Definitions

  • the invention relates to a maintenance device according to the preamble of claim 1.
  • the present invention has for its object to provide a maintenance device with which the handling of such a raised rail car can be carried out reliably and easily.
  • the invention proposes to enable the maintenance of a railway wagon raised above the level of the track reliably and safely by not lifting the railway wagon raised solely by its wheels, but rather by means of supports which support the railway wagon on the body and which correspond to it Purpose of use can be designed either as special power car supports or as special intermediate car supports. Furthermore, the invention proposes to enable the maintenance of the wheel sets of a railway carriage raised in this way in that the wheel sets do not have to be moved under the carriage in the longitudinal direction, but can be removed transversely to the track under the carriage by means of a suitably designed wheel set changer. In this way, depending on the length of the train, a considerable travel distance of the wheelset or bogie detached from the wagon can be saved and thus the maintenance time can be reduced.
  • Fig. 1, 1 generally designates a train with two carriages, a non-driven intermediate carriage 2 as well as a powered power car 3 being referred to as carriages in this application.
  • the two carriages are one in height
  • the track 4 is raised, the track 4 itself being a raised track, which is raised in relation to the floor level.
  • the train 1 was then supported with maintenance devices 6, which are only schematically indicated in FIG. 1 and which support the support points on the body of the wagons
  • the wheel set lifting devices 5 together with the previously released wheel sets or bogies can be lowered, as is indicated schematically in FIG. 2, so that the wheel sets or bogies can be checked, serviced and, if necessary, replaced.
  • This drive head support 6a comprises - as can be seen in particular from FIGS. 4 and 5 - two identical sections 7 and 8, each comprising two supports 9, which are designed as telescopes and comprise an upper movable telescopic element 10, of which two supports 9 of a section 7 or 8 each has a locking pin 11 on the upper telescopic element 10, while on the respective other support 9 of the same section 7 or 8 a cross member 12 is arranged horizontally pivotable, which with the locking pin 11 of the opposite section 7 or 8 can be fixed.
  • the supports 9, on the upper telescopic elements 10 of which the cross members 12 are fastened have hydraulic cylinders for telescoping the supports 9.
  • the other two supports 9, the upper telescopic elements of which have the locking pins can be adjusted in height by hand.
  • they have a gas pressure spring, a cable pull with counterweights or a similar device which compensates for at least a large part of the weight of these upper telescopic elements 10.
  • auxiliary bolts 14 are provided, which are also pivotally mounted and can be fastened to the opposite section with corresponding locking pins. These auxiliary bolts 14 serve to temporarily connect the two sections 7 and 8, which have been moved to the driving head 3 on opposite sides of the track 4, so that a firm bond can then be achieved by pivoting the crossbeams 12. Subsequently The auxiliary bolts 14 can be pivoted back into their starting position parallel to the track 4, so that a space is created below the elevated train 1 in the area of the track 4, through which wheelsets can be moved with the help of the mobile wheelset lifting devices.
  • the maintenance devices 6, in particular the power head supports 6a, are used in the following way:
  • the two sections 7 and 8 are initially provisionally positioned on track 4, on the right and left of the support points provided on the driving head 3.
  • the auxiliary bolts 14 of the two sections 7 and 8 are pivoted out and fixed to the opposite section by means of locking pins. This results in a closed square that can be aligned on track 4. Due to the rollers 15 provided below the supports 9, which can advantageously be designed as swivel rollers, the created combination of the two sections 7 and 8 can be moved together, but the drive head support 6a can also be displaced in a parallelogram-like manner by the articulated mounting of the auxiliary bolts 14, so that the supports 9 can be optimally aligned with the support points of the drive head 3a.
  • the cross members 12 are diagonally opposite, horizontally pivoted on two supports 9.
  • the cross members 12 are parallel to Track 4 aligned and provisionally fixed on the other support 9 of the same section with the help of corresponding locking bolts.
  • each crossbeam 12 is located above a locking pin 11 of the opposite section 7 or 8.
  • the cross members 12 are first raised to two different heights in the area of the supports 9 by means of vertically acting hydraulic cylinders. If the crossbeams 12 are then located above the opposite locking pins 11, they are lowered again, overlap or grip the locking pins 11 and are thereby fixed in their 90 ° position.
  • Each traverse 12 is assigned two manually operated screw jacks 16, the screw jacks 16 being actuated by means of ratchets 17.
  • the screw jack 16 can be pivotally mounted on the cross member 12 so that they can assume a horizontal transport position. From this transport position, the spindle lifters 16 are pivoted and fixed in their vertical working position after the alignment of the cross members 12. The crossbeams 12 are then raised with the aid of the two supports 9 or hydraulic cylinders arranged in the supports 9 until they assume their final working position and working height.
  • a final position correction of the drive head support 6a can now be carried out until cadanically mounted support plates 18 are located on the lifters 16 exactly below the support points of the drive head 3.
  • the user can now reach the ratchet 17 via the ascent 19 and actuates it until the support plates 18 of the spindle lifters 16 come into contact with the support points of the drive head 3.
  • a further actuation of the ratchets 17 leads to the entire drive head support 6a being increasingly loaded, so that the supports 9 lower relative to the sprung undercarriage, that is to say the rollers 15, until foot plates 21 arranged below the supports stand up on the hall floor.
  • the weight of the driving head 3 can be introduced into the hall floor via the lifters 16, the traverses 12, the supports 9 and the foot plates 21, so that the wheel set lifting devices 5 can now be lowered and the driving head 3 can only be raised in height via the driving head support 6a is held above the track 4.
  • the hall floor is suitable for absorbing additional forces at almost any point, so that the carriages of the train 1 are supported safely
  • the power head support 6 is made possible.
  • Fig. 3 the middle car 2 is shown on the right, which is supported by a maintenance device 6, which is designed as a middle car body support 6b.
  • a bogie 22 can also be seen in FIG. 3, which is lowered relative to the raised and supported intermediate carriage 2 and can be moved on the track 4.
  • the middle car body support 6b compared to Fig. 3 is shown on an enlarged scale. It comprises a support 9, which has a sprung undercarriage with rollers 15, the rollers 15 advantageously being designed as swivel rollers.
  • the center car body support 6b is supported on the floor of the hall via an invisible footplate from FIG. 6 after the support 9 has been correspondingly deflected relative to its undercarriage.
  • the support 9 is designed as a two-part telescopic element, the upper telescopic element comprising a guide tube 23 which is movable in height relative to the lower tube.
  • the height of the guide tube 23 can be adjusted by hand, a gas pressure spring 24 being indicated within the guide tube 23.
  • the gas pressure spring 24 causes one Weight compensation of the entire upper part of the support 9, that is, the guide tube 23 and a cantilever arm 25 fastened thereon, which carries a screw jack 26, which in turn can be manually operated by means of a ratchet 27 and the height can be adjusted.
  • a deflection roller with a counterweight can be provided in the guide tube 23 or a similar tool to enable weight compensation of this upper part of the support 9 and thus to enable the height of the support 9 to be adjusted by hand.
  • the intermediate car body support 6b Similar to the power head support 6a, the intermediate car body support 6b also has pivotable rises 19 which can be pivoted from a transport position shown on the left in FIG. 6 to a position of use shown on the right and which enable the personnel to climb to the ratchet 27.
  • the design of the cantilever arm 25 allows a particularly wide free space between two opposite middle car body supports 6b, so that wheel sets or bogies can be lowered from the raised car and moved along the track 4.
  • the center car body support 6b comprises a single support 9 and is not provided in conjunction with other sections or supports, but rather as a single support. As a result, four such mobile middle car body supports 6b are required to support a middle car.
  • the workflow for supporting a middle car is similar to that of the power car:
  • the center car body supports are pre-positioned on the right and left at the two ends of the center car in the area of its support points. Then the guide tubes 23 of the supports 9 are extended and fixed by hand, for example by means of plug bolts. The jacks 26 are then precisely aligned so that the support plates 28 located on the jacks 26 are located centrally under the support points of the center car 2.
  • the support plates 28 can be supported in a cadanically adjustable manner by means of a hemispherical receptacle on the lifters 26, so that they always adapt exactly to the support points.
  • the stairs 19 can be folded out into their working position.
  • the lifters Via the ratchets 27, the lifters are extended until the support plates 28 abut the support points of the center car 2 and continue until the support 9 is lowered against the action of the sprung undercarriage and the foot plates rest on the hall floor.
  • the weight of the car body is introduced into the hall floor via the supports 9, so that the support of the car with the help of wheel set lifting devices 5 can be omitted and these can be lowered.
  • a maintenance device 6 which is designed as a wheel set or bogie changer 6c.
  • the wheel set / bogie changer 6c is also designed as a mobile device and for this purpose has a drawbar 29 at each end of a frame 30.
  • the frame 30 is divided into two sections 31 and 32, as is indicated in particular by the broken line in FIG. 8.
  • the frame 30 has two longitudinal beams 33, each interrupted in the middle and designed to be telescopic by hydraulic cylinders, so that overall a different distance between the two drawbars 29 can be set.
  • the wheel set / bogie changer 6c is designed as a towing vehicle. It has electrohydraulic drives, but not travel drives.
  • the changer 6c has a longitudinal undercarriage with castors which can be designed as swivel castors and of which the two swivel castors at the rear can be stuck in a straight line in driving operation.
  • the changer 6c has its own transverse chassis.
  • wheels 34 are provided on rockers 35, the rockers 35 being able to be pivoted about the central axis of the tubular longitudinal members 33.
  • Fig. 7 the driving position of the cross gear is shown in solid lines, the wheels 34 stand on the hall floor.
  • the retracted position of the cross gear is shown in dashed lines.
  • Each section 31 and 32 comprises an outer docking arm 36 with a contour head 37.
  • the contour head 37 has one or more guide rollers which enable it to be rolled along the rail of the track 4.
  • the outer docking arms 36 are moved out in a controlled manner via hand levers and onto the rail adjacent to the changer 6c lowered.
  • the contour heads 37 encompass this rail in a form-fitting manner.
  • the wheels 34 of the transverse chassis are lowered.
  • the docking arms can be retracted, so that the wheel set / bogie changer 6c is thereby pulled onto the stationary rail and is moved from its illustration in dashed lines in FIG. 8 into the position shown in solid lines.
  • the changer 6c is aligned exactly parallel to the track 4.
  • Each wheelset receptacle 38 is fork-shaped and has two tines 39.
  • the parallel, parallel edges of the tines 39 of a wheelset receptacle 38 are chamfered so that they engage the wheels of a wheelset 40 similarly to a brake pad.
  • the cross gear of the section in question is retracted, so that the changer 6c is now supported on the cross gear of the other section and on the docking arms 36.
  • the section to be corrected is now moved in the longitudinal direction of the track 4 by actuating the hydraulic cylinders in the tubular longitudinal beams 33.
  • the free moving section 31 or 32 now moves in the longitudinal direction of the track relative to the track and relative to the other section, which, with its wheels 34 standing on the floor of the hall transversely to the direction of movement of the hydraulic cylinders, provides firm support which enables the movement of the other, freely movable section.
  • the wheelset receptacles 38 can now be fully extended so that both wheels of a wheelset 40 can be gripped by one wheelset receptacle 38. Now all the rollers of the transverse carriages of both sections 31 and 32 are lowered and additional middle docking arms 36 are extended and placed on the rail of the track 4 adjacent to the changer 6c in order to ensure the best possible overall support of the wheel set / bogie changer 6c.
  • the wheel set receptacles 38 are extended relative to the frame 30 by a unit which can be telescoped several times, as can be seen from FIGS. 9 and 10:
  • the wheel set receptacle 38 is U-shaped overall, the two tines 39 being connected to one another on a common base 41.
  • This wheel set receptacle 38 is opposite a carriage 42 horizontally movable, the carriage 42 in turn being horizontally movable relative to a base element 43.
  • the basic element 43 itself can in turn be moved on two rails 44 transversely to the longitudinal beams 33 with the aid of a hydraulic cylinder 45.
  • the docking arms 36 are connected to one another with the telescopic device via hanging hydraulic cylinders 46.
  • these hydraulic cylinders 46 When these hydraulic cylinders 46 are retracted, the wheel set receptacles together with the telescopic device are raised and pivoted about the side member 33 shown on the right in FIGS. 7 to 10.
  • the entire telescopic device together with the rails 44 is articulated to the longitudinal member 33 so that when the hanging hydraulic cylinders 46 are pulled in, the telescopic device together with the wheel set receptacles is pivoted about this longitudinal member 33 until the wheel set receptacles 38 abut the wheel sets 40 or their wheels.
  • a wheel set / bogie changer 6c can either be used to hold only one wheel set 40 or to accommodate a bogie with two axles, the longitudinal adjustability of the changer 6c by the hydraulic cylinders in the longitudinal members 23 making it possible to adapt the wheel set receptacles 38 to different center distances of bogies of different trains .
  • the bogie or the wheelset can be raised with the help of the changer 6c until the wheels of the railroad car are free from the rail.
  • the docking arms 36 and the hanging hydraulic cylinders 26 can be mechanically locked or there can be another mechanical support between the telescopic device (comprising the wheel set receptacles 38 with the tines 39, the base 41, the slide 42 and the base element 43 on the rails 44 ) and the docking arms 36 take place, so that errors or leaks in the hydraulic system are compensated for and the raised position of the telescopic device and the wheel set receptacles 38 is ensured in any case.
  • the wheel set receptacles 38 first move in hydraulically synchronized until they are on the carriage 42. The remaining stroke of the hydraulic device is then carried out until the wheel set or the bogie as a whole is on the wheel set / bogie changer 6c, as is indicated in FIG. 7.
  • the docking arms 36 can be extended again.
  • the wheel set / bogie changer 6c travels on the wheels 34 of its transverse chassis until it is parked approximately in the middle of the travel path.
