Definitions

• the invention relates to a rail track for particular monorail monorails, with one or more profile rails, which are coupled to each other by at least one hinge joint, wherein the respective profile rail has a top flange and a bottom flange.
• Such a rail track is described by way of example in the utility model DE 297 03 939 U1.
• Comparable rail tracks are known in large numbers and design from practice. A requirement for such rail tracks is that the at least one articulated connection must absorb certain longitudinal forces. Such longitudinal forces are then set or can occur when monorail overhead conveyors move over the profile rails and use them for power transmission. For this reason, in the meantime, different joint connections as well as different rail profiles have been developed. For example, there is a so-called "V-rail" of the applicant, which is characterized by a particularly high resistance moment (see DE 296 04431 U1).
• a generic rail track for particular monorail monorails in the context of the invention is characterized in that the articulated connection has a minimum cross-section of at least 6cm 2 , in particular at least 7 cm 2 .
• the articulated connection has a minimum cross-section of at least 6cm 2 , in particular at least 7 cm 2 .
• E-rails or standard rails working mostly with in cross-section I-shaped profile rails, so the already mentioned so-called E-rails or standard rails.
• the V-rails according to DE 296 04 431 LM are not excluded.
• both an upper and a lower hinge connection are provided.
• the lower hinge connection is equipped with the minimum cross section of at least 6 cm 2 in question, because usually the upper articulated connection has a larger cross section at this point. That is, for the occurring longitudinal forces, the lower joint connection is the crucial test site.
• this lower joint connection is now their minimum cross-section with a size of at least 6cm 2 equipped. Usually the size of the minimum cross-section of the lower hinge connection is at least 7 cm 2 .
• the fact that the articulated joint (and regularly also the profile rail as such) each made of a steel with a yield strength of at least 300 N / mm 2 is equipped, can be easily taken by this design rule longitudinal forces of 140 kN or even more.
• the yield strength of the steel for the production of the lower joint can also be above 350 N / mm 2 .
• a force of about 180 kN is calculated from these specifications until the yield strength is reached.
• longitudinal forces of about 140 kN can be easily absorbed.
• the single articulation or the lower articulation defines an axis of rotation for authorized pivoting movements between the respective adjacent profile rails.
• the axis of rotation is located outside of a separation area.
• This separation area or impact area marks the gap area between the profile rails, which is delimited by the upper flange and the lower flange or its upper edge and lower edge.
• the state of the art for example according to DE 297 03 939 U1, works at this point with an axis of rotation which is located at the lower edge of the separating area or in or at the lower flange.
• the axis of rotation is now displaced outside this separation area.
• the axis of rotation can be arranged below a lower edge of the profile rail.
• the axis of rotation it is also conceivable for the axis of rotation to be offset in the longitudinal direction of the profiled mounting rails in comparison to the separating area.
• the invention pursued offset of the axis of rotation ensures that acts on the profile rails longitudinal force acts on both the upper hinge connection and the lower hinge connection, if two such joints are realized, which is usually the case.
• the special arrangement of the hinge axis outside of the separation area ensures that the particularly loaded lower hinge connection is not unintentionally opened even with an inclination of the profile rails in the joint area between adjacent profile rails.
• any plastic deformations on the lower hinge connection are prevented by the displacement of the axis of rotation - even in the described skewing of the profile rails.
• Such an inclination of profile rails occurs in practice quite well and is common because due to movements underground and the expansion moves to attach the profile rails and can lead to an offset of the profile rails against each other.
• the displacement of the axis of rotation, in particular below the lower edge of the profile rail ensures that acting on the axis of rotation longitudinal forces are absorbed directly by the practically arranged at the same height lower hinge connection, without acting on this hinge connection torques of the shape that it is opened unintentionally ,
• the axis of rotation is offset in the longitudinal direction in comparison to the separation area.
• an arrangement on the lower edge of the respective profiled mounting rail has proven to be favorable, wherein the offset in the longitudinal direction in comparison to the separation area at a few millimeters, for example 5 mm or 10 mm, is located. Comparable values are observed for the offset of the axis of rotation below the lower edge of the profile rail.
• the invention recommends to work with a shackle.
• a shackle This can be a fork shackle or a Y-shackle with two connection points to fix on the expansion.
• the respective shackle connects respective bearing cheeks to each other on the upper flange of the adjacent profile rails.
• the bearing cheeks are usually designed so that they each bridge the joint area or separation area between adjacent profile rails.
• a rail track which is usually composed of at least two profile rails with associated upper and lower hinge connection.
• the invention is based on the fact that longitudinal forces of up to 140 kN can be easily transferred if the articulated connection or the lower joint connection is equipped with a minimum cross section of at least 6 cm 2 . Because in such a case, at least fourfold security against breakage failure is given in connection with the upper joint.
• the design of the minimum cross-section of 6 cm 2 in conjunction with the use of a steel with a yield strength of at least 300 N / mm 2 ensures that the lower joint alone can absorb forces up to the yield strength of 180 kN.

• FIG. 2 shows a modified embodiment according to FIG. 1,
• FIG. 3 shows the embodiment of FIG. 1 in a front view of the
• FIG. 4 is a similar view as in Fig. 3,
• FIG. 6 shows an alternative embodiment according to FIG. 5.
• a rail track for monorail overhead conveyors is shown, ie one which is driven by a monorail overhead conveyor with trolley and possibly attached trailers.
• the rail track is composed of several profile rails 1, which are coupled together in the embodiment by two joints 2, 3.
• a lower hinge 2 and further an upper hinge 3 is realized.
• the profile rails 1 have a top flange 4 and a running surfaces 6 for the monorail conveyor having sub-flange 5. Man recognizes that the treads 6 are slightly inclined to center the monorail conveyor with the rollers guided on it as they travel.
• the profile rails 1 have an I-shaped cross-section, so are designed according to the preceding explanations as E-rails.
• the lower hinge connection 2 has a minimum cross section Q to be recognized in FIGS. 5 and 6, which is at least 6 cm 2 in size.
• a cross-section Q of about 9 cm 2 observed whereas the cross-section in the context of the variant of FIG. 6 is about 7 cm 2 .
• the upper hinge joint 3 at this point has significantly larger cross-sections, because they generally in acting on the profile rails 1 longitudinal forces as indicated by arrows in Fig. 1, receives a majority of these longitudinal forces.
• the lower hinge joint 2 defines an axis of rotation D for permitted pivotal movements between the adjacent profile rails 1, which is located outside of a separation area or impact area T.
• this separation area T extends between the two adjacent profile rails 1 and thus coincides with a joint area.
• the separation region T is bounded in each case by the lower edge of the lower flange 5 and the upper edge of the upper flange 4, thus extending over the entire length of the I-shaped profile of the profile rails, in their gap region.
• the total of the two articulated joints 2, 3 defined pivot axis D for pivotal movements between the adjacent profile rails 1 - in contrast to the prior art - not located in this separation area T, but rather outside thereof.
• the said axis of rotation D has a longitudinal offset L in comparison to the separating region T, which in the present case may be in the range of approximately 5 mm or even more.
• the axis of rotation D is below the lower edge of the lower flange 5 and has at this point a transverse offset V, which is usually also settled in the millimeter range.
• the upper hinge joint 3 is manufactured and fixed. Following this, the adjacent profile rail 1 is pivoted by connecting the lower joint 2 to the adjacent profile rail 1. Since the upper articulated connection 3 generally has a shackle 7 which is bolted to bearing cheeks 8, or otherwise connected, there is the danger, in particular in the area of the lower articulated connection 2, that this is opened when longitudinal forces occur and / or deforms ,
• the lower hinge connection 2 has a pivot bearing cam 2a with a T-shaped pivot bearing head 2b, which engages in a corresponding pivot bearing head receptacle 2c of a pivot bearing pocket 2d on the adjacent profile rail 1.
• the pivot bearing head receptacle 2c is T-shaped.
• the invention recommends the recourse to the already mentioned shackle 7, which is executed in the context of FIG. 1 as a fork shackle or may also be in the form of a Y-shackle of FIG.
• the said shackle 7 ensures that respective bearing cheeks 8 are connected to each other at the adjacent profile rails 1 in the region of the upper flange 4.
• these bearing cheeks 8 are designed so that they each bridge the joint area or the separation region T between the adjacent profile rails 1, as in particular the front view of the make according to FIGS. 3 and 4 clearly.
