Description

Technical Field

[0001] The invention relates to the field of cutting technology, and in particular to a multifunctional remote cutting device. Background Art

[0002] In the field of nuclear facility decommissioning, there is a great demand for cutting thick-walled cylindrical components such as pressure vessels, in-core components, and large pipelines. Since these components contain radioactive contamination, the risk of radiation exposure to operators is high, and remote automated cutting needs to be achieved. However, the wall thickness and overall dimensions of the components are large, and the cutting difficulty and work intensity of personnel are very high. Therefore, it is necessary to develop a remote cutting device for thick-walled cylindrical components. At the same time, there is a large demand for disassembly of thin-walled parts of various shapes such as brackets, ribs, and shells, which are used in nuclear facility decommissioning, general industrial maintenance, and equipment dismantling. However, this type of cutting requires high adaptability and flexibility of the tool, and it is necessary to use a robotic arm carrying a tool head for cutting for different objects. Therefore, it is necessary to develop a multifunctional remote cutting device that can meet both the cutting of thick-walled components with high radioactivity levels and the cutting of thin-walled components with various complex structures.

[0003] At present, large thick-walled components in the general industrial field do not involve radioactive pollution, and the requirements for the generation of secondary waste and remote automated operation are very low. The installation and fixation requirements of the components are not high. Flame cutting, plasma cutting, laser thermal cutting and other methods are often used to perform external cutting on large thick-walled components. However, these thermal cutting methods are prone to produce radioactive aerosols, causing environmental pollution, and personnel are prone to inhaling a large amount of them into the body when operating at close range, causing internal irradiation. At the same time, large components are very heavy, and it is difficult to install and lift the objects to be cut using external cutting methods. In addition, when dismantling thin-walled components, the objects to be cut are of various types and complex structures, requiring the use of highly adaptable cutting actuators and the use of a variety of tool heads to meet different functional requirements such as clamping, sawing, milling, drilling, shearing, thermal cutting, and abrasive water jet cutting. However, there is currently a lack of such multifunctional remote cutting devices. Summary of the invention

[0004] The present invention aims to solve the deficiencies of the prior art and to provide a multifunctional remote cutting device. By adopting this solution, the cutting of large thick-walled cylindrical components and thin-walled components of any shape can be achieved, and at the same time a practical device is provided for the decommissioning of nuclear facilities and the dismantling of similar facilities and equipment.

[0005] The present invention is achieved through the following technical solutions:

The various motion mechanisms of the above-mentioned three-coordinate motion system realize the position detection of the moving parts through grating rulers, wire displacement sensors, etc. The internal support frame, workbench, and mobile trolley can be used separately or in combination to realize the installation and cutting of various containers.

[0014] The above scheme aims to achieve: solving the problem of remote cutting of thick-walled containers and similar components containing radioactive contamination, and solving the problem of remote cutting of thin-walled components of arbitrary shapes. The present invention can realize the cutting and dismantling of metal components containing radioactive contamination, provide means for the dismantling of large radioactive contaminated components, provide conditions for the treatment and transportation of radioactive metal waste, and can be used for the decommissioning of various reactors, the dismantling of non-nuclear facilities and the dismantling of items in other dangerous places, and has important engineering application value.
