Description

The present invention relates to a tongue device according to the preamble of claim 1 and a method for producing a tongue device according to the preamble of claim 14.

Such tongue devices are used in particular but not exclusively in grooved rail turnouts. They have a stock rail, a Beischiene and a tongue, with a tongue bed for the tongue, on which the tongue can slide without separate lubricant.

There are tongue devices are known which are welded together in individual profiles, wherein the stock rail and used as Beischiene steel profile are connected by means of a high-strength steel plate, the tongue is slidingly movable on this steel plate as a sliding plate. The stock rail and the Beischiene are welded on a base plate. The heater is located in the cavity between the sliding plate and the base plate. By build-up welding at the wear points, individual areas can be solidified, but this is very costly. Overall, this construction is thus very complex.

In order to reduce the manufacturing tolerances and to make the production less complicated overall, is from the DE 40 11 523 A1 already the production of the entire tongue device in a monobloc construction of a single steel block (blank) known by the upper side is machined by milling so that the required contour for the support and installation of the tongues is made. Since the blanks for the monoblock can not be made in the desired height in the full height, here either restrictions in this regard are necessary or it will be applied at least on the tongue bed additionally thin, high-strength support plates in the form of sliding plates. This production is therefore very expensive and therefore uneconomical.

In addition, in the effort to be able to use the industrially manufactured high - strength steel plates and steel billets for the switch construction, constructions of sub - blocks and the use of the high-strength material proposed only for the ZV upper part, while for the sub-component simple structural steels or continue the known, welded from individual profiles, sub-components are used.

For example, the shows DE 10 2010 037 110 A1 a modified structure. Due to this structure, however, the construction is very complex.

The DE 101 24 624 C2 shows, however, a so-called Biblock structure, in which a lower part is made as a unitary block of structural steel. However, this structure is associated with high replacement costs due to the integral structure of the upper part in case of maintenance.

Furthermore, in DE 690 01 072 T2 and DE 199 20 858 A1 proposed a solution in which Beischiene and a part of the base of the tongue device are made in block construction and the side of the stock rail is attached thereto. In this case, the need for a stable non-positive connection of the partially machined rail profiles with the sub-blocks turns out to be a problem.

The object of the present invention is to provide a tongue device which has a high durability, the production costs and the manufacturing costs being as low as possible. In particular, the maintenance costs should be low.

This object is achieved with the tongue device according to the invention according to claim 1 and the method according to the invention for producing a tongue device according to claim 14. Advantageous developments are specified in the subclaims and in the following description together with the figures.

The inventor has recognized that the stated object can be achieved in a surprisingly simple and cost-effective manner that the lower part of the tongue device is constructed together with the tongue bed as an integral part in the form of a basic block, in particular of a steel high-strength grade. Then common blanks can be used for this basic block.

It is thus because of the high-strength design of the basic block no additional sliding plate for the tongue required because the tongue bed is designed as part of the basic block already high strength. In addition, low-lubricity lubricants can be used on this tongue bed, such as sliding surfaces or rollers on the tongue or an additional coating of the tongue bed with a sliding material. However, no additional sliding plate made of steel is required.

A high-strength design is advantageously understood to mean the use of high-strength steel having a hardness in the range from 300 to 460 HB according to Brinell.

On the other hand, standard structural or rail steels can be used for the basic block, in which case the tongue should be formed with a correspondingly reduced hardness. This hardness reduction is preferably at least 10%, in particular at least 20%. However, such a reduction in hardness is also useful in a high-strength formation of the basic block.

Rail steel usually has a hardness in the range of 200 to 260 HB according to Brinell, however, can be achieved by a special aftertreatment even greater hardnesses from 290 HB, which then no longer speaks of natural steel grades.

Constructional steel, on the other hand, can already be delivered to Brinell with hardnesses of less than 200 HB. For the Beischiene structural steels can be used easily because the Beischiene is not used.

For example, the base block could have a hardness of 400 HB, the tongue a hardness of 320-360 HB (but even less) and the stock rail also have a hardness of 400 HB. It is then a high-strength training of the basic block and the whole of the whole tongue device.

If the basic block is not made high-strength, but the wearing components are made from a (structural or) rail steel, an embodiment could look like this: Basic block 260 HB, tongue 210-240 HB, stock rail 260 HB. This embodiment is also useful if the hardness of the rail before and after a switch are not greater and the requirements for wear resistance are not set so high.

Generally, the following should preferably be hardening relations: basic block with a hardness of at least 10-20% more than tongue, the hardness of the stock rail is less than or equal to the hardness of the basic block, the possibly non-exchangeable stock rail is harder than the tongue, because the tongue is the only one Component can be performed easily interchangeable, and the Beischiene has a hardness which is less than or equal to the hardness of the basic block, less than or equal to the hardness of the tongue and / or less than the hardness of the stock rail.

The tongue device according to the invention, in particular for grooved rail turnouts, thus has a stock rail, a Beischiene and a tongue, wherein a tongue bed for the tongue, and is characterized in that a basic block which integrally integrates the tongue bed and a base plate, wherein the Basic block is preferably formed of a steel high-strength grade. This basic block is thus formed in one piece, i. Although he may have cutouts and the like .., However, he does not include, for example, welded or otherwise fortified parts. These other parts are not part of the basic block.

In an advantageous development it is provided that the stock rail and / or the Beischiene are not integrally connected to the basic block. Then the tongue device can be produced particularly easily, and for example the usual steel billets can be used for the stock rail or the Beischiene. Preferably, it is provided that the stock rail and / or Beischiene are formed from a different material to the base block, wherein they are preferably formed of a structural steel or rail steel and the base block is formed in particular of a steel high-strength, which is preferably made by casting , Advantageously, however, one will also use a high-grade steel grade, at least for the parts which are subject to high stress during operation, such as the stock rail. It can be provided that the stock rail is an integral part of the basic block.

In an advantageous development - for which regardless of the design with a basic block that unites the tongue bed and a base plate integrally, wherein the basic block is made of a steel high-strength, independent protection is sought - is provided that the separate stock rail at least partially positively and / or materially connected to the basic block or a substructure, if not the integral basic block is connected, wherein the material bond is preferably present as a weld. As a result, the connection between the base block and jaw or Beischiene is particularly stable and durable.

In an advantageous development, it is provided that the separate stock rail is at least partially positively and / or materially connected to the base block, wherein the material bond is preferably present as a weld. Then this connection is particularly safe and at the same time easy to install.

In an advantageous embodiment, it is provided that the stock rail rests on the base block. As a result, there is a particularly secure connection, because the stock rail does not have to be supported against an unspecified background of the tongue device, which would possibly affect significant leverage forces on the base block.

If the separate stock rail has a projection which engages in an undercut of the base block so that tilting of the stock rail away from the Beischiene is prevented, then there is a special capacity for horizontal forces, as they can always arise during operation when driving over rail vehicles. In a preferred embodiment, the projection extends horizontally and in particular has a length which is less than or equal to a length of a threading aid on the base block. As a result, the positive connection is structurally particularly simple and effective at the same time.

In an advantageous embodiment, it is provided that in addition to the positive connection of the projection and the undercut at least one positive and / or cohesive connection between the stock rail and substructure, preferably two positive and / or cohesive connections between the stock rail and substructure exist, which are designed in particular as a weld. As a result, the anchoring of the stock rail on the base block is particularly safe. In this case, preferably at least two connections should be opposite with respect to the stock rail, whereby forces can be absorbed not only in relation to a tilting in the direction of Beischiene, but also against the direction of Beischiene.

In an advantageous development, it is provided that the base block has a recess on the rear side of the stock rail with respect to the tongue, in which a securing means for fastening the stock rail is arranged. This securing means may be welded or bolted to the base block.

In an advantageous development - for which regardless of the design with a basic block, which integrates the tongue bed and a base plate integrally, wherein the basic block is made of a steel high-strength quality, self-protection is sought - it is envisaged that there is a heater that is arranged between the stock rail and base block or between Beischiene and basic block, wherein the heater is preferably arranged in a recess in the base block, the Beischiene and / or the stock rail. Then the heater is advantageously encapsulated and environmental influences largely removed, the heater remains relatively easy to access in case of maintenance.

In an advantageous development, it is provided that this recess and / or a separate enclosure, preferably a jacket tube for the heater, has a drainage connection. As a result, the heater has a longer shelf life.

In an advantageous development - for which regardless of the embodiment with a basic block, which integrates the tongue bed and a base plate integrally, wherein the basic block is made of a steel high-strength, independent protection is sought - it is envisaged that there is a drainage, the as an opening, preferably formed as a bore, and / or which is arranged in the region in front of the tongue tip in the basic block. As a result, the drainage of the tongue bed is very effective and yet it does not adversely affect the operation of the tongue, since the tongue does not sweep the drainage opening. However, the tongue pushes the water itself into the drainage in its operation, if this does not flow by itself there. there this drainage is particularly connected to the drainage connection of the heater.

Alternatively or additionally, it may be provided that the tongue bed is inclined in the direction of the opening with respect to the horizontal, if the given longitudinal inclination of the track system is too low for natural drainage. This inclination is preferably at least 0.5 ° and in particular at least 1 °.

If the aperture is located less than 3 cm, in particular less than 1 cm from the tip of the tongue, the drainage is particularly effective and the tongue device nevertheless compact.

In an advantageous embodiment, it is provided that the heating consists of a heating element in a cladding tube, wherein the cladding tube does not cross the drainage, but ends at most in the drainage. This dehydration does not disturb the heater and also the cladding can be drained into the drainage.

In an advantageous development, it is provided that in the applied state of the tongue on the stock rail between tongue and stock rail at least partially a cavity. Then, if necessary, stored dirt can store there, so that the proper function of the tongue device is not impaired over a long time, which lengthens maintenance cycles.

In an advantageous development, it is provided that in the area of connecting means between the tongue and an adjusting device, preferably in the region of the passage of the connecting means through the Beischiene, a barrier between tongue bed and control box against water transfer, the barrier in particular as compared to the tongue bed pulled up Edge is formed. This is preferably a raised edge of Beischiene. Then a moisture transfer from the tongue area in the control box is difficult or completely avoided.

In an advantageous development, it is provided that on the base block at least one, the wear resistance-increasing layer is a tongue rest, wherein the Layer preferably comprises at least one material from the group: ceramic material, metallic material, metallic alloys, mixture of ceramic materials and mixtures thereof. This layer, which may be formed, for example, as a coating or as a prefabricated plate, may cover the entire tongue rest or even be present in sections. As a result, the tongue device can be adapted very flexibly to specific needs.

In an advantageous development - for which regardless of the embodiment with a basic block, which integrates the tongue bed and a base plate integrally, wherein the basic block is made of a steel high-strength, independent protection is sought - it is provided that the tongue has an actuating rod which passes through the Beischiene to be preferably outside the Beischiene with a coupling with the slide rod of an adjusting device to be connected. As a result, the tongue device can be designed to be very narrow, since the coupling between tongue and slide rod is not laid in the tongue device itself, but in a control box arranged behind the auxiliary slide. As a result, the drainage of the tongue bed is further promoted, since no depressions and the like. In the basic block for receiving this coupling are required. In addition, the durability of the tongue device improves since the tongue does not have to slide over corresponding edges of such a depression.

In the FIGS. 1 to 9 are similar and identical elements with similar and identical reference numerals. In all FIGS. 1 to 9 each cross-sectional views are shown.

It is in the Fig. 1 to 3 it can be seen that the tongue device 10a, 10b, 10c according to the invention has a base block 12a, 12b, 12c on which a stock rail 14a, 14b is arranged and a connecting rail 16a, 16c. The base block 12a, 12b, 12c integrally includes the lower part 17a, 17b, 17c of the tongue means 10a, 10b, 10c and the tongue bed 18 serving as a support for the tongue 20. *** "

For heating the tongue device 10a, 10b, 10c, a heater 22a, 22b, 22c is provided.

In addition, there is an opening 24 in the base block 12a, 12b, 12c for draining the tongue bed 18. This opening 24 is formed as a bore, the max. 3 cm in front of the tip 25 of the tongue 20 and extends substantially over the entire width of the tongue bed.

The tongue 20 has a tongue base 26, on which an actuating rod 28 is arranged. This control rod 28 is guided through an opening 29 in the Beischiene 16 a, 16 b and is connected in a control box, not shown in the usual manner by means of a coupling with the slide rod of an adjusting device (not shown).

The connection 30, 31 between the tongue base 26 and the control rod 28 is connected to a toothing 30 in the horizontal direction and secured by a screw 31. This allows this connection 30, 31 record very high, horizontal forces acting without being worn.

In addition, no space within the tongue means 10a, 10b, 10c, that is, in the base block 12a, 12b, 12c for the coupling 50 between tongue 20 and slide rod 48th be provided so that the tongue device 10a, 10b, 10c can be constructed narrower overall.

Further details on the construction of the connection between the tongue 20 and the slide bar can be made on the same day under the title: "Tongue device with adjusting device and method for producing a tongue device with adjusting device, in particular for grooved rail turnouts" filed European patent application and the German patent application EN 10 2017 109 634.5 the same applicant, the contents of which are fully incorporated by reference.

In Fig. 1 the peculiarity is that the heater 22a is disposed in a recess 32a of the base block 12a between the stock rail 14a and the base block 12a. As a result, the heater 22a is effectively sealed and protected from the environment.

The stock rail 14a is welded to the base block 12a on both sides 34, whereby a material connection is made. On the other hand, there is a positive connection in that the stock rail 14a has a projection 36a on a projection 37a which engages in a corresponding undercut 38a in the base block 12a, this undercut 38a being arranged in the recess 32a.

When mounting the stock rail 14a, the projection 36a is inserted with the projection 37a from above into the recess 32a and displaced in the direction of the Beischiene 16a until the projection 36a is fully inserted into the undercut 38a, after which the welds 34 are made. The heater 22a is subsequently inserted into the remaining part of the recess 32a from the front side.

By this positive connection 26a, 38a there is clearly a high resistance to tilting of the stock rail 14a to the outside, so away from the Beischiene 16a. As a result, the connection between the base block 12a and the stock rail 14a can also absorb very high forces acting horizontally.

In Fig. 1 the Beischiene 16a is attached to the base block 12a laterally by means of screw 40a.

In Fig. 2 the peculiarity is that the heater 22b is disposed in a recess 32b of the base block 12b between the rail 16b and the base block 12b. As a result, here too the heater 22b is effectively closed and protected from the environment.

The stock rail 14b is in turn welded to the base block 12b on both sides 34, whereby a material bond exists. On the other hand, there is a positive connection in that the stock rail 14b has a projection 36b on a projection 37b, which engages in a corresponding undercut 38b in the base block 12b, this undercut 38b also as in Fig. 1 is arranged in the recess 32b. Here, however, the projection 37b with the projection 36b fills the recess 32 with the undercut 38b substantially completely. Exceptions to this are rounding and the like of projection 37b, projection 36b, recess 32b and / or undercut 38b to 37b approach and projection 36b in recess 32b and undercut 38b can be introduced by a tilted screwing.

As a result of this positive locking, there is again a high resistance to tilting of the stock rail 14b towards the outside, ie away from the insert 16b. As a result, the connection between the base block 12b and the stock rail 14b can also absorb very high forces acting horizontally.

In Fig. 2 the Beischiene 16a is attached to the base block 12b also laterally by means of screw 40b. This attachment 40b is particularly easy to maintain in terms of the heater 22b, since the heater 22b is thus quickly accessible.

In Fig. 3 the peculiarity is that the heater 22c is disposed in a recess 32c of the base block 12c, between the auxiliary rail 16c and the base block 12c. As a result, the heater 22c is also here effectively completed and protected from the environment. However, the Beischiene 16c is not arranged laterally, but inserted into a vestibule 42 of the recess 32c in the base block 12c and welded 44th

The Fig. 4 and 5 Finally serve the purely schematic comparison of the tongue device according to the invention 10d with a conventional tongue device 100, which is exemplified in monoblock construction.

It can be seen that in the case of the tongue device 10d according to the invention there is a base block 12d, on which a stock rail 14d and a connecting rail 16d are arranged. The base block 12d in turn integrally unites the lower part 17d of the tongue device 10d and the tongue bed 18d for the tongue 20d.

The tongue foot 26d is toothed 30d connected to a control rod 28d and secured with a screw 31 which extends through an opening 29d in the Beischiene 16d into a control box 46th In the control box 46, a non-illustrated adjusting device 47 is arranged with a slide rod 48 which is connected via a coupling 50 with the control rod 28d. The screw 31 is detachable at the maximum lying tongue 20 d in the control box 46. For this purpose, the control box 46 has a control box cover 46 ', which is not connected to the end wall 46 "of the control box 46.

It can be seen that no recesses must be provided in the basic block 12d by the adjusting rod 28d and the special type of connection between the adjusting rod 28d and the tongue root 26d. In addition, this compound builds only slightly high, so that it can be inserted into the opening 29d in the Beischiene 16d, so that the tongue device 10d is formed overall very narrow.

In addition, there is the advantage that the drainage bore 24d arranged in front of the tip of the tongue 25d can discharge all water directly under the feeding action of the tongue 20d, if necessary, through the base block 12d.

At the in Fig. 5 shown monobloc tongue device 100 are the jaw rail 102, the lower part 104 of the tongue device 100 with the tongue bed 106 and the Beischiene 108 integrally, that is made in one piece from a block 109.

The tongue 110 is connected here with its tongue base 112 directly to the slide rod 48 via the coupling 50. Since this conventional clutch 50 builds relatively deep, a corresponding recess 114 must be provided in the lower part 104 and the tongue bed 106 of the tongue means and the aperture 116 in the Beischiene 108 must be higher than in Fig. 4 be educated. Overall, the tongue device 100 must also be wider than in Fig. 4 be executed because the coupling 50 from above must be detachable and the tongue with an integral foot up from the tongue device 100 must be removable.

In addition, there is the disadvantage that due to the wide design of the tongue bed 106 very much water can accumulate, which would have to be dissipated by a first to be attached, correspondingly wide drainage 118. Through the recess 114, however, the tongue 110 can not cover this area 114. In addition, there can drain more water in the control box 46, which is disadvantageous.

In Fig. 6 is the peculiarity of the tongue device 10e in that compared to the tongue device 10d after Fig. 4 the base block 12e also integrally includes the stock rail 14e.

In Fig. 7 a sixth preferred embodiment of the tongue device 600 according to the invention is shown, wherein this solution from the tongue device 10a after Fig. 1 among other things by the connection of the control rod 602 to the tongue 604 differs.

More specifically, here the second coupling 606 between control rod 602 and tongue 604 is that the control rod 602 has a head 608 which projects over the outer diameter of the remaining control rod 602. In the tongue 604 a stepped bore 610 is introduced, can be threaded through the control rod 602 and the head 608, so that there is a positive connection in the direction of the Beischiene 612.

The head 608 has a circular basic shape, wherein two opposite sides are formed parallel flattened. Corresponding thereto, the bore 610 is provided with a cover 614, which faces the stock rail 616 and has a contour contoured to the outer contour of the head 608. The cavity 618 behind the cover 614 again has a circular outer contour, so that the head 608 can be freely rotated in the cavity 618.

There could be a detent between the head 608 and cover 614, but this is not necessary because the coupling, not shown between control rod 602 and slide rod automatically prevents rotation of the control rod 602 and thus the head 608 in the bore 610.

By this configuration, a bayonet lock 606 between the actuating rod 602 and tongue 604 is thus generated, which is designed to be particularly low maintenance and safe. In this case, the head 608 of the control rod 602 is sunk in the tongue 604 so that mutual damage between the stock rail 616 and the head 608 is excluded.

Furthermore, it can be seen that the tongue device 600 has a base block 620, on a tongue bed 622 for the tongue 602 consists. The Beischiene 612 is connected by two welds 624 directly to the base block 620, wherein the contours of Beischiene 612 and base block 620 are formed in this connection region so that a heating chamber 626 is formed for the arranged in a sheath 628 heating rod 630. There are therefore both recesses in the basic block 620 and the Beischiene 612, the contours of which are specially adapted for the formation of an angular heating chamber 626.

The heating chamber 626 terminates in a drainage (not shown) located in front of the tongue tip (not shown). As a result, both the heating chamber 626 and the jacket tube 628 can be dehydrated directly into the drainage and no crossing of the heating rod 630 by the drainage, which improves the function. With drainage located in front of the tongue tip, tongue 602 does not have to move over edges and recesses of drainage in tongue bed 622 with its lower edge 632, which significantly reduces the wear of tongue 602 and tongue bed 622.

In addition, the tongue bed 622 is integrally and uninterruptedly disposed under the movable portions of the tongue 602, since all the connection means 602 between tongue 602 and adjusting means (not shown) in the box 636 in the region of the tongue bed 622 do not extend beyond the vertical level of the lower edge 632 of the tongue 602 down. The axis A of the control rod 602 is also arranged so that the actuating rod 602 in the operation of the tongue device 600, the Beischiene 612 and especially its edge 634 does not touch.

The edge 634 of the insert 612 is pulled upwards with respect to the vertical level of the tongue bed 622. As a result, no water can penetrate from the area of the tongue bed 622 into the control box 636, which is not shown in detail.

The stock rail 616 has a horizontal projection 638 located under a horizontal undercut 640 of the base block 620. For placing the projection 638 under the undercut 640 there is a Einfädelhilfe in the form of a tapered recess 642, whose geometry is dimensioned so that the placement can be completed easily. More specifically, for this, the length of the projection 636 is the same, but preferably slightly smaller than the horizontal distance of the lower edge 616a of the stock rail 616 from the edge 642a of the recess 642. The stock rail 616 is in turn secured to the base block 620 by welds 644. Through these three connection points 644, 638, 640 there is a very durable connection, which can also carry high loads, which can also act horizontally.

Finally, the contour of the tongue 602 facing the stock rail 616 is designed such that in the in Fig. 7 shown adjacent state of the tongue 602 on the stock rail 616 between tongue 602 and stock rail 616, a cavity 646 is formed. Through this cavity 646, moisture and dirt located between the tongue 602 and the stock rail 616 can escape, so that the function of the tongue device 600 is not impaired.

Overall, this tongue device 600 thus provides optimal drainage. It is easy to install and maintain, and overall requires very little maintenance, whereby it has a very simple design and can be manufactured inexpensively.

In Fig. 8 a seventh preferred embodiment of the tongue device 700 according to the invention is shown, this solution from the tongue device 600 after Fig. 7 by the connection of the stock rail 702 with the basic block 704.

More specifically, here is a fuse element 706 which is inserted into a gap 708 between the base block 704 and the stock rail 702.
