Posture-adjustable multifunctional ROV torque wrench

Abstract

The invention provides a posture-adjustable multifunctional ROV torque wrench. The posture-adjustable multifunctional ROV torque wrench comprises a torque wrench interface, a locking device, a hydraulic driving mechanism, a torque switching mechanism, a guide base and a torque wrench control monitoring system. Torque is provided by a hydraulic motor, an appropriate torque gear is switched by the torque switching mechanism, and the torque is amplified by a torque amplifier and then transmitted to the torque wrench interface. The torque switching mechanism can switch the gear of the output torque, and the torque gear can be displayed by an indicating needle. The torque wrench interface can be in but connection with a rotary butt joint interface meeting the Class I-IV grade in SO 13628-8 interface standards, the locking device can lock the rotary butt joint interface, and connection stability in the rotating process is ensured. The guide base can be mounted on an ROV and finely adjusts the posture of the torque wrench. The torque wrench control monitoring system can control the torque wrench by controlling the actions of the hydraulic cylinder and the hydraulic motor, and feeds the operation state back to a control interface in real time. The posture-adjustable multifunctional ROV torque wrench is convenient and fast to operate, stable and reliable.

Description

technical field [0001] The invention relates to a wrench structure, in particular to a multi-function ROV torque wrench with adjustable posture, which belongs to the field of offshore oil engineering. Background technique [0002] Subsea tree / manifold valves are remotely controlled by hydraulic actuators. When the hydraulic or control system fails, the valve will lose control, which will affect the normal operation of the entire subsea production system. Therefore, it is necessary to solve this problem Multifunctional ROV with torque wrench for detailed design and research. The position-adjustable multifunctional ROV torque wrench designed by the present invention can be mounted on a remote operated unmanned submersible (Remote Operated Vehicle) to provide torques of different sizes to operate multiple levels of rotary docking interfaces to realize underwater Christmas trees. The local emergency shutdown of manifold valves effectively solves the problem of failure of remote...

AI Technical Summary

Problems solved by technology

[0004] The original torque wrench to adjust the torque depends entirely on adjusting the flow of the hydraulic motor to change the output torque, which cannot provide the maximum design torque of Class I–IV in the ISO 13628-8 interface standard
