Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] After the mechanism is installed, such as figure 1 shown. At this time, the jacking plate 4 needs to be raised to the working position, the electric control device sends out a signal, the oil delivery hole 20 starts to enter the oil, the piston rod 19 moves upwards, and the head of the piston rod 19 makes the U-shaped latch plate 15 and the jacking plate 15 and the jacking plate through the pin 17. Lifting plate 4 moves upwards, and when reaching the predetermined working position (judged by the position sensor), if figure 2 As shown, the electric control device controls the hydraulic lock 21 to lock the oil circuit to reach the working state.

[0025] When the monitoring device detects that the transmission line tower is tilted, the monitoring device calculates the displacement required for the jacking mechanism of each leg based on ...

Abstract

The invention provides an anti-overturning jacking mechanism for a power transmission line tower. The anti-overturning jacking mechanism mainly comprises hydraulic cylinders, piston rods, U-shaped bolt plates, a jacking plate, a heat preservation layer, a limiting plate and a temperature sensor, wherein the hydraulic cylinders are installed on a bottom plate and a cement foundation through foundation bolts, the piston rods in the hydraulic cylinders are connected with the U-shaped bolt plates through cotter pins, the U-shaped bolt plates are connected with the jacking plate through bolts, and supporting legs of the power transmission line tower are installed on the jacking plate. When the power transmission line tower is inclined, the displacement of the supporting legs of the power transmission line tower is adjusted by adjusting the movement of the piston rods of the hydraulic cylinders. The mechanism acts on the bottoms of the four supporting legs of the power transmission line tower and solves the problem that the power transmission line tower cannot dynamically compensate or adjust itself when the foundation of the power transmission line tower is subjected to differential settlement at present.

Description

technical field [0001] The patent of the invention belongs to the technical field of anti-tipping technology of a transmission line tower in a high-voltage power transmission system, and specifically relates to an anti-tipping jacking mechanism of a transmission line tower. Background technique [0002] As an important carrier of overhead transmission lines, the transmission line tower has been working in the field for a long time and has withstood the test of various harsh natural environments. There are many factors that affect the stability and safety of the transmission line tower structure. As we all know, the erection of transmission lines will inevitably pass through areas prone to geological changes such as collapsible loess areas and mineral (such as coal) gobs. The unstable geological conditions in these areas will cause the foundation of the transmission tower to subside, thereby It will cause the transmission line tower to be tilted, deformed or even overturned, ...
