Description

The invention relates to a track bumper with the features of the preamble of claim 1.

In shunting freight trains are usually compiled so that roll on different, parallel to each other arranged tracks, which are interconnected by switches at both ends, individual freight cars from a so-called Ablaufberg and directed depending on the destination on the various tracks. The rolling motion is often caused by a defined gradient, but can also be generated by an additional drive, such. B. by a Beidrückanlage or a locomotive. On each of the tracks a complete freight train or a group of cars is put together, the foremost of the freight wagons being fixed and the following freight wagons striking the freight wagon standing in front of it and being coupled to it. For this purpose, the individual freight wagons, but especially the first freight wagon, must be reliably braked. For this purpose, especially in the conventional art inhibitors are known.

When braking and fixing arise a number of problems. Thus, the individual freight wagons have a different rolling behavior due to loading and design. The rolling behavior and the braking behavior of the brake shoes are also weather-dependent. The first of the freight wagons must therefore be safely brought to a predetermined location, regardless of its weight and its rolling behavior. For the following cars, it is true that some freight cars hardly roll to the car in front of it and still have to be pushed by a Beidrückeinrichtung or locomotive to be coupled to hit other cars with speed on the car in front of it and tend to push it and thus the Set the wagon group or the whole train in motion.

The first freight car must therefore be very well and very securely fixed so that it will not roll on any further. If he continued to roll, he could collide over the subsequent turnout with an outgoing train. In the conventional art, this is prevented by a large safety distance between the fixing point and the subsequent switch and, if necessary, further safety measures on this section.

Once the freight train is complete, the foremost fixation is removed and the locomotive is coupled to the first freight car. Here, there is the problem that the freight cars must first be pulled away from the foremost fixation or pushed away, so that this fixation device can be removed.

These difficulties in coupling the trains and preventing unintentional release of the foremost fixation as well as their intentional removal during departure lead to the operation of such facilities repeatedly z: u considerable safety problems and even serious accidents. Furthermore, the required large safety distances require a considerable amount of space at shunting yards, which is an economic disadvantage

To overcome these disadvantages, numerous attempts have been made in the past to remedy the situation. That's how it describes US Pat. No. 3,828,688 A. a buffer that can be pivoted downwards, whereby it is possible to mechanically store the kinetic energy of the oncoming freight car in the buffer.

The publication DE 29 32 775 A1 describes a buffer with two split buffer halves, as he already in the DE 884 956 B is described for peak protection in the expiry of a marshalling yard. The two split buffer halves are pivotally hinged to each one arranged outside the tracks abutment and each have a buffer and to a power link between a bearing portion of the abutment and the associated Prellbockhälfte. Gradually, single wagons come to a stop on the folded bumper. After the train is completely assembled, the push triangles are folded down under load, and so fast that the advancing cars do not abut. Due to the considerable forces acting on the buffer, they are designed to be particularly low friction. Another arrangement of this kind is also in the DE 30 38 446 A1 described. However, this removal under load proved to be so difficult and troublesome that this technology was not standard.

The DE 31 29 368 A1 describes a pivotable buffer, in which the folding under load is prevented by the assembled train is first pushed a small distance uphill. This is done by means of a hydraulic motor acting on the buffers. Once the train is pushed far enough, the buffer is retracted quickly and the bumper is pulled away from the clearance of the carriage profile. The disadvantage here is that a considerable power has to be installed for pushing the freight train, as a freight train, which must be pushed against a slope, requires a pushing force of several thousand tons. Because of this effort, this technology has not been successful.

The DE 31 51 795 A1 describes a further pivotable buffer stop, in which no butt triangles are used, but a pivotable telescopic arrangement is used. By a simultaneous pull-pivoting movement of the buffer is pulled away from the car and simultaneously pivoted away from the light profile side and down.

The device is, by design, very elongated, which has the disadvantage that the locomotive can not approach close to the finished train. The train, therefore, if it has set in accordance with the slope after swinging away the bumper in motion, already has speed when he hits the locomotive coupling, which is problematic.

The DE 198 08 555 C1 shows a track bender, which also has no rigid bump triangles, but has two parallel four-bar chains to which the buffers are attached. Via an actuating device, the articulated chain can be moved and thereby the track bumper be folded so that it can be stored between the rails and can be run over.

The object of the invention is therefore to provide a technically simple and at the same time reliable solution which no longer has the described disadvantages.

The invention solves the problem by means of a track bender having the features of claim 1.

In this way, a short construction is achieved, which allows the locomotive to approach close to the finished freight train. The shortening of the distance, which has to be done in a very short time, causes the track bender for a short time has no contact with the freight car and therefore can be swung out of the control clearance of the track.

In addition, characterized in that the hinge device is a three-jointed, wherein the first and the second of the joints are arranged in alignment with the direction of movement of the thrust member, a secure power transmission during the shut-off phase is achieved. During the shut-off phase, the three joints are aligned in a line.

In a further embodiment of the invention it is provided that the movement member and the hinge device form a four-bar link, wherein the fourth joint is arranged vertically below the first joint. Instead of a linear guide results in a circular path for the Pufferendstücke, but this is not a disadvantage in the rapid retraction. The result is a four-bar linkage.

• – das dritte Gelenk eine Verbindung zu einer ziehenden Betätigungseinrichtung aufweist.

In a further embodiment of the invention, it is provided that

• - The third joint has a connection to a pulling actuator.

As a result, can be achieved with little effort, a rapid removal of the buffer from the first car. The train can be either up or down, with no perpendicularity is required.

In a further embodiment of the invention it is provided that the pulling actuator is an actuating cylinder which is arranged below the movable joint. The actuating cylinder can be supported by a spring which is hydraulically tensioned at the beginning of the shut-off phase.

In further embodiments of the invention it is provided that a track bender is provided on both sides of the track. In this case, the two track bumps can be coupled together and operated synchronously.

The invention will be explained in more detail with reference to four sketches. This shows 1 a track bender 100 with a three-link gearbox, 2 a track bender with a four-bar linkage, 3 two coupled track bumpers in the open, and 4 in the closed state.

1 shows the Gleisprellbock invention 100 ; he has two bump triangles 1 on. Between these bump triangles 1 is a toggle mechanism mounted, consisting of a crank member 2 , a coupling member 3 and a push member 4 in a guided tour 5 , Such a leadership 5 can be performed around, with other forms are possible. With this push element designed as a bolt 4 is the buffer plate 6 of the track bumper 100 connected. The bolt can be equipped with appropriate damping and suspension.

The crank link 2 is by means of the third joint 7.3 with the push triangle 1 connected.

During the assembly of the car, the joints become 7.1 . 7.2 . 7.3 as in 1 aligned, wherein thrust member 4 , Coupling link 3 and crank link 2 aligned with each other, whereby the safe power transmission is ensured The forces are on the pivoting device 8th on the foundation of the track bumper 100 transfer.

Once the freight train is assembled, the locomotive drives as close as possible to the track bumper 100 approach. Then at high speed by means of the actuating cylinder 9 the crank link 2 and the coupling member 3 pulled down and thus the push member 4 pulled out of the area where the car can press. As soon as there is no contact with the freight wagons, the entire track berth becomes 100 panned to the side and the rolling freight train can be coupled to the locomotive.

After the wagon group has driven away, the track bender becomes 100 moved back to its original position.

2 shows a variant in which the guide with a lever element 10 connected is. The buffer plate 6 hereby executes a tangential movement. The remaining functions are analogous to 1 ,

3 shows two coupled track bumps 100 in the open state, where the freight train can roll through and is coupled with the locomotive. Here, the function of the toggle joint is visible, which is here in the retracted position

4 shows the embodiment of 3 immediately after the operation of the actuating cylinder 8th before the track bumpers 100 be swung to the side.
