Wherein, above-mentioned transformer conducting bar fixture also comprises the 3rd fixture block and the 4th fixture block of replacing first fixture block and second fixture block.

Wherein, the relative inner of above-mentioned first fixture block and second fixture block has arc opening.Further, above-mentioned arc opening can have toothed surfaces.

Wherein, the end of above-mentioned puller bolt forms handle.

Wherein, the outside of the framework of above-mentioned transformer conducting bar fixture has handle.

Wherein, the length direction along framework stretches out above-mentioned handle from the corner of framework.

Wherein, the Width along framework stretches out above-mentioned handle from the corner of framework.

Wherein, above-mentioned framework is rectangle, and crossbeam is parallel to the broadside of framework.

Use pliers clamping transformer conducting bar to compare with prior art, use fixture clamping transformer conducting bar of the present utility model, can make transformer conducting bar be in firm clamp position by screwing puller bolt, the frame that grips fixture again can prevent the transformer conducting bar rotation when operation.

Be noted that the description and the following detailed description all are exemplary, being intended to provides further instruction to desired the utility model.

Except purpose described above, feature and advantage, the utility model also has other purpose, feature and advantage.Below with reference to figure, other purpose, feature and effect of the present utility model is described in further detail.

Embodiment

Below the utility model is described in detail.

Transformer conducting bar fixture of the present utility model when the maintenance transformer, substitutes pliers, is used for the firm grip transformer conducting bar.It comprises: framework has crossbeam that can be free to slide and the part that holds out against that holds out against crossbeam on it; And first fixture block and second fixture block, be installed on respectively on described framework and the described crossbeam; Wherein, form the grasping part of transformer conducting bar between described first fixture block and second fixture block.Below in conjunction with each embodiment above-mentioned each feature is made an explanation.

Fig. 1 shows the transformer conducting bar fixture according to the utility model first embodiment.As shown in the figure, framework 110 is rectangle, and framework 110 is provided with the crossbeam (slide block) 150 that is parallel to framework broadside 111, and this crossbeam 150 can be free to slide along the length direction of framework 110.In a side of crossbeam 120, form the part that holds out against of crossbeam 150 by puller bolt 120, screw this bolt 120 and can force crossbeam to move.

A pair of fixture block (first fixture block and second fixture block) 131,133 is installed on the frame 110 respectively and on the crossbeam 150, this first fixture block and second fixture block 131,133 are interchangeable by screw.Opposed inside has arc opening 131B, 133B on this first fixture block 131 and second fixture block 133, has formed the grasping part of transformer conducting bar between these two arc openings that match.Also has toothed surfaces 131A on this arc opening, with firm clamping transformer conducting bar.

In the outside of framework 110, stretch out one handle (handgrip) 140 from corner, this handle 140 extends along the length direction of framework 110, and is parallel with the length direction of puller bolt 120, grips for operating personnel.This handle can be welded on the framework, also can be bolted on the framework.

Fig. 2 shows a selectable fixture block assembly of transformer conducting bar fixture shown in Figure 1; Fig. 3 shows another the selectable fixture block assembly that is used for transformer conducting bar fixture shown in Figure 1.As shown in Figure 2, fixture block assembly 130 comprises on the 3rd fixture block 132 and the 4th fixture block 134, the three fixture blocks 132 and the 4th fixture block 134 having

screw hole

132A, 134A respectively.Wherein, arc opening 132B on the 3rd fixture block 132 is different with the arc opening size on second fixture block with first fixture block of first embodiment with arc opening 134B on the 4th fixture block 134, like that, can form a series of sizes, for the transformer conducting bar use of different-diameter.There is not the arc bayonet socket on two fixture blocks 135,136 of the fixture block assembly 130 shown in Fig. 3, so that the clamping plane, two jiaos of nuts of clamping for example, like this, transformer conducting bar fixture of the present utility model then has other purposes by changing the fixture block assembly.

Fig. 4 shows the transformer conducting bar fixture according to the utility model second embodiment.As shown in the figure, the present embodiment and the first embodiment difference are that handle extends easier like this gripping along the Width of framework 110.
