Definitions
- the present invention relates to a carriage for mounting and dismounting a longitudinal line for supplying a mobile with electricity, of the type comprising three mutually integral longitudinal components, electrically conductive, having substantially constant cross sections, namely:
- a mounting body on a support having a mean longitudinal plane of symmetry and comprising a rigid flat base perpendicular to said plane and three wings arranged on the same side of the base due to a flat central wing disposed along said plane, and of two flat, elastically flexible lateral wings, arranged approximately parallel to said plane, respectively on either side thereof, the three wings being connected respectively to the base and having opposite a respective free end , the cross section of which has the shape of a beak facing the respective neighboring wing so that the beaks face two by two in a direction perpendicular to said plane,
- Such a line generally intended for supplying vehicles on rails, such as handling machines or electric drive units in places in which the installation of a traditional overhead catenary would present difficulties or dangers, in particular in tunnels in this which concerns the motor cars, makes it possible to cope with greater intensities than a line comprising a single contact wire.
- Such a cart has been manufactured and marketed since then, in particular under the reference 552 411 by the Applicant and comprises: - a rigid chassis having a mean longitudinal plane of symmetry,
- - Two lateral gripping members carried by the chassis disposed respectively on either side of said longitudinal plane, mutually symmetrical with respect to the latter in a respective determined position of rest with respect to the chassis, and capable of engaging with the free end of a respective corresponding lateral wing, on the side of the respective corresponding nozzle opposite to said longitudinal plane, at least in the direction of a distance relative to the latter from the respective position of rest, - Means for coercively moving, in a controlled manner, the lateral gripping members relative to the chassis in the direction of a distance from said longitudinal plane, perpendicular thereto, from the respective position of rest, and in the direction of approximation with respect to said longitudinal plane perpendicular thereto, in return to the respective position of rest,
- Such a carriage gives all satisfaction when it comes to mounting or dismounting, with respect to the mounting body or to an alignment of mounting bodies mutually assembled end to end, the single contact wire of the line in relation to which it is described in the aforementioned European patent application, to make this line and then repair it in the event of damage or repair it as part of a maintenance operation.
- an object of the present invention is to remedy this drawback and, to this end, the present invention provides an assembly and disassembly carriage in accordance with the aforementioned carriage but further characterized in that it comprises a central gripping member carried by the chassis, arranged along said longitudinal plane and capable of engaging with the free end of the central wing, between the corresponding spouts, at least in the direction of a distance from said longitudinal plane, on either side thereof, and in that the thrust member is capable of serving as a support for the two contact wires in the direction of a distance from the base of the mounting body parallel to said longitudinal plane.
- the carriage according to the invention makes it possible to control the position of the free end of each side wing relative to the free end of the central wing and, consequently, , to authorize a certain and easy engagement and release of the contact wires with respect to the respectively corresponding lateral wing and to the central wing of the or each mounting body, in any zone of the line.
- the means for moving the lateral gripping members disposed respectively on either side of the mean longitudinal plane of symmetry of the chassis can act simultaneously in particular in the direction of a distancing of these lateral members with respect to said longitudinal plane, that is to say also with respect to the central engagement member, to simultaneously separate the free ends of the two lateral wings vis-à-vis the free end of the central wing and authorize the simultaneous engagement or disengagement of the two contact wires, as if a carriage conforming to the teachings of the request was used of the aforementioned European patent but with the control offered by the characteristic provisions of the present invention.
- another object of the present invention is to take advantage of the possibility, offered by the carriage according to the invention, of controlling the position of the free end of each side wing relative to the free end of the central wing to remedy this other drawback of the carriage described in the aforementioned European patent application when it is used in connection with a line with two contact wires.
- the means for moving the lateral gripping members arranged on one side of said longitudinal plane are independent of the means for moving the lateral gripping members arranged on the other. side of said longitudinal plane.
- Such independence is particularly advantageous in that it allows, if necessary, to dismantle only one of the contact wires from an already installed line, for example if this wire has suffered damage, leaving the other contact wire in place in conditions suitable for continuing to use the power supply line for the time necessary to replace the wire thus removed, then reassemble a replacement wire without disturbing the contact wire left in place.
- This design of the carriage thus makes it possible to take full advantage of the method of retaining the contact wires by the mounting body.
- the lateral wings of the mounting body are elastically flexible to allow the aforementioned tightening stress tightening of the contact wires, by their free ends, on the free end of the central wing
- the latter can be comparatively rigid, by construction, that is to say due to its dimensioning transversely to the mean longitudinal plane of the mounting body, or even by destination, in the sense that even if it is elastically flexible like the lateral wings, the forces which the two contact wires apply to it at its free end due to the prestressing of the lateral wings are compensated by the effect of symmetry, so that this central wing does not undergo elastic bending at least as long as the wires contacts are present.
- the central wing can then possibly undergo such elastic bending until the force which it applies to the contact wire remaining balances the force applied to the latter by the corresponding lateral wing, but this elastic deflection of the central wing corresponds only to a short transient period in duration use of the line according to the invention, and it is easy to size the central wing, perpendicular to the mean longitudinal plane of symmetry of the mounting body, so that this deflection is not very noticeable.
- each lateral wing of a mounting body has a respective flat longitudinal face, approximately perpendicular to said plane, turned towards the base and placed in cantilever with respect to the respective lateral wing in the direction of a distance from said plane, it is advantageously provided that the means of removable mechanical connection between the chassis of the trolley according to the invention and the mounting body are rolling means on one and the other of said flat faces, as in the case of the trolley described in the aforementioned European patent application.
- the central gripping member, the lateral gripping members and, correspondingly, the mounting body are also preferably designed to be compatible with easy progression of the carriage.
- the central gripping member comprises at least one central roller disposed along said longitudinal plane, mounted for rotation relative to the chassis around an axis perpendicular to said longitudinal plane immobilized relative to the chassis meeting a translation along its said axis of rotation and capable of engaging peripherally in said groove of the central wing,
- the lateral gripping members comprise at least one pair of lateral rollers disposed respectively on either side of said longitudinal plane, mutually symmetrical relative to the latter in the respective position of rest, mounted for rotation relative to the chassis around of the same axis perpendicular to said longitudinal plane and capable of engaging peripherally in said groove of one, respectively, of the lateral wings, and that the means for moving the lateral gripping members comprise means for adjustable positioning of the lateral rollers along their said axis of rotation.
- the means for adjustable positioning of the lateral rollers to include:
- a respective screw mounted for rotation with respect to the chassis around their said axis of rotation, immobilized with respect to the chassis against translation along their said axis of rotation, in engagement with the respective slide by a thread and provided with means for maneuvering the rotation with respect to the chassis around their said axis of rotation.
- the axis of rotation of the central roller is coincident with that of the lateral rollers of said pair, between which is disposed the central roller.
- the carriage is also preferable for the carriage to be stabilized in orientation relative to the mounting body and, according to a preferred embodiment of the mounting carriage according to the invention:
- the central engagement member comprises two copies of said central roller, which are mutually symmetrical with respect to a determined transverse plane of the chassis, constituting a plane of symmetry for the thrust member,
- the lateral gripping members comprise two copies of said pair, mutually symmetrical with respect to said transverse plane, and
- the means for moving the lateral gripping members are provided in two respectively corresponding copies, mutually independent.
- the grip of the or each central roller in the groove of the free end of the central wing and that of each lateral roller in the groove of the free end of the corresponding lateral wing must be sufficient to allow transmit to the lateral wings, in the direction of a spacing with respect to the central wing at their free ends, an effort capable of increasing their elastic bending stress, in comparison with the state of prestressing in which they are placed to retain the contact wires.
- each groove has a V-shaped cross section as shown in the aforementioned European patent application
- the central roller at least one in number and each lateral roller of said pair at least at number one have a respective convex periphery, having a V shape when viewed in section through any plane inclining the respective axis of rotation.
- the thrust member is preferably designed to facilitate the aforementioned progression of the carriage.
- the thrust member is a roller mounted for rotation relative to the chassis around an axis perpendicular to said longitudinal plane and comprising two peripheral grooves, mutually symmetrical with respect to to said longitudinal plane, for receiving a respective one of the two contact wires, and the means for moving the thrust member comprise means for adjustable positioning of the axis of rotation of the roller in said transverse direction relative to the chassis.
- the adjustable positioning means of the axis of rotation of the roller comprise:
- a screw mounted for rotation on the slide about a transverse axis of said longitudinal plane, immobilized with respect to the slide against a translation along said transverse axis of rotation, in engagement with the chassis by a thread and provided with means for maneuvering in rotation relative to the chassis around said transverse axis of rotation.
- FIG. 1 shows a view, in side elevation, of an electrical supply line with two contact wires for the same mounting body, such as mounted, for example, in a railway tunnel for supplying an electric drive unit .
- FIG. 2 shows a view of this line in current cross section, along a plane marked in II-II in FIG. 1.
- FIG. 3 shows a view of this line in section through a transverse plane at the level of the joint between two longitudinally neighboring mounting bodies, along a plane marked in III-III in FIG. 1.
- Figures 4 and 5 show a carriage according to the invention, intended for mounting and dismounting one of the contact wires or two contact wires of the line illustrated in Figures 1 to 3 relative to the mounting body or to an alignment of such bodies, the carriage being illustrated in the position of use but in a state of rest, in which it does not apply to the free ends of the lateral wings a traction in the direction of a distance from the 'free end of the central wing, and being seen in section through transverse planes that have been identified respectively in IV-IV or VV in Figure 6 and according to which the line is also seen in section.
- FIG. 6 shows the carriage in section through a longitudinal plane parallel to the mean longitudinal plane, then common, of symmetry of the line and the carriage and identified in VI-VI in FIG. 4.
- FIG. 7 shows a detail of the carriage in section through a transverse plane identified in VII-VII in FIG. 6.
- Figures 8 and 9 show the carriage in a section identical to that of Figure 4, the carriage also being illustrated in the position of use but in an active state, in which it applies respectively to the free ends of the two lateral wings or to the 'free end of only one of them pulling in the direction of a distance from the free end of the central wing.
- the line will be considered subsequently as rectilinear and horizontal, it being understood that it can also be curvilinear and / or sloping; a person skilled in the art will easily adapt the description which will now be given to such cases, it being understood that it will be necessary, in the case of a line laid in a curve, to replace the notion of mean longitudinal plane of the line , especially his body mounting, by that of cylindrical surface defined by an average line of symmetry of each cross section of the line or of the mounting body. We will then consider as a longitudinal direction reference the average fiber of the line or of the mounting body.
- the power supply line 1 of which the longitudinal direction, here horizontal, has been designated by 2, and the mean longitudinal plane of symmetry, here vertical, has 3 a plurality of longitudinal mounting bodies 4 placed in the longitudinal extension of one another so as to be respectively symmetrical with respect to the plane 3, and these mounting bodies 4 are joined together end to end, in an integral manner, by means of 'fishplates 5, in a manner which will be described in more detail below.
- each body 4 has a longitudinal dimension, not referenced, of 12 meters and two longitudinally neighboring bodies 4 leave between them a longitudinal clearance 6 of the order of a few tenths of a millimeter to a few millimeters, but these values are not indicated. as a nonlimiting example and one could choose other values without departing from the scope of the present invention.
- the bodies 4 are suspended from the roof of the tunnel, not shown, by means of individual support elements, in practice electrical insulators, not shown, mutually spaced apart longitudinally by a predetermined distance. .
- Line 1 also comprises two longitudinal wires 7, electrically conductive, intended for contact with the bow of a pantograph carried by the powerplant to be supplied with electricity.
- These wires 7 are disposed respectively on either side of the plane 3 and mutually symmetrical with respect to it, and extend under the mounting bodies 4 over most of their longitudinal dimension and from one to the other. other mounting body 7 at or each set 6.
- Each wire 7 can have a dimension length of several hundred meters and thus extend under a longitudinal alignment of body 4 in the number required by the length of the tunnel, and continue outside the tunnel in the form of a traditional suspended catenary.
- the number of bodies 4 placed end to end will generally be greater than two; in certain particular cases, a single body 4 of suitable longitudinal dimension may also suffice.
- each of the wires 7 has in cross section the well-known, standardized form of a catenary wire, namely a generally circular shape hollowed out by two V-notches mutually symmetrical with respect to a plane.
- Each wire 7 thus has a generally cylindrical shape of revolution around this line 10 and comprises, in correspondence with the aforementioned notches, two grooves or longitudinal grooves 11 mutually symmetrical with respect to the plane 8 and arranged immediately above the plane 9.
- the cross section of the two wires 7 is constant over the entire longitudinal dimension of these wires 7, and the same is true of the cross section of each body 4 over the entire longitudinal dimension thereof, between two flat end faces 12, transverse, at which the clearance 6 is measured between two longitudinally neighboring mounting bodies 4.
- Each of the mounting bodies 4, which will now be described, consists of a single piece produced for example by extrusion; advantageously, in a manner known per se, it can be carried out in aluminum or aluminum alloy, as well as the edisses 5; in a manner also known, the wires 7 can advantageously be made of copper or a copper alloy; it is understood, however, that these materials are indicated only by way of nonlimiting examples.
- the mounting body 4 Upwards, taking into account the orientation of each mounting body 4 when it is suspended under the roof of a tunnel to suspend the wires 7, the mounting body 4 has a rigid flat base 13 perpendicular to the plane 3 and symmetrical with respect to it.
- this base 13 is defined respectively upwards and downwards by plane longitudinal faces 14, 15 perpendicular to the plane 3 and respectively symmetrical with respect thereto, whereas it is delimited in the direction of a distance from plane 3, respectively on either side thereof, by longitudinal edge faces 16, planar, parallel to plane 3 and mutually symmetrical with respect thereto.
- the mounting body 4 is suspended from the support insulators by the base 13, by means of clamps engaging the upper face 14, the faces 16 and marginal zones 17 of the lower face 15 , directly adjacent to a respective edge face 16.
- the mounting body 4 Projecting from the face 15, integral with the base 13 by being produced in a single piece with the latter, the mounting body 4 comprises three longitudinal, flat wings, at the rate of a central wing 18 arranged along the plane 3 and symmetrical with respect to the latter, and with two lateral wings 19 respectively disposed on either side of the plane 3, symmetrically to one another with respect to the latter, and approximately parallel to this plane 3.
- the central wing 18 and the two lateral wings 19 have a respective free end 20, 21.
- the connection of each wing 18, 19 with the base 13, the free end 20, 21 of each wing 18, 19 is rigid, but at least the lateral wings 19, and if necessary the central wing 18, can flex elastically between their connection to the base 13 and their free end 20, 21.
- each lateral wing 19 is delimited, respectively towards the plane 3 and in the direction of a distance with respect thereto, by a respective longitudinal face 22, 23 approximately plane and approximately parallel to the plane 3.
- the faces 22 and 23 of each wing 19, respectively, are connected to the lower face 15 of the base 13, between the marginal zones 17 of this lower face 15, by a respective cutaway 24, 25, and approach each other downwards. so as to allow the aforementioned elastic deflection of the wing 19, in particular in the direction of a distance relative to the plane 3 with regard in particular to its free end 21.
- the central wing 18 is delimited respectively on either side of the plane 3, in the direction of a distance from it, by two longitudinal planar faces 26, which are connected to the lower face 15 from the base 13 by a respective cutaway 27 and which approach each other down.
- This also results in a certain elastic flexibility of the central wing 18, perpendicular to the plane 3, but the central wing 18 behaves as a rigid whole with the base 13 under normal conditions of use of the mounting body 4, c 'That is to say, in the presence of two wires 7 under it, for reasons of symmetry, what a person skilled in the art will easily understand on reading the following description.
- each of the faces 26 is connected to a respective flat longitudinal face 28 which moves away from the plane 3 downwards, the two faces 28 being mutually symmetrical relative to the plane 3.
- each of these faces 28 is connected itself, by a cutaway not referenced, to a respective plane longitudinal face 29 which, from its connection with the face 28, approaches the plane 3 downwards.
- the faces 28 and 29 define, when viewed in cross section, the shape of a spout or a claw 32 turned in the direction of a distance from the plane 3 and having a standardized shape and dimensions to fit into a respective groove 11 of a respective wire 7.
- each face 29 is connected to a longitudinal, planar face 30 of the free end 20 of the wing 18, which face 30 is ascending from of its connection with the face 29 so that the two faces 30 converge mutually upwards and are mutually connected along the plane 3 by defining between the two spouts 32 a longitudinal groove 31 open downwards, having a cross section in V symmetrical about plane 3.
- each lateral wing 19 is itself connected downwards, at the level of the respective free end 21, to a plane longitudinal face 33 oblique to the plane 3, of which this face 33 approaches downwards.
- This face 33 is itself connected downwards to a flat longitudinal face 34 which approaches the plane 3 downwards with an obliquity, with respect to the latter, opposite than that of the face 28 situated on the same side of the plane 3 to connect itself downwards, by a cutaway, to a plane longitudinal face 35 which moves away from the plane 3 with a reverse obliquity, with respect to the latter, from that of the face 29 located in the same side of the plane 3.
- the face 35 is connected to a plane longitudinal face 36 rising in the direction of a distance from the plane 3, up to a distance from the latter greater than that which separates the face 23 of the lateral wing 19 considered, with an obliquity, relative to the plane 3, opposite to that of the face 30 located on the same side thereof.
- the faces 34 and 35 thus define at the free end 21 of this wing
- the two nozzles 32 and 37 are mutually symmetrical with respect to the plane 8 of the wire 7 which they hold together and are entirely or practically entirely arranged at the above the plane 9 of the latter and the corresponding lateral wing 19 is then placed in pre-stress of elastic deflection in the direction of a distance relative to the plane 3 by pressing its beak 37, towards the plane 3, against the wire 7 itself pressing towards this plane 3 against the spout 32 located on the same side of the plane 3 as the spout 37 considered.
- This prestress of elastic deflection can be predetermined by an appropriate dimensioning of each lateral wing 19 by giving the spouts 32 and 37, at the manufacture of the mounting body 3 and before the installation of the wire 7, a lower mutual spacing of a value predetermined at the mutual spacing of the grooves 11 of a wire 7 perpendicular to its plane 8, so that there results a predetermined clamping effect of each wire 7 between the two corresponding nozzles 32 and 37, resulting in the connection of each wire 7 with the mounting body 4, or more precisely with each of the mounting bodies 4 mutually juxtaposed longitudinally, and an intimate electrical conduction contact of each mounting body 4, over its entire longitudinal dimension, with each of the two wires 7.
- the electrical conduction at this level can be advantageously improved by the interposition of a cont grease. act between each spout 32, 37 and the corresponding groove 11 respectively.
- the wing 18 can be made to flex elastically under the effect of the thrust which it receives, by means of the remaining wire 7, of the wing lateral 19 corresponding, but the remaining contact wire 7 is retained sufficiently between the free ends 20 and 37 of the central wing 18 and the corresponding lateral wing 19 on the one hand so as not to risk accidentally detaching, which also facilitates the successive mounting of two wires 7 under each mounting body 4, and on the other hand to maintain an intimate electrical conduction contact with each body 4, which allows the use of the electrical supply line 1 with a single wire 7, for example in the event that a damage requires the other wire 7 to be dismantled.
- each face 36 is connected to a plane longitudinal face 38 approximately parallel to the plane 3 and more distant from the latter than the face 23 of the corresponding lateral wing 19, and this face 38 is connected to this face 23 by a flat longitudinal face 39 approximately perpendicular to the plane 3, thus turned upwards and placed in cantilever with respect to the lateral wing 19 in the direction of a distance from this plane 3.
- the face 36 in its zone closest to the face 38, this face 38 and the face 39 define at the free end 21 of the corresponding lateral wing 19 a rigid rim 40 in cantilever relative to the face 23 of the lateral wing 19, in the direction of a distance relative to the plane 3, which in particular makes it possible to hang on the mounting body 4, between two longitudinally successive insulators of suspension from the roof of the tunnel, a removable insulating cover not shown, covering the upper face 14 of the base 13, its edge faces 16, and hooking on the flanges 40 by covering the faces 23 of the lateral wings 19 but leaving half of each side clear, downwards and laterally contact wire 7 located under the plane 9.
- a longitudinal groove 41 open downwards, having a V-shaped cross section, symmetrical with respect to a respective plane 42 approximately parallel to plane 3, and the grooves 41 thus arranged in the flanges 40, in a position offset with respect to the corresponding respective spout 37, in the direction of a distance from the plane 3, can advantageously be used to strengthen the anchoring of the cover, by elasticity of the latter, on the ledges 40.
- Each of the sides 5 has the form of a longitudinal bar attached to the faces 22 of the two side wings 19 which it is intended to connect to each other, between these side wings 19 and the wings 18 of the corresponding mounting bodies 4, and it is retained pressing against these faces 22 by screwing, in tapped holes 46 which it has respectively opposite each of the holes 44, coaxially with the latter, of a respective bolt 45, advantageously provided with a lock washer 47 by which the head of this bolt 45 is supported on the face 23 of the corresponding lateral wing 19.
- each fishplate 5 may have a longitudinal dimension of the order of 40 cm, the holes 43 closest to the face 12 considered of each body 4 being spaced longitudinally of this face 12 by a distance of the order of 5 cm, and the holes 44 furthest from this face 12 being spaced longitudinally from the latter by a distance of the order of 15 cm.
- these figures are given by way of nonlimiting example, and different values could be chosen without departing from the scope of the present invention.
- edisse 5 has perpendicular to the plane 3 a thickness less than the spacing that each face 22 has with respect to the corresponding face 26, perpendicular to the plane 3, and the rods of the bolts 45 are themselves dimensioned so as not to risk coming into contact with the central wing 18.
- edisse 5 has a cross section at least equal to half the cross section of each mounting body 4 so that, considered as a whole, the two fishplates 5 ensuring the assembly of two longitudinally neighboring mounting bodies 4 offer a flow cross section at least equal to that offered by a mounting body 4.
- the assembly formed by the mounting bodies 4 assembled together by means of the ribs 5 not only ensures effective retention of the two wires 7 on their entire length, with the exception of games 6 which can be considered negligible in this respect, but it ensures in addition to the entire longitudinal dimension of line 1, the section required by the flow of current.
- each splice 5 a section of 1600 mm 2 , for a cross section of each mounting body 4 equal to 3120 mm 2 , each conductor 7 having generally a section of 107, 120 or 150 mm 2 ; naturally, other values could be chosen, these values having no impact on the present invention.
- the mounting bodies 4 can advantageously be made capable of preventing, by bending the line 1 between two longitudinally successive support insulators, the conductive wire 7 taking on a corrugated configuration.
- each mounting body 4 is manufactured so that at rest, that is to say before suspension from the roof by the insulators and before mounting of the wires 7, it has a predetermined deflection such that after suspension by means of the insulators and attachment of the wires 7, this deflection is canceled out under the effect of the weight of the mounting body 4 and of the wires 7.
- each mounting body 4 The determination of the arrow to be given to each mounting body 4 during its manufacture falls within the normal abilities of a person skilled in the art, and such a design of the body 4 makes it possible to avoid a multiplication of suspension insulators, which are usually provided in excess to combat any tendency of the line to flex between them.
- the carriage 48 is essentially placed under the latter, and it is suspended locally to a mounting body 4, or the case appropriate to two longitudinally neighboring mounting bodies 4 if it is located at the mutual connection between them, by means of means also allowing its longitudinal movement preferably by rolling, in a determined position of use which is illustrated in the figures 4 to 9 and which will serve as a reference after the description of the carriage 48.
- the carriage 48 is suspended from a single mounting body 4, it being understood that its suspension to two successive mounting body 4 is carried out under identical conditions and its progression along line 1 causes it to pass without difficulty from a mounting body 4 to a mounting body 4 longitudinally adjacent, as will be readily understood on reading the following description.
- the carriage 48 comprises a rigid frame 49 situated essentially at a level lower than that of line 1 and having the approximate general shape of a rectangular parallelepiped symmetrical with respect to a longitudinal plane which merges with the mean longitudinal plane 3 of symmetry of line 1 and to which reference 3 will therefore also be assigned.
- the chassis 49 also has a transverse plane of symmetry 50, the notions of longitudinality and transversality referring to the longitudinal direction of line 1.
- the frame 49 is formed by an assembly integral with two rigid flanges 51, flat, approximately rectangular, mutually identical, mutually symmetrical with respect to the plane 3 to which they are parallel and respectively symmetrical with respect to in plane 50, and four rigid, rectilinear spacers, perpendicular to plane 3 and mutually connecting the two flanges 51, on the basis of two longitudinally extreme spacers 52, mutually symmetrical with respect to plane 50, and two longitudinally median spacers 53, also mutually symmetrical with respect to the plane 50.
- spacers 52 and 53 maintain between the flanges 51, perpendicular to the plane 3, a mutual spacing greater than that which separates mutually, perpendicular to this plane 3, the faces 38 of the flanges 40 from the free ends 21 lateral wings 19 when these free ends 21 are t sufficiently spaced from the free end 20 of the central wing 18, perpendicular to the plane 3 to completely release the beaks 32 and 37 from the grooves 11 of the wires 7, naturally within limits such as the deflection of the wings lateral 19 remains in the elastic range.
- each of the flanges 51 has a rectilinear and longitudinal upper edge 153, arranged for example at a level corresponding to the mean level of the faces 36 of the free ends 21 of the lateral wings 19.
- each flange 51 bears a respective longitudinal bar 54 which is symmetrical with respect to the plane 50 and runs along the upper edge 153 while coplanarly extending the respective flange 51 upwards to a level higher than that of the faces 39 of the edges 40 of the free ends 21 of the lateral wings 19, without however reaching the level of the base 13 and along one, respectively, of the faces 38 while respecting a clearance with respect to the latter, in a direction perpendicular to the plane 3, so as to neither hinder the longitudinal movement of the carriage 48 relative to the line 1, nor the spacing of the free ends 21 of the lateral wings 19 relative to the end free 20 of the central wing 18 under conditions suitable for disassembling and reassembling the wires 7.
- each of the bars 54 bears integrally two journals 55 with respective axes 56 perpendicular to the plane 3, towards which each of the journals 55 is turned.
- each of the journals 55 has dimensions such that it respects with respect to the lateral wing 19 respectively located on the same side of plane 3 sufficient play, perpendicular to plane 3, to allow the aforementioned spacing of the free ends 21 of the side wings 19 relative to the free end 20 of the central wing 18.
- the two pins d '' the same bar 54 are mutually symmetrical with respect to the plane 50, just as each pin 5 of a bar 54 is symmetrical with a pin 55 respective to the other bar 54 relative to plane 3, that is to say also coxial with this pin, of which it is symmetrical with respect to plane 3.
- Each of the pins 55 ensures mounting with free rotation around the respective axis 56, without any other possibility of displacement relative to the respective bar 54, of a respective roller 57 resting down on the face 39 of the flange 40 of the free end 21 of the wing 19 located on the same side of the plane 3.
- the rollers 57 are dimensioned so as to respect a clearance, perpendicular to the plane 3, relative to the lateral wing 19 respectively located on the same side of this plane even when the free end 21 of this lateral wing 19 is sufficiently spaced from the free end 20 of the central wing 18 to allow the disassembly and reassembly of the wires 7.
- the four rollers 57 ensure both the attachment of the carriage 48, by its chassis 49, to the flanges 40 of the two free ends 21 of the side wings 19 and the longitudinal guidance of the carriage 48 relative to the mounting body 4 , by rolling on the faces 39 of the flanges 40.
- each bar 54 with the flange 51 respectively corresponding is effected by means of means which make it possible to offset the bars 54 and the rollers 57 which they carry, relative to the position which comes from 'be described and which corresponds to their position of use, sufficient to allow the operations of hooking the carriage 48 and of detaching the latter relative to the mounting body 4.
- Such means are known in themselves in case of carriages similar to the carriage 48 but intended for the assembly and disassembly of the single contact wire of a rigid monofilament catenary, namely more precisely in a first embodiment equipping the carriages marketed under the reference 552 020 by the company DELACHAUX SA , 119 Avenue Louis Roche, F92231 GENNEVILLIERS, and in a second embodiment equipping the trolleys sold under the reference 552 411 by the applicant.
- These means which have been designated as a whole by the reference 58, will therefore not be described and it is understood that they could be replaced by other means ensuring the same function.
- Each flange 51 also has two front edges 59, rectilinear and transverse, mutually symmetrical with respect to the plane 50 and in the immediate vicinity of each of which is located a respective end spacer 52, and a lower edge 60 longitudinal but convex downwards, comprising two rectilinear, longitudinally extreme sections 61 each of which is connected to one, respective, of the front edges 59 and, although approximately longitudinal, slopes downward from its connection with this respective front edge 52, and which are mutually symmetrical with respect to the plane 50, and with a longitudinally median pan 62 as for it rectilinear and longitudinal, having longitudinally dimensions substantially smaller than those of each of the panels 61.
- each flange 51 is pierced, perpendicular to the plane 3, with a respective hole 63 for hooking a shackle allowing the carriage to be driven along from line 1, by a works train.
- the axes 56 of each pair of rollers 57 which correspond by mutual symmetry with respect to the plane 3 are located in the same respective transverse plane 64, and the two transverse planes 64 thus defined are mutually symmetrical with respect to the plane 50, each of between them passing between one, respectively, of the extreme spacers 52 and that of the median spacers 53 which is respectively the closest, substantially at the same longitudinal distance from these two spacers 52 and 53.
- the two flanges 51 are pierced right through with a respective hole 67 delimited by a respective inner peripheral face 68 of cylindrical revolution around the respective axis 66, the faces 68 of the different holes 67 having the same diameter.
- the flanges 51 carry, with the possibility of relative free rotation about the respective axis 66, a respective train 69 of three rollers at the rate of a central roller 70, arranged along the plane 3 that it overlaps and with respect to which it is symmetrical, and of two lateral rollers 71 parallel to the plane 3 and mutually symmetrical with respect to the latter.
- the two trains 69 of rollers 70, 71 are mutually identical, and only one of them will be described, with particular reference to FIG.
- the carrier shaft 72 has a central section 73 which is delimited, in the direction of a distance from the axis 66, by an outer peripheral face 74 commonly having a cylindrical shape of revolution around the axis 66 with a diameter which is for example substantially identical to that of the inner peripheral face 68 of the holes 67.
- the section 73 has a dimension slightly less than the dimension which separates the flanges 51 from each other perpendicular to plane 3 and, in the direction of a distance from it, respectively on either side of it, the face 74 is connected to a shoulder 75 plane, annular of revolution about the axis 66 to which it is perpendicular; the two shoulders 75 are thus mutually symmetrical relative to the plane 3, turned in the direction of a distance relative to the latter and respectively placed slightly recessed towards the plane 3 relative to the flange 51 situated on the same side of it this.
- the carrier shaft 72 has an end section 76 delimited, in the direction of a distance from the axis 66 , by a cylindrical outer peripheral face 77 of revolution about the axis 66 with a diameter smaller than that of the face 74, to which the face 77 is connected by one, respectively, of the shoulders 75, and that of the inner peripheral face 68 of one, respective, of the holes 67 by means of which the end section 76 passes through the flange 51 respectively corresponding, so as to be partially cantilevered with respect to this flange 51 in the direction of a distance from the plane 3.
- each end section 76 is connected, in the direction of a distance from the axis 3, to a face extreme 78 disc-shaped perpendicular to the axis 66, and the two end faces 78, which are mutually symmetrical with respect to the plane 3, are mutually spaced along the axis 66 by a distance greater than the overall dimension which, perpendicular to the plane 3, the assembly formed by the two flanges 51 assembled mutually by the spacers 52 and 53.
- each end section 76 of the carrier shaft 72 is ensured by means of a respective coaxial sheath 79 which, in addition, ensures the maintenance of the carrier shaft 72, relative to flange 51, in a relation of symmetry with respect to plane 3.
- each sleeve 79 is placed in guide contact with relative rotation about the axis 66 respectively with a portion of the outer peripheral face 77 of a respective end section 76 and with a portion of the outer peripheral face 74 of the central section 73 of the carrier shaft 72.
- each sleeve 79 are mutually connected by a plane shoulder, annular of revolution about the axis 66 to which it is perpendicular, this shoulder 62 being turned towards the p lan 3 and in support, flat but in a relationship allowing the rotation of the sheath 79 around the axis 66 relative to the carrier shaft 72, against a respective shoulder 75 of the latter.
- each sleeve 79 is connected to a respective end face 83 which is flat, annular of revolution around the axis 66 to which it is perpendicular, which face 83 is turned in the direction of a distance from the plane 3.
- the distance separating each other, along the axis 66, the face 83 and the shoulder 82 is less than the distance separating each other, along this axis, the end face 78 of the corresponding end section 76 and the shoulder 75 connecting this end section 76 to the central section 73, so that the end section 76 protrudes in the direction of a distance from the plane 3 , along the axis 66, relative to the end face 83 of the corresponding sheath 79.
- the inner peripheral face 81 has, for its part, along the axis 66, a dimension less than half the dimension separating mutually, along this axis, the shoulders 75 of the carrier shaft 72, so that this face 81 does not reach the plane 3, towards which it is connected to another end face 84 of the sleeve 79, which is planar, annular of revolution about the axis 66 to which it is perpendicular, and thus turned towards the plane 3.
- the faces 84 of the two sleeves 79 are thus turned towards one another and mutually symmetrical with respect to the plane 3 so as to leave subsist between them, along the axis 66, a space 85 which straddles the plane 3 and is equally distributed on either side of it.
- each of the end faces 83, 84 of each sleeve 79 is connected to a respective external peripheral face 86, 87 thereof, turned in the direction of a distance relative to axis 66.
- Each of these outer peripheral faces 86 and 87 has two sections mutually juxtaposed along the axis 66, in a manner which will be detailed, but, in general, the section 87 has dimensions greater than those of the section 86 perpendicular to the axis 66, and these two sections 86 and 87 are mutually connected by a flat shoulder 89, annular of revolution around the axis 66 to which it is perpendicular, this shoulder 89 being turned in the direction of a distance from the plane 3 and offset in this direction relative to the shoulder 82 of the sleeve 79.
- this offset is equal to half the difference between the distances which respectively separate, along this axis, the two shoulders 75 of l carrier shaft 72 and the two flanges 51, so that each of the shoulders 89 is supported, in the direction of a distance with respect to the axis 3, against a respective flange 51, in an authorized rotation sant a rotation of the respective sheath 79 around the axis 66 relative to this flange 61 as well as relative to the carrier shaft 72, which ensures a timing of the carrier shaft 72 and each of the corresponding sleeves 79 relative to the two flanges 51, so that the carrier shaft 72 is symmetrical by relative to plane 3 and that the two sleeves 79 which are associated therewith are mutually symmetrical with respect to this same plane 3.
- each of the outer peripheral faces 86, 87 has a cylindrical shape of revolution around the axis 66, the diameter of the section 91 of the face 87 being greater than that of the section 90 of the face 86, which is identical to the diameter of the inner peripheral face 68 of a hole 67 of the flanges 51 so that each section 90 is placed in contact with the inner peripheral face 68 of a respective hole 67, in a relation of guidance to the relative rotation about the axis 66, which ensures at the same time the coaxiality of the respective sheath 79 and that of the carrier shaft 72 with respect to each of the two holes 67 of the same axis 66.
- the section 90 of the outer peripheral face 86 has a dimension at least equal to the thickness of a flange 51, measured along the axis 66, but less than the dimension separating each other along this axis, the end face 83 and the shoulder 89 of the sheath 79 so that the latter has, in overhang relative to the corresponding flange 51, in the direction of a distance from the plane 3, a second section 92 from its outer peripheral face 86, which presents perpendicularly to the axis 66 the shape of a square offering grip to a removable key 88, visible in FIG. 5, allowing each sheath 79 to rotate at will, independently of the others, around of the axis 66 relative to the flanges 51 and to the carrier shaft 72 without relative displacement along this axis 66.
- each sleeve 79 has a second section 93 which connects its first section 91 to the face 84 and has the form of a thread with a diameter greater than that of the section 91, making it possible to transform the aforementioned movement of rotation of the sheath 79 around the axis 66 in a translational movement, along this axis, relative to the sheath 79 considered, the carrier shaft 72 and the flanges 51, of a respective slide 94, provided at the rate of one per sheath 79 and mounted to slide thereon along the axis 66, while being immobilized against rotation about this axis 66 relative to the flange 51 corresponding to this sheath 79.
- each slider 94 has the general shape of an annular sleeve of revolution around the axis 66, towards which the slider 94 is delimited by an inner peripheral face 95 comprising two sections 96, 97 succeeding each other in this order, in the direction of a distance with respect to the plane 3.
- the section 96 carries a complementary thread of the thread of the section 93 of the outer peripheral face 87 of the sleeve 79, with which the slide 94 cooperates thus in the manner of a nut with a screw, and has perpendicular to the plane 3 a dimension identical to that of this section 93;
- the section 97 has a cylindrical shape of revolution around the axis 66 with a diameter identical to that of the section 91 of the outer peripheral face 87 of the sleeve 79, but with a dimension, perpendicular to the plane 3, less than that of the section 91 by a distance at least equal to that from which it is necessary to separate the free end 21 of a lateral wing 19 from the body 4, relative to the free end 20 of the central wing 18, for release the wire 7 from the corresponding nozzles 32, 37 or engage such a wire 7 between these nozzles 32, 37.
- the tapped section 96 of the inner peripheral face 95 of the slider 94 is connected to an end face 98 of the latter, which is planar, turned towards plane 3 and annular of revolution about the axis 66 to which it is perpendicular.
- the face 98 coplanarly extends the face 84 of the sleeve 79 in the direction of a distance from the axis 66.
- the slide 94 is also delimited by a flat face 99, annular of revolution about the axis 66 to which it is perpendicular.
- This face 99 is turned in the direction of a distance relative to the plane 3, that is to say placed opposite the flange 51 located on the same side of this plane 3, while respecting this flange 51, in the aforementioned position of rest, a clearance 100 whose dimension along the axis 66 is equal to the aforementioned stroke which it is necessary to cause the free end 21 of a lateral wing 19 to be made relative to the free end 20 of the central wing 18, to release a contact wire 7 or put it in place.
- this clearance 100 is the maximum value of the possible stroke of the slide 94 relative to the sleeve 79, that is to say also relative to the carrier shaft 72 and the flanges 51, if a rotation is applied to the sleeve 79 capable of causing mutual unscrewing of the sections 93 and 96.
- the section 97 of the inner peripheral face 95 of the slide 94 slides on the section 91 of the outer peripheral face 87 of the sleeve 79, thereby ensuring the stability of the coaxiality of the slide 94 relative to the sleeve 79, to the support shaft 72 and to the holes 67 of the flanges 51.
- the pin 101 has an outer peripheral face 104 cylindrical of revolution around the axis 102, between the corresponding flange 51 and an end face 105 which is plane, perpendicular to the axis 102 and turned towards the plane 3, and the hole 103 is delimited towards the axis 102 by an inner peripheral face 106 of cylindrical revolution about the axis 102 and of a diameter identical to that of the outer peripheral face 104.
- the slider 94 In the direction of a distance from the axis 66, the slider 94 is delimited by an external peripheral face 107 whose shape, of revolution around the axis 66, can be chosen from a wide range of possibilities to allow the setting on the slide 94, against any relative displacement parallel to the axis 66 and perpendicular to the latter, of the inner cage, not shown in detail, of a thrust bearing 108 including the outer cage, also not shown in detail, carries one, respectively, of the side rollers 71 with the possibility of free rotation about the axis 66 relative to the slide 94 without other possibility of relative movement.
- the mounting, for this purpose, of the lateral roller 71 by means of bearings 108 on the outer peripheral face 107 of the slide 94, the conformation of this face 94 for this purpose and the direction of mounting of the thrust bearing 108 are aptitudes normal to a person skilled in the art, it being understood that the thrust bearing 108 must be mounted on the slide 94 so as to allow the transmission from the latter, to the lateral roller 71, of a force going in the direction of a distance from the plane 3.
- the roller 71 and the bearing 108 ensuring its mounting on the slider 94 has dimensions smaller than those of the slider 94, and the roller 71 is disposed relative to this slider 94, along the axis 66, of such that, when the slide 94 occupies its rest position, the roller 71 engages peripherally in the groove 41 of the free end 21 of the wing 19 of the mounting body 4 which is located on the same side of the plane 3 while this wing 19 has its shape for retaining a wire 7 between the spouts 32 and 37, as illustrated in FIG. 4 with regard to the two lateral rollers 71 visible in this figure, and in FIG. 9 in as regards the lateral roller 71 located to the left of this figure.
- each lateral roller 71 has, in the direction of a distance from the axis 66, an annular periphery 109 of revolution around the axis 66 and this periphery 109 has, when viewed in section by any plane including the corresponding axis 66, a convex shape in the direction of a distance from the axis 66, and more precisely a V-shape which is symmetrical with respect to a plane 110 perpendicular to the axis 66 and is substantially complementary to that of the cross section of a groove 41 so that, in the aforementioned rest position of a slide 94, this shape matches at least approximately that of the groove 41 of the free end 21 of the lateral wing 19 situated on the same side of the plane 3, while this wing 19 occupies with respect to the central wing 18 its position for retaining a wire 7 between their beaks 32, 37, the planes 110 and 42 coinciding then at least approximately.
- each lateral roller 71 must have, with reference to the axis 66, a diameter related to this function.
- this diameter is such that the distances which, perpendicular to the axes 66 and 56 situated in the same plane 64, separate the periphery 109 of a lateral roller 71 and the non-referenced periphery of the roller 57 which is superposed therefrom are approximately equal to the distance which separates each other, along a transverse direction parallel to plane 3, the bottom of a groove 41 and the longitudinal, plane face 39 of the same flange 40.
- the central roller 70 is for its part intended to come into engagement with the groove 31 of the free end 20 of the central wing 18.
- a periphery 111 having a shape of revolution around the axis 66 and becoming thinner in the direction of a distance from that -this, with a convex shape when this periphery 111 is seen in section through any plane including the axis 66, and more precisely a V shape substantially complementary to that of the cross section of the groove 31.
- the diameter of the periphery 111 of the central roller 70 is determined by a person skilled in the art, so that this periphery 111 is engaged in the groove 31 and cooperates with the latter to ensure the coincidence of the mean longitudinal plane of symmetry of the carriage 48 with the mean longitudinal plane 3 of symmetry of the line 1 and in particular of the mounting body 4 as soon as the carriage 48 is suspended from the latter by its rollers 57, bearing on the faces 39 of the two flanges 40.
- the roller 70 is mounted for free rotation about the axis 66 relative to the carrier shaft 72, without any other possibility of relative displacement and independently of the two lateral rollers 71 which are coaxial with it.
- the carrier shaft 72 carries integrally, inside the space 85, thanks to arrangements known to a person skilled in the art and which will therefore not be detailed, an inner cage 112 of a thrust bearing 113 in both directions of the axis 66.
- This bearing 113 arranged symmetrically with respect to the plane 3 which it overlaps, moreover has an outer cage 114 made integral, by any appropriate means, known to a person skilled in the art and therefore not described, central roller 70 which has for this purpose, towards the axis 66, an inner peripheral face 115 annular of revolution around the axis 66 and suitably shaped.
- the central roller 70 advantageously plays a role of stop preventing the slides 94 associated with the two side rollers 71 which are coaxial with it from exceeding their rest position in the direction of a comparison with plan 3.
- the inner peripheral face 115 of the central roller 70 is connected to an end face 116 which is flat, annular of revolution about the axis 66 to which it is perpendicular.
- the two faces 116 mutually symmetrical with respect to the plane 3 and mutually spaced, perpendicularly thereto, by a distance equal to that which mutually separates the faces 84 of the two sleeves 79 of the same axis 66 as the central roller 70, are each placed opposite the face 98 of the respective one of the corresponding sliders 94 which, in this way, abuts by this face 98 against the face 116, in the direction of approximation towards the axis 3, if the there is a tendency to force on this slide 94, by means of the key 88 via the corresponding sheath 79, in the direction of approximation relative to the axis 3 once the rest position has been reached.
- the end faces 116 of the central roller 70 are connected to an outer peripheral face 117 thereof, which is cylindrical of revolution around the axis 66 with a diameter which, for example, is identical to that of the zones of the outer peripheral faces 107 of the slides 94 which are directly adjacent thereto, and the periphery 111 of the roller 70 is connected to this face 117 by two planar shoulders 118, annular of revolution about the axis 66 to which they are perpendicular, these two shoulders 118 being mutually symmetrical with respect to plane 3, turned in the direction of a distance from it, and mutually spaced by a distance less than that which separates the faces 116 parallel to the axis 66.
- each lateral roller 71 can be adjusted independently of the others in its position in the direction of a distance from plane 3, from its rest position.
- any position of a lateral roller 71 away from the plane 3, including the rest position, constitutes a stable position any means can be provided and it can in particular be provided that the pitch and the surface condition of the threading of the section 93 and of the tapping of the section 96 make the screwing of each sleeve 79 into the corresponding sliders 94 irreversible, unless a voluntary action is made using the key 88 on the section 92, of square section, of the peripheral face outer 86 of this sheath 79.
- the median spacers 53 carry a nut 120 in which is engaged , by a thread 122, a coaxial screw 123 which has below the spacers 53 a square 124 for maneuvering by means of a key similar to the key 88.
- the screw 123 has an upper end secured in translation along the axis 119, but with the possibility of free relative rotation about this axis 119, with a slide having the shape of a yoke 120 comprising two parallel cheeks 121 occupying mutually symmetrical positions with respect to the axis 119.
- Each of these cheeks 121 bears integrally, projecting in the direction a distance from this axis 119 along the same axis 124 perpendicular thereto, a rigid finger 125 engaged by a respective terminal lug 126, coaxial, in a respective rectilinear lumen 127, arranged respectively in each of the flanges 51, along the plane 50, and elongated parallel to the axis 119, so that the engagement of the lugs 126 in the openings 127 maintains the two cheeks 121 in a position mutually symmetrical with respect to the plane 3.
- the pitch of the thread 122 of the screw 123 and that of the nut 120 are irreversible, so that, under the normal conditions of use which will be described later, the yoke 120 retains with respect to the chassis 49 of the carriage 48 and with respect to line 1 the position which is given to it voluntarily by rotation of the screw 123 about the axis 119 with respect to the nut 120.
- a roller 128 mounted journalled around the axis 124 on one and the other so as to be able to rotate freely around the axis 124 relative to the yoke 120 without any other possibility of relative movement.
- the face 129 has two extreme sections 130, with reference to the axis 126, mutually symmetrical with respect to the plane 3, and a median section 131, with reference to the axis 126, overlapping the plane 3 symmetrically with respect thereto , and these three sections 130, 131 are cylindrical of revolution around the axis 124 with an identical diameter.
- Each of the end sections 130 is connected to the middle section 131 by a respective intermediate section having the shape of an annular groove 132 of revolution about the axis 124 and symmetrical with respect to a plane parallel to the plane 3 and coinciding with a plane 8 respective so that it will also be designated by the reference numeral 8.
- the intermediate sections 132 are mutually symmetrical with respect to the plane 3.
- each of the grooves 132 has two tapered flanks 133 of revolution around the axis 124 and a cylindrical bottom 134 of revolution around this axis 124, with a diameter less than that of the sections 130 and 131, the two flanks 133 being mutually symmetrical with respect to the respective plane 8, which symmetrically overlaps the respective bottom 134.
- the two sides 133 and the bottom 134 of each groove 132 are positioned and sized, in a manner easily determinable by a person skilled in the art, so that, when the carriage 48 is hooked to the mounting body 4 of the line 1 as illustrated in FIGS.
- roller 128 which has just been described constitutes only a nonlimiting example, and one could choose other means in particular for guiding the yoke 120 which carries it, in the manner of a slide, relative to any form of slide oriented parallel to the axis 119 and carried integrally by the frame 49, this slide being constituted by the slots 127 in the example illustrated.
- the trolley can be used as follows
- the line 1 appears in the state described with reference to FIGS. 1 to 3, that is to say that the or each mounting body 3 retains the two contact wires 7 by the two nozzles 32, 37 by prestressing elastic deflection of the lateral wings 19 in the direction of a separation of their free ends 2 relative to the free end of the central wing 8.
- This state of the line 1 and this configuration of mounting body 3 are illustrated in the figures 4 and 5.
- a first operation consists in installing the carriage 48 on the line 1 so that the lateral rollers 71 of each train 69, in the respective rest position, and each central roller 70 engage respectively in a respective groove 41 and in the groove 31, immediately downstream of a cut made in the wires 7, with reference to a determined longitudinal direction of carriage progression 48 along the line 1, and that the rollers 57 come to rest on the faces 39 of the flanges 41 of the free ends 21 of the lateral wings 19.
- the sleeves 79 corresponding to the two lateral rollers 71 of each set are initially brought together as much as possible, and the roller 128 lowered as much as possible, towards the spacers 53 of the chassis 49, in a manner not illustrated but easily understood by a person skilled in the art .
- the central rollers 70 then ensure the coincidence of the mean longitudinal plane of symmetry of the chassis 49 with that of the line 1, these two planes bearing the same reference numeral 3, as well as the coincidence of the mean plane of each groove 132 with a respective plane 8 and that of the mean plane of each lateral roller 71 of each train 69 with the mean plane 42 of a respective groove 41.
- the roller 128 is then moved away from the wires 7, downwards, by a distance at least equal to the radius of a wire 7 and preferably greater than this radius.
- the carriage 48 by pulling on the carriage 48 in this direction, it is progressively moved over any desired longitudinal dimension of the line 1 in order to bring successively longitudinally localized zones of the lateral wings 19 of the mounting body 4 or of successive mounting bodies 4 to the configuration of maximum elastic deflection, allowing the contact wires 7 to be released, which allows the corresponding longitudinally localized areas to be released successively.
- the mounting body 4 tends to gradually return to a rest configuration behind the carriage 48 with reference to the direction of progression of the latter, but it is avoided that this tendency results in a connection of the wires 7 again by continuing to be applied to them, for example manually, behind the carriage 48 with reference to the direction of progression thereof, sufficient traction, downwards, so that they remain at a level lower than that of the mounting body .
- the carriage 48 is thus made to run through, progressively releasing the wires 7, the entire longitudinal dimension over which it is desired to replace them, until another cut is made on these wires 7.
- each mounting body 4 of the area thus traversed of the line 1 is completely free of wires 7, and the carriage 48 can be brought back, in the direction opposite to the aforementioned direction of progression, to its initial position relative to the zone in question, for example by rolling on the mounting body or bodies 4, which replaces the lateral wings 19 of the mounting body 4 in their configuration of maximum elastic deflection at the upstream end of this zone of the line 1, taking into account the aforementioned direction of progression.
- the lateral rollers 71 successively lead to the configuration of maximum elastic deflection of the longitudinally localized zones of the lateral wings 19 of the successive mounting body or bodies in the direction of progression, and the roller 128 successively places between the spouts 32 and 37 of the mounting body 4 the grooves or grooves 7 of the localized areas of the new wires 7 which also succeed one another in this direction, by means of an elastic bending of the wires 7 immediately in front of the carriage 48 with reference to the direction of progression; behind the carriage 48 with reference to this direction, the areas of the mounting body 4 which the carriage 48 successively leaves tend to return to the rest configuration but are retained in their intermediate configuration of bending prestress by application of the spouts 32 and 37 in the grooves or grooves 11 of the wires 7, which causes the latter to be retained under the conditions described in FIGS. 1 to 3 and the progressive reconstruction of the line 1.
- the sleeves 79 are actuated to bring them back to their rest position, that is to say bringing the lateral rollers 71 closer to each set 69 while keeping the roller 128 in position, which brings the lateral wings of the mounting body 4, also in this extreme zone, to their configuration of elastic bending preload in which they retain the wires 7 between the spouts 32 and 37.
- the carriage 48 can be detached from the mounting body 4, that is to say from the line 1 thus reconstituted. It will be observed that the method of winding the wires 7 of a line 1 can also be used for the initial assembly of such a line, after the mounting bodies 4 have been hung on the roof of the tunnel by the individual elements. support and their splicing.
