[0002] In marine engineering construction and installation, regardless of the gathering and transportation method used for extracted oil and gas, subsea pipelines are the most important component of marine engineering and a major part of the offshore oil and gas field development and production system. At the same time, subsea pipelines are also the fastest, safest, and most economical and reliable means of continuously transporting large quantities of oil and gas.

[0003] As an indispensable part of marine engineering construction, the laying of subsea pipelines and the research on specialized equipment have always been key research areas in the field of offshore oil engineering. S-type offshore pipelaying vessels are specialized equipment for laying subsea pipelines, and polyurethane rollers are indispensable auxiliary components for pipeline transportation on these vessels. The main function of polyurethane rollers is to transport and protect pipelines, ensuring they are moved within designated tracks. Therefore, the wear resistance, anti-slip properties, and pressure resistance of polyurethane rollers directly affect the overall progress of offshore pipelaying construction.

[0004] Most polyurethane rollers on the market are one-piece structures. Over time, their surfaces will wear down, causing pipeline misalignment during transport. Therefore, worn rollers need to be replaced periodically. However, replacement requires replacing the entire roller, which leads to resource waste and increased production costs. To address this issue, we provide a polyurethane roller with an easily replaceable anti-slip layer to solve the above problems. Summary of the Invention

[0036] The quick-release assembly includes a drive shaft 7, which is fixedly connected to the inner wall of the mounting hole 4 via a bearing. A driven gear 8 is fixedly connected to the other end of the drive shaft 7. A drive gear ring 9 meshes with the surface of the driven gear 8. The surface of the drive gear ring 9 is fixedly connected to the inner wall of the mounting groove 3 via a bearing. A drive bevel gear 10 is fixedly connected to the surface of the drive shaft 7. A driven bevel gear 11 meshes with the surface of the drive bevel gear 10. A threaded rod 12 is fixedly connected to the surface of the driven bevel gear 11. The surface of the threaded rod 12 is fixedly connected to the inner wall of the moving groove 5 via a bearing seat. A pin tube 13 is threadedly connected to the surface of the threaded rod 12.

[0037] Specifically: the mounting groove 3 adopts a ring design and is connected to the mounting hole 4, which enables the transmission structure to cooperate with each other. The pin hole 6 can cooperate with the pin tube 13 to limit and support the anti-slip sleeve 2, so that it will not shake. In addition, by setting multiple sets of limiting mechanisms, the stability of the connection can be guaranteed. The thread has a self-locking function, so after the anti-slip sleeve 2 is limited and fixed, it will not easily shake. The roller body 1 and the anti-slip sleeve 2 are designed with an interference fit. Specific Implementation

[0038] Please see Figures 1-5 Based on the first specific embodiment, there are five mounting holes 4, which are distributed equidistantly in a circle. The pin holes 6 and the moving grooves 5 are connected in a one-to-one correspondence. Both the pin holes 6 and the moving grooves 5 adopt a rectangular hole design. The surface of the drive gear ring 9 is provided with countersunk holes, which are hexagonal in design. There are four sets of driven gears 8, with five gears in each set. The inner cavity of the pin tube 13 is provided with threaded holes for use with the threaded rod 12.

The roller body 1 is made of polyurethane, and the anti-slip sleeve 2 is made of ceramic with anti-slip texture on its surface. Lubricating grease is applied between the inner wall of the drive gear ring 9 and the end shaft of the roller body 1.

[0039] Specifically: multiple sets of mounting holes 4 can install multiple sets of transmission components, ensuring connection stability; rectangular pin holes 6 and moving grooves 5 can be used with rectangular pin tubes 13 to limit their movement and ensure stable displacement; the hexagonal countersunk hole design facilitates the rotation of the drive gear ring 9 by external tools; multiple sets of driven gears 8 can firmly limit and fix the anti-slip sleeve 2; the threaded hole and threaded rod 12 can drive the pin tube 13 to move stably; the polyurethane roller body 1 and the ceramic anti-slip sleeve 2 provide them with an ultra-long service life and wear resistance; grease can lubricate the connection between the drive gear ring 9 and the roller body 1, thus ensuring the smooth rotation of the drive gear ring 9.
