DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Reference Figure 1-4 The present invention provides a concrete material strength testing device, comprising:

[0033] A base body 1 is fixedly connected to an outer frame body, the outer frame body comprises an upper plate 2 and a lower plate 3, and the upper plate 2 and the lower plate 3 are fixedly connected via a reinforcing plate 4;

[0034] The measuring assembly includes a force-applying mechanism, a tension clamping mechanism and a data acquisition mechanism. The force-applying mechanism is arranged on the upper plate 2 and the lower plate 3. The force-applying mechanism is connected to the first bottom plate 5 in a transmission manner. The first bottom plate 5 is arranged between the upper plate 2 and the lower plate 3. A fixing column 6 is fixedly connected to the first bottom plate 5. A cavity 7 is provided on the fixing column 6. A first slider 8 is slidably provided in the cavity 7. A first through hole is provided on the cavity 7. A connecting column 9 is fixedly connected to the first slider 8. The connecting column 9 extends out of the cavity 7 through the first through hole. The connecting column 9 is detachably connected with a conical force block 10, and a tension clamping mechanism is provided on the conical force block 10. The tension clamping mechanism is used to clamp the concrete material 13 to be tested during the tensile test. The conical force block 10 is fixedly connected with a pressure sensor 11, and the cavity 7 is fixedly connected with a pressure sensor 2 12. During the compression test, the pressure sensor 11 is used to measure the compressive force of the concrete material 13 to be tested, and during the tensile test, the pressure sensor 2 12 is used to measure the tensile force of the concrete material 13 to be tested.

[0035] The fixing assembly is used to fix the concrete material 13 to be tested. A second bottom plate 14 is movably arranged between the upper plate 2 and the lower plate 3 . The fixing assembly is arranged on the second bottom plate 14 . A displacement mechanism is arranged on the reinforcing plate 4 . The displacement mechanism is transmission-connected to the second bottom plate 14 .

[0036] In this device, the force-applying mechanism is used to apply external force to the concrete material 13 to be tested when performing compressive strength tests and tensile strength tests. The force-applying mechanism applies force to the first base plate 5, and the first base plate 5 transmits the force to the fixed column 6, and the first slider 8 can slide in the cavity 7.

[0037] When a tensile strength test is required, one end of the concrete material 13 to be tested is first installed on the fixed component, the position of the concrete material 13 to be tested is adjusted by the displacement mechanism, and then the tension clamping mechanism is installed on the conical force block 10. Before installation, the conical force block 10 is first removed, and then the conical force block 10 is installed on the connecting column 9 after installation, and then the concrete material 13 to be tested is clamped by the tension clamping mechanism, and finally a force is applied to the first bottom plate 5 by the force-applying mechanism, the first bottom plate 5 pulls the fixed column 6, and the fixed column 6 moves. The fixed column 6 will pull the conical force block 10 through the connecting column 9, which will make the first slider 8 contact with the pressure sensor 2 12, so that the pressure sensor 2 12 measures the tension exerted on the concrete material 13 to be tested.

[0038] When a compressive strength test is required, one end of the concrete material 13 to be tested is also first installed on the fixed component, and the position of the concrete material 13 to be tested is adjusted by the displacement mechanism. At this time, the tension clamping mechanism is no longer used. The concrete material 13 to be tested must contact the conical force block 10, and the second bottom plate 14 moves until the concrete material 13 to be tested abuts against the pressure sensor 11, and then the second bottom plate 14 stops moving, and the force-applying mechanism applies force to the first bottom plate 5, and the first bottom plate 5 applies thrust to the fixed column 6. When the fixed column 6 moves, the connecting column 9 moves in the first through hole, so that the first slider 8 is away from the pressure sensor 2 12, and the first slider 8 abuts against the side wall of the cavity 7, so that the force can be transmitted to the concrete material 13 to be tested, and the pressure on the concrete material 13 to be tested can be measured by the pressure sensor 11.

[0039] A further optimized solution is that a threaded hole is provided on the conical force block 10, a thread is provided on the connecting column 9, the connecting column 9 is threadedly connected to the threaded hole, a plurality of connecting holes 15 are provided on the conical force block 10, a short rod 16 is inserted into the connecting hole 15, a guard plate 17 is fixedly connected to the short rod 16, and a pressure sensor 11 is located between the guard plate 17 and the conical force block 10.

[0040] The conical force block 10 is detachably connected to the connecting column 9 through threads, and the short rod 16 can move in the connecting hole 15. The protective plate 17 is mainly used to protect the pressure sensor 11. The protective plate 17 can move with the short rod 16. When the compressive strength test is performed, the protective plate 17 will not affect the pressure sensor 11.

[0041] A further optimized solution is that the clamping mechanism includes two arc-shaped force rings 18, the inner edge of the arc-shaped force ring 18 is conical, the arc-shaped force ring 18 is adapted to the conical force block 10, the arc-shaped force ring 18 is fixedly connected to the outside with a first connecting plate 19, the two first connecting plates 19 are rotatably connected in the fixing ring 20, the first connecting plate 19 is fixedly connected with a first clamping plate 21, the two first clamping plates 21 are detachably connected, a first mounting hole is opened on the first clamping plate 21, a first screw 22 is passed through the first mounting hole, and the first screw 22 is detachably connected with a first nut 23.

[0042] The two arc-shaped stress rings 18 are used to be sleeved on the conical stress block 10, and the fixing ring 20 is used to connect the two first connecting plates 19. When performing the tensile strength test, the conical stress block 10 is removed, and then the conical stress block 10 is placed between the two arc-shaped stress rings 18, and then the conical stress block 10 is installed on the connecting column 9, and the two first clamping plates 21 are installed on the concrete material 13 to be tested, and fixed with the first screw 22 and the first nut 23. During installation, the concrete material 13 to be tested cannot cause the pressure sensor 11 to generate force.

[0043] When conducting a tensile strength test, the conical stress block 10 is subjected to tension. Since the outer edge of the conical stress block 10 is conical and the inner edge of the arcuate stress ring 18 is conical, when subjected to tension, the arcuate stress ring 18 will move along the surface of the conical stress block 10, and the two arcuate stress rings 18 will move upward and downward respectively. Since the first connecting plate 19 is rotatably connected in the fixing ring 20, with the connection point of the first connecting plate 19 and the fixing ring 20 as a fulcrum, the end of the first connecting plate 19 away from the arcuate stress ring 18 will move toward the concrete material 13 to be tested, and the upper and lower first connecting plates 19 will squeeze the concrete material 13 to be tested, thereby clamping the concrete material 13 to be tested tighter.

[0044] According to a further optimization scheme, a plurality of first sleeves 24 are fixedly connected to the first connecting plate 19 , a first rotating shaft 25 is fixedly connected inside the fixing ring 20 , the first rotating shaft 25 is rotatably connected inside the first sleeve 24 , and an anti-slip pad 1 is fixedly connected to the first clamping plate 21 .

[0045] The first connecting plate 19 and the fixing ring 20 are rotatably connected by the cooperation of the first rotating shaft 25 and the first sleeve 24 , and the anti-slip pad increases the friction between the first connecting plate 19 and the concrete material 13 to be tested.

[0046] A further optimized solution is provided, in which the force-applying mechanism includes a plurality of first hydraulic cylinders 27 and a plurality of second hydraulic cylinders 29. A first mounting groove 28 is provided on the upper plate 2 and the lower plate 3. The two first mounting grooves 28 are arranged correspondingly. A second slider 30 is slidably arranged in the first mounting groove 28. The first hydraulic cylinder 27 and the second hydraulic cylinder 29 are fixedly connected in the first mounting groove 28. The first hydraulic cylinder 27 and the second hydraulic cylinder 29 are respectively located on both sides of the second slider 30. During the compression test, the first hydraulic cylinder 27 is used, and during the tensile test, the second hydraulic cylinder 29 is used. A second through hole 31 is provided on the upper plate 2 and the lower plate 3. The second through hole 31 is connected to the first mounting groove 28. A first bottom plate 5 is fixedly connected between the two second sliders 30, and the first bottom plate 5 passes through the second through hole 31.

[0047] The second slider 30 slides in the first mounting groove 28. When a compressive strength test is required, the first hydraulic cylinder 27 is started, and the first hydraulic cylinder 27 pushes the second slider 30 to move. The two second sliders 30 push the first base plate 5 to move. When a tensile strength test is required, the second hydraulic cylinder 29 is started, and the second hydraulic cylinder 29 pushes the second slider 30 to move.

[0048] A further optimized solution is that the fixing assembly includes two second connecting plates 32, the second connecting plates 32 are rotatably connected to the second base plate 14, the second connecting plates 32 are rotatably connected to the third connecting plates 33, the third connecting plates 33 are fixedly connected to the second clamping plates 34, the two second clamping plates 34 are detachably connected, and the second base plate 14 is fixedly connected to a fixing block 35, and the fixing block 35 is arranged corresponding to the concrete material 13 to be tested.

[0049] During installation, the concrete material 13 to be tested is brought into contact with the fixing block 35 , and the concrete material 13 to be tested is placed between the two second clamping plates 34 , and then the two second clamping plates 34 are connected together.

[0050] A further optimized solution is that a plurality of second sleeves 36 are fixedly connected to the second base plate 14, a second rotating shaft 37 is fixedly connected to the second connecting plate 32, the second rotating shaft 37 is rotatably connected in the second sleeve 36, a third sleeve 38 is fixedly connected to the second connecting plate 32, a third rotating shaft 39 is fixedly connected to the third connecting plate 33, the third rotating shaft 39 is rotatably connected in the third sleeve 38, a second anti-slip pad 2 is fixedly connected to the second clamping plate 34, a second mounting hole is opened on the second clamping plate 34, a second screw 26 is passed through the second mounting hole, and the second screw 26 is detachably connected to a second nut 40.

[0051] The second connecting plate 32 is rotatably connected to the second base plate 14 through the cooperation of the second sleeve 36 and the second rotating shaft 37. The second connecting plate 32 is rotatably connected to the third connecting plate 33 through the cooperation of the third sleeve 38 and the third rotating shaft 39. The second anti-slip pad 2 can increase the friction between the concrete material 13 to be tested and the third connecting plate 33. The second screw 26 and the second nut 40 are used to connect the two second clamping plates 34.

[0052] A further optimized solution is that a second mounting groove 41 is provided on both the upper plate 2 and the lower plate 3, a third slider 42 is slidably provided in the second mounting groove 41, a third through hole 43 is provided on both the upper plate 2 and the lower plate 3, the third through hole 43 is connected to the second mounting groove 41, the second bottom plate 14 is fixedly connected between the two third sliders 42, and the second bottom plate 14 passes through the third through hole 43.

[0053] The third sliding block 42 slides in the second mounting groove 41 , so that the second bottom plate 14 can move between the upper plate 2 and the lower plate 3 .

[0054] A further optimized solution is that the displacement mechanism includes a threaded column 44 and a connecting tube 45. The connecting tube 45 is fixedly connected to the second base plate 14. The inner edge of the connecting tube 45 is provided with threads. The threaded column 44 and the connecting tube 45 are threadedly connected. The threaded column 44 is rotatably connected to the reinforcing plate 4. The threaded column 44 passes through the reinforcing plate 4. A motor 46 is fixedly connected to the reinforcing plate 4. A first gear 47 is fixedly connected to the output end of the motor 46. A second gear 48 is fixedly connected to the threaded column 44. The first gear 47 is meshed with the second gear 48.

[0055] The motor 46 drives the first gear 47 to rotate, the first gear 47 drives the second gear 48 to rotate, and the second gear 48 drives the threaded column 44 to rotate. Since the threaded column 44 and the connecting pipe 45 are threadedly connected, when the threaded column 44 rotates, the connecting pipe 45 will move, thereby moving the second bottom plate 14. There is no thread at the connection portion between the threaded column 44 and the reinforcing plate 4. When the threaded column 44 rotates on the reinforcing plate 4, the two will not produce relative displacement.

[0056] A further optimized solution is that a fourth through hole is provided on the reinforcing plate 4, a threaded column 44 is passed through the fourth through hole, an annular groove is provided on the reinforcing plate 4, the annular groove is connected to the fourth through hole, a limiting plate 49 is fixedly connected to the threaded column 44, and the limiting plate 49 is rotatably arranged in the annular groove.

[0057] The limiting plate 49 can prevent the threaded column 44 from moving on the reinforcing plate 4 .

[0058] The method for using the device is as follows: before testing, one end of the concrete material 13 to be tested is first installed on the second bottom plate 14, the concrete material 13 to be tested is first abutted against the fixing block 35, and then the concrete material 13 to be tested is placed between the two second clamping plates 34, and the two second clamping plates 34 are connected using the second screw 26 and the second nut 40, and the motor 46 is started, the motor 46 drives the first gear 47 to rotate, the first gear 47 drives the second gear 48 to rotate, and the second gear 48 drives the threaded column 44 to rotate. When the threaded column 44 rotates, the connecting pipe 45 moves, thereby moving the second bottom plate 14, and moving the concrete material 13 to be tested toward the conical force block 10;

[0059] If a tensile strength test is required, the conical force block 10 is removed, and then the conical force block 10 is placed between the two arc-shaped force rings 18, and then the conical force block 10 is installed on the connecting column 9, and the two first clamping plates 21 are installed on the concrete material 13 to be tested, and fixed with the first screw 22 and the first nut 23, and the second hydraulic cylinder 29 is started, and the second hydraulic cylinder 29 pushes the second slider 30 to move, and the second slider 30 drives the first bottom plate 5 to move, and the first bottom plate 5 pulls the fixed column 6, and the fixed column 6 moves. As the fixed column 6 moves, the first slider 8 will contact the pressure sensor 2 12, and the connecting column 9 will pull the first slider 8, and the pressure sensor 2 12 will be subjected to pressure, so that the pressure sensor The second sensor 12 measures the tension exerted on the concrete material 13 to be tested; at the same time, the conical force block 10 is subjected to tension. Since the outer edge of the conical force block 10 is conical and the inner edge of the arcuate force ring 18 is conical, when subjected to tension, the arcuate force ring 18 will move along the surface of the conical force block 10, and the two arcuate force rings 18 will move upward and downward respectively. Since the first connecting plate 19 is rotatably connected in the fixing ring 20, with the connection point of the first connecting plate 19 and the fixing ring 20 as the fulcrum, the end of the first connecting plate 19 away from the arcuate force ring 18 will move toward the concrete material 13 to be tested, and the upper and lower first connecting plates 19 will squeeze the concrete material 13 to be tested, thereby clamping the concrete material 13 to be tested tighter.

[0060] If a compressive strength test is required, a tension clamping mechanism is not required, that is, the arc-shaped force ring 18 and related structures do not need to be installed.
