DETAILED DESCRIPTION OF THE INVENTION

The unit consists of two identical rail freight wagons A, B that are. connected by a short coupler. Each of the freight wagons A, B is. provided with four support columns 6 symmetrically arranged between each other, between the two. 2, which are located in pairs opposite one another at the ends of the wagons or in the area of axle bearings. The upper loading platform 2 is equipped at least at the free ends with the usual short couplings with a lifting device such as a rope, chain or other drive for adjusting the height so that it can be. lower the upper loading platform 2 up to the lower loading platform 3, whereby a change in the height on one side results in the inclination of the upper loading platform according to FIG.

The platforms 2 at the end of the freight wagons with short couplings between the supporting columns can be adjusted, but are only rotatably mounted about the horizontal axis on the supporting columns 1.

At the height-adjustable end of the wagon, the upper loading platform 4 can be locked by means of a locking device on each of the two opposite supporting columns 4. The locking device comprises a first vertically pivotable eye 4 mounted on an upper loading surface 4 which can be pivoted about an axis along the carriage and suspended on a first catch hook 4 mounted on a respective support column 4. A second vertically pivotable arm 4 is suspended with the same deflection axis as the first arm on the loading platform. The second vertically pivotable arm 7 is held in the locking position of the loading platform 2 by a second retaining hook 4 fastened to the support column 6 at a distance from the loading surface. The second vertically pivoting lug 7 ^{and the} second catch hook 6 are arranged below the first vertically pivoting lug 6 and the first catch hook 5.

Vertically, swinging eyes £, 7. they are connected by means of a spring 9 which is arranged between the pivoting eyes 4, 7 in such a way that by the action of the spring 9 the vertically pivoting eyes 4/7. to the support column 1 ......................................... . ..............

Vertically swinging eyes £, 7. are further coupled to an actuating device 10 which allows these lugs 4.7 to be deflected against the action of the spring 9 towards the upper loading platform 4 and counteracts the tension of the spring.

The control device 10 is in the form of a drawbar device, wherein the pivoting lugs 7, 7 are vertically pivotable. they are provided with stops 11 against which the pulling device rests and affects the simultaneous deflection of the two vertically pivoting meshes 7, 7. .

The draw gear is provided below the catch hooks 5, 8. the lower hinge 12 in the form of a triangular plate, which in the first corner 12a is firmly articulated with the car and to the other corners 13a, 14a are articulated to the rods. 13. 14.

The lower hinge 12 is functionally comparable to a two-arm lever, and by providing a hinge in the form of a triangular plate, the articulated rods 13, 14 provide sufficient deflection angle above the rigidly coupled vehicle with the first corner 12a and save hinge mounting space.

The tie rods 13, 14 extend up to the uppermost support hook 17 and are suspended at respective corners 13b or 14b of the upper hinge 15, while its third corner 15a is rigidly articulated with the car.

The first linkage 13 contacts the stops 11 of the vertically pivoting lugs 8, 8 and is intended to control the deflection movement of the vertically pivoting lugs 8, 8. The lower hinge 12 is connected in the third corner 14a to the control lever 18 to control the control device 10.

The control device 10 is further coupled to an optical, preferably a mechanical indicator 19, which clearly and clearly shows the position of the deflection and tilt of the vertically pivoting meshes 7, 7. . The mechanical indicator 19 is provided with an upper hinge 15 as an indicator.

The locking device is provided with a load indicator device 20 with an optical, preferably mechanical, indicator 21 which indicates the lowering of the upper loading platform 5 to at least the first catch hook 5, which is used to lock the horizontal normal, upper loading platform position.

The load indicator device 20 is provided with a cam cam 20 on which it acts, a projection 23 of the first vertically pivotable eye 8 at. its locking and lowering of the first vertically swinging eye 4 of the upper loading platform 4.

In the exemplary embodiment of the load indicator device 20, a guide rod 24 is arranged parallel to the support column 8, which is axially displaceable and spring-loaded from the vehicle by a second spring 25. The guide rod 24 is provided with at least one guide cam 22 associated with the first catch hook. £, cmpoužmvanému-to-a-ge-taci2Ξho¾n¾ΞΓlo-Ž7hé2 íečiΰl ^Ξ ^ l · 7H & yhί- £ j 'ej ¹ £ l horizontal normal position. A further upper, supporting a hook 17 on the support column £ may also assign a timing after the cam 22 on the bar ££, so that each hook support used in L 'to 3 ^e assigned to the adjusting cam 22 of the apparatus for indicating the load on the 20th An indicator 21 is articulated to the upper end of the guide bar 24, which is connected to the support column.

To move the upper loading platform 2 from the locked position, the loading platform 2 is lifted so high that the vertically pivoting lugs 8, 8 can be disengaged from the opening of the hooks 8, 11. The required lift is indicated by the load indicator device 20. The guide rod 24 deflects the indicator 21. In the exemplary embodiment, the indicator 21 is raised by about 90 °.

The vertically pivotable eyelets 8, 8 are deflected by the control device 10 from the support column 4 to the upper loading platform 4. The control device 18 is deflected by the lower hinge 12 - in the example embodiment ^at about 45 - first rod 1-3 is arranged parallel to the support column s-! _ Its position is moved in parallel toward dvnitř £ loading platform. At the same time the height adjustment of the first linkage follows. 13, which is suspended on the upper hinge. 15, whose deflection - in the exemplary embodiment by about 45 ° - is also influenced by the attachment of the indicator in the exemplary embodiment by about 45 °.

Catches 11 of the vertical swiveling eyes £, £ engaging the first rod 13 are reconfigured due to its inward, thereby pulling the first spring 9. deflected vertical swiveling eye £, ... £ · ______________ upper loading platform 3 ^e £ enjoy displaceable by a lifting device into of the desired position, since the pivoting eyes 6, 7 are vertically pivotable. are retracted from the hook 5,8,17 '·

In order to lock the platform, the control lever 18 must be moved back, so that the oscillating eyes 8, 8 are swung back to the starting position by the action of the spring 9. In order to reach a sufficiently clear height in the wagon transition area At the end of the railcar, the upper loading platform 2 can be raised upwards from a horizontal normal position with the possibility of detent on the upper carrying hook 17. When the loading platform 6 is raised, the first vertically pivotable shaft 6 is automatically locked into the upper carrying hook 17. The second vertically pivotable eye 10 remains distant from the loading surface of the respective second catch hook 8 /.

When the loading platform 4 is lifted up and the vertically pivotable eye 6 is located below the upper support hook 17, the vertically pivotable lug 4 first slides on the inner side of the support column 1 and then on the outer profile of the upper support hook 17 by the first spring 9. until the carrier hook 17 engages. Then, the loading platform 4 drops again to such an extent that the vertically pivotable eye 6 assumes the load and the lifting device is unloaded, as indicated by the indicator 21 of the load indicator device 20 as previously described.

In the event that the vertically pivotable eye 6 is pushed to the upper support hook 17 from above, it is necessary to lower the loading platform 2 so that the vertically pivotable eye 6 is properly suspended in the upper support hook 17, indicated by the indicator 21, the cam 22 extends the projection 23 of the vertically pivoting eye 6 while deflecting the indicator 21.

As shown in the exemplary embodiment, with the corresponding selection of the hook spacing, the upper catch hook can be mounted with the first catch hook 5 at a predetermined dimension. and hanging them up. 6. In connection with the desired deflection angle of the upper loading platform 4, the required spacings can not always be realized, so that two load-bearing columns are mounted on the support column.

The control devices 10 for the vertically oscillating pairs of lugs on both sides of the platform 2 are connected to each other by means of a rod transmission (not shown).

When the first vertically pivotable eye 6 or the first catch hook 5 breaks, the platform 2 is supported by the second vertically pivotable eye 7 and the second catch hook 8, the magnitude of the set lowering of the platform 2 corresponding to a preset distance of the second vertically pivotable eye 17 and the support second catch hook 8 ..

Since, according to the safety regulations for lifting platforms, the mechanical locking device must be able to engage in the event of a fall within a maximum of 100 mm, the predetermined distance between the second vertical eye 7 and the contact surface of the second catch hook 8 must be measured accordingly and predetermined up to 100 mm .

In order to ensure a secure grip of the upper vertical swinging eye 4, while the horizontal and vertical tension components are produced when the vertical eye 4 is inclined, the minimum distance between the second vertical swinging eye 7 / the bearing surface of the second catch hook 8 must be preset. Due to the horizontal tensile component, the supporting columns 3 are attracted to the longitudinal supports of the upper loading platform 2, thereby achieving a sufficient calming of the loading platform during ......

driving.

The invention is also applicable to rail freight wagons in which the upper loading platform 2 is mounted rotatably and sliding in the travel direction at the end between two support columns 1. An additional vertical guide of the upper loading platform 2 is then required on the vertical adjustment side.
