Description

Technical Field

[0001] The utility model relates to the technical field of concrete and mortar detection, in particular to a device for measuring the setting time of concrete and mortar mixtures. Background Technique

[0002] During the concrete detection process, a penetration resistance tester is usually required to ensure the smooth detection of the setting time of concrete and mortar mixtures. The penetrometer mainly consists of a force measuring system, a penetration needle, a loading device, a specimen cylinder, etc. Its working principle is: select a suitable penetration needle according to the penetration resistance of the specimen, insert the penetration needle into the specimen within a certain time, and continuously insert it at a certain time interval, and replace the penetration needle in time to measure the initial setting and final setting time and penetration force of the specimen, and determine the setting performance of the concrete mixture by calculating the penetration force.

[0003] The existing penetration resistance tester uses a lever-type mechanical combination for loading, relying on manual operation. Usually, the setting time of concrete and mortar mixtures is relatively long. Manual operation requires the operator to continuously operate the equipment for a long time, consuming energy and time, and reducing work efficiency. In addition, the speed and stability of loading directly affect the size of the concrete bearing load, and manual operation will cause errors in the experimental results. Content of the Utility Model

Among them, the electric control box 2 is located on the base 1, and a column 11 for installing the loading component 5 is fixed on one side of the base 1. The top of the electric control box 2 forms a support platform. The moving component 3 is located on the support platform, and the moving component 3 is electrically connected to the electric control box 2 to realize the control of the moving component 3. The moving component 3 includes a first guide rail 31 and a second guide rail 32 arranged perpendicular to each other, and the first guide rail 31 is located between the electric control box 2 and the second guide rail 32. In this embodiment, three test mold cups 4 are provided, all of which are located on the second guide rail 32 and are driven by the moving component 3 to move. The loading component 5 is fixed on the top of the column 11, and the probe component 6 is installed at the output end of the loading component 5 and is driven by the loading component 5 to move up and down.

[0033] As Figures 1-2 shown, in this embodiment, a first slider 311 is fixedly connected to the bottom of the second guide rail 32, and the second guide rail 32 is slidably connected to the first guide rail 31 through the first slider 311. A first driving motor 312 is fixed on the upper surface of the first guide rail 31, and its output end is connected to a first lead screw 313. A first sleeve 314 is fixed to the bottom of the second guide rail 32, and the first lead screw 313 is in transmission connection with the second guide rail 32 through the first sleeve 314. Under the control of the electric control box 2, the first driving motor 312 drives the first lead screw 313 to rotate, thereby driving the second guide rail 32 to move precisely on the first guide rail 31. This structure realizes the automatic positioning and adjustment function of the test mold cup 4 in the horizontal direction.

[0034] As Figures 1-2 shown, in this embodiment, a support plate 33 for installing the test mold cup 4 is arranged above the second guide rail 32. The support plate 33 is slidably connected to the second guide rail 32 through a second slider 321. A second driving motor 322 is fixed on the upper surface of the second guide rail 32, and its output end is connected to a second lead screw 323. The second lead screw 323 is movably connected to the support plate 33 through a second sleeve 324, and the second sleeve 324 is fixed to the bottom of the support plate 33. Under the control of the electric control box 2, the second driving motor 322 drives the second lead screw 323 to rotate, thereby driving the support plate 33 to move precisely on the second guide rail 32. This structure realizes the automatic positioning and adjustment function of the test mold cup 4 in the vertical direction. At the same time, in cooperation with the first driving motor 312, it can realize the precise positioning and moving function of the test mold cup 4 in the two-dimensional plane.

Among them, the load sensor 52 is connected to the output end of the telescopic motor 51 through a loading rod 54, and is used to monitor the load change during the penetration process in real time. The displacement sensor 53 is connected to the loading rod 54 and fixed on the column 11, and is used to accurately measure the displacement of the loading rod 54. Through the cooperation of these sensors, accurate control and data acquisition of the loading force value and loading displacement during the penetration process are achieved. In addition, both the load sensor 52 and the displacement sensor 53 are electrically connected to the electric control box 2, so as to control the loading time interval, loading rate, penetration depth, etc.

[0036] As Figure 1 and 4 shown in the figure, the penetrometer assembly 6 includes a fixture 61, a rotating block 62, and three penetrometer needles 63.

Among them, in this embodiment, the driving member 64 is selected as a stepping motor, so that each time the rotating block 62 rotates, it can only rotate the same angle.

[0038] As Figure 4 shown in the figure, in order to absorb the bleeding water on the concrete surface before the test, a water absorption assembly 7 is also installed on one side of the fixture 61.

The water absorption assembly 7 includes a driving cylinder 71 and a suction nozzle. The driving cylinder 71 is fixedly connected to the fixture 61, and the suction nozzle is connected to the output end of the driving cylinder 71.

[0039] As Figure 1 shown in the figure, a control panel 21 is provided on one side of the electric control box 2, which is convenient for the operator to set parameters and control the experiment. At the same time, the electric control box 2 can also receive the data of each sensor, process and analyze it, and finally obtain the experimental results.

[0040] Working principle: Before the setting time is measured, the bleeding water on the surface of the concrete or mortar is sucked away through the suction nozzle. The movement of the second guide rail 32 and the supporting plate 33 is controlled by the electrical components in the electric control box 2 to achieve the precise positioning of the test mold cup 4. The loading assembly 5 drives the penetration needle 63 to move up and down under the instruction of the electrical components in the electric control box 2 to complete the penetration operation. At the same time, the load sensor 52 and the displacement sensor 53 monitor the load and displacement data during the penetration process in real time, and feed these data back to the electric control box 2 for processing, so as to automatically obtain the setting performance data of the concrete mixture and display it through the control panel 21.
