Definitions
- the invention relates to a securing system for a railway device, and in particular for a switch. It also relates to a transport vehicle, in particular a wagon, incorporating such a securing device.
- a railroad apparatus transport wagon comprising a railroad apparatus support platform, having a support surface for the railroad apparatus, the support platform being movable between a position horizontal loading position and an inclined transport position.
- the switch is fixed to the support platform by a lashing mechanism consisting of individual flanges, distributed over the entire switch, arranged between the sleepers of the switch and the platform.
- the company MATISA SA has marketed since 2006 at least one turnout securing mechanism, comprising bars fastening, carrying at one end a hook intended to come into position in engagement with a part of the shoe of a rail of the switch.
- Each bar is slidably mounted in a sleeve articulated to the platform so as to pivot around an axis longitudinal which is perpendicular to the bar. The operator can thus maneuver the bar like a lever, holding it by its free end opposite the hook to rotate it until the hook approaches the rail pad, while adjusting the useful length of the bar by sliding it into the sleeve.
- the invention aims to remedy the drawbacks of the state of the art and to propose a securing system for a railroad apparatus which allows simple and secure handling of the railroad apparatus and is simple to motorise.
- the movement of the fixing member is thus broken down into at least two components, namely a horizontal movement of the carriage carrying the fixing member and a vertical downward movement of the guide rail of the carriage, moreover of very low amplitude.
- This breakdown allows a procedure for securing the turnout to the platform controlled in several successive stages, namely initially the positioning of the fixing device which includes, if necessary, a movement of the carriage along the trajectory defined by the slide, then, in a second step, locking by pressing the slide downwards.
- the support platform is preferably horizontal in the loading position. It can however be inclined, this inclination being less than in the transport position.
- the reference plane is related to the support platform and preferably parallel to the support platform. Preferably, the resultant of the forces induced by the locking member on the slideway and the fixing members does not include any component of translation in the reference plane.
- the path of the carriage defined by the slide is preferably a straight path.
- the carriage is moved along the guide rail by a drive mechanism, motorized or not, preferably self-locking.
- the drive mechanism may comprise, for example, a hydraulic or pneumatic piston actuator, or make use of a rotary motor, in particular an electric motor, and a transmission transforming the rotary movement of the motor shaft into a movement of the carriage along the trajectory defined by the slider. It is possible here to envisage any appropriate mode of transmission, for example by pulleys and cable or transmission chain, by pinion and rack. To obtain a self-locking effect of the drive mechanism, it is preferable to choose to interpose between the motor and the carriage an irreversible transmission mechanism, for example an endless screw mechanism.
- a crank connected to the carriage by a preferably irreversible transmission mechanism.
- the carriage drive mechanism includes a drive and/or control member located on one side of the platform. The operator can thus stand outside the platform during the operation of positioning the fastening member.
- the locking mechanism is such that when the platform is in the horizontal loading position and the securing mechanism is in the unlocked state, the slide has at least one degree of translational freedom per relative to the platform in a horizontal longitudinal direction with preferably a deflection of at least 50 cm, and preferably at least one degree of rotational freedom around a vertical axis, preferably with an angular deflection of at least 10 °.
- the orientation of the slide gives great freedom of positioning of the fixing device of the track device with respect to the track device, and therefore allows the securing system to adapt to track devices of various configurations, or whose positioning on the platform is not precise.
- the locking members are driven from the unlocking state to the locking state by a motorized actuator, or a motorized actuator (54) and an energy accumulator, preferably self-locking.
- a motorized actuator or a motorized actuator (54) and an energy accumulator, preferably self-locking.
- an energy accumulator preferably self-locking.
- the fixing member is movable relative to the carriage between at least one retracted position and one fixing position, the fixing member in the retracted position being located, when the support platform is in the loading position, under a fixing plane parallel to the reference plane and located preferably above the guide rail and the carriage, and the fixing member in the fixing position being located, when the support platform is in the loading position, at least partially above the mounting plane.
- the fixing member is moved by a motorized actuator, or a motorized actuator (54) and an energy accumulator, preferably self-locking, between the retracted position and the fixing position.
- the fixing member is rotatable about a pivot axis between the retracted position and the fixing position.
- the fixing member can for example pivot around an axis of rotation fixed relative to the carriage are also possible, for example a deformable parallelogram connection.
- the fixing member preferably comprises at least one hooking zone intended to be hooked to a part of the track apparatus, preferably a rail, although it is also possible to hook a sleeper of the device of way.
- the fixing member comprises two attachment zones, located, when the support platform is in the loading position and the fixing member is in the fixing position, at different heights.
- the support platform is preferably movable between the loading position and an inclined transport position, preferably by rotation about at least one horizontal pivot axis.
- the path of the carriage extends at least in a direction perpendicular to the pivot axis.
- the two slides can be in line with each other on the same transverse beam of the securing mechanism, or parallel to each other but offset, on two transverse beams of the securing mechanism. which are mutually supportive.
- the fixing member and the other fixing member have hooking zones of the railway apparatus which are turned towards each other or turned in the same transverse direction, and are able to each hang on to a runner of a rail of the railroad crossing.
- the latter relates to a vehicle for transporting a railway device, in particular a wagon for transporting a railway device, comprising a securing system as described above , mounted on a transport frame supported by running gear.
- the positioning of the carriage is preferably carried out by motorized means, preferably self-locking.
- motorized means preferably self-locking.
- the carriage After having positioned the carriage and before stressing the guide rail, the carriage is preferably locked in position relative to the guide rail. This blocking is obtained automatically if the mechanism ensuring the displacement of the carriage, motorized or not, is irreversible.
- the fixing member is preferably moved relative to the carriage from a retracted position to a fixing position, before, during or after the positioning of the carriage bearing the fastener.
- a transport wagon 10 being loaded with a track device 12 of large size, and in particular of width greater than the circulation gauge 200 prescribed for rail transport, for example a switch 12 comprising rails 14 and sleepers 16.
- the transport wagon 10 comprises a frame 18 whose width is less than or equal to the width of the circulation gauge 200, defining a longitudinal axis perpendicular to the plane of the picture 1 and supported by two undercarriages 20.
- a tilting platform 22 for loading and supporting the track device 12 is articulated to the chassis 18 by an articulation 24 allowing pivoting around a horizontal axis parallel to the longitudinal axis of the chassis 18.
- the tilting support platform 22 may be in two or more parts.
- the support platform 22 is preferably a mechanically welded structure and has longitudinal members 26 and crosspieces 28. In the loading and unloading position illustrated in the picture 1 , the tilting support platform 22 is horizontal here.
- a reference plane of the platform will thus be defined, parallel to the latter and also horizontal in the loading position.
- One or more hydraulic cylinders 30, or any other type of motorized actuator, make it possible to pivot the tilting support platform 22 between the loading and unloading position and an inclined transport position illustrated on the picture 2 .
- a securing mechanism is provided, illustrated in the figures 3 to 7 .
- This stowage mechanism is composed of fasteners 32.1, 32.2, in this case hooks, mounted on carriages 34.1, 34.2 which are guided by guide rails 36.1, 36.2 which it is possible to position and attach to the support platform 22, parallel to the reference plane.
- Each fixing member 32.1, 32.2 is secured to the associated carriage 34.1, 34.2 by a pivot connection 38.1, 38.2.
- a self-locking actuator 40.1, 40.2 also carried by the carriage 34.1, 34.2, makes it possible to rotate the fixing member 32.1, 32.2 between a retracted position shown on the figures 3 and 4 and a fixing position illustrated on the figures 6 and 7 .
- the term “self-locking actuator” means an actuator which does not require an external energy input to maintain itself in at least certain reference positions, and in particular in the position for fixing the figures 6 and 7 . It may be an actuator capable of remaining in any chosen position within a predetermined positioning range. This can in particular be obtained by providing an actuator comprising an irreversible transmission mechanism, for example a worm gear, between a motor member and the fixing member. It is also possible to envisage a hydraulic cylinder (as illustrated in the figures) associated with a cylinder rod clamping device, as described for example in the document FR 2 021 471 or in the document WO03/046389 .
- Each fixing member 32.1, 32.2 forms a double hook, with two attachment zones 42, 44 (cf. figure 5 ) located, in the fixing position, at different heights above the carriage 34.1, 34.2 associated. This allows the mechanism to be used interchangeably with switches and crossings with concrete sleepers (of low height) and with wooden sleepers (of greater height).
- one of the attachment zones 42, 44 is intended to come into engagement with the shoe of one of the rails 14 of the track device 12, between two sleepers 16 of the track device 12 .
- the fixing members 32.1, 32.2 are oriented transversely on the same side, in this case so that the gripping areas 42, 44 in the inclined position of the picture 2 , are open upwards.
- the carriage 34.1, 34.2 is guided on the associated guide rail 36.1, 36.2 by any appropriate means, which limits the number of degrees of freedom of the carriage relative to the rail to one.
- the carriage 34.1, 34.2 and the slide 36.1, 36.2 have been illustrated schematically in the figures.
- the slide 36.1, 36.2 can be provided with raceways, for example four raceways, on which rollers or balls associated with the carriage roll. It can also be a slide provided with sliding paths for pads formed on the carriage.
- the slide thus defines a linear trajectory, and preferably rectilinear, for the cart. This trajectory is parallel to the reference plane.
- the slide 36.1, 36.2 can be constituted by a solid rail on the periphery of which the rolling or sliding paths are formed, for example a rail of substantially square or rectangular section, the corners of which are machined so as to form four tracks rolling or sliding.
- the carriage may have a general U or O shape so as to surround the rail forming the slide.
- the slide may be constituted by a hollow rail having a groove forming an elongated cavity, in which are formed at least some of the rolling or sliding tracks, and into which at least part of the carriage penetrates.
- a drive mechanism 46.1,46.2 is associated with each carriage 34.1, 34.2 and ensures its movement relative to the associated slide 36.1, 36.2 .
- the drive mechanism 46.1, 46.2 can for example be a mechanism combining an electric motor 48.1, 48.2 and an endless screw 50.1, 50.2, as illustrated in the figures.
- two carriages 34.1, 34.2 each carrying a fixing member 32.1, 32.2 are associated with two slideways 36.1, 36.2 formed in the extension of one another on a common transverse beam 136.
- the transverse beam 136 constituting the two slides 36.1, 36.2 is fixed in a removable and adjustable manner to the support platform 22, by means of a wedging locking device 52.
- This device comprises, at each end of the transverse beam 136, an actuator hydraulic 54 pivotally mounted on a flange 56 secured to the transverse beam 136, and allowing to move a locking member 58 consisting of a beveled wedge, to bring it into engagement with a corresponding inclined wall 60 of a locking cavity 62 formed in a part integral with a spar 26 of the support platform 22.
- the inclined wall 60 has, in the longitudinal direction of the platform, a dimension D greater than e the beveled wedge 58, so that there is a certain freedom of positioning of each end of the transverse beam 136 in the longitudinal direction of the platform with a clearance of up to 50 cm (25 cm on either side of 'a middle position), which makes it possible to translate the transverse beam, or to rotate it around a vertical axis, by an amplitude angle of up to 10° (+/-5° on either side of the median transverse position illustrated in the figures).
- Longitudinal actuators 64 are provided between support platform 22 and cross beam 136 to effect desired adjustments.
- the stowage mechanism consisting of the slides 36.1, 36.2, the carriages 34.1, 34.2 carrying the fixing members 32.1, 32.2, the locking members 58, the associated cavities 62, and the various actuators 40.1, 40.2, 46.1, 46.2, 54 exists in several copies, in this case at least two, distributed over the length of the support platform 22.
- the docking of the switch 12 to the platform 22 is carried out according to a sequencing illustrated on the figure 3 , 6 and 7 .
- the track device 12 has been placed on the support platform 22, the sleepers 16 of the track device 12 resting on the longitudinal members 26 of the support platform 22, if necessary with the interposition of pads.
- Switch 112 has been positioned so that transverse beam 136 is between two crosspieces 16.
- Fasteners 32.1, 32.2 are retracted to avoid any interference with switch 12 during handling.
- An operator then controls the electric motors 48.1, 48.2 and the actuators 40.1, 40.2 to adjust the positioning of the carriages 34.1, 34.2 and deploy the fasteners 32.1, 32.2, so as to bring the latter into engagement with the rail pads 14 of switch 12.
- the locking members 58 are not in contact with the inclined walls 60, so that the positioning of the transverse beam 136 can also be adjusted using the actuators 64 depending on the positioning of the switch 22.
- the securing mechanism is in the transitional position illustrated on the figure 6 .
- the locking of the transverse beam 136 is carried out after a suitable positioning has been found and after the carriages 34.1, 34.2 have been positioned and the fixing members 32.1, 32.2 brought into engagement with the pads of two rails 14 of the track apparatus.
- the extension of the actuators 54 causes a movement of the beveled wedges 58 moving them away from each other and bringing them into contact with the corresponding inclined walls 60.
- the locking force essentially horizontal generated by the actuators 54 causes at the interface between the wedges 58 and the inclined walls 60 forces having a vertical component downwards, so that the transverse beam 136 is biased downwards.
- the unloading operations take place in the reverse order of the loading operations.
- only one of the two fastening members 32.1, 32.2 associated with the transverse beam 136 can be positioned in engagement with one of the rails 14 of the track switch 12, the other fastening member 32.1, 32.2 remaining in the retracted position.
- two carriages 34.1, 34.2 each carrying a fixing member 32.1, 32.2 are associated with two parallel slideways 36.1, 36.2 formed on two parallel transverse beams 136.1, 136.2 fixed to each other by beams 136.3 so as to constitute a rigid sub-assembly.
- This arrangement allows a greater range of positioning for each carriage 34.1, 34.2 along the path of the associated slide.
- a drive mechanism 46.1, 46.2 is associated with each carriage 34.1, 34.2 and ensures its movement relative to the associated slide 36.1, 36.2 .
- the drive mechanism 46.1, 46.2 can for example be a mechanism combining an electric motor 48.1, 48.2 and an endless screw 50.1, 50.2, as illustrated in the figures.
- two carriages 34.1, 34.2 each carrying a fixing member 32.1, 32.2 are associated with two aligned slides 36.1, 36.2 formed on the same transverse beam 136.
- the slides 36.1, 36.2 have substantially different lengths, the travel of the carriage 34.1 being substantially greater than the travel of the carriage 34.2.
- This arrangement is particularly suitable for switches and crossings 12 whose rail 14 intended to be in engagement with the fixing member 32.2 has a position which varies little, whereas the positioning of the rail 14 intended to be in engagement with the member fixing 32.1 is likely to vary more.
- fasteners 32.1, 32.2 are turned transversely towards each other, that is to say so that the attachment zones 42, 44 face each other. It is understood that when the two fasteners 32.1, 32.2 are engaged, the rail device is laterally locked.
- the same transport wagon can be equipped with securing mechanisms according to one or more of the different embodiments illustrated in the figures, distributed over the length of the platform, in order to adapt locally to the configuration of the track device 12.
- the loading and unloading position of the platform is not necessarily horizontal, but can on the contrary be inclined, naturally less than the transport position.
- the displacement of the fixing member relative to the carriage may not be a pivoting, but a translation or the combination of a translation and a rotation, preferably with a single degree of freedom. It is preferably a plane movement, parallel to a vertical plane. It may be in particular a movement obtained by deformation of an articulated quadrilateral, in particular an articulated parallelogram.
- the fixing member can be adapted to hook not the slider of the rail 14, but the crosspiece 16 of the track device 12. In this case, it is possible in particular to provide for a rotation of the fixing member 32.1, 32.2 around of a transverse horizontal pivot axis.
- Guiding the carriage along the path defined by the slide can be achieved by any appropriate means.
