Grasp underground monitoring result.With the extensive use of optical fiber transmission technique and the popularization of safety of coal mines high-efficiency mining theory, top plate
The mode of delamination monitoring device towards on-line monitoring develops.Accordingly, it is capable to no a new delamination monitoring equipment of design, overcomes above-mentioned
Defect, turn into those skilled in the art and solve the problems, such as in a hurry.
【The content of the invention】
The utility model is intended to overcome the shortcomings of the prior art, changes electricity using optical fiber transmission technique and displacement signal
Signalling technique, devise it is a kind of can long-distance transmissions, the ore deposit pressure of the displacement of different rock-layers position above top plate can be monitored in real time
Monitoring device.
A kind of coal mine roof plate rock deformation monitoring device, including anchorage head, the anchorage head are fixed on from drift section to top
Plate and through in the drilling of different layers position, the end of the anchorage head is provided with the displacement detector of detection rock depression amount, should
Displacement detector is led to outside drilling by transmission cable, obtains the deflection data of the rock stratum.
Institute's displacement sensing device is embedded in anchorage head, displacement detector is formed entirety with anchorage head.
Institute's displacement sensing device is in the confined space of anchorage head, cable and the confined space seamless combination of transmission.
The anchorage head is arranged in drilling by guide rod.
The detection means further comprises the substation outside drilling；To top plate and different layers position is passed through from drift section
Drilling has two, and the anchorage head for being fixed on different depth is separately installed with each drilling, and each drilling is outer to be provided with one point
Stand, the displacement detector of different depth is according to the relevant position being sequentially connected respectively to Sub Ammunition Supply Poi.
One end of the anchorage head is connected with rope, the difference that the anchorage head position of different depth passes through the rope in drilling
Length determines.
Compared with prior art, the utility model at least has the advantages that：The utility model is installed in drilling
There is displacement detector, the displacement detector is led to outside drilling by transmission cable, to obtain the deflection data of rock stratum.This
Utility model is by the deflection data of displacement detector rock stratum, and can constantly grasps the monitoring result of underground on well.
【Brief description of the drawings】
Fig. 1 is the utility model structure diagram；
Fig. 2 is the utility model anchorage head schematic diagram；
Wherein, 1 it is displacement transducer, 2 be anchorage head, 3 be steel wire rope, 4 be cable, 5 is closed baffle plate.
【Embodiment】
The utility model is intended to overcome the shortcomings of the prior art, changes electricity using optical fiber transmission technique and displacement signal
Signalling technique, devise it is a kind of can long-distance transmissions, the ore deposit pressure of the displacement of different rock-layers position above top plate can be monitored in real time
Monitoring device.
In order to realize the purpose, the technical solution adopted in the utility model is such, and a kind of coal mine roof plate rock stratum becomes
Shape monitoring device, the device is mainly by displacement transducer 1, anchorage head 2, steel wire rope 3, substation, cable 4, (FBG) demodulator, calculating unit
Into.Described displacement transducer 1 is embedded in anchorage head；One end of the cable 4 is connected with displacement transducer 1, the other end
It is connected with substation, real-time Transmission related data；The substation is connected with (FBG) demodulator input, the output end of described (FBG) demodulator with
Computer connects on well.
The utility model is further described with reference to Fig. 1：
Two drillings for passing through different layers position are played to top plate in the next drift section diverse location of coal mine, will using guide rod
The anchorage head 2 of three different depths is separately mounted in two drillings, and the displacement transducer 1 in anchorage head 2 is respectively through different length
The guiding of cable 4 of degree is outer to drilling, and a drilling sets a substation, by the cable 4 in a drilling by the big of different depth
Small order is coupled with the relevant position of phase Sub Ammunition Supply Poi, and displacement transducer 1 at the drilling different depth is obtained data by substation
It is unified to be sent to ground through Transmission Fibers, by the processing of (FBG) demodulator, obtain the data that computer can identify, i.e. different depth
The size of relevant position displacement obtained by place's displacement transducer.It is different in ground real-time monitored underworkings top plate so as to realize
The deflection of opening position, it is poor that the deflection of two positions is made, and the difference of gained should be the absciss layer between two anchorage head positions
Amount, then realize whether absciss layer and absciss layer amount are how many on-line monitorings to back.
The utility model is further described with reference to Fig. 2：
Similar with traditional roof separation indicator, there are six claws the outside of anchorage head 2, plays fixed in back drilling
Effect, unlike traditional roof separation indicator, inlayed inside anchorage head 2 and be fixed with displacement transducer 1, make displacement sensing
Device 1 and anchorage head 2 form an entirety, and they are moved with the sinking of corresponding rock stratum in drilling, obtained by displacement transducer 1
Displacement be the borehole anchorage opening position rock stratum deflection, numerical value caused by displacement transducer 1 by cable 4 draw bore
Hole, it is connected with the observation substation of the drilling, then transmitting to ground-based computer by transmission cable, realize the effect of on-line monitoring
Fruit.In order that anchorage head 2 can be fixed on corresponding position in drilling, anchorage head 2 draws a steel wire rope 3, different depth in drilling
Anchorage head position determined by the different length of steel wire rope 3.
