Description

 The invention relates to railway equipment and can be used to replace bogies in case of changes in gauge, as well as in the repair of wagons.

 When using known devices for moving vehicles from one track to another, there is a need for disengaging the train and various shunting operations, which complicates the replacement of bogies under the wagons. (For example, when working with the device according to A.S. USSR NN 1691189, 1537594, B 61 J 1/10).

 According to the achieved result and the means of achieving it, the closest analogue of the claimed one is a device for replacing vehicle trolleys according to application 95118509/11 (032098) of 10.27.95 (decision to grant a patent for an invention), containing a transborder consisting of two platforms, the upper of which mounted on the bottom with the possibility of lifting to a height exceeding the height of the kingpin, and with the possibility of passage of bogies under the corresponding support beam for the carriage, and on the upper platform there are two sections of the track that are spaced respectively etstvenno step three driveways and transborder movably mounted perpendicularly to access roads.

 The disadvantage of the prototype is the possible misalignment of the pivots of the retractable and installed carts and, as a result, the need to move the installed cart directly under the car manually with visual observation.

 The task arises of accurately installing a new trolley under the car without visual observation.

 The problem is solved due to the fact that in the known device transborder, moving in acceptance perpendicular to access roads and consisting of a platform with two sections of the track, made with the possibility of movement in a vertical plane, two centering trolleys are mounted on each track. Each of the centralizers is a movable, spring-balanced along the path axis and equipped with a gear rack frame with stops, on which a drive shaft with right and left threads with a rotation drive, switched on by a current relay, is installed. Carriages interact with shaft threads with pivotally mounted spring-loaded and equipped with limit switches levers in contact with the axles of the wheels of the carts and stops on the frame, and the gear rack is engaged with the gear of the shaft located across sections of the track and equipped with a brake disk, while the gear wheel is on the second end of the shaft interacts with the gear rack of a centralizer located on a parallel section of the path.

 The alignment of the pivots of the replaceable and installed carts, established with the help of centralizers, significantly saves time and improves working safety conditions when replacing vehicle carts.

 In FIG. 1 is a plan view of a section containing three sections of broken access roads and a transborder located in the gap; in FIG. 2 - fragment transborder with centralizers on two parallel paths; in FIG. 3 is a section AA in FIG. 2; in FIG. 4 - carriage with a lever; in FIG. 5 position of the lever in the diluted position of the carriage.

 On the upper platform of the transborder 1, moving in the pit 2, two sections of track 3 and 4 are stacked, alternating with access roads 5, 6 or 6, 7. To the left of the pit (according to the drawing), removable carts 8 are located on tracks 5 and 7, to the right installed trolleys on the same tracks 9. The pit in the path zone 6 is blocked by supporting beams 10, which are installed in such a way that they are under the car (shown in dashed lines) in the girth of the trolleys. The pit also has rails 11 for moving the transborder.

 Centralizers 12 are mounted inside the rail track of tracks 3 and 4 for each replaceable and installed wheelset 12, each of which is a frame 14 that is movable on bevel wheels 13 and held in the middle position by springs 15 and 16. The drive shaft 18 is mounted on the frame from the drive 17 and stops rotation from the current relay with right 19 and left 20 threads. Also mounted on the frame are rails 21, stops 22 and a gear rack 23. From the rails 21, a carriage 24 is moved along the rails 21 by means of a screw on the drive shaft 18. A lever 26 is mounted on the carriage pivotally on the axis 25 and is provided with a spring stretching 27, to interact with the axis of the trolley 28. Gears 29 and 30 are engaged with the rails 23, mounted on a transverse shaft 31, which is equipped with a brake pulley 32, which receives the moment from the brake 33, mounted on the transborder.

 The device operates as follows.

 The train moves, the car moves from track 6 to a section of track 4 on the transborder and stops above the support beams 10. At the same time, set trolleys 9 are delivered from track 5 to section of track 3 (trolleys 8 are retracted to the left).

 The centralizers 12 are included in the operation. When the shaft 18 is rotated from the drive 17 of the carriage 24, interacting with the right 19 and left 20 threads, they begin to approach along the guides 21. At the same time, the levers 26 move away from the stops 22 and, using springs 27, take a vertical position. With further movement, the carriages located on paths 3 and 4 behave differently.

 Obviously, after stopping the train, the pivots of the wagon trolleys are not directly opposite the pivots of the trolleys installed to replace the old ones.

 Let us first consider centralizers working with wagon trolleys. When the lever 26 (for example, on the left side) abuts against the left axis of the carriage 28, the centralizer’s efforts are clearly not enough to shift the whole structure, and therefore, with the further rotation of the shaft 18, the left spring 15 begins to compress, i.e. the frame 14 together with the shaft 17 begins to shift to the left. The gear rack 23, moving together with the frame, forces the shaft 31 and, therefore, the gear 30 to rotate through the gear 29, due to which the frame of the centralizer located on an adjacent path repeats the movement of the frame in question.

 All this happens until the right centralizer lever rests against the right axis of the trolley, after which a current relay is triggered by an increase in load. The drive 17 is turned off, and the shaft 18 stops rotation. The difference in the operation of centralizers that center individual bogies on an adjacent path is that when the lever 26 is pressed onto the bogie axle, the bogie rolls into the other lever as far as it will go, after which the rotation of the shaft 18 also stops. Since the axles of the centralizers are connected through gear racks 23 and the shaft 31 match, the axles of the pivots of the bogies also coincide.

 After both drives 17 are turned off, brake 33 is applied, the upper platform of the transborder is lowered, but due to the brake, the centralizer frames remain in place, the transborder 1 moves along rails 11 so that the installed trolleys are under the car, the platform rises and the car pivots fall into the holes in the car frame . The centralizers are turned on for the reverse rotation of the shaft 18, the carriages 24 are pulled apart and at the end of their travel, the levers 26 with the stops 22 are deflected so that the axles of the bogies pass over them. The brakes turn off and the frame 14 is in the middle position. The train moves in such a way that the next car is on the transborder, the removed carts from the rail section 4 are rolled out onto the path 7 to the left, the installed carts are rolled up to the right.

 All operations are repeated, but the transborder moves in the opposite direction.
