Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail：
A kind of portable anchor rod anchoring quality detecting instrument designed by the utility model, as shown in Figure 1, it includes transmitting-receiving one
Body formula focus sensor 1, smart mobile phone 2 and tone frequency channel wire 3, the communication ends of the transmitting-receiving integrated focus sensor 1 pass through audio
Line 3 connects the audio line interface of smart mobile phone 2, and transmitting-receiving integrated focus sensor 1 is close to the free end of anchor pole 4, the receipts
Hair integral type focus sensor 1 can receive rock mass 5 and cement sand bed 6 to the anti-of stress wave for exporting stress wave signal
Penetrate signal.
In above-mentioned technical proposal, it is provided with and couples between the transmitting-receiving integrated focus sensor 1 and the free end of anchor pole 4
Agent, using butter or vaseline.
In above-mentioned technical proposal, the frequency range for the stress wave signal that the transmitting-receiving integrated focus sensor 1 exports is
100 hertz~30000 hertz (emission band of super magnetic focus is exactly this scope).
A kind of portable Detection of Bolt Bonding Integrity detection method using above-mentioned detector includes the following steps：
Step 1：It is drilled on rock mass 5 with air drill, then anchors anchor pole 4 in above-mentioned hole, and anchor is filled with cement mortar
Gap between bar 4 and the hole；
Step 2：Transmitting-receiving integrated focus sensor 1 is close to the free end of anchor pole 4, and is passed in transmitting-receiving integrated focus
Daubing coupling agent between the free end of sensor 1 and anchor pole 4；
Step 3：Smart mobile phone 2 is controlled to send control signal to transmitting-receiving integrated focus sensor 1, makes transmitting-receiving integrated shake
Source sensor 1 is to 4 elastic stress wave signal of anchor pole；
Step 4：The stress wave signal sends stress wave signal, stress wave along anchor pole 4 to cement sand bed 6 and rock mass 5
Signal generates reflected signal in cement sand bed 6 and rock mass 5；
Step 5：The transmitting-receiving integrated focus sensor 1 receives the reflected signal of above-mentioned stress wave, while by stress wave
Reflected signal be converted into stress wave digital reflection signals, and stress wave digital reflection signals are sent to smart mobile phone 2；
Step 6：Smart mobile phone 2 carries out data processing to stress wave digital reflection signals and obtains waveform and the time of stress wave
Collection of illustrative plates, if showing that the amplitude of stress wave decays linearly over time in collection of illustrative plates, illustrate the cement sand bed 6 around anchor pole 4
Interior slurry is fully filled with；If showing the amplitude of stress wave nonlinear attenuation at any time in collection of illustrative plates, illustrate around anchor pole 4
Slurry in cement sand bed 6 is not fully filled with.
In the step 6 of above-mentioned technical proposal, smart mobile phone 2 is according between stress wave initial end and the initial end of its back wave
Time difference, and combine the speed that stress wave and back wave are propagated in anchor pole 4 and can calculate the length of anchor pole 4.
The utility model uses Ultrasonic Nondestructive technology, is to belong to full Intelligent detector, can not only detect anchor
The length of bar can also detect the mass defect of anchoring and determine the size and location of defect.In addition, the operation of the utility model
Simplicity, anyone can be tested, and rock-bolt length data and anchoring quality data are directly displayed by mobile phone screen.And
And the power consumption of the utility model is extremely low, it, can also be at any time with changing battery when monoblock battery can continue to use operation 24 small.
The content that this specification is not described in detail belongs to the prior art well known to professional and technical personnel in the field.
