Description
[0033] The invention will be further explained with the aid of the figures. In the following:
[0034] FIG. 1 shows a modular heavy-duty vehicle with a pipe in a side view,
[0035] FIG. 2 shows a sectional view of FIG. 1,
[0036] FIG. 3 shows a perspective view of two pipe securing systems on a load area of a heavy-duty vehicle,
[0037] FIG. 4 shows a semi-oblique view of two pipe securing systems on a load area of a heavy-duty vehicle,
[0038] FIG. 5 shows a semi-oblique view of two pipe securing systems with a pipe laid in position,
[0039] FIG. 6a and FIG. 6b show a lateral view of two pipe securing systems with and without a lifting device, with a pipe laid in position,
[0040] FIG. 7 shows a rear view of a heavy-duty vehicle with a pipe securing system, and
[0041] FIG. 8 shows a rear view of a heavy-duty vehicle with a pipe securing system and a pipe laid in position.
[0042] FIG. 1 shows a pipe 40 for a wind turbine, which pipe is also referred to as a monopile, made of multiple pipe sections 44 that are welded together. The pipe 40 lies on two turning devices 42 which are respectively positioned in the region of the pipe ends. A modular heavy-duty vehicle 30 is positioned under the middle region of the pipe 40. Multiple support beams 2 are arranged on the load area 31. In accordance with the prior art, the pipe is placed and supported on the support beams after the lowering of the pipe or raising of the load area of the heavy-duty vehicle.
[0043] FIG. 2 shows a sectional view of FIG. 1 along the section line A-A. The pipe wall 41 lies on two rollers 43 of the turning device 42. A support beam 2 is arranged on the load area of the modular heavy-duty vehicle 30. A clearance C can be seen between the pipe wall 41 and the top side of the support beam 2. The heavy-duty vehicle 30 is multi-axial and has a plurality of tires 32.
[0044] FIG. 3 shows a detail from a load area 31 of a modular heavy-duty vehicle 30. The heavy-duty vehicle is assembled from multiple modules 30a. Two pipe securing systems 1 are positioned on the load area 31. The left-hand pipe securing system 1 is in the empty state, and the right-hand pipe securing system 1 is in the operating state. In the empty state, a bearing shell 3a is positioned next to a cross-beam 2a. The bearing shell 3a comprises on the bottom side thereof a pedestal surface 4 which stands on the load area 31. On the top side, the bearing shell comprises a recess 5, the curvature of which corresponds to the curvature of the pipe wall, in order to be able to accommodate the pipe. On both transverse sides 6 of the bearing shell, one load handling means 7 each is attached in the form of a metal profile. One lifting device 8 each is arranged beneath the load handling means 7. In the middle, the lifting device has a seat 9 for the load handling means 7 in the form of a plate. The lifting device 8, in this case a jack, comprises rollers 10 on its four corners. The right-hand pipe securing system is shown in the operating state. A bearing shell 3b is arranged on the support beam 2b. The pedestal surface 4 of the bearing shell 3b stands on the support beam 2b. The lateral load handling means 7 respectively lie on the two lifting devices 8 that have been rolled next to the support beam 2b.
[0045] FIG. 4 likewise shows, in a semi-oblique view, two pipe securing systems on the load area 31 of a modular heavy-duty vehicle 30. The lifting devices have not been included in the illustration for either pipe securing system. The left-hand pipe securing system 1 is in the empty state, and the right-hand pipe securing system 1 is in the operating state. In the left-hand pipe securing system, a bearing shell 3 is positioned next to the cross-beam 2 in the empty state. The bearing shell 3 comprises a recess 5 on the top side. The higher side regions 11 of the bearing shell next to the recess have the same height as the support beam 2. On both transverse sides 6 of the bearing shell, one load handling means 7 each is attached in the form of a metal profile, the top side of which in this case likewise corresponds to the top side of the non-channeled side regions 11. The right-hand pipe securing system is shown in the operating state. The bearing shell stands on the support beam 2. The pedestal surface 4 of the bearing shell 3 stands on the support beam 2.
[0046] FIG. 5 shows the two pipe securing systems from FIG. 4 in the same perspective, but with a pipe. The right-hand pipe securing system in the operating state carries the pipe, which lies in the recess 5 of the bearing shell 3. In the left-hand pipe securing system in the empty state, the clearance C between the pipe wall and the support beam 2 can be seen.
[0047] In FIGS. 6a and 6b, a side view of two pipe securing systems in the operating state and in the empty state are shown. In FIG. 6a, the pipe securing systems are illustrated without lifting devices. In the left-hand pipe securing system, the bearing shell 3 stands next to the support beam 2 on the load area 31. The bearing shell has the same height as the support beam. In the right-hand pipe securing system in the operating state, the bearing shell 3 is on the support beam 2 and the pipe 40 lies in the bearing shell. The pipe 40 is only shown here as a detail. In FIG. 6b, the pipe 40 is also only shown as a detail. In addition, the lifting devices 8 are shown in FIG. 6b. In the left-hand pipe securing system, the lifting device 8 is folded together next to the bearing shell 3. In the right-hand pipe securing system, the lifting device 8 is positioned next to the cross-beam 2, and the load handling means 7 of the bearing shell is still lying on the lifting device 8.
[0048] FIG. 7 shows a pipe securing system in a rear view, without a pipe laid in position. The bearing shell 3 stands on the support beam 2, which in turn stands on the load area 31 of the heavy-duty vehicle. In the center region, the bearing shell 3 comprises a recess 5, whereas the two side regions 11 are elevated. The load handling means 7 are affixed on the transverse sides. FIG. 8 shows the same view as FIG. 7, with a pipe 40 that lies in the bearing shell 3 being additionally shown as a detail. Due to the curvature of the bearing shell in the region of the recess, the pipe is both secured against a rolling-away and protected against mechanical damage.
[0049] Both from FIG. 5 and from FIGS. 6 and 7, it can be seen that the clearance between the support beam and pipe is only very low, and that it is therefore difficult to place a securing mechanism for the pipe under the pipe or in the pipe shadow. This problem is solved with the bearing shell, which can be moved in the tight space and is slid onto the support beam under the pipe by means of the lifting device.
[0050] The invention is not limited to any one of the embodiments described above, but rather can be modified in many and varied ways.
[0051] All features and advantages arising from the claims, the specification, and the drawings, including constructive details, spatial arrangements, and method steps, can be essential to the invention both separately and also in the most widely different combinations.
