Description

Technical Field

[0001] This invention relates to the field of hardening molding technology, and in particular to a hardening molding device for the production of concrete pipe piles. Background Technology

[0002] With the development of reform and opening up and economic construction, prestressed concrete pipe piles using the pre-tensioning method have begun to be widely used in railway systems and have expanded to industrial and civil buildings, municipal works, metallurgy, ports, highways and other fields. In the delta and Pearl River Delta regions, due to the geological conditions suitable for the use of pipe piles, the demand for pipe piles has surged, thus rapidly forming a new industry. Concrete is a commonly used material in construction engineering, and its strength and durability depend on the quality of concrete hardening. The concrete hardening treatment method is a key step that has an important impact on the service life and performance of concrete.

[0003] A search revealed Chinese invention patent publication number CN119347948B, which discloses a concrete pipe pile hardening and molding device. The device includes a horizontally placed tank and an end cap at the tank opening. A steam generator connected to the tank's interior is located at the end of the tank away from the end cap. The hardening and molding device is controlled by a controller. A motor is located at the end of the tank's interior away from the end cap. The motor's output shaft is fixedly connected to a drive gear. A perforated plate is provided on the inner wall of the tank. A molding cylinder is inserted into and rotatably connected to a hole in the perforated plate. The opening of the molding cylinder faces the end cap. This invention places a mold containing concrete into the molding cylinder within the tank, allowing the concrete inside the molding cylinder to undergo steam curing during centrifugal molding. This avoids loosening of the concrete inside the mold during entry into the tank and saves on concrete pipe pile processing steps, thus improving both the quality and efficiency of the concrete pipe piles.

[0004] Existing equipment requires customization for single-size molds, and changing specifications is time-consuming and labor-intensive. When the centrifuge rotates at high speed, the mold interface is prone to gaps due to vibration, resulting in grout / steam leakage. Concrete molds weigh hundreds of kilograms, and manual handling can easily cause workplace accidents. In addition, traditional curing methods can lead to localized accumulation of steam condensate, resulting in powdering and strength delamination on the concrete surface.

[0005] Therefore, the existing hardening and molding device for producing concrete pipe piles cannot meet the needs of actual use, so there is an urgent need for improved technology in the market to solve the above problems. Summary of the Invention

[0017] The present invention has the following beneficial effects: 1. This invention utilizes a support structure mounted on a base plate to install and place the curing structure during use. A lifting mechanism then elevates the installation structure using a rotating shaft as a fulcrum, allowing the mold to naturally tilt to 45 degrees. Operators can easily unload the material by simply pushing the hook, reducing labor intensity by 60% and eliminating the risks associated with heavy object handling. Through the curing structure on the support plate, steam is generated by the steam generator in the water tank within the curing structure. Steam enters the inner cavity of the molding barrel through a connecting valve, steam pipe, and limiting block. The sealing plate magnetically connects with the installation pipe and the molding barrel, ensuring stable steam retention. Combined with the rotation of the centrifugal mold, this ensures uniform heating and humidification of all parts of the pipe pile, accelerating the cement hydration reaction and reducing defects such as cracks and insufficient strength. The installation of the curing structure... The structure, in use, involves the installation and placement of fixed and rotating structures. The mounting structure and placement holes are made of high-strength alloy casting, ensuring deformation of less than 0.1mm under centrifugal loads and maintaining dynamic balance during high-speed rotation. The placement holes allow for batch installation of centrifugal molds. The fixed structure on the mounting frame, driven by a spring-loaded telescopic rod, slides the sliders and, in conjunction with a positioning rotating rod, dynamically clamps centrifugal molds of different sizes. The elastic deformation capability of the springs allows the device to be compatible with various mold specifications, eliminating the need for frequent equipment changes and reducing production costs. Furthermore, the telescopic characteristics of the springs and spring-loaded telescopic rods between the sliders allow for flexible adjustment of the spacing of the positioning rotating rod, ensuring stable clamping and positioning of centrifugal molds of different sizes. The same device can adapt to the installation needs of various sizes of forming barrels without significant modifications, reducing the cost of purchasing specialized equipment and improving the overall utilization rate of the equipment.

[0018] 2. This invention utilizes a rotating structure mounted on the installation structure. During use, a centrifugal motor drives the mold to rotate at high speed. Under centrifugal force, the concrete is evenly distributed on the inner wall of the mold, forming a dense, hollow tubular structure, thus improving the compressive strength of the pipe pile. Simultaneously, the steam curing system directly supplies steam into the rotating mold through steam pipes, achieving simultaneous centrifugal molding and steam curing, significantly shortening the hardening time. Furthermore, by driving the centrifugal mold to rotate synchronously, the centrifugal force causes the concrete to converge towards the inner wall of the forming barrel, precisely forming a hollow tubular structure, avoiding problems such as uneven wall thickness and irregular shape. At the same time, it removes internal air bubbles, improving the density of the pipe pile. Through the sealing structure on the rotating structure, the sealing plate adheres to the end face of the installation pipe and the forming barrel through rotation, combined with magnetic connection technology, ensuring no leakage during high-speed centrifugation and steam curing, improving process reliability. Through the centrifugal mold on the installation structure, the locking structure of the limiting block and limiting groove combined with the magnetic sealing plate simplifies the mold installation and disassembly process, shortening the production cycle. Furthermore, the limiting block ensures that steam is evenly distributed into the forming barrel, avoiding cracks or uneven strength caused by local temperature differences. To ensure product consistency, steam enters the mold through the distributed nozzles of the limiting block. Combined with the turbulence effect generated by rotation, this ensures that the temperature difference between different parts of the concrete is ≤2℃, effectively inhibiting crack formation and achieving a finished product qualification rate of over 98%. The rotating structure features an adjustable mechanism. During use, the lifting plate connects to the lifting structure, and the adjusting rod and frame support the installation structure in conjunction with the lifting structure. The lifting structure's rotation is achieved through the adjustment of the lifting mechanism and the adjusting rod and installation block. The relative rotation of connecting rod one and connecting rod two is achieved by adjusting the spacing of the adjusting rods, thus raising and lowering the adjustable structure. Furthermore, the extension and retraction of the lifting structure, in conjunction with the adjusting mechanism, achieves the rotation of the installation structure. The lifting drive structure on the base plate drives the rotating rod through its lifting motor, causing the two adjusting rods to move away from each other. The sealing structure and centrifugal motor tilt upwards around the rotating shaft, and the sealing plate can be opened by rotating in the opposite direction. Workers can easily remove the centrifugal mold and formed pipe piles using hooks, reducing labor intensity.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0024] Please see Figure 1-8 As shown, this embodiment is a hardening and forming device for producing concrete pipe piles, including a base plate 1, a support structure 2 fixedly connected to the left side of the upper end face of the base plate 1, a curing structure 3 provided on one side of the support structure 2, an installation structure 4 fixedly connected to one side of the curing structure 3, and a fixing structure 5 evenly arranged in the inner cavity of the installation structure 4. A rotating structure 6 is rotatably connected to the inner cavity of the mounting structure 4 near the support structure 2. A centrifugal mold 7 is placed in the inner cavity of the fixed structure 5. An adjusting structure 8 is provided on the side of the rotating structure 6 away from the support structure 2. A lifting structure 9 is provided in the inner cavity of the adjusting structure 8. A lifting drive structure 10 is provided on the upper surface of the base plate 1 in the middle of the lifting structure 9.

[0025] Furthermore, the support structure 2 includes a support frame 21 fixedly connected to the left side of the upper end face of the base plate 1. A rotating shaft 22 is rotatably connected to the upper part of the inner cavity of the support frame 21. Connecting blocks 23 are evenly fixedly connected to the outer surface of the rotating shaft 22. A maintenance structure 3 is fixedly connected to the right end face of the connecting block 23. The maintenance structure 3 is installed and placed during use through the support structure 2 on the base plate 1. Then, the installation structure 4 is lifted by the lifting mechanism with the rotating shaft 22 as the fulcrum, so that the mold naturally tilts to 45 degrees. The operator only needs to push the hook lightly to unload the material, reducing the labor intensity by 60% and eliminating the risk of heavy object handling.

[0026] Furthermore, the curing structure 3 includes a water tank 31 fixedly connected to the right end face of the connecting block 23. A connecting valve 32 is fixedly connected to the middle of the right end face of the water tank 31. A steam pipe 33 is evenly fixedly connected to the outer surface of the connecting valve 32. The right end face of the water tank 31 is fixedly connected to the installation structure 4 through a bracket. The end of the steam pipe 33 away from the connecting valve 32 passes through the installation structure 4. A steam generator is fixedly connected to the side of the inner cavity of the water tank 31 near the connecting valve 32. Through the curing structure 3 on the support structure 2, after the steam generator in the water tank 31 in the curing structure 3 is started during use, steam enters the inner cavity of the molding barrel 71 through the connecting valve 32, the steam pipe 33 and the limiting block 72. The sealing plate 642 is magnetically connected to the installation pipe 42 and the molding barrel 71 to ensure stable steam retention. With the rotation of the centrifugal mold 7, the various parts of the pipe pile are heated and moistened evenly, which accelerates the cement hydration reaction and reduces defects such as cracks and insufficient strength.

[0027] Furthermore, the installation structure 4 includes an installation plate 41 fixedly connected to the right end face of the water tank 31. An installation pipe 42 is fixedly connected to the right end face of the installation plate 41. A perforated plate 43 is evenly fixedly connected to the inner cavity of the installation pipe 42. Placement holes 44 are evenly opened on the right end face of the perforated plate 43. The end of the steam pipe 33 away from the connecting valve 32 passes through the installation plate 41 and is fixedly connected. A fixing structure 5 is provided in the inner cavity of the placement hole 44. Through the installation structure 4 on the maintenance structure 3, the fixing structure 5 and the rotating structure 6 are installed and placed during use. Furthermore, the installation structure 4 and the placement hole 44 are made of high-strength alloy casting, and the deformation is <0.1mm when bearing centrifugal load, ensuring dynamic balance under high-speed rotation. At the same time, the centrifugal mold 7 can be installed and placed in batches through the placement hole 44.

[0028] Furthermore, the fixing structure 5 includes symmetrically formed grooves 51 along the centerline on the inner wall of the placement hole 44. Slider 52s are symmetrically slidably connected to the inner cavity of the grooves 51. A spring telescopic rod 53 is fixedly connected to one end of the slider 52 away from the orifice plate 43. A positioning rotating rod 54 is fixedly connected between two spring telescopic rods 53 via a universal joint. An adjusting spring is fixedly connected between two adjacent sliders 52, and the adjusting spring is movably sleeved within the inner cavity of the groove 51. Through the fixing structure 5 on the mounting structure 4, the sliders 52 are driven to slide by the spring telescopic rods 53 during use. This, combined with the positioning rotating rod 54, enables dynamic clamping of centrifugal molds 7 of different sizes. The elastic deformation capability of the springs allows the device to be compatible with various mold specifications, eliminating the need for frequent equipment changes and reducing production costs. Furthermore, the telescopic characteristics of the springs and spring telescopic rods 53 between the sliders 52 drive the positioning rotating rod 54 to flexibly adjust the spacing, allowing for stable clamping and positioning of centrifugal molds 7 of different sizes. The same device can adapt to the installation requirements of various sizes of forming barrels 71 without significant modifications, reducing the cost of purchasing specialized equipment and improving the overall utilization rate of the equipment.

[0029] Furthermore, the rotating structure 6 includes a driven wheel 61 that rotates uniformly around the center point and is connected to the right end face of the mounting plate 41. A limiting groove 62 matching the centrifugal mold 7 is provided in the middle of the right end face of the driven wheel 61. A driving wheel 63 is rotatably connected to the middle of the right end face of the mounting plate 41. The driven wheel 61 and the driving wheel 63 mesh with each other. A drive shaft is fixedly connected to the right end face of the driving wheel 63. Through the rotating structure 6 on the mounting structure 4, the mold is driven to rotate at high speed by the centrifugal motor 65 during use. Under the action of centrifugal force, the concrete is evenly distributed on the inner wall of the mold, forming a dense hollow tubular structure, which improves the compressive strength of the pipe pile. At the same time, the steam curing system 3 directly delivers steam into the rotating mold through the steam pipe 33, realizing the simultaneous centrifugal molding and steam curing, which greatly shortens the hardening time. Then, by driving the centrifugal mold 7 to rotate synchronously, the centrifugal force causes the concrete to converge towards the inner wall of the molding bucket 71, accurately forming a hollow tubular structure, avoiding problems such as uneven wall thickness and irregular shape, and at the same time, expelling internal air bubbles, which improves the density of the pipe pile.

[0030] Furthermore, the drive shaft passes through the perforated plate 43 and is rotatably connected. A sealing structure 64 is rotatably connected to the right end face of the drive shaft. A centrifugal motor 65 is installed on the right end face of the sealing structure 64. The sealing structure 64 includes a mounting block 641 rotatably connected to the right end face of the drive shaft. A sealing plate 642 is hinged to the side end face of the mounting block 641. The output end of the centrifugal motor 65 passes through the mounting block 641 and is fixedly connected to the drive shaft. Through the sealing structure 64 on the rotating structure 6, the sealing plate 642 is rotated and fits against the end face of the mounting tube 42 and the forming barrel 71 during use. Combined with magnetic connection technology, this ensures no leakage during high-speed centrifugation and steam curing, and improves process reliability. Centrifugal mold 7 includes a forming barrel 71 placed between two opposing positioning rotating rods 54. A limiting block 72 is fixedly connected to the left end face of the forming barrel 71. The limiting block 72 matches the inner cavity of the limiting groove 62. A connecting groove 73 is opened on the left end face of the limiting block 72. One end of the steam pipe 33 passes through the driven wheel 61 and is sleeved in the inner cavity of the connecting groove 73. The inner cavity of the steam pipe 33 is interconnected with the inner cavity of the forming barrel 71 through the connecting groove 73. The sealing plate 642 is magnetically connected to the forming barrel 71 and the mounting pipe 42. Through the centrifugal mold 7 on the mounting structure 4, During use, the snap-fit ​​structure of the limiting block 72 and the limiting groove 62, combined with the magnetic sealing plate 642, simplifies the mold installation and disassembly process, shortens the production cycle, and ensures that steam is evenly distributed into the molding barrel 71 through the limiting block 72, avoiding cracks or uneven strength caused by local temperature differences and ensuring product consistency. Since the steam enters the mold through the distributed nozzles of the limiting block 72, combined with the turbulence effect generated by the rotation, it ensures that the temperature difference of each part of the concrete is ≤2℃, effectively inhibiting the formation of cracks, and the finished product qualification rate reaches more than 98%.

[0031] Furthermore, the adjustment structure 8 includes an adjustment rod 81 rotatably connected to the front and rear end faces of the mounting block 641. An adjustment frame 82 is fixedly connected to the end of the adjustment rod 81 away from the mounting block 641. A lifting plate 83 is fixedly connected to the right end face of the two adjustment frames 82. A lifting groove is symmetrically opened on the upper end face of the lifting plate 83. A lifting structure 9 is provided in the inner cavity of the lifting groove. The lifting plate 83 is fixedly connected to the centrifugal motor 65. Through the adjustment structure 8 on the rotating structure 6, the lifting structure 9 is connected and installed through the lifting plate 83 during use. Then, the mounting structure 4 is supported by the adjustment rod 81 and the adjustment frame 82 in cooperation with the lifting structure 9. Furthermore, the rotation of the mounting structure 4 is achieved by the lifting of the lifting structure 9 in cooperation with the adjustment rod 81 and the mounting block 641.

[0032] Furthermore, the lifting structure 9 includes a connecting rod 91 rotatably connected to the inner cavity of the lifting groove. An adjusting connecting rod 92 is rotatably connected to the lower part of the inner cavity of the connecting rod 91. A connecting rod 93 is rotatably connected to the lower part of the outer surface of the adjusting connecting rod 92. The lower part of the inner cavity of the connecting rod 93 is rotatably connected to the base plate 1 through a bracket. A lifting drive structure 10 is provided between the two adjusting connecting rods 92. By adjusting the distance between the adjusting connecting rods 92 through the lifting structure 9 on the adjusting structure 8, the relative rotation of the connecting rod 91 and the connecting rod 93 is realized, thus realizing the lifting of the adjusting structure 8. Furthermore, by extending and retracting the lifting structure 9, the rotation of the mounting structure 4 is realized with the cooperation of the adjusting structure 8.

[0033] Furthermore, the lifting drive structure 10 includes a telescopic sleeve 101 symmetrically fixedly connected to the upper end face of the base plate 1. The telescopic sleeve 101 is located on both sides of the connecting rod 93. The inner cavity of the telescopic sleeve 101 is slidably connected to a telescopic inner rod 102. A rotating rod 103 is rotatably connected between the two telescopic inner rods 102. The rotating rod 103 passes through the adjusting connecting rod 92 and is threaded. Two sections of threads in opposite directions are symmetrically opened on the outer surface of the rotating rod 103. A lifting motor 104 is fixedly connected to the upper part of the rear end face of the rotating rod 103. The output end of the lifting motor 104 passes through the telescopic inner rod 102 and is fixedly connected to the rear end of the rotating rod 103. Through the lifting drive structure 10 on the base plate 1, the lifting motor 104 of the lifting drive structure 10 drives the rotating rod 103 to rotate, so that the two adjusting connecting rods 92 move away from each other. The sealing structure 64 and the centrifugal motor 65 are tilted upward with the rotating shaft 22 as the center. The sealing plate 642 can be opened by rotating in the opposite direction. The workers can easily take out the centrifugal mold 7 and the formed pipe pile with the help of the hook, reducing the labor intensity.

[0034] Working principle: During the operation, the concrete is first mixed and prepared. Then, as needed, the workers weave the reinforcing cage and place it into the inner cavity of centrifugal molds 7 of different sizes. Finally, the concrete slurry is injected into the inner cavity of the molding bucket 71. At this time, pulling the sealing plate 642 causes it to rotate, thus inserting the centrifugal mold 7 into the inner cavity of the placement hole 44. This causes the limiting block 72 to engage with the limiting groove 62, allowing the steam pipe 33 to pass through the limiting block 72. Since the inner cavity of the placement hole 44 is equipped with a fixing structure 5, when the centrifugal mold 7 is placed between the fixing structures 5, the positioning rotating rod 54 moves away from each other. Therefore, the spring telescopic rod 53 extends and retracts, causing the sliders 52 to slide relative to each other. Thus, the springs between the two sliders 52 extend and retract. Through the extension and retraction of the springs between the sliders 52 and the spring telescopic rod 53, the positioning rotating rod 54 can clamp and position centrifugal molds 7 of different sizes. This allows centrifugal molds 7 of different sizes to be placed in the inner cavity of the placement hole 44. At this time, rotating the sealing plate 642 in the opposite direction causes the sealing plate 642 to fit against the mounting pipe 42 and the right end face of the forming barrel 71. At the same time, since the forming barrel 71, the mounting pipe 42, and the sealing plate 642 are magnetically connected, a stable seal is achieved for the inner cavity of the forming barrel 71. Then, the centrifugal motor 65 is started, causing its output end to rotate. This rotates the drive shaft, which in turn causes the drive wheel 63 to rotate. Since the drive wheel 63 meshes with the driven wheel 61, the driven wheel 61 rotates. At this time, because the centrifugal mold 7 is engaged with the limiting groove 62 on the driven wheel 61 via the limiting block 72, all centrifugal molds 7 connected to the driven wheel 61 rotate. When the molding barrel 71 rotates, the rotation of the centrifugal mold 7 causes the concrete inside to generate centrifugal force, causing the concrete in the centrifugal mold 7 to converge towards the inner wall of the mold, thus forming a hollow tubular shape. Activating the curing structure 3 starts the steam generator inside the water tank 31, which in turn activates the connecting valve 32. Steam then enters the inner cavity of the molding barrel 71 through the connecting valve 32, steam pipe 33, and limiting block 72. The steam then cures the concrete inside the molding barrel 71 via the limiting block 72. Simultaneously, the centrifugally molded concrete inside the molding barrel 71 hardens over time. This is because the concrete inside the mold undergoes curing during the centrifugal molding process. After the centrifugal molding of the concrete pipe pile is completed, the lifting drive structure 10 is activated, causing the output end of the lifting motor 104 to rotate. As a result, the rotating rod 103 rotates, and the two adjusting connecting rods 92 move away from each other. Therefore, the sealing structure 64 and the centrifugal motor 65 rotate upward around the rotating shaft 22, thus achieving the upward tilting of the installation structure 4 and the centrifugal mold 7. At this time, the sealing plate 642 is pulled, causing the sealing plate 642 to rotate in the opposite direction, thereby opening the sealing plate 642.
