[0019] In order to make the above-mentioned purpose, features and advantages of the utility model more obvious and easy to understand, the specific embodiment of the utility model is explained in detail below. In the following description, a lot of specific details are set forth in order to fully understand the utility model. However, the utility model can be implemented in many other ways different from the description herein, and those skilled in the art can make similar improvements without departing from the connotation of the utility model, therefore, the utility model is not limited by the following disclosed specific implementation.

[0020] Please refer to Figs. 1 to 3 , the embodiment of the utility model discloses a kind of angle steel tower crossing fence device, including tower unit and fence unit.

[0021] The tower unit includes two corner steel towers 1 set opposite each other, with the area between the two corner steel towers 1 being a crossing area, such as complex terrain and obstacles like highways, railways, high-speed railways, power lines, gas pipelines, etc.

[0022] The safety net unit includes temporary crossarms 2 installed on the angle steel tower 1, multiple supporting ropes 3 spaced between two temporary crossarms 2, and an insulating safety net 4 fixed at equal intervals to the supporting ropes 3. The connection between the insulating safety net 4 and the supporting ropes 3 is sealed with bolts. The temporary crossarms 2 serve as the support platform for the crossing safety net. The crossing protection range of the insulating safety net 4 is determined according to the length and width of the road or line being crossed. The four corners of the insulating safety net 4 and the outer sides of the two temporary crossarms 2 are connected to ground anchors 6 by guy wires 5. The ground anchors 6 are located on both sides and outside the four corners of the angle steel tower 1.
