Description

Technical Field

[0001] This utility model relates to the field of precast component processing, and more specifically, it relates to a clamping and flipping device for precast concrete components. Background Technology

[0002] Precast concrete components are concrete components that are prefabricated in a factory, such as pipe piles, wall panels, and stairs. During the production of precast components, they need to go through a variety of processing steps such as grinding and grooving. Stable and reliable clamping of precast components is a key link to ensure processing accuracy, production efficiency and operational safety.

[0003] The patent with publication number CN220362770U discloses a flipping device for prefabricated part processing, including a base, a processing table is provided on the upper side of the base, a U-shaped movable seat is movably installed on the upper end of the base on one side of the processing table, a pushing component is connected to one side of the U-shaped movable seat, a swinging component is installed on the U-shaped movable seat, a flipping component is installed on the swinging component, and a clamping component is installed on the flipping component; the pushing component includes a first hydraulic cylinder fixed to the upper end of the base, and one end of the first hydraulic cylinder is connected to the bottom side of one side of the U-shaped movable seat.

[0004] The flipping device in the above scheme can effectively prevent the precast block from colliding with the processing table and prevent damage to the component through the coordinated operation of the swing component, flipping component, clamping component and pushing component. However, when the clamping component clamps the precast part, it mainly lifts and flips the precast part by the friction of clamping. If the clamping force is too small, the precast part may slide off the clamping component during the lifting process. If the clamping force is too large, the precast part may be damaged by the clamping component. Setting the clamping force takes a long time and is quite troublesome.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a clamping and flipping device for precast concrete components. When clamping precast components, the device can clamp the components from all directions through the clamping components, preventing the components from moving during processing. Furthermore, it can prevent the components from falling off the clamping components during the flipping process. In this process, there is no need to set the clamping force, making it more convenient and practical.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a clamping and flipping device for precast concrete components includes a support frame, a bidirectional cylinder is fixedly connected to the support frame, a limit block is fixedly connected to both telescopic ends of the bidirectional cylinder, a sliding plate is slidably connected to the limit block, a positioning column is rotatably connected to the sliding plate, a clamping component for clamping the precast component is provided on the positioning column, and a flipping component for flipping the precast component is provided on the positioning column.

[0008] The present invention is further configured such that: the clamping assembly includes a fixing block with two positioning posts fixedly connected at one end close to each other, an electric push rod fixedly connected to both sides of the fixing block, a positioning frame fixedly connected to the telescopic end of the electric push rod, two rotating rods coaxially rotating on the positioning frame, and a positioning block rotatably connected on the rotating rods, with two adjacent positioning blocks arranged on opposite sides, and the positioning block is provided with a limiting member that limits the rotation angle of the positioning block.

[0009] The present invention is further configured such that: the limiting member includes a limiting rod that is slidably connected between two adjacent positioning blocks and a connecting rod that is fixedly connected to the limiting rod, and the connecting rod is slidably connected to the adjacent positioning frame.

[0010] The present invention is further configured such that: the flipping assembly includes an extension block fixedly connected to the sliding plate, a lifting cylinder slidably connected to the extension block, and a positioning ring fixedly connected to the telescopic end of the lifting cylinder; the lifting cylinder is slidably connected to the support frame; a fixing frame is fixedly connected to the positioning ring; a motor is fixedly connected to the fixing frame; and the motor output shaft is fixedly connected to the positioning column.

[0011] The present invention is further configured such that a plurality of spheres are rotatably connected to the support frame.

Detailed Implementation

[0015] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0016] A clamping and flipping device for precast concrete components, such as Figures 1-3 As shown, the device includes a support frame 1, on which a bidirectional cylinder 2 is fixedly connected. Both telescopic ends of the bidirectional cylinder 2 are fixedly connected to limit blocks 3. A sliding plate 4 is slidably connected to the limit blocks 3. A positioning post 5 is rotatably connected to the sliding plate 4. The positioning post 5 is provided with a clamping assembly for clamping the prefabricated component and a flipping assembly for flipping the prefabricated component. The clamping assembly includes a fixed block 6 fixedly connected to one end of the two positioning posts 5, an electric push rod 7 fixedly connected to both sides of the fixed block 6, a positioning frame 8 fixedly connected to the telescopic end of the electric push rod 7, two rotating rods 9 coaxially rotating on the positioning frame 8, and a positioning block 10 rotatably connected to the rotating rods 9. The two adjacent positioning blocks 10 are arranged opposite each other. The positioning block 10 is provided with a limiting member that limits the rotation angle of the positioning block 10. The limiting member includes a limiting rod 11 slidably connected between the two adjacent positioning blocks 10 and a connecting rod 12 fixedly connected to the limiting rod 11. The connecting rod 12 is slidably connected to the adjacent positioning frame 8.

[0017] like Figures 1-3 As shown, when clamping the precast component during precast component processing, the precast component is first placed on the support frame 1. Then, the flipping assembly is activated to move the fixing block 6 to the center position of the precast component (i.e., half the height of the precast component). At this time, the sliding plate 4 will slide on the limiting block 3. Then, the bidirectional cylinder 2 can be activated to retract, causing the two sliding plates 4 to move closer to each other, and then causing the two fixing blocks 6 to move closer to each other and fit against the precast component. Next, the electric push rod 7 can be activated to retract, causing the positioning frame 8, rotating rod 9, positioning block 10, limiting rod 11, and connecting rod 12 to move. When the limiting rod 11 and the connecting rod 12 move, the connecting rod 12 will move. When the preform comes into contact, the limiting rod 11 will be unable to move further, and the positioning block 10 and connecting rod 12 will be restricted by the limiting rod 11 and unable to move. Then the electric push rod 7 continues to retract, and the positioning frame 8 and rotating rod 9 will continue to move under the drive of the electric push rod 7. At this time, the positioning frame 8 will slide on the limiting rod 11, and the two positioning blocks 10 will be pulled by the two rotating rods 9 to slide on the limiting rod 11 and move closer to each other to clamp the preform. After clamping, the processing operation can be performed. When it is necessary to process the reverse side of the preform, the flipping component can be activated to flip the preform for reverse processing.

[0018] like Figures 1-2 As shown, the flipping assembly includes an extension block 13 fixedly connected to the sliding plate 4, a lifting cylinder 14 slidably connected to the extension block 13, and a positioning ring 15 fixedly connected to the telescopic end of the lifting cylinder 14. The lifting cylinder 14 is slidably connected to the support frame 1. A fixing frame 16 is fixedly connected to the positioning ring 15, and a motor 17 is fixedly connected to the fixing frame 16. The output shaft of the motor 17 is fixedly connected to the positioning column 5. When it is necessary to move the fixing block 6 to the center position of the precast part, the lifting cylinder 14 can be activated to extend and drive the positioning ring 15 and the positioning column 5 to move upward, thereby driving the fixing block 6 to move. After clamping is complete, the lifting cylinder 14 can be activated again to extend to its longest position. At this time, the positioning ring 15, positioning column 5, fixing block 6 move upward, and the electric push rod 7, positioning frame 8, rotating rod 9 and positioning block 10 will also be driven to move upward. Since the precast part is clamped by the positioning block 10, the precast part will also be driven to move upward by the lifting cylinder 14. Then, the motor 17 is activated to drive the positioning column 5 and positioning block 10 to rotate and flip the precast part. After flipping, the lifting cylinder 14 is activated again to retract. When the precast part is in contact with the support frame 1, the flipping is considered complete.

[0019] like Figures 1-2 As shown, several spheres 18 are rotatably connected to the support frame 1, which allows for easy fine-tuning of the position of the precast component after it has been placed.

[0020] Working principle: When clamping the precast component during precast component processing, the precast component is first placed on several spheres 18 of the support frame 1 and its position is finely adjusted. Then, the lifting cylinder 14 is activated to extend and move the fixing block 6 to the center position of the precast component. At this time, the sliding plate 4 will slide on the limit block 3. Then, the bidirectional cylinder 2 can be activated to retract, causing the two sliding plates 4 to move closer to each other, and then causing the two fixing blocks 6 to move closer to each other and fit against the precast component. Then, the electric push rod 7 can be activated to retract and drive the positioning frame 8, rotating rod 9, and positioning block 10. The limiting rod 11 and connecting rod 12 move. When the limiting rod 11 contacts the preform, the limiting rod 11 will be unable to move further, while the positioning block 10 and connecting rod 12 will be restricted by the limiting rod 11 and unable to move. Subsequently, the electric push rod 7 continues to retract, and the positioning frame 8 and rotating rod 9 will continue to move under the drive of the electric push rod 7. At this time, the positioning frame 8 will slide on the limiting rod 11, and the two positioning blocks 10 will be pulled by the two rotating rods 9 to slide on the limiting rod 11 and move closer to each other to clamp the preform. After clamping, the processing operation can be performed.

[0021] When it is necessary to process the reverse side of the preform, the lifting cylinder 14 can be activated to extend and drive the positioning ring 15 and positioning column 5 to move upward, thereby driving the fixing block 6 to move. After clamping is completed, the lifting cylinder 14 can be activated again to extend to its longest state. At this time, the positioning ring 15, positioning column 5, fixing block 6 move upward, and the electric push rod 7, positioning frame 8, rotating rod 9 and positioning block 10 will also be driven to move upward. Since the preform is restricted and clamped by the positioning block 10 at this time, the preform will also be driven to move upward by the lifting cylinder 14. Then, the motor 17 is activated to drive the positioning column 5 and positioning block 10 to rotate and flip the preform. After flipping, the lifting cylinder 14 is activated to retract. When the preform is in contact with several balls 18 on the support frame 1, it is considered that the flipping is completed.
