The installation and removal of sections and mounted track devices such as, for example, crossings and deviations is currently practiced almost generally in preference to the old practice of assembly and disassembly in situ, with the main aim of disrupt rail traffic for as little time as possible.

The complex structure of the switches and their long length mean that the assembly and disassembly of their constituent elements such as straight and curved rails, needles and switch hearts and counter-rails on the sleepers and on the very places of their use would not be compatible with the rates of rail traffic, due to the slowness of these operations.

The fitting of a new switchgear intended for the replacement of an old one is therefore carried out thereby in a chosen location that is sufficiently clear and as close as possible to the replacement location, next to or even on a secondary railway track which can there drive and which will be used for the transportation of this new device once mounted.

The old device to be replaced is also removed, also mounted, for the same reason of sparing rail traffic, and evacuated by rail.

Before the installation of the new switchgear in place of the old one, the ballast is treated and in particular flattened by so-called adjustment operations which are carried out by other machines suitable for these works.

There are known machines of the aforementioned kind which have been created to ensure both the removal and the evacuation of a section or of an old track device and the laying of a new section or of a new device and which are able to move both on the track and on the ballast as well as to lift, move laterally and carry such sections or devices.

In a known machine of this kind, described in the German published patent application No. 2313055, the carrying structure is articulated by its ends and along vertical axes on two vehicles each equipped with two axles capable of running on the track and two tracks suitable for running on the ballast usable as an alternative. On this machine, the carrying structure comprises a lifting means constituted by an extendable winching arm mounted to rotate 360 ° in a horizontal plane on a carriage mounted mobile along this structure, and the means allowing the gripping of a section or of a track device stored on the ground next to the track are constituted by retractable lateral supports associated with each vehicle and intended to ensure the lateral stability of the machine during the lifting of these loads.

In another known machine of the same kind, described in German patent N ° 2928152, the carrying structure is not articulated but simply fixed by its ends on two vehicles having mixed displacement means made up of tracks and bogies articulated according to vertical axes on the chassis of said vehicles. On this machine, the lifting means are constituted by winches mounted in a manner known per se mobile and adjustable transversely to the track and the means allowing the gripping of a section or of a track device mounted stored on the ground next to of the track are constituted by its own tracks which are provided for this purpose pivotable by 90 ° along a vertical axis to allow lateral movement of the whole machine up above this section or this track device.

These known machines have the great advantage of only using and cluttering a single track during installation and removal work, the same comprising the section or the track apparatus to be replaced. This is thanks to the fact that these machines are capable of spanning the length of the working area and of grasping, lifting or even laying a section or a track device between their two end vehicles, as well as traveling with such loads. on the same track.

However, the length of the supporting structure of these machines included between their end vehicles is necessarily limited by the obligation to register this structure in the curves of the track inside the transverse safety gauge in force.

Indeed, in the curves, the middle part of the supporting structure is offset towards the inside of the curve by a value corresponding to the deflection of the arc produced by the curvature of the longitudinal axis of the track between the articulations of the extreme supports of the machine. During long distance journeys, this offset must not have the effect of making the bearing structure exceed the limits of the above-mentioned gauge in order to avoid any risk of encountering lateral obstacles which may exist outside these limits, in particular that of a convoy traveling on an adjacent parallel track.

This is a drawback for these machines because they cannot therefore ensure the removal and installation in a single assembled length of the whole of certain track apparatus of the high speed main lines which are currently developing. Examples of these devices include the deviations whose structures extend over lengths which can exceed 60 m because of their small radius of curvature necessarily limited by the high speeds of movement of the convoys, ie substantially double the length of the devices. track that can be installed or removed with these machines.

There is a well-known railway installation of a completely different kind capable of ensuring the installation and removal of these long track devices and which is described in French patent N ° 1540039, but this installation is complex compared to the machines. above and requires a considerable supplement of operations not directly related to those of installation and removal proper. This installation indeed comprises a plurality of removable elements such as gantries, carriages and lifting devices mounted mobile by sliding along an articulated beam and which must be put in place, move and remove successively as and when the progress of the work while the beam itself is kept raised with fixed support on the work area. The track device to be placed or deposited is also transported on the track independently of the articulated beam in front or behind the latter and on trolleys, and its transfer from the trolleys to the beam or vice versa is done through gantries. In addition, this installation does not provide by its own means the capture and transfer under the beam of a track device which has been previously mounted next to the track on which it runs.

The object of the invention is to offer the possibility of at least doubling the range of machines of the kind mentioned at the beginning of the presentation, in order to allow them to ensure the installation and removal of long track devices while retaining their advantages, compared to the aforementioned installation, of their simplicity of use as well as of structure and of their ability to grasp or place a switchgear next to the track to be treated by their own means.

To this end, the machine according to the invention is characterized in that its supporting structure is in at least two parts connected together by a universal joint, in that this supporting structure comprises an intermediate support disposed in the region of said seal and having on the one hand an intermediate vehicle with two individually motorized side tracks mounted movable and individually adjustable both in height and in the transverse direction of the track on a frame articulated along a vertical axis on one of the two parts of the supporting structure, and on the other hand an intermediate bogie mounted under the lower cross member of a vertical frame transverse to the track, the upper cross member of which is connected to one of the two parts of the supporting structure, the two vertical uprights of which are separated from each other at least a minimum distance corresponding to the transverse space occupied by the rails of the switchgear directly above said frame and the l a lower crosspiece linked to the intermediate bogie is removable from the space between the plumbs of the two vertical uprights at least by separation of one of its two ends of the frame and pivoting of the other and / or by separation of its two ends said frame.

In this way, the combination of the effects arising from the design of the supporting structure and the intermediate support makes it possible, simply and surprisingly, to place and remove devices

of track mounted with a length greater than double those likely to be laid or deposited with known machines of the kind mentioned at the start of the presentation, while retaining their advantages.

Indeed, thanks to the design of the intermediate support which leaves free the space between the two side tracks of the intermediate vehicle and which allows to fully release the space between the two uprights of the frame carrying the intermediate bogie, it is possible to provide these sufficient spaces, in their largest widths, to allow the entry, installation or removal between these tracks and these amounts and over the entire extent of the track area between the two end vehicles a section or a track device mounted with a total length corresponding to the span of the supporting structure between these two vehicles. In their minimum spacing, the uprights of the frame are outside the rails of the switchgear and it can be lifted between them after simply loosening and slightly apart the two crosspieces located one in front and the other behind their plumb. In addition, the range of the supporting structure can here exceed twice that of the known machines in question thanks to the design of this supporting structure in at least two parts hinged together, the length of each of which can equal that of these machines without engaging the transverse safety gauge in the curves and without losing on this span the space occupied by the intermediate support.

In one embodiment of the invention, the two uprights of the frame are mounted to be displaceable and adjustable in spacing beyond their minimum spacing in order to be able to offset them outside the mentioned crosspieces and thus avoid loosening and the displacement of the latter.

The invention will be better understood with the aid of the description which follows and other possibilities as well as their advantages will emerge from the latter.

The machine, represented as a whole fig. 1 and 2, consists of a supporting structure 1 extended in the direction and above a railroad track 2, designed in two parts 1A and 1B connected together by a universal joint 3 and comprising a plurality of devices lifting 4 movable and adjustable in the transverse direction of the track, two end vehicles 5 and 6 separated by a distance greater than the length of a mounted track device 7 shown here suspended from the lifting devices 4, and a support intermediate 8 disposed near the universal joint 3, here on the part 1A of the supporting structure.

The two parts 1A and 1B of the supporting structure 1 are here two hollow beams of rectangular sections.

Each of the two end vehicles 5 and 6 is identical to the other and comprises a motorized bogie 9 and two side tracks 10 usable alternatively on track 2 and on the ballast.

On each of these two vehicles, including the one on the left marked 5 is detailed in FIGS. 3, 4 and 5, the bogie 9 and the tracks 10 are mounted on a chassis 11 articulated along a vertical axis X to the corresponding part of the bearing structure by means of a mixed support 12 comprising a clamp 13 and two pads lateral 14 bearing on two corresponding pads carried by this chassis.

The bogie 9 is here constituted by two axles 15 movable and adjustable in height on the chassis 11 by means of two oscillating supports 16 which carry them and which are articulated on horizontal pins 17 carried by this chassis. The height position of each axle 15 relative to the chassis 11 is ensured by a hydraulic cylinder 18 and each axle 15 is motorized by a hydraulic motor 19 integrated into each oscillating support 16.

The chassis 11 is composed of two vertical parallel flanges 20 connected by two upper crossbars 21 on which the jacks 18 are supported and by two lower crossbars 22, tabular and of square section, in which are slidably mounted transversely to the track two arms side 23, also of square section. At the outer end of each of these two arms is fixed a vertical tubular upright 24, of rectangular section, in which is slidably mounted a vertical column 25, also of rectangular section. The lower part of each column 25 comprises a horizontal pin 26 on which one of the two tracks 10 is articulated.

The transverse movement of each lateral arm 23 is controlled by a hydraulic cylinder 27 and the vertical movement of each column 25 is controlled by a telescopic hydraulic cylinder 28.

Each track 10 is motorized by an integrated hydraulic motor 29.

This design of each of the two end vehicles 5 and 6 makes it possible, by the combination of the lowering of the axles, and the raising and bringing together of the tracks, to inscribe the latter in the transverse gauge of the track during travel. of the machine on the track using its motorized axles, as in the configuration shown in fig. 1, as well as fig. 3. By the reverse operations of raising the axles and lowering and spreading the tracks, this design also makes it possible to span the track beyond its total length, as in the configuration shown in fig. 2, as well as in FIGS. 4 and 5, as well as clearing as much as possible the space under the chassis 11 of this vehicle.

The intermediate support 8 has on the one hand an intermediate vehicle 30 with two side tracks 10 motorized individually displaceable and individually adjustable both in height and in the transverse direction of the track, identical to those of the end vehicles 5 and 6 , and on the other hand an intermediate bogie 31, this vehicle and this intermediate bogie being mounted independently of one another on the same part 1A of the bearing structure, and the bogie 31 being the closest to the articulation universal joint 3.

The intermediate tracked vehicle, detailed in fig. 8 and 9 in the configuration corresponding to that of FIG. 2, comprises a frame 32 articulated along a vertical axis X on the part 1A of the bearing structure here also by means of a mixed support 33 com5

carrying a toad 13 and two lateral pads 14 bearing on two corresponding pads carried by this chassis.

The two tracks 10 are mounted on the chassis 32 of this intermediate vehicle in the same way as on the end vehicles 5 and 6, and the similar elements of this assembly therefore bear the same references so that we can refer to the same description, the chassis 32 being constituted for its part by the two crossbeams 22 of this assembly connected to one another.

The intermediate bogie 31, detailed in fig. 6 and 7 in the configuration corresponding to that of FIG. 1, consists of two axles 34 carried by a rigid frame 35 articulated along a vertical axis X on the lower cross member 36 of a vertical frame 37 transverse to the track, the upper cross member 38 of which is connected to the part 1A of the supporting structure by means of a device 39 for adjusting its height position relative to this part, and whose vertical uprights 40 are mounted displaceable and adjustable in spacing on this frame.

The device 39 connecting the upper cross member 38 of the frame to the part 1A of the supporting structure is made up of two vertical columns 41 fixed to this cross member and two tabular vertical slides 42 fixed to said part 1A and in which the two columns are slidably mounted 41. The adjustment of the height position of this crosspiece 38 relative to the part 1A is obtained by means of two hydraulic cylinders 43 'acting in parallel on the translation of the columns 41 in the slides 42.

The lower cross member 36 and the upper cross member 38 of the frame 37 are tabular and include telescopic side extensions 43 connected by the uprights 40 and whose displacement in translation, making it possible to adjust the spacing of these two uprights, is controlled by two hydraulic cylinders 44, visible only in fig. 6, braced each between the upper cross member 38 and one of its two telescopic extensions 43, each upright 40 can thus be moved independently of the other.

The two uprights 40 of the frame 37 are pivotally mounted along their vertical axis at the end of the two telescopic extensions 43 of the upper cross member 38 by a connection 45 of the shaft-bearing type and the lower cross member 36 carrying the intermediate bogie 31 is connected by its two extensions 43 to the two uprights 40 by a removable link. This removable connection here comprises two parallel pins 46 integral with each upright 40 engaged in two corresponding sleeves 47 of each extension 43 and two bars 48 connecting each extension with each upright, these two bars being fixed to these two elements by means of removable pins 49.

This design of the intermediate bogie 31 makes it possible to adjust the spacing of the uprights 40 of the frame 37 which supports it as a function of the width of the track device 7 at its level, and to bring these uprights inside the transverse gauge of the track in the folded position. This design also allows the erasure of the lower cross member 36 and the bogie 31 of the space between the plumbs of the two uprights 40, in order to allow the installation or the removal of a track device between these two uprights. This erasure can be done here in two different modes which will be described later in the paragraphs relating to the operation of the machine.

The height travel and the transverse travel of each track 10 of the end vehicles 5 and 6 and of the intermediate vehicle 30 are provided sufficient, in this embodiment given as an example, to allow transport over long distances of the machine on freight platform cars harnessed together and towed by a locomotive. This possibility is illustrated in Figs. 11 and 12, on which is shown a platform wagon 50 bearing on track 2. To do this, the machine being previously parked and bearing on track 2 by its three bogies, the tracks 10 of its three vehicles are first of all moved aside then placed on the ballast on both sides of the track and finally lowered to raise the two parts 1A and 1B of the supporting structure and the three bogies to a sufficient height to allow the passage of the wagons- platforms 50 under these bogies and between lesdi-your tracks, in a configuration corresponding to that shown on the right part of FIG. 11. Then the tracks 10 are lifted and brought inward, in a configuration corresponding to that shown on the left of this same fig. 11. Simultaneously with these operations and when the machine is resting on its tracks, the intermediate bogie 31 is raised by means of the device 39 for lifting the frame 37 which carries it and the lateral uprights 40 of this frame are retracted towards the interior, in the configuration shown in fig. 12. At this time, all the elements of the machine are inscribed inside the transverse gauge of the track marked G in these two figures and its supports are immobilized by wedging at will on the platform wagons 50, that these supports are constituted by the bogies, by the tracks or by additional removable supports according to the distribution of the loads on these wagons.

In this configuration shown in fig. 12, the intermediate bogie 31 is immobilized in the transverse direction of the track by abutment of the lower cross member 36 between the two connecting bars 48. But it is also possible to provide a different means, for example using pins " to cross "removable directly connecting the bottom cross 36 to its two extensions 43.

This possibility of transporting the machine on goods platform wagons does not exclude its autonomous movement and loaded by means of hydraulic motors driving the axles of the bogies of the end vehicles 5 and 6, as for example from the place of installation of a switchgear, generally close to its place of installation, up to the latter, in the configuration shown in fig. 1. However, this possibility of transporting the machine on wagons is advantageous, because it avoids the use of bogies with couplings, brakes and drive motors of greater power, prescribed for high-speed walking. walk long distances.

In the case of autonomous movement and under load of the machine according to the configuration shown in fig. 1, it may be advantageous, however without being essential, to provide a possibility of lateral displacement of the bogie 31 of the intermediate support relative to the bearing structure, for example in order to avoid an out of gauge obstacle, of a either side of the track. This can be done very simply, for example by connecting the lower cross-member 36 of the frame (FIGS. 6 and 7) to one of its two extensions 43 using a hydraulic cylinder for adjusting their relative translation,

as the jacks 44 do between the upper cross member 38 and its two extensions 43.

Each lifting device 4 installed on the supporting structure of the machine, detailed in fig. 13, 14 and 15, comprises a fixed cross member 51 rigidly fixed to this supporting structure 1A-1B, two lateral extensions 52 of this cross member, a winching carriage 53 mounted movably on this cross member and its extensions and equipped with a motorized winch 54 , and a beam 55 with hooks with adjustable rails 56 attached to the winch ropes.

Each extension 52 is carried by a console 57 articulated along a vertical axis on two bearings 65 'fixed on a side wall of the supporting structure 1A-1B so as to be able to retract by pivoting around this axis against this wall, as shown on the left side of fig. 13, as well as on the upper part of FIG. 15. This pivoting is obtained and controlled by means of a hydraulic cylinder 58 bearing at one end on a lateral arm

59 fixed to the side wall of the supporting structure 1A-1B and by the other end on a deported pivot 60 carried by a lever 61 fixed to the console 57.

The pivoting movement of the extension 52 obtained by the action of the jack 58 is communicated to all of the lifting devices 4 installed on the same side of each part 1A and 1B of the bearing structure by connecting rods 62, visible fig. 15, as well as fig. 1 and 2, each connected by their two ends to the pivots

60 of the levers 61 of two consecutive extensions 52. In this way a single cylinder is sufficient to retract or exit simultaneously all the

extensions 52 located on the same side of each part 1A and 1B of the supporting structure.

Each extension 52 of each lifting device 4 is shown here equipped with a retractable lateral support 63 articulated at the end of this extension. This lateral support consists of four distinct elements, the kinematics of which are in a vertical plane, constituted by a triangular oscillating support 64 articulated by a first vertex 65 at the end of the extension 52, a first hydraulic actuator 66 for controlling of the oscillation of the support 64 connected to a second apex 67 of this support, a support pad 68 and a second hydraulic cylinder 69 carrying said pad at the end of the piston rod and whose body is articulated at the third apex 70 of the oscillating support 64.

This retractable lateral support 63 is put into service, as shown in FIG. 13, by extension until the end of travel of the first jack 66, as well as by extension of the second jack 69 until the ground 71 meets the support pad 68. Its retraction is obtained by retraction until the end of stroke of these two cylinders, as shown in fig. 14.

This particular design of retractable lateral support has the advantage of associating a minimum of bulk in the retracted position with a maximum of extension in height as well as lateral in the service position. This effect is obtained thanks to the fact that its structure combined with its kinematics makes it possible both to lower and move away from the bearing structure the connection point 70 of the jack 69 carrying the pad 68 when it is put into service, and vice vice versa to raise and bring this point closer to the retracted position.

Thus produced, this lifting device allows, as shown in fig. 13, the entry and transfer under the bearing structure 1A-1B of a track device 7 which has been previously mounted and stored on the ground 71 next to track 2 on which the machine circulates, without causing breakage of balance of the latter, thanks to the retractable lateral support 63, and in a simple and reliable manner not requiring lateral movement of the machine.

However, the gripping of a track apparatus stored next to the track can be done without the aid of lateral supports of any kind by using the independent lateral displacement faculty of each of the tracks 10 of the machine. This is obtained, after having put the machine in tracked stasis, by successive lateral displacements of each of them and in turn, while the balance is ensured by the others, until the bearing structure overhangs this device. channel, the return to load on channel 2 then taking place in the same way in the other direction. During these lateral displacements and each time a caterpillar is lifted before its lateral displacement, the torsional stress of the bearing structure is sometimes collected by it alone sometimes by association with the universal joint 3 according to the displaced crawler. Therefore, when this mode of entry of a switchgear is chosen, the universal joint 3 must be provided with sufficient strength to withstand this constraint.

The fitting of a track device 7 intended for the replacement of an old one is done, using the machine which has just been described, as follows:

The machine is brought into its autonomous transport configuration shown in fig. 1, until the cut of track 2 preceding the ballast platform 72 which has been previously leveled and which must receive this track apparatus 7.

The vehicle 5 located closest to this platform 72 is put on tracks and raised, as in the configuration shown in FIG. 4 and 5, and the machine is advanced on this platform,

according to arrow A, using the motorized tracks of this vehicle and the motorized axles of the other end vehicle 6, until the arrival of the intermediate vehicle 30 above the platform 72, the intermediate bogie 31 still being supported on track 2. The tracks 10 of this intermediate vehicle are then moved apart and supported on the ballast, in the configuration shown in FIG. 8 and 9, and the lower cross-member 36 of the frame 37 carrying the intermediate bogie 31 is detached from the uprights of this frame by dismantling the connecting bars 48 (fig. 7) and lifting this frame until the pins 46 of these amounts are released from the sleeves 47 of the extensions of this lower cross member 36. After this operation the machine is again advanced along arrow A, the bogie 31 abandoned on the spot, until the last vehicle 6 arrives against it. At this time this vehicle 6 is in turn placed on its tracks and then raised enough to be able to step over this bogie 31 and, finally, the machine is again advanced in the same direction and entirely up above the platform of ballast 72, in the configuration shown in fig. 2, the bogie 31 having remained behind the machine on track 2. In this configuration, the intermediate support 8 is completely clear of any obstacle in its central part between the tracks 10 and the uprights of the frame 37, in the configuration shown in fig. 10, and the track device 7 can be lowered and placed in its place in one piece. The precision of this installation is obtained by the combined play of the tracks 10 of the three vehicles, which allow longitudinal and lateral movements of the bearing structure, and lifting devices 4 which allow lateral movements of the track device 7 relative to to this supporting structure.

Once the track unit 7 has been placed, the machine is put back on track 2 by reverse maneuvers to those which have just been described. The removal of a track device is done in much the same way, as regards the positioning of the machine on the area occupied by the old device to be deposited, except that the machine can be brought up above this device on its three bogies, the lifting of these by means of the tracks 10 and the evacuation of the intermediate bogie 31 can be done on site.

The advantage of this operational mode resides in the fact that the erasure of the intermediate bogie under the bearing structure does not in any way engage the parallel traffic lanes, when these exist, which makes it possible to operate in complete safety without hindering traffic on these tracks.

When, on the other hand, the lateral space is free from any other path on one side or the other of the machine, another operational mode can be applied in which the intermediate bogie 31 is simply retracted by pivoting towards the outside of the track, on the free side, instead of being detached, spanned and left, then then resumed on the track. This can be done by separating the lower cross member 36 from the frame 37 carrying this bogie only on one side of an upright 40 of this frame and by pivoting this cross member which remains integral with the other upright, on the free side, around of the joint 45 of the latter (fig. 7), for example manually.

This second operational mode is advantageous, when it can be applied, because it avoids the maneuvers inherent in abandoning and resuming the intermediate bogie 31 on the track.

The connection between the lower cross member of the frame and its uprights can obviously be designed differently and the pivoting of this cross member, according to the second operational mode, can be motorized.

The variant partially shown in FIG. 16, 17 and 18 is given to illustrate this possibility.

In this variant, for the understanding of which reference will also be made to FIGS. 6 and 7, each extension 43 of the lower cross member 36 of the frame is fixed to an upright 40 by a simple vertical locking screw 73 engaged in an axial threaded hole of a pin 74 with shoulder 75 secured to each upright 40 engaged in a sleeve 76 integral with each of these extensions. The shaft 77 of the rotary link 45 of each upright 40 engaged in the bearing of an extension 43 of the upper cross member 38 has, at the outlet of this bearing, a horizontal lever 78 actuated by a hydraulic jack 79 installed in abutment on a console horizontal 80 oriented in the longitudinal direction of the track and rigidly fixed to the extension 43 in question.

After loosening and removing the screw 73 connecting an extension of the cross-member 36 to the corresponding upright 40, the rotation of the other upright according to a chosen angle R of between 90 ° and 180 ° makes it possible to rotate the cross-member 36 carrying the bogie 31 sufficient to clear the space between the two uprights 40 of the frame 37.

The second variant shown in fig. 19 and 20 is a simplified and economical construction of the frame carrying the intermediate bogie 31 in which the two uprights 40 are mounted at a fixed distance directly on the upper cross member 38 itself rigidly fixed to the supporting structure 1 A, these two uprights 40 and this crosspiece 38 forming a single piece in the form of an inverted U.

The spacing of the two uprights 40 here corresponds to the transverse space occupied by the rails of the track apparatus 7 above the frame. It is in fact advantageously found that, for the great majority of long track apparatus, this space, at the level considered, is less than the width of the safety gauge of the track of a value sufficient to allow passage of the two uprights 40 on the outside of these rails, within the limits of this template.

The lower cross member 36 of the frame is here in one piece made integral with the two uprights 40 by two removable end connections each constituted by a conical pin 81 secured to an upright 40 engaged in a conical sleeve 82 secured to one end of the lower cross-member 36, these two elements being locked one inside the other by a screw 83 engaged in the spindle 81 and bearing under the cross-member 36.

The bogie 31 is here pivotally mounted on a clamp 84 secured to a support 85 mounted movable and adjustable in the transverse direction of the track along the lower cross member 36 of the frame according to a limited stroke defined by the avoidance needs d '' possible lateral obstacles out of shape during autonomous transport journeys on track of the device in high-footed mode. However, this mobility is not essential and the clamp 84 can also be mounted on a fixed post on the cross-member 36.

In the laden transport configuration on goods platform wagons, the bogie 31 is immobilized on the cross member 36 by any means, such as for example a pin 86 for immobilizing the support 85 of the clamp on said cross member 36, or alternatively by means of a jack for connecting this cross member to said bushing and which, at the same time, can serve as a means of adjusting the relative position of these two elements.

In this second variant, the bogie 31 can be removed and abandoned on the track by detaching the cross-member 36 from the uprights 40. To do this, after loosening and removing the screws 83, the bearing structure is lifted using the tracks 10 of the intermediate vehicle 30 until the pins 81 are cleared above the cross-member 36.

Before entering and lifting the track device 7, the two crosspieces of this device located directly above the two uprights 40, here marked with a cross fig. 19, are loosened and separated by an amount sufficient to allow the passage between them of these two amounts.

It is possible if deemed necessary to provide for the retraction of the two uprights 40 by pivoting upwards using jacks; in this case, these two uprights are pivotally mounted in a vertical plane transverse to the track at the end of the upper cross-member 38.

It is also possible to provide the mounting of the two uprights 40 at the end of the upper cross member 38, as well as their connection with the lower cross member 36 in the same manner as in the embodiment shown in FIG. 6 and 7, in order to also allow the removal of the bogie 31 by rotation about the vertical axis of an upright 40 towards the outside of the track.

The upper cross member 38 of the frame can be mounted mobile and adjustable in height relative to the part 1A of the supporting structure in the same manner as in the embodiment shown in FIG. 6 and 7, in order to avoid the use of the tracks 10 of the intermediate vehicle 30 for lifting said bearing structure during the removal of the bogie 31.

Within the strict framework of the invention, other variants, not shown, may be applied.

Thus, the machine can be designed autonomous for long journeys by equipping its end vehicles with bogies, couplers,

brakes and motors prescribed for up-walking, in which case the height travel of the tracks 10 of all its vehicles may be reduced and limited to the useful for the maneuvers of laying and removal, compared to the travel required to load the machine onto a train of freight platform wagons.

The mounting of the axles 15 of the bogies 9 of the two end vehicles allowing their displacement in height relative to the chassis 11 which carries them is not essential when large differences in position between these axles and the tracks 10 of these vehicles are not not sought, as for example when the machine is used for autonomous movements only over very short distances and when its long-distance transport is done on a train of low-platform wagons.

One of the two end vehicles may have only the bogie, excluding the tracks 10. In this case, the removal and installation are done in one direction and the machine must necessarily be equipped with support devices lateral in the kind of that described or of another known kind, associated or not with lifting devices, to allow the gripping and lifting of a track apparatus stored next to the track without unbalancing the machine, the displacement lateral of the latter by its tracks is no longer possible. Still in this same case, it should be noted that the abandonment of the intermediate bogie 31 on the track is always possible insofar as the track device or the section transported is shorter than the distance separating the two end vehicles d 'a length corresponding to that of this bogie, because it can no longer be stepped over to free it from under the machine. However, for a device or a section of length corresponding to the distance separating the two end vehicles, the pivoting of this intermediate bogie 31 towards the outside of the track remains possible to clear the space between the uprights of the frame which door. In the latter case, it is possible and advantageous, after horizontal pivoting of the cross-member and of the bogie in question, to provide for the possibility of straightening it in a vertical plane parallel to the track in order to limit its lateral dimensions by the addition of a second articulation, preferably motorized using a jack and designed in this direction.

It is therefore possible to envisage a total or only partial separation of the lower cross member from the frame carrying the intermediate bogie 31, without or with pivoting of this cross member according to the option chosen, or else as in the embodiment described, reserve all possibilities in order to be able to choose the fastest and most suitable maneuver for the environment.

The device 39 for moving and adjusting the height of the frame 37 supporting the intermediate bogie 31 relative to the bearing structure is not essential for lifting this frame during the abandonment maneuver of this bogie, because this lifting can be done by means of the tracks 10 of the intermediate vehicle 30. However, this device is advantageous when it is desired to avoid the additional energy necessary for lifting the bearing structure, during this maneuver by the tracks in question.

The two elements of the intermediate support 8, the tracked vehicle 30 and the bogie 31, can either be grouped on one of the two parts of the bearing structure as shown in the example given, or one on the one of these two pieces and the other on the other piece. In the example given, the grouping of these two elements on the same part, however, provides the possibility of using this part independently, without the addition of the other, when its length between supports is sufficient for laying or removal of a small section or track device. In such an eventuality, the universal joint 3 is provided for removable.

Finally, the design of the machine according to the invention makes it possible to envisage the transport, the installation and the removal of railway equipment of very long lengths, such as for example mounted sections, by increasing the number of articulated parts which make up the bearing structure. , the latter in this case also having an intermediate support 8 close to each of its cardan joint joints 3.
