Description

Technical Field

[0002] Conventional bearings are subject to compression and shear during use, and currently bearing tests usually only conduct mechanical property tests under compression. With the development of construction technology, in some cases the bearings are in tension, and pull-out bearings are currently used in some projects. Since conventional testing machines only perform compression and shear tests, currently, except for the ultimate tensile bearing capacity test, tensile bearings basically do not perform tensile and shear tests on the bearings, especially when considering the rotation angle. With the needs of actual projects, there has been a greater demand for mechanical property tests of tension supports in recent years. How to keep the bearing under tension at a certain angle during mechanical property testing is a difficult experimental problem. Utility Model Content

[0029] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0030] like Figure 1-6 As shown, the simple test device for a support with adjustable angle includes:

[0031] A base 1, on the surface of which a guide rail 2 is mounted, on the surface of which a movable vertical testing mechanism is provided, and between the testing mechanism and the base 1 a test piece is provided;

[0032] A reaction wall 11, on the surface of which a horizontal testing mechanism is fixedly mounted, and the horizontal testing mechanism is movably connected to one end of the vertical testing mechanism;

[0033] The lower connecting plate 5 is fixedly mounted to the surface of the base 1 , and a turntable 23 is rotatably connected inside the lower connecting plate 5 . The turntable 23 is transmission-connected to a driving mechanism mounted on the bottom of the base 1 through a square rod 25 .

[0034] The surface of the base 1 is provided with two symmetrically distributed guide rails 2, and the cross-sections of the two guide rails 2 are both T-shaped structures, and the surface of the base 1 located between the two guide rails 2 is provided with a lower connecting plate 5; the vertical testing mechanism includes a slide rail 4 and a top plate 6, and the bottom of the top plate 6 is rotatably connected to four evenly distributed jacks 10, and the telescopic ends of each jack 10 are rotatably connected to the slide rail 4. There are two slide rails 4 and they are all engaged and sliding with the surface of the guide rail 2; the cross-section of the slide rail 4 is a U-shaped structure, and both ends of the slide rail 4 are connected to the telescopic ends of the jack 10. The top of the slide rail 4 is threadedly connected with a knob 15, and a number of evenly distributed positioning holes 3 are opened on the surface of the guide rail 2, and the knob 15 is engaged and plugged into the inside of the positioning hole 3; the bottom of the top plate 6 is provided with an upper connecting plate 7, and the upper connecting plate 7 is distributed corresponding to the base 1 and the lower connecting plate 5, and the top plate 6, the upper connecting plate 7, the lower connecting plate 5 and the base 1 are all penetrated and plugged with bolts 8, and the ends of the bolts 8 are threadedly connected to the nuts 9.

[0035] In the present technical solution, when conducting a tension and compression test on the support, the movable joint 14 is removed, the turntable 23 is removed from the lower connecting plate 5, and then the support is fixed on the base 1 or the lower connecting plate 5, and the support is fixed to the upper connecting plate 7. The top plate 6 and the upper connecting plate 7 are driven upward or downward by the operation of the jack 10, so that the tension and compression of the support can be tested. When conducting an inclination angle test, the top plate 6 and the lower connecting plate 5 are offset to a certain extent by controlling the extension and contraction amount of the jack 10, so that the support can be subjected to force analysis under different forces to ensure the load-bearing requirements of the support during actual use.

[0036] The horizontal testing mechanism includes a horizontal tension and compression actuator 12, which is correspondingly arranged on one side of the top plate 6. The horizontal tension and compression actuator 12 is fixedly installed to the side wall of the reaction wall 11. The telescopic end of the horizontal tension and compression actuator 12 and the side end of the top plate 6 are fixedly connected to the joint 13, and the joints 13 are movably connected through a detachable movable joint 14.

[0037] In this technical solution, when conducting a shear test, the support is fixed between the upper connecting plate 7 and the lower connecting plate 5 using a jack 10. After the support is fixed to the base 1 or the lower connecting plate 5, the knob 15 is unscrewed to allow the slide rail 4 to move, and the horizontal tension and compression actuator 12 is started. The horizontal tension and pressure generated at this time drives the top plate 6 to move, and the top plate 6 drives the slide rail 4 to move synchronously through the pressure of the jack 10, so that when the slide rail 4 moves on the surface of the guide rail 2, since the support is fixed on the base 1, a shear force is generated at the support, and then force analysis is performed under different conditions.

[0038] The bottom of the base 1 is fixedly connected to the support legs 16, and a driving mechanism is provided between the support legs 16; the driving mechanism includes a driving motor 17 and a transmission assembly, the driving motor 17 is fixedly installed to one side of the top of the base 1, and the output end of the driving motor 17 is fixedly connected to the driving wheel 18, and the bottom of the base 1 is rotatably connected to the driven wheel and the pinion 20 respectively, the driven wheel and the pinion 20 are coaxially fixed, and the driven wheel is connected to the driving wheel 18 through a belt; the transmission assembly includes a large gear 22, the large gear 22 is rotatably connected to the bottom of the base 1, and the large gear 22 is meshed with the pinion 20; a positioning block 24 for connecting to a specimen is provided on the surface of the turntable 23, and a square hole for inserting a square rod 25 is opened in the middle of the turntable 23, and the square rod 25 extends to the inside of the large gear 22.

[0039] In this technical solution, when conducting a torsion test of the support, the turntable 23 is embedded in the lower connecting plate 5, the square rod 25 is inserted to realize the connection between the turntable 23 and the large gear 22, the support is fixed on the surface of the turntable 23, and the bottom of the support is limited by the positioning block 24. The support is pressed by the jack 10 and fixed to the upper connecting plate 7, and the drive motor 17 is started. Through the transmission of the belt, the active wheel 18 drives the driven wheel to rotate synchronously, and drives the large gear 22 to rotate when the small gear 20 rotates. The large gear 22 drives the support on the turntable 23 to generate a torsional force through the transmission of the square rod 25, thereby realizing the torque condition test of the support, which can improve the diversity of the stress conditions of the support and ensure that the support can still work stably under complex stress conditions in actual use.
