Description

Technical Field

[0001] This invention belongs to the field of construction equipment technology, and specifically relates to a flipping device for irregularly shaped PC components. Background Technology

[0002] Irregularly shaped PC components, such as PC wall panels with external windows, need to go through multiple processes after being cast in the prefabrication plant before being placed in the designated storage location on the construction site and then hoisted by hoisting equipment. However, due to the unbalanced stress of irregularly shaped PC components, their position during storage is often different from their position during hoisting, making direct hoisting risky. Therefore, it is necessary to flip the irregularly shaped PC components before hoisting. Summary of the Invention

[0003] In view of this, the present invention discloses a flipping device for irregularly shaped PC components, the purpose of which is to solve the problem that irregularly shaped PC components need to be flipped before hoisting.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A flipping device for irregularly shaped PC components includes a rectangular support frame. Support rods are fixed at the bottom of each of the four corners of the support frame. Slide seats are slidably connected to both sides of the top of the support frame along its length. Each slide seat is equipped with a first power structure for driving its sliding. An upper sliding frame is fixed between two slide seats. Two mounting seats are symmetrically arranged at both ends of the upper sliding frame and slidably connected along its length. Locking pins are provided between the mounting seats and the upper sliding frame. A main lifting device is provided on each mounting seat. The output end of each main lifting device is connected to a horizontally arranged bracket. Support shafts parallel to the upper sliding frame are rotatably connected to the opposing ends of the two brackets. Clamps for connecting irregularly shaped PC components are rotatably connected to the ends of the support shafts. A drive device for driving the support shafts to rotate is provided on the brackets.

[0005] In this scheme, the sliding block is driven by the first power structure to slide and slide the mounting base, so that the clamp is close to both ends of the flipping axis of the irregular PC component. After the mounting base is locked by the locking pin, the clamp is connected to both ends of the irregular PC component. The irregular PC component is lifted by the main lifting device to a certain distance, ensuring that the distance between the irregular PC component and the ground is sufficient to accommodate the flipping of the irregular PC component. The support shaft is driven by the drive device, and then the support shaft and the clamp are used to drive the irregular PC component to flip. After flipping, the irregular PC component is lifted again by the main lifting device until it is lifted to the required height. Then the sliding block is driven by the first power structure to drive the irregular PC component to move horizontally.

[0006] Furthermore, an adjusting frame is fixed at the bottom of the upper sliding frame, horizontally perpendicular to the upper sliding frame. A groove is provided on one side of the adjusting frame, and an adjusting seat is slidably connected within the groove. The adjusting seat is equipped with a second power structure for driving its sliding, and an auxiliary lifting device is provided on the adjusting seat. The output end of the auxiliary lifting device is connected to a support detachably connected to the irregularly shaped PC component. A horizontal bar parallel to the adjusting frame is fixed between the bottoms of adjacent support rods along the length of the support frame. A lower sliding frame is provided between two horizontal rods along the length of the horizontal rod. A third power structure for driving its sliding is provided on the lower sliding frame. A hydraulic rod is vertically arranged on the lower sliding frame, and the top of the hydraulic rod is also hinged to a support detachably connected to the irregularly shaped PC component. In this solution, after the clamp is connected to the irregularly shaped PC component, the second power structure drives the adjusting seat to adjust the position of the auxiliary lifting device above the upward-flipping end of the irregularly shaped PC component. The support at the output end of the auxiliary lifting device is connected to the corresponding end of the irregularly shaped PC component, and the main lifting device and the auxiliary lifting device simultaneously lift the irregularly shaped PC component. If there is sufficient space under the irregularly shaped PC component before lifting, the third power structure drives the lower sliding frame to move the hydraulic rod to the other end of the irregularly shaped PC component, and the support at the end of the hydraulic rod is connected to the corresponding end of the irregularly shaped PC component. If there is insufficient space under the irregularly shaped PC component before lifting, the support at the end of the hydraulic rod is connected to the end of the irregularly shaped PC component after the irregularly shaped PC component has been lifted to a certain height. When the drive device drives the support shaft to rotate the irregularly shaped PC component, the second and third power structures drive the hydraulic rod and the auxiliary lifting device to move towards each other. During the movement, the auxiliary lifting device is extended and retracted, and the hydraulic rod is extended and retracted, thereby assisting in the rotation of the irregularly shaped PC component and preventing excessive force concentration on the clamp and the irregularly shaped PC component, which could cause damage to the clamp and the irregularly shaped PC component.

[0007] Furthermore, the clamp includes a base fixedly connected to the end of the support shaft. Several vertically arranged grooves are formed on the end face of the base away from the bracket. A positioning seat is slidably connected in each groove. A screw is coaxially rotatably connected in each groove. The screw passes through the corresponding positioning seat and is threadedly connected to it. A clamping plate that extends horizontally out of the positioning seat is fixed on each positioning seat. Adjacent clamping plates are staggered.

[0008] In this solution, the clamping plates on the fixture are clamped on the upper and lower sides of the irregular PC component. By driving the screw to rotate forward or backward, the clamping plates on the upper and lower sides of the irregular PC component are moved to fit the irregular PC component. By clamping the two sides of the irregular PC component with multiple clamping plates, the fixture can adapt to various types of irregular PC components.

[0009] Furthermore, both ends of the support frame are provided with slots for the adjustment bracket to extend out.

[0010] Furthermore, several diagonal braces are provided above the horizontal bar, and the two ends of the diagonal braces are fixedly connected to the corresponding support rods.

[0011] Furthermore, each of the support rods is equipped with casters at its bottom.

[0012] Furthermore, the clamping plate is provided with a rubber pad layer.

[0013] Other advantages, objectives, and features of the invention will be set forth in the following description and will be apparent to those skilled in the art in some respects, or may be learned by practice of the invention. The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

[0016] like Figures 1-3 As shown: A flipping device for irregularly shaped PC components includes a rectangular support frame 1. Support rods 2 are fixed to the bottom of each of the four corners of the support frame 1. Slide seats 3 are slidably connected to both sides of the top of the support frame 1 along its length. Each slide seat 3 is provided with a first power structure for driving its sliding (in this embodiment, a motor drive is used, which is conventional technology and therefore not described in detail or shown in the figure). An upper sliding frame 4 is fixed between two slide seats 3. Two mounting seats 5 are symmetrically arranged at both ends of the upper sliding frame 4 and are slidably connected to it along its length. Each mounting base 5 is equipped with a locking pin 6. Each mounting base 5 is equipped with a main lifting device 7 (a winch is used in this embodiment, which is a conventional technology and is not described in detail). The output end of each main lifting device 7 is connected to a horizontally arranged bracket 8. The opposing ends of the two brackets 8 are rotatably connected to a support shaft 15 parallel to the upper sliding frame 4. The end of each support shaft 15 is rotatably connected to a clamp for connecting the irregular PC component 24. Each bracket 8 is equipped with a driving device for driving the support shaft 15 to rotate (a motor drive is used in this embodiment, which is a conventional technology and is not described in detail and is not shown in the figure).

[0017] In this scheme, the slide block 3 is driven to slide by the first power structure, and the mounting base 5 is slid to bring the clamp close to both ends of the flipping axis of the irregular PC component 24. After the mounting base 5 is locked by the locking pin 6, the clamp is connected to both ends of the irregular PC component 24. The irregular PC component 24 is lifted by the main lifting device 7 to a certain distance, ensuring that the distance between the irregular PC component 24 and the ground is sufficient to accommodate the flipping of the irregular PC component 24. The support shaft 15 is driven by the driving device, and then the irregular PC component 24 is flipped by the support shaft 15 and the clamp. After flipping, the irregular PC component 24 is lifted again by the main lifting device 7 until it is lifted to the required height. Then the slide block 3 is driven by the first power structure to drive the irregular PC component 24 to move horizontally.

[0018] Furthermore, an adjusting frame 9, horizontally perpendicular to the bottom of the upper sliding frame 4, is fixed to the bottom of the upper sliding frame 4. A sliding groove is provided on one side of the adjusting frame 9, and an adjusting seat 10 is slidably connected within the groove. The adjusting seat 10 is equipped with a second power structure for driving its sliding (in this embodiment, a motor drive is used, which is conventional technology and therefore not described in detail or shown in the figure). An auxiliary lifting device 11 is provided on the adjusting seat 10 (in this embodiment, a winch is used, which is conventional technology and therefore not described in detail). The output end of the auxiliary lifting device 11 is connected to the irregularly shaped PC component 24. A detachable support 12 is provided; horizontal rods 13 parallel to the adjusting frame 9 are fixed between the bottoms of adjacent support rods 2 along the length direction of the support frame 1. A lower sliding frame 14 along the length direction of the horizontal rod 13 is provided between the two horizontal rods 13. The lower sliding frame 14 is provided with a third power structure for driving its sliding (in this embodiment, a motor drive is used, which is a conventional technology, so it is not described in detail and is not shown in the figure). A hydraulic rod 21 is vertically provided on the lower sliding frame 14. The top of the hydraulic rod 21 is also hinged to a support 12 that is detachably connected to the irregular PC component 24. In this scheme, after the clamp is connected to the irregular PC component 24, the second power structure drives the adjusting seat 10 to adjust the position of the auxiliary lifting device 11 above the upward flipping end of the irregular PC component 24. The support 12 at the output end of the auxiliary lifting device 11 is connected to the corresponding end of the irregular PC component 24. The main lifting device 7 and the auxiliary lifting device 11 simultaneously lift the irregular PC component 24. If there is enough space under the irregular PC component 24 before lifting, the third power structure drives the lower sliding frame 14 to move the hydraulic rod 21 to the other end of the irregular PC component 24, and the support 12 at the end of the hydraulic rod 21 is connected to the corresponding end of the irregular PC component 24. If there is not enough space under the irregular PC component 24 before lifting, the support 12 at the end of the hydraulic rod 21 is connected to the end of the irregular PC component 24 after the irregular PC component 24 is lifted to a certain height.

[0019] When the drive device drives the support shaft 15 to rotate the irregular PC component 24, the hydraulic rod 21 and the auxiliary lifting device 11 are driven to move towards each other through the second power structure and the third power structure. During the movement, the auxiliary lifting device 11 is synchronously wound up and the hydraulic rod 21 is contracted, thereby assisting the rotation of the irregular PC component 24. After the irregular PC component 24 has completed a 90-degree rotation, the auxiliary lifting device 11 is unwound and the hydraulic rod 21 is extended. The auxiliary lifting device 11 and the hydraulic rod 21 apply corresponding forces to both ends of the irregular PC component 24 to avoid excessive force concentration on the clamp and the irregular PC component 24, which could cause damage to the clamp and the irregular PC component 24.

[0020] Furthermore, the clamp includes a seat 16 fixedly connected to the end of the support shaft 15. The end face of the seat 16 away from the bracket 8 is provided with several vertically arranged grooves. A positioning seat 17 is slidably connected in each groove. A screw 18 is coaxially rotatably connected in each groove. The screw 18 passes through the corresponding positioning seat 17 and is threadedly connected to it. A clamping plate 19 is fixed on each positioning seat 17, extending horizontally out of the positioning seat 17. Adjacent clamping plates 19 are staggered.

[0021] In this solution, the clamping plates 19 on the fixture are clamped on the upper and lower sides of the irregular PC component 24. By driving the screw 18 to rotate in the forward or reverse direction, the clamping plates 19 on the upper and lower sides of the irregular PC component 24 are moved to fit the irregular PC component 24. By clamping the two sides of the irregular PC component 24 with multiple clamping plates 19, the fixture can adapt to various types of irregular PC components 24.

[0022] Furthermore, both ends of the support frame 1 are provided with slots 20 for the adjustment frame 9 to extend out.

[0023] The hoisting device in this scheme is suitable for low-altitude hoisting. After the irregular PC component 24 is hoisted and flipped at low altitude, part of the hoisting equipment is connected to both sides of the irregular PC component 24 and the end connected to the auxiliary lifting equipment 11. The clamps and the corresponding supports 12 of the auxiliary lifting equipment 11 are removed. The slide block 3 is driven by the first drive structure, so that the hoisting equipment and the adjusting frame 9 on the lower sliding frame 14 are moved to one end of the support frame 1. The slot 20 facilitates the extension of one end of the adjusting frame 9, preventing the upper sliding frame 4 and the adjusting frame 9 from obstructing the hoisting of the irregular PC component 24 at high altitude. After connecting part of the hoisting equipment to the other end of the irregular PC component 24, the connection between the support 12 on the hydraulic rod 21 and the irregular PC component 24 is removed. At this time, high-altitude hoisting can be carried out.

[0024] Furthermore, a plurality of diagonal bracing rods 22 are provided above the horizontal rod 13, and the two ends of the diagonal bracing rods 22 are respectively fixedly connected to the corresponding support rods 2.

[0025] The overall strength of the hoisting device is enhanced by setting diagonal bracing rods 22.

[0026] Furthermore, each of the support rods 2 is equipped with a caster wheel 23 at its bottom.

[0027] The casters 23 facilitate the movement of the entire hoisting device; when hoisting operations are performed, the casters 23 are locked. The locking of the casters 23 is a conventional technical means, so it is not described in detail.

[0028] Furthermore, the clamping plate 19 is provided with a rubber pad layer.

[0029] By setting a rubber pad layer, the damage to the irregular PC component 24 by the clamping plate 19 is reduced.

[0030] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
