EP2325394B2 - Method and device for applying a liquid to a rope - Google Patents

Description

The subject of the present invention is a method for applying a liquid to a rope and an arrangement consisting of a rope and a device for applying a liquid to a rope. The method and arrangement can be used in particular for examining, cleaning, repairing and applying coatings and for marking load-bearing ropes, such as those used on bridges or similar structures.

Ropes or rods that are installed stationary in technical structures, such as rope or suspension bridges, to transmit tensile forces must be inspected regularly in order to prevent third parties and the structures themselves from being endangered by unexpected breaks in the ropes or rods. To do this, it is often necessary to apply liquid testing systems or indicator liquids to the ropes in order to detect damage or corrosion. In addition, the ropes must be cleaned, coated and marked and their coatings repaired. Until now, this work on ropes or rods has taken place using manned inspection devices and aerial work platforms. Unmanned inspection devices are also known, for example from DE 203 11 395 U1 as well as the unpublished German patent application DE 10 2008 049 942.0 . Furthermore, from the US 2,858,555 a device for cleaning or painting ropes is known.

Since large lengths of rope often have to be inspected and processed during the work mentioned on the ropes or rods, especially on suspension or rope bridges - rope lengths of several hundred meters in length are common - the following invention is based on the task of specifying a method and a device, with which the disadvantages known from the prior art can be at least partially overcome, even when working on ropes of great length, and in particular an unmanned application of liquid to a rope can be carried out. This task is solved by a method and an arrangement with the features of the independent claims.

The respective dependent claims are directed to advantageous further developments.

The method according to the invention for applying a liquid to a rope, in which a rope is driven with a device which comprises at least three rollers which are non-positively connected to the rope, at least one roller being driven by at least one motor, so that the device can be moved on the rope, wherein the at least one motor can be controlled in such a way that the device reproducibly moves to predeterminable positions on the rope, is characterized in that at least one liquid is applied to the rope at least at times, at least in some areas.

A preferred embodiment of the method according to the invention is in which a rope to be inspected is driven over with an inspection device which carries at least one inspection device for recording data for characterizing the condition of the rope, the inspection device comprising at least three rollers which are non-positively connected to the rope, wherein at least one roller is driven by at least one motor, so that the inspection device can be moved on the rope, is characterized in that the at least one motor can be controlled in such a way that the inspection device reproducibly approaches predetermined positions on the rope and data for characterizing the condition of the rope is recorded at least temporarily.

The inspection device can be part of the device for driving on the rope according to the method according to the invention or it can be part of an inspection device. The term “rope” in the sense of the present invention is understood to mean an element which is suitable for absorbing tensile forces. In particular, the term “rope” includes a rope and a rod, such as those installed in rope or suspension bridges and/or also a plurality of ropes, which together form such a rope for a rope or suspension bridge and which are in particular in a pipe , preferably made of metal and / or a plastic. The device is unmanned, so it automatically moves along the rope, especially when installed as a support rope on suspension bridges. The device is in contact with the rope through the at least three, preferably four, rollers. This creates a frictional connection between the rollers and the rope. All rollers can preferably be driven with a common or roller-specific motor and are driven in this way. By driving at least one roller, the device is moved on the rope. By appropriately controlling the motor, which includes, for example, a stepper motor and/or based on data from a corresponding sensor for position determination, a reproducible control of a specific position on the rope and/or position-resolved data recording on the rope takes place.

This means that, for example, after completing a total journey along a rope of several 100 m or even more than 1 km in length, a very specific position on the rope, which can be defined, for example, as the distance from a rope suspension and/or a marking on the rope, can be approached is to inspect a specific defect or the surface condition at that location more closely or to treat it with liquid, for example with repair solution for a damaged coating. This means that changes in condition that occur over time can be observed with great precision and in a position-resolved manner, even during successive inspections. In particular, it is possible to return to the position on the rope with an accuracy of 5 mm and better. With this procedure, even large rope lengths can be inspected regularly and reproducibly. The data for characterizing the condition of the rope can be recorded at predetermined time and/or location intervals or even continuously.

The liquid, which can consist of one or more components, can in particular be paint, a coating, a contact liquid and/or an analysis liquid with which the rope or its coating can be examined for possible errors or anomalies. A contact liquid is also understood to mean, in particular, a liquid via which contact with an analysis device, for example an ultrasound device, can be established. In the case of a contact fluid for the use of an ultrasonic sensor, the contact fluid serves in particular to couple the ultrasonic signal into the upper surface layers on the rope. In particular, the contact liquid comprises a liquid with a higher viscosity than that of water in the temperature range of 5°C (degrees Celsius) to 50°C. The contact liquid is preferably applied in such a way that a layer of contact liquid is formed between an ultrasonic sensor and the rope.

According to an advantageous development of the method according to the invention, the contact force of the rollers on the rope is controlled.

In particular, this can be done based on the slip data of the rollers on the rope. The contact force is controlled in particular depending on the surface quality of the rope and in particular its corrosion protection, which must not be damaged. The contact pressure of the rollers can be varied using appropriate pressure motors or manually by appropriately pre-tensioning elastic elements on the roller suspensions and the roller material.

According to a further advantageous embodiment of the method according to the invention, the pendulum shear stress on the rope is less than 2% (percent) of the tensile adhesive strength of the surface layer, preferably a paint, on the rope.

2. b) die Regelung der Anpresskraft der Rollen;
3. c) die Auswahl des Materials der Rollen;
4. d) die Einstellung der Anlagefläche der Rolle an dem Seil;
5. e) die Begrenzung der Beschleunigungen und/oder Antriebskräfte;
6. f) eine Dämpfung von Torkelbewegung in den Rollenlagern
7. g) die Führung von Leitungen hin zu der Vorrichtung und/oder Inspektionsvorrichtung, insbesondere von mindestens einer Versorgungsleitung und/oder Datenleitung;
8. h) Reinigung und Trocknung der Seiloberfläche vor den Rollen

This can prevent the rope from being damaged by the device and/or inspection device being driven over it. Pendulum shear stresses of less than 20, in particular less than 10% or even less than 2% of the tensile adhesive strength of the surface layer on the rope are particularly preferred. The pendulum shear stress arises from the combination of the drive torque with rolling and pendulum movements of the device and/or inspection device on and/or on the rope, which leads to shearing of the rope. The pendulum shear stress can be adjusted in particular by one of the following measures:

1. a) the adjustment of the contact pressure of the rollers;
2. b) regulating the contact pressure of the rollers;
3. c) the selection of the material of the rolls;
4. d) the adjustment of the contact surface of the pulley on the rope;
5. e) the limitation of accelerations and/or driving forces;
6. f) dampening of rocking motion in the roller bearings
7. g) the routing of lines to the device and/or inspection device, in particular of at least one supply line and/or data line;
8. h) Cleaning and drying of the rope surface in front of the rollers

Point h refers in particular to the mechanical cleaning of the rope using small brushes and scrapers that are mounted in front of the rollers.

1. a) mittels Magnetfelddetektion;
2. b) auf optischem Wege;
3. c) durch Aufnahme von Schwingungen;
4. d) durch Messung einer Schichtdicke mindestens einer oberflächennahen Schicht;
5. e) Ultraschallmessungen; und
6. f) Messungen der Materialhärte.

According to an advantageous embodiment of the method according to the invention, the data is recorded in at least one of the following ways:

1. a) using magnetic field detection;
2. b) optically;
3. c) by absorbing vibrations;
4. d) by measuring a layer thickness of at least one layer close to the surface;
5. e) Ultrasound measurements; and
6. f) Measurements of material hardness.

Magnetic field detection is the measurement of induced magnetic fields in the rope. Measurements by optical means include in particular the recording of Data using one or more image capture devices, such as. B. Cameras understood. The vibration modes can be recorded in particular by appropriately designed inertial sensors. Measuring a layer thickness of a layer close to the surface is, in particular, the determination of the layer thickness of a paint and/or the corrosion protection layers, such as. B. Galvanizing on a rope using magnetic or eddy current processes. Ultrasonic measurements refer to the introduction of an ultrasonic signal into the rope surface and measurement of its reflection on boundary layers, the disturbances of which are thus mapped. Measurements of the material hardness can be carried out in particular on the corrosion protection layer and/or a coat of paint on the rope and/or underlying layers, preferably using appropriately designed sensors, in which a defined force is exerted on the rope on a defined surface using a corresponding probe and the corresponding deformation resistance of the material is determined.

According to a further advantageous embodiment of the method according to the invention, the data is transmitted to a receiver.

This transmission can be carried out in particular wirelessly, for example via the formation of a wireless network (W-LAN) or wired. The receiver can preferably be designed on the ground or on the surface of the structure to be inspected, for example the bridge. Due to the often large amount of data to be transmitted, the long transmission distances and the design of the cables, which are usually made of steel with the corresponding electromagnetic interference, a wired transmission to the receiver is preferred. Commercially available and special network cables can be used for this. Furthermore, the device and/or inspection device is preferably to be supplied with power via the same or a different cable in order to save weight in the construction of the device and/or inspection device by saving the weight of the accumulators or batteries.

According to a further advantageous embodiment, location information is recorded with the data, which is correlated with the position on the rope when the data was recorded.

This can in particular be specifications of the stepper motor, for example a number of steps taken. It can also be data from an angle encoder that detects the roller rotations. Furthermore, it is alternatively or additionally possible to record calibration or calibration data of the location information, in which, for example, the distance traveled on the rope is recorded and saved after a certain initialization.

1. a) durch Aufsprühen,
2. b) durch Bepinseln und
3. c) durch Aufrollen.

According to a further advantageous embodiment of the method according to the invention, the liquid is applied by at least one of the following ways:

1. a) by spraying,
2. b) by brushing and
3. c) by rolling up.

Applying liquid by spraying is particularly suitable for ropes with a rough or structured surface, as the liquid can easily get into small spaces can be introduced into the rope surface. In addition, the wear on the nozzles for spraying the liquid is comparatively low.

When processing a liquid with a high viscosity, it is preferably applied to the rope by brushing or rolling it up.

1. a) gleichzeitiges Aufsprühen mindestens zweier Komponenten auf die Seiloberfläche;
2. b) Aufsprühen der Komponenten auf die Seiloberfläche mit kurzem zeitlichem Abstand; und
3. c) Vermischung in einem Mischer.

According to a further advantageous embodiment of the method according to the invention, in which the liquid consists of at least two components, the components are mixed by at least one of the following ways:

1. a) simultaneous spraying of at least two components onto the rope surface;
2. b) spraying the components onto the rope surface at short intervals; and
3. c) Mixing in a mixer.

The three types mentioned all have in common that there is only a short period of time between the mixing of the components and the application of the liquid, so that the components only react with one another for a short time at most before they are applied to the rope surface. For example, this prevents the liquid from drying out. Depending on the properties of the liquid, such as viscosity or reactivity, a corresponding type of mixing is used, for example mixing in a mixer for very viscous liquids for which spraying is difficult.

2. b) Reinigung des Seils;
3. c) Reparatur von Beschichtungen des Seils;
4. d) Auftrag von Beschichtungen auf das Seil; und
5. e) Markierung des Seils.

1. a) examinations of the rope;
2. b) cleaning the rope;
3. c) Repair of coatings on the rope;
4. d) application of coatings to the rope; and
5. e) Marking the rope.

For example, two-color inspection systems are used to detect cracks in the rope. Here, two different liquids are applied one after the other to the rope, which react with each other and can reveal cracks in weld seams through a color change. Furthermore, indicator liquids are used that react with deposits or corrosion products on the rope and also indicate these through a color change.

To clean ropes, for example, water, which is mixed with cleaning additives if necessary, surfactants and/or solvent mixtures are used.

The method according to the invention is also suitable for repairing coatings and for applying coatings to the rope. For this purpose, several layers and components of a corrosion protection and coating system used can be applied in one or more components to the rope surface at predetermined positions in one or more operations over larger areas. In this way, either individual sections, which can be limited in length and circumference of the rope, or the entire rope are treated.

Furthermore, with the method according to the invention, several layers or components of a paint system can be applied to selected positions in one or more operations in points or lines for marking or labeling the ropes on their surfaces.
