Embodiment 1
[0045] Such as Figure 1-11 As shown, a kind of device that the invention provides for the helicopter to pay out the middle phase includes a helicopter 1, a guide wire rope 2 drawn by the helicopter 1, a middle phase pay-off block 7 arranged under the cross arm of the power transmission tower and a threading wire rope. Pass the reserved guide rope 8 of the intermediate phase pay-off block 7; the two ends of the reserved guide rope 8 are respectively placed on the bracket and the fixed ring on the cross arm.
[0046] The support includes an incoming line support 3 and an outgoing line support 5; the fixed ring is a clamping ring 4; the incoming line end of the reserved guide rope 8 is arranged on the clamping ring 4; the reserved The outlet end of the guide rope 8 is stuck on the outlet bracket 5 through a blocking block.
[0047] The incoming line bracket 3 includes a V-shaped outrigger guide rod and a support; the support is two struts connected by an upper hanging chain 14 ...

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: [0001] The invention relates to a device and a method for paying out wires through the middle phase, and more particularly to a device for paying out wires through the middle phase of a helicopter and a method for paying out the wires. Background technique: [0002] The medium-phase pay-off block of V-shaped, wine glass-shaped and cat-head-shaped transmission towers is inside the closed steel structure under the cross-arm of the tower. When laying out the guide rope in this pay-off block, and then laying out the wire, under the condition of not cutting the guide rope, it is first necessary to use the aircraft to lay out a first-level guide rope with a diameter of 2-4mm, and then use this The first-level guide rope pulls and releases the second-level 3-5 guide ropes. When the guide rope is pulled into a base tower, it is necessary to manually climb the tower and move the end of the guide rope on the joint plate waiting on the side of the cross arm to the pay...
