The horizontal wire limit fixes part
Technical field
The present invention relates to the mechanical connection member, especially for the elastic connection element of power transmission line horizontal wire limit phase.
Background technology
Current, in the 10kV transmission line, lead is fixed on the porcelain rod with aluminum steel after being parcel layer of aluminum band.In implementation process, labour intensity is big, has more hazards, simultaneously, easily lead is caused damage.In application process, because lead fixed is on the porcelain rod of hard, under the less external force effect of strength such as wind, lead and porcelain rod contact position are easily because of the tired thigh or break of break; Under the bigger external force effect of strength, cause accidents such as the porcelain rod that fractures, damage electric pole easily; Be subjected under the external force effect at electric pole, break lead easily, the porcelain rod that fractures, in addition get an electric shock, accident such as fire.
Summary of the invention
The purpose of this invention is to provide a kind of horizontal wire limit and fix part, so that lead becomes elasticity to be connected with the porcelain clavate, reduce lead at the stress that porcelain rod place produces, prevent the broken string accident.
The object of the present invention is achieved like this: a kind of horizontal wire limit fixes part, mainly is made up of lead connecting elements and porcelain rod connecting elements; The lead connecting elements is: on the gum sleeve that is enclosed within on the lead axially open being arranged, the lead spring housing is on gum sleeve, and the left end of lead spring extends upward, and its straight up section form upper left spring and form upper left ring at upper left spring top, the right-hand member of lead spring extends upward, and its straight up section form upper right spring and form upper right ring at upper right spring top, upper left ring and upper right ring are by same axis arranged; Porcelain rod connecting elements is: the left end of porcelain rod spring extends downwards, and its straight down section form the lower-left spring and form the lower-left ring in lower-left spring bottom, the right-hand member of porcelain rod spring extends downwards, and its straight down section form the bottom right spring and form the bottom right ring in bottom right spring bottom, lower-left ring and bottom right ring are pressed same axis arranged; Also have upper left ring, upper right ring, lower-left ring and bottom right ring are worn the connector that extension links together.
Above-mentioned connector is made up of pin and plain cushion and split pin.
Compare with existing rigid the connection, beneficial effect of the present invention is:
1, lead is connected with the porcelain rod, and changes current rigid connection, lead and porcelain rod can move within the specific limits, reduce lead at the stress that porcelain rod place produces, the generation of the event that prevents from breaking.
2, move when electric pole is subjected to external force, the movement of porcelain rod and lead can reduce the risk that conductor cord disconnection, porcelain rod fracture; Or the reduction lead is subjected to big strength, the risk of fracture porcelain rod, electric pole.
3, be convenient to the application that the distribution line wire fracture is breaker device, prevent down that events such as rod disconnection cause the generation of accidents such as electric shock, fire.
4, the horizontal wire limit fixes part and is made up of porcelain rod spring, pin, lead spring and rubber sleeve, and pin is made up of pin, plain cushion and split pin.
5, porcelain rod spring, pin, lead spring are made by the steel material with certain toughness, can carry transmission line wire and the extraneous load that produces.
6, rubber sleeve is made by having certain flexible material, can absorb the vibrations of lead top, reduces the generation of stress.
The present invention is specially adapted to the connection of the limit phase of 10KV and following distribution network cathetus bar.

Embodiment
Fig. 1 illustrates, and the present invention mainly is made up of lead connecting elements and porcelain rod connecting elements; The lead connecting elements is: on the gum sleeve 1 that is enclosed within on the lead axially open being arranged, lead spring 2 is enclosed within above the gum sleeve 1, and the left end of lead spring extends upward, and its straight up section form upper left spring 2a and form upper left ring 2b at upper left spring top, the right-hand member of lead spring extends upward, and its straight up section form upper right spring 2c and form upper right ring 2d at upper right spring top, upper left ring 2b and upper right ring 2d press same axis arranged; Porcelain rod connecting elements is: the left end of porcelain rod spring 4 extends downwards, and its straight down section form lower-left spring 4a and form lower-left ring 4b in lower-left spring bottom, the right-hand member of porcelain rod spring extends downwards, and its straight down section form bottom right spring 4c and form bottom right ring 4d in bottom right spring bottom, lower-left ring 4b and bottom right ring 4d are by same axis arranged; Also have upper left ring 2b, upper right ring 2d, lower-left ring 4b and bottom right ring 4d are worn the connector (referring to Fig. 2, Fig. 3, Fig. 4) that extension links together.
Referring to Fig. 6, Fig. 7, connector is made up of pin 3 and plain cushion 3a and split pin 3b.Connecting elements also can adopt bolt or other existing bar formula connector.
Using method:
1), in the circuit erection process, the traction of strain section, firm finishing;
2), with suitable strength porcelain rod spring is inserted in the porcelain rod, and made the hanging hole end towards lead;
3), rubber sleeve is being inserted in lead with porcelain rod correspondence position;
4), after rubber sleeve is inserted in lead, the lead spring is spun on the rubber sleeve, and made the hanging hole end towards the porcelain rod, each spring hanging hole is corresponding;
5), pin is pierced into all spring hanging holes, an end porose at pin puts plain cushion, inserts split pin at last and gets final product.
