Description

The transformer nut remover
Technical field
The present invention relates to a kind of provision for disengagement, specifically, related to the transformer nut remover that is used for the top nut of dismounting transformer low voltage sleeve pipe in a kind of power equipment maintaining work.
Background technology
At present, be provided with nut on the conductive lever of transformer low voltage sleeve pipe, because long-term heavy-duty service, nut and conductive lever can slightly weld together because of the sparking sintering phenomenon, when this nut of dismounting, conductive lever is rotated together with nut, and be by multilayer soft copper sheet and screw crimping between the low pressure winding in conductive lever lower end and the transformer-cabinet, bolt rotary can make the dislocation of soft copper sheet kink into twisted shape, causes conductive lever and low-voltage coil loose contact.Therefore usually need two maintenance personals to climb up simultaneously the transformer stand in the real work, a people is conductive lever fixedly, another people's nutting, however the operating space on the transformer stand is limited, and work is dangerous to be increased.
In order to solve the problem of above existence, people are seeking a kind of desirable technical solution always.
Summary of the invention
The objective of the invention is for the deficiencies in the prior art, thereby but provide a kind of design science, transformer nut remover simple, the convenient disassembly one man operation is installed.
To achieve these goals, the technical solution adopted in the present invention is: a kind of transformer nut remover, and it comprises the limiting plate with spacing hole, two fastening screws and two clamp nuts that are arranged on the described limiting plate; Wherein, two described clamp nuts are along the same central axis setting that is parallel to described limiting plate, and two described fastening screws are separately positioned in two described clamp nuts, and described spacing hole is between two described clamp nuts.
Based on above-mentioned, this transformer nut remover also comprises grip block, and described grip block one end is provided with threaded arc groove, and the other end is provided with jack, and an end of described fastening screw is arranged in the described jack.
Based on above-mentioned, be provided with fixed screw on the described grip block, the corresponding described fixed screw of described fastening screw one end is provided with holddown groove.
Based on above-mentioned, described limiting plate both sides correspondence is provided with stopper slot.
Based on above-mentioned, described limiting plate one side is provided with stopper slot.
The relative prior art of the present invention has outstanding substantive distinguishing features and marked improvement, specifically, the present invention utilizes screwed grip block to fix conductive lever, well fixed limiting plate by stopper slot again, the nut dismounting that the staff can effectively will slightly be welded with spanner gets off.This transformer nut remover has advantages of design science, but simple, convenient disassembly one man operation is installed.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is working state schematic representation of the present invention.
Fig. 3 is the structural representation of embodiment 2.
Among the figure: 1. spacing hole; 2. limiting plate; 3. fastening screw; 4. clamp nut; 5. grip block; 6. arc groove; 7. jack; 8. fixed screw; 9. holddown groove; 10. stopper slot; 11. conductive lever; 12. insulator.
The specific embodiment
Below by the specific embodiment, technical scheme of the present invention is described in further detail.
Embodiment 1
As shown in Figure 1, a kind of transformer nut remover, it comprises the limiting plate 2 with spacing hole 1, two fastening screws 3 and two clamp nuts 4 that are arranged on the described limiting plate 2, and described limiting plate 2, described fastening screw 3 and described clamp nut 4 all adopt metal material.Wherein, two described clamp nuts 4 are along the same central axis setting that is parallel to described limiting plate 2, being about to two clamp nuts 4 is symmetrically welded on described limiting plate 2 the same sides, two described fastening screws 3 are separately positioned in two described clamp nuts 4, the screw rod of two described fastening screws 3 arranges in opposite directions, described spacing hole 1 is between two described clamp nuts 4, as shown in Figure 2, the diameter of described spacing hole 1 is greater than the diameter of common conductive lever 11 top nuts, is convenient to limiting plate 2 is enclosed within on the described conductive lever 11.
As shown in Figure 1, this transformer nut remover also comprises grip block 5, described grip block 5 one ends are provided with threaded arc groove 6, the design benefit is to come the external screw thread of clamping conductive lever by the screw thread of arc groove 6 like this, that not only fixes is firm, and does not damage the external screw thread of described conductive lever; The other end is provided with jack 7, one end of described fastening screw 3 is arranged in the described jack 7, design is equivalent to provide two kinds of method of clamping like this, a kind of is to carry out clamping by grip block 5, another kind directly utilizes fastening screw 3 to carry out clamping, and certain this connection of living also is convenient to change described grip block 5.
Be provided with fixed screw 8 on the described grip block 5, the corresponding described fixed screw 8 of described fastening screw 3 one ends is provided with holddown groove 9.In the described holddown groove 9 of described fixed screw 8 precessions, do not need to be screwed to the end, only otherwise allowing described grip block 5 come off gets final product.
As shown in Figure 1 and Figure 2, described limiting plate 2 both sides correspondences are provided with stopper slot 10.The width of described stopper slot 10 should greater than the diameter of common conductive lever 11 top nuts, be convenient to stopper slot 10 is enclosed within on the conductive lever 11 of the insulator 12 that faces mutually, to limit the axial-rotation of described limiting plate 2.
During work, this transformer nut remover is installed on the conductive lever 11 on transformer insulated sub 12 as shown in Figure 2, the described fastening screw 3 of turn, two described clamping parts 5 are stepped up described conductive lever 11, because described stopper slot 10 gears are on the conductive lever that faces mutually, so that the conductive lever 11 in the described spacing hole 1 can not rotate, be that available spanner is unscrewed the target nut on this conductive lever 11 this moment.
Embodiment 2
Embodiment 2 compares with embodiment 1, and difference is: described limiting plate 2 one sides of limiting plate are provided with stopper slot 10.This structure is simpler, and can adapt to the situation of next door when barrier is arranged, and only needs limit limited location groove to get final product work.
Should be noted that at last: above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit; Although with reference to preferred embodiment the present invention is had been described in detail, those of ordinary skill in the field are to be understood that: still can make amendment or the part technical characterictic is equal to replacement the specific embodiment of the present invention; And not breaking away from the spirit of technical solution of the present invention, it all should be encompassed in the middle of the technical scheme scope that the present invention asks for protection.
