Problems solved by technology

According to the ISO 13628-8 standard, the driving torque required by the Class I-IV interface has a large distribution range. If the output torque is changed only by adjusting the flow rate of the hydraulic motor, the Class I-IV level in the ISO 13628-8 interface standard cannot be provided. Therefore, it is necessary to study a transmission scheme that can increase the torque output range, so that emergency maintenance tools can complete torque adjustment underwater

Abstract

The invention provides a torque tool capable of switching torque gears for an ROV. The torque tool structurally comprises a torque tool connector, a locking mechanism and a hydraulic driving mechanism. The hydraulic driving mechanism provides torque for the torque tool connector and conducts rotating operation on a standard rotating butt joint connector on underwater production equipment. The hydraulic driving mechanism adopts two switchable transmission routes so as to obtain a larger torque output range. The torque tool connector can be in butt joint with a rotary butt joint connector meeting the Class IV level in the ISO 136288 connector standard. The locking mechanism can lock the rotary butt joint connector, and connection stability in the rotating process is guaranteed. The torque tool capable of switching the torque gears for the ROV is convenient, quick, stable and reliable to operate.

Description

technical field [0001] The invention relates to a torque tool for an ROV with switchable torque gears, belonging to the field of offshore oil engineering. Background technique [0002] According to the ISO 13628-8 standard, important equipment such as Christmas trees, manifolds, and subsea control modules in the subsea production system need to use standard rotary docking interfaces for operation. The standard stipulates that the rotary docking interface is divided into I-VII grades, and most of the underwater production equipment interfaces are I-IV grades. Therefore, the underwater torque tool that can operate the I-IV grade rotary docking interface is one of the important tools for underwater operations. . [0003] The ROV torque tool with switchable torque gears designed by the present invention can be clamped by a Remote Operated Vehicle, and can provide torques of different sizes to operate multiple levels of rotary docking interfaces to realize underwater production ...
