Escape ramp drive

Technical area

The invention relates to an escape ramp drive for a passenger rail vehicle escape ramp.

State of the art

For the evacuation of passengers from rail vehicles, in particular outside of stations or stops the considerable difference in level between the

Passenger room floor and the track bed level too

consider. This level difference can be overcome only by means of a ramp-like construction or a staircase or ladder, otherwise a very large

Risk of injury to the passengers arises. In the

Evacuation of passengers are two ways to differentiate. On the one hand, the passengers on the

Train (track to track) can be evacuated (train to track) or the passengers can be evacuated into another rail vehicle (English, "train to train") Usually ramp-like structures (escape ramps) are used, which is a rest position

Not in use are arranged in recesses of the car body and which are brought in use in a position of use. In this case, operations are to be carried out which require a considerable effort and preferably with a power drive (e.g.

pneumatic drive) are provided. In a

However, evacuation situation may not be due to the presence an energy source (eg the driving voltage) are assumed. Usually provided auxiliary energy storage

(Accumulators, compressed air storage, etc.) can save only a limited amount of energy, so it is too dangerous to operate an emergency facility of these

To make energy sources dependent. Existing solutions therefore use gravity to bring an escape ramp into a position of use. For this purpose, a part of the end wall of a passenger rail vehicle is folded out by means of a swivel joint in the form of a door and the passengers leave the rail vehicle via this door. Another known solution provides an upwardly opening door, which is opened by means of gas pressure accumulator assisted by force and at the same time by means of this power assistance

Escape ramp is brought from a rest position into a position of use. However, these prior art solutions do not allow evacuation of passengers directly into another rail vehicle ("train to train evacuation").

Presentation of the invention

The invention is therefore based on the object, a

Specify escape route drive for a passenger rail vehicle escape ramp, which allows only manual operation and both an evacuation of the passengers to the track bed level and in another

Rail vehicle allows.

The object is achieved by an escape ramp drive for a passenger rail vehicle escape ramp having the features of claim 1. Advantageous embodiments are

Subject of subordinate claims. According to the basic idea of the invention, a drive for an escape ramp for a passenger rail vehicle is set up. This escape ramp is in a rest position below the

Emergency exit of the passenger rail vehicle is arranged and in a position of use, the evacuation of persons from the passenger rail vehicle allows solved, the escape ramp has a frame of at least two sub-frames and these sub-frames are arranged pushed into one another, and a tread is provided, which in

Operating position of the escape ramp forms a walk-in area. In this case, the escape ramp is at rest in a space-saving position below the front end entry of the rail vehicle over which the people are to be evacuated. The escape ramp comprises a frame consisting of at least two (but generally several)

Subframe consists, which are slidably mounted in each other in the manner of the telescope.

In rest position, the escape ramp is located below the emergency exit, typically in the undercarriage chassis.

An inventive escape ramp drive for a

Passenger rail vehicle escape ramp is by

in that the escape ramp is infinitely movable by means of a manually operable drive element between a rest position and at least one use position.

It is provided to use manual operating force to move the escape ramp, since in an evacuation case, the presence of an energy source can not be assumed.

An essential feature of objective invention is that by means of a drive element, this operating force is absorbed and transmitted via power transmission elements to the Components of the escape ramp is transmitted. In this way, the escape ramp can be moved from an operating location.

Another significant advantage of the invention is that an evacuation of the passengers on both the

Track level as well as in another rail vehicle can be done. These two types of evacuation can be realized by the same escape ramp, with only one each different operation is required.

In this case, the escape ramp to a first position of use and a second position of use, wherein in the first position of use the escape ramp extends to the rail level and in the second position of use the escape ramp extends to another rail vehicle.

In one embodiment of the invention, the manual operating force is transmitted by means of cables from the drive element to the components of the escape ramp. That's it

advantageous, a cable drum with a crank drive as

Insert drive element.

In a further embodiment of the invention, the manual operating force is transmitted by means of a fluid in the form of a hydraulic drive from the drive element to the components of the escape ramp. It is advantageous to carry out the manually operable drive element in the form of a hydraulic pump and by means of such pressurized fluid to the operating force on components of the escape ramp

transfer. Instead of a hydraulic drive and the drive can be done by means of a pneumatic drive.

Moving the components of the escape ramp can

advantageously by means of a rod drive in the form a multi-scissors design done. As a result, the advantage can be achieved to be able to realize a high ratio of the applied force in a large extension. This is particularly advantageous because to extend a

Escape ramp no particularly high forces must be overcome, since only the friction of the guides of the individual

Components of the escape ramp must be overcome with each other.

Another, particularly advantageous arrangement for moving the components of the escape ramp provides a cable, which cascading the individual components of the escape ramp

arranged umschlingend and thus allows the extension of the escape ramp by means of traction. This tensile force can be done from any direction, the direction of extension of the escape ramp is irrelevant.

The extension of an escape ramp with a

Escape ramp drive according to the invention can be limited to a certain length (shorter than the maximum extension distance). In this case, a tether is provided, which is attached at one of its ends to the car body of the passenger rail vehicle and which is attached at its other end to a passenger rail vehicle as far as possible remote from the point of the escape ramp and which the maximum

Extend of the escape ramp limited.

In order to realize several different extension distances, it is recommended that the tether with at least two

To equip fastening devices to which it can be connected to the cable attachment point of the car body, so that the maximum extension of the escape ramp is limited to at least two different lengths. In a further development of the invention, it is recommended to use the Ausfahrweitenbegrenzung means of a tether also for automatic lowering of the escape ramp. In this case, the vehicle-mounted fastening device of

To connect tether so with a lowering of the escape ramp that it is triggered upon reaching an extended position of the tether. The lowering device triggered in this way then lowers the horizontally extended escape ramp. In this case, the escape ramp is mounted about a pivot point, which is arranged in the region of the vehicle-side end of the escape ramp and around which the escape ramp is rotatably mounted. The lowering device holds the extended escape ramp in a horizontal position until it is automatically released.

It is beneficial to use the escape ramp with two

To provide use positions. A first use position is used to evacuate people to the level of the rail bed, the frame of the escape ramp is fully extended (to its maximum extension length) and then the side facing away from the rail vehicle is lowered onto the rail bed.

A second position of use serves the evacuation of

Persons into a substantially level-identical further rail vehicle ("train to train" evacuation) .The frame is only extended to the respectively required length which is required to bridge the intermediate space to the further rail vehicle Leave position.

Embodiment of the invention

Fig.l shows an example and schematically a

Passenger rail vehicle with an escape ramp. It is a longitudinal section through a passenger rail vehicle 1 shown in an end-face part, which is equipped with an escape ramp 2. The passenger rail vehicle 1 has an emergency exit door, which is arranged on the front side, for example in the vehicle driver's cab. Below this emergency exit door the escape ramp 2 is arranged. The

Escape ramp 2 comprises a frame 7 of sub-frame 6 (these frames are not shown in Fig.l), which are telescopically slidably disposed and which from the

Retention location (rest position) can be extended. The escape ramp 2 is equipped with a joint arranged on the rail vehicle, which allows both the lowering (angling) of the ramp for the first use position and the maintenance of the substantially horizontal position of the frame in the second position of use.

The accessible area of the escape ramp 2, the tread, is made of flexible material (eg plastic fabric). This tread is in the rest position of the escape ramp 2 in a storage room within the

Passenger rail vehicle 1 rolled or folded

kept. The tread surface is guided on its longitudinal sides on the frame 7 of the escape ramp 2 and attached to these sides sliding on the frame 7. Furthermore, the

Tread on its front side (the extension side edge) with the frame 7 of the escape ramp 2 firmly connected. In such a way, the tread is automatically mitausgefahren in an extension of the frame 7.

Escape ramp drive - cable with linkage. It is one

Top view of an escape ramp 2 shown, the

Tread is not shown. The drive of the

Escape ramp 2 takes place by means of a drive element 3, which is designed in the embodiment shown as a manually operable crank. The rotational movement of this drive element 3 is converted into a linear pulling movement of a rope 4 and passed this pulling movement via the cable 4 to a linkage 5 by Scherengitterart. This

Linkage 5 converts the pulling movement of the rope 4 in a on the last sub-frame 6 of the frame 7 of the escape ramp 2. Solcherart the escape ramp 2 is moved from the rest position into a position of use. At least one point of intersection of the components of the linkage 5 by scissors type are with a sub-frame 6, preferably that of the front side of the

Rail vehicle 1 nearest to connect stationary.

3 shows an example and schematically a

Escape ramp drive - hydraulically with linkage. It is the escape ramp 2 shown in Figure 2, wherein the drive of the linkage 5, a hydraulic drive 8 of two

Hydraulic cylinders is used. The one for the operation of hydraulic drive 8 required fluid pressure is generated by a manually driven pump. This pump can include a power drive, so that in the presence of appropriate energy, the escape ramp can be extended with power assisted.

4 shows an example and schematically a

Escape ramp drive - cable. It is another

Embodiment of an escape ramp drive shown in which a linkage 5 can be omitted. A cable 4 is cascading through the sub-frame 6 of the frame 7 a

Escape ramp 2 out and connected to the last sub-frame 6 at an end attachment 10 fixed to this last sub-frame 6. The sub-frame 6 comprise at the deflection points for the rope each deflections 9. These deflections 9 are possible friction, run, for example in the form of a pulley. The closest to the rail vehicle

Subframe 6 is non-sliding with the rail vehicle

connected. During a pulling movement of the rope 4 in the direction of the arrow, the escape ramp 2 moves out of its rest position.

5 shows an example and schematically an extended escape ramp - horizontal position. An escape ramp 2, comprising three sub-frames 6, is rotatably connected to a passenger rail vehicle 1 by means of a rotary punch 11. The

Escape ramp 2 is extended to the maximum width, which is determined by the length of a tether 13. This

Tether 13 is attached to the, the passenger rail vehicle 1 furthest remote subframe 6 and a

Fastening device 14 is fastened on the rail vehicle side. This fastening device 14 can fix the tether 13 at different lengths to the passenger rail vehicle 1 and thus the extension distance to different lengths limit. The escape ramp 2 is arranged in the example shown in Figure 5 in a horizontal position as it is required for the evacuation of passengers in another rail vehicle. This horizontal position is predetermined by a lowering device 12, which holds the pivotally mounted at the pivot point 11 escape ramp 2 in a horizontal position. By pivoting the lowering device 12, the escape ramp 2 can be angled or lowered. 6 shows by way of example and schematically an extended escape ramp - lowered position. It is that

Passenger rail vehicle 1 of Figure 5 with lowered

Escape ramp 2 shown, the lowering device 12 is swung out. This is the position of the escape ramp 2 required for evacuation of the passengers to the track bed level.

The lowering device 12 may on the one hand be designed as the escape ramp 2 supporting component, on the other hand, the lowering device 12 may be designed in the form of a slotted guide, which is slidably disposed relative to corresponding engaging components of the escape ramp. By shifting the slotted guide such a positive guidance of the curse ramp inclination is given.
