Anti-climbing stair for high-voltage electric wire tower

Abstract

The invention provides an anti-climbing stair for a high-voltage electric wire tower and relates to a stair. A board shaped like a Chinese character 'Tu' (9) is connected with the face at the lower part of a connection flange (3) at the lowermost part of the high-voltage electric wire tower; the lower part of the convex position of the board shaped like the Chinese character 'Tu' is fixedly connected with the upper end of a channel steel jacket (5); the lower end of the channel jacket is fixedly connected with a forward bending part at the lower end of a back supporting board (10); the both sides of the face at the front part of the back supporting board are movably connected with the inner ends of a plurality of steel roll stairs (6) through a plurality of pin shafts (14); the steel roll stairs are located at a horizontal position, and limiting convex blocks (12) are respectively arranged at each upper part of the steel roll stairs, which is tightly adhered to an upward bending rod (13); splicing rods (11) are respectively arranged at the back part of a connecting rod (7) corresponding to the upper part of the other end of each upward bending rod. The foldable stair arranged at the lower part of the high-voltage electric wire tower disclosed by the invention can be used for effectively preventing children or suicides from climbing the high-voltage electric wire tower.

Description

【Technical field】 [0001] The invention relates to a ladder, in particular to a high-voltage wire tower anti-climbing ladder. 【Background technique】 [0002] As we all know, high-voltage power towers are the main support for electric power transmission cables and can be seen everywhere. The current high-voltage power towers are divided into angle steel structures and hexagonal thick steel column structures. Among them, angle steel structures are mostly used in the field, and urban areas are gradually changed to hexagonal thick steel column structures. High-voltage power towers; because most of the cables are made of copper or aluminum, they have high economic value and have become one of the targets of thieves. Cases of cable theft occur from time to time; Some people choose the high-voltage power tower as a place to commit suicide because of wages or a moment of inability to think about it. There are also children who climb the high-voltage power tower for the purpose of fun...

[0002] As we all know, high-voltage electric towers are the main support for electric power transmission cables, which can be seen everywhere. The current high-voltage electric towers are divided into angle steel structures and hexagonal thick steel column structures. Among them, angle steel structures are mostly used in the field, and urban areas are gradually changed to hexagonal thick steel column structures. High-voltage power towers; because most of the cables are made of copper or aluminum, they have high economic value and have become one of the targets of thieves. Cases of cable theft occur from time to time; Some people choose high-voltage power towers as the place to commit suicide because of wages or can’t think about it for a while, and some children climb high-voltage power towers for the purpose of fun, causing personal casualties; the above-mentioned reasons are mainly because there are no safety protection devices on high-voltage power towers; in order to prevent Climbing high-voltage wire towers, there are eye-catching warning signs such as "No Climbing, High Voltage Danger" on the ladders of high-voltage wire towers, so as to prevent or remind people not to climb, so as not to cause personal injury, because children or suicides are harmful to this The cognitive ability of such warnings is poor or ignored, and there have been many personal injury accidents in which children or suicides climbed high-voltage power towers. It can be seen that the setting effect of simple warning signs is not ideal
