Description

Technical Field

[0001] The utility model relates to the field of pipeline fixing, in particular to a pipeline fixing device which is easy to adjust. Background Art

[0002] Pipelines are divided into oil pipes, water pipes and gas pipes. Oil pipes and water pipes are mainly used to transport liquids such as oil and water, while gas pipes are mainly used to transport gases such as gas or flue gas. In the prior art, the length of the pipeline is limited. When the pipeline needs to be extended, two adjacent pipelines need to be spliced ​​and fixed with flanges.

[0003] However, when the pipeline is installed, the pipeline joints are relatively fragile. When some gas pipelines are connected and installed, they are only connected by flanges, and lack adjustable protective devices. When heavy objects collide with them, it is easy to cause cracks in the pipeline joints, causing gas or liquid leakage. Once the gas or liquid leaks, it will not only pollute the surrounding environment, but also easily cause safety hazards to surrounding personnel.

[0004] Therefore, it is necessary to invent a pipeline fixing device that is easy to adjust. Utility Model Content

[0008] Based on the above characteristics: when two pipes are connected, they can be connected and fixed by a flange. When the pipe needs to be fixed, the protective assembly composed of the first protective cover and the second protective cover can be put on the outside of the connection between the two pipes. At this time, the flange will be located on the inside of the protective assembly, and the sealing assemblies on both sides of the first protective cover and the second protective cover are tightly wrapped around the outside of the two pipes. If the protective assembly needs to be fixed on the ground, the fixed base can be inserted into the inner side of the connecting base plate, and the connection between the two can be fixed with bolts, and then the fixed base can be fixed to the ground with bolts. At this time, the connecting base plate and the fixed base can support the lower end of the pipe and the protective assembly.

When the locking screw stops rotating, the fixing nut can lock and fix the locking screw.

[0013] Preferably, the limiting plate is arranged in a semi-arc structure.

[0014] Based on the above characteristics: the semi-arc structure of the limit plate matches the radius of the pipe, and the limit plate cooperates with the buffer spring to elastically support the lower end of the pipe, so that the pipe remains stable inside the protective component.

[0031] The protection assembly 2 includes a first protection sleeve 21 and a second protection sleeve 22. The first protection sleeve 21 is located at the lower end of the pipeline 1, and the second protection sleeve 22 is located at the upper end of the pipeline 1. Connecting lugs 23 are fixedly installed on both sides of the first protection sleeve 21, the second protection sleeve 22 and the sealing assembly 3.

[0032] When two pipes 1 are connected, they can be connected and fixed by a flange. When the pipe 1 needs to be fixed, the protective assembly 2 composed of the first protective sleeve 21 and the second protective sleeve 22 can be installed on the outside of the connection between the two pipes 1. At this time, the flange will be located on the inner side of the protective assembly 2, and the sealing assemblies 3 on both sides of the first protective sleeve 21 and the second protective sleeve 22 will be tightly wrapped around the outside of the two pipes 1. If the protective assembly 2 needs to be fixed on the ground, the fixed base 5 can be inserted into the inner side of the connecting base plate 4, and the connection between the two can be fixed with bolts, and then the fixed base 5 can be fixed to the ground with bolts. At this time, the connecting base plate 4 and the fixed base 5 can support the lower ends of the pipe 1 and the protective assembly 2. The first protective sleeve 21 and the second protective sleeve 22 are semi-arc structures. When the two are assembled oppositely, a circular tubular structure will be formed. Subsequently, the connecting lugs 23 on both sides of the first protective sleeve 21 and the second protective sleeve 22 are connected and fixed with bolts to prevent the first protective sleeve 21 and the second protective sleeve 22 from separating.

[0033] Furthermore, a card slot 211 is symmetrically opened on the end face of the first protective sleeve 21, and a receiving cavity 212 is opened in the inner cavity of the first protective sleeve 21 and the second protective sleeve 22. A buffer spring 213 is fixedly installed on the inner wall of the first protective sleeve 21, and a limiting plate 214 is installed at one end of the buffer spring 213 away from the first protective sleeve 21.

[0034] When the first protective sleeve 21 and the second protective sleeve 22 are mounted on the outside of the pipeline 1, the flange at the connection between the two pipelines 1 will be located on the inner side of the accommodating cavity 212. At the same time, since there are two limit plates 214, the two limit plates 214 will support the lower end of the pipeline 1 on both sides of the flange. The limit plates 214 can be adaptively telescopically adjusted through the buffer springs 213, so that the limit plates 214 can fit closely to the outside of the lower end of the pipeline 1.

[0035] Furthermore, a fixing nut 221 is installed at one end of the second protective sleeve 22 away from the first protective sleeve 21, a locking screw 222 is threadedly connected in the middle of the fixing nut 221, a detector 223 is installed on one side of the second protective sleeve 22, and a clamping block 224 is fixedly installed on the end face of the second protective sleeve 22.

When the locking screw 222 stops rotating, the fixing nut 221 can lock and fix the locking screw 222. When the first protective sleeve 21 and the second protective sleeve 22 are assembled, the second protective sleeve 22 will fit above the first protective sleeve 21. At this time, the block 224 at the lower end of the second protective sleeve 22 will also be inserted into the slot 211 above the first protective sleeve 21, so as to avoid the first protective sleeve 21 and the second protective sleeve 22 from being pressed against each other. After assembly, a gap is left at the connection, and the detector 223 is electrically connected to the alarm. The detector 223 can be a gas detector or a liquid level sensor. If the gas transported in the pipeline 1 leaks, the leaked gas will flow into the protective component 2. When the gas detector detects that there is gas inside the protective component 2, an alarm can be sounded to alert the surrounding personnel. If the liquid transported in the pipeline 1 leaks, the leaked liquid will flow into the protective component 2. When the liquid level sensor detects that there is liquid inside the protective component 2, an alarm can be sounded to alert the surrounding personnel. The specific installation can be based on whether the pipeline 1 is transporting gas or liquid.

[0037] Furthermore, the limiting plate 214 is arranged in a semi-arc structure.

[0038] The semi-arc-shaped limit plate 214 matches the radius of the pipe 1 , and the limit plate 214 cooperates with the buffer spring 213 to elastically support the lower end of the pipe 1 , so that the pipe 1 remains stable inside the protective component 2 .

[0040] The fixed sleeve 31 is composed of two semi-arc sleeves, which form a circular structure after splicing. The inner diameter of the fixed sleeve 31 is the same as the outer diameter of the pipeline 1, which is convenient for the fixed sleeve 31 to be connected and fixed to the outside of the pipeline 1. When the fixed sleeve 31 is connected to the pipeline 1, the annular airbag 33 can be inflated to expand it. Then, one side of the inflated annular airbag 33 will be tightly attached to the outside of the pipeline 1, and the other side will be limited in the annular groove 32, which is convenient for sealing between the fixed sleeve 31 and the pipeline 1, and tries to prevent leaked gas or liquid from overflowing through the gap between the fixed sleeve 31 and the pipeline 1.

[0041] Furthermore, an air nozzle 331 is installed at one end of the annular airbag 33 , and a sealing plug 332 is threadedly connected to the other end of the air nozzle 331 .

[0042] When it is necessary to inflate the annular airbag 33 , the sealing plug 332 can be opened and the air nozzle 331 can be used to inflate the annular airbag 33 . After the inflation is completed, the sealing plug 332 can be tightened to prevent the annular airbag 33 from leaking.

[0045] The use process of the utility model is as follows: when two pipes 1 are connected, they can be connected and fixed by a flange. When the pipe 1 needs to be fixed, the protective assembly 2 composed of the first protective sleeve 21 and the second protective sleeve 22 can be put on the outside of the connection between the two pipes 1. When the first protective sleeve 21 and the second protective sleeve 22 are assembled, the second protective sleeve 22 will fit on top of the first protective sleeve 21. At this time, the clamping block 224 at the lower end of the second protective sleeve 22 will also be clamped into the clamping groove 211 above the first protective sleeve 21. Then, the connecting lugs 23 on both sides of the first protective sleeve 21 and the second protective sleeve 22 are connected and fixed by bolts, and the fixed sleeve 31 is connected and fixed to the outside of the pipe 1. When the fixed sleeve 31 and the pipe After pipeline 1 is connected, air can be inflated into the annular airbag 33 to expand it, and then the inflated annular airbag 33 will seal between the fixed sleeve 31 and the pipeline 1. The detector 223 is electrically connected to the alarm. The detector 223 can be a gas detector or a liquid level sensor. If the gas transported in pipeline 1 leaks, the leaked gas will flow into the protection component 2. When the gas detector detects that there is gas in the protection component 2, an alarm can be sounded to alert the surrounding personnel. If the liquid transported in pipeline 1 leaks, the leaked liquid will flow into the protection component 2. When the liquid level sensor detects that there is liquid in the protection component 2, an alarm can be sounded to alert the surrounding personnel.
