Abstract
A kind of improved double insulator string U-shaped screw suspension arrangement, including U-lag steel, suspension screw, U-lag steel and yoke plate connecting screw, four hole yoke plates, it is characterised in that：There are two suspension screws on U-lag steel top, and the pitch-row of two suspension screws is 80cm, and U-lag steel is connected by two suspension screws with shaft tower, and respectively there are two yoke plate connecting holes U-lag steel both sides；There is upper and lower two round on four hole yoke plates, upper row has two upper holes, two upper holes to wear the connection of yoke plate connecting screw after being aligned with the yoke plate connecting hole of U-lag steel；Row has two lower opening under four hole yoke plates, and two lower opening are connected by screw, right angle hanging plate, bulb ring with two insulator strings；Beneficial effect is：Only have single hangs to connect and should be connected for two yoke plate connecting screws on U-shaped screw and yoke plate, improve security reliability.
Description
Technical field
The present invention relates to a kind of electric transmission line isolator suspension arrangement, and in particular to a kind of improved double insulator string U-shaped
Screw suspension arrangement.
Background technology
With the raising of power supply reliability, transmission line of electricity is across sections such as high ferro, highway, important channels, to wire
The straight line pole hung as single hanging point needs to transform double hanging point as, improves the operation peace of transmission line of electricity and high ferro, highway etc.
Entirely.Insulator chain was often hung using U-shaped screw on transmission line of electricity in the past（As shown in Figure 1）, U-shaped screw and yoke plate only have one
Individual single hang connects, and the accident of going offline occurs once fracture occurs in single extension connection, jeopardizes the person and equipment safety.
The content of the invention
The purpose of the present invention provides a kind of improved double insulator string " u "-shaped screw exactly in order to overcome above mentioned problem
Suspension arrangement.
The technical solution adopted by the present invention is：
A kind of improved double insulator string U-shaped screw suspension arrangement, including U-lag steel, suspension screw, U-lag steel and yoke plate connect
Connect screw, four hole yoke plates, it is characterised in that：There are two suspension screws on U-lag steel top, and the pitch-row of two suspension screws is
80cm, U-lag steel are connected by two suspension screws with shaft tower, and respectively there are two yoke plate connecting holes U-lag steel both sides；Four hole yoke plates
On have upper and lower two round, upper row has two upper holes, two upper holes to wear yoke plate after be directed at the yoke plate connecting hole of U-lag steel to connect
Screw connection；Row has two lower opening under four hole yoke plates, and two lower opening pass through screw, right angle hanging plate, bulb ring and two insulator strings
Connection.
Compared with the prior art, the invention has the advantages that：Only have one single to hang connection this is U-shaped screw and yoke plate
Two yoke plate connecting screw connections, improve security reliability.

Icon explanation:
1. U-shaped screw；2. angle bar；3. U-shaped link；4. yoke plate；5. screw；6. right angle hanging plate；7. bulb ring；It is 8. exhausted
Edge；9. U-lag steel；10. hang screw；11. yoke plate connecting screw；12. four hole yoke plates.
Embodiment
Fig. 1 is the structural representation that prior art U-shaped screw is connected with yoke plate；Fig. 2 is Fig. 1 left view；In the past defeated
Double insulator string is often hung using U-shaped screw 1 in electric line, on the angle bar 2 installed in shaft tower of U-shaped screw 1, U-shaped screw 1
U-shaped link 3 is connected, U-shaped link 3 connects yoke plate 4, and U-shaped link 3 passes through screw 5, right angle hanging plate 6, bulb ring 7 and two insulation
Son 8 connects.Form single hangs between U-shaped screw 1 and U-shaped link 3, connection yoke plate 4 to connect, this singly hangs connection once occurring
The accident of going offline just occurs in fracture, jeopardizes the person and equipment safety.
Embodiment
Fig. 3 is the structural representation of the embodiment of the present invention；Fig. 4 is Fig. 3 left view；A kind of improved double strings of the invention are exhausted
Edge U-shaped screw suspension arrangement, including U-lag steel 9, suspension screw 10, yoke plate connecting screw 11, four hole yoke plates 12, its feature
It is：There are two suspension screws on the top of U-lag steel 9, and pitch-row and the former U-shaped screw 1 of two suspension screws are arranged on angle bar 2
Pitch-row is identical, and U-lag steel is connected by two suspension screws 10 with the angle bar 2 on shaft tower, and respectively there are two connection the both sides of U-lag steel 9
Plate connecting hole；There is upper and lower two round on four hole yoke plates 12, upper row there are two upper holes, and two upper holes and the yoke plate of U-lag steel 9 connect
Wear yoke plate connecting screw 11 after connecing hole alignment and connect；Row has two lower opening under four hole yoke plates, and two lower opening pass through screw 5, right angle
Hanging plate 6, bulb ring 7 are connected with two insulators 8.Conventional U-shaped screw and yoke plate are only had a single extension connection to change by the present invention
Connected for two yoke plate connecting screws 11, improve security reliability, the pitch-row of two suspension screws is installed with former U-shaped screw 1
Pitch-row on angle bar 2 is identical, easily can hang connection to prior art list and transform.
