Description

Technical Field

[0001] This invention relates to the technical field of concrete preparation, and more particularly to a production equipment for precast concrete components. Background Technology

[0002] Concrete, an artificial stone material, is made by mixing cement, sand, and water in a specific ratio and hardening it through a hydration reaction. It possesses high compressive strength, durability, and plasticity, making it the cornerstone of modern architecture. From skyscrapers to cross-sea bridges, from highways to dams, concrete forms the steel framework of human society and is the most widely used building material.

[0003] In automated production lines for precast concrete components, concrete placement, vibration, and conveying are the core processes. Traditional production processes typically set up the vibration table as an independent workstation. After the mold is placed, it needs to be paused on the conveyor line and transferred to a dedicated vibration table for vibration, then returned to the conveyor line to move to the next workstation. This intermittent "pause-vibration-restart" process severely restricts production cycle time and overall efficiency. Simultaneously, the frequent transfer of molds between multiple devices can easily cause disturbance before the concrete's initial setting, affecting molding quality and increasing the complexity and cost of equipment layout. Therefore, how to efficiently integrate vibration functions without interrupting continuous conveying, achieving "vibration on demand," has become a key technical challenge for improving the automation level and product homogeneity of precast component production. Summary of the Invention

[0004] The purpose of this invention is to provide a precast concrete component production equipment in order to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a concrete placing boom and a conveying device are included. The concrete placing boom is used to place concrete mixture into a mold, and the conveying device is used to receive and transport the mold containing the concrete mixture. The conveying device includes a housing installed at the lower end of the placing boom's discharge port. A roller assembly for conveying and vibrating precast concrete components is installed in the middle of the housing. A drive assembly for driving the roller assembly to rotate is installed at one end of the roller assembly. A control assembly for controlling the drive assembly is installed inside the housing. A power assembly for use with the roller assembly is also installed inside the housing.

[0006] In practical applications, this device innovatively integrates the vibration and conveying processes, significantly saving production line space. The roller assembly of its conveying device generates high-frequency vibration driven by the power unit, ensuring that the concrete within the mold placed on it is simultaneously and thoroughly vibrated during transport. This design achieves key processes such as concrete liquefaction, air bubble removal, and aggregate and paste densification. This not only ensures uniformity and defect-free internal structure of the components, significantly improving density, strength, and durability, but also achieves seamless integration of vibration and material movement through the coordination of control components. Thus, it optimizes the traditional production line process of separating material placement, vibration, and transfer, significantly improving production efficiency and automation while ensuring quality.

[0007] Furthermore, the shell includes multiple base plates, with foot supports installed at the lower end of each base plate, power boxes fixedly installed at both ends of each base plate, and a collection box installed in the middle of each base plate. The collection box can be used to recycle and reuse concrete scattered outside the mold, thus avoiding waste of resources.

[0008] The power assembly includes a movable plate slidably disposed at the bottom of a power box. A hinge plate is rotatably disposed on one outer wall of the movable plate. The end of the hinge plate is rotatably connected to an eccentric position on the outer wall of a rotating disk. A connecting rod is fixedly disposed at the center of the rotating disk. The connecting rod is connected to the output shaft of a motor. The motor is mounted on the outer wall of the power box. Multiple rollers are disposed at the lower end of the movable plate. The rollers are rotatably connected to the power box.

[0009] The roller assembly includes a rotating shaft with two power boxes passing through its two ends. The outer wall of each power box has a through hole for use with the rotating shaft, the diameter of which is larger than the diameter of the rotating shaft. A fixed shaft is fixedly installed at the end of the rotating shaft, and the lower end of the fixed shaft is hinged to a movable plate. Inside the power box, first guide rods are fixedly installed on both sides of the through hole. A mounting plate is slidably installed at the middle position of each first guide rod. Return springs are sleeved at both ends of each first guide rod. The rotating shaft passes through and is rotatably installed at the middle position of the mounting plate. Multiple fixed rods are fixedly installed at the end of the rotating shaft. A bushing can be rotatably fitted onto the outer wall of each fixed rod to reduce friction between the fixed rod and the connecting hole. Limit rings are fixedly installed on both outer walls of the rotating shaft.

[0010] In practical applications, when the roller assembly needs to vibrate, the motor is started first. The motor output shaft drives the rotating disk to rotate, the rotating disk drives the power box to swing, and the power box pulls the movable plate to reciprocate. Thus, the movable plate drives the fixed shaft to swing, and the swing of the fixed shaft drives the rotating shaft to move up and down quickly along the first guide rod, thereby generating a vibration effect at the upper end of the rotating shaft. Through mechanical vibration, the freshly mixed concrete is liquefied, internal air bubbles are expelled, and the aggregate and cement paste are closely arranged, thereby significantly improving the density, uniformity and strength of the concrete.

[0011] Furthermore, the drive assembly includes a rotating rod rotatably connected to the power box. The rotating rod is connected to the inner wall of the power box via a one-way bearing. A sprocket is fixedly installed at the middle position of the rotating rod, and all sprockets are connected by a chain. A turntable is fixedly installed at the end of the rotating rod. The outer wall of the turntable has a connecting hole for use with the fixed rod. The inner diameter of the connecting hole is larger than the outer diameter of the fixed rod. A rotating ring is rotatably connected to the outer wall of one of the turntables. A one-way bearing is installed between the rotating ring and the turntable. A sector plate is fixedly installed at the lower end of the rotating ring. The lower arc surface of the sector plate has teeth. A rack for use with the teeth is slidably installed on the outer wall of the movable plate.

[0012] In practical applications, when a rotating shaft is needed to transport the mold, the operator uses the control component to engage the rack with the teeth on the outer wall of the sector plate. This causes the movable plate to reciprocate, which in turn drives the sector plate to reciprocate. The sector plate then drives the rotating ring to reciprocate. When the rotating ring rotates clockwise, it drives the turntable to rotate, which in turn drives the fixed rod to rotate. The fixed rod then drives the rotating shaft to rotate, thus transporting the mold away from the discharge end of the concrete placing boom. At this point, the rotating ring and the turntable cannot rotate, but the rotating rod and the power box can rotate. Conversely, when the rotating ring rotates counterclockwise, the rotating shaft does not rotate, causing the mold to move in one direction. During this movement, the concrete can be vibrated. When the movement reaches the end, the vibration effect is no longer achieved, and the control component can disengage the rack from the sector plate.

[0013] Furthermore, the control component includes a compression assembly installed on the outer wall of the power box. The compression assembly is connected to a hose, and an adjustment assembly is installed at the lower end of the hose. A T-shaped tube is fixedly connected to the lower end of the adjustment assembly. Telescopic tubes are installed at both ends of the T-shaped tube, and the piston rod end of the telescopic tube is fixedly connected to the side wall of the rack.

[0014] The extrusion assembly is fixed to the pressure cylinder on the outer wall of the power box. A first sealing plate is slidably arranged in the middle of the pressure cylinder. A threaded cylinder is fixedly arranged in the middle of the outer wall of the first sealing plate. A threaded rod is threadedly connected inside the threaded cylinder. The threaded rod is rotatably connected to the pressure cylinder. A guide cylinder is arranged on the same side of the outer wall of the first sealing plate and the threaded cylinder. A second guide rod is slidably connected inside the guide cylinder. The hose is installed on the pressure cylinder at the end away from the threaded rod. The threaded rod can be rotated manually or by a motor.

[0015] The adjusting assembly includes a pressure regulating cylinder fixedly installed on the outer wall of the movable plate, a fixed tube fixedly installed in the middle position of the pressure regulating cylinder, a second sealing plate slidably installed at the upper end of the fixed tube, a second spring installed at the lower end of the second sealing plate, and the upper end of the fixed tube communicating with a hose.

[0016] In practical applications, when the threaded rod rotates forward, it moves the threaded cylinder, which in turn moves the first sealing plate away from the threaded rod. The first sealing plate injects gas from the pressure cylinder into the hose. Air in the hose enters the lower end of the pressure regulating cylinder, and air at the bottom of the pressure regulating cylinder enters the T-tube. Subsequently, air inside the T-tube enters the telescopic tube, which pushes the rack to move, thus disengaging the rack from the sector plate. Conversely, when the threaded rod rotates backward, the telescopic tube contracts. Because the rack is reciprocating, it cannot engage with the sector plate in one go. Therefore, a negative pressure is formed inside the telescopic tube, the T-tube, and the pressure regulating cylinder. This negative pressure causes the second sealing plate to move downward, thus maintaining a continuous negative pressure inside the telescopic tube, the T-tube, and the pressure regulating cylinder. When the rack engages with the sector plate, the telescopic tube contracts, restoring the air pressure inside the telescopic tube, the T-tube, and the pressure regulating cylinder to normal.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This device innovatively integrates vibration and conveying processes, significantly saving production line space. The roller assembly of its conveying device generates high-frequency vibration driven by a power unit, ensuring that the concrete within the mold placed on it is simultaneously and thoroughly vibrated during transport. This design achieves key processes such as concrete liquefaction, air bubble removal, and aggregate and paste densification. This not only ensures uniform and defect-free internal components, significantly improving density, strength, and durability, but also achieves seamless integration of vibration and material movement through the coordination of control components. Thus, it optimizes the traditional production line process of separating material placement, vibration, and transfer, significantly improving production efficiency and automation while ensuring quality.

[0019] When the threaded rod rotates forward, it moves the threaded cylinder, which in turn moves the first sealing plate away from the threaded rod. The first sealing plate injects gas from the pressure cylinder into the hose. Air in the hose enters the lower end of the pressure regulating cylinder, and air at the bottom of the pressure regulating cylinder enters the T-tube. Subsequently, air inside the T-tube enters the telescopic tube, which pushes the rack to move, thus disengaging the rack from the sector plate. Conversely, when the threaded rod rotates backward, the telescopic tube contracts. Because the rack is reciprocating, it cannot engage with the sector plate in one go, thus creating a negative pressure inside the telescopic tube, T-tube, and pressure regulating cylinder. This negative pressure causes the second sealing plate to move downward, maintaining a continuous negative pressure inside the telescopic tube, T-tube, and pressure regulating cylinder. When the rack engages with the sector plate, the telescopic tube contracts, restoring the air pressure inside the telescopic tube, T-tube, and pressure regulating cylinder to normal.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0032] Reference Figure 1-9 A precast concrete component production equipment includes a concrete placing boom and a conveying device. The concrete placing boom is used to place concrete mixture into a mold, and the conveying device is used to receive and transport the mold containing the concrete mixture. The conveying device includes a housing 2 installed at the lower end of the discharge port of the placing boom. A roller assembly 1 for conveying and vibrating the precast concrete component is installed in the middle of the housing 2. A drive assembly 4 for driving the roller assembly 1 to rotate is installed at one end of the roller assembly 1. A control assembly 3 for controlling the drive assembly 4 is installed inside the housing 2. A power assembly 5 for cooperating with the roller assembly 1 is also installed inside the housing 2.

[0033] In practical applications, this device innovatively integrates the vibration function with the conveying process, thereby significantly saving production line space. The roller assembly 1 of its conveying device generates high-frequency vibration under the drive of the power assembly 5, ensuring that the concrete in the mold placed on it is simultaneously and thoroughly vibrated during the conveying process. This design achieves key processes such as concrete liquefaction, air bubble removal, and aggregate and paste densification. This not only ensures uniformity and defect-free internal structure of the components, significantly improving density, strength, and durability, but also achieves seamless integration of vibration and moving material discharge through the coordination of the control assembly 3. Thus, it optimizes the traditional production line process of separating material placement, vibration, and transfer, significantly improving production efficiency and automation while ensuring quality.

[0034] Furthermore, the housing 2 includes multiple base plates 201, with foot supports installed at the lower end of the base plates 201, power boxes 202 fixedly installed at both ends of the base plates 201, and a collection box 203 installed in the middle of the base plates 201.

[0035] The power assembly 5 includes a movable plate 501 slidably disposed at the bottom of the power box 202. A hinge plate 502 is rotatably disposed on one outer wall of the movable plate 501. The end of the hinge plate 502 is rotatably connected to an eccentric position on the outer wall of the rotating disk 503. A connecting rod 504 is fixedly disposed at the center of the rotating disk 503. The connecting rod 504 is connected to the motor output shaft. The motor is mounted on the outer wall of the power box 202. A plurality of rollers 7 are disposed at the lower end of the movable plate 501. The rollers 7 are rotatably connected to the power box 202.

[0036] The roller assembly 1 includes a rotating shaft 101, with two power boxes 202 passing through both ends of the rotating shaft 101. The outer wall of the power box 202 has a through hole for use with the rotating shaft 101, the diameter of which is larger than the diameter of the rotating shaft 101. A fixed shaft 103 is fixedly installed at the end of the rotating shaft 101. The lower end of the fixed shaft 103 is hinged to a movable plate 501. A first guide rod 105 is fixedly installed on both sides of the through hole inside the power box 202. A mounting plate 104 is slidably installed at the middle position of the first guide rod 105. A return spring 106 is sleeved at both ends of the first guide rod 105. The rotating shaft 101 passes through and is rotatably installed at the middle position of the mounting plate 104. Multiple fixed rods 107 are fixedly installed at the end of the rotating shaft 101. The outer wall of the fixed rod 107 can be rotatably sleeved with a bushing to reduce the friction between the fixed rod 107 and the connecting hole 4031. Limit rings 102 are fixedly installed on both outer walls of the rotating shaft 101.

[0037] In practical applications, when the roller assembly 1 needs to vibrate, the motor is started first. The motor output shaft drives the rotating disk 503 to rotate, the rotating disk 503 drives the power box 202 to swing, and the power box 202 pulls the movable plate 501 to reciprocate. Thus, the movable plate 501 drives the fixed shaft 103 to swing. The swing of the fixed shaft 103 drives the rotating shaft 101 to move up and down quickly along the first guide rod 105, thereby generating a vibration effect at the upper end of the rotating shaft 101. Through mechanical vibration, the freshly mixed concrete is liquefied, internal air bubbles are expelled, and the aggregate and cement paste are closely arranged, thereby significantly improving the density, uniformity and strength of the concrete.

[0038] Furthermore, the drive assembly 4 includes a rotating rod 401 rotatably connected to the power box 202. The rotating rod 401 is connected to the inner wall of the power box 202 via a one-way bearing. A sprocket 402 is fixedly installed at the middle position of the rotating rod 401. All sprockets 402 are connected by a chain. A turntable 403 is fixedly installed at the end of the rotating rod 401. A connecting hole 4031 for use with the fixed rod 107 is opened on the outer wall of the turntable 403. The inner diameter of the connecting hole 4031 is larger than the outer diameter of the fixed rod 107. A rotating ring 404 is rotatably connected to the outer wall of one of the turntables 403. A one-way bearing is installed between the rotating ring 404 and the turntable 403. A sector plate 405 is fixedly installed at the lower end of the rotating ring 404. The arc surface at the lower end of the sector plate 405 is provided with teeth. A rack 406 for use with the teeth is slidably installed on the outer wall of the movable plate 501.

[0039] In practical applications, when the rotating shaft 101 needs to transport the mold, the operator uses the control component 3 to drive the rack 406 to mesh with the teeth on the outer wall of the sector plate 405. This causes the movable plate 501 to reciprocate, which in turn drives the sector plate 405 to reciprocate. The sector plate 405 then drives the rotating ring 404 to reciprocate. When the rotating ring 404 rotates clockwise, it drives the turntable 403 to rotate, which in turn drives the fixed rod 107 to rotate. 7 drives the rotating shaft 101 to rotate, thereby conveying the mold away from the discharge end of the concrete placing machine. At this time, the rotating ring 404 and the turntable 403 cannot rotate, while the rotating rod 401 and the power box 202 can rotate. Conversely, the rotating ring 404 reverses, and the rotating shaft 101 will not rotate, thereby causing the mold to move in one direction. During the movement, the concrete can be vibrated. When the movement reaches the end, the vibration effect is not achieved. At this time, the control component 3 can control the rack 406 to disengage from the sector plate 405.

[0040] Furthermore, the control component 3 includes a compression component 301 installed on the outer wall of the power box 202. The compression component 301 is connected to a hose 302. An adjustment component 303 is installed at the lower end of the hose 302. A T-tube 304 is fixedly connected to the lower end of the adjustment component 303. Telescopic tubes 305 are installed at both ends of the T-tube 304. The piston rod end of the telescopic tube 305 is fixedly connected to the side wall of the rack 406.

[0041] The extrusion assembly 301 is fixed to the pressure cylinder 3011 on the outer wall of the power box 202. A first sealing plate 3012 is slidably arranged in the middle position of the pressure cylinder 3011. A threaded cylinder 3013 is fixedly arranged in the middle position of the outer wall of the first sealing plate 3012. A threaded rod 3014 is threadedly connected inside the threaded cylinder 3013. The threaded rod 3014 is rotatably connected to the pressure cylinder 3011. A guide cylinder 3015 is arranged on the same side of the outer wall of the first sealing plate 3012 and the threaded cylinder 3013. A second guide rod 3016 is slidably connected inside the guide cylinder 3015. A hose 302 is installed on the pressure cylinder 3011 at the end away from the threaded rod 3014. The threaded rod 3014 can be rotated manually or by a motor.

[0042] The adjusting assembly 303 includes a pressure regulating cylinder 3031 fixedly installed on the outer wall of the movable plate 501. A fixing tube 3032 is fixedly installed in the middle position of the pressure regulating cylinder 3031. A second sealing plate 3034 is slidably installed at the upper end of the fixing tube 3032. A second spring 3033 is installed at the lower end of the second sealing plate 3034. The upper end of the fixing tube 3032 is connected to the hose 302.

[0043] In practical applications, when the threaded rod 3014 rotates clockwise, it causes the threaded cylinder 3013 to move. This, in turn, causes the first sealing plate 3012 to move away from the threaded rod 3014. The first sealing plate 3012 injects gas from the pressure cylinder 3011 into the hose 302. Air in the hose 302 enters the lower end of the pressure regulating cylinder 3031, while air at the bottom of the pressure regulating cylinder 3031 enters the T-tube 304. Subsequently, air inside the T-tube 304 enters the telescopic tube 305, which pushes the rack 406 to move, thus disengaging the rack 406 from the sector plate 405. When the threaded rod 3014 reverses, the telescopic tube 305 retracts. Since the rack 406 is reciprocating, it cannot engage with the sector plate 405 in one go. Therefore, a negative pressure is formed inside the telescopic tube 305, the T-tube 304, and the pressure regulating cylinder 3031. The negative pressure causes the second sealing plate 3034 to move downward, thus maintaining a continuous negative pressure inside the telescopic tube 305, the T-tube 304, and the pressure regulating cylinder 3031. When the rack 406 engages with the sector plate 405, the telescopic tube 305 retracts, restoring the air pressure inside the telescopic tube 305, the T-tube 304, and the pressure regulating cylinder 3031 to normal.

[0044] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
