Description

Technical Field

[0001] The utility model relates to the field of gas pipeline maintenance equipment, in particular to a gas pipeline maintenance and plugging device. Background Art

[0002] Gas pipelines are infrastructure used to transport natural gas, liquefied petroleum gas and other gases. They are an important part of the urban gas supply system. The safe operation of gas pipelines is crucial to ensuring the living needs of urban residents and industrial production.

[0003] At present, when a gas pipeline needs to be repaired, it is necessary to use a maintenance and plugging device to seal the pipe mouth of the gas pipeline. When the existing gas pipeline maintenance and plugging device is in use, the fixing plate is first fixed on the pipe to be blocked, and then the connecting plate is manually pushed forward and backward, and the fixing box is placed from top to bottom at the center of the fixing plate. At this time, the moving rod with the sealing plate can be inserted into the pipe. When the sealing plate is inserted into the pipe to a certain depth, the pull rod is manually pulled upward, and the pull rod brings the pull plate upward together. At this time, the block in the connecting pipe is tightly fitted with the connecting pipe, thereby blocking the pipeline. However, when the existing gas pipeline maintenance and plugging device is in use, manual operation requires multiple steps, and it is necessary to push the connecting plate forward and backward, place the fixing box up and down, insert the moving rod, pull the pull rod, etc. The operation is cumbersome and may lead to low operating efficiency. In addition, manual operation makes it difficult to ensure that the sealing effect of each plugging is consistent.
