Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-5 As shown, the present invention proposes an emergency repair and sealing device for gas transmission pipelines, comprising an upper sleeve 1, a lower sleeve 2, a threaded bracket 8, a screw 9, and a pressure plate 12. An installation port 4 is provided between the upper sleeve 1 and the lower sleeve 2. A sealing gasket 5 is provided at one opposite end of the upper sleeve 1 and the lower sleeve 2. Mounting plates 6 are provided at both ends of the upper sleeve 1 and the lower sleeve 2. Bolts 7 are provided between the mounting plates 6. A threaded bracket 8 is provided at one opposite end of the upper sleeve 1 and the lower sleeve 2. A sliding sleeve 14 is embedded inside the upper sleeve 1 and the lower sleeve 2. A travel rod 11 is slidably inserted inside the sliding sleeve 14. A screw 9, threadedly installed with the threaded bracket 8, is provided at the upper end of the travel rod 11. A pressure plate 12 is provided below the travel rod 11, and a pressure pad 17 is provided at the lower end of the pressure plate 12.

[0023] The upper sleeve 1 is provided with a hinge 3 at one end, and the hinge 3 is connected to the lower sleeve 2 at one end.

[0024] The upper end of the pressure plate 12 is provided with a bearing seat 19, and the lower end of the stroke rod 11 is rotatably inserted into the bearing seat 19;

[0025] The upper end of the pressure plate 12 has a positioning hole 16 inside, and the upper sleeve 1 and the lower sleeve 2 are each provided with a positioning rod 15 that slides into the positioning hole 16 at opposite ends.

[0026] The outer wall of the screw 9 is provided with rotating rods 13 arranged in a ring array;

[0027] Based on the implementation steps of Example 1: The upper clamping sleeve 1 and the lower clamping sleeve 2 are rotated open and fitted onto the outside of the damaged pipe. The bolt 7 is installed inside the mounting plate 6 to fix the upper clamping sleeve 1 and the lower clamping sleeve 2. During fixing, the sealing gasket 5 is squeezed and fits against the outer wall of the gas pipe, so that the upper clamping sleeve 1 and the lower clamping sleeve 2 are tightly fitted to the gas pipe. The leaked gas will be collected in the internal space of the upper clamping sleeve 1 and the lower clamping sleeve 2, and the leaked gas is intercepted. When installing the upper clamping sleeve 1 and the lower clamping sleeve 2, the pressure plate 12 corresponds to the broken part of the pipe. At the same time, the gripping rod 13 drives the screw 9 to rotate. The longitudinal force of the stroke rod 11 acts on the pressure plate 12. The pressure plate 12 drives the pressure pad 17 to press against the broken part of the pipe, and the broken part of the pipe is directly sealed. There are two seals, and no complicated tools are required. The pressure pad 17 is a flexible material that flexibly fits the broken part of the pipe and adapts to irregular cracks. The modular design allows for zero-time interception of leaked gas, saving valuable response time for professional maintenance teams.

[0028] like Figures 1-5 As shown, compared with Embodiment 1, the emergency repair and sealing device for gas transmission pipeline proposed in this utility model further includes: an installation column 18 is provided at the upper end of the screw 9, and a groove 26 distributed in a ring array is sleeved on the outer wall of the installation column 18, and a locking block 25 is provided inside the groove 26;

[0029] The upper sleeve 1 and the lower sleeve 2 are each provided with a support plate 10 at opposite ends. The card block 25 is provided with a stroke block 22 at one end, and a spring 23 is provided at one end of the stroke block 22. One end of the spring 23 is connected to the support plate 10.

[0030] A sliding sleeve 24 is embedded inside the support plate 10. One end of the stroke block 22 is provided with a push rod 21 located inside the spring 23 and slidably inserted into the sliding sleeve 24. One end of the push rod 21 is provided with a pull handle 20.

[0031] In this embodiment, when the screw 9 rotates, the gripping handle 20 drives the push rod 21 to move, and the push rod 21 drives the stroke block 22 and the locking block 25 to move, causing the locking block 25 to fall out of the slot 26. The spring 23 applies pressure to the stroke block 22. After the screw 9 rotates, the relaxed push rod 21 drives the locking block 25 to insert into the slot 26, limiting the mounting post 18 and preventing the screw 9 from rotating in the opposite direction. This makes the pressure plate 12 stable, and the leaked pressure acts on the pressure plate 12, preventing the pressure plate 12 from loosening. This improves the stability of the pressure plate 12 during temporary protection.

[0032] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
