Abstract

A working platform (1) is suspended by hoist and guide ropes (7) from a support fixed to the structure at the top, and is driven vertically up and down by a motor. One or more holding jaws (2) are mounted on the platform, having a clamping mechanism acting between left and right-hand arms. Where the structure (4) is of constant or varying circular cross-section, the clamping mechanism can be designed to exert a constant pressure against it. The jaw arms can be equipped with steering rollers, and a rotor-blade cleaning machine can be mounted on the platform.

Description

Die Erfindung betrifft eine Befahranlage nach dem Oberbegriff des Anspruchs 1.The invention relates to an access system according to the preamble of claim 1.

Derartige Befahranlagen werden vor allem an Bauwerken mit gleichbleibenden bzw. veränderlichem kreisförmigen Grundriß eingesetzt.Such access systems are mainly used on structures with constant or variable circular floor plan used.

Diesem entsprechen zum Beispiel Türme von Windkraftanlagen und Schornsteine, die als Kreiszylinder oder Kegelstumpf, sowie Bauwerke, die als Rotationsparaboloid oder Rotationshyperboloid ausgeführt sind. Hier werden Betonsanierungs- oder Korrosions­ schutzarbeiten an Stahlkonstruktionen durchgeführt.For example, this corresponds to towers of wind turbines and chimneys, which as Circular cylinder or truncated cone, as well as structures that serve as a paraboloid of revolution or Rotational hyperboloid are executed. Here are concrete renovation or corrosion protective work performed on steel structures.

Die bekannten Befahranlagen weisen eine Arbeitsbühne auf, die mit speziellen Winden an Fahr- und Führungsseilen auf und ab bewegt werden kann.The known lift systems have a working platform with special winches Driving and guide ropes can be moved up and down.

Zur sicheren Fixierung der Arbeitsbühne werden an den bisher bekannten Befahranlagen Spannseile, Magneten oder spezielle Strömungsmaschinen verwendet.In order to securely fix the work platform on the previously known access systems Tension cables, magnets or special fluid machines are used.

Durch diese Maßnahmen sollen Pendelbewegungen in radialer und tangentialer Richtung verhindert werden.These measures are intended to make pendulum movements in the radial and tangential directions be prevented.

Die DE 38 22 424 A1 beschreibt eine Befahranlage, die mittels auf Auslegern montierten Magnetplatten die Arbeitsbühne am Bauwerk festhalten und pendelnde Bewegungen verhindern soll. Bei dieser Lösung entfallen die Spannseile, welche mitunter bei der entsprechenden Einsatzhöhe der Arbeitsbühne ein hohes Eigengewicht und eine große Windangriffsfläche darstellen können.DE 38 22 424 A1 describes an access system which is mounted on brackets Magnetic plates hold the work platform to the structure and oscillating movements should prevent. With this solution, the tension ropes, which are sometimes used in the appropriate working height of the work platform a high weight and a large Can represent wind attack surface.

Die Konstruktion der Befahranlage ist jedoch nicht in der Lage, die Arbeitsbühne sicher vor dem Abheben vom Bauwerk zu schützen.However, the construction of the access system is unable to secure the work platform to protect against lifting off the structure.

Die Magnetplatten (b), sh. Fig. 1, an den Auslegern (c) haben die Aufgabe, durch das erzeugte Feld die Arbeitsbühne (d) sicher am Bauwerk (a) zu halten und dabei horizontale bzw. vertikale Bewegungen der Arbeitsbühne (d) zu ermöglichen. Die Stärke des Magnetfeldes richtet sich nach der Summe der auf die Arbeitsbühne (d) wirkenden Kräfte und Momente bis zu dem Punkt, bei dem keine der gewollten Bewegungen der Arbeitsbühne (d) mehr möglich sind.The magnetic disks (b), sh. Fig. 1, on the cantilevers (c) have the task of holding the work platform (d) securely on the structure (a) by the generated field and thereby enabling horizontal or vertical movements of the work platform (d). The strength of the magnetic field depends on the sum of the forces and moments acting on the work platform (d) to the point at which none of the desired movements of the work platform (d) are possible.

Dieser Zustand ist jedoch unerwünscht.However, this condition is undesirable.

Für Arbeiten an Rotoren von Windkraftanlagen ist es unerläßlich, relativ große Abstände zwischen dem Turm und dem jeweiligen Rotorblatt zu überwinden. So kommt es durch das Eigengewicht der Konstruktion, der Zusatzgeräte und des Personals zur Bildung eines vertikal wirkenden Drehmomentes. Der Durchmesser des Turmes (a) entspricht ungefähr der Breite der Arbeitsbühne (d). Das bedeutet, daß die Ausleger (c) seitlich des Turmes (a) angelenkt werden. Durch das genannte Moment kippt die Arbeitsbühne (d) über ihre untersten Laufräder nach unten ab, da die Magnetausleger mit den Kugelrollen und ihrer drehbaren Lagerung trotz der von ihr aufgebrachten Haftkraft an den Turm (a) eine Bewegung nach oben ermöglichen.When working on wind turbine rotors, it is essential to have relatively large distances to overcome between the tower and the respective rotor blade. So it comes through that Dead weight of the construction, the additional devices and the personnel to form a vertically acting torque. The diameter of the tower (a) corresponds approximately the width of the work platform (d). This means that the arms (c) to the side of the tower (a) be articulated. Due to the aforementioned moment, the working platform (d) tilts over hers Bottom wheels down as the magnetic boom with the ball rollers and their  rotatable bearing in spite of the adhesive force applied to the tower (a) Allow upward movement.

Der Nachteil der in der DE 38 22 424 A1 beschriebenen Konstruktion besteht darin, daß die Arbeitsbühne keine größeren, vertikal wirkenden Drehmomente aufnehmen kann, ohne das die Arbeitsbühne von der Bauwerksoberfläche abhebt bzw. noch vertikal bewegt werden kann.The disadvantage of the construction described in DE 38 22 424 A1 is that the work platform cannot absorb larger, vertically acting torques without that lifts the work platform from the surface of the building or moves it vertically can be.

Sollen die eben genannten Momente kompensiert werden, muß das von den Magneten erzeugte Feld so stark sein, daß keine Bewegung der Arbeitsbühne mehr möglich ist. Folglich ist die Haftung der Arbeitsbühne mittels nicht feststellbaren Magnetauslegern an Bauwerken geringeren Umfanges ungeeignet, eine hohe Betriebssicherheit bei Arbeitsbühnen mit in radialer Richtung des Bauwerkes langen Arbeitsflächen und der Möglichkeit der gleichzeitigen vertikalen Bewegung zu gewährleisten.If the moments just mentioned are to be compensated, this must be done by the magnets generated field so strong that no movement of the work platform is possible. As a result, the liability of the work platform by means of magnetic brackets that cannot be determined is on Smaller structures unsuitable, a high level of operational reliability Working platforms with long working surfaces in the radial direction of the structure and Possibility to ensure simultaneous vertical movement.

Der Erfindung liegt die Aufgabe zugrunde, die Arbeitsbühne einer derartigen Befahranlage so zu gestalten, daß die bekannten Spannseile entfallen, die Arbeitsbühne aber dennoch an gekrümmten Flächen zuverlässig gegen das Bauwerk gedrückt und damit ein Pendeln und Ausschwingen verhindert wird.The invention has for its object the working platform of such an access system to be designed in such a way that the well-known tensioning ropes are omitted, but the work platform is still on curved surfaces reliably pressed against the structure and thus a pendulum and Swinging is prevented.

Erfindungsgemäß wird diese Aufgabe durch den Inhalt des Anspruches 1 gelöst. Die zangenartigen Seitenarme halten die Arbeitsbühne sicher an Bauwerkflächen, die aus Stahl, Stahlbeton oder anderen festen Stoffen bestehen können, fest und ermöglichen eine vertikale Bewegung der Arbeitsbühne an der Bauwerkfläche. Trotz des Wegfalls der sonst üblichen Spannseile kommt es zu keinen Pendel- bzw. Ausschwingerscheinungen. Durch die demzufolge in Leichtbauweise gefertigte Arbeitsbühne fallen die turmspezifischen Anhängevorrichtungen des Trageseils leichter aus.According to the invention, this object is achieved by the content of claim 1. The pincer-like side arms hold the work platform securely on building surfaces Steel, reinforced concrete or other solid materials can consist of solid and enable one vertical movement of the work platform on the building surface. Despite the elimination of the otherwise usual tensioning ropes there are no pendulum or swinging phenomena. Due to the lightweight construction, the working platform falls tower-specific attachments of the suspension cable easier.

Mit Hilfe spezieller Spannvorrichtungen kann der Anpreßdruck der Laufräder an den Seitenarmen und somit auch der Arbeitsbühne an die Bauwerkoberfläche je nach den herrschenden Einsatzbedingungen variiert und dann konstant gehalten werden. Die Spannvorrichtungen können am Fuß, wie es in der Fig. 4 dargestellt ist, oder am Kopf der Seitenarme befestigt werden.With the help of special clamping devices, the contact pressure of the impellers on the side arms and thus also the work platform on the building surface can be varied depending on the prevailing conditions of use and then kept constant. The clamping devices can be attached to the foot, as shown in FIG. 4, or to the head of the side arms.

Somit wird die Arbeitsbühne selbst bei variablem Bauwerkdurchmesser und gleichzeitiger vertikaler Bewegung mit einer konstanten Kraft an die Bauwerkoberfläche gepreßt. Der entscheidende Vorteil der Erfindung besteht darin, daß über die einstellbare und konstante Druck- bzw. Zugkraft, welche auf die Seitenarme wirkt, ein vertikal auf die Arbeitsbühne wirkendes Drehmoment kompensiert und somit ein Abheben der Arbeitsbühne von der Bauwerkoberfläche verhindert werden kann.This makes the work platform even with a variable structure diameter and more simultaneous vertical movement pressed against the surface of the building with a constant force. The decisive advantage of the invention is that the adjustable and constant pressure or tensile force, which acts on the side arms, a vertical on the Working platform compensated torque and thus a lifting of the Working platform from the building surface can be prevented.

Es ist hiermit möglich, Arbeitsbühnen so zu gestalten, daß sie Arbeiten in einem weiteren Abstand vom Bauwerk ermöglichen und gleichzeitig sicher an die Oberfläche eines solchen Bauwerkes gedrückt werden. Bei Bedarf kann ein Neigungsausgleich vorgenommen werden. An einer anderen vorteilhaften Ausführungsform der Arbeitsbühne ist ein für Rotorblätter speziell zugeschnittenes Reinigungsgerät montiert.It is hereby possible to design work platforms so that they work in another Allow distance from the structure and at the same time safely to the surface of such Structure are pressed. If necessary, a slope compensation can be made become. In another advantageous embodiment of the work platform is a for Rotor blades specially tailored cleaning device installed.
