The corresponding traditional cast-in-place concrete requires on-site formwork making, on-site pouring, and on-site curing. Concrete prefabricated components are widely used in the fields of construction, transportation, water conservancy, etc., and play an important role in the national economy.

[0003] When manufacturing concrete prefabricated components, a release agent is brushed on the mold and the bottom plate. Steel bars are placed inside the mold, and then a feeding machine is used to inject concrete into the mold. Subsequently, the mold is transported along the track to the rear end for forming. The mold and the prefabricated component are placed at the end of the production line. The solidification time of the prefabricated component is relatively long, resulting in the accumulation of the mold and the prefabricated component, which is inconvenient for taking out the bottom prefabricated component. Moreover, the direct stacking of prefabricated components may cause deformation of the prefabricated components, thereby affecting the product quality. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0027] Refer to Figure 1-8, A processing device for concrete precast components, including a track 1. On one side of the track 1, there is an installation frame 3. At the bottom of the installation frame 3, there are several universal wheels 10. At the bottom of the installation frame 3, there is a rotating mechanism 7. Inside the installation frame 3, there are two parallel screw rods 4. The tops of the two screw rods 4 are connected by a transmission mechanism 5. The surfaces of the two screw rods 4 are both sleeved with sliders 6. Between the two sliders 6, there is a placement rack 8 connected. Inside the placement rack 8, there is a limiting mechanism 9. Between the placement racks 8 and the track 1, there is a guide plate 2. The guide plate 2 and the track 1 are rotationally connected through a connecting frame 18.

[0028] The limiting mechanism 9 includes a limiting plate 11 slidably connected to the placement rack 8. At the bottom of the limiting plate 11, there is a housing 13 fixedly connected to the placement rack 8. Inside the housing 13, there is a sliding plate 14 slidably connected. At the bottom of the sliding plate 14, there is a top spring 15 fixedly connected. At the top of the sliding plate 14, there is a baffle 12 in contact with the limiting plate 11.

[0029] The transmission mechanism 5 includes a transmission gear 20 fixedly connected to the screw rod 4. Between the two transmission gears 20, there is a toothed belt 21 connected. Specifically, the inner wall of the toothed belt 21 is toothed, and the toothed belt 21 meshes with the two transmission gears 20. By driving the two sliders 6 to move synchronously through the toothed belt 21 and the transmission gears 20, it is convenient for the lifting of the placement rack 8.

[0030] The rotating mechanism 7 includes a driven gear 26 fixedly connected to the bottom end of the screw rod 4. On one side of the installation frame 3, there is an outer cover 25 fixedly connected. Inside the outer cover 25, there is a driving gear 23 rotationally connected and meshing with the driven gear 26. At the top of the driving gear 23, there is a handle 24 fixedly connected. Specifically, when it is necessary to raise and lower the entire placement rack 8, only need to rotate the handle 24. The handle 24 drives the driving gear 23 to rotate, and then drives the screw rod 4 to rotate, which is more convenient for the entire device to store precast components and molds.

[0031] This solution has the following working process:

[0032] When manufacturing precast concrete components, release agent is brushed on the mold and the bottom plate. Steel bars are placed inside the mold, and then a blanking machine (not shown in the figure) is used to inject concrete into the mold. Subsequently, the mold is transported along track 1 to the rear for forming. When the mold is transported along track 1 to the end of track 1, the mold slides along guide plate 2 and enters placement rack 8. The mold pushes limit plate 11 to slide to the right, and limit plate 11 is pushed open. After limit plate 11 is pushed open, ejection spring 15 rebounds, and ejection spring 15 pushes slide plate 14 to rise. Slide plate 14 drives baffle plate 12 to rise, and baffle plate 12 blocks the side of the mold. The mold and the precast slab are directly locked. After one layer of placement rack 8 is filled, turn handle 24. Handle 24 drives driving gear 23 to rotate. Driving gear 23 drives driven gear 26 to rotate. Driven gear 26 drives lead screw 4 to rotate. One of the lead screws 4 drives one of the transmission gears 20 to rotate. One of the transmission gears 20 drives toothed belt 21 to rotate, thereby driving the other transmission gear 20 to rotate. The other lead screw 4 starts to rotate, thereby driving two sliders 6 to rise and driving the remaining placement racks 8 to rotate, transporting the remaining placement racks 8 to one side of track 1 for placing other molds and precast components. After all the precast components and molds are placed, push mounting frame 3. Mounting frame 3 drives several molds and precast slabs to be placed in the solidification area. After the precast slab solidifies, press baffle plate 12 and push limit plate 11. Limit plate 11 drives the mold and the precast component to be ejected, and the mold and the precast component are separated, and the processing of the precast component is completed.

[0033] According to the above working process, it can be known that:

[0034] When the mold is conveyed along the track 1 to the end of the track 1, the mold slides along the guide plate 2, and the mold enters the placement rack 8. The mold pushes the limit plate 11 to slide to the right, and the limit plate 11 is pushed open. After the limit plate 11 is pushed open, the ejector spring 15 rebounds, and the ejector spring 15 pushes the slide plate 14 to rise. The slide plate 14 drives the baffle plate 12 to rise, and the baffle plate 12 blocks the side of the mold, and the mold and the precast slab are directly locked. After one layer of the placement rack 8 is filled, turn the handle 24. The handle 24 drives the driving gear 23 to rotate, the driving gear 23 drives the driven gear 26 to rotate, the driven gear 26 drives the lead screw 4 to rotate. One of the lead screws 4 drives one of the transmission gears 20 to rotate, one of the transmission gears 20 drives the toothed belt 21 to rotate, and then drives the other transmission gear 20 to rotate. The other lead screw 4 starts to rotate, and then drives the two sliders 6 to rise, drives the remaining placement racks 8 to rotate, and transports the remaining placement racks 8 to one side of the track 1 for placing other molds and precast parts. After the entire precast part and the mold are placed, push the mounting frame 3. The mounting frame 3 drives several molds and precast slabs to be placed in the solidification area. After the precast slab solidifies, press the baffle plate 12 and push the limit plate 11. The limit plate 11 drives the mold and the precast part to be ejected, and the mold and the precast part are separated. The precast part is processed. Compared with the prior art, after the mold and the precast slab are processed, the mold and the precast part are placed at the end of the production line, and the solidification time of the precast part is relatively long, resulting in the accumulation of the mold and the precast part, which is inconvenient for taking out the bottom precast part. Moreover, the direct stacking of the precast parts may cause the precast parts to deform, affecting the product quality. In this solution, the movable placement rack 8 is used to place the precast parts and the mold, the mold does not accumulate, the bottom precast part is convenient to take out separately after molding, and the mold and the precast part are layered, and the precast part is not easily deformed, ensuring the product quality.

[0035] Further, the bottom of the baffle plate 12 is inclined towards the position of the lead screw 4, the top of the baffle plate 12 is provided with a rounded corner, and the side of the limit plate 11 close to the baffle plate 12 is provided with a chamfer. Specifically, when the limit plate 11 is pulled out, the baffle plate 12 is ejected with the ejector spring 15. After the equipment is used up, push the limit plate 11 with a chamfer, and the limit plate 11 squeezes the inclined baffle plate 12, and the baffle plate 12 descends along the limit plate 11, facilitating the reset of the baffle plate 12.

[0036] Further, the side of the limit plate 11 away from the baffle plate 12 is U-shaped, and the inner wall of the bottom of the limit plate 11 is provided with an inclined extrusion block 19. Specifically, when the mold and the precast part move to one end of the limit plate 11 on the placement rack 8, the extrusion block 19 at the bottom of the limit plate 11 squeezes the mold, facilitating the positioning of the mold and the precast part.

[0037] Furthermore, a plurality of fixing plates 16 fixedly connected to the placement rack 8 are provided at the bottom of the limit plate 11. A return spring 17 is provided between the fixing plate 16 and the limit plate 11. The two ends of the return spring 17 are respectively fixedly connected to the fixing plate 16 and the limit plate 11. Specifically, when the limit plate 11 is pushed open, the return spring 17 is stretched. On the one hand, the return spring 17 provides a clamping force to facilitate the clamping of the mold and the prefabricated parts. On the other hand, when the mold is taken out, the return spring 17 resets, making it more convenient for the equipment to reset.

[0038] Furthermore, a ejector rod 27 is provided between every two adjacent placement racks 8. A cushion block 28 is fixedly connected to the bottom of the ejector rod 27. Specifically, the ejector rod 27 is fixedly connected to the bottom of the placement rack 8. The two adjacent placement racks 8 are supported by the ejector rod 27 and the cushion block 28, reducing the stress on the thread of the lead screw 4 and reducing the wear of the lead screw 4.

[0039] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention.
