Abstract

The utility model belongs to a field of working tools for live line power maintenance and especially to an adjustable fixture for live line work of replacing a linear whole-string insulator for a four-split conductor. A fixture body (8) is distributed in a bilaterally symmetrical manner. The fixture body (8) is in a Z shape. A left part of the fixture body (8) and a right part of the fixture body (8) are connected through an adjustable tie rod (10). The adjustable tie rod (10) is equipped with an adjusting handle (11). A threaded fixing clamp (9) is fixed on a lower transverse face of the fixture body (8). A screw (5) penetrates through an end part of an upper transverse face of the fixture body (8) and is fixed by a ratchet wheel nut (7). The screw (5) connects with the insulation rod (4). The insulation rod (4) connects with a bilaterally symmetrical upper hook (3). Two lower hooks (2) are connected below the upper hook (3) in a bilaterally symmetrical manner. The adjustable fixture for live line work of replacing the linear whole-string insulator for the four-split conductor in the utility model is suitable for the live line work of replacing a linear string, a single whole-string or a double whole-string insulator of a 330 kV four-split conductor. The application range is wide. The human labor is saved. The working strength of workers is reduced. The adjustable fixture for live line work of replacing the linear whole-string insulator for the four-split conductor in the utility model has a simple structure and can be used conveniently and flexibly, thereby improving the working speed substantially.

Description

The adjustable jig of a kind of charged for replacement conductors on quad bundled straight line bunch of insulator
One, technical field:
The utility model belongs to electric power hotline maintenance power tool field, the adjustable jig of particularly a kind of charged for replacement conductors on quad bundled straight line bunch of insulator.
Two, background technology:
Along with expanding economy; Demand to electric power is increasing, and the construction of large capacity transmission circuit is also progressively accelerated, and conductors on quad bundled has appearred in the newly-built 330kV circuit of part; But power tool in the past can only be changed the double bundle conductor insulator; Or operation procedure is heavy, and complex process does not have ripe tool set for the upkeep operation of conductors on quad bundled.
Three, summary of the invention:
The utility model is the difficult problem to present 330kV circuit charged for replacement conductors on quad bundled straight line bunch of insulator, has proposed the adjustable jig of a kind of charged for replacement conductors on quad bundled straight line bunch of insulator.The utility model is to realize like this; The adjustable jig of a kind of charged for replacement conductors on quad bundled straight line bunch of insulator; It is characterized in that jig main body (8) left-right symmetric distributes, jig main body (8) is " Z " shape, and left and right sides jig main body (8) connects with adjustable drag link (10); Regulating handle (11) is arranged on the adjustable drag link (10); Be fixed with screw thread fixed card (9) on the following plane of structure of jig main body (8), a screw rod (5) and fixing with ratchet nut (7) is passed in the last plane of structure end of jig main body (8), and screw rod (5) links to each other with insulating bar (4); Insulating bar (4) links to each other with the symmetrical hook (3) of going up, and the following left-right symmetric of last hook (3) is connected with two lower draw-bars (2).The utility model is work like this; Regulate adjustable drag link (10) with regulating handle (11), adjust the distance between the two jig main bodys (8), with two jig main body (8) cross-arms on iron tower (6); And be fixed on the iron tower (6) with screw thread fixed card (9); Equipotential staff hangs over lead (1) in hook (3) and the lower draw-bar (2), rotating ratchet nut (7), and lead (1) is raised; The insulator that links to each other with lead (1) is lax, and equipotential staff is replaceable insulator.The utility model is applicable to the charged for replacement of 330kV conductors on quad bundled straight line string, single, double bunch of insulator, and applicable multiple iron tower cross-arm structure, applied range; Not only simplified operation process, and Billy saves manpower with strand mill lifting insulator, reduced personnel's labour intensity; Simple in structure; Easy to usely flexibly improved operating speed greatly, for the upkeep operation of conductors on quad bundled provides ripe tool set.
Four, description of drawings:
Fig. 1 is the utility model structural representation
Among the figure: 1, lead 2, lower draw-bar 3, on link up with 4, insulating bar 5, screw rod 6, iron tower 7, ratchet nut 8, jig main body 9, screw thread fixed card 10, adjustable drag link 11, regulating handle
Five, embodiment
Embodiment 1: the adjustable jig of a kind of charged for replacement conductors on quad bundled straight line bunch of insulator; Jig main body (8) left-right symmetric distributes; Jig main body (8) is " Z " shape; Left and right sides jig main body (8) connects with adjustable drag link (10), and regulating handle (11) is arranged on the adjustable drag link (10), is fixed with screw thread fixed card (9) on the following plane of structure of jig main body (8); A screw rod (5) and fixing with ratchet nut (7) is passed in the last plane of structure end of jig main body (8); Screw rod (5) links to each other with insulating bar (4), and insulating bar (4) links to each other with the symmetrical hook (3) of going up, and the following left-right symmetric of last hook (3) is connected with two lower draw-bars (2).
