Abstract

The invention relates to a device for Druckuebertragung or defined introduction of force acting on the upper Laengstraeger compressive forces in the transport of large transformers with Brueckenkesseln, which is hooked even as a supporting bridge construction in the transport unit. The aim is an optimal design of the boiler by introducing the compressive forces in a specific position and distribution for all load situations. This is realized by the use of an adapter at the upper connection points between the transformer tank and the support bar. The adjusting element consists of a sliding and pressure part, which are formschlüssig on the same or ungeleichgekruemmte surfaces together. The slide is forcibly guided on the side and can be adapted to the position of the support beak by means of a setting device and locked by a locking device in its position. Fig. 1

Device for transmitting pressure to transformer bridge boilers

A pplication Field of the Invention :.

The invention relates to a device for pressure transmission or defined initiation of the pressure forces acting on the upper side members during the transport of such large transformers, the boiler of which (so-called bridge boiler) itself is suspended as a load-bearing bridge construction in the transport unit front-end bridge boiler.

Characteristic of known technical solutions :

It is known that by the type of suspension of the transformer in the bridge tank between the front and rear cars on the lower side members on the suspension bolts tensile forces and on the upper side members

Compressive forces are transmitted "This results from the mass distribution and additional transport stresses. In order to absorb the tensile or compressive forces which predominantly result from the bending moment and which act in the longitudinal direction of the boiler, tension or compression straps have hitherto been attached to the side walls of the boiler. The upper yoke of the iron core of the transformer itself also increased to increase the resistance moment exploited as a pressure belt (DE-PS 1946 706) ·.

It is also known that through the pivot point "Einhängebolzen" is a defined point of attack, while in rigid pressure distribution plates at the top of the trolley depending on the load situation, the center of pressure center in non-definable height »(DE-PS 2103 315) ·. 'iür the optimal design of the bridge boiler, in particular the upper side member but that is of great disadvantages

Object of the invention:

The invention aims an optimal design of the bridge boiler.

, Explanation of the essence of the invention:

The invention has for its object to ensure the initiation of compressive forces in a particular location and distribution, so that the bridge boiler can be optimally designed for all stress situations »

According to the invention, the object is achieved by the use of an adapter element at the upper connection points zv / ischen transformer tank and support bar. This adapter is able to cause a defined force introduction and distribution regardless of the respective loads and possible changes in shape of the transformer boiler and / or the trolley. For this purpose, the adapter member consists of a carriage-side sliding part and a transformer-side pressure part, wherein the sliding part by

arranged on the pressure part lateral guides is forcibly guided. By adjusting the sliding member is adjustable in its inclination to the pressure piece of the _t supporting beak and detectable in its position by a Peststellvorrichtung. The form-fitting contacting surfaces of the slide and the pressure member may be the same or not curved.

The inventive design, it is possible to minimize the boiler parts that need to absorb the pressure forces (generally longitudinal beams), in shape, cross-section and mass. In addition, all uncertainties with regard to the height-variable off-center loads of the loaded sections are eliminated.

Embodiment.

The invention will be explained in more detail below using an exemplary embodiment:

In Fig. 1, the front half of a TranSportwagens and the transformer is shown. The transformer hangs between the front trolley half (front) and the rear trolley half (rear, trolley) by being coupled with the support bolt 3 by means of the suspension bolts V and is supported against the support bar 2 at the pressure transfer point.

The same curvature of the positive surfaces present on the sliding and pressure part ensures a specifically uniform force transmission in every position; at different curvatures, a force centering, for example, on the Mitt.enachse of Druckträ ^ ers done - at entsnrechender Ausleeiune:
