[0002] In the field of concrete pipe manufacturing, the molding quality of concrete pipes plays a key role in their performance and life in projects such as municipal drainage and underground pipeline laying. At present, traditional concrete pipe extrusion molding equipment generally has certain limitations.

[0003] On the one hand, most equipment lacks effective auxiliary means in the extrusion molding process and relies solely on pressure for molding, which makes it difficult for the interior of the concrete to be fully dense and prone to defects such as honeycombs and holes, resulting in insufficient pipeline strength. In subsequent use, it is easy to cause problems such as rupture and leakage, affecting the quality and service life of the project. On the other hand, existing equipment often cannot evenly distribute the concrete in the mold. The accumulation and uneven distribution of concrete will cause large differences in the strength of various parts of the pipeline, reducing the overall performance and stability of the pipeline.

[0026] The present invention will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0027] Embodiment 1: Please refer to Figure 1 and Figure 2 , a concrete pipe extrusion molding device, including an equipment base 1, a support column 2 fixedly connected to the equipment base 1, a top plate 3 fixedly connected to the top of the support column 2. Above the equipment base 1, a motor 4 is fixedly connected. The rotor of the motor 4 passes through the equipment base 1 and is connected to a drive shaft 5. A driving gear 6 is fixedly connected to the bottom of the drive shaft 5. Above the equipment base 1, a guide rod 7 is slidably connected. The top of the guide rod 7 is connected to a processing support plate 8. The processing support plate 8 is connected to the motor 4 through a vibration mechanism 9. In the middle of the processing bottom plate, a rotating inner plate 10 is rotatably connected. The rotating inner plate 10 is drivingly connected to the motor 4. On the top plate 3, a processing component 11 for pressure molding is further provided. On the side of the support column 2, a transmission component 12 for driving the processing of the processing component 11 is provided. The transmission component 12 is drivingly connected to the motor 4.

[0028] Use equipment such as a forklift to place the mold on the rotating inner plate 10. Turn on the motor 4. The rotation of the motor 4 drives the drive shaft 5 to rotate. The rotation of the drive shaft 5 drives the driving gear 6 to rotate. The rotation of the driving gear 6 drives the vibration mechanism 9, thereby realizing the vibration of the mold. At the same time, the rotating inner plate 10 rotates under the driving action of the motor 4, so that the concrete inside it can be more evenly dispersed to each position inside the mold. The processed pipe not only has high density but also uniform texture. In order to prevent the mold from falling on the rotating inner plate 10, corresponding clamps can be set according to the shape of the mold. The clamping fixture for the pipe mold belongs to the prior art for those skilled in the art and will not be elaborated here.

[0029] Please refer to Figure 2 and Figure 5, the vibration mechanism 9 includes a rotating vertical shaft 13. A driven gear 14 is fixedly connected to the bottom of the rotating vertical shaft 13. The driving gear 6 meshes with the driven gear 14. A rotating thread 15 is fixedly connected to the outside of the rotating vertical shaft 13. A driving bottom plate 16 is threadedly connected to the outside of the rotating thread 15. The bottoms of the guide rods 7 are fixedly connected to the driving bottom plate 16. A spring 17 is fixedly connected between the driving bottom plate 16 and the equipment base 1.

[0030] The rotation of the motor 4 drives the driven gear 14 to rotate through the driving gear 6. The rotation of the driven gear 14 can drive the rotation of the rotating vertical shaft 13. The rotating thread 15 on the outside of the rotating vertical shaft 13 will drive the driving bottom plate 16 to move to the topmost position. Since the rotating thread 15 disengages from the contact with the driving bottom plate 16 here, the rotating thread 15 and the internal thread of the driving bottom plate 16 will cooperate with each other, causing the driving bottom plate 16 to produce jerks up and down. The distance of the jerky movement is the distance of one thread pitch. During the jerky process, the guide rod 7 will drive the processing support plate 8 to produce jerks and synchronously transmit them to the mold through the rotating inner plate 10. When the motor 4 rotates in the reverse direction, first, the driving bottom plate 16 will move downward to the bottommost position and disengage from the contact with the rotating thread 15. The upper gear 18 will move downward synchronously as the position of the driving bottom plate 16 decreases. Then it will abut against the lower gear 19 and rotate synchronously with the lower gear 19 under the transmission of the transmission gear 20. At this time, there will be no sense of jerk. The motor 4 only drives the mold above the rotating inner plate 10 to rotate to achieve uniform dispersion of the concrete. After removing the mold, under the elastic force of the spring 17, the driving bottom plate 16 will cooperate with the rotating thread 15 to facilitate the motor 4 to drive the driving bottom plate 16 to the top position.

[0031] A upper gear 18 is fixedly connected to the bottom of the rotating inner plate 10. A lower gear 19 is fixedly connected to the top of the rotating vertical shaft 13 and is located below the upper gear 18. A transmission gear 20 is rotatably connected to the equipment base 1. The transmission gear 20 meshes with both the upper gear 18 and the lower gear 19. There are two transmission gears 20, which are symmetrically arranged between the upper gear 18 and the lower gear 19. The setting of the two transmission gears 20 makes the transmission process more stable.

[0032] Please refer to Figure 6 , the processing component 11 includes a number of pressure rings 21 with different diameters. Slide rods 22 are fixedly connected to the tops of the pressure rings 21. The slide rods 22 are slidably connected to the top plate 3. First magnets 23 are fixedly connected to the outside of the slide rods 22. The first magnets 23 are magnetically coupled with the top plate 3.

[0033] Embodiment 2: The following improvements are made to this embodiment on the basis of the previous embodiment: Please refer to Figure 3 、 Figure 4 and Figure 6, the transmission assembly 12 includes a pressure shaft 24 which is a threaded shaft. The bottom of the pressure shaft 24 is drivingly connected to the driving shaft 5. A driving base 25 is threadedly connected to the outside of the pressure shaft 24. The driving base 25 is slidably connected to the support column 2. An electric telescopic rod 26 is fixedly connected to the driving base 25. A pressure rod 27 is fixedly connected to the end of the electric telescopic rod 26. The pressure rod 27 is magnetically engaged with different pressure rings 21. During the telescopic process of the electric telescopic rod 26, the pressure rod 27 cooperates with different pressure rings 21.

[0034] A driven pulley 28 is fixedly connected to the bottom of the pressure shaft 24. A driving pulley 29 is fixedly connected to the outside of the driving shaft 5. The driving pulley 29 and the driven pulley 28 are synchronously driven by a synchronous belt 30.

[0035] The pressure rod 27 is in an L shape. A second magnet 31 is fixedly connected to the end of the pressure rod 27. There are two electric telescopic rods 26, and the two electric telescopic rods 26 drive the two pressure rods 27 to telescopically move synchronously at the same time.

[0036] While generating vibration, the rotating inner plate 10 also drives the mold to rotate synchronously. During the rotation of the motor 4, the driving base 25 moves up and down by controlling the rotation direction. During the up and down movement of the driving base 25, the pressure ring 21 is driven to move downward by the pressure rod 27. The pressure ring 21 enters between the inner and outer molds of the pipe, thereby compacting the concrete. On the contrary, the pressure rod 27 drives the pressure ring 21 to move upward, so that the pressure ring 21 is disengaged from the pressing operation. When the pressure ring 21 moves to the top, the first magnet 23 will be attracted to the top plate 3. When processing pipes with different diameters, by telescoping the electric telescopic rod 26, the pressure rod 27 can drive different pressure rings 21 to apply pressure, and the application range is wider.

[0037] Working principle: Use equipment such as forklifts to place the mold on the rotating inner plate 10. Turn on the motor 4. The rotation of the motor 4 drives the drive shaft 5 to rotate. The rotation of the drive shaft 5 drives the driving gear 6 to rotate. The rotation of the driving gear 6 drives the vibration mechanism 9, thereby realizing the vibration of the mold. At the same time, the rotating inner plate 10 rotates under the drive of the motor 4, so that the concrete inside it can be more evenly dispersed to various positions inside the mold. The processed pipe not only has high density but also uniform texture. In order to prevent the mold from falling on the rotating inner plate 10, corresponding fixtures can be set according to the shape of the mold. The clamping fixture for the pipe mold belongs to the prior art for those skilled in the art and will not be elaborated here. The rotation of the motor 4 drives the driven gear 14 to rotate through the driving gear 6. The rotation of the driven gear 14 can drive the rotating vertical shaft 13 to rotate. The rotating thread 15 on the outer side of the rotating vertical shaft 13 will drive the driving bottom plate 16 to move to the topmost position. Since the rotating thread 15 disengages from the contact with the driving bottom plate 16 here, the rotating thread 15 and the internal thread of the driving bottom plate 16 will cooperate with each other, causing the driving bottom plate 16 to have jerks up and down. The distance of the jerky movement is the distance of one thread pitch. During the jerky process, the guide rod 7 will drive the processing support plate 8 to have jerks and synchronously transmit them to the mold through the rotating inner plate 10. When the motor 4 rotates in the reverse direction, first, the driving bottom plate 16 will move downward to the bottommost position and disengage from the contact with the rotating thread 15. The upper gear 18 will move downward synchronously as the position of the driving bottom plate 16 decreases, and then abut against the lower gear 19 and rotate synchronously with the lower gear 19 under the transmission of the transmission gear 20. At this time, there will be no sense of jerk, and the motor 4 only drives the mold above the rotating inner plate 10 to rotate to achieve the uniform dispersion of the concrete. After removing the mold, under the elastic force of the spring 17, the driving bottom plate 16 will cooperate with the rotating thread 15 to facilitate the motor 4 to drive the driving bottom plate 16 to the top position. While generating vibration, the rotating inner plate 10 will also drive the mold to rotate synchronously. During the rotation of the motor 4, the driving base 25 moves up and down by controlling the rotation direction. During the up and down movement of the driving base 25, the pressure rod 27 drives the pressure ring 21 to move downward. The pressure ring 21 enters between the inner and outer molds of the pipe, thereby compacting the concrete. On the contrary, the pressure rod 27 will drive the pressure ring 21 to move upward, causing the pressure ring 21 to disengage from the pressurizing operation. When the pressure ring 21 moves to the top, the first magnet 23 will attract and combine with the top plate 3. When processing pipes with different diameters, by extending and retracting the electric telescopic rod 26, the pressure rod 27 can drive different pressure rings 21 to apply pressure, with a wider scope of application.
