Description

Technical Field

[0001] This application relates to the technical field of prefabricated building component production methods, and in particular to a method for linking a heavy-duty vertical warehouse and production line for prefabricated buildings. Background Technology

[0002] Thin-shell components in prefabricated buildings are curved surface components made of rigid materials such as reinforced concrete, with a thickness only a fraction of their span. These thin-shell components are subjected to spatial stress, primarily bearing axial forces within the curved surface, while bending and torque are minimal. Therefore, the concrete strength is fully utilized, and the load-bearing and enclosure functions are integrated. In practical engineering, the cutting and combination of spatial curved surfaces can create uniquely shaped and novel buildings adaptable to various planar designs, offering advantages such as light weight, material savings, large span, and diverse shapes.

[0003] In the production process of thin-shell components, after the thin-shell component is cast into shape using a mold, it is transferred from the casting site to the mold table using a forklift. The mold table then circulates on the production line, where the thin-shell component undergoes precise dimensional and shape cutting, drilling, and assembly. However, using a forklift to transfer the thin-shell component from the casting site to the mold table has the following drawbacks: Because the processing speed of the thin-shell component is slow while it circulates on the production line, the component cannot be promptly moved to the mold table after casting at the casting site, thus occupying the casting area, wasting space resources, and resulting in low production efficiency. Furthermore, the limited space in the thin-shell component production workshop makes it inconvenient for forklifts to move within the workshop, and the poor visibility during the placement of the component on the mold table further complicates operations, reducing production efficiency. Summary of the Invention

[0004] The purpose of this application is to provide a method for linking a heavy-duty automated warehouse and a production line in prefabricated building construction, in order to solve the problem of low production line efficiency caused by the use of forklifts to transfer thin-shell components in the production process of thin-shell components in related technologies.

[0005] The technical solution provided in this application for a method of linking a prefabricated building heavy-duty vertical warehouse with a production line is as follows: A method for linking a prefabricated building heavy-duty automated warehouse with a production line includes the following steps: Step 1: Set up an automated warehouse in the production workshop. After the thin-shell components are cast, they are transferred from the casting site to the production workshop by forklifts and stored in the automated warehouse by stacker cranes. Step 2: Set up a conveyor in the production workshop, use the conveyor to transport the pallets, use the stacker crane to transfer the thin-shell components in the automated warehouse onto the pallets, and use the conveyor to transport the pallets and thin-shell components to the area below the hoisting device. Step 3: Lift the pallet using a hoisting device and place the pallet and thin-shell components on the mold table. Move the mold table along the production line to process the thin-shell components.

[0006] By adopting the above technical solution, the thin-shell components after casting are stored in an automated warehouse, thus avoiding the situation where the thin-shell components cannot be moved to the mold table in a timely manner after casting is completed at the casting site, avoiding the occupation of the casting site and effectively improving production efficiency. Simultaneously, using pallets to support the thin-shell components and a conveyor system to transport the pallets and components avoids the inconvenience of forklift movement within the production workshop due to its limited space. Using a hoisting device to lift the pallets and place the pallets and components on the mold table avoids the inconvenience caused by poor visibility during forklift placement, further improving production efficiency.

[0007] Optionally, the hoisting device includes a frame, a translation mechanism, a lifting mechanism, and a lifting device. The translation mechanism is mounted on the frame, the lifting mechanism is connected to the translation mechanism, and the lifting device is connected to the lifting mechanism. In step 3, the method for hoisting the pallet using a hoisting device and placing the pallet and thin-shell components on the mold platform is as follows: the hoisting device is lowered by a lifting mechanism and connected to the pallet; the pallet is then lifted by the lifting mechanism; the lifting mechanism is moved horizontally by a translation mechanism to move the pallet above the mold platform; the pallet is then lowered and placed on the mold platform by the lifting mechanism, and the hoisting device is separated from the pallet.

[0008] By adopting the above technical solution, pallets and thin-shell components can be hoisted and transferred using translation mechanism, lifting mechanism and lifting device. This not only makes the operation more convenient and faster, improving production efficiency, but also improves the position control accuracy during transfer, making it easier to place the thin-shell components on the predetermined position of the mold table.

[0009] Optionally, the lifting device includes a hanger, a rotating shaft, and a rotary drive mechanism. The lifting mechanism is connected to the hanger. The tray is provided with a column, the column has a cavity and a through groove communicating with the cavity, the rotating shaft is rotatably mounted on the hanger, the rotating shaft is provided with a hook, the width of the through groove is adapted to the width of the hook, and the rotary drive mechanism is mounted on the hanger and connected to the rotating shaft. In step 3, the method for lifting the pallet using the lifting device is as follows: the lifting mechanism lowers the lifting frame so that the hook passes through the through slot and inserts into the cavity of the column. Then, the rotating drive mechanism drives the rotating shaft to rotate so that the hook rotates 90 degrees to hook the column. Then, the lifting mechanism drives the lifting frame to rise and lift the pallet using the hook.

[0010] By adopting the above technical solution, when it is necessary to lift the pallet, simply insert the hook through the through slot into the cavity of the column, and then drive the rotating shaft to rotate by the rotary drive mechanism, so that the hook can be rotated 90 degrees to hook the column. The operation is very convenient and quick, which can improve production efficiency.

[0011] Optionally, the rotary drive mechanism includes a slider, a first elastic element, and a first locking component. The slider is slidably mounted on the hanger. The first elastic element is mounted on the hanger and acts on the slider. The slider is connected to the rotating shaft. When the slider slides relative to the hanger, the slider can drive the rotating shaft to rotate. The first locking component is mounted on the hanger and is used to restrict the sliding of the slider relative to the hanger. In step 3, the lifting mechanism lowers the hanger, allowing the hook to pass through the slot and insert into the cavity of the column. Then, the sliding member abuts against the upper surface of the column and slides relative to the hanger. The sliding member drives the rotating shaft to rotate, causing the hook to rotate 90 degrees. Next, the first locking component locks the sliding member to prevent the hook from rotating. After the pallet and thin-shell component are placed on the mold table by the lifting device, the first locking component is separated from the sliding member. The lifting mechanism drives the hanger to rise, while the first elastic member drives the sliding member to slide, causing the hook to rotate until it aligns with the slot, and the hook is then removed from the cavity.

[0012] By adopting the above technical solution, when lifting a pallet, if it is necessary to control the rotation of the hook, it is only necessary to lower the lifting frame through the lifting mechanism, so that the hook passes through the through slot and is inserted into the cavity of the column. Then, the sliding part abuts against the upper end face of the column and slides relative to the lifting frame. The sliding part drives the rotating shaft and the hook to rotate. Therefore, it is only necessary to control the lifting of the lifting frame to control the rotation of the hook, which makes it easier for the staff to control and reduces the labor intensity of the operators.

[0013] Optionally, the rotary drive mechanism further includes a worm gear, the sliding member includes a first rack, the worm gear is rotatably mounted on the hanger, the first rack is slidably mounted on the hanger, the worm gear is provided with a first gear, the first gear meshes with the first rack, the rotating shaft is provided with a worm wheel, the worm gear meshes with the worm wheel, the first elastic member acts on the first rack, and the first locking component can act on the first rack; In step 3, when the sliding member slides relative to the hanger, it drives the first rack to slide relative to the hanger. The first rack drives the first gear and worm to rotate, and the worm drives the worm wheel and the rotating shaft to rotate, causing the hook to rotate 90 degrees.

[0014] By adopting the above technical solution, when the first rack slides relative to the hanger, the first rack can drive the first gear and worm to rotate, and then the worm can drive the worm wheel and the rotating shaft to rotate, thereby driving the hook to rotate 90 degrees and realize the hooking of the column.

[0015] Optionally, the lifting device further includes a first unlocking component. The first locking component includes a first locking block and a third elastic element. The first locking block is slidably disposed on the lifting frame. The third elastic element is disposed on the lifting frame and acts on the first locking block. The first rack is provided with a first locking groove that can engage with the first locking block. The first unlocking component is disposed on the lifting frame and connected to the first locking block. In step 3, when the first rack slides relative to the hanger and the hook rotates 90 degrees, the third elastic element drives the first locking block to engage with the first locking groove of the first rack, fixing the first rack relative to the hanger and preventing the hook from rotating. After the pallet and thin-shell component are placed on the mold table by the lifting device, the first unlocking component drives the first locking block to separate from the first locking groove, unlocking the first rack and allowing it to slide relative to the hanger.

[0016] By adopting the above technical solution, when it is necessary to separate the hook from the tray, the first unlocking component drives the first locking block to separate from the first locking groove, unlocking the first rack so that the first rack can slide relative to the hanger. When the lifting mechanism drives the hanger to rise, the first elastic element can drive the first rack to slide, thereby driving the hook to rotate to align with the through groove, so that the hook can be withdrawn from the cavity, thereby separating the hook from the upright of the tray.

[0017] Optionally, the lifting device further includes a retaining member. The first unlocking assembly includes a first sliding column, a second gear, a second rack, and a fifth elastic member. The first sliding column and the second rack are slidably disposed on the lifting frame. The fifth elastic member is disposed on the lifting frame and acts on the first sliding column. The first sliding column can abut against the upper end face of the column. The second rack is fixedly connected to the first locking block. The first sliding column is provided with a first toothed row. The second gear is rotatably disposed on the lifting frame and meshes with the first toothed row and the second rack. The retaining member is disposed on the lifting frame and acts on the first sliding column. In step 3, after the pallet and thin-shell component are placed on the mold table by the hoisting device, the hanger is moved down by the hoisting device so that the first sliding column abuts against the upper end face of the column and slides relative to the hanger. The second rack is driven to slide by the first gear and the second gear, which drives the first locking block to exit from the first locking groove. Then, the retaining member acts on the first sliding column to restrict the sliding of the first sliding column relative to the hanger.

[0018] By adopting the above technical solution, when the first locking block is driven to separate from the first locking groove by the first unlocking component and the first rack is unlocked, the retaining member acts on the first sliding post to restrict the sliding of the first sliding post relative to the hanger, thereby preventing the first sliding post from resetting under the action of the fifth elastic member, which would cause the first locking block to re-engage and lock with the first locking groove.

[0019] Optionally, the sliding member further includes a telescopic rod and a second elastic member. The telescopic rod is slidably disposed on the first rack, and the second elastic member is disposed on the first rack and acts on the telescopic rod. The telescopic rod can abut against the upper end face of the column, and the elastic coefficient of the second elastic member is greater than that of the first elastic member. In step 3, after the pallet and thin-shell component are placed on the mold table by the hoisting device, the hanger is moved down by the hoisting device so that the first sliding column abuts against the upper end face of the column and slides relative to the hanger. At the same time, the telescopic rod abuts against the upper end face of the column and slides relative to the first rack against the elastic force of the second elastic element.

[0020] By adopting the above technical solution, since the elastic coefficient of the second elastic element is greater than that of the first elastic element, the second elastic element only begins to compress after the first elastic element has been compressed to its maximum stroke. Therefore, when the telescopic rod slides relative to the first rack against the elastic force of the second elastic element, the first rack can be prevented from sliding, ensuring that the hook will not rotate.

[0021] Optionally, the retaining member includes a second locking block and a fourth elastic member. The second locking block is slidably disposed on the hanger, and the fourth elastic member is disposed on the hanger and acts on the second locking block. The first sliding column is provided with a second locking groove that can engage with the second locking block. In step 3, the first sliding column slides relative to the hanger and drives the second rack to slide through the first gear and the second gear, so that after the first locking block exits from the first locking groove, the fourth elastic element drives the second locking block to engage with the second locking groove of the first sliding column, thereby restricting the sliding of the first sliding column relative to the hanger.

[0022] By adopting the above technical solution, when the first sliding column slides relative to the hanger and drives the second rack to slide through the first gear and the second gear, causing the first locking block to exit from the first locking groove, the fourth elastic element drives the second locking block to engage with the second locking groove of the first sliding column, so that the first sliding column remains fixed relative to the hanger, thereby keeping the second rack and the first locking block fixed, and thus keeping the first unlocking component in the unlocked state.

[0023] Optionally, the lifting device further includes a reset assembly, which includes a second sliding column, a third gear and a third rack. The second sliding column is fixedly connected to the first rack, and a second toothed row is provided on the second sliding column. The third rack is slidably disposed on the lifting frame and fixedly connected to the second locking block. The third gear is rotatably disposed on the lifting frame and meshes with the second toothed row and the third rack. In step 3, after the retainer acts on the first sliding column, the lifting device drives the hanger to move upward. During the upward movement of the hanger, the first elastic element pushes the first rack and the second sliding column to slide relative to the hanger. The second gear and the third gear drive the third rack to slide relative to the hanger. The third rack drives the second locking block to separate from the second locking groove. Then, the fifth elastic element drives the first sliding column to reset.

[0024] By adopting the above technical solution, when the hook separates from the column, as the hanger continues to move upward, the telescopic rod separates from the column. The first elastic element pushes the first rack and the second sliding column to slide relative to the hanger. The second gear and the third gear drive the third rack to slide relative to the hanger. The third rack drives the second locking block to separate from the second locking groove. Then, the fifth elastic element drives the first sliding column to reset, causing the first gear to separate from the second gear, releasing the limit on the first locking block, thereby enabling the first locking component to work normally.

[0025] In summary, this application includes at least one of the following beneficial technical effects: By storing the cast thin-shell components in an automated warehouse, the inability to promptly move them to the mold table after casting at the casting site is avoided, thus preventing the occupation of the casting area and effectively improving production efficiency. Simultaneously, by using pallets to support the thin-shell components and a conveyor system to transport the pallets and components, the inconvenience of forklift movement within the production workshop due to its limited space is avoided. Furthermore, by using a hoisting device to lift the pallets and place the pallets and components on the mold table, the inconvenience caused by poor visibility during forklift placement is avoided, further improving production efficiency.

[0028] The following is in conjunction with the appendix Figure 1 -Appendix Figure 9 This application will be described in further detail below.

[0029] This application discloses a method for linking a prefabricated building heavy-duty vertical warehouse with a production line.

[0030] A method for linking a prefabricated building heavy-duty automated warehouse with a production line includes the following steps: Step 1, refer to Figure 1 and Figure 2 An automated warehouse 10 is set up in the production workshop. After the thin-shell components are cast, they are transferred from the casting site to the production workshop by forklifts and stored in the automated warehouse 10 by stacker cranes. Step 2: Install a conveying device 20 in the production workshop. The conveying device 20 can be a roller conveyor. The pallet 30 is conveyed through the conveying device 20. The thin-shell components in the automated warehouse 10 are transferred to the pallet 30 by the stacker crane. The pallet 30 and the thin-shell components are then conveyed to the area below the hoisting device through the conveying device 20. Step 3: Lift the pallet 30 using a hoisting device and place the pallet 30 and the thin-shell component on the mold table 40. The mold table 40 can be a movable mold table, which is moved on the production line to process the thin-shell component.

[0031] The automated warehouse 10 stores the cast thin-shell components, preventing them from being moved to the mold table immediately after casting, thus avoiding space occupation and improving production efficiency. Simultaneously, pallets 30 support the thin-shell components, and a conveyor 20 transports both the pallets and components, avoiding the inconvenience of forklift movement within the narrow production workshop. A hoisting device lifts the pallets 30 and places them on the mold table 40, preventing poor visibility and operational difficulties when placing the components on the mold table, further improving production efficiency.

[0032] In an optional embodiment, the production workshop can be multi-story, and a lifting device 90 can be installed within the workshop to lift the stacker crane, enabling cross-floor transport. The lifting device 90 can be an elevator, and the conveying device 20 can extend to the elevator entrance and exit. After the stacker crane is lifted by the lifting device 90, the stacker crane can directly transfer the thin-shell components onto the pallet 30 located on the conveying device 20. Multiple sets of conveying devices 20 can be provided to improve transport efficiency.

[0033] The tray 30 is provided with a column 31 and a stop 34. The column 31 is provided with a screw hole, and a screw rod 32 is threadedly connected to the column 31 through the screw hole. The end of the screw rod 32 is connected to a fixing plate 33. The thin-shell component placed on the tray 30 can be limited and fixed by the fixing plate 33 and the stop 34.

[0034] Reference Figure 2 , Figure 3 and Figure 4 In one optional embodiment, the structure of the hoisting device is as follows: The hoisting device includes a frame 50, a translation mechanism 60, a lifting mechanism 70, and a lifting device 80. The translation mechanism 60 is mounted on the frame 50 and can be a translation trolley. A guide rail can be installed on the frame 50 to allow the translation trolley to move on the guide rail. The lifting mechanism 70 is connected to the translation mechanism 60 and can be a wire rope winch. The translation mechanism 60 can drive the lifting mechanism 70 to translate. The lifting device 80 is connected to the lifting mechanism 70 and the lifting mechanism 70 can drive the lifting device 80 to lift. In step 3, the method for hoisting the pallet 30 using a hoisting device and placing the pallet 30 and the thin-shell component on the mold table 40 is as follows: the lifting device 80 is lowered by the lifting mechanism 70 and connected to the pallet 30; the pallet 30 is then lifted by the lifting mechanism 70; the lifting mechanism 70 is moved horizontally by the translation mechanism 60 to move the pallet 30 above the mold table 40; the pallet 30 is then lowered and placed on the mold table 40 by the lifting mechanism 70, and the lifting device 80 is separated from the pallet 30.

[0035] Reference Figure 4 , Figure 5 and Figure 6 In one optional embodiment, the specific structure of the lifting device 80 is as follows: The lifting device 80 includes a hanger 81, a rotating shaft 82, and a rotary drive mechanism 83. The lifting mechanism 70 is connected to the hanger 81. The column 31 is provided with a cavity 311 and a through groove 312 that communicates with the cavity 311. The rotating shaft 82 is rotatably mounted on the hanger 81. The rotating shaft 82 is provided with a hook 821. The width of the through groove 312 is adapted to the width of the hook 821. The rotary drive mechanism 83 is mounted on the hanger 81 and connected to the rotating shaft 82. More specifically, the rotary drive mechanism 83 includes a sliding member, a first elastic member, and a first locking component. The sliding member is slidably mounted on the hanger 81. The first elastic member is mounted on the hanger 81 and acts on the sliding member. The sliding member is connected to the rotating shaft 82. When the sliding member slides relative to the hanger 81, the sliding member can drive the rotating shaft 82 to rotate. The first locking component is mounted on the hanger 81 and is used to restrict the sliding member from sliding relative to the hanger 81.

[0036] In step 3, the method for hoisting the pallet 30 by means of the hoisting device is as follows: the lifting mechanism 70 lowers the lifting frame 81 so that the hook 821 passes through the through groove 312 and is inserted into the cavity 311 of the column 31; Next, the rotating shaft 82 is driven to rotate by the rotary drive mechanism 83, so that the hook 821 rotates 90 degrees to hook the column 31. More specifically, after the hook 821 passes through the through groove 312 and is inserted into the cavity 311 of the column 31, the sliding member abuts against the upper end face of the column 31 and slides relative to the hanger 81. The rotating shaft 82 is driven to rotate by the sliding member, so that the hook 821 rotates 90 degrees. Next, the slider is locked by the first locking component to prevent the hook 821 from rotating; then the lifting mechanism 70 drives the hanger 81 to rise, and the tray 30 is lifted by the hook 821.

[0037] Reference Figure 6 , Figure 7 and Figure 8 In an optional embodiment, the specific structure of the rotary drive mechanism 83 is as follows: The rotary drive mechanism 83 also includes a worm gear 831, and the sliding element includes a first rack 832, a telescopic rod 835, and a second elastic element. The worm gear 831 is rotatably mounted on the hanger 81, the first rack 832 is slidably mounted on the hanger 81, the worm gear 831 is provided with a first gear 8311, the first gear 8311 meshes with the first rack 832, and the rotating shaft 82 is provided with a worm wheel 822, the worm gear 831 meshes with the worm wheel 822. The first elastic element acts on the first rack 832. The first elastic element can be a first spring 837. More specifically, the first spring 837 is sleeved on the outside of the first rack 832. The hanger 81 is provided with a limiting surface 813. The first rack 832 is provided with a fourth limiting plate 8323. The fourth limiting plate 8323 can abut against the limiting surface 813. The two ends of the first spring 837 abut against the fourth limiting plate 8323 and the hanger 81 respectively. The telescopic rod 835 is slidably mounted on the first rack 832. The second elastic element is mounted on the first rack 832 and acts on the telescopic rod 835. The second elastic element can be a second spring 836. More specifically, the telescopic rod 835 is provided with a first limiting plate 8351, and the first rack 832 is provided with a second limiting plate 8322. The telescopic rod 835 slides through the first rack 832, and the second spring 836 is sleeved on the outside of the telescopic rod 835. The two ends of the second spring 836 abut against the first limiting plate 8351 and the second limiting plate 8322, respectively. The telescopic rod 835 can abut against the upper end face of the column 31. The elastic coefficient of the second elastic element is greater than that of the first elastic element. The first locking component can act on the first rack 832. More specifically, the first locking component includes a first locking block 833 and a third elastic element. The hanger 81 is provided with a first guide groove 811, and the first locking block 833 is slidably disposed in the first guide groove 811. The third elastic element is disposed on the hanger 81 and acts on the first locking block 833. The third elastic element can be a third spring 834. More specifically, the first locking block 833 is provided with a first sliding rod 8331, and the third spring 834 is sleeved on the outside of the first sliding rod 8331. The two ends of the third spring 834 respectively abut against the inner end faces of the first locking block 833 and the first guide groove 811. The first rack 832 is provided with a first locking groove 8321 that can engage with the first locking block 833.

[0038] In step 3, during the hoisting of the pallet 30 by the hoisting device, when the lifting mechanism 70 lowers the hanger 81 so that the hook 821 passes through the through slot 312 and inserts into the cavity 311 of the column 31, the lifting mechanism 70 continues to drive the hanger 81 to descend, so that the telescopic rod 835 abuts against the upper end face of the column 31 and drives the first rack 832 to slide relative to the hanger 81. At this time, the first spring 837 is compressed, and the second spring 836 does not deform. The first rack 832 drives the first gear 8311 and the worm 831 to rotate, and the worm 831 drives the worm wheel 822 and the rotating shaft 82 to rotate, so that the hook 821 rotates 90 degrees and can hook the column 31. When the hook 821 rotates 90 degrees, the first locking block 833 is driven by the third elastic element to engage with the first locking groove 8321 of the first rack 832, so that the first rack 832 is fixed relative to the hanger 81 to prevent the hook 821 from rotating. Then, the hanger 81 is driven to rise by the lifting mechanism 70, so that the column 31 and the tray 30 can be hooked and lifted by the hook 821.

[0039] Next, the pallet 30 and the thin-shell component are placed on the mold table 40 by the hoisting device. Then, the first locking component is separated from the sliding component, and the lifting frame 81 is driven to rise by the lifting mechanism 70. At the same time, the sliding component is driven to slide by the first elastic component, so that the hook 821 rotates to align with the through groove 312. The hook 821 is then removed from the cavity 311, so that the lifting device 80 is separated from the pallet 30.

[0040] Reference Figure 8 and Figure 9 In an optional embodiment, the first unlocking component 84 is disposed on the hanger 81 and connected to the first locking block 833. The first locking component can be separated from the sliding member through the first unlocking component 84 and the retaining member 85. The specific structure of the first unlocking component 84 and the retaining member 85 is as follows: The first unlocking component 84 includes a first sliding column 841, a second gear 842, a second rack 843, and a fifth elastic element. The first sliding column 841 and the second rack 843 are slidably mounted on the hanger 81. The fifth elastic element is mounted on the hanger 81 and acts on the first sliding column 841. The fifth elastic element may be a fifth spring 838. More specifically, the hanger 81 is provided with a limiting groove 812, the first sliding column 841 is provided with a third limiting plate 8411, and the fifth spring 838 is sleeved on the outside of the first sliding column 841. The two ends of the fifth spring 838 abut against the end faces of the third limiting plate 8411 and the limiting groove 812, respectively. The first sliding column 841 can abut against the upper end face of the column 31. The second rack 843 is fixedly connected to the first sliding rod 8331 on the first locking block 833. The first sliding column 841 is provided with a first gear row 8413. The second gear 842 is rotatably mounted on the hanger 81 and meshes with the first gear row 8413 and the second rack 843. The second rack 843 is provided with a second clearance groove 8431 for avoiding the first sliding column 841. The retainer 85 is provided on the hanger 81 and can act on the first sliding post 841. More specifically, the retainer 85 includes a second locking block 851 and a fourth elastic member. The hanger 81 is provided with a second guide groove 814. The second locking block 851 is slidably disposed in the second guide groove 814. The first sliding post 841 is provided with a second locking groove 8412 that can engage with the second locking block 851. The fourth elastic member is provided on the hanger 81 and acts on the second locking block 851. The fourth elastic element can be a fourth spring 852. More specifically, the second locking block 851 is provided with a second slide rod 8511, and the fourth spring 852 is sleeved on the outside of the second slide rod 8511. The two ends of the fourth spring 852 abut against the inner end faces of the second locking block 851 and the second guide groove 814, respectively. The first rack 832 is provided with a first clearance groove 8324 for avoiding the second slide rod 8511.

[0041] In step 3, after the pallet 30 and the thin-shell component are placed on the mold table 40 by the hoisting device, the first locking block 833 is driven to separate from the first locking groove 8321 by the first unlocking component 84, thereby unlocking the first rack 832 and allowing the first rack 832 to slide relative to the hanger 81. More specifically, after the pallet 30 and the thin-shell component are placed on the mold table 40 by the hoisting device, the hanger 81 is moved further down by the hoisting device, causing the telescopic rod 835 to abut against the upper end face of the column 31 and slide relative to the first rack 832 against the elastic force of the second elastic element. At the same time, the first sliding column 841 abuts against the upper end face of the column 31 and slides upward relative to the hanger 81. When the first sliding column 841 slides upward, the first gear row 8413 meshes with the second gear 842, and the first gear row 8413 and the second gear 842 drive the second rack 843 to slide, thereby causing the first locking block 833 to exit from the first locking groove 8321.

[0042] Next, the retaining member 85 acts on the first sliding column 841 to restrict the sliding of the first sliding column 841 relative to the hanger 81. More specifically, the fourth elastic member drives the second locking block 851 to engage with the second locking groove 8412 of the first sliding column 841, restricting the sliding of the first sliding column 841 relative to the hanger 81. Then, the lifting mechanism 70 drives the hanger 81 to rise. During the rising process, the second elastic member first springs back to its original position, and then the first elastic member springs back to its original position, pushing the first rack 832 to move downward relative to the hanger 81. The first rack 832 drives the hook 821 to rotate until it aligns with the through groove 312. Then, the lifting mechanism 70 continues to drive the hanger 81 to rise, disengaging the hook 821 from the cavity 311 and separating the lifting device 80 from the tray 30.

[0043] During the process of lifting the gantry 81 via the lifting mechanism 70, the second locking block 851 can be separated from the second locking groove 8412 by the reset assembly 86, and then the first sliding column 841 can be reset by the fifth elastic element. (Refer to...) Figure 8 and Figure 9 In an optional embodiment, the specific structure of the reset component 86 and the specific principle of driving the second locking block 851 to separate from the second locking groove 8412 are as follows: The reset assembly 86 includes a second sliding column 861, a third gear 862, and a third rack 863. The second sliding column 861 is fixedly connected to the fourth limiting plate 8323 on the first rack 832. The second sliding column 861 is provided with a second gear row 8611. The third rack 863 is slidably mounted on the hanger 81 and is fixedly connected to the second sliding rod 8511 on the second locking block 851. The third gear 862 is rotatably mounted on the hanger 81 and meshes with the second gear row 8611 and the third rack 863. The third rack 863 is provided with a third clearance groove 8631 for avoiding the second sliding column 861. In step 3, after the retainer 85 acts on the first sliding column 841, the lifting device drives the hanger 81 to move upward. During the upward movement of the hanger 81, the first elastic member pushes the first rack 832 and the second sliding column 861 to slide relative to the hanger 81. The second gear row 8611 and the third gear 862 drive the third rack 863 to slide relative to the hanger 81. The third rack 863 drives the second locking block 851 to separate from the second locking groove 8412. Then, the fifth elastic member drives the first sliding column 841 to reset.
