Abstract
The utility model discloses an overturning plate clamp fixture for live-line work, comprising a clamp fixture body formed by hinge joint of a front clamping plate and a rear clamping plate, wherein the middle part of the front clamping plate is provided with a through hole I, the middle part of the rear clamping plate is provided with a through hole II corresponding to the through hole I, the through hole I is provided with an inner sleeve I therein connected detachably with the front clamping plate, and the through hole II is provided with an inner sleeve II therein connected detachably with the rear clamping plate. Due to that the inner sleeve I and the inner sleeve II are respectively detachably connected with the clamp fixture body, the overturning plate clamp fixture for live-line work is suitable to different power transmission lines by replacing inner sleeves, has strong interchangeability, and can adapt the troubleshooting need of the different power transmission lines. Simultaneously, the radial cross section of the inner sleeve I and the inner sleeve II is regular hexagon, the inner sleeve I and the inner sleeve II contact with nuts therein through surfaces, and are not easily damaged. The overturning plate clamp fixture for live-line work has excellent bearing performance and has long service life.
Description
Technical field
The utility model relates to a kind of insulator and changes instrument, particularly a kind of turnover panel card.
Background technology
The turnover panel card is a kind of jig of charged for replacement insulator, and it comprises the preceding clamp of combining through hinged mode and back clamp.
In the prior art, preceding clamp is provided with corresponding through hole with clamp middle part, back, is set with ring inner sleeve in the two through hole respectively, and interior cover is used to place the nut bolt assembly, and bolt assembly is used for connecting with the gold utensil that is connected insulator.
The turnover panel card of this structure, interior cover can not be changed for fixedly installing; Therefore can not adapt to different connection gold utensils, adaptability is relatively poor, and being applied in of turnover panel card is widely used in the line maintenance; Because receive the restriction of fixing interior cover, the interchangeability of turnover panel card is relatively poor, can not adapt to the maintenance needs.
Because interior cover is that line contacts with the nut of bolt assembly, and contact site pressure is bigger, cover damages in causing easily simultaneously.
Therefore need stick into row to turnover panel of the prior art and improve,,, overlap stress performance in also need improving simultaneously, with summary its useful life to adapt to maintenance needs of different transmission lines to strengthen its interchangeability.
The utility model content
In view of this, the purpose of the utility model provides a kind of live line working turnover panel card jig, and it has stronger interchangeability, can adapt to the maintenance needs of different transmission lines, and cover has stress performance preferably in it simultaneously, and is not easy to wear, long service life.
The utility model live line working turnover panel card jig; Comprise by preceding clamp and the hinged jig main body of forming of back clamp; Preceding clamp middle part is provided with the through hole I; Back clamp middle part is provided with the through hole II corresponding with the through hole I, is provided with the interior cover I that is connected with preceding clamp detachable in the through hole I, is provided with the interior cover II that is connected with back clamp detachable in the through hole II.
Further, the endoporus radial section of said interior cover I and interior cover II is regular hexagon;
Further, said through hole I and through hole II are stepped hole, and the relative end with the through hole II of through hole I is the macropore of stepped hole, and the external surface shape of interior cover I and interior cover II is adaptive with the through hole that matches with it respectively;
Further, said interior cover I and through hole I are rotatably assorted, and interior cover II and through hole II are rotatably assorted.
The beneficial effect of the utility model: the utility model live line working turnover panel card jig; Cover I is connected with jig main body detachable with interior cover II in it; Can make this turnover panel card jig be applicable to different transmission lines through cover in changing; Thereby have stronger interchangeability, can adapt to the maintenance needs of different transmission lines; Simultaneously radial section of cover I and interior cover II is a regular hexagon in it, be arranged in nut in the cover be that face contacts, stress performance is better, interior cover is not fragile, long service life.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Fig. 1 is the structural representation of live line working turnover panel card jig;
Fig. 2 is the structural representation of jig main body;
Fig. 3 is the elevational schematic view of interior cover II.
Embodiment
Fig. 1 is the structural representation of live line working turnover panel card jig; Fig. 2 is the structural representation of jig main body; Fig. 3 is the elevational schematic view of interior cover II.
As shown in the figure; Present embodiment live line working turnover panel card jig; Comprise that preceding clamp 1 middle part is provided with through hole I 1a by preceding clamp 1 and the back clamp 2 hinged jig main bodys of forming, back clamp 2 middle parts are provided with the through hole II 2a corresponding with the through hole I; Be provided with the interior cover I 3 that is connected with preceding clamp 1 detachable among the through hole I 1a, be provided with the interior cover II 4 that is connected with back clamp detachable among the through hole II 2a.The utility model live line working turnover panel card jig; Cover I is connected with jig main body detachable with interior cover II in it; Can make this turnover panel card jig be applicable to different transmission lines through cover in changing, thereby have stronger interchangeability, can adapt to the maintenance needs of different transmission lines; In be enclosed within the practical application and can make the different series specification, be convenient to change.
As the improvement to this embodiment, the endoporus radial section of said interior cover I 3 and interior cover II 4 is regular hexagon; The shape of the endoporus 4a of cover II 4 in from Fig. 3, can finding out.In the radial section of cover I and interior cover II be regular hexagon, thereby be arranged in nut in the cover be that face contacts, stress performance is better, interior cover is not fragile, long service life.
As improvement to this embodiment; Said through hole I 1a and through hole II 2a are stepped hole; The relative end with the through hole II of through hole I is the macropore of stepped hole; The external surface shape of interior cover I 3 and interior cover II 4 is adaptive with the through hole that matches with it respectively, overlaps slippage in this structure can prevent, reliability is higher.
As the improvement to this embodiment, said interior cover I 3 is rotatably assorted with through hole I 1a, and interior cover II 4 is rotatably assorted with through hole II 2a; Interior cover I 3 is rotatable with interior cover II 4 stressed backs, thereby can adjust interior cover position automatically, to adapt to the installation needs, can reduce the wearing and tearing of mating surface simultaneously.
Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although with reference to preferred embodiment the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model; And not breaking away from the aim and the scope of the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.
