.

Les quatre montants verticaux 11, 12, 13, 14 sont donc sensiblement parallèles entre eux.The four uprights 11, 12, 13, 14 are substantially parallel to each other.

Les quatre extrémités inférieures 11a, 12a, 13a, 14a de ces montants verticaux sont espacés au sol et forment sensiblement quatre coins d'un premier rectangle R1. Les quatre extrémités supérieures 11b, 12b, 13b, 14b de ces montants verticaux forment également sensiblement quatre coins d'un second rectangle sensiblement identique au premier rectangle à une première hauteur H1 par rapport au sol.The four lower ends 11a, 12a, 13a, 14a of these vertical uprights are spaced apart on the ground and form substantially four corners of a first rectangle R1. The four upper ends 11b, 12b, 13b, 14b of these vertical uprights also form substantially four corners of a second rectangle substantially identical to the first rectangle at a first height H1 relative to the ground.

La structure support 2 comprend en outre des traverses 21, 22, 23, 24 sensiblement horizontales. La première traverse 21 relie le premier montant 11 au deuxième montant 12. La deuxième traverse 22 relie le deuxième montant 12 au troisième montant 13. La troisième traverse 23 relie le troisième montant 13 au quatrième montant 14. La quatrième traverse 24 relie le quatrième montant 14 au premier montant 11. Ainsi tous les montants verticaux sont reliés deux à deux par au moins une traverse et l'ensemble des montants et des traverses forme une structure support 2 rigide.The support structure 2 further comprises crosspieces 21, 22, 23, 24 substantially horizontal. The first cross member 21 connects the first amount 11 to the second amount 12. The second cross member 22 connects the second amount 12 to the third amount 13. The third cross member 23 connects the third amount 13 to the fourth amount 14. The fourth cross member 24 connects the fourth amount 14 to the first amount 11. Thus all the uprights are connected two by two by at least one cross and all of the uprights and cross members form a rigid support structure 2.

Dans l'exemple de la figure 1, les première et troisième traverses 21, 23 sont situées à une première hauteur H1 par rapport au sol. Elles relient donc les extrémités supérieures des montants verticaux.In the example of the figure 1 the first and third cross members 21, 23 are located at a first height H1 with respect to the ground. They therefore connect the upper ends of the uprights.

Les deuxième et quatrième traverses 22, 24 sont situées à une deuxième hauteur H2 par rapport au sol, différente de la première hauteur H1, et dans cet exemple à une deuxième hauteur H2 inférieure à la première hauteur H1. La structure support 2 est ainsi encore plus rigide.The second and fourth cross members 22, 24 are located at a second height H2 relative to the ground, different from the first height H1, and in this example to a second height H2 less than the first height H1. The support structure 2 is thus even more rigid.

Chacun de ces montants et traverses est réalisé par assemblage de composants qui sont emboités les uns aux autres et fixés entre eux par des moyens de fixations, tels que des goupilles. Mais tout autre mode d'assemblage et de fixation peut être utilisé. La structure support 2 ainsi assemblée est constituée de composants de dimension réduite, facilement transportable par tout véhicule, et peut être facilement installée et montée directement autour de la charge dans une enceinte fermée, sans qu'il y ait besoin d'espace autour et au dessus de la charge.Each of these amounts and sleepers is made by assembling components that are nested to each other and fixed together by means of fasteners, such as pins. But any other method of assembly and fixation can be used. The support structure 2 thus assembled consists of components of reduced size, easily transportable by any vehicle, and can be easily installed and mounted directly around the load in a closed chamber, without the need for space around and at above the charge.

Chaque composant est lui-même réalisé par soudage de portions de profilés de section quelconque, et avantageusement de section carrée ou circulaire. Les composants sont ainsi peu onéreux à fabriquer.Each component is itself made by welding portions of sections of any section, and advantageously of square or circular section. The components are thus inexpensive to manufacture.

Une description plus détaillée des composants des traverses 21, 22, 23, 24 sera faite plus loin à l'aide de la figure 3.A more detailed description of the components of sleepers 21, 22, 23, 24 will be made later using the figure 3 .

La structure support 2 comprend également quatre guides 31, 32, 33, 34, ayant chacun la forme d'un profilé sensiblement vertical et destiné à guider le déplacement de la structure de suspension 3 par rapport à la structure support (2).The support structure 2 also comprises four guides 31, 32, 33, 34, each having the shape of a substantially vertical profile and intended to guide the displacement of the suspension structure 3 with respect to the support structure (2).

Des premier et deuxième guides 31, 32, sensiblement parallèles, prennent appui par leurs extrémités inférieures sur la deuxième traverse 22. Un premier palier 41 appartenant à la structure de suspension 3 est monté coulissant sur lesdits premier et deuxième guides 31, 32.First and second guides 31, 32, substantially parallel, supported by their lower ends on the second crosspiece 22. A first bearing 41 belonging to the suspension structure 3 is slidably mounted on said first and second guides 31, 32.

De manière similaire, des troisième et quatrième guides 33, 34, sensiblement parallèles, prennent appui par leurs extrémités inférieures sur la quatrième traverse 24. Un deuxième palier 42 appartenant à la structure de suspension 3 est monté coulissant sur lesdits troisième et quatrième guides 33, 34.Similarly, substantially parallel third and fourth guides 33, 34 are supported by their lower ends on the fourth crosspiece 24. A second bearing 42 belonging to the suspension structure 3 is slidably mounted on said third and fourth guides 33, 34.

Ainsi, la structure de suspension 3 de la figure 1 comprend au moins:

  • un premier palier 41 monté coulissant sur les premier et deuxième guides 31, 32, de la structure support 2,
  • un deuxième palier 42 monté coulissant sur les troisième et quatrième guides 33, 34, de la structure support 2,
  • une poutre 4 reliant entre eux les premier et deuxième paliers 41, 42.
  • deux moyens d'accrochages 5 fixés à ladite poutre 4.
Thus, the suspension structure 3 of the figure 1 includes at least:
  • a first bearing 41 slidably mounted on the first and second guides 31, 32, of the support structure 2,
  • a second bearing 42 slidably mounted on the third and fourth guides 33, 34, of the support structure 2,
  • a beam 4 interconnecting the first and second bearings 41, 42.
  • two hooking means 5 fixed to said beam 4.

Les premier et deuxième paliers 41, 42 sont formés par exemple par des profilés soudés et présentent une forme générale de H dont les deux branches verticales sont des profilée ouverts à leur extrémité adaptés pour venir autour et coulisser sur les guides correspondants.The first and second bearings 41, 42 are formed for example by welded sections and have a general shape of H whose two vertical branches are open at their end profiles adapted to come around and slide on the corresponding guides.

La poutre 4 est montée sur lesdits premier et deuxièmes paliers 41, 42, par emboitement dans une chape 43 (voir en figure 3) de chaque palier. Elle est ensuite fixée par une goupille (non représentée) traversant chaque chape 43.The beam 4 is mounted on said first and second bearings 41, 42, by interlocking in a yoke 43 (see FIG. figure 3 ) of each level. It is then fixed by a pin (not shown) passing through each yoke 43.

La chape 43 peut inversement être formée sous les extrémités de la poutre 4. La poutre 4 est alors montée sur lesdits premier et deuxième paliers 41, 42, par emboitement de la chape 43 sur chaque palier.The yoke 43 may be inversely formed under the ends of the beam 4. The beam 4 is then mounted on said first and second bearings 41, 42, by interlocking the yoke 43 on each bearing.

Les moyens d'accrochage 5 sont par exemple formés par une tige filetée en forme de U entourant la poutre 4 et fermée par une platine retenue sur ladite tige par des écrous. Ces moyens d'accrochage 5 forment ainsi chacun une boucle autour de la poutre 4, et destinée à être engagés dans des anneaux de levage 51 de la charge 50 (voir figure 2).The attachment means 5 are for example formed by a U-shaped threaded rod surrounding the beam 4 and closed by a plate retained on said rod by nuts. These attachment means 5 thus each form a loop around the beam 4, and intended to be engaged in lifting rings 51 of the load 50 (see FIG. figure 2 ).

La figure 2 représente d'une manière générale une charge 50. La charge 50 représentée est par exemple un transformateur électrique, notamment un transformateur électrique à diélectrique liquide. Pour plus de clarté de la description, cette charge 50 sera dénommé dans la suite « transformateur électrique ».The figure 2 is generally a load 50. The load 50 shown is for example an electrical transformer, including a liquid dielectric electrical transformer. For clarity of the description, this load 50 will be referred to in the following "electrical transformer".

Le transformateur électrique 50 comporte d'une manière générale une cuve 53 sensiblement parallélépipédique comportant sur ses quatre faces latérales des ailettes formant radiateur thermique. La cuve 53 est fermé en partie supérieure par un couvercle 55 étanche. Ainsi, les bobines électriques (non représentées) sont enfermées à l'intérieur de ladite cuve et immergées dans un liquide diélectrique. Des galets 52 sont montés sous la cuve 53. Le transformateur électrique 50 peut être déplacé sur le sol par roulement sur ces galets 52.The electrical transformer 50 generally comprises a substantially parallelepipedal vessel 53 having on its four lateral faces fins forming a heat radiator. The tank 53 is closed at the top by a cover 55 sealed. Thus, the electric coils (not shown) are enclosed inside said tank and immersed in a dielectric liquid. Rollers 52 are mounted under the tank 53. The electrical transformer 50 can be moved on the ground by rolling on these rollers 52.

Le couvercle 55 comprend des anneaux de levages 51, permettant de soulever ledit transformateur. La figure 2 comprend seulement deux anneaux de levage 51, un à chaque extrémité longitudinale du couvercle 55. Cette configuration est adaptée aux deux moyens d'accrochages 5 montés sur la poutre 4 du dispositif 1. Mais un homme du métier comprendra aisément comment modifier la structure de suspension 3 pour permettre le lever une charge disposant d'un nombre quelconque d'anneaux de levages 51.The cover 55 comprises lifting rings 51, for lifting said transformer. The figure 2 comprises only two lifting rings 51, one at each longitudinal end of the cover 55. This configuration is adapted to the two attachment means 5 mounted on the beam 4 of the device 1. But a person skilled in the art will easily understand how to modify the suspension structure 3 to lift a load having any number of lifting rings 51.

Le transformateur électrique 50 présente également des branchements électriques (bornes de connexion et câbles) de son primaire et secondaire pour son fonctionnement électrique.The electrical transformer 50 also has electrical connections (terminals and cables) of its primary and secondary for its electrical operation.

Le transformateur électrique 50 a en projection sur le sol un périmètre ou profil indiqué par la courbe P de la figure 2.The electrical transformer 50 has in projection on the ground a perimeter or profile indicated by the curve P of the figure 2 .

Le dispositif 1 de la figure 1 est donc monté en place autour de la charge, le transformateur électrique 50, de telle sorte que le premier rectangle RI cité ci-dessus entoure sensiblement ledit transformateur électrique.Device 1 of the figure 1 is thus mounted in place around the load, the electrical transformer 50, so that the first rectangle RI cited above substantially surrounds said electrical transformer.

Plus précisément, le profil P du transformateur électrique 50 peut soit être inclus dans le premier rectangle RI comme cela est représenté schématiquement en figure 2A, soit être partiellement inclus dans ce premier rectangle RI comme représenté schématiquement en figure 2B. Dans ce dernier cas, deux côtés du rectangle RI sont à l'extérieur du profil P et les deux autres côtés du rectangle R1 croisent le profil P, c'est-à-dire que les deux traverses correspondant à ces deux autres côtés sont à une hauteur bien supérieure à la hauteur du transformateur électrique, pour pouvoir le soulever sous lesdites traverses.More specifically, the profile P of the electrical transformer 50 can either be included in the first rectangle RI as shown schematically in FIG. Figure 2A , be partially included in this first rectangle RI as schematically represented in Figure 2B . In the latter case, two sides of the rectangle RI are outside the profile P and the other two sides of the rectangle R1 intersect the profile P, that is to say that the two crosspieces corresponding to these two other sides are at a height much greater than the height of the electrical transformer, to be able to lift under said sleepers.

La figure 3 détaille par un éclaté la construction de la structure support 2 et de la structure de suspension 3 du dispositif 1. Cette figure 3 ne présente pas tous les éléments pour plus de clarté, mais l'ensemble de la structure peut facilement être reconstitué par la symétrie générale du dispositif 1 facilement identifiable en figure 1.The figure 3 details by an exploded the construction of the support structure 2 and the suspension structure 3 of the device 1. This figure 3 does not present all the elements for clarity, but the whole structure can easily be reconstituted by the general symmetry of the device 1 easily identifiable in figure 1 .

Le premier montant 11 vertical est par exemple réalisé avec un simple profilé, ayant une longueur sensiblement égale à la première hauteur H1. Ce premier montants 11 est par exemple réalisé avec un profilé cylindrique ayant sensiblement à mi-hauteur, entre son extrémité inférieure 11a et son extrémité supérieure 11b des trous traversant 15 destinés à accueillir des goupilles destinées à servir de butée pour déterminer la position verticale des deuxième et quatrièmes traverses 22, 24, c'est-à-dire la deuxième hauteur H2.The first upright 11 is for example made with a simple profile, having a length substantially equal to the first height H1. This first upright 11 is for example made with a cylindrical section having substantially halfway between its lower end 11a and its upper end 11b through holes 15 for receiving pins intended to serve as a stop to determine the vertical position of the second and fourth cross members 22, 24, i.e. the second height H2.

Les deuxième 12, troisième 13 et quatrième 14 montants sont réalisés de manière identique au premier montant 11.The second 12, third 13 and fourth 14 amounts are made identically to the first amount 11.

La quatrième traverse 24 comprend trois composants :

  • un premier composant 24.1 en forme de T couché, ayant une branche verticale 24.1a et une branche horizontale 24.1b sensiblement à mi-hauteur de ladite branche verticale 24.1a,
  • un deuxième composant 24.2 en forme de T couché, ayant une branche verticale 24.2a et une branche horizontale 24.2b sensiblement à mi-hauteur de ladite branche verticale 24.2a, ledit deuxième composant 24.2 étant couché en direction opposée à celle du premier composant 24.1 de telle sorte que la branche horizontale 24.1b du premier composant et la branche horizontale 24.2b du deuxième composant soient alignées,
  • un troisième composant 24.3 en forme de PI inversé, ayant une branche horizontale 24.3a et deux branches verticales 24.3b, 24.3c, ladite branche horizontale 24.3a étant alignée avec les branches horizontales 24.1b, 24.2b des premier et deuxième composants, et lesdites branches verticales 24.3b, 24.3c étant dirigées vers le haut depuis la branche horizontale 24.3a dudit troisième composant 24.3.
The fourth crossbar 24 comprises three components:
  • a first coated T-shaped component 24.1 having a vertical leg 24.1a and a horizontal leg 24.1b substantially halfway up said vertical leg 24.1a,
  • a second coated T-shaped component 24.2, having a vertical leg 24.2a and a horizontal leg 24.2b substantially halfway up said vertical leg 24.2a, said second component 24.2 lying in a direction opposite to that of the first component 24.1 of such that the horizontal leg 24.1b of the first component and the horizontal leg 24.2b of the second component are aligned,
  • a third inverted PI shaped component 24.3, having a horizontal leg 24.3a and two vertical legs 24.3b, 24.3c, said horizontal leg 24.3a being aligned with the horizontal legs 24.1b, 24.2b of the first and second components, and said vertical branches 24.3b, 24.3c being directed upwardly from the horizontal leg 24.3a of said third component 24.3.

Les branches horizontales 24.1b, 24.2b, 24.3a des premier, deuxième et troisième composants sont adaptées pour s'emboiter avec faible jeu. Par exemple, elles sont chacune formée par un profilé rectangulaire creux, et les dimensions externes des branches horizontales 24.1b, 24.2b des premier et deuxième composants sont inférieures aux dimensions internes de la branche horizontale 24.3a du troisième composant, de telle sorte que les premier et deuxième composants 24.1, 24.2 soient enfilées dans le troisième composant 24.3.The horizontal branches 24.1b, 24.2b, 24.3a of the first, second and third components are adapted to fit with little clearance. For example, they are each formed by a hollow rectangular profile, and the external dimensions of the horizontal branches 24.1b , 24.2b of the first and second components are smaller than the internal dimensions of the horizontal leg 24.3a of the third component, so that the first and second components 24.1, 24.2 are threaded into the third component 24.3.

Dans une première variante représentée en figure 3A, les branches horizontales 24.1b, 24.2b des premiers et deuxièmes composants peuvent avoir des dimensions identiques et avoir des extrémités se faisant face et pouvant venir en butée dans le troisième composant 24.3.In a first variant represented in figure 3A , the horizontal branches 24.1b, 24.2b of the first and second components may have dimensions identical and having ends facing each other and able to abut in the third component 24.3.

Dans une deuxième variante représentée en figure 3B, les branches horizontales 24.1b, 24.2b des premier et deuxième composants peuvent avoir des dimensions adaptées pour être emboîtées l'une dans l'autre, l'ensemble des branches horizontales 24.1b, 24.2b étant emboîtées ou enfilées de même dans la branche horizontale 24.3a du troisième composant 24.3.In a second variant represented in figure 3B , the horizontal branches 24.1b, 24.2b of the first and second components may have dimensions adapted to be nested one inside the other, all of the horizontal branches 24.1b, 24.2b being nested or strung together in the branch horizontal 24.3a of the third component 24.3.

Grâce à ces trois composants, la largeur de la quatrième traverse 24 est réglable dans une plage de largeur prédéterminée.With these three components, the width of the fourth cross member 24 is adjustable within a predetermined width range.

Les branches verticales 24.1a, 24.2a des premier et deuxième composants sont formées avec un profilé creux, par exemple rectangulaire en figure 3, et sont adaptées pour être alignées et enfilées sur les premier et quatrième montants 11, 14, respectivement, jusqu'à une butée formée par une goupille insérée dans les trous traversant 15 desdits premier et quatrième montants 11, 14. De cette manière, la position verticale de la quatrième traverse 24 est réglée à la deuxième hauteur H2.The vertical branches 24.1a, 24.2a of the first and second components are formed with a hollow profile, for example rectangular in figure 3 and are adapted to be aligned and threaded on the first and fourth uprights 11, 14, respectively, to an abutment formed by a pin inserted into the through holes 15 of said first and fourth uprights 11, 14. In this manner, the vertical position of the fourth cross member 24 is set to the second height H2.

Les branches verticales 24.3c, 24.3b du troisième composant 24.3 sont adaptées pour accueillir les troisième et quatrième guides 33, 34 respectivement. Par exemple, elles sont chacune formée par un profilé creux dont les dimensions internes sont supérieures aux dimensions externes du profilé desdits troisième et quatrièmes guides 33, 34. Les troisième et quatrième guides 33, 34 sont ainsi emboités verticalement depuis le haut dans lesdites branches verticales 24.3b, 24.3c dudit troisième composant jusqu'à venir en butée contre la branche horizontale 24.3a dudit troisième composant 24.3.The vertical branches 24.3c, 24.3b of the third component 24.3 are adapted to accommodate the third and fourth guides 33, 34 respectively. For example, they are each formed by a hollow section whose internal dimensions are greater than the external dimensions of the profile of said third and fourth guides 33, 34. The third and fourth guides 33, 34 are thus fitted vertically from above in said vertical branches. 24.3b, 24.3c of said third component until it comes into abutment against the horizontal branch 24.3a of said third component 24.3.

La deuxième traverse 22 comprend trois autres composants similaires à ceux de la quatrième traverse. La deuxième traverse a ainsi une largeur réglable dans la même plage de largeur prédéterminée.The second cross member 22 comprises three other components similar to those of the fourth cross member. The second cross member thus has an adjustable width in the same predetermined width range.

La première traverse 21 comprend deux composants :

  • un premier composant 21.1 en forme de L couché, ayant une branche verticale 21.1a et une branche horizontale 21.1b, et
  • un second composant 21.2 en forme de L couché, ayant une branche verticale 21.2a et une branche horizontale 21.2b, ledit deuxième composant 21.2 étant couché en direction opposée à celle du premier composant de telle sorte que la branche horizontale 21.1b du premier composant et la branche horizontale 21.2b du second composant soient alignées et emboitées l'une dans l'autre.
The first cross member 21 comprises two components:
  • a first lying L-shaped component 21.1 having a vertical leg 21.1a and a horizontal leg 21.1b, and
  • a second coated L-shaped component 21.2 having a vertical leg 21.2a and a horizontal leg 21.2b, said second component 21.2 lying in a direction opposite to that of the first component such that the horizontal leg 21.1b of the first component and the horizontal branch 21.2b of the second component are aligned and nested one inside the other.

La branche horizontale 21.1b du premier composant et la branche horizontale 21.2b du deuxième composant ont des sections différentes et adaptées pour que l'emboitement soit possible avec un faible jeu. Par exemple, elles sont chacune formée par un profilé rectangulaire creux dont les dimensions externes du premier composant sont inférieures aux dimensions internes du second composant.The horizontal leg 21.1b of the first component and the horizontal leg 21.2b of the second component have different sections and adapted so that the interlocking is possible with a small clearance. For example, they are each formed by a hollow rectangular section whose dimensions external components of the first component are smaller than the internal dimensions of the second component.

La branche horizontale 21.2b du deuxième composant comprend par exemple une vis 25 permettant de solidariser lesdites branches horizontales 21.1b, 21.2b des premier et deuxième composant, par pression transversale.The horizontal leg 21.2b of the second component comprises for example a screw 25 for securing said horizontal branches 21.1b, 21.2b of the first and second component, by transverse pressure.

En outre, grâce à ses deux composants, la longueur de la première traverse 21 est réglable dans une plage de longueur prédéterminée.In addition, thanks to its two components, the length of the first cross member 21 is adjustable in a predetermined length range.

La branche verticale 21.1a est alors adaptée pour être enfilée sur l'extrémité supérieure 11b du premier montant 11, et le premier composant 21.1 de la première traverse 21 vient verticalement en butée contre ladite extrémité supérieure 11b.The vertical leg 21.1a is then adapted to be threaded on the upper end 11b of the first upright 11, and the first component 21.1 of the first cross member 21 comes vertically in abutment against said upper end 11b.

De même, la branche verticale 21.2a est adaptée pour être enfilée sur l'extrémité supérieure 12b du deuxième montant 11, et le deuxième composant 21.2 de la première traverse 21 vient verticalement en butée contre ladite extrémité supérieure 12b.Similarly, the vertical leg 21.2a is adapted to be threaded on the upper end 12b of the second upright 11, and the second component 21.2 of the first cross member 21 comes vertically in abutment against said upper end 12b.

La troisième traverse 23 comprend deux autres composants similaires à ceux de la première traverse. La troisième traverse 23 a ainsi une longueur réglable dans la même plage de longueur prédéterminée.The third cross 23 includes two others components similar to those of the first cross. The third cross member 23 thus has an adjustable length in the same predetermined length range.

Grâce à la construction décrite ci-dessus, la structure support 2 est réglable en largeur et en longueur, et peut donc être adaptée facilement à la taille du transformateur électrique 50, de telle sorte que les extrémités inférieures 11a, 12a, 13a, 14a des montants verticaux respectifs peuvent être placés autour du transformateur électrique, à faible distance de celui-ci, et entre ledit transformateur électrique 50 et des parois latérales de l'enceinte fermée.Thanks to the construction described above, the support structure 2 is adjustable in width and length, and can therefore easily be adapted to the size of the electrical transformer 50, so that the lower ends 11a, 12a, 13a, 14a of the respective vertical uprights may be placed around the electrical transformer, at a short distance thereof, and between said electrical transformer 50 and side walls of the closed enclosure.

De plus, les composants étant de dimension réduite, la structure support 2 peut être assemblée directement autour de la charge dans une enceinte fermée, sans qu'il y ait besoin d'espace autour et au dessus de la charge 50.In addition, the components being of reduced size, the support structure 2 can be assembled directly around the load in a closed enclosure, without the need for space around and above the load 50.

Le montage du dispositif découle de sa conception décrite ci-dessus, et les composants des différents montants et traverses de la structure support 2 peuvent être assemblées les unes aux autres dans un ordre quasi-quelconque que l'homme du métier aura peu de difficulté à déterminer.The mounting of the device stems from its design described above, and the components of the various amounts and crosses of the support structure 2 can be assembled to each other in an almost any order that the skilled person will have little difficulty in determine.

La structure de suspension 3 a déjà été partiellement décrite précédemment.The suspension structure 3 has already been partially described previously.

La poutre 4 de la figure 3 est réalisée en un seul profilé entre le premier palier 41 et le deuxième palier 42, de telle sorte que la poutre 4 soit très rigide et permette de soulever une charge très importante, par exemple supérieure à 1000 kg.The beam 4 of the figure 3 is made in a single section between the first bearing 41 and the second bearing 42, so that the beam 4 is very rigid and allows to lift a very large load, for example greater than 1000 kg.

En variante, la poutre 4 comprend deux composants formés de profilés creux, rectangulaires ou carrés, emboités l'un dans l'autre, de telle sorte que ladite poutre 4 soit télescopique, avec une longueur de poutre 4 réglable dans une plage de longueur prédéterminée, sensiblement identique à la plage de réglage de la longueur des première et troisième traverses 21, 23. La structure de suspension 3 est donc également réglable en longueur et peut être adaptée à la taille du transformateur électrique 50.Alternatively, the beam 4 comprises two components formed of hollow profiles, rectangular or square, nested one inside the other, so that said beam 4 is telescopic, with a length of beam 4 adjustable in a predetermined length range , substantially identical to the adjustment range of the length of the first and third crosspieces 21, 23. The structure of suspension 3 is also adjustable in length and can be adapted to the size of the electrical transformer 50.

Le deuxième palier 42 a une forme de H avec une branche horizontale 42a reliant deux branches verticales 42b, 42c qui sont écartées l'un de l'autre d'une distance sensible ment identique à la distance séparant les deux branches verticales 24.3b, 24.3c du troisième composant 24.3 de la quatrième traverse 24.The second bearing 42 has an H-shape with a horizontal branch 42a connecting two vertical branches 42b, 42c which are spaced from each other by a distance substantially identical to the distance separating the two vertical branches 24.3b, 24.3 c of the third component 24.3 of the fourth cross member 24.

Le deuxième palier 42 peut alors être engagé sur les troisième et quatrième guides 33, 34, sur lesquels il peut coulisser verticalement.The second bearing 42 can then be engaged on the third and fourth guides 33, 34, on which it can slide vertically.

Le premier palier 41 est identique au deuxième palier 42.The first bearing 41 is identical to the second bearing 42.

Les deux paliers 41, 42 permettre le coulissement sensiblement vertical, le long des guides 31, 32, 33, 34 de la structure de suspension 3.The two bearings 41, 42 allow the sliding substantially vertical, along the guides 31, 32, 33, 34 of the suspension structure 3.

Un premier vérin 6 est alors monté verticalement entre un troisième composant 22.3 de la deuxième traverse 22 et le premier palier 41. Un deuxième vérin 6 (voir figure 4) est monté verticalement entre le troisième composant 24.3 de la quatrième traverse 24 et le deuxième palier 42.A first cylinder 6 is then mounted vertically between a third component 22.3 of the second crossmember 22 and the first bearing 41. A second cylinder 6 (see FIG. figure 4 ) is mounted vertically between the third component 24.3 of the fourth cross member 24 and the second bearing 42.

Une plaque (non représentée) peut être montée entre les extrémités supérieures des branches verticales du troisième composant 22.3, 24.3. Ladite plaque comprend dans une portion sensiblement médiane une ouverture. Le vérin 6 traverse ladite ouverture de la plaque, et ne peut donc pas se déplacer latéralement et le fonctionnement du dispositif 1 est sécurisé.A plate (not shown) may be mounted between the upper ends of the vertical legs of the third component 22.3, 24.3. Said plate comprises in a substantially middle portion an opening. The jack 6 passes through said opening of the plate, and can not move laterally and the operation of the device 1 is secure.

Ces deux vérins 6 sont commandés simultanément pour soulever la structure de suspension 3 par rapport à la structure support 2 en appui sur le sol. Un compresseur hydraulique et des moyens d'actionnements (non représentés) sont connectés par un circuit 7 à chaque vérin 6, et grâce auxquels un opérateur peut provoquer l'actionnement des vérins et déplacement de la structure de suspension 3 entre la position abaissée représentée en figure 4 et la position relevée représentée en figure 5.These two jacks 6 are simultaneously controlled to lift the suspension structure 3 relative to the support structure 2 resting on the ground. A hydraulic compressor and actuating means (not shown) are connected by a circuit 7 to each cylinder 6, and thanks to which an operator can cause the actuation of jacks and displacement of the suspension structure 3 between the lowered position shown in FIG. figure 4 and the raised position represented in figure 5 .

Comme représenté en figure 4, le dispositif 1 est installé autour d'un transformateur électrique 50 qui repose sur le sol par ses galets 52. Les vérins 6 ont une longueur initiale, et la structure de suspension est en position abaissée.As represented in figure 4 , the device 1 is installed around an electrical transformer 50 which rests on the ground by its rollers 52. The cylinders 6 have an initial length, and the suspension structure is in the lowered position.

En figure 5, la structure de suspension 3 est en position est en position relevée.In figure 5 the suspension structure 3 is in the upright position.

Les vérins 6 sont allongés d'une première hauteur H1 et après le rattrapage de jeux verticaux entre les vérins 6 et la structure de suspension 3, puis entre la structure de suspension 3 et le transformateur électrique 50, ledit transformateur électrique 50 est soulevé dans la direction verticale D d'une seconde hauteur H2 inférieure ou égale à la première hauteur H1.The cylinders 6 are elongated by a first height H1 and after catching vertical clearances between the cylinders 6 and the suspension structure 3, then between the suspension structure 3 and the electrical transformer 50, said electrical transformer 50 is raised in the vertical direction D of a second height H2 less than or equal to the first height H1.

Sur cette figure, la position initiale, au sol, du transformateur électrique 50 est partiellement représentée en pointillé.In this figure, the initial position on the ground of the electrical transformer 50 is partially represented in dashed line.

La surface au sol sous le transformateur est ainsi complètement dégagée, et un bac de rétention de fluide 60 peut être manuellement placé sous ledit transformateur électrique 50.The floor area under the transformer is thus completely disengaged, and a fluid retention tank 60 can be manually placed under said electrical transformer 50.

Le bac de rétention 60 de fluide comprend au moins :

  • un fond 62 sensiblement rectangulaire 62, recouvrant une surface inférieure à la surface du premier rectangle R1 et ayant quatre bords latéraux,
  • quatre flancs latéraux 61 s'étendant vers le haut depuis lesdits bords.
The fluid retention tank 60 comprises at least:
  • a substantially rectangular bottom 62, covering a surface smaller than the surface of the first rectangle R1 and having four lateral edges,
  • four side flanks 61 extending upwardly from said edges.

Les flancs latéraux 61 ont une troisième hauteur H3 inférieure à la seconde hauteur H2. Le bac de rétention 60 peut être placé manuellement sous ledit transformateur électrique 50.The lateral flanks 61 have a third height H3 less than the second height H2. The retention tank 60 can be placed manually under said electrical transformer 50.

Le bac de rétention 60 présente un volume suffisant pour contenir le liquide présent à l'intérieur du transformateur électrique à diélectrique liquide.The retention tank 60 has a sufficient volume to contain the liquid present inside the liquid dielectric electrical transformer.

Un tel bac de rétention 60 peut être avantageusement réalisé par découpe dans une plaque, par exemple une tôle d'acier, puis pliage des flancs latéraux 61, puis soudage des quatre coins du bac de rétention 60. Le bac de rétention 60 ainsi réalisé est étanche et peu onéreux.Such a retention tank 60 may advantageously be made by cutting into a plate, for example a steel sheet, then folding the lateral flanks 61, then welding the four corners of the retention tank 60. The retention tank 60 thus produced is waterproof and inexpensive.

Alternativement, le bac de rétention 60 est réalisé par emboutissage d'une plaque de tôle. Le fond 62, les flancs latéraux 61 sont ainsi naturellement jointés ensemble de manière étanche et le bac de rétention 60 ainsi réalisé est également peu onéreux.Alternatively, the retention tank 60 is made by stamping a sheet metal plate. The bottom 62, the side flanks 61 are thus naturally joined tightly and the retention tray 60 thus produced is also inexpensive.

D'autres procédés de réalisation et d'autres matériaux pour réaliser ledit bac de rétention 60 peuvent être utilisés.Other methods of making and other materials for making said retention bin 60 may be used.

Le transformateur électrique 50 peut alors être reposé dans le bac de rétention 60. De cette façon, on n'utilise pas de grue et le transformateur électrique n'est pas déplacé sur le sol par roulement sur ses galets 52.The electrical transformer 50 can then be rested in the retention tank 60. In this way, no crane is used and the electrical transformer is not moved on the ground by rolling on its rollers 52.

Par conséquent, le dispositif 1 décrit précédemment permet de soulever la charge 50 à partir du procédé suivant :

  1. (a) on assemble le dispositif 1 autour du transformateur électrique 50,
  2. (b) on accroche la charge 50 aux moyens d'accrochage 5 du dispositif 1,
  3. (c) on met en pression les vérins 6, de sorte que les vérins 6 s'allongent et que le transformateur électrique 50 est soulevé de la seconde hauteur prédéterminée H2.
Consequently, the device 1 previously described makes it possible to lift the load 50 from the following method:
  1. (a) the device 1 is assembled around the electrical transformer 50,
  2. (b) the load 50 is attached to the attachment means 5 of the device 1,
  3. (c) the jacks 6 are pressurized so that the jacks 6 lengthen and the electrical transformer 50 is raised from the second predetermined height H2.

Ledit procédé comprend également les étapes suivantes :

  • (d) on positionne un bac de rétention 60 de liquide sur le sol sous le transformateur électrique 50,
  • (e) on relâche la pression des vérins 6, de sorte que les vérins 6 se raccourcissent et que le transformateur électrique 50 soit reposé dans ledit bac de rétention 60 de liquide.
Said method also comprises the following steps:
  • (d) positioning a retention tank 60 of liquid on the ground under the electrical transformer 50,
  • (e) releasing the pressure of the cylinders 6, so that the cylinders 6 are shortened and the electrical transformer 50 is rested in said retention tank 60 of liquid.

Grâce au dispositif et au procédé de mise en oeuvre décrit, il est possible de se conformer à la réglementation actuelle, c'est-à-dire de placer sous un transformateur électrique à diélectrique liquides déjà installé dans une enceinte fermée, un bac de rétention dudit liquide ayant des flancs latéraux.With the device and the implementation method described, it is possible to comply with the current regulations, that is to say to place under a liquid dielectric electrical transformer already installed in a closed chamber, a retention tank said liquid having lateral flanks.

Le transformateur n'est pas déplacé latéralement par roulement sur ses galets, ni soulevé par une grue impossible à installer dans l'enceinte fermée.The transformer is not moved laterally by rolling on its rollers, nor lifted by a crane impossible to install in the closed enclosure.

Le dispositif de levage est assemblé dans l'espace réduit de l'enceinte autour du transformateur électrique, et le transformateur est soulevé par le dispositif décrit, sensiblement verticalement dans cette enceinte fermée.The lifting device is assembled in the reduced space of the enclosure around the electrical transformer, and the transformer is lifted by the device described, substantially vertically in this enclosure closed.
