Embodiment Construction
[0027] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0028] Please also refer to Figure 1 to Figure 3 Now, a double-side pin-threading device for a power transmission line provided by the present invention will be described. The double-side pin-threading device for a transmission line includes: a support arm 1 , a first support member 2 and a second support member 3 . The first support member 2 is fixedly installed on one end of the support arm 1 along the vertical direction, and the lower end side wall of the first support member 2 is provided with a first positioning groove 201 for installing the closed end of th...

The invention provides a double-side pin penetrating device for a power transmission line, which belongs to the technical field of power transmission line maintenance equipment and comprises a supporting arm, a first supporting piece and a second supporting piece. The first supporting piece is fixedly installed at one end of the supporting arm in the vertical direction, and a first positioning groove used for installing the closed end of the R-type locking pin is formed in the side wall of the lower end of the first supporting piece. The upper end of the second supporting piece is provided with a sliding part in sliding fit with the first supporting piece, the second supporting piece has the freedom degree of moving in the vertical direction, the side wall of the lower end of the second supporting piece is provided with a second positioning groove used for installing the annular gasket, and the bottom face of the second positioning groove is provided with receding holes used for allowing the plug pin and the R-type locking pin to penetrate through. According to the double-side pin penetrating device for the power transmission line, the operation distance is prolonged, meanwhile, the R-shaped locking pin and the annular gasket can be assembled to the plug pin only by operating the supporting arm by a maintainer, and the assembling efficiency is greatly improved.
Description
technical field [0001] The invention belongs to the technical field of transmission line maintenance equipment, and more specifically relates to a double-side pin-threading device for a transmission line. Background technique [0002] There are many distribution points and a wide area of transmission lines, far away from cities and towns, the terrain is complex, and the natural environment is harsh. Power lines and tower accessories have been exposed to the wild for a long time, and are subject to continuous mechanical tension, electrical flashover, and material aging. Corrosion and other damage, if not repaired and replaced in time, the original small damage and defects may expand, eventually leading to serious accidents and large-scale power outages, resulting in great economic losses and serious social impacts. Therefore, it is necessary to conduct regular inspections on the transmission lines, keep abreast of the operation status of the transmission lines and the chang...
