Abstract
The embodiment of the utility model provides a clamp, which aims to solve the problem that a first insulator plate on a lead side of an insulator string has only one insulator plate adjacent to the first insulator plate so as to cause absence of fixing points on a front clamping piece or a rear clamping piece of an existing clamp and incapability of replacing the first insulator plate on the lead side of the insulator string. The clamp includes a closed clamping end, a labor-saving screw rod and a hardware clamping end, wherein the closed clamping end and the hardware clamping end are connected through the labor-saving screw rod, a mounting for fixedly connecting hardware is arranged at the hardware clamping end, and the closed clamping end is used for being fixedly connected with an iron cap of an insulator. Therefore, though the first insulator plate on the lead side of an insulator string has only one insulator plate adjacent to the first insulator plate, the clamp can utilize the hardware clamping end to be fixed with a piece of connecting hardware, the problem of absence of fixing points at the hardware clamping end can be avoided, and further replacement of the first insulator plate on the lead side of the insulator string can be realized.
Description
Technical field
The utility model relates to electric power apparatus examination and maintenance technology field, particularly relates to a kind of jig.
Background technology
In electric power system, insulator string mainly is made up of multi-disc porcelain or glass insulator.Deterioration, breakage take place in porcelain or glass insulator easily, particularly in the strain tower insulator string, because the more and long-term stressed operation of insulator, its degradation phenomena is serious, therefore want in time the insulator of deterioration to be changed processing, the insulator that is about to deterioration in time is replaced with good insulation performance.
The common methods of changing insulator is for using jig.Jig commonly used is generally the enclosed jig that comprises preceding card, back card and laborsaving screw mandrel.When changing strain insulator, the chapeau de fer of two insulators that the preceding card of enclosed jig is adjacent with the insulator of needs replacing respectively with the back card is fixedlyed connected, replace the insulator of needs replacing stressed by tightening up laborsaving screw mandrel, make the insulator that needs to change relax, replace with new insulator thereby can take off the insulator that needs to change.After replacing with new insulator, loosen the laborsaving screw mandrel of enclosed jig, make new insulator stressed, insulator string will be returned to original position.
By research to prior art, the inventor finds: all need to be separately fixed on the chapeau de fer of two insulators adjacent with the insulator of needs replacing owing to have the preceding card and the back card of enclosed jig now, and first insulator of insulator string lead side has only the adjacent with it insulator of a slice, this makes the preceding card of enclosed jig or back block no fixing point, thereby can't change first insulator of insulator string lead side.
The utility model content
For solving the problems of the technologies described above, the utility model embodiment provides a kind of jig, solving preceding card or the no fixing point of back card that has only the existing jig that the adjacent with it insulator of a slice causes because of first insulator of insulator string lead side, and then the problem that can't change first insulator of insulator string lead side.
Its technical scheme is as follows:
A kind of jig comprises: closed fixture end, laborsaving screw mandrel and gold utensil card end;
Wherein, described closed fixture end is connected by described laborsaving screw mandrel with described gold utensil card end;
Described gold utensil card end is provided with and is used for fixing the installing hole that connects gold utensil;
Described closed fixture end is used for fixedlying connected with the chapeau de fer of insulator.
As seen, in the utility model embodiment, the chapeau de fer of the insulator that the closed fixture end of jig can be adjacent with the insulator that needs are changed is fixedlyed connected, and its gold utensil card end then can be fixedly connected with the connection gold utensil that is connected insulator.Therefore, although first insulator of insulator string lead side has only the adjacent with it insulator of a slice, but the jig of the utility model embodiment can utilize its gold utensil card end and be connected gold utensil and fix, thereby the problem that gold utensil card end does not have fixing point can not occur, and then can realize replacing first insulator of insulator string lead side.

Embodiment
In order to make those skilled in the art person understand technical scheme in the utility model better, below in conjunction with the accompanying drawing among the utility model embodiment, technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all should belong to the scope of the utility model protection.
The enclosed jig is insulator a kind of jig commonly used of changing insulator string.In changing the process of insulator, the preceding card of enclosed jig and back card all will be fixed on the chapeau de fer of two insulators adjacent with the insulator that needs to change, and therefore have no idea to realize the replacing to first insulator in strain insulator string both sides.
In view of this, the utility model embodiment provides a kind of jig, solving preceding card or the no fixing point of back card that has only the existing jig that the adjacent with it insulator of a slice causes because of first insulator of insulator string lead side, and then the problem that can't change first insulator of insulator string lead side.
Fig. 1 a and Fig. 1 b show a kind of structure of above-mentioned jig, comprising: closed fixture end 1, laborsaving screw mandrel 2 and gold utensil card end 3;
Closed fixture end 1 is connected by laborsaving screw mandrel 2 with gold utensil card end 3.Wherein, gold utensil card end 3 specifically can be connected with laborsaving screw mandrel 2 by the connecting hole on it 31;
Closed fixture end 1 is used for fixedlying connected with the chapeau de fer of insulator;
Gold utensil card end 3 is used for to be connected gold utensil fixedly connected.
The quantity of the laborsaving screw mandrel 2 in the foregoing description can be one or more, and is advisable with two.
Fig. 2 shows the annexation of above-mentioned jig each several part when insulator is changed:
Closed fixture end 1 is fixed on the chapeau de fer of the insulator 6 adjacent with insulator that need to change 4, and gold utensil card end 3 is fixed in and insulator 4 adjacent being connected on the gold utensil 5 that need replacing.When changing, tighten up laborsaving screw mandrel 2, make insulator 4 lax after, insulator 4 is removed, carry out insulator and change.After installing new insulator, loosen laborsaving screw mandrel 2, make insulator string stressed, the insulator string homing.
As seen, in the present embodiment, the chapeau de fer of the insulator that the closed fixture end of jig can be adjacent with the insulator that needs are changed is fixedlyed connected, and its gold utensil card end then can be fixedly connected with the connection gold utensil that is connected insulator.Therefore, although first insulator of insulator string lead side has only the adjacent with it insulator of a slice, but the jig of present embodiment can utilize its gold utensil card end and be connected gold utensil and fix, thereby the problem that gold utensil card end does not have fixing point can not occur, and then can realize replacing first insulator of insulator string lead side.
