Description

Technical Field

[0001] This invention relates to the field of grout production technology, specifically to a production system for concrete grout. Background Technology

[0002] Grouting material is a mixed additive composed of high-strength binder, expanding component, superplasticizing component and modified component. The quality of grouting material mainly depends on the proportion of components and the uniformity of mixing.

[0003] To improve the quality and production efficiency of grouting materials, the existing production system mainly includes a raw material mixing box, a grouting material packaging platform on one side of the raw material mixing box, an installation rod fixed on the top of the grouting material packaging platform near the raw material mixing box, a quantitative discharge box installed on the upper side of the installation rod, the quantitative discharge box located above the grouting material packaging platform, and a screw conveyor between the raw material mixing box and the top discharge box. The feed end of the screw conveyor is connected to the discharge port of the raw material mixing box, and the discharge end is inclined upward and connected to the feed port of the quantitative discharge box.

[0004] When preparing grout, the raw materials are added to the raw material mixing box for stirring and mixing. After the mixing is completed, the grout is transported to the quantitative discharge box by a screw conveyor. Then, the quantitative discharge box is used to add the grout to the material cylinder on the grout packaging platform to achieve packaging.

[0005] However, the existing grout production system does not have testing capabilities, especially for testing the expansion rate and compressive strength of the grout. This makes it unclear whether the produced grout has quality defects. Therefore, the existing production system needs to be improved. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a production system for concrete grouting materials, which solves the problem that existing grouting material production systems lack testing capabilities.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A production system for concrete grouting material includes a raw material mixing box, a grouting material packaging platform on one side of the raw material mixing box, an installation rod fixed on the top of the packaging platform near the raw material mixing box, a quantitative discharge box installed on the upper side of the installation rod, the quantitative discharge box being located above the grouting material packaging platform, and a screw conveyor between the raw material mixing box and the top discharge box, the inlet end of the screw conveyor being connected to the outlet of the raw material mixing box, and the outlet end being inclined upward and connected to the inlet of the quantitative discharge box.

[0009] The mounting rod is equipped with a rotatable connecting plate at its waist. The mounting rod is a threaded rod, and the connecting plate has a threaded hole at its center that allows it to be screwed onto the mounting rod. A dial indicator that can be adjusted up and down is provided on one side of the connecting plate. On both sides of the dial indicator, there is an elastic vibrating structure that can slide horizontally along the connecting plate. A rotatable testing box is also installed on the mounting rod. The upper opening of the testing box is covered with a glass plate, and the lower opening is sealed by a removable sealing plate. To facilitate the installation and removal of the sealing plate, the sealing plate is bolted to the lower opening of the testing box.

[0010] A hydraulic cylinder is provided on the other side of the connecting plate. A pressing plate is fixed to the lower end of the piston rod of the hydraulic cylinder. A detection plate is also fixed on the mounting rod. The detection plate is located directly below the pressing plate. The detection box can rotate to be between the pressing plate and the detection plate.

[0011] To enable the dial indicator to be adjusted up and down, an adjustment hole is provided on one side of the connecting plate, through which the dial indicator is inserted. A threaded post is screwed into the adjustment hole, and the lower end of the threaded post is fixed to the dial indicator.

[0012] In this invention, the elastic vibration structure specifically includes a long groove formed on a connecting plate, a sliding rod slidably installed in the long groove, with both the upper and lower ends of the sliding rod extending out of the long groove, a pressing plate fixed to the upper end of the sliding rod, and a vibrating ball fixed to the lower end of the sliding rod. A limiting ring is slidably installed on the connecting plate, the outer diameter of the limiting ring being larger than the width of the long groove. The upper and lower ends of the sliding rod extend out through the inner ring of the limiting ring, and a spring is provided between the limiting ring and the pressing plate, with the spring fitted onto the sliding rod.

[0013] To enable the rotation of the testing box, a lug with a threaded hole is fixed on the side of the testing box near the mounting rod. The lug is screwed onto the mounting rod through the threaded hole.

[0014] To ensure the strength of the testing plate during grout strength testing, inclined reinforcing ribs are provided between the mounting rod and the testing plate.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] After the grouting material is produced, a portion is added to the testing box until it overflows. The top is then smoothed out, and a glass plate is placed on the testing box. The dial gauge is adjusted until its probe touches the glass plate, which allows the expansion rate of the grouting material to be detected.

[0017] The present invention rotates the testing box until it is directly above the testing plate. After the grout solidifies, the sealing plate is opened, allowing the solidified grout to fall onto the testing plate. The hardness of the solidified grout is then tested by a hydraulic cylinder.

[0018] Finally, the most significant contribution of this invention is that it integrates the detection of grout expansion rate and hardness into one device. It has a simple structure and high practicality. When it is not necessary to test the grout, the connecting plate and the testing box can be rotated to a front-to-back arrangement without affecting the packaging of the grout.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0026] like Figure 1 As shown, the present invention provides a production system for concrete grouting material, including a raw material mixing box 1, a grouting material packaging platform 2 is provided on one side of the raw material mixing box 1, an installation rod 3 is fixed on the top of the grouting material packaging platform 2 near the raw material mixing box 1, a quantitative discharge box 4 is installed on the upper side of the installation rod 3, the quantitative discharge box 4 is located above the grouting material packaging platform 2, and a screw conveyor 5 is provided between the raw material mixing box 1 and the quantitative discharge box 4. The feed end of the screw conveyor 5 is connected to the discharge port of the raw material mixing box 1, and the discharge end is inclined upward and connected to the feed port of the quantitative discharge box 4.

[0027] When preparing grout, the raw materials are added to the raw material mixing box 1 and stirred. After the mixture is mixed, the grout is conveyed to the quantitative discharge box 4 by the screw conveyor 5. Then, the grout is added to the material cylinder on the grout packaging platform 2 through the quantitative discharge box 4 to achieve packaging. The above structure and principle are all existing technologies and will not be described in detail in this invention.

[0028] like Figure 2-4 As shown, a rotatable connecting plate 6 is also provided at the waist of the mounting rod 3. The mounting rod 3 is a threaded rod, and a threaded hole is opened at the center of the connecting plate 6 so that it can be screwed onto the mounting rod 3. A dial indicator 7 that can be adjusted up and down is provided on one side of the connecting plate 6. The principle of the dial indicator 7 is existing technology and will not be described in detail in this invention. In order to realize the up and down adjustment of the dial indicator 7, an adjustment hole that runs through the top and bottom is opened on one side of the connecting plate 6. A threaded column 14 is screwed into the adjustment hole, and the lower end of the threaded column 14 is fixed on the dial indicator 7. An elastic vibration structure that can slide horizontally along the connecting plate 6 is provided on both sides of the dial indicator 7. After the grouting material is produced, a portion is added to the test box 8 until it overflows. The top is smoothed, and then the glass plate 9 is placed on the test box 8. The dial indicator 7 is adjusted until its probe touches the glass plate 9, and the expansion rate of the grouting material can be detected.

[0029] like Figure 5 As shown, in this invention, the elastic vibration structure specifically includes a long groove 15 formed on the connecting plate 6. A slide rod 21 is slidably installed in the long groove 15. The upper and lower ends of the slide rod 21 extend out of the long groove 15. A pressing plate 16 is fixed to the upper end of the slide rod 21, and a vibration ball 17 is fixed to the lower end of the slide rod 21. A limiting ring 18 is slidably installed on the connecting plate 6. The outer diameter of the limiting ring 18 is larger than the groove width of the long groove 15. The upper and lower ends of the slide rod 21 extend out through the inner ring of the limiting ring 18. A spring 19 is provided between the limiting ring 18 and the pressing plate 16. The spring 19 is fitted onto the slide rod 21.

[0030] During the grout expansion rate test, rotate the test chamber 8 to directly below the quantitative discharge box 4, remove the glass plate 9, and inject grout into the test chamber 8 through the quantitative discharge box 4. When the grout is 50mm inside the test chamber 8, press down the pressing plate 16. At this time, the spring 19 is compressed, and the slide rod 21 drives the vibrating ball 17 to move down into the grout in the test chamber 8. Release the pressing plate 16, and the spring 19 will drive the vibrating ball 17 back to its original position. Repeat pressing down the pressing plate 16 several times to vibrate the grout and expel air bubbles. Continue to inject grout into the test chamber 8. When the grout reaches 90mm, it is vibrated using an elastic vibrating structure. The slide bar 21 can slide horizontally along the long groove 15 to change the vibration position, resulting in a larger vibration range and better effect. Continue injecting grout until it flows out from both sides of the test box 8. Smooth the grout at the top opening of the test box 8, then cover the top opening of the test box 8 with the glass plate 9. Rotate the threaded column 14 to move the dial indicator 7 down until the probe of the dial indicator 7 touches the glass plate 9. Record the expansion value from 3h to 24h, calculate the difference between the two values, and then calculate the collision rate.

[0031] like Figure 2-3As shown, a rotatable testing box 8 is also installed on the mounting rod 3. To enable the rotation of the testing box 8, a lug with a threaded hole is fixed on the side of the testing box 8 near the mounting rod 3. The lug is screwed onto the mounting rod 3 through the threaded hole. The upper opening of the testing box 8 is covered by a glass plate 9, and the lower opening is sealed by a removable sealing plate 10. To enable the installation and removal of the sealing plate 10, the sealing plate 10 is bolted to the lower opening of the testing box 8. A hydraulic cylinder 11 is provided on the other side of the connecting plate 6. The lower end of the piston rod of the hydraulic cylinder 11 is fixed with... The extrusion plate 12 has a test plate 13 fixed on the mounting rod 3. The test plate 13 is located directly below the extrusion plate 12. To ensure the strength of the test plate 13 during the grout strength test, an inclined reinforcing rib 20 is provided between the mounting rod 3 and the test plate 13. The test box 8 can be rotated between the extrusion plate 12 and the test plate 13. Rotate the test box 8 until it is directly above the test plate 13. After the grout solidifies, the sealing plate 10 is opened, allowing the solidified grout to fall onto the test plate 13. The hardness of the solidified grout is then tested by the hydraulic cylinder 11.

[0032] When testing the hardness of the grout, rotate the testing box 8 180 degrees to be directly above the testing plate 13 and leave it stationary for 24 hours. Then, remove the sealing plate 10 from the testing box 8. Note that to facilitate the removal of the cured grout from the testing box 8, apply a layer of oil to the inner wall of the testing box 8 before injecting the grout. Push the cured grout out of the testing box 8 and place it on the testing plate 13. Then rotate the testing box 8 to the side, and then start the hydraulic cylinder 11 to move the extrusion plate 12 downward, pressurizing the cured grout until it breaks. The hardness of the grout can be obtained from the parameters on the hydraulic cylinder 11, and then the compressive strength can be calculated.

[0033] Finally, the most significant contribution of this invention is that it integrates the detection of grout expansion rate and hardness into one device. It has a simple structure and high practicality. When it is not necessary to detect the grout, the connecting plate 6 and the detection box 8 can be rotated to a front-to-back arrangement without affecting the packaging of the grout.
