An external galvanizing device for welded pipes

Abstract

The invention discloses a pipe welding outward galvanization device, and belongs to the technical field of pipe welding outward galvanization. A first fixing base and a second fixing base are arranged on the two sides of a zinc pot correspondingly, an electric motor is arranged on the outer side of the first fixing base, a driving gear is arranged at the power output end of the electric motor, and is engaged with a driven gear, the driven gear is arranged on the outer side of the first fixing base through a connecting shaft, the connecting shaft transversely penetrates the first fixing base and extends to the interior of the zinc pot, a gear disc is arranged at the end of the connecting shaft, five outwards-extending wheel teeth are at least arranged on the peripheral edge of the gear disc evenly, a hanging pipe device is rotatably connected to the outer side of each wheel tooth through a rotating shaft, and a zinc blowing device is fixedly connected to the outer side of the second fixing base. The device has the beneficial effects that manual labor force is reduced, and the welding pipe galvanization work efficiency is greatly improved.

Description

technical field [0001] The invention relates to an external galvanizing device for welded pipes, in particular to a gear plate driven by a motor, the gear plate drives the welded pipe to rotate and completes external galvanizing in a zinc pot, and belongs to the technical field of external galvanizing for welded pipes. Background technique [0002] Hot-dip galvanizing of welded pipe is to put the welded pipe into the zinc pot, and galvanize the wall of the welded pipe to realize the antirust treatment of the welded pipe. The structure of the currently used welded pipe galvanizing device includes a zinc pot, a slide plate with a slope set on one side of the zinc pot whose width matches the length of the zinc pot or the welded pipe, and a sliding material mechanism composed of the slide plate and the welded pipe number control mechanism. , Set in the zinc pot, at least two coaxially rotating toothed plates for accommodating welded pipes, and a pull-out mechanism consisting of ...

AI Technical Summary

Problems solved by technology

Since the welded pipe galvanizing device can only lift a single or two galvanized welded pipes at a time when the galvanized welded pipe lifting mechanism is used to lift the galvanized welded pipe from the galvanized welded pipe to the magnetic roller and enter the next process, when three galvanized welded pipes are lifted When the above galvanized welded pipe enters the groove of the magnetic roller, the welded pipe will be superimposed and inclined, so that the welded pipe cannot smoothly enter the corresponding groove of the magnetic roller and stop

[0003] And at present, stoppers are often used to block the welded pipe when hanging the pipe on the tooth plate. First, the stopper cannot fix the welded pipe well. Second, it takes a lot of time in the process of opening and closing the stopper. Therefore, the equipment has welded pipes. The problem of inefficient galvanizing
