Abstract
Description
Technical Field
[0001] This utility model relates to the field of engineering construction technology, specifically to a precast reinforced concrete component forming equipment. Background Technology
[0002] Reinforced concrete, often simply referred to as reinforced concrete in engineering, is a composite material created by incorporating steel mesh, steel plates, or fibers into concrete to improve its mechanical properties. It is the most common form of reinforced concrete.
[0003] Most existing precast reinforced concrete component molding equipment does not have automatic demolding function. After the precast reinforced concrete component is formed, the mold needs to be opened manually, which results in a large physical exertion for workers in the demolding process. It is not suitable for the production of large or heavy precast components. Utility Model Content
[0004] The purpose of this invention is to provide a precast reinforced concrete component forming device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a precast reinforced concrete component forming equipment, including a support plate, a demolding mechanism on the top of the support plate, and a feeding mechanism on the top of the demolding mechanism;
[0006] The demolding mechanism includes a lower mold, which is disposed on the top of a support plate. Positioning frames are fixedly connected to both sides of the lower mold and the positioning frames are fixedly connected to the top of the support plate. An upper mold is disposed on the top of the lower mold, and a feed pipe is fixedly connected to the top of the upper mold. Mounting frames are fixedly connected to both sides of the upper mold. A threaded rod is internally threaded to the mounting frame, and a first motor is fixedly connected to the bottom of the threaded rod. The first motor is fixedly connected to the top of the positioning frame.
[0007] Preferably, two threaded rods are provided, and the two threaded rods are symmetrically arranged. A horizontal plate is rotatably connected to the top of the two threaded rods. A positioning plate is fixedly connected between the horizontal plate and the positioning frame. The two symmetrical threaded rods can make the upper mold bear force evenly during the lifting process, avoid the upper mold tilting due to force on one side, and ensure the precise alignment of the upper mold and the lower mold.
[0008] Preferably, a mounting plate is fixedly connected to the top of the mounting frame, a support rod is slidably connected inside the mounting plate, the support rod is fixedly connected to the top of the support plate, an arc-shaped plate is fixedly connected to the top of the support rod, and the arc-shaped plate is fixedly connected to the top of the horizontal plate. The support rod plays a guiding role, restricting the movement trajectory of the upper mold and ensuring that the upper mold only moves up and down in the vertical direction, avoiding lateral deviation.
[0009] Preferably, the feeding mechanism includes a placement plate, which is fixedly connected to the top of a horizontal plate. A cylinder is fixedly connected to the top of the placement plate. A stirring blade is rotatably connected inside the cylinder. A second motor is fixedly connected to the top of the stirring blade. The second motor is fixedly connected to the top of the cylinder. The cylinder is used to temporarily store concrete raw materials. The stirring blade rotates under the drive of the second motor, which can continuously stir the concrete inside the cylinder to prevent it from solidifying or separating, ensuring the fluidity of the concrete and facilitating subsequent transportation.
[0010] Preferably, a limiting plate is fixedly connected to the top right side of the cylinder, and a mud pump is fixedly connected to the top of the limiting plate. A third conveying pipe is fixedly connected between the mud pump and the cylinder. The mud pump serves as a power source and draws the mixed concrete from the cylinder through the third conveying pipe, providing power for concrete conveying and solving the problem of inefficient concrete conveying due to its own weight.
[0011] Preferably, a second conveying pipe is fixedly connected to the top of the mud pump, and a first conveying pipe is fixedly connected to the surface of the second conveying pipe. The first conveying pipe is located directly above the feed pipe, and the second conveying pipe and the first conveying pipe form a conveying channel to guide the concrete pumped by the mud pump to the feed pipe.
[0012] Preferably, a fixing member is fixedly connected to the surface of the first conveying pipe. The fixing member is fixedly connected to the top of the placement plate. The fixing member firmly fixes the first conveying pipe to the placement plate to prevent the first conveying pipe from shaking or shifting due to impact force during concrete conveying. This ensures that the first conveying pipe is always kept directly above the feed pipe, ensuring the stability of the feeding position and avoiding material waste or poor feeding caused by pipe deviation.
[0013] Compared with the prior art, the present invention provides a precast reinforced concrete component forming equipment, which has the following beneficial effects:
[0014] 1. This reinforced concrete precast component forming equipment, through its set demolding mechanism, can achieve automatic demolding, reducing the physical exertion of workers in the demolding process, and is especially suitable for the production of large or heavy precast components.
[0015] 2. This precast reinforced concrete component forming equipment, through its feeding mechanism, creates favorable conditions for the subsequent forming of precast reinforced concrete components by ensuring uniform raw materials. During the casting process, the consistent material can more smoothly fill all corners of the mold (between the upper and lower molds), reducing the generation of forming defects such as air bubbles and voids. This improves the dimensional accuracy and internal structural integrity of the components, thereby enhancing the stability and reliability of the formed components. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] This utility model provides a technical solution:
[0025] Example 1:
[0026] Combination Figure 1-2 to Figure 3-4 A precast reinforced concrete component forming equipment includes a support plate 1, a demolding mechanism 2 is provided on the top of the support plate 1, and a feeding mechanism 3 is provided on the top of the demolding mechanism 2.
[0027] The demolding mechanism 2 includes a lower mold 22, which is located on the top of the support plate 1. Positioning frames 29 are fixedly connected to both sides of the lower mold 22. The positioning frames 29 are fixedly connected to the top of the support plate 1. An upper mold 26 is located on the top of the lower mold 22. A feed pipe 202 is fixedly connected to the top of the upper mold 26. Mounting frames 28 are fixedly connected to both sides of the upper mold 26. A threaded rod 24 is internally threaded to the mounting frame 28. A first motor 201 is fixedly connected to the bottom of the threaded rod 24. The first motor 201 is fixedly connected to the top of the positioning frame 29.
[0028] Furthermore, two threaded rods 24 are provided, and the two threaded rods 24 are symmetrically arranged. A horizontal plate 25 is rotatably connected to the top of the two threaded rods 24. A positioning plate 21 is fixedly connected between the horizontal plate 25 and the positioning frame 29. The two symmetrical threaded rods 24 can make the upper mold 26 bear force evenly during the lifting process, avoid the upper mold 26 tilting due to force on one side, and ensure the precise alignment of the upper mold 26 and the lower mold 22.
[0029] Furthermore, a mounting plate 27 is fixedly connected to the top of the mounting bracket 28, and a support rod 23 is slidably connected inside the mounting plate 27. The support rod 23 is fixedly connected to the top of the support plate 1, and an arc-shaped plate is fixedly connected to the top of the support rod 23. The arc-shaped plate is fixedly connected to the top of the horizontal plate 25. The support rod 23 plays a guiding role, restricting the movement trajectory of the upper mold 26, ensuring that the upper mold 26 only moves up and down in the vertical direction, and avoiding lateral deviation.
[0030] Example 2:
[0031] See Figure 5 Furthermore, based on Embodiment 1, the feeding mechanism 3 further includes a placement plate 31, which is fixedly connected to the top of the horizontal plate 25. A cylinder 35 is fixedly connected to the top of the placement plate 31. An agitator 32 is rotatably connected inside the cylinder 35. A second motor 36 is fixedly connected to the top of the agitator 32. The second motor 36 is fixedly connected to the top of the cylinder 35. The cylinder 35 is used to temporarily store concrete raw materials. The agitator 32 rotates under the drive of the second motor 36, which can continuously agitate the concrete inside the cylinder 35 to prevent it from solidifying or separating, ensuring the fluidity of the concrete and facilitating subsequent transportation.
[0032] Furthermore, a limiting plate 38 is fixedly connected to the top right side of the cylinder 35, and a mud pump 39 is fixedly connected to the top of the limiting plate 38. A third conveying pipe 301 is fixedly connected between the mud pump 39 and the cylinder 35. The mud pump 39 serves as a power source and draws the mixed concrete from the cylinder 35 through the third conveying pipe 301 to provide power for concrete conveying and solve the problem that concrete is difficult to convey efficiently due to its own weight.
[0033] Furthermore, a second conveying pipe 37 is fixedly connected to the top of the mud pump 39, and a first conveying pipe 34 is fixedly connected to the surface of the second conveying pipe 37. The first conveying pipe 34 is located directly above the feed pipe 202. The second conveying pipe 37 and the first conveying pipe 34 form a conveying channel to guide the concrete pumped by the mud pump 39 to the feed pipe 202.
[0034] Furthermore, a fixing member 33 is fixedly connected to the surface of the first conveying pipe 34. The fixing member 33 is fixedly connected to the top of the placement plate 31. The fixing member 33 firmly fixes the first conveying pipe 34 to the placement plate 31 to prevent the first conveying pipe 34 from shaking or shifting due to impact force during concrete conveying. This ensures that the first conveying pipe 34 is always kept directly above the feed pipe 202, ensuring the stability of the feeding position and avoiding material waste or poor feeding caused by pipe deviation.
[0035] In actual operation, when this device is used, the second motor 36 is started first. The second motor 36 can drive the stirring blade 32 to rotate. At this time, the raw materials inside the cylinder 35 can be mixed evenly, which is beneficial to the subsequent molding of reinforced concrete precast components. Then, the mud pump 39 is started. Under the action of the mud pump 39, the raw materials inside the cylinder 35 can be discharged through the third conveying pipe 301, the second conveying pipe 37 and the first conveying pipe 34. Under the action of gravity, the raw materials fall through the feed pipe 202 between the upper mold 26 and the lower mold 22.
[0036] After cooling for a period of time, the reinforced concrete precast components inside the upper mold 26 and lower mold 22 are formed. When demolding is required, the first motor 201 is started. The first motors 201 on both sides are controlled by the same switch. At this time, the threaded rods 24 on both sides rotate synchronously and drive the upper mold 26 to move upward, which can achieve the purpose of automatic demolding and reduce the physical exertion of workers in the demolding process. It is especially suitable for the production of large or heavy precast components.
