Description

Technical Field

[0001] The invention relates to the technical field of building engineering construction, and in particular to a PC component turning machine. Background Art

[0002] Prefabricated buildings are characterized by standardized design, factory production, assembled construction, and information-based management. They integrate the entire industry chain of design, production, construction, operation, and maintenance, and achieve energy conservation, environmental protection, and maximum value of the entire life cycle of building products. They are a new type of building form, which is one of the important forms of sustainable development in the construction industry.

[0003] At present, most prefabricated components are produced in a factory-like manner in workshops. They have high strength and stable quality. They work in three shifts, which greatly shortens the construction period. A large amount of work has been transformed from high-altitude operations to intelligent and automated production, which is safe and guaranteed, and conforms to the concept of green, energy-saving and environmental protection. Prefabricated concrete buildings have become the most common form of prefabricated buildings in my country, and are also one of the main directions of the development of my country's building industrialization.

[0004] The PC components (precast concrete) commonly used in industrial production are divided into single-sided and double-sided. The process of single-sided components is relatively simple, including marking on the formwork, placing steel trusses, pouring, vibrating, curing in curing kilns, testing, demolding, and delivery. Double-sided cavity prefabricated components are divided into A side and B side for secondary prefabrication. In addition to the prefabrication process of single-sided components, each side has an additional turning process. For double-sided cavity prefabricated components, a very important part of prefabrication in the workshop is turning over and pouring the other side (ie, B side) in the workshop. At present, the common scale of the component production line is 9m×4m, the maximum width of the component is 3.5m, and the weight is within 100kN.

[0005] However, the existing PC component turning over is to use a gantry crane to lift the mold base in the air and then rotate it over, which has high requirements on the lifting weight and space height of the workshop; especially for PC components with large size and weight, it is difficult to turn over the PC component, and the method of lifting the mold base in the air and then rotating it over has large turning inertia and high operation difficulty. Summary of the invention

[0006] The purpose of the present invention is to overcome the shortcomings of the prior art that PC components are difficult to flip, have high requirements on the workshop, and are difficult to operate, and to provide a PC component flipping machine.

[0007] In a first aspect, the present invention provides a PC component turning machine, comprising a driving assembly, two gear rings and at least two mold tables, wherein the driving assembly is in driving connection with the gear rings, the driving assembly is used to drive the gear rings to rotate, a machine body is arranged between the two gear rings, and the gear rings can drive the machine body to rotate together; the machine body is equipped with a mold table bracket, the mold table brackets are arranged relatively, and the mold table brackets can be extended and retracted along the radial direction of the machine body; the mold table bracket is provided with a mold table running wheel on one side close to the axis of the machine body, the mold table running wheel is in contact with the mold table, and the mold table running wheel is used to guide at least one of the mold tables to move along the axial direction of the machine body.

[0008] The PC component turning machine provided by the present invention can realize the in-situ turning of the PC component by driving the driving assembly and the gear ring, and the gear ring drives the entire machine body to rotate. Compared with the traditional method of lifting the mold table and then turning it over, the operation is simpler, the turning time is saved, and the production efficiency is improved; the PC component turning machine provided by the present invention, because the turning process is realized mechanically on the ground, there is no need for a crane to lift the mold table in the air to turn it over, which greatly reduces the turning inertia, the operation difficulty is low, the danger of operation is reduced, and the potential accident risk during the lifting process is reduced; the design of the PC component turning machine provided by the present invention reduces the dependence on the workshop height and lifting capacity, and is suitable for various production environments. Especially in workshops with limited space, there is no need to increase the workshop height or expand the lifting equipment, saving the infrastructure cost; by designing a retractable mold table bracket, the mold table height can be adjusted to be consistent with the mold table height of the previous process of the production line during use, so that the PC component can be quickly moved into the PC component turning machine. After the PC component is moved into place, the retractable mold table bracket can stably clamp the PC component to ensure the subsequent safe turning of the PC component. The PC component flipping machine is equipped with mold platforms on both the upper and lower sides of the PC component, which can adapt to both single-sided PC components and double-sided PC components, and has a wider range of applications; compared with the traditional method of lifting the mold platform and then flipping it, it can realize the in-situ flipping of PC components. After the A side of the PC component is poured, it can be directly flipped in place to pour the B side, without disrupting the factory assembly line construction rhythm, improving construction efficiency and quality, and shortening the construction period.)

[0009] Preferably, the driving assembly includes a driving device, a load-bearing gear and a driving gear, the load-bearing gear and the driving gear are both engaged with the ring gear, the load-bearing gear is used to support the ring gear, the driving device is engaged with the driving gear, and the driving device is used to drive the driving gear to rotate, thereby driving the ring gear to rotate.

[0010] The active gear and the load-bearing gear are separated to achieve the separation of driving and load-bearing functions and improve the overall stability. The load-bearing gear is mainly used to support the ring gear, and reasonably distributes the weight and pressure generated during the flipping process to the load-bearing gear, while the active gear is specifically used to drive the ring gear to rotate. This design of separating load-bearing and driving effectively reduces the burden of a single gear when it is working in both load-bearing and driving, prolongs the service life of the gear and equipment, and reduces the wear and failure rate of the equipment when it is running under heavy load.

[0011] Preferably, the pin teeth of the gear ring are located in the same concentric circle, and the centers of the pin teeth are equidistantly distributed.

[0012] The pin teeth are located in the same concentric circle and are evenly spaced, making the meshing between the gear ring and the drive assembly more uniform and stable. This can avoid uneven load distribution when the gear ring rotates, reduce vibration and friction, and make the entire flipping process smoother and more stable.

[0013] Preferably, the machine body is a barrel-shaped mesh cage structure.

[0014] The machine body is set to a barrel-shaped mesh cage structure. The mesh cage structure reduces the use of unnecessary materials in the solid design while maintaining overall strength and rigidity. Compared with the traditional solid structure, the barrel-shaped mesh cage structure greatly reduces the weight of the machine body, thereby reducing the burden on the drive components, and can effectively reduce the flipping inertia during the flipping process; the air-permeable design of the mesh cage structure allows the operator to directly observe the posture and operation of the PC component during the flipping process, which is convenient for real-time monitoring and operation adjustment, and improves the convenience and safety of operation; the left-handed and right-handed rod systems in the mesh cage structure support each other, effectively reducing the calculated length of the rod, reducing the slenderness ratio, and improving the rigidity of the machine body. This design ensures that the equipment is more stable during the flipping process and is not prone to structural deformation.

[0015] Preferably, the mold table support includes a first lifting device, one end of the first lifting device is fixedly connected to the machine body, the other end of the first lifting device is connected to the support platform, at least one mold table wheel is in contact with the support platform, and the first lifting device is used to drive the support platform to move radially along the machine body.

[0016] The first lifting device can drive the supporting platform to move radially along the machine body, so that the mold table can be adjusted in height as needed, ensuring that the upper and lower mold tables can be the same height and longitudinal axis as the mold tables on the production line, which is convenient for moving the PC components into the turning machine. At the same time, the mold table bracket can clamp the PC components from two directions, so that the turning machine can adapt to PC components of different sizes and thicknesses, and has stronger stability when turning.

[0017] Preferably, the mold platform walking wheels include mold platform walking driving wheels and mold platform walking driven wheels, and the mold platform walking driving wheels and the mold platform walking driven wheels have the same height.

[0018] The mold platform's driving wheel and driven wheel are at the same height, ensuring that the mold platform always remains horizontal during its movement in the flip machine. This design avoids the tilt or shake of the mold platform due to inconsistent wheel heights, ensuring that the flipping and movement of the PC components are smoother and more stable; setting the mold platform's driving wheel and driven wheel at the same height can also ensure that the mold platform's wheels are at the same height as the production line system's wheels, so that the mold platform's force pattern is not changed during assembly line operation, and the equipment is more durable.

[0019] Preferably, it also includes a guiding and limiting supporting device, which includes a plurality of limiting blocks and a plurality of supporting blocks, wherein the limiting blocks are higher than the supporting blocks, and the limiting blocks are used to ensure that the supporting platform can only move radially along the machine body within the range surrounded by the limiting blocks; when the first lifting device is lowered, the supporting blocks are used to support the supporting platform.

[0020] The limit blocks enclose a fixed moving area, ensuring that the support platform can only move axially within this range along the body. This design effectively prevents the support platform from deviating or exceeding the specified range during operation, improving the accuracy and safety of the operation; the limit blocks limit the movement of the support platform, avoiding the risk of instability or sliding of the platform when carrying PC components, especially during the flipping process, effectively reducing the occurrence of accidents and ensuring the stability and safety of the equipment at work; when the first lifting device retracts, the support block can automatically support the support platform, reducing the load on the lifting device. This design not only extends the service life of the lifting device, but also provides additional support when the platform is in a lower position, improving the overall load-bearing capacity of the equipment.

[0021] Preferably, it also includes a relatively arranged lateral limit support device, the lateral limit support device includes a second lifting device, one end of the second lifting device is fixedly connected to the machine body, and the other end of the second lifting device is connected to the support limit platform, the second lifting device is used to drive the support limit platform to move radially along the machine body, and the support limit platform is used to clamp the mold table.

[0022] The support and limit platform is used to clamp the mold table to ensure that the mold table remains fixed during the flipping process and will not move due to inertia or external forces. This stable clamping design greatly reduces the risk of the mold table sliding or tilting during the flipping process, ensuring the stability of the PC component during flipping; the second lifting device can move along the radial direction of the machine body, so that the support and limit platform can be flexibly adjusted according to PC components of different sizes and shapes. This can adapt to a variety of working conditions and improve the versatility and applicability of the flip machine; by clamping the mold table with the support and limit platform, it can provide additional support during the flipping process, reduce the impact force on the mold table during flipping, and reduce the potential risk of accidents caused by instability during the flipping process.

[0023] Preferably, the lateral limit support device further comprises a protective tube and a supporting tube, the protective tube is sleeved on the second lifting device, the supporting tube is sleeved on the protective tube, and the supporting tube is fixedly connected to the support limit platform.

[0024] The design of the casing and support tube provides additional support, reduces the lateral shaking and deformation of the second lifting device, and ensures stability during operation. This structure enhances the rigidity of the entire equipment during the flipping process and further improves safety; the casing can effectively prevent the external environment from interfering with the second lifting device and avoid the intrusion of dust, dirt or other objects. This protective design extends the service life of the equipment and reduces maintenance costs.

[0025] Preferably, the lateral limit support device also includes a second limit block, which is installed on the side of the support limit platform away from the second lifting device, and when the second lifting device abuts against the mold platform, the second limit block abuts against the PC component between the mold platform.

[0026] The second limit block abuts against the PC component to accurately position the PC component, ensuring that the component is in the correct position when flipping. During the flipping process, the second limit block can effectively prevent the PC component from accidentally slipping, reducing safety hazards caused by unstable mold platforms or improper operation, and ensuring the safety of operators.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. The PC component turning machine provided by the present invention can realize the in-situ turning of the PC component by connecting the driving assembly with the gear ring, and the gear ring drives the entire machine body to rotate. Compared with the traditional method of lifting the mold table and then turning it, the operation is simpler, the turning time is saved, and the production efficiency is improved;

[0029] 2. The PC component turning machine provided by the present invention has a turning process that is mechanically realized on the ground, and does not require a crane to lift the mold platform in the air to turn it over, which greatly reduces the turning inertia, has low operating difficulty, reduces the danger of operation, and reduces the potential risk of accidents during the lifting process;

[0030] 3. The PC component turning machine provided by the present invention has a lower reliance on workshop height and lifting capacity, and is suitable for various production environments. Especially in workshops with limited space, there is no need to increase the workshop height or expand lifting equipment, saving infrastructure costs;

[0031] 4. The PC component turning machine provided by the present invention is designed with a retractable mold platform bracket. When in use, the height of the mold platform can be adjusted to be consistent with the height of the mold platform of the previous process of the production line, so that the PC component can be quickly moved into the PC component turning machine. After the PC component is moved into place, the retractable mold platform bracket can stably clamp the PC component to ensure the subsequent safe turning of the PC component. The PC component turning machine is provided with mold platforms on the upper and lower sides of the PC component, which can adapt to both single-sided PC components and double-sided PC components, and has a wider range of applications. Compared with the traditional method of lifting the mold platform and then turning it over, the PC component can be turned over in situ. After the casting of the A side of the PC component is completed, it can be directly turned over in situ to start the casting of the B side, without disrupting the construction rhythm of the factory assembly line, improving the construction efficiency and quality, and shortening the construction period.

[0050] Example 1

[0051] like Figure 1-Figure 3 As shown, this embodiment provides a PC component turning machine, which can be used to turn over PC components in situ during factory assembly production in a workshop, without having to lift the mold table in the air and rotate it as in the traditional turning method.

[0052] The present embodiment provides a PC component turning machine, comprising a driving assembly 1, two gear rings 2 and at least two die tables 3, wherein the driving assembly 1 is connected to the gear rings 2 in a transmission manner, and the driving assembly 1 is used to drive the gear rings 2 to rotate, and a machine body 4 is arranged between the two gear rings 2, and the gear rings 2 can drive the machine body 4 to rotate together; a die table bracket 5 is installed on the machine body 4, and the die table brackets 5 are arranged relatively, and the die table brackets 5 can be extended and retracted along the radial direction of the machine body 4; a die table running wheel 6 is arranged on one side of the die table bracket 5 close to the axis of the machine body 4, and the die table running wheel 6 is in contact with the die table 3, and the die table running wheel 6 is used to guide at least one die table 3 to move along the axial direction of the machine body 4.

[0053] Specifically, Figure 1 , Figure 2 As shown, the body 4 can be a barrel-shaped mesh cage structure, that is, the overall shape of the body 4 is similar to a three-dimensional cylinder or barrel; the main body of the structure is composed of left-handed rods and right-handed rods that are mutually oblique, similar to a cage or grid-like frame. These left-handed rods and right-handed rods can be made of metal, composite materials and other materials with high strength and durability, and they can be tightly connected by welding or other means to form a stable whole; the barrel diameter of the body 4 can match the diameter of the left and right gear rings 2, and the body 4 can be fixedly connected to the gear rings 2 or set as an integral structure. The gear ring 2 can be formed by machining thick steel plates. In the initial state, the upper die table 3 can be fixed to the frame by a safety locking device (such as a mechanical lock, a hydraulic lock or an iron chain to prevent the die table 3 from falling off).

[0054] The body 4 is set to a barrel-shaped mesh cage structure. The mesh cage structure reduces the use of unnecessary materials in the solid design while maintaining the overall strength and rigidity. Compared with the traditional solid structure, the barrel-shaped mesh cage structure greatly reduces the weight of the body 4, thereby reducing the burden on the drive assembly 1, and can effectively reduce the flipping inertia during the flipping process; the air-permeable design of the mesh cage structure allows the operator to directly observe the posture and operation of the PC component 100 during the flipping process, which is convenient for real-time monitoring and operation adjustment, and improves the convenience and safety of operation; the left-handed and right-handed rod systems in the mesh cage structure support each other, effectively reducing the calculated length of the rod, reducing the slenderness ratio, and improving the rigidity of the body 4. This design ensures that the equipment is more stable during the flipping process and is not prone to structural deformation.

[0055] Furthermore, the pin teeth of the gear ring 2 are located in the same concentric circle, that is, Figure 1The diameters of the two gear rings 2 shown are basically the same, and the pin teeth are evenly spaced, that is, the center points of all the pin teeth on the gear ring 2 or the gear are evenly arranged at the same angle interval in the circumferential direction. This means that the center distance (angle) between each adjacent pin tooth is exactly the same, thus forming a regular, symmetrical geometric distribution on the entire gear ring 2 or the gear. The teeth are located on the same concentric circle and are evenly spaced, making the meshing between the gear ring 2 and the drive assembly 1 more uniform and stable. This can avoid uneven load distribution when the gear ring 2 rotates, reduce vibration and friction, and make the entire flipping process smoother and more stable.

[0056] Further Figure 4 As shown, the driving assembly 1 includes a driving device 11, a load-bearing gear 12 and a driving gear 13. The load-bearing gear 12 and the driving gear 13 are both meshed with the ring gear 2. The load-bearing gear 12 is used to support the ring gear 2. Specifically, the load-bearing gear 12 can be arranged symmetrically with the vertical axis of the ring gear 2 as the central axis. The load-bearing gear 12 has a centripetal supporting effect and can prevent the turning machine from being displaced, thereby playing a role in supporting all the upper loads; the driving device 11 is meshed with the driving gear 13, and the driving device 11 is used to drive the driving gear 13 to rotate. The driving device 11 can use a hydraulic motor or an electric motor to drive the ring gear 2 to rotate.

[0057] The active gear 13 and the load-bearing gear 12 are separated to achieve the separation of driving and load-bearing functions and improve the overall stability. The load-bearing gear 12 is mainly used to support the ring gear 2, and reasonably distributes the weight and pressure generated during the flipping process to the load-bearing gear 12, while the active gear 13 is specifically used to drive the ring gear 2 to rotate. This design of separating load-bearing and driving effectively reduces the burden of a single gear when it is working simultaneously in load-bearing and driving, extends the service life of the gear and equipment, and reduces the wear and failure rate of the equipment when running under heavy loads. When in use, the driving device 11 drives the active gear 13 to rotate, and the active gear 13 further drives the ring gear 2 to rotate, while the load-bearing gear 12 supports its load and rotates together with the ring gear 2 while ensuring the stable operation of the ring gear 2.

[0058] Further, such as Figure 1-Figure 4 As shown, the die table support 5 includes a first lifting device 51, one end of the first lifting device 51 is fixedly connected to the machine body 4, the other end of the first lifting device 51 is connected to the support platform 52, at least one die table wheel 6 is in contact with the support platform 52, and the first lifting device 51 is used to drive the support platform 52 to move along the radial direction of the machine body 4. Specifically, the first lifting device 51 can use a hydraulic jack.

[0059] The first lifting device 51 can drive the support platform 52 to move along the radial direction of the machine body 4, so that the mold table 3 can be adjusted in height as needed, ensuring that the upper and lower mold tables 3 can have the same height and longitudinal axis as the mold tables 3 on the production line, which is convenient for the PC component 100 to be moved into the turning machine. At the same time, the mold table bracket 5 can be adjusted from Figure 4 The PC component 100 is clamped in the upper and lower directions, so that the flipping machine can adapt to PC components 100 of different sizes and thicknesses, and the stability during flipping is stronger.

[0060] Furthermore, the mold platform wheel 6 includes a mold platform driving wheel 61 and a mold platform driven wheel 62, and the mold platform driving wheel 61 and the mold platform driven wheel 62 have the same height. The mold platform driving wheel 61 and the driven wheel are in the same height, ensuring that the mold platform 3 always remains horizontal during the movement process in the turning machine. This design avoids the tilting or shaking of the mold platform 3 due to the inconsistent wheel height, ensuring that the turning and movement of the PC component 100 is more stable and smooth;

[0061] Setting the mold platform driving wheel 61 and the driven wheel to be at the same height can also ensure that the mold platform walking wheel 6 is at the same height as the production line system walking wheel. The force mode of the mold platform 3 is not changed during assembly line operation, and the equipment durability is better.

[0062] Furthermore, the mold platform travel driving wheel 61 can be connected to a hydraulic motor or an electric motor, and the mold platform travel driving wheel 61 is driven by the motor to move, so that the mold platform can be directly moved into the machine body 4 through the production line system wheel during assembly line operation.

[0063] Furthermore, the PC component turning machine provided in this embodiment also includes a guide limit support device 7, which includes a plurality of limit blocks 71 and a plurality of support blocks 72. The limit blocks 71 are higher than the support blocks 72. The limit blocks 71 are used to ensure that the support platform 52 can only move radially along the machine body 4 within the range surrounded by the limit blocks 71; when the first lifting device 51 is lowered, the support blocks 72 are used to support the support platform 52.

[0064] Specifically, the limit block 71 can be as follows Figure 4 As shown, a fixed moving area is formed to ensure that the support platform 52 can only move axially within the range along the body 4. This design effectively prevents the support platform 52 from deviating or exceeding the specified range during operation, thereby improving the accuracy and safety of the operation;

[0065] The limit block 71 limits the movement of the support platform 52, thereby avoiding the risk of the platform becoming unstable or sliding when carrying the PC component 100, especially during the flipping process, effectively reducing the occurrence of accidents and ensuring the stability and safety of the equipment during operation;

[0066] When the first lifting device 51 is retracted (for example Figure 4 The support block 72 can automatically support the support platform 52, reducing the load on the lifting device. This design not only extends the service life of the lifting device, but also provides additional support when the platform is in a lower position, thereby improving the overall load-bearing capacity of the equipment.

[0067] The PC component turning machine provided in this embodiment is connected to the driving assembly 1 and the ring gear 2 through transmission, and the ring gear 2 drives the entire machine body 4 to rotate, so as to realize the in-situ turning of the PC component 100. Compared with the traditional method of lifting the mold platform 3 and then turning it over, the operation is simpler, the turning time is saved, and the production efficiency is improved; the PC component turning machine provided by the present invention, because the turning process is realized mechanically on the ground, does not require a crane to lift the mold platform 3 in the air to turn it over, greatly reduces the turning inertia, has low operating difficulty, reduces the danger of operation, and reduces the potential accident risk during the lifting process; the design of the PC component turning machine provided by the present invention reduces the dependence on the workshop height and lifting capacity, and is suitable for various production environments. Especially in workshops with limited space, there is no need to increase the workshop height or expand lifting equipment, saving infrastructure costs; by designing a retractable mold platform bracket 5, the height of the mold platform 3 can be adjusted to be consistent with the height of the mold platform 3 in the previous process of the production line during use, so that the PC component 100 can be quickly moved into the PC component flipping machine. After the PC component 100 is moved into place, the retractable mold platform bracket 5 can stably clamp the PC component 100 to ensure the subsequent safe flipping of the PC component 100.

[0068] The PC component turning machine is provided with mold platforms 3 on both the upper and lower surfaces of the PC component 100, which can adapt to both single-sided PC components 100 and double-sided PC components 100, and has a wider scope of application; compared with the traditional method of lifting the mold platform 3 and then turning it over, it can realize the in-situ turning of the PC component 100. After the casting of the A surface of the PC component 100 is completed, it can be directly turned over in situ to start the casting of the B surface, without disrupting the construction rhythm of the factory assembly line, thereby improving the construction efficiency and quality and shortening the construction period.

[0069] The PC component turning machine provided in this embodiment solves the problem that large-scale cavity PC components (such as large-scale box grid plane structures with a thickness of 600-800 mm, a double-sided cavity composite plate structure, and a segment width of 5-6 m) are difficult to turn over; using the PC component turning machine does not increase the local height of the workshop, and the workshop layout is more reasonable, which solves the problem of factory production of PC components and promotes technological progress in the construction industry.

[0071] On the basis of Example 1, Figure 5-Figure 10As shown, the PC component turning machine provided in this embodiment also includes a lateral limit support device 8 that is relatively arranged. The lateral limit support device 8 includes a second lifting device 81. One end of the second lifting device 81 is fixedly connected to the machine body 4, and the other end of the second lifting device 81 is connected to the support limit platform 82. The second lifting device 81 is used to drive the support limit platform 82 to move radially along the machine body 4, and the support limit platform 82 is used to clamp the mold table 3.

[0072] The support and limit platform 82 is used to clamp the mold platform 3, ensuring that the mold platform 3 remains fixed during the flipping process and does not move due to inertia or external forces. This stable clamping design greatly reduces the risk of the mold platform 3 sliding or tilting during the flipping process, ensuring the stability of the PC component 100 during flipping;

[0073] The second lifting device 81 can move along the radial direction of the machine body 4, so that the support and limiting platform 82 can be flexibly adjusted according to PC components 100 of different sizes and shapes. This can adapt to various working conditions and improve the versatility and applicability of the turnover machine;

[0074] By supporting the clamping of the mold platform 3 by the limit platform 82, additional support can be provided during the flipping process, reducing the impact force on the mold platform 3 during flipping, and reducing the potential risk of accidents caused by instability during the flipping process.

[0075] Furthermore, the lateral limit support device 8 also includes a protective tube 83 and a supporting tube 84 . The protective tube 83 is sleeved on the second lifting device 81 , and the supporting tube 84 is sleeved on the protective tube 83 . The supporting tube 84 is fixedly connected to the support limit platform 82 .

[0076] The design of the protective tube 83 and the supporting tube 84 provides additional support, reduces the lateral shaking and deformation of the second lifting device 81, and ensures stability during operation. This structure enhances the rigidity of the entire device during the flipping process and further improves safety; the protective tube 83 can effectively prevent the external environment from interfering with the second lifting device 81 and avoid the intrusion of dust, dirt or other objects. This protective design extends the service life of the equipment and reduces maintenance costs.

[0077] Furthermore, the lateral limit support device 8 also includes a second limit block 85, which is installed on the side of the support limit platform 82 away from the second lifting device 81, and when the second lifting device 81 abuts against the mold platform 3, the second limit block 85 abuts against the PC component 100 between the mold platform 3.

[0078] The second limit block 85 abuts against the PC component 100 to accurately position the PC component 100, ensuring that the component is in the correct position when flipping. During the flipping process, the second limit block 85 can effectively prevent the PC component 100 from accidentally sliding off, reducing the safety hazards caused by the instability of the mold platform 3 or improper operation, and ensuring the safety of the operator.

[0079] In order to achieve the degree of automation of the PC component turning machine, an infrared rangefinder can also be set at the center position of the PC component (for example, on the mold table) to measure the precise position of the PC component in real time. In order to ensure the accuracy of the distance measurement, multiple infrared rangefinders can be set to monitor the displacement and position in different directions respectively. The infrared rangefinder is connected to the central control center of the production line. The central control center will receive the real-time data of the rangefinder and analyze the deviation between the actual position of the PC component and the predetermined position. The PC component is automatically tracked and positioned through central control. When the rangefinder detects that the position of the PC component deviates from the predetermined center position, the central control system will automatically calculate the direction and distance that need to be adjusted. The driving components and positioning system of the turning machine can be equipped with servo motors or stepper motors. According to the instructions of the central control center, the mold table can be fine-tuned to achieve precise centering of the PC component. Unmanned on-site control can be realized, improving the working environment of industrial workers.

[0080] When in use, the PC component turning machine, as an important part of the PC component production line, should match the complete production line process. Located downstream of the curing kiln station, equivalent to the length of one station, the components are cured and output from the curing kiln, passing through the PC component turning machine station, and the mold table wheel 6 is adjusted in advance to be consistent with the production line system wheel height. The double-layered panels that need to be turned over enter the turning machine for turning; and the single-layer panels do not need to be turned over, and directly pass through the PC component turning machine to enter the next process, without disrupting the flow rhythm, so that the entire production line chain is not interrupted.

[0081] like Figure 5-Figure 10 The figure shows a complete PC component flipping process. Figure 5 As shown, at this time, the PC component turning machine is in the initial state, the lower die table 3 supports the PC component 100, the lower die table 3 is supported by the first lifting device 51, the lateral limit support devices 8 on the left and right sides are not extended, the upper die table 3 is not in contact with the PC component 100, and the upper support platform 52 is in contact with the support block 72;

[0082] like Figure 6 The figure shows the PC component turning machine in the state of waiting to turn over, at this time, the upper die table 3 is pressed down and clamps the PC component 100 together with the lower die table 3, the lateral limit support devices 8 on the left and right sides are extended, the support limit platform 82 is in contact with the upper and lower die tables 3, and the second limit block 85 is in contact with the PC component 100.

[0083] like Figure 7 , Figure 8 The figure shows a schematic diagram of the PC component turning machine flipped 90°. At this time, the PC component 100 is basically in a vertical state, and the lateral limit support device 8 plays a good supporting and limiting role on the upper and lower mold platforms 3 and the PC component 100.

[0084] like Fig. 9 The figure shows a schematic diagram of the PC component turning machine turning 180°. At this time, the upper and lower die tables 3 and the lateral limit support device 8 still lock the PC component 100.

[0085] like Fig.10 The figure shows a schematic diagram of the state of the PC component turning machine after turning over. At this time, the lateral limit support devices 8 on the left and right sides are retracted, and the mold platform 3 located at the upper part is retracted (for example, lifted by a chain), and the turning of the PC component is completed. At this time, the mold platform 3 located at the lower part can be driven out of the machine body 4 by the mold platform walking driving wheel 61 to enter the next process.

[0086] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
