Definitions
- An exemplary task here is to carry out the work in sections of 2 bridges per lockout with the shortest possible construction time, with old bridge structures to be exchanged with approx. 70 t steel superstructures each, which are to be replaced by new bridges, each with approx. 320 t of reinforced concrete are made.
- a targeted construction time for the execution is, for example, around 34 hours per structure, during which time the crane would have to be brought into position and the lift carried out.
- the laid-open specification DE 100 04 194 A1 discloses a method for manufacturing a fixed rail track on a bridge.
- steps are disclosed how the concreting of such a bridge can be designed advantageously especially for use as a railroad track.
- this publication does not offer any suggestions for replacing a bridge in track systems.
- the structural measure is carried out by means of a boiler or high bridge, which is used in combination with an SPMT (Self-Propelled-Modular-Trailer).
- the SPMT is able to carry out the maneuvers longitudinal travel, transverse travel, diagonal travel or circular travel, which can be called up fully electronically via the remote control.
- a special lifting system comprising a steel structure to accommodate the lifting system in the boiler or high bridge.
- the new development includes a parallel rope combination with suspension heads on both sides with an integrated rope pulley for the load bearing, in an advantageous version with 5 grooves for a load bearing of 150 t plus the resulting force from the lifting strands.
- Another element relevant to the installation of the bridge structure is a hydraulic lateral displacement option for positioning the bridge in its installation end position, whereby the required longitudinal displacement can be carried out via the hydrostatic drive of the SPMT.
- the suspension on the bridge has suspension heads on the bridge structure itself, each in connection with the static requirements and possibilities of the structure are coordinated.
- the high girder bridge and the lifting system can be positioned lengthways and crossways so that the bridge structure can be lifted directly over the abutments on the structure. This has the advantage that no other bending moment arises in the structure compared to the state in the end position.
- the task is to replace a total of 8 bridges in the course of a 60-day schedule.
- a construction company provides a drivable area
- the bridge to be exchanged picks it up with the lifting technology described, sets through across drives to the neighboring track and can thus drive out the old bridge.
- the bridge is lowered to any height using the newly developed lifting technology and placed on the abutments. If required, the sideshift can be carried out, which is provided via a double piston cylinder.
- the number of SPMT axle lines can be selected so that a comparison can be made with the load scheme of, for example, Deutsche Bahn for locomotives or freight trains can be created.
- the load scheme for example, Deutsche Bahn for locomotives or freight trains.
- the old bridge to be replaced is loosened from the track system in reverse order.
- auxiliary bridge (HB) is temporarily used to cross the open gap after the old bridge has been removed. In the case of single-track lines, this can be done by entering the HB with SPMT or lifting it in with a mobile crane. If this happens with an SPMT, it can remain under the HB as support. In this way, the rail wagon can drive over the auxiliary bridge and lower the new bridge structure in a precisely positioned manner, as has already been described in more detail.
- Show it 1 shows a plan view of the high bridge (11) used on a track system (7) with a bridge structure (3) to be lifted;
- FIG. 2 shows a side view of the high bridge (11) according to the invention, mounted on SPMTs (8) with a suspended bridge structure (3);
- FIG. 3 shows a combination of views of the lifting device according to the invention in the retracted state for lifting a load
- the lifting device according to the invention drive out to lower a load
- FIG. 5 shows the section AA through the high bridge (11) with the suspended bridge structure (3) and the lifting device arranged therein;
- Figure 6 is a side view of an alternative
- Fig. 7 The device of Figure 6 during the installation process of a new bridge structure (3).
- FIG. 1 the device 1 according to the invention for removing an old bridge structure and for installing a new bridge structure 3 is shown in plan view.
- the arrows 19 here show that due to the SPMTs 8 serving as the chassis, a transverse travel 6 to the track system 7 is also possible in order to be able to pick up the bridge structure parked parallel to the tracks.
- FIG. 1 It can also be seen in FIG. 1 that special lifting devices 2 are provided on the high bridge 11, which are arranged to run in the longitudinal direction of the high bridge 11.
- the hydraulic component as can be seen and explained in more detail in FIGS. 3 and 4, is shown in the extended state. This is the case when the lifting device unloads or picks up a load before the load is lifted.
- the device for height adjustment 10 of the high bridge 11 is raised exactly so that a safety distance to the overhead line 9 is guaranteed.
- the old bridge structure has already been removed from the track system 7, and the device 1 with the high bridge 11 suspended new bridge structure 3 has been moved into position so that the new bridge structure 3 can be lowered to any height using the lifting technology according to the invention, as can be seen from the lower position of the bridge structure 3.
- the new bridge can be placed exactly on bridge abutments that may have been built for the new bridge structure after the old bridge was removed.
- FIG. 3 now shows the Hubvor device 2 according to the invention only in the retracted state.
- FIG. 4 shows the lifting device in the extended state, which is why the suspension head 15 has now shifted towards the pulley 13 and thus the parallel cables 17 guided over the pulley 13 are lowered downwards.
- This advantageous and innovative construction makes it possible to effect the lifting movement by deflecting the parallel ropes 17 via the pulley 13 without increasing the device via a hydraulic cylinder in the direction of the lifting movement, namely vertical.
- the hydraulic movement takes place only ho rizontal and thus causes no negative change in height of the device 1, which would cause problems with the overhead line 9 be.
- FIGS. 6 and 7 again show lateral views of the device 1, the difference here being that the trolleys are not designed as SPMTs, but the high bridge 11 is arranged on two railroad cars, for example on support wagons.
- this auxiliary bridge is mounted on SPMTs, which also cause the auxiliary bridge to be supported when the device itself passes over the auxiliary bridge.
