Description

Technical Field

[0001] The invention relates to the technical field of recycled aggregate concrete molding, in particular to a recycled aggregate concrete molding device. Background Art

[0002] As an environmentally friendly building material, recycled concrete is gradually becoming an important choice for urban construction and renewal. It realizes the reuse of resources by crushing, carefully cleaning and scientifically grading discarded concrete blocks. In this process, discarded concrete blocks are converted into recycled aggregates, which can partially or completely replace traditional natural aggregates such as sand and gravel. Subsequently, these recycled aggregates are mixed according to specific proportions and gradings, and appropriate amounts of cement and water are added. After sufficient mixing and molding, new concrete with excellent performance is finally made. It is worth mentioning that the permeable bricks commonly seen in urban roads are made of this recycled aggregate concrete. In order to achieve this process, professional recycled aggregate concrete molding devices are indispensable. These devices ensure that recycled aggregate concrete can be efficiently molded, providing solid technical support for the widespread application of recycled concrete in urban construction.

[0003] In the current manufacturing process of permeable bricks, when recycled concrete is used as the main raw material, although the recycling of waste has been achieved to a certain extent, its production process still has a significant lack of automation. Specifically, the entire manufacturing process, from raw material preparation to the output of the final product, most steps still require a large amount of direct manual participation, which not only increases production costs, but also limits the improvement of production efficiency. In the raw material filling stage, workers need to first manually fix the mold to ensure its stability, and then add the prepared recycled concrete and other ingredients into the mold one by one. Then, when vibrating and leveling, they also need to rely on the workers' experience and skills, which not only increases the possibility of human errors, but also affects the quality consistency of the permeable brick products. Finally, the demolding operation is carried out. Each link cannot be separated from the direct intervention of a large number of people, which seriously restricts the further improvement of production efficiency. Summary of the invention

[0066] The vibrating and compacting assembly 9 is arranged on the displacement end of the vertical reciprocating moving assembly 8, and is used to compact the recycled aggregate concrete in the recycled aggregate concrete casting and molding area.

[0067] The device is first based on the base 1, and its horizontal positioning surface provides stable support for the entire device. On the positioning surface of the base 1, there are fixedly installed no less than four legs 2 that are symmetrically distributed according to the center of the base 1. These legs 2 not only provide the necessary support height for the device, but also ensure the stability and balance of the entire device. Between the four legs 2, there is an outer frame 3 that is arranged in an overall U-shaped shape. A bottom template 4 is fixedly installed on the inner side of the outer frame 3. The bottom template 4 serves as the basis for the molding of recycled aggregate concrete, and its flatness and stability are crucial to subsequent operations. On the inner side of the outer frame 3, there are also four side templates 5. These side templates 5 are symmetrically distributed according to the center of the base 1, and one end of one side is in contact with the surface of the bottom template 4.

The device is first based on the base 1, and its horizontal positioning surface not only provides a stable support for the entire device, but also a profile frame 10 is fixedly installed on this basis. The design of the profile frame 10 provides a stable installation platform for the hydraulic push rod 11, and also ensures the stability and accuracy of the hydraulic push rod 11 during the working process. The hydraulic push rod 11 is arranged throughout the profile frame 10, and its driving end faces the side of the recycled aggregate concrete casting and molding area, which means that the working direction of the hydraulic push rod 11 is toward the concrete in the casting and molding area, which provides necessary power support for subsequent extrusion operations, and an extrusion plate 12 is also fixedly installed on the output end of the hydraulic push rod 11. The design of the extrusion plate 12 The purpose is to extrude the concrete in the casting and molding area of ​​the recycled aggregate concrete under the drive of the hydraulic push rod 11. The purpose of this step is to further improve the density and strength of the concrete, so as to ensure that the final concrete products such as permeable bricks have better performance and quality. When the recycled aggregate concrete is filled into the casting and molding area formed by the bottom template 4 and the four side templates 5, the scraping component 7 will first work to smooth the concrete surface.

[0071] The hydraulic pump body 62 is fixedly mounted on the positioning surface of the base 1, wherein the oil suction end of the hydraulic pump body 62 penetrates and extends to the inner side of the hydraulic oil tank 61;

[0072] The oil delivery pipe 63 is arranged on the oil delivery end of the hydraulic pump body 62, wherein the other end of the oil delivery pipe 63 is connected to the equalizing pipe 64 located outside the outer frame 3 through the first three-way joint, and the entire equalizing pipe 64 is arranged in a square shape, and a first solenoid valve is also arranged outside the equalizing pipe 64;

[0073] A piston push rod 65 is provided through the outer frame 3 and is connected to the side template 5; and

[0074] The return oil pipe 66 is connected to the equalizing pipe 64 at one end and to the hydraulic oil tank 61 at the other end. A second solenoid valve is also provided on the outer side of the return oil pipe 66. The hydraulic oil drive assembly 6 is a key component in the entire recycled aggregate concrete forming device. It is responsible for driving the side formwork 5 to move closer to the center to form a recycled aggregate concrete casting and forming area. The assembly is mainly composed of a hydraulic oil tank 61, a hydraulic pump body 62, an oil delivery pipe 63, an equalizing pipe 64, a piston push rod 65 and a return oil pipe 66. The hydraulic oil tank 61 is fixedly installed on the positioning surface of the base 1, and its inner side is filled with hydraulic oil, which provides the entire hydraulic oil drive system. The necessary hydraulic energy is provided. The hydraulic pump body 62 is also fixedly installed on the positioning surface of the base 1. Its oil suction end penetrates and extends to the inner side of the hydraulic oil tank 61, and is responsible for extracting the hydraulic oil in the hydraulic oil tank 61 and pressurizing and delivering it to other components. The oil delivery pipe 63 is arranged on the oil delivery end of the hydraulic pump body 62, and is responsible for delivering the pressurized hydraulic oil to the equalizing pipe 64. The equalizing pipe 64 is arranged in a mouth shape, located on the outer side of the outer frame 3, and is connected to the oil delivery pipe 63 through the first three-way joint. The outer side of the equalizing pipe 64 is also provided with a first solenoid valve for controlling the inflow and outflow of the hydraulic oil. The piston push rod 65 is arranged on the outer frame 3 and is connected to the side template. 5 are interconnected. When the hydraulic oil flows into the inner side of the piston push rod 65 through the equalizing pipe 64, the piston push rod 65 will be pushed outward, thereby driving the four side templates 5 to move closer to the center to form a recycled aggregate concrete casting and molding area. One end of the return oil pipe 66 is interconnected with the equalizing pipe 64, and the other end is interconnected with the hydraulic oil tank 61, which is used to return the hydraulic oil inside the piston push rod 65 to the hydraulic oil tank 61. A second solenoid valve is arranged on the outer side of the return oil pipe 66 to control the reflux of the hydraulic oil. In the use process, the second solenoid valve is first closed, the first solenoid valve is opened, and then the hydraulic pump body 62 is started. The hydraulic pump body 62 returns the hydraulic oil to the hydraulic oil tank 61. The hydraulic oil in the oil pressure tank 61 is extracted and pressurized, and is transported to the equalizing pipe 64 through the oil delivery pipe 63, and then flows into the inner side of the piston push rod 65. As the hydraulic oil continues to flow in, the piston push rod 65 extends outward, driving the four side templates 5 to move closer to the center to form a recycled aggregate concrete casting and molding area. When the four side templates 5 approach each other and reach a predetermined position, the first solenoid valve is closed to stop the inflow of hydraulic oil. At this time, the entire hydraulic oil fills the inner side of the piston push rod 65, limiting the four side templates 5 to ensure that they can stably remain in the predetermined position, providing necessary support and guarantee for subsequent casting and molding operations.

[0075] In a preferred embodiment, the present invention can be further configured as follows: Figure 3 , Figure 4 As shown; the piston push rod 65 comprises:

[0076] The outer cylinder 651 is disposed through the outer frame 3, wherein two outer cylinders 651 are disposed on each of the four sides of the outer frame 3;

This design enables the fixing sleeve 13 to be firmly attached to the scraper 73, providing a reliable installation foundation for the subsequent corrugated telescopic feed hose 14. A corrugated telescopic feed hose 14 is penetrated on the fixing sleeve 13. One end of the corrugated telescopic feed hose 14 can be connected to the concrete conveying equipment, and the other end can be connected to the concrete conveying equipment. The end extends to the vicinity of the working area of ​​the scraper 73. While the scraper 73 is performing the smoothing operation, the corrugated telescopic feed hose 14 can be telescopically adjusted according to the movement of the scraper 73 and the filling requirements of the concrete, ensuring that the concrete can be evenly and continuously transported to the designated position in front of the scraper 73. Since the corrugated telescopic feed hose 14 has excellent elasticity and wear resistance, it can well adapt to the displacement and deformation of the scraper 73 during the movement, while ensuring that the transportation of the concrete is not affected. In this way, in the process of the scraper 73 smoothing the concrete, the corrugated telescopic feed hose 14 can continuously provide fresh concrete to the area in front of the scraper 73, making the concrete in the entire molding area more uniform and dense, thereby improving the working efficiency and finished product quality of the recycled aggregate concrete molding device.

At this time, the second return spring 81 is compressed and stores energy. When the scraper 73 is not in contact with the transmission plate 84 and moves between two adjacent transmission plates 84, the second return spring 81 releases energy to reset, thereby driving the movable plate 82 and the bottom template 4 to move upward. Since several transmission plates 84 are provided, the scraper 73 will continuously contact and separate from different transmission plates 84 during the displacement process, thereby reciprocatingly driving the movable plate 82 to move up and down.

The vibrating and compacting component 9 is a key part of the recycled aggregate concrete forming device, which is responsible for vibrating and compacting the recycled aggregate concrete to improve the density and uniformity of the concrete. The component is mainly composed of a straight pipe 91, a sleeve 92, a sleeve rod 93, a vibrating protrusion 94, a return pipe 95, an oil inlet pipe 96 and a branch pipe 97. There are two straight pipes 91, both of which are fixed. It is installed on the side surface of the movable plate 82 away from the second return spring 81, and the two straight tubes 91 are arranged parallel to each other. This design ensures that the vibrating and tamping assembly 9 can be stably installed on the movable plate 82 and move with the up and down movement of the movable plate 82. The sleeve 92 is welded on the straight tube 91 and is interconnected with the straight tube 91. There are several sleeves 92, which are equally divided into two groups and are respectively arranged on the opposite side surfaces of the two straight tubes 91. The design of the sleeve 92 provides space for the telescopic sliding of the sleeve rod 93. One end of the sleeve rod 93 is arranged on the inner side of the sleeve 92 of one of the straight tubes 91, and the other end is arranged on the other straight tube 91. The inner side of the sleeve 92 of the pipe 91 is matched with the sleeve 92 in number and distribution position. The two adjacent sleeve rods 93 are arranged parallel to each other. The sleeve rod 93 is retractably and slidably connected to the inner side of the sleeve 92. Such a design enables the sleeve rod 93 to move left and right under the drive of hydraulic oil. The vibrating protrusion 94 is fixedly mounted on the surface of the sleeve rod 93 and is located between the two straight pipes 91. The vibrating protrusion 94 is the working part of the vibrating and compacting component 9. It vibrates the concrete as the sleeve rod 93 moves. One end of the return pipe 95 is connected to the straight pipe 91, and the other end is connected to the hydraulic oil tank 61. The number and distribution position of the return pipe 95 are matched with the sleeve 92. The adjacent sleeve rods 93 are arranged parallel to each other. The sleeve rod 93 is retractably and slidably connected to the inner side of the sleeve 92. Such a design enables the sleeve rod 93 to move left and right under the drive of hydraulic oil. The vibrating protrusion 94 is fixedly mounted on the surface of the sleeve rod 93 and is located between the two straight pipes 91. The vibrating protrusion 94 is the working part of the vibrating and compacting component 9. It vibrates the concrete as the sleeve rod 93 moves. The return pipe 95 is connected to the straight pipe 91 at one end, and is connected to the hydraulic oil tank 61 at the other end. The distribution position is adapted to the straight pipe 91, and a third solenoid valve is fixedly installed on the surface of the return pipe 95 for controlling the reflux of the hydraulic oil. One end of the oil inlet pipe 96 is interconnected with the other end of the first three-way joint, and the other end is connected to the second three-way joint. The oil inlet pipe 96 is responsible for pumping the hydraulic oil from the hydraulic oil tank 61 to the vibrating and compacting component 9. One end of the branch pipe 97 is interconnected with the straight pipe 91, and the other end is interconnected with the second three-way joint. The number and distribution position are adapted to the straight pipe 91. A fourth solenoid valve is fixedly installed on the surface of the branch pipe 97 for controlling the inflow of the hydraulic oil. During use, according to Figure 7As shown, the hydraulic pump body 62 draws the hydraulic oil in the hydraulic oil tank 61 into the oil inlet pipe 96 through the first three-way joint, and then opens the fourth solenoid valve on the right, closes the fourth solenoid valve on the left, and closes the third solenoid valve on the right, and opens the third solenoid valve on the return pipe 95 on the left, so that the hydraulic oil can enter the inner side of the right branch pipe 97 and the straight pipe 91. Driven by the hydraulic oil, the entire sleeve rod 93 and the vibrating protrusion 94 can be pushed to move left. At the same time, the hydraulic oil in the left branch pipe 97 and the straight pipe 91 can flow into the hydraulic oil tank 61 again through the return pipe 95, forming a circulating flow of the hydraulic oil. When the vibrating protrusion 94 moves to the specified position, all the third solenoid valves and the fourth solenoid valves are closed, so that the hydraulic oil fills the inner side of the sleeve 92, fixes the position of the vibrating protrusion 94, and controls the straight pipes 91 on the left and right sides through the gap. 1 and the oil amount in the control return pipe 95 can be adjusted to different positions of the vibrating protrusion 94, so as to vibrate different positions in the casting and molding area of ​​the recycled aggregate concrete, thereby improving the overall vibration effect. The specific control method is: when the vibrating protrusion 94 is located at the center of the two straight pipes 91, the oil amounts in the two straight pipes 91 and the two sleeve rods 93 are the same. When the position of the vibrating protrusion 94 needs to be changed, more hydraulic oil should be added to the straight pipe 91 and the sleeve rod 93 on one side, while the hydraulic oil in the straight pipe 91 and the sleeve rod 93 on the other side should be reduced accordingly. When the displacement is to the specified position, all the third solenoid valves and the fourth solenoid valves can be closed. Therefore, during the casting process, the position of the vibrating protrusion 94 can be specifically controlled by accurately controlling the switching states of the third solenoid valve and the fourth solenoid valve, so as to achieve effective vibration and compaction of the concrete.

[0099] In a preferred embodiment, the present invention can be further configured as follows: Figure 4 , Figure 5As shown; a vibration transmission plate 15 is fixedly installed on one side surface of the bottom template 4, wherein the vibration protrusion 94 can contact with the side surface of the vibration transmission plate 15 away from the bottom template 4, wherein the vibration transmission plate 15 can be made of rubber. When the vibration protrusion 94 in the vibration assembly contacts with the side surface of the vibration transmission plate 15 away from the bottom template 4 and vibrates, the vibration transmission plate 15 made of rubber can effectively absorb and disperse the impact force. This feature not only reduces the direct damage of the vibration energy to the bottom template 4, but also improves the transmission efficiency of the vibration energy. Specifically, the vibration transmission plate 15 can efficiently transfer the vibration energy generated by the vibration protrusion 94 to the concrete, so that the internal particles of the concrete are rearranged under the action of vibration and reach a dense state. The main function of the vibration transmission plate 15 is to improve the transmission efficiency of the vibration energy, which is different from the traditional Compared with the method of directly knocking on the bottom formwork 4, transmitting vibration energy through the vibration transfer plate 15 can reduce the loss and dispersion of energy during the transmission process, thereby ensuring that more vibration energy can act on the concrete and improve the vibration effect. This improvement not only helps to improve the quality of concrete, but also reduces energy consumption and production costs. In addition, the vibration transfer plate 15 can also significantly reduce the risk of damage to the formwork. During the vibration process, the impact of the knocking hammer on the vibration transfer plate 15 will be absorbed and dispersed by the rubber material, thereby reducing the direct impact on the bottom formwork 4. This design not only extends the service life of the formwork, but also reduces the cost of repairing and replacing the formwork. At the same time, since the rubber material usually has good elasticity and wear resistance, the vibration transfer plate 15 can maintain stable performance during long-term use, ensuring the continuity and stability of the vibration effect.

[0100] The specific working principle of a recycled aggregate concrete forming device of the present invention is as follows:

[0101] First, place the recycled aggregate concrete forming device in a suitable position to ensure that the base 1 is stable and level. Next, close the second solenoid valve on the oil return pipe 66, open the first solenoid valve, start the hydraulic pump body 62, and the hydraulic pump body 62 extracts hydraulic oil from the hydraulic oil tank 61 through the oil suction end, and delivers it to the first three-way joint through the oil delivery pipe 63, and then divides it to the equalizing pipe 64. The equalizing pipe 64 evenly distributes the hydraulic oil to each connecting pipe 654, and then enters the outer cylinder 651, pushing the piston push rod 652 to move outward, so that the four side templates 5 are close to the center of the bottom template 4, forming a recycled aggregate concrete casting and forming area;

[0102] When the four side templates 5 are close to each other and fit closely, the first solenoid valve is closed to stop the hydraulic oil from being delivered to the inner side of the piston push rod 65. At this time, the entire hydraulic oil is filled in the inner side of the piston push rod 65 to limit the position of the four side templates 5 and keep them stable and motionless.

[0103] Next, the recycled aggregate concrete is transported to the recycled aggregate concrete casting and molding area through the corrugated telescopic feeding hose 14. During the transportation process, the driving motor 74 can be started, and the driving motor 74 drives the two reciprocating screws 71 to rotate through the chain transmission assembly, thereby driving the two threaded sleeves 72 and the scraper 73 to move along the length direction of the reciprocating screw 71, so as to smooth the recycled aggregate concrete in the recycled aggregate concrete casting and molding area;

[0104] During the displacement of the scraper 73, when the scraper 73 and the transmission plate 84 are in contact with each other, the entire movable plate 82 is pushed to move downward, and the second return spring 81 is compressed at this time. When the scraper 73 is not in contact with one of the transmission plates 84 and is located between two adjacent transmission plates 84, the second return spring 81 is reset, thereby driving the movable plate 82 to move upward. Since a plurality of transmission plates 84 are provided, the movable plate 82 can be driven to move up and down reciprocatingly.

[0105] During the leveling process of recycled aggregate concrete, vibration work begins at the same time. Figure 7 As shown, the hydraulic pump body 62 is started again, so that the hydraulic oil in the hydraulic oil tank 61 is pumped into the oil inlet pipe 96 through the first three-way joint, and then, according to the position to be vibrated, the fourth solenoid valve on the right is opened, the fourth solenoid valve on the left is closed, and the third solenoid valve on the right is closed at the same time, and the third solenoid valve on the left is opened, so that the hydraulic oil can enter the inner side of the right branch pipe 97 and the straight pipe 91, and the entire sleeve rod 93 and the vibrating protrusion 94 are pushed to move to the left under the drive of the hydraulic oil. At the same time, the hydraulic oil in the left branch pipe 97 and the straight pipe 91 can flow into the hydraulic oil tank 61 again through the return pipe 95, forming a circulation of the hydraulic oil;

[0106] When the vibrating protrusion 94 moves to the designated position, all the third solenoid valves and the fourth solenoid valves are closed. At this time, the hydraulic oil fills the inner side of the sleeve 92, and the position of the vibrating protrusion 94 is fixed. By controlling the oil amount in the straight pipes 91 on the left and right sides and the oil amount in the return pipe 95 through the gap, the vibrating protrusion 94 can be adjusted to different positions, so as to vibrate different positions in the casting and molding area of ​​the recycled aggregate concrete, thereby improving the overall vibration effect;

[0107] During the vibration process, the vibration protrusion 94 will contact the vibration transmission plate 15 and transmit the vibration energy to the concrete. Since the vibration transmission plate 15 is made of rubber, it can effectively absorb and disperse the impact force and reduce the damage of the vibration to the bottom formwork 4. At the same time, the vibration transmission performance of rubber is also good, and the vibration energy generated by the vibration protrusion 94 can be efficiently transmitted to the concrete, so that the particles inside the concrete are rearranged and reach a dense state.

[0108] Finally, when the recycled aggregate concrete is vibrated and compacted, the second solenoid valve can be opened to allow the hydraulic oil to flow back to the hydraulic oil tank 61 from the inside of the piston push rod 65, and the first return spring 653 will use its stored elastic potential energy to reset, pulling the piston push rod 652 back into the outer tube 651, thereby pulling the side formwork 5 to the surroundings, completing the demoulding operation, opening the recycled aggregate concrete casting and molding area, and taking out the molded concrete components. At this point, the use process of the entire recycled aggregate concrete molding device is completed.
