Abstract

The utility model discloses a pipeline gas plug which comprises a cylindrical gas bag, two sealing flanges serving as the end faces of the gas plug and clamping the ends of the gas bag in a surrounding mode, a plurality of supporting trundles evenly distributed on the out sides of the sealing flanges in the circumferential direction and fixedly connected with the sealing flanges and handles fixedly connected to the outer sides of the sealing flanges. The suspending end of each supporting trundle strides the circumferential edge of the corresponding sealing flange. The gas bag is cylindrical. When the gas bag is placed in a pipeline and taken out of the pipeline, the gas bag is not in contact with the wall of the pipeline, so that the gas bag is prevented from being rubbed and damaged and the service life of the gas bag is prolonged. By the adoption of the supporting trundles, the pipeline gas plug is moved, the gas plug conveniently is moved in the pipeline, and therefore the labor intensity is relieved. Meanwhile, when the pipeline gas plug is moved on the ground, the gas plug is rotated by 90 degrees and one sealing flange is erected and located on the lower side, so that the gas plug is moved through the trundles and the carrying labor intensity is relieved.

One as the stifled technological scheme of the utility model pipeline gas is improved, and between described sealing flange, is provided with and determines connecting rod, and described end of determining connecting rod is fixedly connected on described sealing flange inner side.
One as the stifled technological scheme of the utility model pipeline gas is improved, and the radial deflection amount of described air bag is less than the radial span of described support castor.
One as the stifled technological scheme of the utility model pipeline gas is improved, and is provided with the thimble assembly of Slidable telescopic between described sealing flange, and the end, two ends of described thimble assembly is fixedly connected on respectively described sealing flange inner side.
One as the stifled technological scheme of the utility model pipeline gas is improved, and described thimble assembly comprises interior loop bar, outer sleeve, orders about the elastic member that internal and external casing extends.
One as the stifled technological scheme of the utility model pipeline gas is improved, described thimble assembly comprises interior loop bar, outer sleeve, and described pipeline gas is stifled also comprises that being installed in described sealing flange inside edge shores described sealing flange and make thimble assembly maintain the strut of elongation state.
One as the stifled technological scheme of the utility model pipeline gas is improved, and described strut has the grip part that lays out flange outside, and described strut is F type or ladder-type.
One as the stifled technological scheme of the utility model pipeline gas is improved, and described air bag appearance is provided with salient point.
One as the stifled technological scheme of the utility model pipeline gas is improved, and described air bag stage casing appearance is made as latticed.
The beneficial effects of the utility model are: air bag is made as to tubular, and in the process that packs pipeline and taking-up into, air bag does not contact with tube wall, avoids frictionally damage, extend the working life of air bag.Support castor is set stifled for movement pipeline gas, thereby facilitates gas to get lodged in mobile reducing labor intensity in pipeline; Meanwhile, in the time of ground moving, erect a sealing flange and be positioned at downside can to use castor to move gas stifled thereby gas stall is crossed to 90 °, alleviate carrying labor intensity.

Embodiment
Further illustrate embodiment of the present utility model below in conjunction with accompanying drawing.
As shown in Fig. 1~Fig. 5, a kind of pipeline gas of the utility model is stifled, it comprise the air bag 10 of tubular, as the stifled end face of gas and around two sealing flanges 12 of clamping described air bag end, along described sealing flange 12 external circumferential multiple support castors 13 uniform and that be fixedly connected with described sealing flange 12, the handle 15 that is fixedly connected on described sealing flange 12 outsides, the circumferential edges of described sealing flange 12 is stepped out in the outstanding end of described support castor 13.Air bag 10 is made as to tubular, and in the process that packs pipeline and taking-up into, air bag does not contact with tube wall, avoids frictionally damage, extends the working life of air bag.Support castor 13 is set stifled for movement pipeline gas, thereby facilitates gas to get lodged in mobile reducing labor intensity in pipeline; Meanwhile, in the time of ground moving, erect a sealing flange and be positioned at downside can to use castor to move gas stifled thereby gas stall is crossed to 90 °, alleviate carrying labor intensity.
More preferably, between described sealing flange 12, be provided with and determine connecting rod 18, described end of determining connecting rod 18 is fixedly connected on described sealing flange 12 inner sides, keeps balance between sealing flange 12 to be fixedly connected with, maintain the stifled rock-steady structure of pipeline gas, avoid sealing flange 12 run-off the straights.
More preferably, the radial deflection amount of described air bag 10 is less than the radial span of described support castor 13 at sealing flange, thereby ensures that air bag 10 can saggingly not touch pipeline, thereby avoids air bag and pipeline friction.Air bag after inflation is heaved is radially greater than the radial span that supports castor, thereby blocks pipeline.
More preferably, between described sealing flange 12, be provided with the thimble assembly of Slidable telescopic, the end, two ends of described thimble assembly is fixedly connected on respectively described sealing flange 12 inner sides, ensure that between two sealing flanges 12, parallel stable connection can be stretched again, avoid excessively tightening air bag, thereby ensure that air bag and pipeline have enough surface of contact.
More preferably, described thimble assembly comprises interior loop bar, outer sleeve, orders about the elastic member that internal and external casing extends, thereby being stretched out, nature sleeve pipe avoid air bag 10 excessive sagging, after airbag aeration, can compress again and make cannula retraction make its air bag there is more surplus, after expansion, there is more multi-contact surface and amass.
More preferably, described thimble assembly comprises interior loop bar, outer sleeve, described pipeline gas is stifled also comprises that being installed in described sealing flange inside edge shores described sealing flange and make thimble assembly maintain the strut of elongation state, installation process is with strut, dismantles strut and then inflate and make air bag block pipeline after installation.
More preferably, described strut has the grip part that lays out flange outside, is convenient to clamp and dismantle strut, maintains sealing flange balance and stability and connects, and described strut is F type or ladder-type, and part is blocked top sealing flange another part as handle dismounting strut.
More preferably, described air bag appearance is provided with salient point, increases the frictional force between air bag and pipeline.
More preferably, shown in figure 5, described air bag 10 stage casing appearances are made as latticed, increase the frictional force between air bag and pipeline, can seal and prevent from seeping water with pipeline laminating thereby two ends have smooth surface.
Above disclosed is only preferred embodiment of the present utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim, still belongs to the scope that the utility model is contained.
