Embodiment
Further clear, complete explanation is done to the present invention with reference to specific embodiment.
As shown in figure 1, stope mining machinery simulator stand of the present invention, it includes main body simulation frame 1 and control system, its
It is to simulate frame 1 as main body by the framework of cuboid, lays coal seam successively from bottom to top inside main body simulation frame 1, directly pushes up
Layer, basic top layer and overlying load layer, wherein, coal seam, direct top layer and overlying load layer segment are same as the prior art, i.e. coal
Layer is simulated by aerated capsule 2, and direct top layer is simulated by polyvinyl chloride block 3, and overlying load layer 5 is simulated by blob of viscose two.
The improvements of the present invention are the simulations of basic top layer 4, and as shown in Figure 2 and Figure 3, base object model is by iron block main body 10, solid
Determine blob of viscose 2 11 and detachable blob of viscose 12 forms, blob of viscose is adhesively fixed at the both ends of iron block main body positioned at centre in iron block main body 10
One 8 and fixed blob of viscose 2 11, due in experimentation, in fracture advancing side from double pin hinges 9 to the iron block main body 10
With fixed blob of viscose 2 11 tentatively fix, then four bolts hole are set respectively in the both sides of this pair of pin hinge 9, pass through bolt
13 and nut 14 iron block of required size and blob of viscose assembly are fastenedly connected, fracture advancing side be provided with magnet 6 and rank
Iron 7, the magnet 6 and armature 7 are connected with control system, by magnetic valve therein come control the attraction of magnet 6 and armature 7 or
Disconnect, the quantity by changing the detachable blob of viscose 12 of grafting can simulate the base object model of different top fracture step, and base object model breaks
Split by solenoid valve control, when coal seam is advanced into base object model fracture step, solenoid valve control base object model is broken.
As shown in Fig. 2 the shape of fixed blob of viscose 1 and fixed blob of viscose 2 11 differs, such as fixed blob of viscose 1 is pars intermedia
It is divided into convex, the fixed center section of blob of viscose 2 11 is spill, accordingly, in the detachable blob of viscose plugged with fixed blob of viscose 1
Between be partly spill, the detachable blob of viscose center section plugged with fixed blob of viscose 2 11 is convex, by the thickness of detachable blob of viscose
Degree is arranged to 5cm, 6cm, 7cm, 8cm or 10cm, can simulate the base object model of different-thickness.
The specifically used method of testing stand of the present invention is elaborated below.
The iron block and blob of viscose assembly size of simulation respective thickness base object model are calculated first, from the iron of 5 kinds of different-thickness
The combination of the size can be met by choosing in block main body 10, and iron block main body 10 is one whole with fixed blob of viscose 1, fixed blob of viscose 2 11
Body, fastened with bolt 13 and nut 14；
Then two iron block main bodys 10 are linked together with correspondingly sized double pin hinges 9 again, double both sides of pin hinge 9 it is every
Attraction and disconnection to magnet 6 and armature 7 is by solenoid valve control, and at the same time, the size of detachable blob of viscose 12 should be also improved to
Five kinds of different-thickness of 5cm, 6cm, 7c, 8cm, 10cm, so as to smoothly with the fixation blob of viscose 1 in iron block main body 10, solid
Determine blob of viscose 2 11 and carry out grafting, make the assembly of whole simulation base object model turn into a continuous structure.
Using base object model breaking span as the quantity according to the detachable blob of viscose 12 of decision, make the iron block and glue of the basic top layer of simulation
The broken mechanics of block assembly and the broken mechanics of base object model meet the proportionate relationship set by the mechanical analogue.Simulation is finished in combination
After the iron block and blob of viscose assembly of base object model, aerated capsule 2 is layered on to the bottom of main body simulation frame 1, each aerated capsule 2
A pressure sensor is placed in bottom, and pressure sensor is connected with computer control system, and polyvinyl chloride block 3 is layered on aerated capsule
2 upper stratas, the number of plies of polyvinyl chloride block 3 determine according to the immediate roof thickness simulated, by simulate basic top layer iron block main body and
Blob of viscose assembly (fixed blob of viscose and detachable blob of viscose) is layered on the top of polyvinyl chloride block 3；
Finally spread simulation overlying load layer required for the corresponding secondary number of plies blob of viscose two, model has been laid, computer control
System processed control magnetic valve make each pair magnet 6 and armature 7 all in attraction state and control magnetic valve by aerated capsule 2 from a left side to
The right simulation advance of the face of deflating successively, when the coal body that rubber pneumatic bag 2 is simulated is advanced at base object model broken mechanics, magnetic valve control
The magnet 6 and armature 7 of system are in the off-state not attracted, and the iron block 10 of double both sides of pin hinge 9 is formed disrumpent feelings be hinged knot
Configuration state, the first breaking of base object model is simulated with this.
Iron block and blob of viscose structure after the present invention improves can stack combinations turn into and simulate actual base object model thickness institute
Any physical dimension needed, adds the applicability of equipment and the accuracy of experimental data.
It should be noted that the detachable blob of viscose of the present invention be not limited to it is above-mentioned enumerate several, those skilled in the art exist
Under the guide of the present invention, coming for the different base object models of adaptation all should be in protection scope of the present invention to blob of viscose thickness change made
Within.
