Description

TECHNICAL FIELD

[0002] With the acceleration of industrialization process, the construction industry has higher requirements for production efficiency and quality. Prefabricated concrete, as an industrialized building production method, can greatly improve production efficiency, reduce the difficulty and time of on-site construction, and thus meet the needs of the industrialization process for the construction industry. Traditional on-site pouring concrete has problems such as material waste and unstable quality. Prefabricated concrete can more accurately control the material ratio and production process of concrete under factory production conditions, thereby saving resources and improving the quality of concrete.

[0003] When using low-flow prefabricated phosphogypsum concrete (hexagonal block), the concrete is mainly mixed with coarse sand, cement, and a certain amount of water.

DETAILED DESCRIPTION

[0030] The application will be further described below in conjunction with the drawings and specific embodiments.

[0031] Embodiment: The prefabricated phosphogypsum concrete pouring forming mold, as shown in Figure 1 and Figure 2 , comprises a workbench 1, a hexagonal mold 11, a support plate 12, a buffer spring 13, a buffer frame 14, a top plate 15, a placement plate 16, a limiting assembly 2, a blanking mechanism 3 and a compaction mechanism 4. The workbench 1 is one meter high from the ground. The hexagonal mold 11 is formed by a plurality of hexagonal frames fixed together. The hexagonal mold 11 is fixed at the top of the workbench 1 at both ends. Four support plates 12 are fixed at the left and right sides inside the workbench 1. The buffer frame 14 is slidingly connected to the support plate 12. The buffer frame 14 has a round plate at the top and the bottom. The round plates are connected by a round rod in the middle. The top round plates are connected by a long plate. The buffer spring 13 is sleeved in the buffer frame 14. One end of the buffer spring 13 is connected to the support plate 12, and the other end is connected to the buffer frame 14. The top plate 15 is arranged inside the workbench 1 below. The distance between the top plate 15 and the support plate 12 is greater than the height of the buffer spring 13 after being completely compressed. Therefore, the top plate 15 supports the object at the top before the buffer spring 13 is completely compressed. The placement plate 16 is arranged at the top of the buffer frame 14. The placement plate 16 is tightly attached to the bottom of the hexagonal mold 11. The surface of the placement plate 16 is smooth and has high strength and is not easy to bend. The limiting assembly 2 is arranged at both sides of the workbench 1 to limit the movement of the buffer frame 14. The blanking mechanism 3 is arranged on the workbench 1 to move the blanking pipe. The compaction mechanism 4 is arranged on the blanking mechanism 3 to compact the concrete.

[0032] As shown in Figure 1 , Figure 3 and Figure 4As shown in the drawings, the limiting assembly 2 comprises a connecting plate 21, a limiting frame 22, a limiting rod 23 and an elastic member a 24. The limiting rod 23 is fixedly connected to the outer side of the upper end of the workbench 1. The limiting frame 22 is slidingly connected to the limiting rod 23. The end of the limiting frame 22 penetrates through the workbench 1. The part of the workbench 1 into which the end of the limiting frame 22 extends is inclined at the bottom and flat at the top. The connecting plate 21 is fixedly connected to the top of the left and right sides of the buffer frame 14. The limiting frame 22 is slidingly connected to the connecting plate 21. The connecting plate 21 is provided with a groove. The end of the limiting plate can be inserted into the groove of the connecting plate 21 to support and limit the limiting plate. The elastic member a 24 is sleeved on the limiting rod 23. One end of the elastic member a 24 is fixedly connected to the outer side of the workbench 1. The other end of the elastic member a 24 is fixedly connected to the limiting frame 22.

[0033] As shown in the drawings, Figure 5 , Figure 6 and Figure 10 , the blanking mechanism 3 comprises a blanking pipe 31, a sliding block 32 and a guide frame 33. The guide frame 33 is fixedly connected to the top of the workbench 1. The sliding block 32 is slidingly connected in the guide frame 33. The sliding block 32 is fixedly connected with the blanking pipe 31 in the middle. The outer end of the blanking pipe 31 is connected with a concrete mixer. The inner end opening of the blanking pipe 31 is located at the top of the hexagonal die 11.

[0034] As shown in the drawings, Figure 5 and Figure 6 , the compacting mechanism 4 comprises a supporting frame 41, a pneumatic cylinder 42, a pressing frame 43 and a hexagonal plate 44. The supporting frame 41 is fixedly connected to the guide frame 33. The pneumatic cylinder 42 is installed on the supporting frame 41. The pressing frame 43 is connected to the bottom of the pneumatic cylinder 42. The pressing frame 43 is slidingly connected to the supporting frame 41. The hexagonal plate 44 is fixedly connected to the bottom of the pressing frame 43. The number of the hexagonal plates 44 is equal to the number of the hexagonal frames of the hexagonal die 11. The hexagonal plate 44 is slidingly connected in the hexagonal die 11.

[0035] The worker adds sand, cement and water into the mixer in certain proportion, pushes the sliding block 32 to align the discharge pipe 31 with the hexagonal mold 11, and the mixed concrete enters the hexagonal mold 11 through the discharge pipe 31. Then the sliding block 32 is moved to fill the hexagonal mold 11 on the workbench 1 with concrete. Then the mixer is disconnected from the discharge pipe 31, but the mixer keeps stirring to prevent the concrete from solidifying naturally. The cylinder 42 is started, and at this time the discharge pipe 31 has been moved to the end of the guide frame 33. The lower pressing frame 43 and the hexagonal plate 44 are pushed to move downward. After the hexagonal plate 44 contacts the hexagonal mold 11, it continues to move downward by a distance, so that the thickness of the concrete block in the hexagonal mold 11 reaches the predetermined requirement. After the concrete is compacted, the cylinder 42 pulls the lower pressing frame 43 to slide upward to reset. Then the limiting frame 22 is pulled out to the left and right. The sliding limiting frame 22 extrudes the elastic element a24. After the end of the limiting frame 22 leaves the groove of the connecting plate 21, the connecting plate 21 and the buffer frame 14 slide downward under the gravity of the concrete hexagonal block. Then the limiting frame 22 is released. After the elastic element a24 is not extruded, it rebounds and stretches, so that the limiting frame 22 completes the sliding reset on the limiting rod 23. The connecting plate 21 and the buffer frame 14 extrude the buffer spring 13 during the downward sliding process. After being extruded, the buffer spring 13 is slowly compressed to buffer the vertical pressure. The placement plate 16 also descends, and finally the two ends of the placement plate 16 contact the top plate 15 and stop on the top plate 15. A worker pulls out the placement plate 16 from the buffer frame 14. After the placement plate 16 leaves the buffer frame 14, another worker takes the unused placement plate 16 and inserts it into the buffer frame 14. The buffer frame 14 is released. Under the action of the rebound force, the buffer spring 13 resets and stretches, so that the stretching of the buffer spring 13 also makes the buffer frame 14 slide upward to reset. The buffer frame 14 drives the connecting plate 21 to move upward. When the limiting frame 22 passes through the limiting frame 22, the end of the limiting frame 22 extends into the workbench 1, the bottom is beveled, and the upper surface of the connecting plate 21 is curved, so that the limiting frame 22 is extruded and slides to the two sides respectively. When the part of the limiting frame 22 extending into the workbench 1 aligns with the groove of the connecting plate 21, the limiting frame 22 is inserted into the connecting plate 21 under the action of the rebound force of the elastic element a24 to fix it and adjust the position of the placement plate 16 to cooperate with the opening at the top of the workbench 1 to cover all areas at the bottom of the hexagonal mold 11. The worker lifts the removed placement plate 16 to the curing rack. The curing rack can place multiple placement plates 16, thereby saving the space for placing the concrete hexagonal blocks. Moreover, the hexagonal mold 11 is provided with a large gap, which is more convenient and effective for curing the concrete hexagonal blocks.

[0036] As Figure 7 , Figure 9 and Figure 10As shown, it also includes a fixed sleeve 5, a motor 51, a pressing block 511, a vibration frame 52, an elastic element b53, and a connecting rod 54. The fixed sleeve 5 is fixedly connected to the side of the guide frame 33. The motor 51 is installed inside the fixed sleeve 5. The connecting rod 54 is fixedly connected to the lower end of the guide frame 33. The vibration frame 52 is slidably connected between the connecting rods 54. The output shaft of the motor 51 passes through the long plate at the outer end of the vibration frame 52. The pressing block 511 is fixedly connected to the end of the output shaft. The pressing block 511 is slidably connected to the vibration frame 52. The inner end of the vibration frame 52 is a ball rod. An elastic element b53 is sleeved on the ball rod. One end of the elastic element b53 is fixedly connected to the connecting rod 54, and the other end is fixedly connected to the vibration frame 52.

[0037] During the material feeding process, the motor 51 is turned on, and the motor 51 drives the extrusion block 511 to rotate. The extrusion block 511 contacts the vibrating frame 52 and squeezes the vibrating frame 52 to slide forward and backward. When the vibrating frame 52 slides, it pulls the elastic element b53 and disengages from the hexagonal mold 11. When the extrusion block 511 rotates and disengages, the elastic element b53 rebounds, causing the vibrating frame 52 to slide back to its original position. As a result, the ball of the vibrating frame 52 strikes the outer shell of the hexagonal mold 11. The high-speed rotating motor 51 makes the frequency of the vibrating frame 52 striking forward and backward faster, thereby reducing the gap of the concrete in the hexagonal mold 11 before the compaction mechanism 4 works, and making the surface quality of the compacted concrete hexagonal block better. Before turning on the cylinder 42, the motor 51 is turned off. When connecting the mixer and the feeding pipe 31, the motor 51 is turned on.

[0038] like Figures 6-8 As shown, it also includes a transverse scraper 6, a longitudinal scraper 61, an elastic element c62, and a top rod 63. The transverse scraper 6 is fixed to the right side of the feed pipe 31. The longitudinal scraper 61 is slidably connected to the transverse scraper 6. The elastic element c62 is sleeved on the top of the transverse scraper 6. One end of the elastic element c62 is connected to the transverse scraper 6, and the other end is connected to the longitudinal scraper 61. The top rod 63 is fixed to the left end of the support frame 41 and is slidably connected to the longitudinal scraper 61.

[0039] The transverse scraper 6 moves along with the feeding pipe 31. When the concrete is poured, the transverse scraper 6 scrapes the concrete higher than the top surface of the hexagonal mold 11, so that the amount of concrete in each hexagonal frame of the hexagonal mold 11 is kept consistent. After passing through the hexagonal mold 11, the longitudinal scraper 61 is in contact with the top rod 63. The top rod 63 extrudes the longitudinal scraper 61 to slide downward, thereby scraping the surface of the transverse scraper 6, cleaning the concrete adhered to the transverse scraper 6, and compressing the elastic element c62. The scraped concrete falls on the placement plate 16. The worker pushes the sliding block 32 to reset the feeding pipe 31. The transverse scraper 6 moves along with the feeding pipe 31 to scrape the concrete on the hexagonal mold 11 again. Then the concrete is compacted by the compacting mechanism 4. When the transverse scraper 6 moves back to the original position, the longitudinal scraper 61 is separated from the top rod 63. The elastic element c62 rebounds. The longitudinal scraper 61 slides upward to the original position under the action of the rebounding force of the elastic element c62. The fallen concrete is cleaned after the hexagonal concrete block is removed from the placement plate 16.

[0040] As shown in Figure 7 , Figure 9 and Figure 10 , the fixed rod 7, the ladder head rod 71 and the elastic element d72 are further included. The ladder-shaped slot 321 is formed in the top of the sliding block 32. The fixed rod 7 is fixedly connected to the front and rear sides of the support frame 41. The ladder head rod 71 is slidably connected to the fixed rod 7. The bottom of the ladder head rod 71 penetrates through the guide frame 33 and is slidably connected to the ladder-shaped slot 321 of the sliding block 32. The elastic element d72 is sleeved on the ladder head rod 71. One end of the elastic element d72 is fixedly connected to the fixed rod 7, and the other end is fixedly connected to the ladder head rod 71.

[0041] When feeding, the worker pushes the sliding block 32. After the ladder-shaped slot 321 on the sliding block 32 engages with the ladder head rod 71, the feeding pipe 31 and the mixer are connected. In this way, the concrete can be fed into the grooves of the hexagonal mold 11 in alignment, and the concrete can flow quickly and evenly from the middle to the periphery with the cooperation of the vibration frame 52. The concrete will not flow out of the hexagonal mold 11 in large quantities due to the fact that the feeding pipe 31 is located at the edge of the grooves of the hexagonal mold 11. When the sliding block 32 passes through the ladder head rod 71, the sliding block 32 lifts the ladder head rod 71 because the two sides of the ladder head rod 71 are inclined. The sliding ladder head rod 71 compresses the elastic element d72. When the ladder-shaped slot 321 of the sliding block 32 is aligned with the ladder head rod 71, the elastic element d72 pushes the ladder head rod 71 to engage with the sliding block 32, thereby completing the positioning. When the sliding block 32 is pushed again, the ladder head rod 71 is also extruded to slide.

[0042] The prefabricated phosphogypsum concrete pouring and molding mold forming method comprises the following steps:

[0043] Firstly, sand, cement and water are added into a mixing container in a certain proportion for mixing.

[0044] Secondly, the mixed concrete is poured into the hexagonal mold 11 through the discharging pipe 31;

[0045] Then, the concrete in the hexagonal mold 11 is flattened and compacted by using the compacting mechanism 4, and the concrete hexagonal block is obtained;

[0046] Finally, the fixing of the buffer frame 14 by the limiting assembly 2 is released, the formed concrete hexagonal block drives the buffer frame 14 to descend, the buffer spring 13 is compressed, the staff member removes the placement plate 16 on which the concrete hexagonal block is placed, and waits for the concrete hexagonal block to solidify and form.
