Description
Technical Field
The utility model relates to an gasbag especially relates to a novel gasbag of pipeline construction.
Background
The plugging air bag is called a water plugging air bag or a water closing plug, is a tool for plugging a pipeline during pipeline maintenance and testing, and has the working principle that: the pipeline plugging air bag made of rubber is expanded through an inflation method, when the gas pressure in the water plugging air bag meets the specified requirements, the water plugging air bag fills the section of the whole pipeline, water leakage is plugged through the friction force generated between the wall of the pipeline plugging air bag and the pipeline, and therefore the purpose that no water leaks in a target pipeline section is achieved. The plugging air bag is simple to operate, has good ageing resistance and long service life, and the plugging air bag used for plugging the pipeline at present has the risk of being pushed out by water pressure, so that great risk is brought to underground operators.
SUMMERY OF THE UTILITY MODEL
The utility model provides a solve the not enough of above-mentioned technique, provide a novel gasbag of pipeline construction, effectively prevented that the shutoff gasbag from being released by water pressure, strengthened the fixed of shutoff gasbag.
The utility model discloses technical scheme: the utility model provides a novel gasbag of pipeline construction, includes shutoff gasbag, shore post and supporting shoe, the shutoff gasbag is aerifyd the back front end and is umbrella type structure, and the rear end is the cylinder structure, shutoff gasbag center is provided with and is used for adding the fixed through-hole that plugs, shore post and the through-hole phase-match that plugs, shore post is the cylinder type setting, shutoff gasbag rear end is connected with the supporting shoe, the supporting shoe center is provided with fixing hole, the fixing hole is provided with the internal thread to shore post phase-match with the shore, shore post periphery matches fixing hole and is provided with the external screw thread, but this supporting shoe threaded fixation shore post, shore post is provided with the boss along the circumference outward towards shutoff gasbag one end, the boss can shore in the outer circumference of shutoff gasbag.
The utility model discloses a further setting: and the rear end of the supporting block is also provided with a fixing screw.
The utility model discloses a further setting: the front end of the jacking column is in arc transition.
By adopting the technical scheme, the plugging air bag with the umbrella-shaped structure can reduce certain water pressure, can divide water pressure to two sides of the plugging air bag, the plugging air bag can fix the jacking column after being inflated, the cylinder structure end can be fixed in a pipeline, the side wall of the cylinder structure can increase the contact area with the pipeline, the plugging pressure is enhanced, the umbrella-shaped structure at the front end and the front end of the jacking column in arc transition arrangement can divide water pressure, the forward pressure of water pressure is reduced, the supporting block is further designed at the rear end of the plugging air bag, and a boss is arranged on the supporting block towards the outer edge of one end of the plugging air bag, because the stress surfaces at two sides of the umbrella-shaped structure at the front end of the plugging air bag are smaller, the boss can effectively prop on the outer circumference of the plugging air bag, and meanwhile, the.

Detailed Description
The novel air bag for pipeline construction shown in figures 1 to 3 comprises a plugging air bag 1, a top bracing column 2 and a supporting block 3, the front end of the plugging air bag 1 is of an umbrella-shaped structure 4 after being inflated, the rear end is of a column structure 5, a plugging through hole 12 for plugging and fixing is arranged in the center of the plugging air bag 1, the propping column 2 is matched with the plugging through hole 12, the propping column 2 is arranged in a cylinder shape, the rear end of the plugging air bag 1 is connected with a supporting block 3, a fixing through hole is arranged in the center of the supporting block 3, an internal thread is arranged in the fixing through hole, and is matched with the top bracing column 2, the periphery of the top bracing column 2 is matched with a fixed through hole and is provided with an external thread, the supporting block 3 can be fixed on the jacking column 2 in a threaded manner, the jacking column 2 is provided with a boss 6 towards one end of the plugging air bag 1 along the circumference, and the boss 6 can be jacked on the outer circumference of the plugging air bag 1.
The rear end of the supporting block 3 is also provided with a fixing screw 7.
The front end of the supporting pillar 2 is in arc transition.
The plugging air bag 1 adopting the umbrella-shaped structure can reduce certain water pressure, can shunt the water pressure to two sides of the plugging air bag 1, the plugging air bag 1 can fix the supporting column 2 after being inflated, the end of the cylinder structure 5 can be fixed in the pipeline 11, the side wall of the cylinder structure 5 can increase the contact area with the pipeline 11, the plugging pressure is enhanced, the umbrella-shaped structure 4 at the front end and the front end of the supporting column 2 which is arranged in the arc transition mode can shunt the water pressure, the forward pressure of the water pressure is reduced, the supporting block 3 is further designed at the rear end of the plugging air bag 1, and the boss 6 is arranged at the supporting block 3 towards the outer edge of one end of the plugging air bag 1 along the circumference, because the stress surfaces at two sides of the umbrella-shaped structure 4 at the front end of the plugging air bag 1 are smaller, the boss 6 can be effectively propped on the outer circumference.
