A high-efficiency variable-direction diamond wire saw machine for nuclear facility dismantling

Abstract

The invention provides a high-efficiency variable-direction diamond wire saw machine for dismantling nuclear facilities, including a cutting mechanism, an auxiliary wheel train structure, a hydraulic tensioning mechanism, a reverse screw screw feeding mechanism, a positioning wheel mechanism, and a V-shaped frame The feed mechanism, auxiliary mechanism and direction changing mechanism can be rotated; the power motor on the cutting mechanism drives the cutting wheel to rotate, and the cutting wheel transmits power to the diamond beaded rope on it. The beaded rope reaches the reverse thread screw feed mechanism and the V-shaped frame rotatable feed mechanism through the auxiliary wheel train structure and the hydraulic tensioning mechanism. The auxiliary wheel on the auxiliary wheel train mechanism guides the movement of the beaded rope, and transmits power to the auxiliary wheel train support, and automatically adjusts the posture of the support and the wheel train through rolling bearings. In the small-scale tensioning process of the beaded rope processing process, the expansion and contraction of the expansion rod of the tensioning hydraulic cylinder drives the slider of the tensioning wheel to move along the guide rail on the tensioning support plate, and then transmits the motion to the tensioning wheel to complete the alignment. Tensioning task for diamond beaded rope.

Description

technical field [0001] The invention relates to a high-efficiency variable-direction diamond wire saw machine used for dismantling nuclear facilities, and belongs to the technical field of nuclear engineering. Background technique [0002] Diamond wire saw machine is used in special fields such as subsea equipment maintenance and dismantling of abandoned nuclear equipment due to its light structure, wide range of operating objects, low environmental pollution, and strong adaptability to the operating site and the shape of the operating object. Due to the complex structure and shape of nuclear equipment, the containment of nuclear equipment is bulky and has serious nuclear radiation. When decommissioning and dismantling it, it needs to be divided into many regular block structures and gradually dismantled. It is often necessary to make the diamond wire saw machine stand alone at high altitude. When the diamond particles on the beaded rope are severely worn or the dismantling ...

Problems solved by technology

Due to the complex structure and shape of nuclear equipment, the containment of nuclear equipment is bulky and has serious nuclear radiation. When decommissioning and dismantling it, it needs to be divided into many regular block structures and gradually dismantled. It is often necessary to make the diamond wire saw machine stand alone at high altitude. When the diamond particles on the beaded rope are severely worn or the dismantling of waste equipment in different directions needs to be completed, the staff needs to perform multiple complicated and long-term replacements, which will cause cumbersome work and radiation exposure to the operators.
