Casting ladle tilting racks are made with a device to secure the ladle against falling out provided on the frame. The state of the art are tilting racks with the socket pegs Bearings, on the adjustable bearing cover of which a linearly guided control tappet engages. It is an electrically, hydraulically or pneumatically adjusting device is provided as the ram drive.

The object of the invention is to create a reliable one while saving such an adjustment device To ensure that the pan is unlocked when tilting back (into its starting position).

This object is achieved according to the invention in that the plunger is in a fixed drive cam interlocks positively with the inner and outer tracks, their mirror-inverted curved branches - for each one of the two tilting directions - start from the tappet center position. Such a drive curve automatically and reliably ensures that the pan is unlocked again. Therefore it cannot do this come that the tilting frame when lifting out the erected pan due to lack of unlocking damaged. This is the case with known devices with only frictional control the safety device possible.

The drawing illustrates some exemplary embodiments of the subject matter of the invention, namely shows

Fig. 1 is a view of the tilting frame with attached Pan;

F i g. 2 the ram drive on an enlarged scale, specifically in the pan starting position;

F i g. 3 in a tilted position;

F i g. 4 and 5 analogously to FIG. 2 each a modified version of the bearing cap.

The pins 1 of the pouring ladle 2 are each supported in a hanger 3. With this, the pan is placed on a tilting frame 4, the legs 4 'of which have a recess 5 (FIG. 2) at the upper end for inserting the hanger 3. Pins 6 attached to the legs 4 'are each supported in a stationary stand 7. A tilt motor 10 engages one of the two pivot pins 6 by means of a reduction gear 8, 9,

On the inside of the legs 4 'arranged drivers 11 overlap stops 12 provided on the pan shell and thus transmit the tilting moment from the tilting frame 4 to the pan 2, specifically in both tilting directions.

As shown in FIG. 2, two cover parts 13, 14 are provided for reaching over the hanger hub 3 'and each as part of a two-armed swivel device for securing a tilting vessel,
especially a ladle,
in a tilting frame

hebeis 15 formed, which is fixed to a frame

ao axis 16 is mounted. A link 17 is connected to the lower arm of each lever 15 and is in turn connected to a control tappet 18. The ram 18 guided in the frame leg 4 'carries a control roller 18' which is fitted into a lifting curve with an inner track 19 'and an outer track 19 ".

When the frame 4 is tilted about its bearing pin 6, the roller 18 'moves from its central position (FIG. 2) in the lifting curve to one side or the other and has the two bearing cover parts 13 and at the end of the respective lifting curve leg (FIG. 3) 14 inevitably moved into its closed position. When tilting further, the roller 18 'moves along an arcuate path 20 , which immediately adjoins the outer path 19 "of the lifting curve and threading the roller 18' perfectly back into the lifting curve when tilting back or when tilting further through 360 °.

When the two links 17, as is known per se, in the lid closed position (FIG. 3) have passed their dead center position, in which they are both precisely aligned with one another, they act as a locking mechanism by preventing the lid parts 13 from opening unintentionally. 14 secure. Only after re-threading the roller 18 'in ^{FIG. 1,} the lifting curve, are the control arms pivoted back by the tappet 18 beyond their dead center position, thereby releasing an unlocking.

According to FIG. 4, the cover parts 13 and 14 do not need to overlap the hanger hub 3 '. The hub 3 'is provided with lateral recesses 21 in this embodiment. The cover parts 13 ', 14' adapted to the recess engage in this in their closed position.

Finally, FIG. 5 another possible embodiment in which the free ends the two-armed pivot lever 15 'does not attack the hanger hub 3', but rather on the socket pin 1 and are adapted to this. Such a design comes into consideration when the pan with their pin 1 directly, so not with HiEe a hanger, placed on the tilting frame will.

In addition, a one-piece cover is also possible within the scope of the invention, e.g. in the manner that only one of the two levers 15 is provided, the free end of which forms the one-piece cover.

The advantages offered by the invention are not only for ladles, but also for tilting vessels of all kinds basically the same, in which the same conditions as in a ladle given are.

Claims (1)

Claim: Device for securing a tilting vessel that is removably inserted in a tilting frame, in particular a pouring ladle, against falling out of the frame with receiving the vessel pegs Bearings, on whose adjustable bearing covers a straight line guided in the tilting frame Control tappet engages, characterized in that the tappet (18) is in a fixed position Drive cam with inner (19 ') and outer (19 ") engages positively, the mirror image of which same curve branches - for each of the two tilting directions - from the ram center position go out.
