Description

Technical Field

[0001] The utility model relates to the technical field of electric power construction, in particular to a high-voltage transmission iron tower anti-fall safety isolation device. Background Art

[0002] The emergence of anti-fall safety isolation devices for high-voltage transmission towers is to ensure the safety of construction workers when working at high altitudes. Since high-voltage transmission towers are usually located at higher positions, construction workers face great risks of falling during maintenance and operations. In order to prevent such accidents from happening, a special anti-fall safety isolation device is designed. It comprehensively considers the various potential risks of construction workers when working at high altitudes. Through physical isolation, protective equipment and safety measures, the possibility of falling accidents is minimized and the personal safety of construction workers is guaranteed.

[0003] The wires of high-voltage transmission towers are arranged in multiple layers. During traditional maintenance, objects falling from above during cross-operation may injure construction workers below. During the operation, construction workers stand on the tower and hang safety ropes on the tower, which restricts operation and reduces efficiency. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model provides a high fence and a low fence. The high fence is on the outside to prevent construction workers from falling, and the low fence is on the inside to facilitate construction workers to perform maintenance work on the high-voltage transmission tower. The galvanized steel pipe has a strong corrosion resistance. By providing a slide rail, a limit block, a pulley, a safety door, a locking hole and a locking pin, the pulley moves on the slide rail to control the switch of the safety door. The limit block can prevent the safety door from sliding to the same side when closed, causing the opening to leak and cause danger. After the construction worker enters the device, he can close the safety door and insert the locking pin into the locking hole. To prevent the safety door from opening, the upper and lower floors can be separated by setting up a floor, which prevents objects from falling from above and injuring the construction workers below during cross-operation, and improves operational flexibility and efficiency. By setting up anti-slip strips, the metal floor will become slippery after rain and snow. The anti-slip strips can increase the friction of the floor in rainy and snowy weather to prevent construction workers from slipping and falling. By setting up a ladder, construction workers can move between the two floors. By setting up a safety frame, when the safety door needs to be opened to lift objects, the safety rope can be hung on the safety frame to provide protection to prevent construction workers from falling during lifting.
