Processing of 4000-ton Spherical Hinge for Swing Spherical Hinge Bearing and Installation Construction of 40,000 KN Swing Spherical Hinge

Functional Features of Swing Spherical Hinge

1. Support Function

   • Bears the entire weight of the bridge superstructure and transfers it to the substructure.

2. Rotation Function

   • Enables smooth rotation of the bridge superstructure through the coordination of the upper and lower spherical hinges.

3. Precise Alignment

   • Ensures accurate alignment of the bridge during the rotation process to meet design requirements.

4. Friction Reduction

   • The design of sliding surfaces and lubrication systems effectively reduces frictionProcessing of 4000-ton Spherical Hinge for Swing Spherical Hinge Bearing and Installation Construction of 40,000 KN Swing Spherical Hinge and minimizes the driving force required for rotation.

5. Safety

   • High-strength materials and precision design ensure safety and stability during the rotation process.

4. Urban Interchanges
   • Completes bridge construction within limited space.

IV. Construction Process of Swing Spherical Hinge

1. Design and Manufacturing

   • Design the dimensions and materials of the swing spherical hinge based on parameters such as the bridge's design load and rotation angle.Processing of 4000-ton Spherical Hinge for Swing Spherical Hinge Bearing and Installation Construction of 40,000 KN Swing Spherical Hinge
   • Manufacture using high-strength steel and wear-resistant materials to ensure quality.

2. Installation of Lower Spherical Hinge

   • Install the lower spherical hinge on the bridge substructure, ensuring its levelness and positional accuracy.

3. Installation of Upper Spherical Hinge

   • Install the upper spherical hinge on the bridge superstructure, aligning it precisely with the lower spherical hinge.

4. Installation of Sliding Surface and Lubrication System

   • Install sliding surface materials between the upper and lower spherical hinges and add lubricant.

5. Swing Construction

   • Use hydraulic jacks or other rotation equipment to drive the rotation of the bridge superstructure.Processing of 4000-ton Spherical Hinge for Swing Spherical Hinge Bearing and Installation Construction of 40,000 KN Swing Spherical Hinge
   • Monitor the angle, speed, and stress during the rotation process.

6. Fixation and Adjustment

   • After rotation is completed, fix the bridge and perform fine adjustments to ensure precise positioning.
