This measure can be implemented in two ways, namely with stands with stationary roll stands and intermediate device between a stand and the another of a rolling train, which devices the rolling stock Rotate essentially by 90, or with stationary rolling stands, the oh along the rolling train alternate with tiltable roll stands.

For fast systems, the second solution is preferred, because it is never more reliable and has the highest possible rolling speed nd.i opportunities made possible.

The roll stand *? usually, depending on the construction the rolling train, two or three superposed rollers. '

The movable, i.e. tiltable, scaffolding always bind equipped with two superimposed rollers. Tiltable As can be seen from the foregoing, scaffolds are such Scaffolding, bore the axis of the rolls horizontally or can be placed vertically.

The present invention is therefore concerned with Dijowalzgerür.ten, which can be requested both horizontally and vertically. Of this technical problem

- 3 609816/0898

has already been approached from different sides and therefore different solutions are known.

However, in order to be functional, a tiltable duo scaffolding must meet various requirements; above all, its dimensions must be as small as possible to make it easy and with the least Space required in the rolling system can be installed.

A second problem is the transfer of the rotational movement to the rollers in vertical and horizontal direction Direction, which, if it takes place favorably, nine better utilization of the installed power or an increase the installed capacity by increasing the versatility of the scaffolding.

Another problem derives from the possibility of rapid handling of the scaffolding, both in terms of the replacement of the rollers, as well as the setting of the caliber and the pivoting from the horizontal to the vertical and vice versa.

Another requirement is the blocking of the scaffolding in the working position, be it vertical or horizontal.

All of these problems have been raised on various occasions Tried to solve, but without the optimal, even the The solution aimed for in the present invention has been found.

The transmission of the movement was realized 'by a drive member rotating together with the roll stand or a drive source or one that is stationary on the foundation Engine were provided; but this inevitably leads to very little ones due to the weight installed capacity and consequently limits the capacity of the scaffolding to a large extent.

The second problem Ln was picked up the two aforementioned patents, but us was treated exhaustively only in the IT PG 7 ^fi 3 ΎΑ, the solution found was, however, space-consuming, expensive and complicated.

The third problem is only caused by the mentioned i i.n 1 ieni besides Patent specification picked up and in the wake more complicated Solutions that are vague to the aforementioned indistinct ρiatzaufwendigen, expensive and complicated Solution led. For example, it is not clear how to represent. the scaffolding to be replaced is to be removed; further required the 'system of securing the presence of a worker at the roll stand; Ultimately, this is the system used for you · centering the desired caliber expensive, time consuming and subject to rapid wear and tear.

The solution to the fourth problem is by choosing for the third problem is caused, but with the known tiltable duo scaffolding, this solution is time-consuming and machine-consuming, expensive and not very secure.

The present invention has the task of an increased, usable drive power on the roller

Another design according to the invention provides that the axes of the drives are tangential to a circle, whose center is in the center of rotation of the tiltable frame, with a drive directly connected to the reduction gear is connected and the other between the latter between a cardan joint and an angle transmission between-schalfcet is.

According to the invention one can proceed so that the connected to the front face of the scaffold hydraulic Piston devices up to the complete exit of the frame from the Absfcützschlitten and for loading Can be extended on the carrier trolley set up on the front are.

Another design according to the invention provides that which interact with the floor of the scaffolding hydraulic piston devices raise the scaffold, by placing the external inclined surfaces on the sides of the shoulders in those formed in the slide wedged lateral inner sloping surfaces.

Finally, you can build the two-roll stand so that the reduction gear is on the tiltable frame is arranged, which transmits the movement to the rollers via extensions, with the distance between Reduction gear and frame is variable depending on the selected calibration, whereby one possibly according to a further proposal of the invention can proceed so that the tiltable frame with the center on rollers running in stationary guides rotates, the rotation being effected by at least one hydraulic piston.

In the displaceable frame y \ - counter surfaces 35 are provided, on which 42 prefer to attack, with the help of which the entire rolling stand 53 can be raised, with the running wheels 46 being lifted at the same time, whereupon the stand 53 is in the desired position thanks to the lateral inclined surfaces 55 Position can be blocked, since the latter can be blocked against the corresponding laterally provided inclined flaps 56, which come to rest in the displaceable frame 3 ^. The hydraulic cylinder 37 has a front connection 39 with which it is attached to the end face of the scaffolding and serves to guide the scaffolding 53 to the sliding frame 3 to the carriage 54 in order to enable the scaffolding to be replaced in this way to allow, the hydraulic cylinder 37 is pivotably articulated at 30. The shoulders 40 of the rolling stand 53 contain chambers 43 at the bottom, in which a jack 4-1, which is used to preload the lower cylinder 50, and a jack 42 run in opposite directions. The clutches 44 serve to connect and transmit the movement between the shafts IH and ΙΟ and the cylinder heads 49 and 50.

The couplings 44 are mounted in the holder 45, so that even then, ^ if they are not in with the cylinders Connection, they remain in their position. The brackets 4-5 are of a known type.

The roller 69 is carried by the wheels 51 and 57, a front projection 5 & being provided in the front. The axially-frontally movable holder 59 has a approximately spoon-like seat 60, so that there the frontal End part 58 can be received and further backwards with a piston 61 controlling the axial movement Connection is given. The piston 61 is about a

Chamber 63 can be operated hydraulically, with the return of the piston is ensured by the springs 62 provided on the other side of the piston are. For blocking the swivel rahine ns is a device 64 is provided, which consists of the parts to 63.

The mode of operation is explained in more detail below:

In this explanation of the position, how they is shown in FIG. In this position, the piston rod of the jack is moved forward until the front connection 39 is over the frame 53 'has moved out and comes to rest in front of the outer shoulder 40.

The port 39 is then automatically connected to the outer shoulder 40 attached when the rails of the carriage 54 with the on the sliding frame provided running rails 60 are aligned. This escaping is necessary so that the wheels 46 can run into the running rails.

If the cylinder '37 is now actuated, you can move the frame 53 from position 53 ″ to 53.

After reaching the position 53, the scaffolding is determined, and Zwsr in that one ^; the chambers 43 are acted upon by an oil pressure control. By this oil pressure control, the pistons 41 and 4? pushed outwards.

It can be seen that two processes take place at the same time, the first being the preload which is the Generate piston 41 in the lower set of roller 50

609816/0696

and the second is the blocking; the scaffolding in relation on the verachi nnnnnnnn 34 dnr.

The blocking takes place in that the pistons 42 push against the opposing surfaces 35 present in the displaceable frame 34 and the wheels 46 lift off the running rails 66, with the inclined surfaces 55 on the sides of the two shoulders 40 also opposing the inner lateral inclined surfaces 56 The sliding frame 3 ^ come to rest so that a stable blocking is achieved. In order to arrange the frame 53 so that the axis of rotation 28 coincides with the axis of the desired calibration, it is sufficient to actuate the cylinder 36, which shifts the displaceable bracket 34 against the swivel frame 7 . This centering is necessary so that the desired calibration remains constantly centered both with a horizontal stand (FIG. 1) and with a vertical stand (FIG. 3).

After the framework 53 has been brought into the correct position with respect to the rotation axis 23 and the guide channel 67 comes to lie in the framework in such a way that it coincides with the selected calibration, it is possible to fix the framework 53 in the desired position. Assuming that it is to be placed vertically (Figure 3), the chamber 63 of the locking devices 64 and 64 'is pressurized until the force of the springs 62 and the spoons 60 are pushed slightly forward , release the front end parts of the pin 57. After these parts have been released from the lock by the spoon 60, the hydraulic cylinders 31 are actuated.

Simultaneously with the whole swivel frame 27. and

609816/0696

imposed on all toilets supported by it Rotation, the pressure is removed from the chambers 63, so the holder 9 retracts completely and before the end parts of the braids 57 is possible that Position of the spoons 60 of the devices 64 'and 64' ' to overtake. After the rotation has been carried out, the chambers 63 are wetted under pressure, whereupon the swivel frame 27 is lowered until the front end parts of the pin 57 come to rest in <3 "n spoons 60.

If you now relieve the pressure in chambers 63, block the springs 6? the spoons 60 against you. Handler 58 and the weight blocked the pegs against the spoons 60 (Figure 6). Before the start of the rotation, by actuating the cylinder 31 »it is however, required the hydraulic cylinder 14 to actuate, which releases the motor IO from the coupling half (Figure 5). When the swing frame 27 in the vertical position ir.t, you can by actuating the hydraulic cylinder 14 again the connection between the coupling half of the motor and the coupling half 16 'of the frame (Figure 3)

But not only according to the proposal of the

finding the desired result with the preferred embodiment described above, but it is also mixed, shapes and dimensions to change and the scaffolding by another with wedge-shaped devices and blocking devices to replace. It is also possible to provide a hydraulic drive mechanism and the clutches by other, replace organs serving the same purpose. Of course you can't just have a pneumatic one or provide hydraulic control, but also use a servo control in general.
