A kind of coal mine support body and tunnel are caving prose style free from parallelism relationship experiments platform, the fixed frame comprising firm banking and be fixedly connected with top end surface surrounding on described firm banking, on described firm banking, top end surface middle is provided with placement elongated slot, the front end of described placement elongated slot is opened on the front end face of firm banking, in described placement elongated slot, subordinate's top end surface left and right edges place is vertically fixedly connected with several hydraulic jack, several hydraulic jack described are along placing elongated slot length direction spaced set, described piston rod of hydraulic jack top is connected with prop inner tip.
The beneficial effects of the utility model are: this experiment table can simulate coal mine roadway be caving in a prose style free from parallelism reproduce rescue passage time, prop is to the interactively being caving a prose style free from parallelism, utilize this testing table can survey in rescue passage Bracing Process to be caving the stressed and frame stressing of prose style free from parallelism displacement, interaction force and prop, can observing simultaneously and be caving a prose style free from parallelism and affect space structure situation of change by rescue ground settlement and tunnel, namely observing being caving prose style free from parallelism space structure from being stabilized to destruction again to stable dynamic process.
accompanying drawing illustrates:
Fig. 1 is one-piece construction schematic diagram of the present utility model.
embodiment:
With reference to Fig. 1, a kind of coal mine support body and tunnel are caving prose style free from parallelism relationship experiments platform, the fixed frame 2 comprising firm banking 1 and be fixedly connected with top end surface surrounding on described firm banking 1, on described firm banking 1, top end surface middle is provided with and places elongated slot 5, the front end of described placement elongated slot 5 is opened on the front end face of firm banking 1, in described placement elongated slot 5, subordinate's top end surface left and right edges place is vertically fixedly connected with several hydraulic jack 4, several hydraulic jack 4 described are along placement elongated slot 5 length direction spaced set, described hydraulic jack 4 piston rod top is connected with prop 7 inner tip, each described hydraulic jack 4 is interconnected by hydraulic tube 8, and described hydraulic tube 8 outer end is fixedly connected with controller 6, the height of cylinder of described hydraulic jack 4 is identical with described placement elongated slot 5 internal depth, described prop 7 height is identical with described placement elongated slot 5 internal depth, described firm banking 1 and described fixed frame 2 are made by metal material, described fixed frame 2 inside is provided with several self-controls and is caving body 3,
Described fixed frame 2 and described prop 7 surfaces externally and internally are equipped with several pressure transducers 9.
Experiment table can be tested as follows:
It is that in middle particle, granule, mixing, particle and granule are caving body (sand or stone) and test prop 7 interactively that experiment table can simulate particle diameter, research is caving body (sand or stone) under the effect of prop 7, is caving mechanics transmission characteristic, the deformation trace of body (sand or stone) and is caving body (sand or stone) space structure situation of change.
Experimental technique:
Prepare similar materials: selection particle diameter ratio and on-the-spot roadway surrounding rock are caving the discrete material that a rear formation prose style free from parallelism meets simulated condition;
Lay discrete material: determine to think in advance that the self-control that test is caving body (sand or stone) deformation trace is caving body 3 location layout, discrete material is formed according to roadway surrounding rock rock stratum and lays respectively, and uniform spreading is located in the fixed frame 2 of firm banking 1 upper surface, when being routed to self-control and being caving body 3 design attitude, place self-control according to the locus of correspondence and be caving body 3, wherein, the height that should be caving by actual roadway surrounding rock determines the placement thickness being caving body (sand or stone) after ratio of similitude converts.After having laid material, can form a natural repose angle is the inclined-plane of θ.
Instrument connects: self-control is caving body 3, the data line of pressure transducer 9 is connected on data collecting instrument, data collecting instrument is connected with data handling system by data connecting line.
Open prop: utilize controller 6 several hydraulic jack 4 to be started simultaneously and slowly rise, prop 7 also moves up thereupon, the prose style free from parallelism that is caving above prop 7 is upwards pushed away, form a support space gradually, along with hydraulic jack 4 continues to rise, placement elongated slot 5 support space formed is increasing, when lifting height reaches side plate height, presses controller 6 and hydraulic jack 4 is stopped rising.
Data acquisition: when hydraulic jack 4 starts to start, data collecting instrument starts image data, boost in process at prop 7, by data acquisition system prop 7 with fixed frame 2 upward pressure sensor 9 and make the data being caving body 3 by oneself, be transferred to data handling system.When hydraulic jack 4 lifting height reaches side plate height, after being caving a prose style free from parallelism and being stable, data collecting instrument stops gathering observation simultaneously and is caving the change of prose style free from parallelism interior spatial structure, and record.
Data analysis: data handling system carries out data analysis, displacement, the stressing conditions of body 3 is caving by analyzing self-control, analyze the stressing conditions on fixed frame 2 and prop 7, draw the mechanics transmission characteristic, the deformation trace that are caving body (sand or stone), thus obtain prop 7 to the interactively being caving a prose style free from parallelism.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned citing, the change that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
