Device arranged on original foundation of high voltage transmission tower and capable of hoisting height of tower and preventing mining-induced deformation

Abstract

The invention discloses a device which is arranged on the original foundation of a high voltage transmission tower and capable of hoisting the height of the tower and preventing mining-induced deformation. The device comprises a metal foundation sheath sleeved on the original foundation of a high voltage transmission tower, a reversible translation support arranged on the foundation sheath, and a vertical lifting support arranged on the reversible translation support, wherein the upper end of the vertical lifting support is connected with the tower leg of the high voltage transmission tower, and the vertical lifting support is composed of a hydraulic lifting support and a fine-tuning lifting device. The device of the invention is arranged on the original foundation of a high voltage transmission tower, and has the functions of hoisting the height of the tower and preventing mining-induced deformation, thereby solving the problem that the earth surface subsidence caused by coal mining has an effect on the high voltage transmission tower, and ensuring the safety of the tower, and realizing the stoping of resources under the high voltage transmission tower.

Description

technical field [0001] The invention relates to a device for lifting and resisting surface deformation of a high-voltage line tower installed on the original foundation, which is suitable for the case of small ground subsidence, so that the high-voltage line tower can overcome the influence of surface subsidence and deformation on the safety of the high-voltage line tower and power supply system, Thereby realizing the reasonable mining of deposits under the high-voltage line tower. Background technique [0002] my country is a big mining country, and coal mines are widely distributed. In coal mine gobs, surface subsidence is often unavoidable. At the same time, whether it is a new high-voltage line or an existing high-voltage line passing through the coal mining area, there is a common problem of high-voltage line towers pressing coal. [0003] Existing high-voltage line towers generally include a tower head, a tower body, and tower legs, and the tower legs mainly play a s...
