Description

Technical Field

[0001] This utility model relates to the field of wind power steel-concrete tower support technology, and in particular to a wind power steel-concrete tower support device. Background Technology

[0002] Wind power generation refers to converting the kinetic energy of wind into electrical energy. Wind is a pollution-free energy source, making wind power generation very environmentally friendly, and it can generate a huge amount of electricity. Therefore, more and more countries are paying more attention to wind power generation. Wind turbines are one of the necessary conditions for the construction of a wind power plant, which mainly consists of three parts: tower, blades, and generator. In addition, it also has functions such as automatic wind steering, blade helix control, and monitoring and protection. The wind speed for operation must be greater than 2 to 4 meters per second (depending on the generator), but too strong a wind speed (about 25 meters per second) is not acceptable. When the wind speed reaches 10 to 16 meters per second, it can generate electricity at full load.

[0003] In the existing wind power steel-concrete towers, the tower is placed on the pre-embedded bolts and then fixed by workers. To prevent the tower from tipping over, external hoisting equipment is used to limit its movement during installation. However, during fixing, the tower, due to its height, will sway due to wind force, thus requiring support and limiting. Summary of the Invention

A limit assembly is connected inside the support assembly, and a fixing assembly is installed at the top of the support assembly. The fixing assembly includes clamps located on both sides of the tower. Support shafts are provided on opposite sides of the clamps and the support assembly. A connecting rod is rotatably connected to the outside of the two sets of support shafts, and a connecting threaded rod is installed between the two sets of clamps. A fixing nut is provided on the outside of the connecting threaded rod.

[0007] Preferably, the mounting base is inserted into the pre-embedded bolt, and the mounting base has a through hole corresponding to the pre-embedded bolt.
