Detailed Description

In order to more fully explain the practice of the utility model, examples of the practice of the utility model are provided. These examples are merely illustrative of the present utility model and do not limit the scope of the utility model.

The utility model will be explained in further detail with reference to the accompanying drawings, in which: 1: a tower body; 2: a stay wire A;3: a basket bolt A;4: a fixed pulley A;5: a basket bolt B;6: a stay wire B;7: a fixed pulley B;8: a fixed shaft; 9: a rotating wheel; 10: an adjusting sleeve; 11: an index plate; 12: a jack; 13: positioning holes; 14: a U-shaped wheel carrier A;15: an embedded part A;16: a U-shaped wheel carrier B;17: and the embedded part B.

As shown in fig. 1, a guy iron tower comprises a tower body 1 and guys, wherein the tower body is fixed on the ground, the upper ends of the guys are fixedly connected to the tower body, four guys are uniformly distributed around the tower body at intervals of 90 degrees, two guys are shown in fig. 1, in fig. 1, the stay wires between the two basket bolts and the tower body are two independent sections, the stay wire between the two basket bolts can be a complete section, and the fixed connection of the two stay wires after passing through the fixed pulley in the utility model comprises an integrated form.

Four embedded parts uniformly distributed along the tower body are fixedly installed on the ground, the positions of the four embedded parts correspond to the positions of the lower ends of the four stay wires one by one, a fixed pulley is installed on each embedded part, two stay wires which are 180 degrees apart pass through the fixed pulley and are fixedly connected together, two basket bolts are connected to the two stay wires which are 180 degrees apart, the two basket bolts are respectively A3 and a B5, and in the embodiment, the two basket bolts are adopted, and because the lower parts of the two stay wires are adjacent, the tightness degree can be adjusted by adopting one basket bolt. In fig. 1, two embedded parts are an embedded part A15 and an embedded part B17, a U-shaped wheel carrier A is hinged on the embedded part A, a U-shaped wheel carrier B is hinged on the embedded part B, a fixed pulley A is rotationally connected on the U-shaped wheel carrier A, the fixed pulley B is rotationally connected on the U-shaped wheel carrier B, a fixed shaft 8 in the vertical direction is fixedly connected between two fixed pulleys opposite to each other on the ground, threads are machined on the upper portion of the fixed shaft, an adjusting sleeve 10 is screwed on the threads, a rotating wheel 9 is sleeved on a rotating shaft in a vertical sliding mode, and the rotating wheel 9 is in butt joint with the adjusting sleeve 10.
