Pipeline rust removing device applied to shipbuilding

Abstract

The invention relates to a pipeline rust removing device applied to shipbuilding. The pipeline rust removing device comprises a base plate; the base plate is provided with a clamping device used for clamping a pipeline; the upper end of the clamping device is provided with a grinding device used for grinding the pipeline; the two ends of the grinding device are each provided with a lifting devicewhich is used for driving the grinding device to be lifted up and down so that the grinding device adapts to the height of the clamping device; a telescopic cylinder cooperates with a fixing plate sothat a supporting rod on the fixing plate can be used for supporting the inner wall of the pipeline; by arranging a rubber head, damages caused by a supporting component to the pipeline are reduced; meanwhile the supporting component and a fixing adhesive plate cooperate with each other for support, so deviation of the pipeline is prevented in a machining process, and the machining precision is guaranteed; a supporting plate positioned at the end of a rotating motor can slide and simultaneously cooperates with a lifting cylinder and a horizontally-moving motor so that the pipeline rust removing device can be flexibly applied to various pipelines which are different in size; and the pipeline rust removing device is wide in applicability.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a shipbuilding pipeline derusting device. Background technique [0002] Because marine pipelines are often in contact with water, in order to make the inner and outer walls of the pipeline and the steel structure have good cleanliness and roughness, it is necessary to carry out pretreatment such as rust removal on the surface of the steel structure on the inner and outer walls of the pipeline steel. It can be seen that the importance of rust removal, in view of the particularity of the hydraulic metal structure, such as large size, and the construction environment is basically open-air, etc., the method of sand blasting is still used at this stage, although spraying Sand derusting has low cost and is easy to operate, but sandblasting derusting produces huge dust pollution, which will cause great harm to the physical and mental health of operators.
