Fig. 1 is structural representation of the present invention;
Fig. 2 is that Fig. 1 master card is removed the A of removable cover to view;
Fig. 3 is the B-B broken section enlarged drawing of Fig. 1.
Embodiment
Such as Fig. 1, Fig. 2, Fig. 3, the device of the above transmission line monolithic insulator of 35kV is changed in charged or power failure, master card before and after comprising is connected with connection and is tightened up screw mandrel, and the present invention's single insulator holder is set to by master card 1 and is connected to the subcard 2 of master card endoporus and tightens up screw mandrel 3 form; Wherein master card 1 is along the syndeton of half employing removable cover 4 of endoporus, and namely removable cover 4 adopts hinge pin 5 to be connected with master card 1 one ends, and the other end adopts and is connected with master card bolt 6; Subcard 2 is set to two semicircular cylinders to be separately fixed in master card endoporus 7 and the removable cover endoporus 8.The contact-making surface of the circumferential surface of the present invention's master card 1 inner hole surface and subcard 2 is set to taper surface 12; Be provided with a support level 13 on the top of subcard 2; Be provided with anticreep hole 9 and strong adsorption magnet 10 in master card and removable cover inner hole wall; And be provided with the locking pin corresponding with the anticreep hole 11 at the subcard cylinder body outer wall.
1. design principle of the present invention
This cover combination tool designs by master card 1 and subcard 2 and tightens up screw mandrel 3 and forms.
1) this combination tool adopts the design of child and parent card, namely master card is made into universal card, comes the sub-steel cap of coordinated insulation by subcard, then subcard is installed on the master card, form child and parent card, we only need corresponding different insulator steel cap to change subcard to get final product in the work.
2) because the differing greatly of the overall dimension of insulator steel cap, therefore general execution mode can be divided into master card 7-12T, 16T, four kinds of specifications of 21T, 30T, can satisfying under the prerequisite of job requirement, reduce as much as possible the weight of jig like this.
2. the fit form of child and parent card determines
The type of attachment of child and parent card adopts the removable cover syndeton, can open easily removable cover and change the monolithic subcard that is fit to; Elect the fit form of child and parent card the connection of taper surface locking+strong adsorption magnet+locking pin as, rather than directly being fixedly connected with by screw in the past.The power that acts on the subcard is effectively passed on the master card main body, rather than on the attachment screw of child and parent card, thereby avoid because hold-down screw is cut off, cause subcard to come off or problem that the screw distortion can't be dismantled subcard.
The cooperation of taper surface locking: the present invention elects the fit form of subcard and master card as taper surface 12; When jig is stressed, subcard can to taper surface 12 the top slight displacement occurs, make subcard embrace more closely insulator steel cap, suffered power is conducted more effectively to master card, avoid the situation of subcard or master card local pressure, thereby effectively guaranteed the use safety of jig.
The cooperation of support level: the support level 13 that is provided with in subcard 2 upper ends is be used to bearing the suffered larger pulling force of subcard, and support level 13 can be transferred to master card with suffered larger pulling force, can effectively avoid jig to be damaged.
Strong adsorption magnet: the present invention selects strong adsorption magnet 10 fixing the type of attachment of subcard and master card; In real work when jig is stressed, subcard 2 can to taper surface 12 the top slight displacement occurs, should guarantee that subcard is connected tight connection with master card, allow again subcard and master card that slight displacement is arranged, if adopting screw fixes, occur possibly because hold-down screw is cut off, cause subcard to come off or situation that screw distortion can't be dismantled subcard, so the selected subcard of the present invention and master card be connected to strong adsorption magnet 10 fixed forms, in order to guarantee the enough of absorption affinity, can according to circumstances increase area or the quantity of strong adsorption magnet 10.
Install locking pin additional: the present invention finds after selecting the utilizing powerful magnet for adsorption formula fixing the type of attachment of subcard and master card, subcard is larger with the vertical the suction-combining force of master card, but horizontal the suction-combining force is less, the situation that subcard comes off may occur when subcard is subject to power to conical surface bottom.Therefore the present invention has been installed a locking pin 11 additional at subcard, has so just avoided subcard because of the stressed problem that comes off.
3. the assembling of child and parent card
Owing to adopted the connected mode of the locking conical surface+strong adsorption magnet+locking pin, the assembling of Here it is child and parent card becomes very convenient, quick.
Master card is divided into front and rear card, there are two subcards to be contained in respectively on the main body and removable cover of master card on every master card, difference according to the actual use of circuit insulator, we are placed directly in the master card junction with corresponding subcard, strong adsorption magnet can be attached together subcard and master card automatically, as long as we are with the anticreep hole on the aligning of the locking pin on the subcard master card, and assembling only needs 6-10 can finish in second once the cover jig.
4. experimental study project
1) mechanical performance-laboratory test of titanium alloy master card is finished
2) overall mechanical properties-laboratory test of combination tool is finished
3) versatility of combination tool, reasonability, flexible operation-execute-in-place checking, improvement, optimization.
Working method is as follows:
First master card 1 (front and rear card) is connected when the present invention works and tighten up screw mandrel 3, to directly be placed in the interior die cavity of master card 1 with the subcard 2 (each two of front and rear cards) that insulator is complementary again, utilize the strong adsorption magnet 10 on the child and parent card that subcard and master card are pulled together, locking pin 11 is placed anticreep hole 9, and jig is just assembled complete.Because the fit form of subcard and master card is elected taper surface 12 as; When jig is stressed, subcard can to taper surface the top slight displacement occurs, make subcard embrace more closely insulator steel cap, simultaneously suffered power is conducted more effectively to master card, avoid the situation of subcard or master card local pressure, thereby effectively guaranteed the use safety of jig.In real work when jig is stressed, subcard can to taper surface the top slight displacement occurs, be connected tight connection with master card as guaranteeing subcard, allow again subcard and master card that slight displacement is arranged, if adopt screw to fix, occur possibly because hold-down screw is cut off, cause subcard to come off or situation that the screw distortion can't be dismantled subcard, through deliberating repeatedly the utilizing powerful magnet for adsorption formula that the is connected to fixed form of the selected subcard of the present invention and master card.Find that subcard is larger with the vertical the suction-combining force of master card after selecting strong adsorption magnet fixing the type of attachment of subcard and master card, but horizontal the suction-combining force is less, when subcard is subject to power bottom the taper surface, the situation that subcard comes off may occurs.Therefore the present invention has been installed a locking pin additional at subcard, has so just avoided subcard because of the stressed problem that comes off, and makes it safer, practical, reliable.Jig of the present invention is merged into various ways with charged or the numerous types of changing the monolithic insulator jig that have a power failure, and satisfies various insulators by changing subcard, and easy to operate, the respond well requirements that meets has reached Expected Results.
