Description

Technical Field

[0001] This utility model relates to the field of gas pipeline sealing technology, and in particular to a temporary sealing device for gas pipeline construction. Background Technology

[0002] The installation of gas pipelines is divided into medium- and low-pressure sections, including the installation and commissioning of gas-related equipment and facilities. During the initial stages of gas pipeline installation, temporary sealing of the pipeline openings during construction breaks involved stuffing them with burlap sacks and plastic to prevent sand, water, and other debris from entering the pipeline. This approach proved ineffective, resulting in incomplete sealing, gaps, and the entry of debris that hampered subsequent pipeline construction.

[0003] Existing technologies, such as the utility model of a simple temporary sealing device for gas pipeline construction (authorization announcement number CN218000831U), have multiple advantages, including simple construction process, simple use, and ability to ensure the quality of temporary sealing of pipe openings. They do not damage the pipeline, provide a tight seal, and prevent the inflow of debris or water stains, thus improving the quality of pipeline construction. They also avoid the tedious process of purging debris from the pipe during subsequent pipeline construction, and the device can be reused.

[0004] Currently, there is a lack of a device that can conveniently seal the pipeline while simultaneously clamping it, allowing the device to be installed more stably on the pipeline.

[0005] Therefore, in order to address the above problems, a temporary sealing device for gas pipeline construction is proposed to solve these problems. Utility Model Content

[0006] This invention addresses the shortcomings of existing technologies by developing a temporary pipe opening sealing device for gas pipeline construction. This invention facilitates the sealing of the pipeline while simultaneously clamping it, allowing the device to be installed more stably on the pipeline.

[0007] The technical solution to the problem solved by this utility model is as follows: This utility model provides a temporary pipe end sealing device for gas pipeline construction, comprising: a contact cover plate connected to a threaded cylinder; a first screw threadedly connected to the threaded cylinder; a plug plate connected to an installation ring, the first screw bearing connected to the installation ring; and symmetrical guide rods, each connected to the plug plate and passing through a guide tube, the symmetrical guide tubes being connected to the contact cover plate. By using the plug plate, the contact cover plate contacts the end of the pipeline, the plug plate enters the pipeline, and its surface rubber undergoes elastic deformation, thereby sealing the pipeline.

[0008] As an optimization, the contact cover plate is provided with symmetrical convex grooves, and protrusions are respectively provided in the symmetrical convex grooves. The symmetrical protrusions are respectively connected to arc-shaped clamping rods. By using arc-shaped clamping rods, the device can be installed on the pipeline when the arc-shaped clamping rods clamp the pipeline.

[0009] As an optimization, the contact cover plate is connected to a fixed seat for each of the convex grooves, the symmetrical protrusions are connected to mounting seats, the symmetrical fixed seats are respectively bearing the central shaft of the second screw, and the symmetrical second screws are respectively threaded to the corresponding mounting seats. By using the second screw, the movement of the arc-shaped clamp is achieved when it rotates.

[0010] As an optimization, the contact cover plate is connected to a large ring, the large ring bearing is connected to a transmission bevel gear, and the symmetrical second screws are respectively connected to driven bevel gears, with the symmetrical driven bevel gears meshing with the transmission bevel gears. By employing bevel gear meshing, the two second screws rotate synchronously when the transmission bevel gear rotates.

[0011] As an optimization, the contact cover plate is connected to an intermediate seat, the intermediate seat bearing is connected to the central shaft of the driving bevel gear, the driving bevel gear meshes with the transmission bevel gear, and the central shaft of the driving bevel gear is connected to a second handle. By using a second handle, it is convenient to rotate the driving bevel gear, thereby facilitating the rotation of the transmission bevel gear.

[0012] As an optimization, the arc-shaped clamp is connected to a set of evenly distributed arc-shaped protrusions.

[0013] As an optimization, the surface material of the blocking plate is rubber.

[0014] As an optimization, the first screw is connected to the first handle, which facilitates the rotation of the first screw.

[0015] The effects provided in the utility model description are merely those of the embodiments, and not all the effects of the utility model. The above technical solution has the following advantages or beneficial effects:

[0016] (1) This device uses a plug plate. When the plug plate enters the pipeline, the rubber on its surface undergoes elastic deformation, thereby sealing the pipeline.

[0017] (2) This device uses an arc-shaped clamp rod to clamp the pipe, so that the device is firmly fixed to the pipe.

[0027] like Figures 1 to 5 As shown in Embodiment 1: A temporary pipe end sealing device for gas pipeline construction includes: a contact cover plate 19 connected to a threaded cylinder 17; a first screw 2 threadedly connected to the threaded cylinder 17; a plug plate 12 connected to an mounting ring 21, with the first screw 2 bearing-connected to the mounting ring 21; and symmetrical guide rods 3, each connected to the plug plate 12 and passing through guide tubes 16, which are respectively connected to the contact cover plate 19. By using the plug plate 12, the contact cover plate 19 contacts the end of the pipeline, and the plug plate 12 enters the pipeline. Its surface rubber undergoes elastic deformation, thus sealing the pipeline.

[0028] The surface material of the blocking plate 12 is rubber.

[0029] The first screw 2 is connected to the first handle 1, which facilitates the rotation of the first screw 2.

[0030] The first screw 2 has a self-locking function.

[0031] The workflow of this embodiment is as follows:

[0032] Initially, the plug plate 12 is pressed against the contact cover plate 19. The plug plate 12 is then inserted into the pipe, causing the contact cover plate 19 to contact the end of the pipe. The first handle 1 is rotated, causing the first screw 2 to rotate. Simultaneously, the first screw 2 moves, causing the mounting ring 21 to move. The mounting ring 21 then moves the plug plate 12, which in turn moves the guide rod 3 along the guide tube 16, bringing the first handle 1 into close contact with the threaded cylinder 17, thus sealing the pipe.

[0033] Example 2: This example further elaborates on Example 1. The contact cover plate 19 is provided with symmetrical convex grooves 18, and protrusions 9 are respectively provided in the symmetrical convex grooves 18. The symmetrical protrusions 9 are respectively connected to arc-shaped clamping rods 10. By using arc-shaped clamping rods 10, the device can be installed on the pipeline when the arc-shaped clamping rods 10 clamp the pipeline.

[0034] The contact cover plate 19 is connected to a fixed seat 5 for each of the convex grooves 18, and the symmetrical protrusions 9 are connected to mounting seats 8. The symmetrical fixed seats 5 are respectively bearing the central axis of the second screw 7, and the symmetrical second screw 7 is respectively threaded to the corresponding mounting seat 8. By using the second screw 7, the movement of the arc-shaped clamp 10 is realized when it rotates.

[0035] The contact cover plate 19 is connected to the large ring 15, and the large ring 15 is connected to the transmission bevel gear 6 via a bearing. The symmetrical second screws 7 are respectively connected to the driven bevel gears 4, and the symmetrical driven bevel gears 4 respectively mesh with the transmission bevel gears 6. By using bevel gear meshing, the two second screws 7 rotate synchronously when the transmission bevel gear 6 rotates.

[0036] The second screw 7 has a self-locking function.

[0037] The contact cover plate 19 is connected to the intermediate seat 20, and the intermediate seat 20 is bearing-connected to the central shaft of the drive bevel gear 13. The drive bevel gear 13 meshes with the transmission bevel gear 6, and the central shaft of the drive bevel gear 13 is connected to the second handle 14. By using the second handle 14, it is convenient to rotate the drive bevel gear 13, thereby rotating the transmission bevel gear 6.

[0038] The arc-shaped clamp 10 is connected to a set of evenly distributed arc-shaped protrusions 11.

[0039] The workflow of this embodiment is as follows:

[0040] Rotating the second handle 14 causes the active bevel gear 13 to rotate, which in turn drives the transmission bevel gear 6 to rotate. The transmission bevel gear 6 drives the driven bevel gear 4 and the second screw 7 to rotate. The second screw 7 drives the mounting base 8 to move. The mounting base 8 drives the protrusion 9 to move along the convex groove 18. The protrusion 9 drives the arc-shaped clamping rod 10 and the arc-shaped protrusion 11 to move, so that the arc-shaped clamping rod 10 clamps the pipe, thus fixing the device to the pipe.

[0041] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
