Description

Technical Field

[0001] The invention relates to the technical field of anti-slip strips for thermal pipelines, and in particular to a segmented anti-slip strip for thermal pipelines. Background Art

[0002] With the acceleration of urbanization and the improvement of people's living standards, the central heating system plays an increasingly important role in urban heating. The central heating system transmits the heat energy produced by the heat source plant to the user end through the heat pipe to meet the heating needs of residents and industries. In this heating system, the safe and stable operation of the heat pipe is crucial.

[0003] Thermal pipelines are usually laid underground. Affected by geological conditions, temperature changes, external forces and other factors, pipelines are prone to slippage and deformation, especially in long-distance pipelines or under complex geological conditions. To solve this problem, various forms of fixed supports and sliding supports have been traditionally used, but these supports often fail to take into account both the free expansion and contraction and anti-slip stability of the pipeline, and there are certain technical bottlenecks.

[0004] Existing anti-slip technologies for thermal pipelines mainly rely on supports and anchoring structures. These technologies can play a role in fixing and anti-slip to a certain extent, but they also have some shortcomings. For example, in a large temperature difference environment, the displacement caused by the thermal expansion and contraction of the pipeline is large, and the traditional fixed supports are easily damaged. The sliding supports cause the pipeline to slip due to insufficient friction, making it difficult to ensure the safety of the pipeline. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a segmented thermal pipeline anti-slip strip to solve the problem that when the thrust of the thermal pipeline structure is too large, the friction force cannot be resisted and the structure will be cracked, which poses a huge threat to the safety of the structure.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A segmented thermal pipeline anti-slip strip includes a pipe body, which is the main part of the thermal pipeline and is used to transport heat medium;

[0007] Anti-slip components are installed on the outer periphery of the pipe body to increase the contact area between the pipe body and the soil to reduce the displacement of the pipe body during thermal expansion;

[0008] Hoop 2, installed on the outside of the anti-slip assembly, used to connect multiple anti-slip assemblies;

[0009] The clamping assembly is used to splice the hoop part 2 and the anti-slip assembly.

[0010] Preferably, the anti-slip assembly includes two hoop members, one end of the two hoop members are connected by a hinge, the other end of the hoop members is fixedly connected to a mounting member, and the two mounting members are connected by a high-strength bolt.

[0011] Preferably, a recess is provided in a middle portion of the hoop, and a plurality of pressure-bearing baffles are installed outside the recess to further increase the contact area with the soil.

[0012] Preferably, the clamping assembly includes a guide groove, which is opened on the outside of the second hoop member, one end of the guide groove is an entrance section, and the other end of the guide groove is a clamping section. A convex nail is fixedly connected to the outside of the first hoop member, and the convex nail and the guide groove are clamped.

[0013] Preferably, the clamping assembly also includes a clamping block, which is slidably connected to the outer side of the second hoop member, a spring is fixedly connected inside the second hoop member, the other end of the spring is fixedly connected to the inner side of the clamping block, and a clamping groove is provided on the outer side of the first hoop member, and the clamping groove and the clamping block are clamped to each other.

[0014] Preferably, the inner sides of the first hoop and the second hoop are fixedly connected with anti-slip hoops for increasing the friction force at the contact position with the pipe body.

[0015] Preferably, a notch is provided on the outer edge of the hoop member 1 to increase the axial friction between the hoop member 1 and the soil.

[0016] Preferably, a second notch is formed on the outer side of the second hoop, and the second notch and the first notch are aligned with each other.

[0017] Preferably, a connecting piece is fixedly connected to the outer side of the first hoop member, and a connecting groove is provided on the inner side of the second hoop member, and the connecting piece and the connecting groove have matching sizes.

[0018] Working principle: When laying the thermal pipeline, a set of hoop is connected to the outside of the pipe body, and then hoop one is fastened by mounting parts and high-strength bolts. After the pipe body is buried as a whole, the soil will accumulate in the middle of the concave part, which can increase the friction between the pipe body and the soil, thereby reducing the displacement of the thermal pipeline to avoid the pipe body structure being inferred. If the current soil is relatively loose and the soil extrusion force is insufficient, hoop two can be connected to the outside of hoop one through a clamping assembly. The specific steps are to first stagger the hoop two with the hoop one, so that the convex nail enters the inside of the guide groove from the entrance section, and then moves along the The hoop piece 2 is rotated in the direction of the guide groove. When the convex nail reaches the position of the clamping section, the spring pushes the clamping block out and makes the clamping block and the clamping groove complete the clamping connection. At this time, the hoop piece 1 and the hoop piece 2 can be aligned. Then the assembled parts are sleeved on the outside of the pipe body and connected again through the mounting parts and high-strength bolts to complete the installation of the anti-slip strip. This can further increase the contact area with the soil and ensure the squeezing force on the pipe body. At the same time, the outside of the hoop piece 2 can also be connected with a new hoop piece 1 in the same way. In this cycle, the length of the entire anti-slip structure can be adjusted according to the fluffiness of the soil to adapt to different environmental needs.

[0019] The present invention provides a segmented thermal pipeline anti-slip strip, which has the following beneficial effects:

[0020] 1. The present invention increases the contact area with the soil through the hoop member 1 and the external recess and pressure baffle, thereby reducing the displacement of the pipe body caused by thermal action to avoid the pipe body being pushed. The hoop member 1 is connected by a mounting member and a high-strength bolt to ensure the strength after installation and improve the installation efficiency.

[0021] 2. In the present invention, a plurality of hoop members 1 can be combined through hoop members 2 and a clamping assembly, and the number can be freely increased according to the fluffiness of the soil in the current environment to meet the installation needs in different environments.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Example:

[0031] Please see attached Figure 1 -Attached Figure 3 The embodiment of the present invention provides a segmented anti-slip strip for a thermal pipeline, including a pipe body 1, which is the main part of the thermal pipeline and is used to transport heat medium; after the pipe body 1 is buried, the pipe body 1 will be in full contact with the soil.

[0032] The anti-slip assembly is installed on the outer periphery of the pipe body 1, and is used to increase the contact area between the pipe body 1 and the soil, so as to reduce the displacement of the pipe body 1 during thermal expansion; the anti-slip assembly includes two hoop members 2, one end of the two hoop members 2 is connected by a hinge, and the other end of the hoop members 2 is fixedly connected with a mounting member 8, and the two mounting members 8 are connected by a high-strength bolt 9. After the hoop member 2 is hooped on the outside of the pipe body 1, the two mounting members 8 at the other end of the hoop member 2 are aligned, and then the two mounting members 8 are locked by the high-strength bolt 9, and at this time, the hoop member 2 is also in full contact with the pipe body 1 under the action of friction. A recess 3 is provided in the middle of the hoop 2, and a plurality of pressure baffles 7 are installed outside the recess 3 to further increase the contact area with the soil. After the pipe body 1 is buried, the soil will accumulate in the area formed by the recess 3 and the pressure baffles 7. At this time, the contact area with the soil can be increased. When the pipe body 1 is displaced laterally, the side edge of the recess 3 squeezes the soil, thereby reducing the deformation and expansion of the pipe body 1. At the same time, a certain axial rotational force will inevitably be generated during the lateral displacement. At this time, the pressure baffles 7 will grab the surrounding soil, thereby reducing the axial rotation amount, thereby further improving the stability of the pipe body 1.

[0033] Hoop member 2 4 is installed on the outside of the anti-slip component and is used to connect multiple anti-slip components; the inside of hoop member 1 2 and hoop member 2 4 are fixedly connected with anti-slip hoops 19 to increase the friction force at the contact position with the pipe body 1.

[0034] Please see attached Figure 3 -Attached Figure 6 , a clamping assembly is used to splice the hoop 2 4 and the anti-slip assembly. A notch 5 is provided on the outer edge of the hoop 2 to increase the axial friction between the hoop 2 and the soil, and to grab the surrounding soil through the notch 5, thereby reducing the axial rotation. A notch 26 is provided on the outside of the hoop member 24, and the notch 26 and the notch 15 are aligned with each other. The notch 26 and the notch 15 have the same function, both of which increase the contact area with the soil while grabbing the surrounding soil, thereby reducing the axial rotation amount; the clamping assembly includes a guide groove 12, and the guide groove 12 is provided on the outside of the hoop member 24, one end of the guide groove 12 is an entrance section 13, and the other end of the guide groove 12 is a clamping section 14. A convex nail 15 is fixedly connected to the outside of the hoop member 2, and the convex nail 15 and the guide groove 12 are clamped. When the current soil is relatively fluffy and the soil extrusion force is insufficient, the convex nail 15 is inserted into the guide groove 12 from the entrance section 13, and then the hoop member 24 is rotated along the direction of the guide groove 12. When the convex nail 15 reaches the position of the clamping section 14, the hoop member 12 and the hoop member 24 can be aligned.

[0035] Please see attached Figure 4 and attached Figure 6 The clamping assembly also includes a clamping block 17, which is slidably connected to the outer side of the hoop member 24, and a spring 16 is fixedly connected inside the hoop member 24. The other end of the spring 16 is fixedly connected to the inner side of the clamping block 17. A clamping groove 18 is provided on the outer side of the hoop member 12, and the clamping groove 18 and the clamping block 17 are clamped with each other. After the hoop member 12 and the hoop member 24 are clamped and aligned, when the convex nail 15 reaches the position of the clamping section 14, the spring 16 pushes the clamping block 17 out and completes the clamping of the clamping block 17 with the clamping groove 18. In this way, the length of the entire anti-slip structure can be adjusted according to the fluffiness of the soil. At the same time, the outer side of the hoop member 24 can also be connected to a new hoop member 2 in the same way. In this way, the number can be freely increased according to the fluffiness of the soil in the current environment to meet the installation needs under different environments.

[0036] Please see attached Figure 2 -Attached Figure 3 A connecting piece 10 is fixedly connected to the outer side of hoop piece 1 2, and a connecting groove 11 is opened on the inner side of hoop piece 2 4. The connecting piece 10 and the connecting groove 11 are matched in size. When hoop piece 1 2 and hoop piece 2 4 are overlapped, the connecting piece 10 will fit with the connecting groove 11. At this time, the rotation of hoop piece 2 4 can be guided to improve the stability and convenience of assembly of hoop piece 1 2 and hoop piece 2 4.
