Steel pole for iron tower of high-tension transmission line

Abstract

The invention discloses a steel pole for an iron tower of a high-tension transmission line. The steel pole comprises a pole body, flanges and mounting frames, wherein the flanges are arranged at the two ends of the pole body, and mounting frames are arranged on the outer wall of the pole body for mounting a steel pole truss, a standing platform and a pedal plate are fixed on the wall of the pole body through the mounting frames; the standing platform comprises a sector pedal plate and two support frames, wherein the inner side of the sector pedal plate is matched with the outer wall of the steel pole, and two support frames are positioned under the sector pedal plate; the inner side of the sector pedal plate and the support frames push against the wall of the steel pole; the side of the sector pedal plate, which is matched with the outer wall of the steel pole, is provided with hanging rings which are fixedly connected with the mounting frames through bolts; the section of the pedal plate is in the bump shape; and the pedal plate is hung in the mounting frames through a bump-shaped hook of the pedal plate. The steel pole is used for erecting the steel pole for the high-tension iron tower of the super high-tension transmission line in the field of electric construction, the problem of difficult assembling in the construction and assembling processes of the steel pole of the high-tension iron tower is solved, a large operation space is provided for workers; during assembling the steel pole, a construction person can freely move between the standing platform and the pedal plate, and is safe and stable, and the construction progress is accelerated.

Description

technical field [0001] The invention relates to a steel pole used for a high-voltage iron tower erecting an ultra-high-voltage transmission line in the electric power construction field. Background technique [0002] In the transmission line, the ultra-high voltage transmission line needs to be erected with a high-voltage iron tower. The high-voltage iron tower is generally a square-shaped iron tower composed of four groups of steel rods assembled vertically. Each group of vertical steel rods connected in series The rooms are also connected with channel steel or angle steel to form a truss structure. The two ends of the steel rod are provided with flanges connecting the two steel rods. The side wall of the steel rod is welded with a mounting frame at the position where the truss angle steel is connected. The mounting frame is a channel-shaped steel plate buckled on the wall of the steel rod. Bolt holes are set on the front of the channel steel plate for connecting angle ste...

AI Technical Summary

Problems solved by technology

However, except for the flange plate connecting the steel rod and the mounting frame connecting the truss angle steel on the general steel pole, there are no other parts for the construction personnel to stand on.

When construction workers assemble steel poles and their truss components, they can only hang them on the steel poles through safety ropes. At the same time, each steel pole is very thick, and climbing tools such as foot buckles cannot be used. Construction workers have no focus on their feet. In this way, the activities of construction personnel are greatly restricted, and the construction process is very difficult and dangerous. It is also very inconvenient during loading and unloading, and it is easy to cause construction accidents.
