Definitions
- the invention relates to mobile intervention installations on railways, and in particular to track maintenance and repair installations.
- Portable tools are relatively inconvenient to use, since the concept of portability covers a wide variety of tools and machines, some of which are bulky and not as light as would be desirable, and this is precisely the case in the railway sector. ; a typical example is that of machines for grinding rail joints, which can only achieve a result in accordance with standards if their length is of the order of a meter, and whose weight is necessarily important given the nature of the tool itself.
- Trolley installations are generally specialized by type of intervention, and the maintenance of tracks on a given site requires the existence on this site of quite a large number of them.
- their weight hundredseveral hundred kilograms makes them difficult to transport from their storage location to the track, this drawback being appreciable in the case of metropolitan railways, when they have to pass through corridors and stairs designed to be used by the public during normal operating hours of the network, and also when it is necessary to transfer them from a platform to the track and vice versa.
- the object of the invention is to remedy these drawbacks, and for this purpose consists of a mobile installation for the maintenance and repair of railways, of the type comprising a trolley provided with intervention equipment on the track and comprising running gear, operating in association with drive components, and control equipment, installation characterized in that it consists of several modules which are removably secured to form a line of carriages fitted with rolling members, comprising at least an intervention trolley on the track adapted to carry at least one intervention apparatus, and a control trolley comprising an apparatus for controlling the intervention apparatus, and in that the intervention trolley comprises a chassis having , seen from above, an H shape consisting of a central body and branches of substantially equal lengths extending substantially perpendicularly on either side re of this body at the ends thereof to determine on either side of the body two notches each extending between the branches being opposite one and the same side thereof, and the branches comprise removable securing means suitable for securing an intervention apparatus to each pair of branches constituted by two branches facing each other on the same side of the body.
- a small number of trolleys is sufficient to be able to carry out a wide variety of interventions, since the trolleys are not specialized and can be equipped on demand with the desired intervention apparatus. Also, the installation can be easily transported, since on the one hand the modules are removably secured and thus can be transported separately, and on the other hand the intervention apparatuses are themselves removable with respect to the intervention trolley.
- each of the carriages can be constituted by the association of several modules, namely a module constituted by an H-shaped frame and two modules constituted respectively by two bearing assemblies provided with rolling members, the H-shaped chassis module being disposed between and removably secured to these two rolling members.
- the immediately following intervention carriages can have a common bearing assembly, which reduces the material costs.
- the removability of the bearing assemblies relative to the chassis makes it possible to further reduce the weight of the elements to be transported.
- these may include retractable transverse motion undercarriages, and boxes extending transversely and telescopically extendable, fitted with jacks mounted pivoting about a horizontal axis and the rod of which comprises a clamp capable of enclosing the rails.
- FIG. 1 is a schematic side view of a first embodiment of an intervention trolley forming part of an installation according to the invention
- FIG. 2 is a schematic top view of the carriage of FIG. 1,
- FIG. 3 is a schematic side view of a second embodiment of an intervention trolley forming part of an installation according to the invention
- FIG. 4 is a schematic top view of the carriage of FIG. 3,
- FIG. 5 is an end view of the carriage of FIG. 3 during a phase of its transfer from a quay to a track
- FIG. 6 is an end view of the carriage of Figure 3 during a later phase of its transfer from a platform to a track.
- the mobile installation one of the components of which is shown in the figures, is intended for the maintenance and repair of railways such as those of a metropolitan rail network.
- this modular installation consists of modules which are removably secured to form a line of carriages comprising at least one intervention trolley and one control trolley.
- the installation comprises one or more intervention carts 1 such as that shown in these figures and a control carriage.
- the intervention trolley 1 is adapted to removably carry intervention apparatus 2, themselves in modular form, interchangeable, each capable of carrying out a specific intervention or task, the tasks likely to be performed being very varied. .
- intervention apparatus 2 themselves in modular form, interchangeable, each capable of carrying out a specific intervention or task, the tasks likely to be performed being very varied.
- the control trolley (not shown in the drawings) carries control apparatus for intervention apparatus, possibly an electric or thermal engine apparatus, and a cabin for an operator whose role is to govern the control apparatus and the engine equipment.
- the intervention carriages like the control trolley are constituted in the form of modules provided with rolling members 3 constituted by cheek wheels; here, the carriages being of relatively small weight and dimensions (of the order of a meter), two sets of wheels respectively front and rear each carrying two wheels respectively left and right, are sufficient.
- the intervention carriages have, seen from above when their wheels 3 rest on a horizontal ground, an H shape which is that of their chassis 4; the central body of the H is constituted by a spar 41 whose direction then extends horizontally in the vertical plane equidistant from the left and right wheels 3; this spar 41 carries at each of its two ends, two branches 42 extending laterally perpendicularly on either side of it, • the four branches 42, here substantially equal, therefore determine two approximately rectangular notches 43 on either side other from the central body 41; the branches being made vis-à-vis the same side of the body to determine the indentations, include removable securing means of intervention apparatus 2, themselves provided with securing means cooperating with them; here, the removable securing means carried by the branches of the chassis are constituted by slides 44 intended to receive rollers 21 carried by the faces of the intervention apparatus intended to come opposite the faces of the branches 42 of the chassis being vis-à-vis the same side of the body; of course, the nature of the guide tracks thus defined between the faces of the branches 42 of
- the slides 44 must be able be moved and to this end are secured to movable members of cylinders (hydraulic, electric or pneumatic) not shown, controlled by the control equipment carried by the control carriage.
- the intervention trolley therefore constitutes a rigid assembly in one piece, and, under the branches 42 of the chassis, are fixed yokes 45 carrying an axle or the axes of the wheels of the trolley.
- One or more stiffening arches 46 extending longitudinally above the carriage can be fixed on it, for example two arches can be fixed to the branches of the chassis respectively on either side of the spar. To these arches can be attached a transverse beam 47 facilitating the gripping of the carriage by a lifting device.
- Branches 42 of the chassis also carry boxes containing an apparatus 48 for actuating intervention apparatus; the actuating apparatuses 48 are electrically connected to the control apparatus carried by the control module, and electrically and possibly pneumatically or / and hydraulically to the intervention apparatus 2 which they actuate.
- control carriage of this first embodiment comprises an apparatus for controlling the intervention apparatuses 2, acting on them by means of the actuation apparatuses 48 carried by the intervention carts 1.
- This control apparatus is computer controlled. Preferably, it is connected to each actuating device by a two-wire connection.
- the control carriage also here includes an engine switchgear mechanically connected to its bearing to drive them in rotation. Thanks to the fact that the chassis supporting the motor equipment is not rigidly linked to that of the intervention carriages 1, but by an articulated mechanical connection, the vibrations of the motor equipment are not transmitted to the intervention equipment.
- the control equipment is housed in a cabin intended for the operator of the installation.
- this cabin is connected to the chassis of the control carriage with the interposition of elastic seals in order to avoid parasitic noise originating from the vibrations of this chassis; also, the interior of the cabin can be kept under slight overpressure so that dust, chips, filings, droplets resulting from high-pressure cleaning, etc. cannot penetrate it and thus inconvenience the operator and disturb the operation of the control apparatus, and the elastic seals then also play the role of seals.
- the control trolley can also carry power supply equipment, a generator and / or a storage battery.
- FIGS. 3 to 6 in which the same elements as those in FIGS. 1 and 2 bear the same numerical references, an additional step is taken in the modularity of the intervention carts.
- the carriages are also produced with a chassis 4 in H, and the intervention equipment 2 are still arranged in the lateral notches 43 already mentioned, but the dimension of the branches 42 of the chassis in the longitudinal direction of the carriage is smaller , due in particular to the fact that the yokes 45 carrying the shafts of the wheels are not fixed to them.
- each chassis 4 two motor modules 5 are arranged in a removable manner and on the other side of the chassis 4 respectively at the front and at the rear thereof, constituted by a cross member under which the yokes 45 are fixed, carrying the axles or the axes of the rolling members 3, and supporting an engine switchgear 50 mechanically connected to the running gear (here cheek wheels) to drive them in rotation.
- the chassis being, as in the first embodiment, a rigid assembly to which the rolling members are attached, here the chassis 4 is articulated to the motor modules 5 by ball joints 6 or with cardan joint or the like, and thus is suspended between two motor modules; here again, the intervention apparatuses 2 therefore do not undergo the vibrations due to the motor apparatuses.
- the engine modules can carry, in addition to the actuation apparatuses 48, and the engine apparatuses 50, a supply apparatus 51 such as a generator set and / or accumulator batteries for supplying the engine apparatus, as well as accessory storage boxes; alternatively, this apparatus and / or these boxes can be carried by the control trolley.
- a supply apparatus 51 such as a generator set and / or accumulator batteries for supplying the engine apparatus, as well as accessory storage boxes; alternatively, this apparatus and / or these boxes can be carried by the control trolley.
- control carriage is devoid of motor equipment since motor equipment 50 is integrated into separate modules 5, and where each intervention chassis 4 is disposed between two motor modules, it is possible, in the case where several intervention chassis must be associated, to connect them by a single motor module 5 disposed between them; in other words, the successive intervention carriages have in common in particular the rolling members 3 interposed between them and their motor equipment 50.
- the motor equipment 50 must all be synchronized, and can for this purpose advantageously include a motor known in the art under the name of "brushless motor".
- the intervention chassis 4 are ' suspended between two motor modules 5 by articulated securing means 6, they have a certain number of degrees of freedom which are useful for various interventions on the tracks; on the other hand, the existence of all or part of these degrees of freedom can be a drawback in particular when the intervention apparatuses 2 are not in operation and when the installation must be moved in its entirety or in groups of elements; also, in addition to the detachable articulated securing means 6, the intervention chassis 4 and the motor modules 5 comprise removable rigid securing means such as keying means (not shown in the drawings), making it possible for example to transport '' a single block, an intervention chassis and two motor modules.
- the chassis 4 or the motor modules 5 can be equipped with a retractable train for driving in transverse movement.
- This transverse drive train is, in the second embodiment, consisting of yokes or blocks 52 arranged under the cross member of the engine module, and equipped with rollers 53, driven by hydraulic cylinders in a movement in the vertical direction; when the installation is at rest or during an intervention on the track, the blocks 52 are in the retracted position and the rollers 53 are not in contact with the ground; on the other hand, for a transverse movement, the blocks 52 are lowered by the jacks, until the rollers 53 reach the ground and moreover the rolling members in the longitudinal direction 3 are detached from it (Figure 5); then, either the rollers 53 are driven in rotation by a motor, or the installation can be pushed or pulled laterally in the direction of the track for example as will be seen below.
- the intervention carriages can also have a stepping device allowing their auto ⁇ transfer from the platform to the track and vice versa.
- This device comprises, in the embodiment of FIGS. 3 to 6, elongated boxes 54 extending in housings open to the lower face of the crossmembers of the motor modules 5, these boxes 54 being slidably mounted along the housings of the crossmembers, that is to say transversely to the carriage, and actuable in this direction by jacks (not visible in the drawings), preferably hydraulic, to extend the cross members selectively on either side of the motor module 5.
- the underside of these boxes is open, and two other preferably hydraulic jacks 55 housed between the walls of the boxes have their cylinder mounted pivoting about an axis 56 passing horizontally through the box 54 and carried by these walls; these jacks 55 inside the boxes 54 are pivotally movable between a position of total retraction in which their longitudinal axes are horizontal and aligned and their respective rods are opposite, and a position of total extension in which their longitudinal axes are parallel and vertical and their respective rods extend downward; these two positions are defined by stops for limiting the rotational movement (not shown), cooperating with the cylinders of the jacks 55; the passage from one to the other position is automatic during the extension or retraction of the cylinder rod, thanks to the fact that the location of the axis of rotation 56 of each cylinder is chosen between the location occupied by the center of gravity of the cylinder when the latter is kept horizontal and in the fully retracted position and that occupied by the center of gravity of the same cylinder when the latter is kept horizontal and in the fully extended position
- the free end of the rod of these interior jacks 55 is provided with a clamp 57 intended to grip the rail R when the jack 55 is in the vertical position.
- a brace 58 of bracing connects the two jacks 55 obliquely removably when the latter are in the vertical position.
- the jacks 55 inside the boxes are controlled towards their extended position, and thus tilt about their pivot axis 56 to come to be placed vertically, and the clamps 57 of the jack rods surround the rails R while the spacer 58 bracing being positioned, the rectangle constituted by the two jacks 55 now vertical, the box 54, and the ground between the two rails R, is prevented from deforming in parallelogram; the telescopic control cylinders of the boxes 54 are retracted, but since the boxes are immobilized by the fact that the clamps 57 grip the rails, the carriage rolls laterally towards the track, then always pulled by these jacks, continues its suspended suspension overhang, until, these being fully retracted, the carriage is exactly above the track; then, the vertical cylinders 55 are themselves retracted as well as the transverse rolling members 53, the carriage descends until its longitudinal rolling members 3 reach the rails, and, after detaching the spacer 58, the cylinders vertical 55 are recalled to their horizontal position between the walls of the boxes.
