Definitions

  • the invention relates to a device for connecting a first catenary component, which has an axial end part, with at least one second catenary component.
  • z. B. insulators to be connected to other overhead line components.
  • These other overhead line components include z. As pipes (boom pipes, tip tubes), hollow sections or rods.
  • these catenary components generally have to be adapted to each other accordingly. This adaptation takes place via corresponding structural changes in at least one of the overhead line components to be connected to one another, preferably in the region of their connecting pieces.
  • this is technically complicated and requires an expensive storage of appropriate overhead line components.
  • the DE-GM 71 15 471 describes a hanger clamp with two retractable clamp halves through which both a support rope and a grooved guidewire can be held.
  • Each clamp half has at its one end both a half-shell-shaped channel for receiving a support cable and a cutting edge for clamping a contact wire.
  • a recess is arranged in each case. In these recesses, the drawn over a thimble and thus bent to an eyelet end of a hanger rope is inserted, which serves both to hold the support cable and for holding the contact wire.
  • a boom known as a base for a catenary.
  • the boom comprises an obliquely arranged boom tube which is connected via a pin-shaped end piece of its end fitting with the insulating body of a plastic composite insulator.
  • the end fitting sits in this case directly on the insulator or on its shell or shield shell.
  • a connection between a pin-shaped end piece and a yoke is made, which is attached to a pivot boom joint via a bolt.
  • Object of the present invention is to simplify the connection of two overhead line components assembly technology.
  • the device according to the invention for connecting a first catenary component, which has an axial end part, with at least one second catenary component comprises two half-shell-shaped adapter parts which at least frictionally enclose the axial end part of the first catenary component in the mounted state, wherein both adapter parts at least frictionally connectable to the second catenary component are.
  • the device according to the invention not only leads to a reduced number of components to be stored, but moreover enables a quick and cost-effective installation of the overhead line components to be connected to one another, since expensive screw connections can generally be dispensed with.
  • the device according to claim 1 makes it possible profiles of all kinds, such. As rectangular / square hollow sections or round tubes to connect by choosing the appropriate adapter parts together.
  • two adapter parts are referred to, which are formed in a half-shell-shaped.
  • the two adapter parts 1 and 2 enclose in the mounted state, an axial end part 3 of a first catenary component at least non-positively.
  • the first overhead line component 4 shown in FIG. 1 is an insulator (plastic insulator).
  • the termination part 3 of the insulator 4 has a round cross-section, which (initially viewed in the axial direction of the axial end part 3) is initially constant, then reduced and then enlarged again.
  • the axial end part 3 of the insulator 4 is in the illustrated embodiment not only frictionally, but also positively enclosed by the two adapter parts 1 and 2.
  • the two adapter parts 1 and 2 are adapted for this purpose in their mutually facing formations corresponding to the axially varying cross-section of the axial end part 3.
  • Both adapter parts 1 and 2 are further connected at least non-positively to a second overhead line component 5.
  • the second overhead line component 5 is a tube (hollow profile). Such tubes are z. As a boom pipes or tip tubes part of boom structures.
  • the tube 5 is in the embodiment of FIG 1 not only frictionally, but also positively connected to the two adapter parts 1 and 2.
  • the two adapter parts 1 and 2 are placed on the axial end part 3 of the insulator 4 such that the adapter parts 1 and 2 enclose the axial end part 3 in a form-fitting manner. Subsequently, the axial end part 3 is inserted with the two adjacent adapter parts 1 and 2 in the tube 5. The introduction of the axial end part 3 is limited by a collar 6 and 7, which is arranged on the two adapter parts 1 and 2.
  • connection After insertion of the axial end portion 3 in the tube 5 and after pushing the tube 5 on the axial end part 3, the connection is secured by a dowel pin 8.
  • the adapter parts 1 and 2 and the tube 5 have for this purpose a common bore into which the clamping pin 8 can be inserted.
  • the tube 5 can be shrunk onto the two adapter parts 1 and 2.
  • the tube 5 with the two adapter parts 1 and 2 are also pressed.
  • the outer peripheral surface of the adapter parts 1 and 2 must have a corrugation.
  • the two half-shell-shaped adapter parts are denoted by 11 and 12.
  • the two adapter parts 11 and 12 are in turn - as already described in FIG 1 - positively connected to the axial end part 3 of the insulator 4.
  • the free end of the adapter parts 11 and 12 form in the assembled state a trained as a fork connection connecting element 13.
  • the two adapter parts 11 and 12 are enclosed in the assembled state by a slide-sleeve-shaped retaining element 14 ,
  • the sleeve-shaped holding element 14 has a bore which corresponds to the common bore of the two adapter parts 11 and 12 and in which a clamping pin 15 can be inserted.
  • the two adapter parts 11 and 12 and the sleeve-shaped retaining element 14 are secured.
  • the sleeve-shaped support member 14 with the two adapter parts 11 and 12 are also pressed.
  • the axial end part 3 (as well as in the embodiments of FIG 1 and 2) in turn enclosed by two adapter parts 21 and 22 form-fitting manner.
  • the free ends of the two adapter parts 21 and 22 form a connection element 23 designed as an eye connection.
  • the two adapter parts 21 and 22 are enclosed in the mounted state by a push-on sleeve-shaped holding element 24.
  • the sleeve-shaped holding element 24 has a bore which corresponds to the common bore of the two adapter parts 21 and 22 and in which a clamping pin 25 can be inserted.
  • FIG 3 One of the embodiment shown in FIG 3 similar device is from the EP-A-0 066 262 known, although right there is not explicitly mentioned a use in overhead line construction.
  • the invention is not limited to the embodiment shown in FIG. Rather, different overhead line components can be connected to one another in a simple manner with the device according to the invention.
