Abstract
The present invention pertains to a device for installing and removing gas purging plugs (17) for metallurgical vessels, comprising a guide (7) for axially displacing the gas purging plug (17). On the one hand, movement exactly in the axial direction can be achieved during introduction, and, on the other hand, the extracted gas purging plug can be brought into an ejection position by providing hinges (6, 11), which permit at least two independent pivoting movements of the gas purging plug (17) around different axes (6a, 11a).
Claims14
Device for installing and removing gas purging plugs (17) for metallurgical vessels, comprising a guide (7) for axially displacing the gas purging plug (17), a first hinge (6) having an axis (6a) for pivoting the gas purging plug into a maintenance position, and a second hinge (11), whose axis (11a) extends essentially at right angles to the axis (6a) of the first hinge (6).
Device for installing and removing gas purging plugs (17) for metallurgical vessels, comprising a guide (7) for axially displacing the gas purging plug (17), a first hinge (6) having an axis (6a) extending vertically for pivoting the gas purging plug into a maintenance position, and a second hinge (11), whose axis (11a) extends horizontally essentially at right angles to the axis (6a) of the first hinge (6),
- the first hinge (6) being detachably coupled to the metallurgical vessel, the guide (7) being pivotally connected to the first hinge (6),
- wherein the guide (7) contains a bar, on which a slide (9) is slidably arranged,
- wherein the first hinge (6) permits the guide (7) to be pivoted in relation to the vessel, and the second hinge (11) permits the gas purging plug (17) to be pivoted in relation to the slide (9),
- wherein the second hinge (11) is rigidly connected to the slide (9) and rotatably holds on the slide (9) a head (12), which can be fixed by means of a locking means (10),
- wherein a guide tube (14) for manipulating the gas purging plug (17) is guided axially displaceably in the head (12), and a tool (15a, 15b;
- 31) can be attached to the guide tube (14) for connection to the gas purging plug (17),
- wherein support plungers (20a and 20b) for extracting the gas purging plug (17), which are arranged in a regular pattern around the axis (17a) of the gas purging plug (17), are provided,
- wherein two support plungers (20a and 20b), whose axes are located in one plane, which contains the axis (17a) of the gas purging plug (17), are provided at the head (12),
- wherein hydraulic plungers (21a and 21b) are provided for extracting the gas purging plug (17),
- further including mounting means for mounting a compressed-air hammer (26) for pressing the gas purging plug (17) into the vessel,
- further including a coupling piece (5) for detachably fastening the device to the vessel,
- wherein a fine adjustment means (13) are arranged in the area of the slide (9) for accurately aligning the gas purging plug (17).
