A vibratory exhaust device for concrete processing

Abstract

A concrete processing vibration exhaust device is characterized by comprising an upper plate, a lower plate, and a vibration transmission assembly. The upper plate is disposed above the lower plate, and the vibration transmission assembly is disposed between the upper and lower plates. The vibration transmission assembly is used to vibrate the upper and lower plates. The upper and lower plates are used to fix the cement products. The uncured concrete in the first and second placement cavities contains a large number of air bubbles, especially in areas such as corners of the formwork and around the reinforcing bars, where gaps are easily formed. The vibration of the upper plate, which drives the upper wall plate, and the vibration of the lower plate, which drives the lower wall plate, will generate an impact force on the uncured concrete in the first and second placement cavities. This impact force breaks the surface tension of the air bubbles and water inside the concrete, causing the air bubbles to rise and be discharged, thereby stabilizing the internal structure of the concrete products.

Description

Technical Field

[0001] This invention belongs to the field of concrete processing technology, specifically referring to a concrete processing vibration exhaust device. Background Technology

[0002] A stilling cone is a concrete product mainly installed at the outlet of spillways, drainage outlets, or flood discharge tunnels. Through its conical design, it disperses the energy of the water flow, reducing the scouring and damage to downstream areas. It is characterized by corrosion resistance, impact resistance, and suitability for long-term immersion environments.

[0003] Normally, during the production of concrete products, vibrators are used to remove air bubbles from the poured concrete. However, the conical structure has a narrow inner cavity, making it difficult for the vibrator to penetrate deeply. If the concrete solidifies at this time, numerous tiny air bubbles will appear inside the stilling cone, which will reduce the overall structural integrity of the stilling cone.

[0004] Insufficient overall integrity of the stilling cone structure can lead to uneven stress distribution within the concrete, making weak areas prone to cracking. Under the impact of high-speed water flow, these cracks propagate rapidly, eventually causing structural collapse or fracture. Summary of the Invention

[0005] In view of the above situation and to overcome the defects of the prior art, the present invention provides a concrete processing vibration exhaust device, which at least partially solves the above problems.

[0006] The technical solution adopted by the present invention is as follows: The present invention proposes a concrete processing vibration exhaust device, including an upper plate, a lower plate and a vibration transmission component, wherein the upper plate is disposed on the upper part of the lower plate and the vibration transmission component is disposed between the upper plate and the lower plate.

[0007] The vibration transmission assembly is used to cause the upper and lower plates to vibrate.

[0008] The upper and lower plates are used to fix cement products.

[0009] Furthermore, the vibration transmission assembly includes a built-in cavity, a mounting column, an elastic damper, a moving column, a power assembly, and a limiting block. The built-in cavity is fixed to the lower part of the vibration transmission assembly and is a hollow cylinder. The moving column is located inside the built-in cavity and can slide up and down inside the cavity. The moving column is hollow inside. A limiting block is fixed to the upper part of the moving column, and the limiting block has a hole at its center. The mounting column passes through the hole at the center of the limiting block, and the upper part of the mounting column is fixed to the bottom of the vibration transmission assembly. An elastic damper is installed between the bottom of the mounting column and the limiting block. The power assembly is fixed to the bottom of the moving column, and the bottom of the mounting column is fixed to the upper part of the power assembly.

[0010] Furthermore, the upper plate includes an upper collar, a first placement cavity, an upper wall plate, a first mounting collar, and an upper locking plate. The concrete processing vibration exhaust device includes two upper plates, each of which is rectangular and has a semi-circular notch at its center. An upper collar is fixedly connected to the upper part of each upper plate. The upper collar is semi-circular, and its radius is the same as the radius of the semi-circular notch at the center of the upper plate. An upper locking plate is fixedly connected to both sides of each upper collar. An upper wall plate is fixedly connected to the lower part of each upper collar. The center of the two sets of upper wall plates is the first placement cavity. Two sets of first mounting collars are symmetrically fixed to the lower part of each upper plate.

[0011] Furthermore, the lower assembly plate includes a lower wall plate, a fourth mounting collar, a second placement cavity, and a lower locking plate. The concrete processing vibration exhaust device includes two lower assembly plates, each with a semi-circular notch at its center. Each set of lower assembly plates has a lower wall plate at its upper part, with a semi-circular bottom and the radius of the semi-circular notch being the same as the radius of the semi-circular notch at the center of the lower assembly plate. Two sets of fourth mounting collars are symmetrically fixed to the upper part of each lower assembly plate, and a set of lower locking plates is fixed to both sides of each set of lower wall plates. The center of the two sets of lower wall plates is the second placement cavity.

[0012] Furthermore, two sets of second mounting collars are symmetrically fixed to the upper part of the vibration transmission component, and two sets of third mounting collars are symmetrically fixed to the lower part of the vibration transmission component.

[0013] Furthermore, an upper spring is provided between each of the two sets of second mounting collars and the two sets of first mounting collars, and a lower spring is provided between each of the two sets of third mounting collars and the two sets of fourth mounting collars.

[0014] Furthermore, a set of cranks is rotatably connected to the lower part of the power assembly, a crankshaft is rotatably connected to the lower part of the cranks, and a movable wheel is fixedly connected to the tail of the crankshaft.

[0015] Furthermore, the radius of the semi-circular notch at the center of the upper plate is smaller than the radius of the semi-circular notch at the center of the lower plate.

[0016] The beneficial effects achieved by the present invention using the above structure are as follows: (1) The uncured concrete in the first and second placement cavities contains a large number of air bubbles, especially in the corners of the formwork and around the reinforcing bars, which are prone to forming gaps. The vibration of the upper wall plate driven by the upper plate and the vibration of the lower wall plate driven by the lower plate will generate an impact force on the uncured concrete in the first and second placement cavities. This impact force destroys the air bubbles and surface tension of water inside the concrete, causing the air bubbles to rise and be discharged, thereby stabilizing the internal structure of the concrete product. (2) After the uncured concrete in the first and second placement cavities is subjected to the impact force brought by external vibration, the uncured concrete aggregate (sand, stone) and cement paste in the first and second placement cavities rearrange under vibration, fill the gaps, significantly improve the density, and the vibration causes the concrete to liquefy (temporarily exhibit fluid-like properties), and the aggregate and paste are evenly mixed; reducing material separation caused by gravity and ensuring the overall composition of the concrete is uniform.

Therefore, they should not be construed as limitations on this invention.

[0022] like Figures 1 to 6 As shown, the present invention proposes a concrete processing vibration exhaust device, including an upper plate 1, a lower plate 12 and a vibration transmission component 17. The upper plate 1 is disposed on the upper part of the lower plate 12, and the vibration transmission component 17 is disposed between the upper plate 1 and the lower plate 12. The vibration transmission component 17 is used to cause the upper plate 1 and the lower plate 12 to vibrate. The upper plate 1 and the lower plate 12 are used to fix cement products.

[0023] Furthermore, the vibration transmission assembly 17 includes an internal cavity 18, a mounting column 19, an elastic damper 20, a moving column 21, a power assembly 22, and a limiting block 25. The internal cavity 18 is fixed to the lower part of the vibration transmission assembly 17. The internal cavity 18 is a hollow cylinder. The moving column 21 is located inside the internal cavity 18 and can slide up and down inside the internal cavity 18. The moving column 21 is hollow inside. The upper part of the moving column 21 is fixed to the limiting block 25. The limiting block 25 has a hole at its center. The mounting column 19 passes through the hole at the center of the limiting block 25, and the upper part of the mounting column 19 is fixed to the bottom of the vibration transmission assembly 17. An elastic damper 20 is installed between the bottom of the mounting column 19 and the limiting block 25. The power assembly 22 is fixed to the bottom of the moving column 21, and the bottom of the mounting column 19 is fixed to the upper part of the power assembly 22.

[0024] Furthermore, the upper plate 1 includes an upper collar 2, a first placement cavity 3, an upper wall plate 4, a first mounting collar 5, and an upper locking plate 16. The concrete processing vibration exhaust device includes two upper plates 1, each of which is rectangular and has a semi-circular notch at its center. An upper collar 2 is fixedly connected to the upper part of each upper plate 1. The upper collar 2 is semi-circular, and its radius is the same as the radius of the semi-circular notch at the center of the upper plate 1. An upper locking plate 16 is fixedly connected to both sides of each upper collar 2. An upper wall plate 4 is fixedly connected to the lower part of each upper collar 2. The center of the two sets of upper wall plates 4 is the first placement cavity 3. Two sets of first mounting collars 5 are symmetrically fixed to the lower part of each upper plate 1.

[0025] Furthermore, the lower plate 12 includes a lower wall plate 8, a fourth mounting collar 13, a second placement cavity 14, and a lower locking plate 15. The concrete processing vibration exhaust device includes two lower plates 12. Both lower plates 12 have a semi-circular notch at their center. Each set of lower plates 12 has a lower wall plate 8 at its upper part. The bottom of the lower wall plate 8 is semi-circular, and the radius of the semi-circular notch is the same as the radius of the semi-circular notch at the center of the lower plate 12. Two sets of fourth mounting collars 13 are symmetrically fixed to the upper part of each lower plate 12. A set of lower locking plates 15 are fixed to both sides of each set of lower wall plates 8. The center of the two sets of lower wall plates 8 is the second placement cavity 14.

[0026] Furthermore, two sets of second mounting collars 9 are symmetrically fixed to the upper part of the vibration transmission component 17, and two sets of third mounting collars 10 are symmetrically fixed to the lower part of the vibration transmission component 17.

[0027] Furthermore, an upper spring 6 is provided between each of the two sets of second mounting collars 9 and the two sets of first mounting collars 5, and a lower spring 11 is provided between each of the two sets of third mounting collars 10 and the two sets of fourth mounting collars 13.

[0028] Furthermore, a set of cranks 26 are rotatably connected to the lower part of the power assembly 22, and a crankshaft 23 is rotatably connected to the lower part of the cranks 26. A movable wheel 24 is fixedly connected to the tail of the crankshaft 23.

[0029] Furthermore, the radius of the semi-circular notch at the center of the upper plate 1 is smaller than the radius of the semi-circular notch at the center of the lower plate 12.

[0030] In this embodiment, a set of cranks 26 are rotatably connected to the lower part of the power assembly 22, and a crankshaft 23 is rotatably connected to the lower part of the cranks 26. A movable wheel 24 is fixedly connected to the tail of the crankshaft 23. At this time, the movable wheel 24 is connected to an external motor through a power belt. When the external motor is started, it begins to rotate. Then, the rotation of the external motor drives the power belt to rotate, and finally the power belt drives the movable wheel 24 to rotate.

[0031] When the rotating wheel 24 starts to rotate, since the rotating wheel 24 is connected to the crankshaft 23, when the rotating wheel 24 starts to rotate under the external drive, it will drive the crankshaft 23 to rotate. The lower part of the crank 26 is rotatably connected to the crankshaft 23. When the crankshaft 23 rotates, it will cause the crank 26 to rotate.

[0032] Due to the inherent characteristics of the crankshaft 23, when the crankshaft 23 rotates, the crank 26 connected to it will also move up and down during the rotation process. The bottom of the power assembly 22 is connected to the crank 26 in a rotating manner, so when the crank 26 moves up and down, it will drive the power assembly 22 to move up and down.

[0033] Furthermore, since the power component 22 is fixed to the bottom of the moving column 21, when the crank 26 moves up and down, the moving column 21 will follow the power component 22 to move up and down. Then, since the upper part of the moving column 21 is fixed to the limit block 25, when the moving column 21 moves up and down, it will drive the limit block 25 to move up and down.

[0034] Furthermore, since the limiting block 25 has a hole at its center, the mounting post 19 passes through the hole at the center of the limiting block 25. An elastic damper 20 is installed between the bottom of the mounting post 19 and the limiting block 25. When the limiting block 25 moves downward in a straight line under the influence of external forces, the elastic damper 20 located between the bottom of the mounting post 19 and the limiting block 25 will accumulate elastic force. Then, when the limiting block 25 moves upward, the accumulated elastic force of the elastic damper 20 will be released.

[0035] The elastic damper 20 is located outside the mounting post 19. When the elastic damper 20 accumulates elastic force, it will be released and the elastic force will act on the mounting post 19. The upper part of the mounting post 19 is fixed to the bottom of the vibration transmission assembly 17. When the elastic force acts on the mounting post 19, it will be transmitted from the mounting post 19 to the vibration transmission assembly 17.

[0036] The upper part of the vibration transmission component 17 is symmetrically fixed with two sets of second mounting collars 9, and the lower part of the vibration transmission component 17 is symmetrically fixed with two sets of third mounting collars 10. Each set of second mounting collars 9 is provided with an upper spring 6 between the two sets of first mounting collars 5, and each set of third mounting collars 10 is provided with a lower spring 11 between the two sets of fourth mounting collars 13.

[0037] After the elastic force is transmitted from the mounting post 19 to the vibration transmission assembly 17, the elastic force will be transmitted from the vibration transmission assembly 17 to the second mounting collar 9 and the third mounting collar 10, and then from the second mounting collar 9 and the third mounting collar 10 to the upper spring 6 and the lower spring 11 respectively, and finally from the upper spring 6 and the lower spring 11 to the first mounting collar 5 and the fourth mounting collar 13.

[0038] Two sets of first mounting rings 5 ​​are symmetrically fixed to the lower part of each upper plate 1. At this time, the elastic force will be transmitted to the upper plate 1 through the first mounting rings 5. Two sets of fourth mounting rings 13 are symmetrically fixed to the upper part of each lower plate 12. Finally, each lower plate 12 will receive the elastic force from the fourth mounting rings 13.

[0039] This elastic force will eventually cause the upper plate 1 and the lower plate 12 to vibrate. The upper part of the upper plate 1 is fixed with an upper collar 2, and the two sides of each upper collar 2 are fixed with an upper locking plate 16. The lower part of each upper collar 2 is fixed with an upper wall plate 4. The center of the two sets of upper wall plates 4 is the first placement cavity 3. When the two upper wall plates 4 are locked by the upper locking plate 16 and the concrete is poured into the first placement cavity 3, the upper plate 1 with elastic force will drive the upper wall plate 4 to vibrate, and the upper wall plate 4 will gradually vibrate the uncured concrete in the first placement cavity 3.

[0040] Furthermore, each set of lower composite plates 12 is provided with a lower wall plate 8 on its upper part. The center of the two sets of lower wall plates 8 is the second placement cavity 14. At this time, the concrete from the first placement cavity 3 will eventually fall into the second placement cavity 14 until the first placement cavity 3 and the second placement cavity 14 are filled. The lower composite plate 12 will then drive the lower wall plate 8 to vibrate the uncured concrete in the second placement cavity 14.

[0041] At this time, the uncured concrete in the first placement cavity 3 and the second placement cavity 14 contains a large number of air bubbles, especially in the corners of the formwork and around the reinforcing bars, where voids are easily formed. The vibration of the upper wall plate 4 driven by the upper plate 1 and the vibration of the lower wall plate 8 driven by the lower plate 12 will generate an impact force on the uncured concrete in the first placement cavity 3 and the second placement cavity 14. This impact force breaks the surface tension of the air bubbles and water inside the concrete, causing the air bubbles to rise and be discharged, thereby stabilizing the internal structure of the concrete product.

[0042] Furthermore, when the uncured concrete in the first placement cavity 3 and the second placement cavity 14 is subjected to the impact force brought about by external vibration, the uncured concrete aggregates (sand, stone) and cement paste in the first placement cavity 3 and the second placement cavity 14 rearrange under vibration, fill the gaps, significantly improve the density, and the vibration causes the concrete to liquefy (temporarily exhibiting fluid-like properties), and the aggregates and paste are evenly mixed; reducing material separation caused by gravity and ensuring the overall uniformity of the concrete composition.
