Embodiment
[0048] A bolt loosening monitoring device includes a first sleeve 1, a second sleeve 2, an auxiliary mounting part 3 and a radio frequency system; the radio frequency system includes a radio frequency assembly 7 and two groups of metal sheets (respectively the first metal sheet 1.1 and The second metal sheet 2.2), such as Figure 1-6 As shown, the details are as follows:
[0049] Such as figure 1 As shown, the first sleeve 1 is fixedly sleeved on the head of the bolt 4, the second sleeve 2 is sleeved on the outer wall of the first sleeve 1, and the second sleeve 2 is fixed by the auxiliary mounting part 3 On the working face or pier 5, when the bolts loosen, the first sleeve 1 can rotate relative to the second sleeve 2. The shape of the first sleeve 1 and the second sleeve 2 is circular; as image 3 and Figure 5 As shown, in order to ensure the stability between the first sleeve 1 and the second sleeve 2, the outer wall of the first sleeve 1 is provided with grooves 1.2 a...

The invention discloses a bolt looseness monitoring device which comprises a first sleeve, a second sleeve and a radio frequency system. The radio frequency system comprises a radio frequency assembly and two groups of metal sheets. By arranging the radio frequency assembly, large-range, large-quantity and long-distance monitoring can be achieved, and loose bolts can be accurately positioned. The invention further discloses a bolt looseness monitoring system which comprises the RFID reader-writer, a data management system and the bolt looseness monitoring device. The RFID reader-writer is in signal connection and information interaction with the bolt looseness monitoring devices arranged on the anchor bolt along the line, and then position information of the loosened bolt is obtained. The invention further discloses a bolt looseness monitoring method, the bolt looseness monitoring system and the data management system are adopted to record the information, read and written by the RFID reader-writer, in the electronic tag, and the recorded information is compared with the information recorded in the data management system to obtain the information of the loosened bolt.
Description
technical field [0001] The invention relates to the field of bolt monitoring, in particular to a bolt loosening monitoring device, system and method. Background technique [0002] As an important fastener connection method, bolt connection is widely used in rail transit, railway bridge, construction machinery, automobile manufacturing, aerospace, wind power nuclear power and shipbuilding industries, and the fastening state of bolt connection is directly related to engineering facilities, The safety and reliability of instruments and equipment, if the bolt connection loosens or falls off due to vibration, shock, insufficient pre-tightening force, etc., it will lead to major safety accidents and huge economic losses. [0003] The problems existing in the existing bolt monitoring are: 1. Relying on manual inspection during the "skylight period" at night and carrying out inspections one by one with tools, the demand for personnel is large and the safety is not high; 2. The exist...
