Description

Technical Field

[0001] This utility model relates to the field of building material testing technology, specifically a building material hardness testing device. Background Technology

[0002] Building materials refer to all materials and their products used in construction projects, forming the material basis of these projects. Their performance directly affects the safety, durability, functionality, and economy of buildings. Hardness testing of building materials is an important means of evaluating their mechanical properties, directly related to their durability, wear resistance, load-bearing capacity, and engineering safety. Different building materials exhibit significant differences in physical properties; therefore, hardness testing methods, instruments, and standards each have their own emphasis.

[0003] Hardness testing devices are needed in the production of building materials. Chinese utility model patent CN221377542U discloses a hardness testing device for building materials, relating to the field of building material testing technology. This utility model includes a main structure, comprising a worktable and a mounting frame mounted on the upper wall of the worktable, with a connecting block fixedly connected to one side wall of the mounting frame; and a pushing mechanism, including a mounting assembly located on one side of the testing area, comprising a groove plate, a fixed shaft, and a conveying roller. After testing, the operator drives an electric push rod, which, through the action of the push plate, facilitates the pushing of the building material block into the mounting assembly. Utilizing the characteristic of the conveying roller rotating and mounted on the outer wall of the fixed shaft, the building material is easily slid out, avoiding the safety hazard of personnel directly taking the material block from below the detector.

[0004] However, this utility model can only test one type of building material during use. When multiple building materials need to be tested, the previous one must be removed and then the new building material must be placed on top, which greatly reduces the testing efficiency and cannot meet production needs. Therefore, a building material hardness testing device is proposed to solve the problems mentioned above. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a building material hardness testing device, which has the advantage of conveniently testing multiple materials sequentially. It solves the problem that existing testing devices can only test one type of building material, and when multiple building materials need to be tested, the previous one must be removed and then the new building material is placed, which greatly reduces the testing efficiency and cannot meet production needs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a building material hardness testing device, comprising a workbench and a testing device body disposed on the top of the workbench, wherein the top of the workbench is provided with a grooved wheel mechanism capable of storing multiple building materials;

[0007] The grooved wheel mechanism includes a placement plate rotatably connected to the top of the workbench, a placement groove being formed on the upper surface of the placement plate, a fixed plate being fixedly connected inside the workbench, a rotating plate being rotatably connected to the top of the fixed plate, a drive motor capable of driving the rotating plate being fixedly connected inside the workbench, a grooved wheel being rotatably connected to the upper surface of the fixed plate, and a connecting shaft being fixedly connected between the placement plate and the grooved wheel.

[0008] Furthermore, the number of placement slots is four, and the four placement slots are evenly distributed on the top of the placement plate.

[0009] Furthermore, a protrusion is fixedly connected to the upper surface of the rotating plate, and an movable groove adapted to the protrusion is opened inside the grooved wheel. A limiting block capable of limiting the grooved wheel is fixedly connected to the top of the rotating plate.

[0010] Furthermore, a support box is fixedly connected to the back of the top of the workbench, and an electric push rod extending to the bottom of the support box is fixedly connected to the top of the support box. A moving block is fixedly connected to the output end of the electric push rod.

[0011] Furthermore, a connecting rod is fixedly connected between the moving block and the detection device body, and a sliding groove adapted to the connecting rod is provided on the front of the support box.

[0012] The moving block is fixedly connected to positioning blocks extending into the support box on both its left and right sides, and the support box has positioning grooves on its inner wall that are adapted to the positioning blocks.

[0013] Furthermore, the bottom of the workbench is rotatably connected to four casters, which are evenly distributed on the bottom of the workbench.

[0014] Compared with the prior art, this utility model provides a device for testing the hardness of building materials, which has the following beneficial effects:

[0015] 1. This building material hardness testing device uses a drive motor to rotate a rotating plate. A grooved wheel is installed so that the protrusions on the rotating plate cause the grooved wheel to rotate intermittently, thus intermittently rotating the placement plate. Four placement slots allow for the simultaneous placement of four building materials, facilitating sequential hardness testing and improving testing efficiency.

[0016] 2. This building material hardness testing device uses an electric push rod to move a moving block downwards, which in turn moves the testing device body downwards, enabling hardness testing of building materials placed on the plate. This solves the problem that existing testing devices can only test one type of building material, and when multiple building materials need to be tested, the previous one must be removed and a new one placed on top, which greatly reduces testing efficiency and cannot meet production needs.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 and Figure 2 This embodiment of a building material hardness testing device includes a workbench 1 and a testing device body 2 disposed on the top of the workbench 1. The top of the workbench 1 is provided with a grooved wheel mechanism capable of storing multiple building materials. The grooved wheel mechanism includes a placement plate 3 rotatably connected to the top of the workbench 1. A placement groove 4 is formed on the upper surface of the placement plate 3. A fixing plate 6 is fixedly connected inside the workbench 1. A rotating plate 8 is rotatably connected to the top of the fixing plate 6. A drive motor 5 capable of driving the rotating plate 8 is fixedly connected inside the workbench 1. A grooved wheel 7 is rotatably connected to the upper surface of the fixing plate 6. A connecting shaft is fixedly connected between the placement plate 3 and the grooved wheel 7.

[0023] Specifically, there are four placement slots 4, which are evenly distributed on the top of the placement plate 3. A protrusion 10 is fixedly connected to the upper surface of the rotating plate 8. The groove wheel 7 has an movable groove that matches the protrusion 10. A limiting block 9 that can limit the groove wheel 7 is fixedly connected to the top of the rotating plate 8.

[0024] It should be noted that by setting the drive motor 5 to drive the rotating plate 8 to rotate, and by setting the grooved wheel 7, the protrusion 10 on the rotating plate 8 can drive the grooved wheel 7 to rotate intermittently during the rotation, thereby enabling the placement plate 3 to rotate intermittently. Furthermore, by setting four placement slots 4, four building materials can be placed simultaneously, which facilitates the sequential hardness testing of the four building materials and improves the testing efficiency.

[0025] Please see Figure 1 and Figure 3 In this embodiment, a support box 11 is fixedly connected to the back of the top of the workbench 1. An electric push rod 12 extending to the bottom of the support box 11 is fixedly connected to the top of the support box 11. A moving block 13 is fixedly connected to the output end of the electric push rod 12. A connecting rod 14 is fixedly connected between the moving block 13 and the detection device body 2. A sliding groove adapted to the connecting rod 14 is opened on the front of the support box 11.

[0026] Specifically, positioning blocks extending into the support box 11 are fixedly connected to both the left and right sides of the movable block 13, and positioning grooves that are adapted to the positioning blocks are provided on the inner wall of the support box 11.

[0027] It should be noted that the main body 2 of the testing device is a Brinell hardness tester. For medium and low hardness building materials such as steel, aluminum alloy, copper alloy, concrete, and stone, a cemented carbide ball or steel ball of a certain diameter is pressed into the surface of the material with a specified test force. After holding for a certain period of time, the test force is removed, the diameter of the indentation is measured, and the Brinell hardness value is calculated by formula. The indentation area is relatively large, which can reflect the overall average hardness of the material. It is suitable for testing non-uniform materials, especially building materials with low hardness but possible minor surface defects.

[0028] Please see Figure 1 In this embodiment, four movable wheels 15 are rotatably connected to the bottom of the workbench 1. The four movable wheels 15 are evenly distributed on the bottom of the workbench 1, and a brake pad is hinged to one side of each movable wheel 15.

[0029] The working principle of the above embodiments is as follows:

[0030] First, the staff places the four building materials on the four placement slots 4 respectively. Then, the electric push rod 12 is started to move the testing device body 2 downward. At this time, the testing device body 2 performs hardness testing on one of the building materials. After the test is completed, the drive motor 5 is started to drive the groove wheel 7 to rotate, thereby driving the placement plate 3 to rotate and test the other building material. In this way, the four building materials are tested in sequence.

[0031] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
