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.

Embodiment Construction
[0028] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.
[0029] The carrier of the present invention includes a lifting mechanism, a horizontal moving mechanism and a wire saw turning mechanism installed on the wall. The lifting mechanism includes a segmented base truss structure, a wall locking mechanism that locks and installs the segmented base truss structure and the wall, a wire saw machine support frame, a lifting motor, a gear tooth set on the truss structure bar, double-head hydraulic cylinder, locking block; the wall locking mechanism can quickly cooperate with the pre-drilled through holes in the wall to lock the segmented base truss structure. According to the height of the wall, the segmented truss The number of segments of the structure can be changed accordingly. The rack and pinion are driven by the lifting motor, and the frame of the wire saw machine starts to rise and fall. ...

The invention provides a diamond wire saw machine carrier for nuclear facility dismantling. The lifting structure includes a wall locking structure, a segmented base truss structure, a lifting motor and a gear rack, and the horizontal moving mechanism includes an I-beam guide rail. , horizontal screw and moving motor, etc. The overturning structure of the wire saw machine includes a turning mechanism, a horizontal locking mechanism and a vertical locking mechanism. The wall locking mechanism quickly installs and locks the segmented truss structure to the wall. The lifting motor drives the gear rack to drive the support frame of the wire saw machine to move up and down along the lifting guide rail. The support frame carries the horizontal moving mechanism and the wire saw. Machine turning mechanism. After reaching the predetermined height, the horizontal movement motor drives the turning mechanism of the wire saw machine to move horizontally along the I-beam guide rail through the slider to reach the predetermined position. After reaching the vertical position, the vertical locking block cooperates with the locking groove on the bottom plate of the diamond wire saw machine to complete the positioning and locking during vertical cutting and removal. The present invention can efficiently dismantle the whole decommissioned nuclear facility wall.
Description
technical field [0001] The invention relates to a diamond wire saw machine carrier used for dismantling nuclear facilities, belonging to the technical field of nuclear engineering. Background technique [0002] Due to its light structure, wide range of operating objects, low environmental pollution, and strong adaptability to the operating location and the shape of the operating object, the diamond wire saw is used in special fields such as submarine equipment maintenance and dismantling of abandoned nuclear equipment. For the decommissioning of decommissioned nuclear facilities, the structure and shape of the nuclear power plant are complex. Due to the huge volume of the containment, the diamond wire saw machine has to be frequently moved to different heights and different horizontal positions for cutting and demolition operations. How to install the wire saw machine on the outer wall of the containment It is also the current technical problem. Nuclear power plant faciliti...
