A tower foundation sinking reset device

Abstract

This utility model discloses a tower foundation sinking and resetting device, including a tower base and a base plate. The tower base is located above the base plate. Multiple support plates are provided on the upper surface of the base plate. Positioning plates are provided at both ends of each support plate. Two sliding seats are symmetrically arranged on the inner sides of the two positioning plates. A top plate is provided above the support plates. Two positioning seats are symmetrically arranged at the bottom of the top plate. A transmission component is movably connected between the positioning seats and the sliding seats. In this application, a top plate is provided. A rotating turntable drives a fourth transmission rod to rotate. The fourth transmission rod transports the top plate to the side of the tower base. Then, a rotating wheel raises the top plate until it is in contact with the tower base, thereby lifting the tower base to its initial position. Because the height of the top plate is variable, even if sinking occurs again, the tower base can be lifted by the top plate. Compared with existing rectification technologies, this method is more efficient, has lower maintenance costs, and is more applicable.

Description

Technical Field

[0001] This utility model relates to the technical field of iron tower foundation reset devices, and in particular to an iron tower foundation sinking reset device. Background Technology

[0002] Transmission line towers (referred to as iron towers) are the core supporting structure of overhead transmission lines, mainly used to erect high-voltage conductors and ground wires. Transmission line towers traverse most areas and are erected in various terrains. During erection, a tower base is generally set at the bottom of the tower to fix the tower in place in the area to be erected. Although the existing tower erection technology is quite mature, some problems still occur during use. For example, the tower may tilt due to foundation settlement. After the tower tilts, it needs to be corrected. The current method is to use jacks to support the tower base, then pour concrete under the tower base, and then use steel pipes to increase the strength of the concrete. This construction method is not only costly but also inefficient. Summary of the Invention
