Function and Characteristics of Rotation Spherical Hinge

I. Main Functions of Rotation Spherical Hinge

The rotation spherical hinge is the core load-bearing and rotation device in bridge rotation construction. Its main functions include:

1. Bearing Bridge Weight: Supports the upper structure of the bridge, 130000KN, 1.5-ton Bridge Railway Rotation Spherical Hinge Processing Including Rotation Installation, Rotation Weighing, and Other Supporting Related Equipment bearing loads of thousands of tons or even tens of thousands of tons.
2. Achieving Smooth Rotation: Through low-friction design, enables the bridge to rotate smoothly under traction or jacking.
3. Precise Positioning: Ensures accurate alignment with the design position after bridge rotation, with errors controlled at the millimeter level.
4. Adapting to Complex Forces: Withstands dynamic loads, 130000KN, 1.5-ton Bridge Railway Rotation Spherical Hinge Processing Including Rotation Installation, Rotation Weighing, and Other Supporting Related Equipment eccentric loads, wind loads, etc., during the rotation process.

II. Characteristics of Rotation Spherical Hinge

1. Structural Features

• Upper and Lower Spherical Hinge Coordination: The upper spherical hinge (rotating part) and lower spherical hinge (fixed part) are matched through high-precision machining to ensure smooth rotation.
• Friction Pair Design: Uses high-performance materials (e.g., PTFE-stainless steel, copper-based alloys) to reduce the friction coefficient (typically ≤0.05).
• Lubrication System: Built-in lubricating grease channels to reduce friction and wear, extending service life.
• Positioning Device: Equipped with limit pins or guiding structures to prevent deviation during rotation.

2. Performance Features

• High Load Capacity: A single spherical hinge can bear ten-thousand-ton-level bridges, suitable for 130000KN, 1.5-ton Bridge Railway Rotation Spherical Hinge Processing Including Rotation Installation, Rotation Weighing, and Other Supporting Related Equipment large-span rotation bridges.
• Low Friction, High Stability: Smooth rotation process without jamming or vibration.
• Corrosion Resistance: Surface coating or stainless steel material adapts to long-term outdoor use.
• Modular Design: Facilitates transportation, installation, and later maintenance.

3. Construction Adaptability

• Suitable for Various Rotation Methods: Horizontal rotation, vertical rotation, or combined horizontal and vertical rotation.
• Adapts to Complex Environments: Can be used in high-risk areas such as crossing railways, highways, and rivers.
• Reusability: Some spherical hinges are designed to be detachable and reusable in other projects.

III. Key Technical Indicators of Rotation Spherical Hinge

IV. Application Advantages

• High Safety: Reduces high-altitude operations and lowers construction risks.
• High Efficiency: Short rotation construction time (typically completed within hours), shortening the project duration.
• Good Economy: Saves temporary support costs compared to traditional scaffolding methods.
• Environmental Friendliness: Reduces interference with traffic and the environment.
