Definitions

  • the invention relates to a bracing device for a slide closure provided on the spout of a metal-containing container, with a housing, a base plate fixed therein and a slide plate sealingly resting thereon, which is adjustably mounted in a housing cover and against the base plate by means of articulated on the housing, engaging under the housing cover Bracing means can be pressed resiliently.
  • the slide plate is braced against the base plate by means of clamping screw devices which engage on the housing and on the cover over the circumferential sides and generate a contact pressure on the slide plate when screwed together.
  • the clamping screw devices each have a screw bolt, which is pivotally suspended on a pivot axis and acts as a clamping element, a thread-free sleeve under the housing cover, a clamping nut and disc springs inserted between the sleeve and the nut.
  • the object of the present invention is to improve the suspension acting via the tensioning means articulated on the housing.
  • the tensioning means consist of tensioning elements and bending springs
  • the tensioning elements are articulated on the bending springs in such a way that the articulation axes of the tensioning elements coincide with the longitudinal axes of the bending springs.
  • a bending spring such as a simple elongated spring leaf, a bar spring or a leaf spring layered from spring leaves, can be adjusted with great accuracy to the required tensioning force between the closure housing and the housing cover. They are easy to assemble and disassemble and at the same time fulfill two functions: on the one hand the cushioning of the housing cover on the housing and on the other hand the articulation of the clamping elements.
  • the bending springs can be easily checked due to their clear arrangement.
  • the bending springs are preferably mounted at both ends in the closure housing and carry at least one a) s eye screw designed with a tensioning nut and secured against lateral displacement.
  • Layered leaf springs have proven to be particularly advantageous for use as bending springs, which are expediently secured at one end by a cross bolt and held in a bushing, while the other end has free support in the longitudinal direction in order not to be exposed to additional tensile stresses.
  • the bushing can be fixed on the housing by means of an adjusting bolt in two opposite bending directions of a bending spring, which can be rotated in this way if necessary from a used bending side to the still unused one.
  • Each bending spring is secured against excessive deflection by a stop which is provided on the lock housing. Such stops also prevent the eyebolts carried by the bending springs from shifting sideways.
  • a conventional slide closure 20 which is not described in detail below, is attached to a partially illustrated metal melting container 10.
  • the container 10 essentially consists of a steel casing 18, a refractory lining 12 and a pouring sleeve 14 with a pouring opening 16 which extends through the slide closure in the open position.
  • the slide closure 20 fastened to the steel jacket 18 of the container 10 consists essentially of a housing 22 screwed to the steel jacket 18, an upper refractory base plate 24 inserted therein, which adjoins the pouring sleeve 14, a refractory slide plate 26 arranged sealingly thereto, a longitudinally displaceable slide frame 28, in which a pouring sleeve 23 and the slide plate 26 are held, furthermore from a final housing cover 30 with guides 32 for the frame 28 and from tensioning means 40 for fastening the housing cover 30 to the housing. Both housing 22 and cover 30 are connected via a hinge joint 34.
  • the clamping means 40 each consist of a bending spring 46, which is clamped on both sides and is designed as a leaf spring, and a clamping element 42, 44 in the form of an eyebolt 42 provided with a clamping nut 44, which is suspended approximately in the middle of the bending spring 46.
  • the spring 46 is rounded at its longitudinal edges in order to allow the eyebolts 42 to pivot out, which are from flat walls at recesses 50 of the housing 22 are secured against lateral displacement.
  • Further recesses 36 and 38 arranged in the housing cover 30 enable the eyebolts to be swiveled in under the housing cover 30, for the housing 22 and the housing cover 30 to be braced in accordance with the operation.
  • two bending springs 46 are provided on each of the two longitudinal sides of the closure 20, each of which extends over half the side length and is supported in the housing 22 at its two ends 46 ′ and 46 ′′.
  • the storage takes place, as is particularly evident from FIG. 3 can be seen, at the outer end 46 'by means of a bushing 49 with cross bolts 48, while the inner end 46 "in the profile holes 54 is freely movable in the longitudinal direction.
  • the bush 49 is held by an adjusting bolt 47 screwed into the housing 22 and can be rotated through 180 ° if the bending spring 46 has suffered permanent deformation in the direction of action.
  • the deflection of the bending spring 46 is limited by housing stops 52 which are provided in the passageway 52 flanking the recess 50 for the bending spring 46.
  • bending spring 46 on the longitudinal side of the closure, which spring also extends over its entire length and also has two tensioning elements or eyebolts 42, 44.
  • three and more tensioning elements 42, 44 could also be used for a closure side, possibly with staggered bending springs 46 arranged one above the other.
  • the bending springs 46 could also be designed as spring bars.
  • the spring elements could similarly be fixed laterally in the housing cover, while the tensioning elements would equally be pivotably suspended on these spring elements. Corresponding recesses in the housing would allow the cover to be braced on the housing.

Abstract

Dispositif de mise en tension pour fermetures coulissantes du bec de coulée de récipients métallurgiques. Afin de conférer un effet de ressort pour la mise en tension du boîtier de fermeture (22) et du couvercle du boîtier (30) par des éléments tendeurs (42, 44) qui relient ces deux parties et qui sont articulés au boîtier (22) et saisissent la partie inférieure du couvercle (30), le dispositif comporte des ressorts de flexion (26) qui servent d'axes d'articulation aux éléments tendeurs. La double fonction des ressorts de flexion (26) permet ainsi d'obtenir aisément la mise en tension (26).

Claims (6)

1. Dispositif de mise en tension pour un obturateur à tiroir (20) qui est prévu à l'ouverture de coulée d'un récipient (10) contenant un métal en fusion et comprend un boîtier (22), une plaque de fond (24) disposée dans ce dernier de manière fixe et une plaque-tiroir (26) qui est appliquée contre cette dernière avec effet d'étanchéité, est montée dans un couvercle de boîtier (30) de manière à pouvoir être déplacée et peut être pressée élastiquement contre la plaque de fond (24) à l'aide de moyens de mise en tension (40) articulés sur le boîtier (22) et agissant par le bas sur le couvercle de boîtier (30), caractérisé en ce que les moyens de mise en tension sont composés d'éléments de serrage (42,44) et de ressorts de flexion (46) et en ce que les éléments de serrage (42, 44) sont articulés sur les ressorts de flexion (46) de telle sorte que les axes d'articulation des éléments de serrage (42, 44) coïncident avec les axes longitudinaux des ressorts de flexion (46).
