Definitions

  • the subject of the present invention is a method for inspecting ropes and an inspection device for inspecting ropes.
  • Method and inspection device can be used in particular for the inspection of load-bearing ropes, as used for example on bridges or similar structures.
  • Ropes or bars which are installed to transfer tensile forces stationary into technical structures, such as rope or suspension bridges, must be inspected regularly to prevent the risk to third parties and the structures themselves by unexpected ruptures of ropes or rods. So far, inspections of these ropes or bars have taken place via manned inspection equipment or aerial work platforms. Unmanned inspection devices are known, for example from the DE 203 11 395 U 1 ,
  • the inventive method for inspecting ropes in which a rope to be inspected is driven by an inspection device which carries at least one inspection device for receiving data for characterizing the state of the cable, wherein the inspection device comprises at least three rollers which are non-positively connected to the cable, wherein at least one roller is driven by at least one motor, so that the inspection device is movable on the rope, is characterized in that the at least one motor is controlled so that the inspection device anfbarer positions on the rope reproducibly anastronom and wherein at least temporarily data for State characterization of the rope to be recorded.
  • rope in the sense of the present invention is understood to mean an element which is suitable for absorbing tensile forces.
  • the term “rope” includes a rope and a rod, as they are installed, for example, in rope or suspension bridges.
  • condition characterization is understood to mean data that is characteristic of the condition of the rope or parts of the rope, such as the condition of a corrosion protection layer on the rope, the integrity of individual wires of the rope, surface corrosion of the rope, and others.
  • the inspection device is unmanned, so it can drive automatically or remotely controlled the rope. By at least three, preferably four roles, the inspection device is in contact with the rope. In this case, a non-positive connection between the rollers and the rope is generated.
  • all roles are driven by a common or role-specific engine and are driven so.
  • the inspection device is moved on the rope.
  • a corresponding control of the motor for example, a stepper motor includes and / or based on data of a corresponding sensor for position determination, a reproducible control of a specific position on the rope and / or a position-resolved data acquisition takes place on the rope.
  • the pressing force of the rollers is controlled to the rope.
  • this can be done based on the slip data of the roles on the rope.
  • the control of the contact pressure is carried out in particular depending on the surface condition of the rope and in particular its corrosion protection, which must not be damaged.
  • the contact force of the rollers can be varied by appropriate Anpressmotoren or manually by a corresponding bias of elastic elements on the roller suspensions and the roll material.
  • the pendulum shear stress of the rope is less than 2% (percent) of the adhesive tensile strength of the surface layer, preferably a paint, on the rope.
  • point h can be understood to mean the cleaning of the rope by small brushes and wipers mounted in front of the rollers.
  • Magnetic field detection is the measurement of induced magnetic fields in the cable. Under measurements by optical means, in particular the recording of data by means of one or more image recording devices, such as. B. cameras understood. The recording of the vibration modes can be done in particular by appropriately trained inertial sensors. By measuring a layer thickness of a layer near the surface, in particular the determination of the layer thickness of a paint and / or the corrosion protection layers, such. B. galvanizing on a rope understood by magnetic or eddy current method. By ultrasound measurements, the introduction of an ultrasound signal into the cable surface and measurement of its reflection at boundary layers are called whose disturbances are thus imaged.
  • Measurements of the hardness of the material can be made, in particular, on a corrosion protection layer and / or a coat of the rope and / or underlying layers, preferably by suitably designed sensors in which a defined force is exerted on the cable with a corresponding probe on a defined surface and the corresponding deformation resistance of the material is determined.
  • the data is transmitted to a receiver.
  • This transmission can in particular be wireless, for example via the formation of a wireless network (W-LAN) or wired.
  • WLAN wireless network
  • the receiver may preferably be formed on the floor 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 transfer paths and the design of the cables 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 purpose.
  • the inspection device is preferably to supply power via the same or another cable so as to save weight in the construction of the inspection device by saving the weight of the batteries or batteries.
  • location information is recorded with the data, which are correlated with the position on the cable during the recording of the data.
  • These may in particular be specifications of the stepping motor, for example a number of steps taken. It may also be data from an angle encoder that detects the roll 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 is recorded on the cable after a specific initialization and stored with it.
  • an inspection device for inspecting ropes which comprises at least three rollers by means of which the rope to be inspected is to be driven with the inspection device and furthermore comprises at least one inspection device for receiving data for state characterization of the rope. At least one roller is drivable by a motor, so that the inspection device can be moved on the rope.
  • a control means is formed, by means of which the motor is controlled so that predeterminable positions on the rope are reproducibly approached.
  • contact pressure for pressing the rollers are formed on the rope.
  • the contact pressure of the contact pressure on the rope is adjustable.
  • a sensor for measuring self-induced or externally induced local magnetic fields is a device by means of which a magnetic field can be induced in the rope to be inspected, which is subsequently measured. Disturbances of the existing or induced homogeneous magnetic field may indicate wire breaks in the rope.
  • the inspection device comprises a plurality of cameras and in particular several types of cameras, wherein preferably with a type of cameras a positionally accurate image, preferably a lower resolution, in particular for Simultaneously transferring and / or viewing the data for immediate local inspection of the rope while driving at higher speed of passage and recorded.
  • a second type of camera is designed for the high-resolution optical inspection of the rope in exact position after the drive.
  • At least one inspection device 10 is formed on a measuring device carrier 7. These inspection devices 10 include cameras 8 and magnetic field measuring devices 9. The rollers 6 are mounted in wheel suspensions 2. The data supplied by the inspection devices 10 and in particular the cameras 8 and magnetic field measuring devices 9 are evaluated in a measurement evaluation means 3 and possibly transmitted to a receiver (not shown). Further, a control means 4 is formed, by means of which the motor 5 is monitored and driven to drive the rollers 6. In this case, the control means 4 include position counters for determining location information, so that these can be correlated and stored with the data supplied by the inspection devices 10, and optionally thrust force sensors.
  • the inventive method and the inspection device A according to the invention allow a reproducible surface inspection of cables, for example, suspension bridges.
  • cables for example, suspension bridges.
  • the position and type of surface defects on the rope can be detected with automatic means and these can be found again.
