Problems solved by technology

[0002] With the construction of a large number of ultra-high voltage transmission lines, a large number of iron towers with double angle steel as the main material are used in large quantities. At the same time, a large number of transmission lines are inevitably built in coal mining subsidence areas, resulting in different degrees of subsidence of some transmission towers. and tilt, which pose a serious threat to the safe operation of transmission lines
However, the existing iron tower deflection correction device requires a large amount of tools, complex site layout, heavy workload, and high labor intensity for workers.

Embodiment Construction

[0017] An embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0018] The deviation correcting device for inclined power transmission towers with double angle steel main materials of the present invention is composed of a main hydraulic prop, an angle steel inner holding card 1, and an auxiliary corner card 2. The hydraulic prop is composed of a hydraulic cylinder 4 and a piston rod 8, and the hydraulic prop is hinged. The base 6 is symmetrically arranged on the supports 7 on both sides of the inclined transmission tower, such as figure 1 As shown; on the left and right sides of the transmission tower of the main material of the double angle steel, there are two angle steel inner holding cards 1 symmetrically, and two auxiliary angle cards 2 are symmetrically arranged on the front and rear sides, as Figure 7 Shown; Described angle steel inner holding card 1 is made of V-shaped connecting plate 12, two wing plates and ...

Abstract

The invention discloses a device for correcting an inclined iron transmission tower of double combined angle steel main material, wherein the device is particularly suitable for correcting the inclined iron transmission tower in a coal mine subsidence area. The device comprises an eyelet bolt, an angle steel inner clamp, an auxiliary corner brace, a pressure sensor, a hydraulic supporting column, a base and the like. When differential settlement happens to the iron transmission tower of double combined angle steel main material in the coal mine subsidence area, the device for correcting the inclined iron transmission tower can adjust the iron transmission tower and release the structural additional internal force and deformation which are caused by the differential settlement of a foundation to the iron transmission tower in a mining area, thereby ensuring safety of the iron transmission tower. The device is high in bearing capacity, low in number of tools, flexible in operation, convenient to construct and high in accuracy and reliability and has wide practicability.

Description

technical field [0001] The invention relates to a deflection correcting device for a power transmission tower, in particular to a deflection correcting device for an inclined power transmission tower which is suitable for a double angle steel main material used in a coal mine goaf. Background technique [0002] With the construction of a large number of ultra-high voltage transmission lines, a large number of iron towers with double angle steel as the main material are used in large quantities. At the same time, a large number of transmission lines are inevitably built in coal mining subsidence areas, resulting in different degrees of subsidence of some transmission towers. and tilt, which pose a serious threat to the safe operation of the transmission line. However, the existing iron tower deflection correction device requires a large amount of tools, complex site layout, heavy workload, and high labor intensity for workers. Therefore, there is an urgent need to study a de...
