Embodiment
Below in conjunction with specific embodiment, explanation clear, complete is further done to the present invention.
As shown in Figure 1, stope mining machinery simulator stand of the present invention, it comprises main body simulation frame 1 and control system, it simulates frame 1 by the framework of rectangular parallelepiped as main body, main body simulation frame 1 inside lay successively from bottom to top coal seam, directly top layer, basic top layer and on cover load layer, wherein, coal seam, directly top layer and on to cover load layer segment same as the prior art, namely coal seam is simulated by aerated capsule 2, direct top layer is simulated by Polyvinylchloride block 3, above covers load layer 5 and is simulated by blob of viscose two.
Improvements of the present invention are simulations of basic top layer 4, as Fig. 2, shown in Fig. 3, base object model is by iron block main body 10, fixing blob of viscose 11 and detachable blob of viscose 12 form, iron block main body 10 is positioned at centre, at the fixing blob of viscose 8 of the two ends of iron block main body bonding and fixing blob of viscose 11, due in experimentation, two pin hinge 9 is selected tentatively to fix this iron block main body 10 and fixing blob of viscose 11 at fracture advancing side, then four bolts hole are set respectively in the both sides of this pair of pin hinge 9, by bolt 13 and nut 14, the iron block of required size and blob of viscose assembly are fastenedly connected, fracture advancing side is provided with magnet 6 and armature 7, this magnet 6 is connected with control system with armature 7, attraction or the disconnection of controlling magnet 6 and armature 7 is come by solenoid valve wherein, the base object model of different top fracture step can be simulated by the quantity changing the detachable blob of viscose 12 of grafting, the fracture of base object model is by solenoid control, the solenoid control base object model fracture when coal seam is advanced into base object model fracture step.
As shown in Figure 2, fixing blob of viscose 8 is not identical with the shape of fixing blob of viscose 11, as fixing blob of viscose 8 for center section is convex, fixing blob of viscose 11 center section is spill, accordingly, the detachable blob of viscose center section plugged with fixing blob of viscose 8 is spill, and the detachable blob of viscose center section plugged with fixing blob of viscose 11 is convex, the thickness of detachable blob of viscose is set to 5cm, 6cm, 7cm, 8cm or 10cm, the base object model of different-thickness can be simulated.
Below the concrete using method of testing table of the present invention is elaborated.
First iron block and the blob of viscose assembly size of simulation respective thickness base object model is calculated, the combination that can meet this size is chosen from the iron block main body 10 of 5 kinds of different-thickness, iron block main body 10 and fixing blob of viscose 8,11 as a whole, with bolt 13 and nut 14 it is fastening good;
And then with two pin hinges 9 of corresponding size, two iron block main bodys 10 are linked together, two often pair of magnet 6 of pin hinge 9 both sides and the attraction of armature 7 and disconnect by solenoid control, meanwhile, the size of detachable blob of viscose 12 also should be improved to 5cm, 6cm, 7c, 8cm, 10cm five kinds of different-thickness, thus grafting can be carried out with the fixing blob of viscose 8,11 in iron block main body 10 smoothly, make the assembly of whole simulation base object model become a continuous print structure.
With base object model breaking span for according to determining the quantity of detachable blob of viscose 12, the iron block of the basic top layer of simulation and the broken mechanics of blob of viscose assembly and the broken mechanics of base object model is made to meet proportionate relationship set by this mechanical analogue.After the iron block and blob of viscose assembly of the complete simulation base object model of combination, aerated capsule 2 is layered on the bottom of main body simulation frame 1, a pressure transducer is placed in each aerated capsule 2 bottom, pressure transducer and computer control system are connected, Polyvinylchloride block 3 is layered on aerated capsule 2 upper strata, the number of plies of Polyvinylchloride block 3 determines according to simulated immediate roof thickness, the iron block main body of the basic top layer of simulation and blob of viscose assembly (fixing blob of viscose and detachable blob of viscose) is layered on the top of Polyvinylchloride block 3;
Finally spread the blob of viscose two simulation being covered corresponding the number of plies required for load layer, model has been laid, computer control system Controlling solenoid valve makes often pair of magnet 6 and armature 7 all be in attraction state, and and aerated capsule 2 is from left to right exitted by Controlling solenoid valve successively, analog operation face advances, when the coal body that rubber pneumatic bag 2 is simulated is advanced to base object model broken mechanics place, magnet 6 and the armature 7 of solenoid control are in the off-state do not attracted, make the iron block 10 of two pin hinge 9 both sides form disrumpent feelings hinged structural form, simulate the first breaking of base object model with this.
Iron block after the present invention improves and blob of viscose structure stack combinations can become any physical dimension simulated required for actual base object model thickness, add 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 above-mentioned exemplify several, those skilled in the art, all should within protection scope of the present invention to the change that blob of viscose thickness is made for adapting to different base object model under guide of the present invention.
