Description
Technical Field
The utility model relates to a linkage's technical field, more specifically say so and relate to insulator linkage's technical field.
Background
The composite insulator is an insulation control widely applied to an electric power system, can play an important role in an overhead transmission line, is used for supporting and fixing a bus and a live conductor and enables the live conductor to have enough distance and insulation. At present, common composite insulators can be classified into rod type composite insulators for suspension, pin type composite insulators, cross arm composite insulators, pillar composite insulators and the like. Hang with excellent formula composite insulator's effect is with transmission line overhead suspension on the shaft tower, hang with excellent formula composite insulator when the needs hang on the shaft tower of transmission line, need adopt linkage to hang the insulator and put on the support of shaft tower, common insulator linkage is mostly ordinary screw rod at present, however adopt this kind of insulator linkage when the bad weather such as strong wind hail appears, can not play fine cushioning effect, consequently can cause the phenomenon that the insulator is pulled apart, the life of insulator has not only been shortened, and probably cause serious electric power accident, cause huge economic property loss or casualties.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a can play fine cushioning effect in order to solve above-mentioned not enough, prevent that the insulator is impaired, prolong the life of insulator, reduce the buffering formula insulator linkage for electric power that the electric power accident takes place.
The utility model discloses a solve above-mentioned technical problem and the technical solution who adopts as follows:
buffer type insulator linkage for electric power, it is including U-shaped bolt and mated buffering stop gear, mated buffering stop gear is including spring, stop nut, lock nut, ring baffle and mated positioning bolt respectively, mated buffering stop gear is about respectively and upper and lower symmetrical arrangement set up on the U-shaped bolt and be the location screw of row, the ring baffle cover is put on the U-shaped bolt, has seted up the shoulder hole on the ring baffle, mated positioning bolt wears to put in the shoulder hole to the spiral shell is put in the location screw, stop nut and lock nut are put on the U-shaped bolt soon respectively, and stop nut presss from both sides and puts between ring baffle and lock nut, a tip and the stop nut of spring contact.
The U-shaped bolt is made of stainless steel, and the spring is made of high-carbon alloy steel.
The utility model adopts the beneficial effect that above-mentioned technical solution can reach is: the springs of the paired buffering limiting mechanisms can play a good buffering role, so that the U-shaped bolt has certain allowance of moving up and down in the vertical direction, the impact on the insulator in severe weather such as strong wind is reduced, the insulator is prevented from being damaged or pulled off, the service life of the insulator is effectively prolonged, and the occurrence of electric power safety accidents is reduced.

fig. 2 is a partially enlarged schematic view of a portion a in fig. 1.
Detailed Description
As shown in fig. 1 and 2, the electric power buffer insulator suspension device comprises a U-bolt 1 and a pair of buffer limiting mechanisms, the paired buffer limiting mechanisms respectively comprise a spring 2, a limiting nut 3, a locking nut 4, an annular baffle 5 and paired positioning bolts 6, the paired buffer limiting mechanisms are respectively arranged in a left-right and up-down symmetrical manner, the U-shaped bolt 1 is provided with a row of positioning screw holes 7, the annular baffle 5 is sleeved on the U-shaped bolt 1, the annular baffle 5 is provided with a stepped hole 8, the paired positioning bolts 6 are penetrated in the stepped hole 8, and the limiting nut 3 and the locking nut 4 are respectively screwed on the U-shaped bolt 1, the limiting nut 3 is clamped between the annular baffle 5 and the locking nut 4, and one end part of the spring 2 is contacted with the limiting nut 3. U-shaped bolt 1 can select the stainless steel material to prevent it to take place the corrosion, spring 2 can select the high carbon alloy steel material, so that it has fine toughness and structural strength. When the device is used, the through hole 10 is formed in the support 9 of the power transmission line tower, the two end parts of the U-shaped bolt 1 firstly penetrate through the through hole 10, the paired buffering limiting mechanisms are respectively positioned on the two sides of the support 9, the other end parts of the paired buffering limiting mechanism springs 2 are abutted against the support 9, the device is fixed on the support 9 of the power transmission line tower, and then an insulator to be hung is hung on the lower part of the U-shaped bolt 1. The paired positioning bolts 6 are taken out from the stepped holes 8 and the positioning screw holes 7, and the position of the annular baffle 5 can be adjusted, so that the tightness degree of the spring 2 is adjusted, and the buffering degree of the insulator is adjusted.
