Abstract

The invention belongs to the technical field of nuclear power station operation and maintenance, and particularly relates to a bolt group pre-tightening data measuring and wireless collecting device and system and using methods of the device and the system. According to the technical scheme, the system comprises a data acquisition system and a wireless transmission system, wherein the data acquisition system comprises a measuring meter, a data line and an acquisition emitter, the measuring meter is connected to a to-be-measured bolt and is connected with the acquisition emitter through the data line, the wireless transmission system comprises a data receiver and a notebook computer, the data receiver is connected with the acquisition transmitter of the data acquisition system through a carrier signal, a wireless receiving component is arranged in the data receiver, and the data receiver is inserted into the notebook computer through the USB plug of the data receiver. According to the invention, measurement values on a depth dial indicator can be collected and are collected into a computer system in a wireless sending and receiving mode, the previous manual reading and recording operation mode is changed, synchronous collection of multiple groups of data can be realized, the work efficiency is improved, and human errors are avoided.

Description

technical field [0001] The invention belongs to the technical field of operation and maintenance of nuclear power plants, and in particular relates to a device, system and method for measuring and wirelessly collecting bolt group preload data. Background technique [0002] The nuclear reactor pressure vessel adopts the flange bolt group fastening structure, that is, the cylinder and the top cover of the pressure vessel are connected by the bolt group flange connection structure, such as figure 1 shown. It is necessary to measure the elongation of these bolts to ensure the pre-tightening force when the refueling is overhauled and the cover is closed. Due to the large number of bolts, the workload of measuring the pre-tightening force is relatively large. The traditional nuclear reactor bolt pre-tightening data measurement adopts manual measurement, manual recording, and manual data analysis. It uses a digital depth dial gauge to manually measure the elongation of each bolt, ...
