Description

Technical Field

[0001] The present application relates to the technical field of grouting machines, and in particular to a grouting quantity control mechanism of a plugging grouting machine. Background Art

[0002] In current civil engineering, tunnel construction, and underground pipeline maintenance, leak-proof grouting technology is a crucial repair method, widely used to address structural cracks, leaks, and other problems. However, traditional leak-proof grouting machines present several challenges. For one thing, the grouting machine's material tank is typically a fixed structure, and the slurry inside tends to settle and clump after prolonged periods of static storage, seriously affecting the quality and effectiveness of the grouting. This settling and agglomeration can lead to blockage in the grouting pipeline and uneven grouting, significantly compromising the leak-proofing effect.

[0003] On the other hand, traditional grouting machines often only have one grouting container during leak plugging operations. When the grout in that container runs out, the machine needs to be stopped for refilling. This results in long waiting times and frequent downtime, significantly reducing work efficiency. In large-scale leak plugging projects, this inefficient working method can significantly extend construction time, increase project costs, and even affect project progress and quality.

[0004] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application. Therefore, it may contain information that does not constitute the prior art known to ordinary technicians in this field. Utility Model Content

[0005] In order to solve the problem that the material box of the grouting machine is usually a fixed structure, the slurry inside is easy to settle and agglomerate after standing for a long time, which will seriously affect the quality and effect of grouting; and the traditional grouting machine often has only one grouting container. When the slurry in the container is used up, it needs to be stopped for refilling, which leads to a long waiting time, frequent shutdowns, and greatly reduced work efficiency, the present application provides a grouting amount control mechanism for a leak-proof grouting machine.

[0006] The present application provides a grouting quantity control mechanism for a plugging grouting machine that adopts the following technical solution:

[0007] A grouting quantity control mechanism for a plugging grouting machine comprises a base, a frame fixed on the base, a mounting frame installed in the frame, a movable grouting machine material box installed inside the mounting frame, a discharge pipe fixed at the center of the bottom of the grouting machine material box, a material distribution mechanism provided on one side of the discharge pipe, the material distribution mechanism comprising a cylinder located at the bottom of the grouting machine material box, a connecting frame fixed to the output end of the cylinder, and connecting arms staggeredly distributed on both sides of the connecting frame, a conduit installed inside the connecting arm, and a grouting measuring cylinder connected to the output end of the conduit.

[0008] Preferably, a supporting leg is welded to the bottom end of the base, a swing cylinder is installed on the outer wall of the mounting frame, and the output end of the swing cylinder extends into the mounting frame and is connected to gear 1 for transmission.

[0009] Preferably, rotating shafts are fixed at both ends of the outer wall of the grouting machine material box, and gear 2 is fixed to the outer wall of one of the rotating shafts, and gear 2 is rotatably connected to the inner wall of the mounting frame, and gear 1 and gear 2 are meshed.

[0010] Preferably, a servo motor is fixed to one side of the bottom of the grouting machine material box, the output end of the servo motor is connected to the cylinder, and support arms are fixed on both sides of the bottom end of the connecting frame.

[0011] Preferably, the interior of the two support arms is movably connected with a connecting rod, and one end of the connecting rod extends to the outside of the support arm and is fixed with a hoop block.

[0012] Preferably, the outer wall of the grouting graduated cylinder is provided with a scale bar, and a grouting pipe is connected to the center of the bottom of the grouting graduated cylinder.

[0013] In summary, this application has the following beneficial technical effects:

[0014] The present application can effectively promote the mixing of the internal slurry by setting the grouting machine material box to be movable, prevent the slurry from settling and agglomerating due to long-term static state, and improve the quality and effect of grouting. Through the combination of the servo motor, the cylinder and the connecting frame, during the plugging work, a specific grouting measuring cylinder is driven close to the bottom of the discharge pipe, and the cylinder contracts to drive the connecting frame to move upward, pushing the catheter into the inside of the discharge pipe, realizing precise connection and establishment of the grouting channel. Two grouting measuring cylinders are set. When one grouting measuring cylinder finishes grouting, the other grouting measuring cylinder can quickly take over for grouting. This alternating material replacement method realizes continuous operation, reduces waiting time and downtime, and improves work efficiency. Especially in large-scale plugging projects, it can significantly shorten construction time and improve project progress. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following is combined with Figure 1-3 This application is described in further detail.

[0020] The embodiment of the present application discloses a grouting quantity control mechanism of a plugging grouting machine. Figure 1-Figure 2 , including a base 1, a supporting leg 2 is welded to the bottom end of the base 1, a frame 3 is fixed on the base 1, a mounting frame 4 is installed in the frame 3, a movable grouting machine box 5 is installed inside the mounting frame 4, and a swing cylinder 6 is installed on the outer wall of the mounting frame 4. The output end of the swing cylinder 6 extends into the mounting frame 4 and is connected to a gear 1 7 for transmission. A rotating shaft 9 is fixed at both ends of the outer wall of the grouting machine box 5, and the rotating shaft 9 is rotatably connected to the inner wall of the mounting frame 4, and a gear 2 8 is fixed to the outer wall of one of the rotating shafts 9. By driving the gear 1 7 to rotate and engage with the gear 2 8 through the swing cylinder 6, the rotating shaft 9 can be driven to drive the grouting machine box 5 to swing in the mounting frame 4, which can help mix the slurry inside the grouting machine box 5 and avoid precipitation and agglomeration.

[0021] In the present application, a discharge pipe 11 is fixed at the center of the bottom of the grouting machine material box 5, and a material distribution mechanism is provided on one side of the discharge pipe 11. The material distribution mechanism includes a cylinder 15 located at the bottom of the grouting machine material box 5, a connecting frame 16 fixed to the output end of the cylinder 15, and connecting arms 17 staggered on both sides of the connecting frame 16, and a conduit 18 is installed inside the connecting arm 17. The output end of the conduit 18 is connected to the grouting measuring cylinder 10. A servo motor 14 is fixed to one side of the bottom of the grouting machine material box 5. The output end of the servo motor 14 is connected to the cylinder 15, so that the entire material distribution mechanism can be driven to rotate, so as to drive the conduit 18 to be close to the bottom of the discharge pipe 11 for grouting.

[0022] Combine Figure 3 As shown, support arms 19 are fixed on both sides of the bottom end of the connecting frame 16, and the interior of the two support arms 19 is movably connected with a connecting rod 20. One end of the connecting rod 20 extends to the outside of the support arm 19 and is fixed with a hoop block 21. A spring is connected between the support arm 19 and the inner wall of the connecting rod 20 to facilitate the contraction of the hoop block 21, which can adapt to the positioning of catheters 18 of different sizes.

[0023] In the present application, a scale bar 12 is provided on the outer wall of the grouting measuring cylinder 10, and the grouting amount inside the grouting measuring cylinder 10 can be observed through the scale bar 12, which is convenient for quantitative control to avoid too much or too little slurry, and a grouting pipe 13 is connected to the center of the bottom of the grouting measuring cylinder 10, and electromagnetic valves are installed outside the grouting pipe 13 and the discharge pipe 11. When the solenoid valve is opened, the internal slurry can be discharged through the grouting pipe 13 to perform leak plugging work.

[0024] The implementation principle of the grouting amount control mechanism of the plugging grouting machine of the present application is as follows: when in use, the swing cylinder 6 drives the gear 1 7 to rotate and mesh with the gear 2 8, which can drive the rotating shaft 9 to drive the grouting machine material box 5 to swing left and right in the mounting frame 4, which can promote the mixing of the internal slurry and avoid the slurry precipitation and agglomeration caused by long-term static state. The rotation parameters of the servo motor 14 are pre-adjusted. When plugging the leak, the servo motor 14 drives the connecting frame 16 to rotate, so that one side of the connecting arm 17 is close to the bottom of the discharge pipe 11. At this time, the cylinder 15 contracts to drive the entire connecting frame 16 to move upward, and then push The conduit 18 is stuck into the inside of the discharge pipe 11, and the solenoid valve is opened at this time. The slurry inside the grouting machine box 5 is discharged into the inside of the grouting measuring cylinder 10 through the conduit 18. The internal grouting capacity can be observed through the scale bar 12, which is convenient for quantitative control. When the grouting of the grouting measuring cylinder 10 is completed, the servo motor 14 is driven to rotate in the opposite direction. At this time, another grouting measuring cylinder 10 can be driven close to the bottom of the conduit 18, and the above work is repeated until the grouting measuring cylinder 10 is filled with slurry. Through the above operation, the material can be replenished alternately, which greatly improves the efficiency of grouting. When plugging leaks, the external working pipeline can be connected through the grouting pipe 13 to carry out plugging work.
