Description

Technical Field

[0001] The present invention belongs to the technical field of pipeline lifting equipment, and particularly relates to a lifting device for anti-corrosion pipeline construction. Background Art

[0002] Pipelines are usually used to transport gases or liquids. Most pipelines for transporting oil and gas are in complex soil environments, and the transported media are mostly corrosive. Therefore, both the inner and outer walls of the pipelines may be corroded. Once the pipeline is corroded and perforated, it will cause oil and gas leakage, not only interrupting transportation, but also polluting the environment, and even possibly causing fires and hazards. Therefore, an anti-corrosion coating is usually prepared on the pipeline during pipeline anti-corrosion construction. However, since the pipeline is usually a cylindrical structure, it is inconvenient to apply the anti-corrosion coating.

[0003] When constructing an anti-corrosion pipeline, it is necessary to move the pipeline under construction.

[0049] The operation steps of this embodiment are as follows: (1) Grasp and lift the pipe 10: Start the motor 204 to rotate forward. The output shaft of the motor 204 drives the first gear 201 to rotate. The first gear 201 drives the third gear 217 to rotate. The third gear 217 drives the second pulley 216 to rotate. The first steel wire rope 210 on the second pulley 216 bypasses the first pulley 212 on the first rotating shaft 211 to drive the lifting mechanism to move downward. The two sliding rods 502 slide downward in the vertical direction on the two second support columns 9. Due to the weight of the lifting mechanism itself, during the downward movement of the lifting mechanism, the two claw hooks 509 first contact the outer circumferential side wall of the pipe 10. After the lifting mechanism continues to descend, the two claw hooks 509 move to the inner circumferential side wall of the pipe 10. The two claw hooks 509 clamp the inner circumferential side wall of the pipe 10, and the eighth spring 508 is compressed.

[0050] (2) Translating the pipeline 10: The motor 204 rotates in reverse, the first steel wire rope 210 is lifted by the lifting mechanism, the two sliding rods 502 slide upward in the vertical direction on the two second support columns 9, and the two sliding rods 502 slide to be clamped with the first clamping plate 318.
