Description

Die Erfindung betrifft eine Befestigungsvorrichtung für Führungsschienen von Aufzügen, bei welcher die Führungsschienen mittels Schienenklammern gehalten werden, die einen den Schienenflansch beidseitig umfassenden Ausschnitt aufweisen, und die auf an der Schachtwand des Aufzuges angeordneten Befestigungswinkeln befestigt sind.The invention relates to a fastening device for guide rails of elevators, in which the guide rails are held by means of rail clamps, which have a cutout encompassing the rail flange on both sides, and which are fastened to fastening angles arranged on the shaft wall of the elevator.

Bei der Befestigung von Führungsschienen für Aufzüge muss berücksichtigt werden, dass sich bei Temperaturänderungen die Länge der Führungsschienen ändert, und dass mit der Zeit eine Kontraktion des Schachtmauerwerkes eintreten kann. Es müssen daher Vorkehrungen getroffen werden, welche eine Längsverschiebung zwischen Führungsschienen und Schachtmauerwerk gestatten. Es gelangen dabei Befestigungsvorrichtungen zur Anwendung, die eine Verschiebung der Führungsschienen in Längsrichtung gestatten und in Querrichtung verhindern.When fastening guide rails for lifts, it must be taken into account that the length of the guide rails changes when the temperature changes and that the shaft masonry may contract over time. Precautions must therefore be taken to permit longitudinal displacement between the guide rails and the shaft masonry. Fastening devices are used which allow the guide rails to be displaced in the longitudinal direction and prevent it in the transverse direction.

Mit der russischen Patentschrift 494 334 ist eine Befestigungsvorrichtung gemäss Oberbegriff bekannt geworden, die vorstehend aufgestellte Forderungen erfüllen soll. Hierbei ist die Schienenklammer als Stanzteil ausgebildet, das einen stumpfwinklig abgebogenen Schenkel aufweist, in welchem ein nach einer Seite offener, den Schienenflansch beidseitig umfassender Ausschnitt vorgesehen ist. Nach dem Aufschieben der Schienenklammer auf den Schienenflansch, wird diese um eine parallel zum Schienenflansch verlaufende horizontale Achse geschwenkt und mit einem an der Schachtwand angeordneten Befestigungswinkel verschraubt, wobei die Schienenklammer und der Schienenflansch miteinander verklemmt werden.With the Russian patent specification 494 334, a fastening device according to the preamble has become known which is intended to meet the above requirements. Here, the rail clamp is designed as a stamped part which has a leg bent at an obtuse angle, in which a cutout which is open on one side and embraces the rail flange on both sides is provided. After the rail clamp has been pushed onto the rail flange, it is pivoted about a horizontal axis running parallel to the rail flange and screwed to a mounting bracket arranged on the shaft wall, the rail clamp and the rail flange being clamped together.

Eine derartige Schienenklammer weist den Vorteil auf, dass anstelle von zwei Gleitklauen herkömmlicher Konstruktion ein relativ einfaches Stanzteil verwendet werden kann. Es muss jedoch als nachteilig angesehen werden, dass sich bei Winkelungenauigkeiten der Schachtwand, des Befestigungswinkels und der Schienenklammer die Führungsschiene verspannt, und die Verklemmung so gross werden kann, dass die Längsbeweglichkeit der Führungsschiene beeinträchtigt wird Andererseits können sich die Winkelungenauigkeiten derart auswirken, dass die Führungsschiene nicht verklemmt wird und ein unzulässiges Spiel in beiden Querrichtungen auftritt.Such a rail clamp has the advantage that a relatively simple stamped part can be used instead of two sliding claws of conventional construction. However, it must be considered a disadvantage that if the shaft wall, the fastening angle and the rail clamp are inaccurate, the guide rail tensions and the jamming can become so large that the longitudinal mobility of the guide rail is impaired is not jammed and there is an impermissible play in both transverse directions.

Der Erfindung liegt die Aufgabe zugrunde eine Befestigungsvorrichtung gemäss Oberbegriff zu schaffen, die vorstehend beschriebene Nachteile nicht aufweist, und bei welcher die Führungsschienen unabhängig von etwaigen Winkelungenauigkeiten formschlüssig und spielfrei gehalten werden und in Längsrichtung gleiten können.The invention has for its object to provide a fastening device according to the preamble, which does not have the disadvantages described above, and in which the guide rails are held positively and free of play regardless of any angular inaccuracies and can slide in the longitudinal direction.

Diese Aufgabe wird durch die im Patentanspruch gekennzeichnete Erfindung gelöst. Hierbei weist die Schienenklammer einen senkrecht auf dem Schienenflansch stehenden Schenkel auf, in welchem der den Schienenflansch beidseitig umfassende Ausschnitt angeordnet ist, dessen lichte Weite grösser als die Breite des Schienenflansches ist, und der an seinen Seiten keilförmige Hinterschneidungen aufweist. Bei der Montage wird die Schienenklammer auf den Schienenflansch geschoben und um eine senkrecht zum Schienenflansch verlaufende Achse gedreht, bis die Schrägungen der keilförmigen Hinterschneidungen an den Oberkanten des Schienenflansches anschlagen und der spielfreie Formschluss hergestellt ist.This object is achieved by the invention characterized in the claim. Here, the rail clamp has a leg standing perpendicular to the rail flange, in which the cutout comprising the rail flange on both sides is arranged, the clear width of which is greater than the width of the rail flange, and which has wedge-shaped undercuts on its sides. During assembly, the rail clamp is pushed onto the rail flange and rotated about an axis running perpendicular to the rail flange until the bevels of the wedge-shaped undercuts strike the upper edges of the rail flange and the play-free positive connection is established.

Die mit der Erfindung erzielten Vorteile sind darin zu sehen, dass die Schienenklammer auf einfachste Weise montiert werden kann, wobei sich ein verspannungsfreier, das Gleiten der Führungsschiene in Längsrichtung ermöglichender Formschluss problemlos einstellen lässt. Durch die Benutzung des senkrecht auf den Schienenflansch stehenden Schenkels als Schraubenverdrehsicherung wird das Anziehen der Schrauben ohne Gegenhalterung ermöglicht, wobei die Schienenklammer gleichzeitig in die Umklammerungsstellung gedrückt werden kann. Ein weiterer Vorteil ist darin zu sehen, dass durch die annähernd linienförmige Auflage der Führungsschiene auf dem Schenkel der Schienenklammer Winkelungenauigkeiten der Schachtwandbefestigung ausgeglichen werden.The advantages achieved with the invention can be seen in the fact that the rail clamp can be assembled in the simplest way, wherein a tension-free form fit that enables the guide rail to slide in the longitudinal direction can be set without problems. By using the leg perpendicular to the rail flange as a screw Anti-rotation lock enables the screws to be tightened without a counter-holder, whereby the rail clamp can be pressed into the clamping position at the same time. Another advantage can be seen in the fact that the approximately linear support of the guide rail on the leg of the rail clamp compensates for angular inaccuracies in the shaft wall fastening.

Im folgenden wird die Erfindung anhand eines auf der Zeichnung dargestellten Ausführungsbeispieles näher erläutert. Es zeigen:

  • Fig. l eine Ansicht der Befestigungsvorrichtung und
  • Fig. 2 eine Draufsicht der Befestigungsvorrichtung.
The invention is explained in more detail below with reference to an exemplary embodiment shown in the drawing. Show it:
  • Fig. L is a view of the fastening device and
  • Fig. 2 is a plan view of the fastening device.

In den Fig. 1 und 2 sind mit 1 die Wand eines Aufzugsschachtes und mit 2 ein an der Wand 1 angebrachter Befestigungswinkel bezeichnet. Eine Führungsschiene 3 wird von einer Schienenklammer 4 gehalten, die mittels Schrauben 5 mit dem Befestigungswinkel 2 verschraubt ist. Die vorzugsweise als Stanzteil ausgeführte Schienenklammer 4 weist einen senkrecht auf dem Schienenflansch 6 stehenden Schenkel 7 auf, in welchem ein den Schienenflansch 6 beidseitig umfassender Ausschnitt 8 vorgesehen ist. An den Seiten des Ausschnittes 8, dessen lichte Weite grösser als die Breite des Schienenflansches 6 ist, sind keilförmige Hinterschneidungen 9 vorgesehen, deren Schmalseiten 10 kleiner als die Dicke des Schienenflansches 6 sind.1 and 2, 1 denotes the wall of an elevator shaft and 2 denotes a mounting bracket attached to wall 1. A guide rail 3 is held by a rail clamp 4 which is screwed to the mounting bracket 2 by means of screws 5. The rail clamp 4, which is preferably designed as a stamped part, has a leg 7 which is perpendicular to the rail flange 6 and in which a cutout 8 is provided which surrounds the rail flange 6 on both sides. On the sides of the cutout 8, the clear width of which is greater than the width of the rail flange 6, there are wedge-shaped undercuts 9 seen, the narrow sides 10 are smaller than the thickness of the rail flange 6.

Bei der Montage wird die Schienenklammer 4 auf den Schienenflansch 6 geschoben und um eine senkrecht zum Schienenflansch 6 verlaufende Achse gedreht, bis Schrägungen 11 der keilförmigen Hinterschneidungen 9 an den Oberkanten 12 des Schienenflansches 6 anschlagen, womit ein spielfreier Formschluss erreicht ist und der Schenkel 7 eine schräge Lage einnimmt, die beispielsweise unter einem Winkel von 30° zur Querrichtung der Führungsschiene 3 verläuft.During assembly, the rail clamp 4 is pushed onto the rail flange 6 and rotated about an axis running perpendicular to the rail flange 6 until bevels 11 of the wedge-shaped undercuts 9 strike the upper edges 12 of the rail flange 6, which achieves a play-free positive fit and the leg 7 one assumes an inclined position, which extends for example at an angle of 30 ° to the transverse direction of the guide rail 3.

Die Schienenklammer 4 weist einen weiteren, die Biegesteifigkeit verstärkendenen Schenkel 13 auf, der nach der Montage annähernd parallel zur Längsrichtung der Führungsschiene 3 verläuft. Die der Befestigung der Schienenklammer 4 dienenden Schrauben 5 haben vorzugsweise Sechskantköpfe 5.1 und sind derart angeordnet, dass jeweils eine Seite der Sechskantköpfe 5.1 an dem einen Schenkel 7 bzw. an dem weiteren Schenkel 13 anliegt. Dadurch ist es möglich, die Schrauben 5 ohne Gegenhalterung anzuziehen, wobei die Schienenklammer 4 gleichzeitig in die Umklammerungsstellung gedrückt wird.The rail clamp 4 has a further leg 13 which reinforces the bending stiffness and, after assembly, runs approximately parallel to the longitudinal direction of the guide rail 3. The screws 5 used to fasten the rail clamp 4 preferably have hexagon heads 5.1 and are arranged such that one side of the hexagon heads 5.1 abuts one leg 7 or the other leg 13. This makes it possible to tighten the screws 5 without a counter-holder, the rail clamp 4 being pressed into the clasping position at the same time.
