In 500 KV transmission line simply connected suspension insulator gold utensil compositions, yoke plate mainly adopts and shoulders formula yoke plate installation heavy punch piece, the design of droop yoke plate installation heavy punch piece, because of the reasons in structure of insulator string gold utensil, when causing restringing end along number first insulator, lack one and meet light, firm, that coefficient of safety is high conductor wire end end chucking appliance.
Under the end of past restringing end first insulator, card has three kinds: 1 to use wire lifting device to block as under end, and 2 use steel wire loop to block as under end, and 3 use U-shaped link as end card.These three kinds of methods respectively have pluses and minuses, and first kind of way method safety is safe, but instrument is heavy; The second tool method is light, but will carry out and anti-cut off measure, and steel wire loop is not easy fixing and has elongation, and the screw travel of needs is larger; The third method jig is simply easy to assembly, but U-shaped link and upper jig stressed inconsistent, and be not suitable for being arranged on the wire yoke plate of heavy punch piece, versatility is not strong.
Utility model content
The purpose of this utility model is to provide a kind of 500 KV transmission line simply connected suspension insulator conductor wire end jigs.Can change yoke plate in simply connected suspension insulator gold utensil composition shoulder on being formula yoke plate, on shoulder that formula yoke plate installs heavy punch piece, droop yoke plate, droop yoke plate install the conductor wire end first insulator of heavy punch piece, versatility is stronger.
The technical solution of the utility model is: a kind of 500 KV transmission line simply connected suspension insulator conductor wire end jigs, and the main center position of this jig is provided with a draw-in groove matched with yoke plate, for blocking yoke plate lower limb center; The deck other end is connected with main center position, and deck one end is placed into heavy punch piece and centre position, yoke plate lower limb space forms wire termination jig; Is connected in the middle of conductor wire end jig and yoke plate lower limb, by with load leading screw, upper card promotes with the use of, whole yoke plate can be promoted together with wire, just can carry out the operation of the suitable several first insulator string of restringing end.
Described main body is provided with two screws.
The beneficial effects of the utility model are:
1, the assembling solving former replacing instrument is numerous and diverse, heavy, coefficient of safety this key issue low, instrument lightweight, reasonable in design, and fitting operation is simple and convenient, alleviates the labour intensity of personnel and ground staff on tower, improves operating efficiency;
2, solve yoke plate be on shoulder formula yoke plate, droop yoke plate and droop yoke plate and the conductor wire end of the insulator string gold utensil composition form of heavy punch piece be installed along number more the changing jobs of first insulator, the card of main center position is utilized be nested with yoke plate lower limb centre position, steady, the safety of conductor wire end jig during guarantee lifting lead wire;
3, solve yoke plate be on shoulder formula yoke plate and the conductor wire end of the insulator string gold utensil composition form of heavy punch piece be installed along number more the changing jobs of first insulator, deck one end is connected with main center screw, deck one end is placed into heavy punch piece and centre position, yoke plate lower limb space, be pedestal with main body, both form end chucking appliance.Avoid the difficult problem because of heavy punch piece obstruction instrument safety.
4, in main body, be provided with two screws, be applicable to the insulator clamp apparatus of two kinds of different lengths, have larger versatility.
5, alleviate the labour intensity of operating personnel, shorten the activity duration, reach job safety, convenient, efficient object.
