Description

[0001] Die Erfindung betrifft eine Abbrennstumpfschweissanlage zum Verschweissen von Profilwerkstücken und Rohren, insbesondere von Eisenbahnschienen. The invention relates to a Abbrennstumpfschweissanlage for welding Profilwerkstücken and pipes, especially railroad tracks.

[0002] Beim Erstellen von neuen Geleisen, Austauschen von Schienen oder beim Reparieren von bestehenden Gleisanlagen sind aneinander stossende Enden der Schienen in mobilem und auch stationärem Einsatz zu verschweissen. Hierzu wurden Schweissanlagen der genannten Art entwickelt und bereits in vielen Veröffentlichungen beschrieben, beispielsweise in EP0 597 215. When creating new tracks, replacing rails or when repairing existing track systems abutting ends of the rails are to be welded in mobile and stationary use. For this purpose, welding systems of the type mentioned have been developed and already described in many publications, for example in EP0 597 215.

[0003] Bestehende Anlagen haben den Nachteil, dass die Ausrichtung der Schienen (3) vor dem Schweissen nur beschränkt justiert werden kann. Existing systems have the disadvantage that the orientation of the rails (3) can be adjusted only limited before welding.

[0004] Aufgabe der vorliegenden Erfindung ist es, die Schienen (3) während dem Schweissprozess in Position zu halten und mit grosser Kraft gegeneinander zu pressen. Dabei ist eine zusätzliche Zugkraft aufzubringen, welche benötigt wird um die Schienen (3) auf diejenige Länge zu strecken, die der Länge der Schienen bei Normaltemperatur entspricht und somit ein lückenloses Geleise ermöglicht. Dies ist insbesondere der Fall wenn das zu verschweissende Geleis auf einen bestehenden Gleisabschnitt trifft. Zudem soll jeweils nach dem Schweissprozess der entstandene Schweisswulst abgeschert werden, ohne dass hierzu die Spannvorrichtung (1 + 2) der Schienen entspannt werden muss. Object of the present invention is to keep the rails (3) during the welding process in position and to press against each other with great force. In this case, an additional tensile force is applied, which is required to extend the rails (3) to the length corresponding to the length of the rails at normal temperature and thus allows a gap-free tracks. This is especially the case when the track to be welded meets an existing track section. In addition, after the welding process, the resulting welding bead should be sheared off without the tensioning device (1 + 2) of the rails having to be relaxed.

[0005] Die Aufgabe wurde bei der vorliegenden Erfindung mit den Merkmalen der Patentansprüche gelöst. The object has been achieved in the present invention with the features of the claims.

[0006] Vorteil der vorliegenden Erfindung ist es, dass die zu verschweissenden Schienen (3) vor dem Schweissen mit einer verstellbaren Einrichtung zueinander genau ausgerichtet und damit eine durchgehend gerade Fahrkante der Schienen hergestellt werden kann. Weiter lässt sich der Schweisswulst abscheren, währendem die Schienen noch zusammengepresst werden. Advantage of the present invention is that the welded rails (3) before welding with an adjustable device each other accurately aligned and thus a continuous straight edge of the rails can be made. Furthermore, the welding bead can be sheared off while the rails are still being pressed together.

[0008] Gemäss der Erfindung besteht die Abbrennstumpfschweissanlage aus zwei zueinander verschiebbaren Einspannsystemen (1 + 2) zum Klemmen, Positionieren und Ausrichten der Schienen (3), welche auf einem gemeinsamen Führungssystem (4) angeordnet sind. According to the invention, the Abbrennstumpfschweissanlage consists of two mutually displaceable clamping systems (1 + 2) for clamping, positioning and aligning the rails (3), which are arranged on a common guide system (4).

[0009] Dem Führungssystem, welches parallel zur Schienen-Längsachse angeordnet ist und aus einer oder mehreren Längsführungen (4) besteht. The guide system, which is arranged parallel to the rail longitudinal axis and consists of one or more longitudinal guides (4).

[0010] Einer dritten verschiebbaren Einheit (5) auf dem gleichen Führungssystem (4), welche beispielsweise mit einer Vorrichtung zum Abscheren (6) des Schweisswulstes ausgerüstet ist. A third displaceable unit (5) on the same guide system (4), which is equipped for example with a device for shearing (6) of the welding bead.

[0011] Antriebe (16) zum unabhängigen verschieben der beiden Einspannsysteme (1 + 2) und der dritten Einheit (5) sowie zum Anheben und Spannen der Schienen (3) und Zustellen der Abschermesser (6).

Claims

1. Abbrennstumpfschweissanlage consisting of two mutually displaceable clamping systems (1 + 2) for clamping, positioning and alignment of the rails (3) arranged on a common guide system (4) and various unspecified components characterized characterized in that, the longitudinal guides (4) parallel to Run rail (3) through the entire system with the two clamping systems (1 + 2), at least protrude freely at one end and there are not connected by a crossbar or the like.

2. Abbrennstumpfschweissanlage according to claim 1 with longitudinal drives (7), which are arranged within the longitudinal guides (4) and each transverse pin (8), with which the driving forces to the outside, displaceable units (1, 2 + 5) are transmitted.

3. Abbrennstumpfschweissanlage according to claim 1 equipped with a third unit (5), which are moved independently of the two clamping systems (1 + 2) in the longitudinal direction and can be equipped with Abschermessern (6). This makes it possible to shear the weld bead while the clamped rails (3) continue to be compressed.

4. Abbrennstumpfschweissanlage according to claim 3, wherein the third unit (5) is fixedly connected to the guide units (4) and they join the longitudinal movement. The guide units are mounted for this purpose in both clamping systems (1 + 2) longitudinally displaceable.

5. Abbrennstumpfschweissanlage according to claim 1 equipped with Abschermessern (6) which perform a curved closing and opening movement and thereby not protrude in the open state down from the lower boundary surface of the Abbrennstumpfschweissanlage.

6. Abbrennstumpfschweissanlage according to claim 1 with longitudinal guides (4) which are mounted at the bearing points of the two clamping systems (1 + 2) each with two eccentric bearing bushes (9) arranged inside each other (double eccentric). These double eccentrics have either parallel or crossed axes and allow synchronous and coordinated counter-rotating drive movements to move the clamping systems (1 + 2) parallel to the rail axis horizontally, vertically or alternatively in the angular position to the rail axis. As a result, the alignment of the rails (3) can be adjusted.

7. Abbrennstumpfschweissanlage according to claim 1 with two clamping systems (1 + 2), which are equipped with four eccentric shafts (10), and at the lower end eccentric pin (11). With path measuring systems (12), the position of the four clamping bars (13) of a clamping system is detected and controlled by a position control, the drives (14) of the eccentric shafts. This makes it possible to arbitrarily change the lateral position of the clamping bars (13) and to precisely adjust the lateral orientation of the rails (3) to be welded. After this adjustment, two of these eccentric shafts (10) each by a common drive (16) moves and stretch over the clamping bar (13), the rails (3).

8. Abbrennstumpfschweissanlage according to claim 1 with two clamping systems (1 + 2), which are equipped for clamping the rails (3) with four eccentric shafts (10), which are stored above and below each in eccentric bearing bushes (14). By a targeted and coordinated rotation of these eccentric bearing bushes (14) via a suitable adjustment drive (15), the rail to be clamped (3) on one clamping system (1) can be moved laterally parallel to the rail longitudinal axis. On the second clamping system (2), the angular position of the rail (3) in the horizontal plane by coordinated, opposite rotation of the bearing bushes (14) is set. After these straightening movements, two eccentric shafts (10) each are moved by a drive (16). As a result, the rail (3) is tensioned via a common clamping bar (13), which is arranged at the bottom on the eccentric pin (11) of the eccentric shafts (10).

9. Abbrennstumpfschweissanlage according to claim 1 on both Einspannsystemen (1 + 2) equipped with non-contact optical sensors (17) which can detect an unwanted displacement of the rails (3) in the longitudinal direction during the welding process without electrical contact to the rail (3) manufacture.
