Description

Technical Field

[0001] The utility model relates to the field of pipeline coating tapes, and particularly relates to a coating tape for directional drilling pipeline crossing. Background Art

[0002] The directional drilling crossing technology has the characteristics of short construction period and small environmental disturbance, and is suitable for the laying of buried pipelines in areas such as railways, highways, and rivers. It is an efficient trenchless buried pipeline laying technology and has been widely used in the construction of oil and gas and municipal pipelines.

[0003] Traditional coating tapes usually use special materials to make the protective layer. These materials perform well in anti-corrosion and impact resistance, effectively extending the service life of the pipeline. However, when facing hard strata such as rocks and sandy soils during pipeline crossing, the performance of traditional coating tapes in abrasion resistance and scratch resistance is insufficient. During the directional drilling crossing process, the coating tape comes into frequent contact with media such as soil and rock, generating extremely large frictional forces. This high-intensity friction will cause the coating tape to wear more severely, and even directly damage the protective layer. Once the protective layer is damaged, the exposed pipeline loses an effective protection barrier and is extremely vulnerable to damage from corrosive substances and sharp stones in the soil, thus affecting the overall performance and safety of the pipeline. Content of the Utility Model

[0004] The utility model aims at the deficiencies of the existing technology and provides the following technical solution: a coating tape for directional drilling pipeline crossing, including a pipeline, a protective layer is arranged on the periphery of the pipeline, a rotating layer is movably arranged on the periphery of the protective layer, a limiting groove is opened on the outer peripheral surface of the pipeline, a limiting block is fixedly installed in the limiting groove, the limiting block is fixedly connected to the inner side of the protective layer, a rotating groove is opened on the outer peripheral surface of the protective layer, a rotating ring is movably installed in the rotating groove, the outer periphery of the rotating ring is fixedly connected to the inner side of the rotating layer, an installation groove is opened in the rotating groove and at the lower end of the rotating ring, and a rolling ball is movably arranged in the installation groove.

[0005] As an improvement of the above technical solution, a plurality of guiding strips are arranged on the outer periphery of the rotating layer, and the guiding strips are spirally wound around the outer periphery of the rotating layer.

[0006] As an improvement of the above technical solution, the limiting groove opened on the outer periphery of the pipeline and the rotating groove opened on the outer periphery of the protective layer are arranged staggeredly.

[0007] As an improvement of the above technical solution, there are a plurality of installation grooves formed by the rotating groove and the rotating ring, and the installation groove opened at the lower end of the rotating ring has a larger space than the installation groove opened in the rotating groove.

[0008] As an improvement of the above technical solution, the cross section of the rotating ring is T-shaped.

[0009] Advantages of the present utility model: Through the combination of the protective layer and the rotating layer, the protective performance of the pipeline is enhanced. The protective layer closely adheres to the pipeline. By virtue of the stable connection between the limiting block and the limiting groove, it can effectively resist the erosion and impact of the external environment. The introduction of the rotating layer, with the ingenious design of the rotating ring and the rolling balls, endows the coating belt with high flexibility in complex terrains. It can automatically adjust its posture during the crossing process, disperse the impact and reduce the soil layer friction, thereby ensuring the stability and smoothness of the pipeline crossing, extending the service life of the pipeline, reducing the crossing difficulty and maintenance cost, and providing an efficient and reliable solution for the directional drilling crossing project.

[0015] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0016] Please refer to Figures 1-4 , the present utility model provides a technical solution: A directional drilling crossing pipeline coating belt, including a pipeline 10, a protective layer 11 is arranged on the periphery of the pipeline 10, a rotating layer 12 is movably arranged on the periphery of the protective layer 11, a limiting groove 20 is opened on the peripheral surface of the pipeline 10, a limiting block 21 is fixedly installed inside the limiting groove 20, the limiting block 21 is fixedly connected to the inner side of the protective layer 11, a rotating groove 22 is opened on the peripheral surface of the protective layer 11, a rotating ring 23 is movably installed inside the rotating groove 22, the rotating ring 23 is fixedly connected to the inner side of the rotating layer 12, a mounting groove 24 is opened inside the rotating groove 22 and at the lower end of the rotating ring 23, and a rolling ball 25 is movably arranged inside the mounting groove 24.

[0017] In this embodiment, by providing a protective layer 11 around the pipeline 10 and further movably providing a rotating layer 12 around the protective layer 11, the anti-wear and anti-impact capabilities of the pipeline 10 are enhanced. The fixed connection between the limiting block 21 and the limiting groove 20 ensures the stability of the protective layer 11. The design of the rotating ring 23 and the rolling balls 25 between the rotating layer 12 and the protective layer 11 allows the rotating layer 12 to rotate flexibly when the pipeline 10 traverses complex terrains or is subjected to external forces, dispersing and reducing the direct impact on the pipeline 10 and the frictional force of the soil layer on it, improving the stability and orientation during the traversing process, reducing jamming phenomena, thus effectively extending the service life of the pipeline 10, reducing the difficulty of the pipeline 10 traversing the soil layer, and reducing the maintenance cost.

[0018] Specifically, a plurality of guiding strips 13 are provided on the outer periphery of the rotating layer 12, and the guiding strips 13 are spirally wound around the outer periphery of the rotating layer 12.

[0019] In this embodiment, by providing a plurality of spirally wound guiding strips 13 on the outer periphery of the rotating layer 12, the contact area between the coating tape and the soil or surrounding medium is increased, the stability and orientation during the traversing process are improved, and a certain spiral propulsion force can be generated during the advancement of the pipeline 10, which helps the pipeline 10 to more smoothly traverse obstacles, reduces jamming phenomena, and improves the construction efficiency.

[0020] Specifically, the limiting grooves 20 provided on the outer periphery of the pipeline 10 and the rotating grooves 22 provided on the outer periphery of the protective layer 11 are arranged in an interleaved manner.

[0021] In this embodiment, by arranging the limiting grooves 20 on the outer periphery of the pipeline 10 and the rotating grooves 22 on the outer periphery of the protective layer 11 in an interleaved manner, the stability and load-bearing capacity of the structures of the protective layer 11 and the rotating layer 12 are enhanced. The fixed connection between the limiting grooves 20 and the limiting blocks 21 provides support for the protective layer 11, and the interleaved rotating grooves 22 ensure that while the rotating layer 12 maintains flexibility, it will not affect the stability of the overall structure due to excessive deformation, thus ensuring the safe traversing of the pipeline 10 under various complex conditions.

[0022] Specifically, there are a plurality of mounting grooves 24 formed by the rotating grooves 22 and the rotating rings 23, and the space of the mounting grooves 24 opened at the lower end of the rotating rings 23 is larger than the mounting grooves 24 opened inside the rotating grooves 22.

[0023] In this embodiment, a plurality of mounting grooves 24 are provided between the rotating groove 22 and the rotating ring 23, and the space of the mounting groove 24 at the lower end of the rotating ring 23 is made larger than the internal space of the rotating groove 22, thereby enhancing the connection strength and stability between the rotating ring 23 and the protective layer 11. The flexible rolling of the rolling ball 25 in the multi-layer mounting groove 24 reduces the friction resistance during the rotation process, and also improves the adaptive ability of the rotating layer 12, so that it can better adapt to different terrains and crossing conditions, thereby ensuring the smooth crossing of the pipeline 10.

[0024] Specifically, the cross section of the rotating ring 23 is T-shaped.

[0025] In this embodiment, the rotating ring 23 adopts a T-shaped cross-section design to enhance the rigidity and stability of the rotating ring 23, so that it can maintain structural integrity and is not easily deformed when subjected to greater pressure and torque. At the same time, the T-shaped design also optimizes the movement trajectory of the rolling ball 25 in the mounting groove 24, reduces sticking and wear during the rolling process, and further improves the durability and reliability of the rotating layer 12.

[0026] The working principle and use process of the utility model are as follows: first, the covering belt is put on the pipeline 10, ensuring that the protective layer 11 is close to the pipeline 10 and the limiting block 21 is fixed in the limiting groove 20, then, the rotating layer 12 is installed, the rotating ring 23 is embedded in the rotating groove 22, and it is ensured that the rolling ball 25 rolls flexibly in the installation groove 24, and the directional drilling equipment is started. During the advancement of the pipeline 10, the rotating layer 12 flexibly rotates with the changes in the terrain to reduce friction and resistance. At the same time, the guide strip 13 assists in guiding and improves the crossing efficiency. The state of the covering belt is monitored throughout the process, and timely maintenance is performed to ensure that the pipeline 10 safely crosses to the target position.

[0027] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
