Description
Technical field
The utility model relates to high-tension bus-bar road technique field, relates in particular to a kind of stringing hook that is used for two string strain insulators.
Background technology
When the two string of transmission line strain insulator 1 carries out stringing on shaft tower now, shown in Fig. 1,2 and 3, the general oil immersion steel wire rope 2 that uses connects two U type links, these two U type links are connected in the yoke plate 11 that two string strain insulators 1 are connected with lead 3, claim on two reserving holes of back yoke plate again, the below staff tightens up oil immersion steel wire rope 2 two string strain insulators 1 is hung on the shaft tower by coaster 4 drop-down oil immersion steel wire ropes 2.The operating personnel insulator string 1 is connected with the shaft tower end finish after, need ride along insulator and climb to the insulator string conductor wire end, U type link and the lead side yoke plate 11 that connects is separated from.
When mounted, two string strain insulators 1 need be utilized wiring or corresponding utensil to fixedly connected with oil immersion steel wire rope 2, if it is fixing improper, situations such as two string strain insulators 1 can bounce back, twist, upset, difficulty when so just having increased stringing greatly, needs use bigger tractive effort excessively two string strain insulators can be connected on the shaft tower; After connection finishes, also need the operating personnel to climb out of to the lead side along two string strain insulators, two U type links that oil immersion steel wire rope 2 is linked to each other with yoke plate and wiring or fixer dismounting, the operating personnel can return on the shaft tower then.So both increased operation intensity, activity duration, and reduced power supply reliability, also the safety to the person, equipment also causes certain threat.
The utility model content
The utility model is at above-mentioned the deficiencies in the prior art, a kind of two string strain insulator stringing hook is provided, can realize need not to use wiring or corresponding utensil fixed insulation substring, two string strain insulators remain exceptionally straight state, also need not use excessive tractive effort excessively that two string strain insulators are connected with shaft tower.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of pair of string strain insulator stringing hooks, and for directly tabular, an end is provided with the joint that flexibly connects with the preceding yoke plate of two string strain insulators, and the other end is provided with through hole.
Preferably, described joint is that straight plate one is distolateral to the groove that extends to form.
Preferably, described joint is a pin-and-hole.
Preferably, described through hole is a pin-and-hole.
Compared with prior art, the advantage that the utlity model has: adopt straight plate to make the stringing hook, an end flexibly connects with the yoke plate (yoke plate before claiming again) of two string strain insulator shaft tower sides, and the other end is provided with the through hole that the oil immersion steel wire rope connects; Like this when using this stringing hook, make things convenient for the operating personnel on the shaft tower that preceding yoke plate and shaft tower are coupled together, need not to use wiring or corresponding utensil fixed insulation substring, two string strain insulators remain exceptionally straight state, also need not use excessive tractive effort excessively that two string strain insulators are connected with shaft tower.The operating personnel also need not climb to the back yoke plate along two string strain insulators two U type links and wiring or fixer are removed, and has improved operating efficiency, power supply reliability so greatly, and operating personnel's safety is also more guaranteed.Reach and reduce operation intensity, minimizing activity duration, improve power supply reliability, guarantee the purpose of operating personnel, device security.

Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
A kind of two string strain insulator stringing hooks as shown in Figure 4, for directly tabular, directly one of plate is distolateral to extending upward formation groove 6, groove 6 is when being connected with yoke plate 11 before two string strain insulators, the side of yoke plate 11 gets final product before only needing groove 6 is hooked on, and, also can very convenient stringing be hooked up down with after shaft tower is fixedlyed connected at two string strain insulators, simple to operate, time saving and energy saving; And be provided with through hole 5 at the other end of straight plate, make things convenient for oil immersion steel wire rope 2 to connect; Operating personnel's tractive oil immersion steel wire rope 2 of below through following extension coaster or towards sky coaster 4, produces pulling force to the stringing hook, thereby by groove 6 two string strain insulators is strained.
Because this stringing hook is to be hooked on the preceding yoke plate 11, utilize two string strain insulators with the lead pull-up, be suspended on the shaft tower then.Two string strain insulators are subjected to tension in operation process, all the time be in exceptionally straight state, the situations such as retraction, distortion, upset in the existing stringing can not occur, reduce wiring or fixer simultaneously, avoid the operating personnel in the process of relevant appliance is removed in outlet, the Personal Risk to be taken place.
Another kind of stringing hook as shown in Figure 5, what adopt is that straight plate one end is made as pin-and-hole 8 and cotter way 7 structures, adopt bearing pin to be connected with the hole on the preceding yoke plate 11 at this end, yoke plate 11 inserts in the cotter ways 7 hole site to pin-and-hole 8 and the preceding yoke plate 11 promptly, thereby reach this stringing hook and preceding yoke plate 11 is flexibly connected.The straight plate other end is provided with the through hole 5 that makes things convenient for oil immersion steel wire rope 2 to connect.
In above-mentioned two embodiment, through hole 5 also can be made as the pin-and-hole structure, and promptly the joint of oil immersion steel wire rope 2 is made as ring-type, can connect fast and separate.
This stringing hook can be realized need not to use wiring or corresponding utensil fixed insulation substring, and two string strain insulators remain exceptionally straight state, also need not use excessive tractive effort excessively that two string strain insulators are connected with shaft tower.The operating personnel also need not climb to the lead side along two string strain insulators two U type links and wiring or fixer are removed, and has improved operating efficiency, power supply reliability so greatly, and operating personnel's safety is also more guaranteed.
No matter this stringing hook can both be guaranteed activity duration, operation intensity and operating personnel's safety.Existing method generally needs 10-15 minute time by beginning to be mounted to end, and also traction method is improper, reasons such as U type suspension bolt is impaired, endure cold winter, weather are incured loss through delay more time because cross for possibility.If it is correct to need only using method behind this stringing of use hook, only just can be with this end-of-job with about 1 minute.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
