Definitions

  • the invention relates to a device for clamping refractory plates in metallic frames of sliding closures for the pouring of metallurgical vessels, with a wedge piece, which is movable on the thread of a threaded bolt rotatably mounted in the frame, by adjusting by means of the threaded bolt wedge action over an oblique to plate circumferential inclined driving surface and with this acts on the pressure surface of a sliding jaw in the frame.
  • the stated object is essentially achieved in that the clamping jaw is in engagement with the wedge piece via guide tracks inclined in accordance with the driving surface.
  • the clamping jaw is in engagement with the wedge piece via guide tracks inclined in accordance with the driving surface.
  • Each device 7 has a U-shaped clamping jaw 8 which is guided in a sliding bed 10 of the frame 3 with flank strips 9 provided on the U-legs.
  • the outer side of the U-web connecting the legs serves as a contact side 11 with respect to the plate circumference 14, specifically via a sheet metal tire 13 mounted thereon. whose ends in on the inner sides 16 of the U-legs with grooves 17 arranged in the same inclined position are extended into them (FIGS. 4 and 5).
  • the U-shaped clamping jaw 8 comprises a wedge piece 18, which engages in the grooves 17 with springs 19 and whose driving surface 20 forms the counter surface to the pressure surface 15. Conversely, at least one spring could also be formed in the clamping jaw 8, which would be in a corresponding manner in engagement with a groove formed in the wedge piece 18.
  • the wedge piece 18, which is provided with a threaded bore 21, is arranged vertically to the plane of the plate 2 and frame 3 and is arranged on a threaded bolt 23 which is rotatable about the longitudinal axis in a stepped bore 22 of the frame 3.
  • a plurality of devices 7 can be provided distributed over the plate circumference 14, which in cooperation with the contact surface 11 of the clamping jaw 8 can also have an oval or round shape, for example.

Abstract

Un dispositif de serrage de plaques ignifuges (2) dans le cadre métallique (3) d'enclenchements à arbres comprend une mâchoire de serrage (8) qui peut être pressée contre la périphérie (14) de la plaque et qui est actionnée par une pièce en coin (18) ajustable à cet effet sur le filetage d'un boulon fileté (23) agencé rotatif dans le cadre (3). La pièce en coin (18) s'engage dans la mâchoire de serrage (8) par des rainures de guidage (17, 19). On doit ainsi obtenir un meilleur fonctionnement du dispositif de serrage, en particulier lors du desserrage.

Claims (4)

1. Dispositif de serrage de plaques réfractaires dans des cadres métalliques d'obturateurs à coulisse d'orifices de coulée de récipients métallurgiques, comportant une pièce de clavetage qui est mobile sur le filetage d'une vis montée rotative dans le cadre, qui excerce, par déplacement au moyen de la vis, un effet de coin par une surface d'entraînement inclinée de façon oblique par rapport à la périphérie de la plaque, et agit par ladite surface d'entraînement sur la surface de pression d'une mâchoire de serrage coulissant dans le cadre, caractérisé en ce que la mâchoire de serrage (8) est en prise avec la pièce de clavetage (18) au moyen de chemins de guidage (17, 19) inclinés de façon correspondante à la surface d'entraînement (20).
2. Dispositif selon la revendication 1, caractérisé en ce que la mâchoire de serrage (8) coulisse dans une glissière (10) du cadre (3) et entoure la pièce de clavetage (18) à la manière d' un U avec des côtés longitudinaux (16) qui sont disposés dans la direction de glissement et dans la zone de contact desquels sont disposés les chemins de guidage (17, 19).
3. Dispositif selon la revendication 2, caractérisé en ce que les chemins de guidage (17, 19) sont réalisés sous la forme de rainures (17) disposées contre la surface de pression (15) de la mâchoire de serrage (8) dans les côtés longitudinaux (16), et de nervures (19) profilées en sens inverse.
4. Dispositif selon l'une quelconque des revendications précédentes, caractérisé en ce que la vis (23) est disposée perpendiculairement ou presque perpendiculairement au plan de la plaque et est logée avec un collet (24) dans un évidement à gradin (22, 29) et présente un profil pour clé mâle (27) dans la partie filetée tournée vers la surface de montage du cadre (3).
