Pipeline outer surface anti-rust oil smearing device

Abstract

The invention discloses a pipeline outer surface anti-rust oil smearing device, and relates to the technical field of pipeline processing. The pipeline outer surface anti-rust oil smearing device comprises a pipeline and a supporting hanger plate; the supporting hanger plate is slidably connected with a frame through a sliding part, and the frame is provided with a smearing device for smearing theouter wall of the pipeline; the smearing device comprises an oil storage tank, four pairs of linkage plates and a lantern ring, wherein the oil storage tank is fixedly connected with the wall of theframe, the four pairs of linkage plates are distributed in an annular array mode, and the lantern ring is arranged on the outer wall of the pipeline in a sleeving mode; the outer wall of the lantern ring is fixedly connected with two connecting plates, the ends of the two connecting plates are rotationally connected with connecting shafts, and shaft arms of the two connecting shafts are fixedly connected with abutting parts; a driving mechanism for the lantern ring to rotate is arranged on the supporting hanging plate; and the smearing device further comprises a wiping device for wiping the outer wall of the pipeline and a pressurizing device for pressurizing the oil storage tank. According to the pipeline outer surface anti-rust oil smearing device, through cooperation of the structures,the outer wall of the pipeline can be subjected to oil spraying and smearing through mechanical movement.

Description

technical field [0001] The invention relates to the technical field of pipeline processing, in particular to a device for applying antirust oil on the outer surface of pipelines. Background technique [0002] In the process of building construction, it is often necessary to use some large-diameter pipes, such as sewage pipes and natural gas pipes. These pipes need antirust treatment before use. Antirust treatment generally involves coating A layer of anti-rust oil is used to ensure that the surface of these pipes will not rust, so as to improve the service life of the pipes. [0003] The oiling method is usually to immerse the pipeline directly in the anti-rust oil, take out the pipeline after a period of time, and the oiling process on the surface of the pipeline can be completed, but in this scheme, due to the long length of some pipelines, it is not convenient to use the overall immersion of the pipeline In addition, it is carried out manually, and its oiling efficiency ...
