It should be noted that, the test device is used to test the phosphogypsum plastering mortar workpiece 6 to be tested with the same thickness, so the size of the gear 42 is set, and thus, when the top plate 24 clamps the phosphogypsum plastering mortar workpiece 6 to be tested, the gear 42 can be just meshed with the movable plate 28, so that the linkage operation between the movable plate 28 and the protection plate 41 is realized.
In the embodiment, by arranging the protection mechanism 4, the safety protection function is mainly achieved when the strength test is performed;
the protection plate 41, the movable plate 28 and the gear 42 are mainly utilized to be meshed, when the extrusion block 26 ascends to extrude the phosphogypsum plastering mortar workpiece 6, the protection plate 41 is synchronously closed to form a protection barrier above the phosphogypsum plastering mortar workpiece 6, fragments can be effectively placed to splash upwards, an effective protection effect is achieved on a worker and the test piece 33, the safety during strength test is further improved, after the test is finished, the extrusion block 26 contracts, the protection plate 41 is synchronously unfolded, and the operation is very convenient when the device is used without manual operation of the worker.
The working principle of the research testing device provided by the embodiment is as follows:
step one: when the strength test is performed, the extrusion block 26 is extended by the second electric telescopic rod 27 to move upwards, so that the two movable plates 28 can be unfolded at the left side and the right side, and the two gears 42 can be synchronously rotated by the movement of the two movable plates 28, and finally the two gears 42 can drive the two protection plates 41 to be close to each other until the two protection plates 41 are closed;
step two: at this time, the cambered surface position of the extrusion block 26 is not contacted with the inclined surface block structure of the movable plate 28 any more, but the vertical surface is contacted with the inclined surface block, so that the horizontal extrusion force action is not generated on the top plate 24 any more, at this time, the extrusion block 26 can continue to move upwards, and the movable plate 28 keeps the position unchanged until the extrusion block 26 extrudes and breaks the phosphogypsum plastering mortar workpiece 6;
step three: if the scraps jump out, the scraps are directly contacted with the bottom of the protection plate 41, so that the scraps are effectively intercepted, the scraps cannot outwards move, and after the test is finished, the operation is reversed when the scraps shrink.
The foregoing description is only illustrative of the present invention and is not intended to limit the scope of the invention, and all equivalent structures or equivalent processes or direct or indirect application in other related technical fields are included in the scope of the present invention.
