Description

Technical Field

[0001] This invention relates to the field of cement grouting machines, specifically an intelligent dual-liquid cement grouting machine with a constant speed control motor. Background Technology

[0002] Grouting machines are professional construction machines used for chemical grouting and sealing of cracks, expansion joints, construction joints, and structural joints in various buildings and underground concrete structures, as well as for structural reinforcement. They use high-pressure injection to stop water leakage. The high-pressure grouting sealant is a low-viscosity, single-component synthetic high-molecular polyurethane material in the form of a slurry. It has the characteristic of reacting with water to produce a cross-linking reaction and foaming to form a multi-element network closed elastomer.

[0003] Chinese Patent CN213742460U discloses a manual cement grouting machine for concrete joint repair, specifically relating to the technical field of cement grouting machines. The machine includes a grouting machine body with a mounting base fixedly connected to its bottom. A base is located below the mounting base, and the mounting base and base are connected via a lifting assembly. The lifting assembly includes two support plates mounted on top of the base, fixedly connected to the base. The two support plates are connected by a first connecting plate. A first lead screw is located at the bottom of the mounting base, connected to the mounting base via a first bearing. The first lead screw passes through the first connecting plate, and the connection between the first lead screw and the first connecting plate is a threaded connection. This invention facilitates adjustment of the height of the cement grouting machine body. Through the cooperation of a support plate and a second toothed plate, the position of the first toothed plate is limited, preventing the mounting base from wobbling up and down, thus increasing stability.

[0004] Existing cement grouting machines may only be able to discharge cement or other liquids separately during use, and cannot mix different liquids inside the grouting machine, which leads to the problem of needing to mix them after discharge.

[0005] Therefore, to address the above problems, an intelligent dual-liquid cement grouting machine with a constant speed control motor is proposed. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1

[0030] Please see Figures 1 to 7As shown, an intelligent dual-liquid cement grouting machine with a constant-speed control motor includes a cement grouting machine body 1. A hinge 2 is fixedly connected to the outer wall of the cement grouting machine body 1, and a grouting machine opening / closing cover 3 is fixedly connected to one side of the hinge 2. An opening / closing pin assembly 4 is fixedly connected to the other side of the grouting machine opening / closing cover 3. A cement extraction inlet 5 is provided inside the cement grouting machine body 1, and a cement input pipe 6 is connected inside the cement extraction inlet 5. A hydraulic motor 7 is installed on one side of the cement input pipe 6, and a motor speed limiter 8 is electrically connected to the other side of the hydraulic motor 7. A controller 9 is installed on one side of the body 1, and a lifting base 10 is fixedly connected to the top of the cement grouting machine body 1. A lifting arm 11 is slidably connected inside the lifting base 10, and a lifting motor 12 is electrically connected to one side of the lifting base 10. A lifting gripper 13 is fixedly connected to one side of the lifting arm 11, and a locking pull rod 14 is engaged inside the lifting gripper 13. A pull rod return spring 15 is tightly fitted to the top of the locking pull rod 14, and a pull rod locking pin 16 is slidably connected to the bottom of the locking pull rod 14. A return piece 17 is integrally provided on the outer wall of the pull rod locking pin 16. Furthermore, a locking pin and a reset spring 18 are tightly fitted to one side of the reset plate 17, and a locking slot 19 is engaged with one end of the locking pin 16 of the pull rod. A double liquid separator plate 20 is slidably connected to the outer wall of the locking pull rod 14, and a separator plate handle 21 is integrally provided on the top of the double liquid separator plate 20. A grouting discharge pipe 24 is connected to the other side of the cement grouting machine body 1, and a spherical flow limiting block 25 is fixedly connected inside the grouting discharge pipe 24. A flow limiting rotating bead 26 is rotatably connected inside the spherical flow limiting block 25, and a flow limiting rotating bead 26 is fixedly connected to the top of the flow limiting rotating bead 26. The handle 27 and the opening / closing pin assembly 4 include an opening / closing pin connecting block 401, an opening / closing pin button retaining strip 402, an opening / closing pin return spring 403, an opening / closing pin insertion block 404, and an opening / closing pin engaging groove 405. The opening / closing pin connecting block 401 is internally engaged with the opening / closing pin button retaining strip 402, and one side of the opening / closing pin button retaining strip 402 is tightly fitted with the opening / closing pin return spring 403. One side of the opening / closing pin connecting block 401 is tightly fitted with the opening / closing pin insertion block 404, and the opening / closing pin engaging groove 405 is internally provided with an opening / closing pin engaging groove 405.

[0031] Please see Figure 1 and Figure 7As shown, the opening / closing pin button retainer 402 forms an elastic structure with the opening / closing pin reset spring 403 and the opening / closing pin connecting block 401. The opening / closing pin connecting block 401 forms an engaging structure with the opening / closing pin insertion block 404 through the opening / closing pin button retainer 402, the opening / closing pin engaging groove 405, and the opening / closing pin insertion block 404. By pressing the opening / closing pin button retainer 402, the opening / closing pin button retainer 402 slides into the opening / closing pin connecting block 401, pressing the opening / closing pin reset spring 403 and losing the engaging connection with the opening / closing pin engaging groove 405. This allows the opening / closing pin button retainer 402 to be pulled out from the opening / closing pin insertion block 404, so that the grouting machine opening / closing cover 3 can be opened to view the internal condition of the cement grouting machine body 1 for subsequent cleaning or internal maintenance.

[0032] Please see Figure 2 and Figure 6 As shown, the cement grouting machine body 1 is connected to the grouting discharge pipe 24 through the outlet spherical flow limiting block 25, the flow limiting rotating bead 26, and the flow limiting rotating bead 26 is connected to the grouting discharge pipe 24 through the outlet spherical flow limiting block 25. When the mixed liquid flows out through the grouting discharge pipe 24, when it passes through the outlet spherical flow limiting block 25, the flow limiting rotating bead 26 can be rotated by the flow limiting rotating handle 27 to adjust different flow rates or stop the discharge.

[0033] Please see Figures 1 to 4 As shown, the locking lever 14 forms a detachable structure with the lifting gripper 13 and the lifting arm 11, and the lifting gripper 13 forms a lifting structure with the lifting arm 11 and the lifting base 10. The lifting arm 11 rises from the lifting base 10, and the lifting gripper 13 on one side of the lifting arm 11 can grip or release. When the lifting gripper 13 grips the locking lever 14, the lifting arm 11 drives the lifting gripper 13 to rise, and the lifting gripper 13 will drive the locking lever 14 to rise together, further driving the double liquid separator plate 20 to slide upward.

[0034] Please see Figures 4 to 5 As shown, the locking lever 14 forms an elastic structure with the double liquid separator plate 20 through the lever return spring 15, and the locking lever 14 and the double liquid separator plate 20 form a sliding structure. The locking lever 14 first slides upward from the inside of the double liquid separator plate 20 until it engages the separator plate handle 21. The locking lever 14 slides upward and presses the lever return spring 15. The locking lever 14 controls the bottom lever locking pin 16, and the elastic force of the lever return spring 15 increases the downward pressure of the locking lever 14.

[0035] Please see Figures 4 to 5As shown, the pull rod engaging pin 16 forms an elastic structure with the double liquid separator plate 20 through the reset piece 17, the engaging pin reset spring 18, and the double liquid separator plate 20. The double liquid separator plate 20 forms an engaging structure with the cement grouting machine body 1 through the pull rod engaging pin 16. When the engaging pull rod 14 is released, the pull rod reset spring 15 loses pressure and restores its elasticity. It slides downward under its own weight until it engages with the inclined surface of the pull rod engaging pin 16. The inclined surfaces of the engaging pull rod 14 and the engaging pin 16 slide against each other. The engaging pull rod 14 pushes the pull rod engaging pin 16 outward until it enters the engaging slot 19. The slot of the double liquid separator plate 20 is embedded in the inner wall of the cement grouting machine body 1, thereby preventing the liquids from mixing together when separated.

[0036] Working Principle: First, after moving the cement grouting machine body 1 to a suitable position, connect different liquid inlet pipes to the cement extraction inlet 5 according to requirements. The hydraulic motor 7 then uses piston movement to extract the liquid into the cement grouting machine body 1. A motor speed limiter 8 next to the hydraulic motor 7 controls the motor speed, thereby changing the extraction volume. The hydraulic motor 7, motor speed limiter 8, lifting motor 12, and mixing motor 22 are all connected to the controller 9 via wiring, facilitating intelligent control and manual operation. The controller 9 can operate individual or all motors individually. After cement or other liquids are extracted into the cement grouting machine body 1, if it is necessary to mix the two liquids... When in use, the lifting motor 12 can be started by the controller 9, causing the lifting arm 11 to rise from the lifting base 10. The lifting gripper 13 on one side of the lifting arm 11 can be gripped or released. When the lifting gripper 13 grips the locking lever 14, the lifting arm 11 drives the lifting gripper 13 to rise, and the lifting gripper 13 will drive the locking lever 14 to rise together. The locking lever 14 first slides upward from inside the double liquid separator 20 until it engages the separator handle 21. The locking lever 14 slides upward and presses the lever return spring 15. Then the lever locking pin 16 loses the engagement from the locking lever 14, and is thus pushed by the locking pin return spring 18 to the return plate 17, which drives the lever to move upward. The lever locking pin 16 retracts inward until it loses engagement with the locking slot 19. This causes the lifting gripper 13 to slide the locking lever 14, the separator handle 21, and the dual-liquid separator 20 upwards until the lifting motor 12 stops manually or reaches a predetermined height. The controller 9 then automatically stops the lifting motor 12. When the lifting gripper 13 releases the locking lever 14, the dual-liquid separator 20 can be manually lifted upwards, thus controlling it to engage with different locking slots 19. The controller 9 then starts the stirring motor 22, which drives the stirring rod 23 to agitate the liquids, accelerating the mixing of the two liquids. When discharging separately, the locking lever 14 is released, the lever return spring 15 loses pressure and restores its elasticity, and slides downward under its own weight until it engages with the inclined surface of the locking pin 16. The locking lever 14 and the inclined surface of the locking pin 16 slide against each other, and the locking lever 14 pushes the locking pin 16 outward until it enters the locking slot 19. The groove of the locking double liquid separator 20 is embedded in the inner wall of the cement grouting machine body 1, thereby preventing the liquids from mixing together when separated. The liquid flows outward through the grouting discharge pipe 24. When passing through the spherical flow limiting block 25 at the discharge outlet, the flow limiting ball 26 can be rotated by the flow limiting rotating handle 27 to adjust different flow rates or stop the discharge.

[0037] Next, when the grouting machine is finished using or needs maintenance or cleaning, press the opening and closing pin button clip 402 to slide the opening and closing pin button clip 402 into the opening and closing pin connecting block 401, press the opening and closing pin return spring 403, and lose the engagement connection with the opening and closing pin engagement groove 405. This will pull the opening and closing pin button clip 402 out of the opening and closing pin insertion block 404, causing the grouting machine opening and closing cover 3 to lose the engagement connection with the cement grouting machine body 1. Then, the grouting machine opening and closing cover 3 can be opened by rotating along the hinge 2, so that the internal condition of the cement grouting machine body 1 can be viewed and subsequent cleaning or internal maintenance can be carried out.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
