Product Description

The Top Drive Back-Up Clamp, an indispensable component of the Top Drive Drilling System (TDS), excels in optimizing the automatic unscrewing and screwing of drill pipes during drilling operations. Its primary role is to securely hold the drill pipe using hydraulically operated jaws, working in perfect harmony with the Top Drive. This synergy ensures seamless and secure make-up and break-out processes, dramatically boosting drilling efficiency while minimizing the hazards associated with manual intervention.

The core components and functions:
1. Clamp body structure
Dual-cylinder clamp design: This innovative, hydraulically powered dual-cylinder system synchronously drives the jaws, ensuring a balanced and robust clamping of the drill pipe. It offers a superior and more reliable performance than conventional single-sided clamping techniques.
Floating pin mechanism: Featuring a spring-supported floating pin, this mechanism automatically adjusts for displacement variances when the drill pipe threads are joined, enhancing the precision of make-up and break-out tasks.

2. Hydraulic drive system
Hydraulic Cylinder and Piston: Experience the precision and power of our hydraulic system. The solenoid valve expertly directs the oil circuit, seamlessly guiding the piston to slide. This motion, in turn, extends and retracts the jaw support, flawlessly executing the clamping and release actions with unparalleled efficiency.
Sealing Technology: Employing cutting-edge oil pouring cup leak-proof structures and back-clamp sealing pins, our system significantly minimizes the risk of hydraulic oil leakage. This advanced sealing technology ensures that operational efficiency is maintained, safeguarding against potential leaks.

3. Clamping Actuator
Replaceable Jaw Module: Featuring an optimized jaw design, verified through rigorous ANSYS static analysis, our module minimizes stress concentrations on drill pipes. The design allows for swift and effortless replacement, accommodating drill pipes of various specifications (φ87~φ203mm), thus enhancing versatility and reducing downtime.
Anti-Loosening Device: Our clamp is fortified with a mechanical anti-loosening mechanism and dual PLC control. This sophisticated design helps prevent accidental loosening during operations, ensuring unwavering reliability and safety.

4. Auxiliary Function Components
Shock Absorption System: Built with an integrated shock absorption spring and guide shaft, this system effectively mitigates drill string vibrations. It not only protects the clamp structure from potential damage but also enhances operational longevity and performance.
Anti-Torque Frame: This robust frame efficiently channels anti-torque to the Top Drive body through a rigid connection, ensuring stable and secure operational conditions.

5. Safety and Adaptability Design
Retaining Wall Support Structure: Engineered to prevent lateral displacement, this structure enhances the anti-eccentric load capacity, providing robust support and stability under challenging conditions.
Modular Interface: Designed to seamlessly integrate with mainstream Top Drive models like the TDS11SA, this interface supports rapid disassembly and assembly, allowing for streamlined operations and adaptability.
