Description

Technical Field

[0001] This application relates to the field of reinforced concrete precast column technology, and in particular to a casting device for producing reinforced concrete stiffened precast columns. Background Technology

[0002] Reinforced concrete precast columns are a common type of building structural component. Compared to ordinary precast columns, reinforced concrete precast columns are structures composed of steel sections encased in concrete. They are typically used in the frame structures of multi-story or high-rise buildings to minimize cross-sections, maximize load-bearing capacity, and save space. Common types include H-shaped steel reinforced concrete columns, cross-shaped steel reinforced concrete columns, and circular steel reinforced concrete columns. Current technology involves prefabrication in factories and transportation to the construction site for installation.

[0003] When casting conventional precast columns, various casting devices are used. Existing conventional casting devices are only designed for casting conventional reinforced cage precast columns. A crane lifts the hopper, and operators simply control the hopper's position. The hopper's outlet directly pours concrete onto the reinforcing cage, and the concrete fills the mold under the assistance of gravity and vibrators. However, in the production of reinforced concrete stiffened precast columns, the hopper's outlet needs to avoid the steel profiles. Therefore, workers are required to support the hopper when moving it and adjust the discharge direction according to the concrete flow direction, resulting in a high workload for workers. This requires improvement. Utility Model Content

[0004] In order to provide a casting device for the production of reinforced concrete rigid precast columns, and to solve the problem that the hopper needs to be supported by workers when it is moved, and the control lever needs to be manually pulled to adjust the discharge direction, which is labor-intensive, this application provides a casting device for the production of reinforced concrete rigid precast columns.

[0005] The casting device for producing reinforced concrete precast columns provided in this application adopts the following technical solution:

[0006] A casting device for producing reinforced concrete precast columns includes a frame and a control mechanism. Two supports are fixedly mounted on the upper surface of the frame, and a hopper is fixedly mounted on one side of each support that is close to each other. The control mechanism includes two concave plates mounted on the front and back of the frame. Two square tubes are provided below each concave plate. Two perforated sliders are slidably connected to the inner wall of each concave plate. The bottom surfaces of the two sets of perforated sliders are fixedly mounted to the upper surfaces of the two sets of square tubes. Two positive and negative threaded rods are slidably connected to the inner walls of the two sets of perforated sliders. A stepper motor is fixedly mounted on the left end of each concave plate. The output ends of the two stepper motors are respectively fixedly installed to the left ends of the two positive and negative threaded rods. A square rod is slidably connected to the inner wall of each square tube. Two base plates are fixedly installed on the bottom surfaces of the two sets of square rods. A set of universal wheels is fixedly installed on the bottom surfaces of the two base plates. Two bearing seats are fixedly installed on the side of the two sets of square tubes that are close to each other. Two sets of rotating rollers are rotatably installed on the inner rings of the two sets of bearing seats. A tilting cylinder is fixedly installed on the front of the hopper. A rotating shaft is rotatably installed on the output end of the tilting cylinder. Two adjusting plates are fixedly installed on the outer surface of the rotating shaft. Two baffles are fixedly installed on the inner wall of the hopper.

[0007] By adopting the above technical solution, the device is first pushed to move the two base plates to both sides of the mold. Then, the stepper motor is started, driving the positive and negative threaded rods to rotate. The threaded connection between the positive and negative threaded rods and the perforated slider causes the perforated slider to move the square cylinder. The square cylinder, through the square rod, moves the base plates closer to the mold plate, where the rotating roller contacts the mold plate, reducing swaying of the hopper during movement. A tilting cylinder is controlled to rotate the rotating shaft, which in turn rotates the adjusting plate, controlling the discharge direction of the hopper. This device moves along the mold direction, minimizing hopper swaying, eliminating the need for manual support, reducing the workload of workers, and lowering the manpower required for pouring operations.

[0008] Optionally, an arc-shaped plate is fixedly installed on the outer surface of the rotating shaft, and the two ends of the arc-shaped plate are respectively fixedly installed on the side of the two adjusting plates near the rotating shaft.

[0009] By adopting the above technical solution, the tilting cylinder drives the rotating shaft to rotate, which in turn drives the adjusting plates to rotate. This causes one adjusting plate to contact one of the baffle bars, while the other adjusting plate separates from the baffle bar, thus forming a discharge channel for concrete to be discharged. Furthermore, the tilting cylinder reverses its direction, causing both adjusting plates to flip, thereby controlling the switching of the discharge channel between the adjusting plates and the baffle bars, and thus controlling the discharge direction of the hopper.

[0010] Optionally, a mudguard is provided below the tilting cylinder, and the back of the mudguard is fixedly installed with the front of the hopper.

[0011] By adopting the above technical solution, concrete splashes onto the tilting cylinder during pouring are prevented.

[0012] Optionally, a hydraulic rod is fixedly installed on the inner top wall of each of the square tubes, and the telescopic end of each hydraulic rod is fixedly installed to the top of the square tube.

[0013] By adopting the above technical solution, the square tube is lifted and lowered by a hydraulic rod, and the lifting and lowering of the square tube drives the lifting and lowering of the concave plate, so that the height of the hopper can be adjusted according to the size of the precast column to be poured.

[0014] Optionally, each of the square tubes has a limiting groove on its front and back sides, and a limiting block is slidably connected to the inner wall of each limiting groove. The sides of the two sets of limiting blocks that are close to each other are fixedly installed to the front and back sides of the two sets of square rods, respectively.

[0015] By adopting the above technical solution, the hydraulic rod is activated, and the hydraulic rod extends to drive the square tube to rise relative to the square rod. The limiting block moves downward relative to the limiting groove. The sliding connection between the outer wall of the limiting block and the inner wall of the limiting groove 5 can improve the stability of the square tube's lifting and lowering.

[0016] Optionally, a connecting flange is fixedly connected to the left side of the hopper, and a control panel is fixedly installed on the right side of the frame.

[0017] By adopting the above technical solution, the concrete conveying pipeline is connected to the connecting flange, allowing the concrete to enter the hopper.

[0018] Optionally, a fixing seat is fixedly installed on both the left and right sides of the frame, and the side of the two fixing seats that are far apart from each other is fixedly installed on the side of the two concave plates that are close to each other.

[0019] Optionally, a limiting ring is fixedly installed on the outer surface of each of the positive and negative threaded rods, and the two limiting rings are respectively located in the middle of the two positive and negative threaded rods.

[0020] By adopting the above technical solution, the outer peripheral wall of the limiting ring and the inner wall of the concave plate are fixedly connected by a short rod to improve the stability of the rotation of the positive and negative threaded rods.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. In use, first push the device to move the two base plates to both sides of the mold. Then start the stepper motor to drive the positive and negative threaded rods to rotate. Utilizing the threaded connection between the positive and negative threaded rods and the perforated slider, the perforated slider moves the square cylinder. The square cylinder, through the square rod, moves the base plate closer to the mold plate, and the rotating roller contacts the mold plate, reducing the shaking of the hopper during movement. By controlling the tilting cylinder to drive the rotating shaft to rotate, the rotating shaft drives the adjusting plate to rotate, and the adjusting plate controls the discharge direction of the hopper.

[0023] 2. By using a combination of a tilting cylinder, a rotating shaft, an adjusting plate, and a stop bar, the rotation of the two adjusting plates can be controlled, thereby adjusting the discharge direction. Furthermore, by using a stepper motor, positive and negative threaded rods, a perforated slider, a square tube, and a square rod, the rotating roller can contact the mold and limit the movement of the device, allowing it to move along the mold direction and preventing the hopper from shaking. This eliminates the need for manual support, reducing the workload of workers and the manpower required for pouring operations. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0030] This application discloses a casting device for producing reinforced concrete stiffened precast columns. (Refer to...) Figure 1 A casting device for producing reinforced concrete precast columns includes a frame 1. Two supports 101 are fixedly installed on the upper surface of the frame 1, and a hopper 102 is fixedly installed on the side of the two supports 101 that are close to each other. A control mechanism 2 is provided on the frame 1. The control mechanism 2 includes two recessed plates 201 installed on the front and back of the frame 1. Fixing seats 3 are fixedly installed on both the left and right sides of the frame 1, and the side of the two fixing seats 3 that are far from each other is fixedly installed to the side of the two recessed plates 201 that are close to each other. A control panel 103 is fixedly installed on the right side of the frame 1.

[0031] Reference Figure 1 and Figure 2 Each concave plate 201 has two square tubes 202 below it, combined with Figure 4 Each square tube 202 has a hydraulic rod 216 fixedly installed on its inner top wall, and the telescopic end of each hydraulic rod 216 is fixedly installed to the top of the square rod 204. Each concave plate 201 has two perforated sliders 215 slidably connected to its inner wall. The bottom surfaces of the two sets of perforated sliders 215 are fixedly installed to the upper surfaces of the two sets of square tubes 202, respectively. The inner walls of the two sets of perforated sliders 215 are slidably connected to two threaded rods 214. Each concave plate 201 has a stepper motor 217 fixedly installed on its left end, and the output ends of the two stepper motors 217 are fixedly installed to the left ends of the two threaded rods 214, respectively. Each square tube 202 has a square rod 204 slidably connected to its inner wall, and the bottom surfaces of the two sets of square rods 204 are fixedly installed to two base plates 205. Each base plate 205 has a set of casters 206 fixedly installed to its bottom surface. Two bearing seats 208 are fixedly installed on one side of the two sets of square tubes 202 that are close to each other. Two sets of rollers 203 are installed on the inner rings of the two sets of bearing seats 208 that rotate together.

[0032] In operation, the device is first moved to one side of the mold. The square cylinder 202 is then raised and lowered via the hydraulic rod 216. This movement of the square cylinder 202 raises and lowers the concave plate 201, allowing the hopper 102 to be adjusted in height according to the required dimensions of the precast column. Next, the device is moved to the sides of the mold by the two base plates 205. Then, the stepper motor 217 is activated, causing the positive and negative threaded rods 214 to rotate. The threaded connection between the positive and negative threaded rods 214 and the perforated slider 215 drives the perforated slider 215 to move. The perforated slider 215 then moves the square cylinder 202, which in turn moves the base plate 205 via the square rod 204. The base plate 205, via the casters 206, approaches the mold template, causing the rotating roller 203 to contact the template and limit the device's movement, thus preventing the hopper 102 from wobbling during movement. During the movement of the device, the rotating roller 203 contacts and rotates with the template, allowing the device to move along the template direction.

[0033] Reference Figure 4 Each threaded rod 214 has a limiting ring 6 fixedly installed on its outer surface. The two limiting rings 6 are located in the middle of the two threaded rods 214 respectively. The outer peripheral wall of the limiting ring 6 is fixedly connected to the inner wall of the concave plate 201 by a short rod to improve the stability of the rotation of the threaded rod 214.

[0034] Reference Figure 1 and Figure 3 A connecting flange 209 is fixedly connected to the left side of the hopper 102. A tilting cylinder 207 is fixedly installed on the front of the hopper 102. A rotating shaft 212 is rotatably installed at the output end of the tilting cylinder 207. Two adjusting plates 213 are fixedly installed on the outer surface of the rotating shaft 212. Two baffles 210 are fixedly installed on the inner wall of the hopper 102. An arc-shaped plate 211 is fixedly installed on the outer surface of the rotating shaft 212. The two ends of the arc-shaped plate 211 are respectively fixedly installed on the side of the two adjusting plates 213 near the rotating shaft 212. A mudguard 4 is provided below the tilting cylinder 207. The back of the mudguard 4 is fixedly installed on the front of the hopper 102. The mudguard 4 is arc-shaped to prevent concrete from splashing onto the tilting cylinder 207 during pouring.

[0035] The concrete delivery pipe is connected to the connecting flange 209, allowing concrete to enter the hopper 102. The tilting cylinder 207 drives the rotating shaft 212 to rotate, which in turn drives the adjusting plates 213 to rotate. This causes one adjusting plate 213 to contact one of the baffles 210, while the other adjusting plate 213 separates from the baffle 210, thus forming a discharge channel for concrete discharge. Furthermore, the tilting cylinder 207 reverses, causing both adjusting plates 213 to flip, thereby controlling the switching of the discharge channel between the adjusting plates 213 and the baffles 210, and thus controlling the discharge direction of the hopper 102.

[0036] Reference Figure 2 and Figure 4 Each square tube 202 has a limiting groove 5 on both its front and back sides. A limiting block 501 is slidably connected to the inner wall of each limiting groove 5. The sides of the two sets of limiting blocks 501 that are close to each other are fixedly installed to the front and back sides of the two sets of square rods 204, respectively. When the hydraulic rod 216 is activated, its hydraulic rod extends, driving the square tube 202 to rise relative to the square rods 204. The limiting blocks 501 move downwards relative to the limiting grooves 5. The sliding connection between the outer wall of the limiting block 501 and the inner wall of the limiting groove 5 improves the stability of the square tube 202's lifting and lowering.

[0037] The implementation principle of the casting device for producing reinforced concrete precast columns according to this application embodiment is as follows: First, the device is moved to one side of the mold. Then, the device is pushed to move the two base plates 205 to both sides of the mold. Next, the hydraulic rod 216 is activated, causing the hydraulic rod 216 to push the square rod 204 to slide along the square tube 202, thereby adjusting the height of the concave plate 201 and the frame 1. This allows the hopper 102 to be height-adjusted according to the required size of the precast column to be cast. Then, the stepper motor 217 is activated, causing the stepper motor 217 to drive the positive and negative threaded rods 214 to rotate. Utilizing the threaded connection between the positive and negative threaded rods 214 and the perforated slider 215, the perforated slider 215 drives the square tube 202. The square tube 202, through the square rod 204, drives the base plate 205 to move. The base plate 205, through the universal wheels 206, approaches the template, causing the rotating roller 203 to contact the template, thus limiting the device and preventing the hopper 102 from shaking during movement.

[0038] The concrete conveying pipe is connected to the connecting flange 209, allowing concrete to enter the hopper 102. Then, the tilting cylinder 207 is activated, causing the rotating shaft 212 to rotate. This, in turn, causes the adjusting plate 213 to rotate, resulting in one adjusting plate 213 contacting one baffle 210 and the other separating from it, thus forming a discharge channel for concrete discharge. The tilting cylinder 207 then reverses, causing both adjusting plates 213 to flip, controlling the switching of the discharge channel between the adjusting plates 213 and the baffle 210, thereby controlling the discharge direction of the hopper 102. The device is then pushed, allowing it to move via the casters 206. Simultaneously, the rotating roller 203 contacts the template, enabling the device to move along the template direction, thus completing the pouring process.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
