Titel:Title:

Pneumatischer Lasthänger.Pneumatic load hanger.

Stand derState of

Technik: Bei der Handhabung von Lasten mit Hebezeugen Technology: When handling loads with lifting equipment

ist ein stoßarmes Heben und Senken, insbesondere bei Komponenten in Kernkraftwerken erforderlich. Dieses trifft im wesentlichen dort zu, wo zusätzlich ein feinfühliges und genaues Positionieren, oder Zusammenfügen gefordert wird.Low-impact lifting and lowering is required, especially for components in nuclear power plants. This applies mainly where sensitive and precise positioning or assembly is also required.

Fundstellen:Locations:

Bei Revisionsarbeiten am Reaktordruckbehälter und seinen Kerneinbauten in Kernkraftwerken.During inspection work on the reactor pressure vessel and its core internals in nuclear power plants.

Problem:Problem:

Lösung:Solution:

Die Kerneinbauten werden zum Teil mit Stangenwerkzeugen, die u.a. am Reaktorgebäudekran hängend transportiert, positioniert und miteinander gekuppelt werden.The core components are partly transported, positioned and coupled together using bar tools, which are suspended from the reactor building crane, among other things.

Die Mechanik der Kuppelstellen wird durch alle Eigenlasten stoßartig belastet.The mechanics of the coupling points are subjected to shock loads from all dead loads.

Der pneumatische Lasthänger ist geeignet zum anhängen an ein Tragmittel mittels Lastanschlagpunkt (Pos.l). Die Last z.B. ein Stangenwerkzeug, wird mit der Aufnahme (Pos.6) verbunden. Das Druckluftsystem, bestehend aus einem Zylinder (Pos.3) und Druckluftspeicher (Pos.4) sind mit Druckluft beaufschlagt und der spezifische Luftdruck im Zylinder ist über die Armaturen (Pos.5) eingestellt. Zur Absicherung der Last, verbindet eine Lastsicherung (Pos.7) die Last mit der Tragkonstruktion (Pos.2). Durch anheben der Last mit dem Lasthänger, macht der Kolben des Zylinders ein Hub und komprimiert die Druckluft. Die komprimierte Druckluft wirkt als Feder, die beim absetzen der Last sich entsprechend dem Hub, entspannt.The pneumatic load hanger is suitable for hanging on a load-bearing device using a load attachment point (item 1). The load, e.g. a bar tool, is connected to the holder (item 6). The compressed air system, consisting of a cylinder (item 3) and compressed air reservoir (item 4) are pressurized with compressed air and the specific air pressure in the cylinder is set using the fittings (item 5). To secure the load, a load securing device (item 7) connects the load to the supporting structure (item 2). By lifting the load with the load hanger, the piston of the cylinder makes a stroke and compresses the compressed air. The compressed compressed air acts as a spring, which relaxes according to the stroke when the load is set down.

(Fig.2 Pos.2) Kolbenstellung 2, Hublast G2 1100N, Hub 115 mm, Kolbendruck 1,5 bar.Schematic representation (Fig.2 Pos.l) piston position 1, pressure on piston 1 bar, G 1 without load. (Fig.2 Pos.2) piston position 2, lifting load G2 1100N, stroke 115 mm, piston pressure 1.5 bar.

(Fig.2 Pos.3) Kolbenstellung 3, Hublast G3 1700N, Hub 85 mm, Kolbendruck 2,3 bar. Die erreichten Vorteile mit dem pneumatischen Lasthänger, sind ein sanftes Kuppeln der Kernbauteile, und somit entstehen keine Beschädigungen,(Fig.2 Pos.3) Piston position 3, lifting load G3 1700N, stroke 85 mm, piston pressure 2.3 bar. The advantages achieved with the pneumatic load hanger are a gentle coupling of the core components, and thus no damage occurs,
