[0002] In the prior art, corrugated pipe expanders, as a key compensating element, are widely used to absorb axial, lateral and angular displacements caused by factors such as temperature changes, mechanical vibrations or foundation settlement. Traditional corrugated pipe expander stretching devices often have complex structures, are inconvenient to operate, and are difficult to ensure uniform stress during the stretching process, which can easily lead to deformation or damage of the corrugated pipe, thereby affecting its compensation effect and service life. In addition, traditional devices usually lack effective positioning and stabilizing mechanisms, which further limits their application range and performance. Therefore, developing a new type of stretching device with simple structure, easy operation and ensuring the safety and stability of the corrugated pipe during the stretching process is of great significance to improve the quality and reliability of corrugated pipe expanders.

[0010] Compared with the prior art, the utility model has the advantages that:

[0011] 1. Simple structure and convenient operation: by using the hydraulic cylinder, guide column and guide rail, the device can realize stable stretching of the corrugated pipe expander. The movement of the sliding seat along the guide rail ensures the linearity in the stretching process, and the hydraulic cylinder provides uniform and controllable force, making the operation more convenient and safe

[0012] 2. Ensure uniform stress: the application of the hydraulic cylinder ensures that the corrugated pipe expander can be subjected to uniform pressure during the entire stretching process, avoiding deformation or damage problems caused by local stress concentration. This helps to maintain the shape and functional integrity of the corrugated pipe expander, prolonging its service life.

[0013] 3.

[0014] 4. Effective positioning and clamping mechanism: the design of the first fixed clamp and the second fixed clamp, especially the combination of the threaded rods and the clamping blocks, provides a reliable clamping method for the corrugated pipe expander. Such design not only facilitates the installation and removal of the corrugated pipe expander, but also can adapt to corrugated pipes of different sizes, expanding the application range of the device.

[0015] 5. Protect the corrugated pipe expander: the addition of the buffer can absorb the remaining energy at the end of stretching, preventing the impact caused by sudden stop and protecting the corrugated pipe expander from possible damage. In addition, the precise alignment between the first and second fixed clamps also helps to reduce the twisting or lateral deviation of the corrugated pipe expander during the stretching process.

[0016] In summary, the bellows expander stretching device uses hydraulic cylinders, guide posts and guide rails to ensure smooth and linear stretching, and is easy and safe to operate. The hydraulic cylinders provide uniform force, avoid stress concentration, protect the shape and function of the bellows, and prolong the service life.

The threaded rods and clamping blocks of the fixed clamps are designed to facilitate the installation of bellows of different sizes, expanding the application range. The buffer absorbs residual energy, prevents impact damage, the clamps are accurately aligned to reduce distortion or deviation, and the bellows expander is comprehensively protected.
