The first working plane (4) is arranged at the bottom end and the second working plane (5) is arranged at the top end of a car supporting frame (8) which is provided for accommodating the elevator car after the erecting work. Above the supporting frame (8), the erecting scaffold continues with the third working plane (6) and ends with the fourth working plane (7). Serving as suspension for the supporting frame (8) are a suspension tube (9), a bottom deflection pulley (10) arranged at the top end of the suspension tube (9), and a top deflection pulley (12) arranged on a shaft girder (11), which are connected via a rope (13), hung in a ratio of 3:1, of lifting rope tackle (14) anchored to the supporting frame (8). The shaft girder (11) carries a speed limiter (17) as well as rope tackle with rope drum (18) which serves to transport material. Here, a hauling rope (20) is diverted at the working point via a jib crane (21) arranged at the top end of the suspension tube (9). The working planes (4; 5; 6; 7), which can be reached via ladders (22) and trapdoors, are protected with railings (24) and hinged barriers. <IMAGE>

Description

Die Erfindung betrifft ein in einem Aufzugsschacht verfahrbares Montagegerüst zur Montage von Schachtausrüstung, bestehend aus einem Hubseilzug für den vertikalen Verhub eines Kabinentragrahmens, an dem am unteren Ende und am oberen Ende Arbeitsebenen angeordnet sind.The invention relates to a movable scaffolding in an elevator shaft for mounting shaft equipment, consisting of a hoist cable for the vertical lifting of a cabin support frame, on which working levels are arranged at the lower end and at the upper end.

Aus der Patentschrift US-A 3 851 736 ist ein Montageverfahren und eine Vorrichtung bekannt, bei dem und bei der die für den höchsten Schachtabschnitt vorgesehenen Führungsschienen im Aufzugsschacht an einem mit Haken versehenen Joch aufgehängt und mittels einer Förderwinde um eine Führungsschienenlänge hochzogen werden. Dann werden an den unteren Enden der aufgehängten Führungsschienen die Führungsschienen für den zweithöchsten Schachtabschnitt aufgehängt und wiederum um eine Führungsschienenlänge hochgezogen. Dieser Vorgang wird so oft wiederholt, bis der Schienenstrang für die Aufzugskabine und das Gegengewicht über die gesamte Schachthöhe reicht. Nachdem das Joch am oberen Schachtende befestigt worden ist, werden die Führungsschienen des untersten Schachtabschnittes mit der Schachtwand verbunden und der Tragrahmen der künftigen Aufzugskabine in den Aufzugsschacht eingesetzt. Die höher gelegenen Führungsschienen werden anschliessend von dem als Arbeitsplattform dienenden und von der Förderwinde angetriebenen Tragrahmen aus mit der Schachtwand verbunden.From the patent US-A 3 851 736 an assembly method and a device is known, in which and in which the guide rails provided for the highest shaft section are suspended in the elevator shaft from a yoke provided with hooks and are pulled up by a guide rail length by means of a conveyor winch. Then the guide rails for the second highest shaft section are suspended from the lower ends of the suspended guide rails and again pulled up by one guide rail length. This process is repeated until the rail track for the elevator car and the counterweight extends over the entire height of the shaft. After the yoke has been attached to the upper end of the shaft, the guide rails of the lowest shaft section are connected to the shaft wall and the support frame of the future elevator car is inserted into the elevator shaft. The higher-lying guide rails are then connected to the shaft wall from the supporting frame, which serves as a working platform and is driven by the conveyor winch.

Ein Nachteil der bekannten Einrichtung liegt darin, dass ein mechanisch aufwendiges, an den Schachtquerschnitt anpassbares Joch notwendig ist, das Mittel zur Auflage auf dem oberen Schachtrand aufweisen muss. Ein weiterer Nachteil der bekannten Einrichtung liegt darin, dass das genaue Ausrichten der Führungsschienen durch den aufgehängten Schienenstrang erschwert wird. Ein weiterer Nachteil liegt darin, dass der als Arbeitsplattform dienende Tragrahmen bereits von den zu befestigenden und auszurichtenden Führungsschienen geführt wird, was wiederum die Montagearbeiten erschwert.A disadvantage of the known device is that a mechanically complex yoke which is adaptable to the shaft cross section is necessary and must have means for resting on the upper edge of the shaft. Another The disadvantage of the known device is that the precise alignment of the guide rails is made more difficult by the suspended rail track. Another disadvantage is that the supporting frame serving as a working platform is already guided by the guide rails to be fastened and aligned, which in turn complicates the assembly work.

Hier will die Erfindung Abhilfe schaffen. Die Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, löst die Aufgabe, die Nachteile des bekannten Montageverfahrens und der bekannten Vorrichtung zu vermeiden und eine Einrichtung zur Montage von Schachtausrüstung anzugeben, mit der insbesondere bei grossen Förderhöhen eine weitgehende Rationalisierung der Montagearbeiten möglich ist.The invention seeks to remedy this. The invention, as characterized in the claims, solves the problem of avoiding the disadvantages of the known assembly method and the known device and of specifying a device for assembling shaft equipment with which extensive rationalization of the assembly work is possible, particularly in the case of large heads.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass gleichzeitig verschiedene Montagearbeiten auf verschiedenen Ebenen ausgeführt werden können, dass mit den Montagearbeiten bereits vor der Fertigstellung des Gebäudes im Rohbau begonnen werden kann, was insbesondere bei Kletterbauweise von Bedeutung ist, dass die Führung des die Arbeitsebenen aufnehmenden Tragrahmens mittels bereits montierter und ausgerichteter Führungsschienen erfolgt und dass dadurch die am Tragrahmen angeordnete und mit dem Geschwindigkeitsbegrenzer zusammenwirkende Fangvorrichtung bereits während den Montagearbeiten der Führungsschienen als Sicherheitseinrichtung verwendet werden kann.The advantages achieved by the invention are essentially to be seen in the fact that different assembly work can be carried out at different levels at the same time, that the assembly work can be started before the building is completed, which is particularly important in the case of climbing construction that the The support frame receiving the working levels is guided by means of already installed and aligned guide rails and that the safety gear arranged on the support frame and interacting with the speed limiter can thus already be used as a safety device during the assembly work of the guide rails.
