Tiltable Metallurgical Vessel

Abstract

A tiltable metallurgical vessel having a carrying ring at least partially around it. A metallurgical supporting bracket fastened on the metallurgical vessel rests on the ring. The vessel is releasably fixed on the support ring by a clamping device actuated by a pressure-medium cylinder. The clamping means interacts with a locking bracket fastened on the vessel. The clamping device moves between a release position, releasing it from the locking bracket and clamping position, clamping the locking bracket together with the support ring, The clamping device comprises a housing, a clamping anchor, a pivot lever and a pressure-medium cylinder, which acts on the pivot lever. The clamping anchor is guided in a pivotable manner in a guide means in the housing. The anchor is pivotably articulated on a pivotable lever, and the pivot lever is supported in a pivotable manner in the housing.

1 . A tiltable metallurgical vessel comprising
 a metallurgical vessel, a support ring which at least partially surrounds the metallurgical vessel, the metallurgical vessel resting on the support ring;   a clamping device releasably fixing the metallurgical vessel on the support ring;   a locking bracket fastened to the metallurgical vessel, the clamping device cooperating with the bracket, the clamping device being operable between a release position releasing the locking bracket from the support ring and a clamping position clamping the locking bracket together with the support ring,   the clamping device:   comprising a guiding plate including a guide thereon for controlling operable movement of a clamping anchor;   a clamping anchor operably movable to selectively clamp to the locking bracket and to release clamping to the locking bracket; the clamping anchor being connected with the guide for thereby guiding movement of the anchor;   a pivoting lever pivotable with respect to the plate and connected with the anchor such that pivoting of the lever moves the anchor to clamp to and release the bracket;   a device for operating the pivoting lever such that the clamping anchor is guided in a pivotable movable manner in the guide in the plate, the anchor is pivotably articulated on the pivoting lever and the pivoting lever is also pivotably supported by the plate such that guided motion of the anchor selectively clamps and unclamps the anchor to the bracket.   
     
     
         2 . The tiltable metallurgical vessel as claimed in  claim 1 , wherein
 the clamping anchor includes a clamping anchor shank and a clamping head on the shank the head including a first supporting surface;   the locking bracket having an insertion slot for receiving the clamping anchor shank and having a second mating supporting surface for supporting the clamping head, wherein in the clamping position, the first supporting surface of the clamping head is pressed against the second mating support surface of the locking bracket and, in the release position, the clamping head has been pivoted to a position outside the insertion slot which allows a movement lifting the metallurgical vessel off the support ring.   
     
     
         3 . The tiltable metallurgical vessel as claimed in  claim 1  wherein the clamping device forms or comprises a toggle lever mechanism which is operable to trigger self-locking at a self-locking point in the clamping position, and a stop for limiting the displacement path of the mechanism. 
     
     
         4 . The tiltable metallurgical vessel as claimed in  claim 3 , wherein the stop is formed by the slotted guide. 
     
     
         5 . The tiltable metallurgical vessel as claimed in  claim 2 , further comprising an expansion element operable on the clamping device. 
     
     
         6 . The tiltable metallurgical vessel as claimed in  claim 5 , wherein the expansion element is integrated in the clamping anchor. 
     
     
         7 . The tiltable metallurgical vessel as claimed in  claim 6 , wherein the expansion element is formed by a cup spring assembly. 
     
     
         8 . The tiltable metallurgical vessel as claimed in  claim 2 , wherein the guide is arranged in the plate of the clamping device such that, during the movement of the clamping head from the clamping position into the release position, in a first movement phase, the clamping head of the clamping anchor is moved such that the first supporting surface is lifted off the second mating supporting surface on the locking bracket, and during a further movement phase of the clamping head, the clamping head of the clamping anchor (is moved with a pivoting movement out of the insertion slot of the locking bracket. 
     
     
         9 . The tiltable metallurgical vessel as claimed in  claim 8 , wherein the guide in the plate of the clamping device comprises an arcuate guiding groove and a guiding bolt of the clamping anchor engages and is guided in the groove in a sliding manner. 
     
     
         10 . The tiltable metallurgical vessel as claimed in  claim 1 , wherein the clamping device is formed as a preassembled module and is releasably fastened to the support ring. 
     
     
         11 . The tiltable metallurgical vessel as claimed in  claim 18 , wherein the pressure medium cylinder is a pneumatic cylinder. 
     
     
         12 . The tiltable metallurgical vessel as claimed in  claim 1 , further comprising an enclosure fastened to the metallurgical vessel and surrounding the locking bracket that is open in the direction of the support ring. 
     
     
         13 . The tiltable metallurgical vessel as claimed in  claim 1 , wherein the support ring is at a distance from the vessel. 
     
     
         14 . The tiltable metallurgical vessel as claimed in  claim 13 , further comprising supporting brackets supporting the vessel on the ring. 
     
     
         15 . The tiltable metallurgical vessel as claimed in  claim 1 , wherein the guide comprises a slot in the plate. 
     
     
         16 . The tiltable metallurgical vessel as claimed in  claim 1 , further comprising a housing for the clamping anchor and the plate comprises a wall of the housing. 
     
     
         17 . The tiltable metallurgical vessel as claimed in  claim 16 , wherein the guide comprises a slot in the plate. 
     
     
         18 . The tiltable metallurgical vessel as claimed in  claim 1 , wherein the device for operating the pivoting lever comprises a pressure medium cylinder operable, or pivoting the lever.
