Abstract

The present invention relates to a milling unit, in particular to a milling unit of a road milling machine, a transport vehicle with a transport device and a vehicle, as well as a method for transporting a milling unit, in particular using a transport vehicle according to the present invention.

First claim

What is claimed is:

1. In combination, a transport device and a milling unit of a road milling machine including a milling drum box and milling drum arranged inside the milling drum box, the transport device comprising:
a support frame;
a support skid configured to support the milling unit, the support skid being arranged on the support frame in a displaceable manner in a horizontal plane and comprising a milling unit receptacle designed in a shape adapted to the milling unit;
a drive device configured to drive displacement movement of the support skid relative to the support frame; and
a transport vehicle connector configured to be coupled to a carrier vehicle,
wherein the transport device is configured to be lifted and lowered relative to the ground via coupling of the transport vehicle connector to the carrier vehicle.

2. The combination according to claim 1 ,
wherein the support frame comprises at least one of the following features:
the support frame forms a bottom structure of the transport device;
the support frame is configured as essentially rectangular;
the support frame comprises at least one longitudinal and/or at least one transverse strut; and
the support frame comprises at least one ground roll.

3. The combination according to claim 1 ,
wherein a guiding device is arranged on the support frame which is configured such that the guiding device guides the support skid along a movement track.

4. The combination according to claim 3 ,
wherein the guiding device comprises at least one of the following features:
the guiding device comprises at least one guiding rail on which a rolling device runs;
the guiding device comprises a guiding slot in which a rolling device runs;
the guiding device comprises a switch via which various guiding tracks may be linked; and
the guiding device comprises at least one extension element, with which the guiding track may be extended beyond the support frame.

5. The combination according to claim 1 ,
wherein the support skid comprises rolls with which the support skid rests on the support frame.

6. The combination according to claim 1 ,
wherein the support skid comprises a milling unit receptacle.

7. The combination according to claim 6 ,
wherein the milling unit receptacle comprises at least one of the following features:
the milling unit receptacle comprises a support tray which is upwardly open;
the milling unit receptacle comprises at least one support beam; and
the milling unit receptacle comprises a displacement lock.

8. The combination according to claim 1 ,
wherein a rotating device is provided which is configured such that the support skid can be rotated about a vertical axis relative to the support frame.

9. The combination according to claim 1 ,
wherein the transport vehicle connector is configured in a manner of a rotary joint.

10. The combination according to claim 1 ,
wherein a locking device is provided with which the support skid can be locked in at least one position relative to the support frame.

11. The combination according to claim 1 ,
wherein at least one drive-on ramp is provided.

12. The combination according to claim 1 ,
wherein a swell-bridging structure is provided between two rail-type swells.

13. A combination comprising the combination of claim 1 and a transport vehicle, the transport vehicle comprising a carrier vehicle including a loading arm which is detachably connectable to the transport device for the milling unit and can be adjusted on the carrier vehicle between a transport position and a loading position, wherein the transport device can be loaded onto and unloaded from the carrier vehicle using the loading arm.

14. The combination according to claim 1 ,
wherein the carrier vehicle comprises a swap body vehicle.

15. A method for transporting a milling unit using the combination according to claim 14 , comprising the steps of:
a) loading the milling unit from a road milling machine onto the support skid of the transport device;
b) displacing the support skid relative to the support frame;
c) loading the transport device together with the milling unit onto the carrier vehicle;
and/or
d) delivering the milling unit with the transport vehicle;
e) unloading the transport device from the carrier vehicle;
f) displacing the milling unit relative to the support frame of the transport device using a support skid; and
g) fastening the milling unit to the road milling machine.

16. The method according to claim 15 ,
wherein in step a) loading is effected by lowering the milling unit onto the support skid.

17. The method according to claim 5 ,
wherein in the course of steps a) to c) and/or d) to g) the support skid is displaced between an essentially central transport position and a mounting position and/or a milling machine maneuvering position.

18. The method according to claim 15 ,
wherein, prior to step c), the support skid is locked in a transport position, and prior to step f), the locked support skid is unlocked.

19. The method according to claim 15 ,
wherein, prior to step f), the milling unit is rotated via a rotating device of the transport device.

20. The method according to claim 15 ,
wherein, between steps e) and g), the road milling machine at least partially travels over the transport device.
