Description

Die Erfindung behandelt eine Vorrichtung zum Abnehmen und Wiederansetzen der Puffer an Eisenbahnfahrzeugen bei Instandsetzungen. In der Regel wird der ganze Puffer vom Fahrzeug abgenommen und nach Instandsetzung wieder befestigt. Dieses Abnehmen und Wiederansetzen der Puffer ist eine schwierige, zeitraubende und gefahrvolle Arbeit, besonders bei den gegenwärtig meist benutzten schweren Hülsenpuffern. Mit der Erfindung soll nun die Arbeit des Abnehmens und Wiederansetzens der instand zu setzenden Puffer schnell, bequem und unfallsicher gestaltet werden.The invention relates to an apparatus for removing and reconstituting the buffers on railway vehicles during repairs. As a rule, the entire buffer is taken from the vehicle removed and reattached after repairs. This slimming and reattaching the buffer is difficult, time consuming and dangerous work, especially with the heavier ones currently in use Sleeve buffers. With the invention, the work of losing weight and reattaching should now be done the buffer to be repaired can be designed quickly, conveniently and accident-proof.

Im wesentlichen besteht die Erfindung in einer in der Höhe einstellbaren, zur Aufnahme des Puffers dienenden Tragvorrichtung, die sich im Gegensatze zu der bekannten drehkranartigen, auf den Zughaken des Eisenbahnfahrzeuges aufsetzbaren Vorrichtung auf einen am Gleis befestigten Fuß abstützt. Zweckmäßig wird auch eine seitliche Verstellung und eine drehbare Einrichtung vorgesehen, damit der Puffer vom Fahrzeug abgezogen bzw. in eine Stellung gebracht werden kann, bei der seine Rückseite leicht zugänglich ist.Essentially, the invention consists in a height-adjustable, for recording of the buffer serving support device, which in contrast to the known rotating crane-like, on the tow hook of the railway vehicle attachable device is supported on a foot attached to the track. Appropriate lateral adjustment and rotatable means are also provided so that the Buffer can be withdrawn from the vehicle or brought into a position in which his The back is easily accessible.

Zwecks leichter Handhabung ist die neue Vorrichtung gemäß der Erfindung fahrbar eingerichtet. For the purpose of easy handling, the new device according to the invention is set up to be mobile.

Ein Ausführungsbeispiel ist auf der Zeichnung dargestellt.An exemplary embodiment is shown in the drawing.

Fig. 2 is a plan and

Fig. 3 eine Seitenansicht des Kopfes der Tragvorrichtung mit dem Puffer.Fig. 3 is a side view of the head of the support device with the buffer.

Auf den am Gleis zu befestigenden Fuß A stützt sich die Tragvorrichtung B ab. Er besteht aus den in ihrer Längsrichtung gegeneinander verstellbaren Teilen 1 und 2, an die sich der verbreiterte, als horizontale Führung und Traggestell ausgebildete Teil 3 anschließt. Die Teile 1 und 2 des Fußes werden zweckmäßig als Rohre mit einem mittleren Führungsstück 4 ausgebildet; sie sind durch die leicht zugängliche, mit Rechts- und Linksgewinde versehene Stellschraube 5 verstellbar verbunden. Der Fußteil ι hat einen unteren klauenartigen Vorsprung 6, und an dem gabelartigen, sich verbreiternden Rahmen des Fußteiles 3 sind beiderseitig unten die ebenfalls klauenartigen Vor-Sprünge 7 vorgesehen, die sich gegen die Schienenköpfe des Gleises legen. Der rahmenartige Fußteil 3 ruht mit Walzen auf der Schiene auf. The support device B is supported on the foot A to be attached to the track. It consists of parts 1 and 2 which can be adjusted relative to one another in their longitudinal direction and to which the widened part 3, designed as a horizontal guide and support frame, is connected. The parts 1 and 2 of the foot are expediently designed as tubes with a central guide piece 4; they are adjustably connected by the easily accessible, right-hand and left-hand threaded adjusting screw 5. The foot part ι has a lower claw-like projection 6, and on the fork-like, widening frame of the foot part 3, the claw-like protrusions 7 are provided on both sides below, which lie against the rail heads of the track. The frame-like foot part 3 rests on the rail with rollers.

An der Stelle, wo der Fußteil 2 und der rahmenartige Fußteil 3 zusammenstoßen, ist eine Doppelzapfenverbindung vorgesehen. Der eine Zapfen 8 bildet eine Gelenkstelle, während der zweite Zapfen 9 herausnehmbar ist. Oberhalb dieser Zapfenverbindung ist eine Anschlagfläche 10 vorhanden. Der linksseitige Fußteil ι ist mit einem Handgriff 11 versehen.At the point where the foot part 2 and the frame-like foot part 3 collide a double tenon connection is provided. One pin 8 forms a hinge point while the second pin 9 is removable. Above this tenon connection is a stop surface 10 available. The left foot part ι is provided with a handle 11.

Der Fußteil 3 ist beiderseits mit Laufrollen oder -rädern 12 ausgerüstet, die mittels eines Hebelgestänges in der Höhe verstellbar sind, wie es in Fig. 1 schematisch angedeutet ist. Die Rollen- oder Radachse 13 ist um die Achse 14The foot part 3 is equipped on both sides with rollers or wheels 12, which by means of a Lever linkage are adjustable in height, as is indicated schematically in FIG. 1. the The roller or wheel axle 13 is around the axle 14

Claims

of the lever 15 rotatably arranged. The latter is connected by the toggle rod 16 to the manual lever 18, which can swing around the fixed pin 17 and can be locked in its end positions. The support device B rests on a slide 19 which is horizontally adjustable in the frame-like foot part 3 by means of the spindle 20. This slide carries the hollow guide column 21 rigidly connected to it. In it the spindle 22 can move up and down without being rotated. For vertical adjustment of the screw spindle 22, the nut 24, which is rotatable but not axially displaceable on the hollow guide column 21 by means of a handwheel 23, is used. Instead of the handwheel, a ratchet or ratchet lever can also be used. At the upper end of the spindle 22, a guide piece 25 is axially rotatably mounted in it. On this guide piece rests the horizontally adjustable support piece 26 for the buffer, the setting of which, as can be seen from FIGS. 1 and 3, z. B. can be done by means of a rack and pinion. When the device is out of use, the spindle part 22 of the support device is expediently brought into the lowest position. If the rollers or wheels 12 are brought into the ready-to-drive position, the device can easily be brought to the work site using the handle 11 and the foot parts 1 and 2 serving as a drawbar. In order to give the parts 1, 2 to be used as a drawbar in a convenient position when driving, the bolt 9 is loosened and the parts 1, 2 are moved into the inclined position indicated by dash-dotted lines in FIG. 1. If the device is placed in the right place on the track in front of the vehicle in question (the rollers 27 under the foot part 3 facilitate the longitudinal displacement on the rail), the rollers, if they are in the way, are moved by means of the hand lever 18 and the lever linkage 15, 16 raised. By turning the screw spindle 5, the foot is clamped tightly to the running rails by means of the claw-like projections 6, 7. These are dimensioned in such a way that they can also be used with embedded or sunk tracks. Now the exact setting of the support device takes place in such a way that the upper support slide 26 is as precisely as possible under the center of gravity of the buffer. The lateral distance, perpendicular to the rail, is set by means of the adjusting spindle 20 acting on the carriage 19; the height adjustment takes place by means of the spindle 22 and nut 24 and the adjustment in the longitudinal direction of the buffer axis by means of a rack and pinion. If the buffer weight is intercepted in this way, the screws connecting the buffer to the vehicle can be loosened and the buffer can now be pulled off the vehicle using the upper slide guide. If the buffer is then sufficiently free, it can be turned to the side as desired, which is possible due to the rotatable connection between the screw spindle 22 and the upper part 25, 26. So you can now comfortably repair the safely stored buffer that is ready to work, in particular replace the buffer spring that has become unusable. You can also, if necessary, subsequently lower the buffer released from the vehicle as desired in order, if desired, to bring it to a more comfortable height for the work to be carried out. If the buffer is to be replaced, the device can serve to move away the old buffer and to fetch a replacement buffer. The reattachment of the buffer to the vehicle can also be carried out conveniently after it has been brought to the fastening point with its fastening flange by means of the adjustable support device. As a rule, the horizontal guide provided on the head of the support device is sufficient to pull off the released buffer. If the buffer opposes particularly great resistance to being pulled from the vehicle, a special push-off device of a known type in the form of a clamping spreader, toggle lever spreader, with a screw spindle provided with right and left-hand threads, can be used, one part of the spreader being against the Vehicle front wall and the other part is supported against the edge of the buffer sleeve. The support piece 26 reaching under the buffer can be connected to a swingable retaining bracket, a chain, etc., which surrounds the buffer, in order to reliably prevent the buffer from falling.
