Abstract

PURPOSE: To close a freight car protected in an airtight state with fire resistance during alarming by a method wherein an end face opening closed in combination with a side door by a fire louver door formed in an airtight manner and fire- resisting manner is formed in a closed structure being fully closed. CONSTITUTION: Fire louver doors 6-8 are completely opened and raised to a position below a ceiling, the door-shaped door frames of fire louver doors 7 and 8 on both sides are oscillated inward and a door is opened to the full opening width of a freight car. When a cargo is loaded on a vehicle, the side door frame is closed and upper and lower parts are constrained by a cylinder having a constraining means. A central door 6 is then placed on the floor 4 of a freight car. Since the doors 7 and 8 are lowered only to double action doors 10, and 11, the doors pass through the doors 10 and 11. When, during alarm, a human being coming out from the freight car, the louver door armor plate 9 is lowered to a lowermost position, and in this case, the double action doors 10 and 11 are covered with the louver door armor plate 9 from the outside. Simultaneously, compressed air is fed to a rubber hollow deformed section 21 and perfect protection is ensured.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to transportation of vehicles such as freight cars and passenger cars, which can be entered in at least one plane from both end faces and through which people can pass. Regarding freight cars.

[Conventional technology]

Such railway wagons are known in their simplest form from motor-tour trains. The vehicle can be entered and exited from both ends by driving onto the transport surface via the inclined plate to a predetermined stopping place, fixing the position there, and cultivating the process of starting and exiting, which can be carried out in the same way from the front and the rear. It will be done. A person can get out of the vehicle and get back into the vehicle, which leaves a certain space on both sides in addition to the vehicle. Such wagons are usually completely open and are therefore no longer sufficient for the high safety requirements that are currently being imposed, for example when transporting through tunnels.

[Problem to be solved by the invention]

The section on which the present invention is based has been developed by improving the freight cars of the first type, making them suitable for use in tunnels from a safety point of view.
That is, in the event of an alarm, the freight cars should be protected airtight and fireproof so that they can be closed.

[Means to solve the problem]

In order to solve this problem, according to the invention, a structure that can be closed on its entire surface has end openings that can be closed in combination with a pass-through door by means of a fireproof armor constructed in an airtight and fireproof manner.

〔Effect of the invention〕

This allows freight cars, passenger cars, and passenger cars to enter and exit the freight car from the front or rear, respectively, and each freight car is closed by lowering the fireproof armor door on the rear end of the loaded truck, allowing people to pass through in case of an emergency. to be able to exit the wagon through the door or re-enter the wagon.
It is possible to do so. In the case of an alarm, fire protection closures necessary for safety reasons are carried out and at the same time the necessary airtightness is guaranteed.

Therefore, in the event of a fire, in a freight car with no people present, a fire-resistant, airtight space is formed from the outside by the fireproof shutters, into which halogen-substituted hydrocarbon can be supplied as a fire extinguishing agent.

[Embodiment]

Each fire-retardant shutter consists of an armor plate consisting of hinge-shaped irregular cross-section lamellas articulated with each other, a strip-shaped intermediate layer made of fire-resistant and insulating material, and a covering laminate that overlaps, and includes guide rails on both sides and the shutter armor plate. In the under-ceiling guide piece that holds the plate, it is held horizontally under the freight car ceiling in the open state,
In the closed state, it is closed airtight by a sealing device. This provides fire protection and closure according to ISO standard T30.

In a preferred arrangement, the intermediate layer and the covering foil are attached to irregular cross-section foils, each covering foil having an inner layer of refractory insulation material, and in the overlapping area of the covering foils, in each case the outer covering foil is attached to this via 4. The mounting sections are each covered by an outer exposed lamina, and the mounting sections for the intermediate layer and the outer lamina are formed in the irregular cross-section lamina as hooks, rivets, etc. The irregular cross-section foil can be a box-shaped profile filled with insulation. This gives the best overall fire resistance.

According to a preferred configuration of the fire protection armor door for a freight car according to the invention, a rubber hollow profile is provided on the fire protection armor door in order to obtain airtightness, and it is possible to press it against the side and ceiling side of the armor plate of the fire protection door by means of compressed air. The armor plate has another hollow rubber profile on its lower side, which in the closed position rests on the floor of the wagon to prevent leakage. With this sealing device, the air pressure of 50 Pascals can be used within 1 hour.
Airtightness that does not release air of 3 or more to the outside is guaranteed.

A particularly high degree of difficulty, which can only be solved at great technical expense, arises from the necessity of providing a pass-through, which, as in the case of alarms, must be constructed in a fire-tight and gas-tight manner. According to a preferred embodiment of the invention, each end opening of the freight car can be closed by at least two fire-resistant armor doors, in particular of different widths, arranged side by side in one plane, and between the two fire-resistant armor doors. is provided with vertical inner guide rails for both door armor plates, which inner guide rails are joined together with an adjacent outer guide rail to form a door frame;
This door frame has a pass-through door in the lower area, and can swing together with these pass-through doors towards the side wall of the freight car to open the full opening width, and is supported so that it can be restrained in the closed state.
In the closed state, the armor plate guided by the door frame is lowered only to the doorways, and in the event of an alarm it is lowered completely around these doorways to the floor of the wagon.

Three fireproof armor doors are provided for each opening in the wagon, and on either side of the wide central fireproof armor door are doors that can be swung toward the side walls of the wagon and are configured as two-way doors. It is good to have a frame for each.

This configuration allows the unhindered passage of the vehicle by opening almost the full width of the opening for loading and unloading the freight car. After loading, the side door frames are swung inward and locked. The three side-by-side armor plates are then lowered, with the central one being lowered to the floor, while the two side armor plates are lowered to the upper part of the swivel door in the door frame. In case of an alarm, the side shutter armor plates are also lowered to the floor and the desired tightness is achieved by supplying compressed air to the rubber hollow profiles.The important advantages of this configuration are: It is possible to use a completely ordinary swing door made of cloth and there is no need to provide special sealing means.In the case of an alarm, it is sufficient to seal the fireproof shutters that completely close the opening, which is relatively simple. .

Rubber plates are provided on the floor side and the ceiling side of each inner guide rail, respectively, and can be pressed airtightly by the restraining means, thereby further improving airtightness. In order to operate the fireproof armor door, an endless chain is provided horizontally on both sides, and the chain wheel is provided on the opening side armor plate turning shaft and the drive shaft farther from the opening, and the drive motor is connected to this drive shaft. has been done.

〔Example〕

Further details, features and advantages of the invention will become apparent from the brief description of the accompanying drawing, which schematically shows a preferred embodiment of a freight car.

In the schematic diagram of FIG. 1, for the sake of simplicity and clarity, only the sides GL and 2 and the ceiling or roof 3 of the railway wagon, which together with the floor 4 form a completely closed structure, are recognized;
The openings 5 in both end faces can each be closed by means of a fireproof armored door with a pass-through door, which is constructed in a gas-tight and fireproof manner, as will be explained later. A freight car bogie is provided under this structure as usual, but its explanation will be omitted.

The end closures of the wagons can be seen from the drawings. For this reason, the opening 5 is
It has three fire-resistant shutters 6.7.8 arranged side by side in one plane, which are constructed to be fire-resistant according to the 150 standard T30. Each fire protection armor 6.7.8 has an armor plate 9 according to figure 5 of the drawings which can be lowered to the floor 4 of the wagon in the fully closed position and which can be lowered to the floor 4 of the wagon in the fully closed position. As can be seen from the under-ceiling guide piece shown, it is provided in a space-saving manner under the ceiling 3 of the freight car in the fully open position. A flexible m 10.11, which is provided as a pass-through door or a normal passage door, is integrated inside the fire-resistant armored doors 7 and 8 on both sides of the wide central fire-protected armored door 6.

The retention of the fire protection shutter 6.7.8 in the end opening 5 takes place by guide rails. On the outside of each of the openings, vertical extension columns 12, 13 are mounted opposite one another, and to these columns via hinges 14 vertical outer guide rails 15. 16 and inner guide rails 17,18 are provided. These guide rails are therefore grouped together in special frames that can be swung like doors, which extend over the entire height of the end opening 5 and include guide pieces for the armor plates of the three fire-protected armor doors. There is.

, in the closed state these frames are restrained at the top and bottom by pressure cylinders with pin-like restraining means. When loading or unloading a vehicle, these frames are automatically opened and closed by a special drive.

Between the outer guide rails 15, 16 and the inner guide rails, that is, in the area of the side fire-protection armor doors 7 and 8, swingable doors 10 and 11 are swingably supported by hinges 19 in the lower area. This oscillating movement is shown by an arc in FIG. 2 of the drawings. The swivel doors 10, 11 are in the exemplary embodiment provided on the inside, so that the armor plate descends on the outside of the swivel doors 10.11 to the floor 4 of the wagon, allowing a fire-protected closure. Of course, a ma with a flexible door on the outside is also possible. Since fire-tight closure is ensured in case of danger only by the three fire-protected shutters 6.7.8, this A-structure is not subject to any special requirements regarding fire protection and air-tightness.

In order to obtain airtightness that prevents more than 30 centigrade of air from being lost from the freight car within one hour at an air pressure of 50 pascals, the guide rail! 5.16.17.18 and horizontal under-ceiling areas have smuggler means supplied with compressed air.

This is shown schematically in FIG. According to this, the outer guide rails 15, 16 consist of a U-shaped profile that opens towards the shutter armor plate, into which a rubber hollow profile 21 is inserted. The rubber hollow profile 21 extends upwards from the floor along one guide rail to the ceiling area and from there horizontally under the ceiling to the ceiling beams 22 which together with the lateral columns 12° 13 form a holding structure. and then running vertically again in the other guide rail to the floor, so that it forms a one-piece inverted U-shape in order to obtain the best possible sealing. All fire-protection shutters are thus sealed by rubber hollow profiles 21 which are pressed against the door surface with special control by means of compressed air, thereby making the connections airtight. For this reason, the armor plate 9 has a tubular pressed profile on the side, and further has a rubber hollow profile 24 extending horizontally on the lower side, so that this rubber hollow profile does not leak to the floor 4 in the closed state. pressed against. The range of the inner guide rails 17°18 and the range of the outer guide rails 15, 16, which in some cases become doorposts, are made airtight by rubber plates (not shown) installed at the top and bottom, and are indirectly sealed by pressure cylinders during restraint. The rubber plate is automatically pressed against the floor or ceiling of the freight car. It should be noted that structurally the inner guide rails 17, 18 are similar to the outer guide rails according to FIG. ! Since it has a sealing means, its illustration and description will be omitted.

FIG. 5 of the drawings schematically shows an armor plate 9 for use in a fire protection armor door 6.7.8. This armor plate is known from German Patent No. 2,901,400 and consists of profiled lamellas 31 which are articulated with one another and have a forged head piece (not shown) on the end face.

On the smooth side of the irregular cross-section lamina 31, a continuous strip-shaped intermediate layer 33 of refractory and heat-insulating material is provided. middle layer 3
3 is covered on the outside with covering foils 34, which overlap in a scale-like manner, and on the back side of the irregular cross-section foil 31, which is also covered on the inside with a layer of fireproof and insulating material, a box-shaped profile 32 is provided. Installed and filled with fireproof insulation material. The lower end of the armor plate is formed by a rubber hollow profile 24.

The armor plates 9 of the three fire-resistant armor doors 6, 7, 8 are:
According to FIG. 3 of the drawings, it can be raised vertically from its closed position and moved horizontally under the roof 3 of the freight car via a turning axis 25. Its drive takes place via horizontal chains 26 on both sides, to which the respective shutter plate 9 is attached by means of retaining pieces not shown in the drawings.

The chain 26 is hooked onto a suitable chain wheel, and the rear shaft 30 additionally has a drive chain wheel, via which the drive chain 28 of the motor-transmission system acts as a drive unit 29. , thereby opening and opening the fire protection shutters.

The freight car as described above has its fire protection armor doors 6.7.8 fully opened, all the armor plates 9 are raised to a position below the ceiling, and the door-like doors of both lateral fire protection doors 7 and 8 are opened. As the frame is swung inward, the full opening width of the freight car is opened.

When the freight car is loaded and before the train departs, the side door frames are closed and the top and bottom are restrained by pressure cylinders with restraint means. The central fireproof armor door 6 is then completely closed, so that its armor plate is exposed above the rail 4 of the freight car. The armor plate of the lateral fire-protection shutter can only be lowered to a height of 2 mm, ie to swivel 810.11, so that passage through this swivel door is guaranteed.

In the case of an alarm, when a person exits the freight car, a device that detects smoke, which is a characteristic indicator of fire, for example, is automatically activated, and the armor plates 9 of the side fire protection armor doors 7 and 8 are lowered to the lowest position. The universal door 10.11 is then covered from the outside with a shutter armor plate. At the same time, the rubber hollow profile 21 is supplied with compressed air, so that perfect protection from both fire and air technology points of view is guaranteed. Of course, the overall control of the device is carried out in a logical sequence not described here; when the device is opened, each side door frame is automatically opened and locked by pressing a button; After restraint, the three side-by-side fire-protection shutters are activated, with the central fire-protection barrier being lowered to the floor as described above.
Both side fire shutters are lowered to the upper edge of the swivel door. In the event of an alarm, the lateral fire protection shutters are lowered to the floor and compressed air is supplied to the rubber hollow profiles for the purpose of sealing. In the reverse order, the action of the compressed air is first removed, thereby releasing the fireproof shutter.

After a delay of a few seconds, the three fire protection shutters are automatically raised to their uppermost end position, then the side door frame is released, and then the side door frame is fully opened by a drive (not shown), and then This makes loading and unloading of vehicles onto freight cars completely possible.
