Adjustable conveying pipeline connecting piece oiling machine

Abstract

The invention belongs to the technical field of pipeline oiling, and particularly relates to an adjustable conveying pipeline connecting piece oiling machine, which comprises a worktable and coating modules. A rectangular through hole is formed in the middle of a top plate of the worktable. In the adjustable conveying pipeline connecting piece oiling machine, by arranging the two coating modules,the spacing between the two coating modules can be adjusted through air cylinders, rotation of the two coating module can be controlled through a motor, mounting frames between adjacent first mountingdiscs and second mounting discs are separated from each other through the air cylinders and torsional springs between the mounting frames and connecting seats, the outer side wall of a pipeline connecting piece is oiled through outer coating rollers, and elastic coating rollers on the mounting frames make contact with the inner side wall of the pipeline connecting piece, so that the inner side wall and the outer side wall of the pipeline connecting piece are both oiled, the rotating mounting frames are utilized to drive elastic coating sleeves to rotate to oil the inner side wall of the pipeline connecting piece, and thus the oiling efficiency of the inner side and the outer side of the pipeline connecting piece is improved advantageously.

Description

technical field [0001] The invention relates to the technical field of pipeline oiling, in particular to an adjustable oiling machine for connecting pieces of transmission pipelines. Background technique [0002] The common corrosion of valve pipes is the corrosion of carbon steel and low carbon alloy steel. Usually, the connection between the pipeline and the pipeline valve is mostly connected by pipeline connectors. Regardless of whether the valve pipeline is laid on the ground, underground or underwater (including the seabed), it is subject to external air, soil, water (especially seawater) on the pipeline. Corrosion of the outer wall of the connector, and corrosion of the inner wall of the pipeline connector by the conveying medium. Therefore, while the pipeline connector is being processed, it is necessary to oil the inner and outer walls of the pipeline connector, so as to prolong the service life of the pipeline connector. [0003] However, some of the existing pipe...

Problems solved by technology

[0003] However, some of the existing pipeline connectors are manually coated during the oiling process, and the inner and outer walls are processed sequentially, which reduces the oiling efficiency of the pipeline connectors, and some devices that use mechanical processing , the pipeline connector cannot be oiled during use, and the specification of the coating roller needs to be adjusted according to the inner and outer diameters of the pipeline connector, which reduces the processing efficiency of the pipeline connector
