Description
Technical field
This utility model is related to a kind of device judging Drift stability.
Background technology
With the transfer dug up mine to deep, the lane being caused by mining influence, coal and gas prominent, bump, gushing water etc.
Road unstable factor gradually increases.In the last few years, unstability accident in tunnel got more and more, but the complexity due to geological conditions, lane
Road whether unstability, often cannot judge in advance.When therefore unstability accident in tunnel occurs, nearby staff cannot have in time
The evacuation of effect, thus result in the generation of casualty accident.
The method of existing Drift stability detection mainly has：Acoustic-emission, electromagnetic radiation method, optical fiber, resistance stressometer etc..
But the most high cost of above equipment, easily disturbed by external environment, troublesome poeration, popularization degree is limited.Therefore, invent a kind of letter
Single, effective, can accurately judge Drift stability, the device preventing in real time can be accomplished, it appears particularly important again.
Content of the invention
In order to solve above-mentioned technical problem, this utility model provides a kind of structure simple, can accurately and effectively judge lane
The device judging Drift stability of road stability.
The technical solution adopted in the utility model is：At multiple anchor poles, data acquisition and signal projector and signal
Reason device；Described multiple anchor poles are squeezed into the top board in tunnel, base plate respectively, two are helped and help at angle, in same section；Anchor pole
Exposed junction is fixed by pallet and nut；It is provided with flat jack, flat jack is connected with pressure gauge between pallet and nut；Multiple pressure
Table is connected with signal projector with data acquisition respectively, and data acquisition and signal projector transmit a signal to signal processor, letter
Number processor is connected with siren.
In the above-mentioned device judging Drift stability, also include signal terminal and surface signal terminal；Data is adopted
Collection and signal projector are by transmission of wireless signals to signal terminal；Signal terminal is by transmission of wireless signals to surface signal
Turn station；Surface signal terminal transmits a signal to signal processor.
In the above-mentioned device judging Drift stability, also include underground siren, underground siren being capable of receipt signal
The wireless alarm signal of processor, sends alarm.
Operation principle of the present utility model is as follows：
Data acquisition of the present utility model and signal projector gather a tunnel at interval of certain time at pressure gauge
The stressing conditions of each anchor pole of same section, and data signal is wirelessly transmitted to shaft bottom signal transfer base station, signal transfer base station
Again by the signal transfer base station of transmission of wireless signals to earth's surface, then transmit to signal processor.By signal processor to anchor pole
Each time period stressing conditions are analyzed, and draw out each rockbolt stress and change over curve chart, and all anchors of same section
The weighted mean of bar stress changes over curve chart, and sets the bound of rockbolt stress.
When each rockbolt stress changes over curve chart a certain moment rockbolt stress value and exceeds the bound that we set,
Now anchor pole has the probability of potential unstability, and signal processor sends information warning, reminds earth's surface staff to notice shaft bottom lane
The steadiness in road.When the weighted mean of all rockbolt stress of same section change over curve chart occur kick or
The change of higher magnitude, beyond our setting curves bound when, now it can be assumed that this drift section has the possibility of unstability
Property.Control earth's surface siren to send alarm, remind and have the staff near unstability danger drift section to withdraw.
Compared with prior art, the beneficial effects of the utility model
1）This utility model structure is simple, easy to implement, and can accurately and effectively judge Drift stability；
2）This utility model can carry out real-time monitoring to roadway supported by bolt, can be directly acquainted with the stress shape of each anchor pole
State, by the monitoring to rockbolt stress, can make mining industry personnel grasp the stability of roadway surrounding rock, be conducive to tunnel construction and
Safeguard；
3）This utility model can be used as long term monitoring, and the data of its collection is to roadway surrounding rock mechanical analyses, Drift stability
Analysis plays the role of important.
4）By rockbolt stress curvilinear motion figure in time, the stressing conditions of each anchor pole can be directly acquainted with, facilitate work
Make personnel in time to roadway support weak area strengthening supporting.
Brief description
Fig. 1 is this utility model area monitoring's deployment scenarios schematic diagram on roadway supported by bolt section.
Fig. 2 is the structure chart of anchor pole of the present utility model.
Fig. 3 is this utility model signal transmission route schematic diagram.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is further described.
As Figure 1-3, this utility model includes multiple anchor poles 3, data acquisition and signal projector 1, signal terminal
11st, the signal terminal 12 of earth's surface and signal processor 13；Described multiple anchor poles 3 squeeze into respectively the top board in tunnel, base plate, two
At side and side angle, in same section.The exposed junction of anchor pole 3 passes through pallet 7 and nut 5 is fixing；Between pallet 7 and nut 5
It is provided with flat jack 6, flat jack 6 is connected with pressure gauge 8.Multiple pressure gauges 8 are connected with signal projector 1 with data acquisition respectively,
Data acquisition and signal projector 1 are by transmission of wireless signals to signal terminal 11；Signal terminal 11 is by transmission of wireless signals
Signal terminal 12 to earth's surface；Surface signal terminal 12 transmits a signal to signal processor 13, signal processor 13 with
Siren 14 connects, and signal processor 13 transmits wireless alarm signal to underground siren 4.
This utility model implementation process is as follows：
1) geological conditions according to roadway surrounding rock and adjoining rock stability implementations, carry out region division to tunnel.Choose unstable
Determine region and need the region of monitoring to be monitored.
2) along the drift section needing monitoring, toward its top board, base plate, two help and help to squeeze into respectively anchor pole 4 at angle,
Flat jack 6, the pressure suffered by real-time monitoring anchor pole 4 is loaded onto between the nut 5 of anchor pole exposed junction and pallet 7.By data acquisition with
Signal projector 1 is connected with the pressure gauge 3 of flat jack on the anchor pole 4 of same drift section respectively by data line 2, real
When collection pressure gauge 3 on display each anchor pole 4 stressing conditions.
3) data signal is wirelessly transmitted to signal terminal 11, signal terminal 11 by data acquisition and signal projector 1
Again by transmission of wireless signals to surface signal terminal 12, surface signal terminal 12 transmits a signal to signal processor again
13, finally received by signal processor 13, process.
5) by signal processor 13, to anchor pole 4, each time period stressing conditions are analyzed, draw out each rockbolt stress with
Time changing curve figure, and the weighted mean of all rockbolt stress of same section changes over curve chart, and set anchor
The bound of bar stress.When a certain value of each rockbolt stress exceeds the bound that we set, what now anchor pole had a unstability can
Energy property, computer sends information warning, reminds earth's surface staff to notice the steadiness in shaft bottom tunnel.And once same disconnected
There is the change of kick or higher magnitude and exceed the upper and lower of our setting curves in the weighted mean of all rockbolt stress in face
In limited time, now it can be assumed that this drift section has the probability of unstability, signal processor 13 sends a warning, and sounds police simultaneously
Report device 14 and underground siren 4, remind the staff near work surface to withdraw.
