Abstract

The mast sections (2) are joined together by connecting screws (8) near the corner post (3) of the mast (1). A traversing platform (4) fitted with a drive mechanism is movably guided along two uprights. A sensor (14) switches on the circuit section's drive mechanism. The mast sections support spaced apart switch strips (13) flush with each other in the abutting part between the mast sections. The distance between each two switch-strips near the sensor is bridged by the loose switch piece clamped against the screw holder of the lower one of the two mast pieces.

Description

Die Erfindung bezieht sich auf einen Bauaufzug mit einem dreiseitigen Mast aus einzelnen Maststücken, die miteinander über Verbindungsschrauben im Bereich der Ecksteher des Mastes verbindbar sind, und mit einer entlang von zwei Eckstehern verschiebbar geführten, mit einem Fahrantrieb ausgerüsteten Fahrbühne, die einen den Fahrantrieb schaltenden Fühler für je ein zwischen zwei Maststücken vorgesehenes Schaltstück aufweist, das ausschließlich durch die Verbindungsschraube der beiden Maststücke im Bereich des der Fahrbühne abgekehrten Eckstehers in einer vom Fühler erfaßbaren Stellung gehalten wird.The invention relates to a construction hoist with a three-sided mast individual mast pieces that are connected to each other via connecting screws in the area the corner posts of the mast are connectable, and with one along two Slidably guided corner platforms equipped with a travel drive, one of the sensors switching the travel drive for one between two Mast pieces provided switching piece, which only by the Connecting screw of the two mast pieces in the area of the driving platform turned corner post is held in a position detectable by the sensor.

Um beim Zusammensetzen des Mastes eines Bauaufzuges aus einzelnen Maststücken das Befahren eines Maststückes zu verhindern, das noch nicht mit dem bereits montierten Mastteil ordnungsgemäß verschraubt wurde, ist es bekannt (AT 401 924 B), an jedem Maststück im Bereich seines oberen Anschlußendes ein um eine horizontale Achse schwenkbares Schaltstück zu lagern, das mit Hilfe einer Verbindungsschraube für die Maststücke in einer hochgeschwenkten Lage gehalten wird, in der es sich außerhalb des Abtastbereiches eines Fühlers befindet, der auf der entlang des Mastes verfahrbaren Fahrbühne angeordnet ist. Da die untere durch das Eigengewicht bedingte Schwenkstellung des Schaltstückes durch den Fühler erfaßt wird, kann beim Ansprechen des Fühlers der Fahrantrieb der Fahrbühne abgeschaltet werden. Das nicht durch die Mastverschraubung in seiner hochgeschwenkten Lage gehaltene Schaltstück zeigt ja eine nicht ordnungsgemäße Montage an. Da bei einem dreiseitigen Mast die Fahrbühne entlang von zwei Eckstehern des Mastes verfahren wird und das Gewicht der Fahrbühne auf den Mast ein Kippmoment ausübt, das eine Zugbelastung des von der Fahrbühne abgekehrten Eckstehers bedingt, reicht es für eine Unfallverhütung aus, die Schaltstücke zwischen den einzelnen Maststücken im Bereich des von der Fahrbühne abgekehrten Eckstehers vorzusehen. Nachteilig bei dieser bekannten Konstruktion ist allerdings, daß die Maststücke im oberen Anschlußbereich mit schwenkbar gelagerten Schaltstücken ausgerüstet werden müssen, was den Konstruktionsaufwand erhöht und das Nachrüsten bestehender Bauaufzüge erschwert. Außerdem besteht die Gefahr, daß aufgrund des rauhen Baustellenbetriebes die Verschwenkbarkeit des Schaltstückes beeinträchtigt wird, das dann nicht mehr gewichtsbedingt in seine Schaltstellung abschwenkt, was dazu führen kann, daß der Fahrantrieb die Fahrbühne in den Bereich eines nicht ordnungsgemäß verschraubten Maststückes oder über das Ende des letzten Maststückes anhebt, wenn nicht ein gesonderter Fühler zum Erkennen des Mastendes vorgesehen wird.To assemble the mast of a construction hoist from individual mast pieces to prevent driving on a mast piece that is not yet with the already assembled mast part was screwed properly, it is known (AT 401 924 B), on each mast section in the area of its upper connection end to store a contact piece that can be swiveled around a horizontal axis Using a connecting screw for the mast pieces in a swiveled up Position is held in which it is outside the sensing range of a sensor is located, which is arranged on the movable platform along the mast is. Since the lower swivel position of the Contact piece is detected by the sensor, when the sensor responds the travel drive of the platform can be switched off. Not through the mast screw connection switching piece held in its swung-up position shows yes incorrect assembly. Because with a three-sided mast Platform is moved along two corner posts of the mast and that Weight of the platform exerts a tilting moment on the mast, which is a tensile load of the corner post facing away from the driving platform, it is sufficient for an accident prevention, the switching pieces between the individual mast pieces to be provided in the area of the corner post facing away from the driving platform. Disadvantageous in this known construction, however, is that the mast pieces in Upper connection area equipped with swivel-mounted contact pieces must be, which increases the design effort and retrofitting existing construction lifts difficult. There is also a risk that due to of the rough construction site operation, the pivotability of the switching element is affected, which is then no longer due to weight in its switching position swings down, which can lead to the fact that the drive drive the platform in the Area of an improperly screwed mast piece or over that The end of the last mast section, if not a separate sensor for Detection of the mast end is provided.

Der Erfindung liegt somit die Aufgabe zugrunde, einen Bauaufzug der eingangs geschilderten Art so auszugestalten, daß mit vergleichsweise einfachen konstruktiven Mitteln eine sichere Überwachung der Mastverschraubung mit einer zuverlässigen Erkennung des Mastendes verbunden werden kann.The invention is therefore based on the object, a construction elevator of the beginning Described kind so that with comparatively simple constructive A safe monitoring of the mast screw connection with a reliable detection of the mast end can be connected.

Die Erfindung löst die gestellte Aufgabe dadurch, daß die Maststücke in an sich bekannter Weise fluchtende, im Stoßbereich zwischen den Maststücken mit Abstand voneinander endende Schaltleisten tragen und daß der Abstand zwischen je zwei der im Bereich des Fühlers angeordneten Schaltleisten durch das lose, mit Hilfe der Verbindungsschraube von unten gegen die Schraubenaufnahme des jeweils unteren der beiden Maststücke geklemmte Schaltstück überbrückbar ist.The invention solves this problem in that the mast pieces in themselves in a known manner, with in the joint area between the mast pieces Bear spacing safety edges and that the distance between two of the switching strips arranged in the area of the sensor loosely, using the connecting screw from below against the screw holder of the lower of the two mast pieces clamped switching piece can be bridged.

Die Erfindung nützt in vorteilhafter Weise den Umstand, daß es zumindest bei einer Gruppe von Bauaufzügen bekannt ist, den Mast zum Anklemmen von Steuerschaltern mit einem Schaltlineal zu versehen, das durch fluchtende Schaltleisten der Maststücke gebildet wird, für eine einfache Überwachung der Mastverschraubung aus, indem der axiale Abstand zwischen den Schaltleisten unmittelbar aufeinandergesetzter Maststücke durch das Schaltstück überbrückt wird, so daß sich bei einer ordnungsgemäßen Mastverschraubung eine über das Schaltlineal durchgehende Abtastleiste für den Fühler der Fahrbühne ergibt. Da das lose Schaltstück mit Hilfe einer der Verbindungsschrauben zwischen den jeweiligen Maststücken von unten gegen die Schraubenaufnahme des jeweils unteren dieser beiden Maststücke geklemmt wird, kann das Schaltstück den Schaltleistenabstand nur bei einem ordnungsgemäßen Anziehen der Verbindungsschraube überbrücken. Außerdem erzwingen die als lose Teile ausgebildeten Schaltstücke ein bei jedem Mastaufbau zu wiederholendes, gesondertes Anklemmen der Schaltstücke, wodurch die angestrebte Sicherheit bei der Überwachung der Mastverschraubung gewährleistet werden kann. In diesem Zusammenhang ist zu berücksichtigen, daß ein lediglich von unten auf die Verbindungsschraube aufgestecktes und nicht durch eine Schraubenmutter gesichertes Schaltstück gewichtsbedingt von der Verbindungsschraube abfällt. Erst mit dem Anziehen der Schraubenmutter und der damit verbundenen Mastverschraubung wird die vom Fühler erfaßbare Überbrückungsstellung des Schaltstückes ermöglicht. Fehlt das Schaltstück, so wird der Fahrantrieb für die Fahrbühne abgeschaltet. In gleicher Weise schaltet der Fühler den Fahrantrieb beim Erreichen des jeweiligen Mastendes ab. Es erübrigt sich daher ein gesonderter Endschalter für diesen Zweck.The invention takes advantage of the fact that it is at least a group of construction hoists is known, the mast for clamping Control switches to be provided with a switching ruler by aligned Safety edges of the mast pieces are formed for easy monitoring of the Mast screwing by the axial distance between the safety edges bridged mast pieces directly bridged by the switching piece is, so that with a proper mast screwing one over the Switching ruler continuous scanning bar for the sensor of the driving platform results. There the loose contact piece using one of the connecting screws between the respective mast pieces from below against the screw holder of each lower of these two mast pieces is clamped, the switching piece can Safety edge distance only if the connecting screw is properly tightened bridge. In addition, the trained as loose parts enforce Switch pieces a separate one to be repeated with each mast structure Clamping the contact pieces, which the desired security in the Monitoring the mast screw connection can be guaranteed. In this context It must be taken into account that one only from below on the connecting screw attached and not secured by a screw nut Switch piece falls off the connecting screw due to weight. First by tightening the screw nut and the associated mast screw connection is the bridging position of the contact piece, which can be detected by the sensor enables. If the contact piece is missing, the drive for the Driving platform switched off. The sensor switches the travel drive in the same way when reaching the respective mast end. There is therefore no need for a separate one Limit switches for this purpose.

Der ausschnittsweise dargestellte Bauaufzug weist einen dreiseitigen Mast 1 auf, der aus einzelnen Maststücken 2 zusammengesetzt ist. Entlang von zwei Eckstehern 3 des Mastes 1 ist eine Fahrbühne 4 verschiebbar geführt, deren Fahrantrieb 5 ein Zahnritzel 6 antreibt, das mit einer Zahnstange 7 entlang eines der Ecksteher 3 kämmt. Die einzelnen Maststücke 2, die entsprechende Abschnitte der Zahnstange 7 tragen, sind in ihrem Stoßbereich miteinander verschraubt. Während im Bereich der die Führung für die Fahrbühne 4 bildenden Ecksteher 3 die Verbindungsschrauben 8 Verbindungsstreben 9 der Ecksteher 3 durchsetzen, greift die Verbindungsschraube 10 im Bereich des von der Fahrbühne 4 abgekehrten Eckstehers 11 in eine Durchgangsbohrung von angeschweißten Schraubenaufnahmen 12 ein, wie dies insbesondere der Fig. 3 entnommen werden kann.The construction elevator shown in sections has a three-sided mast 1 on, which is composed of individual mast pieces 2. Along two Corner posts 3 of the mast 1, a driving platform 4 is slidably guided Travel drive 5 drives a pinion 6, which with a rack 7 along a the corner post 3 combs. The individual mast pieces 2, the corresponding sections the rack 7 carry, are screwed together in their joint area. While in the area of the guide for the driving platform 4 Corner post 3 the connecting screws 8 connecting struts 9 the corner post 3, the connecting screw 10 engages in the area of the Platform 4 turned corner post 11 in a through hole of welded screw receptacles 12, as shown in particular in FIG. 3 can be removed.

Die Maststücke 2 tragen zwischen den Eckstehern 3 miteinander fluchtende Schaltleisten 13, die im Stoßbereich zwischen den Maststücken 2 mit Abstand voneinander enden. Diese sich zu einem Schaltlineal über die Masthöhe ergänzenden Schaltleisten 13 dienen bei bekannten Bauaufzügen zum Anklemmen von Steuerschaltern, die beispielseise Haltepunkte für die Fahrbühne in verschiedenen Höhen festlegen.The mast pieces 2 carry 3 aligned between the corner posts Safety edges 13, which are in the joint area between the mast pieces 2 at a distance end from each other. These complement each other to form a switching ruler over the mast height Switch strips 13 are used in known construction elevators for clamping of control switches, the example stops for the driving platform in different Set heights.

Den Schaltleisten 13 gegenüber befindet sich auf der Fahrbühne 4 ein Fühler 14, der die Schaltleisten 13 z. B. induktiv abtastet. Erfaßt der Fühler 14 das Ende einer Schaltleiste 13, so wird der Fahrantrieb 5 abgeschaltet. Um den Fahrweg der Fahrbühne nicht auf ein Maststück 2 zu beschränken, werden die Abstände zwischen den Schaltleisten 13 durch lose Teile bildende Schaltstücke 15 überbrückt, die über ihren Befestigungsarm 16 von den jeweiligen Verbindungsschrauben 10 im Bereich des Eckstehers 11 in der Überbrückungsstellung gehalten werden. Wie der Fig. 3 entnommen werden kann, wird dabei der Befestigungsarm 16 von unten gegen die Schraubenaufnahme 12 des jeweils unteren der beiden Maststücke 2 festgeklemmt, so daß die Überbrückungsstellung des Schaltstückes 15 nur dann gegeben ist, wenn die Mutter 17 der Verbindungsschraube 10 entsprechend angezogen wird. Bei einem ausreichenden Spiel der Durchtrittsöffnung des Befestigungsarmes 16 für die Verbindungsschraube 10 ist somit die Sicherheit gegeben, daß die Fahrbühne 4 nur bei einer ordnungsgemäßen Mastverschraubung im Bereich des Eckstehers 11 das anschließende Maststück befahren kann. Da eine Fortsetzung der Schaltleisten 13 im Bereich des Mastendes fehlt, dient der Fühler 14 auch für eine Sicherheitsendabschaltung.A sensor is located on the driving platform 4 opposite the switching strips 13 14, the switching strips 13 z. B. inductively scans. Sensor 14 detects this End of a switching strip 13, the travel drive 5 is switched off. To the The path of the platform is not limited to a mast section 2, the Distances between the switching strips 13 by switching pieces forming loose parts 15 bridged by their respective mounting arm 16 from the respective connecting screws 10 in the area of the corner post 11 in the bridging position being held. As can be seen from Fig. 3, the Fastening arm 16 from below against the screw receptacle 12 of each lower of the two mast pieces 2 clamped so that the bridging position of the switching piece 15 is only given when the nut 17 of Connection screw 10 is tightened accordingly. With a sufficient Game of the passage opening of the mounting arm 16 for the connecting screw 10 is thus the certainty that the platform 4 only at a proper mast screw in the area of the corner post 11 that can drive on the subsequent mast section. Because a continuation of the safety edges 13 is missing in the area of the mast end, the sensor 14 also serves for a safety limit switch.
