Abstract
The utility model relates to an insulated locating rod, which comprises a single-tap hardware and a pipe cap. A blind hole is arranged at the connecting end of the single-tap hardware. One end of an insulated rod is inserted into the blind hole and connected with the single-tab hardware. In addition, the other end is inserted into a thru hole of a retainer for fixing the hardware and connected with the retainer fixing hardware. The joint of the insulated rod with the retainer fixing hardware and single-tap hardware has a convex and concave face. The insulated rod is provided with a layer of polyfluortetraethylene, which has excellent hydrophobic nature, electric corrosion resistance and superior anti-tracking marks. Therefore, the insulated rod has better hydrophobic nature, waterproof and dampproof performance and high insulting capacity. Rupturing load of the connected insulated rod can exceed 120kN to avoid locating rod fall-off. Length of the insulated rod can achieve over 500mm, thus exceeding 250mm creepage distance and decreasing the length of the retainer fixing hardware and reducing the overall weight of the utility model.
Description
Technical field:
The utility model relates to contact system accessory in electrified railway or the urban duct traffic system, particularly a kind of insulation radius stay.
Background technology:
The insulation radius stay of line of Shanghai Underground and the production of No. two line use Siemens Companys, its structure as shown in Figure 1 to Figure 3, this radius stay connects gold utensil 2 by full skirt shape insulator 3, monaural and connecting rod 1 constitutes, wherein full skirt shape insulator 3 is made for epoxide resin material, connecting rod 1 is a stainless steel tube, and connecting rod 1 rear end is with pipe cap 5.Each embedded copper nut 4,7 of insulator 3 two ends, monaural connection gold utensil 2 ends are shaped on bolt and are screwed into copper nut 4 and are connected with insulator 3; Connecting rod 1 end is shaped on negative thread, and bolt 6 two ends connect the negative thread of copper nut 7 and connecting rod 1 respectively, and connecting rod 1 and insulator 3 are connected.The insulation radius stay weight of said structure is heavier, and is cumbersome during installation; During locomotive operation, the insulation radius stay is collided and is vibrated, and after the long-term work, becoming flexible, coming off appears in bolt and bolt 6 that monaural connects gold utensil 2, has potential safety hazard, needs regular maintaining; In addition, full skirt shape insulator 3 is not easy to clean, and insulating power are not very good.
The utility model content:
The purpose of this utility model provide a kind of easy for installation, produce simple, low cost of manufacture,, safe and reliable, non-maintaining a kind of insulation radius stay.
Scheme of the present utility model is: comprise that monaural connects gold utensil and pipe cap, monaural connects the gold utensil coupling end and is shaped on blind hole, insulation rod one end stretches into blind hole and is connected gold utensil with monaural and withholds connection, the other end stretch into supporter fixedly gold utensil through hole and supporter fixedly gold utensil withhold and be connected, insulation rod and supporter fixedly gold utensil, the monaural junction that is connected gold utensil are male and fomale(M﹠F) and engage, and the insulation rod outside face covers polytetrafluoroethylene floor.
Insulation rod is made cylinder by the fiber reinforced epoxy resin drawable material, and length is 500-1500mm, and creep distance is 350-1200mm.
The utility model has the advantages that: good, the anti-galvanic corrosion of the outer field polytetrafluoroethylene floor hydrophobic of insulation rod damage property and anti-creepage trace are superior, and the insulation radius stay is difficult for knot water, and waterproof and dampproof performance and insulating power are better.Insulation rod and supporter fixedly gold utensil, monaural are connected gold utensil and withhold connection, and the fail in tension load reaches more than the 120kN, and the insulation radius stay can not come off.Insulation rod can be made into more than the 500mm, exceeds original 250mm creep distance; Supporter fixedly gold utensil length reduces, and overall weight alleviates.

The specific embodiment:
With reference to Fig. 4 to Fig. 7, insulation rod 12 of the present utility model adopts the fiber reinforced epoxy resin drawable material to make cylinder, monaural connects gold utensil 11 coupling ends and makes blind hole, insulation rod 12 inserts blind hole, and with the machine of withholding insulation rod 12 is connected gold utensil 11 fastenings with monaural and connects, the supporter that insulation rod 12 other ends stretch into stainless steel tube is gold utensil 14 fixedly, also with withhold machine with insulation rod 12 and supporter fixedly gold utensil 14 fastenings be connected.Insulation rod 12 is connected gold utensil 11, supporter and fixedly forms male and fomale(M﹠F) in the junction of gold utensil 14 with monaural, increased friction force and grip force.Exposed insulation rod 12 skins are surrounded by one deck hot shortness polytetrafluoroethylene floor 13, and its hydrophobic nature has reached the HC1 level.Supporter fixedly gold utensil 14 is not held and is with pipe cap 15.Insulation rod 12 length are 1000mm, and the length that monaural connects gold utensil 11 is 130mm, and supporter fixedly gold utensil 14 length is 200mm, and the creep distance of radius stay reaches 680mm, and the fail in tension load reaches more than the 120kN, surpasses the 50kN that requires.
The utility model employing is withheld machine and is withheld connection, and production technology is simple, cost is low, dependable performance; Polytetrafluoroethylene floor 13 hydrophobics are good, waterproof and dampproof, again cleaning easily; Creep distance is 680mm, is far longer than original 250mm, and insulating power are superior.Supporter fixedly gold utensil 14 shortens, and the weight saving of insulation radius stay is original half, the convenient installation.
