Manufacturing method of intermateable plug-in type steel pipe pole tower

Abstract

The invention relates to a manufacturing method of an intermateable plug-in type steel pipe pole tower, comprising the following steps: (1) calculation of plate width: according to the mouth breadth and thickness of steel pipes based on design specifications, single-side length of non-welded sides and welded sides and plate width when single-combining and double-combining are calculated; (2) discharging of steel plates: in the gun-releasing process of a discharging cutting nozzle, an operating table surface guarantees the planeness of a purchasing plate and a technique tip angle for tool-setting is formed when the steel plates are discharged; (3) the bending of the steel plates: operators are needed to adjust the central position of a pressing cutter to fall down to the center of a bendingedge; and (4) seam jointing: the process of combining and assembly before two bent steel plates being moulded into steel pipes comprises the steps: (4.1) control of diameter of a pipe port and roundness of the pipe port; (4.2) control of torsion of the bending edge; and in seam jointing, a jack and a draw hook tool are used for carrying out alignment correction on misaligned edges. The inventioncan realize batch intermateable, and reduces construction strength and construction convenience.

Description

A method of manufacturing an interfitting plug-in steel pipe tower technical field The invention relates to a manufacturing method of a plug-in steel pipe tower. Background technique With the rapid development of the power industry, the scale of investment in power infrastructure has been increasing in recent years. The plug-in (socket) steel pipe pole has the characteristics of simple structure, beautiful appearance, small foundation area, and convenient construction. It has been more and more used in the construction of power lines, especially in urban power line towers. pole tower. At present, domestic power line steel pipe towers mainly adopt two connection methods, namely flange connection type and plug-in (sleeve) connection type. The flange connection type has relatively complicated processing procedures due to the existence of flange connection nodes, and its appearance is not as good as plug-in (sleeve) connection. ) connected steel pipe poles are beautiful, so ...
