Abstract
A special clamp for disassembling a two-string head end ceramic bottle comprises a front clamp and two screws. A rocking handle is fixed in the middles of the screws, two ends of the rocking handle are connected with a connection sleeve respectively in spiral mode, and hinge through holes are arranged on the end portions of the connection sleeve. The special clamp is characterized by further comprising a riding plate clamp. Two ends of the riding plate clamp are respectively provided with a hinge hole corresponding to the hinge through holes of the connection sleeve. A groove extending from the end face to the middle is arranged at one end of the riding plate clamp, and the shape of the bottom wall of the groove is matched with the shape of the outer contour of an object to be adhered. The special clamp utilizes hinge of a hinge shaft of the riding plate clamp and a two-string plate and utilizes the identical shape of the bottom wall of the groove and the outer contour of the contact face of the two-string plate to achieve firm clamping, thereby resolving the problem of replacement of the two-string insulator head end ceramic bottle.
Description
[technical field]
The present invention relates to a kind of closed type fixture that in electric power system, uses.
[technical background]
At present, the instrument that the replacing of transmission line bigeminy insulator string porcelain vase is adopted usually is closed type fixture, and the structure of this closed type fixture comprises front card, rear 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, until the porcelain vase that needs to change relaxes, take out the porcelain vase pin porcelain vase is deviate to change.But the closed type fixture 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 bottle-holding rack to change, but, owing to will be equipped with heavier yoke plate and bottle-holding rack, add work high above the ground, if run into again the regions with complex terrain such as mountain area, 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 present invention aims to provide a kind of dismounting bigeminy string head end porcelain vase special mould clamp, rely on this jig can change easily the insulator porcelain vase of the head end of strain tower duplex string or similar connected mode, and have advantages of that working specification is easy and labour intensity is low.
For achieving the above object, the present invention has adopted following technical scheme: this dismounting bigeminy string head end porcelain vase special mould clamp comprises front card and two rhizoid bars; 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 respectively the corresponding hinge hole of hinged through hole with described branch sleeve; 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 implementation, the end of described crank is lever handle link, connects through hexagonal counterbore and external handle.
During as preferred implementation, the end of described crank is the link of screw-type handle.
Beneficial effect: compared with prior art, the present invention utilizes this Baltimore groove of riding on the integrated circuit board to straddle on bigeminy insulator string steel tower side duplex plate, cooperate with front card through two rhizoid bars, the hinge hole of integrated circuit board end is ridden in dependence, realize and steel tower side duplex plate, and the branch sleeve integral body of two rhizoid boom ends is hinged, and utilize the Baltimore groove bottom land wall shape identical with duplex plate contact-making surface outline to realize firm screens, tighten up the bigeminy insulator string until the head end porcelain vase is lax through crank, two Bidirectional-screws and branch sleeve, realize changing purpose.
[description of drawings]
Fig. 1 is the perspective view of one embodiment of the invention.
Among the figure: front card 1, active card lid 11, hole clipping 12, card arm 13, front card hinge hole 14, front 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 Bidirectional-screw of front card 2 and ride integrated circuit board 3 formations.The middle part of two Bidirectional-screws 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, front 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 first, on the front card hinge hole 141.Open again the active card lid 11 of front card 1, by hole clipping 12 front card 1 is stuck on the steel cap annular groove of the corresponding insulator of bigeminy string, and make and ride integrated circuit board 3 and straddle on the outline of steel tower side duplex plate one side.Then, the right-hand member branch sleeve with screw mandrel 4 is hinged on the front card hinge hole 14.The left end branch sleeve of screw mandrel 4, ride integrated circuit board 3 and duplex plate is then hinged by hinge integral body through hinged through hole 321, hinge hole 41 and bigeminy plate hole (porose on the duplex plate).Because the middle part of duplex plate is by this integral body jointed shaft location, adding duplex plate 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 invention, firmness is very good), therefore, riding integrated circuit board 3 can straddle on this duplex plate very securely.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 implementation, the end of described crank 22 can be lever type hand 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 mentality of designing of the present invention, and should be as limiting invention thinking of the present invention, and the simple deformation structure that all have been done under invention thinking of the present invention inspires all should be considered as falling into protection scope of the present invention.
