Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
In description of the present utility model, except as otherwise noted, term " on ", the orientation of the instruction such as D score or state relation be based on orientation shown in the drawings or state relation, only the utility model and simplified characterization for convenience of description, instead of the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
In description of the present utility model, it should be noted that, unless otherwise clearly defined and limited, term " connection " should be interpreted broadly, and such as, can be fixedly connected with, also can be removably connect, or connect integratedly; Can be directly be connected, also indirectly can be connected by intermediary.For the ordinary skill in the art, concrete condition the concrete meaning of above-mentioned term in the utility model can be understood.
Embodiment one
As shown in Figure 2, a kind of outdoor high-voltage current-limiting fuse dismantling device, comprises two rhizoid bar 6 and two block pressur plates 7.The diameter of screw mandrel 6 is 8mm, overall long 780mm; The long 165mm of pressing plate 7, middle part has U-shaped opening 71, the wide 22mm of U-shaped opening 71, the two ends of pressing plate 7 offer porose 72 respectively, and the spacing of holes 72 is 115mm, and the diameter in hole 72 and the external diameter of screw mandrel 6 adapt, two block pressur plate 7 correspondences are arranged, and the opening direction of U-shaped opening 71 is consistent.Corresponding inserted is in the hole 72 of two block pressur plates 7 respectively at the two ends of two rhizoid bars 6, and namely the two ends of a rhizoid bar 6 are plugged in the hole 72 of one end of two block pressur plates 7 respectively, and the two ends of another rhizoid bar 6 are plugged in the hole 72 of the other end of two block pressur plates 7 respectively; On every rhizoid bar 6, and the outside being positioned at two block pressur plates 7 is all socketed with nut 8, by twisting nut 8, two block pressur plates 7 is moved on two rhizoid bars 6 in opposite directions.
During use, by the distance adjustment between two block pressur plates 7 to adapting with the length of high-voltage and current-limitation fuse, two U-shaped openings 71 are blocked respectively and is set on the terminals 5 at high-voltage and current-limitation fuse two ends, insulator 1 is between two screw mandrels 6; The nut 8 at twisting screw mandrel 6 two ends, by two pressing plates 7, two terminals 5 caps 4 are pressed in opposite directions, by the elastic force of counteracted by pressure part in opposite directions from the power spring inside terminals 5 cap 4, the axle box pressure of the holding screw on two terminals 5 caps 4 reduces thereupon, can twist bolt easily thus; Pressing with the outside of terminals 5 cap 4 due to pressing plate 7 is in addition that face contacts, in the process of assembling-disassembling bolt successively, relative angle between terminals 5 cap 4 and insulator 1 can not change in the effect of power spring elastic force, the disassembling section of each like this bolt is very convenient, after all bolts are all dismantled, move integrally pressing plate 7 again, complete dismantlement work, efficient dismounting can be realized thus.
Preferably, this dismantling device also comprises bandage 9, and bandage 9 is set in outside two rhizoid bars 6, for being fixed between two screw mandrels 6 by insulator 1, drops in case terminals 5 cap 4 at insulator 1 two ends is dismantled rear insulator 1.Bandage 9 can be set to many, and such fixed effect is better; Bandage 9 can select magic tape, bonding convenient with tearing movement.
The two ends of each pressing plate 7 can also offer multiple hole 72 respectively, and in using according to reality, the external diameter of insulator 1, plugs screw mandrel 6 in different holes 72, make to have suitable distance between two screw mandrels 6.
Every rhizoid bar 6 also can arrange coating layer, and coating layer can be plastic flexible pipe, and coating layer is positioned at the inner side of two block pressur plates 7, prevents the outer wall of screw mandrel 6 scratch insulator 1.
Embodiment two
A kind of outdoor high-voltage current-limiting fuse dismantling device that the present embodiment two provides, substantially identical with the structure of embodiment one, something in common repeats no more, and difference is:
On every rhizoid bar 6, and the inner side being arranged in a block pressur plate 7 of two block pressur plates 7 is all socketed with nut 8, thus make the both sides screw mandrel 6 of this pressing plate 7 is equipped with nut 8, the axial location of this pressing plate 7 on screw mandrel 6 can be made thus to fix, in the use of reality, can first this pressing plate 7 card be set on the terminals 5 of high-voltage and current-limitation fuse one end, because the position of this pressing plate 7 is fixed, the axial changing of the relative positions or angle change can not be there is relative to screw mandrel 6, therefore easy to operate, improve efficiency and the fail safe of operation, this dismantling device structure is simple in addition, cost is low, be suitable for promoting the use of.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and replacement, these improve and replace and also should be considered as protection range of the present utility model.
