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 11.

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.

In order to move the tongue between the two operating positions, usually located adjacent to the Beischiene boxes, in which adjusting devices are provided. These actuators have a slide rod which is connected to the tongue via a coupling.

For this coupling space must be provided in the tongue device, which is why the corresponding tongue devices build relatively wide.

Object of the present invention is to provide a tongue device with a connection to a positioning device for the tongue, which does not build as wide as previously known solutions. Alternatively or additionally, a simple and efficient drainage should be possible.

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 11. 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 surprising manner very simply and inexpensively that the connection means between the tongue and an adjusting device of the tongue device in the region of the tongue bed not extend beyond the vertical level of the lower edge of the tongue downwards. As a result, the drainage of the tongue bed is promoted, since no depressions and the like. In the tongue bed for the connecting means, for example in the form of a 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 this case, the tongue bearing surface of the tongue bed can be formed in one piece, ie without interruption by recesses for receiving the connecting means or signal-technical components.

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, wherein the connecting means in the region of the tongue bed does not extend beyond the vertical level of the lower edge of the tongue down.

"Connecting means" are generally those means which serve the mechanically coupling connection between tongue and actuator. These can be clutches, slide rods, the adjusting rods described below and the like.

In an advantageous development, it is provided that the connecting means do not rest on the tongue bed, as this prevents damage to the tongue bed or the connecting means.

In an advantageous embodiment, it is provided that the tongue has an actuating rod which extends through the Beischiene, preferably in a control box of the adjusting device, to be preferably outside the Beischiene with a coupling with the slide rod of an adjusting device connectable. 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.

The "control rod" may be round or oval or square in cross section. It may be integrally formed with the tongue, fixed to the tongue or releasably connected to the tongue.

In an advantageous embodiment, it is provided that the adjusting device has a slide rod, which is connected to a first coupling with the control rod. The coupling allows quick replacement in case of maintenance. The first clutch is preferably designed to be movable, wherein in particular a horizontal pivoting about a vertical axis, because this shear forces can be removed during the adjustment process. Preferably, the first clutch is in the operating state of the tongue device in the control box, because thereby the tongue device can be made particularly narrow.

In an advantageous development, it is provided that the tongue has a tongue foot and a tongue bridge, wherein there is a second coupling between tongue foot and / or tongue bridge and control rod. Then the tongue device is particularly easy to maintain. The second clutch is preferably rigid in order to provide a maximum traction.

"Tongue and / or tongue bridge" in this context means that the second coupling between the control rod and the tongue can be connected both to the tongue base, to the tongue bridge and to both.

In an advantageous embodiment, it is provided that the second clutch can be released through an opening in the Beischiene. This opening may consist in the vertical section and / or in the horizontal section of the Beischiene.

In an advantageous embodiment it is provided that the second clutch is formed toothed. As a result, there is a particularly simple, but secure coupling between the tongue and the control rod.

In an advantageous development, it is provided that the second coupling has at least one projection and a corresponding recess in the vertical direction. As a result, the clutch in the direction of action, ie parallel to the extension of the control rod, relieved.

In an advantageous development, it is provided that the second clutch has a positive connection. This also relieves the second clutch in the effective direction, that is, parallel to the extent of the control rod.

In an advantageous development, it is provided that the second clutch has a screw connection. Through this screw is a particularly secure coupling, which can be very small dimensioned in connection with a positive connection and / or training with projection and corresponding return, because you do not have to secure high loads.

The screw connection can extend both in relation to the tongue and parallel to the vertical extent of the tongue as well as transversely thereto. In the latter case, the screw is preferably arranged away from the adjusting device on the tongue, wherein the control rod or a corresponding coupling piece of the control rod is inserted in particular through the tongue and on the side of the actuator side of the tongue is a positive connection, for example in the form of at least one shoulder , wherein the shoulder is formed in particular circumferential.

In an advantageous embodiment, it is provided that the adjusting rod is inserted into the tongue, preferably inserted through it, because it can be structurally particularly simple and easy to maintain coupling with the tongue. If the control rod has a head which is recessed in the tongue, wherein in particular a bayonet lock exists between the head and the tongue, then the tongue device is particularly low-maintenance and installation-friendly.

In an advantageous development, it is provided that the tongue has a tongue base and a tongue bar and the actuating rod is fixedly connected to the tongue base and / or the tongue bar, wherein it is preferably provided that the female table has an upwardly open opening, which in particular is designed to be closable is. Then the connection of the tongue is particularly durable, since there is no releasable connection between the tongue and the control rod. In this context, "solid" means insoluble, for example, welded or integrally connected. So there is no releasable coupling.

In an advantageous embodiment, it is provided that in an advantageous development, it is provided that the adjusting device has a control box with an end wall, wherein the end wall also has an opening which is formed closable, wherein it is preferably provided that the closure of the Beischiene and the Closure of the end wall are designed as a common closure. Then the tongue can be mounted and maintained particularly easily and conveniently.

In an advantageous development it is provided that the tongue device has a drainage in the region of the tongue bed, which is preferably designed as an opening, in particular as a bore. This area is burdened, for example, when it rains with a high volume of water, so that a drainage of this area extends the shelf life and secures the operation of the tongue device especially in the cold.

If the drainage is located in the area in front of the tip of the tongue, 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.

In an advantageous embodiment, it is provided that a heating device with 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, in the region of the connecting means, preferably in the region of the passage of the connecting means through the Beischiene, a barrier between tongue bed and control box against water, wherein the barrier is formed in particular as compared to the tongue bed raised edge. 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 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.

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 °.

Further details on the construction of the tongue device according to the invention can be found in the European patent application filed on the same day under the title: "Tongue device and method for producing a tongue device" 10 2017 109 636.1 the same applicant, the contents of which are fully incorporated by reference.

A sixth embodiment of the tongue device according to the invention.

In the FIGS. 1 to 7 are similar and identical elements with similar and identical reference numerals. In all FIGS. 1 to 7 each cross-sectional views are shown.

It is in the Fig. 1 to recognize that the tongue device 10 according to the prior art, a lower part 12 has, which may be formed, for example, elevated (not shown) on which a stock rail 14 and a Beischiene 16 are attached.

At the lower part 12, a tongue bed 18 is formed, on which a tongue 20 is slidably disposed. To reduce the friction, separate sliding layers or sheets, or rollers may be provided on the tongue 20 (not shown).

The tongue 20 has a tongue base 22, which is connected via a coupling 24, which has a bolt 26, with a slide rod 28 of a not fully shown adjusting device 30. This adjusting device 30 is arranged in a control box 32, which then extends to the Beischiene 16.

Shown are of the control box 32 of the box lid 32 'and the end wall 32 "of the box 32. Usually, the box lid 32' on two longitudinal walls, not shown, of the box 32 and is bolted there and there is no connection between the box lid 32 'and end wall 32nd "but there is usually a gap 33 between them. For maintenance of the actuator 30, the box lid 32 'is then removed.

The Beischiene 16 and the control box 32 each have an opening 34, 36, through which the slide rod 28 runs.

In addition, the tongue bed 18 is provided with a recess 38 which gives space for the coupling 24 with the bolt 26. However, this recess 38 has a negative effect on the durability of the tongue 20, since this tongue 20 always when adjusting with the actuator 30 via the edges 40 of the recess 38 is moved, resulting in increased wear. In addition, the tongue is not supported in the region of the recess 38.

For dewatering, one could equip this tongue device 10 according to the prior art with a drainage in the form of an opening 42 in the lower part 12. However, this would have the disadvantage that this forms further edges 44 over which the tongue 20 would be guided, which increases the wear even more. In addition, due to the recess 38 not all water is discharged by the tongue movement itself.

In Fig. 2 a first preferred embodiment of the tongue device 100 according to the invention is shown.

It can be seen that the tongue device 100 according to the invention has a lower part 12a in the form of a basic block, on which the stock rail 14 and an auxiliary rail 16a are arranged. Further details on the design of the basic block 12a can be found in the European patent application filed on the same day under the title: "Tongue device and method for producing a tongue device" 10 2017 109 636.1 the same applicant, the contents of which are fully incorporated by reference.

Instead of a basic block, however, other configurations of the lower part 12 a can also be used, that is, for example, also modified.

The tongue bed 18a is continuous and without recesses, as in Fig. 1 formed so that it supports the tongue throughout and without edge effect.

The tongue 20a has a tongue root 22a which is formed with a vertically upstanding projection 102.

At the tongue base 22a, a coupling 106 for connecting the tongue root 22a with an adjusting rod 108 is fastened with a screw connection 104. The part of the coupling 106 belonging to the adjusting rod 108 has a recess 110 corresponding to the projection. This coupling 106 is rigid.

The control rod 108 is connected to the coupling 24 and the bolt 26 with the slide rod 28a of the actuator 30a, which in turn is located in a voltage applied to the Beischiene 16 control box 32a. This clutch 24 is thus held movable and although in the horizontal direction pivotable about the pin 26th

Both the Beischiene 16 and the control box 32a are in turn provided with openings 34a, 36a for the actuator 30, wherein the opening 36a in the end wall 32a "of the box 32a and the box lid 32a'wiederum not with the end wall 32a" is connected. In this embodiment of the invention, however, a significantly lower vertical height of these openings is obviously necessary because the coupling 106 is much flatter. As a result, less dirt from the tongue bed 18a can be entered into the control box 32a.

The coupling 106 between tongue 20 and control rod 108 also has many other advantages.

For one thing, it does not build deeper in relation to the vertically lowest level of the tongue 20, which is at the level of the tongue bed 18a. As a result, no recesses 38 in the tongue bed 18a are necessary and the tongue 20a is always supported by the tongue bed 18a. Since there are no corresponding edges due to the missing recess 38, the wear is much lower.

On the other hand, a drainage in the form of an opening 42a is arranged approximately 1 cm apart from the tongue tip 112. Accordingly, this opening 42a is likewise not run over by the tongue 20a during the adjustment, so that no wear of the tongue 20a is effected by the edges 44a of this opening 42a.

Further details on the design of the drainage can be obtained from the same applicant's patent application filed on the same day under the title: "Tongue Device and Method for Producing a Tongue Device", to the content of which reference is made in full.

Due to the non-deep coupling 106, the entire tongue bed 18a can be free of recesses 38, so that water can flow freely into the drainage 42a and possibly the drainage is still promoted by the adjustment of the tongue 20a, which pushes the water into the drainage 42a ,

Furthermore, by virtue of the vertical toothing of the coupling 106 with the projection 102 and the corresponding recess 110, there is a positive connection in the direction of the longitudinal extension of the adjusting rod 108, ie in the direction of action of the adjusting device 30 with respect to the tongue 22a. This form fit carries the entire load during the adjustment process, so that the screw 104 serves only for safety and must be dimensioned only very small.

Finally, the lateral extent of the coupling 106 is substantially lower than that of the coupling 24, so that the tongue device 100, so the lateral distance between the stock rail 14 and Beischiene 16a can be kept much lower.

The coupling 106 is formed here with a toothing, but there are also solutions with multiple gears possible. In addition, the projection 102 may also be disposed on the adjusting rod 108 and the recess 110 on the tongue base 22a.

In addition, other teeth, so not with vertically extending active surfaces 114, 116, but for example with oblique and / or curved running Impact surfaces possible, as well as in the contact surface 118 between the tongue 20a and the control rod 108 is the case.

In Fig. 3 a second preferred embodiment of the tongue device 200 according to the invention is shown.

It can be seen that this tongue device 200 moves from the tongue device 100 to Fig. 2 only distinguished by the formation of the coupling 106b between the tongue 20b and the adjusting rod 108b.

More precisely, the tongue 20b displaceably arranged on the tongue bed 18b here has a very short tongue foot 22b, and the adjusting rod 108b has a coupling piece 202 which also has a very short side construction. Between the tongue 20b and the coupling piece 202 in turn there is an obliquely extending active surface 118b and in addition a vertically extending active surface 204th

Since in this case there is no toothing, that is to say no positive locking in the direction of action of the adjusting device 30b with respect to the tongue 20b, the corresponding screw connection 104b must carry considerably more loads during the adjusting procedure, which is why it must be correspondingly more strongly dimensioned.

The advantages of this embodiment are that the coupling 106b has an even smaller lateral extent than the coupling 106 after Fig. 2 so that the tongue device 200 can be made even narrower.

On the other hand, the coupling 106b is structurally simpler, so that it can be made simpler and less expensive.

In the preferred embodiments, the control rod 108, 108b was always connected to the tongue 20a, 20b via a releasable coupling 106, 106b. However, it is also possible to connect the control rod inextricably with the tongue, for example by welding. Again, however, can be provided to relieve this connection a positive connection.

In addition, the control rod could also be integrally connected to the tongue. A corresponding embodiment is in Fig. 4 with the third preferred embodiment of the tongue device 300 according to the invention.

It can be seen that the tongue means 300 only according to the second preferred embodiment Fig. 3 distinguishes that the tongue base 22c is integrally connected to the control rod 302, which allows the connection to the actuator 30c. However, instead of an integral connection, it is also possible for there to be a fixed arrangement, for example by welding.

In order to allow the insertion of the control rod 302 in the apertures 304, 306 of Beischiene 16c and control box 32c, the Beischiene 16c and the end wall 32c "of the box 32c vertical incisions on with corresponding closure pieces 308, 310 of Beischiene 16c and Stellkastenstirnwand 32c "are closed, provided. The anchoring of the closure pieces 308, 310 in the insert 16c and the box lid 312 can take place, for example, by means of lateral pins or the like in the insert 16c and the end wall 32c "The box lid 32c 'is in turn not connected to the end wall 32c".

This solution is associated with two additional parts in the form of the inserts 308, 310, in addition, thereby the storage of corresponding tongues 20c is complicated.

It could therefore alternatively be provided a uniform closure piece 312, wherein the closure pieces 308, 301 fixedly connected to each other, for example, are welded. As a result, only one element, namely the common closure piece 312 consisting of the closure pieces 308, 310, has to be removed from the insert 16c and the end wall 32c ", which considerably simplifies the handling and, moreover, the anchoring could be simplified since now, for example, only one anchoring of the closure piece 312 must take place in the Beischiene 16c.

Alternatively, after the in Fig. 5 shown fourth preferred embodiment of the tongue device 400 according to the invention also be provided that in the field of Openings 304, 402 of Beischiene 16c and 32d control box on the end wall 32d "of the box 32d is omitted, ie the end wall 32d" of the box 32d is missing in the region of the opening 402 and the Durchbrechnung 402 is pulled up to the box lid 32d '. Thus, the box lid 32d 'projects with its portion 404 in the region of the aperture 302 corresponding to the missing end wall 32d "in the direction of the Beischiene 16c.

Thus, there is only a single closure piece 308 of the Beischiene 16 c, which must be removed for insertion or removal of the control rod 302, which in turn simplifies handling.

Instead of a protrusion 404 of the box lid 32d ', however, it may also be provided that a section (not shown) covering the end wall 32d is arranged, for example welded, on the closure piece 308 of the insert 16c Then the box lid 32d' can advantageously have no projecting portion 404 be formed.

Alternatively, it is also possible to completely dispense with the end wall 32d "of the control box 32d (not shown), with the control box cover 32d 'then extending over its entire length to the auxiliary rail 16c.

In addition, in all examples 100, 200, 300, 400 it could also be provided that the respective box lid 32a ', 32b', 32c ', 32d' overlaps over the corresponding end wall 32a ", 32b", 32c ", 32d" ( Not shown). This would avoid gaps 33 between the end wall 32a ", 32b", 32c ", 32d" and the service box lid 32a ', 32b', 32c ', 32d'.

In Fig. 6 a fifth preferred embodiment of the tongue device 500 according to the invention is shown, wherein this solution from the tongue device 100 according to Fig. 2 distinguished by the connection of the control rod 502 to the tongue 504, which in turn passes through the Beischiene 505.

More specifically, here the second coupling 506 is that the control rod 502 has a thread 508 and passed through a hole 510 in the tongue base 512, tongue bar 514 of the tongue 504 and 518 screwed away from a non-illustrated adjusting device 516. At the same time, the control rod has a peripheral shoulder 520, which is positively supported against the tongue 504, whereby the tongue 504 can be adjusted securely and permanently by means of the adjusting device 516. Alternatively, not the adjusting rod 502 itself, but a corresponding coupling piece of the adjusting rod 502 could be inserted through the tongue 504 (not shown).

In addition, it can be seen that the control rod 502 is arranged so that it does not drag on the tongue bed 522, whereby the tongue device 500 is particularly low maintenance.

In addition, it can be seen that the jaw rail 524 has an opening 526 into which the screw 518 can dip with the end of the thread 508 of the control rod 502. In addition, the screw through this opening 526 by means of a suitable tool is solvable. However, such an opening 526 may also be dispensed with, or it may be converted into a mere recess for the tongue 504, if sufficient clearance between the tongue 504 and the stock rail 524 and / or the screw connection is detachable from above.

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 500 after Fig. 5 distinguished by the connection of the control rod 602 to the tongue 604.

More specifically, here the second coupling 606 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 to this, the bore 610 is provided with a Cover provided 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.

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, the geometry of which is dimensioned so that the placement can be completed easily. The stock rail 616 is in turn secured to the base block 620 with welds 644.

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.

From the above description it has become clear that the tongue device 100, 200, 300, 400, 500, 600 according to the invention with a connection to an adjusting device 30a, 30b, 30c for the tongue 20a, 20b, 20c, 504, 602 does not build so wide , as previously known solutions. In addition, it is much more durable because it is less exposed to wear and allows easy and efficient drainage.

Unless otherwise indicated, all features of the present invention may be freely combined with each other. The features described in the description of the figures can, unless stated otherwise, be freely combined with the other features as features of the invention. Objective features of the device can also be reworded into process features as part of the method, and method features in the context of the device can be re-formulated into device features.
