Embodiment
As shown in Figure 1, the vertical single hook jig of the utility model live line working, has arm 3 and the hook portion 4 of Integral design, arm 3 is provided with connecting hole 5, and during use, insulation pull-rod is direct and connecting hole 5 is fixing, jig is placed below side of wire, upwards mention jig, make wire slip into hook portion 4.
Single hook jig of the present utility model uses carbon fiber sheet to make, and is the structural representation of carbon fiber sheet used as shown in Figure 7, adopts the sandwich construction of vertical, horizontal intertexture carbon cloth 1 interval two-way intertexture carbon fiber wire layer 2.
As shown in Figure 2, use carbon cloth that longitudinal carbon fiber becomes with horizontal carbon fiber knit as base material, can according to the fabric width of carbon cloth needed for the utility model product requirement determination sheet material and the number of plies.
It is carbon fiber unidirectional cloth shown in Fig. 3, its vertical and horizontal of carbon fiber unidirectional cloth have carbon fiber, but a direction (normally longitudinally) has a large amount of roving, also has a direction to only have a small amount of spun yarn, play fixation, carbon cloth can not be scattered.The intensity of monoblock carbon cloth, all concentrates on that direction of roving, its intensity, and it doesn't matter with self grammes per square metre, only relevant with carbon filament.And the two-way cloth of vertical and horizontal intertexture carbon fiber, its vertical and horizontal have a large amount of rovings, and the Impact direction of such cloth has two, feature is that intertwined point is many, quality is strong, surfacing, and resistance to wear is good, and its comprehensively stressed performance obviously will be better than unidirectional lamination.
The two-way cloth of vertical and horizontal intertexture carbon fiber adopts traditional woven plain weave cloth method, and namely longitudinal carbon fiber and horizontal carbon fiber interweave in rule one on the other.Longitudinally, horizontal carbon fiber every a carbon fiber just in decussation, as shown in Figure 4, longitudinal carbon fiber is 1,3,5,7 upper, 2,4,6,8 under, horizontal carbon fiber is 1,3,5,7 upper, 2,4,6,8 under.
Cross braiding (i.e. two-way intertexture) is carried out with carbon fiber wire between the interlayer of the two-way cloth of adjacent carbon fiber.。Although enhance horizontal by force intensity in length and breadth to two-way carbon cloth because adopt, have lost longitudinal by force intensity also.The bidirectional crossed carbon fiber wire layer in increase left and right is the longitudinal stress intensity in order to cover the loss, and each carbon fiber wire layer intertexture angle can be the same or different, and the intertexture angle of preferred carbon fiber wire is 45 °.
Fig. 5 is preparation technology's FB(flow block) of the utility model carbon fiber sheet, Fig. 6 is carbon fiber board fabrication processing schematic diagram, as shown in Figure 5 and Figure 6, first be the preparation of carbon fibre cloth layer, adopt traditional woven plain weave cloth method, longitudinal carbon fiber and horizontal carbon fiber interweave in rule one on the other; Carbon fiber wire layer adopts and interweaves to two-phase one on the other; By the carbon fibre cloth layer of acquisition and carbon fiber wire layer epoxy resin-impregnated glue; With positioner by the carbon fibre cloth layer layering after epoxy resin-impregnated glue, the carbon fiber wire layer after epoxy resin-impregnated glue is positioned between the interlayer of carbon fibre cloth layer; The pressurization of mould constant temperature, the rear demoulding of cooling is put into after the sheet material of acquisition is put into preheating cabinet preheating.
After epoxy resin-impregnated cementing agent, adopt the pultrusion thermosetting one-shot forming technique of advanced technology, the air gap in finished product can be got rid of to greatest extent, ensure that the stability of sandwich construction.
