Problems solved by technology

This method is time-consuming and labor-intensive, and it is easy to cause high-altitude objects to fall
pose a great safety hazard
And because the diameter of all porcelain insulators with a voltage level of ±660kV is large, and the weight of a single insulator is about 30 kg, it is impossible for a single person to lift it to the string

Embodiment Construction

[0012] as attached figure 1 As shown, the present invention includes a left fixed snap ring 2 and a right fixed snap ring 3 connected by a fixing rod 1, and a pulley connected with the left fixed snap ring 2 and the right fixed snap ring 3 by the left bracket 4 and the right bracket 5 respectively. The hanging ring frame 6, the pulley hanging ring frame 6 is provided with a hanging hole 9.

[0013] The left fixing snap ring 2 of the present invention is composed of two upper and lower half rings hinged at one end, and the other ends of the upper and lower half rings are provided with a left locking card 7, and the right fixing snap ring 3 is hinged at one end. The upper and lower half rings are connected, and the other ends of the upper and lower half rings are provided with a right locking card 8 .

[0014] The present invention relies on the parallel arrangement of double-string insulators, makes full use of the inherent conditions of the equipment itself, utilizes the insu...

Abstract

The invention relates to a cradle for replacing a porcelain insulator of a + / -660kV strain tower of a power system. The cradle comprises a left fixed snap ring, a right fixed snap ring and a pulley hanging ring rack, wherein the left fixed snap ring is connected with the right fixed snap ring through a fixing rod, the pulley hanging ring rack is respectively connected with the left fixed snap ring and the right fixed snap ring through a left bracket and a right bracket, and the pulley hanging ring rack is provided with a hanging hole. According to the cradle for replacing the porcelain insulator of the + / -660kV strain tower disclosed by the invention, the working hours for replacing a single porcelain insulator of the strain tower are effectively reduced, the labor intensity is reduced, and the safety level of overhead working personnel and ground cooperative personnel is improved.

Description

technical field [0001] The invention relates to a replacement porcelain insulator hanger for a ±660kV tensile tower of a power system. Background technique [0002] All tension towers of ±660kV Yindong Line are all made of porcelain insulators. When the porcelain insulators are damaged and have zero value, they must be replaced. The transfer pulley is fixed on the insulator string, and the ground cooperating personnel transfer the single-piece porcelain insulator to the lower edge of the porcelain insulator tensile string with a transfer rope. Raised above the string of porcelain insulators. This method is time-consuming and labor-intensive, and it is easy to cause high-altitude objects to fall. pose a great safety hazard. And due to the large diameter of all porcelain insulators in the ±660kV voltage level, and the weight of a single insulator is about 30 kg, it is impossible for a single person to lift it to the string. SUMMARY OF THE INVENTION [0003] The technical...
