Definitions

  • the invention relates to a device for actuating the closure cover of the filler opening of a tank wagon according to the preamble of claim 1.
  • a tank car which is provided on the upper side with at least one dome, near which the cover is pivotably attached by means of a hinge located near the edge of the opening.
  • the axis of this hinge runs essentially parallel to the direction of travel of the tank car.
  • the cover is held in its closed position by a closing element which is pivotably mounted next to the dome.
  • the axis around which the closing element can be pivoted also runs in the direction of travel. It is located below the lid level.
  • a spring element is assigned to the cover of the known tank wagon, which acts on this cover in the opening direction.
  • the lid of this well-known tank wagon is provided with a handle that enables the lid to be operated manually.
  • the invention has for its object to develop a device for automatically opening the cover of tank cars, so that no operator handling the cover during the opening process is required. Furthermore, the aim is also to automatically close the closure lid in order to at least reduce the workload.
  • the relative movement between the respective curve part and the tank car necessary for actuating the closing arm and for pivoting the cover in its open position can be brought about in a simple manner in that the tank car moves at a slow speed relative to the stationary curve parts along the track carrying it or another guide. or transport track, e.g. a road that is moved.
  • transport track e.g. a road that is moved.
  • the axis of the hinge about which the cover can be pivoted, exactly parallel to the direction of travel.
  • slight deviations are easily possible.
  • the axis about which the locking arm can be pivoted Normally, ie if both axes are arranged exactly parallel to the direction of travel, the axis of the cover and the axis of the closing element will be offset by 180 ° in the circumferential direction of the dome.
  • the cover is advantageously provided on its periphery with a substantially radial projection which projects beyond the edge of the dome and on which the spring element which acts on the cover in the opening direction and is arranged outside the dome engages.
  • the projection and cooperating spring element are expediently offset by a small angle in the circumferential direction with respect to the locking arm.
  • the locking arm which is pivotably mounted in a substantially radial plane with respect to the dome, is advantageously provided with a projection projecting in the direction of the cover, which overlaps the cover in the closed position in order to clamp the latter in its closed position and, for example, to press it against a seal attached to the dome.
  • the locking arm can be provided with an extension above the projection that overlaps the lid, which will normally extend approximately radially to the dome, on which the first cam part engages, which disengages the locking arm from the lid, thus moving the locking arm outwards.
  • a third curve part can be provided which, in the course of a relative movement between the cover and the curve part, engages under the cover in its open position and swivels it into its closed position or almost into it. That is, at the end of this pivoting movement, the cover is at least immediately above the dome, so that it only needs to be pressed against the dome.
  • the latter can be pushed through a fourth curve part, which acts on the top in the course of a relative movement between this and the tank wagon and presses the pivoting of the locking arm into a tight system on the dome, in which at least the top of the lid cooperating with the projection of the locking arm is below the lower limit of the projection is located, the upper limit of its free end inclined from top to bottom runs so that the closing arm is moved under the action of the spring acting on it in the position holding the cover in its closed position.
  • the axles When the axles are mounted essentially parallel to the direction of travel of the tank car, about which cover and locking arm can each be pivoted, the axles will be located outside the vertical plane of symmetry of the tank car parallel to the direction of travel.
  • the pivoting direction of the cover and also the direction of movement of the holding arm depend on the direction of travel or, in the case of a certain direction, on the side of the plane of symmetry on which the axis is located.
  • at least one of the curve parts cooperating with the locking arm and / or the cover is attached in duplicate in such a way that actuation of the locking arm and / or the lid is independent of the position of the hinge and locking element or from the direction of travel of the tank car.
  • the device according to the invention has a number of essential advantages. It is no longer necessary for an operator to climb onto the tank car for the purpose of opening and / or closing the lid. On the other hand, the invention requires no or at least no significant additional effort on the tank car. It is undoubtedly necessary to adapt the lid and the mechanism securing it in its closed position to the automatic actuation. The measures required for this, however, require such little effort that the overall economic advantage clearly outweighs them. No further measures or devices are required on the tank car itself in order to cause the automatic opening and / or closing. In the case of stationary attachment, the curve parts can be designed as simple components that do not require any maintenance.
  • the curve parts also allow, with a corresponding design, to take into account certain deviations which arise in relation to the height of the cover above the street level or track level.
  • the loading condition _ there may still be residues of the previous load in the tank wagon that compress the suspension _ and other influences, the height of the cover of each wagon, e.g. of a train, may vary.
  • the invention readily gives the possibility of compensating for tolerances up to 100 mm. Larger tolerances need not be expected since these are not accepted by the railway companies. Otherwise, the invention reduces the risk of accidents.
  • the embodiment shown in the drawing shows the automatic opening and closing of a closure lid of the filler opening of a tank wagon 12 which can be moved on rails 10 and which is provided on the top side with a dome 14.
  • the latter delimits at its free end a fill opening 18 which can be closed by a cover 16.
  • the cover 16 is pivotally attached to a foot 22 which is arranged next to the dome 14 and is attached to the tank car 12 about an axis 20 which runs parallel to the direction of travel of the tank car 12.
  • a second base 24 is attached to the tank car outside the dome 14 and bears an axis 26 on which a locking arm 28 can be pivoted is appropriate.
  • the axis 26 for the locking arm 28 also runs parallel to the direction of travel of the tank car 12.
  • the plane in which the locking arm 28 can be pivoted runs essentially radially to the dome 14.
  • the locking arm 28 is approximately radial in the direction of the dome 14 projecting projection 30 provided, which is dimensioned and arranged so that its lower limit 32 in the closed position shown in Fig. 3 of the cover 16 the latter at the edge thereof overlaps and thus secures in its closed position, in which the cover 16, possibly with the interposition of sealing elements, not shown in the drawing, bears tightly against the dome 14.
  • the projection 30 is designed such that its boundary surface 34 located there slopes downward in the direction of the free end of the projection 30, that is to say in the direction of the central axis of the dome 14.
  • the locking arm 28 is provided with an essentially vertical extension 36.
  • the locking arm 28 is assigned a spring element 38 which acts on it in the direction of its effective position (FIGS. 3 and 6), in which the projection 30 engages over the edge of the cover 16.
  • the lid 16 is provided at its edge with a projection 40 which, in the closed position of the lid, projects radially outward from the dome 14.
  • a projection 40 which is arranged offset from the locking arm 28 by a relatively small angle in the circumferential direction of the dome 16, engages as a coil spring 42 formed spring element which is attached next to the dome 14 and with its other end on the jacket or the like supports the tank car 12.
  • This helical spring 42 acts on the cover 16 in the opening direction 44.
  • the frame 46 shown in the drawing, bridging the track 10, is assigned to a station located between the levels IV-IV and VV, in which the tank car 12, which can be one of several tank cars of an entire train, is filled. The tank car passes through the area before and after the filling station in the direction of arrow 48.
  • the frame 46 carries some curve parts which serve to bring the lid 16 into the open position before the filling station is reached, so that the tank car fills through the filling opening 18 can be.
  • the curve parts arranged behind the filling station in the direction of arrow 48 serve to bring the cover back into the closed position.
  • the cooperating with the extension 36 of the locking arm 28 cam surface 52 of the first cam part 50 is arranged such that it moves the locking arm 28 around its axis 26 against the force of the spring 28 outwards, that is in the direction of the arrow, in the course of the movement of the tank car 12 54 (FIG. 3) pivots until the projection 30 of the locking arm 28 comes out of engagement with the cover 16.
  • the cover is slightly raised under the action of the spring element 42 assigned to it, which engages on the projection 40 of the cover, that is to say it is pivoted somewhat in the opening direction 44, by such a distance that the second curve part 56 in the course the further movement of the tank car 12 in the direction of arrow 48 engages under the lid.
  • the tank car 12 can now be filled.
  • the tank car 12 comes in the course of its renewed movement in the direction of arrow 28 into the region of a third curve part 58, the curved surface 60 of which initially engages under the cover 16 in its open position and then in the course of the further travel movement due to its course via the vertical Dead center position pivots away, so that the cover 16 then falls back on the dome 14 in the direction of arrow 68.
  • the weight of the lid will normally not be sufficient to bring the latter so far into contact with the seat of the dome 14 that the closing arm 28 springs back into its effective position under the action of the spring element 38, in which the projection 30 the edge of the lid 16 overlaps. Rather, in the normal case, at least in the majority of cases, the lid 16 will sit somewhere on the inclined surface 34 of the projection 30, the locking arm 28 being pivoted somewhat outwards against the force of the spring 38, as mentioned.
  • This intermediate stage of the cover, at which it sits loosely on the dome 14, is shown in Fig. 1 of the drawing between the two levels V-V and VI-VI.
  • the cover 16 of the tank car 12 comes into the area of action of a fourth curve part 64, which is designed as a wheel or roller and acts on the surface of the cover 16, which is pressed downwards into a tight contact with the cover Seat of the dome 14 presses, the closing arm 28 in the course of this last downward movement of the cover 16 into its final closed position is initially pivoted outward against the action of the spring 38 by the cover sliding along the upper boundary surface 34 of the projection 30 and then snaps back its effective position as soon as the upper boundary surface of the cover 16 at the level of the lower boundary 32 of the projection 30 or slightly located below it. In this way, the cover 16 is locked again in its closed position by the closing arm 28.
  • the path by which the locking arm can be pivoted by the spring 38 in the direction of the cover is limited by a stop or the like in such a way that, in its end position, it projects only so far into the range of movement of the cover that the latter in the course of the train its closing movement, the locking arm, apart from the projection 30, can pass unhindered.
  • the curve parts 50, 56 and 58 each arranged twice, so that it is not necessary to bring the tank wagons 12 of a train in a specific arrangement with respect to the position of the axis 20 and the locking arm 28.
  • the train after completion of the filling process against the direction of travel 28 through the area of the frame 46 and the curve parts attached to it to drive it is expedient to arrange the upper region of the frame 46, which carries the curved parts, so that it can be raised and lowered.
  • the two upper beams 66 which run parallel to the track 10 and on which the curve parts are attached via cross members 68, are attached to the vertical supports 72 in a suitable manner such that they can be raised and lowered by means of hydraulic cylinders 70 or otherwise.
