Abstract

The present invention relates to a self-propelled ground milling machine, comprising a drive engine arranged in an engine compartment and an engine compartment enclosure which covers the engine compartment at least partly to the sides and to the top. A part of the engine compartment enclosure is a cover which is adjustable between a covering position and a maintenance position. At the same time, a maintenance platform is provided which is movable between a stowage position and a maintenance position. When the maintenance platform is in the maintenance position, an operator standing on the floor surface of the maintenance platform can carry out maintenance work in the engine compartment of the self-propelled ground milling machine. The self-propelled ground milling machine preferably is a road milling machine, more particularly a large milling machine, a surface miner, a stabilizer or a recycler.

First claim

What is claimed is:

1 . A self-propelled ground milling machine, comprising:
a drive engine arranged in an engine compartment and an engine compartment enclosure which covers the engine compartment at least partly to the sides and to the top, at least a part of the engine compartment enclosure being a cover which is adjustable between a covering position and a maintenance position, wherein a movable maintenance platform is provided which is mounted on the ground milling machine so as to be able to move between a stowage position and a maintenance position, the maintenance platform comprising a floor surface for an operator from which said operator can carry out maintenance work in the engine compartment, and the maintenance platform being adjustable together with the cover in such a manner that an adjustment of the maintenance platform to the maintenance position occurs with the adjustment of the cover to the maintenance position, and an adjustment of the maintenance platform to the stowage position occurs with the adjustment of the cover to the covering position.

2 . The self-propelled ground milling machine according to claim 1 ,
wherein the cover is at least partly a part of a side paneling of the engine compartment enclosure.

3 . The self-propelled ground milling machine according to claim 1 ,
wherein the cover comprises a side paneling element and a top side paneling element.

4 . The self-propelled ground milling machine according to claim 1 ,
wherein the cover and/or the maintenance platform are mounted on the ground milling machine so as to be able to swivel between the covering position and/or the stowage position and the respective maintenance position.

5 . The self-propelled ground milling machine according to claim 1 ,
wherein the cover and the maintenance platform can swivel about a common swivel axis.

6 . The self-propelled ground milling machine according to claim 1 ,
wherein the cover and the maintenance platform can respectively swivel about a separate swivel axis, the two swivel axes extending parallel to each other.

7 . The self-propelled ground milling machine according to claim 1 ,
wherein the cover and/or the maintenance platform are mounted on the ground milling machine so as to be linearly displaceable between the covering position and/or the stowage position and the respective maintenance position.

8 . The self-propelled ground milling machine according to claim 1 ,
wherein the maintenance platform is covered at least partly to the outside in the stowage position by the cover situated in the stowage position.

9 . The self-propelled ground milling machine according to claim 1 ,
wherein the maintenance platform is part of the cover with its exterior side and thus part of the engine compartment enclosure.

10 . The self-propelled ground milling machine according to claim 1 ,
wherein the maintenance platform comprises a railing which protrudes in an upright manner essentially perpendicularly therefrom.

11 . The self-propelled ground milling machine according to claim 10 ,
wherein the railing is fixedly connected to the maintenance platform.

12 . The self-propelled ground milling machine according to claim 10 ,
wherein the railing is connected to the maintenance platform so as to be able to swivel, from an upright fall protection position to a stowage position resting flat on the floor surface of the maintenance platform.

13 . The self-propelled ground milling machine according to claim 12 ,
wherein the swiveling railing is a fall protection for a free space between a side wall of the ground milling machine and a rear wall formed by the cover situated in the maintenance position.

14 . The self-propelled ground milling machine according to claim 10 ,
wherein the maintenance platform and the railing form a maintenance balcony which protrudes to the side of the ground milling machine and is accessible from the side in the maintenance position.

15 . The self-propelled ground milling machine according to claim 1 ,
wherein the maintenance platform and the cover are connected to each other via a guide device which is formed for the transfer of motion between the cover and the maintenance platform.

16 . The self-propelled ground milling machine according to claim 15 ,
wherein the guide device is an adjustable connecting strut, a cylinder-piston unit or a pin guided in a slideway.

17 . The self-propelled ground milling machine according to claim 1 ,
wherein the adjusting movement of the maintenance platform and/or the cover between the end positions is driven by a drive device.

18 . The self-propelled ground milling machine according to claim 1 ,
wherein a latching device is provided which is implemented in such a manner that it fixes the maintenance platform and/or the cover in the maintenance position.

19 . The self-propelled ground milling machine according to claim 1 ,
wherein it is a self-propelled ground milling machine, comprising an operator platform and a milling drum arranged on a machine frame.

20 . The self-propelled ground milling machine according to claim 19 ,
wherein the maintenance platform and the cover are articulated to the machine frame of the self-propelled ground milling machine.

21 . The self-propelled ground milling machine according to claim 19 ,
wherein a laterally protruding transfer plate is provided via which the operator reaches the maintenance platform situated in the maintenance position from the operator platform.

22 . The self-propelled ground milling machine according to claim 19 ,
wherein the maintenance platform is arranged on the self-propelled ground milling machine in such a manner that in the maintenance position it is situated essentially at the level of the floor surface of the operator platform.

23 . The self-propelled ground milling machine according to claim 19 ,
wherein the maintenance platform is arranged in the working direction (a) of the self-propelled ground milling machine behind the operator platform.

24 . The self-propelled ground milling machine according to claim 19 ,
wherein the operator platform ( 6 ) of the self-propelled ground milling machine comprises a roof ( 32 ) which can be swiveled between a working position and a transport position, the roof ( 32 ) being able to be swiveled forwardly in the working direction from the working position to the transport position.
