Definitions

  • the present invention refers to a railway track gauge changing system to metric gauge where the change takes place automatically; it is therefore not necessary to transfer the load from the train with the original railway track gauge to a new train with a new railway track gauge anymore, or to replace the train axles.
  • the object of the invention is to eliminate the currently existing physical barrier in connection with the gauge change to metric gauge.
  • the invention thus pertains to the railway field.
  • a gauge changing installation refers to a place where trains are adapted to a railway track of a different width.
  • a variable gauge bogie system with a changer where the gauge change does not take place actively or automatically on the corresponding bogie is also known.
  • a system using a fixed frame bogie where the gauge change takes places by means of a wheel displacement complemented by means of a fixed changing platform is also known.
  • the system of the invention is devised for satisfactorily solving the abovementioned drawbacks thanks to performing the gauge change automatically.
  • the system is mainly based on a bogie having a special configuration where the classic axle is eliminated and replaced with two half-axles for each wheel.
  • each bogie is formed by two half-bogies, in combination with the respective connection elements corresponding to a central sleeper and two lateral sleepers.
  • the movement allowing the gauge change takes place when the half-bogies displace on the central and lateral sleepers; during such displacement it is necessary to control that the sleepers do not move laterally when the gauge change takes place; in order to do that, control means are installed in the changer unit.
  • the bogie includes a telescopic guiding system for allowing the two wheels to turn at the same speed.
  • the bogie includes a braking system based on four pneumatic actuators connected to the TFA pipe by means of flexible connections; this provides for the possibility of manually actuating the parking brakes of the bogie by means of actuators.
  • the changer itself, it includes a set of bogie-carrying carriages which move inside a ditch by means of a rack system with metallic wheels displaceable on tracks; this is complemented by lateral displacement bedplates designed for carrying out the gauge change in such a way that the movement of the bogie-carrying carriages may be oscillating, carousel-type continuous or by transfer.
  • the bogie-carrying carriages pull the coach in the train movement direction and leave it on the zone where the lateral displacement bedplates are located, where the gauge change takes places, said pulling taking place by means of the central counter-pivot which forms part of the bogie-carrying carriage itself and which is able to move upwards by means of the action of a reversible electric screw.
  • the use of the abovementioned counter-pivot takes place by means of elevating the load supported by the bogie during a short period of time, the height of such elevation being just some centimeters, in such a way that during that period of time the load is released from the half-bogies, this in turn allowing that upon the action of the lateral displacement bedplates on the half-bogies, locks and central and lateral sleepers, where the lateral displacement bedplates are responsible for the displacement of the tracks which move during the gauge change operation, the bogie gauge change takes place simply and with a lower friction.
  • the elevation movement of the counter-pivot pertaining to the bogie-carrying carriages takes places in two phases, one corresponding to the lower position for pulling the coach, and another corresponding to a higher position where the load is elevated some centimeters for a short period of time for performing the gauge change operation.
  • the same gauge change system could be applied in case the coach comprised a rolling system formed by half-bogies of a single axle.
  • the unlocking is pneumatically actuated by means of suitable actuators, which are actuated by means of suitable reversible screws.
  • another novel feature of the bogie consists in that the central and lateral sleepers are interconnected by means of stiffeners for maintaining the relative position between the sleepers during the gauge change operation.
  • stiffeners connecting the central and lateral sleepers can include ducts for the passage of pressurized air from the central sleeper to the lateral sleepers during the unlocking process, thus allowing for a reduction in the unlocking mechanisms of the changer, that is, allowing for the elimination of the actuators of the lateral sleepers, thereby saving costs.
  • the bogie may be provided on a single central sleeper, without lateral sleepers.
  • the displacement of the half-bogies would take place on a single central sleeper with a cylindrical shape, the half-bogies including prismatic pieces housed in respective recesses provided in the half-bogies for supporting the ends of said central sleeper, with a high resistance elastomeric material provided therebetween.
  • the latching locks would enter in the prismatic support pieces for said central sleeper, allowing it to turn slightly.
  • the telescopic guiding system of the half-axles of the bogies may be complemented by means of a cardan transmission system, or else by means of a torque transmitting flexible coupling system.
  • All the movements will be controlled by means of a programmable computer (central PLC), and the system will additionally be controlled by means of artificial vision equipment which will supervise structural defects, temperatures and geometric shapes, thereby allowing the motorization of the bogie formed by two half-bogies, that is, with four half-axles, by means of geared motors for speeds under 90 km/h, thereby allowing for a high traction capability.
  • central PLC central computer
  • each bogie includes two half-bogies (1) having guides for the bolts used for the locking systems (4), the half-bogies (1) also having recesses or cavities which the lateral sleepers (2) and a central sleeper (3) pass through, and where the locking mechanisms (4) are located.
  • half-bogies (1) include half-axles (5) instead of the conventional axles, there are two grease and suspension boxes on either side of the half-axles (5), as shown in the figures.
  • the electro-mechanic gauge opening and closure mechanism In connection with the electro-mechanic gauge opening and closure mechanism, it includes an opening mechanism (9) for the bogie gauge and a closing mechanism (16) for the bogie gauge which are actuated by means of reversible electric screws (15 and 7), respectively, these mechanisms actuating on the half-bogies (1), on the locking mechanisms (4), lateral sleepers (2) and central sleeper (3), the object of said mechanism being, in case of the sleepers, only to hold them so that they don't slide during the gauge change displacement.
  • the system includes lateral displacement bedplates (14) for displacing the respective tracks (8) on which the bogie moves, as well as for carrying out the bogie gauge opening and closing movement.
  • the system also includes bogie carrying carriages (10) which pull the coach towards the area of action of the lateral displacement bedplates, where the gauge change takes place by means of the displacement of the bogie-carrying carriages (10) along a ditch (13), where the driving force for said displacement is transmitted by a pinion which is independent from the wheels of the bogie-carrying carriage (10), the pinion engaging a rack (11) and being guided through metallic tracks.
  • a counter-pivot (12) provided in the bogie-carrying (10) carriages allows for pulling the bogie, by means of its central sleeper, for elevating the load for carrying out the gauge change.
  • Figure 6 shows the same system applied to half-bogies (1) of a single axle, where the lateral sleepers (2) operate as disclosed above, although in this case the central body where the counter-pivot lies moves together with the lateral sleepers (2), forming a single body.
  • Figures 7 , 8 , 9 and 10 show the same scheme as figures 1 , 2 , 5 and 6 , respectively, with the difference that the former figures include a telescopic guiding system between both wheels for guaranteeing the same rotation speed in both.
  • the electronic installation includes a programmable computer (central PLC) provided in a prefabricated module outside the ditch and adjacent to the hydraulic centrals, for managing the controls, the orders, as well as the changer information, the restrictions imposed on the changer itself and the communication between the components, including also the end limit switches that provide information regarding the relative positions during the maneuvers, as well as analogical displacement transducers, anti-entrance barriers and photoelectric cells which stop all displacements in case of intrusion while operating.
  • central PLC programmable computer
  • the electrical installation also comprises light and sound warning indicators for indicating that displacements are taking place.
  • Figures 11 to 24 show an embodiment improving the embodiment disclosed in figures 1 to 10 , said second embodiment comprising half-bogies (1') having recesses or cavities crossed by the lateral sleepers (2') and the central sleeper (3'), where the locking mechanisms (4') are located which use bolts located in guides provided for that purpose in the half-bogies (1').
  • the half-bogies (1') have respective half-axles (5'), besides which the respective independent grease and suspension boxes (6') are provided.
  • the lateral sleepers (2') and the central sleeper (3') are connected by means of prismatic stiffeners (18) allowing for maintaining the same relative position between said sleepers during the gauge change process, where said stiffeners (18) can include ducts for the passage of pressurized air from the central sleeper (3') to the lateral sleepers (2') during the unlocking process, thus reducing the unlocking mechanisms and eliminating the lateral sleeper actuators located in the changer.
  • Figures 13 , 14 and 15 disclose the gauge opening and closing electro-mechanic mechanism, including internal operation means (9') and external operation means (16') which, together with the displacement of the corresponding tracks (8'), allow for the gauge change.
  • Both the tracks (8') and the internal operation means (9') are displaceable together by means of the lateral displacement bedplates (14'), which in turn are actuated by reversible screws (15'), while the external operation means (16') are actuated by means of other reversible electric screws (20).
  • unlocking actuators (19) which, actuated by the reversible screws (7), actuate on the lateral sleepers (2') and on the central sleeper (3'), by means of an eccentric cam or a pneumatic system, depending on the locking system (4') installed.
  • the internal operation means (9') are retractable by means of the corresponding reversible screw for avoiding any interference with the bogie during the maneuver for exiting from the changer.
  • the system includes bogie-carrying carriages (10') which pull the bogie towards the zone of action of the lateral displacement bedplates (14') where the gauge change takes place, in such a way that the displacement of the bogie-carrying carriage (10') along the ditch (13') takes place by means of the traction force created by a pinion that is independent from the wheels of the bogie-carrying carriage (10') itself, by means of a rack system (11') and guided by means of metallic tracks or on a ground made of resistant reinforced pavement, with the help of the counterpivot (12') which allows for elevating the bogie by means of the central sleeper (3') and elevating the load for carrying out the gauge change, where the bogie-carrying carriage (10') is provided with disc brakes.
  • Figure 16 shows the system applied to single axle half-bogies (1'), where the lateral sleepers (2') operate in the same way as before, although in this case the central body where the counterpivot (12') is located forms a single body with the lateral sleepers (2').
  • Figures 17 , 18 , 19 and 20 show the same scheme as figures 11 , 12 , 15 and 16 respectively, with the difference that the first figures include a telescopic guiding system (17') between both wheels for guaranteeing the same rotation speed in both, where said telescopic guiding system (17') can be complemented by cardan joints or by a torque transmitting flexible connection.
  • Figures 21 and 22 show an embodiment where the system does not include lateral sleepers, and where there is a single central sleeper (3') having a cylindrical configuration mounted on a prismatic piece (21) introduced in each half-bogie (1'), said central sleeper (3') being locked to said prismatic piece (21) by means of bolts provided for that purpose, where said prismatic piece (21) is supported on high resistance elastomeric pieces (22).
  • Figures 23 and 24 show the same half-bogies (1') corresponding to figures 21 and 22 , with the difference that figures 23 and 24 include the telescopic guiding system (17') complemented by cardan joints or a torque transmitting flexible connection provided between both wheels for guaranteeing the same rotation speed in the same.
