Description

ROLLER RAILING PROFILED FOR RAILWAYS SUSPENDED MONORRAÍL FIELD OF THE INVENTION The invention relates to a profile rail for monorail suspended railways, in the form of an I-shaped embodiment, with an upper head and a lower head forming the running surfaces, in which the upper head has on its upper side a pocket-shaped recess in cross section, forming a U-shaped upper head, and in which the lower head has a pocket-shaped recess in its cross-section on its underside, forming a substantially U-shaped lower head inverted with the running surfaces formed by the U-base on both sides of an I-core.

BACKGROUND OF THE INVENTION I-shaped profile rails are known for monorail suspended railways, in which the upper head and the lower head are configured as solid heads. Similar embodiments are proportionally heavy with a view to weight, in particular if the profiled rails are to be used as rails for heavy loads and therefore must have corresponding dimensions for reasons of stability. It is added that the suspension devices arranged on the side of the upper head at the ends of the rail and the articulated rail connections arranged on the side of the lower head must be welded on the upper side of the upper head or the lower side of the head. the lower head, so that a proportionally cantilevered construction mode must be assumed in the area of rail joints, which frequently does not it can be carried out at least in the lower head, since the rolling carriages running underneath need a sufficient clearance against the lower side of the lower heads and therefore interfere with the rail connection.

A profiled rail of the embodiment described at the beginning is known from the industrial utility model DE 296 04 431 U1. Here, it is primarily a matter of providing sufficiently high moments of resistance in a compact construction mode, taking into account a weight minimization. This has basically proven its effectiveness, however, it can be improved with a view to a repeated increase in the moments of resistance.

BRIEF DESCRIPTION OF THE INVENTION The invention is based on the technical problem of developing a profile rail with the structure described at the beginning, so that greater moments of resistance with a structure that is simultaneously compact are contemplated again.

In the context of the invention, for the solution of this technical problem, it is provided in the case of a generic profile rail for monorail suspended railways that the ratio of the rail width to the height of the rail is established in the range of about 0.2 to 0.6.

Using this rule in the dimensions ensures that the width of the rail is at least about one fifth of the height of the rail and is designed to a maximum of approximately half the height of the rail or something above. For this reason, particularly high moments of resistance can be contemplated, both in the transverse direction and also in the direction of the vertical axis. Furthermore, the design has mostly given that the upper head and the lower head are respectively essentially identical in configuration with lateral edges aligned with each other.

That is to say, the profiled rolling rail has an embodiment with mirror symmetry compared to its vertical axis. In addition, it has proven effective that the upper head and / or the lower head respectively have or define a rail width of approximately 60 mm to 80 mm. In addition, the distance between the upper head and the lower head and the height of the resulting rail can be set in the range of approximately 150 mm to 250 mm.

These measures of the invention have as a consequence overall that, in comparison with the I-shaped profiled rolling profiles hitherto, considerable weight reduction is achieved due to the pocket-shaped notches. However, the forked or U-shaped configuration, both of the upper head and also of the lower head, ensures that high moments of resistance are contemplated against in particular flexions in the transverse direction and in the direction of the vertical axis. This results in reduced manufacturing costs and easy handling during rail assembly. Therefore, according to the teachings of the invention, an advantageously rolled steel profile with a forked upper head and an inverted forked lower head having a high resistance moment and an optimized weight torque is available.

These advantages can be optimized because according to the invention the lower head also has on its lower side the pocket-shaped recess in cross section, forming a lower head substantially inverted in a U-shape with the running surfaces formed by the U-shaped base both sides of the soul in I. In this sense, according to the teaching of the invention, a rolled steel profile with a forked upper head and an inverted inverted lower head is available.

Other essential features in the invention are set forth below.

Thus the invention teaches that the pocket-shaped notch in the upper head is arranged in the upper head for the partial accommodation of suspension elements of a suspension device, which is located at the rail ends. Furthermore, the invention recommends that the pocket-shaped notch be arranged in the lower head for the partial housing of articulated parts of an articulated rail connection, which is also found at the rail ends. In this way, a particularly compact construction mode can be carried out, since the rail suspension and articulated connection is lowered in the area of the rail seal at least partly on, on the one hand, the upper head and, on the other hand, on the other hand. , the lower head and there you can weld unbeatable. Therefore the lower head can be driven underneath without problems by the trolley. - For the increase of moments of resistance, the invention also recommends that the U-shaped upper head * and the U-shaped lower head have U-shaped arms that extend conically against the U-shaped base of their heads.

For the manufacture of the profile rail in question, a steel profile is laminated, preferably a so-called flat steel in width. It has an elastic limit of more than 300 N / mm2, preferably even an elastic limit of more than 350 N / mm2. - The rolling of the flat steel, in particular the flat steel in the width, is carried out in such a way that one or several rolling units machine a flat steel bar at the same time or successively. Four rolling units can be used together altogether. These four rolling units can simultaneously or successively machine the flat steel bar mentioned. Completely apart from this, the steel profile can be laminated in a work cycle. Naturally, several work cycles are also possible and are understood by the invention.

The four rolling units are arranged in this context respectively opposite in relation to the web in I and at the same time in opposition to the upper head and the lower head. That is, two opposing lamination units form the core in I, while the other two lamination units are concerned, on the one hand, with the formation of the lower head and, on the other hand, with the formation of the head higher. For this reason, the rolled steel profile and consequently the described profile rail can be manufactured particularly economically and at the same time precise and with high manufacturing accuracy and speed.

Consequently, the invention also relates to the use of a similar rolled steel profile for the manufacture of the profiled rail. In this respect, a flat steel bar is used as the starting material for the described rolling process, and from a steel with the elastic limit described. As a result, a profiled rolling rail with high mechanical stability and high moment of resistance is provided, which can also be produced inexpensively and in a certain way once from a flat steel bar. In this respect, the steel used is not even given especially large requirements, since the elastic limit in general is set above 350 N / mm2, however, most of the time it is also below 400 N / mm2 . Consequently conventional steels can be used economically.

The moment of resistance reached and increased with respect to the current state of the art expresses that the profiled rail according to the invention can be seen in the direction of the teaching of the manufacture finally as a beam with a given cross section. This beam now generates a determined resistance, the moment of resistance that opposes a bending process or a bending moment associated with it, which acts on the beam in question or the profiled rail. Thus, for the profile rail according to the invention, moments of resistance in the transverse direction or Y direction of WY (in cm3) > 200. The resistance moment on the vertical axis or on the Z axis is approximately Wz (in cm3) 50 or more. These values refer to a corresponding cross-sectional area of approximately 40 cm2 for the profile rail in question.

BRIEF DESCRIPTION OF THE DRAWINGS The invention is explained in more detail below by means of a drawing representing only one embodiment; show: FIG. 1 shows sections of rolling tracks profiled according to the invention in side view, with a suspension device that passes through its joint area on the side of the upper head and articulated rail connection that projects on the side of the lower head and 2 shows a vertical cross section through a profiled rail according to the invention.

DETAILED DESCRIPTION OF THE INVENTION A profiled rail 1 for a monorail suspended rail is shown in the figures. This profiled rolling rail 1 has an I-shaped cross section with an upper head 2 and a lower head 3 forming rolling surfaces 4. The upper head 2 has on its upper side a pocket-shaped notch 5 in cross section , forming an upper head 2 essentially forked or U-shaped. The lower head 3 has on its underside a pocket-shaped recess 6 in cross-section, forming a lower head essentially forked or in the form of an inverted U with surfaces of rolling 4 formed by the U-base on both sides of a soul in I 10. The pocket-shaped recess 5 in the lower head is arranged for the partial accommodation of suspension elements of a suspension device 7 at the ends of the rail. The pocket-shaped recess 6 in the lower head 3 is arranged for the partial housing of articulated parts of a rail connection 8 articulated at the ends of the rail.

The U-shaped upper head 2 and the U-shaped lower head 3 have U-shaped arms 9 which extend conically on the inner side against the U-base. The profiled rolling rail 1 according to the invention is a steel profile laminate.

Using fig. 2 shows that the upper head 2 and the lower head 3 are respectively essentially identical and have lateral edges aligned with each other, as shown by the connection of lines and points of these lateral edges one below the other. In this respect, the upper head 2, as well as the lower head 3, respectively have a width of the rail B, which is established in the range of approximately 60 to 80 mm. Between the upper head 2 and the lower head 3 a height of the rail H of approximately 150 mm to 250 mm is adjusted.

As a consequence, the ratio of the width of the rail B compared to the height of the rail H is in the range of approximately 0.2 to approximately 0.6. That is, the width of the rail B of the profile rail 1 is at least about one fifth of the height of the rail H. As a maximum the width of the rail B can be approximately half the height of the rail H or even slightly higher (approximately 60%).

Furthermore, FIG. 2 clarifies that the U arms disposed on both sides of the respective pocket-shaped recess 5, 6 in the upper head 2 and lower head 3 have a corresponding and identical width b. In this regard, width 2 · bi composed of the two U-shaped arms 9 both of the upper head 2, as well as of the lower head 3, that is, 2 · bi is approximately as large as the width b2 of the corresponding notch 5, 6 in shape pocket-size. That is, it is fulfilled:
