Description

Technical Field

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

[0002] Cement strength testing is an important indicator for evaluating cement quality and a basis for classifying cement strength grades. Cement strength refers to the ability of a hardened cement mortar specimen to withstand external force damage, expressed in MPa (megapascals). It is one of the important physical and mechanical properties of cement.

[0003] Existing cement testing devices generate fragments during the testing process, which need to be cleaned up before subsequent cement testing can proceed. However, the cleaning process is mostly done manually, which not only increases the workload of workers but also has low efficiency, preventing the device from continuously and efficiently testing cement and thus reducing its performance. Therefore, there is an urgent need for a cement testing device to solve the above problems. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] The technical problem to be solved by this utility model is to provide a cement testing device that can automatically clean up cement fragments, automatically feed cement, has high testing efficiency, and good performance, in light of the current state of the technology.

[0006] (II) Technical Solution

[0007] This utility model is achieved through the following technical solution: This utility model proposes a cement testing device, including a testing platform, a bearing plate fixed in the middle of the testing platform, a conveyor belt installed on the outer side of the bearing plate, a drive motor connected to one side of the conveyor belt, multiple sets of partition plates fixed in an array on the conveyor belt, a collection box fixed on the back wall of the testing platform, a bracket fixed at the upper end of the testing platform, and a hydraulic rod provided on the bracket.

[0008] Furthermore, the conveyor belt is rotatably mounted on the testing platform, and the output shaft of the drive motor is fixedly connected to the rotating shaft inside the conveyor belt.

[0009] By adopting the above technical solution, the drive motor can drive the conveyor belt to rotate, which can automatically transport cement to the detection position.

[0010] Furthermore, the separator plate is screwed onto the conveyor belt, and the bearing plate is welded inside the testing station.

[0011] By adopting the above technical solution, the separator plate can divide the conveyor belt into different placement spaces, and the bearing plate can provide auxiliary support for the cement during the testing process.

[0012] Furthermore, the collection box is movably placed below one end of the conveyor belt, and the bracket is welded to the detection table.

[0013] By adopting the above technical solution, after a set of cement tests is completed, the conveyor belt operates, on the one hand transporting the next set of cement to the testing position, and on the other hand transporting the cement fragments generated by the previous set, so that they automatically fall into the collection box for collection. This realizes automatic cleaning of cement fragments while feeding materials, enabling the device to continuously and efficiently test cement, and the effect of use is good.

[0014] Furthermore, the hydraulic rod is fixed to the bracket by bolts, and a telescopic protective cover is fixed to the output end of the hydraulic rod.

[0015] By adopting the above technical solution, the hydraulic rod drives the telescopic protective cover to move down, so that the top pin applies pressure to the cement, thereby testing the cement. The telescopic protective cover can seal the testing environment, thereby preventing cement fragments from splashing.

[0016] Furthermore, a spring is provided between the fixed part and the movable part of the telescopic protective cover, and there are four sets of springs distributed at the four corners of the telescopic protective cover.

[0017] By adopting the above technical solution, during the operation of the hydraulic rod, the movable part of the telescopic protective cover is in advance in contact with the surface of the conveyor belt, and at the same time, the telescopic protective cover can be continuously moved downward under the action of the spring, so that the ejector pin is in contact with the cement.

[0018] Furthermore, a T-shaped connecting frame is fixed inside the telescopic protective cover, and four sets of pressure sensors are fixed inside one end of the connecting frame.

[0019] By adopting the above technical solution, the pressure sensor can detect the compressive strength of cement.

[0020] Furthermore, a detection plate is fixed on the detection end face of the pressure sensor, and multiple sets of pins are arrayed and fixed on one side wall of the detection plate.

[0021] By adopting the above technical solution, the ejector pin continuously applies pressure to the cement from the left and right sides of the hydraulic rod, thereby detecting the cement.

[0022] (III) Beneficial Effects

[0023] Compared with the prior art, this utility model has the following advantages:

[0024] To address the problem that existing cement testing devices generate cement fragments during testing, requiring cleaning before subsequent cement tests can proceed, and that this cleaning process is largely manual, increasing worker workload and reducing efficiency, this invention addresses the issue by incorporating a drive motor, conveyor belt, and partition plates. During testing, the partition plates divide the conveyor belt into multiple storage spaces. Once a group of cement is tested, the drive motor activates the conveyor belt, simultaneously transporting the next group of cement to the testing position and collecting the cement fragments generated by the previous group. This automatic cleaning of cement fragments during feeding ensures continuous and efficient cement testing with excellent performance. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] like Figures 1-3As shown, a cement testing device in this embodiment includes a testing platform 1. A support plate 14 is fixed in the middle of the testing platform 1. The support plate 14 can provide auxiliary support for the cement during the testing process. A conveyor belt 2 is installed on the outer side of the support plate 14 of the testing platform 1. A drive motor 4 is connected to one side of the conveyor belt 2. The drive motor 4 drives the conveyor belt 2 to rotate, which can automatically transport the cement to the testing position. Multiple sets of partition plates 3 are fixed in an array on the conveyor belt 2. A collection box 5 is fixed on the back wall of the testing platform 1. The partition plates 3 divide the conveyor belt 2 into multiple placement spaces. After a set of cement is tested, the drive motor 4 drives the conveyor belt 2 to work. On the one hand, it transports the next set of cement to the testing position. On the other hand, it transports the cement fragments generated by the previous set and makes them fall into the collection box 5 for collection. It realizes automatic cleaning of cement fragments while feeding, which can enable the device to continuously and efficiently test cement. A bracket 6 is fixed at the upper end of the testing platform 1. A hydraulic rod 7 is set on the bracket 6. The hydraulic rod 7 drives the telescopic protective cover 8 to move down, so that the ejector pin 12 applies pressure to the cement, thereby testing the cement.

[0032] like Figures 1-3 As shown, in this embodiment, the conveyor belt 2 is rotatably mounted on the testing platform 1, the output shaft of the drive motor 4 is fixedly connected to the rotating shaft inside the conveyor belt 2, the separator plate 3 is screwed onto the conveyor belt 2, the bearing plate 14 is welded into the testing platform 1, the collection box 5 is movably placed below one end of the conveyor belt 2, the bracket 6 is welded onto the testing platform 1, the hydraulic rod 7 is fixed onto the bracket 6 with bolts, and a telescopic protective cover 8 is fixed to the output end of the hydraulic rod 7.

[0033] like Figures 1-3 As shown, in this embodiment, a spring 13 is provided between the fixed part and the movable part of the telescopic protective cover 8. There are four sets of springs 13 distributed at the four corners of the telescopic protective cover 8. During the operation of the hydraulic rod 7, the movable part of the telescopic protective cover 8 is in pre-contact with the surface of the conveyor belt 2. At the same time, under the action of the spring 13, the telescopic protective cover 8 can continuously move downward, eventually causing the ejector pin 12 to contact the cement. A T-shaped connecting frame 9 is fixed inside the telescopic protective cover 8. Four sets of pressure sensors 10 are fixed inside one end of the connecting frame 9. The pressure sensors 10 can detect the compressive strength of the cement. A detection plate 11 is fixed on the detection end face of the pressure sensor 10. Multiple sets of ejector pins 12 are arrayed and fixed on one side wall of the detection plate 11. The ejector pins 12 continuously apply pressure to the cement from the left and right sides of the hydraulic rod 7, thereby detecting it.

[0034] The specific implementation process of this embodiment is as follows: During use, an external power source is connected, cement is placed on the conveyor belt 2 and positioned between adjacent partition plates 3. The drive motor 4 drives the conveyor belt 2 to transport the cement to the detection position. Then, the hydraulic rod 7 drives the ejector pin 12 downwards. During this downward movement, the movable part of the telescopic protective cover 8 is in pre-contact with the surface of the conveyor belt 2. Simultaneously, the spring 13 allows the telescopic protective cover 8 to continuously move downwards, ultimately bringing the ejector pin 12 into contact with the cement. The hydraulic rod 7 continuously applies pressure to the cement through the ejector pin 12, and, in conjunction with the pressure sensor 10, detects the compressive strength of the cement. During the detection process, when the cement is under pressure... When excessive force causes splashing, the telescopic protective cover 8 can block it, thus protecting the staff. After a set of cement is tested, the drive motor 4 drives the conveyor belt 2 to work, on the one hand, to transport the next set of cement to the testing position, and on the other hand, to transport the cement fragments generated by the previous set, and let them fall into the collection box 5 for collection. This realizes automatic cleaning of cement fragments while feeding, which enables the device to continuously and efficiently test cement. The upper end of the testing table 1 is fixed with a bracket 6, and a hydraulic rod 7 is set on the bracket 6. The hydraulic rod 7 drives the telescopic protective cover 8 to move down, so that the ejector pin 12 applies pressure to the cement, thereby testing the cement.
