Description

Technical Field

[0001] This utility model belongs to the field of construction machinery design technology, and relates to the design of precast concrete pouring machinery, specifically a precast concrete component stacking device. Background Technology

[0002] Precast concrete components refer to concrete components that are prefabricated in a factory or specialized production site, typically including beams, slabs, columns, pipes, walls, and stairs. These components can be directly transported to the construction site for assembly, improving construction efficiency and saving time and costs. After production, precast concrete components need to be stacked. Stacking utilizes vertical space, allowing multiple components to be placed together, thus effectively reducing the space occupied.

[0003] Existing stacking devices for precast concrete components typically use forklifts. However, when using forklifts to transport precast concrete components, the size of the components that the forklift can transport depends on the forklift's lever arm. Since the lever arm of the forklift cannot be adjusted, there is a risk of components falling and getting damaged when transporting larger components. For example, when stacking precast tunnel segments, if the segments are not asymmetrically positioned on the forklift after the forklift has inserted them, they will fall off.

[0004] Chinese patent application CN221853478U discloses a stacking device for precast concrete blocks. This device uses a spreading ring that contracts to compress a return spring. The elastic force of the return spring causes the spreading ring to spring back and press against the inner walls of the through holes on both sides of the precast block, thus handling and stacking the precast components. However, this type of stacking device requires the structure of the components to be compatible with it, thus limiting its applicability. Furthermore, this spring-compression fixing method is prone to component falling and damage. Summary of the Invention

[0027] Example:

[0028] like Figure 1 As shown, a precast concrete component stacking device includes a truss 1, a sliding mechanism 2, a telescopic mechanism 3, and a clamping mechanism 4. The clamping mechanism 4 is connected to the telescopic mechanism 3, the telescopic mechanism 3 is connected to the sliding mechanism 2, and the sliding mechanism 2 is slidably connected to the truss 1.

[0029] like Figure 2 , Figure 3 As shown, the clamping mechanism 4 includes a connecting frame 7, a sliding head 6, a rotating arm 8, a clamping bucket 9, a connecting assembly, an adjusting hydraulic cylinder 5, a bidirectional hydraulic cylinder 14, and a connecting plate 15. The connecting plate 15 is fixed to the top of the connecting frame 7 and is connected to the telescopic mechanism 3. The sliding head 6 is slidably connected to the connecting frame 7. The two sliding heads 6 are symmetrically arranged on both sides of the connecting frame 7. The rotating arm 8 is hinged to the bottom of the sliding head 6. The clamping bucket 9 is fixed to the bottom of the rotating arm 8. The connecting assembly is fixed to the top of the rotating arm 8. The adjusting hydraulic cylinder 5 is drivenly connected to the rotating shaft 19. The two ends of the bidirectional hydraulic cylinder 14 are fixedly connected to the sliding heads 6 on both sides respectively.

[0030] Truss 1 supports the entire stacking device and allows the clamping mechanism 4 to be at a certain height above the ground, facilitating the clamping and transporting of precast concrete components for stacking. Sliding mechanism 2 moves the clamping mechanism 4 on truss 1; sliding mechanism 2 can employ structures such as sliding heads or sliding sleeves. Clamping mechanism 4 clamps the precast concrete components and transports them for stacking. In clamping mechanism 4, connecting plate 15 connects and fixes to sliding mechanism 2, connecting frame 7 is used to install other structures, and sliding head 6 slides on connecting frame 7, thereby moving rotating arm 8 and clamping bucket 9. Adjusting hydraulic cylinder 5 drives rotating component 12 to rotate rotating shaft 19 by controlling the extension and retraction of telescopic rod 13, which in turn rotates rotating arm 8 and clamping bucket 9. Clamping occurs when rotating arms 8 and clamping bucket 9 on both sides rotate inward, and release occurs when rotating arms 8 and clamping bucket 9 on both sides rotate outward. Bidirectional hydraulic cylinder 14 controls the distance between sliding heads 6 on both sides, which in turn controls the distance between clamping buckets 9 on both sides.

[0031] In use, the clamping mechanism 4 is slid over the concrete prefabricated component, and the clamping mechanism 4 is lowered by the telescopic mechanism 3. The telescopic rods on both sides of the bidirectional hydraulic cylinder 14 are controlled to extend outward, and the sliding heads 6 on both sides move away from each other, that is, the clamping buckets 9 on both sides move away from each other. The telescopic rod 13 of the adjusting hydraulic cylinder 5 is controlled to drive the rotating shaft 19 to rotate and drive the rotating arm 8 and the clamping bucket 9 to rotate, and the rotating arms 8 on both sides are controlled to rotate inward, that is, the clamping buckets 9 on both sides are controlled to rotate inward, and the concrete prefabricated component is clamped by the clamping buckets 9. The telescopic rods on both sides of the bidirectional hydraulic cylinder 14 are controlled to retract, and the clamping buckets 9 on both sides move towards the middle, thereby stably clamping the concrete prefabricated component. The clamping mechanism 4 is raised by the telescopic mechanism 3, and the clamping mechanism 4 is slid to the stacking area by the sliding mechanism 2, and the concrete prefabricated component is placed down by the clamping mechanism 4 to complete stacking. The stacking device with such a structure can be applied to different specifications and different shapes of concrete prefabricated components, and can efficiently complete stacking.

[0032] As shown in Figure 1 , the top of the truss 1 is provided with a sliding rail, and the sliding mechanism 2 is slidably connected with the sliding rail. The sliding rail is designed to ensure stable sliding of the sliding mechanism 2. By providing the sliding rail, the connection between the sliding mechanism 2 and the truss 1 is more stable, and the movement is also more stable, reducing the shaking of the clamping mechanism 4 during movement and reducing the possibility of the prefabricated component falling from the clamping mechanism 4.

[0033] As shown in Figure 1 , the telescopic mechanism 3 includes a plurality of hydraulic cylinders, wherein both ends of all the hydraulic cylinders are respectively fixedly connected with the sliding mechanism 2 and the connecting plate 15. The hydraulic cylinders are used to realize telescopic function by the extension and retraction of the piston rod, so as to adjust the height of the clamping mechanism 4. The hydraulic cylinders have the advantages of stable working performance, strong carrying capacity and easy control, and through such design, the stability of the clamping mechanism 4 can be effectively ensured.

[0034] As shown in Figure 2 , Figure 3 , the connecting frame 7 includes two connecting columns 16, and the two sliding heads 6 are slidably connected with the two connecting columns 16 at the same time. The two connecting columns 16 are provided to ensure the stability of the sliding heads 6 and prevent the sliding heads 6 from tilting during movement, that is, to ensure the stability of the clamping mechanism 4.

[0035] As shown in Figure 4 , the rotating arm 8 is an arc mechanism, and the clamping bucket 9 is an L-shaped structure. Through such design, the whole formed by the rotating arm 8 and the clamping bucket 9 can more easily hold the prefabricated component, and the risk of the prefabricated component falling can be reduced. At the same time, such design also improves the applicability, and can clamp components with different shapes and structures.

[0036] As shown in FIGFigure 2 , Figure 3 As shown, the adjusting hydraulic cylinder 5 connecting assembly includes a telescopic rod 13, a rotating component 12, and a rotating shaft 19. The rotating shaft 19 is rotatably connected to the bottom of the sliding head 6, and the rotating component 12 is vertically fixed to the middle of the rotating shaft 19. The telescopic rod 13 of the adjusting hydraulic cylinder 5 is hinged to the rotating component 12, and the rotating arm 8 is fixed to the rotating shaft 19. In this embodiment, two rotating arms 8 are provided, each fixed to one end of the rotating shaft 19. The rotating shaft 19 drives the rotating arms 8 at both ends to rotate, while the rotating component 12 provides a connection fulcrum for the adjusting hydraulic cylinder 5. In use, the piston rod of the adjusting hydraulic cylinder 5 extends and retracts, causing the telescopic rod 13 to drive the rotating component 12 to rotate. The rotating component 12 drives the rotating shaft 19 to rotate, and the rotating shaft 19 drives the rotating arm 8 and the clamping bucket 9 to rotate, thereby achieving clamping or releasing.

[0037] like Figure 2 As shown, a control hydraulic cylinder 11 is fixedly connected to the bottom of the sliding head 6. The telescopic rod of the control hydraulic cylinder 11 faces downward, and a pressure plate 10 is fixedly connected to the end of the telescopic rod. The control hydraulic cylinder 11 drives the pressure plate 10 to move up and down. The pressure plate 10 is used to press the precast components tightly onto the clamping bucket 9, further preventing the precast components from slipping off the clamping bucket 9, ensuring stability during transfer, and thus improving stacking efficiency. Further optimization involves using an elastic material for the pressure plate 10, such as rubber or wood. The pressure plate 10 is controlled by the control hydraulic cylinder 11, which helps maintain the stability of the precast components.

[0038] The two ends of the bidirectional hydraulic cylinder 14 are fixedly connected to connecting flanges 17, and the bidirectional hydraulic cylinder 14 is detachably connected to the sliding head 6 through the connecting flanges 17. The design of the connecting flanges 17 realizes the detachable connection, and the bidirectional hydraulic cylinder 14 can be detachably connected to the sliding heads 6 on both sides through the connecting flanges 17, which makes it easy to replace the bidirectional hydraulic cylinder 14.
