Description

Technical Field

[0001] The present invention relates to the technical field of mobile communications, and more particularly to a three-tube tower skirt type curtain anti-falling safety net. Background Art

[0002] Safety is a crucial issue during high-altitude operations on communication towers, impacting both the smooth progress of operations and the safety of workers. Workers face the risk of falling objects and injuries to those on the ground. Currently, during tower installation, inspection, and maintenance, fall protection is limited to measures such as wearing non-slip shoes, hard hats, and safety belts. This requires high-quality workers and lacks effective external protection. Furthermore, falling objects pose a significant risk to workers working at height, as well as those working or passing through the towers. These objects range from small hand tools to large items such as equipment and materials. When objects fall from height, they can cause serious injury or death upon impact. Furthermore, during tasks such as demolition, construction, or outdoor operations in strong winds, objects can become dislodged and fall, posing a significant safety hazard. Summary of the Invention

[0003] The present invention provides a three-tube tower skirt-type curtain anti-fall safety net. Currently, there are no effective external protection measures for workers and objects falling from high altitudes during the installation, inspection and maintenance of iron towers, or for avoiding and reducing injuries caused by falling objects. It is now proposed to set up anti-fall safety nets inside and outside the three-tube tower. The anti-fall safety nets can effectively reduce the impact force of falling, provide a certain buffer and support force, and reduce the risk of injuries and casualties caused by workers and objects falling. The design concept of the three-tube tower skirt-type curtain anti-fall safety net is to provide all-round safety protection for workers on communication base station towers. This safety net not only covers the outside of the tower, but also extends to the inside, forming a "skirt curtain-type" double protection, which greatly reduces the risk of injury when a falling accident occurs.

[0004] The present invention is divided into an internal anti-fall safety net and an external anti-fall safety net. The internal anti-fall safety net is made of polypropylene, with a size of 2000x2000mm, a mesh size of 40mm, and a mesh size of 150x150mm. Each side of the safety net is fixed to the crossbar with two shackles, and at the same time, the steel wire rope is wrapped around the main material of the tower body and fixed with a shackle to form an internal triangular anti-fall safety net. The external anti-fall safety net is made of polypropylene, with a size of 14000x28000mm, a mesh size of Φ6mm, and a mesh size of 120x120mm. The safety nets are fixed with bayonet connections. The top of the safety net is pulled to the installation elevation through a crossbeam, and each side of the safety net is fixed to the crossbar with a shackle, with a shackle spacing of 800mm. The top of the safety net is connected to the steel wire rope with a spring buckle, and at the same time, the steel wire rope is wrapped around the main material and fixed with a wire clamp. The bottom rope of the safety net is secured to the ground stakes via spring clips. The stakes are L50x5 steel angles, sharpened at one end and driven into the soil. The angles are 1600mm long, with Φ89x5x60mm sleeves welded to the top and 400mm from the top. The stakes are spaced no more than 1400mm apart. Bamboo used should be at least three years old, approximately 800-1000mm long and Φ60-70mm in diameter. Finally, the safety net is flattened and hung from the stakes to form an external fall prevention net. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] like Figures 1-10 As shown, this embodiment provides a three-tube tower skirt curtain anti-fall safety net. The outer safety net 1 adopts a safety flat net, which is installed on the four sides of the three-tube tower and installed at a tower elevation of 5 meters. First, a Φ9.5 mm steel wire rope 4 is installed at a tower elevation of 5 meters. The top of the safety net 1 is connected to the steel wire rope 4 with a spring buckle. At the same time, the steel wire rope 4 is wrapped around the main material and fixed with a wire clamp 5. Spread out the safety flat net and gradually use buckles to fix one end of the safety flat net to the steel wire rope 4. The safety flat nets are connected with buckles. Ground piles 6 are driven in sequence at a distance of 5 meters from the tower body (leaving 10 cm), and the angle steel 7 is fixed on the ground pile 6. The safety flat net is straightened and hung on the ground pile 6 and the angle steel 7. The external anti-fall safety net 1 is made of polypropylene, with a size of 14000x28000 mm, a mesh size of Φ6 mm, and a mesh size of 120x120 mm. The safety nets 1 are fixed with bayonet connections. The top of the safety net 1 is pulled to the installation elevation via a crossbeam. Each side of the safety net 1 is secured with shackles and sidewalls, spaced 800 mm apart. The top of the safety net 1 is connected to the steel wire rope 4 with spring clips. The steel wire rope 4 is wrapped around the main material once and then secured with wire clamps 5. The bottom pull rope 2 of the safety net is secured to the ground stakes with spring clips. The ground stakes 7 are made of L50x5 steel angles, sharpened at one end and driven into the soil. The angles are 1600 mm long and have Φ89x5x60 mm sleeves welded to the top and 400 mm from the top. The ground stakes are spaced no more than 1400 mm apart. The bamboo 6 is selected from bamboo that is at least three years old, approximately 1400-1600 mm long and Φ60-80 mm in diameter. Finally, the safety net 1 is flattened and hung on the ground stakes to form the external fall prevention safety net 1.

[0017] The inner safety net 8 is made of polypropylene and measures 2000x2000mm, with a mesh size of 40mm and a mesh size of 150x150mm. Each side of the safety net 8 is fixed with two shackles and crossbars. At the same time, the wire rope 4 is wrapped around the main material of the tower body and fixed with shackles to form an internal triangular anti-fall safety net 8.

[0018] The beneficial effects of the present invention are:

[0019] The present invention uses a polypropylene flat hanging net inside the three-tube tower and a polypropylene safety flat net on the outside. In the event of a fall, the anti-fall net can provide a strong buffer, reducing the impact force of falling objects on the human body, thereby alleviating injuries and reducing the risk of casualties. The design of the skirt curtain structure allows the safety net to fit more closely to the tower body, reducing wind resistance and swinging, while increasing the stability and load-bearing capacity of the net. In addition, the effectiveness and reliability of the safety net when subjected to impact are ensured through precise weaving technology and reasonable mesh density design. In view of the problem that 70% of safety hazards in communication operations come from live operations, the design of this anti-fall net specifically considers electrical safety factors, and effectively prevents operators from falling accidents caused by electric shock or other reasons through physical barriers.
