[0001] The invention relates to the field of rail transportation, and in particular to a simple monitoring device and a monitoring method for a steel spring vibration isolator. Background Art

[0002] With the development of society and the progress of science and technology, major cities pay more and more attention to the development of urban rail transit. Urban rail transit construction, especially underground railway construction, has also been greatly developed. In order to reduce the interference to the upper or surrounding properties and residents of rail transit, setting up steel spring floating slab roadbed in special sections is an important vibration isolation measure in subway design.

[0003] Steel spring isolators are the core components of subway vibration and noise reduction, so the stability of their performance is particularly important. However, since steel spring isolators are installed under the lower track, it is difficult to implement the stability of their performance in terms of detection and monitoring.

[0004] Most of the existing detection and monitoring devices are installed with detection meters, which results in high cost and cannot cover all the steel spring isolators on the subway track. Generally, they are installed at intervals, and cannot monitor all the steel spring isolators on the entire line. In addition, the structure with monitoring meters also brings great trouble to the later subway operation and maintenance personnel. During maintenance, the cover on the plastic cover of each monitoring meter needs to be opened, and then the pointer changes of the monitoring meter need to be observed to determine whether the use status of the steel spring isolator is stable. Summary of the invention

[0005] The object of the present invention is to provide a simple monitoring device and a monitoring method for a steel spring vibration isolator, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a simple monitoring device for a steel spring vibration isolator, comprising an inner cylinder and an outer cylinder of the steel spring vibration isolator, a magnet is arranged on the top cover plate of the inner cylinder, and the magnet is arranged below the height adjustment seat assembly, a monitor cover assembly is arranged on the outer cylinder, and a connecting rod below the cover plate of the monitor cover assembly assembly is connected to the height adjustment seat assembly.

[0007] As a further improvement to the above technical solution, the height-adjusting seat assembly includes a locking plate, and an adjusting plate is further provided below the locking plate.

[0008] As a further improvement to the above technical solution, the height-adjusting seat assembly also includes a height-adjusting seat bolt connected to the connecting rod.

[0009] As a further improvement to the above technical solution, the monitor cover assembly includes an indicator panel, and the indicator panel is connected to the connecting rod.

[0010] As a further improvement to the above technical solution, the monitor cover assembly is fixedly connected to the outer cylinder by bolts.

[0011] As a further improvement to the above technical solution, the upper surface of the indicator panel is provided with a fluorescent green coating, and the outer surface of the indicator panel is provided with a fluorescent red coating.

[0012] The present invention also provides a monitoring method for a steel spring vibration isolator, comprising the following steps:

[0013] S1: Connect the lower part of the height adjustment seat base to the top cover plate of the inner cylinder of the steel spring vibration isolator, connect the upper part to the height adjustment seat bolts, connect the height adjustment seat bolts to the connecting rods, and connect the connecting rods to the indicator panel, so that all parts form a whole;

[0014] S2: Adjust the height of the bolts of the height adjustment seat so that the indicator panel is in a horizontal state, which is the initial working state;

[0015] S3: When the indicator panel in S2 is always in a horizontal state, the steel spring vibration isolator is working normally; when the indicator panel in S2 is tilted and cannot remain horizontal, the steel spring vibration isolator is working abnormally and needs to be inspected and repaired.

[0016] As a further improvement to the above technical solution, the upper surface of the indicator panel is set to fluorescent green, and the outer surface of the indicator panel is set to fluorescent red.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. Most of the existing detection and monitoring devices are structures for installing detection tables, which are costly and cannot be installed on all steel spring isolators on the entire line. The monitoring device provided in this application has a simple structure and low cost and can cover all steel spring isolators on the subway line.

[0019] 2. The monitoring device of this application is simple in design and easy to install on site. The plastic cover assembly is directly connected to the height adjustment seat assembly, and then the initial working state of the indicator is adjusted to complete the installation.

[0020] 3. The monitoring device provided in this application is convenient for monitoring and testing. It only needs to use a flashlight to illuminate the plastic insulating cover on the steel spring and observe the color change and flip angle of the indicator under the cover to determine whether the actual use status of the steel spring isolator has changed; it greatly improves the detection and maintenance efficiency of subway operation and maintenance personnel.
