The core components and functions:
1. Clamp body structure
Dual-cylinder clamp design: This innovative design employs a hydraulic-driven dual-cylinder system that synchronously maneuvers the jaws, ensuring a balanced and secure grip on the drill pipe, thus offering enhanced efficiency and reliability compared to traditional single-sided methods.
Floating pin mechanism: The ingenious floating pin, supported by a spring, automatically adjusts for any displacement deviation while threading the drill pipe, thereby enhancing the precision and efficacy of make-up and break-out operations.

2. Hydraulic drive system
Hydraulic Cylinder and Piston: Masterfully engineered, this system utilizes a solenoid valve to deftly control the direction of the oil circuit. With precision, it drives the piston to slide, thereby propelling the jaw support to gracefully extend and retract, ensuring seamless clamping and releasing actions in perfect harmony.
Sealing Technology: Our state-of-the-art oil pouring cup leak-proof structure, combined with an innovative back-clamp sealing pin, dramatically mitigates the risk of hydraulic oil leakage, safeguarding both performance and environment.

3. Clamping Actuator
Replaceable Jaw Module: Featuring an advanced jaw, meticulously verified by ANSYS static analysis, this module significantly reduces stress concentration on the drill pipe. Its rapid replacement feature allows for swift adaptability to drill pipes of various specifications ranging from φ87 to φ203mm.
Anti-Loosening Device: Outfitted with a robust mechanical anti-loosening mechanism and dual PLC control, this device steadfastly prevents any accidental clamp loosening during operations, ensuring unwavering reliability.

4. Auxiliary Function Components
Shock Absorption System: Seamlessly integrated with a shock absorption spring and guide shaft, this system efficiently absorbs drill string vibration energy, thereby safeguarding the integrity of the clamp structure.
Anti-Torque Frame: This ingenious frame transmits anti-torque to the Top Drive body through a rigid connection, guaranteeing unparalleled operational stability and reliability.

5. Safety and Adaptability Design
Retaining Wall Support Structure: Expertly designed to thwart lateral displacement, this structure significantly enhances the anti-eccentric load capacity, ensuring optimal performance under challenging conditions.
Modular Interface: Engineered for versatility, it adapts seamlessly to mainstream Top Drive models like the TDS11SA, supporting quick disassembly and assembly for maximum convenience and efficiency.
