Description

Profile rail for monorail overhead conveyors

Description:

The invention relates to a profile rail for monorail overhead monorail in I-shaped embodiment, with a top flange and a bottom surfaces forming the bottom flange, wherein the top flange on its upper side and / or the bottom flange on its underside drive members for interaction with a guided on the bottom flange and / or top flange Drive machine has.

A profile rail of the structure described above is described in the utility model DE 81 16 736 U1. This is about a monorail monorail to carry loads or people. The monorail monorail is equipped with the relevant profile rail and at least one marshalling trolley or generally an engine. The shunting trolley or drive machine engages with at least one support roller in the rail profile. The support roller or the two laterally engaging in profile pockets of the profile rail support rollers are guided on the treads formed by the lower flange.

The profile rail is formed in cross section as a double-T-profile, so it is in I-shaped embodiment. In addition to the support rollers, at least one motor-driven drive roller is additionally provided. The drive roller is designed as a gear. The well-known profile rail has on its underside a rack in which engages the gear. In this way, the known trolley or drive machine is not only performed on the profile rail, but this also uses the profile rail for their drive.

The associated drive members for interacting with the drive motor guided on the lower flange and / or upper flange can be provided continuously on the profile rail. But it is also possible that the profile rail is equipped with the drive members in question only in sections. A rail track constructed from profile rails can be continuously equipped with the above-described profile rails, ie. H. with such profile rails, each having drive links for interaction with the prime mover. But it is also possible to equip only a few selected profile rails of the rail track accordingly.

Thus, for example, then worked when the prime mover is typically equipped with drive rollers that are comparable to the idlers in the prior art according to DE 81 16 736 U1 recorded in the rail profile. These drive rollers are friction rollers, ie those which drive the drive machine or trolley on the running surfaces by friction. For curve areas and / or rise areas in such rail tracks, the friction wheels in question are often no longer sufficient for the drive. This is especially true in harsh or wet environmental conditions. Then, for example, the increase can be overcome by means of additional gear wheels and profile rails equipped with corresponding toothed racks.

However, the known profile rails according to DE 81 16 736 U1 encounter limits in this context. Because at this point so-called E-profile rails are used throughout, ie those which are designed in cross-section double-T-shaped, as DE 81 16 736 U1 describes. In addition, reference should be expressly made to document EP 2 276 888 B1 of the Applicant with further references. Such E-profile rails are however with resistance moments in the transverse direction or

Y-direction and those equipped in vertical axes or Z-direction, which does not meet the requirements, especially at high loads (more). In fact, the rails in question are particularly stressed especially in curves and rising areas, exactly where typically the drive on the gears and racks is needed. This is where the invention starts.

The invention is based on the technical problem of further developing such a profiled rail so that increased resistance torques in the transverse direction and / or high axis direction can be expected in comparison with the prior art and thus predestinate the profile rails in question, especially for use in curved areas and rising areas in rail tracks.

To solve this technical problem, a generic profile rail for monorail overhead monorails in the invention is characterized in that the upper flange and / or the lower flange in cross-section U-shaped and in particular V-shaped.

As a rule, the upper flange in question and / or the lower flange has a recess which is pocket-shaped in cross-section. The design is usually made such that the upper flange and / or the lower flange is equipped with each side of the recess arranged U-legs and in particular V-legs. The bag-shaped recess may be arranged in this context for receiving the drive members.

Here, the invention is initially based on the knowledge that a profiled rail with a U-shaped cross-section in the upper flange and / or lower flange increased resistance moments in the transverse direction or Hochachsenrichtung provides. At the moment of resistance acts

it is known to be a size of the technical mechanics, which is derived solely from the geometry of a beam cross-section. The moment of resistance is a measure of what resistance the beam, d. H. in the present case the profiled rail, opposes the generation of internal stresses when loaded in the respective transverse direction or vertical axis direction.

This is true even in the event that only the upper flange is U-shaped, while the lower flange, for example, largely flat on its underside. In this case, the drive links for interacting with the drive machine can be connected to the flat underside of the lower flange.

Nevertheless, the U-shaped design of the U-shaped and opposite upper flange in conjunction with the lower flange and the drive members provided thereon ensures that with a cross-sectional area of about 40 cm ^{2 of} the respective profile rail resistance moments in the transverse direction or Y direction of WY (in cm ³ ) of more than 200 can be achieved. The moment of resistance in Hochachsen- or in the Z-direction is approximately Wz (in cm ³ ) 50 or more. That is to say, moments of resistance are already observed for this special case, as are otherwise only present in profile rails of comparable design, which have both a U-shaped upper flange and a U-shaped lower flange. Reference is made to WO 2010/081719 A1.

This is surprising because in the example described only one flange, in this case the upper flange, is designed in cross-section U-shaped, whereas the underside of the lower flange is largely flat, comparable to an E-profile rail. Nevertheless, already with this

Embodiment observed resistance moments, which correspond to those of profile rails with both U-shaped upper flange and U-shaped lower flange. This can be traced back to the connected to the flat bottom of the lower flange drive links that comparable to the U-legs of the U-shaped upper flange increase the moment of resistance in the transverse direction as well as in the vertical axis direction compared to an E-profile rail.

If, according to the invention, the profiled rail is equipped with both a U-shaped upper flange and a U-shaped lower flange and, in addition, the pocket-shaped recess accommodates the drive members, for example, at the lower flange, resistance moments can be set and observed altogether, those of profile rails with both U-shaped Exceed the upper flange as a U-shaped lower flange without drive links. In fact, resistance moments in the transverse direction or Y direction of WY (in cm ³ ) of greater than or equal to 250 are observed in this case. The moment of resistance in the vertical axis or Z direction is approximately Wz (in cm ³ ) 60 and in particular 70 or more. The aforementioned values again refer to an associated cross-sectional area of about 40 cm ² for the profile rail in question.

In any case, it is clear that the profile rail according to the invention is equipped with the connected drive members for interaction with the prime mover by the U-shaped design of at least one flange with increased resistance moments compared to an E-profile rail. It will usually be done so that the drive links are provided on the lower flange. Of course, this is only an example and is by no means limiting. Because just as well, the upper flange can be equipped with the drive links in principle.

In addition, the design is such that the equipped with the drive links flange on its underside or top can be largely flat or U-shaped, in which case the recess between the two U-legs receives the drive members. The respective opposite flange then has the desired U-shape in cross section.

The drive members protrude in side view of the profile rail according to the invention usually the top flange or bottom flange. Because actually the drive links are regularly realized either only on the upper flange or only on the lower flange. In most cases, the lower flange is equipped with the drive links. The drive members can each be connected individually to the lower flange. Of course, in principle, however, both the upper flange and the lower flange can be equipped with the drive links.

As a rule, one proceeds in such a way that the drive links are arranged on a base rail. As a result, all the drive members can be fixed in one go on the profile rail in question. For this purpose, you will usually adapt the base rail of its length to the profile rail. In addition, the design is regularly made so that the drive links evenly distributed to the base rail and thus the profile rail are connected.

To connect the base rail to the top flange or bottom flange, reference is made to typical joining techniques for metals and especially steel. In fact, the profile rail is usually constructed of a steel with a yield strength of more than 300 N / mm ² .

The same applies to the base rail and the drive links. As suitable joining techniques, the invention recommends, in this connection, a welded connection between the respective drive members or the base rail carrying the drive members and the associated profile rail.

If the profile rail according to the invention is designed U-shaped at its upper flange in cross-section, while the lower flange is connected on its largely flat bottom with the base rail, it is usually proceeded so that the longitudinal extent of the profile running rail following base rail on both sides linear with the underside of the lower flange is connected. Of course, the base rail can also be selectively coupled at its two sides with the mostly flat bottom of the lower flange in the example case.

In this case, in both cases, the procedure will be such that the respective welding bead is usually arranged in the region of the base rail, so that the drive members standing on the base rail are available for interaction with a drive wheel on the drive machine.

If the upper flange and the lower flange are each U-shaped in cross-section, the drive members are usually placed in the pocket-shaped receptacle in the lower flange. For this purpose, the base members carrying the drive members can be arranged in the pocket-shaped receptacle of the lower flange in question. In addition, the base rail in question is connected to the two-sided U-legs. In principle, the drive members or the base rail with the drive members can also be placed in the pocket-shaped receptacle of the upper flange. As a general rule

However, the drive links and with it the base rail are fixed to the bottom flange.

When connecting the base rail with the U-legs of the U-shaped lower flange on both sides, it is generally the case that the base rail bears against a base of the recess in the inside of the pocket-shaped receptacle in question. In this case, usually not the base rail is connected to the question U-legs of the U-shaped base flange. Rather, usually provide the upstanding on the base rail drive members for the coupling with the respective U-leg.

That is, the base rail is connected in this case only in the region of its upper side arranged drive links with the two-sided U-legs. The coupling is carried out regularly at points by welding points, which are generally set on both sides of the respective drive link. As a result, the respective intermediate space between the individual and mostly equally spaced drive members for the engagement of the drive wheel of the drive machine is available. Since it is at this point in the drive members mostly teeth and the base rail to a rod and consequently a total of a rack, this ensures that the drive wheel or gear can properly intervene in the spaces between the individual teeth respectively drive links. Because the drive members are only on both sides and selectively connected to the respective adjacent U-legs in the pocket-shaped recess of the U-shaped lower flange. In the area of the respective intermediate spaces between the individual tooth flanks, therefore, no weld bead or otherwise a weld point is present. This allows the drive wheel or

Gear of the drive machine properly engage in the interstices and interact with the formed as tooth flanks drive links.

In addition, the installation of the base rail at the base of the recess in the interior of the pocket-shaped receptacle means that an available and conventional so-called V-profile rail according to WO 2010/081719 A1 does not have to be reworked or hardly reworked in the region of the recess in question. In particular, this material losses are avoided. On the contrary, the bottom rail adjacent to the bottom of the recess acts as if it were a bridge between the two U-legs or V-legs. This leads to the already described significant increase of the moment of resistance in both the transverse direction and in the vertical axis direction in comparison to a profile rail comparable structure without additional drive links or connected rack.

Finally, it has been proven that the base rail carrying the drive members has a width which is approximately 0.5 to 0.7 times a flange width of the flange supporting the base rail. By this design rule, the invention ensures that on both sides of the base rail there provided weld beads or weld points for coupling with the associated flange are available. On the other hand, this interpretation takes into account that the running on the running surfaces of the lower flange rollers of the prime mover on both sides of an intermediate I-bar have a comparable material thickness as the gear or drive wheel.

Since the drive members or the base rail with the drive members mounted thereon respectively the rack in extension of the question I-

Bridge is usually connected to the lower flange, describe the two wheels together with the drive wheel in side view of an (isosceles) triangle. The triangle has a base of the two wheels and is designed at the top with the meshing with the rack drive wheel. As a result, in this area, widths of the base rail are sufficient, which corresponds approximately to half or a little more to the width of the base of the two wheels and consequently to running surfaces.

As a result, a profiled rail for monorail overhead conveyors is made available, which can be used particularly advantageously in a rail track in the area of curved sections or in ascending areas. Because there is often an additional drive or engagement between a drive wheel of the prime mover and carried by the relevant profile rail drive members required for mutual interaction. Since high loads of the relevant profile rail are observed in these areas, the profile rail according to the invention has in comparison to the prior art via a respective increased resistance moment, both in the transverse direction and in the vertical axis direction.

The invention achieves this by the combination of on the one hand the drive members connected to the profiled rail and, on the other hand, the U-shaped profile of the flange opposite the drive members. Here are the main benefits.

In the following, the invention will be explained in more detail with reference to a drawing showing only an embodiment. Show it:

1 and 2,

Invention,

Fig. 5 is a side view of the article of FIG. 4 and

Fig. 6 shows the object according to Figures 4 and 5 in a perspective.

In the figures, a profile rail for single-rail monorails in I-shaped embodiment is shown. In the exemplary embodiment of FIG. 4, two monorail rollers 1 and, in addition, a drive wheel 2 can be seen from the monorail monorail conveyor. The two track rollers 1 serve to guide a drive machine 3, which is merely indicated, to the profiled track in question. The two rollers 1 can be driven or driven. In the case of the drive wheel 2, in the example case, it is a gearwheel 2 which interacts with a toothed rack 4, 5 for the propulsion of the drive machine 3 or drive members 4 generally mounted on a base rail 5.

The respective profile rail in I-shaped embodiment has an upper flange 6 and a lower flange 7. The lower flange 7 forms running surfaces L, on which in the example the rollers 1 of the drive machine 3 are guided along the lower flange 7. That is, the prime mover

3 is performed in the example on the lower flange 7, but can also learn both the lower flange 7 and 6 on the upper flange the required guidance. The upper flange 6 and the lower flange 7 are connected to each other via an I-web 8. On both sides of the I-bridge 8, the rollers 1 of the drive machine 3 are arranged. The same applies to the associated running surfaces L of the lower flange 7. In the context of both embodiments according to Figures 1 to 3 or 4 to 6 respectively of the lower flange 7 is equipped with the already mentioned drive members 4. The flange of the drive members 4 opposite, in this case the upper flange 6, in contrast, and compulsorily in cross section has a U-shape. In particular, even a V-shaped cross section is observed.

In fact, in the embodiment of Figures 1 to 3 of the local upper flange 6 in cross-section U-shaped equipped with U-legs on both sides 6a and a central pocket-shaped recess 6b. In contrast, the lower flange 7 in this embodiment has a largely flat bottom. In the embodiment, a base rail 5 is connected to the largely flat bottom of the lower flange 7, in this case welded to the underside of the lower flange 7 in question. On the base rail 5 are the drive members 4, which is in the embodiment to tooth flanks 4. Consequently, the drive members or tooth flanks 4, in conjunction with the base rail 5 carrying them, as a whole define the already mentioned rack 4, 5.

It can be seen that in the embodiment according to FIGS. 1 to 3, the base rail 5 is connected on both sides linearly with the underside of the lower flange 7. At the top of the lower flange 7, the already described running surfaces L are formed, which carry the rollers 1 of the drive machine 3 and lead. For the two-sided linear connection of the base rail 5 with the lower flange 7 provide in the embodiment of Figures 1 to 3 respectively continuous and visible in the embodiment of welding beads 9, which are shown partially hatched. These weld beads 9 are adapted by their material thickness to the width or material thickness of the base rail 5 or do not exceed this, so that the drive members respectively tooth flanks 4 are free of the respective weld beads 9.

1 to 3 as well as the corresponding side view of Fig. 5 in the second embodiment according to FIGS. 4 to 6 clearly that the drive members 4 respectively tooth flanks 4 of the rack 4.5 each project in side view the sub-flange 7. As a result, the gear 2 of the drive machine 3 can interact properly with the tooth flanks 4 and engage in the spaces 10 formed between the tooth flanks 4. This also applies to the embodiment of FIGS. 4 to 6.

In fact, in this case, it can be seen from the cross-sectional illustration in FIG. 4 that both the upper flange 6 and the lower flange 7 are U-shaped or V-shaped in the present case. That is, both the upper flange 6 and the lower flange 7 have in the second embodiment according to FIGS. 4 to 6 on each side U-legs 6a and 7a, respectively, which receive between each pocket-shaped recess 6b and 7b.

In the context of the embodiment according to FIGS. 4 to 6, the pocket-shaped recess 7b on the lower flange 7 for receiving the drive members 4 and the rack is set up 4.5. For this purpose, the base rail 5 is received in the pocket-shaped recess 7b of the U-shaped lower flange 7. In addition, the base rail 5 or the individual drive members or tooth flanks 4 are connected to the two-sided U-legs 7a. The coupling of the base rail 5 with the lower flange 7 is carried out in the embodiment of Figures 4 to 6 so only in the upper side of the base rail 5 arranged drive members respectively tooth flanks 4 with the two-sided U-legs 7a of the lower flange. 7

In particular, with reference to the perspective view in FIG. 6, it can be seen that, for this purpose, the respective tooth flanks or drive members 4 are connected to the adjacent U-limb 7a of the lower flange 7 on both sides and at points in the context of spot welds 9 ^' . In addition, it can be seen that the base rail 5 is in this variant at the bottom of the pocket-shaped recess 7b on the lower flange 7. In this case, the base rail 5 acts together with the drive members worn by it respectively tooth flanks

4 as a bridge between the two U-legs 7a. Finally, the overall design is such that the base rail

5 has a width Bi, which is approximately 0.5 to 0.7 times a flange width B2 of the base rail 5 bearing flange, in the embodiment of the lower flange 7. The flange width B2 of the lower flange 7 corresponds to that flange width B2 of the upper flange 6.

In addition, the flange width B2 of the lower flange 7 is largely composed of the two running surfaces L for the rollers 1 of the engine 3. It can be seen that the two rollers 1 of the drive machine 3 arranged and guided on both sides of the I-bar 8 are arranged symmetrically in comparison to the central I-bar 8. On the symmetry axis, the base rail or rack 4, 5 is placed. As a result, the two rollers 1 and the drive wheel 2 clamp an (isosceles) triangle, so that the drive forces applied by the drive wheel or gear 2 in interaction with the profile running rail are introduced centrally into the work machine 3 or centrally from the profile rail be transmitted.
