Embodiment

[0023] The four-drive walking device 1 of the present invention is a three-petal overlapping ring-shaped opening and closing structure, which is composed of two three-petal overlapping and opening-closing annular plate frames 8 connected by a rotating shaft 9, and the rotating shaft 9 is connected to the annular plate by bolts. Frame 8, and a copper pad is provided at the joint to prevent wear and tear when the ring structure is opened and closed. The hook-type quick clamping joint 6 with locking spring 5 is installed at the opening and closing opening of the ring plate frame 8, and is used to quickly place the four-drive traveling device 1 on the pipe section to be repaired. Between the annular plate frames 8, a cylindrical guide rod 14 and a rack 15 supporting the positioning and power transmission of the transverse traveling device 3 are installed, and a support rod 10 threaded for stabilizing the ring structure is also installed. The reduction gear group 7 connecting the m...

Abstract

The invention relates to an airtight automatic de-rusting machine for a pipeline repaired port. The airtight automatic de-rusting machine is especially designed for solving the problems caused by a manual open type sandblast de-rusting operation for the pipeline repaired port. A main structure of the de-rusting machine is formed by a four-driving running device and a horizontal running device which are used for supplying motive power to the peripheral stepping and horizontal moving of the automatic de-rusting machine and executing a polishing operation. The airtight automatic de-rusting machine can automatically run according to a preset control program and can finish the surface treating operation for the pipeline; the surface of the pipeline after being treated completely meets the grade demand; the used time is short; and the efficiency is high. The airtight automatic de-rusting machine can be used for successfully solving a series of problems caused in the manual open type sandblast de-rusting operation; the labor intensity is greatly reduced; the environmental pollution is avoided; the sand material is saved; and the processing quality of the repaired port is fully ensured.

Description

technical field [0001] The invention relates to a closed automatic derusting machine for pipeline joint sealing, which belongs to the technical field of oil and gas pipeline construction, and is an airtight automatic derusting machine for pipeline surface treatment in the process of pipeline joint joint anticorrosion. Background technique [0002] With the continuous and rapid development of my country's energy industry, long-distance oil and gas pipelines have become an important way of energy security. In the construction of oil and gas pipelines, in order to ensure the service life of the pipeline, the anticorrosion of the joint section of the pipeline is particularly important, and the quality of the surface treatment of the pipeline in the anticorrosion process directly affects the service life of the anticorrosion layer. In the current pipeline construction, the surface treatment of the pipeline in the mending section is manual operation and open sandblasting, which br...
