Background technology
Underground passage is tunneled and ore extraction all needs to excavate deep rock mass or explosion, and the excavation of rock mass and quick-fried
It is broken to produce strong disturbance to protolith, cause tunnel or drilling surrounding rock body to produce the phenomenons such as rupture.Applied in mine working
In the engineerings such as work, chamber and deep tunnel excavation, deep tunnel and tunnel are disturbed by Excavation blasting, or goaf is given a shock
Disturbance etc., there may be dynamic disasters such as rock bursts, destructive power is greatly, serious to threaten underground or tunneling operation personnel and equipment peace
Entirely, the safety in production to mine and tunnel brings hidden danger.Sound emission monitoring technology and equipment can be monitored inside rock mass in real time
Micro rupture signal, catches dynamic disaster and causes calamity precursor information, the disasters such as rock burst, bump can be carried out through signal processing analysis
Prediction.
Existing sound emission monitoring technology generally by sensor embedment drilling, causes the sensor in hole not recyclable,
Monitoring cost is too high.Equally, traditional method in country rock wall surface install sensor, mostly using forms such as welding, but peace
Dress and unloading process are wasted time and energy, and are taken considerable time and human cost.
Therefore the utility model proposes a kind of acoustic transmitter erecting device of Quick-attachable, to realize acoustic emission sensor
The purposes such as recyclable, Fast Installation dismounting.It can be fixedly mounted in advance in the multiple positions of monitored area country rock wall surface simultaneously multiple
Installation chassis, is easy to the flexible Fast Installation of sensor.
Utility model content

Put, the cost of acoustic emission monitor(ing) is ruptured to reduce traditional tunnel or tunnel surrounding.
The device includes installation chassis, installation sleeve, strong magnet, iron plate, spring and installs round platform and spring, and installation chassis is used
Expansion bolt is fixed on country rock wall surface, and installation chassis center, which is left in a circular hole, installation sleeve, sets spring to install round platform, bullet
Spring is caught in spring installation round platform and connected as one with installation sleeve, and spring, which provides extruding force, makes acoustic emission sensor through installation bottom
The center hole of disk is close to country rock wall surface, and strong magnet is fixed on installation chassis, and iron plate is fixed in installation sleeve, installs
Absorption affinity between strong magnet and iron plate of chassis and installation sleeve and form coaxial cooperation.
Wherein, angle is 30 ° -45 ° between the expansion bolt mounting hole and strong magnet mounting hole on installation chassis, to ensure
Sensor is installed interference-free.
The center hole diameter of installation chassis is slightly larger than selected acoustic emission sensor diameter, to pass through center
Circular hole.Absorption affinity is provided by strong magnet and iron plate, it is ensured that sensor is not sent out in monitoring process between installation sleeve and installation chassis
Life comes off.
Installation chassis is pre-installed in country rock wall surface with expansion bolt, and before sensor installation, can be existing according to engineering
Field situation is arranged in the multiple positions of monitored area country rock wall surface point, is easy to the flexible Fast Installation of sensor.
Followed the steps below when using the device：
A. installation chassis is fixed on monitored area country rock wall surface with expansion bolt；
B. it is floating and clean the country rock wall surface in installation chassis centre bore, smear sensor couplant；
C. the installation sleeve that will be equipped with sensor is adsorbed on installation chassis, and makes acoustic emission sensor and country rock wall tight
Close coupling contact, completes the installation of sensor；
When d. dismantling, the installation sleeve that directly will be equipped with sensor pulls away installation chassis, takes out sensor, completes sensing
The dismounting of device.
Above-mentioned technical proposal of the present utility model has the beneficial effect that：
The device can realize the Fast Installation dismounting of acoustic emission sensor, while can be in advance in monitored area country rock wall table
Multiple installation chassis are fixedly mounted in the multiple positions in face, are easy to the flexible Fast Installation of sensor, greatly reduce voice sending sensor
Device cost in use, has saved the means of production.
