Accompanying drawing explanation
Fig. 1 is that in the preferred embodiment of the present invention, a kind of two strings of strain insulators cross-arm side connects the structural representation that hardware fitting with electrical is changed jig;
Embodiment
Below the present invention will be further described in conjunction with the accompanying drawings and embodiments.
Two strings of strain insulators cross-arm side connects hardware fitting with electrical and changes a jig, comprising: front card 1 and rear card 2, and the both sides of described front card 1 and rear card 2 are connected by screw mandrel 3 respectively; Described screw mandrel 3 comprises a sleeve pipe 31, and the inwall of described sleeve pipe 31 is provided with screw thread, and the two ends of described sleeve pipe 31 are connected with respectively screw rod 32, and the screw thread of described screw rod 32 is corresponding with the screw thread of described sleeve pipe 31 inwalls; The outer wall of described sleeve pipe 31 is socketed with the actuating rod vertical with described sleeve pipe 33, the outer wall close contact of described actuating rod 33 and described sleeve pipe 31, when described actuating rod 33 is rotated in the forward, described screw rod 32 moves towards the direction near described sleeve pipe 31, thereby described screw mandrel 3 is shunk; Described actuating rod anti-33 is to when rotation, and described screw rod 32 is towards the direction motion away from described sleeve pipe 31, thereby described screw mandrel 3 is extended; When described screw mandrel 3 extends, described front card 1 can hold at least one insulator 4 and the described gold utensil 5 that is connected with the space between rear card 2.
On described front card 1, have symmetrical clamp 11, one end of described clamp 11 is connected on described front card 1 by rotating shaft 12, and the other end of described clamp 11 is by bolt 13 and described front card 1 locking; During described clamp 11 locking and between described front card 1, form the first through hole 14, the shape of described the first through hole 14 is corresponding with the steel cap 41 of described insulator 4;
The middle part of described rear card 2 has the connector 22 with rear card 2 lockings by bolt 21, during described connector 22 locking and between described rear card 2, forms the second through hole 23, and it is 51 corresponding that the shape of described the second through hole 23 and the prolongation of described connection gold utensil encircle.In the present embodiment, described the second through hole 23 at least two size shape are identical, join end to end, and the via chain that forms of the through hole being perpendicular to one another.
While using above-mentioned jig to change operation, be mainly divided into following steps:
1) on tower, the #1 electrician's belt little lifting rope that insulate is stepped on to wire cross-arm position, fastens seat belts, and ties up insulated sling, hangs on insulating bar, the jig assembling and protection rope hook etc.On tower, on #2 electrician, tower, guardian steps on tower in succession.
2) on tower, #1, #2 electrician's cooperation install jig, are specially: the first through hole 14 blocking before described jig on 1 is locked with the steel cap 41 of insulator 4; By the second through hole 23 on described rear card 2 and prolongation ring 51 lockings that are connected gold utensil 5;
3) on tower, #1 electrician is rotated in the forward actuating rod 33, screw mandrel 3 is shortened, thereby make the stressed increase of described jig, connects the stressed of gold utensil 5 and reduces; When described connection gold utensil 5 does not stress completely, actuating rod 33 stops the rotation; On tower, #1 electrician carries out shock test, guarantees stressed evenly reliable.
4) on tower, #1 electrician removes the connection gold utensil 5 getting rusty, and on tower, electrician, ground electrician coordinate the connection gold utensil 5 more renewing.
5) on tower, #1, #2 electrician coordinate and install newly connecting gold utensil 5, and check connection.
6) #1 electrician's reverse rotation actuating rod 33 on tower, extends screw mandrel 3, thereby makes that described jig is stressed to be reduced, and connects the stressed increase of gold utensil 5; When described jig does not stress completely, actuating rod 33 stops the rotation; On tower, #1 electrician carries out shock test, guarantees stressed evenly reliable.On tower, electrician removes jig, checks without lower tower after legacy.
The above, be only preferred embodiment of the present invention, not technical scope of the present invention imposed any restrictions, therefore any trickle modification that every foundation technical spirit of the present invention is done above example, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
