The two cross-arm strain insulator events in operation of existing charged for replacement, what mainly adopt is insulation rope sling working system, promptly utilize the insulation rope sling on two cross-arms, to fix, and be connected the replacing of carrying out strain insulator with the stringing device, this kind operational method, following shortcoming is arranged: 1,, wayward and make operating personnel and electrified body can not keep enough combined insulations in the operation process because the insulation rope sling is the soft insulating material, may cause the human body discharge accident; 2, using the insulation rope sling to carry out in the operation process, the insulation rope sling inevitably rubs with equipment such as cross-arm, electric poles, has not only lost the effective insulated lengths of part that insulate and restrict, but also can influence its good electric property and cause potential safety hazard; 3, after using the stringing device to tighten up lead, can't effectively control, make stressed itself and the main line T place of connecing of causing of wire jumper that disconnected taking off taken place easily, produce powerful electric arc, even hurt sb.'s feelings or burning apparatus, be equivalent to the disconnected lead-in wire of on-load the wire jumper of branched line; 4, in the operation process, need two operation personnel to cooperatively interact and finish, change an insulator string activity duration average out to 60 minutes, work efficiency is low, technology also can not get guaranteeing.
The utility model content:
Technical problem to be solved in the utility model is exactly that a kind of single hook-type insulation yoke plate is provided at above deficiency, this yoke plate uses simple, not only guarantee the safe distance of operating personnel and electrified body and staff's personal safety, and wire jumper carried out effective control, improved operating efficiency greatly.
Technical solution adopted in the utility model is:
A kind of single hook-type insulation yoke plate includes the yoke plate main body; One end of yoke plate main body has gib head, has out draw-in groove on the gib head, opens draw-in groove and distally cross-arm angle bar activity clamping; The other end of yoke plate main body has chain joint, and movable sleeve is connected to the wire jumper stay hook on the chain joint; One end of wire jumper stay hook can move in chain joint, and the other end prevents effectively that with firm being fixed in the wire jumper stay hook of strain clamp stressed itself and the main line T place of connecing of causing of wire jumper from disconnected taking off being taken place, and avoids producing powerful electric arc and hurts sb.'s feelings or burning apparatus; The middle part of yoke plate main body is provided with fixed card, and the fixed card active card is connected on the cross-arm.
The yoke plate main body is for vertically having the glass fibre or the non-conductive fiber of other high strength of fiber reinforcement, lamination or mold pressing roll or the epoxy resin composite material of pulling explained hereafter as the load parts, and passed through electric and mechanical type approval test.
Opening draw-in groove is intilted right-angled trapezium shape, and the angle of inclination is 5 °～30 °, is good with 10 °～20 °.
Chain joint is the circulus of high-strength alloy material, satisfies requirement of strength on the one hand, and annular design is convenient on the other hand is connected with other drafting tool.
Have from resetting anti-tripping on the wire jumper stay hook.
Yoke plate main body and yoke plate the main body fixed card of both sides up and down are connected by insulated bolt.
Fixed card is T word shape, and has draw-in groove on it, has corresponding sliding tray on the yoke plate main body, fixed card is slidably connected, to satisfy the problem that fixedly secures at two cross-arms of different in width at the length direction of yoke plate main body.
The beneficial effect that the utility model can reach is:
1, the utility model is simple in structure, but carries with easy to use, not only guarantees the safe distance of operating personnel and electrified body, has guaranteed staff's safety, and wire jumper has been carried out effective control, has improved operating efficiency greatly.
2, the utility model manufacturing cost and use cost is cheap, is easy to produce in batches, and promotion effect is better, not only effectively guarantee operating efficiency, avoided potential safety hazard, and avoided large-scale power failure, reduce the economic loss of enterprise, guaranteed people's production and life.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is that the A of Fig. 1 is to view.
Fig. 3 is that the B of Fig. 1 is to view.
Specific embodiments:
The utility model will be further described below in conjunction with accompanying drawing:
As Fig. 1, Fig. 2, shown in Figure 3, yoke plate main body 3 one ends of this list hook-type insulation yoke plate have gib head 1, and what have the right-angled trapezium shape on the gib head 1 opens draw-in groove 2, and opening draw-in groove 2 is 15 ° for the angle that slopes inwardly, and makes to open draw-in groove 2 and the tight clamping of distally cross-arm angle bar; The other end of yoke plate main body 3 has the annular metal chain joint 7 of high-strength alloy material, and movable sleeve is connected to wire jumper stay hook 8 on the chain joint 7, has on the wire jumper stay hook 8 from resetting anti-tripping 9; One end of wire jumper stay hook 8 can move in chain joint 7, and the other end prevents effectively that with firm being fixed in the wire jumper stay hook 8 of strain clamp stressed itself and the main line T place of connecing of causing of wire jumper from disconnected taking off being taken place, and avoids producing powerful electric arc and hurts sb.'s feelings or burning apparatus; The middle part of yoke plate main body 1 is provided with fixed card 4, and fixed card 4 active card are connected on the cross-arm.Wherein yoke plate main body 1 for the epoxy resin composite material of the glass fibre laminated pulling explained hereafter that vertically has fiber reinforcement as the load parts, and passed through electric and mechanical type approval test, satisfy " GB/T 18037-2008 tools for live working basic fundamental requires and the design guide rule " electric and mechanical requirement relevant to tools for live working; The fixed card 4 of yoke plate main body both sides about in the of 1 is T word shape, and fixed card 4 has draw-in groove, has corresponding sliding tray 6 on the yoke plate main body 1, and fixed card 4 slidably and by insulated bolt 5 connects at the length direction of yoke plate main body.
