Problems solved by technology
[0002] In the live or power failure inspection and maintenance work of the transmission line, the soft ladder is often used, and the soft ladder is connected to the lower side of the soft ladder. At present, only the soft ladder is used on the single line. It is very difficult to pass the spacer when the single line is used, and the labor intensity of the operators is high. It is labor-intensive and time-consuming, and there are unsafe factors. In order to reduce the labor intensity of operators and eliminate unsafe factors, and better adapt to different work needs, it is necessary to improve the soft ladder head

The invention relates to a flexible ladder head for both a single line and double lines for transmission maintenance. The flexible ladder head comprises two vertical columns, wherein the top end of each vertical column is rotatably connected with a suspension bracket; the rotation center lines of the suspension brackets coincide with the center lines of the vertical columns; each suspension bracket comprises a connecting rod and an n-shaped pulley support; the bottom end of one side of each pulley support is integrally connected with the corresponding connecting rod; the bottom end of each connecting rod is rotatably connected with the top end of the corresponding vertical column; a pulley is transversally mounted at the middle of each suspension bracket; a lower opening is formed in the lower side of each suspension bracket. According to the flexible ladder head for both the single line and double lines for transmission maintenance, provided by the invention, the flexible ladder head is made of aluminum alloy, thereby being light in weight and convenient to operate, and besides, various parameters conform to requirements, so that the characteristics of firmness, high bearing capacity and the like are further achieved.
Description
technical field [0001] The invention relates to a power transmission maintenance equipment. Background technique [0002] In the live or power failure maintenance work of the transmission line, the soft ladder is often used, and the soft ladder is connected to the lower side of the soft ladder. At present, only the soft ladder is used on the single line. It is very difficult to pass the spacer when the single line is used, and the labor intensity of the operators is high. It is labor-intensive and time-consuming, and there are unsafe factors. In order to reduce the labor intensity of operators, eliminate unsafe factors, and better adapt to different work needs, it is necessary to improve the ladder head. Contents of the invention [0003] The object of the present invention is to provide a single-double-wire soft ladder head for power transmission maintenance, which can reduce the labor intensity of operators working at high altitudes, and improve the safety factor and wor...
