Abstract

A device for a distribution mast includes a line and a line section mounting. The line has a mast line section and a loose rotational line section, and the rotational line section is rotatably connected to the mast line section. The line section mounting has a loose rotational holding element and a rotary bearing, and the rotational holding element keeps the rotational line section at a distance from the mast line section. The rotary bearing is designed to be supported by a mast segment for the distribution mast and for rotatably connecting the rotational holding element to the mast segment and defines a circle, the line being guided through the circle.

First claim

The invention claimed is:

1. A device for a distribution mast, comprising:
a line having a mast line portion and a loose rotating line portion, the rotating line portion being rotatably connected to the mast line portion; and
a line portion mounting having a loose rotating holding element and a rotary bearing, wherein:
the rotating holding element holds the rotating line portion se as to be remote from the mast line portion,
the rotary bearing is configured to be mounted by a mast segment of the distribution mast and for rotatably connecting the rotating holding element to the mast segment and defines a circle, wherein the line runs through the circle,
the rotating line portion is connected in a continuously rotating manner to the mast line portion,
the rotary bearing is configured for connecting the rotating holding element to the mast segment in a continuously rotating manner, and
the device is configured in such a manner that, when the rotary bearing is mounted by the mast segment, a continuous rotation of the rotating holding element having the rotating line portion is unrestricted by the mast segment and the mast line portion.

2. The device according to claim 1 ,
wherein the rotating line portion is connected to the mast line portion so as to be rotatable about a rotation axis, and
wherein the device for disposing the rotation axis is configured so as not to be parallel to a longitudinal axis of the mast segment.

3. The device according to claim 1 ,
wherein the rotating line portion is connected to the mast line portion so as to be rotatable about a rotation axis, and
wherein the rotary bearing is configured for connecting to the mast segment so as to be rotatable about the rotation axis of the rotating holding element.

4. The device according to claim 1 , wherein at least one of:
(i) the mast line portion has a mast bend, the mast bend being rotatably connected to the rotating line portion and/or running through the circle; or
(ii) the rotating line portion has a rotating bend, the rotating bend being rotatably connected to the mast line portion, and/or running through the circle, and/or the rotating holding element holds the rotating line portion on an end of the rotating bend that is remote from the mast line portion.

5. The device according to claim 4 ,
wherein the rotating bend is connected to the mast bend so as to be rotatable about a rotation axis,
wherein the rotating bend and the mast bend along the rotation axis delimit an internal region; and
wherein at least one of: (i) a bearing point of the rotary bearing and/or a circle center point of the circle are/is disposed in the internal region, or (ii) the rotating holding element runs from the rotary bearing to the rotating line portion in the internal region.

6. The device according to claim 1 , further comprising:
a hose coupling, wherein the hose coupling is configured for connecting the rotating line portion to a hose and wherein the rotating holding element holds the rotating line portion on the hose coupling; and/or
wherein the rotating line portion comprises the hose, wherein the rotating holding element holds the hose remote from the mast line portion.

7. The device according to claim 1 ,
wherein the line is a conveying line.

8. The device according to claim 1 ,
wherein the line is a construction material conveying line.

9. The device according to claim 1 ,
wherein the line is a thick matter conveying line.

10. The device according to claim 1 ,
wherein the rotary bearing is a four-point bearing.

11. The device according to claim 1 ,
wherein the line portion mounting has a rotary flange,
wherein the rotary flange is configured to be mounted by the mast segment and comprises the rotary bearing, and
wherein the line runs through the rotary flange.

12. The device according to claim 1 ,
wherein the device is configured for disposing the mast line portion and the rotating line portion on a same side of the mast segment, with the rotating line portion being more remote from the mast segment than the mast line portion.

13. The device according to claim 1 , further comprising:
the mast segment, wherein the mast segment holds the rotary bearing.

14. A distribution mast, comprising:
a device according to claim 13 ; and
further mast segments;
wherein the mast segment and the further mast segments are connected to one another so as to be able to be folded.

15. The distribution mast according to claim 14 , wherein the mast segment and the further mast segments are foldable in a rolling Z-shaped manner.

16. A system, comprising:
a distribution mast according to claim 14 ; and
a construction material pump, wherein the construction material pump is configured for conveying construction material through the line.

17. The system according to claim 16 , wherein the construction material pump is a thick matter pump.

18. A device for a distribution mast, comprising:
a line having a mast line portion and a loose rotating line portion, the rotating line portion being rotatably connected to the mast line portion;
a line portion mounting having a loose rotating holding element and a rotary bearing,
a rotary coupling which is different from the rotating holding element and the rotary bearing, wherein the rotating holding element holds the rotating line portion remote from the mast line portion,
the rotary bearing is configured to be mounted by a mast segment of the distribution mast and for rotatably connecting the rotating holding element to the mast segment and defines a circle, wherein the line runs through the circle,
the rotary coupling rotatably connects the rotating line portion to the mast line portion, and the rotary coupling is coaxial with the rotary bearing.
