Problems solved by technology

In view of the complex working characteristics of offshore devices and equipment, the workload in dismantling operations is huge, the operation process is intricate and cumbersome, the area is widely affected, and the dismantling is limited by environmental protection, safety, and economic factors, making deep-water diamond wire saws During the operation process, due to the constant change of tension force, the life of the beaded rope is seriously reduced, and the driving force of the cutting motor cannot be effectively applied to the beaded rope, so that the beaded rope often slips with the increase of cutting force. Because there is no overload protection and Vibration reduction facilities, a series of problems such as broken ropes, drive damage, and operator injuries often occur during operation
[0003] Chinese patent application (publication number CN104858495A) discloses a wire saw machine for cutting deep-sea pipelines. The feed drive of the wire saw machine uses gears to drive the lead screw to feed, but the feed drive has no overload protection, and complex structures can be cut underwater. Very easy to damage the drive mechanism
In addition, the beaded rope is tensioned by the nut screw method, which makes the beaded rope too rigid, which makes it difficult to reduce the vibration during the operation of the beaded rope, and is easy to break the rope. Since the ROV can carry less than 20kg, this machine does not have deep water Compatibility of job with ROV operation
[0004] Chinese patent application (publication number CN203843300A) discloses an underwater diamond wire saw machine. The wire saw machine is equipped with an underwater hydraulic control system and a power system, which avoids the pipeline between the wire saw machine body and the hydraulic station when operating in deep water. loss and secondary design, but the machine body is large in size and heavy in weight, which is not conducive to the carrying and operation of ROV, which limits the flexibility and application range of underwater operations, and adopts the three-wheel arrangement, the cutting pipe diameter range is narrow, and the beading The rigidity of the rope is large, which affects the life of the beaded rope

Abstract

The invention provides a deepwater diamond wire sawing machine which is majorly composed of a cutting drive mechanism, a feeding drive mechanism, a feeding speed regulating mechanism, a string bead wire tensioning mechanism and clamping mechanisms, and used for completing cutting repair of underwater structures. The feeding speed regulating mechanism is adopted for the deepwater diamond wire sawing machine, the feeding speed can be regulated along with the change of tension of a string bead wire in the operating process, and the service life of the string bead wire, the cutting efficiency of the machine and the reliability of cutting operation are effectively guaranteed. The feeding drive mechanism can promote transmission separation of a feeding motor and a lead screw, so that overload protection for the feeding drive mechanism is achieved; and meanwhile, under the condition that the machine does not have power, a handle can be rotated for feeding, and integrally automatic and manual drive feeding is achieved. A strong spring, a nut and a screw are adopted for tensioning of the string bead wire tensioning mechanism, and vibration of the string bead wire in the cutting process can be effectively reduced accordingly. The deepwater diamond wire sawing machine is provided with buoyancy materials and a deepwater valve box and suitable for deepwater environment operation.

Description

technical field [0001] The invention relates to a deep-water diamond wire saw machine, which belongs to the technical field of marine engineering. Background technique [0002] Deep water diamond wire saw machine, with the flexibility of its beaded rope and the rigidity of diamond, can work on a wide range of objects, and is not limited by the working environment and the shape of the cutting object. It is used in special fields such as the maintenance of submarine components and the dismantling of nuclear power plants. at work. The deep water wire saw machine is usually carried by ROV (Underwater Cable Robot), and assists in the operation for underwater operations. In view of the complex working characteristics of offshore devices and equipment, the workload in dismantling operations is huge, the operation process is intricate and cumbersome, the area is widely affected, and the dismantling is limited by environmental protection, safety, and economic factors, making deep-wa...
