Referring to fig. 3 and 4, the use process of the double-tile plugging device comprises a preparation stage and a use stage, wherein the preparation stage specifically works as follows: firstly, a proper plugging position is determined according to actual conditions, and a pipe fitting A specially matched with the double-tile plugging device for plugging is manufactured. And then sleeving the manufactured pipe fitting on the pre-plugging pipeline B and welding, and tapping the pre-plugging pipeline by using a pipeline pressure tapping machine so as to cut off the pre-plugging pipeline. And finally, the double-tile plugging device is sent into the cut-off pre-plugged pipeline through the hole by using the plugging device, and the preparation stage is completed.

After the preparation stage of the double-tile plugging device is completed, the use stage can be started. The specific work in the use phase is as follows: firstly, the screw rod is rotated, so that the connecting rod in threaded connection with the lower end of the screw rod moves downwards. The connecting rod pushes the supporting device downwards, so that two support arms in the supporting device move, and the first sliding block and the second sliding block at the end parts of the two support arms are pushed to move outwards. The tile blocks on the two sides of the supporting device move outwards under the pushing of the first sliding block and the second sliding block until the tile blocks are abutted against the ends of the two ends of the cut pipeline, the screw rod stops rotating at the moment, and the double-tile block plugging device completes the plugging work of the pipeline. After the maintenance and replacement operations of the pipeline accessories are finished, the screw rod is rotated reversely to drive the connecting rod to move upwards, so that the support arm drives the first sliding block and the second sliding block to move inwards, the plugging pads on the two sides of the supporting device move inwards, and plugging of the pipeline is removed.

The double-tile block plugging device provides power by rotating the lead screw, and the two plugging tiles move outwards through the mechanical transmission of the connecting rod, the supporting arm, the first sliding block and the second sliding block to complete the pipeline plugging work. This two tile plugging device is rational in infrastructure to adopt mechanical transmission's mode, make this two tile plugging device also accelerate the speed of pipeline shutoff when simple structure, strive for the time for subsequent pipeline annex maintenance and change work, reduced holistic time consumption, and then improve work efficiency.

Meanwhile, the purchasing cost of the components of the double-tile plugging device is low, so that the manufacturing cost of the double-tile plugging device is low, and the construction cost of maintaining and replacing the pipeline accessories is further reduced.

In order to facilitate the rotation operation of the screw rod 5, as an improvement of the technical scheme, a driving device 6 is further arranged in the double-tile plugging device, the driving device 6 is fixedly arranged at the upper end part of the framework 1 and is opposite to the position of the first mounting hole 13, and the output end of the driving device 6 is in driving connection with the upper end of the screw rod 5. The double-tile block plugging device is more stable in operation by adopting the driving device to control the rotation of the screw rod, the plugging tiles move at a constant speed, and the plugging effect of the plugging sliding block on the end of the pipeline is also improved while the impact force on the end of the pipeline is reduced. The driving device 6 can perform normal rotation and reverse rotation.

In order to improve the plugging effect and prolong the service life of the plugging tile, as the improvement of the technical scheme, two plugging tiles 4 can be designed into an arc shape, see fig. 1, each plugging tile 4 is designed into a tile 41, a rubber plate 42 and two positioning plates 43, wherein the tile 41 is designed into an arc shape, the rubber plate 42 is fixedly wrapped on the outer side surface of the tile 41, the two positioning plates 43 are arranged on each inner side surface of the tile 41 at intervals and respectively correspond to the adjacent first sliding block 33 and second sliding block 34, and the two positioning plates 43 are respectively fixedly connected with the adjacent first sliding block 33 and second sliding block 34.

Through set up the rubber slab in the tile outside, when playing the impact force of alleviating plugging device to pipeline port production, also further improved this two tile plugging device's shutoff effect. Through setting up the locating plate in the tile inboard, the tile passes through the locating plate to be connected with first slider and second slider, when avoiding directly being connected with first slider and second slider, because the atress that area of contact is little to result in is concentrated, and then has prevented that the tile from taking place by the condition of first slider and second slider crush. Through setting up the locating plate, can effectually with the pressure homodisperse that first slider and second slider exerted to the tile, the phenomenon of the tile damage that avoids the atress to concentrate and lead to takes place.
