Description

Technical Field

[0001] The utility model belongs to the technical field of gas engineering, and in particular relates to a temporary pipeline blocking mechanism for gas engineering construction. Background Art

[0002] Gas engineering refers not only to natural gas engineering, but also includes liquefied petroleum gas, coal-to-gas and heavy oil cracking gas. We use more natural gas now, so the gas engineering generally referred to now is also natural gas engineering. The scope of gas engineering is relatively broad, including large infrastructure projects such as gate stations, compressed gas stations and storage tanks, etc. General civil engineering includes community gas pipeline networks, urban gas pipeline networks, gas pressure regulating stations and in-building gas pipeline installation.

[0003] The existing Chinese patent document with the publication number CN220816974U discloses a sealing device for gas pipeline installation, including a sealing mechanism and an outer sealing ring installed inside the sealing mechanism, one side of the sealing mechanism is provided with an opening and closing air-sealing mechanism, and one side of the opening and closing air-sealing mechanism is provided with an opening and closing motor, the sealing mechanism includes a sealing mounting sleeve, the outer sealing ring is fixedly installed on one side of the inner part of the sealing mounting sleeve, wherein the end of the sealing mounting sleeve is symmetrically threaded with a clamping rotating rod on both sides, and the end of the clamping rotating rod is fixedly connected with a clamping knob, wherein the end of the clamping rotating rod away from the clamping knob is rotatably connected with a rotating bearing, and one side of the rotating bearing is rotatably connected with a clamping arm, by setting the sealing mechanism, not only the pipeline opening can be sealed when the gas pipeline is installed to avoid gas leakage, but also the clamping arm is used to clamp and fix the gas pipeline, thereby improving the sealing stability of the entire sealing mechanism.

[0004] Although the device has many beneficial effects, the following problems still exist: the movable slider, the sealing plug and the sealing installation sleeve in the above device are fixedly connected to the surface of the ventilation pipe, so that they cannot be disassembled and replaced. When a part is damaged, it can only be replaced as a whole, which is relatively wasteful. At the same time, when the gas pipeline is larger than the diameter of the movable slider, the sealing work cannot be completed, and the scope of application is small. Utility Model Content

By setting the first fixing rod 7, the second fixing rod 9, the first sleeve 2, the second sleeve 14, the movable rod 8 and the connecting rod 5, in actual applications, through the cooperation between the above, the size can be adjusted according to the different inner diameters of the gas pipeline, so that the device is suitable for the plugging work of gas pipelines with different diameters, and when the diameter of the gas pipeline exceeds the diameter of the limit ring 13, the plugging work of gas pipelines with different diameters can be met by replacing parts of different specifications, thereby improving the scope of application of the device. At the same time, when a single component is damaged, it can be replaced separately without replacing the entire component, saving material costs;

[0022] The adjusting mechanism 4 comprises an extension plate 402, a through hole 403 is provided inside the extension plate 402, a first threaded tube 401 is fixedly connected to the surface of the extension plate 402, a first threaded column 404 is threadedly connected to the inside of the first threaded tube 401, an adjusting knob 405 is fixedly connected to one end of the first threaded column 404, a second threaded column 406 is fixedly connected to the surface of the adjusting knob 405, a second threaded tube 407 is threadedly connected to the surface of the second threaded column 406, and the adjusting mechanism 4 and the bolt fastener 12 are arranged, and in actual applications, through the cooperation between the above, not only the stability of each component of the device is ensured, but also the close contact strength between the device and the inner and outer surfaces of the gas pipeline is increased, thereby preventing the device from being ejected due to the gas pressure and ensuring the sealing effect on the gas pipeline.

[0023] Specifically, there are four first fixing rods 7, two second fixing rods 9, two third fixing rods 10, and six telescopic plates 6. The surfaces of the four first fixing rods 7 are fixedly connected with connecting rods 5 and are connected in pairs through connecting rods 5. The third fixing rod 10 and one side of the first fixing rod 7 are fixedly connected to the telescopic plates 6 at different positions.

[0024] Specifically, the extension plate 402 is sleeved with the pin shaft 16 through the through hole 403 , and the thread directions of the first threaded column 404 and the second threaded column 406 are opposite.

[0025] Specifically, a groove 15 is provided inside the adapter block 3 , and the pin shaft 16 and one side of the extension plate 402 are both distributed inside the pin shaft 16 .

[0026] The working principle of the utility model is:

[0027] S1. When the device is used, first insert one end of the ventilation pipe 1 together with the airbag 11 into the interior of the gas pipe, then inflate the airbag 11 through the ventilation pipe 1 to make it expand to fit tightly against the inner surface of the gas pipe, and then seal the ventilation pipe 1, and then rotate and adjust the rotation to drive the first threaded column 404 and the second threaded column 406 to rotate inside the first threaded tube 401 and the second threaded tube 407. Since the thread directions of the first threaded column 404 and the second threaded column 406 are opposite, the synchronous rotation of the first threaded column 404 and the second threaded column 406 will push the second threaded tube 407 and the first threaded tube 401 to move away from or closer to each other, thereby pushing the second fixed rod 9 to move under the cooperation of the adapter block 3 and the pin shaft 16, and the movable rod 8 then telescopes inside the first fixing rod 7 and the second fixing rod 9, and the telescopic plate 6 then telescopes until the first fixing rod 7 and the second fixing rod 9 are in close contact with the inner surface of the gas pipeline, then the rotation of the adjusting knob 405 can be stopped, and under the action of the connecting rod 5, the third fixing rod 10 moves along with the movement of the second fixing rod 9 until it and the second fixing rod 9 are in close contact with the inner surface of the gas pipeline at the same time, thereby increasing the friction force and ensuring the fastening effect of the device, and then adjusting the position of the limiting ring 13 on the ventilation pipeline 1 through the second ring until the inner surface of the limiting ring 13 is in close contact with the open end of the gas pipeline, then the bolt fastener 12 can be rotated to make one end of it close contact with the outer surface of the gas pipeline, further increasing the fastening effect of the device, thereby preventing the device from being ejected due to the gas pressure;

[0028] S2. When a component of the device is damaged or a component is to be replaced for a gas pipeline of different diameter, the bolt fastener 12 needs to be rotated so that the bolt fastener 12 is separated from the ventilation pipeline 1, and the first sleeve 2 and the second sleeve 14 can be removed to replace each damaged component or to replace the corresponding components according to the different diameters of the gas pipeline.
