Abstract

A kind of preformed wire jumper drainage gold utensil, comprised fluid, preformed deflation bar and clip, cross fluid upper and lower end face and be respectively arranged with circular groove, crossing fluid is connected with the main traverse line in overhead transmission line by the groove of upper end, groove by lower end is connected with the drainage thread in overhead transmission line, and preformed deflation bar was wrapped in the outside of fluid, main traverse line and drainage thread assembly and was fixed by clip. The present invention is simple in structure, and cost is low, in transmission line of electricity and traction payingoff construction, is suitable for common strain clamp and is connected with main traverse line, and strain clamp need not, with drainage plate and conduction wire clamp, can directly draw main traverse line and cross coaster, direct hanging wire after unwrapping wire. This version can be avoided the repeatedly crimping of drawing head and conduction wire clamp, and reduces the loss of wire and drawing head or net, reduces difficulty of construction, improves efficiency of construction.

Description

A kind of preformed wire jumper drainage gold utensil
Technical field
The utility model relates to a kind of Poling Construction and wire jumper drainage gold utensil used for transmission line, particularly a kind of preformed wire jumper drainage gold utensil connecting with overcurrent effect that plays between main traverse line and drainage thread.
Background technology
In traditional aerial condutor traction payingoff construction, adopt special drawing head or bracing wire net to draw wire, through too much organizing releasing pulley, arrive after the terminal of strain section, excision drawing head or a section lead, after carrying out again the crimping of strain clamp and main traverse line and hanging wire, drainage thread with after conduction wire clamp crimping, be connected with the drainage plate bolted on strain clamp.
Drainage plate shape on strain clamp is as a wing, in unwrapping wire, must adopt special drawing head or bracing wire net to draw wire and cross coaster, cross coaster unwrapping wire therefore cannot adopt strain clamp directly to draw wire, drawing head and conduction wire clamp etc. must carry out repeatedly crimping operation simultaneously, also can cause the loss of drawing head or net, wire, and the installation site of conduction wire clamp is unadjustable.
In addition, in aerial condutor transmission line of electricity, strain clamp and conduction wire clamp be connected to bolt type of attachment, conduction wire clamp exist repeatedly crimping and conduction wire clamp installation site nonadjustable problem same with drainage thread.
Utility model content
For the defect existing in prior art, the utility model provides a kind of preformed wire jumper drainage gold utensil, can adopt strain clamp directly to draw main traverse line and cross coaster unwrapping wire.
Concrete technical scheme is: a kind of preformed wire jumper drainage gold utensil, comprised fluid, preformed deflation bar and clip, cross fluid upper and lower end face and be respectively arranged with circular groove, crossing fluid is connected with the main traverse line in overhead transmission line by the groove of upper end, groove by lower end is connected with the drainage thread in overhead transmission line, and preformed deflation bar was wrapped in the outside of fluid, main traverse line and drainage thread assembly and was fixed by clip.
Described preformed deflation bar intermediate portion was wrapped in the outside of fluid, main traverse line and drainage thread assembly, and its two ends are wrapped on main traverse line or drainage thread and by little clip and fix.
Described preformed deflation bar is aluminum-alloy wire or aluminum cald steel wire.
Described fluid material therefor is excessively aluminium.
The utility model is simple in structure, cost is low, adopt preformed armor rods hold with a firm grip " wire-mistake fluid-wire ", there is stress dispersion, do not damage twisted wire, the feature conducting electricity very well, and install, dismantle simple, can be fast, install at the scene by hand easily, installation quality is easy to ensure, naked eyes can be tested; In transmission line of electricity and traction payingoff construction, be suitable for common strain clamp and be connected with main traverse line, strain clamp need not, with drainage plate and conduction wire clamp, can directly draw main traverse line and cross coaster, direct hanging wire after unwrapping wire. This version can be avoided the repeatedly crimping of drawing head and conduction wire clamp, and reduces the loss of wire and drawing head or net, reduces difficulty of construction, improves efficiency of construction.
Brief description of the drawings
Fig. 1 is the utility model structural representation;
Fig. 2 be in Fig. 1 A-A to cutaway view;
Fig. 3 crosses fluidic structures schematic diagram in the utility model;
Fig. 4 is that the utility model uses status architecture schematic diagram.
Detailed description of the invention
As shown in Figure 1, Figure 2 and Figure 3, a kind of preformed wire jumper drainage gold utensil, comprised fluid 1, preformed deflation bar 2 and clip 3, clip 3 is common clip, cross fluid 1 upper and lower end face and be respectively arranged with circular groove 4 and groove 5, cross fluid 1 and be connected with the main traverse line 6 in overhead transmission line by the groove 4 of upper end, the circular arc place radius of a circle of circular groove 4 is identical with the radius of main traverse line 6, makes fluid 1 tightr with coordinating of main traverse line 6; Cross fluid 1 and be connected with the drainage thread 7 in overhead transmission line by the groove 5 of lower end, the circular arc place radius of a circle of circular groove 5 is identical with the radius of drainage thread 7, makes fluid 1 tightr with coordinating of drainage thread 7; Preformed deflation bar 2 mid portions were wrapped in the outside of fluid 1, main traverse line 6 and drainage thread 7 assemblys and were fixed by clip 3, its two ends are wrapped on main traverse line 6 or drainage thread 7 and by lesser calorie hoop 9 and fix, and make the connection of fluid 1, main traverse line 6 and drainage thread 7 more fastening.
As shown in Figure 4, main traverse line 6 ends are connected and just can directly not draw main traverse line 6 after the strain clamp 8 with drainage plate and cross coasters and carry out unwrapping wire, direct hanging wire after unwrapping wire, can adopt multistage to cross fluid 1 according to on-site actual situations and connect.
Preformed deflation bar 2 is aluminum-alloy wire or aluminum cald steel wire, it has certain pliability and has good electric conductivity, before using, preformed deflation bar 2 is prefabricated into helical structure, the hollow space longitudinal section of its helical structure is hemispherical or duckbill, reduce the internal stress in use producing because of deformation, make the pulley of coaster more easily pass through simultaneously.
Crossing fluid 1 material therefor is aluminium, and its lighter weight and have good electric conductivity flows on drainage thread 7 electric current on main traverse line 6.
