Definitions

  • the present invention relates to a rail chassis group for a rail on a straight rail track and at least one curve and in the transition between the straight rail track and the curve movable crane, especially gantry crane, with at least two, in particular at least four, wheels, the wheels subframe of the rail chassis group wear and the subframe of the rail chassis group wear. Furthermore, the invention also relates to a crane, in particular a gantry crane, with at least one rail chassis group according to the invention.
  • Rail chassis groups for gantry cranes are known in principle.
  • An embodiment of a rail vehicle group is in the EP 1 911 716 B1 described.
  • this document does not deal with the problem of how a rail chassis group for cranes, in particular for gantry cranes, should be configured when the crane has to be driven on the straight and around at least one bend in the rails.
  • the need to guide the rails on which the crane or gantry crane, even around the curve, is nowadays often due to the space available on site, which is an exclusively straight laying the rails on which the crane or gantry crane should drive, no longer allow.
  • the prior art known by public prior art is usually provided to connect two or more wheels, apart from their Laufradrotationsachse rigidly in at least one subframe and the Cornering capability by a corresponding rotation possibility to realize a vertical axis between subframe and superstructure or in the superstructure.
  • the object of the invention is to improve a generic Schienenfahrtechnikssti to the effect that it allows a low-wear as possible driving on the rail on the straight and at least one turn and in the transition between them.
  • a central idea of the invention is therefore to further develop the group of rail vehicles such that at least one of the wheels, preferably each wheel, can be rotated individually about the vertical wheel rotation axis and thus each runner in each point of the curve at straight rail sections and also when cornering the optimal position relative to the rail can take. This is especially true for the transitions between a straight track and a curved rail track ie a curve and vice versa. Due to the optimal position of the wheels on the rails in each section of the rail, ie in the straight line and in the curve, the abrasion and wear on the wheels as well as on the rail is minimized. Another important advantage of the inventive design of the Schienenfahrtechnikssti is that it can be traversed with him comparatively tight curves with comparatively low curve radii.
  • Particularly preferred embodiments of the invention provide for this purpose that at least one of the wheels, preferably each wheel, a separate Subframe is assigned and the subframe is rotatable together with the impeller to the vertical in the operating position impeller axis of rotation.
  • a subframe is generally speaking the support element, in which the impeller is rotatably mounted about its in the operating position horizontally extending impeller rotation axis for rolling along on the rail.
  • the operating position is the position in which the rail chassis group or the crane with its wheels is on the rails and can be driven along the rails.
  • the track group has more than two wheels.
  • the number of wheels per track group is an integral multiple of the number two.
  • a track group with all its wheels runs on exactly one rail.
  • the horizontal impeller rotation axis about which the respective impeller rotates when rolling on the rail in the operating position and in the operating position vertical impeller rotation axis about which the impeller is rotatable for cornering can in principle be arranged so that they are, preferably in a right Angle, cut.
  • Preferred embodiments provide, however, that the wheels for rolling on the rail are each rotatable about a horizontal in the operating position Laufradrotationsachse and, preferably in each case, the impeller rotation axis of the impeller and the impeller rotation axis of the impeller are skewed to each other.
  • the word "windschief" is to be understood in a mathematical sense.
  • the wheels of the track group are the only components of the track group which initiate the load generated by the track group itself and generated by the ballast on the track group in the rails.
  • the invention relates not only to a rail vehicle group per se, but also to a crane, in particular a gantry crane, which is characterized in that it has at least one rail chassis group according to the invention, preferably three or four rail chassis groups according to the invention.
  • gantry cranes is preferably provided that, in order to allow straight travel and cornering on the rails, per vertical support have a rail undercarriage according to the invention.
  • Fig. 1 shows by way of example and schematically a crane 3 in the form of a gantry crane, which can travel on two rails 2 in a straight rail section and also around a curve shown only partially.
  • the crane 3 or gantry crane has at each corner a rail chassis group 1.
  • Each rail chassis group 1 has a plurality of wheels 4, with which they can drive on the rails 2 along the line and around the bend.
  • the wheels 4 of each rail chassis group 1 run on exactly one rail 2.
  • the rail chassis groups 1 can, for example, in each case according to the below-described embodiments of the invention be executed.
  • the Schienenfahrwerks tendency 1 of this embodiment of a crane 3 are seen in pairs and in the longitudinal direction of the rails 2, arranged one behind the other on a head support 20 of the crane 3.
  • the head carrier 20 can also be referred to as a chassis carrier or moving beam and represents the connection between the rolling gear group 1 and the structure of the crane 3 resting thereon.
  • On the head carriers 20 four vertical supports 19 are arranged on the head carriers 20 which carry two main carriers 18.
  • the vertical supports 19 do not necessarily have to be strictly vertical.
  • On the main carrier 18 runs at least one known per se, but not shown trolley, which carries the lifting device. The trolley is movable along the main carrier 18. This is known per se and does not have to be shown separately.
  • Fig. 2 shows in a schematically illustrated vertical section a free on the ground level edge 25 and thus on the ground 24 stationary rail 2. This stands with its rail 23 on the top edge 25.
  • the rail head 21 carries the tread 22 of the rail 2, on which the wheels 4 of Roll down the rolling gear groups 1. Laterally, the rail head 21 is limited by the side surfaces 12.
  • the side surfaces 12 are those surfaces of the rail 2 and the rail head 21, which are arranged outside the running surface 22 of the rail 2 and, based on the operating position, usually vertical or at least approximately vertical. They are usually formed on the rail head 21.
  • the in Fig. 2 schematically illustrated construction is known per se and need not be explained further.
  • Fig. 3 shows schematically and by way of example how, as also known in the prior art, a rail 2 can be installed in the substrate 24 that their tread 22 at least approximately level with the ground level 25th lies.
  • This structure is selected when the rail 2 is not to survive over the ground surface 25. This can be the case, for example, when the rail is installed in the area of a traffic area on which non-rail vehicles such as trucks, cars and the like should drive.
  • the structure of the rail 2 per se is the same as in Fig. 2 ,
  • the essential difference for the following statements between the structure according to Fig. 3 and the structure according to Fig. 2 is that the side surfaces 12 of the rail 2 and the rail head 21 in the according to Fig. 3 built-in ways are no longer completely freely accessible.
  • the side surfaces 12 are according to the rail installation Fig. 3 only within the relatively shallow grooves 26 accessible.
  • Fig. 4 shows the rail chassis group 1 in the region of a curve of the rail 2 in a perspective view.
  • Fig. 5 shows the same situation in plan view.
  • the running wheels 33 resting on the running surface 22 of the rail 2 with their running surfaces 33 are, according to the invention, individually rotatable or pivotable about a respective vertically disposed impeller rotation axis 7 in the shown operating position.
  • Each impeller 4 is assigned a separate subframe 5.
  • Each of these sub-frame 5 is rotatable together with the impeller 4 about the vertically standing in the operating position impeller axis of rotation 7.
  • two of the wheels 4 with their associated subframes 5 are rotatable about a common, vertical in the operating position impeller axis of rotation 7.
  • the Laufradrotationsachsen 8 of the wheels 4 and their respective impeller axes of rotation 7 are skewed. This means that they do not intersect or run parallel to each other.
  • the rotatability of the wheels 4 and subframe 5 in pairs about a common vertically disposed impeller axis of rotation 7 allows the reduction of the number of required hinges 34 to allow the rotatability about the vertical impeller axes of rotation 7. Suitable hinges 34 for this purpose are known per se in the prior art and need not be further explained.
  • the wheels 4 of the respective track group 1 jointly transmit the entire, in the operating position in the vertical direction 9 of the Schienenfahrwerkscade 1 itself outgoing and resting on the Schienenfahrtechniksucc 1 load on the rail 2.
  • the wheels 4 are thus the only components of the rail carriage group 1 intended for the transmission of the ballast 2 to the rail.
  • each rail chassis group 1 has six wheels 4 and correspondingly also six subframes 5, which are each assigned in pairs to a wheel rotational axis 7.
  • the subframe 5 carry the superstructure 6 and also the motors 31, which serve to set the wheels 4 for driving along the rail 2 about their Laufradrotationsachsen 8 in rotation.
  • the superstructure 6 of the Schienenfahrtechniksucc 1 includes, generally speaking, all those components of the rail chassis group 1, which are supported by the subframes 5. These, the superstructure 6 forming components are at least for the most part in the operating position usually above the subframe 5.
  • the superstructure 6 of the Schienenfahrtechniksucc 1 comprises in the embodiments shown a carrier in the form of Balanciers 29, which of four wheels 4 with their four subframes 5 is worn. On the balancer 29, a rocker 28 of the superstructure 6 is supported. This rocker 28 is supported at its other end on two wheels 4 and two subframes 5 from.
  • the horizontal joints 36 serve the most uniform load distribution on the wheels 4 and are known per se.
  • the wheels 4, preferably each impeller 4, at least one rotatable about a vertical in the operating position guide roller rotation axis 16 guide roller 17 for rotating the impeller 4 about the impeller axis 7 by conditioning the guide roller 17 on a side surface 12 of Rail 2 is assigned.
  • the guide rollers 17 are conveniently fastened or mounted with their guide roller rotation axes 16 on the respective subframe 5.
  • the guide roller rotation axes 16, around which the guide rollers 17 rotate when running along the side surface 12 of the rail 2, are aligned vertically, as shown particularly well in the sectional view according to FIG Fig. 6 you can see.
  • Fig. 6 shows a vertical section orthogonal to the longitudinal extent of the rail 2.
  • the cutting plane extends through the guide roller rotation axes 16 of the guide roller 17.
  • the running with its tread 33 on the tread 22 of the rail 2 impeller 4 is in Fig. 6 no longer shown cut, because it is behind the cutting plane.
  • Preferred embodiments, as shown here, provide that each subframe at least two guide rollers 17 are assigned, which are arranged in pairs on opposite sides of the rail head 21. It is particularly preferably provided that at least some subframes 5 four guide rollers 17 are assigned. These may be in pairs on opposite sides of the rail head 21 and in front of and behind the impeller 4 of the subframe 5.
  • An advantage of the first embodiment according to 4 to 6 is that no own drive for rotating or pivoting of the wheels 4 and the subframe 5 is required to the vertically stationary impeller axes of rotation 7, since the optimal orientation of the wheels 4 in the straight ahead and when cornering along the rail 2 by with the side surfaces 12 of the rail head 21 cooperating guide rollers 17 is achieved.
  • this type of rail chassis group 1 according to the invention can only be applied when the rail 2 protrudes so far out of the ground 24 that the side surfaces 12 of the rail head 21 so far beyond the ground level edge 25 that the guide rollers 17 find space accordingly.
  • the rotation of the wheels 4 together with the subframe 5 is realized about the vertically disposed impeller axes of rotation 7 by a guide on the rail 2 and its side surfaces 12.
  • the subframe 5 wheel flange guide wheels 14 which run with their running surfaces 35 on the running surface 22 of the rail 2 and are guided by means of their flanges 15 of the side surfaces 12 of the rail 2.
  • Fig. 9 may be recessed into the ground 24.
  • Fig. 9 shows a vertical section through the rail 2 and a flanged wheel 14 running thereon in the region of the horizontally lying mecanicsradrotationsachse 13.
  • Fig. 9 arranged on both sides of the wheel flange 14 wheel flanges 15, which in cooperation with the side surfaces 12 of the rail 2 cause the guide along the rail 2, so that the in Fig. 9 behind the cutting plane still drawn impeller 4 together with subframe 5 is always brought by turning the vertical impeller axis of rotation 7 in the optimal angular position.
  • a low-wear straight ahead driving and a low-wear cornering on the rail 2 possible.
  • the wheels 4 of the first two embodiments do not carry flanges.
  • Particularly preferred embodiments of these embodiments provide that the flange drive wheel 14 is suspended without load.
  • the superimposed on the Schienenfahrtechnikssti 1 and by the Schienenfahrtechniksucc 1 itself resulting load is transmitted in this embodiment almost exclusively on the wheels 4 on the rails 2.
  • a correspondingly unloaded or load-free suspension of the wheel flange guide wheels 14 can be achieved, for example, in that the guide wheel rotation axes 13 are not supported but only in the vertical direction on the subframe 5 in the horizontal direction.
  • the wheels 4 themselves each have flanges 11. Due to the load transferred from the wheels 4 to the rail 2, however, this is not sufficient for the wheels 4 to be turned following the vertical wheel rotation axes 7 when cornering and during the straight travel or during the transition therebetween by rail 2 alone.
  • a motor Drive 10 is connected, which actively causes a corresponding rotation of the subframe 5 about the impeller axis of rotation 7.
  • at least one of the wheels 4, preferably each impeller 4, a motor drive 10 for rotating the impeller 4 is assigned to the impeller axis of rotation 7.
  • the term of the motor drive 10 is to be understood generally. It may be, for example, by electric motor, hydraulics, pneumatics, etc. motorized drives. Common to all these embodiments that no longer the course of the rail 2 mounted on the subframe 5 guide body for rotation of the wheels 4 and subframe 5 leads to the vertical impeller axes of rotation 7, but these rotations are actively realized by a separate motor drive 10. It can of course be provided that each impeller 4 or each subframe 5 is assigned its own corresponding motor drive 10. It can, as in the embodiment according to the 10 to 12 but also be provided that a motor drive 10 for rotation of two or more subframes 5 is used.
  • Fig. 12 again shows a vertical section through a submerged in the ground 24 rail 2 with it running impeller 4.
  • the impeller 4 preferably all wheels 4, at least one flange 11 for guiding the, preferably respective impeller 4 on at least one side surface 12 of the rail 2 has.
  • the impeller 4 on two flanges 11.
