Technical Field

[0001] This utility model relates to the field of concrete testing devices, and in particular to a concrete strength testing device. Background Technology

[0002] As one of the main materials used in construction, concrete's strength directly determines a building's load-bearing capacity and stability. Concrete strength testing allows for an accurate assessment of its load-bearing capacity, ensuring that buildings meet safety requirements during design and construction. Insufficient concrete strength can lead to building damage or collapse; therefore, testing concrete strength is a crucial step in ensuring building safety.

[0003] Existing concrete strength testing devices have the following shortcomings: 1. The testing point location is limited, allowing only localized force testing of the concrete, resulting in a limited testing range that cannot meet diverse testing needs. 2. Testing is either sealed, making it inconvenient to monitor the testing progress, or it is open, generating dust and debris that can easily cause environmental pollution and safety hazards. Utility Model Content

[0004] To address the problems existing in the background technology, a concrete strength testing device is proposed, comprising a testing platform, a lifting seat 1, a testing component, a sealing cover 1, and a sealing cover 2. A rotatable support is installed in the center of the testing platform, with sample limiting frames on both sides. The lifting seat 1 is located at the top of the support, and its position alternates with the two sets of sample limiting frames as the support rotates. A semi-enclosed sealing cover 1 is installed on its outer side. The testing component is located at the bottom of the lifting seat 1, including a centrally located testing element 1 and a movable and rotatable testing element 2 on the outer periphery. The sealing cover 2 is semi-enclosed on one side of the sample limiting frames, and it extends through the testing platform by rising, simultaneously connecting with the descending sealing cover 1 to form a sealing cover structure surrounding the sample limiting frames. A dust collection component is installed on the sealing cover 2.

[0005] Preferably, the bracket is an inverted L-shaped structure, with a motor mount for drive selection at the bottom of the vertical section and a cylinder for driving the lifting seat to rise and fall in the horizontal section.

[0006] Preferably, the detection assembly includes a mounting plate located at the center of the lifting base and a motor arranged around the mounting plate; the main shaft of the motor is connected to one end of the detection frame, so that the detection frame rotates along the outer wall of the mounting plate with the connection point as the center; the detection frame is provided with a mounting groove; a lead screw driven by a motor is provided in the mounting groove; the top of the moving block extends into the mounting groove and is threadedly connected to the lead screw to achieve horizontal movement along the mounting groove; a detection element is arranged on the moving block; a detection element is arranged on the mounting plate.

[0007] Preferably, the lifting seat is provided with an arc-shaped slide rail; the testing frame is provided with a guide block that cooperates with the slide rail.

[0008] Preferably, the first detection component includes a second cylinder located on the moving block; the telescopic rod of the second cylinder faces downward and is equipped with a detachable striking device; the second detection component has the same structure as the first detection component.

[0009] Preferably, sliding grooves are provided on both sides of the mounting groove; a slider that cooperates with the sliding groove is provided on the cylinder body of cylinder two.

[0010] Preferably, the testing platform is provided with a through groove for the lifting and lowering of the sealing cover 2, and a support frame is provided at the bottom of the testing platform; a lead screw 2 driven to rotate by a motor 3 is provided on the support frame; a lifting seat 2 is provided on the lead screw 2 and threadedly connected thereto; the sealing cover 2 is provided on the lifting seat 2.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects:

[0014] 1. The motor base and cylinder one are configured to drive each other. On one hand, this allows the lifting platform one to rotate, switching between different work positions to process concrete samples within the sample limiting frame in turn, ensuring a continuous and alternating testing process and improving efficiency. On the other hand, it allows the lifting platform to lower, making the testing height of test piece one and test piece two adjustable. Test piece one performs strength testing on the outer perimeter of the sample through movement and rotation. Test piece two performs strength testing on the middle of the sample. The large testing range and flexible testing positions can meet diverse testing needs.

[0015] 2. A sample limiting frame is set up to limit the test sample. A sealing cover 1 is set up to rise and rotate synchronously with the lifting seat 1, and a sealing cover 2 is set up to rise and fall on the test platform. Sealing cover 1 and sealing cover 2 can be connected to form a sealing cover structure that surrounds the sample limiting frame and the lifting seat 1, thereby solving the problems of contamination and safety hazards during the test. Moreover, one side of the sealing cover structure can be opened at any time during the test, so that the test progress can be directly viewed.

[0016] Third, a dust collection device is installed on the second sealing cover to absorb and transfer the dust and debris flying during the concrete impact process into the dust collection box. This reduces dust flying after the test and also facilitates the observation of the test results. Attached Figure Description

[0023] Example 1: This utility model proposes a concrete strength testing device, such as... Figures 1-2 It includes a testing platform 1, a lifting seat 3, and a testing component 5. A rotatable support 2 is provided in the middle of the testing platform 1, and sample limiting frames 6 are provided on both sides. The lifting seat 3 is located on top of the support 2 and rotates with the support 2, alternately facing the two sets of sample limiting frames 6. The testing component 5 is located at the bottom of the lifting seat 3 and includes a centrally located testing element 510 and a movable and rotatable testing element 509 located on the outer periphery.

[0024] It should be further explained that the bracket 2 is an inverted L-shaped structure. The bottom of the vertical section is equipped with a motor base 10 for drive selection, and the horizontal section is equipped with a cylinder 8 for driving the lifting seat 3 to rise and fall. Driven by the motor base 10 and the cylinder 8, the lifting seat 3 is rotated to switch between different work positions and process the concrete samples in the sample limiting frame 6 in turn. On the other hand, the lifting seat 3 is lowered to form a sealed cover structure. The detection component 5 moves into the sealed cover structure for detection, reducing the flying of dust and debris.

[0025] Further explanation is needed, such as Figure 3As shown, the detection assembly 5 includes a mounting plate 508 located at the center of the lifting base 3 and a motor 501 arranged around the mounting plate 508. The main shaft of the motor 501 is connected to one end of the detection frame 502, causing the detection frame 502 to rotate around the connection point along the outer wall of the mounting plate 508. The detection frame 502 is provided with a mounting groove 503. A lead screw 504 driven to rotate by the motor 504 is installed in the mounting groove 503. The top of the moving block 505 extends into the mounting groove 503 and is threadedly connected to the lead screw 504, enabling it to move horizontally along the mounting groove 503. Detection element 510 is arranged on the moving block 505. Detection element 509 is arranged on the mounting plate 508. The rotation of the detection frame 502 drives the detection element 510 to rotate synchronously, and the sliding of the moving block 505 drives the detection element 510 to move synchronously. The detection element 510 detects the outer periphery of the concrete block. Detection element 509 detects the center of the concrete.

[0026] Further explanation is needed, such as Figures 3-4 As shown, the lifting seat 3 is provided with an arc-shaped slide rail 301; the testing frame 502 is provided with a guide block 511 that cooperates with the slide rail 301; the guide block 511 moves on the slide rail 301 to guide the sliding of the testing frame 502, making its movement more stable.

[0027] Further explanation is needed, such as Figures 3-4 As shown, the first test piece 510 includes a second cylinder 506 located on the moving block 505; the telescopic rod of the second cylinder 506 faces downward and is equipped with a detachable striking device 507; the second test piece 509 has the same structure as the first test piece 510; the movement of the mating position is achieved by the rapid striking of the striking device 507, so as to realize the strength test of different positions of the concrete block sample.

[0028] Further explanation is needed, such as Figures 3-4 As shown, sliding grooves are provided on both sides of the mounting groove 503; a slider that mates with the sliding groove is provided on the cylinder body of cylinder two 506. Through the cooperation of the slider and the sliding groove, cylinder two 506 can move in the horizontal direction.

[0029] Example 2: This example is based on a concrete strength testing device proposed in Example 1, such as... Figure 1 As shown, a semi-enclosed sealing cover 4 is provided on the outside of the lifting seat 3; the sealing cover 7 is semi-enclosed on one side of the sample limiting frame 6, and passes through the detection stage 1 by rising, and at the same time connects with the descending sealing cover 4 to form a sealing cover structure that surrounds the sample limiting frame 6.

[0030] Further explanation is needed, such as Figure 5As shown, the testing table 1 is provided with a through groove 101 for the lifting and lowering of the sealing cover 7, and a support frame 12 is provided at the bottom of the testing table 1; a lead screw 13 driven to rotate by a motor is provided on the support frame 12; a lifting seat 11 threadedly connected to the lead screw 13 is provided on the lead screw 13; the sealing cover 7 is placed on the lifting seat 11, and the rotation of the lead screw 13 can drive the sealing cover 7 to rise and fall synchronously with the lifting seat 11 within the through groove 101.

[0031] It should be further explained that the through groove 101 is U-shaped and is set along the edge of the sample limiting frame 6; the sealing cover 2 7 and the sealing cover 1 4 are U-shaped structures of the same size, and an electromagnetic structure is set at the joint. The sealing cover structure formed by electromagnetic attraction matches the size and shape of the sample limiting frame 6; when strength testing is carried out, dust and debris will not fly or overflow, reducing environmental pollution and safety hazards.

[0032] It should be further noted that the sample limiting frame 6 can be set to a size that matches the size of the test block.

[0033] Example 3: Based on the concrete strength testing device proposed in Example 2, this example further proposes that a dust collection component be installed on the sealing cover 7. For example... Figure 5 As shown, a collection port is provided on the top of the sealing cover 7; a protective net 701 is provided on the collection port; the dust collection component includes a collection cover 14 that is always located above the test platform 1 and installed opposite to the protective net 701, a dust collection box 9 with a dust collection device located at the bottom of the test platform 1, and a telescopic dust collection pipe connecting the dust collection box 9 and the collection cover 14.

[0034] When the second sealing cover 7 rises to magnetically attract the first sealing cover 4, the collection cover 14 moves upwards simultaneously. During the testing process, the airborne dust and debris are adsorbed and transferred into the dust collection box 9. After the second sealing cover 7 and the first sealing cover 4 are subsequently removed, there will still be no dust problem, and the test results can be viewed intuitively.

[0035] The working principle of the above-mentioned concrete strength testing device is as follows: Samples are taken at the pouring site, and test blocks (150mm cubes) are prepared according to standard methods and cured for 28 days under standard conditions (20±2°C, humidity ≥95%). The sample is placed within the sample limiting frame 6. At this time, the sealing cover 4 and the sealing cover 7 are separated, one above the other. After the sample is placed, the rotation of the lead screw 13 causes the sealing cover 7 to rise synchronously with the lifting seat 11 within the through groove 101. Driven by the motor base 10 and the cylinder 8, the lifting seat 3 rotates, switching to the position directly above the corresponding sample limiting frame 6, while simultaneously lowering the lifting seat 3. The sealing cover 4 then descends synchronously until it magnetically attracts the sealing cover 7, forming a sealed cover structure. Next, the rotation of the testing frame 502 and the sliding of the moving block 505 cause the testing piece 510 to move synchronously. The testing piece 510 tests the outer periphery of the concrete block. The testing piece 509 tests the center of the concrete. Dust and debris generated during concrete impact are absorbed and transferred to the dust collection box 9. During testing, the sealing cover 7 can be lowered to directly observe the progress without interrupting the process. Once one side is inspected, the sealing cover structure disassembles. The lifting seat 3 rotates, switching to position directly above the sample limiting frame 6 on the other side. Workers pre-place the test samples, ensuring continuous and alternating testing on both sides.

[0036] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
