Definitions
- the invention relates to a device for clamping refractory plates in metallic frames of slide closures for the pouring of metallurgical vessels, with a wedge piece that exerts wedge action by adjusting by means of a threaded bolt arranged in the frame over a driving surface inclined to the plate circumference.
- the wedge piece on the thread of a rotatably mounted threaded bolt in the frame is movable and acts with its driving surface on the pressure surface of a sliding jaw which slides in the frame and inclined with the wedge piece over the driving surface Guideways engaged.
- the procedure is expediently such that the clamping jaw slides in a bed of the frame and thereby comprises the U-shaped wedge piece which is movable on the threaded bolt and has longitudinal sides lying in the sliding direction, in whose contact area the guideways lie.
- These are advantageously designed as grooves arranged on the pressure surface of the clamping jaw in the longitudinal sides and counter-profiled springs of the wedge piece.
- the invention proposes that the bolt be arranged perpendicular or almost perpendicular to the plane of the plate and supported with a collar in a recessed recess in the frame and a socket profile in the threaded part pointing towards the mounting surface of the frame Has. This results in a compact construction of the device, which is fully integrated under tension in the frame.
- the invention is explained below with reference to the drawing using an exemplary embodiment. Show it:
- FIG. 1 shows a linear slide closure equipped with tensioning devices according to the invention in longitudinal section
- FIG. 2 shows a partial top view of a tensioning device on the slide plate and frame unit of the closure
- FIG. 3 shows a section along the line III-III of FIG. 2 on a larger scale
- FIG. 4 shows a plan view of part 8 removed from FIG. 3,
- FIG. 5 shows a cross section of part 8 according to FIG. 4,
- Figure 6 is a plan view of part 18 of Figure 3.
- Figure 7 is a side view of part 18 of Figure 6.
- the slide closure 1 has two fire-resistant closure plates 2, a stationary base plate and an adjustable slide plate. Both are held in metallic frames 3.
- the base plate in the housing frame 4 and the slide plate in the slide frame 5, which can be pivoted out about the axis 6 from the operating position in a position moved beyond the closed position.
- the identical clamping devices 7 are accessible with which the plates 2 are clamped in their frame 3 in order to avoid relative movements between the plate 2 and the frame 3 when the slide frame 5 is adjusted . Further devices can be provided for clamping the fixed lower plate on three-plate slide closures.
- 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 by means of a sheet metal tire 13 mounted thereon. the ends of which are extended into grooves 17 arranged on the inner sides 16 of the U-legs with the same inclined position (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 adjustable 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. This engages with a collar 24 a shoulder 25 of the bore 22 piercing the frame thickness and carries in its thread-side end face 26 a profile 24 for inserting a socket wrench 28.
- the part 29 of the frame bore 22, which is extended on the shoulder 25, is the insertion side of the bolt 23 and through a Stopper 30 closable.
- the wedge piece 18 borders with its rounded peripheral region 30, which is not encompassed by the clamping jaw 7, against the transverse wall 32 which ends the sliding bed 10 in the frame 3.
- the device 7 on other peripheral regions of the plate 2 as the end region shown. Furthermore, 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.
- the threaded bolt could be mounted parallel to the plane of the plate and its circumference in the frame 3 instead of perpendicular; the drive and pressure surfaces would then have to be oblique in the horizontal direction, and in a corresponding manner to the exemplary embodiment, a driver spring formed on the drive surface would engage with a groove provided in the clamping jaw.
