Preferably, a sealing strip is arranged on the periphery of the folded edge.

Preferably, both ends of the upper arc-shaped part and the lower arc-shaped part are provided with connecting lugs, and the connecting lugs are connected through bolts and nuts.

Preferably, both ends of the upper clamping plate are provided with upper wing plates extending outwards along the horizontal direction, both ends of the lower clamping plate are provided with lower wing plates extending outwards along the horizontal direction, the lower surface of the upper wing plate is a first sawtooth shape, the upper surface of the lower wing plate is a second sawtooth shape, and the first sawtooth shape is matched with the second sawtooth shape.

Preferably, the upper wing plate and the lower wing plate are connected by bolts.

Preferably, a groove for placing a carbon ring is formed in the periphery of the inner wall of the plugging device body.

When the hydraulic pipeline leaks, the leakage plugging device body can be quickly attached to the leakage position of the pipeline, the pipeline is wrapped by the two arc-shaped pieces in the shape of the semi-circular ring, the effect of quickly closing the damaged position of the pipeline to prevent continuous leakage is achieved, and the leakage plugging device body of the emergency leakage plugging device is connected through the bolt, so that the emergency leakage plugging device is quick and convenient to operate and suitable for emergency leakage plugging; the shell is arranged outside the leakage stopping device body, so that the double-layer leakage stopping effect can be achieved; the upper clamping plate and the lower clamping plate are provided with the air inlet holes and the air inlet valves matched with the air inlet holes, and air can be introduced between the shell and the leakage stopping device body through the air inlet valve holes, so that the pressure between the shell and the leakage stopping device body is improved, the leakage stopping device body is more attached to a pipeline, and the formed huge pressure to the pipeline also has the leakage preventing effect; the folded edges which are folded inwards are arranged on the two sides of the clamping plate, and the sealing strips are arranged on the periphery of the folded edges, so that the purpose of preventing air leakage can be achieved, and the emergency plugging device can be used for rapidly and reliably plugging the leakage position of the pipeline. The emergency plugging device has the advantages of being simple and convenient to install, free of large-scale machinery operation at a damaged position, fast in plugging effect, free of environmental pollution and good in economic benefit and social benefit.
