Embodiment 1

[0021] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, a combined cleaning device for the inner and outer walls of steel pipes includes an outer pipe brush 3 device for cleaning the outer wall of the steel pipe and an inner pipe brush 4 device for cleaning the outer wall of the steel pipe. The outer tube brush 3 is a cylinder, and the inner wall of the cylinder is provided with bristles, which can clean the outer wall of the steel pipe 15 when the bristles rotate relative to the steel pipe. Sixteen magnets 18 are arranged on the wall of the cylinder along the circumference of the cylinder, and the electromagnets arranged in the circumference are defined as one group, and six groups of such electromagnets are arranged along the axial direction of the cylinder. The cylindrical body of the outer tube brush is supported on the bearing 5, so that the casing 3 can rotate flexibly. The cylinder body of the outer tube brush is covered with a belt 801 and a pulley con...

Embodiment 2

[0024] The difference from the first embodiment is that the magnet 18 provided on the wall of the outer tube brush cylinder is an electromagnet with controllable current. The cylinder body of the outer tube brush is fixed on the support without a belt transmission mechanism. The upper and lower guide wheels on the support are replaced by bearings that can support steel pipes to rotate freely. The cylinder of the inner tube brush 4 is provided with 4 slide grooves along the radial direction of the cylinder section circle, that is, with the axis of the cylinder of the inner tube brush as the center, on the cylinder of the inner tube brush Several chutes 16 perpendicular to the axis of the cylinder are provided. A slide bar 17 is arranged inside the chute 16 , and a spring 20 is connected between the bottom end of the slide bar 17 and the bottom end of the chute 16 . The top of the slide bar 17 is provided with a flexible friction head 19, such as a rubber head.

Abstract

The invention provides an inner and outer wall combined cleaning device for steel pipes, and belongs to the technical field of steel pipes, and solves the problem of inconvenience for inner and outer wall cleaning of the steel pipes in the prior art. The inner and outer wall combined cleaning device for the steel pipes comprises an outer pipe brush and an inner pipe brush, wherein the outer pipe brush is a cylinder; brush bristles are arranged on the inner wall of the cylinder; multiple electromagnets are peripherally arranged on the wall of the cylinder; the cylinder is fixed on a bracket; steel pipe brackets are respectively arranged at the sides of two ports of the cylinder; each bracket is provided with a bearing for supporting the steel pipes; the inner pipe brush is a cylinder; brush bristles are arranged on the surface of the cylinder; a magnet is fixed on the cylinder; slide ways are arranged in the radial direction of the section circle of the cylinder on the cylinder of the inner pipe brush; a slide rod is arranged in the slide way; and the bottom end of the slide rod is connected with a spring. The inner and outer wall combined cleaning device for the steel pipes is simple in structure and low in cost, and can greatly improve the cleaning efficiency of the steel pipes.

Description

technical field [0001] The invention belongs to the technical field of steel pipes, and relates to a steel pipe cleaning device, in particular to a device for simultaneously cleaning the inner and outer walls of a steel pipe. Background technique [0002] Before coating the inner and outer walls of the steel pipe, the inner and outer walls of the steel pipe need to be cleaned, so as to clear the dirt on the inner and outer walls of the steel pipe. However, due to the slender and curved surface of the steel pipe, it is not conducive to cleaning, especially for the inner pipe wall. Usually all are to utilize manually to clean up the inner and outer pipe walls of the steel pipe respectively. Not only need a large amount of labor force, and can easily cause outer pipe wall pollution when cleaning steel pipe inner pipe wall, and easily cause pollution to inner pipe wall again when cleaning steel pipe outer pipe wall. Contents of the invention [0003] The purpose of the prese...
