Debugging method for tower foot board of power transmission tower

Abstract

The invention provides a debugging method for a tower foot board of a power transmission tower. The method comprises the steps of calculating a farthest distance between a screw hole and angle steel, and a farthest distance between the screw hole and a boot board; calculating a bending moment of a pulled bottom board for the wall of the angle steel, a bending moment of the pulled bottom board for the boot board, and a bending moment per unit length; determining a check distance between the screw hole and the boot board, a check distance between the screw hole and a ribbed board, a deviation value of the boot board, check thickness of the bottom plate, check height of the boot board and a check value of basic foot distance increment; and comparing the check distances, the deviation value, the check thickness, the check height and the check value with measured actual parameter values of the tower foot board, and debugging the tower foot board according to a comparison result. According to the debugging method for the tower foot board of the power transmission tower, proposed by the invention, actual stress conditions of members are effectively simulated; the calculation process and the check process are both simple and clear, so that designers can conveniently perform check calculation of the tower foot board of the power transmission tower; and the tower foot board is debugged according to the result, so that the optimal configuration of the tower foot board is ensured, the normal work of the tower transmission tower is ensured, the debugging efficiency of the tower foot board of the power transmission tower is improved, and the working reliability and safety of the power transmission tower are enhanced.

Description

technical field [0001] The invention relates to a debugging technology of a power transmission tower, in particular to a debugging method of a foot plate of a power transmission tower. Background technique [0002] The transmission tower is the supporting point of the overhead line. One circuit is erected on the transmission tower, which is a single-circuit transmission tower, and two circuits are erected on the transmission tower, which is a double-circuit transmission tower. A single circuit refers to a circuit in which a load has one power supply; a double circuit refers to a circuit in which a load has two power supplies. Generally, enterprises that require high power supply reliability, or important substations in the region, use double-circuit power supply, which can protect one power supply from power failure for some reason, and the other power supply can continue to supply power. However, for general small and medium users who do not require high power supply relia...

Problems solved by technology

[0003] At present, there is no reasonable and reliable way to adjust the design and adjustment of the foot plate; if the design of the foot plate is unreasonable, it cannot be debugged effectively and reliably; it is easy to be damaged or even cause accidents after long-term use, which brings safety to people.
