Screw type anchor wire clip for load-bearing cable terminal

Abstract

The invention discloses a screw-type anchor wire clip for a load-bearing cable terminal, belonging to the field of an electrified railway contact network and a fastening device. The screw-type anchorwire clip for a load-bearing cable terminal comprises a wire clip body and a tapered wedge arranged in the wire clip body, wherein the wire clip body is a U-shaped barrel with an opening, and is formed by excavating a coaxial circular platform body inside the cylinder, and the large circular cross section of the coaxial circular platform body is flush with one end of the wire clip body; the tapered wedge is in the form of a circular table, and is longitudinally provided with a central hole for placing the load-bearing cable, and the outer side thereof is provided with a spiral groove for placing the load-bearing cable; the taper of the inner wall of the clip body is equal to the taper of the outer wall of the tapered wedge; and the load-bearing cable passes through the thread hole of the wire clip body, the central hole of the tapered wedge and the spiral groove in turn. The screw type anchor wire clip for a load-bearing cable terminal has the advantages of simple and reasonable structure, long service life and increased clamping force with the increase of the tension force of the load-bearing cable.

Description

technical field [0001] The invention mainly relates to the field of electrified railway contact network and fastening device, in particular to a helical anchor clamp at the end of a catenary cable. Background technique [0002] The catenary cable terminal anchorage structure is widely used in electrified railways. The anchorage clamp structure of the catenary cable terminal in the prior art is as follows: there is a taper sleeve with a tapered inner hole, and a wedge is provided in the taper sleeve. During use, the clamping part often breaks or cannot be clamped. That is, the clamping force of the anchor clamps in the prior art is relatively poor, generally far less than the load-bearing strength of the catenary cable, thereby increasing the risk factor. Therefore, it is of certain application value to design an anchor clamp whose clamping capacity is much greater than the strength of the catenary cable. Contents of the invention [0003] The technical problem to be solv...
