Description

Technical Field

[0001] This application relates to the field of measuring instrument technology, specifically a digital display concrete penetration resistance meter. Background Technology

[0002] The setting time of concrete is a key parameter affecting construction techniques and quality control. The initial setting time determines the workability of the concrete, while the final setting time marks the beginning of hardening and the acquisition of early strength. Concrete penetration resistance meters are typically used to test the setting time of concrete. When testing concrete samples, multiple penetration tests are usually performed on the same sample, with a certain interval between each test to avoid inaccurate results.

[0003] A prior patent (publication number: CN220154199U) discloses a concrete penetration resistance meter, which includes a platform connected by a bracket, a measuring component, and a pressure rod hinged to the bracket and the measuring component. A penetration component is connected below the measuring component. The penetration component includes a probe converter and three probes. The probe converter includes a first converter and a second converter. The second converter is connected below the first converter, and the probes are connected below the second converter. The first converter and the second converter are rotatably connected and equipped with a positioning structure. When the positioning structure positions the second converter, one of the probes is vertical and coaxially arranged with the measuring component. Existing concrete penetration resistance meters are all single-probe type, requiring repeated disassembly and reassembly to replace the penetration probes during the measurement process, which is very cumbersome. This application has the beneficial effect of simplifying the cement setting time measurement process and improving testing efficiency.

[0004] The above method cannot pinpoint the location of the sample penetration test when performing multiple penetration tests on concrete samples, which makes it impossible to control the spacing between multiple penetration tests and easily affects the accuracy of the sample test results. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a digital display concrete penetration resistance meter, which has the advantages of accurately locating the position of a concrete sample during multiple penetration tests. This allows for uniform multiple penetration tests of the concrete sample at equal intervals, preventing the spacing between multiple penetration tests from affecting the accuracy of the test results. This solves the problem that when performing multiple penetration tests on a concrete sample, it is impossible to locate the position of the sample penetration test, leading to an inability to control the spacing between multiple penetration tests and easily affecting the accuracy of the test results.

[0006] To achieve the goal of accurately positioning concrete samples during multiple penetration tests, and to uniformly perform multiple penetration tests on concrete samples at equal intervals, thus preventing the spacing between multiple penetration tests from affecting the accuracy of the concrete sample test results, this application provides the following technical solution: a digital display concrete penetration resistance meter, including a test base, a rotating shaft rotatably mounted on the top of the test base, a platform mounted on the top of the rotating shaft, a sample cylinder placed on the top of the platform, a penetration testing mechanism mounted above the sample cylinder, the penetration testing mechanism being mounted on the top of the test base via a support frame, a digital display mounted on the top of the test base, and a pin mounted on one side of the top of the platform via an adjustment component, the outer surface of the middle of the pin being inserted into the inner wall of a limiting hole, the limiting hole being formed on a limiting ring, and the limiting ring having multiple limiting holes arranged in a ring-shaped equidistant array.

[0007] The above solution allows for the fixing of the stage angle by inserting a pin into the limiting hole. Multiple limiting holes combined with the pin can fix the angle of the stage as it rotates the sample cylinder during multiple penetration tests, achieving precise positioning of the concrete sample during multiple penetration tests. This enables uniform multiple penetration tests on the concrete sample at equal intervals, preventing the spacing between multiple penetration tests from affecting the accuracy of the concrete sample test results.

[0008] Furthermore, the bottom end of the sample tube is inserted into the interior of the placement frame, which is located on top of the platform.

[0009] The above scheme uses a placement frame to fix the position of the sample tube on the top of the platform, allowing the penetration testing mechanism to be accurately inserted into the sample tube to test the concrete sample.

[0010] Furthermore, a limiting block is provided on one side of the bottom end of the sample cylinder. The limiting block is inserted into the inside of the limiting frame. The limiting frame is located on the top of the platform, and the inside of the limiting frame is connected to the inside of the placement frame.

[0011] The above scheme can fix the angle between the sample tube and the stage by inserting the limiting block into the inner wall of the limiting frame, thus preventing relative rotation between the sample tube and the stage and allowing the stage to stably drive the sample tube to rotate to the specified angle.

[0012] Furthermore, the outer surface of the middle part of the limiting ring is provided with multiple positioning rods through multiple fixing plates, and the multiple positioning rods are inserted into the interior of multiple positioning frames, which are located on the top of the test base.

[0013] The above solution allows the positioning rod to be inserted into the positioning frame to fix the limiting ring in the installation position at the top of the test base. At the same time, the positioning rod can be pulled out from the positioning frame to facilitate quick replacement of the limiting ring. The limiting ring with different numbers of limiting holes can be easily replaced according to the testing requirements.

[0014] Furthermore, the adjustment assembly includes a hinge frame, which is disposed on one side of the top of the shelf. A connecting plate is hinged to the hinge frame, and the inner wall of the end of the connecting plate away from the hinge frame is slidably connected to the outer surface of the middle part of the pin.

[0015] The above solution allows the connecting plate to be rotated by the hinge bracket, preventing the connecting plate from restricting the upward movement of the limit ring during replacement.

[0016] Furthermore, a baffle is provided at one end of the pin, and the diameter of the baffle is larger than the diameter of the pin.

[0017] The above solution prevents the pin from sliding down the inner wall of one end of the connecting plate, thus preventing the connecting plate from failing to cooperate with the pin and the limiting hole to fix the angle of the shelf.

[0018] Furthermore, a limiting rod is inserted into the inner wall of one side of the middle portion of the connecting plate, and the outer surface of the middle portion of the limiting rod is inserted into the inner wall of the middle portion of the support plate, which is located on one side of the top of the shelf.

[0019] The above solution uses a limiting rod inserted into the inner wall of one side of the connecting plate to cooperate with the support plate, which can fix the angle of the connecting plate and prevent the connecting plate from swinging when the pin is pulled out at one end of the inner wall. This improves the stability of the connecting plate when the pin is pulled out. By pulling the limiting rod out of the inner wall of one side of the connecting plate, the angle of the connecting plate can be fixed, allowing the connecting plate to be flipped smoothly.

[0020] Furthermore, the sample cylinder is made of stainless steel.

[0021] The above solution, using a stainless steel sample tube, can prevent the sample tube from corroding the concrete sample and improve the service life of the sample tube.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This digital concrete penetration resistance meter fixes the angle of the stage by inserting a pin into a limiting hole. Multiple limiting holes, in conjunction with the pin, fix the angle of the stage as it rotates the sample cylinder during multiple penetration tests. This allows for precise positioning of the concrete sample during multiple penetration tests, enabling uniform and equidistant penetration tests and preventing the spacing between tests from affecting the accuracy of the test results.

Detailed Implementation

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] Please see Figure 1 , Figure 2 and Figure 3This embodiment of a digital concrete penetration resistance meter includes a test base 1, a rotating shaft 2 rotatably mounted on the top of the test base 1, a platform 3 mounted on the top of the rotating shaft 2, a sample tube 4 placed on the top of the platform 3, a penetration detection mechanism 5 mounted above the sample tube 4, the penetration detection mechanism 5 being mounted on the top of the test base 1 via a support frame, a digital display 6 mounted on the top of the test base 1, and a pin 8 mounted on one side of the top of the platform 3 via an adjustment component 7, the outer surface of the middle part of the pin 8 being inserted into the inner wall of a limiting hole 9, the limiting hole 9 being opened on a limiting ring 10, and the limiting ring 10 having multiple limiting holes 9 arranged in a ring-shaped equidistant array.

[0033] Please see Figure 1 , Figure 2 and Figure 4 The bottom end of the sample tube 4 is inserted into the inside of the placement frame 11, which is set on the top of the platform 3. The placement frame 11 can fix the placement position of the sample tube 4 on the top of the platform 3, so that the penetration testing mechanism 5 can be accurately inserted into the sample tube 4 to test the concrete sample.

[0034] Please see Figure 1 , Figure 2 and Figure 4 A limiting block 13 is provided on one side of the bottom end of the sample tube 4. The limiting block 13 is inserted into the inside of the limiting frame 12. The limiting frame 12 is located on the top of the platform 3. The inside of the limiting frame 12 is connected to the inside of the placement frame 11. By inserting the limiting block 13 into the inner wall of the limiting frame 12, the angle between the sample tube 4 and the platform 3 can be fixed, preventing the sample tube 4 from rotating relative to the platform 3, so that the platform 3 can stably drive the sample tube 4 to rotate to the specified angle.

[0035] Please see Figure 1 , Figure 3 and Figure 4 Multiple positioning rods 14 are provided on the outer surface of the middle part of the limiting ring 10 through multiple fixing plates. The multiple positioning rods 14 are inserted into the interior of multiple positioning frames 15. The positioning frames 15 are set on the top of the test base 1. By inserting the positioning rods 14 into the interior of the positioning frames 15, the limiting ring 10 can be fixed in the installation position on the top of the test base 1. At the same time, the positioning rods 14 can be pulled out from the interior of the positioning frames 15 to facilitate quick replacement of the limiting ring 10. The limiting ring 10 with different numbers of limiting holes 9 can be easily replaced according to the testing requirements.

[0036] Please see Figure 1 , Figure 3 and Figure 5The adjustment component 7 includes a hinge frame 701, which is located on one side of the top of the shelf 3. A connecting plate 702 is hinged to the hinge frame 701. The inner wall of the end of the connecting plate 702 away from the hinge frame 701 is slidably connected to the outer surface of the middle part of the pin 8. The hinge frame 701 can drive the connecting plate 702 to flip, preventing the connecting plate 702 from restricting the upward movement of the limit ring 10 during replacement.

[0037] Please see Figure 1 , Figure 2 and Figure 3 A baffle 16 is provided at one end of the pin 8. The diameter of the baffle 16 is larger than the diameter of the pin 8. The baffle 16 is provided to prevent the pin 8 from sliding down from the inner wall of one end of the connecting plate 702, and to prevent the connecting plate 702 from being unable to cooperate with the pin 8 and the limiting hole 9 to fix the angle of the platform 3.

[0038] Please see Figure 1 , Figure 2 and Figure 3 A limiting rod 17 is inserted into the inner wall of one side of the middle portion of the connecting plate 702. The outer surface of the middle portion of the limiting rod 17 is inserted into the inner wall of the middle portion of the support plate 18. The support plate 18 is located on one side of the top of the shelf 3. By inserting the limiting rod 17 into the inner wall of one side of the middle portion of the connecting plate 702 in conjunction with the support plate 18, the angle of the connecting plate 702 can be fixed, preventing the connecting plate 702 from swinging when the pin 8 is pulled out from the inner wall of one end of the connecting plate 702. This improves the stability of the connecting plate 702 when the pin 8 is pulled out. By pulling the limiting rod 17 out from the inner wall of one side of the middle portion of the connecting plate 702, the fixing of the angle of the connecting plate 702 can be released, allowing the connecting plate 702 to be flipped smoothly.

[0039] Please see Figure 1 , Figure 2 and Figure 3 The sample cylinder 4 is made of stainless steel, which can prevent the sample cylinder 4 from corroding the concrete sample and improve the service life of the sample cylinder 4.

[0040] In this embodiment, a digital concrete penetration resistance meter can fix the angle of the platform 3 by inserting a pin 8 into a limiting hole 9. By using multiple limiting holes 9 in conjunction with the pin 8, the angle of the platform 3 and the sample cylinder 4 can be fixed when the sample is rotated during multiple penetration tests. This achieves precise positioning of the concrete sample during multiple penetration tests, and allows for uniform multiple penetration tests of the concrete sample at equal intervals, preventing the spacing between multiple penetration tests from affecting the accuracy of the concrete sample test results.

[0041] The working principle of the above embodiment is as follows: The sample tube 4 containing the concrete sample to be tested is placed on the top of the stage 3, and the bottom end of the sample tube 4 is inserted into the placement frame 11. The limiting block 13 is inserted into the limiting frame 12. The penetration testing mechanism 5 is operated to test the concrete sample in the sample tube 4. The test value will be displayed on the screen of the digital display 6. When multiple penetration tests of the concrete sample are required, the pin 8 is pulled out from the limiting hole 9 to release the fixation of the angle of the stage 3. The stage 3 is rotated so that the stage 3 rotates on the top of the test base 1 through the rotating shaft 2, driving the sample tube 4 to rotate until the pin 8 rotates to the top of the next limiting hole 9. The pin 8 is then inserted into the limiting hole 9 to fix the angle of the stage 3, thereby fixing the angle of the sample tube 4. The position of the concrete sample to be tested in the sample tube 4 is rotated to the penetration testing position. Below the testing mechanism 5, the penetrating testing mechanism 5 is operated to perform another penetration test on the concrete sample. The operation is repeated until multiple tests on the concrete sample are completed. When it is necessary to replace the limiting ring 10 with a different number of limiting holes 9 according to the testing requirements, the pin 8 is pulled out from the limiting hole 9 and the inner wall of one end of the connecting plate 702. The limiting rod 17 is pulled out from the inner wall of one side of the middle of the connecting plate 702 to release the restriction on the connecting plate 702. The connecting plate 702 is pushed to flip it upward through the hinge frame 701, so that the connecting plate 702 is moved away from the upward movement trajectory of the limiting ring 10. The limiting ring 10 is pulled upward to pull the positioning rod 14 out of the positioning frame 15. The limiting ring 10 is removed from the test base 1. The limiting ring 10 to be replaced is taken out. The limiting ring 10 is installed on the test base 1 through the positioning rod 14 and the positioning frame 15, thus completing the replacement of the limiting ring 10.
