④, judging whether the high-strength bolt reaches the screwing depth required by the specification or not according to the data displayed on the screen of the spectrum reader, wherein the relative position relationship between the spectral band and the high-strength bolt is fixed because different colors on the spectral band correspond to different positions, so the equipment software can calculate the specific value of the depth through direct data conversion of different colors;
⑤ the designer can calculate according to the depth value to check whether the stress meets the original design requirement, if not, the structure is adjusted and the high-strength bolt is screwed by the spanner, then the spectral band on the high-strength bolt is read by the spectrum reader, and whether the requirement is met is judged according to the displayed data;
⑥ repeating the above steps until the high-strength bolt reaches the screwing depth required by the specification, screwing the cross pin, and then the subsequent inspector can unscrew the cross pin to perform sampling inspection or full inspection operation, and repeating the above inspection steps.
The working principle is as follows:
1. the high-strength bolt containing the spectral band consists of a high-strength bolt for a bolt ball grid frame and the spectral band sprayed or stuck on the high-strength bolt. The spectral band is pasted in the processing factory in the high strength bolt recess back region, makes it effectively adhere to with high strength bolt. The spectral band is marked, positions are distinguished by different colors, the end portion is a red area, the downward direction is sequentially orange, yellow and green, the position relation of each area and the size of the end portion of the bolt are relatively fixed, and spectral band data are equivalent to position targets.
2. The sleeve with the observation hole consists of a sleeve body and a pin. The structure is a hexagonal sleeve for a net rack, which is originally provided with a small hole with a diameter for screwing in a straight stud; now, the opposite side is opened with a 10mm diameter viewing hole through which the device can read data information. The hole is also provided with threads, and the high-strength bolt is closed by a cross screw after being screwed in.
3. The spectrum reading instrument is powered by a lithium battery and is operated by a hand. The light waves are emitted through the diode, pass through the observation hole in the sleeve, the spectrum scale on the high-strength bolt is read, the screwing depth is directly output on the screen through a program, and whether the requirements are met is judged.
The invention relates to a reading structure for the screwing depth of a high-strength bolt of a bolt net rack and a measuring method thereof, and safety performance is improved.
