Abstract

The utility model discloses an aerodynamic insulator replacing tool for steel tower side phase cross arms, which comprises clamping devices in split structures. A pin hole, a half-long round hole and an installing through hole are arranged on the upper left side of a single clamping device. The clamping devices are made of aerospace aluminum manganese alloy materials, and installed on two sides of aerodynamic insulator strings on the cross arms horizontally symmetrically according to the size of the disc diameter of an aerodynamic insulator. On the existing running lines, the replacing tool can perform live-line replacement of the aerodynamic insulator strings without changing tower structures, thereby guaranteeing normal power supply of power transmission lines.

Description

The aerodynamic type insulator that is used for iron tower limit phase cross-arm is changed instrument
Technical field
The utility model relates to transmission line, is specifically related to the replacing instrument of aerodynamic type insulator on the transmission line.
Background technology
After freezing, string caused line tripping because dangle at the insulator of installing on the 220KV transmission line in the past easily; So behind ice damage several years ago; The falsification of dangling of insulator on the 220KV transmission line is guaranteed the normal power supply of transmission line for the aerodynamic type insulator, but the jig main body of original replacing insulator is an overall structure, its installation dimension is nonadjustable; And the disk track of aerodynamic type insulator is bigger; Original jig can not use, can only have a power failure at present to change the aerodynamic type insulator, brings negative effect for normal operation of circuit and reliability.
The utility model content
The utility model provides the replacing jig of a kind of minute body structure, adopts the replacing of the method completion aerodynamic type insulator string of live line working, does not influence the normal power supply of transmission line.
The utility model comprises jig, and jig is for dividing body structure, and left-right symmetric is installed on the both sides of iron tower limit phase cross-arm, and the upper left side of single jig offers pin hole, half slotted hole and installation through holes, and the lower right side offers the shop bolt hole.
The material of said jig is the space flight alumal, rated load 25kN, and static test load 62.5kN, coefficient of safety is not less than 2.5.
The jig of the utility model adopts space flight alumal material manufacture for dividing body structure; Size according to aerodynamic type insulator disk track; Left-right symmetric is installed in the both sides of aerodynamic type insulator string on the cross-arm; On the circuit of existing operation, do not change just ability charged for replacement aerodynamic type insulator string of tower structure, guarantee the normal power supply of transmission line.
Description of drawings
Fig. 1 is the operating state assembling sketch map of the utility model.
Fig. 2 looks sketch map for the master of the jig of the utility model.
Fig. 3 looks sketch map for the left side of Fig. 2.
Embodiment
Like Fig. 1, Fig. 2 and shown in Figure 3, the utility model is installed on the iron tower limit phase cross-arm 1, comprises jig 2, screw mandrel 3, insulated tension pole 6 and links up with 7, and the lower end of screw mandrel 3 connects insulated tension pole 6, the lower end coupling hook 7 of insulated tension pole 6; During installation; Earlier jig 2 is installed on the iron tower limit phase cross-arm 1 through pin rod 25 left-right symmetric of passing dowel hole 24, the position is about aerodynamic type insulator string 5 symmetries, then with screw mandrel 3, insulated tension pole 6 with link up with 7 assembly parts and be installed in the installation through holes 23 on the jig 2; Tighten the pin 26 that passes pin hole 21 and clamp screw mandrel 3; Be processed with bayonet socket on the screw mandrel 3, be stuck in half slotted hole 22, be used to limit rotating in a circumferential direction of screw mandrel 3; The length that spanner 4 on the rotary screw 3 is regulated screw mandrel 3 makes hook 7 catch on lead 8.
The upper end of aerodynamic type insulator string 5 is through bulb 9 and bowl 10 and spring pivot 11 is connected with cross-arm 1 and fixing, and the lower end is connected with lead 8 to reach through bulb 9 and bowl 10 and spring pivot 11 to be fixed.When changing aerodynamic type insulator string 5; Extract its spring pivot 11 at two ends up and down earlier; Spanner 4 on the rotary screw 3 up moves screw mandrel 3 then; Drive insulated tension pole 6 and move upward with hook 7, hook 7 catches on lead 8 upwards, thereby makes the bowl that is installed on the wire clamp 12 10 upwards; Again aerodynamic type insulator string 5 is extracted from the side breach of bowl 10 and changed bad aerodynamic type insulator string 5, new aerodynamic type insulator string 5 is loaded onto by the anti-order of pulling down got final product then.
