Description

Technical Field

[0001] This application relates to the field of concrete testing technology, and in particular to a concrete quality testing device based on building engineering. Background Technology

[0002] The term "concrete" usually refers to cement concrete, which is made by mixing cement as a binder, sand and gravel as aggregates, and water in a certain proportion. It is also called ordinary concrete and is widely used in engineering. However, due to differences in the mixing ratio of cement and sand and the quality of materials, the strength and adhesion of concrete vary, thus requiring concrete testing.

[0003] A search revealed that patent CN220794917U discloses a concrete quality testing device, including a base plate and an installation mechanism mounted on the base plate. The installation mechanism includes a protective component and a cleaning component. The protective component includes a fixed bracket and a first motor. This invention uses the first motor to drive a first threaded rod to rotate, enabling a first support rod to move up and down on the outer surface of the threaded rod. This allows a connecting rod connected to the lower surface of the first support rod to move a protective baffle up and down, thus preventing concrete debris from splashing during concrete impact and improving safety. Furthermore, by rotating a second threaded rod and under the extension and retraction limit of a telescopic rod, a clamping plate can be moved to extend and retract, allowing adjustment of the clamping plate according to the size of the concrete. This effectively fixes the concrete, improves the stability of concrete quality testing, and increases efficiency.

[0004] Although the device can clean the concrete debris on the placement plate, it cannot clean the dust generated inside the protective baffle. During the testing process, the concrete debris will generate dust after being crushed by impact. The dust will adhere to the inner wall of the protective baffle and the surface of the pressure sensor, thus affecting the test results. Summary of the Invention

[0005] To address the problems mentioned in the background art, this application provides a concrete quality testing device based on building engineering.

[0006] The concrete quality testing device based on building engineering provided in this application adopts the following technical solution:

[0007] A concrete quality testing device for building engineering includes a testing platform. The top of the testing platform is provided with two symmetrical mounting frames, and a support plate is fixedly connected between the two mounting frames. An electric telescopic rod is installed on the top of the support plate, and a testing mechanism is installed at the bottom of one end of the electric telescopic rod. The top of the testing platform is also provided with a placement plate, and a cleaning mechanism is installed on the top of the placement plate. An opening is provided at one edge of the placement plate on the top of the testing platform.

[0008] Preferably, the detection mechanism includes a U-shaped connecting frame installed at one end of the electric telescopic rod, a protective cover is provided at the bottom of the U-shaped connecting frame, and a hydraulic cylinder is installed at the top of the protective cover inside the U-shaped connecting frame.

[0009] Preferably, the output end of the hydraulic cylinder is inserted into the interior of the protective cover, and a pressure plate is also installed at the output end of the hydraulic cylinder, with a pressure sensor installed on the top of the pressure plate.

[0010] Preferably, two symmetrical first sliding blocks are also installed on the side walls of both ends of the protective cover. One end of each of the two first sliding blocks is slidably mounted on a first sliding rod fixedly connected between the bottom of the support plate and the top of the testing platform. The bottom of one end of each first sliding block is also connected to one end of a buffer spring, and the other end of the buffer spring is connected to the top of the testing platform.

[0011] Preferably, two symmetrical first sliding blocks are also installed on the side walls of both ends of the protective cover. One end of each of the two first sliding blocks is slidably mounted on a first sliding rod fixedly connected between the bottom of the support plate and the top of the testing platform. The bottom of one end of each first sliding block is also connected to one end of a buffer spring, and the other end of the buffer spring is connected to the top of the testing platform.

[0012] Preferably, the cleaning mechanism includes two symmetrical fixed frames installed at the top edges of the placement plate, one of which has a second sliding rod fixedly connected inside, and the other fixed frame has a lead screw rotatably installed inside.

[0013] Preferably, symmetrical second sliding blocks are adapted to be installed on the second slide rod and the lead screw, and a cleaning brush is connected between the second sliding blocks. One end of the lead screw is also connected to a transmission component that drives the cleaning brush to move back and forth for cleaning.

[0014] Preferably, the transmission assembly includes a second transmission wheel installed at one end of a lead screw, the second transmission wheel being fitted with one end of a transmission belt, the other end of the transmission belt being fitted with a first transmission wheel, the first transmission wheel being fixedly installed at one end of a transmission shaft located at the output end of a servo motor, and the servo motor being fixedly installed at the edge of the top of the testing table near the placement plate.

[0015] In summary, this application includes the following beneficial technical effects:

[0016] This utility model utilizes a dust-collecting component located on the back of the protective cover. Through the action of a vacuum cleaner and a vacuum hose, it effectively collects dust generated inside the protective cover during concrete testing and transports it to a collection box. This prevents dust generated after concrete breakage from adhering to the inside of the protective cover and the surface of the pressure sensor. Simultaneously, in conjunction with a cleaning mechanism, a servo motor drives a lead screw to rotate through a first transmission wheel, a transmission belt, and a second transmission wheel. This causes the cleaning brush to move back and forth to clean the concrete debris on the surface of the placement plate, thereby improving the cleaning effect.

[0017] This utility model uses an electric telescopic rod to move the protective cover connected to the bottom of the U-shaped connecting frame downwards to cover the concrete to be tested, preventing the concrete from shattering and splashing during testing, thus improving safety. At the same time, the first sliding blocks set at both ends of the protective cover slide downwards along the first sliding rod, and under the action of the buffer spring, they prevent the protective cover from falling too fast and colliding with the placement plate, thereby playing a certain buffering role.

[0023] The following is in conjunction with the appendix Figure 1 —4. This application will be described in further detail.

[0024] This application discloses a concrete quality testing device based on building engineering, including a testing platform 1. The top of the testing platform 1 is provided with two symmetrical mounting frames 2, and a support plate 3 is fixedly connected between the two mounting frames 2. An electric telescopic rod 4 is installed on the top of the support plate 3, and a testing mechanism is installed at the bottom of one end of the electric telescopic rod 4. The top of the testing platform 1 is also provided with a placement plate 5, and a cleaning mechanism is provided on the top of the placement plate 5. An opening is opened at one edge of the placement plate 5 on the top of the testing platform 1.

[0025] refer to Figure 1 and Figure 2 The testing mechanism includes a U-shaped connecting frame 6 installed at one end of the electric telescopic rod 4. A protective cover 7 is provided at the bottom of the U-shaped connecting frame 6. A hydraulic cylinder 8 is installed inside the U-shaped connecting frame 6 at the top of the protective cover 7. The output end of the hydraulic cylinder 8 enters the interior of the protective cover 7, and a pressure plate 9 is also installed at the output end of the hydraulic cylinder 8. A pressure sensor is installed on the top of the pressure plate 9. Two symmetrical first sliding blocks 10 are also installed on the side walls of both ends of the protective cover 7. One end of the two first sliding blocks 10 is slidably installed on a first sliding rod 11 fixedly connected between the bottom of the support plate 3 and the top of the testing platform 1. The bottom of one end of the first sliding block 10 is also connected to one end of a buffer spring 12. The other end of the buffer spring 12 is connected to the top of the testing platform 1. Two symmetrical first sliding blocks 10 are also installed on the side walls of both ends of the protective cover 7. One end of the two first sliding blocks 10 is slidably installed on the support plate 3. On the first sliding rod 11, which is fixedly connected between the bottom of the 3rd floor and the top of the test platform 1, one end of the bottom of the first sliding block 10 is also connected to one end of the buffer spring 12. The other end of the buffer spring 12 is connected to the top of the test platform 1. More specifically, when testing the concrete, the electric telescopic rod 4 is driven to move the protective cover 7 connected to the bottom of the U-shaped connecting frame 6 downward. The first sliding blocks 10 set on the side walls at both ends of the protective cover 7 slide downward along the first sliding rod 11 and squeeze the buffer spring 12, so that the protective cover 7 avoids collision with the placement plate 5 during the downward movement. Then, the hydraulic cylinder 8 is driven to move the pressure plate 9 downward to perform a compression test on the concrete. When the concrete is squeezed and crushed by the pressure plate 9, dust is generated. The vacuum cleaner 23 is driven so that the vacuum hose 22 can vacuum the dust generated inside the protective cover 7 and transport it to the collection box 24 through the conveying pipe.

[0026] refer to Figure 3 and Figure 4The cleaning mechanism includes two symmetrical fixed frames 13 installed at the top edges of the placement plate 5. A second sliding rod 14 is fixedly connected inside one fixed frame 13, and a lead screw 15 is rotatably installed inside the other fixed frame 13. Symmetrical second sliding blocks 16 are fitted onto the second sliding rod 14 and the lead screw 15. A cleaning brush 17 is connected between the second sliding blocks 16. One end of the lead screw 15 is also connected to a transmission assembly that drives the cleaning brush 17 to move back and forth for cleaning. The transmission assembly includes a second transmission wheel 18 installed at one end of the lead screw 15, which is fitted onto one end of a transmission belt 19. The other end of 19 is fitted with the first transmission wheel 20. The first transmission wheel 20 is fixedly installed on one end of the transmission shaft set at the output end of the servo motor 21. The servo motor 21 is fixedly installed on the top of the detection table 1 near the edge of the placement plate 5. More specifically, when cleaning the concrete residue on the placement plate 5, the servo motor 21 is driven to rotate the first transmission wheel 20. The first transmission wheel 20 drives the second transmission wheel 18 to rotate through the transmission belt 19, so that the lead screw 15 rotates and drives the cleaning brush 17 to move back and forth along the surface of the placement plate 5 to sweep the concrete residue to the opening and slide it into the collection box 24, thereby improving the cleaning effect.

[0027] The implementation principle of a concrete quality testing device based on building engineering in this application embodiment is as follows: During use, concrete is placed on the placement plate 5, and the electric telescopic rod 4 is driven to move the protective cover 7 connected to the bottom of the U-shaped connecting frame 6 downward. The first sliding block 10 set on the side walls at both ends of the protective cover 7 slides downward along the first sliding rod 11 and squeezes the buffer spring 12, so that the protective cover 7 avoids collision with the placement plate 5 during the downward movement. Then, the hydraulic cylinder 8 is driven to move the pressure plate 9 downward to perform a compression test on the concrete. When the concrete is crushed by the pressure plate 9, dust is generated. The vacuum cleaner 23 is driven so that the vacuum hose 22 can vacuum the dust generated inside the protective cover 7 and transport it to the collection box 24 through the conveying pipe. After the concrete is tested, the servo motor 21 is driven to rotate the first transmission wheel 20. The first transmission wheel 20 drives the second transmission wheel 18 to rotate through the transmission belt 19, so that the lead screw 15 rotates and drives the cleaning brush 17 to move back and forth along the surface of the placement plate 5 to sweep the concrete debris to the opening and let it slide into the collection box 24, thereby improving the cleaning effect.

[0028] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
