Abstract
A special fixture for dissembling porcelain bottles at head ends of two-connected strings of insulators. The special fixture comprises a front clamp and two screw rods. The middle of each screw rod is fixedly provided with a crank. Two ends of each screw rod are respectively in screwed connection with a connecting sleeve. End portions of the connecting sleeves are provided with hinging through holes. The special fixture is characterized in that the special fixture is further provided with a rider plate clamp; two ends of the rider plate clamp are respectively provided with one hinging hole which is corresponding to the hinging through holes of the connecting sleeves; one end of the ride plate clamp is provided with a recessed groove which extends from an end surface to the middle of the ride plate clamp; and the shape of the bottom wall of the recessed groove is matched with the shape of the outer contour of an object to which the recessed groove is attached. According to the special fixture of the utility model, the hinge joint of hinging shafts of the rider plate clamp and a double-connection plate is utilized; the shape of the bottom wall of the recessed groove is the same with the shape of the outer contour of a contact surface of the double-connection plate; and therefore, firm clamping can be realized. With the special fixture adopted, it is convenient to replace the porcelain bottles at the head ends of the two connected-strings of insulators.
Description
[technical field]
The utility model relates to a kind of enclosed jig that uses in electric power system.
[technical background]
At present, the instrument that the replacing of transmission line bigeminy insulator string porcelain vase is adopted usually is the enclosed jig, and the structure of this enclosed jig comprises preceding card, back card and screw mandrel, and the screw mandrel middle part is provided with the screw mandrel crank.During use, the jig detachable cap is held porcelain vase before and after opening, and front and rear card is snapped on porcelain vase steel clevis and the bowl head, tightens the movable joint nut.Shake the crank of two rhizoid bars, two rhizoid bars are tightened up simultaneously, the porcelain vase of changing until need is lax, takes out the porcelain vase pin porcelain vase is deviate to change.But the enclosed jig of existing this structure is only applicable to the replacing of bigeminy string middle part monolithic insulator porcelain vase, and is then helpless for the replacing of first and last end porcelain vase.Certainly, operating personnel also can select machete card or bent plate card to cooperate the bottle supporting frame to change, but, owing to will be equipped with heavier yoke plate and bottle supporting frame, add work high above the ground, if run into regions with complex terrain such as mountain area again, not only transport, carry inconvenience, and the efficient that wastes time and energy is low, thereby has had a strong impact on the power supply reliability of transmission line.
[summary of the invention]
For solving the problems of the technologies described above, the utility model aims to provide a kind of dismounting bigeminy string head end porcelain vase special mould clamp, rely on this jig can change the insulator porcelain vase of the head end of strain tower duplex string or similar connected mode easily, and have the easy and low advantage of labour intensity of working specification.
For achieving the above object, the utility model has adopted following technical scheme: this dismounting bigeminy string head end porcelain vase special mould clamp, card and two rhizoid bars before comprising; The middle part of described screw mandrel is fixed with a crank, and two ends spin with a branch sleeve respectively; The end of described branch sleeve is provided with hinged through hole, it is characterized in that: also have the integrated circuit board of riding, these two ends of riding integrated circuit board have the corresponding hinge hole of hinged through hole with described branch sleeve respectively; This end of riding integrated circuit board has one and begins the Baltimore groove that extends to the middle part from end face, and the shape of described Baltimore groove bottom land wall and its outer contour shape that will adhere to object are complementary.
During as preferred concrete enforcement, the end of described crank is lever handle link, connects through hexagonal counterbore and external handle.
During as preferred concrete enforcement, the end of described crank is the link of screw-type handle.
Beneficial effect: compared with prior art, the utility model utilizes this Baltimore groove of riding on the integrated circuit board to straddle on bigeminy insulator string iron tower side two yoke plates, cooperate with preceding card through two rhizoid bars, the hinge hole of integrated circuit board end is ridden in dependence, realize and iron tower side two yoke plates, and the branch sleeve integral body of two rhizoid boom ends is hinged, and utilize the Baltimore groove bottom land wall shape identical with two yoke plate contact-making surface outlines to realize firm screens, it is lax until the head end porcelain vase to tighten up the bigeminy insulator string through crank, two two-way screw mandrels and branch sleeve, realizes changing purpose.
[description of drawings]
Fig. 1 is the perspective view of an embodiment of the utility model.
Among the figure: preceding card 1, active card lid 11, hole clipping 12, card arm 13, preceding card hinge hole 14, preceding card hinge hole 141; Screw mandrel 2, crank holder 21, crank 22, branch sleeve 23; Ride integrated circuit board 3, link 31, hinged through hole 32, hinged through hole 321, Baltimore groove 33, bottom land wall 34; Screw mandrel 4, hinge hole 41.
[embodiment]
Referring to Fig. 1.This practicality example is by 1, two two-way screw mandrel 2 of preceding card and ride integrated circuit board 3 formations.The middle part of two two-way screw mandrels 2 arranges crank 22, and crank 22 is fixedly connected on the screw mandrel 2 through crank holder 21.Screw mandrel 2 or 4 two ends and branch sleeve 23 spin, and the end of branch sleeve 23 has hinge hole, this hinge hole with ride the hinged through hole 32 of integrated circuit board 3, preceding card hinge hole 14 is complementary, and realizes hinge-coupled by bearing pin.
During use, the branch sleeve 23 with screw mandrel 2 two ends is hinged on the hinged through hole 32 of riding integrated circuit board 3 earlier, on the preceding card hinge hole 141.Card 1 active card lid 11 before opening again, card 1 is stuck on the steel cap annular groove of the corresponding insulator of bigeminy string before making by hole clipping 12, and makes and ride integrated circuit board 3 and straddle on the outline of iron tower side two yoke plates one side.Then, the right-hand member branch sleeve with screw mandrel 4 is hinged on the preceding card hinge hole 14.The left end branch sleeve of screw mandrel 4, ride integrated circuit board 3 and two yoke plates are then hinged by hinge integral body through hinged through hole 321, hinge hole 41 and bigeminy plate hole (porose on two yoke plates).Because the middle part of two yoke plates is by this integral body jointed shaft location, adding two yoke plates stretches into the outline of riding in integrated circuit board 3 Baltimore grooves 33 and Baltimore groove 33 bottom land walls 34 shapes and is complementary that (this is innovation essence of the present utility model, firmness is very good), therefore, riding integrated circuit board 3 can straddle very securely on this two yoke plate.Then, make two rhizoid bars 2 and 4 two-way tightening up by crank 22, thereby make the porcelain vase in the component blocks lax, to be convenient for changing.
During as preferred concrete enforcement, the end of described crank 22 can be lever handle link, connects handled easily through hexagonal counterbore and external handle.Certainly, the end of crank 22 can also be the link of screw-type handle.
Above-described embodiment only is used for explanation the utility model mentality of designing, and should be as limiting invention thinking of the present utility model, and the simple deformation structure that all have been done under the present utility model thinking inspires all should be considered as falling into protection range of the present utility model.
