Description
Device for Transporting Long Welded Rails
Field of technology
[01] The invention relates to a device for the transport of long-welded
rails by
means of a rail loading train, including an installation for secured storage
of
the rails.
Prior art
[02] Various known rail loading trains serve for picking up or laying rails
of a
track section by means of a gantry crane in a train formation. To that end,
the gantry crane is mobile in a longitudinal direction of the track by
means of separate undercarriages on crane rails which are mounted at
both sides on the rail loading train. During transport travel, the rails must
be securely stored and anchored on the rail loading train.
[03] Known according to DE 20 2005 019 061 U1 and DE 20 2009 006 549 Ul
is a respective rail loading train for the transport of long-welded rails,
with
installations arranged on the rail loading train for storing and anchoring
the rails.
Summary of the invention
[04] It is the object of the invention to show an improvement over the
prior art for
a device of the type mentioned at the beginning for the transport of long-
welded rails.
[05] According to the invention, this object is achieved by way of a device
for the
transport of long-welded rails according to claim 1. Dependent claims
indicate advantageous embodiments of the invention.
[06] The invention provides that the device is designed as a modular unit
having
fastening means for anchoring on a container flat wagon and comprises a
separate energy supply unit. A modular unit of this kind can be employed
flexibly, wherein a rail loading train can be assembled from container flat
wagons and one modular unit or several modular units. By means of the
CA 03061683 2019-10-28
2
fastening means, the modular unit is anchored simply and securely at the
existing support points for standard containers. The entire rail loading train
can thus be adapted perfectly and cost-effectively to prevailing conditions by
an operator, wherein already-existing container flat wagons can be used.
[07] In this, it is useful if the fastening means are arranged on a module
frame,
and if the installation for guiding and/or locking the rails is fastened to
the
module frame. The module frame offers a structurally simple solution for
securely fastening the installation for guiding and/or locking the rails.
[08] In an advantageous embodiment of the invention, the energy supply unit
comprises a hydraulic unit, and the installation comprises hydraulic drives.
The hydraulic unit and the hydraulic drives ensure a flexible adjustment to
structural space conditions and achieve great positioning precision.
[09] In this, it is favourable if the energy supply unit comprises a
combustion
engine and a tank container. By means of the combustion engine and the
tank container, the modular unit is operated independently and energy self-
sufficiently.
[10] A continuing variant provides that the energy supply unit comprises an
electric machine and an electric energy store. By means of the electric
machine (generator or motor) and the energy store, the modular unit can be
operated in an emission-free manner, if required.
[11] Additionally it is advantageous if a sleeve, designed to be pushed
onto a
container mandrel of the container flat wagon, is arranged as fastening
means. By this, the modular unit is fastened in a simple manner at the
support points for standard containers.
[12] Another continuing variant provides that a clamping device is arranged
as
fastening means which is designed to be pushed onto a socket provided for a
container mandrel on the container flat wagon. The clamping device can
absorb greater forces than the container mandrel.
[13] A further advantageous embodiment of the invention provides that the
energy
supply unit has a connection for energy supply of a further modular unit
situated on the container flat wagon. Thus, several modular units situated on
a container flat wagon can be operated with a common energy supply unit.

[14] Advantageously, the installation comprises a pivot beam. The pivot
beam
serves as support bracket for the long-welded rails. Its pivot arms can be
pivoted for loading and unloading procedures.
[15] It is further advantageous if the installation comprises a rail
clamping unit.
With this, the rails are anchored securely in order to avoid any sliding
during
transport travel.
[16] A further advantageous embodiment of the invention provides that the
installation comprises a rail impact wall. The rail impact wall constitutes an
additional safety installation of the rail loading train and prevents, for
example, the rails from sliding in the direction of a driver's cabin in case
of
emergency braking.
[17] Additionally it is advantageous that the modular unit comprises a
crane buffer
for a gantry crane. By means of the crane buffers arranged in each case at
the ends of the rail loading train, a derailing of the gantry crane is
reliably
counteracted.
[18] In an improved embodiment of the invention, the modular unit in a
horizontal projection has dimensions and anchorings of a 20' container. With
this, the modular unit is fastened at the support points of a 20' standard
container.
[19] Another variant provides that the modular unit in a horizontal
projection has
dimensions and anchorings of a 30' container. With this, the modular unit is
fastened at the support points of a 30' standard container.

Description of the embodiments
[28] Fig. 1 shows a view of a container flat wagon 2, mobile by means of on-
track
undercarriages 1, on which devices for the transport of long-welded rails 3
are arranged. Several such container flat wagons are coupled together to
form a rail loading train. The devices are designed in each case as a modular
unit 3 which is anchored by means of fastening means 5 on a base frame 6
of the container float wagon 2. The modular unit 3 comprises a module frame
7, preferably formed by steel beams, on which an installation 8 for guiding
and/or locking the rails 4 is arranged. Furthermore, an energy supply unit 9
is
associated with the modular unit 3. Mounted laterally at either side of the
container flat wagon 2 is a crane rail 10 for a gantry crane mobile in the
longitudinal direction 11 of the track. The crane rail 10 is either fixedly
arranged or laterally displaceable.
[29] Fig. 2 shows the schematically depicted energy supply unit 9. The
latter is
arranged in a space-saving manner within the module frame 7. The energy
supply unit 9 comprises, for example, a hydraulic unit. Arranged as a drive in
the energy supply unit 9 is a combustion engine with tank container, an
electric machine with electric energy store, or a hybrid drive.
[30] Shown in Fig. 3 is a detail view of the modular unit 3 with closed
pivot beam
12. The pivot beam 12 is arranged laterally on longitudinal beams 13 of the
module frame 7. For a loading- or unloading operation, a pivot beam arm 15
is pivoted outward in each case about a vertical axis 16 via a pivot beam
joint
14. Each modular unit 3 has lifting lugs 17 in order to load the required
modular unit 3 on the container flat wagon 2 by means of a crane.
[31] In Fig. 4, the modular unit 3 is equipped with pivot beams 12, crane
buffers
18 and a rail impact wall 19. All installations 8 are fastened laterally at
the
longitudinal beams 13 of the module frame 7. Like the pivot beam 12, the rail
impact wall 19 is designed to be pivotable about a vertical axis 16 for
loading
and unloading the rail loading train with rails 4. The rail impact wall 19 and
pivot beam 12 have separate hydraulic drives 20 in each case which are
CA 03061683 2019-10-28

operated via the energy supply unit 9. The crane buffer 18 ensures secure
containment of the gantry crane.
[32] Fig. 5 shows a further variant of the modular unit 3 with a rail
clamping unit
21. The latter is likewise fastened to the longitudinal beams 13 of the module
frame 7 and comprises supports 22 to counteract the enormous longitudinal
forces during braking- and starting procedures. The fastening means 5 are
arranged underneath on the module frame 7. The rail clamping unit 21 also
has a hydraulic drive 20.
[33] Shown in Fig. 6 is a variant of a support point 23 for standard
containers. A
fold-away container mandrel 24 is arranged in a socket 25 on a base frame
26 of the container flat wagon 2. The fastening means 5 located in the
module frame 7 comprises a sleeve 27 (Fig. 3) and is simply pushed over the
container mandrel 24 and then locked with a safety catch.
[34] Fig. 7 shows a variant of embodiment of the fastening means 5 which is
represented here without the module frame 7 connected thereto. The
fastening means 5 is designed in this case as a clamping device 28. With this
it is possible to transmit great forces. This is advantageous particularly for
a
modular unit 3 with a rail clamping unit 21 arranged thereon. This is because
very great inertial forces of the rails 4 act upon the rail clamping unit 21
during starting and braking of the rail loading train. The tilting moments
generated in the process have to be absorbed by the fastening means 5. The
clamping device 28 is mounted in place of the container mandrel 24. A
delimiting by means of the socket 25 safeguards the clamping device 28
additionally against lateral sliding. Moreover, a claw 29 grips a frame edge
30
of the container flat wagon 2, by which a tilting of the modular unit 3 is
reliably avoided. For mounting the modular unit 3 on the container flat wagon
2, the claw 29 is arranged detachably on a base member 31 of the clamping
device 29. To that end, screw connections 32 are provided, for example.
