Abstract

The invention relates to underwater steel wire rope operation equipment with releasing and withdrawing functions. The underwater steel wire rope operation equipment is characterized by comprising a main sleeve, the upper end of the main sleeve is connected with a connecting sleeve, the connecting sleeve is connected with a top joint in a sleeving manner, a mandrel is mounted in a center through hole of the main sleeve, the upper end of the mandrel is connected with a mandrel cap and sleeved with a mandrel spring, the upper end and the middle of the mandrel are provided with an upper pin slot and a lower pin slot, an upper radial spring pin and a lower radial spring pin are arranged in the middle of the main sleeve and used for matching with the upper and lower pin slots, a lower neck bush is arranged at the lower end of the main sleeve, square slots are formed in the periphery of the lower neck sleeve, elastic locking blocks are disposed in the square slots, and the rear ends of the elastic locking blocks are matched with the outer peripheral surface of the lower end of the mandrel and grooves formed in the middle-lower portion of the mandrel respectively to realize springing out or retracting of the elastic locking blocks. The underwater steel wire rope operation equipment is compact in structure and reasonable in arrangement; axial movement opportunity and distance of the mandrel can be controlled accurately to realize connection and disconnection with the underwater equipment; the equipment is simple to mount and demount, reliable in connection and convenient to use and operate.

Description

technical field [0001] The invention relates to the lowering, installation and unlocking recovery operation tool of specific parts of deep-water oil and gas equipment, in particular to the underwater steel wire rope working tool with both lowering and recovery functions, and belongs to the technical field of offshore oil recovery equipment. Background technique [0002] In the process of deep sea oil and gas exploitation, the underwater production system is an important part. In the early stage of production, due to the influence of the production process, some components cannot be lowered together with the main equipment during installation, such as the blocker inside the underwater tree, etc., which need to complete a certain process before being lowered for installation. At this time, special During the production process, if relevant tools or instruments need to be released, specific lowering tools are also required; after the production is completed, the equipment needs...
