Definitions

• the invention relates to a device with which pre-assembled turnouts or large turnout parts intended for a fixed roadway can be transported to their respective installation location.
• Concrete roadways, bridge structures or comparable other base layers can represent such solid substrates for switches.
• Portal-like cranes are known for transporting preassembled switches or also large switch parts to their respective installation location, which, if the switch is to be connected to an already finished track system, are designed as rail vehicles or, if no finished track system is available, as tracked vehicles. Additional straightening devices are required at the installation location to fine-tune the respective turnout or the respective turnout bulk.
• the transport and alignment of switches and large parts of switches is economically very complex due to the use of such special devices and the relatively low utilization of such devices.
• the invention is characterized in particular by the fact that non-portal-like large devices are required for transporting the preassembled switches or large switch parts. Instead, the points or large parts of the points are transported to their respective installation location by means of one or more transport carriages that can be moved along a track.
• Each transport trolley has a cross member with which it is supported on two tracks of the track.
• the track can be designed as a generally flat truss with longitudinal bars stiffened by cross bars.
• the longitudinal bars can represent the travel rails for the trolley or trolleys. Details for the formation of such a career are shown in the subclaims and in the drawing.
• the trolleys can be supported at three points on the two rails of the track. At least two of these support points are then respectively present on one travel rail and at least one support point on the other travel rail.
• These support points can be formed by roller carriages.
• the multiple rollers present on a running rail preferably have a double-sided wheel flange.
• the roller on the other rail need not have such a double-sided flange; The tracking stability of the trolley is guaranteed by the rollers with a double-sided wheel flange.
• the track can also be formed from possibly already present, fixed rails or from only provisionally installed rails.
• Transport trolleys can then be releasably attached to an auxiliary carrier which can be moved along these rails with corresponding roller carriages. The trolley is then supported only on this auxiliary support on the two tracks of the track; the roller carriages of the transport vehicle hover in the air, as it were.
• the trolley In order to enable the required lateral fine alignment at the installation location of the turnout or the majority of the turnout with a solid surface or a solid carriageway with the help of this transport device, and thus also for the fine alignment on special equipment that would have to be brought in, to be able to do without the trolley can be fastened in the transverse direction, to which or which abutments the switch to be transported can be adjusted and aligned as required transversely to its transport direction by means of tension and / or compression members attached to the abutment.
• the abutments can also be used to hold the switch or the majority of the switch during transport.
• the switch or the main parts of the switch can rest on the carriage or carriages during their transport so that they only rest on the carriage with their rails.
• the sleepers of the pre-assembled turnout or the majority of the turnouts that hang on the rails then hang, as it were, on the trolley (s). It is also possible to attach the switch to the carriage as a whole. Then attach this switch to the trolley without special lifting equipment and again To be able to depend on the transport trolley at the installation location, height-adjustable towbars on the transport trolley make sense.
• the turnouts or the large turnout parts can have support feet on their sleepers with which the sleepers and thus the switch or the major part of the switch can be supported on the solid surface with exact alignment.
• the support feet can be designed in the form of spindle rods passing through the threshold or fastened to the threshold. The switch then stands, so to speak, like a millipede on its support feet. Then the trolley or carriages and the track can be dismantled and removed under the switch without having to move the switch again.
• the transport trolleys can be pulled using conventional traction devices. It is also possible to drive at least one roller of a trolley by motor and thus to move the trolley (s) which are attached to one another by its own motor power.
• height-adjustable support devices are provided. These support devices are preferably provided at the end of the respective cross member. In the drawing, a support device designed in the manner of a screw spindle is shown as an example.

• a transport device 10 (FIG. 1) has a track 12 on which a plurality of transport carriages 14 can be moved longitudinally, one of which is shown in FIG. 2.
• a switch or a large part of a switch can then travel along - in the present example case - a plurality of transport carriages 14 and can thus be transported to the installation location of the relevant switch or the relevant large part of the switch.
• the track 12 has a left and right longitudinal bar 16, 18, the hollow profiles are of a square cross section.
• the cross section of the hollow profiles is 100 by 100 millimeters.
• the wall thickness of each hollow profile is eight millimeters.
• the profile of the cross bars 20 corresponds to that of the longitudinal bars 16, 18.
• the longitudinal bars 16, 18 and the cross bars 20 form an approximately horizontal, flat supporting framework, which is stiffened by diagonal pull cables 22, 24. Such stiffening can be present in end fields or in additional middle fields of the raceway 12.
• the cross bars have a distance 26 of four meters.
• the two longitudinal bars 16, 18, which represent the travel rails for the transport carriage 14, are at a mutual distance 28 of 3.10 meters.
• Each of the transport carriages 14 has a longitudinal beam 30 which is aligned in the longitudinal direction or transport direction 32 and is mounted on the longitudinal bars 16, 18 of the track 12 via double rollers 34, 36 spaced apart in the transport direction 32.
• a cross member 38 is supported with its one end - on the right in FIG. 2 - on the longitudinal member 30.
• the other - in Fig. 2 - left end of the cross member 38 is supported by means of a longitudinal member section 30.2 and a support roller 40 attached to it - in Fig. 2 - left longitudinal bar 16 of the raceway 12.
• this support roller 40 has no double-sided flange.
• the track of the trolley 14 is ensured by the rollers 34, 36.
• a switch or a switch size of which parts a left and right rail 42, 44 is shown or indicated in FIGS. 3 and 4, lies with these rails 42, 44 on the cross members 38 of the several transport carriages coupled to one another in the transport direction 32 14.
• the transport trolleys 14 are coupled by coupling the side members 30 of such transport trolleys 14 together.
• the rails 42, 44 are supported on the cross members 38 of the transport carriages 14 in such a way that the sleepers 46, on which the rails 42, 44 are secured by means of a reinforced elastomer bearing by means of screw fastenings 50 and clamp fastenings 52 are attached, come to lie between the cross beams 38.
• the sleepers 46 are thus transported hanging on the rails 42, 44 by the transport carriage 14.
• Reinforcing bars 45 protrude from the underside of the sleepers 46 in order to ensure stable anchoring of the sleepers 46 in the concrete 47 which is applied between the sleepers 46 and the concrete base 49 after the track section has been installed.
• the switch or the main part of the switch is supported on the concrete base 49 by means of spindle rods 51, 54, which are provided at the respective end of each sleeper 46.
• This support of the sleepers 46 and thus the switch or the major part of the switch takes place at the installation site of these rail parts in the exact longitudinal, transverse and vertical alignment of the rails 42, 44 of these rail parts in question.
• the spindle rods 51, 54 can be extended downwards to different extents and the height of the threshold can thus be positioned exactly above the concrete base 49.
• the rails 42, 44 and thus the piece of track in question are finely aligned with the rails 42, 44 on the transport carriage 14.
• the longitudinal alignment in the transport direction 32 takes place by means of a corresponding fine movement of the transport carriages 14 in this transport direction 32.
• the transverse alignment of the rails 42, 44 takes place by displacing the rails 42, 44 in the transverse direction 58 and thus along the cross beams 38 of the existing transport carriages 14.
• an abutment shoe 60 sits on the cross member 38 next to the left rail 42 at a distance from it.
• This abutment shoe 60 has a U-shaped shape that is open at the bottom, so that it resembles the cross member from above 38 encompasses.
• the cross member 38 has a perforated strip with holes 64 which pass through it at a constant distance (FIGS. 3, 4).
• the shoe 60 is screwed to one of these holes 64.1 (FIG. 2), so that it is immovably fixed to the cross member 38 in the transverse direction 58.
• Cantilever arms 66, 68 project laterally from the shoe 60 and form a screw bearing for one spindle 70 each.
• the free end 72 of the two spindles 70 presses laterally against the foot 74 of the left rail 42.
• a comparable abutment shoe 60.2 is provided on the outside of the other rail 44, so that the two rails 42, 44 are held in the transverse direction 58 between the spindles 70, 70.2 of the two abutment shoes 60, 60.2.
• the abutment shoe 60.2 could also be arranged on the inside of the same rail 42, so that abutments would be present on both sides of a rail. For example, by unscrewing the spindles 70 and screwing in the other spindles 70.2 of the two shoes 60, 60.2, the two rails 42, 44 can be shifted to the right in the transverse direction 58.
• abutment shoes 60.4, 60.6 there are comparable abutment shoes 60.4, 60.6. These have an upwardly projecting cantilever arm 69, in which a spindle 70.4 is likewise rotatably held in a comparable manner. The free end 72.4 of this spindle 70.4 is firmly connected to a U-shaped bearing 80, in which the rail 42 sits with its foot 74. Between the. Rail foot 74 and the U-bearing 80, a lateral gap 82 is present, which is closed by a wedge, not shown in the drawing. This gap 82 takes into account that there are often rails with feet 74 of different sizes on a track section and thus in the area of a switch or a major part of a switch.
• All such rails can then be held with the same U-bearings 80.
• the U-bearing 80 By rotating the spindle 70.4, the U-bearing 80 can be pushed or pulled more to the right or left in the transverse direction 58.
• the two rails 42, 44 can be moved together in the transverse direction 58 by means of an abutment shoe 60.4.
• the second abutment shoe 60.6 shown in FIG. 4 would be unnecessary.
• the respective other abutment shoe 60.6 can be used to limit the maximum displacement in the transverse direction 58; one of the two shoes 60.4, 60.6 then forms an end stop in the transverse direction 58 for the desired displacement path in the transverse direction 58.
• the track 12 sits in the area of its knot formations on base plates (86), which are generally seated on a wooden slat stack 88 of different heights, which in turn is built on the concrete base 49.
• the transport device 10.5 shown in detail in FIG. 5 differs from the transport device 10 described above in that the transport carriages 14 are not supported directly on the track 12, but rather are supported indirectly via an auxiliary carrier 90 on existing track rails 92.
• the auxiliary carrier 90 has a tab 94, 96 on each end. In one tab 94 there are screw holes 98 and in the other tab 96 elongated holes 99. With these screw holes 98 or slots 99, the auxiliary carrier 90 can be screwed onto the cross member 38 of the respective transport carriage 14.
• the elongated holes 99 allow a small tolerance in the transverse direction 58.
• the auxiliary carrier 90 rolls over, on the one hand, flange rings 100 and, on the other hand, a support roller 102, which in turn is fastened at one end and at the other end of the auxiliary carrier 90, on the two track rails 92 present.
• the two track rails of which a track rail 92 is shown in FIG. 5 , are mounted on sleepers 46.5.
• the two track rails 92 already represent the final track section, so that the sleepers 46.5 also form the final bearings for these track rails 92.
• the fastening of the track rails 92 on the sleepers 46.5 therefore corresponds to the fastening of the rails 42, 44 on the sleepers 46 (FIG. 3).
• the track rails 92 or comparable track rails could also be provisionally laid directly on a surface or on another surface only for the purpose of transporting the transport wagons 14.
• the track rails 92 in fact represent the track on which the transport carriages 14 are transported with the rails 42, 44 and their sleepers 46.
• a screw spindle 110 is detachably fastened to both ends of the cross members 38 of the transport carriage 14.
• Each screw spindle 110 has its spindle housing 112 attached to the respective end of the cross member 38 in one of the existing holes 64.
• the hand crank 114 of a respective screw spindle 110 By turning the hand crank 114 of a respective screw spindle 110, the height (double arrow 116) of the spindle housing 112 to which the cross member 38 is attached at the ends can be adjusted along the two feet 118 that reach through the spindle housing 112.
• the transport wagon 14 still rests completely on the track rails 92.
• the transport wagon 14 is supported by its respective cross member 38 via the screw spindles 110 provided at the end, such as for example that Concrete base 49, from.
• the existing 12 between the two spindle feet 118 with its - in relation to FIG. 7 - left longitudinal rod 16 is mounted in height above the concrete base 49 in such a way that by lowering the spindle housing 112, the cross member 38 and thus the rail 42 (44) into the predetermined height-related end position can be brought.
• the support rollers 40 can be supported on the left longitudinal bar 16.
• the track 12 would also have the right longitudinal bar 18 on which the other end of the respective cross bar 38 would be supported with double rollers 36 (FIGS. 2, 3). 7, the lowered position of the sleepers 46 with the respective rail 42 is shown in dash-dot lines.
• the sleepers 46 according to FIG. 7 are only lowered after the auxiliary support 90 has been removed from the respective crossmember 38. As soon as the rail 42 - the same applies to the rail 44 - has been brought into its final position, the crossmember 38 and those on it also become attached screws 110 removed.
