Vibration monitoring apparatus

Abstract

The invention discloses a vibration monitoring apparatus, which includes a bracket, a swing arm and a damped system. The swing arm includes a swing arm ball, a swing arm rod, a counterweight and an extension rod, wherein the swing arm ball is movably connected with the bracket and can rotate random; the swing arm ball is fixedly connected with the upper end of the swing arm rod; the counterweightis arranged at the lower end of the swing arm rod; the lower end of the swing arm rod is connected with the first end of the extension rod, and the second end of the extension rod extends downward orthe first end of the extension rod is connected with the upper end of the swing arm rod and the second end of the extension rod extends upward; the damped system has damped influences on the swing armduring swinging; and the swing arm can swing in any horizontal orientations, the swing amplitude of the swing arm represents the vibration intensity of monitoring positions, and a direction of horizontal component of a swing direction of the swing arm is the direction of the horizontal component of hypocenter direction. The vibration monitoring apparatus is minaturization in shape, low in cost, convenient to operate, and easy to maintain, and can monitor the vibration intensity of the monitoring positions and the direction of the horizontal component of the hypocenter direction.

Description

technical field [0001] The invention relates to detection equipment, in particular to a vibration monitor. Background technique [0002] As small as microscopic particles such as electrons, atoms, and molecules, as large as electronic products and equipment, the earth, planets, and the universe, people are monitoring their vibrations through various equipment and instruments to obtain a large number of research data, and their research results have been widely used. in our daily work. Now, people generally attach the vibration sensor of the vibration monitoring device to the mechanical equipment to monitor the vibration of the mechanical equipment; or place the vibration monitoring device on the ground to directly monitor the vibration of the ground. For the monitoring of large vibrations, ordinary vibration monitoring equipment can already meet the requirements of use, but for finishing equipment with weak vibrations, vibrations of the ground, etc., the monitoring data wil...

AI Technical Summary

Problems solved by technology

For the monitoring of large vibrations, ordinary vibration monitoring equipment can already meet the requirements of use, but for finishing equipment with weak vibrations, vibrations of the ground, etc., the monitoring data will be distorted

For example, the seismograph invented by Zhang Heng more than 1900 years ago, and the seismic observation network currently used by the country, etc., have extremely high precision in vibration monitoring, can detect weak vibration signals, and can be used to monitor vibrations of finishing equipment and the ground, etc. However, they are all large-scale equipment with complex structures and require special maintenance, so they are not suitable for ordinary enterprises, institutions, and individuals.
