The utility model discloses following beneficial effect has:

the utility model discloses simple structure is applicable to the loading and unloading of narrow and small space electric capacity, convenient to use, excellent in use effect.

Description of the drawings:

fig. 1 and fig. 2 are the structure diagrams of the present invention.

Fig. 3 is an internal structure diagram of the present invention.

Fig. 4 is a structural diagram of the middle clamping jaw of the utility model.

The specific implementation mode is as follows:

the present invention will be further described with reference to the accompanying drawings.

Like fig. 1 to 4, the utility model relates to a dismantlement anchor clamps of condenser in transformer, including mounting disc 11, guide post 12, mounting panel 13, clamping jaw 2, extension spring 3, spring 4, stop collar 5 and gag lever post 6.

The bottom and the mounting disc 11 threaded connection of guide post 12, top and mounting panel 13 threaded connection, three clamping jaw 2 articulates on mounting disc 11, and three extension spring 3 equipartition is on the circumferencial direction of guide post 12, and the one end of every extension spring 3 links to each other with clamping jaw 2, and the other end links to each other with guide post 12. Spring 4 and stop collar 5 all overlap and establish on guide post 12, and the top of spring 4 is contradicted on the internal face of stop collar 5, and the bottom is contradicted on the outer wall of guide post 12, and the vertical grafting of gag lever post 6 is on mounting panel 13, and the bottom of gag lever post 6 is contradicted on the up end of stop collar 5, and the lower port face of stop collar 5 is contradicted on the outer wall of all clamping jaws 2.

In order to install the clamping jaws 2 on the installation disc 11 conveniently, 3 installation grooves 111 are formed in the circumferential direction of the

installation disc

11, 3 hinge lugs 112 are formed in the upper end face of the installation disc 11, one clamping jaw 2 is arranged in each installation groove 111, and each clamping jaw 2 is hinged to the corresponding hinge lug 112 through a bolt.

In order to facilitate the installation and connection of the tension spring 3, the inner wall surface of the clamping jaw 2 and the outer wall surface of the guide column 12 are respectively provided with a connecting hook for connecting the tension spring 3.

A boss portion 121 is provided on an outer wall surface of the guide post 12, and a bottom end of the spring 4 is correspondingly abutted against the boss portion 121.

The utility model discloses well stop collar 5 is lower extreme opening, upper end confined circular sleeve structure, is equipped with the round hole in the centre of a circle department of 5 upper end closed surfaces of stop collar, and stop collar 5 wears to establish on guide post 12 through the round hole. The top end of the spring 4 is propped against the closed surface of the upper end of the limiting sleeve 5.

A rubber pad is bonded to the inner wall surface of the jaw 2. The rubber pad prevents scratching the surface of the capacitor.

When dismantling the electric capacity in narrow and small space, will the utility model discloses anchor clamps stretch in the transformer, and when three clamping jaw 2 was contradicted on the electric capacity outer wall, because the internal face of clamping jaw 2 is the inclined plane structure that leans out, continued to push down anchor clamps and make three clamping jaw 2 motion dorsad, extension spring 3 was stretched this moment. Then push down gag lever post 6, contradict stop collar 5 on three clamping jaw through gag lever post 6 for three clamping jaw tightly supports on the outer wall of electric capacity, then takes out electric capacity. Electric capacity passes through the utility model discloses the installation of anchor clamps is similar with the process of dismantling, the utility model discloses no longer describe.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications can be made without departing from the principle of the present invention, and these modifications should also be regarded as the protection scope of the present invention.
