Pushable finished steel stranded wire harness

Abstract

The invention discloses a pushable finished steel stranded wire harness, which comprises a plurality of steel stranded wires, mark plates and steel wires, wherein the mark plates pass through the steel stranded wires, the steel stranded wires are bundled up through the steel wires, and a threading head is arranged on the front ends of the steel stranded wires, and is fastened and packed on the front end heads of the steel stranded wires. The pushable finished steel stranded wire harness has the beneficial effects that the pushable finished steel stranded wire harness is suitable to convey finished steel stranded wire harnesses to pass through corrugated pipe channels through a pusher push technology, the threading head is made from plastic products, and the pushable finished steel stranded wire harness is simple in structure, lower than metal products more than double in cost and rapid in construction safety progress. The threading head can be fastened and packed on the front end heads of the steel stranded wires, and the making process of finished steel stranded wire harnesses is simple and convenient. The pushable finished steel stranded wire harness has excellent fixation effect for the steel stranded wires, and prevents a phenomenon that the steel stranded wires get away from the threading head.

Description

Technical field [0001] The invention relates to a finished steel stranded wire harness, in particular to a pushable finished steel stranded wire harness. Background technique [0002] In the construction of bridges and railway foundations, it is necessary to thread multiple steel strands into the prepared corrugated pipe tunnel. In order to overcome the defects of passing through a single steel strand in the corrugated pipe tunnel in turn, the first The multiple steel strands are combed into bundles, and then the multiple strands combed into a whole bundle are threaded into the corrugated pipe channel. The construction process of pulling the whole bunch of steel strands into the corrugated pipe tunnel is: first pass a traction rope through the tunnel, then fix one end of the traction rope to the traction head of the steel strand bundle, and fix the other end to the tractor. Finally, under the traction of the tractor, the traction rope takes the stranded wire bundle through the c...

AI Technical Summary

Problems solved by technology

[0003] The traction head of the above-mentioned prior art is subjected to a large force during the traction process. Therefore, the traction head is all made of high-strength metal, and it is indispensable to be provided with a suspension ring or a ring for fastening the traction rope on the traction head. The traction hook, so the structure of the traction head is complicated; in addition, the traction head must be firmly connected to the entire bundle of steel strands. Once the connection is loose, there will be defects in the traction process that the traction head will be separated from the entire bundle of steel strands, which will delay the construction progress
