Description
Technical Field
[0001] This application relates to the field of concrete testing technology, specifically a concrete quality testing device for engineering supervision. Background Technology
[0002] Concrete is an indispensable material in construction projects, and its quality is directly related to the safety and durability of buildings. Before concrete is put into use, it is necessary to test its strength, impermeability, durability and other indicators.
[0003] However, most existing concrete quality testing devices suffer from low testing efficiency, complex operation, and inability to perform multiple tests simultaneously, which increases testing costs. Utility Model Content
[0004] To address the shortcomings of existing technologies, this application provides a concrete quality testing device for engineering supervision, which has advantages such as improved testing efficiency. It solves the problems of low testing efficiency, complex operation, and inability to perform multiple tests simultaneously, which increase testing costs, that exist in most existing concrete quality testing devices.
[0005] To achieve the above objectives, this application provides the following technical solution: a concrete quality testing device for engineering supervision, comprising a base, a support plate fixedly connected to the upper end of the base, four electric push rods arranged in a rectangular array fixedly connected to the upper end of the support plate, clamps fixedly connected to the telescopic ends of the four electric push rods in pairs, a baffle fixedly connected to one side of the upper end of the support plate, four hydraulic rods arranged in a linear array fixedly connected to the upper end of the support plate, a lifting plate fixedly connected to the telescopic ends of the four hydraulic rods, a testing bucket fixedly connected to the bottom end of the lifting plate, two mounting seats arranged in a mirror distribution fixedly connected to the bottom end of the outer wall of the testing bucket, a testing head fixedly connected inside each of the two mounting seats, and a concrete hardness tester fixedly connected to one side of the upper end of the lifting plate.
[0006] The above scheme utilizes a support plate with four electrically driven actuators arranged in a rectangular array. The telescopic ends of these actuators connect to clamping plates, and together with a baffle on one side, effectively clamp and fix the concrete specimens, ensuring specimen stability during testing and preventing errors caused by shaking. This provides a fundamental guarantee for accurate testing. Effective clamping is achieved by adjusting the telescopic range of the actuators, eliminating the need for frequent replacement of clamping components and improving the applicability and efficiency of the device. Four hydraulic rods arranged in a linear array are located at the upper part of the support plate, with their telescopic ends connected to a lifting plate. The bottom of the lifting plate connects to a testing bucket, enabling the lifting and lowering of the testing bucket for convenient impermeability testing of the concrete specimens. Two testing heads are located at the bottom of the outer wall of the testing bucket, connecting to a concrete hardness tester, allowing direct hardness testing of the concrete specimens and obtaining accurate hardness data. This provides an important basis for concrete quality assessment. The use of electrically driven actuators and hydraulic rods reduces manual operation, minimizes the impact of human factors on the testing process, and improves the level of automation in the testing.
[0007] Furthermore, each of the two detection heads is fixedly connected to a connecting wire at its upper end, and the end of the two connecting wires away from the detection head passes through the lifting plate and is fixedly connected to the concrete hardness tester.
[0008] With the above solution, the detection head is directly and fixedly connected to the concrete hardness tester via a connecting cable, ensuring the continuity of signal transmission during the testing process and ensuring the accurate acquisition of hardness test data.
[0009] Furthermore, a water inlet pipe is fixedly connected inside the lifting plate, the bottom end of the water inlet pipe extends into the inside of the detection barrel, and a valve is fixedly sleeved on the outer wall of the water inlet pipe.
[0010] With the above scheme, the bottom end of the water inlet pipe extends into the inside of the test bucket, allowing water to be injected into the test bucket for concrete impermeability testing. A shut-off device is also provided for the water inlet pipe; after water injection is completed, closing the valve can prevent pressure leakage inside the test bucket.
[0011] Furthermore, an air inlet pipe is fixedly connected inside the lifting plate, and an air pressure pump is fixedly connected to the upper end of the lifting plate. The output end of the air pressure pump is fixedly connected to the air inlet pipe, and the bottom end of the air inlet pipe extends into the inside of the detection barrel.
[0012] The above method connects the air pump to the test chamber via an air inlet pipe, allowing it to inject gas into the test chamber and apply pressure, thereby simulating the use of concrete under different pressure environments.
[0013] Furthermore, a scale is provided on one side of the outer wall of the testing barrel.
[0014] With the above method, during the impermeability test, the scale on the outer wall of the test tank allows the operator to intuitively and quickly read the height of the water or liquid level inside the test tank. By observing the change of liquid level over time, relevant data can be recorded.
[0015] Furthermore, the support plate has a through groove inside, the base has a sliding groove inside, and a water collection tank is slidably arranged inside the sliding groove.
[0016] With the above solution, during the concrete quality testing process, when conducting impermeability testing, water may seep out from the bottom of the concrete specimen. The through groove inside the support plate is connected to the sliding groove inside the base, and the seeping or overflowing liquid can flow into the water collection tank in the sliding groove through the through groove, realizing the centralized collection of waste liquid and avoiding the liquid from flowing randomly and polluting the working environment.
[0017] Furthermore, a sealing ring is fixedly connected to the bottom of the testing barrel.
[0018] Using the above method, a certain amount of water needs to be injected into the testing bucket during concrete impermeability testing. The sealing ring can effectively fill the gap between the bottom of the testing bucket and the concrete specimen.
[0019] Furthermore, the testing barrel is made of acrylic material.
[0020] The above method utilizes the high transparency of acrylic material, allowing operators to directly and clearly observe changes in the liquid level within the testing tank during the testing process, facilitating the recording of relevant data.
[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0022] This concrete quality testing device for engineering supervision features four electric actuators arranged in a rectangular array on a support plate. The telescopic ends of these actuators connect to clamping plates, and together with a baffle on one side, they effectively clamp and fix concrete specimens, ensuring stability during testing and preventing errors caused by shaking. This provides a fundamental guarantee for accurate testing. Effective clamping is achieved by adjusting the telescopic range of the electric actuators, eliminating the need for frequent replacement of clamping components and improving the device's applicability and efficiency. Four hydraulic rods arranged in a linear array are located at the upper part of the support plate, with their telescopic ends connected to a lifting plate. The bottom of the lifting plate connects to a testing bucket, enabling the bucket to be raised and lowered for convenient testing of the concrete specimens' impermeability.

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.

Each pair of electric push rods 3 has a clamping plate 4 fixedly connected to its telescopic end. A baffle 5 is fixedly connected to one side of the upper end of the support plate 2. By using the four electric push rods 3 arranged in a rectangular array on the support plate 2, with their telescopic ends connected to the clamping plate 4 and the baffle 5 on one side, the concrete specimen can be effectively clamped and fixed, ensuring the stability of the specimen during testing and avoiding testing errors caused by shaking. This provides a basic guarantee for accurate testing. The support plate 2 also has four electric push rods arranged in a straight line... The hydraulic rods 6 are arranged in an array. The telescopic ends of the four hydraulic rods 6 are fixedly connected to the lifting plates 7. The bottom of the lifting plates 7 is connected to the test barrel 8, which can realize the lifting and lowering operation of the test barrel 8. The bottom of the lifting plates 7 is fixedly connected to the test barrel 8. The bottom of the outer wall of the test barrel 8 is fixedly connected to two mounting seats 9 arranged in a mirror distribution. The test heads 10 are fixedly connected inside the two mounting seats 9. A concrete hardness tester 11 is fixedly connected to one side of the upper end of the lifting plates 7. The bottom of the outer wall of the test barrel 8 is equipped with two test heads 10, which are connected to the concrete hardness tester 11, so that the hardness of the concrete specimen can be directly tested to obtain accurate hardness data.
[0032] Please see Figure 1 , Figure 3 and Figure 4 Both detection heads 10 are fixedly connected to the upper ends of connecting wires 12. The ends of the two connecting wires 12 away from the detection heads 10 pass through the lifting plate 7 and are fixedly connected to the concrete hardness tester 11. The detection heads 10 and the concrete hardness tester 11 are directly fixedly connected through the connecting wires 12 to ensure the continuity of signal transmission during the testing process and to ensure the accurate acquisition of hardness test data. A water inlet pipe 13 is fixedly connected inside the lifting plate 7. The bottom end of the water inlet pipe 13 extends into the inside of the testing barrel 8. A valve 14 is fixedly fitted on the outer wall of the water inlet pipe 13. The bottom end of the water inlet pipe 13 extends into the inside of the testing barrel 8, allowing water to pass through the water inlet pipe 13. Water is injected into the test tank 8 to conduct concrete impermeability testing, and a shut-off device is provided for the water inlet pipe 13. After the water injection is completed, closing the valve 14 can prevent pressure leakage inside the test tank 8. An air inlet pipe 15 is fixedly connected inside the lifting plate 7, and an air pressure pump 16 is fixedly connected to the upper end of the lifting plate 7. The output end of the air pressure pump 16 is fixedly connected to the air inlet pipe 15, and the bottom end of the air inlet pipe 15 extends into the test tank 8. The air pressure pump 16 is connected to the test tank 8 through the air inlet pipe 15, which can inject gas into the test tank 8 and apply pressure, thereby simulating the use of concrete under different pressure environments.
[0033] Please see Figure 1 , Figure 3 and Figure 5The outer wall of the test tank 8 has a scale 17 on one side. During the impermeability test, the scale 17 on the outer wall of the test tank 8 allows the operator to intuitively and quickly read the water level or liquid level inside the test tank 8. By observing the change of liquid level over time, relevant data can be recorded. The support plate 2 has a through groove 18, and the base 1 has a sliding groove 19. A water collection tank 20 is slidably installed inside the sliding groove 19. During the concrete quality test, when conducting the impermeability test, water may seep out from the bottom of the concrete specimen. The through groove 18 inside the support plate 2 is connected to the sliding groove 19 inside the base 1. The seeping or overflowing liquid can flow through the channel 18 into the water collection tank 20 in the chute 19, realizing the centralized collection of waste liquid and avoiding the liquid from flowing randomly and polluting the working environment. The bottom of the test bucket 8 is fixedly connected with a sealing ring 21. When testing the concrete impermeability, a certain amount of water needs to be injected into the test bucket 8. The sealing ring 21 can effectively fill the gap between the bottom of the test bucket 8 and the concrete specimen. The test bucket 8 is made of acrylic material. Acrylic material has high transparency, and the operator can directly and clearly observe the changes in liquid level in the test bucket 8 during the test, which is convenient for recording relevant data.
[0034] In this embodiment, the concrete quality testing device for engineering supervision uses a support plate 2 with four electric push rods 3 arranged in a rectangular array. The telescopic ends of these push rods are connected to clamping plates 4, and together with a baffle 5 on one side, they can effectively clamp and fix the concrete specimens, ensuring specimen stability during testing and avoiding testing errors caused by shaking. This provides a fundamental guarantee for accurate testing. Effective clamping is achieved by adjusting the telescopic degree of the electric push rods 3, eliminating the need for frequent replacement of clamping components and improving the applicability and efficiency of the device. The upper end of the support plate 2 is equipped with four hydraulic rods 6 arranged in a linear array, with their telescopic ends connected to lifting plates 7. The bottom end of the lifting plates 7 is connected to a testing bucket 8, enabling the lifting and lowering of the testing bucket 8 for convenient testing of the concrete specimens' impermeability. Two testing heads 10 are installed at the bottom of the outer wall of the testing bucket 8, connected to a concrete hardness tester 11, allowing direct hardness testing of the concrete specimens and obtaining accurate hardness data, providing an important basis for concrete quality assessment. The use of electric push rods 3 and hydraulic rods 6 reduces manual operation, minimizes the impact of human factors on the testing process, and improves the level of automation in the testing.
[0035] The working principle of the above embodiments is as follows:
[0036] The concrete specimen to be tested is placed on the support plate 2, between the clamping plates 4 connected in pairs by four electric push rods 3, and close to the baffle 5. The electric push rods 3 are activated, and the extension and retraction of the four electric push rods 3 are adjusted according to the size of the concrete specimen, so that the clamping plates 4 can effectively clamp and fix the concrete specimen, ensuring that the specimen remains stable during the testing process. The two detection heads 10 at the bottom of the outer wall of the testing bucket 8 are fixedly connected to the concrete hardness tester 11 at the upper end of the lifting plate 7 through the connecting line 12 to ensure the continuity of signal transmission. The four hydraulic rods 6 are activated, and their extension and retraction ends drive the lifting plate 7 to descend, thereby causing the testing bucket 8 to descend and press against the concrete specimen. The sealing ring 21 at the bottom of the testing bucket 8 can effectively fill the gap between the bottom of the testing bucket 8 and the concrete specimen to prevent water leakage. The concrete hardness tester 11 is activated, and the hardness of the concrete specimen is directly tested through the detection head 10 to obtain accurate hardness data. To provide important basis for concrete quality assessment, the valve 14 on the outer wall of the water inlet pipe 13 is opened, and a certain amount of water is injected into the test bucket 8 through the water inlet pipe 13 for concrete impermeability testing. The air pressure pump 16 is started, and the air pressure pump 16 injects gas into the test bucket 8 through the air inlet pipe 15 and applies pressure to simulate the water seepage of concrete under different pressure environments. The scale 17 on one side of the outer wall of the test bucket 8 is observed to read the water level in the test bucket 8. By observing the change of liquid level over time, relevant data are recorded to analyze the impermeability performance of concrete. During the test, water may seep out from the bottom of the concrete specimen. The seeping or overflowing liquid flows into the water collection tank 20 in the sliding groove 19 inside the base 1 through the through groove 18 inside the support plate 2, realizing the centralized collection of waste liquid and avoiding the liquid from flowing randomly and polluting the working environment. After the test is completed, the water collection tank 20 is pulled out from the sliding groove 19 for unified treatment of waste liquid.
