Servo linkage jacking deviation rectification control system and method for inclined iron tower in mining area

Abstract

The invention discloses a servo linkage jacking deviation rectification control system and method for an inclined iron tower in a mining area. According to the system, iron tower foundation #-shaped inverted beams are fixedly mounted on four independent foundations of a power transmission iron tower; an along-line direction inclinometer and a vertical-line direction inclinometer are respectively arranged on one side of the along-line direction and the vertical-line direction of the power transmission tower; four hydraulic jacks are supported on two adjacent sides with relatively large vertical sinkage in pairs; the four vertical supports are supported on two adjacent sides with relatively small vertical sinkage in pairs; a hydraulic pump station is connected with the hydraulic jacks through a high-pressure oil pipe; and a power supply system is connected with the hydraulic pump station and the power utilization end of the PLC control system through power lines. The method comprises the steps: measuring the inclination direction and inclination value of the power transmission tower; determining an arrangement scheme of the hydraulic jacks; starting the PLC control system, and carrying out deviation rectification operation of the power transmission tower; and observing and evaluating the deviation rectification effect. According to the system and method, the automatic deviation rectification process can be achieved favourably, the deviation rectification efficiency is high, and the deviation rectification effect is good.

Description

technical field [0001] The invention belongs to the technical field of deflection correction for power transmission iron towers, and in particular relates to a deflection correction control system and method for servo linkage jacking of inclined iron towers in a mining area. Background technique [0002] With the continuous development of the economy, the demand for electricity is also increasing year by year, and the construction and development of the national grid is accelerating. The construction of the national grid is of great significance to ensure national energy security and reliable power supply. The transmission tower is an important part of the construction of the national grid. As the main support for long-distance power transmission, its stability is very important. Most of the transmission towers are towering structures, which are sensitive to inclination deformation and have high requirements for uneven settlement of the foundation. In some areas where water...
