Description

Technical Field

[0001] The utility model relates to the technical field of testing, in particular to a cement detection device. Background Technique

[0002] During the use of cement, the water content is one of the important parameters affecting the quality of cement; when the water content in the cement is too much, the adhesion of the cement is insufficient and it cannot dry into blocks. If the water content in the cement is too little, the hardness of the cement is too high, and it is easy to break after drying into blocks, and the provided load is insufficient. Therefore, before the cement leaves the factory, the water consumption of the standard consistency in the cement must be detected many times, and only when it meets certain standards can it be sold to customers to prevent engineering accidents caused by cement quality problems and avoid losses of manpower and material resources. It is necessary to detect the cement.

[0003] The current cement detection device, as described in the patent with the publication number CN206906186U, includes a frame, an experimental cup is arranged on the frame, and a detection device is located above the experimental cup; the detection device includes a detection seat fixed on the frame and no less than 3 detection frames vertically arranged downward on the detection seat, and uniformly sized detection probes are slidably connected to the detection frames, and the detection probes on different detection frames have different weights.

Detailed Embodiments

[0021] The following further describes the technical solutions of this patent in detail with reference to the specific embodiments.

[0022] Please refer to Figures 1-3, a cement detection device, comprising a base 1. The top of the base 1 is rotatably connected with a rotating plate 2 through a rotating shaft. Both sides of the rotating plate 2 are fixedly connected with limiting blocks 3. The top of the limiting block 3 is provided with a limiting slot 4 in the vertical direction. The top of the rotating plate 2 is fixedly connected with two fixed rings 5 arranged at intervals left and right. Inside both of the two fixed rings 5, a test cup 6 is movably arranged. Inside the left test cup 6, a cleaning assembly 7 is arranged for cleaning the detection head 17. Inside the right test cup 6, a stirring assembly 8 is arranged for mixing and stirring water and cement. The top of the base 1 is provided with a locking assembly 9 corresponding to the limiting block 3 for locking and fixing the rotating plate 2. The top of the base 1 is fixedly connected with a guide rod 10 located on one side of the rotating plate 2, which plays a guiding role for the moving plate 14. The top of the guide rod 10 is fixedly connected with a fixing plate 11. Between the fixing plate 11 and the base 1, a threaded rod 12 is rotatably connected. The top of the threaded rod 12 penetrates out of the fixing plate 11 and is fixedly connected with a rotating handle 13. Between the base 1 and the fixing plate 11, a moving plate 14 is arranged. The moving plate 14 is threadedly connected with the threaded rod 12. The moving plate 14 is slidably connected with the guide rod 10. The bottom of the moving plate 14 is fixedly connected with a detection seat 15 located directly above the right test cup 6. The bottom of the detection seat 15 is provided with three uniformly distributed detection frames 16. The bottom end of each detection frame 16 is provided with a detection head 17 for detecting cement. During detection, by rotating the rotating plate 2, the test cup 6 provided with the stirring assembly 8 is located directly below the detection head 17. Then, through the cooperation of the locking assembly 9 and the limiting block 3 far from the stirring assembly 8, the rotating plate 2 is fixed. Then, water and cement are poured into the test cup 6. Then, through the stirring assembly 8, water and cement are mixed and stirred. After stirring is completed, by driving the threaded rod 12 to rotate through the rotating handle 13, the moving plate 14 is driven to move downward. Then, through the cooperation of the detection seat 15 and the detection frame 16, the detection head 17 is driven to move downward into the test cup 6 to detect the cement.

[0023] Furthermore, at the four corners of the bottom of the base 1, support legs 18 are fixedly connected, which play a supporting role for the base 1. The bottom of the support legs 18 is provided with rubber pads 19, which increase the friction between the bottom end of the support legs 18 and the placement surface, and are beneficial to improving the stability of the device.

[0024] Further, the cleaning assembly 7 includes a first motor 701 fixedly connected to the bottom of the left test cup 6. A first through hole 702 adapted to the first motor 701 is vertically formed at the top of the rotating plate 2. An impeller 703 connected to the output end of the first motor 701 is disposed inside the left test cup 6. The impeller 703 is not on the same axis as the three detection heads 17 and does not contact the impeller 703 when the three detection heads 17 are inside the test cup 6. When the detection heads 17 need to be cleaned, rotate the rotating plate 2 to make the test cup 6 provided with the cleaning assembly 7 located directly below the detection heads 17, then lock and fix the rotating plate 2 through the locking assembly 9, then add clean water into the test cup 6, and then move the detection heads 17 downward through the cooperation of the rotating handle 13, the threaded rod 12 and the moving plate 14 to make the detection heads 17 located inside the test cup 6. Then start the first motor 701 to drive the impeller 703 to rotate. The rotation of the impeller 703 will drive the water flow to rotate, thereby cleaning the cement adhered to the three detection heads 17. After the cleaning is completed, the test cup 6 can be directly taken out and the dirty water in the test cup 6 can be poured out.

[0025] Further, the stirring assembly 8 includes a second motor 801 fixedly connected to the bottom of the right test cup 6. A second through hole 802 adapted to the second motor 801 is vertically formed at the top of the rotating plate 2. A stirring rod 803 connected to the output end of the second motor 801 is disposed inside the right test cup 6. The stirring rod 803 is not on the same axis as the three detection heads 17 and does not contact the stirring rod 803 when the three detection heads 17 are inside the test cup 6. When the cement needs to be detected, rotate the rotating plate 2 to make the test cup 6 provided with the stirring assembly 8 located directly below the detection heads 17, then lock and fix the rotating plate 2 through the locking assembly 9, pour water and cement into the test cup 6, then start the second motor 801 to drive the stirring rod 803 to rotate, mix and stir the water and cement, and then move the detection heads 17 downward through the cooperation of the rotating handle 13, the threaded rod 12 and the moving plate 14 to make the detection heads 17 located inside the test cup 6 to detect the cement.

[0026] Further, the locking assembly 9 includes an L-shaped plate 901 fixedly connected to the top of the base 1. A limit plug 902 adapted to the limit slot 4 is slidably connected to the top of the L-shaped plate 901. A pull block 903 is fixedly connected to the top of the limit plug 902. A first spring 904 is connected between the pull block 903 and the L-shaped plate 901. When it is necessary to fix the rotating plate 2, the pull block 903 is pulled upward to drive the limit plug 902 to move upward, and at the same time, the first spring 904 is stretched. Then, the limit slot 4 on the limit block 3 is aligned with the bottom end of the limit plug 902. Then, the pull block 903 is released, and the first spring 904 will reset and drive the pull block 903 to move downward, inserting into the limit slot 4 to fix the rotating plate 2.

[0027] Further, annular grooves 20 are respectively formed at the near ends of the bottoms of the two test cups 6. A plurality of mounting round grooves 21 corresponding to the annular grooves 20 are formed on the inner wall of the fixing ring 5. A round-headed convex block 22 is slidably connected in each mounting round groove 21. A second spring 23 is connected between one end of the round-headed convex block 22 and the mounting round groove 21. When the test cup 6 is inserted into the fixing ring 5, the cup wall of the test cup 6 will squeeze the round-headed convex block 22 into the mounting round groove 21, and at the same time, the second spring 23 is compressed. When the bottom end of the test cup 6 contacts the top of the rotating plate 2, the annular groove 20 will be aligned with each mounting round groove 21, and at the same time, the second spring 23 will reset, popping the round-headed convex block 22 outwards so that it abuts in the annular groove 20 to fix the test cup 6.

[0028] During use, water and cement are poured into the test cup 6 provided with the stirring assembly 8. At this time, the test cup 6 provided with the stirring assembly 8 is located directly below the detection head 17. Then, the second motor 801 is started to drive the stirring rod 803 to rotate, so as to mix and stir the water and cement. After mixing, the threaded rod 12 is rotated by turning the turning handle 13, so as to drive the moving plate 14 to move downward. Then, the detection head 17 is driven to move downward into the test cup 6 through the cooperation of the detection seat 15 and the detection frame 16 to detect the cement. After the detection is completed, the detection head 17 is raised. Then, the rotating plate 2 is rotated so that the test cup 6 provided with the cleaning assembly 7 is located directly below the detection head 17. The rotating plate 2 is fixed by the locking assembly 9. Then, clean water is poured into the test cup 6. Then, the detection head 17 is moved downward into the test cup 6. By starting the first motor 701 to drive the wave wheel 703 to rotate, the rotation of the wave wheel 703 will drive the water flow to rotate, so as to clean the cement adhered to the three detection heads 17. After the cleaning is completed, the test cup 6 provided with the cleaning assembly 7 can be directly taken out and the dirty water in the cup can be poured out.
