Description

Technical Field

[0001] The present application relates to the technical field of concrete strength detection, and in particular to a concrete strength detection device. Background Art

[0002] Concrete is a general term for engineering composite materials that are made of aggregates bonded together by cementitious materials. The term concrete usually refers to cement as the cementitious material, sand and stone as aggregates, mixed with water in a certain proportion, and obtained by mixing. Cement concrete, also known as ordinary concrete, is widely used in civil engineering and requires a strength testing device after processing.

[0003] The patent, with the published authorization announcement number CN219065070U, describes a concrete testing device for strength testing, comprising a base, a lifting mechanism, and a cleaning mechanism. The base has a workbench at its upper end, a clamping mechanism corresponding to the workbench, and a cleaning mechanism at its upper end. The base also has symmetrical brackets, with support plates positioned between them. A connecting rod is positioned at the lower end of each support plate, and a pressure value display is positioned at the lower end of each connecting rod. When using this device, concrete is placed on the workbench, a first motor is activated to rotate a first threaded rod, and the first threaded rod drives two sliders toward each other, thereby driving the clamping plates to clamp and secure the concrete, preventing movement of the concrete during testing and resulting in inaccurate test data.

[0004] When the above device is implemented, it is unable to protect the debris generated during the test, which causes it to splash randomly, affecting the cleanliness of the workplace. At the same time, if it accidentally enters the eyes of the workers, it will cause them discomfort. It is also inconvenient to observe the state of the debris falling during the test. At the same time, the above device can only test one piece of concrete and needs to be replaced after the test, which is inefficient. Utility Model Content

The power output shaft of the cylinder 2 16 is fixedly connected to a connecting plate 17, and a moving bar 18 is fixedly installed on the outer side of the connecting plate 17.

[0031] See Figure 1 and Figure 2 Four reinforcement rods 2 are symmetrically fixed on the outside of the frame 1. The outer edges of the frame 1 and the four reinforcement rods 2 are coated with a galvanized layer, so that the overall structure of the frame 1 can be reinforced to ensure the firmness of the frame 1. The galvanized layer can also increase the aesthetics and corrosion resistance of the frame 1 and the reinforcement rods 2.

[0032] See Figure 2 Both bases 5 are made of silicone, and the top of the base 5 is provided with anti-slip grooves, so that the concrete to be tested can be placed on the top of the base 5. The anti-slip grooves increase the friction, thereby ensuring that the concrete will not shake randomly when the pressing plate 14 squeezes the concrete, thereby ensuring the uniformity of the concrete when it is subjected to force.

[0033] See Figure 4 A through hole is formed on the outer side of the rubber seat 7, and a bolt 9 is threadedly connected to the inner wall of the through hole, so that after the bolt 9 is threadedly connected to the inner wall of the through hole, the opening 8 can be tightened, and the round rod 10 can be stably positioned on the inner wall of the rubber seat 7. After removing the bolt 9, the rubber seat 7 can be opened using the opening 8, and then the round rod 10 can be taken out from the inner wall of the rubber seat 7.

[0034] See Figure 3 and Figure 4 Four limit rods 15 are symmetrically fixedly connected to the top of the pressure plate 14, and the four limit rods 15 are slidably connected to the inner wall of the slide 12, so that the pressure plate 14 and the output shaft of the cylinder 13 can be limited when moving up and down, ensuring that they are in a vertical state and move up and down stably, thereby ensuring that they will not deviate from position and shake.

[0035] See Figure 4 The top of the moving bar 18 is fixedly connected to the slide 12 by a number of parallel bolts 9, so that the moving bar 18 and the slide 12 can be fixedly connected, and then the cylinder 2 16 drives the connecting plate 17 to drive the moving bar 18 to move, and the slide 12 can be moved to adjust the position of the pressing plate 14, so that the strength test of the concrete placed in the inner cavity of the two box bodies 4 can be realized.

[0036] See Figure 4 A fixing plate 19 is fixedly installed on the outer side of the frame 1, and the outer side of the fixing plate 19 is fixedly connected to the side of the cylinder 2 16 away from the output end, so that the tail of the cylinder 2 16 and the frame 1 are firmly connected by the fixing plate 19, ensuring that the cylinder 2 16 will not shake between the top of the frame 1 during operation, thereby ensuring its stability during operation.

[0037] See Figure 4 A positioning plate 20 is fixedly installed on the top of the square bar 6 of the frame 1. The output end of the cylinder 2 16 is slidably connected to the inner wall of the positioning plate 20. The side of the positioning plate 20 away from the connecting plate 17 is fixedly connected to the outer wall of the cylinder 2 16, so that the side of the cylinder 2 16 away from the fixed plate 19 can be positioned by the positioning plate 20, further improving the stability of the cylinder 2 16, and ensuring that the output end of the cylinder 2 16 will not interfere with the positioning plate 20 during extension and retraction.

[0038] Working principle: When using the device, the device can be placed at the place of use first, and then two pieces of tested concrete can be placed at the top position of the inner base 5 of the two box bodies 4, and then the cylinder 13 can be driven to drive the pressure plate 14 to move downward, apply pressure to the concrete, and test its strength. Then the cylinder 2 16 can be driven to operate and use the connecting plate 17 to drive the moving bar 18 and the slide plate 12 to slide, thereby driving the slider 11 to slide on the outer edge of the round rod 10 until the pressure plate 14 is adjusted to the upper position of the other concrete, and then the cylinder 13 can be driven again to drive the pressure plate 14 to move downward, apply pressure to the other piece of concrete, and test its strength. The box body 4 can ensure that the slag and debris generated when squeezing the concrete block will not splash or fall at will, which is convenient for ensuring the cleanliness of the workplace. At the same time, after removing the bolts 9 used to fasten the rubber seat 7 and the slide plate 12, the round rod 10 and the rubber seat 7 can be separated, and the slide plate 12 can be separated from the moving bar 18, and then the slide plate 12 and the pressure plate 14 can be taken out to the outside, which is convenient for disassembly, replacement and maintenance, thereby improving convenience.
