[0002] Method and apparatus for rope processing

[0003] The invention relates to a method and a device for rope processing, wherein a rope is traversed by the device, comprising controlling at least one motor to move the device on the rope to a predetermined position, applying at least one fluid, comprising cleaning, washing and / or coating, at least in partial areas of the rope, in particular at the predetermined position, and removing solid or loose deposits or a coating on the rope.

[0004] Ropes or rods are used to transmit tensile forces in technical structures, particularly high-rise buildings such as suspension bridges, cable-stayed bridges, or roof structures. Such ropes can be designed as cables or rope bundles, especially as fully locked cables (WS) or stranded cables. When installed, the individual ropes, the strands of a cable, or rope bundles are provided with corrosion protection in the form of coatings, wrappings, or plastic sheathing. For this purpose, the strands of the ropes are either individually galvanized and then coated with a coating system after installation, or the strand bundles are coated directly after installation.

[0005] These corrosion protection systems applied to ropes typically have a protection period according to ISO 12944-1 ranging from high (25 years) to very high (over 25 years). This means that after reaching the end of the protection period, the corrosion protection coatings must be repaired according to ISO 12944-1, either by partial or complete renewal.

[0006] Since the surfaces of the cables can become weathered or heavily soiled after prolonged periods of inactivity, repairs may be necessary during the cables' service life. Regular inspections are required to prevent the risk to third parties and the structures themselves from unexpected cable or rod breaks.

[0007] For repair, partial renewal, or complete renewal work on ropes, the coverings or coatings of the ropes, cables, or rope bundles are treated. Before applying a new coating, surface preparation work is necessary. This is generally carried out according to ISO 8504-3 using hand tools or power tools. A complete renewal of the corrosion protection coating is generally carried out by blasting according to ISO 8504-2.

[0008] Previously, this work on ropes was carried out using manned inspection equipment and aerial work platforms. Therefore, unmanned inspection equipment is proposed, for example, in EP 23 25 394 A2 and utility model DE 2020 17 001 708 U1. However, the methods and devices described therein only include cleaning or coating (EP 2325394) or blasting (DE 2020 17 001 708 U1) the ropes.

[0009] Therefore, the devices and methods of the prior art do not allow for the performance of repair work, partial renewal or complete renewal of corrosion protection of ropes, which includes removal and cleaning or coating.

[0010] It is therefore the object of the invention to provide a method and a device for rope processing that enables repair work, partial renewal and / or complete renewal of corrosion protection of ropes, comprising removal and coating, washing or cleaning.

[0011] This problem is solved by a method having the features of claim 1. Dependent claim 13 relates to a corresponding device. Advantageous embodiments of the invention are the subject of the dependent claims.

[0012] Accordingly, a method for rope processing is provided in which a rope is traversed by a device comprising a drive unit with at least three rollers which are frictionally connected to the rope, wherein at least one roller is driven by at least one motor, and which comprises the steps:

[0013] Controlling the at least one motor to move the device along the rope to a predetermined position, at least temporarily applying at least one fluid to the rope at least in partial areas of the rope, in particular at the predetermined position, wherein the temporary application includes cleaning, washing and / or coating the rope, and

[0014] Removal of solid or loose deposits or coatings on the rope.

[0015] Because the process involves material removal, it can be used for surface preparation during repair work, partial renewal, or complete renewal of the corrosion protection coating on ropes such as cables or other cables. Furthermore, the process also allows for cleaning, washing, and / or coating of the rope by at least temporarily applying a fluid. Thus, the invention enables the execution of several, preferably all, steps required for repair work, partial renewal, or complete renewal of the corrosion protection coating on ropes.

[0016] The control of at least one motor can be achieved by means of a control unit. This unit can either be integrated into the device itself or be a separate component. In the latter case, the external control unit is connected to the device via a signal. If the control unit is integrated into the device itself, an input unit can be provided on the device, allowing, for example, the user to specify a predetermined position and / or select the work steps to be performed.

[0017] In particular, the device may be equipped with sensors, such as a camera, so that the condition of the rope can be detected during its movement along the rope. Based on the detected condition, the control unit can automatically perform appropriate process steps, such as removal and recoating. Alternatively or additionally, the detected condition can be transmitted to an external data unit. This allows, for example, an operator of the device to assess the condition of the rope based on the transmitted data. Based on this assessment, the operator can use an external control unit to move the device to a desired position and perform suitable processing steps according to the condition of the rope.

[0018] Fluids are understood here to be liquids and gases that are particularly suitable for cleaning, washing and / or coating ropes.

[0019] Preferably, the removal process includes blasting the rope. This allows for the automated removal of a coating from the ropes, i.e., without manual guidance of a beam by a person. In particular, it can be provided that the removed material and / or media applied by blasting are collected, for example, in a collection tray of the device. This allows the process to be carried out without the need for scaffolding or enclosure of the ropes. The blasting can preferably be performed using compressed air blasting, vacuum blasting, suction head blasting, or laser beams.

[0020] Blasting media can consist of granules or powders of solid material, which can alternatively also consist of frozen liquids or frozen gases, and may contain additives such as surfactants, which are sprayed onto a surface of the ropes under high pressure using air or water or a mixture of air and water.

[0021] In compressed air blasting, the blasting medium used to treat surfaces is accelerated by compressed air as it flows through a nozzle. The impact of the blasting medium on the rope's surface can alter its condition, for example, by removing a coating. Suction head blasting is similar to compressed air blasting, except that the resulting blasting debris is extracted within the suction head.

[0022] In vacuum blasting, a suction device is used to accelerate the blasting medium. The process therefore takes place exclusively under negative pressure. This makes the process dust- and spark-free in relation to the surrounding environment: removed particles, along with the blasting medium, can be directly extracted by an airflow and, if necessary, filtered.

[0023] Laser ablation involves the removal of material using high-power laser radiation, particularly pulsed laser radiation. This rapidly heats the surface being processed, causing the material to be ablated. Laser ablation is therefore also referred to as laser evaporation. Laser ablation is characterized by its gentle removal process because only the outermost layer, which is only a few micrometers thick, is intensely heated; the workpiece, in this case the rope, remains cold. Another advantage is that no radiant medium is required, meaning only the ablated material needs to be removed.

[0024] Preferably, the method includes the extraction of removed or applied media, such as removed particles of a coating or applied blasting media. This prevents or at least reduces dust formation in the surrounding area. In particular, extraction can be carried out by applying a vacuum. The removed or applied media can be extracted into a collection tray.

[0025] Furthermore, the removal process can include grinding or brushing the rope. This allows for the removal of coatings or contaminants from the rope without the need for an additional medium such as an abrasive. Brushing the rope can be done using wire brushes. Preferably, this brushing process includes pre-tensioning the wires of the wire brushes.

[0026] Preferably, the application process includes cleaning the rope by applying at least one fluid at a maximum pressure of 70 MPa (megapascals). This allows for surface preparation of the ropes. The applied fluid can be collected in a drip tray. The limited pressure enables cleaning with lower energy consumption, making it particularly suitable for lighter soiling. Alternatively or additionally, the application process can include washing the rope by applying at least one fluid at a pressure of 70 to 210 MPa. This also allows for surface preparation of the ropes. The applied fluid can be collected in a drip tray. The increased pressure allows for thorough washing of the ropes, making it particularly suitable for stubborn soiling.

[0027] Cleaning and / or washing is preferably carried out by applying water. This allows for a simple process, as water is usually readily available. To improve cleaning or washing, appropriate additives can be mixed with the water.

[0028] Preferably, the application process comprises coating the rope with a primer and / or topcoat. It is also possible to apply multiple primers and / or topcoats, and in particular, one or more intermediate coats. The coating is preferably applied by brushing, especially rotary brushing, or by spraying, especially an airless spraying process or an electrostatic spraying process. An airless spraying process is a spraying process in which the spray material is atomized by high pressure without the need for air and applied to the rope.

[0029] Preferably, the method comprises connecting a tool unit to the device and / or exchanging a connected tool unit for application and / or removal. This allows the invention to be carried out flexibly. Instead of tool units having to be arranged in the device simultaneously for all steps to be performed, a connected tool unit can be exchanged after completion of a step.

[0030] For example, it may be possible to first remove material using a tool unit comprising wire brushes. After the material removal is complete, the tool unit comprising wire brushes is replaced with a tool unit comprising a brush. The tool unit comprising a brush can then be used to apply a fluid, such as a coating, to the area treated with the wire brushes.

[0031] In particular, for rope repair work, it may be possible to combine the described configurations of the process steps. Individual steps and their configurations can also be carried out repeatedly. The device may include several tool units for performing multiple process steps and / or allow for the exchange of tool units.

[0032] Repair work on corrosion protection coatings of ropes includes, according to a method using a device positioned at a predetermined location on the rope to be treated, such as a cable or a cable, repair work on the rope by means of grinding or brushing. This allows individual rust penetrations in the corrosion protection coatings to be ground or brushed, for example with rotating wire brushes, and thus prepared according to ISO 12944-4.

[0033] After these preparatory works, the prepared damaged areas in the coating are repaired by painting the rope with a matching coating system.

[0034] Partial renewal of corrosion protection coatings on a rope, such as a cable or wire rope, can, following an initial process using the device, include cleaning the rope and removing rust penetrations in the existing old coating by brushing or blasting. The prepared damaged areas can then be treated by applying one or two primer coats. After further cleaning with water, the rope subsequently receives a topcoat by airless spraying, electrostatic spraying, or brushing. Thus, using the method according to the invention, a renewed protection period high according to ISO 12944-1 can be achieved.

[0035] A complete renewal of corrosion protection coatings on ropes such as WS or cables can, after an initial process using the device, include the removal of the old coating by blasting. Subsequently, one or more primer coatings can be applied by brushing. Finally, any further necessary coatings can be applied either by brushing, electrostatic spraying, or airless spraying. Thus, using the method according to the invention, a renewed protection period of high to very high according to ISO 12944-1 can be achieved.

[0036] A further aspect of the invention relates to a device for rope processing, in particular with a method according to the invention, comprising a drive unit, a control unit, and a tool system, wherein the drive unit has at least three rollers and at least one motor, the rollers can be frictionally connected to a rope to be processed, and at least one roller can be driven by the motor. The control unit is designed and configured to control the motor of the control unit. The tool system is designed and configured for applying at least one fluid to the rope, at least in partial areas of the rope, wherein the application includes cleaning, washing, and / or coating the rope, and for removing solid or loose deposits or a coating.

[0037] The drive unit enables the device to be moved along the rope, for example, a cable or wire. The drive unit can be adapted to different diameters of the cable or wire. This can be achieved, for example, by controlling the contact force of the rollers against the rope.

[0038] The tool system can be connected to the drive unit, so that drive energy for the tool system can be supplied via the drive unit. The tool heads of the tool system can be adjustable, allowing them to be aligned for machining a specific point on the workpiece or cable, for example by rotating the tool heads.

[0039] The control unit can be a single component or a multi-component unit. In a single-component design, the control unit can be located within the device, for example, the drive unit. In this case, an operating unit for the control unit can be provided on an outer surface of the device, allowing input of parameters such as predefined positions and process steps. In a multi-component design, an internal and an external control unit can be provided. The internal control unit is located within the device and includes an actuator for controlling the motor and a data interface. The internal control unit is connected to the external control unit via this data interface. This connection can be wired or wireless. The external control unit is located outside the device and can therefore be operated by a user.The device can be controlled via the external control unit.

[0040] Furthermore, the internal control unit can be configured to collect data from sensors on the device, such as a camera, and transmit it to the external control unit. This allows an operator, for example, to detect the condition of the rope and, based on this condition, specify appropriate application and / or removal process steps to the device.

[0041] Preferably, the tooling system comprises at least two tool units and / or at least one interchangeable tool unit. This enables the device to perform both material removal and application using a single tooling system and thus a single device. For example, if the tooling system comprises one tool unit for material removal and one tool unit for application, material removal and application can be performed directly. Alternatively, material removal can be performed first, followed by replacement of the tool unit. Application can then be carried out with the newly inserted tool unit. A combination of these configurations is also covered by the invention. For instance, the tooling system can comprise two tool units, at least one of which is interchangeable.For example, a tool unit for applying material and a tool unit for removing material may be provided, with the tool unit for removing material being interchangeable in order to adapt the type of removal to a condition of the rope and / or a processing method, such as repair work, partial or complete renewal.

[0042] Preferably, a tool unit of the tool system is configured as a grinding unit, wire brush unit, blasting system, cleaning unit, painting unit, and / or spraying unit. Preferably, the tool system and / or the tool unit has an enclosure to prevent contaminants from entering the environment. In particular, a collection tray and / or an extraction system may be provided.

[0043] The grinding unit is designed and set up for grinding the rope. For this purpose, it can include pads made of synthetic fabric with integrated abrasive and sanding cloth or sandpaper.

[0044] The wire brush unit is designed and configured for brushing the rope. For this purpose, it may include rotating wire brushes. A pre-tensioning of the wire brushes may be provided.

[0045] The blasting system is designed and configured for blasting the rope. For this purpose, it can be implemented as a compressed air blasting unit. The compressed air blasting unit feeds a blasting medium into a stream of compressed air, which is then directed at high speed from one or more nozzles of the compressed air blasting unit onto the surface of the rope to be cleaned. The compressed air blasting unit preferably has an enclosure around the nozzles to prevent any blasting debris from escaping. Furthermore, the compressed air blasting unit can preferably include a system for extracting the blasting debris, in particular by applying a vacuum.

[0046] Alternatively, the blasting system can be designed as a suction head blasting unit. In this case, one or more blasting nozzles are arranged in a suction head that rests tightly on the surface of the rope and sucks up used blasting media and contaminants (blast debris) by means of a vacuum.

[0047] The cleaning unit is designed and configured for cleaning or washing the rope. For this purpose, the cleaning unit comprises several nozzles through which it applies a fluid, in particular water or a water-based solution, to the rope's surface at pressures up to 70 MPa for cleaning or at pressures from 70 MPa to 210 MPa for washing. This allows for surface preparation of the rope according to ISO 8504-5. Preferably, water with a fine abrasive, particularly a dispersion, is used as the fluid. The cleaning unit may include an enclosure and a container, such as a collection tray, to collect the cleaning fluid and dissolved contaminants.

[0048] The coating unit is designed and equipped for coating the rope. For this purpose, the coating unit can have one or more brushes, particularly rotating ones. Prepared damaged areas can thus be coated with a primer, intermediate, and / or topcoat by the coating unit.

[0049] The spraying unit is designed for spraying the rope. For this purpose, the spraying unit can have one or more spray nozzles, preferably airless sprayers. The spraying unit can also be designed for an electrostatic spraying process. Prepared damaged areas can thus be coated with a primer, intermediate, and / or topcoat by the spraying unit.

[0050] The device according to the invention is particularly suitable for carrying out the method according to the invention. The details and advantages disclosed for the method according to the invention are transferable and applicable to the device according to the invention, and vice versa.

[0051] Further details of the invention are explained with reference to the figures below. These show:

[0055] Figure 5 shows a front view (bottom left), perspective view (bottom right) and side view (top) of a tool device with a brush attachment according to an embodiment of the invention; and

[0056] Figure 6 shows a schematic representation of a device for rope processing with an external control unit according to an embodiment of the invention.

[0057] Figure 1 shows a perspective view of a device according to the invention for rope processing. The device comprises a drive unit 10 and a tool system 30. The drive unit 10 is arranged in front of the tool system 30 in a forward direction of movement s of the device 1. Locking elements 32 designed as a toggle lock are provided for securely connecting the tool system 30 to the drive unit.

[0058] The drive unit 10 comprises a drive box 13 and a superstructure 14, which is closed off at the top by a cover plate 15. The cover plate 15 has a handle 16 by which the device 1 can be carried and, for example, placed on or removed from a rope 100.

[0059] The superstructure 14 has two side panels 17 which are movably mounted at a lower edge so that they can be opened by pulling a handle 18. This provides access to the interior of the drive unit 10. To prevent the side panels 17 from opening unintentionally, each panel has two rotatable locking units 19 by means of which they can be locked or unlocked in a housing of the superstructure 14.

[0060] Figure 2 shows the device 1 with a disassembled tool system 30. In particular, a gear 110 and ten suspensions 111 are visible in the upper rear view. The gear 110 drives the tool units 31 of the tool system 30 from the drive unit 10. The suspensions 111 facilitate the assembly and disassembly of the tool system 30 by, for example, first placing the tool system 30 onto the suspensions 111 for assembly and then securing it using the two locking elements 32.

[0061] Furthermore, locking elements 112 designed as toggle latches are shown, by means of which the drive box 13 can be connected to the superstructure 14 in a force-fit and form-fit manner. By opening the locking elements 112, the drive box 13 can be removed from the superstructure. For this purpose, the drive box 13 also has handles 113. Thus, the drive box 13 can be replaced in the event of a defect or for maintenance.

[0062] Figure 3 shows the device 1 as in Figure 1 with the tool system 30 attached, shown below in a rear view and above in a sectional view. The sectional view shows four rollers 11 and a motor 12 of the drive unit 10. The rollers 11 can be frictionally connected to a rope 100 to be processed, and at least one roller 11 can be driven by the motor 12.

[0063] Furthermore, the drive unit includes an internal control unit 20, which here forms a unit with a power supply for the motor 12 designed as a battery. The internal control unit 20 includes an actuator for driving the motor 12 and a data interface via which it can communicate with an external control unit. Thus, the internal control unit 20 can both receive commands from the external control unit and send data to the external control unit.

[0064] For this purpose, the device 1 includes a camera hood 40. This hood has a camera by means of which the condition of the rope 100 can be detected. The optical data detected by the camera can be recorded by the internal control unit 20 and sent to the external control unit. There, the optical data can be used to evaluate the condition of the rope 100. Based on this evaluation, a procedure to be carried out by means of the device 1 can then be determined.

[0065] The drive unit 10 can also include a gearbox 114 for adjusting the roller speed. Furthermore, it can be equipped with a control mechanism for the contact force of the rollers on the rope 100. The motor 12 can also be used to drive the gear 110. A gearbox can also be interposed here.

[0066] The rear view shown below depicts a tool unit 31 designed as a brushing unit. This unit has four brushes 33. A collection tray 34 is arranged below the tool unit 31. This tray is designed to collect excess fluid applied by the tool unit 31 and / or removed contaminants. The collection tray 34 is attached to the upper part of the tool system 30 by means of two locking elements 35 designed as toggle fasteners.

[0067] Figure 4 shows the tool unit 31, designed as a brushing unit, in detail. The brushing unit 31 is shown in an exploded view in the upper and lower right illustrations. A front view is shown in the lower left. This shows that brushes 33 are inserted into a brush holder 36, where they can be secured by bolts or screws. The brush holder 36 is mounted on a toothed ring 37, which is fastened to a bearing ring 39 by countersunk screws 38. The toothed ring 37 is driven by the gear 110, causing the brushes 33 to rotate. The extensive arrangement of the brushes 33 and the rotating motion ensure the most even and complete application of a fluid to the rope 100.

[0068] Brush holder 36 and toothed ring 37 are made of a thermoplastic material, specifically POM (polyoxymethylene, also known as polyacetal). This material is characterized by high mechanical strength and rigidity. Furthermore, it exhibits very good sliding properties, excellent wear resistance, and low moisture absorption. The bearing ring is made of aluminum. The twelve countersunk screws have an internal hexagon socket and are made of stainless steel.

[0069] Figure 5 shows a tool unit 31 designed as a wire brush unit. The wire brush unit 31 is shown in an exploded view in the upper and lower right illustrations. A front view is shown in the lower left. This shows that brush heads 41 can be attached to inserts 42. The inserts 42 are identical in shape to the brushes 33 of the coating unit in Figure 4 in that they can be inserted into the brush holder 36. Therefore, to replace the tool unit 31, only the brushes 33 need to be exchanged for the brush heads 41 attached to the inserts 42. Thus, the tool unit 31 can be used for both applying a coating and removing solid or loose deposits.

[0070] In embodiments not shown, the tool unit 31 may alternatively or additionally include a grinding unit, a blasting system, a cleaning unit and / or an injection unit.

[0071] Figure 6 shows a schematic representation of a device 1 for rope processing with an external control unit 21. The device 1 is mounted on a rope 100. This rope runs from a ground to the top of a pillar 101 and then continues in a horizontal direction.

[0072] The external control unit 21 allows an operator to control the device 1. The external control unit 21 can thus receive data from an internal control unit 20 of the device.

[0073] 1. Received, which, for example, can provide information about the condition of rope 100. If the operator thus determines that repair work on corrosion protection coatings is required at one or more predetermined locations.

[0074] If repairs are required at position 2 of the rope 100, the operator can move the device 1 to the corresponding position 2 of the rope 100. There, the operator can then carry out repair work using the device 1, for example by brushing the rope 100 using the wire brush unit 31 shown in Figure 5. This allows individual rust penetrations in the corrosion protection coatings to be brushed with the rotating wire brushes 41 and thus prepared according to ISO 12944-4.

[0075] After these preparatory works, the prepared damaged areas in the coating are repaired by applying a suitable coating system to the rope 100. For this purpose, the operator can return the device 1 to the ground and replace the brush heads 41 with brushes 33. Replacement tool units 31 can be stored, for example, in a storage unit 102. With the brush unit 31 thus provided, as shown in Figure 4, the operator can move the device 1 back to the corresponding positions of the rope 100 and apply a coating fluid using the rotating brushes 33.

[0076] Partial renewal of the corrosion protection coatings on the rope 100 can also be carried out in this way. After an initial positioning of the device 1 at a predetermined location on the rope 100, the process can include cleaning the rope 100 using an additional cleaning unit integrated into the tool system and removing rust penetrations in the existing old coating using the rotating brushes 41. The prepared damaged areas can then be coated with one or two primer coats by brushing with the brushes 33. After further cleaning with water, the ropes subsequently receive a topcoat by brushing with the brushes 33 or by spraying, for example, low-pressure compressed air spraying, airless spraying, or electrostatic spraying. In this way, a renewed high level of protection according to ISO 12944-1 can be achieved.

[0077] A complete renewal of the corrosion protection coatings of the rope can be carried out using an initial process of the device 1 by removing the old coating by blasting. For this purpose, the tool system includes a corresponding tool unit 31 designed as a blasting unit. Subsequently, one or more primer coatings can be applied using the brushes 33. Finally, any further required coatings can also be applied using the brushes 33 or by spraying, for example, low-pressure compressed air spraying, airless spraying, or electrostatic spraying. Thus, a renewed protection period of high to very high according to ISO 12944-1 can be achieved using the method according to the invention.
