Problems solved by technology
Since the outer wall of the oil and gas long-distance pipeline is covered with anti-corrosion medium, it has good bonding strength, so that the removal (stripping) of the anti-corrosion layer at the cutting or welding point has become the main problem affecting the construction progress.
In the current construction work, the method of manual stripping is usually not only slow, but also the stripping effect is not good.

Embodiment
[0024] Embodiment: Take a crawler-type large-diameter pipe outer anti-corrosion layer stripping machine that can remove the anti-corrosion layer on the surface of a steel pipe with a diameter of 1016 mm as an example to further illustrate. The weight of the whole machine is 75 kg.
[0025] The crawler-type large-diameter pipeline external anti-corrosion layer stripping machine is mainly composed of a left side plate 1, a right side plate 10, a motor 4, a clutch reducer 9, a walking mechanism, a chain tensioning mechanism, a roller brush lifting mechanism, a roller brush transmission mechanism, a roller Composed of brush connection mechanism.
[0026] refer to figure 1 . The left side plate 1 is parallel to the right side plate 10. On one end of the left side plate 1 and the right side plate 10, a motor base plate 2 is fixed on the plane, a motor 4 is fixed on the motor base plate 2, and a power output shaft of the motor 4 is fixed with Drive pulley 5. The driving pulley 5 i...

The invention relates to a crawler-type large diameter pipeline external anticorrosive coating peeling machine used for peeling the external anticorrosive coating of the pipeline. In the peeling machine, two electric motors are separately arranged on one end of a left side plate and one end of a right side plate; a driven pulley is connected with a clutch reducer and a walking mechanism through adrive belt; crawler-type chains are arranged among a walk driving sprocket, a tension sprocket and a walking wheel; a roller brush lifting mechanism guide pillar is fixed on a guide pillar support seat; the guide pillar penetrates through a lifting upper hole; a roller brush drive mechanism has a peeling pulley gear, a driving gear and a brush shaft stationary gear between two parallel side plates of a gear box, the peeling pulley gear is meshed with the driving gear; and the driving gear is meshed with the brush shaft stationary gear. A roller brush is fixed at the center hole of the brush shaft stationary gear. The peeling machine can be used to effectively peel the external anticorrosive coating of the pipeline with the diameter of 219-1219mm, the cleaning and operating speed is 3m / min. A roller brush with the diameter of 110mm and the width of 120mm is used for peeling, and the peeling roller brush shaft can be fixed in the middle part or outside of the peeling machine to perform peeling operation.
Description
technical field [0001] The invention relates to the technical field of mechanical equipment manufacturing, in particular to a peeling machine for the outer anti-corrosion layer of oil and gas long-distance pipelines, which is a crawler-type large-diameter pipeline outer anti-corrosion layer stripping machine, which is used for the construction of long-distance oil and gas pipelines and emergency repair pipelines. necessary mechanical equipment. Background technique [0002] Since the 1990s, for the anticorrosion of long-distance oil and gas pipelines, three-layer polyethylene (PE) external anticorrosion technology has been adopted. The outer wall of the long-distance oil and gas pipeline is wrapped with an anti-corrosion layer, that is, on the outer wall of the long-distance oil and gas pipeline, there are fusion-bonded epoxy powder, PE adhesive and polyethylene anti-corrosion medium from the inside to the outside, which are cured on the surface of the steel pipe by thermal ...
