Description
La présente invention concerne le domaine de la construction des équipements de voies ferroviaires, en particulier les coeurs de croisement, et a pour objet un encastrement de la pointe mobile dans le berceau d'un coeur de croisement incorporé dans les longs rails soudés.The present invention relates to the field of construction of railway track equipment, in particular the crossing hearts, and has for object a embedding of the movable point in the cradle of a crossing heart incorporated in the long welded rails.
L'invention a également pour objet un procédé de réalisation d'un tel encastrement.The invention also relates to a method for making such an installation.
Un tel berceau est généralement constitué par un élément monobloc, de préférence en acier au manganèse, et par un élément formé par des rails réunis à la partie monobloc par soudure, ou par toute autre forme d'assemblage, ledit élément étant rigidifié par des platines posées par-dessous.Such a cradle is generally constituted by a one-piece element, preferably made of manganese steel, and by an element formed by rails joined to the part monobloc by welding, or by any other form of assembly, said element being stiffened by plates placed from below.
L'encastrement de la pointe mobile dans le berceau est particulièrement important dans les appareils incorporés en longs rails soudés, du fait qu'ils sont sollicités par des efforts verticaux dus au passage des véhicules et par des efforts de traction ou de compression dus aux variations de température dans les longs rails soudés. The installation of the movable point in the cradle is particularly important in appliances incorporated in long welded rails, because they are stressed by vertical forces due to the passage of vehicles and by traction or compression forces due to temperature variations in long welded rails.
On connaít, par EP-A-0 365 450 un encastrement de la pointe mobile dans le berceau d'un coeur de croisement incorporé dans les longs rails soudés, ledit ledit berceau étant composé de deux éléments, à savoir un élément monobloc et un élément constitué par deux rails et relié à la pointe mobile par un assemblage collé. Une liaison mécanique entre la pointe mobile et les deux rails du berceau est également connue par AT-A-343 711.We know, by EP-A-0 365 450 a recess of the moving point in the cradle of a crossing heart incorporated into the long welded rails, said said cradle being composed of two elements, namely an element monobloc and an element constituted by two rails and connected to the movable point by a bonded assembly. A relationship mechanical between the moving tip and the two rails of the cradle is also known from AT-A-343 711.
Par ailleurs, EP-A-0 282 796 et EP-A-0 298 950 décrivent une liaison mécanique entre la pointe et les pattes de lièvre d'un coeur de croisement à pointe fixe.Furthermore, EP-A-0 282 796 and EP-A-0 298 950 describe a mechanical connection between the tip and the hare's feet with a fixed point crossing heart.
Toutefois, les solutions préconisées par ces différents documents ne permettent pas d'assurer la pérennité de la reprise des sollicitations de compression ou de traction dues à la dilatation des longs rails soudés.However, the solutions advocated by these different documents do not ensure sustainability resumption of compression stresses or traction due to the expansion of long welded rails.
La présente invention a pour but de pallier cet inconvénient en proposant un encastrement de la pointe mobile dans le berceau d'un coeur de croisement incorporé dans les longs rails soudés, permettant d'obtenir une liaison durable entre les différents éléments et empêchant tout risque de rupture des moyens de serrage.The object of the present invention is to overcome this disadvantage by proposing a recess of the point movable in the cradle of an incorporated crossing heart in long welded rails, providing a connection durable between the different elements and preventing any risk of rupture of the clamping means.
A cet effet,l'encastrement de la pointe mobile dans le berceau d'un coeur de croisement incorporé dans les longs rails soudés, ledit encastrement permettant la transmission des efforts de dilatation des rails de voie courante audit berceau, tout en absorbant les efforts dus au roulement des véhicules, ledit berceau étant composé de deux éléments, à savoir un élément monobloc et un élément constitué par deux rails et relié à l'élément monobloc par soudure ou par toute autre forme d'assemblage, la liaison entre la pointe mobile et l'élément du berceau constitué par deux rails étant réalisée par un assemblage essentiellement mécanique au moyen de boulons, est caractérisé en ce qu'une part importante de l'effort de traction ou de compression engendré par les longs rails soudés est transmise par frottement d'entretoises solidaires de la pointe mobile et de l'élément du berceau constitué par les deux rails et s'appuyant au fond de l'âme des rails et en ce que l'effort résiduel est absorbé par des goupilles fendues coopérant avec des boulons à haute résistance serrés sur les entretoises, les rails et la pointe mobile, de telle sorte que les boulons d'assemblage ne soient sollicités qu'à la traction. For this purpose, the embedding of the movable tip in the cradle of a crossing heart incorporated in long welded rails, said recess allowing the transmission of the expansion forces of the track rails current to said cradle, while absorbing the forces due vehicle rolling, said cradle being composed of two elements, namely a monobloc element and an element consisting of two rails and connected to the monobloc element by welding or any other form of assembly, the connection between the moving point and the element of the cradle consisting of two rails being produced by an assembly essentially mechanical by means of bolts, is characterized in that a significant part of the tractive effort or compression generated by long welded rails is transmitted by friction of integral spacers of the movable point and the element of the cradle constituted by the two rails and resting at the bottom of the soul of rails and in that the residual stress is absorbed by cotter pins cooperating with high strength bolts tight on spacers, rails and movable tip, so that the assembly bolts are only applied to traction.
L'invention a également pour objet un procédé de réalisation de l'encastrement caractérisé en ce qu'il comporte une phase provisoire de montage des différents éléments de la pointe mobile et du berceau du coeur de croisement et une phase définitive de mise en place de moyens mécaniques de liaison démontable.The invention also relates to a method for carrying out the installation, characterized in that it includes a temporary assembly phase for the various elements of the moving point and the cradle of the heart of crossing and a final phase of setting up removable mechanical connection means.
L'invention sera mieux comprise, grâce à la
description ci-après, qui se rapporte à un mode de réalisation
préféré, donné à titre d'exemple non limitatif, et
expliqué avec référence aux dessins schématiques annexés,
dans lesquels :
Conformément à l'invention et comme le montrent
plus particulièrement, à titre d'exemple, les figures 1 à
4 des dessins annexés, l'encastrement de la pointe mobile
1 dans le berceau 2 d'un coeur de croisement incorporé
dans les longs rails soudés,
ledit encastrement permettant la transmission des efforts
de dilatation des rails de voie courante audit berceau,
tout en absorbant les efforts dus au roulement des véhicules,
ledit berceau 2 étant composé de deux éléments, à
savoir un élément monobloc 2' et un élément 2" constitué
par deux rails 3 et 4 et relié à l'élément monobloc 2'
par soudure ou par toute autre forme d'assemblage, la liaison
entre la pointe mobile 1 et l'élément 2" du berceau
constitué par deux rails 3 et 4 étant réalisée par un assemblage
essentiellement mécanique au moyen de boulons 7,
est caractérisé en ce qu'une part importante de l'effort
de traction ou de compression engendré par les longs
rails soudés est transmise par frottement d'entretoises 5
et 6 solidaires de la pointe mobile 1 et de l'élément 2"
du berceau constitué par les deux rails 3 et 4 et s'appuyant
au fond de l'âme des rails et en ce que l'effort résiduel
est absorbé par des goupilles fendues 11 et 12 coopérant
avec des boulons à haute résistance 7 et 8 serrés
sur les entretoises 5 et 6, les rails 3 et 4 et la pointe
mobile 1, de telle sorte que les boulons d'assemblage ne
soient sollicités qu'à la traction.According to the invention and as shown
more particularly, by way of example, FIGS. 1 to
4 of the accompanying drawings, the embedding of the
L'assemblage mécanique entre la pointe mobile 1
et l'élément 2" du berceau constitué par les deux rails 3
et 4
est avantageusement réalisé au
moyen d'entretoises 5 et 6 fixées, d'une part, sur la
pointe mobile 1 par l'intermédiaire de boulons à haute
résistance 7 et, d'autre part, sur les rails 3 et 4 de
l'élément 2" du berceau 2 par l'intermédiaire de boulons
à haute résistance 8 (figure 2). Les entretoises 5 et 6
se présentent chacune sous forme d'une paire de profilés
5', 5" et 6', 6" s'appuyant au fond de l'âme des rails et
dégageant des portées d'éclissage en vue du serrage des
boulons à haute résistance permettant l'obtention d'un
effort de frottement important âme sur âme, les profilés
5', 5" et 6', 6" de chaque paire étant reliés entre eux
respectivement au moyen de barrettes 9 et 10.Mechanical assembly between the
Les boulons à haute résistance 7 et 8 coopèrent
avec les profilés 5', 5" et 6', 6" des entretoises 5 et 6
et avec les rails 3 et 4 au moyen de goupilles fendues 11
et 12, en acier à ressort, servant, d'une part, de fourreau
auxdits boulons 7 et 8, dont les têtes 8' s'appuient
par l'intermédiaire de pièces 13 sur les faces externes
des rails 3 et 4 et dont les écrous 7" et 8", ainsi que
les têtes 7' des boulons 7 prennent appui sur les profilés
5', 5" et 6', 6" des entretoises 5 et 6 par l'intermédiaire
de rondelles 14 et, d'autre part, de pièce de
cisaillement aux efforts longitudinaux, par reprise des
sollicitations longitudinales en cas d'annulation du
frottement.
Les goupilles fendues traversent les rails 3 et
4 et la pointe mobile 1 par l'intermédiaire de perçages,
dont les diamètres sont à peine inférieurs à ceux desdites
goupilles. Il en résulte que les déplacements longitudinaux
des rails par rapport au coeur de croisement
sont extrêmement limités. En outre, les efforts longitudinaux
de cisaillement sont repris par les goupilles fendues
11 et 12, de sorte que les boulons à haute résistance
7 et 8 ne sont sollicités qu'à la traction.The cotter pins cross the
Les entretoises 5 et 6 transmettent par frottement,
de la pointe 1 au berceau 2, une part importante de
l'effort de traction ou de compression engendré par les
longs rails soudés. Le reste de ces efforts est absorbé
par la résistance au cisaillement des goupilles fendues
11 et 12 en acier à ressort formant les fourreaux des
boulons 5 et 6.The
Des essais effectués en laboratoire avec un
coefficient de sécurité de 1,5 par rapport aux efforts
considérés comme maximaux et avec un écart de 45° C par
rapport à la température d'équilibre des longs rails soudés
montrent que 80 % de l'effort de traction ou de compression
sont absorbés par le frottement à fond d'âme et
20 % par les goupilles fendues 11 et 12.Laboratory tests with a
safety factor of 1.5 compared to the efforts
considered maximum and with a deviation of 45 ° C by
relative to the equilibrium temperature of long welded rails
show that 80% of the tensile or compressive force
are absorbed by the deep-down friction and
20% by
L'assemblage de l'encastrement conforme à l'invention
est conçu de telle manière qu'en cas d'annulation
du frottement, les goupilles fendues 11 et 12 sont capables
d'absorber par cisaillement l'effort global.The assembly of the recess according to the invention
is designed in such a way that in the event of cancellation
friction,
L'invention a également pour objet un procédé
de réalisation de l'encastrement caractérisé en ce qu'il
comporte une phase provisoire de montage des différents
éléments de la pointe mobile 1 et du berceau 2 du coeur
de croisement et une phase définitive de mise en place de
moyens mécaniques de liaison démontable.The invention also relates to a method
for carrying out the installation, characterized in that it
includes a temporary assembly phase for the various
elements of the moving
Dans sa phase provisoire le procédé consiste à
fixer les profilés 5" et 6" sur la pointe 1, le profilé
5' sur le rail 3 et le profilé 6' sur le rail 4, à positionner
avec précision la pointe 1 et les rails 3 et 4, à
présenter les barrettes 9 et 10 et à les réunir respectivement
aux profilés 5, 5" et 6', 6" par des points de
soudure, puis à déposer les entretoises 5, 6 en écartant
