(2) by the safety rope winding axis of rolling, (axis of rolling can pass through the cunning on both sides to the present invention when being subject to certain power
Rail axis slides), when rope is subject to downward pulling force, all sliding axles are moved in the following, locking safety rope (downward pulling force
More big roller can more lock safety rope), further improve conducting wire fall arrest effect.
Brief description of the drawings
Fig. 1 is the structure diagram of present pre-ferred embodiments；
Fig. 2 is the A-A direction views of Fig. 1；
Fig. 3 is the structure diagram for playing pin assembly.
Embodiment
Referring to Fig. 1 and Fig. 2, the conducting wire falling proof device structure of present pre-ferred embodiments includes flap seat, safety rope 9 and leads
Line hook 8.Wire hook 8 is used for support and fixes conducting wire 11；Flap seat passes through mounting structure and the cross-arm positioned at the top of conducting wire 11
10 fix；Through or around flap seat rear haulage wire hook 8 is connect, which is denoted as suspended end 92 for one end of safety rope 9；Safety rope 9
The other end is as fixing end 91, for keeping or adjusting the suspension height of conducting wire 11.
Mounting structure includes cross-arm hook 1, connector 2 and hanging stick 3；Cross-arm links up with 1 one end and is fixed on the top of conducting wire 11
Cross-arm 10 on, 2 one end of connector and cross-arm hook 1 is flexibly connected, and connector 2 can arbitrarily be revolved around connection end point in the horizontal plane
Turn, personnel convenient to overhaul adjust the installation direction of conducting wire falling proof device；The other end of connector 2 passes through spiral shell with 3 one end of hanging stick
Bolt is fixedly connected, and the other end and the flap seat riveting of hanging stick 3 are fixed, so as to fulfill three sections of cross-arm hook 1, connector 2 and hanging stick 3
Formula connects so that there are certain rotary oscillation space between three, improves the operation free degree of service personnel.
Flap seat includes a square frame and multiple axis of rolling 5 laterally set；Square frame includes two horizontal hanger rods 4
With two longitudinal sunpenders 7；The axis of rolling 5 is between two horizontal hanger rods 4, two longitudinal directions of 5 both ends of the axis of rolling and square frame
Sunpender 7 is flexibly connected.5 stage casing of the axis of rolling is provided with roller 6, and the axis of rolling 5 is aluminum alloy material, and the roller 6 is nylon material,
It is light-weight high-strength material.
Safety rope 9 includes fixing end 91 and suspended end 92, and suspended end 92 sequentially passes through the two neighboring axis of rolling from top to bottom
Between and the axis of rolling and horizontal hanger rod between be connected again with wire hook 8 behind the gap that is formed, safety rope 9 in it is wavy
Shuttle between the axis of rolling 5.Wire hook 8 is used to fix conducting wire.The fixing end 91 of safety rope can be fixed on the horizontal stroke above conducting wire
In load or it is fixed on ground, can also be drawn by the support staff on ground.
Referring to Fig. 3, the axis of rolling 5 is provided at both ends with bullet pin assembly, is provided with two longitudinal sunpenders 7 of square frame more
A groove 71 with playing pin assembly mating reaction.Play pin assembly to be located in the lateral mounting hole of the axis of rolling, playing pin assembly includes spiral shell
