Rust removing device used for outer wall of square cylinder

Abstract

The invention relates to the technical field of rust removing of outer walls of square cylinders, in particular to a dust removing device used for the outer wall of a square cylinder. A servo motor isadopted for driving a reciprocating screw rod to rotate, a moving nut moves back and forth in the axial direction of the reciprocating screw rod, and an installation plate is driven to synchronouslymove through a first connecting rod; meanwhile, a first rotating shaft moves along with an installation plate, a driven gear and a rack act, the driven gear drives the first rotating shaft to rotate to act on a first rust removing assembly, and therefore the first rust removing assembly can also rotate while moving vertically, and the rust removing effect is optimized; a driving assembly also actson a rotating assembly through a transmission assembly, a sheave structure is adopted for completing face changing, comprehensive rust removing can be conveniently conducted on the outer wall of thesquare cylinder, during face changing, an electric wire collecting wheel is adjusted for conducting wire collecting, a rotary disc gets away from the square cylinder, and the phenomenon that the square cylinder interferes with the first rust removing assembly during rotation is avoided; and meanwhile, when the square cylinder rotates along with the rotating disc, the top of the square cylinder anda second rust removing assembly act, and rust removing is conducted.

Description

technical field [0001] The invention relates to the technical field of derusting the outer wall of a square cylinder, in particular to a derusting device for the outer wall of a square cylinder. Background technique [0002] The role of the cylinder is to provide the pressure space required by the process. It is one of the most important pressure components of the pressure vessel, and its inner diameter and volume often need to be determined by process calculations. Cylindrical barrel (ie cylinder) and spherical barrel are the most commonly used barrel structures in engineering. [0003] When the diameter of the cylinder is small (generally less than 500mm), the cylinder can be made of seamless steel pipe. At this time, there is no longitudinal weld on the cylinder; Press it into two semi-cylinders, and then weld the two together with a weld to form a full cylinder. [0004] In addition to cylinders and spherical cylinders, there is another common cylinder, the square cyli...

AI Technical Summary

Problems solved by technology

[0009] Some manufacturers use iron sheets or other materials for processing in order to save costs when manufacturing square tubes, and lack sufficient anti-rust treatment. As a result, such products can be used normally at the initial stage of production, but after storage or use for a period of time, Due to the influence of the environment or other reasons, the outer wall will rust, which will affect its service life

[0010] However, in the prior art, there are few derusting devices for square cylinders, and the degree of automation is low; if the cylinder derusting equipment is directly used, due to its cross-sectional shape, it is easy to cause interference between the derusting parts and the square cylinder during switching. cause problems

[0011] Therefore, for the derusting work of the square cylinder, there is not yet a relatively complete mechanical equipment that can better solve the problem.
