Description

Technical Field

[0001] This invention relates to the field of pipeline docking technology, and in particular to a precision docking auxiliary device for horizontal laying of large-diameter pipelines. Background Technology

[0002] With the acceleration of urbanization and the rapid development of residential construction projects in my country, especially the construction of numerous high-rise and mid-rise residential communities, the demand for large-diameter pipes for municipal water supply and drainage within and around these communities has increased significantly. These pipes typically refer to steel, concrete, or plastic pipes with a diameter of 600mm or more, primarily used for the community's main water supply, sewage collection, rainwater drainage, and fire-fighting water supply systems. In residential community construction, the precise connection of multiple long-distance horizontal laying sections of large-diameter pipes is a crucial step in ensuring the stable operation of the community's water supply and drainage system, residents' convenience, and the overall safety of the pipe network.

[0003] Traditional pipeline laying and connection methods primarily rely on crane lifting, roller supports, or simple brackets for initial positioning, followed by manual measurement, adjustment, and alignment. While this method is adequate for small- to medium-diameter pipelines, it becomes problematic for large-diameter pipelines. The large weight, length, and rigidity of these pipes lead to insufficient connection precision and uneven joint gaps, affecting network sealing, transport efficiency, and subsequent safety. Furthermore, the high intensity, low efficiency, and frequent adjustments of manual labor not only extend the construction period and increase costs but also pose risks of pipeline tipping and personnel safety.

The translation drive component 320 drives the hoisting module 300 and the entire pipe to slide smoothly on the stabilizing base 200 by outputting axial driving force, thereby realizing precise fine adjustment of the distance between the two pipe sections. An end platform 400 is provided at the end of the pipe 130 to be connected, and a lifting and hoisting assembly 500 that cooperates with the end platform 400 is provided on the stable base frame 200.

In use, the intermediate connecting assembly 120 is located between the two end platforms 400. The two end platforms 400 are pre-locked by the intermediate connecting assembly 120, which creates a stable and coaxial guide channel for the two pipe sections, thereby eliminating the influence of uneven ground on the connection accuracy.

[0023] Furthermore, the hoisting module 300 includes a hoisting base frame 310 that slides with the stabilizing base frame 200 and cooperates with the translation drive assembly 320.

The contact damping unit 345 is made of rubber or polyurethane, which can effectively absorb pipe vibration and impact force and prevent minor misalignment during the docking process.

[0029] Preferably, the abutment clamping arm 346 has an L-shaped structure, and the abutment clamping arm 346 is provided with an abutment pad 347 that mates with the pipe 130 to be docked.

A stable clamping assembly 150 is provided on the stable platform 140, and the structure of the stable clamping assembly 150 is consistent with the structure of the end clamping assembly 700. This double-end platform design ensures that the entire pipe section is constrained within a stable horizontal reference frame, completely solving the end warping problem caused by the "cantilever beam bending" effect of long pipes due to their own weight.

[0042] The structure of the stabilizing sling assembly 160 is identical to that of the lifting and hoisting assembly 500; alternatively, the basic structure of the stabilizing sling assembly 160 is identical to that of the lifting and hoisting assembly 500, but excludes the design of structures such as the end crossbar 560, lifting positioning frame 570, first locking unit 580, and second locking unit 590 that slide with the stabilizing base frame 200. These structures exist independently of the stabilizing base frame 200. This independent design simplifies the support system at the non-connecting ends, reducing costs while maintaining necessary stability.

[0043] The technical features of this invention not described can be implemented by or using existing technology, and will not be repeated here. Of course, the above description is not a limitation of this invention, and this invention is not limited to the examples above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this invention should also be within the protection scope of this invention.
