Abstract

A device for measuring the movement of plant components which are subjected to mechanical stresses and/or temperature changes, is as follows. A guide element (4) containing two mutually perpendicular bores is attached to the plant component; inside the bores tubes (5,6) each having a writing nib (11) at the end are mounted so that they can slide axially against spring force; the nibs (11) are applied by the forces of the springs onto two mutually perpendicular writing panels (12,13) mounted in a fixed position, so that a written graph of the movements in two perpendicular planes is obtd. Pref. each tube (5,6) contains a wooden pencil with a steel needle as the writing nib. Slits in each of the panels (12,13) and a bore (19) at the corner between them enable marks to be made on the writing sheets (14,15). Used in obtaining long-term recordings of movements of plant in nuclear power stations, partic. ducts etc. It may be used for static and for dynamic movements. The apparatus operates over long periods with minimum maintenance.

Description

Meßeinrichtung für die Bewegung von AnlageteilenMeasuring device for the movement of system parts

Die Erfindung betrifft eine Meßeinrichtung für die Bewegung von Anlageteilen, die mechanischen Beanspruchungen und/oder Temperaturänderungen unterliegen.The invention relates to a measuring device for the movement of system parts, which are subject to mechanical stresses and / or temperature changes.

In großtechnischen Anlagen und insbesondere in Kernkraftwerken ist es vorteilhaft, eine Meßeinrichtung zu besitzen, die weitgehend wartungsfrei und genau die Verschiebung von Rohrleitungen oder anderen Anlageteilen bei statischen und dynamischen Vorgängen erfaßt.In large-scale plants and especially in nuclear power plants It is advantageous to have a measuring device that is largely maintenance-free and exactly the displacement of pipes or other system parts in the case of static and dynamic processes are recorded.

Aufgabe der vorliegenden Erfindung ist es, eine derartige Meßeinrichtung so auszubilden, daß auch über längere Zeiten auftretende Bewegungen genau und weitgehend nicht manipulierbar aufgezeichnet werden können.The object of the present invention is to provide such a measuring device to be trained in such a way that movements occurring over long periods of time are accurate and extensive cannot be recorded in a way that cannot be manipulated.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß mit dem Anlagenteil ein Führungselement mit zwei zueinander senkrechten Bohrungen fest verbunden ist, daß in den Bohrungen Hülsen mit Je einer Schreibspitze in axialer Richtung verschiebbar federnd gelagert sind, daß zwei zueinander senkrechte Platten ortsfest so befestigt sind, daß die Schreibspitze Je einer Hülse federnd an je einer Platte anliegt, und daß auf den Platten eine Schreibunterlage in definierter Lage befestigbar ist.According to the invention, this object is achieved in that with the system part a guide element is firmly connected with two holes perpendicular to one another, that in the bores sleeves each with a writing tip displaceable in the axial direction are resiliently mounted that two mutually perpendicular plates are fixed in place are that the writing tip of each sleeve rests resiliently on each plate, and that a writing pad can be fastened in a defined position on the plates.

Ein Ausführungsbeispiel ist in den Figuren in zwei perspektivischen Ansichten dargestellt.An embodiment is shown in the figures in two perspective Views shown.

Figur 1 zeigt ein Anlageteil 1 (z.B. das Rohr einer Frischdampfleitung im Kernkraftwerk), an das eine aus der Isolation herausragende Lasche 2 angeschweißt ist.Figure 1 shows a system part 1 (e.g. the pipe of a live steam line in the nuclear power plant), to which a tab 2 protruding from the insulation is welded is.

Mit dieser Lasche 2 ist eine Grundplatte 3 verschraubt, an der ein als würfelförmiges Eisenstück ausgebildetes Führungselement 4 befestigt ist. In dem Führungselement 4 befinden sich zwei zueinander senkrechte Bohrungen, in denen Hülsen 5 und 6 aus austenitischem Stahl gelagert sind. Die Außendurchmesser der Hülsen sind dabei so gewählt, daß sie sich in axialer Richtung in den Bohrungen im Führungselement 4 verschieben können. Um eine federnde Lagerung zu erreichen, ist für Jede Hülse Jeweils eine Zugfeder 7 bzw. 8 vorgesehen, die einerseits an der Hülse 5, 6 befestigt sind und andererseits in einem am Führungselement 4 angeschweißten Haken eingehängt werden. In den Hülsen 5 und 6 sind außerdem Querbohrungen vorgesehen, in die Befestigungsschrauben 9 und 10 hineinragen. Mit Hilfe dieser Befestigungsschrauben sind in den Hülsen Rundhölzer festgeklemmt, die ihrerseits angespitzt sind und an der Spitze Stahlnadeln als Schreibepitze 11 enthalten. Die Verwendung der Rundhölzer ermöglicht eine gute Befestigung der Schreibspitzen und gewährleistet eine gute Wärmeisolation.With this tab 2, a base plate 3 is screwed to which a Guide element 4 designed as a cube-shaped iron piece is attached. In the guide element 4 are two mutually perpendicular holes in which Sleeves 5 and 6 made of austenitic steel are mounted. The outside diameter of the Sleeves are chosen so that they are in the axial direction in the bores can move in the guide element 4. To achieve a resilient mounting, a tension spring 7 or 8 is provided for each sleeve, one on the one hand the sleeve 5, 6 are attached and on the other hand in a welded to the guide element 4 Hooks are attached. Cross bores are also provided in sleeves 5 and 6, protrude into the fastening screws 9 and 10. With the help of these fastening screws logs are clamped in the sleeves, which in turn are sharpened and on the tip contains steel needles as a writing tip 11. The use of round timbers allows a good attachment of the writing tips and ensures a good Thermal insulation.

Durch die Zugfedern 7 und 8 werden die Hülsen 5 und 6 mit den Schreibspitzen 11 der Rundhölzer gegen die Platten 12 und 13 gedrückt. Auf den Platten 12 und 13 ist mit nicht dargestellten Klemmen die Schreibunterlage 14, 15 festgeklemmt. Vorteilhafterweise verwendet man als Schreibunterlage ein mit Kunststoff beschichtetes Papier, auf dem die Schreibspitzen 11 dunkle, nicht auslöschbare Eindrücke hervorrufen können. Die Platten 12 und 13 sind ortsfest auf einem T-Träger 16 befestigt, wie insbesondere aus der Ansicht nach Figur 2 zu ersehen ist. Schlitze 17 und 18 in den Platten 12 und 13 können als Markierungen für den Rand der Schreibunterlagen 14 und 15 dienen. Zusätzlich ist im Plattenwinkel (beim Übergang der horizontalen zur vertikalen Koordinate) eine Bohrung 19 vorgesehen. Hierdurch wird sichergestellt, daß die Schreibunterlage Jeweils die gleiche Lage einnimmt, auch wenn diese Unterlage gewechselt wird.By the tension springs 7 and 8, the sleeves 5 and 6 with the writing tips 11 of the logs pressed against the panels 12 and 13. On plates 12 and 13 the writing pad 14, 15 is clamped in place with clamps (not shown). Advantageously a plastic-coated paper is used as a writing pad which the writing tips 11 can produce dark, indelible impressions. The plates 12 and 13 are fixedly attached to a T-beam 16, such as in particular can be seen from the view according to FIG. Slots 17 and 18 in plates 12 and 13 can serve as markings for the edge of the writing pads 14 and 15. In addition, in the plate angle (at the transition from the horizontal to the vertical coordinate) a bore 19 is provided. This ensures that the Writing pad always takes the same position, even if this pad is changed will.

Verwendet man die beschriebene Meßeinrichtung für Anlageteile, die sowohl statisch durch Temperatureinwirkung, als auch mechanisch belastet werden (dynamische Belastung), so ist es zur leichteren Auswertung der Beßprotokolle vorteilhaft, zunächst die Grundstellung der Schreibspitzen 11 zu markieren, dann die Anlage auf Betriebstemperatur zu fahren und die dann erreichten Stellungen der Schreibspitzen 11 ebenfalls zu kennzeichnen. Jetzt kennt man die statische Bewegung des betreffenden Anlageteiles und kann später bei besonderen Belastungen des Anlageteiles zu Prüfzwecken von der statischen Bewegung die dynamischen Bewegungen unterscheiden.If the measuring device described is used for parts of the system that both statically due to the effect of temperature and also mechanically (dynamic load), it is advantageous for easier evaluation of the biting protocols, first to mark the basic position of the writing tips 11, then the system on To drive operating temperature and then reached the positions of the writing tips 11 must also be marked. Now we know the static movement of the person in question Part of the system and can later be used for testing purposes in the event of particular loads on the part of the system distinguish dynamic movements from static movement.
