Description

Technical Field

[0001] This invention relates to the field of concrete demolding technology, specifically to an automated production line for high-strength concrete pipes and a hydraulic demolding device. Background Technology

[0002] Existing concrete pipe production lines, when producing concrete pipes using molds, typically employ a unidirectional (upward or downward) lifting or pulling method to separate the mold from the concrete pipe. For example, a common method is to use a forklift to lift the mold upwards to achieve separation. This approach has several significant drawbacks: First, the mold or pallet needs to move the entire length of the pipe, resulting in slow demolding speed and low efficiency. Second, during the long demolding stroke, the mold is prone to skew, causing uneven friction and pressure against the inner wall of the concrete pipe. This can easily lead to quality problems such as scratches, adhesion, and even structural cracks on the concrete pipe surface, resulting in a lower yield. Furthermore, at the pouring station, the splashing and falling of concrete residue not only wastes raw materials but also pollutes the working environment. Summary of the Invention

[0003] The purpose of this invention is to provide an automated production line for high-strength concrete pipes and a hydraulic demolding device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an automated production line for high-strength concrete pipes, comprising a feeding station, a spraying station, a pouring station, and a material unloading platform, wherein the feeding station is used to transport molds and pallets to the spraying station; The spraying station is used to apply a release agent to both the inner wall of the mold and the surface of the pallet. The casting station has two casting points and is used to alternately cast and demold the two molds; The unloading platform is used to receive the concrete pipes after demolding.

[0005] Preferably, the pouring station includes a rotating plate, on which trays and molds in a docking state are provided on both the left and right sides; a receiving frame is provided below the rotating plate at the bottom of the left mold, the receiving frame is used to receive concrete residue that falls during pouring; an electric base is installed at the bottom of the rotating plate, the upper end of the output shaft of the electric base is fixedly connected to the center part of the rotating plate.

[0006] Preferably, the spraying station includes a base and two four-axis robotic arms mounted on the base. The ends of the four-axis robotic arms are equipped with electric clamps, which are used to clamp the tray and the mold respectively to adjust the spraying angle.

[0007] Preferably, the feeding station includes two feeding plates distributed vertically, with the upper and lower feeding plates respectively used to transport the mold and the pallet.

[0008] A high-strength concrete pipe hydraulic demolding device includes an electric base two and a frame mounted on the output shaft of the electric base two, characterized in that: a rotating frame is installed at both the front and rear positions on the frame; The rotating frame is equipped with a clamping assembly, which is used to clamp the mold and the pallet; The rotating frame is equipped with a hydraulic assembly, which is used to simultaneously drive the clamping assembly to move the mold and the pallet in the opposite direction in a straight line. The frame is equipped with a drive assembly, which is used to drive the rotating frames at the front and rear positions to move closer to each other.

[0009] Preferably, the clamping assembly includes a vertically formed slide groove on the rotating frame, with a slider one and a slider two slidably connected at their upper and lower positions respectively in the slide groove, and a clamping plate one and a clamping plate two fixedly connected to the slider one and slider two respectively; the side wall of the support plate is provided with multiple positioning holes, and multiple positioning rods are fixedly connected to the clamping plate two, with the multiple positioning rods and multiple positioning holes having clearance fit.

[0010] Preferably, the hydraulic assembly includes a hydraulic rod fixed in the middle of the rotating frame. The output end of the hydraulic rod is fixedly connected to docking blocks on both the front and rear sides. A connecting rod is rotatably connected to the docking blocks, and the other end of the connecting rod is rotatably connected to a clamping plate. Rollers are rotatably connected to both the front and rear sides above the rotating frame. Pull ropes are wound around the rollers, and the two ends of the pull ropes are fixedly connected to clamping plate one and clamping plate two, respectively.

[0011] Preferably, a second roller is rotatably connected to the docking block, and a support plate is fixedly connected to the rotating frame at the bottom position of the second roller, with the second roller in contact with the support plate.

[0012] Preferably, the drive assembly includes two hydraulic rods symmetrically distributed on the front and rear sides of the frame and rotatably connected to the frame, with the output ends of the hydraulic rods on the front and rear sides respectively rotatably connected to the rotating frames on the front and rear sides; the rotating frames are rotatably connected to the frame.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention uses a hydraulic component to drive the clamping component, causing the mold and pallet to move synchronously in opposite directions along a straight line during demolding. This decomposes the traditional single stroke into two opposing half-stroke movements, thereby reducing the demolding time by nearly half and greatly improving demolding efficiency. Simultaneously, the reverse linear motion ensures the alignment of the mold with the concrete pipe during separation, effectively avoiding surface damage to the pipe caused by misalignment, and significantly improving product molding quality and yield.

[0014] 2. This invention constructs an automated production line encompassing feeding, spraying, casting, and unloading, employing a design combining dual-station casting points with a rotatable rotating plate. This achieves parallel operation and seamless integration of spraying, casting, and demolding processes. The compact and rational layout, with a high degree of automation, not only significantly reduces manual intervention and improves overall production efficiency but also reduces material waste and improves the working environment of the unloading platform by collecting casting residue through a receiving frame.

Detailed Implementation

[0017] Please see Figure 1-4The present invention provides a technical solution: an automated production line for high-strength concrete pipes, including a feeding station, a spraying station, a pouring station and a material unloading platform 1. The feeding station is used to transport the mold 2 and the pallet 3 to the spraying station. The spraying station is used to apply release agent to the inner wall of mold 2 and the surface of tray 3; The pouring station has two pouring points, which are used to alternately pour and demold the two molds 2; The unloading platform 1 is used to receive the concrete pipes after demolding; At work, ( Figure 1 (x, y, and z in the text represent the front, right, and top directions, respectively.) When producing concrete pipes, the mold 2 and pallet 3 are transported to the spraying station by starting the feeding station. The release agent is evenly sprayed onto the inner wall of the mold 2 and the upper surface of the pallet 3 by the spraying station. Then, the sprayed mold 2 and pallet 3 are assembled and placed at the pouring point on the left side of the pouring station. Before pouring, the steel reinforcement frame is placed into the mold 2. Then, the pouring equipment is started to pour concrete into the mold 2. After the concrete pipe is poured, remove the mold 2 and the concrete pipe, and transport the pallet 3 and the poured concrete pipe to the unloading platform 1.

[0018] See Figure 4 As a further embodiment of the present invention, the pouring station includes a rotating plate 4, and a support plate 3 and a mold 2 in a docking state are provided on both the left and right sides of the rotating plate 4; a receiving frame 5 is provided at the bottom of the left mold 2 below the rotating plate 4, and the receiving frame 5 is used to receive concrete residue that falls during pouring; an electric base 6 is installed at the bottom of the rotating plate 4, and the upper end of the output shaft of the electric base 6 is fixedly connected to the center part of the rotating plate 4. During operation, when the mold 2 and pallet 3, after being coated with release agent and assembled, are placed at the pouring point on the left side of the rotating plate 4, the concrete pipe that has been poured at the pouring point on the right side of the rotating plate 4 is ready to be demolded. When concrete is poured into the mold 2 on the left side of the rotating plate 4, the mold 2 on the right side begins to demold. Since dry-hard concrete is used during pouring, some concrete residue is often easily dropped during pouring. By setting a receiving frame 5 below the pouring point on the left side of the rotating plate 4, the dropped concrete residue can be collected, thereby saving concrete and preventing concrete residue from falling and damaging the environment. After the pouring point on the left is completed, the pouring point on the right is simultaneously demolded. At this time, the electric base 6 is started to drive the rotating plate 4 to rotate half a turn, so that the positions of the pouring points on the left and right sides can be swapped.

[0019] See Figure 3As a further embodiment of the present invention, the spraying station includes a base and two four-axis robotic arms 7 mounted on the base. The ends of the four-axis robotic arms 7 are equipped with electric clamps 8, and the two electric clamps 8 are used to clamp the tray 3 and the mold 2 respectively to adjust the spraying angle. The feeding station includes two feeding plates 9 distributed vertically, and the upper and lower feeding plates 9 are used to transport the mold 2 and the pallet 3 respectively; During operation, the mold 2 and the pallet 3 are transported to the spraying station by the feeding plates 9 on the upper and lower sides. Then, the two four-axis robotic arms 7 and the electric clamping plate 8 at the spraying station are activated to clamp the mold 2 and the pallet 3 respectively. The spraying equipment is started to spray the release agent. At the same time, the angle of the mold 2 and the pallet 3 is continuously adjusted by the four-axis robotic arms 7, so as to achieve the effect of evenly applying the release agent to the inner wall of the mold 2 and the surface of the pallet 3. After applying the release agent, the four-axis robotic arm 7 reassembles the tray 3 and mold 2 and places them on the pouring point on the left side of the rotating plate 4.

[0020] See Figure 5-10 A high-strength concrete pipe hydraulic demolding device includes an electric base 2 10 and a frame 11 installed on the output shaft of the electric base 2 10, characterized in that: a rotating frame 12 is installed at both the front and rear positions on the frame 11. The rotating frame 12 is equipped with a clamping assembly, which is used to clamp the mold 2 and the tray 3; A hydraulic assembly is installed on the rotating frame 12. The hydraulic assembly is used to simultaneously drive the clamping assembly to move the mold 2 and the pallet 3 in the opposite direction in a straight line. The frame 11 is equipped with a drive assembly, which is used to drive the rotating frames 12 at the front and rear positions to move closer to each other. During operation, when it is necessary to separate the poured concrete pipe from the mold 2, the two rotating frames 12 in the front and rear positions can be driven to move closer to each other by activating the drive assembly. After the rotating frames 12 in the front and rear positions move closer, they will drive the clamping assembly to clamp the mold 2 and the pallet 3 at the same time. After the mold 2 and the pallet 3 are clamped, the frame 11 is driven to rotate half a turn. The frame 11, through the clamping assembly, causes the mold 2, the pallet 3, and the poured concrete pipe to detach from the rotating plate 4. After the frame 11 rotates half a turn, the hydraulic assembly is activated. The hydraulic assembly drives the clamping assembly to move, which in turn causes the mold 2 and the pallet 3 to move up and down respectively. The mold 2 and the pallet 3 move in opposite directions at the same time. Compared with the traditional method of demolding by moving the mold 2 upward, this method can effectively reduce the stroke of the mold 2 by half, thereby improving the demolding efficiency.

[0021] See Figure 4-5As a further embodiment of the present invention, the clamping assembly includes a slide groove 13 vertically formed on the rotating frame 12, with a slider 14 and a slider 2 slidably connected at the upper and lower positions respectively in the slide groove 13, and a clamping plate 16 and a clamping plate 2 17 fixedly connected to the slider 14 and the slider 2 15 respectively; a plurality of positioning holes 18 are formed on the side wall of the support plate 3, and a plurality of positioning rods 19 are fixedly connected to the clamping plate 2 17, with the plurality of positioning rods 19 and the plurality of positioning holes 18 in clearance fit; During operation, when the two rotating frames 12 are closed, they will respectively drive the clamping plates 16 on the front and rear sides to clamp the mold 2, and at the same time drive the clamping plates 17 on the front and rear sides to clamp the pallet 3. Since the pallet 3 mainly bears the weight of the concrete pipe, when the clamping plates 17 clamp the pallet 3, the positioning rod 19 on the clamping plates 17 is directly inserted into the positioning hole 18 on the pallet 3. At this time, the stability of the clamping plates 17 in holding the pallet 3 can be effectively improved through the action of the positioning rod 19 and the positioning hole 18.

[0022] See Figure 6-7 , Figure 9 As a further embodiment of the present invention, the hydraulic assembly includes a hydraulic rod 20 fixed in the middle of the rotating frame 12. A docking block 21 is fixedly connected to both the front and rear sides of the output end of the hydraulic rod 20. A connecting rod 22 is rotatably connected to the docking block 21, and the other end of the connecting rod 22 is rotatably connected to a clamping plate 17. Rollers 23 are rotatably connected to both the front and rear sides above the rotating frame 12. A pull rope 24 is wound around the roller 23, and both ends of the pull rope 24 are fixedly connected to a clamping plate 16 and a clamping plate 17, respectively. A second roller 25 is rotatably connected to the docking block 21, and a support plate 26 is fixedly connected to the rotating frame 12 at the bottom position of the second roller 25. The second roller 25 is in contact with the support plate 26. During operation, when the drive mold 2 needs to be separated from the concrete pipe, the support plate 3 directly supports the concrete pipe, so the support plate 3 requires a large force to maintain its supporting performance. The hydraulic rod 20 acts directly on the clamping plate 17 through two connecting rods 22. The force of the hydraulic rod 20 can ensure the supporting performance of the support plate 3. At the same time, the roller 25, in conjunction with the support plate 26, can further improve the stability of the upper end of the connecting rod 22. When the hydraulic rod 20 is activated to retract, the clamping plate 17 drives the support plate 3 to move downward, and the support plate 3 drives the concrete pipe to move downward. When clamping plate 2 17 moves downward, clamping plate 2 17 can pull clamping plate 1 16 upward through the pull rope 24 and roller 1 23. Clamping plate 1 16 then drives mold 2 upward. By moving mold 2 upward and support plate 3 downward, the travel distance of mold 2 and support plate 3 can be effectively reduced, the demolding time required can be reduced, and the demolding efficiency can be improved. In addition, since clamping plate 1 16 and clamping plate 2 17 slide in the straight groove 13 through slider 1 14 and slider 2 15, clamping plate 1 16 and clamping plate 2 17 can be guaranteed to move in a straight line at all times, which can effectively avoid damage to the concrete pipe caused by the mold 2 deviating from the direction of movement during demolding.

[0023] See Figure 5 As a further embodiment of the present invention, the drive assembly includes two hydraulic rods 27 symmetrically distributed on the front and rear sides of the frame 11 and rotatably connected to the frame 11. The output ends of the hydraulic rods 27 on the front and rear sides are respectively rotatably connected to the rotating frames 12 on the front and rear sides; the rotating frames 12 are rotatably connected to the frame 11. During operation, when it is necessary to drive the front and rear rotating frames 12 to close, the hydraulic rods 27 on the front and rear sides are activated, and the hydraulic rods 27 on the front and rear sides respectively drive the rotating frames 12 on the front and rear sides to rotate and close together.
