A paint brushing device for buried pipelines

Abstract

The invention discloses a buried pipeline paint brushing device. The device comprises a machine body, an advancing device is mounted in the machine body, and comprises a rotating advancing caterpillarband, when the advancing caterpillar band rotates, the machine body is driven to move, a hydraulic cylinder is mounted in the machine body, a telescopic shaft is mounted at an upper end of the hydraulic cylinder, an upper end of the telescopic shaft is fixedly provided with a driving main body, and a driving device is mounted in the driving main body. The buried pipeline paint brushing device isprovided with six brush coating blocks which are annularly mounted in an array manner and can be telescopically adjusted, a rubber air cylinder which has elasticity and can be stretched is mounted between the brush coating blocks in a sleeved manner, paint brushes are mounted on the outer surface of the rubber air cylinder, through brush painting telescopic devices, the paint brushes are adjustedto be attached to an inner end wall of a pipeline, through the advancing device, the paint brushes are driven to move along the pipeline, the driving device drives the paint brushes to rotate, the paint brushes carry out continuous and uniform paint brushing work on an inner wall of the pipeline, manual brush coating is not needed, the buried pipeline paint brushing device is suitable for pipelines with different diameters, the use range of the buried pipeline paint brushing device is wide, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of painting equipment, in particular to a painting device for buried pipelines. Background technique [0002] The purpose of painting the surface of objects is to improve the surface anticorrosion, antirust, beautification, sealing and other factors of the object. The general painting equipment is large in size and can be used for painting objects indoors or outdoors in large spaces, but for buried The painting work of underground pipelines is usually painted manually, but due to the difference in the inner diameter of some pipelines, some pipelines have narrow inner diameters, which make it difficult for personnel to move around, and there is little oxygen in the buried pipelines, so there are certain potential safety hazards. Therefore, the current technology first Paint the interior of the small sections of the pipeline, and then splice the small sections to realize the painting of the interior of the pip...

[0002] The purpose of painting the surface of objects is to improve the surface anticorrosion, antirust, beautification, sealing and other factors of the object. The general painting equipment is large in size and can be used for painting objects indoors or outdoors in large spaces, but for buried The painting work of underground pipelines is usually painted manually, but due to the difference in the inner diameter of some pipelines, some pipelines have narrow inner diameters, which make it difficult for personnel to move around, and there is little oxygen in the buried pipelines, so there are certain potential safety hazards. Therefore, the current technology first Paint the interior of small sections of pipes, and then splice the small sections to realize the painting of the interior of the pipes, but this process takes a long time, the work efficiency is low, and the paint and sealing of the joints of the pipes are poor
