Description
Technical field
The utility model relates to mining Equivalent Materials Testing equipment technical field, particularly a kind of coal-face simulation support.
Background technology
The simulation material of pressure sensor as actual coal-face liquid/gas support adopting rigidity in similarity simulation experiment at present more.Rigid pressure sensor has that exist with actual liquid/gas support much can not the drawback of matching, such as: rigid pressure sensor is difficult to realize operation, simultaneously rigid sensor that liquid/gas support just supports and can not realizes the live work, in addition the coal-face liquid/gas support that contract under post of liquid/gas support and can carry out pressure release when overloading and guarantee that the working resistance of liquid/gas support is constant, also cannot accurate simulation in laboratory simulation.
Utility model content
For above-mentioned subproblem, the utility model provides a kind of coal-face simulation support, and described support comprises upper steel plate, air bag and lower steel plate; There is boring one end of described lower steel plate, and described boring is in the centre of the end face parallel with steel plate cross section, and the other end of described lower steel plate is closed; Described lower steel plate also has through hole, and described through hole with in the plane of lower steel plate cross-section normal, and communicates with described boring; On described through hole, have air bag, the upper and lower side of described air bag has mouth; Described mouth is provided with metal flange, and described air bag is connected with upper steel plate or lower steel plate by connector by described metal flange, and the metal flange be connected with lower steel plate has the hole communicated with the through hole of lower steel plate.
By adopting air bag realize the constant-resistance of support and kill the simulation of phenomenon in the utility model.In air bag can topping up body also can inflatable body, when on-the-spot working resistance of support is excessive, can pressure release be facilitated by reducing the medium filled in air bag; And when pressure is lower than setting value, keep the amount of institute's filling medium in air bag constant, conveniently can realize the constant-resistance of support.When work plane abutment pressure is larger, can there is situation about being crushed to death in on-the-spot support, and the utility model can simulate this process equally.When force value is always larger, simulation support upper steel plate will constantly reduce, and finally can cause the phenomenon simulating hydraulic support pushed down.

Detailed description of the invention
In one embodiment, provide a kind of coal-face simulation support, described support comprises upper steel plate, air bag and lower steel plate; There is boring one end of described lower steel plate, and described boring is in the centre of the end face parallel with steel plate cross section, and the other end of described lower steel plate is closed; Described lower steel plate also has through hole, and described through hole with in the plane of lower steel plate cross-section normal, and communicates with described boring; On described through hole, have air bag, the upper and lower side of described air bag has mouth; Described mouth is provided with metal flange, and described air bag is connected with upper steel plate or lower steel plate by connector by described metal flange, and the metal flange be connected with lower steel plate has the hole communicated with the through hole of lower steel plate.
The centre position that described boring is positioned at the side of lower steel plate is stability in order to ensure lower steel plate and tightness, but choosing not special requirement to diameter.By described boring, described support can connect with sebific duct, and for giving the air bag filling medium of support, described medium can be air also can be liquid, preferably, and edible oil.
Described through hole ensures the tightness between air bag and lower steel plate by flange, is used to match-drill to air bags or inflation.
The size of described air bag is little on test impact, and the mining height of Main Basis simulated test is determined.And all communicate due to described air bag, according to isotropic character of gas-liquid, it is all uniform for therefore adopting multiple air bag stressed, but in order to ensure upper steel plate and lower steel plate uniform force, preferably, described air bag is equidistantly arranged evenly between upper steel plate and lower steel plate.And arranging of the concrete quantity of described air bag is arranged according to the length of simulation support, preferably, even number can be adopted.
In order to ensure the tightness between air bag and the through hole of lower steel plate, the upper and lower side of air bag is all fixed with metal flange, and fixes with connector between metal flange and upper steel plate or lower steel plate, and described connector can be screw.And there is mouth air bag lower end, the metal flange therefore for fixation balloon lower end needs to beat corresponding hole.
Be a specific design of the present utility model below in conjunction with attached Fig. 1 and 2.
Fig. 1 is the simulation supporting structure schematic diagram in the utility model embodiment; In figure, 1 is air bag, and 2 is through hole, and 3 is boring, and 4 is upper steel plate, and 5 is lower steel plate; Fig. 2 is the left view that Fig. 1 simulates support; In figure, 1 is air bag, and 3 is boring, and 4 is upper steel plate, and 5 is lower steel plate.Upper steel plate and the long 200mm of lower steel plate in FIG; Wherein, upper steel plate thickness 5mm, lower steel plate thickness 8mm, lower steel plate is equipped with the boring of diameter 4mm; Between upper steel plate and lower steel plate, be evenly distributed with 4 air bags, air bag height 30mm, has the hole of diameter 4mm in the lower end of air bag.
In sum, realize the constant-resistance of support by employing air bag and kill the simulation of phenomenon in the utility model.When on-the-spot working resistance of support is excessive, by reduce institute's filling medium in air bag number facilitate pressure release, and in pressure is lower than maintenance air bag during setting value institute's filling medium amount constant, conveniently can realize the constant-resistance of support.When work plane abutment pressure is larger, can there is situation about being crushed to death in on-the-spot support, and the present invention can simulate this process equally.When force value is always larger, simulation support upper steel plate will constantly reduce, and finally can cause the phenomenon simulating hydraulic support pushed down.
Above to present disclosure has been detailed introduction, applying specific case herein and setting forth principle of the present utility model and embodiment, the explanation of above embodiment just understands method of the present utility model and core concept thereof for helping; Meanwhile, for those skilled in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
