Embodiment Construction
[0021] like figure 1 A micro-tension rope pulling method for unmanned aerial vehicles based on sag control is shown, taking two iron towers with a span of less than 500 meters and a span height of not less than 20 meters as an example, including the following steps:
[0022] a. On the UAV 3, use the colored belt 8 to suspend a counterweight, set a pay-off ring 4 on the A iron tower 1 of the two iron towers to be crossed, and coil the wire coiled on the damping pay-off 5 The light and high-strength guide rope 6 is connected to the counterweight 7 of the pillow-shaped sponge body after passing through the pay-off ring 4, and the guide rope 6 is also arranged with identification flags at intervals; wherein, the damping pay-off device 5 is arranged on the A iron tower On the ground of side 1 or on tower A 1, its structure is as follows figure 2 As shown, it includes an inner shaft 55 and an outer shaft 54 connected by a large-diameter bearing, the inner shaft 54 is connected...

The invention discloses a UAV micro-tension leading rope pulling and paying-off method based on sag control. The UAV micro-tension leading rope pulling and paying-off method comprises the steps that: a, a counter weight is suspended on a UAV by using a developing colored ribbon, a paying-off ring is placed on a tower A of two towers to be crossed, a lightweight high-strength leading rope, which is wound on a damping paying-off device, passes through the paying-off ring and is connected the leading rope with the counter weight; b, the UAV takes off and flies to a tower B of the two towers in a manner of keeping the counter weight above the horizontal plane where the paying-off ring is placed, and keeps an included angle a between the developing colored ribbon and the horizontal plane ranging from 45-10 degrees through adjusting tension applied to the leading rope by the damping paying-off device and flight condition of the UAV; c, and the UAV gets close to a connecting line of the two towers after flying over one side of the tower B, so that the leading rope is close to the tower B, and the UAV releases the developing colored ribbon when the leading rope is connected to the tower B, thereby completing the pulling and paying-off.
Description
technical field [0001] The invention relates to the field of high-altitude power cable installation, in particular to a sag control-based micro-tension rope pull-out method for an unmanned aerial vehicle. Background technique [0002] The inventor has previously applied for "aerial cable unwinding tractor and its special lifting tool" and "lifting heavy-duty power cable high-altitude cross-span spreading device", which are used to solve the problems of power and communication line construction, maintenance and emergency repair. Often the problem of needing to cross complex obstacles, both devices require that load-carrying ropes have already been arranged between the towers to be crossed. [0003] For the first crossing problem, the existing technology fixes the guide rope on the drone and pulls it to the target place with a heavy hammer to release it, which overcomes the disadvantages of using a rope-throwing gun, powered parachute or remote control airship in the past; Un...
