[0002] As a civil engineering material most widely used at present, the compressive strength of concrete is very important. Especially for those buildings mainly made of concrete, the compressive strength of concrete can directly affect the safety of these buildings. The detection of the compressive strength performance of concrete often needs to be carried out through multiple groups of concrete test blocks, and these concrete test blocks have to go through a series of processes such as pouring, demolding, and curing. After curing, a fracturing experiment needs to be carried out on the concrete test blocks to detect the compressive strength of the test blocks.

[0003] In the prior art, usually, a compressive strength testing device is used to test the compressive strength of concrete test blocks. The concrete test blocks are prone to crack under the action of pressure and splash many fragments. Since continuous testing is often adopted in the testing process, after each test, it is necessary to clean the fragments generated by the cracking of the concrete test blocks. However, the existing cleaning method often cleans the fragments by manually holding tools, and the cleaning efficiency is relatively low. Summary of the Utility Model

[0024] Please refer to Figures 1 to 3 , and now the concrete test block compressive strength testing device provided by the present invention will be described. The concrete test block compressive strength testing device includes a workbench 10, a pressing member 20, two baffles 40, a pushing plate 50, a swing plate 60, and a cleaning member 80. A bracket 11 and a placing table 12 for placing concrete test blocks are provided on the top of the workbench 10; the pressing member 20 is disposed on the top of the bracket 11 and extends downward for pressing the concrete test blocks; the two baffles 40 are oppositely disposed on the top of the placing table 12 and are respectively disposed near both sides of the placing table 12, and the plate surfaces of the baffles 40 extend in the up-and-down direction; the pushing plate 50 is disposed between the two baffles 40, and the two side edges thereof are respectively slidably engaged with the two baffles 40. A first telescopic member 51 extending in the direction perpendicular to the interval between the two baffles 40 is connected to the outer side wall of the pushing plate 50. The telescopic end of the first telescopic member 51 is connected to the pushing plate 50, and the fixed end is connected to the workbench 10 for driving the pushing plate 50 to push the concrete fragments to the outside of the placing table 12; the swing plate 60 is disposed between the two baffles 40 and is oppositely disposed to the pushing plate 50. The two side edges of the swing plate 60 are respectively rotatably connected to the two baffles 40 through rotating shafts 61. The rotating shafts 61 are located at the upper part of the swing plate 60. The pushing plate 50 can push the swing plate 60 to swing vertically, and the swing plate 60 is locked by a locking member 70; the cleaning member 80 is disposed on the outer side wall of the pushing plate 50 for scrubbing the placing table 12 under the drive of the pushing plate 50.

[0025] The embodiment of the present application provides a device for testing the compressive strength of concrete test blocks. During its actual use, the concrete test block to be tested is placed on the placement table 12, and the pressing member 20 presses down the concrete test block until it breaks. The test data is recorded. After the test is completed, the pressing member 20 rises, and the first telescopic member 51 drives the push plate 50 to push the concrete fragments, moving in the direction close to the swing plate 60 until the concrete fragments push the swing plate 60 to swing vertically to avoid the concrete fragments, so that they fall into the collection box pre-placed outside the placement table 12. While the push plate 50 pushes the concrete fragments, the cleaning member 80 follows behind to rub the remaining concrete residues on the placement table 12, realizing the rapid cleaning of the placement table 12, ensuring the cleaning effect, and improving the cleaning efficiency.

[0026] Compared with the prior art, the device for testing the compressive strength of concrete test blocks provided in this embodiment drives the push plate 50 to push the concrete fragments through the first telescopic member 51, moving in the direction close to the swing plate 60 until the concrete fragments push the swing plate 60 to swing vertically to avoid the concrete fragments, so that they fall into the collection box pre-placed outside the placement table 12. While the push plate 50 pushes the concrete fragments, the cleaning member 80 follows behind to rub the remaining concrete residues on the placement table 12, realizing the rapid cleaning of the placement table 12 and improving the cleaning efficiency.

[0027] In a possible implementation manner, the above-mentioned cleaning member 80 adopts the structure as shown in Figure 1 See Figure 1 , the cleaning member 80 includes a connecting plate 81 and a sponge wipe 82. The connecting plate 81 is connected to the outer side wall of the push plate 50 and extends along the interval direction of the two baffles 40; the sponge wipe 82 is connected to the bottom of the connecting plate 81 and extends along the length direction of the connecting plate 81.

[0028] Specifically, the sponge wipe 82 has a certain flexible deformation ability and can be in close contact with the top surface of the placement table 12, thereby thoroughly cleaning the concrete residues on the placement table 12 and improving the cleaning effect.

[0029] In some embodiments, see Figure 1 and Figure 2 , a water supply member 90 connected to the connecting plate 81 is provided on the workbench 10. The water supply member 90 includes a water tank 92 and a hose 91. The water tank 92 is arranged on the top of the workbench 10; one end of the hose 91 is connected to the top of the water tank 92 and the other end is connected to the connecting plate 81. The hose 91 penetrates through the connecting plate 81 in the up and down direction, and a water pump 911 is provided on the hose 91.

[0030] Specifically, the hose 91 is reserved with an appropriate length to facilitate adapting to the movement of the cleaning member 80. When cleaning the placement table 12, the water pump 911 pumps out the water in the water tank 92 and releases it through the hose 91 onto the sponge scrubber 82. The water quickly spreads throughout the sponge scrubber 82, further improving the cleaning effect of the sponge scrubber 82 on the placement table 12. When the sponge scrubber 82 has a certain humidity, the water pump 911 is turned off to avoid leaving water stains on the placement table 12.

[0031] In a possible implementation manner, the above-mentioned rotating shaft 61 adopts the structure as shown in Figures 1 to 3 See Figures 1 to 3 . A torsion spring 62 is sleeved on the outer periphery of the rotating shaft 61. One end of the torsion spring 62 is connected to the swing plate 60, and the other end is connected to the baffle 40.

[0032] Specifically, when the push plate 50 is in an unused state, that is, when testing the concrete test block, the push plate 50, the two baffles 40, and the swing plate 60 are arranged in a rectangle above the placement table 12. When the pressing member 20 presses down the concrete test block, the concrete test block cracks and splashes. The push plate 50, the two baffles 40, and the swing plate 60 can effectively block the splashed fragments, and under the action of the torsion spring 62, the fragments are prevented from bouncing the swing plate 60 open, effectively ensuring the safety of the external staff.

[0033] In a possible implementation manner, the above-mentioned baffle 40 adopts the structure as shown in Figures 1 to 3 See Figures 1 to 3 . An installation seat 41 is provided on the outer side wall of the baffle 40 close to the swing plate 60. The installation seat 41 has an extension plate 42 that horizontally extends to the outside of the side edge of the baffle 40. The locking member 70 is arranged on the extension plate 42. The locking member 70 includes a sliding rod 71 and an elastic member 74. The sliding rod 71 penetrates through the extension plate 42 along the axial direction of the rotating shaft 61 and is slidably connected to the extension plate 42. One end of the sliding rod 71 close to the swing plate 60 is connected with a stop block 72, and the other end of the sliding rod 71 far from the swing plate 60 is connected with an abutting platform 73 for abutting and cooperating with the extension plate 42; the elastic member 74 is sleeved on the outer periphery of the sliding rod 71 and is located between the stop block 72 and the extension plate 42. The elastic member 74 can elastically push the stop block 72 to the outside of the swing plate 60 to limit the outward swing of the swing plate 60.

[0034] Specifically, when the elastic member 74 is in a natural state, the stop block 72 is on the outside of the swing plate 60, blocking the opening of the swing plate 60, avoiding the splashed concrete fragments during the test from bouncing the swing plate 60 open, and effectively ensuring the safety of the external staff.

[0035] When it is necessary to clean the concrete debris after the test is completed, the staff pulls the abutting table 73 outward, causing the stopper 72 to avoid the swing plate 60. Finally, the first telescopic member 51 drives the push plate 50 and the cleaning member 80 to clean the concrete debris and residues. After the cleaning is completed and the push plate 50 returns to the initial position, the abutting table 73 is released, and the elastic member 74 pushes the stopper 72 to continue to be limited outside the swing plate 60, improving the practicability.

[0036] In some embodiments, referring to Figure 2 and Figure 3 , an electromagnet 75 is provided on the top of the workbench 10 on the side of the abutting table 73 away from the extension plate 42. The electromagnet 75 can adsorb the abutting table 73 to cause the stopper 72 to avoid the swing plate 60.

[0037] Specifically, by turning on the electromagnet 75 to adsorb the abutting table 73, the stopper 72 is caused to avoid the swing plate 60, without human participation, realizing the automatic locking and unlocking of the locking member 70, and improving the practicability.

[0038] In a possible implementation manner, the above-mentioned pressing member 20 adopts the structure as shown in Figure 1 and Figure 2 , referring to Figure 1 and Figure 2 , the pressing member 20 includes a second telescopic member 21 and a pressing plate 22. The second telescopic member 21 is arranged on the bracket 11 in the vertical direction and is located above the placing table 12; the pressing plate 22 is connected to the lower end of the second telescopic member 21.

[0039] Specifically, a top plate is provided on the top of the bracket 11. The second telescopic member 21 penetrates through the top plate in the vertical direction and is connected to the top plate. The second telescopic member 21 is used to drive the pressing plate 22 to press the concrete test block, which can not only drive the pressing plate 22 to move up and down, but also provide sufficient pressure for the pressing plate 22 to press the concrete test block.

[0040] In some embodiments, referring to Figure 1 and Figure 2 , a pressure sensor 30 is provided at the bottom of the pressing plate 22, and a controller 31 and a display 32 electrically connected to the controller 31 are provided on one side of the workbench 10. The controller 31 is electrically connected to the pressure sensor 30.

[0041] Specifically, the display 32 is used to display the test data. The data is transmitted from the pressure sensor 30 to the controller 31 and is displayed on the display 32 after being processed by the controller 31, which can enable the staff to observe and record intuitively.

[0042] In a possible implementation manner, the above-mentioned swing plate 60 adopts the structure as shown in Figure 2 and Figure 3 , referring to Figure 2 and Figure 3A limit plate 63 extending horizontally to the outside of the side edge of the swing plate 60 is provided on the outer side wall of the swing plate 60 . The limit plate 63 is used to abut against the side edge of the baffle 40 to limit the swing amplitude of the swing plate 60 .

[0043] Specifically, after the push plate 50 pushes the concrete fragments to the outside of the placement table 12 and returns to the initial position, the swing plate 60 swings down due to its own gravity until the limit plate 63 contacts the side edge of the baffle 40, and then stops swinging, which can limit the repeated shaking of the swing plate 60 when it swings down.

[0044] Furthermore, the limit plate 63 can be used in conjunction with the torsion spring 62 to fit the limit plate 63 to the side edge of the baffle 40 and ensure that the plate surface of the swing plate 60 is in a vertical direction in this state, thereby shielding the flying gravel with the maximum area.

[0045] Furthermore, the limiting plate 63 can be used in conjunction with the locking member 70 and the torsion spring 62 .

[0046] In a possible implementation, the workbench 10 is implemented as follows: Figure 1 and Figure 2 The structure shown, see Figure 1 and Figure 2 A material guide plate 13 is provided on the top of the workbench 10. The material guide plate 13 is located on the side of the placement table 12 away from the first telescopic member 51. The material guide plate 13 extends outward and downward in an inclined manner. A receiving box 14 is provided on one side of the workbench 10 and is located below the material guide plate 13 and is used to receive concrete fragments on the material guide plate 13.

[0047] Specifically, the guide plate 13 is used to guide the concrete fragments pushed out by the push plate 50 into the receiving box 14, thereby preventing the cleaned concrete fragments from scattering all over the workbench 10 and ensuring the cleaning effect.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
