Problems solved by technology

[0002] At present, in the process of repairing submarine pipeline leaks, in order to peel off the outer casing smoothly, the usual construction method is to cut the outer pipe circumferentially and longitudinally by underwater electro-oxygen cutting, but this cutting method has safety hazards. Hidden dangers, the pipeline needs to be stopped and cleaned before cutting to prevent unsafe factors during the construction process

Embodiment Construction

[0010] Such as figure 1 As shown in the front working schematic diagram of the steel pipe longitudinal seam cutting machine, the steel pipe longitudinal seam cutting machine is fixed to the pipeline 9 by the ring block fixing device 6. The hydraulic motor 1 is connected with the external hydraulic station, and the power is output through the transmission gear box 2; the transmission gear box 2 It is equipped with a clutch device and a feed device. The feed device acts on the milling cutter 3 to control the feed of the milling cutter 3 in the axial direction of the pipeline 9 for cutting operations. When the milling cutter 3 cuts through the outer pipe of the pipeline 9, press The lower clutch device controls the climbing wheel 7 to crawl axially along the pipeline 9 on the chain 4, and the climbing wheel 7 drives the cutting machine to move at a constant speed on the guide rail 8, thereby completing the longitudinal cutting task.

Abstract

The invention provides a steel pipe vertical seam cutting machine, which consists of a milling cutter 3, a press chain device 5, a speed change gear box 2, a hydraulic motor 1, a guide rail 8, a climbing wheel 7, a chain 4 and an annular plate fixing device 6. The device adopts the mechanical cutting method, eliminates the potential safety hazard for stripping off an outer pipe by oxy arc cutting, omits the cleaning work of an inner pipe, simplifies the construction process, further improves the construction speed of the offshore pipeline leak source restoration, and lowers the construction cost.

Description

Technical field [0001] The invention belongs to the innovation of an outer pipe stripping device in the process of repairing leaks of submarine pipelines in ocean engineering. Background technique [0002] At present, in the process of repairing leaks in submarine pipelines, in order to smoothly peel off the outer casing, the usual construction method is to cut the outer pipe circumferentially and longitudinally through underwater electro-oxygen cutting, but this cutting method has safety Hidden hazards, the pipeline needs to be shut down and cleaned before cutting to prevent unsafe factors in the construction process. Summary of the invention [0003] In order to ensure the safety of underwater construction, the present invention provides a steel pipe longitudinal seam cutting machine device. The device adopts a mechanical cutting method, which eliminates the hidden safety hazards of underwater electro-oxygen cutting when peeling off the outer casing, eliminates the need to clea...
