Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, the utility model execution mode is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of porcelain rod insulator that the utility model provides is changed instrument, comprising: preceding card 1, back card 2 and take-up system 3, and described take-up system 3 two ends link with preceding card 1 and back card 2 respectively, also comprise hanging system 4, this hanging system 4 links to each other with back card 2 with preceding card 1.Described hanging system 4 comprises two cover tripod assembly 41 and two coasters 42, described two cover tripod assemblies 41 are separately fixed on preceding card 1 and the back card 2, described two coasters 42 are hung on the two cover tripod assemblies 41, the hanging system 4 that such two cover tripod assemblies 41 and two coasters 42 are formed provides two suspension centres, can be by steel cable with porcelain rod insulator hanging to desired location, solved because porcelain rod insulator weight is bigger, when causing changing the porcelain rod insulator, need the whole piece transmission line is had a power failure, by seven porcelain rod insulators are put simultaneously to ground, thereby change the problem (referring to Fig. 2) of the work of single insulator.
As shown in Figure 3, the utility model also comprises connecting rod 43, and these connecting rod 43 two ends link to each other with two cover tripod assemblies 41 respectively, and after two cover tripod assemblies 41 connected by this connecting rod 43, intensity was higher, thereby more stable suspension centre (referring to Fig. 4) is provided.
As shown in Figure 1, the utility model also comprises hanging hook assembly 5, two hanging hook assembly 5 one ends link to each other with back card 2 with preceding card 1 respectively, the hook formation 51 of the other end for matching with porcelain rod insulator groove, when changing insulator like this, the hook formation end of this hanging hook assembly catches on the parallel porcelain rod insulator groove of side, can keep the balance (referring to Fig. 2) of this replacing instrument effectively.Certainly, can be during use only with a hanging hook assembly 5 or more hanging hook assemblies 5.
As shown in Figure 5, the middle part of above-mentioned described hanging hook assembly 5 is telescopic screw structure 52, can regulate the length of hanging hook assembly 5 like this according to actual conditions, to guarantee to keep effectively the balance of this replacing instrument.
