Definitions

  • the invention relates to a cable harness according to the preamble of the main claim.
  • Such machines are usually by means of lifting u.
  • Lowering agent lowered into a well shaft and installed there.
  • the supply lines necessary for the electric drive motors are generally inserted watertight in the motor or its junction box and must also be lowered into the well shaft during the lowering process. Due to the large number of different drive motors, different connection cables are used.
  • Control lines are also installed for those motors or the machines driven by them, which are equipped with a so-called monitoring device, which are connected to above-ground switching and monitoring devices. Since these control lines are very sensitive in contrast to the electrical connection cables, it must be ensured that these cables are reliably protected during the entire operating time.
  • the fastening clamps or the like have been found to be negative because they constrict the insulation material of the cables and excessive material fatigue occurs at these points, so that leaks or chafing occur after a certain time. Furthermore, with large installation depths, the weight of the cable can become too large and, in unfavorable cases, the insulation can detach from the live conductor and tear. Wrapping the cables together using suitable materials or bundles using rubber-lined clamps or routing the cables in separate pipes has proven to be of little use in the course of time.
  • the connecting cable between a welding machine and the welding gun is known from US Pat. No. 3,992,565.
  • a strand-shaped hollow profile has several cavities for receiving the pipelines, welding wires and welding cables necessary for the welding process.
  • the hollow profile completely envelops these parts and has longitudinal slots for receiving them.
  • a bandage closes the hollow profile.
  • the invention has for its object to develop a cable holder for machines that can be lowered into manholes, which is easy to attach and ensures reliable protection of the cables located within the manholes.
  • the machine to be lowered is provided with a rope firmly attached to it, which remains permanently connected to the unit and is suspended in the opening area of the well shaft after the unit has been lowered.
  • the elastic strand is pushed or pressed over this rope.
  • the cavity or cavities remaining within the strand take up the sensitive control cables or sensor lines and the actual power supply cables are placed on the outside of the strand and combined to form a uniform whole by means of a bandage known per se. This ensures reliable protection in a simple manner.
  • the arrangement of the sensitive control lines within the line protects them sufficiently against any damage and other external influences.
  • the integration of the steel cable lowering the machine into the cable harness and within the extruded profile results in a structure that is insensitive to any axial loads and prevents mutual damage.
  • An embodiment of the invention provides that one or more of the cavities are accessible from the outside through a longitudinal slot, known per se, which is provided in the strand.
  • the elastic strand can be supplied by the meter with the machine and either before or during the lowering process via the lifting and attaching to the machine.
  • Lowering means which can be a rope or a chain, pressed. The subsequent connection of the connecting cables to the strand and the attachment of the bandage is then only a simple operation.
  • the strand is formed in several parts.
  • the strand can be composed of different shell-shaped pieces in order to enable a corresponding adaptation to the number and shape of the cables used in each case.
  • the strand could consist of individual parts of approx. 1 - 2 m in length, which are then attached to the lifting means in succession.
  • Fig. 1 shows a cable harness in which the lifting and lowering means connected to the machine to be lowered, here a steel cable, is surrounded by an elastic profiled strand (2). Since the strand (2) is provided with longitudinal slots (3), it can be pressed in a simple manner over the lifting and lowering means (1), or a control cable (4) provided with different lines can be pressed into the strand.
  • Four further connecting cables (5) securing the power supply are located in the outer contour of the strand (2) in recesses (6).
  • a cohesive bandage (7) presses the parts together and brings about a secure cohesion of the individual parts.
  • the control cable (4) within the strand (2) it is reliably protected against damage or external influences.
  • Fig. 2 differs from Fig. 1 in that only a single connection cable (5) is attached outside the strand (2), within which the individual lines are housed.
  • a bandage (7) ensures secure cohesion.
  • the bandage (7) can consist of the known materials that ensure reliable protection against moisture and the like.
