Reliable single-pipe tower with anti-falling function

Abstract

The invention relates to a reliable single-pipe tower with an anti-falling function. The reliable single-pipe tower with the anti-falling function comprises a base, a tower body, a lighting conductor, a lifting device and two antenna devices. The lifting device comprises a working platform, a driving device, a rotary shaft and two conveying units. Each transmission unit comprises second rolling wheels and a supporting plate. The driving device comprises a transmission unit, two handles and two anti-falling units. Each anti-falling unit comprises a hinged unit, a rotary rod, a limiting frame, a limiting support, a spring, a fixed sleeve and a fixed rod. According to the reliable single-pipe tower with the anti-falling function, the transmission units are utilized to drive the rotary shaft and the second rolling wheels to rotate so as to retract cables, thus the lifting device moves upwards, and due to the fact that the diameter of a driving wheel is longer than that of a driven wheel, labor-saving operation is achieved. In addition, the handles are clamped on the fixed sleeve through the anti-falling units, so that the working platform is prevented from keeping falling to cause falling accidents, and accordingly the safety and the reliability of the single-pipe tower are enhanced.

Description

technical field [0001] The invention relates to the field of communication iron towers, in particular to a reliable single-pipe tower with a fall prevention function. Background technique [0002] At present, single-pipe towers are often used in the field of communication technology, and their main function is to support communication antennas to achieve communication signal coverage. Single-pipe towers have the characteristics of small footprint and beautiful appearance, and have been widely used in the communication industry. At the same time , with the advancement of urban information construction, the demand for single-pipe towers is also rising rapidly. [0003] In order to facilitate the maintenance of the communication antenna on the top of the single-pipe tower, there are usually ladders on the single-pipe tower for the staff to climb. However, these ladders have a simple structure and are prone to fall accidents due to the negligence of the staff during the climbing...
