Second step, aviation warning ball lifting process: walk around lightning protection cable and insulating cord one end of two ends pendency is provided with two rings, namely insulating cord first ring (25) is enclosed within main self-lock rod lanyard hook, untie self-locking, main self-lock rod lanyard hook embeds in secondary self-locking pike pole groove, after insulating cord first ring and main self-lock rod lanyard hook fix, being hooked in by insulating cord second ring (26) is arranged on the lanyard hook (15) of lower edge, kayser main body centre position, must ensure that in aviation warning ball lifting process, between insulating cord first ring and insulating cord second ring, section insulating cord is in relaxed state, avoid self-locking mechanism due to its deadweight self-locking in advance, insulating cord is drawn through spherical shell gathering sill (23), to ensure the stable posture of aviation warning ball in lifting process, the insulating cord other end passes from inside to outside from removable lid edge lacing hole, and is pulled down by ground staff, aviation is warned the height that ball gives rise to lightning protection cable,
3rd step, along with the raising of lift height, it is interior and continuous close to aviation warning ball centre position that lightning protection cable enters aviation warning ball, spheroid will with lightning protection cable for rotation center rotates under the effect of the downward pulling force of insulating cord and removable cover back-moving spring (3) reset force, when the anglec of rotation is more than 90 degree, spheroid relies on lightning protection cable to slide, and lashed cable hook (5) hooks lightning protection cable;
Lightning protection cable is broken off relations with lanyard hook (15) by insulating cord second ring (26) behind the lanyard hook position that is arranged on kayser main body (33) lower edge, centre position;
Pull on insulating cord, insulating cord first ring drives main self-lock rod lanyard hook (12) to move down, secondary self-lock rod (11) and main self-lock rod (10) are left behind, drive one end interlock of self-locking contiguous block (9), jack-up is locked cable clip sheet (7) by self-locking contiguous block, lock cable clip sheet is locked by lightning protection cable, makes major and minor self-lock rod be in self-locking state simultaneously; Pull on insulating cord, insulating cord first ring departs from from the gap location of main self-lock rod lanyard hook (12) and secondary self-locking pike pole groove (14), then insulating cord is extracted out from removable cover lacing hole (22), warns ball depart from completely with aviation, completes aviation warning ball and hangs fixing.
