Description

Technical Field

[0001] The present invention relates to the technical field of flipping components, and specifically to a flipping device for precast components with an adaptive function. Background Art

[0002] The flipping of precast components is an important task in construction. By using a flipping device to flip the precast components, better installation or use during operation can be achieved. Therefore, a reasonable flipping device can improve construction efficiency, ensure construction safety and quality.

[0003] When flipping relatively large precast components, a flipping device that can be flipped 180° bilaterally is usually used. This device usually requires manual placement of the component on one side of the flipping plate. When one side of the flipping plate is flipped 90°, the other side carrying the component also flips 90° to carry the component to the other side, thus completing the flipping. This flipping device does not have specific fixation on both sides of the component, and problems such as deviation may occur during the flipping process. Moreover, when flipping asymmetric components, it may cause the center of gravity of the component to be unstable, resulting in unstable flipping. Currently, during the flipping process, two flipping mechanisms are used, which occupies a large space. Summary of the Invention

[0004] The purpose of the present invention is to provide a flipping device for precast components with an adaptive function to solve the problems raised in the prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions: A flipping device for precast components with an adaptive function, the flipping device includes a base, a support mechanism, a flipping assembly, a flipping mechanism, a lifting mechanism, a baffle mechanism, a conveying mechanism, and a center-of-gravity sensing device. The base and the support mechanism are firmly connected. There are two groups of support mechanisms, and the two groups of support mechanisms are respectively located on both sides of the base. The lower end of the base is hinged to the flipping assembly, the base is threadedly connected to the conveying mechanism, the support mechanism is rotationally connected to the flipping mechanism, the flipping mechanism is threadedly connected to the baffle mechanism, the upper end of the flipping mechanism is hinged to the flipping assembly, the flipping mechanism is slidably connected to the lifting mechanism, and the baffle mechanism is rotationally connected to the center-of-gravity sensing device.

[0006] There are two groups of supporting mechanisms on both sides of the base, and the two groups of supporting mechanisms support the flipping mechanism at the same time. The flipping assembly is connected to the base in rotation, and the flipping assembly is connected to the flipping mechanism in rotation. The flipping assembly flips the flipping mechanism 180° by rotating forward and backward. The prefabricated component is placed on the flipping mechanism, so the prefabricated component will flip along with the flipping mechanism. When the prefabricated component is placed on the flipping mechanism, since the bottom of the prefabricated component is not necessarily flat, the lifting mechanism rises to resist the bottom of one side of the prefabricated component to achieve balance. Before flipping, the baffle mechanism first slides to the middle end of the flipping mechanism, and then flips the flipping mechanism at a certain angle, so that the side of the prefabricated component is pressed on the center of gravity sensing device, and the baffle mechanism is translated to the position where the center of gravity of the prefabricated component is balanced through the center of gravity sensing device, and then a complete 180° flip is performed. After flipping, the flipping mechanism descends and approaches the conveying mechanism. After the conveying mechanism catches the prefabricated component and is stable, the baffle mechanism is translated to the side of the flipping mechanism, and the conveying mechanism can slide on the base, and the conveying mechanism drives the flipped prefabricated component to slide out of the front end of the base, and the flipped prefabricated component can be transferred away.

[0007] Furthermore, the base includes a bottom plate, a conveying slide rail, a first lead screw, a first motor and a first connecting frame. The bottom plate is tightly connected to the supporting mechanism. Two groups of bottom plates are arranged. The two groups of bottom plates are respectively located on both sides of the conveying mechanism. A conveying slide rail is arranged on the bottom plate. A first connecting frame is arranged on the bottom plate. The two first connecting frames are respectively placed on both sides of the supporting mechanism. The first connecting frame is hinged to the lower end of the flip assembly. The conveying slide rail is slidably connected to the conveying mechanism. The first motor is tightly connected to the conveying slide rail. The output end of the first motor is tightly connected to the first lead screw. The first lead screw is rotatably connected to the conveying slide rail. The first lead screw is threadedly connected to the conveying mechanism.

[0008] The two groups of supporting mechanisms are respectively located on the two groups of bottom plates, and the two groups of transmission slide rails are symmetrically placed on the two groups of bottom plates. The transmission mechanism moves forward and backward by slidingly connecting with the transmission slide rails. The first motor is fixed on the transmission slide rail. The first motor outputs torque to drive the first lead screw to rotate. The first lead screw and the transmission mechanism convert the torque into linear displacement through a threaded connection. The first connecting frame is fixed through the bottom plate, and the first connecting frame rotatably supports the lower end of the flip assembly. When the flip assembly outputs displacement, the flip assembly can rotate relative to the bottom plate.

[0009] Furthermore, the supporting mechanism includes a column, a lifting frame, a supporting ring, a second lead screw and a second motor. The column and the base plate are fastened together, the column and the second motor are fastened together, the output end of the second motor is fastened together, the second lead screw and the column are rotatably connected, a first threaded groove is provided on the lifting frame, the second lead screw and the lifting frame are threadedly connected, the lifting frame and the column are slidably connected, the lifting frame and the supporting ring are fastened together, and the supporting ring and the flipping mechanism are rotatably connected.

[0010] The bottom plate is placed on the ground, and the vertical column is placed on the bottom plate. The vertical column remains fixed, and the second motor is fixed on the vertical column. The second motor outputs torque to drive the second lead screw to rotate. The second lead screw and the lifting frame are thread-connected to convert the torque into linear displacement. The lifting frame slides up and down outside the vertical column. The support ring and the lifting frame are firmly connected, so that the flipping mechanism also moves with the up and down sliding of the lifting frame.

[0011] Further, the flipping mechanism includes a flipping plate, a rotating shaft, a second connecting frame, a translation slide rail, a third lead screw, and a third motor. Two sets of translation slide rails are provided, and the two sets of translation slide rails are respectively located at both ends of the flipping plate. The translation slide rail and the flipping plate are firmly connected. A third motor is provided on one side of the translation slide rail. The output end of the third motor is firmly connected to the third lead screw. The third lead screw is rotatably connected to the translation slide rail. The third lead screw is thread-connected to the baffle mechanism. The flipping plate is firmly connected to the rotating shaft. The rotating shaft is rotatably connected to the support ring. Two sets of second connecting frames are provided, and the two sets of second connecting frames are placed on the same translation slide rail. The second connecting frame is hinged to the upper end of the flipping assembly. The flipping plate is provided with a lifting groove, and the lifting groove is slidably connected to the lifting mechanism.

[0012] The two sets of translation slide rails are placed on the front and back sides of the flipping plate. The third motor is fixed on the translation slide rail. The third motor outputs torque to drive the third lead screw to rotate. The third lead screw and the baffle mechanism are thread-connected to convert the torque into linear displacement, so that the baffle mechanism can translate back and forth on both sides of the flipping mechanism. Through the rotational connection between the rotating shaft and the support ring, and the hinge connection between the upper end of the flipping assembly and the second connecting frame, the flipping mechanism can achieve a 180° flip, thereby driving the precast member to flip together.

[0013] Further, the flipping assembly includes a first hydraulic cylinder and a second hydraulic cylinder. The lower end of the first hydraulic cylinder is hinged to the first connecting frame, the upper end of the first hydraulic cylinder is hinged to the second connecting frame, the lower end of the second hydraulic cylinder is hinged to the first connecting frame, and the upper end of the second hydraulic cylinder is hinged to the second connecting frame.

[0014] By hinging the lower end of the flipping component and the first connecting frame, as well as the upper end of the flipping component and the second connecting frame, the flipping of the flipping mechanism can be achieved. When the upper end of the first hydraulic cylinder is hinged to the second connecting frame, by discharging the liquid in the first hydraulic cylinder, the first hydraulic cylinder contracts, thereby pulling the flipping mechanism to press downward towards the center-of-gravity sensing device. And as the first hydraulic cylinder contracts, the flipping angle of the flipping mechanism becomes larger until it stops after flipping 180°. At the same time, during the flipping process, the second hydraulic cylinder does not make active movement but continuously sucks in liquid as the flipping progresses, so that the second hydraulic cylinder continuously extends until the flipping ends. After the flipping ends, after placing the precast member on the conveying mechanism, the flipping mechanism will flip back 180° to return to its original position. During this reverse flipping process, the movements of the first hydraulic cylinder and the second hydraulic cylinder are opposite to those in the forward flipping process. The second hydraulic cylinder makes active movement, discharges the internal liquid to make a contraction movement, and pulls the flipping mechanism to flip back in the reverse direction. At the same time, the first hydraulic cylinder acts as a follower, sucks in liquid to make a stretching movement until the reverse flipping ends.

[0015] Furthermore, the lifting mechanism includes a lifting block, a fourth lead screw, and a fourth motor. The lifting block is slidably connected to the lifting groove. The fourth motor is fixedly connected to the lifting groove. The output end of the fourth motor is fixedly connected to the fourth lead screw. The lifting groove is rotatably connected to the fourth lead screw. The lifting block is provided with a second thread groove, and the fourth lead screw is threadedly connected to the lifting block.

[0016] The fourth motor is fixed on the lifting groove. The output torque of the fourth motor drives the fourth lead screw to rotate. The fourth lead screw and the lifting block convert the torque into linear displacement through threaded connection, so that the lifting mechanism slides up and down in the lifting groove.

[0017] Furthermore, the baffle mechanism includes a translation slider, a lifting baffle, a lifting slide rail, a lifting lead screw, and a lifting motor. The translation slider is slidably connected to the translation slide rail. The translation slider is provided with a third thread groove. The translation slider is threadedly connected to the third lead screw. The translation slider is fixedly connected to the lifting slide rail. The lifting slide rail is slidably connected to the lifting baffle. The lifting motor is fixedly connected to the lifting slide rail. The output end of the lifting motor is fixedly connected to the lifting lead screw. The lifting lead screw is rotatably connected to the lifting slide rail. The lifting baffle is provided with a fourth thread groove, and the lifting lead screw is threadedly connected to the lifting baffle. The lifting slide rail is provided with a rotating groove, and the rotating groove is rotatably connected to the center-of-gravity sensing device.

[0018] The lifting motor is fixed on the lifting slide rail. The output torque of the lifting motor drives the lifting lead screw to rotate. The lifting lead screw and the lifting baffle are threadedly connected to convert the torque into linear displacement, so that the lifting baffle moves up and down on the lifting slide rail. Through the sliding connection between the translation slider and the translation slide rail, and the fastening connection between the translation slider and the lifting slide rail, the lifting baffle can move left and right along with the translation slider while sliding up and down. When the baffle mechanism flips along with the flipping mechanism, the side of the precast component will press on the center-of-gravity sensing device. As the center of gravity of the precast component shifts, the center-of-gravity sensing device will rotate left and right.

[0019] Further, the conveying mechanism includes conveying grooves. There are two conveying grooves, which are respectively located at both ends of the conveying mechanism. The conveying grooves are slidably connected to the conveying slide rails. The conveying mechanism is provided with a fifth thread groove, and the fifth thread groove is threadedly connected to the first lead screw.

[0020] Through the sliding connection between the conveying grooves and the conveying slide rails, the conveying mechanism will slide back and forth. After the precast component reaches the plate surface, the conveying mechanism drives the precast component to slide out of the range of the flipping mechanism, so that the precast component leaves the flipping device.

[0021] Further, the center-of-gravity sensing device includes a pressure sensing block and electrodes. The rotation plane of the pressure sensing block is perpendicular to the flipping plane of the flipping plate. The pressure sensing block is rotatably connected to the rotating groove. The pressure sensing block is provided with a sensing block groove, and two groups of electrodes are arranged in the sensing block groove. The two groups of electrodes are arranged on the same side in the sensing block groove.

[0022] The center-of-gravity sensing device is used to measure the center-of-gravity position of the precast component. After the baffle mechanism is displaced to the center-of-gravity position, the precast component can be flipped more smoothly and safely. Since the precast component is of an asymmetric structure and has different centers of gravity, during adjustment, the third motor drives the lifting baffle to move to the center position, and then the first hydraulic cylinder drives the flipping plate to rotate a certain angle, such as rotating about 5° - 10°. The precast component slides down along the surface of the flipping plate under the action of gravity and abuts against the pressure sensing block. Due to the deviation of the center of gravity of the precast component, the pressure sensing block is driven to rotate. For example, when the center of gravity of the precast component is located near the first hydraulic cylinder, the electrolyte between the two electrodes increases, so that the resistance of the detection circuit formed between the electrodes and the power supply decreases. Under the condition of a certain power supply voltage, the circuit current value increases. By the output torque of the third motor, the third lead screw is driven to rotate, and the torque is converted into linear displacement, so as to drive the lifting baffle to move towards the first hydraulic cylinder until it moves to the center-of-gravity position of the component, and the current value tends to be stable. When the center of gravity of the precast component is located near the second hydraulic cylinder, the lifting baffle moves towards the second hydraulic cylinder.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: The prefabricated component is first placed on the flipping mechanism. Since the bottom of the prefabricated component is not necessarily flat, the lifting mechanism adjacent to the flipping mechanism rises to support one side bottom of the prefabricated component, making the upper surface of the prefabricated component tend to be horizontal. Before flipping, the baffle mechanism first slides to the middle end of the flipping mechanism, and then the flipping mechanism is flipped by a certain angle, so that the side surface of the prefabricated component presses on the center-of-gravity sensing device. The baffle mechanism is translated to the position where the center of gravity of the prefabricated component is balanced through the center-of-gravity sensing device, and then a complete 180° flip is carried out. After flipping, the flipping mechanism descends close to the conveying mechanism through the lifting frame, places the prefabricated component on the surface of the conveying mechanism, and finally the conveying mechanism drives the flipped prefabricated component to slide out of the range of the flipping mechanism, and the flipped prefabricated component thus leaves the flipping device. By integrally arranging the flap structure and arranging it vertically, the space utilization rate is improved and the floor area is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Embodiment: As Figures 1 - 9 shown, the present invention provides a technical solution for a flipping device for precast components with an adaptive function.

[0028] As Figure 1 shown, a flipping device for precast components with an adaptive function, the flipping device includes a base 1, a support mechanism 2, a flipping assembly 3, a flipping mechanism 4, a lifting mechanism 5, a baffle mechanism 6, a conveyor mechanism 7 and a center of gravity sensing device 8. The base 1 and the support mechanism 2 are fixedly connected. There are two groups of support mechanisms 2, and the two groups of support mechanisms 2 are respectively located on both sides of the base 1. The base 1 and the lower end of the flipping assembly 3 are hinged. The base 1 and the conveyor mechanism 7 are threadedly connected. The support mechanism 2 and the flipping mechanism 4 are rotatably connected. The flipping mechanism 4 and the baffle mechanism 6 are threadedly connected. The upper end of the flipping mechanism 4 and the flipping assembly 3 are hinged. The flipping mechanism 4 and the lifting mechanism 5 are slidably connected. The baffle mechanism 6 and the center of gravity sensing device 8 are rotatably connected.

[0029] There are two groups of supporting mechanisms 2 on both sides of the base 1, and the two groups of supporting mechanisms 2 support the flipping mechanism 4 at the same time. The flipping assembly 3 is rotatably connected to the base 1, and the flipping assembly 3 is rotatably connected to the flipping mechanism 4. The flipping assembly 3 flips the flipping mechanism 4 180° by rotating back and forth. The prefabricated component is placed on the flipping mechanism 4, so the prefabricated component will flip along with the flipping mechanism 4. When the prefabricated component is placed on the flipping mechanism 4, since the bottom of the prefabricated component is not necessarily flat, the lifting mechanism 5 rises to resist the bottom of one side of the prefabricated component to achieve balance. Before flipping, the baffle mechanism 6 first slides to the flipping mechanism 4. The middle end of the rotating mechanism 4 is then flipped at a certain angle so that the side of the prefabricated component is pressed on the center of gravity sensing device 8, and the baffle mechanism 6 is translated to the position where the center of gravity of the prefabricated component is balanced through the center of gravity sensing device 8, and then a complete 180° flip is performed. After flipping, the flipping mechanism 4 descends and approaches the conveying mechanism 7. After the conveying mechanism 7 catches the prefabricated component and stabilizes, the baffle mechanism 6 is translated to the sidemost side of the flipping mechanism 4, and the conveying mechanism 7 can slide on the base 1. The conveying mechanism 7 drives the flipped prefabricated component to slide out of the front end of the base 1, and the flipped prefabricated component can be transferred away.

[0030] like Figures 1 - 3 As shown, the base 1 includes a bottom plate 11, a conveying slide rail 12, a first lead screw 13, a first motor 14 and a first connecting frame 15. The bottom plate 11 is tightly connected to the support mechanism 2. Two groups of bottom plates 11 are arranged. The two groups of bottom plates 11 are respectively located on both sides of the conveying mechanism 7. The conveying slide rail 12 is arranged on the bottom plate 11. The first connecting frame 15 is arranged on the bottom plate 11. The two first connecting frames 15 are respectively placed on both sides of the support mechanism 2. The first connecting frame 15 and the lower end of the flip assembly 3 are hinged. The conveying slide rail 12 and the conveying mechanism 7 are slidably connected. The first motor 14 and the conveying slide rail 12 are tightly connected. The output end of the first motor 14 and the first lead screw 13 are tightly connected. The first lead screw 13 and the conveying slide rail 12 are rotatably connected. The first lead screw 13 and the conveying mechanism 7 are threadedly connected.

[0031] The two groups of supporting mechanisms 2 are respectively located on the two groups of bottom plates 11, and the two groups of conveying slide rails 12 are symmetrically placed on the two groups of bottom plates 11. The conveying mechanism 7 moves forward and backward by slidingly connecting with the conveying slide rails 12. The first motor 14 is fixed on the conveying slide rails 12. The first motor 14 outputs torque to drive the first lead screw 13 to rotate. The first lead screw 13 and the conveying mechanism 7 are threadedly connected to convert the torque into linear displacement. The first connecting frame 15 is fixed by the bottom plate 11, and the first connecting frame 15 rotatably supports the lower end of the flipping assembly 3. When the flipping assembly 3 outputs displacement, the flipping assembly 3 can rotate relative to the bottom plate 11.

[0032] like Figures 1 - 2As shown, the support mechanism 2 includes a column 21, a lifting frame 22, a support ring 23, a second lead screw 24, and a second motor 25. The column 21 is fixedly connected to the bottom plate 11. The column 21 is fixedly connected to the second motor 25. The output end of the second motor 25 is fixedly connected to the second lead screw 24. The second lead screw 24 is rotatably connected to the column 21. The lifting frame 22 is provided with a first thread groove. The second lead screw 24 is threadedly connected to the lifting frame 22. The lifting frame 22 is slidably connected to the column 21. The lifting frame 22 is fixedly connected to the support ring 23. The support ring 23 is rotatably connected to the flipping mechanism 4.

[0033] The bottom plate 11 is placed on the ground. The column 21 is placed on the bottom plate 11 and remains fixed. The second motor 25 is fixed on the column 21. The output torque of the second motor 25 drives the second lead screw 24 to rotate. The second lead screw 24 and the lifting frame 22 convert the torque into linear displacement through threaded connection. The lifting frame 22 slides up and down outside the column 21. The support ring 23 is fixedly connected to the lifting frame 22. Thus, the flipping mechanism 4 also moves along with the up and down sliding of the lifting frame 22.

[0034] As Figures 4 - 6 shown, the flipping mechanism 4 includes a flipping plate 41, a rotating shaft 42, a second connecting frame 43, a translation slide rail 44, a third lead screw 45, and a third motor 46. Two sets of translation slide rails 44 are provided. The two sets of translation slide rails 44 are respectively located at both ends of the flipping plate 41. The translation slide rail 44 is fixedly connected to the flipping plate 41. A third motor 46 is provided on one side of the translation slide rail 44. The output end of the third motor 46 is fixedly connected to the third lead screw 45. The third lead screw 45 is rotatably connected to the translation slide rail 44. The third lead screw 45 is threadedly connected to the baffle mechanism 6. The flipping plate 41 is fixedly connected to the rotating shaft 42. The rotating shaft 42 is rotatably connected to the support ring 23. Two sets of second connecting frames 43 are provided. The two sets of second connecting frames 43 are placed on the same translation slide rail 44. The second connecting frame 43 is hinged to the upper end of the flipping assembly 3. The flipping plate 41 is provided with a lifting groove 411. The lifting groove 411 is slidably connected to the lifting mechanism 5.

[0035] The two sets of translation slide rails 44 are placed on the front and back sides of the flipping plate 41. The third motor 46 is fixed on the translation slide rail 44. The output torque of the third motor 46 drives the third lead screw 45 to rotate. The third lead screw 45 and the baffle mechanism 6 convert the torque into linear displacement through threaded connection. Thus, the baffle mechanism 6 can translate back and forth on both sides of the flipping mechanism 4. Through the rotational connection between the rotating shaft 42 and the support ring 23, and the hinge between the upper end of the flipping assembly 3 and the second connecting frame 43, the flipping mechanism 4 can achieve a 180° flip, thereby driving the precast member to flip together.

[0036] As Figure 4As shown, the flipping assembly 3 includes a first hydraulic cylinder 31 and a second hydraulic cylinder 32. The lower end of the first hydraulic cylinder 31 is hinged to the first connecting frame 15, the upper end of the first hydraulic cylinder 31 is hinged to the second connecting frame 43, the lower end of the second hydraulic cylinder 32 is hinged to the first connecting frame 15, and the upper end of the second hydraulic cylinder 32 is hinged to the second connecting frame 43.

[0037] Through the hinge connection between the lower end of the flipping assembly 3 and the first connecting frame 15, and the hinge connection between the upper end of the flipping assembly 3 and the second connecting frame 43, the flipping of the flipping mechanism 4 can be achieved. When the upper end of the first hydraulic cylinder 31 is hinged to the second connecting frame 43, by discharging the liquid in the first hydraulic cylinder 31, the first hydraulic cylinder 31 contracts, thereby pulling the flipping mechanism 4 to press downward toward the gravity sensing device 8. And as the first hydraulic cylinder 31 contracts, the flipping angle of the flipping mechanism 4 becomes larger until it stops after flipping 180°. At the same time, during the flipping process, the second hydraulic cylinder 32 does not make an active movement, but continuously sucks in liquid as the flipping progresses, so that the second hydraulic cylinder 32 continuously elongates until the flipping ends. After the flipping ends, after placing the precast member on the conveying mechanism 7, the flipping mechanism 4 will flip back 180° to return to its original position. During this reverse flipping process, the movements of the first hydraulic cylinder 31 and the second hydraulic cylinder 32 are opposite to those in the forward flipping process. The second hydraulic cylinder 32 makes an active movement, discharges the internal liquid and makes a contraction movement, pulling the flipping mechanism 4 to flip back in the reverse direction. At the same time, the first hydraulic cylinder 31 acts as a follower, sucks in liquid and stretches until the reverse flipping ends.

[0038] As Figure 5 shown, the lifting mechanism 5 includes a lifting block 51, a fourth lead screw 52 and a fourth motor 53. The lifting block 51 is slidably connected to the lifting groove 411. The fourth motor 53 is fixedly connected to the lifting groove 411. The output end of the fourth motor 53 is fixedly connected to the fourth lead screw 52. The lifting groove 411 is rotatably connected to the fourth lead screw 52. The lifting block 51 is provided with a second thread groove, and the fourth lead screw 52 is threadedly connected to the lifting block 51.

[0039] The fourth motor 53 is fixed on the lifting groove 411. The output torque of the fourth motor 53 drives the fourth lead screw 52 to rotate. The fourth lead screw 52 and the lifting block 51 convert the torque into linear displacement through threaded connection, so that the lifting mechanism 5 slides up and down in the lifting groove 411.

[0040] As Figures 6 - 8As shown in the figure, the baffle mechanism 6 includes a translation slider 61, a lifting baffle 62, a lifting slide rail 63, a lifting lead screw 64, and a lifting motor 65. The translation slider 61 is slidably connected to the translation slide rail 44. The translation slider 61 is provided with a third thread groove and is threadedly connected to the third lead screw 45. The translation slider 61 is fixedly connected to the lifting slide rail 63. The lifting slide rail 63 is slidably connected to the lifting baffle 62. The lifting motor 65 is fixedly connected to the lifting slide rail 63. The output end of the lifting motor 65 is fixedly connected to the lifting lead screw 64. The lifting lead screw 64 is rotatably connected to the lifting slide rail 63. The lifting baffle 62 is provided with a fourth thread groove, and the lifting lead screw 64 is threadedly connected to the lifting baffle 62. The lifting slide rail 63 is provided with a rotating groove 631, and the rotating groove 631 is rotatably connected to the center-of-gravity sensing device 8.

[0041] The lifting motor 65 is fixed on the lifting slide rail 63. The output torque of the lifting motor 65 drives the lifting lead screw 64 to rotate. The lifting lead screw 64 and the lifting baffle 62 convert the torque into a linear displacement through threaded connection, so that the lifting baffle 62 moves up and down on the lifting slide rail 63. Through the sliding connection between the translation slider 61 and the translation slide rail 44, and the fixed connection between the translation slider 61 and the lifting slide rail 63, the lifting baffle 62 can move left and right along with the translation slider 61 while sliding up and down. When the baffle mechanism 6 rotates with the flipping mechanism 4, the side of the precast member will press on the center-of-gravity sensing device 8. As the center of gravity of the precast member shifts, the center-of-gravity sensing device 8 will rotate left and right.

[0042] As Figure 9 shown in the figure, the conveying mechanism 7 includes conveying grooves 71. There are two conveying grooves 71, which are respectively located at both ends of the conveying mechanism 7. The conveying grooves 71 are slidably connected to the conveying slide rails 12. The conveying mechanism 7 is provided with a fifth thread groove, and the fifth thread groove is threadedly connected to the first lead screw 13.

[0043] Through the sliding connection between the conveying grooves 71 and the conveying slide rails 12, the conveying mechanism 7 will slide back and forth. After the precast member reaches the plate surface, the conveying mechanism 7 drives the precast member to slide out of the range of the flipping mechanism 4, so that the precast member leaves the flipping device.

[0044] As Figure 8 shown in the figure, the center-of-gravity sensing device 8 includes a pressure sensing block 81 and electrodes 82. The rotation plane of the pressure sensing block 81 is perpendicular to the flipping plane of the flipping plate 41. The pressure sensing block 81 is rotatably connected to the rotating groove 631. The pressure sensing block 81 is provided with a sensing block groove 811, and two groups of electrodes 82 are arranged in the sensing block groove 811. The two groups of electrodes 82 are arranged on the same side in the sensing block groove 811.

[0045] The center-of-gravity sensing device 8 is used to measure the center-of-gravity position of the precast component. After the baffle mechanism 6 is displaced to the center-of-gravity position, the precast component can be turned over more smoothly and safely. Since the precast component is an asymmetric structure with different centers of gravity, during adjustment, the third motor 46 drives the lifting baffle 62 to move to the center position, and then the first hydraulic cylinder 31 drives the turning plate 41 to rotate a certain angle, such as about 5°-10°. The precast component slides downward along the surface of the turning plate 41 under the action of gravity and abuts against the pressure sensing block 81. Due to the deviation of the center of gravity of the precast component, the pressure sensing block 81 is driven to rotate. For example, when the center of gravity of the precast component is located close to the first hydraulic cylinder 31, the electrolyte between the two electrodes 82 increases, so that the resistance of the detection circuit formed between the electrode 82 and the power supply decreases. When the power supply voltage is constant, the circuit current value increases. By the output torque of the third motor 46, the third lead screw 45 is driven to rotate, and the torque is converted into linear displacement, so as to drive the lifting baffle 62 to move towards the first hydraulic cylinder 31 until it moves to the center-of-gravity position of the component, and the current value tends to be stable. When the center of gravity of the precast component is located close to the second hydraulic cylinder 32, the lifting baffle 62 moves towards the second hydraulic cylinder 32.

[0046] The working principle of the present invention: The precast component is first placed on the turning mechanism 4. Since the bottom of the precast component is not necessarily flat, the adjacent lifting mechanism 5 rises to abut against one side bottom of the precast component, making the upper surface of the precast component tend to be horizontal. Before turning over, the baffle mechanism 6 first slides to the middle end of the turning mechanism 4, and then the turning mechanism 4 is turned over by a certain angle, so that the side surface of the precast component presses on the center-of-gravity sensing device 8. The baffle mechanism 6 is translated to the position where the center of gravity of the precast component is balanced through the center-of-gravity sensing device 8, and then a complete 180° turn is carried out. After turning over, the turning mechanism 4 descends close to the conveying mechanism 7 through the lifting frame 22, places the precast component on the surface of the conveying mechanism 7, and finally the conveying mechanism 7 drives the turned-over precast component to slide out of the range of the turning mechanism 4, and the turned-over precast component thus leaves the turning device. By integrally arranging the turning plate structure and arranging it vertically, the space utilization rate is improved and the floor area is reduced.
