Description

TECHNICAL FIELD

[0001] The utility model relates to vibration monitoring technical field especially relates to a vibration monitoring device. BACKGROUND

[0002] In the modern industrial production system, the shaft body as the key transmission component of various mechanical equipment is widely used in motor, engine, fan, pump and many other equipment. The stable operation of the shaft body is directly related to the performance, reliability and service life of the whole mechanical equipment. However, due to the influence of various factors such as load change, component wear, installation deviation, etc., vibration will inevitably occur during the operation of the shaft body. Real-time and accurate monitoring of shaft body vibration can timely find potential equipment fault hidden danger, take maintenance measures in advance, avoid production stagnation, product quality decline and safety accidents caused by equipment sudden failure and other serious consequences, so the shaft body vibration monitoring device plays a vital role in industrial production.

[0003] However, the current mainstream shaft body vibration monitoring device on the market has obvious technical shortcomings. Such devices can only monitor the vibration of shaft bodies with specific outer diameter sizes in design and structure. In actual industrial application scenarios, the specifications of shaft bodies are extremely diverse, and their outer diameter sizes span greatly. For example, small motors may be used to drive cooling fans for electronic products, and their shaft body outer diameters may only be a few millimeters. Large industrial motors are used to drive heavy mechanical equipment, and their shaft body outer diameters can reach tens of centimeters or even larger. The shaft bodies equipped by mechanical equipment in different industries and for different purposes have different sizes. The existing vibration monitoring devices that can only adapt to shaft bodies with fixed outer diameters are not suitable for such a wide range of shaft body specifications. When enterprises need to monitor the vibration of shaft bodies with different outer diameters, they have to frequently replace different types of monitoring devices, which not only greatly increases the cost of equipment procurement, but also makes equipment maintenance and management extremely complex. Moreover, in some temporary emergency monitoring scenarios or after equipment upgrading and transformation, the existing monitoring devices often cannot be used in time due to the inadaptability of the new shaft body, resulting in ineffective monitoring of shaft body vibration and severely restricting the application range of the vibration monitoring device. Therefore, it is urgent to improve it. UTILITY MODEL CONTENTS

Through the threaded transmission cooperation between the external threads on the monitoring column 13 and the threads of the sleeve 11, the monitoring column 13 moves towards the surface of the shaft, thereby moving the monitoring ball 15 arranged on the monitoring column 13 towards the surface of the shaft, until the monitoring ball 15 fits the surface of the shaft. Then the shaft is rotated. If the shaft vibrates, the monitoring ball 15 in contact with the shaft vibrates on the monitoring column 13, so that the monitoring spring 16 in contact with the monitoring ball 15 frequently changes the vibration sensor 17, thereby realizing the monitoring of the vibration of the shaft.

[0074] When it is necessary to monitor the vibration of different parts of the shaft to be monitored, the positioning mechanism is started through the control device 2, so as to adjust the monitoring position of the monitoring mechanism, thereby realizing the vibration monitoring of different parts of the shaft.
