The beneficial effects of the utility model are in that:
(1) this utility model is by the mating reaction of safety rope with flap seat, it is possible to keeps or regulates the suspension height of wire, play the effect preventing wire accidental falling, improve processing safety and the job success ratio of maintainer.
(2) this utility model is wound around the axis of rolling by safety rope (axis of rolling is when being subject to certain power, can be slided by the slide rail axle on both sides), when rope is subject to downward pulling force, all of sliding axle moves to following, locking safety rope (downward pulling force more big roller more can locked safety rope), improves wire fall arrest effect further.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model preferred embodiment；
Fig. 2 is the A-A direction view of Fig. 1；
Fig. 3 is the structural representation playing pin assembly.
Detailed description of the invention
Referring to Fig. 1 and Fig. 2, the wire falling proof device structure of this utility model preferred embodiment includes flap seat, safety rope 9 and wire hook 8.Wire hook 8 is for the fixing wire 11 of support；Flap seat is fixed with the cross-arm 10 being positioned at above wire 11 by mounting structure；One end of safety rope 9 is through or around connecing flap seat rear haulage wire hook 8, and this end is designated as suspended end 92；The other end of safety rope 9 is as fixing end 91, for keeping or regulate the suspension height of wire 11.
Mounting structure includes cross-arm hook 1, connector 2 and hanging stick 3；Cross-arm is linked up with 1 one end and is fixed on the cross-arm 10 above wire 11, and connector 2 one end is linked up with 1 with cross-arm and is flexibly connected, and connector 2 arbitrarily can rotate around connection end point in horizontal plane, facilitates maintainer to adjust the installation direction of wire falling proof device；The other end of connector 2 and hanging stick 3 one end are bolted to connection, the other end of hanging stick 3 is fixing with flap seat riveted joint, thus the syllogic realizing cross-arm hook 1, connector 2 and hanging stick 3 connects so that there is certain rotary oscillation space between three, improve the operation degree of freedom of maintainer.
Flap seat includes the axis of rolling 5 of a quadra and multiple horizontally set；Quadra includes two horizontal hanger rods 4 and two longitudinal suspension rods 7；The axis of rolling 5 is between two horizontal hanger rods 4, and the axis of rolling 5 two ends are flexibly connected with the two of quadra longitudinal suspension rods 7.The axis of rolling 5 stage casing is provided with roller 6, and the axis of rolling 5 is aluminum alloy material, and described roller 6 is nylon material, is light-weight high-strength material.
Safety rope 9 includes fixing end 91 and suspended end 92, suspended end 92 is connected with wire hook 8 after sequentially passing through the space formed between adjacent two axis of rolling and between the axis of rolling with horizontal hanger rod from top to bottom again, and safety rope 9 shuttles back and forth between the axis of rolling 5 in wavy.Wire hook 8 is used for fixing wire.The fixing end 91 of safety rope can be fixed on the cross-arm above wire or be fixed on ground, it is also possible to drawn by the paraprofessional personnel on ground.
Referring to Fig. 3, the two ends of the axis of rolling 5 are provided with bullet pin assembly, and two longitudinal suspension rods 7 of quadra are provided with groove 71 that is multiple and that play pin assembly mating reaction.Play pin assembly and be arranged in the transversely mounted hole of the axis of rolling, play pin assembly and include screw 51, spring 52 and steel ball 53；Screw 51 is installed on the axis of rolling, spring 52 between screw 51 and steel ball 53, groove 71 mating reaction that steel ball 53 and longitudinal suspension rod 7 are arranged.When wire tenesmus risk described previously herein occurs, downward pulling force strains the axis of rolling 5 on anti-fall device and roller 6 by safety rope 9, three rollers 6 are quickly retracted to together, (safety rope 9 presses on the axis of rolling 5 by roller 6 to reach the purpose of locking safety rope, the axis of rolling 5 pressurized backs down steel ball 53, downward sliding, and locked safety rope 9), play the effect stoping the tenesmus of wire moment, thus avoiding accidents.This structure ensures in wire drop event, locking stroke is shorter, and be quick on the draw, avoid maintainer to have to again to tighten up the tightener displacement porcelain vase tension force such as (tightener parts do not lose efficacy when) and (do not replace tension force, porcelain vase cannot be changed), both avoided the accident of work high above the ground and repeated acting, having also mitigated the working strength that the staff of safety rope is drawn on ground simultaneously.
