Description

Technical Field

[0001] This utility model belongs to the technical field of tooling for pipeline construction, and in particular relates to a pipeline transportation compensation support device. Background Technology

[0002] Pipeline support fixtures play a crucial role in pipeline engineering. Their primary function is to provide stable and reliable support for pipelines, ensuring they maintain their predetermined spatial position during construction and transportation. This prevents construction accuracy or pipeline performance from being affected by bending, settling, or displacement. Properly designed support fixtures can effectively distribute the weight and stress of the pipeline, reducing direct contact between the pipeline and the ground or other equipment, preventing damage caused by friction or collision. Furthermore, the use of pipeline support fixtures can improve construction efficiency, facilitate pipeline transportation, installation, and maintenance, thereby ensuring project quality and extending pipeline service life.

[0003] Current pipeline construction support methods suffer from several drawbacks and deficiencies, severely impacting construction efficiency and quality. Firstly, the design of roller support assemblies results in uneven distribution of support force on the pipeline. Particularly during directional drilling, the pipeline is pulled into the borehole under the pullback force, and this uneven support leads to excessive local pressure, easily damaging the pipeline's anti-corrosion layer. Secondly, changes in ground conditions further exacerbate the support problem. When the ground is uneven, the roller support assemblies struggle to provide uniform support, leading to increased pressure at the roller-pipe contact points and significantly increasing the risk of damage to the anti-corrosion layer. Furthermore, as construction progresses, ground settlement may further deteriorate the support capacity of the roller support assemblies, exacerbating the problem. Thirdly, due to site terrain limitations, roller support assemblies are often not placed vertically, with some rollers potentially installed at an angle, further exacerbating the uneven support force and causing some contact points to experience excessive pressure and breakage. Finally, these defects necessitate frequent pipeline inspections and repairs by construction quality management personnel, reducing construction efficiency and increasing safety hazards. These problems indicate that there is still considerable room for improvement in the existing pipeline support methods during construction. Utility Model Content

The outer support is connected to the outside of the idlers via a support spring.

[0006] In the above technical solution, preferably, a support block is fixed on the inner side of the base, and the two ends of the pull spring are respectively connected to the outer support of the roller and the support block.

[0007] In the above technical solution, preferably, the inner support of the idler roller includes an inner bridge seat, a lifting support, a vertical guide rod, and a pushing screw. The inner bridge seat is fixed to the middle of the base. The inner bridge seat includes a support leg and an upper seat plate.

The lifting support is installed at the upper end of the vertical guide rod. The pushing screw is vertically arranged and threadedly fitted to the upper seat plate. The upper end of the pushing screw touches the lifting support. The two sides of the lifting support are hinged to the inner ends of the two idler rollers through pins.

[0010] In the above technical solution, preferably, the two ends of the pull spring are detachably connected to the outer support of the roller and the support block, respectively.

[0014] The pipeline transportation compensation support device has a series of innovative advantages and effects, which can comprehensively improve the support stability, pipeline protection and construction efficiency during the pipeline transportation process.

[0015] First, the device employs a bidirectional elastic support structure for the idler rollers, a design that provides more uniform and stable support for the pipeline. Traditional support methods suffer from uneven support forces, which can easily lead to excessive stress on certain parts of the pipeline, thereby damaging the pipeline's anti-corrosion coating. The bidirectional elastic support effectively disperses the stress on the pipeline, ensuring uniform stress during transportation and avoiding excessive local pressure, thus effectively protecting the anti-corrosion coating and extending the pipeline's service life.

[0016] Secondly, the triangular compensating support structure formed by the elastic support device and the roller has unique adaptability and flexibility. During pipeline construction, factors such as ground settlement, pipeline bending, and uneven lateral stress can all cause changes in the pipeline's position and stress conditions. Traditional support devices struggle to provide stable support under these circumstances, while the compensating support device, through its triangular structure design, can flexibly adjust the support direction and stress distribution, automatically adapting to changes in ground conditions and pipeline stress states, maintaining pipeline stability, and preventing damage caused by uneven support.

[0017] Furthermore, the innovative design of this device effectively reduces excessive pressure caused by misalignment of the rollers or uneven ground during pipeline pullback. Ground settlement and unevenness can lead to misalignment of the roller support assembly, resulting in excessive pressure on some rollers in contact with the pipeline, thereby damaging the pipeline's anti-corrosion coating. The compensating support device, through its precise elastic support and triangular compensation structure, can eliminate the effects of uneven ground and misalignment, ensuring uniform distribution of support force, avoiding excessive local pressure, and fundamentally preventing damage to the anti-corrosion coating.

[0018] The device also features strong automatic adjustment capabilities, enabling it to automatically compensate for uneven support based on pipeline transport processes, ground conditions, and changes in external stress. This minimizes the risk of uneven support caused by human error or terrain variations. This intelligent support method not only reduces reliance on construction personnel but also significantly improves construction efficiency and accuracy, reducing the frequency of manual repairs to the pipeline's anti-corrosion coating.

[0019] In practical applications, pipeline transport compensation support devices can significantly improve the quality of directional drilling. By providing uniform support force, they protect the pipeline's anti-corrosion layer from damage and ensure that the pipeline is not affected by uneven external pressure during construction, avoiding damage or deformation caused by insufficient or excessive support force. For the safe operation of gas pipeline networks, this device provides strong protection, reducing safety hazards and the probability of accidents.

[0020] In summary, pipeline transportation compensation support devices play a crucial role in pipeline construction. Through innovative design, they address the shortcomings of traditional support methods, possessing the capabilities of uniform support, automatic compensation, and flexible adaptation to ground changes. They effectively protect the pipeline's anti-corrosion layer, improve construction efficiency, ensure pipeline safety and long-term operation, and provide strong guarantees for the quality of directional drilling and the safe operation of gas pipeline networks.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0025] To address the problems of uneven support force distribution, uneven ground surface, misalignment of roller support assemblies, and ground settlement in current pipeline construction support methods, this utility model provides a pipeline transportation compensation support device. To further illustrate the structure of this utility model, a detailed description is provided below in conjunction with the accompanying drawings:

[0026] Please see Figure 1A pipeline conveying compensation support device includes a base 1, two V-shaped idler rollers 2, an inner idler roller support 3, and an outer idler roller support 4. The inner end of each idler roller is hinged to the inner idler roller support, and the outer end of each idler roller is hinged to the outer idler roller support. The inner idler roller support is mounted on the base. The base provides support and a mounting foundation for the overall structure; in this embodiment, the base is a flat plate. The two idler rollers are arranged in a V-shape to support and guide the pipeline, ensuring its stability during conveying. Each idler roller can rotate around its own axis. The inner and outer idler roller supports are hinged to the inner and outer ends of the idler rollers, respectively, providing rotational support for the idler rollers.

[0027] The outer support of the idler roller is mounted on the base via a linear guide rail 5. The movement direction of the outer support is perpendicular to the V-shaped surface of the V-shape. Specifically, the linear guide rail is a dovetail guide block fixed to the base with screws. The outer support of the idler roller has a dovetail groove that engages with the dovetail guide block, allowing the outer support to move laterally linearly along the dovetail guide block. A tension spring 6 connects the outer support of the idler roller to the base, applying an inward elastic force to the outer support. Specifically, a support block 7 is fixed to the inner side of the base, and the two ends of the tension spring are connected to the outer support of the idler roller and the support block, respectively. The outer support of the idler roller is connected to the outside of the idler roller via a support spring 8.

[0028] By combining tension springs and support springs, the support device provides bidirectional elastic support when the pipeline shifts or deforms, ensuring that the outer support of the idler roller can be flexibly adjusted to adapt to different working conditions and changes in the pipeline, thereby avoiding excessive stress or displacement restrictions on the pipeline. The bidirectional elastic support effectively balances the external pressure and internal elastic restoring force of the pipeline under different conveying conditions, keeping the pipeline in a reasonable working position and preventing excessive displacement or damage to the device due to external impacts or load changes. The dual-spring design provides a more balanced and continuous support force, not only increasing the stability of the support system but also reducing the impact of vibration and irregular displacement on the pipeline, extending the system's service life. The bidirectional springs and the axis of the idler roller form a triangular support structure. From a mechanical perspective, this design significantly improves the support stability and load-bearing capacity of the pipeline. The triangular support structure distributes the force evenly at the support point, reducing stress concentration and helping to mitigate the risk of pipeline deformation or damage. Furthermore, this structure has strong anti-overturning capabilities, effectively preventing the pipeline from tilting or shifting when subjected to external forces or load changes. By optimizing force distribution and improving overall bending resistance, this design enhances the stability and reliability of pipeline transportation, ensuring the pipeline can operate safely for extended periods.

[0029] The inner support for the idler roller includes an inner bridge seat 3-1, a lifting support 3-2, a vertical guide rod 3-3, and a pushing screw 3-4. The inner bridge seat is fixed to the middle of the base and includes a support leg and an upper seat plate. The support leg is fixed to the base and supports the horizontally arranged upper seat plate, forming a bridge-like plate. The upper seat plate is fitted with the vertical guide rod through vertical guide holes. The vertical guide rod is located at the four corners of the rectangular upper seat plate. The lifting support is installed at the upper end of the vertical guide rod. The pushing screw is vertically arranged and threaded onto the upper seat plate. The upper end of the pushing screw contacts the lifting support. The two sides of the lifting support are hinged to the inner ends of the two idler rollers via pins. By rotating the pushing screw, the lifting support can be lifted, thereby adjusting the V-shaped angle to accommodate idler rollers of different sizes.

[0030] The outer support of the idler roller is equipped with a locking component for locking its position on the linear guide rail. Specifically, in this embodiment, N positioning pin holes are evenly distributed along the length of the dovetail guide block. The locking component is a locking pin 9 installed on the outer support of the idler roller that engages with the positioning pin holes. The locking pin is inserted into the positioning pin hole to position the outer support of the idler roller at the corresponding positioning pin control position. This makes the outer support of the idler roller a fixed support, and the tension spring becomes ineffective.

[0031] The two ends of the pull-up spring are detachably connected to the outer support of the idler roller and the support block, respectively. Specifically, the inner side of the outer support of the idler roller has symmetrically arranged slots on both sides, and the end face of the support block opposite to the outer support of the idler roller also has symmetrically arranged slots on both sides. The two ends of the pull-up spring are connected to insert plates that are inserted from top to bottom through the side slots. With the outer support of the idler roller fixed, the pull-up spring can be removed to prevent aging of the pull-up spring when not in use and to reduce the weight of the equipment.

[0032] Please see Figure 2 and Figure 3 The idler roller's outer support is mounted with a fixed-length support rod 10 via a flipping shaft. The axis of the flipping shaft is perpendicular to the V-shaped surface of the V-shape. The outer end of the idler roller is connected to an outer seat block 11, which has a support portion that forms a support structure with the fixed-length support rod. The fixed-length support rod is threaded with a support nut 12. The support portion is a support plate with an outer opening. The shaft length of the flipping shaft is required to ensure that the fixed-length support rod can be adjusted to a certain length. The fixed-length support rod flips and engages with the opening, and the support nut pushes against the support portion, transforming the idler roller into a rigid support. This allows the support device to have both rigid and flexible support modes.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
