Automatic inflating airbag for petroleum pipeline overhauling

Abstract

The invention discloses an automatic inflating airbag for petroleum pipeline overhauling. The automatic inflating airbag structurally comprises friction rings, a shell, an automatic inflating device,a main air inlet pipe, an auxiliary air inlet pipe and a rope tying ring. Two or more friction rings are arranged and distributed on the surface of the shell at equal intervals, the shell and the friction rings are integrally arranged, the automatic inflating device is arranged on the shell and communicated with the shell, the main air inlet pipe and the auxiliary air inlet pipe are fixedly arranged at the end, away from the shell, of the automatic inflating device, and the main air inlet pipe and the auxiliary air inlet pipe are communicated with the automatic inflating device. The rope tyingring and the automatic inflating device are mounted at the same end of the shell. According to the automatic inflating airbag, under the combined action of a compression inflating device, an air backflow preventing device, a driving device, an auxiliary inflating device and a rotation control mechanism, the airbag can be automatically inflated, and therefore human input is reduced.

Description

technical field [0001] The invention relates to the field of maintenance equipment for oil pipelines, in particular to an automatic inflatable air bag for maintenance of oil pipelines. Background technique [0002] In the oil industry, it is necessary to lay long pipelines for oil transportation, but because most of the oil pipelines are laid in relatively harsh environments, there are often leakages, ruptures, etc., requiring staff to repair and weld the pipelines in time , but in the repair process, the oil in the entire oil pipeline needs to be pumped clean, the workload is heavy and the operation is troublesome. [0003] The prior art airbags for maintenance of oil pipelines require manual operation to inflate the airbags, which cannot meet the actual application requirements. Contents of the invention [0004] Aiming at the deficiencies in the prior art, the present invention is realized through the following technical solutions: the automatic inflatable air bag for ...
