Abstract

The invention relates to an expanding type pipe plugging head and a body mechanism thereof. The expanding type pipe plugging head and the body mechanism are mainly used for water plugging for transformation, emergency maintenance, dredging and the like of municipal drainage pipes. The expanding type pipe plugging head comprises an elastic plugging cap and an expanding ring, and the expanding ring is installed in the elastic plugging cap, and is driven by a dilatation mechanism to generate dilatation deformation in the radial direction. The elastic plugging cap is plugged into the portion, close to a pipe opening, of a pipe through dilatation deformation of the expanding ring. The expanding type pipe plugging head has the high universality, can adapt to plugging operation of the pipes with different pipe diameters, is convenient to use, large in plugging force and reliable in plugging, and has high market value and using value.

Description

technical field [0001] The invention relates to an expandable pipe plugging head and its main body mechanism, which are mainly used for water blocking such as reconstruction, emergency repair and dredging of municipal drainage pipes. Background technique [0002] In municipal engineering, especially in the construction of sewage pipelines, it is often necessary to partially block the sewage pipelines and pump out the water in the sewage pipelines so that construction workers can enter the sewage pipelines to work. The traditional sewage pipe plugging method is to use a plugging air bag to block water. [0003] The working principle of the plugging airbag for water blocking is to use the pipe sealing airbag made of high-quality rubber to inflate it by inflation. The frictional force generated by the pipeline blocking air bag wall and the pipeline blocks the water leakage, so as to achieve the purpose of no water seepage in the target pipe section. But the airbag must be blo...
