Environment-friendly painting device

Abstract

An environment-friendly painting device comprises a mounting rack and painting assemblies symmetrically mounted on the left side and the right side of the mounting rack. Sliding cavities are symmetrically formed in the two sides of the mounting rack. Each painting assembly comprises a sliding frame mounted in the corresponding sliding cavity in a sliding manner and a rotating barrel rotationally mounted at the upper end of the sliding frame through a rotating pin shaft. A mounting groove is further formed in each sliding frame. A first electromotor is fixedly mounted in the side wall of each mounting groove. A tooth-shaped wheel is fixedly mounted on a conveying shaft of each first electromotor. A tooth-shaped strip connected with the corresponding tooth-shaped wheel in a matched manner is fixedly mounted on the outer ring of each rotating barrel. A sliding groove with an opening facing a pipe is formed in each rotating barrel. A control rod extending towards the pipe is mounted in each sliding groove in a sliding manner. A screw hole with an opening away from the pipe is formed in each control rod. A first screw shaft is mounted in each screw hole in a thread fit manner. Each first screw shaft is connected with a second electromotor fixedly mounted in the corresponding rotating barrel. Elastic painting arms used for penetrating into the pipe and used for painting are arranged on the end face, facing the pipe, of each rotating barrel in an up-and-down symmetry manner.

Description

technical field [0001] The invention relates to the technical field of environmental protection painting, in particular to an environmental protection painting device. Background technique [0002] In the actual processing and production of pipelines, the inner walls of pipelines are often painted with corresponding environmentally friendly coatings (such as anti-corrosion coatings, heat-insulating coatings, etc.) according to actual requirements to increase heat insulation and anti-corrosion performance and improve service life. At present, mechanical devices are generally used to paint the inner wall of the pipeline. However, the structure of these inner wall painting devices is complex, and for pipes with different inner diameters, it is often necessary to replace different paint heads, which is very inconvenient to operate. For some lines on the inner wall of the pipeline It is not easy to paint, and the painting effect is not ideal. Contents of the invention [0003]...
