Problems solved by technology

The surface subsidence of the coal mine goaf will cause uneven subsidence of the transmission line tower foundation in the area, which will lead to the inclination, displacement and deformation of the tower, which will cause changes in the internal stress of the tower, which seriously threatens the safety of the line.
In the existing technology, there is no emergency treatment equipment for the inclination caused by the uneven settlement of the transmission tower, and the inclination of the transmission tower cannot be corrected in time

Abstract

The invention relates to a transmission tower differential settlement deviation correction device. An end plate (4) is arranged on the inner side of a barrel (17), the lower end of the barrel (17) is fixedly arranged on a reinforced concrete foundation (15), and a base plate hole (11) is formed in the lower end of the barrel (17); the upper end of a tooth column (5) is fixedly connected with the lower end of a tower foot joint plate (13), the lower portion of the tooth column (5) is inserted into the barrel (17) in a sliding manner, and racks (18) are arranged on the left side and the right side of the tooth column (5); and a pair of large gears (6) are arranged on the two sides of the tooth column (5), two small gears (7) are meshed with the two large gears (6), the large gears (6) and the small gears (7) are all connected to the barrel (17) rotationally, the large gears (6) are meshed with the racks (18), and at least one end of a small gear shaft (9) extends to the outer side of the barrel (17) and is fixedly connected with a handle or a driving wheel (10). The device is used for deviation correction adjustment on inclined tower feet after differential settlement happens.

Description

technical field [0001] The invention belongs to the field of design and protection of power transmission lines in coal mine goafs, and relates to a settlement adjustment device for power transmission towers, in particular to a device for correcting uneven settlement of power transmission towers. Background technique [0002] Due to the impact of underground mining in coal mines, the overlying strata in the goaf will be dislocated, deformed and fractured, thus forming collapse zones and fault zones. The earth's surface will subside under the action of this disturbance. The surface subsidence of the coal mine goaf will cause uneven subsidence of the transmission line tower foundation in the area, which will lead to the inclination, displacement and deformation of the tower, which will cause changes in the internal stress of the tower, which seriously threatens the safety of the line. In the prior art, there is no emergency treatment equipment for the inclination caused by the...
