[0002] With the rapid development of the communication industry in China, the large-scale communication steel tower masts have been in service for about 20 to 30 years. During the service period, some of the towers have insufficient bearing capacity, damage, deformation and corrosion of the tower column components, especially the bottom tower column components, due to overloading, collision, fire, foundation deformation, coating damage and the like, and need to be replaced or reinforced. However, these damaged tower columns are mostly located at the bottom of the tower mast structure, and the components cannot be directly replaced, or the stressed tower columns cannot be directly reinforced with load. CONTENT OF THE UTILITY MODEL

[0003] The application provides a device for replacing or reinforcing a three-pipe tower column component of a steel tower mast structure.

[0011] By adopting the above scheme, the operator can drive the worm gear to rotate by rotating the worm, thereby driving the central shaft to rotate. Since the steel cable passes through the central shaft, the rotation of the central shaft will wind the steel cable on the surface of the central shaft, thereby tightening the steel cable. The worm gear and the worm have self-locking property, which can keep the steel cable in a tightened state. The operator can rotate the worm to drive the worm gear to rotate, which is more labor-saving.

[0013] By adopting the above scheme, when the steel cable is tensioned, the operator can rotate the first threaded rod to make the first clamping block and the second clamping block approach each other until the first clamping block and the second clamping block clamp the worm, thereby further preventing the worm from rotating and ensuring that the steel cable will not be loosened.

[0014] Optionally, the anchoring structure comprises a main anchor rod and a base plate, the main anchor rod is slidingly connected with the base plate, the steel cable is hingedly connected with the base plate, and the main anchor rod is inserted into the ground.

[0015] Optionally, the base plate is connected with an auxiliary anchor rod, the auxiliary anchor rod is slidingly connected with the base plate, and the auxiliary anchor rod is inserted into the ground.

[0016] By adopting the above scheme, the base plate is fixed to the ground more tightly.

[0018] By adopting the above scheme, after the main anchor rod is inserted into the ground, the operator can make the propelling block slide in the transmission cavity by rotating the second threaded rod, the propelling block drives the plug rod to be inserted into the ground through the connecting rod, and the fixation of the main anchor rod is further strengthened.
