Description

Technical Field

[0001] The utility model relates to the technical field of pipelines, in particular to a switching device for a HDPE double-wall corrugated pipe. Background Art

[0002] HDPE double-wall corrugated pipe is a pipe made of high-density polyethylene with an inner and outer two-layer structure. The outer layer is usually a smooth surface, and the inner layer adopts a corrugated structure, which increases the flexibility and flexural resistance of the pipe, making it more suitable for applications that need to adapt to underground changes. The outer layer is usually a smooth surface, which is conducive to improving the fluid transportation efficiency of the pipeline and reducing the resistance of the fluid in the pipeline. The corrugated structure improves the flexibility of the pipeline and helps to reduce the impact of external geological changes on the pipeline. The smooth surface of the outer layer is conducive to reducing the friction resistance during fluid transportation and improving the transportation efficiency of the pipeline. HDPE double-wall corrugated pipe has been widely used in various engineering fields. Due to the limited length of double-wall corrugated pipes, multiple double-wall corrugated pipes need to be transferred when used. However, multiple double-wall corrugated pipes are generally transferred by using a transfer structure. The position of the connecting pipe is fixed, and it is difficult to transfer double-wall corrugated pipes with different installation angles, and the scope of application is limited.

[0003] Therefore, in view of the above problems, a switching device for a HDPE double-wall corrugated pipe with high applicability is now developed. Utility Model Content

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] A transfer device for HDPE double-wall corrugated pipe, such as Figure 1-Figure 3As shown, it includes a transition tube 1, a sealing ring 2, a transfer tube 3, a telescopic tube 4, an internal thread 5 and an external thread 6. The left and right parts of the telescopic tube 4 are connected to a cylindrical transfer tube 3. The middle part of the telescopic tube 4 is connected to a plurality of telescopic threads. The inside of the transfer tube 3 is connected to left-right symmetrical internal threads 5. There are two transition tubes 1 in total. One side of the transition tube 1 is connected to a guide surface for easy connection with the double-wall corrugated tube. The inside of the transition tube 1 is connected to left-right symmetrical external threads 6. The internal threads 5 are threadedly connected to adjacent external threads 6. An elastic sealing ring 2 is connected to the outer wall of one side of the transition tube 1. It also includes a clamping mechanism, which includes a clamp 7, a clamp 8 and a first groove 9. Six "L"-shaped clamps 7 are connected to the outer wall of the transfer tube 3. The inner side of the clamp 7 is connected to a plurality of clamps 8. The clamps 8 are all arc-shaped elastic convex strips, and the outer side of the clamp 7 is provided with a first groove 9.

[0020] When transferring HDPE double-wall corrugated pipes, this device can be used. It should be noted that first, the transition pipe 1 is threadedly connected to the adjacent internal thread 5 of the transfer pipe 3 through the adjacent external thread 6, and then the double-wall corrugated pipe is slid into the outer side of the transition pipe to clamp it, so that the transition pipe presses the inner surface of the double-wall corrugated pipe, and the sealing ring 2 seals and supports the inner side of the outer surface of the double-wall corrugated pipe. At this time, the clamp 7 and the adjacent clamp 8 are clamped to the outer surface of the double-wall corrugated pipe. The outside is compressed, and the compression parts 8 are thinner than the adjacent clamps 7, which enhances the deformation capacity of the clamps 7. When the two double-wall corrugated pipes need to be adjusted and switched, the telescopic tube 4 is extended and rotated to a certain angle, so as to perform micro-angle switching on the two double-wall corrugated pipes, thereby adapting to different double-wall corrugated pipe switching requirements. In summary, through the cooperation between the transition pipe 1 and the telescopic tube 4, the two double-wall corrugated pipes are switched at different angles, thereby adapting to different switching requirements of the double-wall corrugated pipes, thereby enhancing its applicability.

[0021] like Figure 1 and Figure 4 As shown, it also includes a limiting mechanism, which includes a power-assisting ring 10 and an inclined surface 12. The transfer tube 3 is connected to the power-assisting ring 10, and the left and right sides of the power-assisting ring 10 are connected to the inclined surfaces 12.

[0022] like Figure 1 and Figure 4 As shown, a second groove 11 is also included, and a plurality of second grooves 11 are formed on the boosting ring 10 .

[0023] It should be noted that when the transition pipe 1 and the adapter tube 3 are threadedly connected, the adapter personnel can drive the transition pipe 1 to rotate by rotating the power-assisting ring 10. At this time, the second grooves 11 prevent the adapter personnel's hands from slipping, thereby increasing the friction between the adapter personnel and the power-assisting ring 10, and avoiding accidental sliding and disengagement when rotating the transition pipe 1. In summary, the power-assisting ring 10 cooperates with the second grooves 11 to increase the friction between the adapter personnel and the power-assisting ring 10, and avoid accidental sliding and disengagement when rotating the transition pipe 1, thereby improving the stability of the transfer.
