Portable signboard support of power transmission tower

Abstract

The invention discloses a portable signboard support for a power transmission tower. The portable signboard support comprises a left foldable telescopic bracket and a right foldable telescopic bracketwhich are arranged side by side. Each foldable telescopic bracket comprises a first bracket and a folding part; the first bracket is vertically arranged and is provided with a telescopic structure; the folding part comprises a second bracket, a third bracket and a fourth bracket; the first end of the second bracket is hinged with the upper end of the first bracket; the second end of the second bracket is hinged with the first end of the third bracket; the second end of the third bracket is hinged with the first end of the fourth bracket; in a fixed state with pedal rod angle steel, the secondbracket and the third bracket are in a horizontal state and clamped and fixed to the upper side and the lower side of the horizontal portion of the pedal rod angle steel, the fourth bracket is vertical and cooperates with the first bracket to be clamped and fixed to the front side and the rear side of the vertical portion of the pedal rod angle steel, the upper portion of the first bracket is connected with a first bolt, and the lower portion of the first bracket is connected with a second bolt. Erecting work can be completed only through two bolts, and the erecting efficiency is improved.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to an identification plate bracket. Background technique [0002] The signboard is an important symbol to reflect all aspects of the transmission line. Without a signboard or if the signboard is blurred, it will cause great safety hazards to the operation and maintenance of the transmission line. The existing signboard brackets are all operated by staff members on poles, and each time they need to carry a large number of bolts, nuts, gaskets and segmented brackets, which makes the whole installation and disassembly process complicated and requires the cooperation of multiple people . [0003] Therefore, it is necessary to design a signboard support, which has a simple structure, is easy to hang the signboard, and can hang the signboard firmly on the pedal to improve the work efficiency of hanging. Contents of the invention [0004] The technical problem to be solved by the pres...
