Description

Technical Field

[0001] The utility model relates to the technical field of gas pipeline plugging, and more specifically, to a temporary plugging device for a gas pipeline. Background Art

[0002] After the gas pipeline is cut, the old pipeline is generally left open in place before being demolished or landfilled, without any other treatment measures. After the gas pipeline is cut, the old pipeline is generally left open in place for several days before being demolished or landfilled. The old pipeline contains gas odor accumulated due to years of operation, which may cause pedestrians and residents to falsely report leaks after smelling it, resulting in a waste of manpower and material resources.

[0003] In the existing published technical literature, the patent with patent announcement number CN115451232A discloses an adaptive gas pipeline plugger, which is composed of a combination of arc-shaped parts distributed along the circumferential direction through an expansion ring, and shrinkage gaps are provided between adjacent arc-shaped parts. The arc-shaped parts of the smallest expansion ring in each expansion ring group are fixedly connected to the corresponding support plate through the first steel sheet, and the arc-shaped parts of adjacent expansion rings in each expansion ring group are fixedly connected one by one through the second steel sheet. It has the advantages of simple structure, easy operation, reliable plugging, and strong adaptability. However, the plugger has the following problems;

[0004] Although the plugger can be inserted into the gas pipeline for temporary plugging, it needs to be squeezed hard during the insertion process. The force exerted by people during squeezing is relatively large, so it is difficult to achieve impact-type plugging, and the plugging is more time-consuming and labor-intensive. Therefore, a temporary plugger for the gas pipeline is needed. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a temporary plugging device for a gas pipeline, comprising a screw, a pushing block and a push rod, wherein the pushing block is fixed at one end of the screw, the push rod is fixed at the upper surface of the pushing block, and the outer wall of the push rod is provided with a holding and impacting assembly; the holding and impacting assembly comprises a limiting ring fixedly arranged on the outer wall of the push rod, and a guide column is fixedly connected to one side of the pushing block, an impact ring is fixedly installed on the outer wall of the guide column, and two impact columns are provided on one side of the impact ring; an impact sleeve is installed on one side of the impact column, and the inner wall of the impact sleeve is slidably connected to the outer wall of the guide column.

[0007] Preferably, the pushing block and the impact ring are fixedly connected, and both the pushing block and the impact ring are made of stainless steel. The two impact columns are arranged at equal intervals in a circular arrangement. The two impact columns are fixedly connected to the impact sleeve. The inner wall of the impact sleeve is slidably connected to the outer wall of the guiding column, and both the inner wall of the impact sleeve and the outer wall of the guiding column are smooth surfaces.

[0008] Preferably, a supporting block is fixedly installed at one end of the guiding column, and the supporting block is used to limit the movement of the impact sleeve. A limiting support ring is installed above the limiting ring, and the limiting support ring is fixedly connected to the push rod; the cross-sections of both the limiting support ring and the limiting ring are circular rings.

[0009] In this technical solution, the hand can hold the outer wall of the push rod, and the limiting ring limits the lower surface of the hand. Then, the other hand holds the outer wall of the impact sleeve. The impact sleeve drives the two impact columns to move leftward and impact. The two impact columns move leftward and impact the impact ring. The pushing block drives the screw to move leftward and impact. At the same time, the screw drives the first nut of the limiting support ring to make the pushing ring move leftward and impact. The plugging sleeve drives the guiding sleeve to impact and move leftward along the inner wall of the gas pipeline. The impact sleeve can reciprocate to achieve impact movement. The first nut drives the pushing ring to make the plugging sleeve continuously impact leftward. The guiding sleeve and the plugging sleeve can continuously impact and seal along the inside of the gas pipeline.

[0010] Preferably, a limiting plugging assembly is provided on the outer wall of the screw; the limiting plugging assembly includes a plugging sleeve slidably arranged on the outer wall of the screw, and a guiding sleeve is fixedly connected to one side of the plugging sleeve.

The inner wall of the second nut is threadedly connected to the screw.

[0011] In this technical solution, when the screw impacts leftward, the first nut drives the pushing ring to move leftward and impact. The pushing block drives the pushing ring to move leftward and impact. At the same time, the plugging sleeve drives the guiding sleeve to make the limiting sleeve move leftward and impact. The limiting sleeve drives the second nut to move leftward. The plugging sleeve and the guiding sleeve can stably receive force to seal the gas pipeline.

The plugging sleeve drives the guide sleeve to impact and move leftward along the inner wall of the gas pipeline, and then moves rightward and then impacts the impact sleeve to the left to push the impact sleeve. The first nut drives the push ring to continuously impact the plugging sleeve to the left. The guide sleeve and the plugging sleeve can continuously impact and plug along the inside of the gas pipeline, making the temporary plugging of the gas pipeline more time-saving and labor-saving.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] As shown in the attached Figures 1-5 drawing, there is a temporary gas pipeline plugging device. A holding and impact assembly is provided on the temporary gas pipeline plugging device. The setting of the holding and impact assembly enables the first nut 16 to drive the push ring 15, so that the plugging sleeve 11 continuously impacts to the left. The guide sleeve 12 and the plugging sleeve 11 can continuously impact and plug along the inside of the gas pipeline, making it more time-saving and labor-saving to temporarily plug the gas pipeline. The specific structure of the holding and impact assembly is set as follows.

[0023] In this embodiment, as shown in the attached Figures 1-3 drawing, the push block 2 is fixed to one end of the screw rod 1, the push rod 3 is fixed to the upper surface of the push block 2, and a holding and impact assembly is provided on the outer wall of the push rod 3; the holding and impact assembly includes a limit ring 4 fixedly arranged on the outer wall of the push rod 3, and a guide post 5 is fixedly connected to one side of the push block 2. An impact ring 6 is fixedly installed on the outer wall of the guide post 5, and two impact posts 7 are provided on one side of the impact ring 6; an impact sleeve 8 is installed on one side of the impact post 7, and the inner wall of the impact sleeve 8 is slidably connected to the outer wall of the guide post 5. The push block 2 is fixedly connected to the impact ring 6, and both the push block 2 and the impact ring 6 are made of stainless steel. The two impact posts 7 are arranged in an equidistant circular arrangement, and both the two impact posts 7 are fixedly connected to the impact sleeve 8. The inner wall of the impact sleeve 8 is slidably connected to the outer wall of the guide post 5, and both the inner wall of the impact sleeve 8 and the outer wall of the guide post 5 are set as smooth surfaces.

[0024] In this embodiment, as shown in the attached Figure 3 drawing, a support block 9 is fixedly installed at one end of the guide post 5, and the support block 9 is used to limit the movement of the impact sleeve 8, so that the support block 9 can limit the impact sleeve 8, thus realizing a stable limiting operation on the impact sleeve 8. A limit support ring 10 is installed above the limit ring 4, and the limit support ring 10 is fixedly connected to the push rod 3; the cross-sections of both the limit support ring 10 and the limit ring 4 are circular rings, so that the hand can be held on the outer wall of the push rod 3, and the upper surface of the hand is limited by the limit support ring 10 to prevent the hand from slipping on the limit support ring 10, and the anti-slip effect is better.

[0025] When this technology is used for temporary plugging of gas pipelines, one hand can hold the outer wall of the push rod 3, and the upper surface of the hand is limited by the limit support ring 10. At the same time, the limit ring 4 limits the lower surface of the hand. Then, the other hand holds the outer wall of the impact sleeve 8 and pushes it to the left through the impact sleeve 8. The impact sleeve 8 drives the two impact columns 7 to move to the left and impact. At the same time, the impact sleeve 8 moves to the left along the outer wall of the guide post 5, and the two impact columns 7 move to the left and impact the impact ring 6. The impact ring 6 drives the push block 2 to move to the left and impact, and the push block 2 drives the screw rod 1 to move to the left and impact.

[0026] At the same time, the screw rod 1 drives the first nut 16 of the limit support ring 10 to make the push ring 15 move to the left and impact. The push ring 15 pushes the plugging sleeve 11 to impact. The plugging sleeve 11 drives the guide sleeve 12 to impact and move to the left along the inner wall of the gas pipeline. Then, after moving the impact sleeve 8 to the right and then to the left to impact and push the impact sleeve 8, the impact sleeve 8 can reciprocally move and impact, so that the screw rod 1 drives the first nut 16 to continuously impact to the left. The first nut 16 drives the push ring 15 to make the plugging sleeve 11 continuously impact to the left. The plugging sleeve 11 carries the guide sleeve 12 to continuously impact to the left. The guide sleeve 12 and the plugging sleeve 11 can continuously impact and plug along the inside of the gas pipeline.

[0027] In this embodiment, as shown in the appendix Figures 1-5 As shown, a limit plugging assembly is provided on the outer wall of the screw rod 1; the limit plugging assembly includes a plugging sleeve 11 slidably arranged on the outer wall of the screw rod 1, and one side of the plugging sleeve 11 is fixedly connected with a guide sleeve 12. The inner wall of the guide sleeve 12 is slidably connected with the outer wall of the screw rod 1. On the other side of the plugging sleeve 11, a push ring 13 is installed;

[0028] The inner wall of the push ring 13 is fixedly connected with a plurality of push blocks 14, and one end of the push block 14 is provided with a push ring 15. A plurality of push blocks 14 are fixedly connected with the push ring 15. One side of the push ring 15 is rotatably connected with a first nut 16, and the first nut 16 is threadedly connected with the screw rod 1; one side of the guide sleeve 12 is rotatably installed with a limit sleeve 17, and one side of the limit sleeve 17 is fixedly connected with a second nut 18. The inner wall of the second nut 18 is threadedly connected with the screw rod 1.

[0029] When this technology is in use, when the screw rod 1 impacts to the left, the screw rod 1 will drive the first nut 16 to move to the left, and the first nut 16 drives the push ring 15 to move to the left and impact. The push ring 15 makes a plurality of push blocks 14 move to the left and impact. The push blocks 14 drive the push ring 13 to move to the left and impact, and the push ring 13 squeezes the plugging sleeve 11 to move to the left and impact. At the same time, the plugging sleeve 11 drives the guide sleeve 12 to make the limit sleeve 17 move to the left and impact. The limit sleeve 17 carries the second nut 18 to move to the left. In this way, the plugging sleeve 11 and the guide sleeve 12 can stably move and plug inside the gas pipeline. The plugging sleeve 11 and the guide sleeve 12 can be stably stressed to plug the gas pipeline, and can temporarily plug the open old pipeline.

[0030] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
