MULTIPLE-STAGE CONTACT WIRE STRAIGHTENING EQUIPMENT FOR A TROLLEY LINE

摘要

The present invention relates to an electric trolley line straightening device which accomplishes straightness of an electric trolley line during an installation process while installing electric trolley lines for a subway or a high-speed railroad in multiple stages. The multi-stage electric trolley line straightening device is characterized in comprising: a primary straightening device which bends the electric trolley line in a direction contrary to an electric trolley line winding direction to calibrate a curvature of the electric trolley line; a secondary straightening device which calibrates tiny uneven portions and curvatures of the electric trolley line; and a stand which supports the primary straightening device and the secondary straightening device. According to the present invention, a calibration efficiency can be increased compared to a conventional straightening device for an installation of an electric trolley line by calibrating remaining curvatures and tiny uneven portions after winding by using an electric trolley line straightening device available at an installation site.
