[0002] The spiral tube is a kind of tube formed by winding and welding glass fiber. Due to its unique molding process, it can produce tubes with a diameter of up to 3 meters, which is difficult to achieve with other production processes. The spiral tube is mainly used for the protection of various engineering machinery and mining hydraulic equipment and wires and cables with wear-resistant requirements to prevent the wires and cables from being worn and wet. Because it can completely cover the protected product, it forms an effective wear and UV protection effect and plays a protective role outside many rod-shaped objects.

[0035] See also Figure 1-Figure 5 The utility model provides a technical solution: a winding tube, comprising: a main body 1, a winding rib 11 is arranged on the outside of the main body 1, the main body 1 and the winding rib 11 are covered with a winding layer 12, the winding layer 12 is composed of glass fiber and glass cloth, and the first butt ring 2 and the second butt ring 21 are respectively installed at both ends of the main body 1 and the winding layer 12;

[0036] The first docking ring 2 and the second docking ring 21 are both provided with docking grooves 22, the ends of the main body 1 and the winding layer 12 are located in the docking grooves 22, and docking bolts 25 are installed through the first docking ring 2, the second docking ring 21, the main body 1 and the winding layer 12;

[0037] An alignment ring 26 is installed on the surface of the second docking ring 21, an alignment groove 27 is opened on the surface of the first docking ring 2, the alignment ring 26 is located in the alignment groove 27, a sealing layer 28 is provided on the surface of the alignment ring 26, and an injection pressure pipe 3 is opened inside the second docking ring 21;

[0038] The surfaces of the first docking ring 2 and the second docking ring 21 are both provided with a locking groove 4 , a locking ring 41 is arranged in the locking groove 4 , and a rubber pad 42 is arranged on the inner wall of the locking ring 41 .

[0039] In this example, sealing gaskets 23 are provided at the contact positions of the main pipe body 1 and the winding layer 12 with the docking groove 22, and a sealing ring 24 is provided on the surface of the sealing gasket 23, which improves the tightness of the connection between the sealing gasket 23 and the main pipe body 1, the winding layer 12, the first docking ring 2 and the second docking ring 21, thereby improving the protective sealing performance.

[0040] One side of the sealing gasket 23 in this example is embedded in the inner wall of the docking groove 22, and the docking bolt 25 is connected through the sealing gasket 23, which improves the installation stability of the sealing gasket 23 and prevents the sealing gasket 23 from being displaced and affecting the sealing performance.

[0041] The sealing layer 28 in this example is located between the alignment ring 26 and the alignment groove 27. The surface of the sealing layer 28 facing the alignment groove 27 is a corrugated structure. A gap is provided between the sealing layer 28 and the alignment ring 26. The alignment ring 26 is connected to the injection and pressure pipe 3. An injection and pressure hole 29 is provided on the alignment ring 26 to facilitate the injection of inert liquid into the alignment ring 26 through the injection and pressure pipe 3. The inert liquid is injected between the sealing layer 28 and the alignment ring 26 through the injection and pressure hole 29 to expand the sealing layer 28, thereby improving the tightness of the contact between the sealing layer 28 and the alignment groove 27.

[0042] In this example, a sealing plug 32 is provided at one end of the injection and pressure tube 3 facing the alignment ring 26, and a guide groove 31 is opened on the inner wall of the injection and pressure tube 3. A guide rod 33 is fixed to the surface of the sealing plug 32, and the guide rod 33 is slidably connected to the second docking ring 21 through the guide groove 31. A return spring 34 is provided between the guide rod 33 and the inner wall of the guide groove 31, so that the sealing plug 32 can perform telescopic movement in the injection and pressure tube 3 through the guide rod 33 and the guide groove 31, which is beneficial to the opening or closing of the injection and pressure tube 3 toward one end of the alignment ring 26 and prevent the inert liquid from leaking.

[0043] In this example, one end opening of the injection and pressure tube 3 is connected to the locking groove 4, and the end opening of the injection and pressure tube 3 located in the locking groove 4 is provided with a closing plug 35. After the closing plug 35 closes the opening of the injection and pressure tube 3, the locking ring 41 in the locking groove 4 can resist the closing plug 35 to prevent it from loosening.

[0044] Working principle: According to Figure 1-Figure 5As shown, when the winding tube needs to be spliced ​​end to end, first align the first docking ring 2 on the winding tube with the second docking ring 21 on another section of the winding tube, then insert the alignment ring 26 on the second docking ring 21 into the alignment groove 27 on the first docking ring 2, and inject inert liquid into the alignment ring 26 through the injection pipe 3. At this time, the inert liquid pushes the sealing plug 32 away from the injection pipe 3 under the injection pressure, so that the injection pipe 3 is opened toward the opening of the alignment ring 26. At this time, the inert liquid is injected into the alignment ring 26 and injected into the space between the alignment ring 26 and the sealing layer 28 through the injection hole 29. At this time, the sealing layer 28 expands, lifting the sealing layer 28 to connect with the alignment groove 27. The sealing plug 35 is then tightened to seal the injection and pressure tube 3, and then the locking ring 41 is clamped in the locking groove 4 on the first docking ring 2 and the second docking ring 21, and the two locking rings 41 are locked by bolts. At this time, the two winding tubes are spliced ​​through the first docking ring 2 and the second docking ring 21. When it is necessary to replace a damaged section of the winding tube, it is only necessary to open the locking ring 41 and unscrew the sealing plug 35 to discharge the inert liquid, so that the alignment ring 26 can be pulled out of the alignment groove 27, so that the first docking ring 2 and the second docking ring 21 are disconnected, and the damaged winding tube that is disconnected can be replaced.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
