Description

The invention relates to a method for producing drainage openings in rails with grooves and a rail processing kit for performing such a method.

It is known from the prior art that surface water which arises in track systems, which are created, for example, in paved asphalt, concrete or paved surfaces, is drained in a targeted manner via drainage openings made in the grooves of grooved rails. For this purpose, drainage boxes and drainage channels are fitted between the rails on the track construction site, transversely to the track axis, installed and connected to a collecting line laid in the ground, via which the water is discharged and transferred to the sewage system. After installing the drainage boxes and channels and fastening the surfaces, the rails must be provided with openings in the area below their groove so that the water can drain from the rails into the drainage channels. For this purpose, drainage slots are usually introduced into the rail as a cheap and quick solution using a welding torch. However, the problem with this procedure is that the welding torch has a high and long-lasting heat effect on the rail and the drainage channel attached underneath, which can damage plastic drainage channels in particular.

As an alternative to welding, several holes can be drilled in a row to form the drainage slot, or the opening can be made using an angle grinder. A combination of drilling and angle grinding is also possible and is currently used in plastic drainage channels, which is, however, a time-consuming and cost-intensive procedure.

Starting from this prior art, it is an object of the present invention to provide an improved method for producing drainage openings in grooved rails which can be carried out quickly and inexpensively and which at the same time reduces the effect of heat.

This object is achieved by a method with the features of claim 1.

The further object of providing means with which the method according to the invention can be carried out easily is achieved by the rail processing kit with the features of independent claim 7.

Preferred embodiments of the rail processing kit are set out in the respective subclaims.

1. a) Bestimmen einer Position zumindest einer einzubringenden Entwässerungsöffnung innerhalb eines Rillenbodens der Rille der Schiene über einer Entwässerungsrinne,
2. b) Einlegen einer Führungsschablone in die Rille, dabei Positionieren der Führungsschablone über der vorbestimmten Position der zumindest einen Entwässerungsöffnung,
3. c) Anlegen einer Hitzeschutzvorrichtung zwischen dem Rillenboden und der Entwässerungsrinne unterhalb der vorbestimmten Position der zumindest einen Entwässerungsöffnung,
4. d) mittels eines Plasmaschneiders, der innerhalb der Führungsschablone geführt wird, Einbringen der Entwässerungsöffnung in den Rillenboden der Schiene,
5. e) Entfernen von Plasmaschneider, Führungsschablone und Hitzeschutzvorrichtung.

A first embodiment of the method, which is used to produce drainage openings in grooves in rails which are installed along a track axis with drainage boxes arranged transversely thereto, with a certain number of drainage channels, comprises the following steps:

1. a) determining a position of at least one drainage opening to be introduced within a groove bottom of the groove of the rail above a drainage channel,
2. b) inserting a guide template into the groove, positioning the guide template above the predetermined position of the at least one drainage opening,
3. c) applying a heat protection device between the groove bottom and the drainage channel below the predetermined position of the at least one drainage opening,
4. d) introducing the drainage opening into the groove bottom of the rail by means of a plasma cutter which is guided within the guide template,
5. e) Remove the plasma cutter, guide template and heat protection device.

The rails used here for track construction, on the upper side of which a groove is formed, also known as grooved rails, are standard steel grooved rails according to the prior art. The drainage boxes and drainage channels, also referred to below as channels, are known from the prior art, the channels being provided for direct connection to the rails below their groove and being fitted there.

The terms above / above and below / below refer to the position in relation to the rails laid on a substrate.

The drainage openings can advantageously be produced precisely and quickly by the method according to the invention, the use of a plasma cutter compared to the use of a welding torch resulting in a significantly lower heat input into the groove bottom and the groove underneath as well as a significantly increased cutting speed and thus also compared to the use of drills and angle grinder means time-saving work. By using a heat protection device, which is characterized by a high thermal shielding effect, the heat can spread into the channel further minimized and thus damage caused by heat input can be avoided.

The method according to the invention offers an additional increase in effectiveness for carrying out the plasma cutting work by using a guide template which is produced specifically for the method and is tailored to the planned drainage opening. A suitable material for the guide template is steel, for example. This enables safe, targeted guiding of the plasma cutter while cutting the drainage opening even at an increased cutting speed.

According to a preferred embodiment, steps a) to e) of the method are repeated until a corresponding drainage opening is introduced into the rail above each of the installed drainage channels, i. that is, the method according to the invention is used to produce all the drainage openings provided on the rail, preferably for each rail of the rails.

A further embodiment of the method according to the invention provides that the guide template has at least one opening, the shape of which corresponds to the drain opening of the rail to be introduced or the contour of the drain opening to be introduced. The drainage openings are preferably provided as drainage slots, so that the opening of the guide template has the shape of a narrow, long rectangular frame which corresponds to the contour of a drainage slot or the opening is also a slot. Thus, the cutting pattern for the cutting movement of the plasma cutter is advantageously predetermined by the opening or openings of the guide template and thus the shape and size of the drainage opening are precisely implemented, although other opening shapes can of course also be realized.

Furthermore, it can be provided that the outer shape of the guide template corresponds to the shape of the groove in such a way that the guide template can be arranged displaceably in the groove. For example, a lower part of the guide template protrudes into the notch in the rail that forms the groove, while an upper part lies flat on the groove. This prevents the guide template from slipping or twisting transversely to the groove of the rail and can advantageously be pushed from the position of one drainage opening to the next, so that multiple drainage openings can be introduced in rapid succession.

• d1) Einführen eines Kopfes des Plasmaschneiders durch die Öffnung der Führungsschablone, bis er einen vorbestimmten Abstand zum Rillenboden erreicht,
• d2) Einschneiden der Entwässerungsöffnung in die Schiene mittels Plasmaschneiden, dabei händisch Vorschieben des Plasmaschneiders entlang der Öffnung der Führungsschablone, und
• d3) Herausziehen des Kopfes des Plasmaschneiders aus der Führungsschablone.

In a further preferred embodiment, the method according to the invention comprises the following steps as step d):

• d1) inserting a head of the plasma cutter through the opening of the guide template until it reaches a predetermined distance from the groove bottom,
• d2) cutting the drainage opening into the rail by means of plasma cutting, manually pushing the plasma cutter along the opening of the guide template, and
• d3) pulling the head of the plasma cutter out of the guide template.

The “head of the plasma cutter” is the part of the plasma cutter on the workpiece side from which the plasma cutting beam emerges. Thanks to the guide template, this can only be moved along the intended shape of the drainage opening. With manual plasma cutting, this makes work easier and quicker for the skilled worker, who can concentrate entirely on the speed of the feed.

According to yet another embodiment, the method in step b) can comprise the additional step b1), which provides for the releasably fixing the positioned guide template to the rail, for which purpose easily attachable or releasable fastening means such as clamps or screw clamps can be used, which ensure that the guide template remains in the position determined in step a) during the plasma cutting work.

In a further embodiment, the position of the drainage opening (or more) to be introduced is determined in step a) by first determining in step a1) the location of the groove bottom of the rail above the center of the drainage channel and then marking this location in step a2) , for example via a marked marker, for the purpose of identification for steps b) and possibly c).

According to yet another embodiment, a heat shield, which is preferably made of steel, is used as the heat protection device in step c) in order to shield excess heat that collects below the groove bottom during the plasma cutting work from the drainage channel. A flat heat shield, which is attached between the bottom of the groove and the groove, reflects or absorbs heat as much as possible without being deformed by the application of heat, and insulates the heat impact on the channel. It can be prevented from slipping by releasable fasteners on the rail be secured, or it has a handle that can also be used for fixing.

The invention also relates to a rail processing kit which comprises means for carrying out the method according to the invention, at least one plasma cutter, a guide template and a heat protection device. The kit can be designed differently depending on the specific intended use, in particular the guide template can be designed to fit specific grooved rails and / or have different types of openings that are adapted to the drainage system used and the drainage openings provided for this purpose. With the kit according to the invention, the method for producing drainage openings can advantageously be implemented inexpensively and quickly in various applications.

The guide template preferably has at least one opening, which depicts the shape of the rail drainage opening to be introduced or the contour thereof. For example, it can be a rectangular frame-shaped guide opening with which drainage openings in the form of narrow to wide slots can be created.

A further preferred embodiment of the rail processing kit has a heat shield as the heat protection device, which is preferably made of steel. The heat shield can also have a handle.

The kit can also include several guide templates and / or heat protection devices, so that there is a direct replacement in the event of defects or signs of wear.

In a further embodiment, the rail processing kit further comprises fastening means in order to detachably and without damage attaching the guide template and / or the heat protection device to the rail.

The invention relates to a method for producing drainage openings in grooved rails, which can be carried out in a time-saving manner and with little heat load for the connected drainage channels, and a rail processing kit with the aid of which the method can be carried out.

The entire procedure for producing drainage openings is shown in 9 comprehensible in an overview (dashed arrows for optional steps).

In 1 is an example of a rail 1 , along its length an upwardly open groove 12 has to be seen before executing the method. The grooved bottom 11 the groove 12 is closed. The rail 1 is always with her stand 13 oriented downwards.

The rail 1 can already be installed in a track bed in this state and transversely to the direction of the track, i.e. transversely to the length of the rail 1 , can drainage boxes 6 and drainage channels 7 that the respective rail 1 with the drainage boxes 6 connect, be appropriate. In 8th this state is shown, it being impossible to see in this sectional view that drainage openings 5 in the groove bottom 11 are available (see cross section in 6b) . The drainage boxes 6 can on any position according to the planning documents, ie in particular that on a rail 1 several drainage channels 7 are present, which are arranged at a certain distance from each other and each have an assigned drainage opening 5 in the groove floor above 11 need to drain surface water. 8th represents the usual case that a drainage box 6 between two rails 1 is installed and accordingly with every rail 1 via a drainage channel 7 is connected, the gutter 7 between the top of the stand 13 and the bottom of the groove bottom 11 on the rail 1 is arranged. The entire system can be paved or concreted in order to later be able to absorb the loads caused by traffic.

The connection of the drainage boxes to collecting pipes, which provide a fluidic connection to the local sewage system in order to allow the collected water to drain off, is not shown in the figures.

In the 1 , 2nd , 5 , 6a and 6b are the rails 1 each without the connection to the drainage boxes 6 and in the following the drainage channels necessary for the sewage system 7 shown. The channels can 7 The drainage opening is also fitted and removed after marking its position 5 introduced and the gutters 7 be reinstalled. However, the invention advantageously allows the drainage boxes 6 including the drainage channels 7 are already installed before the method according to the invention is used and on the above the channels 7 horizontal drainage points 5 be generated.

2nd shows the rail 1 at a point in time during the implementation of step b) of the method according to the invention: into the groove 12 the rail 1 is a guide template 4th (following shortened template 4th ) inserted. The template 4th fits perfectly into the groove 12 down to the groove bottom 11 and has an opening towards the top 41 on, which in this embodiment is frame-shaped with a rectangular base. A web in the guide opening is not shown figuratively 41 that the middle part 42 on the template 4th holds. It can be provided according to the invention that the position for the guide template 4th , which is the position of the drainage opening 5 provides, was previously marked by z. B. the middle of the drainage channel 7 was marked, and now serves as a guide. The template 4th can be attached to the rail using fasteners 1 be attached to sliding along the length of the groove 12 to prevent which in 2nd but are not visible.

A plasma cutter 2nd ( 3rd ) and a heat shield 3rd ( 4th ) are considered as further resources. Utensils needed to carry out the procedure. The plasma cutter 2nd has supply lines 23 for power and gas supply, a handpiece 24th as well as a shaft 25th on whose head 21st the plasma cutting beam 22 exit. Together with the template 4th these objects form a rail processing kit according to the invention, which also has means for attaching a template 4th and heat shield 3rd on the rail 1 may include.

In 5 is the rail 1 to be seen at a further point in time during steps c) and d) of the method: the heat shield 3rd is below the intended drainage opening 5 , i.e. under the groove bottom 11 (and above the gutter 7 , not shown). The guide template 4th is still at the previously determined position. The plasma cutter 2nd is with part of its shaft 25th , at least with his head 21st , in the opening 41 the template 4th introduced. The plasma cutter 2nd can therefore only go along the opening in the horizontal direction 41 be moved. Now you can actually create the drainage opening 5 done by the plasma cutter 2nd activated and along the opening 41 the template 4th around the middle part 42 is performed, with a plasma cut in the groove bottom 11 the groove 12 along the contour of the intended drainage opening 5 made and a rectangle from the groove bottom 11 is cut out. Has the plasma cutter 2nd the opening 41 once drained completely, is the drainage opening 5 in the form of a drainage slot 5 generated, the cut rectangle is through the drainage opening 5 removed from the rail and the plasma cutter 2nd can from the template 4th be pulled out. The heat shield too 3rd and the template 4th can be removed or to the position of the next drainage opening to be installed 5 lengthways along the rail 1 be moved.

Not shown figuratively, but optionally possible, is around the guide opening 41 the protrusion surrounding the template,

In 7 is in the rail 1 another embodiment of a guide template 4th inserted a rectangular guide opening 41 without middle part 42 having. Here the plasma cutter can 2nd along the outer edge of the guide opening 41 and an elongated rectangle can also be cut out. The drainage opening thus created has the in the 6a and 6b shown shape.

In a further embodiment, not shown in the figure, the guide template can also have a plurality of openings, which can serve either as a template for common drainage openings for a single channel or for drainage openings for a number of channels installed one behind the other in relation to the rail, so that multiple drainage openings after a single one Positioning the template can be cut out.

A rail 1 after performing the method or after producing at least one drainage opening 5 in the form of a slit 5 in the groove bottom 11 the rail 1 , is in two different sectional views in 6a and 6b shown. In 6a the cross section runs through the rail 1 also through the drainage opening 5 so that it can be seen open to the viewer side. In 6b the cross-section runs before / after the drainage opening 5 , which is therefore closed to the viewer side. As a rule, there will be significantly more than one drainage opening 5 per rail 1 be necessary so that the process steps a) to e) are repeated until over each of the installed (or to be installed) drainage channels 7 a drainage opening 5 incised and a fully functional drainage system is available.
