Definitions

  • the invention relates to an oscillating head clamp for a column insulator of a medium-voltage overhead line, with a clamp body which is mounted in a fork-shaped fastening part so as to be rotatable about a defined pivot point.
  • Column insulators are insulators that are used to support and insulate electrical conductors as supporting components. They consist of insulating bodies that are attached to a base made of wood, concrete or steel with metal supports. The electrical conductors are held on the insulator head with the help of a wire bundle, a wire spiral or a clamp.
  • An oscillating head clamp is to be understood as a clamp which is rotatable on the insulator head about a horizontal axis, in the conductor direction, in order to allow the wind-excited vibrations of the conductor cable to pass through the insulator as freely as possible.
  • An oscillating head clamp has become known, the fastening part of which consists of a solid cast body which is cemented onto the insulator head, with bearing blocks in which the clamping body, which is simultaneously designed as an axis, is rotatably mounted.
  • the design of the fastening part is relatively complex in terms of material and manufacturing process.
  • the invention has for its object to simplify the fastening part of the head clamp, while avoiding the disadvantages mentioned above.
  • the fastening part has brackets arranged on both sides of the insulator head, between which the clamping body is rotatably mounted on an axis.
  • brackets consist of tabs, that the tabs are fastened with threaded screws guided through openings in the insulator head, and that the brackets are bent from a profile material in a U-shape so that the angled ends of one Bracket can be pushed through openings in the insulator head, and that the other bracket can be plugged and screwed with its free ends to the angled ends.
  • the fastening part consists of a few, in one press or. Bending process manufactured individual parts, and can be assembled in a simple manner. The complex cementing of the fastening part on the insulator head is not necessary. Furthermore, separate storage of insulators and terminals is possible.
  • a head clamp 1 which consists of a clamp body 2 with a clamp cover 3 (as a finished product) and a fastening part 4, with which the head clamp 1 is mounted on the insulator head 5 of a support insulator, not shown, in a manner capable of vibration.
  • the fastening part 4 has two cranked tabs 6 made of flat material, which are arranged on both sides of the insulator head 5, and between which the clamping body 2 is rotatably mounted on an axis 7.
  • the head clamp 1 is pre-assembled so that the two tabs 6 with the clamp body 2 through the at both ends by pins 11 secured axis 7 are interconnected.
  • threaded screws 8 are to be inserted through openings 9 in the insulator head 5 and the other tab is to be opposed and fastened with threaded nuts 10.
  • FIGS. 3 and 4 A further embodiment of a fastening part of a head clamp 1 can be seen in FIGS. 3 and 4.
  • the fastening part consists of two from a round profile U-shaped brackets 12, 13, wherein the right-angled leg ends 18 of the bracket 12 are inserted through openings 9 in the insulator head 5, while the other bracket 13 via holes 19 arranged on its leg ends on the leg ends 18 is attached and fastened with threaded nuts 10.
  • a sheet 21 is welded in each case and provided with a bore 22.
  • the clamping body 2 is rotatably mounted with its axis 7.
  • Figures 5 and 6 show as a fastening part of a head clamp a circular clamping bracket 15, which consists of two halves which are screwed together like a flange.
  • a flat material is welded vertically onto the two halves of the clamping bracket 15 as a holder 14, between which the axis 7 of the clamping body 2 is mounted.
  • the clamping bracket 15 is placed in a head groove 26 of the insulator head 5 and tightened by tightening the threaded sleeves 23.
  • the clamping body 2 is mounted between two holders 16 which consist of a flat material and an opening 24 at their lower end have, through which a rope loop 25 is pulled, with which the brackets 16 are attached to the insulator head 5.
