The upper end of the installation main frame 11 is connected to the push-pull mechanism 13, and the push-pull mechanism 13 is connected to the tower fixing part 2. The design of the push-pull mechanism 13 enables the installation main frame 11 to be adjusted when necessary, which makes it convenient to install and maintain the insulator string 3.

[0030] Among them, there are no less than two groups of mounting sub-frames 12, which can make the installation of the insulator string 3 more stable. It should be noted that the number of mounting sub-frames 12 can be set according to the actual length of the insulator string 3, and the specific number is not limited here. In addition, the mounting sub-frame 12 is not a closed design, but can be a snap-on type, bolt-fixed, etc., so that the insulator string 3 can be easily disassembled and assembled.

[0031] Reference Figures 2 - 4 The push-pull mechanism 13 includes a fixed guide rail 131, one end of the fixed guide rail 131 is fixedly connected to the iron tower fixing member 2, and a slider 132 is slidably connected to the inner side, the middle part of the slider 132 is rotatably connected to one side of the upper end of the mounting main frame 11 through a connecting rod 133, one side of the fixed guide rail 131 is provided with a fixed support 134 fixed to the iron tower fixing member 2, the fixed support 134 is provided with a gear 135, the middle part of the gear 135 is connected to a rotating column 136 that passes through the fixed support 134, one side of the fixed support 134 is provided with a rack seat 137, one side of the fixed guide rail 131 is installed with an electric push rod 138, and the push end of the electric push rod 138 is connected There is a rack 139, which is slidably arranged in the rack seat 137 and meshed with the gear 135.

The design of the push-pull mechanism 13 realizes efficient, accurate and stable push-pull operations through the combination of the electric push rod 138, the rack 139 and the gear 135, driving the bottom main installation frame 11 and the insulator string 3 to perform push-pull operations, so that the insulator string 3 can be pulled back to the tower attachment, which is convenient for workers to perform replacement operations.

[0032] Among them, a strip groove is provided at the bottom of the fixed guide rail 131, and the two sides of the groove are folded inward. The setting of the strip groove facilitates the sliding of the connecting rod 133.

Since one side of the upper part of the installation main frame 11 is connected to the slider 132 through the connecting rod one 133, and at the same time the slider 132 slides directionally in the fixed guide rail 131, and the installation main frame 11 is driven by the L-shaped pushing plate 1310, it will be as Figure 4 shown and expand, synchronously driving the insulator string 3 fixed to the bottom installation sub-frame 12 to turn, so that the insulator string 3 approaches the tower direction, facilitating the staff to carry out disassembly, replacement work. After the work is completed, the pushing end of the electric push rod 138 can be controlled to retract, the rack 139 retracts, driving the gear 135 to rotate counterclockwise, and at the same time the rotating column 136 rotates counterclockwise, driving the L-shaped pushing plate 1310 to turn, so that the installation main frame 11 drives the bottom insulator string 3 to return to Figure 1 and Figure 2 the state shown.

The upper end of the mounting seat two 79 is connected to the connecting pipe two 5. A spring 710 is arranged on the rod body of the expansion rod 78 placed inside the cylinder seat two 77. One end of the spring 710 abuts against the circular plate 703, and the other end abuts against one end inside the cylinder seat two 77. The provided tensioning and adjusting component 7 can provide the function of adjusting the tension, ensure the stability of the cable 6 during long-term use and reduce wear, making it safer.

[0037] Among them, an inner groove 701 is provided inside the first barrel base 72, and the threaded rod 75 passes through one end rod body of the threaded seat 73 and extends into the inner groove 701.

The first barrel base 72 is connected to the first mounting seat 71. The telescopic rod 78 can telescopically move inside the second barrel base 77. Since a spring 710 is provided on the rod body of the telescopic rod 78 placed inside the second barrel base 77, one end of the spring 710 abuts against the circular plate 703, and the other end abuts against one end inside the second barrel base 77. When the telescopic rod 78 telescopically moves inside the second barrel base 77, the elastic contraction of the spring 710 can perform tension adjustment between the telescopic rod 78 and the second barrel base 77, so as to elastically adjust the telescopic movement of the first connecting pipe 4 inside the second connecting pipe 5, ensuring the stability of the cable 6 during long-term use. And after rotating the adjusting wheel 74, the threaded rod 75 can be telescopically moved inside the threaded seat 73 through the thread, so as to adjust the compression degree of the spring 710, thereby realizing the adjustment of the tension degree. And the setting of the tension adjustment assembly 7 can synchronously adjust the tension degree of the cable during the pushing and pulling operation of the pushing and pulling mechanism 13, so as to ensure the stable pushing and pulling operation of the pushing and pulling mechanism 13.
