Description
Technical field
The invention belongs to technical field of power systems, a kind of more changing device of insulator is refered in particular to.
Background technology
Transmission line of electricity operation and maintenance service work is to grasp grid operating conditions, the in time weight of discovery and processing equipment defect
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 whole national grid
In core status, therefore the operating maintenance work of extra-high voltage grid is for ensureing extra-high voltage grid or even whole national grid
Safe and stable, reliability service tool is of great significance.It is power transmission lines overhauling and livewire work to replace strain insulator string
Conventional project, and the routine work of transmission line of electricity operating maintenance, 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, 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, the patent of invention of Application No. " 201611025450.1 " discloses a kind of insulator more
Change fixture, including for be replaced left card main body that the connection gold utensil of insulator chain one end fixes, for in insulator chain
The right card main body and be connected between the left card main body and right card main body for described that the steel cap of a certain insulator is fixed
Apply the screw component of pretightning force between left card main body and right card main body；The right card main body, which is formed, can be stuck in insulator steel cap outside
Bayonet.
But the defects of above-mentioned insulator replacement fixture is due to its left card main body and right card agent structure, can not adapt to different rulers
The insulator of very little steel cap for insulator, it is necessary to manufacture corresponding insulator replacement fixture, poor universality, more numerous in operation
It is trivial, also create the waste of resource.
The content of the invention
The object of the present invention is to provide a kind of adaptability is wider, the more firm replacing device for insulator of connection.
The object of the present invention is achieved like this：
A kind of more changing device of insulator, including fastener, the fastener include the steel that mutual cooperation can fix insulator
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
The second opposite arc groove of first arc groove, be rotatably provided with the cell wall of first arc groove and the second arc groove to
Few two claws for being used to fix steel cap.
Insulator in the present invention includes insulator body and the steel cap for being fixed on insulator body front end, the insulator
Recessed card line is provided between main body and insulator steel cap；Longitudinal direction in the present invention is parallel with the central axes direction of steel cap.
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
Title is provided with two mounting grooves, and 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 rear 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 with the pre-and post perforative groove of claw in the middle part of the arc surface.Symmetrically arranged two peaces in first arc groove
Symmetrically arranged two mounting grooves in tankage and the second arc groove, coordinate the claw set in each mounting groove, can make card
Fixation of the part to insulator is more firm, and the medial surface of claw can make claw for the design of arc surface and arc surface upper groove
The different shape and size of the insulator steel cap general with the market can be matched preferably, be conducive to improve this more changing device
