Description
Technical Field
[0001] The present application relates to the technical field of engineering instruments, and in particular to a grouting material fluidity measuring instrument. Background Art
[0002] The grouting material fluidity tester is a device used to measure the fluidity of grouting materials. The specific working process is to pour the evenly stirred slurry into the inverted cone to a certain loading volume, then open the bottom opening to allow the slurry to flow out freely. The time for the slurry to flow out completely is recorded. This time is the fluidity of the grouting material.
[0003] Existing methods for timing the flow of grouting materials are typically manual. A person presses the start button when the bottom of the guide cone opens, and presses the stop button when all the grouting fluid has flowed out. This is subject to significant human influence, which can easily lead to large timing errors. The initial flowability of some grouting materials currently on the market falls within the technical parameter limits required by regulations. Timing results directly affect the material's acceptance, and large errors in timing can easily lead to less convincing judgments about the material. Utility Model Content

DETAILED DESCRIPTION
[0036] The following is combined with Figure 1-6 This application is described in further detail.
[0037] The present application embodiment discloses a grouting material fluidity measuring instrument. Figure 1 The grouting material fluidity measuring instrument includes an inverted cone 1, a connecting frame 2, a sealing member 3 and a timer 4.
[0038] Reference Figure 2 and Figure 3 The bottom of the inverted cone 1 is provided with a slurry outlet 5 that is connected to the interior of the inverted cone 1 for discharging materials. The connecting frame 2 is fixedly connected to the inverted cone 1, and a start button 6 and an end button 7 are movably connected to the connecting frame 2. The closing member 3 is rotatably connected to the connecting frame 2 and is used to open and close the slurry outlet 5. The timer 4 is mounted on the connecting frame 2 and is electrically connected to the start button 6 and the end button 7 via a micro switch. When the start button 6 is pressed, the closing member 3 rotates to open the slurry outlet 5, and the timer 4 starts timing; when the end button 7 is pressed, the timer 4 ends timing.
[0039] Reference Figure 2 and Figure 3, wherein the connecting frame 2 includes a connecting rod 201 and a connecting seat 202. One end of the connecting rod 201 is fixedly connected to the outer wall of the inverted cone 1, and the other end of the connecting rod 201 extends horizontally away from the inverted cone 1. The connecting seat 202 is fixed to the end of the connecting rod 201 away from the inverted cone 1. One end of the closing member 3 has a rotating shaft 12 rotatably connected to the connecting seat 202. The axis of the rotating shaft 12 extends horizontally and is perpendicular to the connecting rod 201. The connection between the closing member 3 and the rotating shaft 12 is located on the lower side of the rotating shaft 12, and a clearance cavity 19 for making way for the closing member 3 is opened at the lower part of the connecting seat 202, so that the closing member 3 extends out of the connecting seat 202 and can rotate with the rotating shaft 12.
[0040] The timer 4 is mounted on the connecting base 202, and the start button 6 and the end button 7 slide in the connecting base 202 along the axial direction parallel to the rotating shaft 12, and the start button 6 and the end button 7 are respectively located on opposite sides of the connecting base 202, and the rotating shaft 12 is located between the start button 6 and the end button 7.
[0041] Microswitches (not shown) that cooperate with the start button 6 and the end button 7 are located on opposite sides of the start button 6 and the end button 7, respectively. In their initial positions, one end of each of the start and end buttons 6 and 7 extends outside the connector 202. When the start button 6 is pressed and moved into the connector 202, the corresponding microswitch actuates, sending a start signal to the timer 4, causing it to begin timing. When the end button 7 is pressed and moved into the connector 202, the corresponding microswitch actuates, sending a stop signal to the timer 4, causing it to stop timing.
[0042] Reference Figure 4 and Figure 5 A linkage member 8 is fixed to the side of the start button 6 facing the rotating shaft 12. The linkage member 8 is in the shape of a convex column. The end of the linkage member 8 away from the start button 6 extends to the rotating shaft 12 and presses into the rotating shaft 12. A sliding groove 13 for the linkage member 8 to press into and slide is provided on the outer peripheral wall of the rotating shaft 12. The sliding groove 13 extends obliquely along the circumference of the rotating shaft 12 toward the direction away from the start button 6.
[0043] When the start button 6 is in the initial position, the linkage member 8 abuts against the end of the chute 13 near the start button 6, and the closure member 3 closes the slurry outlet 5. Pressing the start button 6 drives the linkage member 8 to move in the chute 13. The cooperation between the linkage member 8 and the chute 13 drives the rotation shaft 12 to rotate, thereby driving the closure member 3 to rotate downward to open the slurry outlet 5. The timer 4 starts timing at the same time as the slurry outlet 5 is opened. After observing that the slurry is discharged, press the end button 7 to stop the timer 4.
[0044] To reset the start button 6 and the end button 7, the closure member 3 is rotated again to close the pulp outlet 5. This allows the start button 6 to return to its initial position through the linkage between the rotating shaft 12 and the linkage member 8. A reset member 16 is mounted in the connection base 202 to reset the end button 7. This reset member 16 can be a spring, a spring, or other elastic component, preferably a spring in this embodiment. After pressing the end button 7, the elastic force of the spring drives the end button 7 toward the outside of the connection base 202 to its initial position.
[0045] Reference Figure 4 Furthermore, the upper surface of the start button 6 has a first travel portion 14 protruding from the start button 6. The first travel portion 14 is block-shaped. The connecting seat 202 defines a first travel groove 15 for the first travel portion 14 to slide along the movement direction of the start button 6. The first travel groove 15 does not pass through the end of the connecting seat 202, so that the first travel groove 15 limits the movement of the start button 6. Similarly, the upper surface of the end button 7 has a second travel portion 17 protruding from the end button 7. The connecting seat 202 defines a second travel groove 18 for the second travel portion 17 to slide along the movement direction of the end button 7. The second travel groove 18 does not pass through the end of the connecting seat 202, so that the second travel groove 18 limits the movement of the end button 7.
[0046] Reference Figure 2 and Figure 6 Furthermore, the closing member 3 includes a closing seat 31 and a force transmission frame 32. The force transmission frame 32 is in the shape of a connecting rod 201 composed of a plurality of rods fixedly connected in sequence. One end of the force transmission frame 32 is connected to the rotating shaft 12, and the end of the force transmission frame 32 away from the rotating shaft 12 is fixedly connected to the closing seat 31. The closing seat 31 includes a mounting seat 311 and a rubber pad 312. The mounting seat 311 is block-shaped, and a mounting groove 10 for accommodating the rubber pad 312 is provided on the surface of the mounting seat 311 on the side away from the force transmission frame 32. The rubber pad 312 is made of rubber with a certain elastic force. The upper surface of the rubber pad 312 is flush with the surface of the mounting seat 311 and is a closing surface 9, and the area of the closing surface 9 is larger than the area of the slurry outlet 5.
[0047] An attraction seat 11 is fixed to the outer wall of the bottom of the inverted cone 1. A magnet is embedded in the attraction seat 11, and the mounting seat 311 is made of a metal material that can be magnetically attracted. When the start button 6 is in the initial state, the closing surface 9 of the rubber pad 312 abuts against the bottom of the inverted cone 1 to close the slurry outlet 5. At the same time, the surface of the mounting seat 311 is opposite to the attraction seat 11, so that the attraction seat 11 gives the mounting seat 311 an upward rotation suction force, so that the rubber pad 312 is pressed against the inverted cone 1 and deformed, so that the rubber pad 312 can close the slurry outlet 5. At the same time, the magnetic attraction force of the attraction seat 11 on the mounting seat 311 is greater than the gravity of the slurry in the inverted cone 1, so that when no additional pulling force is applied to the force transmission frame 32 and the closing seat 31, the slurry in the inverted cone 1 is not easy to flush the closing seat 31 open.
[0048] Reference Figure 6 Furthermore, the mounting seat 311 has a protrusion 20 fixed on the inner wall of the mounting groove 10, and the rubber pad 312 has a groove 21 on the outer wall. When the rubber pad 312 is inserted into the mounting seat 311, it deforms when passing over the protrusion 20. When the rubber pad 312 moves to the point where the protrusion 20 faces the groove 21, the rubber pad 312 deforms and returns to its original position, and the protrusion 20 presses into the groove 21, thereby limiting the position of the rubber pad 312 and improving its stability in the mounting seat 311. When the rubber pad 312 needs to be replaced, the rubber pad 312 is squeezed to disengage the protrusion 20 from the groove 21, allowing it to be quickly removed.
[0049] The operating principle of the grouting material fluidity tester according to the embodiment of the present application is as follows: first, place the inverted cone 1 on a stand with the tester's slurry outlet 5 facing downward, and then pour slurry into the inverted cone 1. Then, press the start button 6 to rotate the rotating shaft 12 via the linkage 8, causing the timer 4 to start timing. Simultaneously, the closing seat 31 moves away from the slurry outlet 5, opening the slurry outlet 5. After the slurry has drained out, press the end button 7 to end the timer 4.
[0050] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
