Description

Technical Field

[0001] This utility model relates to the field of testing equipment, and more particularly to an automatic testing equipment for concrete setting time. Background Technology

[0002] Currently, in the field of construction engineering quality testing, the testing of concrete mixture setting time still largely relies on traditional manual operation. This testing process requires testing personnel to systematically collect and record data every half hour, specifically including readings of insertion thermometers, readings of penetration resistance tester values, and observation of the sample surface condition. Due to the characteristics of concrete materials, its setting process typically lasts for several hours, and for high-strength or specially proportioned concrete samples, the setting time may even extend to more than ten hours. This continuous testing requirement forces testing personnel to maintain a long working period, especially during nighttime testing periods, often requiring shift work or continuous individual duty to complete the entire set of tests, placing a double burden on the physical and mental health of testing personnel.

[0003] During manual testing, multiple human factors can interfere with the test results. For example, differences in the standards for determining the end of the penetration resistance test among different testers, slight deviations in the timing of data recording, subjective judgments in observing the surface condition of the sample, and distractions caused by long working hours can all lead to increased dispersion in the test data.

[0004] With the rapid development of digitalization, automation, and intelligent technologies, intelligent equipment is being used more and more widely in the field of engineering construction. Therefore, there is an urgent need to develop an automatic concrete setting time testing device to achieve automatic data acquisition and unmanned operation of the testing process. This would not only eliminate the influence of human factors on the test results, ensuring the impartiality and accuracy of the test data, but also free up technical personnel, save human resources, and improve work efficiency. Utility Model Content

[0005] The present invention aims to overcome the shortcomings of the prior art.

[0006] The technical solution adopted by this utility model is to provide an automatic concrete setting time detection device, including a base, a gantry frame vertically mounted on the base, and a main control console for setting programs to achieve automated testing. A movable support platform is provided on the base, with a cup holder area on one side and a tool area on the other. The cup holder area has test cups for holding cement samples, and the tool area has test fixture components. A clamping mechanism is provided on the gantry frame, and the main control console controls the movement of the clamping mechanism to grab / place the test fixture components. The base includes a fixed outer frame, first linear guides parallel to both sides of the fixed outer frame, and a first drive mechanism located between the two first linear guides. The first drive mechanism drives the movable support platform to move along the first linear guides in the X-axis direction. The gantry frame includes two columns perpendicular to both sides of the base and a crossbeam connecting the two columns. The crossbeam includes second linear guides distributed along the crossbeam and a second drive mechanism located on one side of the second linear guide. The second drive mechanism drives the clamping mechanism to move along the second linear guide in the Y-axis direction. The clamping mechanism includes third linear guides on the left and right sides, a third drive mechanism located between the two third linear guides, and a pneumatic chuck for clamping the test fixture assembly. The third drive mechanism drives the pneumatic chuck to move along the third linear guide in the Z-axis direction.

[0007] The main control console programs control the movements of the first, second, and third drive mechanisms and the pneumatic chuck. The first linear guide rail of the base, in conjunction with the first drive mechanism, drives the moving platform to move back and forth along the X-axis. The second linear guide rail of the gantry frame, in conjunction with the second drive mechanism, drives the clamping mechanism to move left and right along the Y-axis between the cup holder area and the tool area. The third linear guide rail of the clamping mechanism, in conjunction with the third drive mechanism, drives the pneumatic chuck to move up and down along the Z-axis to grab / place the test fixture. This automates the concrete setting test process, replacing manual operation. It completes the entire process, including positioning and switching between the test cup and the test fixture, fixture grabbing / placement, and execution of testing actions. No long-term on-duty personnel are required, solving the problems of continuous operation and overnight testing required by traditional manual testing. This frees up technical personnel and saves human resources. Furthermore, through the program-controlled automated process, the system can automatically complete data collection and recording at set time intervals, avoiding delays or omissions caused by manual operation and ensuring data accuracy.

[0008] Furthermore, the test fixture components include a probe assembly, a cleaning assembly, and a water collection assembly. The probe assembly includes a probe for penetrating the test cup for testing, and a probe holder with a station for loading multiple probes. The main control console controls the clamping mechanism to automatically grab / replace probes from the probe holder, enabling multiple cycles of condensation time detection and continuous penetration testing of multiple sets of samples.

[0009] The cleaning assembly includes an ultrasonic cleaner for cleaning the probe and an air knife drying device located on the outlet side of the ultrasonic cleaner. After the probe is used, the clamping mechanism moves to the cleaning assembly to automatically perform cleaning and drying. The high-frequency vibration of the ultrasonic cleaner thoroughly removes the residual concrete mixture on the surface of the probe, and the air knife drying device further eliminates the residual moisture, preventing the residue from affecting the penetration resistance data of subsequent tests and avoiding the problems of low efficiency or incomplete cleaning of manual cleaning.

[0010] The water collection assembly includes a water collection tank connected to a vacuum pump and a negative pressure pipeline, and a vacuum suction pipe connected to the water collection tank at one end. The vacuum suction pipe is clamped by a clamping mechanism and inserted into the test cup to automatically draw out the oozing water in the test cup, replacing the manual cleaning of the oozing water, avoiding the accumulation of oozing water that changes the humidity or state of the sample, and ensuring the environmental stability of the condensation time test.

[0011] The coordinated processes of "water collection-testing-cleaning," combined with the automatic replacement function of the clamping mechanism, form an automated testing closed loop. This eliminates the need for human intervention, avoiding the inefficiency and human error associated with frequent manual operations in traditional manual testing. It ensures consistent testing conditions and improves the reliability of test data. Furthermore, one end of the probe is a needle for penetrating the cement into the test cup, while the other end has a clamping end for the clamping mechanism. The other end of the vacuum suction tube is a suction port for drawing out exuded water from the test cup, with a clamping end also available for the clamping mechanism.

[0012] Furthermore, the test cup is equipped with a lid at the top. When the lid covers the test cup, it seals the concrete sample, preventing interference from external environmental factors such as dust and humidity changes. This maintains stable humidity and temperature for the sample during the testing process, ensuring consistent sample conditions during penetration resistance testing and thus improving the accuracy of setting time data. The lid also has a clamping end for the clamping mechanism. The clamping end structures of the probe, lid, and vacuum suction tube are identical, allowing the pneumatic chuck to be adapted to only one gripping method to grip / place the probe, lid, and vacuum suction tube without requiring manual switching of clamps or adjustment of gripping parameters, making it simple and convenient.

[0013] Furthermore, the cup holder area includes a tilting mechanism. This mechanism tilts the test cup to one side, causing the bleed water in the concrete sample to naturally converge near one side of the cup. This allows the vacuum suction tube to more efficiently and thoroughly remove the bleed water, preventing residual bleed water from altering the sample's humidity or condition and ensuring the stability of the sample environment during testing. This, in turn, improves the accuracy of setting time data. The tilting mechanism includes a horizontal layer, a tilting layer, and two electric push rods. The horizontal layer is parallel to the base. One side of the tilting layer has a rotating shaft connected to the horizontal layer, and the other side has an extension protruding from the tilting layer. The extension is connected to the two electric push rods. The electric push rods push the extension, causing the tilting layer to rotate and tilt around the rotating shaft. This allows the test cup to automatically tilt to the angle required for bleed water removal according to a programmed setting. After the bleed water is absorbed, the cup returns to a horizontal position, replacing manual adjustment of the cup holder angle. This avoids errors caused by uneven force or positioning deviations, ensuring the smoothness and repeatability of the tilting action.

[0014] Furthermore, the cup holder area can hold multiple test cups of equal size at once, arranged in an array of at least two columns to meet the needs of simultaneous or sequential testing of multiple concrete samples. Different sample groups are switched by moving the X-axis of the mobile support platform, and the cup holder area and tool area are switched by moving the Y-axis of the gantry frame. Combined with the Z-axis movement of the clamping mechanism for gripping / placing, each test cup in the array can be precisely accessed according to a pre-programmed path. During testing, the pneumatic chuck operates sequentially as follows: Clamp the lid open and place it on top of the adjacent test cup lid. The vacuum suction tube is inserted into the test cup to draw up the secreted water and then returned. The probe is inserted into the cement in the test cup to collect data. After clamping, the probe is placed in an ultrasonic cleaner for cleaning. After cleaning, the probe is moved to the air knife drying device for drying. After the probe has been dried, place it back into the probe holder, and then place the cup lid back into place. The clamping mechanism holds the second probe of the probe holder and performs the second test cup test in sequence. The entire process requires no manual operation, ensuring the automation and continuity of the entire "batch testing - data acquisition" process.

[0015] Preferably, there are 6 to 18 test cups, arranged in 3 to 6 columns in the cup rack area, with 3 test cups for each cement sample.

[0016] Preferably, the probe assembly includes 3 to 18 probes of the same and / or different specifications, and a probe holder with a number of workstations matching the number of probes.

[0017] Compared with existing technologies, the advantages of this invention are as follows: By setting a program on the main control console, the coordinated movement of the three-axis (X / Y / Z) moving mechanism and the pneumatic chuck is controlled, realizing fully automated operation of the entire process, including test cup positioning and switching, tooling gripping / placement, and test execution. This eliminates the need for long-term on-duty personnel, completely solving the problems of continuous operation and overnight testing required by traditional manual testing, significantly saving human resources. The program control automatically collects and records penetration resistance data at set time intervals, avoiding delays or omissions caused by manual operation. Simultaneously, the closed-loop design of "water collection-testing-cleaning" eliminates the influence of residual effluent or probe contamination on the test, ensuring consistent test conditions and improving the reliability of condensation time data.

[0018] The clamping end structure of the probe, cup lid, and vacuum suction tube is standardized. The pneumatic chuck only needs to be adapted to one gripping method to complete the gripping / placement of all tooling, without the need for manual switching of fixtures or adjustment of parameters, thus simplifying the operation process.

[0019] The tilting mechanism in the cup holder area automatically tilts the test cup via an electric push rod, causing the oozing water to converge to one side. This, combined with the vacuum suction tube, efficiently absorbs the oozing water, preventing residual oozing water from altering the sample's humidity or condition, ensuring the stability of the testing environment, and further improving data accuracy.

[0020] The cup holder area supports the array placement of multiple test cups, with precise access to each cup via a three-axis moving mechanism. Combined with the multi-spindle carrying capacity of the stylus holder, it can continuously complete the condensation time testing of multiple sets of samples or multiple cycles, achieving fully automated and continuous "batch testing - data acquisition" workflow, significantly improving testing efficiency. The sealed design of the test cup lid prevents interference from external environmental factors such as dust and humidity changes, maintaining stable humidity and temperature of the sample during the testing process, ensuring the uniformity of sample conditions during penetration resistance testing, and further guaranteeing data accuracy.
