Abstract
The invention relates to an apparatus for middle phase crossing in line laying of a helicopter and a line laying method. The apparatus comprises a middle-phase line-laying pulley arranged below a power transmission tower cross arm; and an inlet support, an outlet support, and a line clamp ring are arranged on the cross arm. One segment of guidance steel rope is arranged in a middle-phase pulley of each base tower in a penetrating mode; a stopping block is fixed at an outlet end of the guidance rope and the line clamp ring is arranged at one end, arranged at the inlet support, of the guidance rope for fixation; the outlet end passes through the pulley and goes around the cross bar and then is arranged on the outlet support arranged above the middle-phase cross arm; and a stopping block clamps at the outlet support for fixation. When a helicopter pulls a guidance rope to reach the place above the iron tower, the guidance rope descends by aligning the inlet support and is dismounted manually from a hook; a reserved rope head of an inlet side and a rope head of the inlet support are connected together, wherein the reserved rope is connected with the guidance rope at this time; the worker hooks the other end of the reserved rope of the outlet support on the hook of the helicopter continuously; the helicopter is notified to leave the base tower and pulls the rope to a next base tower. Therefore, the apparatus is suitable for various middle-phase cross arms with different widths and cross sections; and thus the cost is low on the premise of function realization.
Description
Technical field:
The present invention relates to device and line-putting method thereof that a kind of unwrapping wire crosses middle phase, more specifically relate to device and line-putting method thereof that a kind of vertiplane unwrapping wire crosses middle phase.
Background technology:
In the closed steel construction of the middle phase releasing pulley of V-type, wine glass-shaped, cathead electric power pylon below steel tower cross-arm. Spreading guiding rope in this releasing pulley, and then during spreading conducting wire, when not cutting off guide rope, first need the one-level guide rope unfolding a diameter 2-4mm with aircraft, then lead with this one-level guide rope and put second stage 3-5 root guide rope. Guide rope often leads when being put into a base tower, needing manually to climb up high tower moves in the releasing pulley below cross-arm by the guide rope termination on the joint plate being parked in the wait of cross-arm side, pass after coaster until fag end, hanging above the cross-arm of another side after tieback head plate, one-level guide rope just can affect joint plate to draw two grades of guide ropes to next Ji Ta again. This kind of threading is artificial working aloft, not only consuming time, and two grades of guide ropes can only adopt the nylon rope of 10-12mm, also through 2-3 time, nylon rope is drawn the operation that seizing wire is changed to seizing wire traction heavy wire rope, could start to draw wire.
