Diamond wire sawing machine carrying tool for nuclear facility dismantling

Abstract

The invention provides a diamond wire sawing machine carrying tool for nuclear facility dismantling. A lifting structure comprises a wall locking structure, a sectional type base body truss structure, a lifting motor and a gear rack; a horizontal moving mechanism comprises an I-shaped steel guide rail, a horizontal lead screw, a moving motor and the like; a wire sawing machine turnover structure comprises a turnover mechanism, a horizontal locking mechanism and a vertical locking mechanism; and the sectional type truss structure is rapidly installed and locked to a wall through the wall locking mechanism, the lifting motor drives the gear rack to drive a wire sawing machine supporting frame to move up and down along a lifting guide rail, and the supporting frame bears the horizontal moving mechanism and the wire sawing machine turnover structure. After a preset height is reached, a horizontal moving motor drives the wire sawing machine turnover structure to horizontally move along the I-shaped steel guide rail through a sliding block to reach a preset position. After the vertical position is reached, a vertical locking block is matched with a locking groove in a bottom plate of a diamond wire sawing machine, and positioning and locking during cutting and dismantling in the vertical direction are completed. The whole decommissioning nuclear facility wall can be efficiently dismantled by the diamond wire sawing machine carrying tool.

Description

technical field [0001] The invention relates to a diamond wire saw machine carrier 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. For the demolition of decommissioned nuclear facilities, the structure of nuclear power plants is complex. Due to the huge volume of the containment, the diamond wire saw has to be frequently moved to different heights and different horizontal positions for cutting and dismantling operations. How to install the wire saw on the outer wall of the containment It is also a current technical problem. Nuclear power plant facilities are accompanied by strong radiation...

Problems solved by technology

For the demolition of decommissioned nuclear facilities, the structure of nuclear power plants is complex. Due to the huge volume of the containment, the diamond wire saw has to be frequently moved to different heights and different horizontal positions for cutting and dismantling operations. How to install the wire saw on the outer wall of the containment It is also the current technical problem

Nuclear power plant facilities are accompanied by strong radiation. It is necessary to consider cutting the wall into multiple regular blocks and dismantling them one by one to avoid excessive radiation. The workload is huge. To complete block cutting, construction personnel need to work at heights and artificially flip diamonds There are a series of problems such as frequent operation, long construction time and the risk of radiation damage when the wire saw machine changes direction.
