Description
Technical field
The utility model relates to lightning arrester technical field, more particularly, and particularly a kind of lightning conductor installation bolt assembly.
Background technique
The lightning conductor of electric substation is high building, also different according to the different height of corresponding grade, for 220kV electric substation: 220 battery limits terminal height are 30 meters, 110kV battery limits terminal height is 25 meters, the structure of current For Lightning-Rod Protection Disign In Substations is knockdown structure, its lower floor is cement post, and upper strata is die structure, and middle joint needs bolt to fix.Due to upper strata lightning conductor by strong wind, etc. harsh weather affect for a long time lower directly cause bolt looseness nut cause lightning conductor rupture collapse consequence by hardly imaginable.If lightning conductor occurs collapse or Inclination Accident, not only can cause the damage of station equipment, also will cause large-area power outage, have a strong impact on society and people's lives.
Model utility content
(1) technical problem that will solve
Avoid nut, improve the stability that lightning conductor is installed.
(2) technological scheme
A kind of lightning conductor installation bolt assembly, comprising:
Bolt, one end of described bolt is hexagon end head, and the other end of described bolt is provided with outside thread, on described bolt, offer hinge last;
Nut, described nut is connected with described bolt thread;
Pad, described pad comprises flat gasket and compression spring, and described pad is sheathed between described nut and described hexagon end head;
Metal bolt, described metal bolt is inserted in described hinge last.
Preferably, described bolt is 8.8 grades of antiseptic and rustproof bolts of the high-strength hot galvanizing of M18*50.
Preferably, the utility model also includes fixation plate, and described fixation plate is rectangular configuration, and on each corner position of described fixation plate, offer mounting hole, described bolt is arranged in described mounting hole.
(3) beneficial effect
In said structure design, pad is provided with between nut and hexagon end head, pad comprises flat gasket and compression spring, flat gasket can increase the area of contact between hexagon end head and pedestal, thus avoid hexagon end head to apply the excessive damage pedestal of active force to pedestal, compression spring can apply pretightening force to nut, thus increases the active force between nut and bolt, avoids nut loosening.In addition, hinge last offered by bolt, and in hinge last, be provided with metal bolt, metal bolt can offset with nut, metal bolt has to nut the effect of halting, thus reaches and avoid the situation of nut loosening to occur, in this structural design, if need to pull down nut, then only need to pull down metal bolt in advance and get final product loose nut.
Designed by said structure, use the phenomenon that can not loosen, thread off between the utility model bolts and nuts, ensured the safe and stable operation of equipment more safely and effectively simultaneously, effectively reinforce the stability of lightning conductor.
