Summary of the invention
The task of the utility model provides a kind of device that overhead ground wire uses of on charged high-tension line, changing, and, safe in utilization, manipulate easy, simple in structure.
The technical scheme of the utility model is following:
A kind of device of on charged high-tension line, changing the overhead ground wire use includes with flat-shaped first arc hook 2, with flat-shaped second arc hook 8, and; The arc small end of first arc hook 2 and the arc small end of second arc hook 8 fit afterwards with bearing pin 3 be linked together; Be characterized in that said bearing pin 3 is a hollow shaft, and; In the axis hole of bearing pin 3, be provided with the positioning hanger 4 of spring shape, two end axial surface that the termination is stretched out bearing pin 3 respectively of its positioning hanger 4.
Simultaneously; Link up with at the arc small end of first arc hook 2 and second arc between the binding face of 8 arc small end and be provided with packing ring 13; Its packing ring 13 is sleeved on the bearing pin 3; Simultaneously, on the bearing pin 3 that non-binding face one side of its arc small end is exposed, be respectively arranged with first limiting gasket 11, second limiting gasket 12.
Simultaneously, on the crooked segmental arc of the big end of arc of first arc hook, 2, second arc hook 8, be respectively arranged with slip pearl 9.
Simultaneously, be respectively arranged with side guard plate 1 in the inboard and the outside of the crooked segmental arc of the big end of arc of first arc hook, 2, second arc hook 8; Its side guard plate 1 can be protected the pearl body of slip pearl 9.
In technique scheme, the first annular hook, 2, second arc hook 8 is the outsourcing standard component.Its packing ring 13 is sleeved on the bearing pin 3, the mode of first limiting gasket 11, the welding of second limiting gasket, 12 usefulness is fixed on the bearing pin 3.Replacements such as its first limiting gasket 11, the second limiting gasket 12 also available outsourcing standard component retainer or retaining ring for shaft shoulder.
During use, the method for between two adjacent iron towers, changing ground wire is: prepare several identical the utility model devices and pull rope and new ground wire earlier.
The first step:
Earlier the keying condom 6 of first the utility model device is opened, and pressed keying depression bar 5, make 2 one-tenth openings of its first arc hook, the hook that will open subsequently is connected on the once visited place line that needs between two adjacent iron towers to change; Simultaneously, after keying depression bar 5 resets, close its condom 6;
Subsequently, again one section of the front end of pull rope is wrapped on two terminations of spring shape of the end axial surface of stretching out bearing pin 3 of positioning hanger 4;
Simultaneously, again one section of the front end of new ground wire is fixedly set in the arc hook 8.
Second step:
The keying condom 6 of second the utility model device is opened, and pressed keying depression bar 5, make 2 one-tenth openings of its arc hook, the hook that will open subsequently is connected on the line of foregoing once visited place; And, after keying depression bar 5 resets, close its condom 6;
Subsequently, open and open and close condom 6, make 8 one-tenths openings of second arc hook, and the length of selection pull rope, simultaneously this section pull rope is wound on two terminations of spring shape of positioning hanger 4; Simultaneously, also will place in second arc hook 8 with the new ground wire of pull rope respective length; After keying depression bar 5 resets, close its condom 6.
Subsequently; Repeat the content in second step noted earlier; And affect its pull rope to move to another iron tower direction from an iron tower, and can its utility model constantly be installed on the line of foregoing once visited place, also its new ground wire constantly is arranged at two line belows, once visited place between the iron tower simultaneously; Remove the once visited place line subsequently, connect new ground wire, and the once visited place line is withdrawn from.
In the above-mentioned operation process of between two adjacent iron towers, changing ground wire, second arc hook 8 can prevent and avoid after its ground wire downwarp to cross electrical phenomena with operating other high-tension bus-bar touching back produces effectively; Need not consider in this operation process with control ground wire downwarp after other safety problems that can occur.Its operating type is simple and convenient.
The utility model constitutes notched version after also can omitting or remove depression bar 5, condom 6 parts, and practical application in engineering construction; During application, economize the content of operation that removes depression bar 5, condom 6 and get final product.
The beneficial effect of the utility model is following: owing to adopt technique scheme, realized not having a power failure change the ground wire operation its safe and reliable the time, also manipulate easy, simple in structure.
