Definitions

  • the proposal is a shop to work at a rail road, such that safety is ensured while the adjacent track remains in operation.
  • This rail maintenance vehicle is mobile, such that during operation it is movable along the track, such that activities that move along the track can be carried out efficiently. Thus it is for sure that no person comes (to close) to the adjacent track to be caught by a train passing by.
  • such vehicle will provide some physical barrier, such as a fence (physical barrier means), such that a person is obstructed somehow to come outside some area and is forced to stay in a safety zone (preferably single level).
  • a fence physical barrier means
  • the shop can have substantially wind and/or water proof roof and/or side walls.
  • the lower side is obviously open, to get unobstructed access to the rails, sleepers, ballast, etc.
  • the inventors have recognised that particularly the flexibility and usability increase, if the shop has one or more of the further specified features or properties.
  • the shop has a carrier frame extending at high level to carry opposing side walls and/or the roof.
  • the carrier frame preferably has a level, such that workers within the shop can stand upright unimpeded. This means actually, that the lower side of the frame is at least 2.5 meter above the rails.
  • the frame is further preferably a space frame to save materials and weight.
  • the shop is preferably width wise adjustable between a slender storage and transport position and a wider operative position, such that workers inside have more movability.
  • This can be obtained to provide that one or both side walls are sideways displaceable.
  • a wall is there fore at a high level pivoting mounted, such that a lower part of the side wall can be sideways displaced.
  • This offers, a.o., structural simplicity and reliable and safe operation. Besides it is easy to offer entrance from aside, e.g. by pivoting the side wall over a large angle.
  • the side walls have a space frame and/or are bulged/buckled in upward direction, a.o. for a low weight and a wide as possible working space.
  • the shop is preferably supported at its ends by an undercarriage and is there between without supports.
  • the carrier frame preferably connects to the undercarriage via an S-shaped frame part.
  • the shop is part of a train with a locomotive at the front and back. Between the locomotives only the shop is preferably present. This offers the possibility to use the undercarriage of the locomotive to carry the shop, such that the shop has no undercarriage of its own. On the other hand the locomotives offer in that case optimum collision protection. Besides, within this train the shop can have undercarriages of its own.
  • the locomotives are preferably of shunting type.
  • they are of diesel or diesel electric type, without pantograph.
  • they have two or three and preferably no more than four wheel shafts, preferably without bogy.
  • the weight is preferably approximately 60 ton and at least 40 and at the most 80 ton.
  • the carrier frame is preferably constructed such that it deforms/buckles upward when a longitudinal compression load is applied. Thus additional safety can be offered to persons within the shop.
  • the carrier frame has for that features, such as a designed weakness.
  • the side walls are suspended from the carrier frame such that the carrier frame relative to the side walls, or vice versa, can make a free displacement of several centimetres, preferably between 2 and 10 cm.
  • the invention is further illustrated by way of a non-limiting embodiment, shown in the drawing.
  • Fig. 1 shows in front view and fig. 2 in side view a rail maintenance vehicle. It has at the ends a dual shaft bogie set below a platform. From the platform a carrier frame as a space frame extends first upward and than horizontally and in cantilever fashion above the track. Between the bogies, downward extending sidewalls are mounted to the carrier frame. The side walls are mounted near the under side of the carrier frame such that they can pivot aside. To the left in fig. 1 an inner storage position and an outer operative position of the side wall are shown. By pivoting the side wall from the storage position beyond the operative position, one can access to the working space by sideways passing below the side wall.
  • the substantially straight side walls are buckled in upward direction such that within the profile of free space the working space can be as wide as possible.
  • the buckle is at a level above the track between about 1.5 and 2.5 meter.
  • a similar effect can be obtained by a bulge as an alternative to the buckle.
  • the roof can not be adjusted width wise.
  • Fig. 2 shows that the lower part of the side walls is closed while the upper part is open.
  • the upper part can also be closed and then preferably light transmissive.
  • the roof can be closed with e.g. locating a cloth over the carrier frame.
  • the shop can only be entered via the front ends.
  • the upward extending part of the carrier frame is provided with a passage opening in the central area. Through said entrance opening a person can walk across the platform above a bogie and into the shop and descend to the ballast bed via a stairs (not shown) at the platform.
  • a person standing at the platform and two persons standing at the ballast bed are illustrated.
  • the lower side of the horizontally extending part of the carrier frame is at a level above the heads of all three persons.
  • the side walls are mounted to the carrier frame such that its centre can deflect about 10 cm upward or downward, without forcing the side walls to follow this deflection. Thus the side walls remain free from deformation during collision.
  • the platforms above the bogies are provided with bumpers and couplings with which during operation a locomotive is directly coupled.
  • the forces acting between the locomotives are transferred via the carrier frame.
  • the carrier frame provides so to speak a spine for the shop.
  • Different embodiments also belong to the invention.
  • the platforms are rigidly coupled with the locomotives, such that the loads from the shop are carried by the wheels of the locomotives.
  • the carrier frame is mounted to the platform such that it is able to pivot around a vertical axis, such that the train can pass a curve without a problem.
  • the bumpers are removed from the locomotives and at that location the platform (also without the bumpers) is screwed to the locomotive.
  • a side wall is preferably near its upper edge at its end pivotably mounted to the from the platform upward extending structure. Between said ends the side wall makes contact with the there above extending carrier frame at spaced locations along its length. Said contact is designed such that the relevant contact point of the side wall can freely move up and down and to the front and back and is only held by the carrier frame in sideways direction to the inside and/or outside.
  • the carrier frame offers the side wall merely support along its length in case of sideways wind loads.
  • the side walls preferably deform outwardly. This is preferably provided by eccentrically loading the side walls during collision or to generate torsion in it.
  • another part of the train/shop applies a load to the side wall, which load is preferably applied after sufficient deformation is obtained in a structural part due to the impact.
  • the side wall preferably has a convenient projection at preferably its inner side, to which the load can be applied. The projection is preferably present substantially at the level of the platform or another level substantially below the level of its pivoting mounting.
  • the carrier frame is bend upward during collision since it has a torsion stiff connection with the structure extending upward from the platform.
  • the collision behaviour can be specified as follows: The collision forces are applied a low level, e.g. at the platform.
  • the carrier frame will first bend upward and then possibly buckle upward.
  • the side walls remain initially undeformed while the carrier frame bends upward.
  • the distance between the platforms decreases.
  • each platform or a component of it applies a load to the projection of the side wall, directed towards the opposite platform.
  • the side wall will thus first bend outward and subsequently possibly buckle outwardly.
  • the projection of the side wall was longitudinally spaced from the relative component/platform, such that unimpeded movement of the side wall was allowed.
  • carrier frame 1 upward extending structure 2; platform 3; side wall 4; projection 5; location of person's head 6; undercarriage 7.
