Description

Aufhängung von Wasserrohrkesseln. Im Patent 435 411 ist gezeigt, wie man einen Wasserrohrkessel an quer zu seiner Längsachse angeordneten Waagebalken. aufhängen kann.Suspension of water tube boilers. In patent 435,411 it is shown how a water tube boiler on balance beams arranged transversely to its longitudinal axis. can hang up.

Die Erfindung betrifft eine solche Aufhängevorrichtung und hat zum Ziel, die Waagebalkenaufhängung so auszugestalten, daß die Kesseltrommel sich um ihre Längsachse drehen kann, ohne daß sie die geringste Verschiebung senkrecht zu ihrer Längsachse in irgendeiner Richtung erfährt. Die Trommel behält also, abgesehen von ihrer Drehung, ihre Lage bei.The invention relates to such a suspension device and has to The aim is to design the balance beam suspension so that the boiler drum turns around its longitudinal axis can rotate without it being the slightest displacement perpendicular to it experiences its longitudinal axis in any direction. So apart from that, the drum holds up of their rotation, their location at.

Die Erfindung ist in der Zeichnung in einfachen Linien dargestellt. Die Trommel a hängt mittels der Stangen r an dem Waagebalken s. Die Anfaßpunkte t und u der Stangen r an der Trommel a bilden mit denn. Mittelpunkt v der Trommel ein gleichschenkliges Dreieck, und die Einrichtung ist so getroffen, daß die Tragpunkte w und x des Waagebalkens s mit dem Unterstützungspunkty desselben ein ebensolches Dreieck bilden, das mit dem ersteren Dreieck gleichgerichtet liegt. Es ist also das Dreieck t v u kongruent dem Dreieck w y x, und beide Dreiecke liegen gleichgerichtet übereinander, derart, daß die Seiten t u und w x parallel sind und. daß die Spitzen v und y nach derselben Richtung hin liegen. Bei einer solchen Ausbildung des Waagebalkens kann die Trommel a sich um die durch den Mittelpunkt v gehende Längsachse beliebig drehen, ohne äaß die Längsachse ihre Lage im Raum verändert.The invention is shown in the drawing in simple lines. The drum a hangs on the balance beam s by means of the rods r. The gripping points t and u of the rods r on the drum form a with then. Center v of the drum is an isosceles triangle, and the device is made so that the support points w and x of the balance beam s form a triangle with the support point y of the same, which is aligned with the former triangle. The triangle tvu is therefore congruent to the triangle wyx, and both triangles are aligned one above the other, in such a way that the sides tu and wx are parallel and. that the tips v and y are in the same direction. With such a construction of the balance arm, the drum a can rotate as desired about the longitudinal axis passing through the center point v without the longitudinal axis changing its position in space.

Durch die dargestellte Ausbildung des Waagebalkens wird jede durch im Kessel gelegene Ursachen bewirkte Lagenänderung der Obertrommel widerstandslos aufgenommen, so daß alle aus unrichtiger Aufhängung entstehenden Beanspruchungen .innerhalb des. Kessels fortfallen. Diese Beanspruchungen können unter Umständen sehr erheblich werden, und sie greifen in der Regel an dem schwächsten Teil des Kessels an, das sind die Rohreinwalzstellen, die durch fortwährende Zug- und Druckbeanspruchungen, verbunden mit Biegungsbeanspruchungen der Rohre, gelockert werden.The illustrated design of the balance arm is each through Causes located in the bowl caused a change in the position of the upper drum without resistance added, so that all stresses arising from incorrect suspension .within the. boiler. These stresses can under certain circumstances become very significant, and they usually target the weakest part of the Boiler, these are the pipe roll-in points, which by continuous tensile and compressive loads, associated with bending stresses on the pipes.

PATENTANSPRUCH: Quer zur Längsachse des Kessels angeordnete Kesselaufhängung nach Patent 43 5 411, dadurch gekennzeichnet, daß der Drehpunkt (y) des Waagebalkens (s) und die beiden Anhängepunkte (w, x) für die Kesseltrommel (a) ein Dreieck bilden, welches kongruent und gleichgerichtet ist dem Dreieck aus dem Mittelpunkt (v) des Kessels und den beiden Anfaßpunkten (t, u) für die Aufhängevorrichtung. Claim: Boiler suspension arranged transversely to the longitudinal axis of the boiler according to patent 43 5 411, characterized in that the pivot point (y) of the balance beam (s) and the two attachment points (w, x) for the boiler drum (a) form a triangle which is congruent and in the same direction is the triangle from the center (v) of the boiler and the two gripping points (t, u) for the suspension device.
