Description

Technical Field

[0001] This application relates to the field of concrete setting time measurement technology, and in particular to a fully automatic concrete setting time measurement device. Background Technology

[0002] Concrete setting time (including initial and final setting times) is a core indicator for evaluating concrete workability, directly affecting the project's pouring progress, structural strength development, and construction quality control. According to the "Standard for Test Methods of Ordinary Concrete Mixture Performance" GB / T 50080-2016, traditional setting time testing relies on manual operation: manually removing and placing the sample container lid, changing different sized probes, cleaning the probes, and recording data. This process is not only time-consuming (up to several hours) but also prone to errors due to fluctuations in ambient temperature and humidity, differences in operator experience, and probe insertion angle deviations, making it difficult to meet the demands of modern engineering for testing efficiency and accuracy.

[0003] To overcome the limitations of manual testing, existing technologies have developed some automated equipment. For example, CN221007591U discloses a fully automatic cement mortar and concrete setting time tester, including a sample stage, a frame, a stylus displacement system, a stylus switching system, a sample stabilizing device, a leveling mechanism, a pointer cleaning device, and a constant temperature circulating water device. This device can automatically measure the setting time of cement mortar or concrete samples through the stylus switching system and the stylus displacement device. After the measurement is completed, the stylus is automatically cleaned, and this process is repeated until all samples have been measured. However, this automated measuring device has limited internal space, making it difficult to remove and install the sample cylinder. It also does not consider the removal and installation of the sample cylinder lid or the removal of surface water before testing. Utility Model Content

[0025] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0026] See Figures 1 to 5 This application proposes a fully automatic concrete setting time measuring device, comprising: The machine platform 1 has several support plates 11 arranged side by side. The first side of the support plate 11 is hinged to the machine platform 1. The support plate 11 is provided with a groove 12 for placing a sample barrel 13. The sample barrel 13 has a bleed port on its side wall near the first side of the support plate 11. The moving mechanism 2, located on the machine base 1 and above the sample barrel 13, includes a bracket 21, a first moving component 22, a second moving component 23, a lifting component 24, and a probe mounting head 25. The bracket 21 is slidably engaged with the machine base 1. The first moving component 22 is used to drive the bracket 21 to move along the width direction of the machine base 1. The lifting component 24 is slidably engaged with the bracket 21. The second moving component 23 is used to drive the lifting component 24 to move along the length direction of the machine base 1. The output end of the lifting component 24 is connected to the probe mounting head 25. The probe mounting head 25 integrates an electromagnetic chuck and a pressure sensor. The lifting mechanism 3 is vertically mounted on the machine base 1, and its output end abuts against the second side of the bearing plate 11, which is used to drive the bearing plate 11 to rotate around the hinge axis to tilt the sample barrel 13. The cleaning mechanism 4 is located on one side of the machine base 1 and is used to clean the probe; The barrel lid placement platform 5 is located on one side of the cleaning mechanism 4 and is used to place the iron barrel lid of the sample barrel 13. The probe mounting platform 6 is located between the cleaning mechanism 4 and the bucket lid placement platform 5, and is used to place probes of different specifications. The controller is electrically connected to the moving mechanism 2, the lifting mechanism 3 and the cleaning mechanism 4 respectively. The controller controls the electromagnetic chuck to pick up and release the probe and the iron barrel lid.

[0027] The testing procedure for this fully automatic concrete setting time measuring device is as follows: 1. The operator places the sample bucket 13 containing concrete mortar into the groove 12 of the bearing plate 11, and enters the preset test program (including parameters such as sample number, test interval, initial setting / final setting pressure threshold) through the controller. The operator then calibrates the level of the machine platform 1 through the level adjustment mechanism 7, and then injects water into the cleaning mechanism 4 through municipal water.

[0028] 2. The controller drives the first moving component 22 to move along the width direction and the second moving component 23 to move along the length direction, so that the probe mounting head 25 moves to the top of the test sample barrel 13; then the controller controls the electromagnetic chuck to be energized to pick up the iron barrel lid, the lifting component 24 lifts it up, the moving mechanism 2 moves the barrel lid to the barrel lid placement platform 5 and then de-energizes and releases it.

[0029] 3. The moving mechanism 2 drives the probe mounting head 25 to move to the probe mounting platform 6, according to the current test node (e.g., 20mm probes are selected for the initial setting stage). 2 (Probe), electromagnetic chuck picks up probes of the corresponding specifications; 4. According to the preset coordinates, the controller controls the first moving component 22 to move the probe mounting head 25 to the X coordinate (i.e., the width direction) of the sample barrel 13, and the second moving component 23 to move to the Y coordinate (i.e., the length direction), thus completing the positioning of the test point.

[0030] 5. The lifting assembly 24 descends at a speed of 5 mm / s, inserting the probe vertically into the concrete sample to a depth of 25 mm ± 1 mm; the pressure sensor provides real-time feedback on the insertion resistance, and the controller records the pressure peak and the corresponding time point to determine whether the initial setting / final setting threshold has been reached.

[0031] 6. After the test is completed, the lifting component 24 lifts the probe, and the moving mechanism 2 moves it to the cleaning mechanism 4 for cleaning to remove concrete residue from the surface of the probe. 7. After cleaning, the probe mounting head 25 puts the probe back into the probe mounting platform 6, the electromagnetic chuck is de-energized and released, and then moves to the lid placement platform 5 to pick up the iron bucket lid and put the iron bucket lid back into the sample bucket 13.

[0032] 8. During the initial setting of the concrete sample, the controller starts the lifting mechanism 3, which drives the lifting mechanism 3 to lift the second side of the bearing plate 11, causing the sample bucket 13 to tilt, drain the surface water, and after the drainage is completed, the lifting mechanism 3 performs the reset work, so that the bearing plate 11 is reset to the horizontal state.

[0033] 9. The controller repeats steps 2 to 7 until the final condensation threshold is reached for three consecutive tests. The controller then automatically determines that the test is over, generates a condensation time report, and uploads it to the database.

[0034] 10. After all samples have been tested, the moving mechanism 2 returns to its origin, the cleaning mechanism 4 empties the water tank and disinfects, and the machine 1 automatically shuts off the power, waiting for the next round of testing.

[0035] Through the above technical solution, this application achieves fully unmanned operation of the sample bucket 13 from positioning to data output by integrating multiple modules such as the first moving component 22, the second moving component 23, the lifting component 24, the electromagnetic chuck, the pressure sensor, and the lifting mechanism 3 through the controller. This solves the problems of difficult sample handling, water leakage interference testing, and large human error in traditional equipment. It is especially suitable for batch testing of multiple concrete samples in the laboratory, providing efficient and accurate technical support for engineering quality control.

[0036] Furthermore, the machine base 1 includes a housing, with guide sections extending upward at both ends along the length direction, and the guide sections having openings extending along the width direction, and the support plate 11 located on the upper surface of the housing; The bracket 21 includes a mounting plate 211 and side plates 212 connecting the two ends of the mounting plate 211, and the side plates 212 are embedded in the opening; The first moving component 22 includes a first motor 221, a first gear 222, a first rack 223, a drive shaft 224, and a bearing seat 225. The first motor 221 is located inside the housing. The drive shaft 224 extends along the length of the housing, and its two ends are connected to the top wall of the housing through the bearing seat 225. Driven gears 226 are provided at both ends of the drive shaft 224. The output shaft of the first motor 221 meshes with the driven gears 226 through the first gear 222. A secondary gear 227 is also provided at both ends of the drive shaft 224. The first rack 223 is located at the bottom of the side plate 212 along the width of the housing and meshes with the secondary gear 227.

[0037] Specifically, the machine base 1 is a hollow rectangular shell. Both ends of the shell extend upwards along its length to form guide sections with a height of 150mm. The top end face of each guide section has a strip-shaped opening extending along its width. Support plates 11 are hinged to the upper surface of the shell. Multiple support plates 11 are arranged side-by-side between adjacent guide sections. The bracket 21 includes a horizontally positioned mounting plate 211, which is horizontally positioned above the shell. Side plates 212 are vertically connected to both ends of the mounting plate 211 by bolts. The bottom of each side plate 212 is embedded in the strip-shaped opening of the guide section, slidingly engaging with the inner wall of the opening. To reduce sliding friction between the side plates 212 and the strip-shaped opening, the surface of the side plates 212 can also be coated with grease. The first motor 221 is a stepper motor, and its output shaft can be connected to the first gear 222 via a coupling. The module of the first gear 222 can be set to 1.5 and the number of teeth can be set to 20. The transmission shaft 224 extends along the length of the housing and is made of steel. Both ends are fixed to the inner top wall of the housing via deep groove ball bearing seats 225. The two ends of the transmission shaft 224 are also symmetrically provided with driven gears 226. The module of the driven gears 226 can be set to 1.5 and the number of teeth can be set to 40, which mesh with the first gear 222. To enable the support 21 to move in the width direction of the machine base 1, the two ends of the transmission shaft 224 are also provided with auxiliary gears 227. The module of the auxiliary gears 227 can be set to 1.5 and the number of teeth can be set to 25. The bottom of the side plate 212 is fixed with a first rack 223 by bolts along the width direction of the machine base 1. The length of the first rack 223 is the same as the width of the housing. The auxiliary gears 227 mesh with the first rack 223. Under the drive of the first motor 221, the support 21 is driven to move along the width direction of the housing.

[0038] Furthermore, the second moving component 23 includes a second motor, a second gear, and a second rack; The lifting assembly 24 is provided with a slider, the mounting plate 211 is provided with a slide rail along the length of the housing, the slider is slidably engaged with the slide rail, the second motor is provided on the lifting assembly 24, its output shaft is connected to the second gear, and the second rack is provided on the mounting plate 211 along the length of the housing and meshes with the second gear; The lifting assembly 24 is a first push rod motor.

[0039] Furthermore, a connector with a valve is provided at the oozing outlet, which is connected to the wastewater tank via a conduit. A circular oozing outlet is provided on the side wall of the sample tank 13 facing the hinge shaft. An L-shaped metal connector with a solenoid valve is welded to the oozing outlet, and the outlet is connected to the wastewater tank outside the machine 1 via a PVC flexible hose. The solenoid valve is electrically connected to the controller. When the lifting mechanism 3 raises the support plate 11, the controller simultaneously opens the solenoid valve, and the surface oozing water flows into the wastewater tank by gravity through the hose. After drainage is completed, the solenoid valve automatically closes.

[0040] Through the above technical solution, the linkage control of the solenoid valve and the lifting mechanism 3 eliminates the need for manual emptying of the oozing water, avoiding disturbance to the internal structure of the concrete caused by shaking during the handling of the sample bucket 13, thus ensuring the consistency of the test conditions. At the same time, the drainage through the hose and the collection in the sealed wastewater bucket prevent the oozing water from leaking onto the surface of the machine 1 or the ground, reducing the risk of equipment corrosion and maintaining a clean laboratory environment. Furthermore, the thorough removal of oozing water avoids the pressure value being too low due to contact with the oozing water layer when the probe is inserted, thereby improving the accuracy of the setting time determination results.

[0041] Furthermore, the probe mounting platform 6 is a rectangular metal platform with three circular positioning holes on its surface. The diameters of the three circular positioning holes are 5mm, 8mm, and 11mm, respectively, and the depth is 20mm. The corresponding cross-sectional area of ​​each circular positioning hole is 20mm². 2 50mm 2 100mm 2 The probe has a laser-engraved specification mark next to the positioning hole for easy identification by the controller. The probe mounting platform 6 corresponds to the electromagnetic chuck of the probe mounting head 25. When picking up or placing the probe, the electromagnetic chuck is energized to attract the top of the probe handle and is released when the power is turned off.

[0042] Furthermore, the lifting mechanism 3 is a second push rod motor, and its output end is provided with an arc-shaped top block, the material of which is wear-resistant rubber.

[0043] Furthermore, the cleaning mechanism 4 includes a water tank, a brush assembly, and a waterproof motor. The water tank is located on one side of the machine base 1, and the waterproof motor is located inside the water tank. Its output shaft is connected to the brush assembly for transmission. The brush assembly has a hollow cavity adapted to the probe, and the inner wall of the hollow cavity is provided with spiral nylon bristles.

[0044] Furthermore, the brush assembly includes a bracket 21 and a brush tube. The output shaft of the waterproof motor is coaxially connected to the bracket 21, and the brush tube is detachably connected to the bracket 21 via a snap-fit ​​structure.

[0045] Furthermore, the device also includes a leveling mechanism 7, which comprises a screw lifting support and a digital bubble level. The screw lifting support is symmetrically arranged at the four corners of the bottom of the machine base 1. The screw lifting support consists of a screw, a nut, and an adjusting handwheel. The nut is welded to the bottom of the housing, and the outer peripheral wall of the adjusting handwheel has anti-slip texture. Rotation adjusts the force, which drives the screw to rise and fall, thereby causing local height changes in the machine base 1, and the leveling of the machine base 1 is completed by the bubble level.

[0046] Furthermore, the device also includes a transparent chamber, which has a closed cavity for accommodating the machine tool 1, and a transparent cover that can be flipped open and closed on the top. The side walls of the transparent chamber are provided with a number of ventilation holes arranged in a matrix, and a temperature regulation component is provided inside the closed cavity.

[0047] In this embodiment, the transparent chamber is primarily used to simulate a constant temperature environment. The transparent chamber is placed indoors and works in conjunction with the indoor air conditioning system to achieve a constant temperature setting, reducing the interference of external temperature on the concrete's setting and thus providing a stable testing environment for concrete setting. The transparent chamber is connected to the outside through ventilation holes. The chamber is made of acrylic and has multiple ventilation holes arranged in a matrix on its surface. In a preferred embodiment, the diameter of the ventilation holes is 8mm to 12mm. These multiple ventilation holes effectively reduce the velocity of gas entering the sealed chamber, allowing the gas to enter at a lower speed, simulating a natural heat dissipation environment. In cold environments, for example, when the indoor temperature is 5°C, the transparent chamber achieves a constant temperature environment through its own regulating components. In hot environments, for example, when the indoor temperature is 35°C, the indoor temperature is adjusted to 16°C by the air conditioning system, and then a constant temperature environment of 20°C is achieved through the regulating components.

[0048] Furthermore, the temperature regulation component includes a thermocouple, a control unit, and a heater. The thermocouple is used to detect the real-time temperature inside the cavity. After receiving the real-time temperature signal, the control unit controls the heater to operate so that the cavity temperature is maintained at the preset condensation temperature.

[0049] In this embodiment, thermocouples are installed inside a closed cavity, transmitting the detected real-time temperature to a control unit. Upon receiving the real-time temperature, the control unit, if the real-time temperature is lower than a preset temperature, controls the heater to heat the cavity until the real-time temperature reaches the preset temperature. In practice, the thermocouples can freely extend and retract, and can be installed at different positions within the closed cavity according to its installation requirements. The number of thermocouples can be determined based on the size of the closed cavity. It is understood that the heater is existing technology and will not be described further here.

[0050] Through the above technical solutions, the transparent chamber can isolate external temperature fluctuations, ensuring that the concrete setting process takes place in a standard environment, which can reduce the error in setting time testing.

[0051] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
