Different types of cements have different curing times after being mixed at a certain temperature. Therefore, it is necessary to detect the curing times of different types of cements. Existing penetrometers are usually used to measure the consistency or viscosity of substances such as petroleum products and asphalt, as well as the consistency or viscosity of other liquids or semi-solid substances, and cannot detect the curing time of cement. Therefore, it is very necessary to design a penetrometer for detecting the curing time of cement. Content of the Utility Model

[0022] Please refer to Figure 1-2 , the present invention provides a technical solution: a penetrometer, including a base 1, and a support base 2 is fixedly installed on the top of the base 1;
[0023] An XY-axis moving fine-tuning platform 3 is provided on the top of the support base 2. The XY-axis moving fine-tuning platform 3 includes an X-direction moving plate 31. The X-direction moving plate 31 is located on the top of the support base 2. A first manual handwheel 33 is provided on one side of the X-direction moving plate 31. The first manual handwheel 33 is used to control the left and right movement of the X-direction moving plate 31. A Y-direction moving plate 32 is bolted above the X-direction moving plate 31. A second manual handwheel 34 is provided on one side of the Y-direction moving plate 32. The second manual handwheel 34 is used to control the front and back movement of the Y-direction moving plate 32;
[0024] A top plate 4 is fixedly connected to the top of the Y-direction moving plate 32. The top plate 4 moves together with the Y-direction moving plate 32. A fixing groove is provided inside the top plate 4. A pressing column is clamped inside the fixing groove. The pressing column is divided into a first pressing column 5 and a second pressing column 6. The first pressing column 5 is cylindrical in shape. The mass of the first pressing column 5 is 398 - 402 g. A first pressing head 51 is fixedly installed at the bottom of the first pressing column 5. The diameter of the first pressing head 51 is 0.9 - 1.1 mm. The first pressing column 5 is used to press cured cement, permanent cement, and cement for lining and temporary filling. The mass of the second pressing column 6 is 99.5 - 100.5 g. A second pressing head 61 is fixedly installed at the bottom of the second pressing column 6. The diameter of the second pressing head 61 is 1.9 - 2.1 mm. The second pressing column 6 is used to press uncured cement and cavity lining cement.
[0025] A groove 7 is also provided on the top of the base 1. A glass sheet 8 is placed inside the groove 7. A metal mold 9 is provided above the glass sheet 8. A round hole is provided inside the metal mold 9 for placing cement. The round hole is located below the first pressing head 51. The first pressing head 51 is used to press the cement tightly inside the round hole;
[0026] A plurality of fixing bolts 10 are respectively provided on both sides of the groove 7. The fixing bolts 10 are threadedly connected to the top of the base 1. The lower surface of the screw head of the fixing bolt 10 is located on both sides of the metal mold 9. The fixing bolts 10 are used to fix the metal mold 9.
[0027] Working principle:
[0028] When it is necessary to measure the setting time of the setting cement, the permanent cement for cementation, and the cement for lining and temporary filling, the operator snaps the first pressing column 5 into the groove of the top plate 4. Subsequently, the mixed cement is placed inside the round hole of the metal mold 9. By means of the XY-axis moving fine-tuning platform 3, the first pressing head 51 is positioned directly above the cement. The metal mold 9 is fixed by using the fixing bolt 10 to press the metal mold 9. The first pressing head 51 is vertically lowered to the surface of the cement. The cement is observed every 15 s, and the surface of the cement without indentation is continuously pressed until the setting time of the cement is reached. The time recorded by the operator from the start of mixing the cement until the first pressing head 51 cannot completely penetrate the 2-mm specimen of the cement is the setting time.
[0029] When it is necessary to measure the setting time of the non-setting cement and the cavity lining cement, the operator snaps the second pressing column 6 into the groove of the top plate 4. Subsequently, the mixed cement is placed inside the round hole of the metal mold 9. By means of the XY-axis moving fine-tuning platform 3, the second pressing head 61 is positioned directly above the cement. The metal mold 9 is fixed by using the fixing bolt 10 to press the metal mold 9. The second pressing head 61 is vertically lowered to the surface of the cement and pressed once every 15 min for a total test time of 1 h. The operator observes the penetration of the cement with the naked eye under the light. When the cement is completely penetrated within 1 h, that is the setting time.
