Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a PC component turning machine. Background Technology

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

[0003] Currently, most prefabricated components are manufactured in factories using assembly lines. These components boast high strength and stable quality. The three-shift assembly line operation significantly shortens construction time, and much of the work, previously done at heights, is now automated and intelligent, ensuring safety and aligning with green, energy-saving, and environmentally friendly principles. Prefabricated concrete buildings have become the most common form of prefabricated construction in my country and represent one of the main directions for the development of my country's building industrialization.

[0004] In industrial production, precast concrete (PC) components are commonly divided into single-sided and double-sided types. Single-sided components involve a relatively simple process: marking on a mold, placing the reinforcing steel truss, pouring, vibrating, curing in a kiln, testing, demolding, and shipping. Double-sided hollow precast components are precast in two stages, A and B. In addition to the same precasting process as single-sided components, each side undergoes an extra turning process. A crucial step in the workshop precasting of double-sided hollow precast components is turning them over and pouring the other side (B side). Currently, the standard dimensions of the production line are 9m × 4m, the maximum width of the component is 3.5m, and the weight is less than 100kN.

[0005] However, the existing method of turning over PC components involves using a gantry crane to lift the mold table in the air and then rotating it, which places high demands on the workshop's lifting capacity and space height. In particular, it is difficult to turn over PC components that are large in size and weight. Moreover, the method of lifting the mold table in the air and then rotating it results in a large inertia and is difficult to operate. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of existing technologies, such as difficulty in flipping PC components, high requirements for workshops, and high operational difficulty, and to provide a PC component flipping machine.

[0007] In a first aspect, the present invention provides a PC component flipping machine, comprising a drive assembly, two gear rings, and at least two mold tables. The drive assembly is pulsatorically connected to the gear rings and is used to drive the gear rings to rotate. A machine body is disposed between the two gear rings, and the gear rings can drive the machine body to rotate together. A mold table support is mounted on the machine body, and the mold table supports are disposed opposite to each other. The mold table supports are capable of radial extension and retraction along the machine body. A mold table wheel is disposed on the side of the mold table support near the axis of the machine body. The mold table wheel contacts the mold table and is used to guide at least one mold table to move axially along the machine body.

[0008] The PC component flipping machine provided by this invention, through the transmission connection between the drive component and the gear ring, enables the entire machine body to rotate, achieving in-situ flipping of PC components. Compared with the traditional method of lifting the mold table before flipping, the operation is simpler, saving flipping time and improving production efficiency. Since the flipping process is achieved mechanically on the ground, the PC component flipping machine of this invention does not require a crane to lift the mold table in the air for flipping, greatly reducing flipping inertia, lowering operational difficulty, reducing operational risks, and minimizing potential accident risks during hoisting. The design of the PC component flipping machine of this invention reduces dependence on workshop height and lifting capacity, making it suitable for various production environments. Especially in space-constrained workshops, it eliminates the need to increase workshop height or expand lifting equipment, saving infrastructure costs. By designing a telescopic mold table support, the mold table height can be adjusted to match the mold table height of the previous process on the production line, facilitating the rapid movement of PC components into the PC component flipping machine. Once the PC component is in place, the telescopic mold table support stably clamps the PC component, ensuring safe subsequent flipping. This PC component turning machine has mold platforms on both the top and bottom sides of the PC component, making it suitable for both single-sided and double-sided PC components, thus broadening its application range. Compared to the traditional method of lifting the mold platform before turning, it enables in-situ turning of the PC component. After the A side of the PC component is poured, it can be directly turned in place for the B side to be poured, without disrupting the factory's production line rhythm, improving construction efficiency and quality, and shortening the construction period.

[0009] Preferably, the drive assembly includes a drive device, a load-bearing gear, and a drive gear. Both the load-bearing gear and the drive gear mesh with the gear ring. The load-bearing gear supports the gear ring. The drive device meshes with the drive gear and drives the drive gear to rotate, thereby causing the gear ring to rotate.

[0010] By separating the drive gear and the load-bearing gear, the driving and load-bearing functions are separated, improving overall stability. The load-bearing gear mainly supports the gear ring, distributing the weight and pressure generated during rotation reasonably onto it, while the drive gear is dedicated to driving the gear ring's rotation. This design, separating load-bearing and driving functions, effectively reduces the burden on a single gear when it is simultaneously working in both load-bearing and driving modes, extending the service life of the gears and equipment, and reducing wear and failure rates under heavy loads.

[0011] Preferably, the pins of the gear ring are located on the same concentric circle, and the centers of the pins are equidistantly distributed.

[0012] The pins are located on the same concentric circle and are evenly distributed, making the meshing between the gear ring and the drive assembly more uniform and stable. This avoids uneven load distribution during gear ring rotation, reduces vibration and friction, and makes the entire rotation process smoother and more stable.

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

[0014] The machine body is designed with a barrel-shaped wire mesh cage structure. This cage structure reduces unnecessary material usage compared to a solid design while maintaining overall strength and rigidity. Compared to traditional solid structures, the barrel-shaped wire mesh cage structure significantly reduces the weight of the machine body, thereby reducing the burden on the drive components and effectively reducing tilting inertia during the tilting process. The open design of the wire mesh cage structure allows operators to directly observe the attitude and operation of the PC components during the tilting process, facilitating real-time monitoring and operational adjustments, thus improving operational convenience and safety. The left-hand and right-hand spiral rods in the wire mesh cage structure support each other, effectively reducing the calculated length of the rods, lowering the slenderness ratio, and improving the rigidity of the machine body. This design ensures greater stability of the equipment during tilting and reduces the likelihood of structural deformation.

[0015] Preferably, the mold platform support includes a first lifting device, one end of which is fixedly connected to the machine body, the other end of which is connected to a support platform, at least one of the mold platform wheels 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 support platform to move radially along the machine body, so that the mold table can be adjusted in height as needed. This ensures that the upper and lower mold tables are the same as the mold tables on the production line in terms of height and longitudinal axis, making it easier for PC components to be moved into the flipping machine. At the same time, the mold table support can clamp the PC components from two directions, so that the flipping machine can adapt to PC components of different sizes and thicknesses, and has stronger stability during flipping.

[0017] Preferably, the mold table wheels include a driving wheel and a driven wheel, and the driving wheel and the driven wheel are at the same height.

[0018] The drive and driven wheels of the mold table are at the same height, ensuring that the mold table remains horizontal throughout its movement within the tilting machine. This design prevents tilting or wobbling caused by inconsistent wheel heights, ensuring smoother and more stable flipping and movement of PC components. Furthermore, ensuring that the drive and driven wheels are at the same height also guarantees that the mold table wheels are aligned with the production line system wheels, maintaining the same force distribution on the mold table during assembly line operations and improving equipment durability.

[0019] Preferably, it further includes a guide and limit support device, which includes a plurality of limit blocks and a plurality of support blocks. The height of the limit blocks is higher than that of the support blocks. The limit blocks are used to ensure that the support platform can only move radially along the body within the range enclosed by the limit blocks. When the first lifting device is lowered, the support blocks are used to support the support platform.

[0020] The limiting blocks form a fixed moving area, ensuring that the support platform can only move along the machine's axis within this range. This design effectively prevents the support platform from deviating or exceeding the specified range during operation, improving operational accuracy and safety. By restricting the movement of the support platform, the limiting blocks avoid the risk of instability or slippage when the platform is carrying PC components, especially during tilting, effectively reducing accidents and ensuring the stability and safety of the equipment during operation. When the first lifting device retracts, the support blocks 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 further includes a lateral limiting support device arranged opposite to the machine body. The lateral limiting 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 supporting limiting platform. The second lifting device is used to drive the supporting limiting platform to move radially along the machine body. The supporting limiting platform is used to clamp the mold table.

[0022] The support and limiting platform is used to clamp the mold table, ensuring that it 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 mold table slippage or tilting during flipping, ensuring the stability of the PC component during flipping. The second lifting device can move radially along the machine body, allowing the support and limiting platform to be flexibly adjusted according to PC components of different sizes and shapes. This adapts to various working conditions, improving the versatility and applicability of the flipping machine. By clamping the mold table with the support and limiting platform, additional support is provided during flipping, reducing the impact force on the mold table and minimizing the potential accident risk caused by instability during flipping.

[0023] Preferably, the lateral limiting support device further includes a protective sleeve and a support sleeve, the protective sleeve being sleeved on the second lifting device, the support sleeve being sleeved on the protective sleeve, and the support sleeve being fixedly connected to the supporting limiting platform.

[0024] The design of the protective sleeve and support sleeve provides additional support, reducing lateral sway and deformation of the second lifting device and ensuring stability during operation. This structure enhances the rigidity of the entire device during tilting, further improving safety; the protective sleeve effectively prevents external environmental interference with the second lifting device, avoiding 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 limiting support device further includes a second limiting block, which is installed on the side of the supporting limiting platform away from the second lifting device. When the second lifting device abuts against the mold table, the PC component between the second limiting block and the mold table abuts against it.

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

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] 1. The PC component flipping machine provided by this invention, through the transmission connection between the drive component and the gear ring, enables the entire machine body to rotate, thereby achieving in-situ flipping of PC components. Compared with the traditional method of lifting the mold table before flipping, the operation is simpler, saving flipping time and improving production efficiency;

[0029] 2. The PC component turning machine provided by the present invention achieves the turning process mechanically on the ground, without the need for a crane to lift the mold table in the air for turning, which greatly reduces the turning inertia, makes operation easier, reduces the danger of operation, and reduces the potential accident risk during hoisting.

[0030] 3. The PC component tilting machine provided by this invention reduces the dependence on workshop height and lifting capacity, making it suitable for various production environments. Especially in space-constrained workshops, it eliminates the need to increase workshop height or expand lifting equipment, saving on infrastructure costs.

[0031] 4. The PC component turning machine provided by this invention features a telescopic mold support. During use, the mold height can be adjusted to match the height of the mold in the previous process of the production line, facilitating the rapid movement of PC components into the turning machine. Once in place, the telescopic mold support stably clamps the PC component, ensuring safe turning of the component. This turning machine has molds on both the top and bottom sides of the PC component, adapting to both single-sided and double-sided components, thus broadening its applicability. Compared to the traditional method of lifting the mold before turning, this method enables in-situ turning of the PC component. After the A-side of the PC component is poured, it can be directly turned in place for the B-side pouring, without disrupting the factory's production line rhythm, improving construction efficiency and quality, and shortening the construction period.

Detailed Implementation

[0044] The present invention will now be described in further detail with reference to specific embodiments. However, this should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0045] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of the present invention is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the product / equipment / device is typically placed during use. These terms are merely for the purpose of facilitating the description of the present invention or simplifying the description in specific embodiments, enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a particular device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on the present invention.

[0046] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," and "parallel" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, or parallel, but rather that it can be slightly tilted or have a deviation. For example, "horizontal" merely means that its direction is more horizontal relative to "vertical," not that the structure must be completely horizontal, but that it can be slightly tilted. Alternatively, it can be simplified to mean that the corresponding device / component / element, when set in a "horizontal," "vertical," "suspended," or "parallel" direction, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0047] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing between identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0048] Furthermore, in the description of the embodiments of the present invention, "several", "more than", and "a number of" represent at least two. The number can be any number, such as 2, 3, 4, 5, 6, 7, 8, or 9, and can even exceed nine.

[0049] Furthermore, in the description of the technical solution of this invention, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "provided with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0050] Example 1

[0051] like Figures 1-3 As shown, this embodiment provides a PC component flipping machine, which can be used to flip PC components in place during factory assembly line production in a workshop, instead of using the traditional flipping method of lifting the mold table in the air for rotation and flipping.

[0052] This embodiment provides a PC component flipping machine, including a drive assembly 1, two gear rings 2, and at least two mold tables 3. The drive assembly 1 is connected to the gear rings 2 for transmission and is used to drive the gear rings 2 to rotate. 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 mold table support 5 is installed on the machine body 4. The mold table supports 5 are arranged opposite each other and can extend and retract radially along the machine body 4. A mold table wheel 6 is arranged on the side of the mold table support 5 near the axis of the machine body 4. The mold table wheel 6 contacts the mold table 3 and is used to guide at least one mold table 3 to move axially along the machine body 4.

[0053] Specifically, such as Figure 1 , Figure 2 As shown, the body 4 can be a barrel-shaped cage structure, meaning the overall shape of the body 4 resembles a three-dimensional cylinder or barrel. The main body of the structure is composed of left-handed and right-handed rod systems that intersect obliquely, resembling a cage or a mesh frame. These left-handed and right-handed rod systems can be made of high-strength and durable materials such as metals and composite materials, and they may be tightly connected by welding or other methods to form a stable whole. The diameter of the body 4 can match the diameter of the two toothed rings 2, and the body 4 can be fixedly connected to the toothed rings 2 or set as an integral structure. The toothed rings 2 can be made of thick steel plates and machined. In the initial state, the upper mold platform 3 can be fixed to the frame by a safety locking device (such as a mechanical lock, hydraulic lock, or iron chain to prevent the mold platform 3 from falling off).

[0054] The body 4 is designed as a barrel-shaped wire mesh cage structure. This cage structure reduces unnecessary material usage compared to a solid design while maintaining overall strength and rigidity. Compared to traditional solid structures, the barrel-shaped wire mesh cage structure significantly reduces the weight of body 4, thereby lessening the burden on the drive assembly 1 and effectively reducing tilting inertia during the tilting process. The open design of the wire mesh cage structure allows operators to directly observe the attitude and operation of the PC component 100 during tilting, facilitating real-time monitoring and operational adjustments, thus improving operational convenience and safety. The left-hand and right-hand rotating rods in the wire mesh cage structure support each other, effectively reducing the calculated length of the rods, lowering the slenderness ratio, and increasing the rigidity of body 4. This design ensures greater stability of the equipment during tilting and reduces the likelihood of structural deformation.

[0055] Furthermore, the pin teeth of gear ring 2 are located on the same concentric circle, i.e., as shown in the image. Figure 1The two gear rings 2 shown have essentially the same diameter, and the centers of the pins are equidistantly distributed, meaning that the center points of all the pins on the gear ring 2 or gear are evenly spaced at the same angle along the circumference. This implies that the center distance (angle) between each adjacent pin is completely equal, thus forming a regular and symmetrical geometric distribution across the entire gear ring 2 or gear. The teeth being located on the same concentric circle and equidistantly distributed makes the meshing between the gear ring 2 and the drive assembly 1 more uniform and stable. This avoids uneven load distribution during the rotation of the gear ring 2, reduces vibration and friction, and makes the entire rotation process smoother and more stable.

[0056] Further such as Figure 4 As shown, the drive assembly 1 includes a drive device 11, a load-bearing gear 12, and a drive gear 13. Both the load-bearing gear 12 and the drive gear 13 mesh with the gear ring 2. The load-bearing gear 12 is used to support the gear ring 2. Specifically, the load-bearing gear 12 can be arranged symmetrically about the vertical axis of the gear ring 2. The load-bearing gear 12 has a supporting centripetal function and can prevent the tilting machine from deviating, thus supporting the entire upper load. The drive device 11 meshes with the drive gear 13 and is used to drive the drive gear 13 to rotate. The drive device 11 can use a hydraulic motor or an electric motor, thereby driving the gear ring 2 to rotate.

[0057] By separating the drive gear 13 and the load-bearing gear 12, the driving and load-bearing functions are separated, improving overall stability. The load-bearing gear 12 is mainly used to support the gear ring 2, and the weight and pressure generated during the rotation process are reasonably distributed to the load-bearing gear 12, while the drive gear 13 is dedicated to driving the gear ring 2 to rotate. This design of separating load-bearing and driving functions effectively reduces the burden on a single gear when it is working in both load-bearing and driving modes simultaneously, extends the service life of the gears and equipment, and reduces wear and failure rate of the equipment under heavy loads. In use, the drive unit 11 drives the drive gear 13 to rotate, and the drive gear 13 further drives the gear ring 2 to rotate, while the load-bearing gear 12 supports the load of the gear ring 2 while ensuring its stable operation and rotates together with the gear ring 2.

[0058] Furthermore, such as Figures 1-4 As shown, the mold platform support 5 includes a first lifting device 51, one end of which is fixedly connected to the machine body 4, and the other end of which is connected to the support platform 52. At least one mold platform wheel 6 is in contact with the support platform 52. The first lifting device 51 is used to drive the support platform 52 to move radially along the machine body 4. Specifically, the first lifting device 51 can be a hydraulic jack.

[0059] The first lifting device 51 can drive the support platform 52 to move radially along 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 are the same in height and longitudinal axis as the mold tables 3 on the production line, which facilitates the movement of the PC component 100 into the flipping machine. At the same time, the mold table support 5 can be moved from the machine body to the machine body. Figure 4 The PC component 100 is clamped in both the upper and lower directions, as shown, so that the flipping machine can adapt to PC components 100 of different sizes and thicknesses, and the stability is stronger when flipping.

[0060] Furthermore, the mold table casters 6 include a driving caster 61 and a driven caster 62, both of which are at the same height. This consistent height ensures that the mold table 3 remains horizontal throughout its movement within the tilting machine. This design prevents tilting or wobbling of the mold table 3 due to inconsistent wheel heights, ensuring smoother and more stable tilting and movement of the PC component 100.

[0061] Setting the driving wheel 61 and driven wheel of the mold table to be at the same height also ensures that the height of the mold table wheel 6 is consistent with that of the production line system wheel, so that the force mode of the mold table 3 is not changed during assembly line operation, and the equipment is more durable.

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

[0063] Furthermore, the PC component flipping machine provided in this embodiment also includes a guide and limit support device 7. The guide and limit support device 7 includes several limit blocks 71 and several support blocks 72. The height of the limit blocks 71 is higher than that of 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 enclosed 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, limit block 71 can be as follows: Figure 4 The design creates a fixed moving area, ensuring that the support platform 52 can only move along the axial direction of the body 4 within this range. This design effectively prevents the support platform 52 from deviating or exceeding the specified range during operation, improving the accuracy and safety of the operation.

[0065] The limiting block 71 restricts the movement of the support platform 52, thus avoiding the risk of instability or slippage of the platform when carrying the PC component 100. Especially during the flipping process, it effectively reduces the occurrence of accidents and ensures the stability and safety of the equipment during operation.

[0066] When the first lifting device 51 retracts (for example) Figure 4 (As shown in the upper part), 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, improving the overall load-bearing capacity of the equipment.

[0067] The PC component turning machine provided in this embodiment, through the transmission connection between the drive component 1 and the gear ring 2, drives the entire machine body 4 to rotate, enabling the PC component 100 to be turned in place. Compared with the traditional method of lifting the mold table 3 before turning, the operation is simpler, saving turning time and improving production efficiency. Since the turning process of the PC component turning machine provided by this invention is achieved mechanically on the ground, there is no need for a crane to lift the mold table 3 in the air for turning, which greatly reduces the turning inertia, reduces the difficulty of operation, reduces the danger of operation, and reduces the potential accident risk during hoisting. The design of the PC component turning machine provided by this invention reduces the dependence 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 height of the workshop or expand the lifting equipment, saving on infrastructure costs. By designing a telescopic mold table support 5, the height of the mold table 3 can be adjusted to match the height of the mold table 3 in the previous process of the production line, which facilitates the rapid movement of the PC component 100 into the PC component flipping machine. After the PC component 100 is moved into place, the telescopic mold table support 5 can stably clamp the PC component 100, ensuring the safe flipping of the PC component 100 in the subsequent process.

[0068] This PC component turning machine has mold tables 3 on both the upper and lower sides of the PC component 100, which can accommodate both single-sided and double-sided PC components 100, thus having a wider range of applications. Compared with the traditional method of lifting the mold table 3 and then turning it over, it can realize the in-situ turning of the PC component 100. After the A side of the PC component 100 is poured, it can be turned over directly in the in-situ for the B side to be poured, without disrupting the factory's production line construction rhythm, improving construction efficiency and quality, and shortening the construction period.

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

[0070] Example 2

[0071] Based on Example 1, such as Figures 5-10As shown, the PC component flipping machine provided in this embodiment also includes a lateral limiting support device 8 arranged opposite to it. The lateral limiting 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 limiting platform 82. The second lifting device 81 is used to drive the support limiting platform 82 to move radially along the machine body 4. The support limiting platform 82 is used to clamp the mold table 3.

[0072] The support and limiting platform 82 is used to clamp the mold table 3, ensuring that the mold table 3 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 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 radially along the machine body 4, allowing the support and limiting platform 82 to be flexibly adjusted according to PC components 100 of different sizes and shapes. This adapts to various working conditions and improves the versatility and applicability of the tilting machine.

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

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

[0076] The design of the protective sleeve 83 and support sleeve 84 provides additional support, reducing lateral sway and deformation of the second lifting device 81 and ensuring stability during operation. This structure enhances the rigidity of the entire device during tilting, further improving safety; the protective sleeve 83 effectively prevents external environmental interference with the second lifting device 81, avoiding 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 limiting support device 8 also includes a second limiting block 85, which is installed on the side of the supporting limiting platform 82 away from the second lifting device 81. When the second lifting device 81 abuts against the mold table 3, the second limiting block 85 abuts against the PC component 100 between the mold table 3 and the mold table 3.

[0078] The second limiting 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 limiting block 85 can effectively prevent the PC component 100 from accidentally slipping off, reducing safety hazards caused by instability of the mold table 3 or improper operation, and ensuring the safety of operators.

[0079] To achieve a high degree of automation in this PC component flipping machine, infrared rangefinders can be installed at the PC component centering position (e.g., on the mold table) to measure the precise position of the PC component in real time. To ensure the accuracy of the distance measurement, multiple infrared rangefinders can be installed to monitor displacement and position in different directions. The infrared rangefinders communicate with the central control center of the production line. The central control center receives real-time data from the rangefinders and analyzes the deviation between the actual position and the predetermined position of the PC component. Through automatic tracking and positioning of the PC component by the central control, when the rangefinder detects that the PC component's position deviates from the predetermined center position, the central control system automatically calculates the direction and distance that need to be adjusted. The drive components and positioning system of the flipping machine can be equipped with servo motors or stepper motors. According to the instructions of the central control center, the mold table is fine-tuned to achieve precise centering of the PC component. This enables unmanned on-site operation and improves the working environment for industrial workers.

[0080] When in use, the PC component turning machine, as an important link in the PC component production line, should be matched with the overall production line process. Located downstream of the curing kiln station, equivalent to one station length, after the components have completed curing, they are output from the curing kiln and pass through the PC component turning machine station. The height of the mold table wheels 6 should be adjusted in advance to match the height of the production line system wheels. Double-layered boards that need to be turned over enter the turning machine for turning; while single-layer boards do not need to be turned over and pass directly through the PC component turning machine to enter the next process, without disrupting the flow rhythm and ensuring that the entire production line chain is uninterrupted.

[0081] like Figures 5-10 This demonstrates a complete PC component flipping process. Specifically, as shown below... Figure 5 As shown, the PC component flipping machine is in its initial state at this time. The lower mold platform 3 supports the PC component 100. At this time, the lower mold platform 3 is supported by the first lifting device 51. The lateral limiting support devices 8 on the left and right sides are not extended. The upper mold platform 3 is not in contact with the PC component 100. The upper support platform 52 is in contact with the support block 72.

[0082] like Figure 6 The image shows the PC component flipping machine in the flipping state. At this time, the upper mold 3 presses down and clamps the PC component 100 together with the lower mold 3. The lateral limiting support devices 8 on the left and right sides extend out, the supporting limiting platform 82 abuts against the upper and lower mold 3, and the second limiting block 85 abuts against the PC component 100.

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

[0084] like Figure 9 The diagram shows the PC component flipping machine in a 180° flipped state. At this time, the upper and lower mold tables 3 and the lateral limiting support device 8 still lock the PC component 100.

[0085] like Figure 10 The diagram shows the state of the PC component flipping machine after flipping. At this time, the lateral limiting support devices 8 on the left and right sides are retracted, and the upper mold table 3 is retracted (for example, by being lifted by a chain). The PC component flipping is completed. At this time, the lower mold table 3 can drive out of the machine body 4 under the drive of the mold table travel drive wheel 61 and enter the next process.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
