Description
Technical Field
[0001] The invention belongs to the technical field related to building construction, and in particular relates to an automatic electric cement grouting machine. Background Art
[0002] In the field of construction, filling and reinforcing building gaps and filling and repairing building cracks are crucial links. Traditional cement grouting methods have many problems.
[0003] On the one hand, traditional cement grouting equipment usually has a single function, and it is difficult to achieve efficient pressurization function and output stable high-pressure cement, resulting in poor filling effect on building gaps and cracks. The pressure control is not accurate enough and it is difficult to meet the specific requirements for cement pressure in different construction scenarios.
[0004] On the other hand, traditional equipment often requires a lot of energy when starting, and the startup process is difficult and slow. The motor faces great resistance during the startup phase, which not only wastes energy but also may affect the service life of the equipment.
[0005] In addition, it is difficult for traditional cement grouting equipment to maintain a stable pressure output during the grouting process. When the pressure fluctuates, it will affect the filling quality and easily lead to loose filling. Moreover, after the equipment stops running, the cement is easy to flow back, and the pressure in the pipeline cannot be effectively maintained, which is not conducive to the subsequent pressure maintenance operation.

[0018] Compared with the prior art, the present invention provides an automatic electric cement grouting machine having the following
[0019] Beneficial effects:
[0020] 1. Through the sequential arrangement of the pressurized pipe, the primary booster pipe and the secondary booster pipe, with the inner diameter decreasing in sequence, multiple pressurization of cement is achieved, ensuring that high-pressure cement is output from the front end of the secondary booster pipe, efficiently filling and reinforcing the gaps in the building or filling and repairing the cracks in the building. At the same time, the electric control box can accurately control the start and stop and speed of the grouting motor to achieve precise control of the grouting process.
[0021] 2. When the grouting motor is started, the front end of the transformer push plate fits with the rear end of the pressure push plate under the action of the return spring. At this time, the density of the spiral plate pushed inside the pressure tube is relatively small, and the motor shaft is subject to little resistance, so it can be easily and quickly started and accelerated, with less starting energy consumption and more energy saving.
[0022] 3. During the speed-up process of the grouting motor, when the reaction force of cement on the pressure push plate and the transformer push plate increases, the transformer push plate slides backward outside the motor shaft, and the two rotate separately, increasing the density of the pushing spiral plate inside the pressure pipe, thereby increasing the internal pressure of the cement, improving the grouting efficiency and effect, and realizing adaptive pressurization.
[0023] 4. The rear end of the secondary boost pipe is elastically connected to the limit ring at the front end of the primary boost pipe through an extrusion slide rod and an extrusion spring. During the secondary boost process, the overall internal space of the primary boost pipe and the secondary boost pipe can be increased, and the overall internal space can be squeezed when the pressure is reduced to adjust the pressure, thereby ensuring that the cement pressure output from the front end of the secondary boost pipe remains stable and improving the grouting quality.
[0024] 5. When the grouting motor stops running, the plugging head is blocked to the rear end of the plugging ring under the action of the plugging spring to prevent cement backflow and maintain the cement pressure inside the primary booster pipe and the secondary booster pipe. At the same time, the secondary booster pipe and the expansion slide pipe continue to squeeze the internal space under the action of the extrusion spring, providing high-pressure cement for the pressure-maintaining process without the need for additional power, reducing energy consumption and saving energy.

The cement grouting machine can be used to fill and reinforce building gaps, and can also be used to fill and repair building cracks , cement is introduced into the pressurized pipe 4 through the feed hopper 5, and the grouting motor 3 is turned on through the electrical control box 2. The grouting motor 3 drives the pressurized push plate 9 and the transformer push plate 10 to rotate through the motor shaft 8. The pressurized push plate 9 and the transformer push plate 10 push the cement forward by rotating, and generate pressure inside the cement. After the cement enters the primary boosting pipe 6 and the secondary boosting pipe 7 from the pressurized pipe 4, since the inner diameters of the primary boosting pipe 6 and the secondary boosting pipe 7 are reduced successively, the cement can be pressurized multiple times inside the primary boosting pipe 6 and the secondary boosting pipe 7 successively, thereby outputting high-pressure cement from the front end of the secondary boosting pipe 7. The high-pressure cement can be sprayed into the building gap or building crack through the pipe and grouting head connected to the front end of the secondary boosting pipe 7, thereby automatically filling and reinforcing the building gap or automatically filling and repairing the building crack. Among them, the electrical control box 2 can control the start and stop and speed of the grouting motor 3.
[0036] Preferably, the spiral outer wall at the front end of the transformer push plate 10 fits with the spiral outer wall at the rear end of the pressurizing push plate 9, and the spiral outer diameter of the transformer push plate 10 is larger than the spiral outer diameter of the pressurizing push plate 9. The transformer push plate 10 is fixedly connected to a limiting sleeve 11 at one end near the motor shaft 8. The transformer push plate 10 and the limiting sleeve 11 are sleeved on the outside of the motor shaft 8 and are slidably connected to the motor shaft 8, and the transformer push plate 10 and the limiting sleeve 11 are rotatably connected to the inside of the pressurizing pipe 4. The front end of the transformer push plate 10 is fixedly connected with a plurality of connecting rods 12, and the front ends of the plurality of connecting rods 12 are fixedly connected with a connecting frame 13, and the connecting frame 13 is located on the front side of the motor shaft 8.

The rear end of the telescopic rod 14 is provided with a return spring 16, and is elastically connected to the inside of the limit telescopic hole 15 through the return spring 16. When the grouting motor 3 starts to start, since the transformer push plate 10 and the limit sleeve 11 are connected to the connecting frame 13 and the limit telescopic rod 14 through multiple connecting rods 12, and the limit telescopic rod 14 is elastically connected to the inside of the limit telescopic hole 15 opened at the front end of the motor shaft 8 through the return spring 16, the spiral outer wall at the front end of the transformer push plate 10 fits with the spiral outer wall at the rear end of the pressure push plate 9 under the action of the return spring 16, so that the pressure push plate 9 and the transformer push plate 10 become a whole to push the cement. At this time, the pushing spiral plate density inside the pressure pipe 4 is relatively small, and the reaction force of the cement on the pressure push plate 9 and the transformer push plate 10 is relatively small, so that the resistance of the motor shaft 8 is relatively small, so that the grouting motor 3 can be easily and quickly started and accelerated, and the energy of starting and accelerating is smaller, which is more energy-saving.
[0037] Preferably, during the speed-up process of the grouting motor 3, the reaction force of the cement on the pressure push plate 9 and the transformer push plate 10 increases. Since the pressure push plate 9 is fixedly connected to the outside of the motor shaft 8, the transformer push plate 10 and the limit sleeve 11 are slidably connected to the outside of the motor shaft 8, and the spiral outer diameter of the transformer push plate 10 is larger than the spiral outer diameter of the pressure push plate 9, the transformer push plate 10 and the limit sleeve 11 will slide backward on the outside of the motor shaft 8 under the reaction force of the cement, and through the square limit telescopic rod 14 and the square limit telescopic hole 15 limits the position with the motor shaft 8, ensures that the transformer push plate 10 can always rotate with the motor shaft 8, at this time, the pressure push plate 9 and the transformer push plate 10 rotate separately, so that the pressure push plate 9 and the transformer push plate 10 can push the cement separately, thereby increasing the density of the pushing spiral plate inside the pressure tube 4, thereby increasing the pressure inside the cement, improving the grouting efficiency and grouting effect, and after the grouting motor 3 stops running, the transformer push plate 10 can return to its original position again under the action of the return spring 16 and fit with the pressure push plate 9.
[0038] Preferably, a limiting ring 17 is fixedly connected to the outer side of the front end of the primary boost pipe 6, and a plurality of extrusion slide bars 18 are passed through the interior of the limiting ring 17 from front to back. The plurality of extrusion slide bars 18 are fixedly connected to the outer side of the rear end of the secondary boost pipe 7 and are slidably connected to the limiting ring 17. An extrusion spring 19 is sleeved on the outer side of the extrusion slide bar 18, and the extrusion spring 19 is elastically connected to the limiting ring 17, and the extrusion spring 19 is located at the rear end of the limiting ring 17. An expansion slide tube 20 is fixedly connected to the rear end of the secondary boost pipe 7, and the expansion slide tube 20 is slidably connected to the interior of the front end of the secondary boost pipe 7. A plugging ring 21 is fixedly connected inside, a plugging head 22 is clamped inside the rear end of the plugging ring 21, a limit slide rod 23 is fixedly connected at the center of the rear end of the plugging head 22, a limit frame 24 is sleeved on the rear side of the limit slide rod 23, and is slidably connected with the limit frame 24, the limit frame 24 is fixedly connected to the inner wall of the primary booster pipe 6, a plugging spring 25 is sleeved on the outside of the limit slide rod 23, and the plugging spring 25 is located between the plugging head 22 and the limit frame 24, the plugging head 22 and the limit slide rod 23 are elastically connected between the plugging ring 21 and the limit frame 24 through the limit frame 24, and when cement enters When it reaches the inside of the primary boosting pipe 6 and the secondary boosting pipe 7, the cement pushes the plugging head 22 out from the rear end of the plugging ring 21, and enters the primary boosting pipe 6 from the gap between the plugging ring 21 and the plugging head 22 for primary boosting, and then enters the secondary boosting pipe 7 through the expansion slide 20 for secondary boosting. In the process of secondary boosting, since the secondary boosting pipe 7 and the expansion slide 20 are elastically connected to the limit ring 17 through multiple extrusion slide rods 18 and multiple extrusion springs 19, the secondary boosting pipe 7 will drive the expansion slide 20 to slide forward inside the primary boosting pipe 6 , and increase the overall internal space of the primary boost tube 6 and the secondary boost tube 7. At this time, the secondary boost tube 7 and the expansion slide tube 20 will squeeze the overall internal space of the primary boost tube 6 and the secondary boost tube 7 under the action of multiple squeezing slide bars 18 and multiple squeezing springs 19. When the cement pressure inside the primary boost tube 6 and the secondary boost tube 7 is reduced, the secondary boost tube 7 and the expansion slide tube 20 can adjust the pressure by pressurizing the overall internal space of the primary boost tube 6 and the secondary boost tube 7, thereby ensuring that the cement pressure output from the front end of the secondary boost tube 7 remains stable, thereby improving the grouting quality.
[0039] Preferably, when the grouting motor 3 stops running, do not pull out the grouting head, let the grouting head continue to be inserted in the building gap or building crack for a period of time to maintain pressure, to ensure that the gap or crack is completely filled, at this time, the cement inside the pressure tube 4 no longer enters the primary boost tube 6, and the sealing head 22 is sealed to the rear end of the sealing ring 21 again under the action of the sealing spring 25, so that the cement inside the primary boost tube 6 and the secondary boost tube 7 will not flow back into the pressure tube 4, and the pressure of the cement inside the primary boost tube 6 and the secondary boost tube 7 is maintained. At the same time, the secondary boost tube 7 and the expansion slide tube 20 squeeze the entire internal space of the primary boost tube 6 and the secondary boost tube 7 under the action of multiple squeezing slide rods 18 and multiple squeezing springs 19, so that the secondary boost tube 7 can continue to output high-pressure cement with stable pressure, and continue to provide high-pressure cement for the pressure maintaining process, without the need for additional power, reducing energy consumption, and being more energy-saving.
