Detailed description of the invention
The utility model provides a kind of Equivalent Materials Testing support, in order to make the purpose of this utility model, technical scheme and advantage clearer, clear and definite, further describes the utility model below with reference to accompanying drawing and specific embodiment.
As shown in Figure 1, Figure 2 and Figure 3, a kind of Equivalent Materials Testing support, comprises base 1, post chamber 2, support column 4, nut 3, top board 5 and micro pressure sensor 6.Base 1 and top board 5 are rectangular steel plates, offer some cylindrical holes in top board 5, place micro pressure sensor 6; Base 1 is welded with isosceles trapezoid scapus chamber 2, inside have cylindrical hole, hole wall has screw thread; Support column 4 is pillar-bolt, and lower end relies on screw-threaded engagement to embed in post chamber 2, and upper end is welded with top board 5; Nut 3 rotation set, on support column 4, is close to post chamber 2.
The size of support need ensure that the top board of working space is lived in supporting, for the resemble simulation test platform of length × wide × height=2000mm × 220mm × 1800mm, stent support post 4 can be designed without being of a size of length × wide × height=210mm × 40mm × 50mm when propping up, when stent support post 4 is propped up, maximum height is 70mm, if desired larger height, can on base 1 underlay from base 1 upper surface with size but the different steel plate of thickness.
Working method of the present utility model and mechanism are: for the resemble simulation test platform of length × wide × height=2000mm × 220mm × 1800mm, get Equivalent Materials Testing geometric similarity than being 1:100, on-the-spot 1m is equivalent to 10mm in test, when seam mining, first offer and cut eye, cut eye and be of a size of length × wide × height=220mm × 40mm × 50mm, stentplacement is being cut in eye, see Fig. 4, micro pressure sensor lead-in wire 7 on rack plate 5 is connected with microcomputer, with the nut 3 on spanner rotary support post 4, support column 4 is made slowly to increase, treat that the micro pressure sensor 6 on rack plate 5 fully contacts with country rock, and the nut 3 that stops the rotation when producing certain setting load, support is started working, the real time monitor record be connected with micro pressure sensor 6 also preserves the contact data of support and country rock, after new coal body extraction, with spanner counter-rotation nut 3, reduce pressure between support and country rock to certain numerical value, wiping top with pressure traversing carriage, thus make support cycle operation, by contact between microcomputer monitoring support and country rock in the course of work, record is preserved and to data analysis, and then studies the strata-pressure behavior of coal-face.
Should be understood that; the above-mentioned description for concrete test procedure is comparatively detailed; therefore the restriction to the utility model scope of patent protection can not be thought; those of ordinary skill in the art is under enlightenment of the present utility model; do not departing under the ambit that the utility model claim protects; the various deformation such as size, replacement, simple combination can also be made a change; these all fall within protection domain of the present utility model, and request protection domain of the present utility model should be as the criterion with claims.
