Description
Technical Field
The utility model relates to a tunnel country rock deformation monitoring devices, especially a tunnel country rock deformation ultrasonic wave real-time supervision alarm device.
Background
After the underground tunnel is tunneled, due to factors such as internal stress of surrounding rocks, mine pressure and mining stress, the surrounding rocks of the tunnel are deformed to different degrees at different positions, and collapse and other life safety threatening accidents can be caused after the deformation exceeds a stable range, so that the method is particularly important for monitoring the deformation of the tunnel in real time. At present, various measuring devices and methods are widely applied, but because the measuring process is mainly a manual measuring method, the manual measuring method not only can generate certain temporary interference on the measuring device, but also can not truly reflect the deformation condition of the surrounding rock of the roadway because certain errors exist in the conditions of the instrument, the conditions of an observer and the like. The Chinese patent document with application number 201610976614.2 entitled "full-process full-section surface deformation monitoring device and method for full roadway" discloses a full-process full-section surface deformation monitoring device and method for full roadway, and the testing device is complex and the mounting and dismounting processes are complicated.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem that prior art exists, the utility model provides a simple structure, convenient operation, can automatic measure's mining tunnel country rock deformation ultrasonic wave real-time supervision alarm device.
The utility model provides a technical scheme of above-mentioned technical problem is: an ultrasonic real-time monitoring and alarming device for roadway surrounding rock deformation comprises an anchor rod, a tray, a first nut, an external thread sleeve, a first fixing nut, a second fixing nut, a supporting frame, a steering engine, a pin, an ultrasonic sensor probe and a data processor; the anchor rod is the anchor rod of establishing the random point in the tunnel, and the anchor rod afterbody is fastened with the external screw thread sleeve pipe, fixes the tray with first nut on anchor rod afterbody top, and anchor rod afterbody bottom is through the fixed support frame of first fixation nut and second fixation nut on two upper and lower support frames, and support frame central authorities place data processor, and the other end of support frame is with the fixed steering wheel of pin, is equipped with the ultrasonic sensor probe on the steering wheel, and the ultrasonic sensor probe links to each other with data processor.
The technical effects of the utility model reside in that: this measuring device simple structure, convenient operation can realize the automation and the intelligent early warning to tunnel country rock deformation monitoring, reduce the colliery to the human investment in tunnel to a certain extent, can survey the country rock deformation simultaneously, further confirm tunnel stability, prevent because of the emergence of disasters such as roof collapse that the country rock is unstable and cause.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. a roadway; 2. directly ejecting; 3. a base top; 4. an anchor rod; 5. a tray; 6. a nut; 7. an externally threaded sleeve; 8. a fixing nut 1; 9. a fixing nut 2; 10. a support frame; 11. a steering engine; 12. a pin; 13. an ultrasonic sensor probe; 14. a data processor.
Detailed Description
The utility model is further explained with the accompanying drawings and the specific embodiments.
As shown in fig. 1, the utility model comprises an anchor rod 4, a tray 5, a nut 6, an external thread sleeve 7, a fixing nut 8, a fixing nut 1, a supporting frame 10, a steering engine 11, a pin 12, an ultrasonic sensor probe 13 and a data processor 14; the stock 4 is the stock of establishing the optional point in tunnel 1, the stock 4 afterbody is fastened with external screw thread sleeve pipe 7, fix the tray with nut 6 on stock 7 afterbody top, 4 afterbody bottoms of stock are through two upper and lower support frame fixation nuts (8, 9) fixed support frame 10, data processor 14 is placed to support frame 10 central authorities, the other end of support frame 10 is with the fixed steering wheel 11 of pin 12, be equipped with ultrasonic sensor probe 13 on the steering wheel 11, ultrasonic sensor probe 13 links to each other with data processor 14.
The working principle of the utility model is as follows: when the device is used, the steering engine 11 is utilized to drive the ultrasonic sensor probe 13 to rotate, when the rotation angle of the steering engine 11 is reached, the ultrasonic sensor probe 13 on the steering engine 11 carries out distance measurement, and the distance between the roadway surrounding rock and the ultrasonic sensor probe 13 is measured. With the rotation of the steering engine 11, the ultrasonic sensor probe 13 performs one measurement, the steering engine 11 rotates one cycle and then performs the next cycle rotation again, and the ultrasonic sensor probe 13 continues to perform distance measurement. During measurement, the ultrasonic sensor probe 13 transmits the measured distance data to the data processor 14, the data processor 14 compares the period data with the data of the previous period, if the period data exceeds a set early warning value, the data processor gives an alarm, otherwise, the next period measurement is continued. The utility model discloses a distance measurement obtains the change law of central point to obtain the area of tunnel section profile, and then obtain tunnel country rock and warp the rate of change along with measurement cycle, thereby confirm tunnel country rock stability. The utility model discloses can realize reducing the colliery to the human investment in tunnel to a certain extent to the automation and the intelligent early warning of tunnel country rock deformation monitoring, can survey the country rock deformation simultaneously, further confirm tunnel stability, the prevention is because of the emergence of disasters such as roof collapse that the country rock is unstable and cause.
