Background
With the development of economy and the increase of railway traffic, the contact line and the carrier cable of an electrified railway constructed in early stage are gradually unable to meet the highest running current carrying and safe operation requirements of an electric locomotive due to the abrasion of the contact line, and the contact line and the carrier cable are required to be replaced on the premise of not affecting the normal operation of the existing power supply system in the overhaul and capacity expansion transformation process of the contact line.
In the existing line carrier wire replacement construction, the carrier wire and the upper and lower construction cannot be completed in the same skylight point due to limited construction conditions and skylight time and high construction difficulty, so that a new carrier wire and a contact wire are separately erected, namely an anchor section contact net is separately replaced in two skylight points.
When the carrier cable at the soft positioning position in the traditional small curve is erected, in order to avoid grinding a V-shaped stay wire or a supporting tube by a new carrier cable, the reverse positioning tube is fixed by an iron wire, then the V-shaped stay wire is loosened, and when the new carrier cable is anchored down, the iron wire is removed and the V-shaped stay wire is restored to the original position when the new carrier cable is poured above the flat wrist arm. However, the traditional construction method for erecting the small curve segment carrier cable is easy to cause deformation of the positioning pipe, is difficult to recover, and takes time and labor for installing and removing the iron wire, loosening and recovering the V-shaped stay wire, so that the integral construction in the skylight point is affected. The small curve section carrier cable is poured above the flat cantilever and fixed, and the carrier cable is close to the carrier cable seat and is easy to be damaged by abrasion caused by the deflection of the cantilever, so that the normal operation of the equipment is affected. Therefore, when the carrier cable is erected and fixed at the small curve, the newly erected carrier cable needs to be supported out, so that abrasion with a V-shaped stay wire or a positioning support is avoided, and abrasion with a carrier cable seat is avoided when the new carrier cable falls down to the position above the wrist arm after falling down the anchor.
