[0002] Gas engineering not only refers to natural gas engineering, but also includes liquefied petroleum gas, coal gas, heavy oil cracking gas, etc. We use natural gas more now, so generally speaking, gas engineering now refers to natural gas engineering. The scope of gas engineering is relatively wide. Large infrastructure projects, such as: gate stations, compressed gas stations, storage tanks, etc. General civil engineering includes: community gas pipe networks, urban gas pipe networks, gas pressure regulating stations, and indoor gas pipeline installations in buildings. When carrying out gas engineering installations, pipeline plugging devices are often required to seal the uncompleted pipelines to prevent dust and sundries from entering the pipeline interior, so as to facilitate subsequent connection and expansion of the pipelines.

[0003] For example, the utility model with the application number CN202323309227.8 provides a pipeline plugging device for gas engineering. This utility model has a simple structure and is easy to use. Through the cooperation of the fastening screw and the arc-shaped clamping plate, the installation and disassembly of this device can be quickly realized, improving the installation and disassembly efficiency and reducing the physical labor of the operators. At the same time, with the cooperation of the elastic telescopic rod and the arc-shaped support plate, pipelines with different diameters can be plugged, improving the applicability of this device and bringing convenience to use; however, the existing pipeline plugging devices have poor firmness and stability during installation, easily leading to loosening of the device in the subsequent process, thus affecting the plugging effect of the gas pipeline.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a pipeline plugging device for gas engineering installation is provided. Content of the Utility Model

[0005] The purpose of the utility model is to provide a pipeline plugging device for gas engineering installation to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A pipeline plugging device for gas engineering installation, including a plugging frame and a limiting component. A side slot is opened on the side surface of the plugging frame, and the limiting component for increasing the installation firmness is arranged inside the side slot. The limiting component includes a limiting plate, a rubber sheet, an adjusting rod, a connecting block, and an adjusting threaded rod. A rubber sheet is arranged on the surface of the limiting plate, and an adjusting rod is rotatably installed at the rear side of the limiting plate. The end of the adjusting rod is connected with a connecting block through a rotating shaft, and an adjusting threaded rod is arranged at the upper end of the connecting block.

[0007] Furthermore, the limiting plates and rubber sheets are arranged in four groups in an annular distribution about the vertical center line of the blocking frame, and the number of the limiting plates and the number of the side slots are consistent.

[0008] Furthermore, the shape of the rubber sheet is a convex rectangle, and the limiting plate and the rubber sheet are tightly fitted.

[0009] Furthermore, a limiting rod is provided at the lower end of the connecting block, and the limiting rod and the connecting block are vertically distributed.

[0010] Furthermore, the lower end of the blocking frame is connected to a connecting plate, and the lower end of the connecting plate is connected to a blocking bag, and an air pipe is installed on the surface of the blocking bag.

[0011] Furthermore, a mounting frame is installed on the upper end of the blocking frame, and the mounting frame is in the shape of a Chinese character "匚".

[0012] Furthermore, a fixing assembly for connecting with the pipeline is arranged on the inner side of the mounting frame, and two groups of the fixing assembly are symmetrically arranged about the vertical center axis of the mounting frame.

[0013] Furthermore, the fixing assembly includes a fixing plate and a fixing threaded rod, and the surface of the fixing plate is connected to the fixing threaded rod.

[0014] The utility model provides a pipeline plugging device for gas engineering installation, which has the following beneficial effects:

[0015] 1. The utility model contacts the limit plate and the rubber sheet inside the pipeline under the thrust of the adjusting rod. The convex rubber sheet is deformed under pressure, so that the friction between the rubber sheet and the inner wall of the gas pipeline is increased, thereby increasing the installation firmness of the device. One side of the adjusting rod adjusts the angle as the connecting block rises and falls, thereby adjusting the position of the limit plate and providing a supporting force for the limit plate. When the adjusting threaded rod rotates, the connecting block is driven up and down to adjust the angle of the adjusting rod, but the connecting block is not driven to rotate.

[0016] 2. The utility model can directly block the inside of the gas pipeline by inflating the blocking bag under the action of the gas pipe. The mounting frame is used for installing the fixed components. The mounting frames on both sides and their corresponding fixed components are used for re-limiting the device at the pipe mouth of the gas pipeline. The fixed threaded rod rotates to control the fixing plates in the single group of mounting frames to move closer, which plays a clamping role on the pipe wall, thereby completing the installation limit of the device and making disassembly and assembly easy.

[0021] The following further describes in detail the embodiments of the present utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0022] As Figure 1 shown, a pipeline plugging device for gas engineering installation includes a plugging frame 1 and a limiting component 3. A side slot 2 is provided on the side surface of the plugging frame 1. The limiting component 3 for increasing the installation firmness is arranged inside the side slot 2. Four groups of limiting plates 301 and rubber sheets 302 are annularly distributed about the vertical center line of the plugging frame 1, and the number of limiting plates 301 is the same as that of the side slots 2. The limiting component 3 includes a limiting plate 301, a rubber sheet 302, an adjusting rod 303, a connecting block 304, and an adjusting threaded rod 305. A rubber sheet 302 is arranged on the surface of the limiting plate 301. The shape of the rubber sheet 302 is a convex rectangle, and the limiting plate 301 and the rubber sheet 302 are closely attached. The limiting plate 301 and the rubber sheet 302 are in contact inside the pipeline under the thrust of the adjusting rod 303. The convex rubber sheet 302 is compressed and deformed, increasing the friction between the rubber sheet 302 and the inner wall of the gas pipeline, and increasing the installation firmness of the device. An adjusting rod 303 is rotatably installed at the rear side of the limiting plate 301. One side of the adjusting rod 303 adjusts the angle along with the lifting of the connecting block 304, thereby adjusting the position of the limiting plate 301 and providing a supporting force to the limiting plate 301 at the same time. The end of the adjusting rod 303 is connected to the connecting block 304 through a rotating shaft. A limiting rod 4 is arranged at the lower end of the connecting block 304, and the limiting rod 4 and the connecting block 304 are vertically distributed. An adjusting threaded rod 305 is arranged at the upper end of the connecting block 304. When the adjusting threaded rod 305 rotates, it drives the connecting block 304 to move up and down to adjust the angle of the adjusting rod 303, but does not drive the connecting block 304 to rotate.

[0023] As Figure 2As shown, the lower end of the blocking frame 1 is connected to a connecting plate 5, and the lower end of the connecting plate 5 is connected to a blocking bag 6. The blocking bag 6 expands after being inflated under the action of the gas pipe 7, and can directly block the inside of the gas pipeline. The gas pipe 7 is installed on the surface of the blocking bag 6. The upper end of the blocking frame 1 is installed with a mounting frame 8, and the mounting frame 8 is used for the installation of the fixing component 9, and the shape of the mounting frame 8 is a Chinese character "匚".

[0024] like Figure 3 As shown, a fixing assembly 9 for connecting to the pipeline is provided on the inner side of the mounting frame 8, and the mounting frames 8 on both sides and their corresponding fixing assemblies 9 are used for re-limiting the device at the pipe mouth of the gas pipeline, and two groups of fixing assemblies 9 are symmetrically arranged about the vertical center axis of the mounting frame 8, and the fixing assembly 9 includes a fixing plate 901 and a fixing threaded rod 902, and the surface of the fixing plate 901 is connected to the fixing threaded rod 902, and the fixing threaded rod 902 rotates to control the fixing plate 901 in a single group of mounting frames 8 to approach, thereby clamping the pipe wall, thereby completing the installation limit of the device, and easy disassembly and assembly.

[0025] In summary, the pipeline plugging device for gas engineering installation is firstly based on Figures 1 - 3 The structure shown in, during installation, one end of the blocking bag 6 is inserted into the gas pipeline, and the two mounting frames 8 are respectively located on both sides of the pipeline, and the fixing threaded rod 902 is rotated to make the fixing plate 901 close to each other, so as to clamp the pipe wall, that is, the initial installation limit of the device is completed, and then the adjusting threaded rod 305 is rotated to move it outward. When the adjusting threaded rod 305 drives the connecting block 304 to move upward, the angle of one side of the adjusting rod 303 is adjusted as the connecting block 304 is lifted and lowered, thereby adjusting the position of the limiting plate 301, so that the limiting plate 301 and the rubber sheet 302 are contacted inside the pipeline by the thrust of the adjusting rod 303, and the convex rubber sheet 302 is compressed and deformed, so that the friction between the rubber sheet 302 and the inner wall of the gas pipeline is increased, thereby increasing the installation firmness of the device, and then the blocking bag 6 is inflated through the gas transmission pipe 7 to make it expand and block inside the gas pipeline, which is easy to operate and has good sealing firmness.
