Technical Field

[0001] The present invention belongs to the technical field of cement detection, and particularly relates to a detection device capable of timing the monitoring of the setting time of cement and a monitoring method thereof. Background Art

[0002] Cement is a powdery substance and belongs to hydraulic cementitious materials. It can not only harden in the air, but also continue to harden in water and maintain strength and volume stability. After being mixed with water and stirred, it forms a plastic paste, which can harden in the air or in water and firmly cement materials such as sand and stone together. It is widely used in civil engineering, construction, road construction and other fields, and is a basic component of building materials such as concrete and mortar.

[0003] Since the hardening and setting of cement are its basic characteristics, in the detection of cement, it is necessary to detect the hardening and setting time of cement to clearly know the specific setting characteristics of cement.

[0004] The existing detection method generally involves inserting a test needle into the concrete by the tester. However, manual operation has uncertainties and non-standardizations, which will lead to deviations in the test results. Moreover, when there are many test samples, the labor intensity of the staff is large and the test efficiency is low. Summary of the Invention

[0005] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a detection device capable of timing the monitoring of the setting time of cement and a monitoring method thereof.

[0006] To achieve the above technical purpose, the technical solution adopted by the present invention is as follows:

[0007] In the first aspect, the present invention provides a detection device capable of timing the monitoring of the setting time of cement, including a test chamber, a setting time cylinder, and a test controller;

[0010] Further defined, the test mechanism includes a plurality of test needles with different needle tip areas. With such a structural design, test needles with different needle tip areas can be selected according to different penetration strength values.

[0011] It is further defined that the setting time cylinder includes a cylinder body and a cylinder cover, and the side wall of the cylinder body is provided with a weeping hole. With such a structural design, the weeping hole is designed mainly to remove the weeding water on the surface of the concrete sample, and the cylinder cover is used to seal the cylinder body when testing is not required.

[0012] It is further defined that the turntable is provided with a plurality of third mounting holes distributed in an annular pattern, the hole walls of the third mounting holes are provided with threads, the turntable is provided with a water collecting seat at the position of the third mounting holes, the water collecting seat is provided with a seat cup for accommodating the cylinder body, the outer surface bottom of the seat cup is provided with a hollow externally threaded tube, the externally threaded tube is adapted to the threads on the third mounting holes, and the externally threaded tube is connected to the inside of the seat cup. With such a structural design, the seat cup of the water collecting seat can, on the one hand, limit the installation position of the condensation time cylinder, and on the other hand, can collect the water discharged from the water secretion hole to prevent the water from escaping everywhere and polluting the detection environment. The third mounting hole is used to install the water collecting seat, and the externally threaded tube under the seat cup is used to drain the collected water.

[0013] It is further defined that the upper edge of the seat cup is turned outward to form an arc edge. With such a structural design, the arc edge can expand the water receiving range and gather and guide the water, so that the water discharged from the outer wall of the cylinder is introduced into the seat cup through the arc edge.

[0014] It is further defined that the lower edge of the externally threaded pipe is connected to a water pipe. With such a structural design, the water pipe guides the gathered water to a predetermined collection position.

[0015] It is further defined that the turntable is provided with a carrier, a first protective cover located on the lower surface of the carrier, the bottom surface of the inner cavity of the test box forms a second protective cover by an upward protrusion, the first protective cover and the second protective cover are plugged in and matched, the second protective cover is located in the inner cavity of the first protective cover, the rotating power source is fixed by the test box, and is located in an enclosed cavity formed by the first protective cover and the second protective cover. With such a structural design, the second protective cover and the second protective cover are plugged in, which facilitates the installation of the turntable from top to bottom on the test box. The second protective cover can also limit the installation position of the turntable, and the first protective cover and the second protective cover can protect the internal rotating power source.

[0016] It is further defined that a connection seat for connecting to a rotating power source is provided at the center position of the lower surface of the carrier. With such a structural design, the connection seat is used to connect to the output end of the rotating power source.

Under the elastic force of the springs, the bull's-eye ball bearings are in contact with the outer wall of the second protective cover; the first protective cover is provided with second mounting holes at the hem, and casters are installed at the positions of the second mounting holes. The inner cavity bottom surface of the test chamber forms an annular raceway for the casters to travel through a downward depression. With such a structural design, the hem provides an installation position for the casters, the casters carry the entire turntable, the annular raceway can standardize the movement track of the casters and maintain the stability of the caster movement, thereby improving the stability of the turntable rotation. Under the elastic force of the springs, the bull's-eye ball bearings are in contact with the outer wall of the second protective cover. When the turntable starts to rotate, the first protective cover moves relative to the second protective cover, and the bull's-eye ball bearings can prevent the direct contact and friction between the outer wall of the second protective cover and the inner wall of the first protective cover. Such friction will cause abnormal noises and hinder the smooth rotation of the turntable.

[0018] Second, the present invention provides a monitoring method, which uses the above-mentioned detection device capable of regularly monitoring the setting time of cement to monitor the setting time of cement.

The embodiments described herein are specific specific embodiments of the present invention for explaining the concept of the present invention; these descriptions are all explanatory and exemplary, and should not be construed as a limitation on the embodiments of the present invention and the protection scope of the present invention. Except for the embodiments described herein, those skilled in the art can also adopt other obvious technical solutions based on the content disclosed in the claims and the specification of this application, and these technical solutions include technical solutions that make any obvious substitutions and modifications to the embodiments described herein.

[0039] Example 1

[0040] As shown in the figure, this embodiment provides a detection device for timing the setting time of cement, including a test chamber 1, a setting time cylinder 6, and a test controller;

[0041] A turntable 2 with a horizontal rotation degree of freedom is provided at the bottom of the inner cavity of the test chamber 1. The turntable 2 is connected to a rotary power source 3, and the setting time cylinder 6 is carried by the turntable 2;

[0042] On the side wall of the test chamber 1, a first manipulator 81, a second manipulator 82 and an ultrasonic cleaning box 7 are installed, and a testing mechanism 9 is installed at the execution end of the first manipulator 81.

[0043] In this embodiment, several setting time cylinders 6 are placed on the surface of the turntable 2, and the cement to be tested is placed inside the setting time cylinder 6. At set time intervals, the rotary power source 3 drives the turntable 2 to rotate, so that the setting time cylinders 6 at different positions are rotated to the test position for testing by the testing mechanism 9;

[0044] During testing, driven by the first manipulator 81, the testing mechanism 9 is inserted into the cement for testing, and parameters such as the detected pressure value, temperature, and humidity are fed back to the test controller. The test controller records the time itself. As time goes by, the cement will harden and its hardness will also change. By the change of the pressure value of the cement in the setting time cylinder 6 fed back by the testing mechanism 9 over time, the hardening setting time of the cement can be obtained;

[0045] After the test is completed, the first manipulator 81 drives the testing mechanism 9 into the ultrasonic cleaning box 7 to clean the testing mechanism 9 for the next use, while the rotary power source 3 drives the turntable 2 to rotate, so that the sample in the next setting time cylinder 6 is rotated to the test position;

[0046] The second manipulator 82 is used to perform the opening and closing actions of the setting time cylinder 6. Before the test, the second manipulator 82 opens the setting time cylinder 6, and after the test is over, the second manipulator 82 closes the setting time cylinder 6;

[0047] In some optional examples, the rotary power source 3 is selected as a servo motor. Since the servo motor has closed-loop control and high precision, it can more accurately determine the rotation angle of the turntable 2;

[0048] The present invention can realize the automatic detection of cement, with a high degree of automation, can avoid the deviation of the detection results caused by the non-standard detection operations of manual workers, and moreover, the turntable 2 can rotate according to the test interval to ensure that different samples are conveyed to the test position for sequential measurement, which is beneficial to reducing the work burden of the detection personnel.

[0051] In this embodiment, test needles with different needle areas can be selected according to different penetration strength values. In some alternative examples, the testing mechanism 9 includes a first test needle 91, a second test needle 92, and a third test needle 93; the needle area of the first test needle 91 is 100 mm 2 , the needle area of the second test needle 92 is 50 mm 2 , and the needle area of the third test needle 93 is 20 mm 2 .

[0052] Example 3

[0054] In this embodiment, the design of the water seepage hole 611 is mainly to exclude the water seepage on the surface of the concrete specimen. The cylinder cover 62 closes the cylinder body 61 when testing is not required. The picking-up and placing actions of the cylinder cover 62 are implemented by the second manipulator 82.

[0055] Example 4

[0056] As shown in the figure, this embodiment provides a detection device for timing the monitoring of the setting time of cement. The difference from Embodiment 3 is that in this embodiment, it is defined that the turntable 2 is provided with a number of annularly distributed third mounting holes 211. The hole wall of the third mounting hole 211 is provided with threads. A water collection seat 5 is installed at the position of the third mounting hole 211 on the turntable 2. The water collection seat 5 is provided with a seat cup 51 for accommodating the cylinder body 61. A hollow external threaded pipe 52 is provided at the bottom of the outer surface of the seat cup 51. The external threaded pipe 52 is adapted to the threads on the third mounting hole 211, and the external threaded pipe 52 is connected to the inside of the seat cup 51; the upper edge of the seat cup 51 forms an arc edge 53 by turning outwards; a water guide pipe 54 is connected to the lower edge of the external threaded pipe 52.

[0057] In this embodiment, on the one hand, the seat cup 51 of the water collection seat 5 can define the installation position of the setting time cylinder 6, and on the other hand, it can centrally collect the water discharged from the water seepage hole 611 to avoid the water from escaping everywhere and polluting the detection environment. The third mounting hole 211 is used to install the water collection seat 5, and the external threaded pipe 52 below the seat cup 51 is used to export the collected water;

[0058] The arc edge 53 can expand the water receiving range and conduct and guide the water, so that the water discharged from the lower part of the outer wall of the cylinder body 61 is introduced into the seat cup 51 by the arc edge 53;

[0059] The water guide pipe 54 then exports the converged water to a predetermined collection position.

[0060] Example 5

[0061] As shown in the figure, this embodiment provides a detection device for timing and monitoring the setting time of cement. Different from Embodiment 1, this embodiment defines that the turntable 2 is provided with a carrier 21 and a first protective cover 22 on the lower surface of the carrier 21. The bottom surface of the inner cavity of the test chamber 1 forms a second protective cover 11 through an upward protrusion. The first protective cover 22 and the second protective cover 11 are inserted and matched. The second protective cover 11 is located inside the inner cavity of the first protective cover 22. The rotary power source 3 is fixed through the test chamber 1 and is located in the enclosed cavity formed by the enclosure of the first protective cover 22 and the second protective cover 11;

[0062] A connecting seat 23 for connecting with the output end of the rotary power source 3 is provided at the central position of the lower surface of the carrier 21;

[0063] The lower edge of the first protective cover 22 is provided with an outwardly turned hem 24. A number of first mounting holes 221 are provided on the inner wall of the first protective cover 22 at the height position corresponding to the second protective cover 11. A spring 42 and a ball bearing 43 are installed in the first mounting holes 221. Under the elastic force of the spring 42, the ball bearing 43 contacts the outer wall of the second protective cover 11; the first protective cover 22 is provided with a second mounting hole 241 at the hem 24, and a caster 41 is installed at the position of the second mounting hole 241. The bottom surface of the inner cavity of the test chamber 1 forms an annular raceway 12 for the caster 41 to travel through a downward depression.

[0064] In this embodiment, the insertion of the second protective cover 11 and the second protective cover 11 facilitates the installation of the turntable 2 onto the test chamber 1 from top to bottom. The second protective cover 11 can also limit the installation position of the turntable 2. The enclosure of the first protective cover 22 and the second protective cover 11 can protect the internal rotary power source 3;

[0065] The connecting seat 23 is used to connect with the output end of the rotary power source 3;

[0066] The hem 24 provides the installation position for the caster 41. The caster 41 bears the entire turntable 2. The annular raceway 12 can standardize the movement track of the caster 41 and maintain the stability of the movement of the caster 41, thereby improving the rotation stability of the turntable 2. Under the elastic force of the spring 42, the ball bearing 43 contacts the outer wall of the second protective cover 11. When the turntable 2 starts to rotate, the first protective cover 22 moves relative to the second protective cover 11. The ball bearing 43 can prevent the direct contact and friction between the outer wall of the second protective cover 11 and the inner wall of the first protective cover 22. This kind of friction will cause abnormal noise and hinder the smooth rotation of the turntable 2.

[0067] The above embodiments are only used to exemplarily illustrate the principles and effects of the present invention, rather than to limit the present invention. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present invention.
