Fixing belt 2, lower fixing belt 3.
使用该杆塔电缆展放封闭式滑车之前,利用固定软带把滑车固定在杆塔悬挂点位置,打开封门和活动立式滑轮II,利用传递绳提起电缆放入滑车内,电缆放好后封闭封门和立式滑轮II,这时牵引机牵引电缆,顺线路方向以均匀速度进行,使电缆与滑车保持90度,防止刮碰电缆,电缆走动时三个滑轮旋转,滑轮随着电缆旋转,每基杆塔放一个滑车,通过固定软带固定和拆卸,如果多个电缆每基杆塔可以悬挂多个滑车,上下排列进行展放。 Before using the tower cable to deploy the closed tackle, use the fixed soft belt to fix the tackle at the suspension point of the tower, open the sealing door and the movable vertical pulley II, use the transfer rope to lift the cable into the tackle, close the sealing door and Vertical pulley II. At this time, the traction machine pulls the cable, and proceeds at a uniform speed along the line direction, so that the cable and the pulley are kept at 90 degrees to prevent the cable from being scratched. When the cable moves, the three pulleys rotate, and the pulley rotates with the cable. Put a pulley, fix and disassemble through the fixed soft belt, if multiple cables can hang multiple pulleys per base tower, arrange them up and down for deployment.
