[0002] Mortar coagulation refers to the process in which the water in the mortar gradually reacts with cement to form a hardened body, causing the mortar to gradually solidify and harden. This process includes the hydration reaction of cement, the reaction of cement particles with sand, water and other admixtures, and the evaporation of water. By monitoring the coagulation time, it can be ensured that the quality of the mortar meets the requirements and avoid quality problems caused by insufficient early coagulation or delayed coagulation. Generally, a time meter is used for detection. The time meter is a device used to test parameters such as time, temperature and pressure during the coagulation process of materials such as mortar and concrete. In the mortar coagulation process, it is very important to understand the time parameters because they affect the strength, stability and durability of the mortar.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0031] Reference Figure 1 and Figure 2, the utility model provides an embodiment: a mortar setting time measuring instrument, including a chassis 1, a vertical rod 2 is fixedly connected to the upper surface of the chassis 1, a limiting assembly is arranged on the upper surface of the chassis 1, a rack 4 is fixedly connected to the side wall of the vertical rod 2, a connecting ring 5 is slidably connected to the side wall of the vertical rod 2, a fixing frame 6 is fixedly connected to the side wall of the connecting ring 5, a rotating shaft 7 is rotatably connected inside the fixing frame 6, a gear 8 is fixedly connected to the side wall of the rotating shaft 7, a worm gear 9 is fixedly connected to the side wall of the rotating shaft 7, a motor 10 is fixedly connected to the side wall of the fixing frame 6, a worm 11 is fixedly connected to the output end of the motor 10, the worm 11 is meshed with the worm gear 9, the gear 8 is meshed with the rack 4, a fixing plate 12 is fixedly connected to the side wall of the connecting ring 5, a test needle 13 is arranged inside the fixing plate 12, and a limiting assembly includes a limiting slot plate 3, a lower surface of the limiting slot plate 3 is fixedly connected to the upper surface of the chassis 1, and a side wall of the connecting ring 5 is slidably connected to the side wall of the limiting slot plate 3.
[0032] When the test mold 27 is accurately placed, the worm 11 is driven to rotate by starting the motor 10. Since the worm 11 is meshed with the worm wheel 9, when the worm 11 rotates, the worm wheel 9 will also rotate accordingly. The rotation of the worm wheel 9 then drives the rotation of the shaft 7. With the rotation of the shaft 7, the gear 8 also starts to rotate. The meshing relationship between the gear 8 and the rack 4 enables the rotation of the gear 8 to drive the rack 4 to move linearly, thereby causing the connecting ring 5 to slide on the vertical rod 2. This sliding not only ensures the stability of the movement, but also ensures that the test needle 13 can be accurately inserted into the interior of the test mold 27.
[0033] Reference Figure 3 The side wall of the limit slot plate 3 is fixedly connected with a cover plate 14, and an electric slide rail 15 is arranged on the lower surface of the cover plate 14. A slider 16 is slidably connected inside the electric slide rail 15. The side wall of the test needle 13 is slidably connected inside the cover plate 14. A fixed frame 17 is fixedly connected to the lower surface of the slider 16. A motor 18 is fixedly connected to the side wall of the fixed frame 17. A worm 19 is fixedly connected to the output end of the motor 18. A rotating column 20 is rotatably connected inside the fixed frame 17. A worm gear 21 is fixedly connected to the side wall of the rotating column 20. The worm gear 21 is meshed with the worm 19. A connecting plate 22 is fixedly connected to the side wall of the connecting plate 22. A splint 24 is rotatably connected to one side of the connecting plate 22. A connecting plate 23 is rotatably connected to the inside of the fixed frame 17. One side of the connecting plate 23 is rotatably connected to the side wall of the splint 24. A dial 25 is fixedly connected to the upper surface of the chassis 1. A base 26 is fixedly connected to the upper surface of the dial 25. A test mold 27 is arranged on the upper surface of the base 26.
[0034] When the device is used for work, first, the fixed frame 17 needs to be moved to the front side of the cover plate 14 by the electric slide rail 15, then the test mold 27 is placed between the clamping plates 24, and then the worm 19 is driven to rotate by starting the motor 18. The motor 18, as the power source of the device, provides stable power for the rotation of the worm 19. The worm 19 is meshed with the worm wheel 21, thereby converting the rotation of the worm 19 into the rotation of the rotating column 20, so that the rotating column 20 rotates inside the fixed frame 17. The rotation of the rotating column 20 not only drives the connecting plate 1 22 to deflect, but also makes the clamping plate 24 move in the direction of the test mold 27 under the restriction of the connecting plate 23, thereby achieving the clamping and fixing of the test mold 27. Finally, the fixed frame 17 is reset by the electric slide rail 15, and the test mold 27 is placed on the surface of the base 26, and the cover plate 14 covers the surface of the test mold 27.
[0035] Working principle: When the device is used, first, the fixed frame 17 is moved to the front side of the cover plate 14 by the electric slide rail 15, and then the test mold 27 is placed between the clamping plates 24. At this time, the motor 18 is started to drive the worm 19 to rotate. When the worm 19 rotates, it will drive the worm wheel 21 to rotate, so that the rotating column 20 rotates inside the fixed frame 17. When the rotating column 20 rotates, it will drive the connecting plate 1 22 to deflect, and under the restriction of the connecting plate 23, the clamping plate 24 moves inward to clamp and fix the test mold 27. At this time, the fixed frame is driven by the electric slide rail 15. The second 17 is reset, so that the test mold 27 is placed on the surface of the base 26, and the cover plate 14 covers the surface of the test mold 27. After the placement is completed, the worm 11 is driven to rotate by starting the motor 10. Under the action of the meshing of the worm 11 and the worm wheel 9, the rotation of the worm 11 will drive the worm wheel 9 to rotate, thereby rotating the shaft 7, and then driving the gear 8 to rotate. Because the gear 8 is meshed with the rack 4, when the gear 8 is rotating, it will drive the connecting ring 5 to slide on the vertical rod 2, and finally the test needle 13 is inserted into the interior of the test mold 27 to detect the coagulation degree of the mortar.
[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
