Problems solved by technology

[0003] The existing product usage methods are mainly as follows: when there is a need to use a torque tool to rotate underwater equipment, the ROV operator needs to select the correct sleeve size and appropriate torque to ensure that the output torque of the torque tool will not exceed the maximum bearing capacity of the underwater equipment. If the torque used exceeds the limit of the equipment, the equipment may be damaged or fail, and it is very difficult and expensive to recover these subsea equipment for repair or replaceme

Abstract

The invention relates to an external connecting tool for an ROV and aims to provide a torque tool. The torque tool comprises a torque driving unit, an insertion opening unit and a locking bolt unit. According to the torque tool, a method that a torque multiplier is used for torque transmission and amplification is provided, the output torque is increased, the operation time is shortened, the size of a product is reduced, and the transmission efficiency of the product is improved; the design that a telescopic sleeve insertion opening is used is provided, self-adaptive butt joint of a plurality of stages of ports can be achieved without manual replacement of the insertion opening, and the usability of the product is improved; and a sliding block is used for converting axial movement into radial movement, so that the contact area is enlarged, the movement precision is improved, and the stress reliability and accuracy are guaranteed when a locking bolt finger moves.

Description

technical field [0001] The invention relates to the field of ROV external tools, in particular to a torque tool. Background technique [0002] Torque Tool (Torque Tool), as a ROV external tool, is mainly used to switch underwater ball valves. It can be mounted on ROV to provide different levels of torque for ball valve switching. It is widely used in deepwater oil and gas field development. Torque tools are driven by torque. Unit, socket unit, and latch unit, which provide forward and reverse torque for switching ball valves in actual use. [0003] The existing product usage methods are mainly as follows: when there is a need to use a torque tool to rotate underwater equipment, the ROV operator needs to select the correct sleeve size and appropriate torque to ensure that the output torque of the torque tool will not exceed the maximum bearing capacity of the underwater equipment. If the torque used exceeds the limit of the equipment, the equipment may be damaged or fail, an...
