Lamplight alarm type vibration isolator failure indication device and application thereof

Abstract

The invention relates to the field of rail traffic, in particular to an indication device used in a rail traffic floating ballast bed structure for monitoring failure of a vibration isolator and a floating ballast bed applying the indication device. The indication device comprises an alarm lamp, a battery and a connecting casing pipe. The alarm lamp is fixedly arranged at the top of the connectingcasing pipe, the battery is arranged in a pipe cavity of the connecting casing pipe, one electrode of the battery is connected with one electrode of the alarm lamp through a connecting circuit, the other electrode of the battery is connected with the other electrode of the alarm lamp through a functional circuit, the functional circuit comprises an open circuit and closed circuit control device and two sub circuits, and the open circuit and closed circuit control device is arranged between the two sub circuits and arranged on the lower portion of the connecting casing pipe. The lamplight alarm type vibration isolator failure indication device has the advantages that the structure is simple, manual observation and recognition are easy, and the effect is reliable, the indication device canbe widely applied to the floating ballast bed provided with an internal vibration isolation device, and the market application prospects are quite wide.

Description

technical field [0001] The invention relates to the field of rail transit, in particular to an indicating device for monitoring the failure of a vibration isolator in a rail transit floating ballast bed structure, and a floating ballast bed using the device. Background technique [0002] Vibration and noise are recognized as the most widely affected public hazards, and they are also a problem that needs to be solved urgently in the development of rail transit in recent years. Among the existing rail transit vibration and noise reduction technologies, the most successful practical application is the component floating technology, typically the floating ballast bed technology, which has high vibration isolation efficiency and stable working performance, which has become a consensus in the industry. In order to prevent the natural failure or accidental damage of the elastic elements used to support the floating slab in the floating ballast bed structure, it is necessary to freq...

Problems solved by technology

However, it has been found in practice that the existing mechanical indicating devices have a common defect, that is, poor intuition and difficult observation

This is because, in order to ensure the safety of personnel during emergency evacuation and daily inspections, the length of the mechanical indicating device exposed to the outside of the ballast bed is generally very limited. For working conditions such as tunnels with poor application environments, on the one hand, light It is dark, the judgment standards are not intuitive, there are a large number of them, and the workload is heavy. It is difficult for inspectors to fully realize accurate judgments only by naked eye observation, and it is very easy to miss inspections; The exposed part forms a cover or even buries, which affects the observation effect

[0003] To sum up, the existing mechanical indicating devices are still difficult to fully meet the requirements of engineering use, and cannot completely eliminate the safety hazards in the operation of floating ballast beds
