A supporting hose 2 is provided inside the corrugated pipe 1. The connecting structure is installed on the corrugated pipe 1 and includes a connector 3, a guide block 4, a sealing ring 5, and a guide groove.

[0037] The guide groove is opened on the support hose 2, the connector 3 is installed at one end of the bellows 1, the guide block 4 is installed on the connector 3, the sealing ring 5 is installed on the connector 3, and the connector 3 is inserted into the connecting hose along the guide groove direction through the guide block 4.

[0038] It should be noted that the support hose 2 is embedded inside the corrugated pipe 1. To prevent the support hose 2 from separating from the corrugated pipe 1, the two are bonded together with adhesive to enhance the strength of the corrugated pipe 1. The support hose 2 installed inside the corrugated pipe 1 also prevents leakage caused by damage to the corrugated pipe 1. The end of the support hose 2 that contacts the connector 3 has a beveled structure, and the end of the connector 3 also has a beveled structure. The beveled structures of the support hose 2 and the connector 3 are installed together by interference fit. To prevent poor sealing at the connection, after installation, sealant is applied to the edge of the connection between the corrugated pipe 1 and the connector 3 to ensure a good seal at the connection. A guide groove is opened on the inner wall of the support hose 2, and a guide block 4 is provided on the connector 3. The guide block 4 on the connector 3 is inserted into the guide groove of the support hose 2. A sealing ring 5 is provided at the contact point between the connector 3 and the corrugated pipe 1 to prevent leakage.

[0039] In the specific implementation process, the connector 3 is provided with a positioning groove for installing the sealing ring 5;

[0040] It should be noted that the positioning groove on the connector 3 facilitates the installation and positioning of the sealing ring 5.

[0041] In the specific implementation process, the contact area between the bellows 1 and the positioning component is coated with sealant to ensure a good sealing effect at the connection.

[0042] In the specific implementation process, it includes a base 6, a support frame 7, and a pipe fitting installation device. The support frame 7 is installed on the base 6, and the pipe fitting installation device is installed between the base 6 and the support frame 7. The pipe fitting installation device includes a moving structure, a positioning structure, and a lifting structure. The moving structure is installed between the support frame 7 and the base 6, the positioning structure is installed on the moving structure, and the lifting structure is installed on the moving structure. The moving structure includes a lead screw module 8, a mounting base 9, a connecting frame 10, a guide rail 11, a moving base 12, and a support rib plate 13.

[0043] The lead screw module 8 is mounted on the support frame 7, the mounting base 9 is mounted on the moving end of the lead screw module 8, the guide rail 11 is mounted on the base 6, the moving base 12 is mounted on the guide rail 11, the connecting frame 10 is mounted between the moving base 12 and the moving end of the lead screw module 8, and the support rib 13 is mounted on the connecting frame 10.

[0044] It should be noted that the MPVE-blended reinforced double-wall corrugated pipe 1 is a new type of pipe made of polyvinyl chloride and polyethylene, featuring an annular outer wall and a smooth inner wall. During the production of the corrugated pipe 1, to facilitate the connection between corrugated pipes 1, connectors 3 are installed at both ends of the corrugated pipe 1. When the connectors 3 are installed with the corrugated pipe 1, the corrugated pipe 1 is mounted on the base 6 and fixed. A fixing sleeve is provided on the base 6 to limit the position of the corrugated pipe 1. The connectors 3 are then installed on the pipe fitting installation device. The pipe fitting installation device moves the connectors 3 and inserts them into the corrugated pipe 1, completing the installation. The support frame 7 supports the pipe fitting installation device. The pipe fitting installation device includes a moving structure, a positioning structure, and a lifting structure. Through the cooperation between the components of the moving structure, the connector 3 and the corrugated pipe 1 can be easily installed without manual insertion by workers, which is convenient and quick. Through the cooperation between the components of the positioning structure, a suitable positioning block can be selected according to the size of the corrugated pipe 1 to position the connector 3 of the corrugated pipe 1. The replacement and installation of the positioning block is convenient and quick, and the positioning of the connector 3 is stable and will not damage the connector 3. Through the cooperation between the components of the lifting structure, the installation of the first positioning block 16 is convenient, without the need for manual lifting of the positioning block, avoiding worker injury and saving installation time.

[0045] The lead screw module 8 includes a motor, lead screw, slider, and slide bar, and is used as a drive unit. The motor drives the lead screw to rotate, and the rotation of the lead screw drives the slider to move along the slide bar direction, thereby driving the moving structure mounted on the slider to adjust its position. The lead screw module 8 is a known technology. The mounting base 9 is installed on the moving end of the lead screw module 8. When the lead screw module 8 starts, it drives the mounting base 9 to move. One end of the connecting frame 10 is connected to the drive end of the lead screw module 8, and the other end is connected to the moving seat 12 mounted on the guide rail 11. When the lead screw module 8 drives the connecting frame 10 to move, the moving seat 12 moves along the guide rail 11 through the connecting frame 10, and moves and stops synchronously. This realizes the smooth movement of the positioning structure installed between the mounting base 9 and the moving seat 12, which facilitates the installation of the bellows 1 and the connecting part 3.

[0046] In the specific implementation process, guide rail 11 has an I-shaped structure;

[0047] It should be noted that the guide rail 11 has an I-shaped structure, which facilitates the smooth movement of the movable seat 12 mounted on the guide rail 11.

[0048] In the specific implementation process, the positioning structure includes a lifting cylinder 14, a connecting seat 15, a first positioning block 16, a second positioning block 17, and a limiting component;

[0049] The lifting cylinder 14 is mounted on the mounting base 9 at the drive end of the lead screw module 8, the connecting base 15 is mounted on the telescopic end of the lifting cylinder 14, the first positioning block 16 is mounted on the connecting base 15, the second positioning block 17 is mounted on the moving base 12, and the limiting component is set between the first positioning block 16 and the connecting base 15 and between the second positioning block 17 and the moving base 12.

[0050] It should be noted that the first positioning block 16 is installed on the connecting seat 15 through the limiting component, the second positioning block 17 is installed on the moving seat 12 through the limiting component, and the lifting cylinder 14 is installed on the mounting seat 9. The first positioning block 16 and the second positioning block 17 are the same size and shape. The connecting piece 3 is placed on the second positioning block 17, and the lifting cylinder 14 is started. The lifting cylinder 14 drives the first positioning block 16 installed on the connecting seat 15 to move downward. Through the cooperation of the first positioning block 16 and the second positioning block 17, the connecting piece 3 placed on the second positioning block 17 is positioned and clamped. The lead screw module 8 is started, which drives the moving seat 12 and the mounting seat 9 to move towards the bellows 1. The positioning structure is installed between the moving seat 12 and the mounting seat 9. When the lead screw module 8 is started, the positioning piece is inserted into the bellows 1 on the base 6 under the action of the lead screw module 8, and the connection between the bellows 1 and the connecting piece 3 is completed.

[0051] In the specific implementation process, positioning holes are provided on the first positioning block 16 and the second positioning block 17;

[0052] It should be noted that both the first positioning block 16 and the second positioning block 17 are provided with positioning holes, which facilitate the installation and positioning of the positioning pin 19 in the limiting assembly.

[0053] In the specific implementation process, the limiting component includes an electromagnetic chuck 18, four positioning pins 19 and two connecting blocks 20;

[0054] The electromagnetic chuck 18 is mounted on the connecting seat 15, the connecting block 20 is mounted on the first positioning block 16 and works in conjunction with the electromagnetic chuck 18, and the positioning pins 19 are evenly inserted into the connecting seat 15 and the movable seat 12 respectively, and pass through the first positioning block 16 and the second positioning block 17 respectively.

[0055] It should be noted that the first positioning block 16 moves upward through the lifting structure. When the connecting block 20 on the first positioning block 16 is inserted into the connecting seat 15 and comes into contact with the electromagnetic chuck 18 inside the connecting seat 15, the electromagnetic chuck is activated. The electromagnetic chuck 18 generates magnetic force to attract the first positioning block 16. There is no need for manual support of the first positioning block 16, saving manpower. Two of the positioning pins 19 are taken and inserted into the connecting seat 15. The positioning pins 19 penetrate the first positioning block 16, fixing the position of the first positioning block 16 and the connecting seat 15. The second positioning block 17 is installed on the movable seat 12. The remaining two positioning pins 19 are inserted into the movable seat 12 and penetrate the positioning holes on the second positioning block 17, fixing the position of the second positioning block 17 on the movable seat 12, thus completing the limiting of the first positioning block 16 and the second positioning block 17.

[0056] In the specific implementation process, the lifting structure includes a pair of lifting cylinders 21, a lifting block 22, a positioning rod 23, and an extension block 24;

[0058] It should be noted that, to facilitate the installation of the first positioning block 16, a lifting cylinder 21 is used to replace manual pushing of the first positioning block 16, saving manpower. The extension block 24 is snapped onto the first positioning block 16, and the positioning rod 23 is inserted into the lifting block 22 of the lifting cylinder 21. The first positioning block 16 with the extension block 24 installed is manually moved and placed on the lifting block 22. The positioning rod 23 on the lifting block 22 is inserted into the insertion hole on the extension block 24. The lifting cylinder 21 is started, and the lifting cylinder 21 rises, driving the first positioning block 16 to rise. The position of the lifting cylinder 14 is adjusted to facilitate the insertion of the first positioning block 16 into the connecting seat 15, completing the installation of the first positioning block 16. This saves manpower and avoids the first positioning block 16 slipping out of the worker's hand during the pushing process, which could cause injury.

[0059] In the specific implementation process, insertion holes are provided on the extension block 24;

[0060] It should be noted that the insertion hole on the extension block 24 is slightly larger than the diameter of the positioning rod 23, and the insertion hole facilitates the insertion of the positioning rod 23.
