Description

High-strength pipeline plugging air bag traction device

Technical Field

The invention relates to the technical field of pipeline plugging air bags, in particular to a high-strength pipeline plugging air bag traction device.

Background

The pipeline plugging air bag is expanded by an inflation method by utilizing the pipeline plugging air bag made of high-quality rubber, when the gas pressure in the water plugging air bag meets the specified requirement, the water plugging air bag fills the section of the whole pipeline, and water leakage is plugged by utilizing the friction force generated by the wall of the pipeline plugging air bag and the pipeline, so that the aim of quickly blocking water flow in a target pipeline section by inflation and expansion is fulfilled, and the aim of no water seepage is fulfilled.

Municipal drainage pipe is through long-time operation or receive the external load effect, and various structural and functional damage phenomena have appeared in some pipelines, and in order to guarantee the normal operating that the drainage set up, damaged pipeline is waited to restore or change urgently. As the conventional grooving construction is adopted for repairing or replacing the pipeline, a plurality of adverse effects are brought, and the pipeline trenchless repairing technology is gradually the mainstream construction technology for repairing the pipeline in future. In the non-excavation construction process, the pipeline to be repaired needs to be plugged, and air bags are mostly used for plugging.

Pipeline shutoff gasbag slides aversion in the pipeline easily at the in-process that uses, bear water pressure when great when the gasbag, very easily drop from the pipeline, bring the injury for the operation personnel, bear water pressure when not enough when the gasbag, very easily slide toward pipeline depths, lead to the gasbag difficult taking out, for example the pipeline shutoff gasbag that the publication is CN211315494U, including the gasbag body, the one end fixedly connected with ring flange of gasbag body, fixedly connected with gasbag's the trachea of advancing out on the ring flange, the net is drawn in this external still cup jointing of gasbag, and draw the net to flange dish side extension. Through adopting above-mentioned scheme, cup joint the net outside gasbag body, when needs pulling gasbag body, hold the net of hauling, gasbag body is in the net of hauling together by the pulling, the effect of force is transmitted the gasbag body again through the net of hauling, make gasbag body large tracts of land atress, avoid the effect of force only to act on in a small block region on the gasbag body, thereby make gasbag body unit area atress diminish, make the gasbag body can bear bigger power, the gasbag body is more easily pulled by the net of hauling together, and make the gasbag body not fragile when the pulling.
