Description

Technical Field

[0001] This invention relates to the field of casting technology, specifically to a method and apparatus for casting large-volume box culverts. Background Technology

[0002] During the construction of the box culvert, the soil, due to the infiltration and erosion of water on both sides, formed a typical coastal silty clay layer. Survey data shows that this ultra-deep silty clay layer reaches a depth of 15m to 20m. This soil layer itself is characterized by low strength, high compressibility, high water content, and high porosity. Furthermore, the construction period coincides with the flood season, increasing groundwater and surface water levels, significantly increasing the difficulty and risk of the project. Improper handling could lead to quality problems, and in severe cases, even safety accidents. Current construction techniques typically treat the silty foundation of the box culvert by solidifying the silt. After consolidation and settlement stabilization, the foundation pit is excavated for culvert construction. This method often suffers from high costs, difficulty in quality control, and a long construction period. Summary of the Invention

[0003] The purpose of this invention is to provide a method and apparatus for casting large-volume box culverts to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A large-volume box culvert casting device includes an outer shell, a partition A mounted on the outer shell, grinding mechanisms mounted on both sides of the partition A, a positioning mechanism mounted on the upper side of the partition A, an intermediate support mounted on one side of the positioning mechanism for storing the box culvert, a vibration mechanism mounted inside the box culvert, a partition B mounted above the box culvert, mixing mechanisms mounted on both sides of the partition B, a pressurizing mechanism mounted on the upper side of the mixing mechanism, the positioning mechanism positioning the box culvert, the vibration mechanism vibrating the cast box culvert, the mixing mechanism mixing the concrete, and the pressurizing mechanism pressurizing and spraying water.

[0005] The positioning mechanism includes a drive motor, which is mounted on the partition A. A cam is mounted on one side of the output shaft of the drive motor, and a first gear is mounted on the other side of the output shaft of the drive motor. A transmission belt A meshes with the outer side of the first gear. A follower is mounted on one side of the cam, and a fixed block B is mounted on one side of the follower. A grinding wheel is rotatably mounted on the fixed block B. The follower is mounted on one end of the grinding wheel. The grinding wheel has an annular groove, and a guide shaft A is mounted in the annular groove. A return spring A is mounted on the guide shaft A. The grinding wheel has an internal electric roller structure.

[0006] The drive motor drives the cam to rotate. When the cam enters the push stroke, the cam pushes the follower to move and stretches the return spring A. The follower drives the grinding wheel to contact the side of the box culvert. At this time, the grinding wheel rotates and grinds the side of the box culvert. When the cam completes the push stroke, the return spring A is released. The return spring A pushes the grinding wheel to move in the opposite direction and move the grinding wheel away from the box culvert. Through the above design, the side of the box culvert can be ground to reduce surface deposits and improve the service life of the box culvert.

[0007] The intermediate support is installed on the partition B. Rectangular through slots are provided on both sides of the intermediate support. A side template is installed in the rectangular through slot on one side of the intermediate support, and a top template is installed in the rectangular through slot on the upper side of the intermediate support. The positioning mechanism includes an adjusting motor, on the output shaft of which a bevel gear set is mounted. The bevel gear set consists of a first bevel gear and a second bevel gear, which mesh perpendicularly and alternately. The first bevel gear is mounted on the output shaft of the adjusting motor, and an adjusting shaft B is mounted in the middle of the second bevel gear. Both ends of the adjusting shaft B are rotatably mounted on the outer casing. An adjusting plate B is mounted on the adjusting shaft B, and a connecting piece B is rotatably connected to the adjusting plate B. One side of the connecting piece B is mounted on the upper side of the side template. An adjusting plate A is mounted below the adjusting plate B, and a connecting piece A is rotatably mounted on the adjusting plate A. One side of the connecting piece A is mounted on the lower side of the side template. An adjusting shaft A is mounted in the middle of the adjusting plate A, and both sides of the adjusting shaft A are mounted on the outer casing. The adjusting shaft B and the adjusting plate B are threaded together. The adjusting motor drives the first bevel gear in the bevel gear set to rotate, the first bevel gear drives the second bevel gear to rotate, the second bevel gear drives the adjusting shaft B to rotate, the adjusting shaft B drives the adjusting plate B to move, the adjusting plate B drives the connecting piece B to move, and the connecting piece B drives the side formwork to rotate. The side formwork will rotate along one side of the connecting piece A. After the box culvert is poured, the adjusting motor drives the side formwork to rotate at a certain angle so that the side formwork does not contact the box culvert, which is convenient for the next box culvert pouring.

[0008] A top mold push rod is installed on the outer shell. The top mold push rod is an electric push rod. A top template is installed on the output shaft of the top mold push rod. A guide shaft B is installed on one side of the top template. The guide shaft B is slidably connected to the top template. One side of the guide shaft B is installed on the outer shell, and the other side of the guide shaft B is installed on the top template. A connecting rod assembly is installed on the top template. The connecting rod assembly consists of a first connecting rod and a second connecting rod. The first connecting rod and the second connecting rod are rotatably connected. One side of the connecting rod assembly is rotatably installed on the outer shell.

[0009] The top formwork push rod drives the top formwork to move upward. The top formwork moves upward along the guide shaft B. The first connecting rod and the second connecting rod cross to support the movement of the side formwork, ensuring the stability of the top formwork and preventing the side formwork from contacting the upper side of the box culvert, which facilitates the next pouring of the box culvert.

[0010] The vibration mechanism includes a vibration motor, an inner mold mounted on the lower side of the vibration motor, the vibration motor mounted on the inner mold, a bevel gear A mounted on one side of the output shaft of the vibration motor, a bevel gear C mounted on the other side of the output shaft of the vibration motor, a bevel gear B meshing on one side of the bevel gear C, a bevel gear D meshing on the other side of the bevel gear C, bevel gear A meshing with bevel gear B and bevel gear D respectively, a drive shaft mounted in the middle of the bevel gear D, the drive shaft being rotatably mounted on the inner mold, a vibrating plate mounted on one side of the drive shaft, the inner mold being installed inside a box duct, vibration grooves being provided on both sides of the inner mold, the vibrating plate being installed in the vibration grooves, bevel gear A and bevel gear C being incomplete gears, bevel gear A meshing alternately with bevel gear B and bevel gear D respectively, and bevel gear C meshing alternately with bevel gear B and bevel gear D respectively.

[0011] The vibratory motor drives bevel gears A and C to rotate. Since bevel gears A and C are incomplete gears, and bevel gear A meshes with bevel gears B and D alternately, while bevel gear C meshes with bevel gears B and D alternately, bevel gear A first meshes with bevel gear D, driving bevel gear D to rotate in the forward direction. Then bevel gear C meshes with bevel gear D, driving bevel gear D to rotate in the reverse direction. The transmission process for bevel gear B is the same as described above. Through this design, bevel gears D and B continuously rotate in both directions, driving the vibrating plate to continuously rotate in both directions. During the rotation, the vibrating plate generates high-speed vibration, which can vibrate the box culvert during casting, reducing internal air and improving the quality of the box culvert.

[0012] The mixing mechanism includes a mixing tank with a first inlet on one side and a first outlet on the other side. The mixing tank is mounted on a partition B. A mixing motor is mounted in the middle of the mixing tank. A pressurizing mechanism is mounted on the upper side of the output shaft of the mixing motor. A drive disc A is mounted on the output shaft of the mixing motor, and a pawl A is mounted on the drive disc A. A mixing plate is mounted on the outer side of the drive disc A. The lower side of the mixing plate is mounted on the output shaft of the mixing motor via a bearing. A ratchet tooth is provided on the upper side of the mixing plate. Electromagnet assemblies are mounted on both sides of the mixing plate. Each electromagnet assembly consists of a first electromagnet and a protective shell. The first electromagnet is mounted on the protective shell, and the protective shell is mounted on the mixing plate. A mixing rope is mounted on the telescopic rod of the first electromagnet. A rotating component A is mounted on the output shaft of the mixing motor. A mixing rod is rotatably connected to the rotating component A. The mixing rope is connected to one side of the mixing rod. A mixing blade is mounted on the mixing rod, and the longitudinal section of the mixing blade is "C".

[0013] The mixing motor drives the drive disc A to rotate forward, and the pawl A engages with the mixing plate. The drive disc A drives the mixing plate to rotate synchronously. At the same time, the output shaft of the mixing motor drives the rotating component A to rotate, which in turn drives the mixing rod to rotate. The mixing rod drives the mixing blades to rotate, and the mixing blades mix the concrete in the mixing bucket to prevent the concrete from losing its activity. When it is necessary to adjust the angle of the mixing rod, the electromagnet assembly on the mixing plate is attracted. The telescopic rod on the electromagnet assembly drives the mixing rope to move, and the mixing rope drives the mixing rod to rotate. The mixing rod causes the angle of the mixing blades to deflect, which can fully mix the concrete.

[0014] The pressurizing mechanism includes blades. A drive disc B is mounted on the output shaft of the stirring motor. A pawl B is rotatably mounted on the drive disc B. A rotating component B is mounted on the outer side of the drive disc B. A ratchet tooth is provided on the lower middle side of the rotating component B. The upper middle side of the rotating component B is mounted on the output shaft of the stirring motor via a bearing. Blades are mounted on the outer side of the rotating component B. A tank is mounted on the outer side of the blades. The tank and the output shaft of the stirring motor are eccentrically mounted. A second inlet is provided on one side of the tank. A second outlet is provided on the other side of the tank. The second outlet is connected to the top template via a pipe.

[0015] The output shaft of the stirring motor drives the active disc B to rotate in the opposite direction. The pawl B engages with the rotating component B. The active disc B drives the rotating component B to rotate in the opposite direction. The rotating component B drives the blades to rotate. When the liquid enters the tank from the second inlet, the rotation of the blades will generate centrifugal force, which will increase the liquid pressure. The pressurized liquid will be transported to the box culvert through the pipeline to maintain and reduce dust in the box culvert, thereby improving the service life of the box culvert.

[0016] The pawls A and B are mirror images of each other, the electromagnet assembly is installed in reverse, a pressure sensor is installed inside the grinding wheel, the pressure sensor is electrically connected to the control system, and a fixing block A is installed on the outer casing.

Based on steps S401 and S601, the following processing is performed: The road roller performs overall vibratory compaction on the graded crushed stone subbase, compacting it to a degree of compaction between 94% and 98%.

[0020] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. Equipped with a vibration mechanism, requiring no external equipment. Bevel gears D and B continuously rotate in both directions, driving the vibrating disc to do the same. During this rotation, the vibrating disc generates high-speed vibration, which can vibrate the box culvert during pouring, reducing internal air and improving its quality.

[0021] 2. Integrated design of pressurization and mixing mechanisms. The mixing motor drives the mixing mechanism in the forward direction and the pressurization mechanism in the reverse direction. The output shaft of the mixing motor drives the active disc B to rotate in the opposite direction. The pawl B engages with the rotating component B, and the active disc B drives the rotating component B to rotate in the opposite direction. The rotating component B drives the blades to rotate. When liquid enters the tank through the second inlet, the rotation of the blades generates centrifugal force, increasing the liquid pressure. The pressurized liquid is then transported through pipelines to the box culvert for maintenance and dust suppression, extending the service life of the box culvert. The mixing blades mix the concrete in the mixing tank, preventing the concrete from losing its activity. When the angle of the mixing rod needs to be adjusted, the electromagnet assembly on the mixing plate engages. The telescopic rod on the electromagnet assembly moves the mixing rope, which in turn rotates the mixing rod. The mixing rod causes the angle of the mixing blades to deflect, ensuring thorough mixing of the concrete.

[0022] 3. Automatic formwork positioning and detachment facilitates pouring. The top formwork push rod moves the top formwork upwards along guide shaft B. The first and second connecting rods cross and support the movement of the side formwork, ensuring the stability of the top formwork and preventing it from contacting the upper side of the box culvert, facilitating the next pouring of the box culvert. The adjusting plate B moves the connecting piece B, which in turn rotates the side formwork. The side formwork rotates along one side of the connecting piece A. After the box culvert is poured, the adjusting motor rotates the side formwork by a certain angle, preventing it from contacting the box culvert and facilitating the next pouring of the box culvert.

[0036] The mixing motor 61 drives the drive disc A68 to rotate forward, and the pawl A69 engages with the mixing plate 63. The drive disc A68 drives the mixing plate 63 to rotate synchronously. At the same time, the output shaft of the mixing motor 61 drives the rotating component A67 to rotate, which in turn drives the mixing rod 65 to rotate. The mixing rod 65 drives the mixing blade 66 to rotate, and the mixing blade 66 mixes the concrete in the mixing bucket 6 to prevent the concrete from losing its activity. When it is necessary to adjust the angle of the mixing rod 65, the electromagnet assembly 63 on the mixing plate 63 is attracted.

[0042] Working principle of the invention: Press the start button on control panel 1 to start the device. Use a crane to lift the device through fixing block A12 and bring the bottom of the device into contact with the bottom surface to be poured. At the same time, treat the bottom surface in contact according to the steps mentioned in the treatment method.

[0043] When the box culvert 13 needs to be positioned before pouring, the side formwork 5 or the top formwork 51 needs to be adjusted to the corresponding position. The specific work is as follows: The adjusting motor 36 drives the first bevel gear in the bevel gear set 37 to rotate, the first bevel gear drives the second bevel gear to rotate, the second bevel gear drives the adjusting shaft B33 to rotate, the adjusting shaft B33 drives the adjusting plate B31 to move, the adjusting plate B31 drives the connecting piece B35 to move, and the connecting piece B35 drives the side formwork 5 to rotate. The side formwork 5 will rotate along one side of the connecting piece A34. After the box culvert 13 is poured, the adjusting motor 36 drives the side formwork 5 to rotate a certain angle so that the side formwork 5 does not contact the box culvert 13, which is convenient for the next pouring of the box culvert 13. The top formwork push rod 54 drives the top formwork 51 to move upward. The top formwork 51 moves upward along the guide shaft B53. The first connecting rod and the second connecting rod cross support the movement of the side formwork 51 to ensure the stability of the top formwork 51, so that the side formwork 51 does not contact the upper side of the box culvert 13, which is convenient for the next pouring of the box culvert 13.

[0044] When the concrete is poured to the hollow position of the box culvert 13, the workers place the inner mold 48 to shape the hollow position of the box culvert 13. At the same time, the vibration mechanism inside the inner mold 48 can perform vibration. The specific working process is as follows: the vibration motor 4 drives the bevel gears A41 and C43 to rotate. Since the bevel gears A41 and C43 are incomplete gears, and bevel gear A41 meshes with bevel gears B42 and D44 alternately, and bevel gear C43 meshes with bevel gears B42 and D44 alternately, bevel gear A41 first meshes with bevel gear D44. When meshing, bevel gear A41 drives bevel gear D44 to rotate in the forward direction. Then, bevel gear C43 meshes with bevel gear D44, and bevel gear C43 drives bevel gear D44 to rotate in the reverse direction. The transmission process of bevel gear B42 is the same as described above. Through the above design, bevel gears D44 and B42 continuously rotate in both directions. Bevel gears D44 and B42 drive vibrating plate 46 to continuously rotate in both directions. During the forward and reverse rotation, vibrating plate 46 generates high-speed vibration. When pouring the box culvert 13, it can vibrate the box culvert 13, reduce internal air, and improve the quality of box culvert 13.

[0045] After the box culvert 13 is completely poured, the two sides can be ground or sprayed with water for maintenance. When grinding is selected, the specific working process is as follows: the drive motor 2 drives the cam 22 to rotate. When the cam 22 enters the push stroke, the cam 22 pushes the follower 23 to move and stretches the return spring A25. The follower 23 drives the grinding wheel 24 to contact the side of the box culvert 13. At this time, the grinding wheel 24 rotates and grinds the side of the box culvert 13. When the cam 22 completes the push stroke, the return spring A25 is released. The return spring A25 pushes the grinding wheel 24 to move in the opposite direction and move the grinding wheel 24 away from the box culvert 13. Through the above design, the side of the box culvert 13 can be ground to reduce surface deposits and improve the service life of the box culvert 13. When water spray maintenance is selected, the specific working process is as follows: The output shaft of the stirring motor 61 drives the active disc B73 to rotate in the opposite direction. The pawl B74 engages with the rotating part B72. The active disc B73 drives the rotating part B72 to rotate in the opposite direction. The rotating part B72 drives the blade 71 to rotate. When the liquid enters the tank 7 from the second inlet, the rotation of the blade 71 will generate centrifugal force, which will increase the liquid pressure. The pressurized liquid will be transported to the box culvert 13 through the pipeline to maintain and reduce dust in the box culvert 13, thereby improving the service life of the box culvert 13.

[0046] During the above process, the concrete during pouring is mixed by a mixing mechanism. The specific working process is as follows: the mixing motor 61 drives the active disc A68 to rotate forward, the pawl A69 engages with the mixing plate 63, the active disc A68 drives the mixing plate 63 to rotate synchronously, and at the same time, the output shaft of the mixing motor 61 drives the rotating component A67 to rotate, the rotating component A67 drives the mixing rod 65 to rotate, the mixing rod 65 drives the mixing blade 66 to rotate, and the mixing blade 66 mixes the concrete in the mixing bucket 6 to prevent the concrete from losing its activity; when it is necessary to adjust the angle of the mixing rod 65, the electromagnet assembly 63 on the mixing plate 63 is attracted, the telescopic rod on the electromagnet assembly 63 drives the mixing rope 64 to move, the mixing rope 64 drives the mixing rod 65 to rotate, and the mixing rod 65 drives the mixing blade 66 to deflect at an angle, which can fully mix the concrete.

[0047] Once the pouring is complete and the required functions are achieved, use a crane to lift the device from the fixed block A12. Then, remove the inner mold 48, press the stop button, the device will be powered off, and all parts will stop working.
