AI Technical Summary

Technical Problem

In existing technologies, wind turbine tower tube sections require large top molds to position the corrugated pipes during the manufacturing process, resulting in high production, transportation, and installation costs, and making it difficult to adapt to the needs of different tube segment sizes, thus leading to low efficiency.

Method used

A corrugated pipe clamp is used to fix the position of the corrugated pipe at the top, and a positioning seat is used to fix the position of the corrugated pipe at the bottom. A positioning rod is inserted in the middle and positioned by elastic fasteners to ensure the positional accuracy and stability of the corrugated pipe and reduce the construction difficulty.

Benefits of technology

It achieves precise positioning of corrugated pipes, reduces construction difficulty and cost, improves production efficiency, and adapts to the needs of different pipe segment sizes.

Abstract

The application discloses a corrugated pipe fixing device, a tower drum mold and a tower drum pipe section. The corrugated pipe fixing device comprises a corrugated pipe clamp, a plurality of positioning seats, a plurality of positioning rods and a plurality of elastic fasteners. The plurality of positioning seats are arranged at the bottom of a pouring cavity. The top ends of the plurality of positioning rods pass through the through holes on the corrugated pipe clamp one by one and extend upwards. The bottom ends of the plurality of positioning rods are connected to the plurality of positioning seats one by one. The positioning rods are used for being inserted into the corrugated pipe to position the corrugated pipe. The elastic fasteners press the positioning rods downwards. The corrugated pipe fixing device realizes the position fixing of the corrugated pipe and guarantees the position precision of the corrugated pipe. The elastic fasteners are used for elastically pressing the positioning rods, so that the upward movement or upward floating of the positioning rods during pouring is prevented, and meanwhile, the positioning rods are subjected to certain error compensation, so that the installation position of the positioning rods is stable.
