Abstract

The invention discloses a deviation rectification device for a steel pylon, and particularly relates to a jacking device for deviation rectification of the steel pylon in a mining area of a coal mine. The jacking device for deviation rectification of the steel pylon in the mining area of the coal mine comprises an independent long-column concrete foundation (1), foundation bolts (3) and a pylon leg plate (4) capable of being jacked, wherein the pylon leg plate capable of being jacked (4) comprises a base plate (6) and a steel pylon principle material connecting plate (8) welded to the base plate (6), the steel pylon principle material connecting plate (8) is welded to a steel pylon principle material (5) along the edge, the base plate (6) of the pylon leg plate capable of being jacked (4) is connected with the independent long-column concrete foundation (1) through the foundation bolts (3), loading holes (7) used for installation of jacks (2) are formed in the independent long-column concrete foundation (1), and the length of exposed screw threads of each foundation bolt (3) is no smaller than 150mm. According to the structural system, the jacking device for deviation rectification of the steel pylon in the mining area of the coal mine is simple in structure, when the steel pylon inclines, the foundation bolts (3) are loosened, the jacks can be used for directly jacking the pylon leg plate capable of being jacked, and deviation rectification can be carried out.

Description

technical field [0001] The invention relates to a deflection correcting device for a power transmission tower, in particular to a deflection correcting and jacking device for a power transmission tower in a coal mine mining area. Background technique [0002] Due to the changes in the geological structure of the coal mine mining area, the transmission towers built in the mining area are prone to sinking and tilting to varying degrees, which poses a serious threat to the safe operation of the transmission line. The current way to solve this problem is to correct the deflection by modifying the tower structure or foundation after the transmission tower is tilted. This method requires a large amount of tools, complex site layout, and relatively large workload and labor intensity. Contents of the invention [0003] Aiming at the problems existing in the above-mentioned prior art, the present invention provides a deflection correcting and jacking device for power transmission ...
