Description

Technical Field

[0001] The utility model belongs to the technical field of leak-blocking devices, and in particular relates to an online leak-blocking device for pipelines. Background Art

[0002] The production process of steel enterprises involves the transportation of a large number of energy media, including gas (blast furnace gas, converter gas, coke oven gas), industrial water, ammonia, coal powder, oxygen, nitrogen, argon, compressed air and other pipelines. During the production process, pipelines may leak locally, especially when transporting mediums with particles such as blast furnace gas, converter gas, and coal powder. The wear of particles makes it easier for pipelines to wear and leak. Leakage poses a great threat to normal production and even personnel safety.

[0003] There are generally two ways to deal with energy medium pipeline leakage. One is to stop the medium transportation of the pipeline and then release the pressure. After purging, weld the leaking point to restore it, and then resume medium transportation. However, it is only applicable to individual small systems or parts that have little impact on production. The second is to be adopted when the energy medium transportation cannot be stopped or stopping the energy medium transportation has a great impact on production. That is, first weld a nut or a short wire at the leaking point, and then install a screw on the nut or install a valve on the short wire to achieve the purpose of plugging the leak. However, this method is not easy to install because the medium is under pressure, which increases the labor intensity of the staff and the plugging effect is not good.

[0004] The patent (CN215763958U) discloses a pipeline emergency plugging device. First, hold the handle to drive the support frame close to the pipeline, start the lifting hydraulic press, the lifting hydraulic press drives the pressure plate to descend, the pressure plate drives the fixed block 1 and the connecting block to descend, the fixed block 1 is close to the outer wall of the pipeline, the movable plate descends to drive the fixed column and the movable rod to move, and then drives the clamping plate to clamp the pipeline. At the same time, the spring 1 is compressed, the support plate is placed under the pipeline, and the push rod on the nut is pushed. The nut drives the support plate to fix the fixed block 2 under the pipeline. The fixed block 1, the fixed block 2 and the clamping plate together form a circular structure, which seals the pipeline and fixes the device as a whole on the pipeline. This design is relatively complex, and the device and personnel are not easy to operate, so it is difficult to implement. Utility Model Content

[0019] In order to more clearly describe the present invention, the present invention is further described below in conjunction with specific embodiments. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0020] like Figure 1~2The pipeline online plugging device shown includes a screw rod 1, a support assembly and a fixing assembly. The screw rod 1 is used to pass through the leaking point of the pipeline; the support assembly is arranged at the top end of the screw rod 1 and is used to support and fix the screw rod 1 on the inner wall of the pipeline; the fixing assembly is arranged at the bottom end of the screw rod 1 and is used to fix the screw rod 1 outside the pipeline.

[0021] The support assembly includes a spring buckle 4, a fixed shaft 5, a movable rod 6 and a slot 7. The movable rod 6 is connected and fixed to the screw rod 1 through the fixed shaft 5. The number of movable rods 6 of the utility model is 2, which can be opened to rotate 180 degrees. The screw rod 1 is provided with a spring buckle 4, which includes a plug screw 8, a spring 9 and a marble 10. The marble 10 is arranged at the top of the spring buckle 4, the plug screw 8 is arranged at the bottom of the spring buckle 4, and a spring 9 is arranged between the plug screw 8 and the marble 10. The movable rod 6 is provided with a slot 7 matching the spring buckle 4.

[0022] A fixing assembly is provided at the bottom end of the screw rod 1, and the fixing assembly includes a nut 2 and an arc-shaped cover plate 3. Both the nut 2 and the arc-shaped cover plate 3 pass through the screw rod 1. The nut 2 is provided at the bottom end of the screw rod 1, and an arc-shaped cover plate 3 is provided on the screw rod 1 between the nut 2 and the pipe. To facilitate holding the pipe, the inner arc circle of the arc-shaped cover plate 3 is close to the outer wall of the pipe.
