Description

Technical Field

[0001] This utility model relates to the field of flipping technology for slotted parts, and more specifically, to a flipping machine for slotted parts. Background Technology

[0002] In the field of urban underground expressway construction, ultra-large cross-section shield tunnels have become an important construction method due to their ability to achieve intensive layout and multi-functional utilization of underground space. As a standard configuration of the internal structure of the tunnel, the prefabrication and shipment process of precast concrete subway tunnel "gate components" has a key impact on the efficiency and quality of tunnel construction. From concrete pouring to final shipment, the gate components need to go through several key processes: first, steam curing is used to accelerate the development of concrete strength and meet the early demolding requirements; then, it enters the stacking and natural curing stage, and continuous curing in the natural environment ensures that the concrete performance meets the standards; currently, in order to improve the utilization rate of curing sites and ensure the number of gate components stacked, the industry generally adopts the vertical stacking method to store gate components, in which the curved surface of the gate components is perpendicular to the ground.

[0003] However, there are specific posture requirements for the shipment and subsequent on-site construction of the tunnel lining components, which must be adjusted to a curved-face downward position. This position not only ensures transportation safety by distributing the weight of the components through the appropriate contact between the curved surface and the transport carrier, preventing structural displacement due to uneven stress during transportation, but also directly matches the "curved-face downward" installation benchmark during on-site tunnel construction, reducing secondary adjustment procedures and improving construction efficiency. Existing tunnel lining component flipping processes are difficult to meet the above requirements and have significant drawbacks: most methods use manual gantry crane operations, specifically involving lifting vertically stacked tunnel lining components with a gantry crane, laying rubber rods on the ground as temporary supports, lowering the components onto the rubber rods, and then operating the gantry crane to pull the components diagonally by moving forward and backward, forcing them to flip around the rubber rods. The process involves three main problems: First, the gantry crane must withstand non-axial loads during the inclined pulling process. Long-term use can easily lead to deformation of the gantry crane's lifting structure and accelerated wear of the wire rope, significantly shortening the gantry crane's service life and increasing equipment maintenance costs and safety hazards. Second, during the flipping process, the contact between the gantry crane and the rubber rod and the ground is an uncontrollable rigid collision. The sharp corners of the concrete surface are very prone to bumps and damage, requiring additional manpower for repairs. This not only increases labor costs but may also affect the structural integrity of the gantry crane due to uneven repair quality. Third, the entire flipping process relies on manual control of the gantry crane's operational precision, resulting in low flipping efficiency. Furthermore, human judgment errors can easily lead to deviations in the flipping posture of the gantry crane, failing to meet the requirements for consistent shipping posture and further affecting subsequent loading and construction progress.

[0004] In summary, the existing component flipping process has significant shortcomings in terms of equipment protection, product quality assurance, and operational efficiency. There is an urgent need to design a dedicated flipping device to solve the problem of smoothly and efficiently flipping components from a vertical stacking state to a curved-face-down shipping state. Utility Model Content

[0005] The present invention aims to provide a product turning machine for door components, in order to solve the problems in the prior art where manual assistance with the oblique pulling of the door crane easily damages the door crane, the concrete edges of the door components are easily damaged by collision, the turning efficiency is low, and the posture is difficult to guarantee.

[0006] The embodiments of this utility model are implemented as follows: This utility model embodiment provides a product flipping machine for parts, which includes a base, a flipping frame, a hydraulic system and an electrical control system; The aforementioned tilting frame is located on top of the aforementioned base, and the aforementioned tilting frame is rotatably connected to the aforementioned base via cylindrical roller bearings; The hydraulic system is located between the base and the tilting frame. One end of the hydraulic system is hinged to the base, and the other end of the hydraulic system is hinged to the tilting frame. The electrical control system is electrically connected to the hydraulic system. The base is equipped with a mechanical limit switch for triggering the tilting frame to rotate into position, and the mechanical limit switch is electrically connected to the electrical control system.

[0007] In use, first operate the hydraulic system to lift and support the tilting frame on the base. Then, use a gantry crane to transfer the vertically stacked parts to the tilting frame, ensuring that the parts fit snugly against the support structure on the tilting frame. Next, operate the hydraulic system to retract synchronously, causing the tilting frame to rotate slowly around the cylindrical roller bearing as the rotation center. During this process, the mechanical limit switch monitors the rotation angle of the tilting frame in real time. When the tilting frame rotates to 90° so that the curved surface of the parts faces down, the mechanical limit switch triggers a signal, the hydraulic system stops operating and locks, and the tilting of the parts is completed. Finally, use the gantry crane to lift the tilted parts off the tilting frame and transfer them to the shipping vehicle, thus completing one tilting operation.

[0008] The product turning machine for gantry cranes disclosed in this embodiment uses the aforementioned base and turning frame as the core force-bearing structure, and is equipped with the aforementioned cylindrical roller bearings to achieve stable rotation of the turning frame. With the help of the aforementioned hydraulic system, the turning frame is driven to complete a 90° synchronous turn around the aforementioned cylindrical roller bearings. The aforementioned mechanical limit switches provide safety protection and precise control for the turning process. It can effectively solve the problems of easy damage to the gantry crane, easy breakage of the concrete edges of the gantry crane, and low turning efficiency when manually assisting the turning of gantry cranes. As a result, the product turning machine for gantry cranes has the beneficial effects of realizing the turning of gantry cranes from a vertical stacking state to a curved surface facing down for shipment, realizing automatic turning, ensuring the quality of gantry crane shipment, improving operational safety, and increasing shipment efficiency.

[0009] Optionally: The base is provided with a first column, a second column, a first flip frame ear, a second flip frame ear, and a third flip frame ear; The aforementioned tilting frame has a receiving platform and a tilting platform. The middle part of the receiving platform is rotatably connected to the top of the first tilting frame lug, the second tilting frame lug, and the third tilting frame lug via the aforementioned cylindrical roller bearing. The end of the aforementioned receiving platform closest to the aforementioned first column and the aforementioned second column is supported on the top of the aforementioned first column and the aforementioned second column.

[0010] This configuration, through the cooperation of the first, second, and third tilting frame lugs with the cylindrical roller bearings, provides stable and flexible rotational support for the tilting frame, ensuring balanced force during tilting and preventing tilting or jamming. Furthermore, the collaborative support structure of the first and second columns with the first, second, and third tilting frame lugs forms multi-point stable support when the receiving platform receives the component, effectively dispersing the gravity load on the component, reducing local stress concentration on the base and tilting frame, minimizing the risk of structural deformation, and ensuring the stability of the component placement before tilting. This lays the foundation for subsequent precise 90° tilting, further improving the safety and reliability of the tilting operation and avoiding component breakage and equipment damage caused by traditional manual tilting.

[0011] Optionally: the first flip frame ear seat, the second flip frame ear seat and the third flip frame ear seat all have a first steel plate and a second steel plate that are parallel to each other and spaced apart. A first reinforcing rib plate is welded between the first steel plate and the second steel plate. The bottom ends of the first steel plate, the second steel plate and the first reinforcing rib plate are all vertically welded to the base. The first flip frame ear, the second flip frame ear, and the third flip frame ear are arranged at intervals along the axial direction of the flip frame.

[0012] This configuration significantly enhances the structural strength and deformation resistance of the first, second, and third tilting frame lugs, allowing them to stably withstand the loads of the tilting frame and the opening components, preventing breakage or deformation due to concentrated stress. Furthermore, the vertical welding method ensures the stability of the connection between the first, second, and third tilting frame lugs and the base. The axially spaced lugs provide uniform three-point support for the tilting frame, and together with the first and second steel plates, they provide a precise and stable support reference for the tilting frame's rotation. This effectively ensures the tilting frame rotates smoothly around the cylindrical roller bearing, further reducing the risk of collision damage to the opening components due to unstable support during tilting, while also reducing localized wear and improving the overall service life and operational safety of the tilting machine.

[0013] Optionally, the aforementioned tilting platform is provided with at least four support seats, each of which is rotatably connected to the tilting platform via a support seat pin, and a support seat spring is provided between the support seat and the tilting platform, the support seat spring being sleeved on the outside of the support seat pin.

[0014] With this configuration, the support base can rotate around the pin and adaptively adjust its angle under the elastic force of the support base spring. This allows it to closely fit the curved surface of the opening component, avoiding problems caused by differences in the opening component's specifications or errors in the precision of the curved surface. It effectively disperses the local pressure on the opening component, preventing damage to the curved surface and edges of the opening component due to excessive local stress. In addition, the arrangement of at least four support bases can form multi-point support. Combined with the buffering effect of the support base spring, it can absorb the slight vibration generated by the opening component during the flipping process, reducing the impact load on the opening component and the flipping table. At the same time, the support base spring structure can also compensate for the assembly gap between the support base and the opening component, further ensuring the stability of the opening component during the flipping process. This avoids product damage problems that are easily caused by traditional rigid supports, improving the safety of the flipping operation and the shipping quality of the opening component.

[0015] Optionally, the aforementioned support seat is elastically pressed against the arc surface of the opening part product by the aforementioned support seat spring.

[0016] With this configuration, the elastic force of the support spring allows the support to adapt to the shape of the curved surface of the component. Even if the component has a deviation in the precision of the curved surface or differences in specifications, it can ensure that the support and the curved surface are always in close contact, avoiding uneven stress caused by local suspension, effectively dispersing the load on the component, and preventing collision damage to its curved surface and edges due to local stress concentration. In addition, the elastic support structure can absorb the vibration and impact generated by the component during the flipping process, reducing the risk of damage caused by rigid contact. At the same time, it avoids the displacement of the component caused by unstable support in traditional manual flipping, further ensuring the stability of the flipping operation and the quality of the component shipment, and reducing subsequent repair costs.

[0017] Optionally, polyurethane panels are installed on the surfaces of both the aforementioned receiving platform and the aforementioned support base.

[0018] This design allows the polyurethane board to possess excellent elasticity and cushioning properties. When the receiving platform supports the connector and the support seat aligns with the curved surface of the connector, it prevents direct rigid contact between the connector and the metal receiving platform and support seat. This effectively absorbs vibrations and impacts generated during the flipping process, preventing damage to the concrete surface and edges of the connector due to collisions and friction, thus reducing subsequent repair work. Furthermore, the anti-slip properties of the polyurethane board enhance the friction between the connector and the receiving platform and support seat, preventing positional shifts that could affect flipping accuracy during the flipping process. This further ensures the stability of the connector during flipping and support. Simultaneously, the polyurethane board's wear and corrosion resistance reduces the wear rate of the receiving platform and support seat surfaces, extending the service life of key load-bearing components of the flipping machine and improving the overall operational reliability of the equipment.

[0019] Optionally, the hydraulic system includes two synchronously operating hydraulic cylinders, the tail end of the cylinder body of the hydraulic cylinder is hinged to the cylinder pin of the base, and the outer end of the telescopic rod of the hydraulic cylinder is hinged to the tilting frame.

[0020] This configuration allows the two hydraulic cylinders to operate synchronously, providing a balanced and stable driving force to the tilting frame. This ensures that the tilting frame smoothly completes a 90° tilt around the cylindrical roller bearing as its rotation center, preventing tilting jams or tilting of the opening due to uneven force on one side. This guarantees the safety and accuracy of the tilting process. In addition, the hinged connection between the cylinder body and the base, and between the telescopic rod and the tilting frame, can flexibly adapt to changes in the angle of the tilting frame during rotation. This avoids additional stress caused by rigid connections, reduces local wear on the hydraulic cylinders, the tilting frame, and the base, and extends the service life of the hydraulic system and the overall equipment. Furthermore, the synchronous drive design significantly improves work efficiency compared to traditional manual tilting, further reducing the risk of breakage of the opening due to unstable tilting.

[0021] Optionally: A tilting pin is provided at the axis of the cylindrical roller bearing between the first steel plate and the second steel plate, and the tilting pin passes through the first steel plate, the second steel plate and the cylindrical roller bearing; Both the first steel plate and the second steel plate are provided with a clamping plate on the side away from the cylindrical roller bearing. The clamping plate is provided with a slot on the flipping frame pin corresponding to the clamping plate. The clamping plate is engaged in the slot and bolted to the first steel plate or the second steel plate.

[0022] With this configuration, the aforementioned tilting frame pin can accurately position the aforementioned cylindrical roller bearing, preventing axial displacement of the cylindrical roller bearing during the rotation of the tilting frame. This ensures stable rotation of the tilting frame around the cylindrical roller bearing as the center, preventing jamming or tilting of the opening component due to bearing misalignment. Furthermore, the locking mechanism between the locking plate and the locking groove, along with the bolt fixing structure, further locks the position of the tilting frame pin, preventing it from loosening or falling off. This also enhances the connection stability between the first steel plate, the second steel plate, and the tilting frame pin, effectively bearing the load of the tilting frame and the opening component. It reduces localized wear between the tilting frame pin and the first and second steel plates, lowering the risk of equipment failure and further ensuring the safety and reliability of the tilting operation, preventing collision damage to the opening component due to loose equipment parts.

[0023] Optionally, a first bushing and a second bushing are respectively provided between the first steel plate and the second steel plate and the cylindrical roller bearing, and the first bushing and the second bushing are both sleeved on the tilting frame pin.

[0024] This configuration prevents the first and second bushings from directly contacting the cylindrical roller bearings, reducing wear on the bearings during rotation of the tilting frame. It also provides radial positioning for the bearings, preventing radial displacement and ensuring smooth rotation of the tilting frame around the bearings. This prevents tilting or collision damage to the components due to unstable tilting. Furthermore, the bushings fill the gaps between the steel plates and the bearings, reducing vibration and noise during tilting. They also provide a seal, minimizing dust and impurities from entering the bearings and extending their lifespan. This enhances the overall reliability and safety of the equipment, ensuring stable 90° tilting of the components.

[0025] Optionally: The electrical control system includes a control cabinet and a wireless remote controller, the control cabinet being electrically connected to the aforementioned hydraulic system, and the wireless remote controller being signal-connected to the control cabinet; The electrical control system is equipped with a PLC and relays. The PLC is electrically connected to the hydraulic system mentioned above through the relays.

[0026] With this setup, the PLC, combined with relays, can precisely control the hydraulic system's actions, especially ensuring the synchronous extension and retraction of the two hydraulic cylinders. This guarantees the tilting frame can smoothly complete a 90° tilt, preventing tilting or jamming of the components due to uncoordinated hydraulic system actions. Furthermore, the wireless remote controller enables remote operation, eliminating the need for operators to be close to the tilting work area, reducing safety hazards. The electrical connection between the control cabinet and the hydraulic system, combined with PLC program control, significantly improves work efficiency compared to traditional manual tilting, reduces human error, further ensures the stability of the components during tilting, prevents damage due to improper operation, and enhances equipment usability and operational safety.

[0027] Optionally: Both the base and the tilting frame are made of H-beams, and several second and third reinforcing ribs are welded between the two wings of the H-beam base and the tilting frame.

[0028] With this design, the H-beam itself possesses excellent bending and torsional resistance, serving as a core load-bearing structure to stably support the weight of the fittings and the load during the flipping process. Furthermore, welding several of the aforementioned second and third reinforcing ribs between the two wings further enhances the structural strength and rigidity of the H-beam, effectively dispersing localized stresses generated during the flipping operation. This prevents deformation and breakage of the base or flipping frame due to concentrated stress, while simultaneously improving the overall structural stability. This ensures the flipping frame smoothly completes a 90° flip centered on the cylindrical roller bearing, reducing the risk of fitting collision damage due to structural instability, extending equipment lifespan, and ensuring long-term reliable flipping operations.

[0029] Optionally, a fourth reinforcing rib is welded at the angle between the two ends of the aforementioned receiving platform and the aforementioned tilting platform.

[0030] With this design, the included angle, as a critical connection area between the receiving platform and the tilting platform, is prone to stress concentration during tilting operations due to the weight of the fitting and the tilting torque. The fourth reinforcing rib can effectively disperse the load in this area, enhance the structural strength and rigidity of the connection between the receiving platform and the tilting platform, and prevent weld cracking or structural deformation at the included angle. In addition, the fourth reinforcing rib can strengthen the overall coordination between the receiving platform and the tilting platform, ensuring that they maintain a stable structural shape during the tilting of the fitting, preventing the fitting from tilting off-center or vibrating more due to local structural weakness, further ensuring the stability of the tilting operation, reducing the risk of collision damage to the fitting due to structural shaking, extending the overall service life of the tilting frame, and improving the reliability of equipment operation.

[0031] Optionally, diagonal bracing is welded at the angle between the first and second columns and the base.

[0032] With this configuration, the diagonal braces can effectively disperse the stress at the connection points between the first and second columns and the base. Especially when the receiving platform supports the weight of the fitting, it can prevent weld cracking or structural deformation at the angle due to stress concentration, significantly enhancing the structural strength and stability of the connection between the first and second columns and the base. In addition, the diagonal braces can strengthen the anti-tipping ability of the first and second columns, preventing them from shifting laterally during the load-bearing or flipping operation of the tilting frame. This ensures the stable support of the first and second columns for the receiving platform, thereby guaranteeing the stability of the fitting during placement and the accuracy of subsequent flipping, reducing the risk of fitting collision damage due to column instability, and improving the overall reliability and service life of the tilting machine.

[0033] In summary, the opening component flipping machine disclosed in this utility model has the beneficial effects of realizing the transformation of opening components from a vertical stacking state to a curved-side-down shipping state, achieving automatic flipping, ensuring the shipping quality of opening components, improving operational safety, and increasing shipping efficiency.

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0038] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0039] Example See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5, Figure 6 and Figure 7 This embodiment proposes a product flipping machine for parts, including a base 1, a flipping frame 2, a hydraulic system 3 and an electrical control system (not shown in the figure); The tilting frame 2 is located on top of the base 1, and the tilting frame 2 is rotatably connected to the base 1 via a cylindrical roller bearing 4; The hydraulic system 3 is located between the base 1 and the tilting frame 2. One end of the hydraulic system 3 is hinged to the base 1, and the other end of the hydraulic system 3 is hinged to the tilting frame 2. The electrical control system is electrically connected to the hydraulic system 3. The base 1 is equipped with a mechanical limit switch 5 for triggering the rotation of the tilting frame 2 to the desired position. The mechanical limit switch 5 is electrically connected to the electrical control system.

[0040] In use, first operate the hydraulic system 3 to lift and support the tilting frame 2 on the base 1. Then, use a gantry crane to transfer the vertically stacked parts to the tilting frame 2, ensuring that the parts fit snugly against the support structure on the tilting frame 2. Next, operate the hydraulic system 3 to retract synchronously, causing the tilting frame 2 to rotate slowly around the cylindrical roller bearing 4 as the rotation center. During this process, the mechanical limit switch 5 monitors the rotation angle of the tilting frame 2 in real time. When the tilting frame 2 rotates to 90° so that the curved surface of the parts faces down, the mechanical limit switch 5 triggers a signal, the hydraulic system 3 stops and locks, and the tilting of the parts is completed. Finally, use the gantry crane to lift the tilted parts off the tilting frame 2 and transfer them to the shipping vehicle, thus completing one tilting operation.

[0041] This embodiment discloses a product turning machine for gantry cranes. It uses a base 1 and a turning frame 2 as the core load-bearing structure, and uses cylindrical roller bearings 4 to achieve stable rotation of the turning frame 2. A hydraulic system 3 drives the turning frame 2 to complete a 90° synchronous turn around the cylindrical roller bearings 4. Mechanical limit switches 5 provide safety protection and precise control during the turning process. This effectively solves the problems of easy damage to the gantry crane, easy breakage of the concrete edges of the gantry crane, and low turning efficiency when manually turning gantry cranes. Therefore, this product turning machine for gantry cranes has the beneficial effects of automatically turning gantry cranes from a vertical stacking state to a curved-side-down shipping state, ensuring the quality of gantry crane shipment, improving operational safety, and increasing shipping efficiency.

[0042] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The base 1 is provided with a first column 6, a second column 7, a first flip frame ear seat 8, a second flip frame ear seat 9 and a third flip frame ear seat 10; The tilting frame 2 has a receiving platform 11 and a tilting platform 12. The middle part of the receiving platform 11 is rotatably connected to the top of the first tilting frame ear 8, the second tilting frame ear 9 and the third tilting frame ear 10 through a cylindrical roller bearing 4. One end of the receiving platform 11, near the first column 6 and the second column 7, is supported on the top of the first column 6 and the second column 7. This, through the cooperation of the first tilting frame lug 8, the second tilting frame lug 9, and the third tilting frame lug 10 with the cylindrical roller bearing 4, provides stable and flexible rotational support for the tilting frame 2, ensuring balanced force during tilting and preventing tilting or jamming. Furthermore, the collaborative support structure of the first column 6 and the second column 7 with the first tilting frame lug 8, the second tilting frame lug 9, and the third tilting frame lug 10 forms multi-point stable support when the receiving platform 11 receives the component, effectively dispersing the gravity load of the component, reducing local stress concentration on the base 1 and the tilting frame 2, reducing the risk of structural deformation, and ensuring the stability of the component placement before tilting. This lays the foundation for subsequent precise 90° tilting, further improving the safety and reliability of the tilting operation and avoiding component breakage and equipment damage caused by traditional manual tilting.

[0043] The first tilting frame ear seat 8, the second tilting frame ear seat 9, and the third tilting frame ear seat 10 each have a first steel plate 13 and a second steel plate 14 that are parallel to each other and spaced apart. A first reinforcing rib plate 15 is welded between the first steel plate 13 and the second steel plate 14. The bottom ends of the first steel plate 13, the second steel plate 14, and the first reinforcing rib plate 15 are all vertically welded to the base 1. The first tilting frame ear seat 8, the second tilting frame ear seat 9, and the third tilting frame ear seat 10 are arranged at intervals along the axial direction of the tilting frame 2. The combined structure of the first steel plate 13, the second steel plate 14, and the first reinforcing rib plate 15 can significantly improve the structural strength and deformation resistance of the first tilting frame ear seat 8, the second tilting frame ear seat 9, and the third tilting frame ear seat 10, and can stably support the tilting frame 2 and the mouth. The load on the sub-components is reduced to prevent the lugs from breaking or deforming due to concentrated stress. In addition, the vertical welding method ensures the stability of the connection between the first tilting frame lug 8, the second tilting frame lug 9, and the third tilting frame lug 10 and the base 1. The first tilting frame lug 8, the second tilting frame lug 9, and the third tilting frame lug 10, which are spaced apart along the axis, can form a uniform three-point support for the tilting frame. Together with the structure of the first steel plate 13 and the second steel plate 14, they provide a precise and stable support reference for the rotation of the tilting frame 2, effectively ensuring that the tilting frame 2 rotates smoothly around the cylindrical roller bearing 4. This further reduces the risk of collision damage to the sub-components due to unstable support during the tilting process, while reducing local wear of the equipment and improving the overall service life and operational safety of the tilting machine.

[0044] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5, Figure 6 and Figure 7 The tilting table 12 is equipped with at least four support seats 16, which are made of 20mm thick steel plates. Each support seat 16 is rotatably connected to the tilting table 12 via a support seat pin 17. A support seat spring 18 is provided between the support seat 16 and the tilting table 12. The support seat spring 18 is sleeved on the outside of the support seat pin 17 to ensure that the support seat 16 fits the curved surface of the part. The support seat 16 can rotate around the pin and adaptively adjust its angle under the elastic force of the support seat spring 18, which can tightly fit the curved surface of the part and avoid the problem of loose fit caused by differences in part specifications or errors in the precision of the curved surface. This effectively disperses local pressure on the opening component, preventing damage to the curved surface and edges of the opening component due to excessive local stress. In addition, the setting of at least four support seats 16 can form multi-point support. With the buffering effect of the support seat spring 18, it can absorb the slight vibration generated by the opening component during the flipping process, reduce the impact load on the opening component and the flipping table 12. At the same time, the support seat spring 18 structure can also compensate for the assembly gap between the support seat 16 and the opening component, further ensuring the stability of the opening component during the flipping process, avoiding the product damage problems that are easily caused by traditional rigid supports, and improving the safety of the flipping operation and the shipping quality of the opening component.

[0045] The support seat 16 is elastically pressed against the curved surface of the part by the support seat spring 18. The elastic force of the support seat spring 18 enables the support seat 16 to adapt to the shape of the curved surface of the part. Even if there are deviations in the precision of the curved surface or differences in specifications, it can ensure that the support seat 16 is always in close contact with the curved surface, avoiding uneven force caused by local suspension, effectively dispersing the load of the part, and preventing its curved surface and edges from being damaged by collision due to local stress concentration. In addition, the elastic pressing structure can absorb the vibration and impact generated by the part during the flipping process, reducing the risk of damage caused by rigid contact. At the same time, it avoids the displacement of the part caused by unstable support in traditional manual flipping, further ensuring the stability of the flipping operation and the quality of the part shipment, and reducing subsequent repair costs.

[0046] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7Both the receiving platform 11 and the support seat 16 are covered with polyurethane panels (not shown in the figure). The polyurethane panels have good elasticity and cushioning properties, which can prevent direct rigid contact between the opening component and the metal receiving platform 11 and support seat 16 when the receiving platform 11 receives the opening component and the support seat 16 fits against the curved surface of the opening component. This effectively absorbs the vibration and impact generated by the opening component during the flipping process, preventing damage to the concrete surface and edges of the opening component due to collision and friction, and reducing the amount of subsequent repair work. In addition, the anti-slip properties of the polyurethane panels can enhance the friction between the opening component and the receiving platform 11 and support seat 16, preventing the opening component from affecting the flipping accuracy due to positional displacement during the flipping process, and further ensuring the stability of the opening component during the flipping and support process. At the same time, the polyurethane panels are wear-resistant and corrosion-resistant, which can reduce the wear rate of the surfaces of the receiving platform 11 and support seat 16, extend the service life of the key load-bearing components of the flipping machine, and improve the overall operational reliability of the equipment.

[0047] The hydraulic system 3 includes two synchronously operating hydraulic cylinders 19. The tail end of the cylinder body of the hydraulic cylinder 19 is hinged to the cylinder pin of the base 1, and the outer end of the telescopic rod of the hydraulic cylinder 19 is hinged to the tilting frame 2. The synchronous operation of the two hydraulic cylinders 19 can provide a balanced and stable driving force for the tilting frame 2, ensuring that the tilting frame 2 can smoothly complete a 90° tilt with the cylindrical roller bearing 4 as the rotation center. This avoids tilting jamming or tilting of the opening due to uneven force on one side, ensuring the safety and accuracy of the tilting process. In addition, the hinged connection between the cylinder body and the base 1, and between the telescopic rod and the tilting frame 2, can flexibly adapt to the angle changes when the tilting frame 2 rotates, avoiding the additional stress generated by rigid connection, reducing local wear of the hydraulic cylinder 19, the tilting frame 2, and the base 1, and extending the service life of the hydraulic system 3 and the overall equipment. At the same time, the synchronous drive design significantly improves the work efficiency compared with the traditional manual tilting, and further reduces the risk of damage to the opening due to unstable tilting.

[0048] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7A tilting pin 20 is provided at the axis of the cylindrical roller bearing 4 between the first steel plate 13 and the second steel plate 14. The tilting pin 20 passes through the first steel plate 13, the second steel plate 14, and the cylindrical roller bearing 4. A retaining plate 21 is provided on the side of the first steel plate 13 and the second steel plate 14 away from the cylindrical roller bearing 4. A retaining groove 22 is provided on the tilting pin 20 corresponding to the retaining plate 21. The retaining plate 21 is engaged in the retaining groove 22 and bolted to the first steel plate 13 or the second steel plate 14. The tilting pin 20 can accurately position the cylindrical roller bearing 4, preventing axial displacement of the cylindrical roller bearing 4 during the rotation of the tilting frame 2, and ensuring that the tilting frame 2 is in good position with the cylindrical roller bearing... 4. The rotating mechanism ensures stable rotation around the center, preventing the opening component from becoming stuck or tilted due to misalignment of the cylindrical roller bearing 4. In addition, the snap-fit ​​between the clamping plate 21 and the clamping groove 22, along with the bolt fixing structure, further locks the position of the tilting frame pin 20, preventing it from loosening or falling off. This also enhances the connection stability between the first steel plate 13, the second steel plate 14, and the tilting frame pin 20, effectively bearing the load of the tilting frame 2 and the opening component. This reduces localized wear between the tilting frame pin 20 and the first steel plate 13 and the second steel plate 14, lowers the risk of equipment failure, further ensures the safety and reliability of the tilting operation, and prevents the opening component from being damaged by collision due to loose equipment parts.

[0049] A first bushing 23 and a second bushing 24 are respectively provided between the first steel plate 13 and the second steel plate 14 and the cylindrical roller bearing 4. Both the first bushing 23 and the second bushing 24 are fitted onto the tilting frame pin 20. The first bushing 23 and the second bushing 24 prevent direct contact between the first steel plate 13 and the second steel plate 14 and the cylindrical roller bearing 4, reducing wear on the cylindrical roller bearing 4 during the rotation of the tilting frame 2. Simultaneously, they provide radial positioning for the cylindrical roller bearing 4, preventing radial displacement during stress and ensuring the stability of the tilting frame. 2. The cylindrical roller bearing 4 rotates smoothly around the center, preventing the opening part from tilting or being damaged by collision due to unstable rotation. In addition, the first bushing 23 and the second bushing 24 can fill the assembly gap between the first steel plate 13 and the second steel plate 14 and the cylindrical roller bearing 4, reducing the vibration and noise between the parts during the rotation process. They can also form a sealed protection for the cylindrical roller bearing 4, reducing the entry of external dust and impurities into the cylindrical roller bearing 4, extending the service life of the cylindrical roller bearing 4, further improving the overall reliability of the equipment and the safety of the rotation operation, and ensuring that the opening part can be stably rotated 90°.

[0050] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7The electrical control system includes a control cabinet (not shown in the figure) and a wireless remote controller (not shown in the figure). The control cabinet is electrically connected to the hydraulic system 3, and the wireless remote controller is signal connected to the control cabinet. The electrical control system is equipped with a PLC (not shown in the figure) and relays (not shown in the figure). The PLC is electrically connected to the hydraulic system 3 through the relays. The PLC, in combination with the relays, can precisely control the actions of the hydraulic system 3, especially ensuring the synchronous extension and retraction of the two hydraulic cylinders 19, ensuring that the tilting frame 2 can smoothly complete a 90° tilt, and avoiding tilting or jamming of the opening due to uncoordinated actions of the hydraulic system 3. In addition, the wireless remote controller can realize remote operation without the need for operators to come into close contact with the tilting operation area, reducing safety hazards. At the same time, the electrical connection design between the control cabinet and the hydraulic system 3, combined with the program control of the PLC, greatly improves the work efficiency compared with traditional manual tilting, reduces human operation error, further ensures the stability of the opening during the tilting process, avoids damage to the opening due to improper operation, and improves the convenience of equipment use and operational safety.

[0051] Both the base 1 and the tilting frame 2 are constructed of H-beams. Several second reinforcing ribs 25 and third reinforcing ribs 26 are welded between the two wings of the H-beams. The H-beams themselves have excellent bending and torsional resistance, and can serve as the core load-bearing structure to stably support the weight of the components and the load during the tilting process. In addition, the welding of several second reinforcing ribs 25 and several third reinforcing ribs 26 between the two wings can further enhance the structural strength and rigidity of the H-beams, effectively disperse the local stress generated during the tilting operation, and avoid deformation and breakage of the base 1 or the tilting frame 2 due to concentrated stress. At the same time, it improves the stability of the overall structure, ensuring that the tilting frame 2 can smoothly complete a 90° tilt around the cylindrical roller bearing 4, reducing the risk of collision damage to the components due to structural instability, extending the service life of the equipment, and ensuring long-term reliable tilting operations.

[0052] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7A fourth reinforcing rib plate 27 is welded at the included angle between the receiving platform 11 and the tilting platform 12. The included angle is a key connection area between the receiving platform 11 and the tilting platform 12. It is prone to stress concentration during the tilting operation due to the weight of the opening component and the tilting torque. The fourth reinforcing rib plate 27 can effectively distribute the load in this area, enhance the structural strength and rigidity of the connection between the receiving platform 11 and the tilting platform 12, and prevent weld cracking or structural deformation at the included angle. In addition, the fourth reinforcing rib plate 27 can enhance the overall coordination between the receiving platform 11 and the tilting platform 12, ensure that the two maintain a stable structural shape during the tilting of the opening component, prevent the opening component from tilting off-center or vibrating more due to local structural weakness, further ensure the stability of the tilting operation, reduce the risk of collision damage to the opening component due to structural shaking, extend the overall service life of the tilting frame 2, and improve the reliability of equipment operation.

[0053] A diagonal brace 28 is welded at the angle between the first column 6 and the second column 7 and the base 1. The diagonal brace 28 can effectively disperse the stress at the connection between the first column 6 and the second column 7 and the base 1. Especially when the receiving platform 11 supports the weight of the component, it can prevent weld cracking or structural deformation due to stress concentration at the angle, and significantly enhance the structural strength and stability of the connection between the first column 6 and the second column 7 and the base 1. In addition, the diagonal brace 28 can strengthen the anti-tipping ability of the first column 6 and the second column 7, prevent the first column 6 and the second column 7 from shifting laterally during the load-bearing or flipping operation of the flipping frame 2, ensure the stable support of the first column 6 and the second column 7 on the receiving platform 11, and thus ensure the stability of the component placement and the accuracy of subsequent flipping, reduce the risk of component collision damage due to column instability, and improve the overall reliability and service life of the flipping machine.

[0054] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7In this embodiment, the largest size of the component is currently 15 tons, with large dimensions in length, width, and height, making it difficult to flip. Manual flipping before shipment poses safety hazards, is labor-intensive and time-consuming, and can easily damage the edges of the component. This solution focuses on achieving automated flipping of large components. With the component stacked and its curved surface perpendicular to the ground, this solution designs a base 1, a flipping frame 2, a hydraulic system 3, and an electrical control system to create an automated flipping device. Operators press the button switch on the control cabinet or operate the wireless remote control to synchronize the extension and retraction of two hydraulic cylinders 19. The operation is controlled by a program to ensure the synchronization of the two hydraulic cylinders 19. By gradually retracting the hydraulic rods of the hydraulic cylinders 19, the flipping frame 2 rotates around the cylindrical roller bearing 4 until it is flipped to 90°, i.e., the curved surface of the component is facing down. At this point, the hydraulic cylinders 19 stop moving, thus achieving automated flipping of the component before shipment.

[0055] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 In this embodiment, the base 1 and the flipping frame 2 are load-bearing structural components, which are made of 250mm×250mm H-shaped steel. Several second reinforcing ribs 25 and several third reinforcing ribs 26 with a thickness of 12mm are welded on both sides of the H-shaped steel.

[0056] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 In this embodiment, when the longitudinal length of the opening component is 1990mm, six support seats 16 are attached; when the longitudinal length of the opening component is 1490mm, four support seats 16 are attached.

[0057] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7In this embodiment, the main structure of the turning machine is mainly constructed from 250mmH×250mmH steel welded together. The base 1 not only serves as a load-bearing support but its large frame structure also greatly improves overall stability. The turning frame 2 rotates the part to achieve a 90° turn. The hydraulic system 3 mainly serves as the power source during the turning process and is equipped with electrical components such as relays and PLCs. The hydraulic cylinder 19 is controlled by a program to start and stop. The mechanical limit switch 5 installed on the main structure provides safety protection for the entire turning operation. The control cabinet is installed next to the turning frame 2 and is equipped with a wireless remote controller, which enables wireless remote control operation during the turning process, improving the ease of use of the equipment.

[0058] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The specific operating principle of the component flipping machine in this embodiment is as follows: Before use, operate the hydraulic system 3 through the control cabinet of the electrical control system or the wireless remote controller to simultaneously lift the two hydraulic cylinders 19, pushing the tilting frame 2 to rotate upwards around the cylindrical roller bearing 4 installed on the base 1 (with a first bushing 23 and a second bushing 24 on the outside for sealing and dust prevention) as the rotation center, until the tilting frame 2 is supported on the first column 6, the second column 7, the first tilting frame ear seat 8, the second tilting frame ear seat 9, and the third tilting frame ear seat 10 of the base 1; then, transfer the vertically stacked (curved surface perpendicular to the ground) opening parts to the tilting frame 2 through the gantry crane, so that the curved surface of the opening parts fits against the support seats 16 on the tilting frame 2 (six support seats 16 for a longitudinal length of 1990mm, and four support seats 16 for a longitudinal length of 1490mm; the support seats 16 rotate through the support seat pin 17 and the support seat spring 18 elastically resists). The top is tightly fitted), and the structure of the tilting frame 2 is reinforced by the clamp plate 21 and the tilting frame pin 20. Then, the electrical control system is operated, and the hydraulic system 3 is controlled by the PLC and relay to make the two hydraulic cylinders 19 retract synchronously, driving the tilting frame 2 to rotate slowly around the cylindrical roller bearing 4. During the process, the mechanical limit switch 5 on the base 1 or the tilting frame 2 monitors the tilting angle in real time. When the tilting frame 2 rotates to 90° and the opening part reaches the shipping state with the arc surface facing down, the mechanical limit switch 5 triggers a signal, the hydraulic system 3 immediately stops and locks the hydraulic cylinder 19 to prevent the tilting frame 2 from shifting due to the failure of the hydraulic system 3. Finally, the tilted opening part is lifted off the tilting frame 2 by the gantry crane and transferred to the shipping vehicle, completing one opening part tilting operation. The whole process achieves safe and automatic tilting of the opening part from the stacking state to the shipping state with the help of the cooperation of various components.
