Description
Technical field
The present invention relates to a kind of provision for disengagement, specifically, relate in a kind of power equipment maintaining work for dismantling the transformer nut remover of transformer low voltage sleeve pipe top nut.
Background technology
At present, the conductive lever of transformer low voltage sleeve pipe is provided with nut, due to long-term heavy-duty service, nut and conductive lever slightly can weld together because of sparking sintering phenomenon, when dismantling this nut, conductive lever can be made to rotate together with nut, and be crimp by multilayer soft copper sheet and screw between conductive lever lower end and the low pressure winding in transformer-cabinet, bolt rotary can make soft copper sheet misplace and kink into twisted shape, causes conductive lever and low-voltage coil loose contact.Therefore usually need two maintenance personals to climb up transformer rack in real work, a people fixes conductive lever, another people's nutting simultaneously, but operating space in transformer rack is limited, and work risk increases.
In order to solve above Problems existing, people are seeking a kind of desirable technical solution always.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, thus a kind of design science is provided, simple, convenient disassembly is installed, can the transformer nut remover of one man operation.
To achieve these goals, the technical solution adopted in the present invention is: a kind of transformer nut remover, and it comprises with the limiting plate of spacing hole, two fastening screws and two clamp nuts be arranged on described limiting plate; Wherein, two described clamp nuts are arranged along the same central axis being 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 one end of described fastening screw is arranged in described jack.
Based on above-mentioned, described grip block is provided with fixed screw, the corresponding described fixed screw in 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 side is provided with stopper slot.
Hinge structure 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 fix limiting plate by stopper slot again, staff can be got off by the nut dismounting slightly welded by effective spanner.This transformer nut remover has design science, it is simple to install, convenient disassembly, can the advantage of one man operation.

Detailed description of the invention
Below by detailed description of the invention, 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 limiting plate 2, two fastening screws 3 with spacing hole 1 and two clamp nuts 4 be arranged on 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 arranged along the same central axis being parallel to described limiting plate 2, be symmetrically welded on described limiting plate 2 the same side by two clamp nuts 4, two described fastening screws 3 are separately positioned in two described clamp nuts 4, the screw rod of two described fastening screws 3 is arranged 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 screw rod 11 top nut, is convenient to limiting plate 2 to be enclosed within described conductive lever 11.
As shown in Figure 1, this transformer nut remover also comprises grip block 5, described grip block 5 one end is provided with threaded arc groove 6, such design benefit is the external screw thread being clamped conductive lever by the screw thread of arc groove 6, 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 described jack 7, such design is equivalent to provide two kinds of method of clamping, one is clamped by grip block 5, another kind directly utilizes fastening screw 3 to clamp, and certain this connection of living also is convenient to change described grip block 5.
Described grip block 5 is provided with fixed screw 8, and the corresponding described fixed screw 8 in described fastening screw 3 one end is provided with holddown groove 9.By in holddown groove 9 described in the precession of described fixed screw 8, do not need to be screwed to the end, only otherwise allow described grip block 5 come off.
As shown in Figure 1 and Figure 2, described limiting plate 2 both sides correspondence is provided with stopper slot 10.The width of described stopper slot 10 should be greater than the diameter of common conductive screw rod 11 top nut, is convenient to be enclosed within the conductive lever 11 of adjacent insulator 12 by stopper slot 10, to limit the axial-rotation of described limiting plate 2.
During work, this transformer nut remover is arranged on as shown in Figure 2 on the conductive lever 11 on transformer insulated sub 12, fastening screw 3 described in turn, two described clamping parts 5 are stepped up described conductive lever 11, because described stopper slot 10 keeps off on adjacent conductive lever, conductive lever 11 in described spacing hole 1 can not be rotated, and now namely the target nut on this conductive lever 11 unscrewed by available spanner.
embodiment 2
Embodiment 2 is compared with embodiment 1, and difference is: described in limiting plate, limiting plate 2 side is provided with stopper slot 10.This structure is simpler, and can adapt to situation when there is a barrier on side, only needs limit limited location groove to get final product work.
Finally should be noted that: 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 to invention has been detailed description, those of ordinary skill in the field are to be understood that: still can modify to the specific embodiment of the present invention or carry out equivalent replacement to portion of techniques feature; And not departing from the spirit of technical solution of the present invention, it all should be encompassed in the middle of the technical scheme scope of request of the present invention protection.
