Background technique
Sound emission is a kind of important non-destructive testing technology.Before solid deformation or destruction, small deformation or fine crack Occurrence and development all with the generation of sound emission, can predict and find at this time material by the detection of acoustic emission sensor Or the defect or breakage of structure.From ultrasonic monitoring, ray detection and vortex monitoring etc. lossless detection methods it is different, sound emission examine Measuring tool is there are three advantage as is evident below: (1) can real-time monitoring plastic deformation or micro-damage progress;(2) multiple sound are used Emission sensor can demarcate defective locations;(3) equipment in operating can also be diagnosed.
The acoustic emission system of complete set is by acoustic emission sensor, mininoise cable, preamplifier part, coaxial cable and A few part compositions of sound emission resolver.Wherein acoustic emission sensor is used to contact with detecting object, is used as sound emission letter Number acquisition device;Amplifier is used to amplify very faint sound and signals, meanwhile, filter circuit is used to eliminate unwanted letter Number;Mininoise cable connects sensor and amplifier;Sound emission resolver for collected acoustic emission signal display and Data Management Analysis;Coaxial cable connects preamplifier and sound emission resolver.
The fixation quality of acoustic emission sensor is directly related to the effect of detection.Currently, in order to guarantee acoustic emission sensor Close contact can be kept with examined object, directly be applied to acoustic emission sensor surface frequently with 502 glue etc..Although smearing 502 glue can guarantee that sensor and examined object keep being in close contact, but such method is used for a long time to voice sending sensor The damage of device be it is very big, acoustic emission sensor surface size can be made to thicken, acoustic emission sensor acquire signal capabilities weaken, And glue has certain corrosivity, causes the abrasion of acoustic emission sensor.
Summary of the invention
The present invention in order to solve shortcoming in the prior art, provide it is a kind of convenient for operation, highly reliable, repeatable benefit The detection of side formula acoustic emission sensor fixed device and its installing and fixing method.
In order to solve the above technical problems, the present invention adopts the following technical scheme: side formula acoustic emission sensor detection fixation The shell on high resiliency rubber band is arranged in several including high resiliency rubber band in a ring in device, and each shell is in one end The outer middle side part of open cylindrical structure, the end face that shell blocks is provided with connection ring, and notch is provided in connection ring, high Elastic rubber band passes through notch and is threaded through in connection ring, and a side formula acoustic emission sensor, side formula sound are provided in each shell The probe of emission sensor is towards the open end of shell.
Shell is along the circumferential direction uniformly provided with several cable clamping interfaces, and the length direction of every cable clamping interface is each parallel to shell Center line, one end of cable clamping interface flushes and is connected to the edge of shell open end.
The side formula acoustic emission sensor detection installing and fixing method of fixed device, includes the following steps,
(1), side formula acoustic emission sensor is installed in shell, while the lead of side formula acoustic emission sensor side is passed through most In close and corresponding cable clamping interface;
(2), by high resiliency rubber band sleeve in the outside portion of examined object;
(3), in the cage connection to high resiliency rubber band equipped with side formula acoustic emission sensor, i.e., high resiliency rubber band local elongation becomes Then shell opening end face is contacted with examined object surface through in connection ring by the notch in connection ring after thin;
(4), the periphery of examined object is uniformly arranged several and the outer of side formula acoustic emission sensor is housed by repetition step (3) Shell, under the action of high resiliency rubber band, all shell opening end faces are contacted with the press of examined object surface;
(5), the lead of side formula acoustic emission sensor and acoustic emission system are connected, carries out wave velocity testing, works as wave velocity testing As a result when consistent with the theoretical velocity of wave of examined object, show that acoustic emission sensor has been close to examined object;
(6), after the completion of detecting, will successively be removed from high resiliency rubber band equipped with the shell of side formula acoustic emission sensor, finally from High resiliency rubber band is removed in examined object, next time, detection was used again.
By adopting the above technical scheme, the cable clamping interface in the present invention is arranged several, can facilitate respective side formula sound emission in this way The lead of sensor makes lead be convenient for drawing from cable clamping interface.
Present invention can ensure that the fixed effect of acoustic emission sensor, the current acoustic emission sensor of effective solution is fixed Problem, have structure it is simple, convenient for high-efficient, it is economical, it is reusable, it is applied widely, and will not be to voice sending sensor The advantages of device damages.
