Abstract

The present invention discloses a wire stranding roller and a new method for the same, in a LP insulator being mounted at a cross arm of pin long column and insulating and supporting a high voltage wire, which drastically improves workability and greatly reduces construction cost because the location of a wire don't need to be changed after the stranding and wire pulling, which is easy to work with and is very effective in reducing labor cost and preventing a safety accident because it can easily perform wiring and removing works no matter how large the weight of the wires would be, which is capable of precisely adjusting a dip (degree in which the wire hangs down) because the wire are placed on an insulator, which is to be mounted, during a wire pulling work and also which can solve the problem of securing a work space when carrying out the work applying and uninterruptible method by forming a open-and-shut roller capable of wire insertion and a wire stranding roller consisting of an insulator coupling opening and directly coupling them on the upper surface of the LP insulator.

Dependent claims

A wire stranding roller for a LP insulator, comprising:

an upper supporting unit (10) having a front supporting bracket (11), a rear supporting bracket (11′), a cross beam (15) transversely fixed between said front and rear supporting brackets (11, 11′), an upper roller (12) axially and rotationally mounted underneath said cross beam (15) and a handle (13) fixed on top of said cross beam (15),
a pair of left and right vertical supporting units (20), each vertical supporting unit (20) having a vertical rear bracket (22), and a vertical rear roller (21) axially and rotationally mounted on said vertical rear bracket (22),
an insulator coupling unit (30) having a pair of left and right base frames (33), each base frame (33) formed integrally and perpendicular to said vertical rear bracket (22), a pair of symmetrically split half insulator pads (31) with semi-circular center cut outs, each split half insulator pad (31) installed inside of each base frame (33), a rear hinge (34) for hinging said left and right base frames (33), and a screw-type clamp (32) for clamping said left and right base frames (33), and
a pair of left and right open-and-shut units (40), each open-and-shut unit (40) having a roller supporting beam (41) axially and rotationally hinged inside said base frame (33), a base roller (43) axially and rotationally mounted inside said roller supporting beam (41), and a front roller (42) axially and rotationally mounted perpendicular to said roller supporting beam (41), so that said left and right open-and-shut units (40) are bilaterally rotated with respect to their axis (45) of said roller supporting beams (41) for latching or unlatching to said front supporting bracket (11).
