A pneumatic telescopic pipe cleaner

Abstract

The invention relates to the technical field of oil field pipelines, and in particular to a pneumatic telescopic type inside-pipe sweeper. The sweeper comprises a fixed frame, a sweeping plate, a front baffle, a rear baffle, two cylinders and two brackets. The sweeper is connected with a pipeline internal clamp telescopic disc through the fixed frame. The sweeping plate is clamped between the front baffle and the rear baffle. The rear baffle and the two brackets are welded into a whole. Stop pieces are welded to the two ends of the rear baffle and form a U-shaped groove together with a protruding part at the end of the rear baffle. The U-shaped groove is clamped on the two sides of the pipeline internal clamp telescopic disc. The fixed frame is fixedly connected with the two cylinders. Piston rods of the two cylinders are sleeved with the two brackets respectively. The distance between the sweeping plate and the inner wall of a pipeline can be adjusted when pistons rise and fall. When a pipeline internal clamp walks in the pipeline, sediment on the lower portion of the pipeline is pushed to a pipe opening through the sweeping plate to be removed out of the pipeline. The pneumatic telescopic type inside-pipe sweeper has the beneficial effects of being low in labor intensity, high in efficiency, good in sweeping effect, small in damage to inner anti-corrosion layers, healthy, environment-friendly, and the like.

Description

technical field [0001] The invention relates to the technical field of oilfield pipelines, in particular to a pneumatically telescopic in-pipe cleaner. Background technique [0002] In long-distance pipeline projects, for pipelines lined with an anti-corrosion layer, the inner wall should be cleaned after assembly and welding to prevent the internal anti-corrosion layer from being damaged due to excessive accumulation of sand, dust, welding slag and other debris in subsequent construction. damage, affecting the construction quality. At present, medium and small-diameter pipelines are cleaned by air blowing. For large-diameter pipelines, people drill into the pipeline and use tools such as brooms and mops to clean them manually. The efficiency is low and the cleaning effect is poor.

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a pneumatic telescopic pipe cleaning device to overcome the high labor intensity, low efficiency, and high labor intensity and low efficiency of the manual cleaning method currently used for large-diameter pipes in areas with large sandstorms. The cleaning is not clean, the internal anti-corrosion layer is damaged, and the health of the cleaning personnel is affected, etc.
