Problems solved by technology

However, the feed mechanism and cutting mechanism of the wire saw machine are located perpendicular to the structure, which makes the overall volume of the wire saw machine too large, which limits the flexibility and application range of underwater operations.
In addition, if a beaded rope fails to complete the cutting task during the cutting process, the beaded rope cannot be replaced in time

Abstract

The invention provides a modular underwater vertical diamond wire saw. The modular underwater vertical diamond wire saw is suitable for completing cutting work of underwater large-diameter structuralobjects, and can replace cutting modules underwater and keep notch positions unchanged. The saw is mainly composed of an overall frame 1, a feeding device 2, a clamping and fixing device 3, a cuttingdevice 4, a string bead wire tensioning device 5 and the like. During use, the modular underwater vertical diamond wire saw enclasps a to-be-cut structural object 6 in a vertical state. The wire saw is relatively fixed to the structural object by the clamping device, and the cutting device and the feeding device jointly act to achieve the cutting work. The underwater vertical diamond wire saw is stable and reliable in working state and small in occupied space, string bead wires can be replaced underwater through an ROV, operation is easy and convenient, implementation is easy, and the whole working process is achieved through hydraulic control.

Description

technical field [0001] The invention relates to a modular underwater vertical diamond wire saw machine, which belongs to the technical field of marine engineering. Background technique [0002] With the growth of the world's population and the scarcity of onshore oil and gas resources, various resources in the ocean have received extensive attention. In our country, marine resources have become an important source of resources in our country. Along with the development of oil and gas resources, a variety of offshore equipment emerged as the times require. Offshore oil exploitation has a long history. The oil and gas resources in some sea areas are gradually depleted, and the oil and gas exploration platforms in these sea areas are gradually abandoned. The platforms still under mining have also caused safety problems such as pipeline corrosion and leakage due to disrepair. Therefore, the problem facing our country today is how to repair or dismantle marine equipment. [0...
