Abstract

The invention relates to the technical field of R pin opening, in particular to an R pin opening tool for a disc type suspension insulator. The tool is used for opening an R pin. The tool comprises atool body, an insulator string element ball socket and a pin punching device. The R pin and the insulator string element ball socket are fixed in a tool body. The tool is characterized in that the pinpunching device is arranged at one end of the tool body; the R pin comprises a connecting end and an opened end, the connecting end is fixed in the tool body, and the opened end penetrates the insulator string element ball socket and stretches out of the insulator string element ball socket; the pin punching device comprises an opening knife and a compression connecting rod device connected to each other, the compression connecting rod device drives the opening knife to be close to or far away from the R pin, and the opening knife is used for opening the opened end. As the compression connecting rod device drives the opening knife to be close to or far away from the R pin and the opening knife opens the opened end, an effect of opening the R pin by the compression connecting rod device isachieved.

Description

technical field [0001] The invention relates to the technical field of R-pin opening, in particular to a R-pin opening tool for a disk-shaped suspension insulator. Background technique [0002] According to the national recommended standard for the opening size (V value) of the R pin for disc suspension insulators, the V value is between 8-15mm according to the different connection labels. However, due to the high strength of the R pin, it is very difficult to open the opening to 8-15mm, and the opening size of the existing manufacturing plants is generally within the range of 20-45mm. As the value of V increases, the R pin may be damaged or the R pin may fail when hoisting the insulator, which brings certain dangers. [0003] At present, with the application of large-tonnage insulators in UHV projects, if the opening size (V value) of the R pin is not properly controlled, it may bring operational risks to the transmission line. [0004] When opening, the opening angle of ...
