Description

MOBILE HALL CONSTRUCTION

The present invention relates to a mobile hall construction, more particularly for carrying out maintenance and/or repair work on a turbine rotor, comprising at least one base frame, a plurality of support pillars which are held on the at least one base frame, and a roof structure which can be mounted on the support pillars.

Maintenance and/or repair works on a turbine rotor are advantageously carried out whilst the rotor is located in a vertical position. In particular the unstacking of a turbine rotor is considerably simplified in this way. In order to erect rotors with a high inherent weight, rotor pivot systems are used in the prior art. These comprise a turning block with a pivot mechanism mounted thereon, and at least one bearing block. The turning block and the bearing block are set up in a first step on an industrial hall floor and aligned relative to one another wherein at least the turning block is anchored on the hall floor by suitable fastening means. The rotor which is to be processed is then in a further step by using a crane placed on the turning block and the bearing block and then fixed on the pivot mechanism which is provided on the turning block. The rotor can now by utilizing the pivot mechanism and using a crane be moved into the vertical position and locked here in order to carry out the ensuing maintenance and/or repair work on the upright rotor.

One problem during the maintenance and/or repair work on turbine rotors lies in the fact that their use requires industrial peripherals in the form of a hall with industrially made foundations on which the turning block and

PCT/EP2 015/066639 2014P14960WOAU 2 the at least one bearing block are arranged and into which the forces can be introduced via the turning block when erecting the rotor. Industrial halls with corresponding foundations are in many places not available however because they have to be erected which involves very high costs. Alternatively mobile hall constructions of the type mentioned at the beginning can be used which are set up on an industrial foundation prior to carrying out the work, and are dismantled again once the work has been completed. A problem arises here in this connection that for very long turbine rotors the mobile hall constructions have to have very great heights for their maintenance and/or repair, which requires the use of high cranes for setting up and dismantling the mobile hall constructions, and these high cranes are likewise not available at many locations.

Starting from this prior art the object of the present invention is to provide a mobile hall construction of the type mentioned at the beginning which despite the great height can be erected and dismantled by using conventional small cranes.

To achieve this, the present invention provides a mobile hall construction of the type mentioned at the beginning which is characterized in that the support pillars are provided with at least one drive and are articulatedly mounted on the at least one base frame in such a way that with the use of at least one drive, they can be pivoted between a transport position and a straightened-up position relative to the at least one base frame. As a result of this configuration the support pillars of the mobile hall construction according to the invention can be straightened up independently which can dispense with the use of high cranes.

Each support pillar is preferably held on a separate base frame. A modular structure is hereby achieved

PCT/EP2015/066639 2014P14960WOAU 3 with which the individual base frames can be easily transported and handled.

The dimensions of the base frames are advantageously selected so that these frames can be transported in containers which have standardized dimensions. The transport of the mobile construction accordingly represents no problem whether by air, sea or land.

The base frames and/or the containers with the base frames arranged therein are preferably designed to be connectable with one another so that the rigidity of the construction can be increased if this is required.

The at least one drive is advantageously provided as a hydraulic drive, more particularly as at least a hydraulic cylinder which can be articulatedly connected both with the at least one base frame and also with one of the support pillars. This leads to a simple technical implementation when automatically straightening the support pillars.

According to one configuration of the present invention each support pillar is provided with its own drive wherein the drives can advantageously be moved simultaneously by using suitable software.

The roof structure is preferably connected for articulation with the support pillars. This is advantageous so that the roof structure can be mounted in that position in which the support pillars are located in their transport position, and then pivoted together with the support pillars. The mounting of the roof structure can take place accordingly at a low level whereby time, costs and the risks of danger to personnel can be reduced.

PCT/EP2 015/066639 2014P14960WOAU 3a

The roof structure preferably has at least one loading crane. In other words at least one loading crane is integrated in the roof structure so that no separate loading crane has to be installed

PCT/EP2015/066639 2014P14960WOAU 4 in the hall construction in order to handle loads inside the hall.

According to one configuration of the present invention the hall construction has a height of at least 12 m.

The length of the hall construction preferably amounts to at least 17 m.

The width of the hall construction is advantageously at least 11 m.

Further features and advantages of the present invention will be apparent from the following description of a hall construction according to one embodiment of the present invention with reference to the accompanying drawings. In the drawings :

PCT/EP2 015/066639 2014P14960WOAU 4a

The mobile hall construction 1 comprises as the main components six structurally identical base frames 2 which are arranged on an industrial foundation 3, six likewise

PCT/EP2 015/066639 2014P14960WOAU 5 structurally identical support pillars 4 of which each is articulatedly mounted on one of the base frames 2 and can be pivoted by means of a drive 5 relative to the base frame 2, and one roof structure 6 which is mounted on the support pillars 4.

Each base frame 2 comprises a substantially rectangular formed ground framework 7. The one free end of the ground framework 7 is provided with an upwardly protruding bearing unit 8 on which the associated support pillar 4 is held for pivotal movement between a horizontal transport position and a vertically straightened-up position. At the other free end of the ground framework 7 there are two support posts 9 on which the support pillar 4 is supported in its horizontal transport position. The drive 5 comprises two hydraulic cylinders which are connected for articulated movement both to the ground framework 7 of the base frame 2 and also to the support pillar 4. The support pillar 4 can correspondingly be pivoted between its transport position and the straightened-up position by moving the hydraulic cylinder in and out accordingly. The dimensions of each base frame 2 are selected so that this can be transported in a container 10 with standardized dimensions.

The roof structure 6 comprises vertical supports 11 which are connectable at their lower free end for articulated movement with the support pillars 4. The vertical supports 11 are connected to one another by two horizontal supports 12 wherein the horizontal supports 12 serve at the same time as guide rails for the crane bridges 13 of two cranes 14 along which a trolley 15 can be moved in a known manner. A roof brace construction 17 of the roof structure 6 is fixed on jib arms 16 extending outwards from the vertical supports 11 and is covered by a tarpaulin 18. The side walls of the hall construction 1 are provided with a corresponding tarpaulin 19.

The assembly of the hall construction 1 illustrated in Figure 1 will now be explained with reference to Figures 2 to 11.

In a first step the industrial foundation 3 for the hall construction 1 is made as is shown in Figure 2. The industrial foundation 3 consists here of a plurality of base plates 20 which are fixed against one another. Alternatively the industrial foundation 3 can also however be erected in a conventional manner by using concrete. A turning block 21 with an integrated pivotal mechanism and a bearing block 22 which are required for straightening up a turbine rotor for the purpose of carrying out maintenance and/or repair work are furthermore mounted on the industrial foundation 3.

In a further step the base frames 2 with the support pillars 4 located thereon are removed from the containers 10 and arranged on the industrial foundation 3, as shown in Figure 3. The base frames 2 can then be fixed on the industrial foundation 3 and/or against one another in order to increase the rigidity of the arrangement. Alternatively the hall construction 1 can however also be designed so that the base frames 2 remain in the containers 10 wherein the containers 10 after removing the container lids are erected relative to one another and fastened to one another and/or to the foundation 3. In this case, the finished hall construction 1 is then encased in the lower region at the sides by the containers 4, as shown in Figure 15. Elsewhere the construction illustrated in Figure 15 corresponds to the construction illustrated in Figure 1, for which the same or similar components are provided with the same reference numerals .

The vertical supports 11 with the jib arms 16 arranged thereon are then fixed for articulated movement to the free ends of the support pillars 4, as shown in Figure 4.

PCT/EP2 015/066639 2014P14960WOAU 7

The vertical supports 11 are then connected to one another by using the horizontal supports 12 according to Figure 5.

In a further step the crane bridges 13 of the cranes 14 are mounted with the trolleys 15 arranged thereon between the horizontal supports 12, whereby the rigidity of the roof construction is increased. Should it then be necessary to further increase the rigidity additionally in the region of the free ends of the horizontal supports 12 transverse supports are provided to connect these together, even if this is not shown here in the present case.

According to Figure 7 the roof brace construction 17 of the roof structure 6 is then fastened on the jib arms 16 of the vertical supports 11.

The tarpaulin 18 can then be fixed on the roof brace construction 17 according to Figure 8.

With reference to Figures 9 and 10 the support pillars 4 are now moved from their horizontal transport position into their vertically straightened-up positon by using the drives 5. Owing to the fact that the vertical supports 11 of the roof structure 6 are fixed articulatedly on the support pillars 4, the roof structure 6 remains in the horizontal position during the straightening-up process.

In order to reinforce the hall construction 1 the support pillars 4 are connected together by using reinforcement bars 23 in a further step according to Figure 11.

In a last step as shown in Figure 1 the tarpaulin 19 is fitted.

The hall construction 1 can also be dismantled again in the reverse sequence. PCT/EP2015/066639

2014P14960WOAU

An important advantage which accompanies the previously described mobile hall construction 1, lies in the fact that thanks to the support pillars 4 which can be straightened up automatically by means of the drives 5 the construction can be mounted and dismantled without the use of a high crane.

It should be pointed out that more particularly the number of base frames 2, support pillars 4 and drives 5 is variable in dependence on the desired dimensions of the hall construction 1. Furthermore it is possible to design the support pillars 4 and/or the vertical supports 12 telescopic in dependence on the desired height of the hall construction 1 in order to ensure that the individual components and modules of the hall construction 1 can be transported in containers 10 of standardized dimensions.

Figures 12 to 14 show by way of example the straightening-up of a turbine rotor 24 by using the turning block 21, the bearing block 22 and a crane 14. In a first step the turbine rotor 24 which is to be processed is set down on the turning block 21 and the bearing block 22 by using the crane 14, and is then fixed on the pivotal mechanism provided on the turning block 21. The turbine rotor 24 can now by using the pivotal mechanism as well as by using the crane 14 be moved into the vertical position and locked in this position in order to carry out the ensuing maintenance and/or repair work on the upright turbine rotor 24. More particularly the turbine rotor 24 can be unstacked without problem in this position.

Although the invention was illustrated and described in further detail using the preferred exemplary embodiment, the invention is not restricted by the disclosed examples, and other variations can be derived therefrom by the person skilled in the art without departing from the scope of protection of the invention.
