Description

Technical Field

[0001] The utility model relates to the technical field of concrete precast member preparation, in particular to a pouring device for concrete precast member preparation. Background Art

[0002] The preparation of concrete precast members refers to the process of making concrete materials into members with a certain strength and predetermined dimensions through pre-design and prefabrication in a factory or prefabrication site.

[0003] During the production of precast members, the mixed concrete is usually poured into a specified mold. However, during the process of pouring the concrete into the mold, due to the fixing of the pipeline and the lack of a vibration mechanism at the bottom of the mold, the concrete is likely to accumulate at the same position during the pouring process, and it takes a long time of natural static placement to make the concrete evenly fill the mold, thus reducing the pouring efficiency of the precast members. Therefore, it is necessary to design a pouring device for concrete precast member preparation that can quickly and evenly fill the mold after the concrete is poured into the mold.

[0018] Please refer to Figures 1-5 , the present utility model provides a technical solution: a pouring device for the preparation of concrete precast members, including a casting box 1. A vibrating bottom plate 2 is movably clamped inside the casting box 1. An auxiliary vibration mechanism is arranged at the bottom of the vibrating bottom plate 2. A swinging feeding mechanism is arranged at the top of the casting box 1. A circular auxiliary plate 21 is fixedly installed near the rear side of the top of the vibrating bottom plate 2. A horizontal card slot 22 is opened on the rear inner wall of the casting box 1. A drive motor 23 is fixedly installed on the right side surface of the casting box 1. The left end of the drive motor 23 penetrates through the right inner wall of the horizontal card slot 22. A power threaded rod 24 is fixedly installed at the output end of the drive motor 23 extending into the horizontal card slot 22. A moving block 25 is threadedly connected to the outside of the power threaded rod 24. Swing assist plates 26 are fixedly installed at the front end of the moving block 25 and at positions on the left and right sides. A pressing plate 27 is fixedly installed at the bottom of the moving block 25. The bottom of the pressing plate 27 contacts the arc surface of the circular auxiliary plate 21.

[0019] Specifically, the auxiliary vibration mechanism includes a connecting cylinder 4. The connecting cylinder 4 is fixedly installed at the bottom of the vibration bottom plate 2. A vibration spring 41 is fixedly installed at the bottom of the connecting cylinder 4. The bottom end of the vibration spring 41 is fixedly installed on the inner bottom wall of the pouring box 1. A limiting round rod 42 is fixedly installed at the center position of the bottom end of the connecting cylinder 4. The vibration spring 41 is wound around the outside of the limiting round rod 42. The limiting round rod 42 is movably inserted into the bottom of the pouring box 1. The right inner wall of the pouring box 1 is movably hinged with a telescopic bottom cylinder 43. A circular clamping plate 44 is movably clamped in the inner cavity of the telescopic bottom cylinder 43. A telescopic connecting rod 45 is fixedly installed at the left end of the circular clamping plate 44. The telescopic connecting rod 45 is movably clamped with the left end of the telescopic bottom cylinder 43. The left end of the telescopic connecting rod 45 is movably hinged with the outside of the connecting cylinder 4. An auxiliary spring 46 is arranged in the inner cavity of the telescopic bottom cylinder 43. The auxiliary spring 46 is wound around the outside of the telescopic connecting rod 45.

[0020] In this embodiment, the cooperation of the auxiliary vibration mechanism causes the mold to vibrate, so that the concrete can quickly and evenly fill the mold.

[0021] Specifically, the feeding mechanism includes a spherical body slot 3. The spherical body slot 3 is opened at the top of the pouring box 1. A spherical body pipe 31 is movably clamped in the spherical body slot 3. Conveying pipes 32 are fixedly installed at both the upper and lower ends of the spherical body pipe 31.

[0022] In this embodiment, the cooperation of the feeding mechanism and structures such as the swinging assisting plate 26 enables the feeding mechanism to swing and convey concrete into the mold.

[0023] Specifically, the height difference of the arc surface of the circular auxiliary plate 21 is less than the distance from the vibration bottom plate 2 to the telescopic bottom cylinder 43.

[0024] In this embodiment, it is prevented that the circular auxiliary plate 21 touches the telescopic bottom cylinder 43 and causes damage to it when moving up and down.

[0025] Specifically, an arc limiting slot is opened at the top of the pouring box 1. The arc limiting slot is communicated with the spherical body slot 3. An arc limiting block is fixedly installed on the outside of the spherical body pipe 31. The arc limiting block is movably clamped with the arc limiting slot.

[0026] In this embodiment, the spherical body pipe 31 is rotated so that the spherical body pipe 31 can rotate in the horizontal plane.

[0027] In use, the top end of the conveying pipe 32 is connected to a concrete pipe. A specified mold is placed directly below the conveying pipe 32, and the concrete is injected into the mold through the conveying pipe 32. The driving motor 23 is started, and the driving motor 23 drives the power threaded rod 24 to rotate. During the rotation of the power threaded rod 24, under the restriction of the horizontal card slot 22, the moving block 25 is driven to move. The moving block 25 drives the swing assist plate 26 to move. When the swing assist plate 26 moves, it pushes the conveying pipe 32 to swing around the spherical card slot 3 as the center. During the swinging process of the conveying pipe 32, the concrete is injected into the mold, causing the concrete to spread and pour into the mold, preventing the concrete from accumulating at a certain place in the mold. At the same time, the moving block 25 drives the pressing plate 27 to move. When the pressing plate 27 moves from the arc bottom surface of the circular auxiliary plate 21 to the arc top surface, the pressing plate 27 presses the vibration bottom plate 2 to move downward through the circular auxiliary plate 21. The vibration bottom plate 2 drives the connecting cylinder 4 to move downward. The connecting cylinder 4 presses the vibration spring 41 downward to compress it. When the connecting cylinder 4 moves downward, it compresses the auxiliary spring 46 through the telescopic connecting rod 45 and the circular clamping plate 44. When the pressing plate 27 moves from the arc top surface of the circular auxiliary plate 21 to the arc bottom surface, the pressing plate 27 releases the pressing on the vibration bottom plate 2. At this time, the vibration spring 41 generates an upward thrust to push the vibration bottom plate 2 to move upward through the connecting cylinder 4. At the same time, the auxiliary spring 46 generates a thrust to drive the telescopic connecting rod 45 to move away from the connecting cylinder 4 through the circular clamping plate 44. The telescopic connecting rod 45 drives the vibration bottom plate 2 to move upward through the connecting cylinder 4. Through the cooperation between the vibration spring 41 and the auxiliary spring 46, the vibration bottom plate 2 is driven to move upward so that the arc surface of the circular auxiliary plate 21 always contacts the bottom of the pressing plate 27. During the up and down movement of the vibration bottom plate 2, the mold is driven to vibrate up and down, enabling the concrete in the mold to quickly and evenly fill the entire mold, thereby improving the pouring efficiency of the precast member.

[0028] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
