Problems solved by technology
It can be seen that the existing processing method must assemble the ring rail beam in the reactor and adjust it to be qualified before the accurate measurement and final processing of the thickness of the backing plate can be carried out. The whole process needs to be divided into preliminary processing and finishing processing twice, resulting in The construction period is long, and the construction period of the critical path occupied by the ring crane is long, which affects the economics of the nuclear power plant

Embodiment Construction
[0045] In order to enable those skilled in the art to understand the present invention more clearly, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0046] In view of the existing technology, it is necessary to assemble the ring rail beam in the reactor and adjust it to be qualified before the thickness measurement and final processing of the adjustment backing plate can be carried out, resulting in a long construction period and a long construction period of the key path of the ring crane construction. The present invention aims to provide a construction method for measuring the backing plate of the ring-hanging track beam of the nuclear power plant. The ring rail beam is pre-assembled on the ground, and the accurate processing thickness of the backing plate is obtained through precise measurement and simulation data calculation, and the adjustment backing plate is processed once. Forming...

The invention provides a measuring and processing method for an annular rail beam adjusting base plate of a nuclear power station. The method comprises the steps that S1, an annular rail beam is pre-assembled on the ground and adjusted to meet assembly requirements; S2, elevation data of the lower surface of the annular rail beam and elevation data of the upper surface of the annular rail beam arecollected; S3, height data of the annular rail beam is calculated according to the elevation data of the lower and upper surfaces of the annular rail beam; S4, elevation data of the upper surfaces ofbrackets is collected; S5, the theoretical thickness of the adjusting base plate is calculated according to the height data of the annular rail beam and the elevation data of the upper surface of thebracket, and the adjusting base plate is processed according to the theoretical thickness. According to the measuring and processing method for the annular rail beam adjusting base plate of the nuclear power station, the adjusted base plate can be processed and formed at a time, the thickness of the adjusting base plate accurately meets the gap value requirement, and the adjusting base plate canbe inspected and qualified once during actual sling construction, so that the main line construction period is shortened, and the economical efficiency of the nuclear power station is improved.
Description
technical field [0001] The invention relates to the technical field of nuclear power construction, in particular to a method for measuring and processing ring rail beam adjustment backing plates of nuclear power plants. Background technique [0002] The nuclear power plant ring crane is installed above the reactor building of the nuclear power plant. It is a large bridge crane running on the ring rail beam. It is mainly used for hoisting large equipment such as reactors and steam generators. like figure 1 As shown, the ring rail beam 10 of the ring crane is installed on the corbel 20 of the reactor building, and an adjustment backing plate 30 is installed between the ring rail beam 10 and the corbel 20, and the ring is adjusted by accurately measuring and processing the thickness of the backing plate 30. The elevation and levelness of rail beam 10. Since the levelness and elevation requirements of the ring rail beam after installation are relatively high, and the gap betwe...
