The core components and functions:
1. Clamp body structure
Dual-cylinder clamp design: The hydraulically driven dual-cylinder mechanism ensures balanced and effective clamping of drill pipes, surpassing the efficiency and reliability of traditional single-sided methods.
Floating pin mechanism: Ingeniously designed with a spring-supported floating pin, this mechanism automatically compensates for displacement deviations when the drill pipe threads are screwed together, enhancing precision during make-up and break-out operations.

2. Hydraulic drive system
Hydraulic Cylinder and Piston: The sophisticated solenoid valve expertly maneuvers the oil circuit, guiding the piston with precision to slide, thereby driving the jaw support to extend and retract. This orchestrates a seamless clamping and release action, ensuring efficiency and reliability.
Sealing Technology: Harnessing advanced oil pouring cup leak-proof architecture and a state-of-the-art back-clamp sealing pin, this technology significantly mitigates the risk of hydraulic oil leakage, enhancing safety and performance.

3. Clamping Actuator
Replaceable Jaw Module: Featuring an optimized jaw, meticulously validated through ANSYS static analysis, this design minimizes stress concentration on the drill pipe. It supports rapid replacement, accommodating a diverse range of drill pipe specifications (φ87~φ203mm), ensuring adaptability and longevity.
Anti-Loosening Device: This device boasts a sophisticated mechanical anti-loosening mechanism, complemented by dual PLC control, which safeguards against accidental clamp loosening during operations, ensuring safety and precision.

4. Auxiliary Function Components
Shock Absorption System: Designed with an integrated shock absorption spring and guide shaft, this system effectively absorbs the vibrations of the drill string, providing robust protection to the clamp structure and enhancing durability.
Anti-Torque Frame: Expertly transmits anti-torque to the Top Drive body through a sturdy rigid connection, ensuring unparalleled operational stability and reliability during critical drilling applications.

5. Safety and Adaptability Design
Retaining Wall Support Structure: Ingeniously prevents lateral displacement while significantly boosting anti-eccentric load capacity, promoting enhanced safety and structural integrity.
Modular Interface: Seamlessly adapts to leading Top Drive models like TDS11SA, while supporting swift disassembly and assembly, facilitating unrivaled operational flexibility.
