Description

Uppfinnare: H I W Tiefentahl Prioritet begard frdn den 25 ma) 1963 (Farbundsrepubliken Tuskland) Foremal for huvudpatentet ar en skyddsanordning till forhindrande av olycksfall vid arbeten i behallare, t. ex. konvertrar, som aro forsedda med en murad eller stampad infodring, vilken anordning bestar av en uppblasbar, flexibel halkropp, som i uppblast tillstand lagger sig mot behallarens vagg och hindrar delar av infodringen att falla ned. Inventor: H I W Tiefentahl Priority requested from 25 May 1963 (Federal Republic of Tuscany) Form for the main patent is a protective device for the prevention of accidents when working in containers, e.g. converters, which are provided with a masonry or stamped lining, which device consists of an inflatable, flexible sliding body, which in an inflated condition lies against the cradle of the container and prevents parts of the lining from falling down.

Det liar visat sig, att den uppblasbara halkroppen inte sjalv eller endast till en del beh8ver lamna skyddet mot nedfallande delar av infodringen. Det ar tillrackligt att den uppblasbara kroppen, som t. ex. kan ha formen av en ring med cirkulart tvarsnitt, forstyvar anordningen, medan en flexibel men joke uppblasbar mantel helt eller delvis overtager skyddet mot nedfallande delar. It has been found that the inflatable sliding body does not itself or only in part need to leave the protection against falling parts of the lining. It is sufficient that the inflatable body, e.g. may be in the form of a ring with a circular cross-section, stiffens the device, while a flexible but joke inflatable jacket completely or partially takes over the protection against falling parts.

Pa ritningen visas ett utforingsexempel pi uppfinningen i sektion genom en konverter med anordningen enligt uppfinningen visad med uppblast halkropp. The drawing shows an embodiment of the invention in section through a converter with the device according to the invention shown with an inflated hollow body.

Den av en platmantel 1 med eldfast infodring 2 bestaende konvertern har vid sin ovre del en Overhangande vagg 3, fran vilken delar kunna falla ned och skada i konvertern arbetande personal. Den anordning, som enligt uppfinningen shall hindra detta, bestar i huvudsak av en ringformig, uppblasbar halkropp 4, som ar fast vid en av kedjor 5', nat 5", duk 5'", liner eller liknande bestaende mantel 5 och som vid uppblasning lagger sig mot ionvertervaggen och staller ut manteln 5. For halkroppens upphlasning anvands en slang 6. Manteln 5 Or upphangd i en stel ring 7, som i sin tur Or hoj- och sankbart upphangd i en lina 8. Vid halkroppen 4 Oro kedjor 9 eller andra nedtyngande delar anbragta, vilka Ora anordningens hopfallande vid luftens utslappande ur halkroppen 4 snabbare. Efter utslappande av luften intaga kedjorna 9 laget 9'. Anordningen kan hissas upp genom konvertermynningen 10. The converter consisting of a plate jacket 1 with refractory lining 2 has at its upper part an overhanging cradle 3, from which parts can fall down and injure personnel working in the converter. The device which according to the invention is to prevent this consists essentially of an annular, inflatable hollow body 4, which is fixed to one of chains 5 ', nat 5 ", cloth 5'", liner or similar existing jacket 5 and which when inflated lies against the ion converter cradle and displays the jacket 5. A hose is used for unloading the hollow body. 6. The jacket 5 is suspended in a rigid ring 7, which in turn is raised and lowered in a rope. other weighting parts are provided, which Ora the device collapses when the air escapes from the hollow body 4 faster. After loosening the air, the chains 9 occupy the layer 9 '. The device can be hoisted up through the converter orifice 10.

Den uppblasbara halkroppen kan sasom angivet i huvudpatentet besta av eft duhbelvaggigt textilmaterial, av plast eller annat lampligt stoff. The inflatable slip body can, as stated in the main patent, consist of double-walled textile material, plastic or other suitable fabric.

Claims
