Description

Technical Field

[0001] This utility model belongs to the field of concrete testing technology, and in particular relates to a device for testing the particle uniformity of EPS lightweight thermal insulation concrete. Background Technology

[0002] In the construction industry, EPS (polystyrene foam) lightweight insulating concrete, as a new type of building material, is widely used in the insulation construction of building structures such as walls and roofs due to its advantages such as good thermal insulation performance, light weight and relatively low cost. The performance and quality of EPS lightweight insulating concrete directly affect the insulation effect, structural safety and durability of buildings, and the uniform distribution of EPS particles in concrete is one of the key factors affecting its performance.

[0003] Currently, traditional methods for detecting the uniformity of EPS lightweight thermal insulation concrete particles largely rely on manual sampling and simple visual inspection. In practice, construction workers typically randomly select a certain amount of sample from the mixed concrete and then visually observe the distribution of EPS particles. However, manual visual inspection is easily influenced by personal experience and subjective factors, and different inspectors may obtain different results, making it difficult to guarantee the accuracy and reliability of the test results. Furthermore, random sampling may not fully reflect the uniform distribution of EPS particles throughout the entire concrete batch, easily leading to local sampling biases and affecting the overall quality assessment of the concrete. In addition, during the testing process, it is necessary to compare and analyze concrete from different locations to determine the degree of particle distribution uniformity. However, existing testing methods lack effective equipment to assist in the accurate acquisition and comparative observation of samples from different locations, further limiting the accurate detection of EPS lightweight thermal insulation concrete particle uniformity. Summary of the Invention

The rotating seat is sleeved on the upper end of the rack and connected to the mounting frame, thereby driving the mounting frame to lift and rotate. This facilitates the adjustment of the position of the concrete vibrator and camera on the mounting frame to adapt to the needs of different experimental steps and improve the flexibility and comprehensiveness of the detection.

[0011] Optionally, the surface of the mounting box is provided with a control panel, and the mounting box contains a controller electrically connected to the control panel, and the drive motor is electrically connected to the controller.

[0012] By adopting the above technical solution, a control panel is set on the surface of the mounting box. The internal controller is electrically connected to the control panel and the drive motor. Operators can conveniently control the operation of the drive motor and electrical components on the mounting frame through the control panel, thereby controlling the lifting and rotation of the mounting frame, realizing the automated operation of the device, improving detection efficiency and ease of operation.

[0013] Optionally, the mounting frame is L-shaped, with a movable rod on the mounting frame and a fixed seat at the other end of the movable rod. The camera is mounted on the fixed seat, and the concrete vibrator is mounted on the other end of the mounting frame. The mounting frame has through holes for mounting the concrete vibrator.

[0014] By adopting the above technical solution, the mounting frame is L-shaped and equipped with movable rods and fixed seats, which facilitates flexible adjustment of the camera's shooting position and angle to obtain clearer and more comprehensive images of EPS particle distribution in concrete; the concrete vibrator is installed at the other end of the mounting frame through perforation, which is a reasonable structure that facilitates the vibration operation of concrete and promotes uniform particle distribution.

[0015] Optionally, each of the experimental boxes is provided with a bearing seat, and a rotating shaft is installed between adjacent bearing seats; each of the experimental boxes is provided with a handle.

[0032] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] In the description of this utility model, it should be noted that the terms "middle", "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0034] like Figure 1 As shown in Figure 6, the specific scheme of the embodiment is as follows: An EPS lightweight thermal insulation concrete particle uniformity testing device includes a vibration table 1. The vibration table 1 provides a vibration environment for testing, simulates the vibration situation in the actual concrete construction process, and causes the concrete particles to redistribute under the action of vibration so as to observe their uniformity. The vibration table 1 is a known technology, so the specific structure of the vibration table 1 is not described in detail here.

[0035] The vibration table 1 is equipped with a hollow column 2. The column 2 serves as a supporting structure for the device, connecting and fixing other components, while providing space for the installation and movement of the internal gear 45. The hollow design reduces its weight and ensures unimpeded installation and movement of the internal gear 45, guaranteeing the normal operation of the lifting and rotating assembly 4. The side wall of the column 2 has mounting holes, providing a stable mounting position for the driven gear 44, ensuring the accuracy and reliability of gear transmission. The upper surface of the vibration table 1 has a through hole 101 for the column 2 to pass through, connecting the column 2 to the base plate of the vibration table 1. The through hole 101 ensures the connection between the column 2 and the base plate of the vibration table 1, making the entire column 2 structure more stable and ensuring that the normal operation of the components on the column 2 is not affected during vibration.

[0036] The upper end of the column 2 is provided with a mounting frame 3, which is L-shaped. The mounting frame 3 is used to install the concrete vibrator 5 and the camera 6. It is a support platform for these two components and is connected to the lifting and rotating assembly 4 to realize lifting and rotating movements. The L-shaped design reasonably allocates the installation space, so that the concrete vibrator 5 and the camera 6 can be easily switched to meet the testing requirements.

[0037] A lifting and rotating assembly 4 is provided between the mounting frame 3 and the column 2. The lifting and rotating assembly includes a mounting box 41 mounted on the column 2. A control panel 411 is provided on the surface of the mounting box 41. A controller 412 electrically connected to the control panel 411 is provided inside the mounting box 41. The drive motor 42 is electrically connected to the controller 412. The drive motor 42 is provided inside the mounting box 41. A drive gear 43 is installed at the output end of the drive motor 42. A driven gear 44 meshing with the drive gear 43 is provided on the column 2. The driven gear 44 is installed in the mounting hole through a connecting shaft. A rack 45 meshing with the driven gear 44 is installed inside the column 2. A rotating seat 46 connected to the mounting frame 3 is sleeved on the upper end of the rack 45.

[0038] The drive motor 42 drives the active gear 43 to rotate, and the active gear 43 meshes with the driven gear 44, which in turn causes the driven gear 44 to drive the rack 45 to move up and down. The rotating seat 46 at the upper end of the rack 45 is connected to the mounting frame 3, so the mounting frame 3 can move up and down with the rack 45. During the test, the vertical position of the concrete vibrator 5 and the camera 6 can be adjusted according to the height and distribution of the concrete in the test box 8 to ensure that the vibrator can effectively act on the concrete and the camera 6 can clearly capture the distribution of concrete particles. The rotation function allows for easy switching between the concrete vibrator 5 and the camera 6. After the concrete vibrator 5 is used up, the camera 6 can be quickly switched by rotating the rotating seat 46, avoiding the trouble of frequently moving the entire device or test box 8 and adding a camera 6 mounting frame 3.

[0039] The mounting frame 3 is equipped with a concrete vibrator 5 and a camera 6. The concrete vibrator 5 can vibrate the concrete in the experimental box 8. By designing the concrete vibrator 5, the vibration mode of the concrete can be switched. By implementing different vibration conditions, the actual construction vibration environment can be simulated, and the true distribution state of EPS particles in the concrete during the construction pouring and vibration process can be simulated.

[0040] Camera 6 can acquire images of the distribution of concrete particles in the experimental box 8. Through image data analysis and pattern recognition, it can detect minute changes and defects on the surface of the object and determine the uniformity of the concrete particles. The camera is an AI smart camera, which is an intelligent device that integrates image acquisition, processing, transmission and control functions. It can detect minute changes and defects on the surface of the object through image data analysis and pattern recognition. It can adapt to various environments and effectively complete the product inspection task in complex industrial production environments.

[0041] The mounting frame 3 is provided with a movable rod 301, and the other end of the movable rod 301 is provided with a fixed seat 302. The camera 6 is mounted on the fixed seat 302. The design of the movable rod 301 allows the position of the camera 6 to be adjusted to obtain a better shooting position, which enhances the flexibility of the device. The concrete vibrator 5 is mounted on the other end of the mounting frame 3, and the mounting frame 3 is provided with a through hole 303 for mounting the concrete vibrator 5.

[0042] The surface of the vibration table 1 is provided with a mounting groove 7, which is used to install the test box 8, providing a stable placement position for the test box 8, ensuring the stability of the test box 8 on the vibration table 1, and enabling the test box 8 to vibrate together with the vibration table 1. At the same time, it facilitates the installation and disassembly of the test box 8. The mounting groove 7 is provided with several vertically installed test boxes 8, which are used to hold the EPS lightweight thermal insulation concrete to be tested. They are the carriers for testing the uniformity of concrete particles, providing a standard testing space, so that the concrete can be tested in the same environment, ensuring the accuracy of the test results.

[0043] Each of the aforementioned experimental boxes 8 is provided with a bearing seat 801, and a rotating shaft 802 is installed between adjacent bearing seats 801. The design of the bearing seat 801 and the bearing allows the adjacent experimental boxes 8 to rotate relative to each other, realizing a flexible connection between the experimental boxes 8, facilitating the opening and closing of the experimental boxes 8, and providing convenience for subsequent concrete testing. Each of the aforementioned experimental boxes 8 is provided with a handle 803, which allows the operator to hold the experimental box 8 and perform operations such as opening, closing and moving the experimental box 8.

[0044] A groove 804 is provided between adjacent experimental boxes 8, providing space for the installation of the partition plate 9. The groove 804 is located on the upper experimental box 8. A partition plate 9 is provided between several experimental boxes 8, located inside the groove 804. The partition plate 9 is L-shaped, and a handle 901 is installed on the surface of the partition plate 9. The partition plate 9 is used to separate adjacent experimental boxes 8, preventing concrete from falling out of the experimental boxes 8 when taking pictures. The side wall of the groove is provided with an insertion slot, and the partition plate is provided with an insertion strip that matches the insertion slot.

[0045] The experimental steps of the above embodiments are as follows:

[0046] The experimental box 8 is vertically installed in the mounting groove 7 on the surface of the vibration table 1, so that multiple experimental boxes 8 are arranged into a long strip-shaped experimental box 8. The prepared EPS lightweight thermal insulation concrete sample is poured into the experimental box 8 through the opening on the top of the experimental box 8.

[0047] According to the experimental requirements, the vibration parameters of the vibration table 1, such as vibration frequency and vibration time, are set. The vibration table 1 is then started to vibrate according to the set parameters to simulate the vibration situation in the actual concrete construction process, so that the concrete particles are redistributed under the action of vibration.

[0048] Meanwhile, another vibration condition can be provided by using a concrete vibrator 5. By operating the lifting and rotating component 4 through the control panel 411, the mounting frame 3 is lowered to a suitable height so that the concrete vibrator 5 can be inserted into the concrete in the test box 8. During the descent, pay attention to the positional relationship between the vibrator and the test box 8 to avoid collision between the vibrator and the wall of the test box 8.

[0049] Start the concrete vibrator 5 to vibrate the concrete in the test box 8. During the vibration process, control the vibration time and vibration force according to the characteristics of the concrete and the experimental requirements to make the concrete more compact and further promote the uniform distribution of concrete particles.

[0050] After vibration is completed, the mounting frame 3 is raised by the lifting and rotating component 4, so that the concrete vibrator 5 leaves the test box 8.

[0051] One of the two vibration conditions in the above steps can be selected after the vibration is completed;

[0052] By rotating the rotating base 46, the camera 6 is quickly switched to the working position. The position of the camera 6 is adjusted using the movable rod 301 so that its lens is directly facing the concrete surface inside the experimental chamber 8, allowing for a clear image of the distribution of concrete particles. During the adjustment process, the shooting effect can be observed in real time through the preview function of the camera 6 to ensure that the shooting position and angle are appropriate.

[0053] Turn on camera 6 and first capture an image of the topmost experimental box 8. After the image is captured, insert the spacer 9 and rotate the next experimental box 8 using the pivot 801 and the rotating shaft 802. After rotating to an uncovered position, capture an image of the next experimental box 8. Use the same steps to capture images of the remaining experimental boxes 8 in sequence.

[0054] The image data captured by camera 6 is transmitted to the computer and categorized for storage, so that it can be analyzed and processed later.

[0055] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
