Sound amplification type point inspection bar

Technical Field

The utility model belongs to the technical field of the utility model, particularly, the utility model relates to a stick is examined to public address formula point.

Background

In the industries of metallurgy, chemical engineering and the like, mechanical equipment is operated continuously. In order to ensure the integrity of the equipment, the equipment needs to be checked at irregular intervals of 24 hours, wherein the indexes comprise temperature, vibration, sound and the like. Although the temperature and the vibration can be displayed by reading of an instrument, the sound is not displayed by the instrument, the auscultation must be carried out by human experience, more than 90 percent of equipment does not exist in a factory building independently and often runs together with other units, so that the problem of sound interference exists, and more than part of equipment, such as a steam turbine, is wrapped by heat insulation materials, so that the actual sound of a single unit is often not true to hear, so that a plurality of faults are missed to be diagnosed or are difficult to capture.

When the point is examined, the current majority of the operating personnel of enterprise are examined the auscultation with bottle opener, spanner temporarily, some even pick up a rod auscultation on the scene, neither safe, also inaccurate, also have some enterprises to adopt the pole auscultation equipment of examining.

The sound source touch-measuring end and the sound conducting rod are integrally cast by solid stainless steel. The point inspection rod is of a solid structure, mechanical abnormal sounds are difficult to capture, for example, the defect sounds of the rolling bearing are difficult to hear due to the fact that the rolling bearing comprises a retainer, an inner ring, an outer ring, balls and other parts, and trouble is brought to fault analysis. In addition, in a plurality of large-scale equipment plants, the problem of mutual interference exists when original sounds are listened, the listening difficulty is high, and the distortion is easy.

In addition, when a screwdriver, a wrench or an existing point inspection rod is used for listening to sound, auscultation is difficult due to the limited length, and for example, due to personal safety, auscultation cannot be performed on equipment which is large in heat preservation thickness, high in temperature or difficult to approach on site.
