Definitions

• the invention relates to a method and an apparatus for positioning a train with a locomotive and several train cars, which are coupled with the interposition of spring forces via train and impact devices.
• it relates to the use of freight wagons in rail traffic and the relative arrangement of such wagons with respect to predetermined stops or markings along a platform edge.
• the accuracy of the positioning of the wagons of a train depends on the type of loading and the nature of the load. So it is e.g. for loading wagons with bulk goods, it is sufficient to position the wagon in sight. If, on the other hand, trucks or rolling containers or other vehicles on wheels or chains have to be rolled across the rails of platforms onto the wagons or vice versa, the individual wagons must be positioned with tolerances of less than 10 cm each in certain cases. This positioning is usually brought about by sight and repeated correction by the staff in cooperation with the engine driver.
• freight wagons are positioned by manually shunting the wagons with a locomotive or shunting locomotive with manual operation of the brakes on the train. Bumpers and inhibitors are also used on siding.
• a comparatively simple, essentially mechanical method or such a device for the automated positioning of all the wagons of a train and thus also of the entire train is not yet in use.
• the object of the invention is to provide a method and a device of the type mentioned, with which it is possible to all wagons to position a train with tolerances of approximately less than 10 cm with respect to a predetermined stationary marking, in order to enable the loading and unloading processes of the wagons to be automated, since such automation relies on such accuracy.
• a first end of the train is pre-positioned and a stop device is activated, that the train moves until a cooperation of the stop device with a counterstop by applying a force acting in the longitudinal direction of the train and further elastic under the stress of the spring forces is extended or shortened that a further stop device is activated at a second end of the train and that the force acting in the longitudinal direction is reduced and the train under the influence of the spring forces counter to the direction of the change in length caused until the further activated stop device interacts with another counter stop Maintaining an elastic bias is moved.
• the invention makes use of the elastic extension and shortening of the train, which is possible due to the tension and push devices connected to the train via springs.
• the basic positioning of the train or the wagon chain with equidistant distances is realized due to the defined, ie fixed arrangement of the two anchor devices with great accuracy to less than 1 cm, so that each individual wagon is subsequently positioned with an accuracy of less than 5 cm.
• the accuracy is independent of the thermal expansion of the train.
• the force acting in the longitudinal direction of the train can be a tensile or compressive force that is primarily exerted by the locomotive. However, it can also be applied in whole or in part from a separate mechanical installation, for example via an in Track bed provided electromechanically or hydraulically operated piston / cylinder arrangement.
• the invention also relates to a device for carrying out the method according to the invention. It is characterized in that at least in the area of the two ends of the train there is provided a stop device which, in the event of activation, interacts with a counter stop either fixed or attached to the train. In the case of counter stops attached to the train, the anchor devices are provided in a fixed position. If, however, the anchor devices are attached to the train, the counter-stops are in turn arranged in a fixed position.
• each stop device has an extendable, that is to say activatable, bolt which interacts with the counter stop assigned to it.
• the latter is preferably provided with a damping device which unfolds its damping effect when the bolts of the stop device strike.
• 1 is a side view of a freight train consisting of several wagons
• FIG. 2 shows an enlarged illustration of the free end of the goods wagon on the left according to FIG. 1 to show the positioning device according to the invention with a stationary counterstop;
• Fig. 3 is a view similar to FIG. 2 with counter stop provided on a wagon and
• Fig. 4 shows a train in e.g. the middle of the train additionally provided counter stop.
• Fig. 1 shows a freight train or train 30 with wagons 1 to 6.
• the invention is of course not tied to this number of wagons, as is also indicated figuratively with the middle cut freight wagons.
• the train 30 is positioned according to the invention.
• a locomotive has already been uncoupled and is not shown.
• the two wagons 1 and 6 at the two train ends are each provided at their outer ends with a positioning device, which basically consists of a stop device 10, 10 'and a counter stop 20, 20', cf. Fig. 2.
• the activatable stop device 10 is arranged on the wagon 1 and the movable stop device 10 ', which is designed in the same way but in mirror image, is arranged at the free end of the wagon 6.
• the outer end of the wagon or wagon 1 according to FIG. 2 is provided with a buffer 26, a transport goods container, e.g. a container 27, a drive or bogie 28 and a base 29 shown.
• the positioning process of the train 30 according to the invention takes place with the aid of the relatively simple and robustly constructed stop devices 10, 10 'with their activatable, height-adjustable bolts 11, 11'.
• the positioning process of the train 30 according to the invention is now as follows: First, the train 30 is stopped by the locomotive by the locomotive driver at a fixed mark that is provided at a certain distance from the recess 7. As a result, the stop 10 is positioned in the region of the recess 7.
• the brand is intended for example on the platform or in the track bed.
• the deviation of the train position from the mark can be 1 to 2 m, since the recess 7 has a length of 4 m, for example.
• the recess 7 can be delimited by a frame. It has a length, seen in the longitudinal direction of the train 30, of approximately 4 m, so that the position of the bolt 11 is given within the recess 7 by the rough positioning of the train 30 as described.
• the train 30 After the bolt 11 of the carriage 1 has been lowered, the train 30 travels about 2 to 3 m in the direction of travel x to apply a tensile stress, as a result of which the bolt 11 of the carriage 1 comes into contact with the damper 21 of the counter-stop 20.
• the locomotive then travels a short distance and thereby tensions the springs of the towing hook and eye connections between the n wagons, in the present case wagons 1 to 6, plus the other wagons indicated in the middle of train 30 according to FIG. 1 .
• the train 30, i.e. the carriage chain is thereby pulled apart elastically. With today's standardized train units, the amount of elastic movement of the carriages is approx. 2 to 5 cm per coupling point.
• the stop device 10 'of the carriage 6 that is to say the first carriage with respect to the locomotive (not shown) and its direction of travel, is above the recess 7' provided in the region of its stop unit and in front of the stop 20 '.
• the Bolt 11 'of the stop device 10' of the carriage 6 unlocks or activates and moves vertically downwards into the recess 7 '.
• the locomotive reduces its tractive force, so that the carriage chain contracts.
• the pin 11 'of the carriage 6 engages with the damper 21' of the counter-stop 20 '.
• the train 30 or the wagon chain is slightly pretensioned between the stops 20, 20 ', and the locomotive can, if necessary or indicated, be tensioned by the train 30.
• the pretension of the carriage chain is absorbed by the two stops or stop frames 20, 20 '.
• the distances between the individual carriages 1 to 6 within the carriage association are compensated for by the fundamentally identical spring forces of the coupling parts (towing hooks and eyes), as a result of which the position of each individual carriage with a tolerance of less than 5 cm corresponds to the desired geometric ideal position. This is the prerequisite for the use of automatic loading and unloading devices, especially in the case of combined rail and road traffic, if truck trailers, containers or the like are to be converted from freight wagons to trucks or to tractors and vice versa.
• the stop device 10 'with bolt 11', recess 7 ', counter-stop 20' of the carriage 6, that is to say the first carriage 6 of the train shown, is not shown separately. They are provided as a mirror image of the illustration according to FIG. 2 and correspond in structure and function to the same elements in FIG. 2.
• the towing hooks and eyelets having pulling devices for connecting the carriages 1 to 6 are connected in a conventional manner to the individual carriages 1 to 6 via the springs or spring forces mentioned, so that these springs are not shown separately.
• the train positioning according to the invention described above with reference to the application of a train pretension to the wagon assembly can also be brought about in kinematic reversal by the application of a pressure pretension, which in turn is primarily generated by the locomotive of the train 30. This therefore moves against the direction of travel X shown in FIG. 1, so that, according to FIG. 2, the bolt 11 comes into contact with the further counter-stop 40 and is supported there.
• the applied compressive force leads to an elastic shortening of the train 30.
• the bolt 11 'of the stop device 10' of the carriage is activated so that it moves downward into the recess 7 '. moves and in turn comes into engagement with the damper 21 'of the counter-stop 20'.
• the train is then under pressure between the counter stops 40 and 40 ', and the locomotive can be braced by the train 30 if necessary.
• the positioning device according to the invention is designed such that the reversing of the mechanical principle according to Fig. 2, the stop device 10 "is provided stationary, while the counter stop 20" is arranged on the wagons 1 to 6.
• a pivot lever 11 corresponds to the height-adjustable pin 11, 11 'according to FIG. 2. It can be pivoted via a hydraulic cylinder 35 from a horizontal position into the vertical position shown in FIG. 3, where it can be used with the Counter stops 20 "of the wagons 1 to 6 cooperates.
• the swivel lever 11 " In its horizontal position, not shown, the swivel lever 11 "is arranged in the recess 7 of the track bed, it not being possible for it to interact with the counter-stops 20, 20 ', 20".
• the cylinder arrangement 35 is pivotally mounted to enable the pivoting movement of the pivoting lever 11 ′′ both on the latter and in the region of the recess 7 as shown.
• the same positioning device as in FIG. 3 is shown in FIG. 4. In this case, however, it is provided as an additional positioning device approximately in the middle of the train to be positioned. In addition to the two positioning devices described at the beginning and end of the train, one or more additional positioning devices according to FIG. 4 contribute to an increased precision of the positioning process.
