Design and Experimental Research of Rope Missle

Abstract

The UAV (unmanned aerial vehicle) unfolding guide rope is the construction process adopted in the tension stringing of overhead power transmission line. At present, due to the limit of UAV control precision, the function of threading the guide rope into the paying-off sheave groove directly cannot be realized, and we can only unfold the guide rope of UAV to the cross arm of iron tower, and then, make the operation personnel at height transfer the guide rope into the steel wire groove of paying-off sheave. Therefore, the construction efficiency of this process is relatively, and there is operation at height, with a certain safety risk. In this project, it is planned to develop a launching device carried by UAV, and this device uses the compressed carbon dioxide (CO2) which is relatively safe as power source, which realizes the instantaneous release of compressed air through electromechanical servo control, and then generate the power which promotes the “rope missle” to fly. The tail of “rope missle” is connected with guide rope, and when it flies forward, the traction guide rope will move forward synchronously. After the “rope missle” threads into the sheave, the compressed air will be released completely, and then, the “rope missle” will transfer into the motion of a free falling body, thus further driving the falling of guide rope, so as to realize the function of “rope missle” tracts the guide rope to realize threading into the paying-off sheave.
