Description

Technical Field

[0001] The utility model relates to the field of cement setting detection, in particular to a device for detecting the setting speed of cement. Background Art

[0002] The physical and chemical properties of cement directly affect the strength and durability of buildings, which are related to life safety and national property safety. The setting time of cement is divided into initial setting and final setting. The time from adding water until the cement paste begins to lose plasticity and the fluidity decreases is called the initial setting time. The time from adding water until the cement paste completely loses plasticity and begins to have a certain structural strength is called the final setting time.

[0003] In order to measure the setting speed of cement, a detection device is usually required. In the existing detection device, the test method is to manually release the test needle at regular intervals, record the sinking depth each time, and finally obtain the initial setting and final setting times of cement. This process completely depends on the tester to continuously observe and time, which is time-consuming and laborious. Moreover, using the manual measurement method, there are many uncertain factors in the measurement process, which affect the objectivity of the measurement results. Summary of the Utility Model

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A device for detecting the setting speed of cement, including a detection frame, a lifting motor is fixedly connected to the top of the detection frame, a lifting groove is opened on the outer wall of the detection frame, the output end of the lifting motor is fixedly connected with a lifting screw rod, the bottom of the lifting screw rod is movably connected to the bottom inner wall of the lifting groove, a lifting block is threadedly connected to the outer wall of the lifting screw rod, a telescopic groove is opened at one end of the lifting block located inside the detection frame, a spring is fixedly connected to the inner wall of the telescopic groove, the other end of the spring is fixedly connected with a telescopic block, a sliding column is fixedly connected to the outer wall of the telescopic block, and the number of sliding columns is two. Sliding grooves are opened on the outer wall of the telescopic block, and the number of sliding grooves is two. Baffles are fixedly connected to the inner wall of the detection frame, and the number of baffles is two. Linkage grooves are opened inside both baffles. A sleeve is fixedly connected to the top inner wall of the detection frame, a detection rod is installed inside the sleeve, a limiting plate is fixedly connected to the outer wall of the detection rod, and a limiting groove is opened on the outer wall of the sleeve.

[0006] As a further description of the above technical solution:

[0007] The other end of the sliding column sequentially penetrates through the sliding groove and the linkage groove, and the limiting plate is located inside the limiting groove.

[0008] As a further description of the above technical solution:

[0009] A turntable groove is formed at the bottom of the inner wall of the detection frame. A turntable is installed inside the turntable groove. A gear groove is formed on the outer wall of the turntable, and a mounting groove is formed at the top of the turntable.

[0010] As a further description of the above technical solution:

[0011] A driving groove is formed on the inner wall of the turntable groove. A driving motor is fixedly connected to the bottom of the inner wall of the detection frame. The output end of the driving motor is fixedly connected to a driving gear. The driving gear is located inside the driving groove, and the driving gear meshes with the gear groove.

[0012] As a further description of the above technical solution:

[0013] A molding die is installed on the top of the turntable. The bottom of the molding die is fixedly connected to a mounting block.

[0014] As a further description of the above technical solution:

[0015] One end of the telescopic block away from the spring is beveled, and the mounting block is located inside the mounting groove.

[0016] The utility model has the following beneficial effects:

[0017] 1. By setting up a lifting motor, in the initial state, the top of the limit plate and the detection rod is located at the upper end inside the sleeve. However, there is still a certain distance between the limit plate and the top inner wall of the limit groove. At the same time, the height of the lifting block is lower than that of the limit plate, and the upper surface of the telescopic block is in contact with the bottom surface of the limit plate, so that the telescopic block supports the limit plate. The sliding column connected to the outer wall of the telescopic block is located at the leftmost side of the sliding groove, and at the same time, the sliding column is located in the upper part of the linkage groove. When conducting a detection, the lifting motor operates to drive the lifting lead screw to rotate, causing the lifting block to move upward by a certain distance first. When the lifting block moves upward, the sliding column moves along the inner wall of the linkage groove, and at the same time, the sliding column moves from the left side to the right side along the sliding groove. While the telescopic block moves upward, it retracts into the telescopic groove opened inside the lifting block, thereby separating the telescopic block from the limit plate and causing the detection rod to move downward into the cement to be detected. Subsequently, the lifting motor runs in the reverse direction, and the telescopic block and the lifting block move downward together. During this process, the spring rebounds and the telescopic block returns to its original position. When the telescopic block moves downward and contacts the limit plate, it will move into the telescopic groove due to the effect of the limit plate. After the telescopic block completely passes through the limit plate, the spring rebounds and the telescopic block returns to its original position to support the limit plate again. Subsequently, the motor runs in the reverse direction again, driving the lifting block and the telescopic block to move upward, so that the limit plate and the detection rod move upward to the initial position and then stop. Subsequently, after waiting for a period of time, the lifting motor repeats the process of the first detection again to detect the cement again. The whole process is convenient and fast, accurately controlling the detection interval time, avoiding the detection errors caused by various uncertain factors during the detection by the tester. In the existing device, the testing method is to manually release the test needle at regular intervals, record the sinking depth each time, and finally obtain the initial setting and final setting times of the cement. This process completely relies on the tester to continuously observe and time, which is time-consuming and laborious. Moreover, using the manual measurement method, there are many uncertain factors during the measurement process, affecting the objectivity of the measurement results. This device avoids the detection errors caused by various uncertain factors during the detection by the tester. The process is simple, convenient and fast.

[0018] 2. By setting up a driving motor, when the driving motor operates, it drives the driving gear to rotate, and the turntable rotates with the rotation of the driving gear, enabling the forming mold to rotate intermittently in cooperation with the lifting motor after the detection rod enters and exits the inside of the forming mold, avoiding the errors caused by the detection rod detecting at the same position of the cement multiple times.

[0028] Refer to Figure 1-7 As shown in the figure, a cement setting speed detection device provided by the present utility model includes a detection frame 1. A lifting motor 2 is fixedly connected to the top of the detection frame 1. A lifting groove 3 is opened on the outer wall of the detection frame 1. The output end of the lifting motor 2 is fixedly connected to a lifting screw rod 4. The bottom of the lifting screw rod 4 is movably connected to the inner bottom of the lifting groove 3. A lifting block 5 is threadedly connected to the outer wall of the lifting screw rod 4. One end of the lifting block 5 located inside the detection frame 1 is provided with a telescopic groove 6. A spring 7 is fixedly connected to the inner wall of the telescopic groove 6. The other end of the spring 7 is fixedly connected to a telescopic block 8. The outer wall of the telescopic block 8 is fixedly connected to a slide column 9, and the number of slide columns 9 is two. Slide grooves 10 are opened on the outer wall of the telescopic block 8, and the number of slide grooves 10 is two. Baffles 11 are fixedly connected to the inner wall of the detection frame 1, and the number of baffles 11 is two. Linkage grooves 12 are opened inside both baffles 11. A sleeve 13 is fixedly connected to the inner top of the detection frame 1. A detection rod 14 is installed inside the sleeve 13. A limiting plate 15 is fixedly connected to the outer wall of the detection rod 14. A limiting groove 16 is opened on the outer wall of the sleeve 13.

[0029] In the initial state, the top of the limit plate 15 and the detection rod 14 is located at the upper end inside the sleeve 13. However, there is still a certain distance between the limit plate 15 and the top of the inner wall of the limit groove 16. At the same time, the height of the lifting block 5 is lower than that of the limit plate 15, and the upper surface of the telescopic block 8 is in contact with the bottom surface of the limit plate 15, so that the telescopic block 8 supports the limit plate 15. The sliding column 9 connected to the outer wall of the telescopic block 8 is located at the leftmost side of the sliding groove 10. At the same time, the sliding column 9 is located at the upper end inside the linkage groove 12. When performing detection, the lifting motor 2 operates, driving the lifting screw rod 4 to rotate, so that the lifting block 5 first moves upward by a certain distance. When the lifting block 5 moves upward, the sliding column 9 moves along the inner wall of the linkage groove 12. At the same time, the sliding column 9 moves from the left side to the right side along the sliding groove 10. While the telescopic block 8 moves upward, it retracts into the telescopic groove 6 opened inside the lifting block 5. Thus, the telescopic block 8 is separated from the limit plate 15, and the detection rod 14 descends into the cement to be detected. Subsequently, the lifting motor 2 runs in the reverse direction, and the telescopic block 8 and the lifting block 5 move downward together. During this process, the spring 7 rebounds, and the telescopic block 8 returns to its original position. When the telescopic block 8 moves downward and contacts the limit plate 15, due to the action of the limit plate 15, it moves into the telescopic groove 6. After the telescopic block 8 completely passes through the limit plate 5, the spring 7 rebounds, and the telescopic block 8 returns to its original position and supports the limit plate 15 again. Subsequently, the lifting motor 2 runs in the reverse direction again, driving the lifting block 5 and the telescopic block 8 to move upward. Thus, the limit plate 15 and the detection rod 14 move upward to the initial position and then stop. Subsequently, after waiting for a period of time, the lifting motor 2 repeats the process of the first detection again and detects the cement again. The whole process is convenient and fast, accurately controlling the detection interval time, and avoiding detection errors caused by various uncertain factors during the detection by the tester.

[0030] The other end of the sliding column 9 sequentially penetrates through the sliding groove 10 and the linkage groove 12, and the limit plate 15 is located inside the limit groove 16.

[0031] A turntable groove 17 is opened at the bottom of the inner wall of the detection frame 1. A turntable 18 is installed inside the turntable groove 17. A gear groove 19 is opened on the outer wall of the turntable 18. An installation groove 20 is opened at the top of the turntable 18. A driving groove 21 is opened on the inner wall of the turntable groove 17. A driving motor 22 is fixedly connected to the bottom of the inner wall of the detection frame 1. The output end of the driving motor 22 is fixedly connected to a driving gear 23. The driving gear 23 is located inside the driving groove 21. The driving gear 23 meshes with the gear groove 19. A forming die 24 is installed on the top of the turntable 18. A mounting block 25 is fixedly connected to the bottom of the forming die 24. One end of the telescopic block 8 away from the spring 7 is beveled, and the mounting block 25 is located inside the installation groove 20.

[0032] Install the mounting block 25 at the bottom of the forming die 24 into the mounting groove 20 at the top of the turntable 18. The driving motor 22 operates in conjunction with the lifting motor 2. When the driving motor 22 operates, it drives the driving gear 23 to rotate, and the turntable 18 rotates with the rotation of the driving gear 23, enabling the forming die 24 to cause the turntable 18 to rotate intermittently after the detection rod 14 enters and exits the inside of the forming die 24, avoiding errors caused by the detection rod 14 detecting at the same position of the cement multiple times.

[0033] Working principle: Through an external programming program, the running times of the lifting motor 2 and the driving motor 22 are set in advance. Install the mounting block 25 at the bottom of the forming die 24 into the mounting groove 20 at the top of the turntable 18 to ensure that the forming die 24 can rotate together with the turntable 18. In the initial state, the top of the limit plate 15 and the detection rod 14 is located at the upper end inside the sleeve 13, but there is still a certain distance between the limit plate 15 and the top inner wall of the limit groove 16. At the same time, the height of the lifting block 5 is lower than the height of the limit plate 15, and the upper surface of the telescopic block 8 is in contact with the bottom surface of the limit plate 15, enabling the telescopic block 8 to support the limit plate 15. The sliding column 9 connected to the outer wall of the telescopic block 8 is located at the leftmost side of the sliding groove 10, and at the same time, the sliding column 9 is located at the position in the attached drawing of the specification Figure 7 During detection, the lifting motor 2 operates, driving the lifting screw rod 4 to rotate, causing the lifting block 5 to move upward a certain distance first. When the lifting block 5 moves upward, the sliding column 9 moves along the inner wall of the linkage groove 12, and at the same time, the sliding column 9 moves from the left side to the right side along the sliding groove 10. While the telescopic block 8 moves upward, it retracts into the telescopic groove 6 opened inside the lifting block 5, thereby separating the telescopic block 8 from the limit plate 15 and causing the detection rod 14 to move downward into the cement to be detected. Subsequently, the lifting motor 2 runs in the reverse direction, and the telescopic block 8 and the lifting block 5 move downward together. During this process, the spring 7 rebounds, and the telescopic block 8 returns to its original position. When the telescopic block 8 moves downward and contacts the limit plate 15, it will move into the telescopic groove 6 due to the action of the limit plate 15. After the telescopic block 8 completely passes through the limit plate 5, the spring 7 rebounds, and the telescopic block 8 returns to its original position, supporting the limit plate 15 again. Subsequently, the lifting motor 2 runs in the reverse direction again, driving the lifting block 5 and the telescopic block 8 to move upward, thereby causing the limit plate 15 and the detection rod 14 to move upward to the initial position and stop, enabling the forming die 24 to cause the turntable 18 to rotate intermittently after the detection rod 14 enters and exits the inside of the forming die 24, avoiding errors caused by the detection rod 14 detecting at the same position of the cement multiple times.
