In use, the vibrating rod is inserted into the concrete to vibrate and remove air bubbles. However, this method has the following problems: for some precast components with high strength requirements, the air removal requirements are high, and relying solely on vibration is insufficient to completely remove air bubbles, making it inconvenient to use and lacking in practicality and reliability. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a concrete internal air bubble removal device that promotes the discharge of air bubbles through a dual method of vibration and vacuuming, resulting in better air bubble discharge, ease of use, and high practicality and reliability.

[0004] This utility model discloses a concrete internal air bubble removal device, comprising a base plate, a support plate, and a vibrator. The vibrator is equipped with a connecting line and a vibrating rod, and the vibrator is connected to the vibrating rod via the connecting line. It also includes a vacuum mechanism, a lifting mechanism, and a moving mechanism. The vibrating rod is mounted on the moving mechanism, which is used to move the vibrating rod. The support plate is mounted on the lifting mechanism, which is used to raise and lower the support plate. The vacuum mechanism has a vacuuming function and is located above the support plate. During the production of precast concrete components, the mold is placed on the upper part of the support plate, and then concrete is poured into the mold. The moving mechanism then inserts the vibrating rod into the mold, vibrating the concrete to remove air bubbles. Simultaneously, the vacuuming mechanism creates a vacuum above the mold, further promoting the removal of air bubbles from the concrete. This device promotes the removal of air bubbles from the concrete through a dual method of vibration and vacuuming, resulting in better air bubble removal, ease of use, and high practicality and reliability.

[0005] Preferably, the vacuum mechanism includes a hoisting frame, a housing, and a vacuum pump. The housing is fixedly mounted on the hoisting frame, and a cavity is provided inside the housing. The lower end of the housing is open, and the housing is located above the support plate. The downward projection of the housing is located in the support plate. The vacuum pump is mounted on the housing, and the input end of the vacuum pump is located inside the cavity of the housing. The hoisting frame is fixedly hoisted on the workshop support. After the mold is poured, the support plate is raised by the lifting mechanism so that the upper end of the support plate contacts the lower end of the housing, so that the mold is located in the sealed space formed by the support plate and the housing. Then, the vacuum pump is turned on to evacuate the housing and promote the discharge of air bubbles in the concrete in the mold.

[0006] Preferably, the lifting mechanism includes a hydraulic cylinder A, a push rod, a fixed column, and a sliding column. The hydraulic cylinder A is fixedly installed on the upper end of the base plate, and the output end of the hydraulic cylinder A is provided with a push rod. The fixed column is fixedly installed on the base plate, and the lower part of the sliding column is slidably installed on the sliding column. The support plate is fixedly installed on the upper end of the sliding column and the push rod. When it is necessary to adjust the height of the support plate, the hydraulic cylinder A is opened, and the hydraulic cylinder A adjusts the height of the support plate by pushing the push rod. This facilitates the adjustment of the support plate height.

[0007] Preferably, the moving mechanism includes a hydraulic cylinder B, a moving rod, a sliding rod, an electric cross slide, a sliding block, and a flexible rubber rod. The hydraulic cylinder B is fixedly installed at the upper end of the housing. The output end of the hydraulic cylinder B is provided with a moving rod.

The vibrating rod 5 is mounted on the moving mechanism, which is used to move the vibrating rod 5. The support plate 2 is mounted on the lifting mechanism, which is used to raise and lower the support plate 2. The vacuum mechanism has a vacuuming function and is located above the support plate 2. When producing precast concrete components, a mold 19 is placed on the upper end of the support plate 2, and then concrete is poured into the mold 19. The moving mechanism then inserts the vibrating rod 5 into the mold 19, vibrating the concrete to remove air bubbles. Simultaneously, the vacuuming mechanism creates a vacuum above the mold 19, further promoting the removal of air bubbles from the concrete within the mold 19. This device promotes the removal of air bubbles from the concrete through a dual method of vibration and vacuuming, resulting in better air bubble removal, ease of use, and high practicality and reliability.

[0020] like Figure 1 and Figure 5 The vacuum mechanism includes a lifting frame 6, a housing 7, and a vacuum pump 8. The housing 7 is fixedly installed on the lifting frame 6 and has a cavity inside. The lower end of the housing 7 is open. The housing 7 is located above the support plate 2, and the downward projection of the housing 7 is located in the support plate 2. The vacuum pump 8 is installed on the housing 7, and the input end of the vacuum pump 8 is located inside the cavity of the housing 7. The lifting frame 6 is fixedly suspended on the support frame in the workshop. After the mold 19 is poured, the support plate 2 is raised by the lifting mechanism so that the upper end of the support plate 2 contacts the lower end of the housing 7, so that the mold 19 is located in the sealed space formed by the support plate 2 and the housing 7. Then, the vacuum pump 8 is turned on to evacuate the housing 7 and promote the discharge of air bubbles in the concrete in the mold 19.

[0021] like Figure 4 The lifting mechanism includes a hydraulic cylinder A9, a push rod 10, a fixed column 11, and a sliding column 12. The hydraulic cylinder A9 is fixedly installed on the upper end of the base plate 1, and the output end of the hydraulic cylinder A9 is provided with the push rod 10. The fixed column 11 is fixedly installed on the base plate 1, and the lower part of the sliding column 12 is slidably installed on the sliding column 12. The support plate 2 is fixedly installed on the upper end of the sliding column 12 and the push rod 10. When it is necessary to adjust the height of the support plate 2, the hydraulic cylinder A9 is opened, and the hydraulic cylinder A9 adjusts the height of the support plate 2 through the push rod 10. This facilitates the adjustment of the height of the support plate 2.

[0022] like Figure 1 and Figure 3The moving mechanism includes a hydraulic cylinder B13, a moving rod 14, a sliding rod 15, an electric cross slide 16, a sliding block 17, and a flexible rubber rod 18.

After the upper end of the support plate 2 contacts the lower end of the box body 7, the hydraulic cylinder B13 is opened. The hydraulic cylinder B13 moves the electric cross slide 16, which in turn moves the sliding block 17 and the flexible rubber rod 18 downward via the moving rod 14. This causes the vibrator 5 to descend into the concrete in the mold 19. Then, the vibrator 5 is opened to vibrate and vent the concrete in the mold 19. At the same time, the electric cross slide 16 can be opened, which moves the sliding block 17 horizontally. This causes the flexible rubber rod 18 to move the vibrator 5 horizontally, allowing the vibrator 5 to vibrate and vent the concrete in various parts of the mold 19. This facilitates the vibration of the concrete.
