Description

Technical Field

[0001] This invention relates to the field of initial setting test technology for cementitious materials, specifically to a fully automatic device for testing initial setting. Background Technology

[0002] Currently, in the field of initial setting time testing of cementitious materials, especially concrete and gypsum, the determination of initial setting time is basically done manually by preparing the slurry. Although initial setting time testing equipment exists on the market, its level of intelligence, versatility, and automation is low, which cannot effectively improve the efficiency of initial setting time testing of cementitious materials. On the one hand, the existing testing equipment has too long a measurement interval, making it unsuitable for products with short and unstable initial setting times; on the other hand, the existing testing equipment has a low level of automation, requiring highly skilled operators and unable to achieve fully automated testing operations. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a fully automatic device for measuring initial setting time, which addresses the above-mentioned shortcomings.

[0004] To solve the above technical problems, the present invention adopts the following technical solution:

[0005] A fully automatic device for measuring initial setting time, comprising:

[0006] Measuring rod,

[0007] A first lifting assembly is provided with an adsorption unit, which can engage or disengage with the measuring rod. The first lifting assembly is used to drive the adsorption unit to rise or fall.

[0008] The second lifting component can drive the measuring rod to rise or fall when the adsorption unit separates from the measuring rod.

[0009] A triggering unit is used to separate the adsorption unit from the probe when the first lifting assembly moves the probe to a preset position;

[0010] A ranging unit is used to detect the height of the measuring rod.

[0011] Furthermore, the second lifting assembly is provided with a guide unit, which is used to guide the falling of the measuring rod.

[0012] Furthermore, the second lifting assembly is equipped with a rotary assembly, which can drive the measuring rod to rotate horizontally around the first axis to change the contact position between the measuring rod and the cementitious material to be tested.

[0013] Furthermore, the rotary assembly includes a first drive mechanism, a rotating shaft, and a rotary table. The rotating shaft is rotatably mounted on a second lifting assembly, and the rotary table is mounted on the rotating shaft. The rotary table has a through hole that mates with a measuring rod. The top end of the measuring rod has a limiting part for restricting the measuring rod from passing through the through hole. The first drive mechanism is mounted on the second lifting assembly and is used to drive the rotating shaft and the rotary table to rotate horizontally.

[0014] Furthermore, a cleaning component is provided on the second lifting component or rotating component. When the adsorption unit is attracted to the measuring rod, the second lifting component can drive the cleaning component to rise or fall along the outer wall of the measuring rod.

[0015] Furthermore, the cleaning assembly includes a second drive mechanism, an outer sleeve, an inner sleeve, and hinges. The second drive mechanism and the outer sleeve are both mounted on the second lifting assembly or the rotating assembly. The inner sleeve is rotatably mounted inside the outer sleeve, and the measuring rod is located inside the inner sleeve. The outer sleeve has at least two sliding grooves, and the hinges are mounted in the sliding grooves. The inner sleeve and the hinges have mutually cooperating helical structures. The second drive mechanism is used to drive the inner sleeve to rotate and drive all the hinges to move radially along the measuring rod, so that the hinges abut against or move away from the measuring rod.

[0016] Furthermore, the adsorption unit includes an electromagnet, and a magnet is provided at the top of the measuring rod.

[0017] Furthermore, it also includes an automatic molding assembly, which includes a test mold with an opening at the top. The automatic molding assembly is used to inject a preset volume of the gelling material to be tested into the test mold.

[0018] Furthermore, the automatic mold-making assembly includes a first moving mechanism, a second moving mechanism, and a material conveying pipe, wherein the material conveying pipe is connected to the input end of the trial mold;

[0019] The first moving mechanism is used to move the valve plate to close or open the input end of the test mold;

[0020] The second moving mechanism is used to move the scraper to scrape off excess cementitious material above the mold.

[0021] Furthermore, the ranging unit is also used to detect the liquid level height of the gelling material to be tested within the test mold.

[0022] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0023] (1) The present invention uses two lifting devices to lift and release the measuring rod. By setting a trigger unit and a distance measuring unit, the measuring rod can be automatically released and the depth of the measuring rod inserted into the cementitious material to be tested can be recorded, thereby determining whether the cementitious material to be tested has reached the initial setting state, so as to realize the automatic measurement of initial setting, simplify the initial setting time measurement process, and improve the measurement efficiency.

[0024] (2) By setting up a rotating component, the present invention can change the falling position of the test rod in multiple test processes to avoid the test rod falling into the hole in the cementitious material to be tested, thereby improving the accuracy of the test results;

[0025] (3) By setting up a cleaning component, the present invention can clean the residual cementitious material to be tested on the outer wall of the test rod before each test operation, thereby completing the cleaning of the test rod and further improving the accuracy of the test results;

[0026] (4) By setting up an automatic molding component, the present invention can automatically introduce the initial set material to be tested into the mold, thereby improving the automation level of the device.

[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0052] Example 1

[0053] like Figure 1 and Figure 2 As shown, a fully automatic device for measuring initial condensation includes: a measuring rod 1, a first lifting assembly 2, a second lifting assembly 3, a triggering unit 4, a distance measuring unit 6, and a housing 8.

[0054] like Figure 11 The measuring rod 1 includes a magnet 12, a rod body, and a needle body arranged sequentially from top to bottom. In this embodiment, the magnet 12 is a limiting part 11, which is used to restrict the top end of the measuring rod 1 from passing through the through hole 3131.

[0055] The first lifting assembly 2, the second lifting assembly 3, the triggering unit 4, and the ranging unit 6 are all mounted on the housing.

[0056] Both the first lifting assembly 2 and the second lifting assembly 3 include a guide rail, a slider, a lead screw, and a motor. The slider is mounted on the guide rail and can move along the guide rail. The lead screw is rotatably mounted on the guide rail. The output end of the motor is connected to the lead screw. The slider is provided with a nut that cooperates with the lead screw. When the motor drives the lead screw to rotate, it can drive the slider to move along the guide rail.

[0057] The slider of the first lifting assembly 2 is provided with a first mounting bracket 22, and the first mounting bracket 22 is provided with an adsorption unit 2a. In this embodiment, the adsorption unit 2a is an electromagnet 21, and the top end of the measuring rod 1 is provided with a magnet 12. The first lifting assembly 2 is used to drive the electromagnet 21 to rise or fall, and the electromagnet 21 can attract the measuring rod 1 through the magnet 12.

[0058] like Figure 4 and Figure 6 As shown, the trigger unit 4 is disposed on the first mounting bracket 22. The trigger unit 4 includes a liquid level positioning rod 41 and a position sensor 42. The liquid level positioning rod 41 is vertically disposed below the first mounting bracket 22, and the position sensor 42 is disposed on the first mounting bracket 22. When the liquid level positioning rod 41 contacts the top of the test mold 71, it will trigger the position sensor 42, thereby de-energizing the electromagnet 21 and separating the electromagnet 21 from the measuring rod 1.

[0059] like Figure 3 and Figure 4As shown, the second lifting assembly 2 is equipped with a rotating assembly 31 and a cleaning assembly 32.

[0060] The second lifting assembly 2 has a second mounting bracket 33 on its slider;

[0061] like Figure 5 As shown, the rotary assembly 31 includes a first drive mechanism 311, a rotating shaft 312, and a rotating table 313. The first drive mechanism 311 is mounted on a second mounting bracket 33. The rotating shaft 312 is rotatably mounted on the second mounting bracket 33 and is in a vertical state. The rotating table 313 is horizontally mounted at the bottom of the rotating shaft 312 and is coaxial with the rotating shaft 312. The output end of the first drive mechanism 311 is connected to the rotating shaft 312. The first drive mechanism 311 can drive the rotating shaft 312 and the rotating table 313 to rotate horizontally. The rotating table 313 has a through hole 3131 that cooperates with the measuring rod 1. The top end of the measuring rod 1 is provided with a limiting part 11 for limiting the measuring rod 1 from passing through the through hole 3131. The rotating table 313 is provided with a micro switch 3132 for triggering the ranging unit 6 to detect the height of the measuring rod 1.

[0062] like Figure 7 and Figure 8 As shown, the cleaning component 32 includes a second drive mechanism 321, an outer sleeve 322, an inner sleeve 323, and a hinge 324. The second drive mechanism 321 and the outer sleeve 322 are both mounted on a rotary table 313. The inner sleeve 323 is rotatably mounted inside the outer sleeve 322 and communicates with a through hole 3131. The probe 1 can pass through the through hole 3131 to penetrate into the inner sleeve 322. The bottom end of the outer sleeve 322 has two oppositely arranged sliding grooves 3221. The hinge 324 is provided in the sliding grooves 3221. The inner sleeve 323 and the hinge 324 are provided with mutually cooperating spiral structures 325. The second drive mechanism 321 is used to drive the inner sleeve 323 to rotate and drive all the hinges 324 to move radially along the probe 1 so that the hinges 324 abut against or move away from the probe 1.

[0063] Specifically, a semi-circular scraper 3241 is provided at one end of the hinge 324 near the probe 1. When all the hinges 324 are against the probe 1, the scraper 3241 can form a ring around the probe 1 to scrape off the attached material on the outside of the probe 1.

[0064] In this embodiment, the inner sleeve 322 is the guide unit 3a of the measuring rod 1, which can guide the falling position of the measuring rod 1.

[0065] In this embodiment, the ranging unit 6 is disposed on the top of the housing 8, and the ranging unit 6 is a laser rangefinder.

[0066] Through the above scheme, this embodiment allows for the measurement of the initial setting time of the cementitious material by carrying the measuring rod at different positions along the circumference of the material, and the measuring rod can be cleaned before each measurement operation. The specific measurement steps include:

[0067] 1. Place the cementitious material 5 to be tested below the housing 8 (i.e., the measuring rod 1);

[0068] 2. The second lifting component 3 drives the measuring rod 1 to rise, and the rotating component 31 drives the measuring rod 1 to rotate horizontally. When the magnet 12 at the top of the measuring rod 1 comes into contact with the electromagnet 21, the electromagnet 21 is energized and attracts the measuring rod 1.

[0069] 3. The second lifting assembly 3, when unloaded, drives the rotating assembly 31 and the cleaning assembly 32 to descend. During the descent of the cleaning assembly 32, the second drive mechanism 321 drives the inner sleeve 323 to rotate, so that all hinges 324 abut against the outer wall of the measuring rod 1, thereby performing a cleaning operation on the measuring rod during the descent. The second lifting assembly 3 stops moving when it reaches its lower limit.

[0070] 4. The first lifting component 2 drives the electromagnet 21 and the measuring rod 1 to descend. When the liquid level positioning rod 41 contacts the test mold 71 and triggers the position sensor 42, the electromagnet 21 is de-energized and releases the measuring rod 1.

[0071] 5. The measuring rod falls freely downwards and inserts into the cementitious material 5 to be tested below;

[0072] 6. After the depth of the test rod inserted into the cementitious material 5 to be tested is stable, the second lifting component 3 drives the rotary component 31 and the cleaning component 32 to rise.

[0073] 7. When the rotary table 313 comes into contact with the measuring rod 1, it will trigger the micro switch 3132 on the rotary table 313 to trigger the ranging unit 6 to detect the height of the measuring rod 1;

[0074] 8. The height of the measuring rod 1 obtained in step 7 can be used to calculate the depth of the measuring rod 1 inserted into the cementitious material 5 to be tested, thereby determining whether the cementitious material to be tested has reached the initial setting state. If it has not reached the initial setting state, steps 2 to 7 are repeated, and so on.

[0075] Example 2

[0076] This embodiment has a structure that is largely the same as that of Embodiment 1, with the improvement being the design of an automatic molding component.

[0077] In order to automatically inject the cementitious material 5 to be tested into the mold 71 for testing, an automatic mold assembly 7 is provided below the shell 8.

[0078] like Figure 9 and Figure 10As shown, the automatic mold assembly 7 includes a mold 71, a first moving mechanism 72, a second moving mechanism 73, and a feed pipe 74. The feed pipe 74 is connected to the feed pipe of the gel material to be tested. The mold 71 is positioned above the feed pipe 74. The mold 71 is used to hold the gel material 5 to be tested, and both the top and bottom of the mold 71 are open. The top of the mold 71 forms an opening 711 for inserting the test rod 1 into the gel material to be tested inside the mold 71. An input port is provided at the connection between the feed pipe 74 and the mold 71, which is the input end of the mold 71.

[0079] The first moving mechanism 72 has a valve plate 721 on its moving end, and the first moving mechanism 72 can drive the valve plate to close or open the input port; the second moving mechanism 73 has a scraper 731 on its moving end, and the second moving mechanism 73 can drive the scraper 731 to move along the upper surface of the mold 71.

[0080] In this embodiment, both the first moving mechanism 72 and the second moving mechanism 73 are lead screw guide rail mechanisms, and their structures are roughly the same as those of the first lifting assembly 2 and the second lifting assembly 3, so they will not be described in detail here.

[0081] The ranging unit 6 is also used to monitor the liquid level of the gelling material 5 to be tested within the test mold 71.

[0082] Preferably, the test mold 71 is a split test mold, which is formed by combining at least two mold bodies, so that the cementitious material inside the test mold 71 can be cleaned after the test is completed, so as to facilitate the replacement of different cementitious materials for testing.

[0083] The steps for injecting the cementitious material 5 to be tested into the mold 71 before testing include:

[0084] 11. The first moving mechanism 72 moves the valve plate 721 away from the inlet, so that the inlet is opened;

[0085] 12. The gelling material to be tested in the feed pipe 74 enters the mold 71 from the inlet. The liquid level of the gelling material to be tested is monitored by the measuring unit 6. When the liquid level reaches the top of the mold 71, the first moving mechanism 72 drives the valve plate 721 to close the inlet.

[0086] 13. The second moving mechanism 73 drives the scraper 731 to move along the upper surface of the mold 71 to scrape the excess cementitious material above the mold 71 into the recovery hopper 75, and then the initial setting test of the cementitious material to be tested can be carried out.

[0087] Example 3

[0088] This embodiment has a structure that is largely the same as that of Embodiment 1. This embodiment further defines the structure of the first drive mechanism 311 and the second drive mechanism 321.

[0089] In this embodiment, as Figure 5 The first drive mechanism 311 includes a servo motor, a drive wheel, and a driven wheel. The servo motor is mounted on the second mounting bracket 33, the drive wheel is located at the output end of the servo motor, and the driven wheel is mounted on the rotating shaft 312. The driven wheel and the drive wheel are connected by a synchronous belt. The servo motor drives the rotating shaft 312 to rotate via the drive wheel, the driven wheel, and the synchronous belt, thereby driving the rotating table 313 and the measuring rod 1 on the rotating table 313 to rotate. Specifically, the rotation axis of the rotating shaft 312 is the first axis.

[0090] In this embodiment, as Figure 7 As shown, the second drive mechanism 321 includes a servo motor, a drive gear, and a driven gear. The servo motor is mounted on the rotary table 313, the drive gear is mounted on the output end of the servo motor, and the driven gear is mounted on the inner sleeve 323. The drive gear and the driven gear mesh with each other. The servo motor is used to drive the inner sleeve 323 to rotate through the drive gear and the driven gear, thereby driving all the hinges 324 to move radially along the measuring rod 1 through the helical structure 325.
