Description

Technical Field

[0001] This utility model relates to the field of vibration monitoring technology, specifically to a vibration monitoring device for electromechanical equipment. Background Technology

[0002] Industries such as machinery manufacturing have a large number of electromechanical equipment such as motors, pumps, fans, compressors, and gearboxes operating continuously. In existing technologies, vibration monitoring instruments are typically used to monitor changes in physical quantities such as vibration amplitude, frequency, and direction. For critical equipment, online monitoring systems are generally employed. The advantage of this system is that the equipment is under 24-hour monitoring, utilizing computer storage to record operating parameters including vibration acceleration, velocity, and displacement. It also provides timely alarms and collects as much fault information as possible once early signs of malfunction appear. However, the connection between the probes of existing monitoring instruments used for continuous vibration monitoring of electromechanical equipment is mostly achieved by directly fixing them to the equipment housing or base with bolts. Vibration of the equipment can easily cause these bolts to loosen, resulting in poor installation stability of the vibration monitoring device and affecting the accuracy of the vibration monitoring data. Therefore, this case study was developed to address these issues. Utility Model Content

A limit stop 10 is provided on the side of the mounting base 4, and a limit locking component 11 is provided on the limit stop 10. A positioning blind hole 12 is opened on the side wall of the square shell-type flange cover plate 8 corresponding to the position of the limit locking component 11. One end of the limit locking component 11 is inserted into the positioning blind hole 12. A mounting base 4 is welded onto an existing electrical equipment housing or base. The monitoring probe 2 is inserted into the square shell-type flange cover plate 8, and the square shell-type flange cover plate 8 is fastened to the mounting base 4. The monitoring probe 2 is inserted into the square flange groove 6 on the mounting base 4 and fixed by fastening bolts 9, so that the end of the monitoring probe 2 is inserted into the mounting groove 5 and fixed to the mounting base 4 by studs 14. The side of the square shell flange cover 8 is further limited and locked by the limiting locking component 11 on the limiting block 10. The limiting locking component 11 and the fastening bolts 9 respectively limit and lock the square shell flange cover 8 in the horizontal and vertical directions, thereby effectively ensuring the tight fit between the monitoring probe 2 and the mounting base 4, improving the accuracy of data monitoring, even if If the fastening bolt 9 becomes loose under vibration, the limiting and locking component 11 can also limit and lock the square shell flange cover plate 8 and the monitoring probe 2 in the horizontal direction, thereby fully ensuring the reliability of the monitoring data of the vibration monitor 1. The installation is simple and the disassembly and maintenance are relatively convenient. It should be noted that the vibration monitor 1 is a commonly used device in this field. The structure and model of the monitoring probe 2 can be referenced from the MODEL-2502-01 / 2502-02 / 2502-03 vibration meter probe of Showa SHOWA Corporation of Japan.

The locking component includes a locking pin 1104, which is slidably inserted into the guide seat 1102. One end of the locking pin 1104 is fixedly provided with a threaded section 1105. Rotatingly engaging with the threaded seat 1101, one end of the threaded section 1105 is provided with an internal hexagon nut 1106. One end of the aforementioned fixing hole 1103 is provided with a countersunk groove 1107 corresponding to the position of the internal hexagon nut 1106. After the square shell flange cover plate 8 is installed in place, the locking pin 1104 is inserted into the fixing hole 1103 and passes through the threaded seat 1101 and the guide seat 1102 in sequence. The nut is rotated so that the threaded section 1105 moves along the threaded seat 1101, and the locking pin 1104 is further inserted into the positioning blind hole 12 on the side of the square shell flange cover plate 8 to further limit and lock the square shell flange cover plate 8.
