Definitions

  • the invention relates to a system for electrical contacting of tension members in suspension means to monitor suspension means in elevator systems.
  • belt-shaped suspension means In some conveyors such as elevator systems, cranes or hoists, belt-shaped suspension means are used. These support means generally comprise a plurality of beam wires consisting of tensile carriers which absorb the tensile forces to be absorbed by the suspension element.
  • the tension members are generally surrounded by a plastic sheath.
  • the jacket protects the tension members, for example against mechanical wear, because the support means are often guided over deflection points. In addition, the jacket improves the traction of the suspension element on deflection or drive rollers, and fixed the arrangement of the tension members with each other.
  • Such suspension means are within a conveyor a safety-critical component. Their failure, or breakage can lead to a fall of the good to be promoted. This can lead to considerable property damage or personal injury. For this reason, test units are used in conveyors, which in particular check the mechanical condition of the tension members. Damage to the forces absorbing tension members should be able to be detected early, so that the support means can be replaced in case of damage to prevent failure of the conveyor.
  • the tension members are surrounded by the electrically insulating jacket made of plastic.
  • contacting of a contact element with the tension member is required in some methods.
  • an electrical current is passed with the aid of the contact element through the tension members, which serves as a test current to determine the state of the tension members.
  • other test methods that do not use electric current, e.g. Ultrasound, into consideration.
  • the DE 3 934 654 A1 shows a generic support means.
  • the ends of the tension members are connected in pairs conductive with a bridge part, so that the tension members of the support means are electrically connected in series.
  • the tension members of the suspension element are over an ammeter connected to a voltage source, so that by means of the test current, which is passed through all train carrier due to the electrical circuit in series, the state of the tension members can be assessed.
  • the WO 2005/094249 A2 shows a system for contacting a support means, wherein the contact elements perpendicular to a longitudinal axis of the tension members pierce the jacket of the suspension element and then penetrate into the tension members.
  • the contact elements can miss the tension members due to the required piercing process through the jacket.
  • An object of the present invention is to provide a system for electrical contacting of tension members in support means available, in which the tension members of the support means can be reliably and accurately contacted by a contact element to determine a state of the tension members can.
  • the system should be easy to use and reliable and have low production costs.
  • a system for electrical contacting of tension members in suspension means which comprises a support means and a contacting device.
  • the suspension element has a jacket and at least four tension members, which are arranged parallel to one another in the jacket, and which lie essentially on one plane.
  • the contacting device has a contact element.
  • the contact element has a cutting side for penetrating the jacket, wherein the cutting side of the contact element is guided through the jacket such that the contact element contacts the at least four tension members at least with the cutting side.
  • the contact element with the cutting side also has the advantage that the contact element can be driven like a knife through the jacket to contact the tension members.
  • Such a cutting side may be formed, for example, as a straight edge, or as a serrated edge with contact tips or as an edge with contact recesses or contact increases.
  • Such contact tips or contact recesses or contact increases have the advantage that the tension members can each be reliably contacted by a contact tip or contact recess or contact increase.
  • a contact tip or contact depression or contact increase per tensile carrier is provided in each case. As a result, all tensile carriers of a suspension element can be reliably contacted with a single contact element.
  • the contacting device comprises a first and a second holding element.
  • the suspension element is arranged substantially between the first and the second holding element.
  • the contact element is supported by one of the two holding elements, so that the cutting side of the contact element is directed against the support means.
  • Such holding elements make it easier to guide the contact element in the desired manner by the jacket of the support means.
  • first and second retaining element are connected to each other by a first and a second fastening element.
  • the retaining elements can be guided relative to one another in order thereby to drive the contact element into the jacket of the suspension element.
  • a hinge and a fastening element are provided in order to connect the first and the second retaining element to one another.
  • the first and the second fastening element and the one fastening element are each designed as a screw with nut.
  • other embodiments are possible.

  • the support means 1 is fastened to a first support means fastening device 47, and then first guided around the support roller 46 of the counterweight 42. Then the support means 1 is placed over the traction sheave 43, guided around the support roller 46 of the car 41 and finally connected by a second suspension means fastening device 47 with a fixed point.

  • a contacting device 2 is arranged at both ends of the support means 1.
  • only one contacting device 2 is arranged on one of the support means ends 1.1.
  • the Tragstoffenden 1.1 are no longer burdened by the tensile force in the suspension element 1, since this tensile force is already passed through the support means fasteners 47 into the building.
