Description
Technical field
The utility model belongs to electric railway transmission system technical field, and in particular to a kind of electrification railway contact net
With high-strength composite railway curved boom.
Background technology
Since the trend of China railways has more than half part run in the tunnel on high and steep mountains, subway 90 percent exists
Underground is run, dark in tunnel, moist, ventilation effect is poor, hole interior air-flow is non-constant in vehicle passes through, it is filthy seriously etc.,
Corrosion easily occurs under such circumstances for a long time for equipment and netware, and the resistance to filthy ability of insulator declines.In China and Europe
Country, electrification railway contact net be all ceramic insulator or composite insulator and the collocation of aluminium alloy steel pipe structure.
Its is complicated, and cost is high, and difficulty of construction is big.And because aluminium alloy steel pipe is conductive material, effective insulation cannot be provided
Distance.Flashover trip accident happens occasionally caused by dielectric level declines, these are all that the maximum securely and reliably powered is chosen
War.Directly affect the safe and punctual operation of the railway system.
Invention content
In order to overcome the above-mentioned deficiencies of the prior art, the purpose of this utility model is to provide a kind of electrification railway contact net
With high-strength composite railway curved boom, aluminum alloy materials are changed to glass-reinforced plastic material.So that contact net partial appearance is more succinct,
And glass-reinforced plastic material is used, to effectively increase insulation distance.
To achieve the goals above, the technical solution adopted in the utility model is：
A kind of electrification railway contact net high-strength composite railway curved boom, including column, level insulation arm pass through bracket
Upper bed-plate connects column, and oblique insulation arm connects column by bracket lower bottom base, and the oblique insulation arm other end is connected by bushing double eye
Level insulation arm connects level insulation arm among oblique insulation arm by support, and by supporting the support pipe clamp A at both ends to fix,
Oblique insulation arm connects positioning pipe by positioning support tube, and is fixed by support pipe clamp B, and positioning pipe one end is connected oblique by locating ring
Insulation arm, positioning pipe connect rectangular locator by positioning support, and level insulation arm is equipped with Messenger Wire base, level insulation arm one
End is equipped with 60 pipe caps of φ, and positioning pipe one end is equipped with 48 pipe caps of φ.
The level insulation arm and oblique insulation arm use insulating materials.
Fiberglass can be used in the insulating materials.
The utility model has the beneficial effects that：
Aluminum alloy materials are changed to glass-reinforced plastic material by the utility model.So that contact net partial appearance is more succinct, and
And glass-reinforced plastic material is used, to effectively increase insulation distance.

Specific implementation mode
The utility model is further discussed below below in conjunction with attached drawing.
As shown in Figure 1, a kind of electrification railway contact net high-strength composite railway curved boom, including column 1, feature exists
In level insulation arm 4 connects column 1 by bracket upper bed-plate 2, and oblique insulation arm 9 connects column 1 by bracket lower bottom base 16, tiltedly
9 other end of insulation arm connects level insulation arm 4 by bushing double eye 5, passes through 8 connection level insulation of support among oblique insulation arm 9
Arm 4, and by supporting the support pipe clamp A3 at 8 both ends to fix, oblique insulation arm 9 connects positioning pipe 12 by positioning support tube 10, and
It is fixed by support pipe clamp B13,12 one end of positioning pipe connects oblique insulation arm 9 by locating ring 11, and positioning pipe 12 passes through positioning support
14 connection rectangular locators 15, level insulation arm 4 are equipped with Messenger Wire base 6, and 4 one end of level insulation arm is equipped with 60 pipe caps 7 of φ, fixed
Position 12 one end of pipe is equipped with 48 pipe caps 17 of φ.
The level insulation arm 4 and oblique insulation arm 9 are fiberglass.
