Embodiment
The present invention will be further described in detail with reference to the accompanying drawings and detailed description.
As shown in Fig. 1~5, a kind of insulator chain hanging point way to play for time, including electric tower cross bar and be placed on electric tower cross bar
Insulator chain, it is characterised in that it is described between hanging plate and insulator chain provided be at least connected with a section it is scalable and tool
There is the device of resilience.The device can be that flexible rope can also be spring.
The device of resilience can also be that, including upper connecting tube and lower connecting tube, the upper connecting tube is interior provided with scalable
The steel wire rope of extension, the steel wire rope lower end is fixedly connected in lower connecting tube, and the upper connecting tube upper end is hinged with hanging plate,
The lower connecting tube is hinged with insulator chain.
A kind of insulator chain hanging point attachment structure, including electric tower cross bar 10 and the insulator chain that is placed on electric tower cross bar 10
20, the electric lower end of tower cross bar 10 is fixed with hanging plate 110, and one scalable group is passed through between the hanging plate 110 and insulator chain 20
Part 30 is connected, and the scalable component 30 includes being provided with upper connecting tube 310 and lower connecting tube 320, the upper connecting tube 310
The steel wire rope 40 of scalable extension, the lower end of steel wire rope 40 is fixedly connected in lower connecting tube 320, the upper connecting tube 310
