Description

A kind of more changing device of insulator

Technical field

The utility model belongs to technical field of power systems, refers in particular to a kind of more changing device of insulator.

Background technology

Transmission line of electricity operation and maintenance service work be grasp grid operating conditions, in time find and processing equipment defect weight Means are wanted, are also to ensure that the element task of line security stable operation.Since extra-high voltage grid is in the operation of entire national grid In core status, therefore the operating maintenance work of extra-high voltage grid is for ensureing extra-high voltage grid or even entire national grid Safe and stable, reliability service has a very important significance.It is power transmission lines overhauling and livewire work to replace strain insulator string Conventional project and transmission line of electricity operating maintenance routine work, the left and right card body of the fixture of existing replacing insulator string It is typically only capable to fix in the connection gold utensil (such as yoke plate) at insulator chain both ends, it can only be to whole insulation using this replacement fixture Substring is replaced, and can not only replace a certain section of insulator in insulator chain, and at present to insulator chain into replacement When, it usually needs some segment of insulator chain is replaced.

To solve the above-mentioned problems, application No. is the patents of invention of " 201611025450.1 " to disclose a kind of insulator more Change fixture, include for the fixed left card main body of connection gold utensil for being replaced insulator chain one end, for in insulator chain It the fixed right card main body of steel cap of a certain insulator and is connected between the left card main body and right card main body for described Apply the screw component of pretightning force between left card main body and right card main body；The right card main body formation can be stuck in insulator steel cap outside Bayonet.

But above-mentioned insulator replacement fixture can not adapt to different rulers due to the defect of its left card main body and right card agent structure The insulator of very little steel cap needs to manufacture corresponding insulator replacement fixture for insulator, poor universality, more numerous in operation It is trivial, also create the waste of resource.

Invention content

The purpose of this utility model is to provide that a kind of adaptability is wider, the more firm replacing device for insulator of connection.

What the purpose of this utility model was realized in：

A kind of more changing device of insulator, including fastener, the fastener include cooperating that the steel of insulator can be fixed The card body and Ka Gai of cap, it is characterised in that：Be vertically arranged with the first arc groove on the card body, the card cover be provided with Rotatably be provided on the cell wall of the second opposite arc groove of first arc groove, first arc groove and the second arc groove to Few two claws for fixing steel cap.

Insulator in the utility model includes insulator body and is fixed on the steel cap of insulator body front end, described exhausted Recessed card line is provided between edge main body and insulator steel cap；The central axes direction of longitudinal direction and steel cap in the utility model It is parallel.

It is right on the cell wall of first arc groove and the second arc groove in a kind of more changing device of above-mentioned insulator Claim setting there are two mounting groove, longitudinally disposed axis pin passes through the outer end of claw, and the both ends difference of axis pin in mounting groove It is connected with the front and back cell wall of mounting groove, the inner end of claw is stretched out from the opening of mounting groove；The medial surface of claw is arc surface, It is vertically arranged in the middle part of the arc surface by the pre-and post perforative groove of claw.Symmetrically arranged two peaces in first arc groove Symmetrically arranged two mounting grooves in tankage and the second arc groove coordinate the claw being arranged in each mounting groove, can make card Part is more secured to the fixation of insulator, and the medial surface of claw can make claw for the design of arc surface and arc surface upper groove It can preferably be matched with the different shape of general insulator steel cap in the market and size, be conducive to improve this more changing device Adaptability.

In a kind of more changing device of above-mentioned insulator, it is both provided on the card body at left and right sides of first arc groove Bolt, the upper end of each bolt both pass through card and cover corresponding through-hole and Ka Gai and card body are connected by the nut of cooperation, often The lower end of a bolt forms longitudinal tubular junction, is disposed longitudinally on the shaft at left and right sides of the first arc groove and passes through pipe The both ends of shape interconnecting piece and shaft are connected with card body.The outside of a through-hole in the card lid has opening, corresponding spiral shell Bolt can be turned out and is detached from Ka Gai around the shaft.Card body and Ka Gai can in such a way that rotatable bolt is detachably fixed So that as long as this more changing device controls the stroke of bolt top nut for various sizes of insulator steel cap, in the mistake that nut is tightened Claw can rotate fine tuning self-view around axis pin automatically in journey, keep the medial surface of claw and insulator steel cap more docile, With well adapting to property, and the connection of fastener and insulator can be made more secured, be conducive to improve this more changing device work The stability of work and safety.Further, there is opening, corresponding bolt can rotate axial direction in the outside of one of through-hole Outer rotation and the handling of insulator can be completed in the case where making Ka Gai and card body is not completely separated from the Ka Gai designs being detached from, Make that the operation is more convenient, is conducive to the working efficiency for improving this more changing device.

In a kind of more changing device of above-mentioned insulator, the fastener includes preceding fastener and rear fastener, the preceding fastener Connected by two telescopic leading screws with rear fastener, wherein the rear and front end of a leading screw respectively with the left part of preceding fastener and The left part of fastener is connected afterwards, and the rear and front end of another leading screw is solid with the right part of preceding fastener and the right part of rear fastener respectively Even.Claw rear end after described on fastener is provided with the hook for the card line that can extend into insulator, each card on rear fastener The rear end of pawl is respectively provided with there are two hook, and two hooks take shape in the left and right sides of claw rear end, and each hook protrudes from card The medial surface of pawl and with claw be integrally formed；The claw rear end of the preceding fastener is longitudinally spaced to be provided with more for increasing Add the horizontal stripe of frictional force.Position when preceding fastener and rear fastener in this more changing device are according to from replacement insulator and The difference of effect has special claw structure, wherein the claw being clamped on the preceding fastener of insulator front end is because of its clamping Suffered tensile force is also forward on insulator, therefore only need to be arranged several in the rear end of the claw medial surface of preceding fastener Horizontal stripe can make the clamping of the steel cap of claw and insulator more secured, avoid skidding for increasing frictional force；And it is clamped Claw on the rear fastener of insulator front end because tensile force suffered on the insulator of its clamping backward, therefore in rear card The rear end of the medial surface of the claw of part is provided with two hooks, and being stretched into the card line of insulator by hook enables claw will be exhausted Edge is caught on, and is enable rear fastener that insulator to be clamped more secured, is avoided insulator from being slipped from rear fastener, be conducive to carry The stability of this high more changing device and safety.
