Definitions

the invention relates to an underfloor lifting system according to the preamble of claim 1.
An underfloor lifting system from the DE 10 2005 022 478 A1 is known.
the lift height to be effected, by which, for example, a bogie or a car body of a rail vehicle can be raised, is predetermined by the central lifting device in this known underfloor lifting system and corresponds to the lifting height of this central lifting device.
the individual support elements extend from the central lifting device to the individual points at which the bogie or the car body is to be supported and raised.
a pit In order to enable a certain lifting height, a pit must be created in the known underfloor lifting system, the depth of which has the degree of the desired lifting height.
a lifting platform is known in which a hydraulic telescopic cylinder is provided as a common drive for two telescopic lifter, and a mobility of an upper compared to a lower telescopic stage of each telescopic lift is effected by a tension element and various pulleys.
a device for changing underfloor components on rail vehicles wherein a central drive is provided for two lifting means of a telescopic lifter. This central drive is not arranged between the two lifting means, but on one side beyond the two lifting means.
the invention has for its object to improve a generic underfloor lifting system to the effect that this with the lowest possible, d. H. flat as possible pit can be realized and is economically feasible.
the invention proposes to design the lifting device with at least two telescopic stages, so that in the collapsed or retracted state, the lifting device requires considerably less height than in the extended state.
the foundation for the underfloor lifting system can therefore be relatively flat and be considerably lower than the extended lifting device.
the construction costs for the underfloor lifting system are advantageously influenced and secondly, a high degree of operational reliability is given, for example, in areas with high groundwater levels, in which by the corresponding flat design of a pit penetration of groundwater can be avoided.
the lifting device has a plurality of telescopic lifters, so that in each case a telescopic lifter is provided below each point which is to be supported and lifted.
a telescopic lifter has at least two telescopic stages, which are height-adjustable by means of so-called lifting means. It is proposed by the proposal that the lifting means of these two height-adjustable telescopic stages are coupled together and that in an economically advantageous embodiment, only a single central drive for this means of a telescopic lifter is provided.
the coupling of the lifting means not only cost saving the purchase of a single drive instead of separate drives for each lift is possible, but it is also a complex synchronization between the individual lifting avoided by automatically actuated by the coupling both lifting means of two telescopic stages simultaneously and moved when the central drive acts on these two coupled lifting means.
the lifting means of the lower of the two movable telescopic stages are arranged substantially below the carrying point at which the load is introduced into the relevant support element. In this way, comparatively small moments, which act on the telescopic column of the telescopic lifter, which also supports its most economical design, since the individual components of the telescopic lifter must accordingly only record the lowest possible loads.
the lifting means designed as spindle drives, each with a spindle and a nut are. This not only represents a cost-effective and reliable design of the lifting means, but also causes a high degree of security, since the spindles are usually self-locking, so in case of failure of the drive the telescopic lifter maintain their respective position even under load and not automatically by the be lowered acting load.
the spindle drives act according to the present proposal as follows: the spindle of the lifting means of the lower movable telescopic stage is rotatably mounted, and on the spindle either up or down running mother is connected to the lower movable telescopic stage, that the lower movable telescopic stage in common is vertically movable with the nut relative to the spindle.
the spindle of the lifting means of the upper movable telescopic stage is rotatably mounted and connected to the upper movable telescopic stage such that this rotatable spindle is vertically movable relative to the mother of the lifting means of the upper movable telescopic stage.
the ratios of the individual lifting means of one and the same telescopic lift can be designed differently, so that the respective higher telescopic stages are extended slightly less far, as an underlying telescopic stage.
the ratios of the individual lifting means of one and the same telescopic lift can be designed differently, so that the respective higher telescopic stages are extended slightly less far, as an underlying telescopic stage.
the individual telescopic stages of a telescopic lifter are guided into each other by means of sliding guides.
This particularly economical embodiment of the telescopic lifter ensures a large-scale guidance of the respective telescopic stage and thus a reduction of the forces acting on the telescopic stage, so that also thereby a particularly economical embodiment of the underfloor lifting system is supported.
the design of the telescopic lifter can be carried out differently in adaptation to the respective intended lifting situation:
the lifting device can be used, for example, as a bogie lifter, so that the support elements lift, for example, a track bridge on which the relevant bogie is.
the telescopic lifter can be arranged comparatively far laterally next to the track or repair track in a conventional manner, so that there is a comparatively large cantilever arm between the telescopic column of the telescopic lifter and the support point at which the load is introduced into the support element.
the distance between the individual lifting means is also comparatively large, corresponding to the length of the cantilever.
the central drive between two lifting means of two telescopic stages may be arranged so that the driving force is transmitted uniformly to the two lifting means.
the lifting device can be used for example as Wagenkastenab 1. Since the car body has a greater width than the track of a rail vehicle and accordingly the car body receptacles are provided outside the track, in this case, the mentioned cantilever arm is comparatively short, so that advantageously the lifting means of two telescopic stages are arranged as close as possible adjacent to each other, too In this case, allow the lowest possible moments to act on the guides. Therefore, in this embodiment of the telescopic lifter advantageously the central drive for the lifting means on one side and beyond the two lifting means of two telescopic stages arranged, so that these two lifting means, for example, the aforementioned spindles, can be arranged in the smallest possible distance from each other.
the lifting means are to be arranged at a small distance from one another, they can advantageously be connected directly to one another by means of a coupling, for example by being fastened with their two ends to a respective shaft journal of a lifting means.
the two provided in this example shaft journals can thus almost touch, without additional, the distance-increasing intermediate elements are provided so that the horizontal offset between the two lifting means can be kept as low as possible.
the two lifting means can advantageously be connected to one another by means of a compensating coupling.
Compensation couplings are used to compensate for misalignment and / or angle errors and are commercially available.
the above-mentioned coupling which can serve for the direct connection of the two closely adjacent lifting means, can for example be designed as a compensating coupling. But even if additional, the distance-increasing intermediate elements between the lifting means are provided, may advantageously be provided a compensating coupling to avoid or reduce tension or vibration while the lifting means are driven.
the lifting means are arranged at a comparatively large distance from one another, they may advantageously be connected to one another in an advantageous manner by means of a propeller shaft as an alternative to the above-mentioned arrangement of a central drive between two lifting means, so that in this case the central drive for the lifting means on one side and beyond the two lifting means is arranged.
a propeller shaft as an alternative to the above-mentioned arrangement of a central drive between two lifting means, so that in this case the central drive for the lifting means on one side and beyond the two lifting means is arranged.
This allows a particularly economical embodiment of the underfloor lifting system, since it can be dispensed with a deflection or transfer case, which deflects or distributes the driving force in two different directions.
the choice of the drive shaft length with simple and economical means of the distance of the two lifting means can be adapted to a variety of requirements, for example, as regards the particular structural conditions or the location of the points to be supported in the vehicles to be lifted.
Fig. 1 is denoted by 1 in total an underfloor lifting system, wherein for foundation a pit 2 is provided and Fig. 1 a cross section through the pit 2 shows, looking in the track longitudinal direction.
a telescopic jack 3 is provided in each case, wherein in the longitudinal direction of the track behind each other at least two such telescopic lifter are provided.
Each telescopic jack 3 has three telescopic stages 4, 5 and 6, of which the two upper telescopic stages 5 and 6 are vertically movable, while the lower telescopic stage 4 is permanently installed.
the uppermost telescopic stage 6 has a support member 7 in the form of a cantilever, which at its remote from the telescopic stage 6, free end has a carrying point 8, at which the load is introduced into the support member 7 and thus in the entire telescopic lifter 3.
the telescopic lifter 3 are designed as a bogie jack so that the support member 7 has a comparatively long length and the support point 8 has a comparatively large distance from the telescopic column, for example, from the upper movable telescopic stage 6, to which the support member 7 connects.
two lifting means 9 and 10 are provided which are each designed as a spindle gear.
the lower lifting means 9 are used to move the lower movable telescopic stage 5, so the middle of the three telescopic stages, up and down, while the upper lifting means 10 allow the height mobility of the upper movable telescopic stage 6.
the lower lifting means 9 are arranged substantially below the carrying point 8, so that under the line of action of the load only low frictional forces between the individual telescopic stages 4, 5 and 6 arise, so that the leadership of the two movable telescopic stages 5 and 6 advantageously effective over a large area and economically available sliding guides 11 can be effected.
the drive for both lifting means 9 and 10 is centrally, with a transfer case 12 between the two lifting means 9 and 10 is arranged. From the transfer case 12, two short drive shafts 17 each extend to a stub shaft 16 of the lifting means 9 and 10th
a spindle 9-1 of the lower lifting means 9 is fixedly arranged, namely non-rotatable and not movable in height.
a nut 9-2 of the lower lifting means 9 selectively runs up or down, whereby this nut 9-2 is rotated by the transfer case 12. Accordingly, due to this movement of the nut 9-2, the transfer case 12 also changes in height with respect to the fixed spindle 9-1.
a second output of the transfer case 12 acts on a spindle 10-1 of the upper lifting means 10 and rotates this spindle 10-1 in rotation, which cooperates with a fixed, non-rotatable nut 10-2 of the upper lifting means 10.
the nut 10-2 is disposed in the upper movable telescopic stage 6, so that this telescopic stage 6 can be selectively moved upwards or downwards by means of the rotating spindle 10-1 of the upper lifting means 10 with respect to the transfer case 12 and its respective height position.
the gear ratio in the individual spindle gears is chosen so that at the same drive speed, from the transfer case 12, the lifting means 9 travel a greater distance than the lifting means 10, so that the upper movable telescopic stage 6 to a lesser extent from the lower movable telescopic stage. 5 is extended when the lower movable telescopic stage 5 is extended from the fixed lowermost telescopic stage 4.
the transfer case 12 designed such that at the same input speed, the two mentioned short drive shafts 17 of the transfer case 12 and thus also the stub shafts 16 of the both lifting means 9 and 10 run at the same speed, so that the lifting means 9 and 10 are driven at the same speed.
the different gear ratios of the lifting means 9 and 10 are effected by the slopes of the respective spindle gear. Deviating from the illustrated embodiment, however, can also be provided to make the two spindle gear of the lifting means 9 and 10 similar and to run the two short drive shafts 17 of the transfer case 12 at different speeds, so that the lifting means 9 are driven at a higher speed than the Lifting means 10.
Fig. 1 the two opposite telescopic lifter 3 are shown in different states: On the left, the telescopic lifter 3 is shown in its extended position, in which the support element 7 assumes its maximum achievable height. On the right, however, the telescopic jack 3 is shown in its retracted state, so that the support member 7 terminates at its upper edge level with the ground.
a repair track which is provided for example on the support elements 7, and runs above the support points 8, would thus be at floor level when the telescopic lift 3 as in Fig. 1 are shown lowered to the right.
Fig. 2 shows the two lifting means 9 and 10 and arranged therebetween transfer case 12 in an embodiment of a telescopic lifter 3 as based on Fig. 1 explained. It can be seen that the central drive 14 of the telescopic jack 3, an electric motor is provided which acts on the transfer case 12, which may be configured for example as bevel gear or as bevel gear.
Fig. 3 shows the drive elements of a telescopic lifter 3 in one embodiment as Wagenkastenab Stirr.
the parallel offset between the two lifting means 9 and 10 is significantly lower in this embodiment than in the embodiment according to Fig. 1 or 2 in which the telescopic lifter 3 are each designed as a bogie lifter.
the central drive 14 is arranged on one side beyond the two lifting means 9 and 10, so that accordingly no transfer case 12 is provided.
the electric motor of the central drive 14 may be configured as a gear motor, as in Fig. 3 is indicated with the gear 15 provided there.
the two lifting means 9 and 10 Due to the small distance between the lifting means 9 and 10 whose adjacent stub shafts 16 may be aligned substantially aligned with each other and directly without the interposition of gears, intermediate shafts or the like by means of a coupling, in particular a compensating coupling may be provided. Also in this case, the two lifting means 9 and 10 are driven at the same speed and have different gear ratios due to their different spindle pitches.
the stub shafts 16 of the two lifting means 9 and 10 are shown in all drawings, and the short drive shafts 17 of the transfer case 12 are in the Fig. 1 and 2 recognizable. Connecting elements such. B. the aforementioned compensating coupling are not shown, however, which serve to connect the stub shafts 16 with each other or with the short drive shafts 17.
