Technical Field
[0001] The utility model relates to the technical field of concrete structure plates, in particular to a bubble removing device for the production of concrete structure plates. Background Technique
[0002] A concrete structure plate is a plate-shaped object made of concrete materials and is a basic structure or component in building construction and various engineering structures. It is commonly used as a roof, floor, platform, wall, foundation, floor, road surface, water tank, etc., with a very wide range of applications. However, during the pouring process of the concrete structure plate, it is generally poured into a mold arranged in a grid. The surface of a set of molds is provided with a plurality of mold grooves, and there will be certain air bubbles in the concrete slurry after it is filled into the mold grooves. When there are more air bubbles, it will affect the strength of the concrete structure plate itself, and further affect the strength of the platform, wall, etc. built by the concrete structure plate, having a certain potential safety hazard. Therefore, technical personnel in this field have provided a bubble removing device for the production of concrete structure plates to solve the problems raised in the above background technique. Content of the Utility Model
[0003] The purpose of the utility model is to provide a bubble removing device for the production of concrete structure plates to solve the problems raised in the above background technique.
[0004] To achieve the above purpose, the utility model provides the following technical solution:
[0005] A bubble removing device for the production of concrete structure plates includes a column. The bottom end of the column is fixedly connected with a fixed foot, the top end of the column is fixedly connected with a top plate, the lower surface of the top plate is fixedly connected with cylinders in a matrix shape. A vertical rod is slidably connected inside each cylinder, and the lower end of each vertical rod extends to the lower side of the cylinder. A bubble removing component is arranged inside the top plate.
[0006] As a further scheme of the utility model: The bubble removing component includes a rotating disk. An inner cavity is opened inside the top plate, the rotating disk is located inside the inner cavity, a motor is fixedly connected to the upper surface of the top plate, the driving end of the motor extends to the inside of the inner cavity and is fixedly connected to the center of the upper surface of the rotating disk. A protrusion is fixedly connected to the lower surface of the rotating disk. The top end of each vertical rod extends to the inside of the inner cavity, and a ball head is arranged at the top end of each vertical rod. The uppermost end of the active range of the ball head is located above the lower surface of the protrusion.
[0007] As a further scheme of the utility model: A retaining ring is fixedly connected to the surface of the vertical rod. The retaining ring is located inside the cylinder. A spring is sleeved on the surface of the vertical rod. The upper end of the spring abuts against the lower surface of the retaining ring, and the lower end of the spring abuts against the inner wall of the cylinder.
[0008] As a further solution of the utility model: an exhaust thin rod is fixedly connected to the bottom end of the vertical rod.
[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0010] By designing the cylinders in a matrix, a vertical rod is arranged in each cylinder. For a matrix-type mold, the lower end of each vertical rod can extend into the concrete slurry in the mold groove. The protrusion and the ball head are in indirect contact. When the ball head contacts the protrusion, the spring can be compressed, so that the lower end of the vertical rod and the exhaust thin rod move downward in the concrete slurry. When the ball head and the protrusion are disengaged, the spring resets, so that the lower end of the vertical rod and the exhaust thin rod move upward in the concrete slurry. Thus, the lower end of the vertical rod and the exhaust thin rod move up and down repeatedly in the concrete slurry, causing the concrete slurry to vibrate, so that the bubbles inside it are discharged. After the concrete slurry is completely solidified, a bubble-free concrete structure board can be finally obtained, improving the strength of the concrete structure board. Description of the Drawings

[0016] Please refer to Figures 1 to 4 , in the embodiment of the utility model, a bubble removal device for the production of concrete structure boards includes a column 1. A fixed foot 2 is fixedly connected to the bottom end of the column 1, a top plate 3 is fixedly connected to the top end of the column 1, cylinders 5 are fixedly connected to the lower surface of the top plate 3 in a matrix shape, a vertical rod 6 is slidably connected to the inside of each cylinder 5, and the lower end of each vertical rod 6 extends to the lower side of the cylinder 5. An air bubble removal assembly is arranged inside the top plate 3.
[0017] Preferably, the bubble removing assembly includes a rotating disk 9. An inner cavity 8 is formed inside the top plate 3. The rotating disk 9 is located inside the inner cavity 8. A motor 4 is fixedly connected to the upper surface of the top plate 3. The driving end of the motor 4 extends into the inner cavity 8 and is fixedly connected to the center of the upper surface of the rotating disk 9. A protrusion 10 is fixedly connected to the lower surface of the rotating disk 9. The top end of each vertical rod 6 extends into the inner cavity 8, and a ball head 11 is provided at the top end of each vertical rod 6. The uppermost end of the moving range of the ball head 11 is located above the lower surface of the protrusion 10.
[0018] Preferably, a retaining ring 12 is fixedly connected to the surface of the vertical rod 6. The retaining ring 12 is located inside the cylinder 5. A spring 13 is sleeved on the surface of the vertical rod 6. The upper end of the spring 13 abuts against the lower surface of the retaining ring 12, and the lower end of the spring 13 abuts against the inner wall of the cylinder 5, which is used to control the upward movement of the vertical rod 6. Cooperating with the protrusion 10 to press down the ball head 11 makes the vertical rod 6 move downward, and finally realizes the up and down vibration of the vertical rod 6, which is convenient for discharging the bubbles in the concrete slurry.
[0019] Preferably, an exhaust thin rod 7 is fixedly connected to the bottom end of the vertical rod 6. The use of the exhaust thin rod 7 can increase the contact part with the concrete slurry, which is convenient for the concrete slurry to exhaust more thoroughly.
[0020] The working principle of the present utility model is as follows: When removing bubbles inside the concrete structure slab, it is necessary to first fill the concrete slurry into the matrix-shaped molds. A certain amount of concrete slurry is filled in each mold groove. Then, the mold filled with the concrete slurry is moved to the lower side of the top plate 3, and the lower end of each vertical rod 6 extends into the concrete slurry in each mold groove. Then, the motor 4 is turned on to make the rotating disk 9 rotate. By using the indirect contact between the protrusion 10 and the ball head 11, when the ball head 11 contacts the protrusion 10, the spring 13 can be compressed, so that the lower end of the vertical rod 6 and the exhaust thin rod 7 move downward in the concrete slurry. When the ball head 11 disengages from the protrusion 10, the spring 13 resets, so that the lower end of the vertical rod 6 and the exhaust thin rod 7 move upward in the concrete slurry. Thus, the lower end of the vertical rod 6 and the exhaust thin rod 7 move up and down in the concrete slurry, generating vibration in the concrete slurry, so that the internal bubbles are discharged. After the concrete slurry is completely solidified, a bubble-free concrete structure slab is finally obtained.
[0021] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
