The purpose of vibration is to remove air bubbles and excess water from the concrete, allowing the concrete to fully fill every corner of the mold, improving the density and uniformity of the concrete, thereby ensuring the strength, durability, and appearance quality of the precast components.

[0003] Currently, the vibrating devices used in the production of precast concrete components often have rollers installed at the bottom for easy movement. For example, patent application number 202222261111.0 discloses a cement precast component mold vibrator. However, the vibrator is prone to movement during the vibration process, and the vibration range of these vibrating devices cannot be changed, making them difficult to apply to molds of different sizes. Summary of the Invention

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1: Please refer to Figures 1 to 6 :

[0027] This utility model proposes a vibration device for precast molds, comprising: a main support frame 1; a roller support frame 2 slidably mounted on both the front and rear sides of the main support frame 1, and a roller 3 mounted on the left and right sides of the bottom of the roller support frame 2. The main support frame 1 is used to support other parts of the device structure, and the roller support frame 2 is used to support the roller 3. In use, the main support frame 1 can be moved to the top of the precast mold to be vibrated by supporting the roller 3; an electric cylinder 4 is fixed at the middle position of both the front and rear sides of the main support frame 1, and the bottom end of the electric cylinder 4 is fixedly connected to the middle position of the top of the roller support frame 2. When the electric cylinder 4 extends or retracts, it can adjust the height of the roller support frame 2; the inner side of the top of the main support frame 1 Seven guide rods 5 are welded at equal intervals. An upper support plate 6 is slidably installed on the outside of the seven guide rods 5. The guide rods 5 are used to slide and support the upper support plate 6, which in turn supports the vibratory motor 7 and the vibratory rod 8. Two vibratory motors 7 are installed on the top left and right sides of the upper support plate 6, and the vibratory rod 8 is also installed at the bottom of the upper support plate 6 by nuts. When in use, the vibratory motors 7 can be turned on. When the vibratory motors 7 are working, they will drive the upper support plate 6 to sway back and forth under the support of the guide rods 5. At the same time, the springs on the outside of the guide rods 5 can also play a buffering role to prevent the upper support plate 6 from directly colliding with the main support frame 1 and being damaged. Therefore, the upper support plate 6 can drive the vibratory rod 8 to vibrate at high speed to compact the concrete in the precast mold.

[0028] In this embodiment, as Figure 6 As shown, the upper support plate 6 is also provided with six rows of thirty through holes in a ring array. These six rows of through holes are staggered with the front and rear through holes on the upper support plate 6. The through holes on the upper support plate 6 are used to install and fix the vibrator 8, and the vibrator 8 will not conflict with the guide rod 5 when it is installed.

[0029] In this embodiment, as Figures 1-5 As shown, the main support frame 1 has a vertical rectangular opening on both the front, back, left and right sides. The roller support frame 2 is an inverted U-shaped frame, and the vertical rods on both sides of the roller support frame 2 can slide up and down in the rectangular opening on the main support frame 1 and fit tightly against the inner wall of the rectangular opening, thereby ensuring that the roller support frame 2 can slide up and down stably.

[0030] In this embodiment, as Figures 1-5 As shown, the left and right sides of the main support frame 1 are open structures. After the vibrator 8 is installed, its bottom end will be located 2cm above the bottom surface of the main support frame 1. The open left and right sides of the main support frame 1 make it easy to push it above the mold. Moreover, when in use, the bottom end of the vibrator 8 will also be inserted into the mold to ensure that the concrete in the mold can be vibrated.

[0031] In this embodiment, as Figures 1-5 As shown, when the roller support frame 2 slides down to the bottom, the roller 3 will be below the bottom surface of the main support frame 1. When the roller support frame 2 slides up to the top, the roller 3 will be above the bottom surface of the main support frame 1. Therefore, when the roller support frame 2 slides down to the bottom, the roller 3 can support and push the main support frame 1 to move above the precast mold that needs to be vibrated. When the roller support frame 2 slides up to the top, the bottom surface of the main support frame 1 will contact the ground, thereby fixing the position of the device.

[0032] In this embodiment, as Figures 1-6 As shown, the upper support plate 6 has seven through holes with an inner diameter equal to the outer diameter of the guide rod 5. The front and rear ends of the guide rod 5 are also equipped with springs. When the vibration motor 7 is working, it will drive the upper support plate 6 to sway back and forth under the support of the guide rod 5. At the same time, the springs on the outside of the guide rod 5 can also play a buffering role to prevent the upper support plate 6 from directly colliding with the main support frame 1 and being damaged. Therefore, the upper support plate 6 can drive the vibrator 8 to vibrate at high speed to compact the concrete in the precast mold.

[0033] Example 2, based on Example 1, such as Figures 1-6 As shown, each vibrator 8 has a threaded rod at its top end with an outer diameter equal to the inner diameter of the through holes on the upper support plate 6. The threaded rod is connected to the main body of the vibrator 8 via a circular plate. When in use, the vibrator 8 can be installed according to the size of the mold to be vibrated. During installation, simply insert the threaded rod at the top end of the vibrator 8 into the through holes on the upper support plate 6 from bottom to top, and then screw a nut on the outer side of the top end of the threaded rod. This will firmly fix the vibrator 8 to the bottom of the upper support plate 6. The circular plate below the threaded rod can also serve as a limiting device during installation.

[0034] The working principle of this embodiment is as follows: During the manufacturing of this device, both the electric cylinder 4 and the vibration motor 7 can be connected to the controller and a power plug can be reserved. When this device is needed to vibrate precast concrete components, the device can be connected to the power supply first. Then, the two electric cylinders 4 can be controlled to extend synchronously to push the roller support frame 2 downward to the bottom. At this time, the roller 3 will contact the ground. Then, the vibrator 8 can be installed according to the size of the mold to be vibrated. During installation, simply insert the threaded rod at the top of the vibrator 8 into the through hole on the upper support plate 6 from bottom to top, and then screw a nut on the outer side of the top of the threaded rod. This will firmly fix the vibrator 8 to the bottom of the upper support plate 6. Moreover, the number of vibrators 8 installed can be adjusted to adapt to different applications. Different sized molds are used, and then the main support frame 1 can be moved to the top of the precast mold to be vibrated by the support of the rollers 3. At this time, the two electric cylinders 4 can be controlled to retract synchronously, driving the roller support frame 2 to slide upward to the top. At this time, the bottom surface of the main support frame 1 will contact the ground, thereby fixing the position of the device. At the same time, the bottom end of the vibrator 8 will be inserted into the mold. Then the vibration motor 7 can be turned on. When the vibration motor 7 is working, it will drive the upper support plate 6 to sway back and forth under the support of the guide rod 5. At the same time, the spring on the outside of the guide rod 5 can also play a buffering role to prevent the upper support plate 6 from directly colliding with the main support frame 1 and being damaged. Therefore, the upper support plate 6 can drive the vibrator 8 to vibrate at high speed to vibrate the concrete in the precast mold.
