DISPOSITIF DE SOUDAGE POUR MONTER DES ECLISSES DE
RAIL EN CONTINU.
w La présente invention se rapporte à un dispositif dans le domaine des voies ferrées ayant des rails enterrés dans une plateforme, notamment aux voies pour tramway.
Les rails enterrés sont protégés par des chambres d'éclisses. Une chambre d'éclisses enveloppe le rail, sur toutes ses parties enterrées, latéralement et par en-dessous. Chaque chambre forme ainsi une étanchéité apte, notamment, à
éviter les courants électriques de fuite et une corrosion excessive du rail.
Cependant, les chambres d'éclisses sont fabriquées en atelier et mises en oeuvre sur chantier. Pour permettre leur transport et leur mise en uvre, elles sont donc de taille, et notamment de longueur, limitée. De ce fait, il y a une rupture d'étanchéité entre deux chambres voisines.
L'invention a pour but de proposer un procédé ou un dispositif pour permettre une étanchéité continue, sur toute la longueur nécessaire du rail.
Selon l'invention, un tel dispositif est un chariot pour souder une extrémité
d'une première éclisse avec une extrémité d'une deuxième éclisse caractérisé
en ce qu'il comprend un châssis et, fixés au châssis - des moyens de support pour les éclisses ; - I
WELDING DEVICE FOR MOUNTING SLIDERS
RAIL IN CONTINUOUS.
The present invention relates to a device in the field of way railways with rails buried in a platform, including tracks for tram.
The buried rails are protected by ribs. Room of fishbone covers the rail, on all its buried parts, laterally and by below. Each chamber thus forms a seal suitable, in particular, for avoid electrical leakage currents and excessive corrosion of the rail.
However, the ribs are made in the workshop and put into work on site. To allow their transport and their implementation, they are therefore of size, and in particular of length, limited. Because of this, there is a leakage between two neighboring rooms.
The object of the invention is to propose a method or a device for enabling a continuous seal, all the necessary length of the rail.
According to the invention, such a device is a carriage for welding an end a first splint with one end of a second splint characterized in that it comprises a frame and, fixed to the frame support means for the splints;
- 2 - une lame ; et, - un groupe de chauffe pour chauffer la lame.
Avantageusement, le chariot comprend des moyens de motorisation, de préférence un motoréducteur, pour déplacer la lame transversalement, entre une position active et une position escamotée. Le chariot peut en outre comprendre un groupe électrogène pour alimenter en électricité le groupe de chauffe et/ou les moyens de motorisation.
io De préférence, il comprend aussi des moyens de guidage longitudinal pour les éclisses à souder.
Les moyens de support peuvent comprendre un plateau, fixé sur le châssis, de préférence sensiblement horizontalement. Avantageusement, le plateau comprend une fente au travers de laquelle la lame s'étend vers le haut, depuis le groupe de chauffe. De préférence les moyens de support sont répartis de part et d'autre de la fente, de préférence de façon sensiblement égale.
Les moyens de support peuvent en outre comprendre au moins une allonge, amovible ou escamotable, pour prolonger longitudinalement le plateau, de préférence deux allonges, chacune pour supporter une éclisse respective.
Le châssis comprend avantageusement au moins trois pieds, de préférence quatre, deux pieds étant chacun équipé d'une roue respective.
Tout aussi avantageusement, le chariot comprend des moyens, de préférence des moyens de lorry, pour circuler sur une voie ferrée.
Plusieurs modes d'exécution de l'invention seront décrits ci-après, à titre d'exemples non limitatifs, en référence aux dessins annexés dans lesquels : - 2 - a blade ; and, - a heating group to heat the blade.
Advantageously, the carriage comprises means of motorization, preferably a geared motor, to move the blade transversely between an active position and a retracted position. The trolley can furthermore include a generator to supply electricity to the group of heater and / or motorization means.
Preferably, it also comprises longitudinal guiding means for the solder plates.
The support means may comprise a plate fixed to the frame of preferably substantially horizontally. Advantageously, the plateau includes a slot through which the blade extends upwards, since the heating group. Preferably the support means are distributed from go and other of the slot, preferably substantially equal.
The support means may further comprise at least one extension, removable or retractable, to extend the shelf longitudinally, preferably two extensions, each to support a respective splint.
The frame advantageously comprises at least three feet, preferably four, two feet each being equipped with a respective wheel.
Just as advantageously, the carriage comprises means, preferably means of lorry, to circulate on a railway.
Several embodiments of the invention will be described below, as non-limiting examples, with reference to the appended drawings in which:
3 wo 2018/134496 - - PCT/FR2018/050029 - la figure 1 est une vue schématique en perspective d'un chariot selon l'invention, prévu pour le soudage entre elles de deux chambres d'éclissage ;
- la figure 2 est une vue schématique en perspective du détail II de la figure 1.
La figure 1 représente un chariot I selon l'invention en position d'usage. Ce chariot est prévu pour le soudage d'éclisses 11, 12 en matériau thermofusible, notamment d'éclisses en polyéthylène haute densité (PERD).
Dans l'exemple illustré, le chariot comprend :
- un châssis 2;
- un plateau 3, soutenu par le châssis, le plateau et le châssis formant ensemble une table de travail ;
- un groupe électrogène 4, - une lame chauffante 5, - un groupe de chauffe 6, - un guide longitudinal 7, disposé sur le plateau, - un caisson transversal 8, disposé au-dessus du plateau ;
- des allonges 9 ; et, - une armoire de commande 10.
Le châssis est fait de tubes métalliques carrés. Il comprend quatre pieds verticaux 13, 14, s'étendant sensiblement verticalement depuis le plateau 3 vers le bas, en direction du sol. Deux pieds 13, disposés à l'avant, sont équipés chacun d'une roue. Les deux autres pieds 14, disposés à l'arrière sont prévus pour reposer directement sur le sol.
Les allonges 9 sont amovibles ou escamotables. En position d'usage, telle qu'illustrée à la figure 1, elles prolongent longitudinalement le plateau 3, l'une 3 wo 2018/134496 - - PCT / FR2018 / 050029 FIG. 1 is a schematic perspective view of a trolley according to the invention, intended for welding between them two chambers bolting;
FIG. 2 is a schematic perspective view of detail II of FIG.
1.
Figure 1 shows a carriage I according to the invention in use position. This carriage is provided for welding splints 11, 12 of hot melt material, especially of high density polyethylene splints (PERD).
In the illustrated example, the carriage comprises:
a chassis 2;
- a plate 3, supported by the frame, the plate and the chassis forming together a work table;
a generator 4, a heating blade 5, a heating group 6, a longitudinal guide 7, arranged on the plate, - A transverse box 8, disposed above the plate;
extensions 9; and, - a control cabinet 10.
The chassis is made of square metal tubes. It includes four feet vertical lines 13, 14, extending substantially vertically from the plate 3 down, towards the ground. Two feet 13, arranged at the front, are equipped each of a wheel. The other two feet 14, arranged at the back are provided to rest directly on the ground.
The extensions 9 are removable or retractable. In a position of use, such illustrated in Figure 1, they extend longitudinally the plate 3, Moon
- 4 -wo 2018/134496 PCT/FR2018/050029 à l'avant, l'autre à l'arrière. Les allonges et le plateau forment ensemble un support pour les éclisses 11, 12. Le guide 7 s'étend de part et d'autre du caisson.
Le caisson 8 comprend une ouverture 16, de sorte que le caisson forme une arche autour de cette ouverture, au-dessus du plateau. L'ouverture 16 est conçue pour qu'une éclisse disposée le long du guide 7 puisse traverser longitudinalement le caisson au travers de cette ouverture 16.
Le plateau 3 comprend une fente transversale 17. Cette fente est surplombée par le caisson 8 et le groupe de chauffe des disposé sous la fente. La lame 5 est disposée de sorte que ses plus grandes faces 18 regardent l'une vers l'avant, l'autre vers l'arrière du chariot 1, perpendiculairement à la direction longitudinale du guide 7. La lame s'étend verticalement depuis le groupe de chauffe, au l'avers de la fente 17.
Le chariot comprend en outre un motoréducteur, non représenté aux figures.
Le motoréducteur est prévu pour déplacer transversalement la lame 5 dans le caisson, entre une position active dans laquelle elle traverse l'ouverture 12 de haut en bas et une position latérale escamotée, sous le caisson 8, en dehors de l'ouverture 16.
Le groupe électrogène 4 est prévu pour fournir de l'énergie électrique au groupe de chauffe 6 et au motoréducteur.
On va maintenant décrire un procédé pour souder les deux éclisses 11, 12 entre elles.
D'abord, tel qu'illustré aux figures : - 4 -wo 2018/134496 PCT / FR2018 / 050029 in the front, the other in the back. The extensions and the plateau together form a support for the splints 11, 12. The guide 7 extends on both sides of the caisson.
The casing 8 comprises an opening 16, so that the casing forms a arch around this opening, above the plateau. The opening 16 is designed so that a splint arranged along the guide 7 can cross longitudinally the box through this opening 16.
The plate 3 comprises a transverse slot 17. This slot is overhung by the box 8 and the heater group arranged under the slot. The blade 5 is arranged so that its larger faces 18 look one towards the front, the other towards the rear of the trolley 1, perpendicular to the direction longitudinal direction of the guide 7. The blade extends vertically from the group of heats, on the obverse of the slit 17.
The carriage further comprises a geared motor, not shown in the figures.
The geared motor is designed to transversely move the blade 5 in the box, between an active position in which it passes through the opening 12 of up and down and a retracted lateral position, under the casing 8, outside of the opening 16.
The generator set 4 is intended to supply electrical energy to the heating group 6 and the geared motor.
We will now describe a method for welding the two fishplates 11, 12 between they.
First, as illustrated in the figures:
- 5 -wo 2018/134496 PCT/FR2018/050029 - on positionne la lame 5 en travers de l'ouverture 16, dans sa position active ;
- on dispose une extrémité 11A de la première éclisse 11 contre la lame 5, à
l'arrière de la lame ;
- on dispose une extrémité 12A de la deuxième éclisse 12 contre la lame, à
l'avant de la lame ;
- on fait chauffer la lame, de façon à provoquer une fusion des extrémités 11A, 12A.
Ensuite :
- on déplace la lame dans sa position escamotée ; et, - on met en contact les extrémités 11A, 12A, de sorte qu'elles se soudent l'une à l'autre.
Par ce procédé, répété autant de fois que l'on pose une nouvelle éclisse, on obtient une étanchéité continue entre les éclisses. Ce procédé peut être mis en uvre sur le chantier, au fur et à mesure de la pose des éclisses.
Dans l'exemple illustré le plateau est sensiblement horizontal ; il fait 0,7 mètre de large et 1 mètre de long ; il est disposé à 0,8 mètre au-dessus du sol.
Chaque allonge 9 fait 0,7 mètre de long. Ainsi, le plateau et les allonges constituent ensemble des moyens de support de 2,4 mètres, répartis de part et d'autre de la fente 17.
Bien sûr, l'invention n'est pas limitée aux modes de réalisation préférés qui viennent d'être décrits mais, au contraire, l'invention est définie par les revendications qui suivent.
Il apparaîtra en effet à l'homme de l'art que diverses modifications peuvent être apportées aux modes de réalisation décrits ci-dessus, à la lumière de l'enseignement qui vient de lui être divulgué. - 5 -wo 2018/134496 PCT / FR2018 / 050029 the blade 5 is positioned across the opening 16, in its position active;
an end 11A of the first splice 11 is arranged against the blade 5, at the back of the blade;
an end 12A of the second splint 12 is placed against the blade, the front of the blade;
the blade is heated so as to cause fusion of the ends 11A, 12A.
Then:
the blade is moved into its retracted position; and, the ends 11A, 12A are brought into contact so that they are welded together one to the other.
By this process, repeated as many times as we put a new splint, we gets a continuous seal between the fishplates. This process can be put in work on the site, as and when laying the fishplates.
In the example illustrated, the plate is substantially horizontal; he makes 0.7 metre wide and 1 meter long; it is 0.8 meters above the ground.
Each extension 9 is 0.7 meters long. Thus, the plateau and the extensions up set of support means of 2.4 meters, distributed on both sides of the slot 17.
Of course, the invention is not limited to the preferred embodiments which have just been described but, on the contrary, the invention is defined by the following claims.
It will be apparent to those skilled in the art that various modifications may to be to the embodiments described above, in the light of the teaching that has just been disclosed to him.
