Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of monitoring devices, in particular to a monitoring device based on coupled vibration. BACKGROUND

[0002] Coupled vibration refers to a vibration system composed of several vibration systems, and the vibration modes of the vibration systems are not independent, but are affected by energy transfer from one mode to other modes. In the railway environment, when the motor train is running, it will produce coupled vibration to the surrounding buildings. Therefore, a monitoring device is needed to monitor the coupled vibration.

[0003] However, for the current coupled vibration monitoring device, most of them are monitored in real time by electronic devices, so that the monitoring personnel can only monitor the vibration by observing the numerical changes, which makes it inconvenient for them to intuitively understand the ups and downs of the vibration, and thus inconvenient to use. In addition, due to the small size of the electronic device, the contact range with the ground is small, which makes it difficult to monitor slight vibration, thus making it difficult to monitor the coupled vibration throughout, and thus making it difficult to use.

[0040] like Figure 10As shown, the mounting bracket 301 has a disc-shaped structure, and a rectangular protrusion is provided on the outer wall of the mounting bracket 301.

Then, the adjusting block 104 is rotated, so that it is adjusted on the auxiliary rod 103 through the thread while rotating, thereby facilitating the control of the drive ring 202 for adjustment. During the adjustment process, the telescopic frame 201 is controlled through the connecting plate 203, so that the telescopic frame 201 extends out of the adjusting groove 102, thereby increasing the contact range between the device and the ground and increasing the monitoring of vibration. Then, by rotating the locking rod 204, it is inserted into the ground under the action of the thread, thereby facilitating the overall stability of the device. During use, when the train enters the station, the coupled vibration generated by the train on the surrounding buildings gradually increases. When the surrounding buildings vibrate, the device on the base frame... Under the action of 101 and the telescopic frame 201, the vibration is synchronous with the building, so that when the vibration frame 401 is subjected to vibration, the balance force at its upper and lower ends is affected accordingly, and the balance force is broken and vibration occurs. At the same time, under the action of the mounting block 402, the shaking block 403 shakes, making it easier to display the vibration, so that the monitoring personnel can have a direct understanding. When the vibration frame 401 vibrates, the top pull rod 404 drives the monitoring block 304 to move up and down, so that it slides in the telescopic groove 303. At the same time, the monitoring block 304 monitors the coupled vibration, making it easy to use. When the train leaves the station, its impact on the surroundings decreases, so the vibration of the device also decreases, so that the vibration frame 401 returns to balance under the action of the balance spring, thus making it easy for the device to return to its initial state.
